The present invention relates to typographical machines and more especially to line casting machines of the general class shown and described in U. S. Letters Patent $36,532, granted September 16, 1890, to O. Mergenthaler, wherein molten metal is forced into a slotted mold against a composed line of character-bearing matrices to produce a printing slug or type bar which is subsequent y removed from the mold by an ejector which is advanced against the rear edge f the sing and pushes it edgewise from the mold into a galley.

In t e operation of machines of this class, it frequently becomes necessary to vary the length of the mold slot in order to produce slugs of different lengths to accord with the measure of the body or column to be printed. Machines of this class, in practice, are provided with mold wheel or carrier on which a plurality of molds are mounted so that one or another thereof may be broughtinto use, and the different molds may have casting slots which differ in length and height so that slugs of several different sizes, according to the requirements of the work in hand, can be cast by merely bringing one or another of the molds into active position. However, the requirements of the various classes of compositicn will not always enable a sufficient assortment of molds of different sizes to be always present on the mold carrier, so that frequently it becomes necessary to remove one or more of the molds from the mold carrier and re place it r them with another mold or. other molds, or one or more of the moldsmay be partially dissembled and provided with a liner of a difierent size, such liner being the usual changeable mold member which determines the length of the casting slot therein.

llerei'ioforc, such bringing into operative position of a differentmold already mounted in the mac he or such changes in the molds or the liners thereof, has required the opera-'- tor perform subsequent operation where- J 1 a an 1CLO1 olaue of tie pro-per widthto pass through theslot of the selected or altered mold and to push out the slug cast therein, would be set manually into operative )osition and the erformance of this e'ector blade selecting or adjusting operation has dependent upon the thoughtfulness or attentron of the operator. In consequence, it frequently happens that the operator, through.

carelessness or inattention, forgets to make t ie e ector blade settmg or adjustment to 'accord with the selected or altered mold, and

upon starting the machine into operation, 7 i

such has resulted in the presentation of an improper ejector blade to the mold when the latter reaches the ejecting position, and if such blade is too long to enter the mold slot, such ejector blade wouldj am against the back of the mold liner and, in many cases, cause ser1- ous damage.

v it-tempts have been'made to provide safety means to protect the machine from damage due to failure of the operator to bring into use an ejector blade of the proper width to conform with the changeo or altered mold,

but such safety means-as have been proposed 7 have been found deficient or otherwise unsatisfactory for practical use, due to the mechanical intricacies thereof 'or to their failure to provide afull measure of protection to the machine.

- T he primary obj ectof the present invention is to provide an improved mechanism which will overcome the above mentioned deficiencies and which will serve effectively not only as a safety means to protect the molds and linersiand other parts of'the machine from damage but which will also render the selection of the required ejector-blade or the proper setting of the ejectormechanism automatic each time a mold having a slot of different length er a mold liner of differentlength is brought into use.

A more particular object of the invention is to provide an automatic ejector se setting mechanism which is compelled to come into operation each time the operator lecting v rotates the mold wheel, which mold wheel rotation always precedes the bringing of a different mold thereon into use or the introduction of a new mold on the mold wheel or changes in the length of the liners of the molds thereon. Y.

A further object of the invention is to provide ejector selecting or setting mechanism which is so constructed and arranged that failure to operate it in the proper'manner will prevent operation of the ejector until the correct operation of the ejector selecting or setting mechanism has been performed.

To these and other ends, the invention consists in certain improvements and combinations and arrangements of parts all as will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.

The preferred embodiment of the invention is shown in the present instance and will be hereinafter described in detail, but it is to be understood that the invention is not restricted to the particular construction shown, since equivalent constructions are contemplated and such will be included within the scope of the claims. In' the present instance, the invention is shown and will be hereinafter or setting mechadisconnected describech'for example, as applied to multiple blade ejector mechanism of the general form shown and described in my prior U. S. Patother forms of multiple "lads ejectors such as those now in use.

. In the present instance, 1 represents the usual mold slide of a line casting machine of the general class hereinbefore referred to, such mold slide being mounted for example in the usual way and having the ejector mechanism mounted therein,the mold slide having as usual a hub 2 projecting laterally there from and rotatably supporting the usual mold wheel 6, 3 represents theusual mold gear arm forming part of the main frame of the machine, it being supported toward its forward end by the usual. upright post or bracket 4, and 5 represents a cross arm or brace,'forming part of the main frame of the machine. The mold wheel 6, in machines of this class, is usually constructed and arranged to carry four molds 6, the mold wheel and the molds thereon being constructed and arranged for example as shown generally in U. S. Letters Patent No. 758,103, granted April 26,1904, to W. H. mounted on a shaft 8 supported in the upright post or bracket 4 meshes witl the peripheral gear teeth on the mold wheel and serves to rotate the latter, the rear end of the shaft 8 being driven at appropriate times and to Randall. A pinion 7 the proper extents by the driving mechanism of the machine to carry the mold on the mold wheel which is in use from normal ejecting position to casting position and from the latter position to normal ejecting position, means being usually provided in machines of this class for holding the mold wheel against turning inadvertently out of proper timed relation with the machine during the intervals between its rotating movements, and the pinion 7 serves as means by which the mold wheel may be rotated independently of its operating shaft 8 in order to bring a diiferent mold on the mold wheel into operative position, it being common in machines of this class to provide a locking pin on the pinion operating shaft 8 and to provide the rear face of the pinion 7 with a recess in which such pin may engage to normally connect the pin ion to its operating shaft, the pinion being movable axially on its'operating shaft to disengage it from the locking pin and rotatable while so disengaged wh reby it may rotate the mold wheel. into the desiredposition.

According to the present invention. the pinion 7 is rotatable on its drivmg shaft 8 but is held from longitudinal movement thereon, and i is operatively connected and with respect to the shaft 8 by a pin 9 projecting forwardly from a clutch collar 10, the latter being splined on the shaft 8 so that it will always rotate therewith but may move axially thereon to engage and disch nge the pin 9 with respect to a recess or hole 11 formed in the rear face of the pinion 7. Normally, the clutch collar 10 will be in forward position with the pin 9 thereon in engagementwith the recess or hole 11 in the pinion '7 so that the latter will be driven by the shaft 8 and will be held against rotation independently thereof, but when the'cluich collar 10 is shifted. rearwardly, the pin 9 thereon will be withdrawn from the recess or hole 11, thereby disconnecting the pinion 7 from the shaft 8 and the pinion will then be free for independent rotation to bring any desired mold on the mold wheel into operative position. The means shown in Figs. 1, 2. 3 and 8 for controlling the driving connection between the pinion nd the shaft 8 comprises a clutch shifting arm 12 having a yoke hereon provided with oppositely arl5) ranged pins 1% which engage in a circumferential groove 15 in the clutch collar 10, the arm 12 being' guided for reciprocation longitudinally of the shaft 8 by abracket plate 16 secured by screws or other suitable means to the upright post or oraclret 4. The arm 12 is nvotally connected to the upper end of a vertical lever 17 which latter is pinned or otherwise fixed at its lower end to one end of a horizontal shaft 18 rotatably mounted in the cross arm 5 of the machine frame, the lever 1'7 being constantly urged forward by a coil spring 19 which encircles the shaft 18, one end of the spring being fixed to the machine frame and its other end acting on the lever 17. The other end of the shaft 18, as shown in Fig. 3, has vertical. lever 20 pinned or otherwise fixed tlnireto and the forward face of this lever is opposite to and in a position to contact with the rear end of an adjustable setscrew 21. the latter being carried in a suitable bracket which is pinned or otherwise fixed to a shaft-23. the latter extending lo gitudinallvfrom the front to the rear of the mold slide along or beneath its lower edge and being guided to slide longitudinally in bearings 89 and 10 formed in a bracketll which is fixed by screws or otherto the mold slide 1. According to this construction, the spring 19 normally acts to swing; the lever 17 also the arm 12 forwardly, ti ereby holding the clutch collar 10 in its forward position and the pin 9 thereon in engagement with the recess 11in thepinion 7 so that the latter will be normally locked to its driving shaft 8, and the 3l1'1l911 7 cannot be turned independently of the shaft 8 until the clutch collar 10 has been shifted rearwaroly into the position shown in Fig. 2, as by rearward movement of the set screw 21 to carry it into engagement with the lever2O and to swing the latter rearwardly from its normal position shown in Fig. 3. The means by which the set screw 21 is thus shifted will b-efore referred to. For the purposes of the pr sent invention. it is deemed SLllllClQlll] to describe it as comprising an ejector slide '24 mounted to reciprocate between upper and lower guide rails 25 and 26 formed on the molc. slide 1 and 8X aiding longitudinally of the mold slide so that the ejector slide may reciprocate forwardly and rearwardly under the action ofth-e connecting link 27 which reaches toward the rear of the machine where it is acted upon at appropriate times by the main driving cams in the well-known manner. A master blade 28 is secured to one side of the ejector slide 24 and extends forwardly ther om it.- having hapedextension 29 pro ecting forwa dly from its forward edge which serves as a key to engage in a correspondingly shaped recess in the rear edge of any one of of ejector blades 30 when the master blaoe 28 is in register or alignment with'such ejector blades. The ejector blades 30 are contained within a magazine or blade box 31 which is movable transve 'sely of the path of movement of the master blade 28 to bring any one of the ejector blades into register with such masterblade, the magazine or blane hon being; mounted for this purpose between upper and lower bars 82 which are guided to slide longitudinally in the mold slide 1 and are connected at their rear ends by a yoke or cross bar 33 having; a lug: 3d projecting ally therefrom and by which the bars 32 are reciprocated. The sides of the bars toward the upper and lower edges of the blade box 31 are formed ith obliquely extending ribs 85,.and these rib cr ase correspondinf obliquely e7;- tc. grooves 37 in the upper and lower edges of the bla box. The lug or projection 34 for shifting: the bars is arranged to be engaged by an arm '36 which is pinned or otherwise fixed on the shaft 23 so that itwill move forwardly or r-earw lly therewith. It

2 will sh ft forwill be seen that the a, wardly or rearwardly wi iin the mold slide 1 in accordance with corresoonding movements oia zes 3G in the blade box are of different .mold slide and to.

lengths in the molds that may be used, and

the recesses in the rear edges of the ejectorblades are all on a common level so that any one of them may receive the key or projection 29 on the master blade, according to the lateral position into which the blade boX is shifted. It will be understoodthat the master blade 28 is withdrawn to its rear position when the blade box is shifted to bring a selected ejector blade therein into use. A guide post 38having a portion thereon of a shape co responding within the recesses 1n the rear edges of the ejector blades so that it may enter such recesses is shown immediately beside the master blade 28, this guide post insuring exact-registration of the recess of any selected ejector blade with the key or extens on 29 on the master blade. In Fig. 8, the master blade is shown in operative engagement with the smallest or narrowest ejecto: blade, and the ejector slide 24 is shown in its forwardly advanced position, thus illustrating the manner, in which an ejector blade is moved forwardly to extend through the cavity of the mold.

Forward or rearward movement of the shaft 23 to shift the blade box 31 to bring one or another of the ejector blades 30 into register and operative relationship with the master blade 28 is accomplished, as shown in F ig. 8, by an operating lever 42 arranged at the front of the machine, this lever being pivoted intermediately of its l ngth at 43 to an extension 44 of the bearing bracket 41, this operating lever being connected to the forward end of the shaft 23 by a link 45 which is 'pivotally connected to the shaft 23 and to said operating lever. The operating lever 42 normally occupies the full line position shown in Fig. 301 the position shown in Fig. 8 but may be swung forwardly into the dotted line position shown in'Fig. 3. When the lever 42 is in its normal position, the set screw 21 will be in its forward position beyond the lever 20 and hence the pinion 7 will be locked by the clutch collar 10 to its driving shaft 8, so that the mold wheel 6 cannot be rotated to bring a different mold thereon into operative position unless the clutch collar 10 is shifted rearwardly to withdraw the locking pin 9 thereon from the recess 11 in the mold turning pinion. To accomplish this, the operating lever 42 is swung forwardly about its pivot 43 from the full line position to the dotted line position shown in Fig. 3, such movement of the oper ating lever causing the shaft 23 to be moved rearwardly so that the screw 21 carried thereby, during the latter part of the forward swing of the operating lever, will contact with the front face of the upper end of the vertical lever and will then swing the lever 20 rearwardly; The rearward of the upper end of the lever 20, as will be seen from Fig. 2, will rotate-the shaft 18 pin 9 on the clutch collar swing against the action of the spring 19 and in a direction to swing the lever 17 rearwardly,

thereby drawing the arm 12 and the clutch collar 10 rearwardly and. thereby withdrawing the pin 9 on the clutch collar from the recess 11 in the pinion 7, and the latter will then be unlocked or free to turn on the shaft 8 and it may be revolved to rotate the mold wheel to bring any desired mold thereon into operative position or to bring a mold thereon from normal ejecting position to the upper horizontal position where it may be replaced by another mold or may be altered to contain a liner ofdiiferent length. In the construction shown in Figs. 2, 3 and 8, the operating lever 42, when pulled forwardly to its full extent, as shown by the dotted lines in Fig. 2, will lock he shaft 23 against forward or return movement since the link in 0011-, junction with the end of the lever 42 to which it is pivoted forms a toggle the middle pivot of which passes beyond the center line between the pivot 43 and the pivot by which the link 45 is connected to the forward end of the shaft 23, so that the pinion 7 will be thus maintained in unlocked relation with its driving shaft 8 while the mold wheel is being turned, and after the desired mold has been brought into operative position by rotation of the mold wheel, or the operation of mounting a new mold on' the mold wheel or of inserting a liner of different length in a mold'on the mold wheel, which latter operations also involve rotating the mold wheel to carry the mold to be replaced or altered from the normalejecting position to casting position and to return such mold to its normal ejecting position, the pinion 7 is again connected to its driving shaft 8 by properly aligning the recess 11 in the pinion with the 10 and then swinging the operating lever 42 back to its normal rearward position, the consequent forward movement of the shaft 23 causing the set screw 21 to recede from the lever 20 so that the latter and also the lever 17 are free to swing forwardly under the action of the spring 19, the forward swing of the lever 17 shiftingthe clutch collar 10 forwardly and thereby causing the pin 9 thereon to enter the recess 11 in the pinion.

Machines of this class are usually provided with a control or starting handle 46 which, as shown in Fig. 8, is pivoted to the machine frame at 46 and is connected by a toggle 46 to bars 146, the rear ends of the latter engaging a clutch lever 47 pivoted on the machine frame and controlling themain drivring clutch of the machine so that when the handle 46 is pushed rearwardly the main driving clutch is disengaged and when said handle is pulled forwardly, the bars 146 are drawn forwardly and, the main driving clutch is engaged to start the machine into. operation. Means is provided by the present inventionfor preventing starting; of the machine unless the operating lever d2 for setting the eject-or mechanism has been returned to its normal position. It will be obvious that should the operator neglect to return the operating handle 1.2 to normal pr on so as to effect reengagement of the pi 9 in the recess 1101" the pinion 7 before starting the machine by pulling the control handle -6 forw rdly, the machine would operate l isual way except that the mold wheel, n on is driven by power transmitted it through the usual pinion shaft 8, would be disconnected. Under such conditions, the mold wheel would to bring selected mold into position in front of the usual metal pot and to align the matrices for casting, but the mold at the top of the mold wheel, which would u W be of improper size in leng h. or hr 111- of its slot or otherwise,

would be in position, so that serious damage might occur to parts of the machine, or a metal squirt might result and endanger the operator. To prevent such an occurrence, a depending arm 43 is pinned or otherwise fixed to the forward end of the reciprocatory shaft 23. its lower end overlying the forward ends of the rods 1&6, By this arrange-- ment, when the operating handle 42 is pulled forward to move the shaft'23 rearwardly to disengage the pin 9 from the recess 11 in the pinion 7, the overlying arm 48 will block the rods 146 against any inadvertent forward movement of the machine control handle 16, and hence the main driving clutch of the machine cannot be thrown into engagement to the machine until the operating handle 42 has been pushed back to normal position.

The present invention provides means for automatically selecting the proper ejector blade 30 to correspond with the length of the ot in the mold which is brought into opposition, and such means will now P described.

as top of the mold slide 1 carries a jcr forwardly. A projection 58 :Yardly from the arm 36into a poion engage stop pin 59 which is fixed to and projects laterally from the selector fine to control latter in its forward not be rotated bracket 49 which is pivoted on said slide by ng acting to constantly urge the se movement under the tension of the spring 54. The upper end of the arm 36 has a horizontal and forward extension 60 and the forward end of this extension is provided with a series of steps 61 which extend in a'-' row obliquely to the length of the extension 60 r which the lug 341 on the yoke 33 projects.

In consequence, rearward movement. of the shaft 23 and the arm 36 will shift the'lug 3 1 from a position in engagement with the rear end of the aperture 65, as shown for example in Figs. 5 and 6, to a position in engagement with the forward end of this aperture as shown in Fig. 1, and owlng to theconnection of the lug 3 1 through-the yoke 33' and slidv able bars 32 and-the oblique ribs 35 thereonwith the blade box 31, the latter will be moved into one of its extreme lateral'positions so that one or another of theend ejector blades therein, preferably the wide'stone within the blade box 31, will be in register with the master blade 28. The arm 36 carries a roller 136 at its upper end, and the bracket 49fis formed with a track or cam surface 13?, this roller and cam surface being so arranged that as the arm 36 shifts rearwardly from. the position shown in Fig. 5 to that shown in Fig. 1, the roller 136 willengage the cam sur face 137 and will act thereon to swing the bracket 49 upwardly from its forwardly and.

downwardly inclined position shown in Fig 5 to its upper, approximately horizontal position shown in Fig. 1. It will be under.- stood, from what has been already stated, that the forward movement of the operating lever 42 which shifts the arm 36into the rear position shown in Fig. 1, disengages the driving pin 9 from the recess 11 in the mold turning pinion 7, so that the mold wheel may then be rotated to bring another mold into operative or active position. After the de- 7 sired mold has been brought to vertical position' in front of the ejectonwhich may be accomplished by turning the thenunloclred pinion 7, the return of the operating lever 42 to normal position, which must take place as previously stated, to permit startingof the machine, moves the shaft 23 and the arm 36 thereon-forwardly, and during the initial part of such forward movementofthe-arm.

which moves for 36, the roller 136 thereon, wardly with the arm 36, will disengage from the cam. track 137 on the pivot-ed bracket 49 so that the latter will be no longer supported in its upper or horizontal position but will tilt downwardly about its pivot 50, under the influence of gravity so that it assumes a posi tion such as that shown for example in Fig. 4. Meanwhile or during this forward movement of the arm 36, the upward projection 58 thereon will move forwardly and thus allow the spring 54 to move the selector finger 53 forwardly since the pin 59 on the selector finger is then allowedto advance forwardly, and as soon as the roller 136 on the arm 36 has moved forwardly sufficiently to al ow the bracket 49 to tilt downwardly about its pivot 50, the selector finger 53 will have advanced forwardly to an'extent sufiicient to cause a fee'ler finger 68 on its forward end to project into a recess 67 in the liner 66 of the mold which occupies ejecting position.

In carrying out the invention, the mold liners of different lengths which, as usual, are changeable to vary the length of theslot or casting cavity in theimold, are provided with recesses of difierent lengths vin their rear edges to cooperate Wlt-ll the feeler finger 68. The left hand liners of molds as com-J monly used in machines fof this class are usually of varylng lengths according to the length of the slugwhich it is desired to cast,

while the right hand liner is usually constant p in length or, in other words, the right hand end of the mold slot is always located at the same point. In F igs.1, 4 and 5, the left hand liner 66 which, in each instance, isv of the same length, is shown in position in the mold positioned vertically in front of the ejector blade, which is the normal position in which the operator would set the mold before starting the machine,this liner being shown cut away along its rear edge to form a recess 67 having a shoulder 167 at one end, while the liner shown in Fig. 6 is relatively longer and it has a recess 67 in its rear edge which is relatively shorter than the recess 67 of the shorter liner, said recess 67 having a shoulder 167 at one end. Each of the left hand liners to be used with the molds, in carrying out the present invention, contains such a recess, a group of these liners being shown in Fig. 11, the liners being of different lengths and the lengths ofthe recesses in the rear edges thereof varying, in the present instance, inversely according to the lengths of the liners, and directly according to the lengths of the mold slots produced by such liners and to the widths of the ejector blades which'conform therewith.

When the bracket 49 tilts downwardly due to the forward movement of the roller 136 carried by the arm 36, the feeler finger 68 on the forward end of the selector finger 53 swings downwardly in the recess 67 or 67 in the rear edge of the liner 66 until it stops against the end or shoulder 167 or 167 of the recess, it being understood that the the operating lever 42 back hangs, to shift the forward movement of the arm 36 which carries the upper projection 58 thereon forwardly in front of the pin 59 on the selector finger 53 allows the latter to move forwardly to carry the feeler finger 68 into the recess in the rear edge of the liner 66 before the roller 136 disengages from and allows the bracket 49 to swing downwardly about its pivot 50, so that when this downward swing of the bracket 49 takes place, the feeler finger 68 will move downwardly while projecting into the recess in the rear edge of the liner. Fig. 4 represents the relative positions of the parts when the operating lever 42 has been partially returned from its forward posi tion and the shaft 23 has moved forwardly to a point where the roller 136 on the arm 36 has disengaged from and hence no longer supports the bracket 49. During the forward movement of the arm 36 from the position shown in Fig. 1 to that shown in Fig. 4, the selector finger 53 advances to project the feeler finger 68 into the recess in the rear edge of the mold liner 66, as stated, until the pin 56 fixed to the selector finger 53 abuts against the forward end of the slot 57 in the bracket 49, thus arresting the forward movement of the feeler linger 68 under the action of the spring 54., and the downward swing of the feeler linger 68 takes place freely in the recess in the mold liner 66 until it comes to rest on the shoulder 167 at the end of such recess, it being understood that the extent of downward swing or tilt of the bracket 49 and selector finger 53 will vary in accordance. with the length or extent of the recess 67 in the mold liner. This downward swing of the bracket 49 and selector finger 53 also brings the lower end of the pawl 62 into a position opposite to or in front of the stepped forward end 61 on the arm 36, the height of thelower end of the pawl 62 relatively-to the steps 61 depending on the length of the recess in the rear edge of the liner which controls the extent of downward swing of the bracket 49 and selector finger 53. Further movement of to normal position further advances the arm 36 forwardly, causing the gravity pawl 62, the lower end of which is engaged by 'an'appropriate step on the forward end of the arm 36, to rock about the rear end of the stop screw 64 as a fulcrum, the upper end of the pawl 62 being thereby swung rearwardly and acting through its pivot pin 63, on which the pawl selector finger 53 rearwardly against the action of the spring 54.

Upon the complete return. of the operating I cu "- register wi ample in "be allowed to thus allowed the arm 36 causes then occupying the position shown in Fig. 5. it will be apparent, from l ig'. 4, that the orward movement of the arm 36 has not cached the point where it will shift the ector blade box 31 since the lug 34-, through which the ejector blade box is shifted, has not been engaged by the rear wall of the aperture 65 in the arm 36, and in Fig. 5, the log 3% has been engaged by the rear wall of the aperture 65, and in carrying outthe invention, the aperture 65 is so positioned that th lug 3% will be merely engaged by the rear wall of said aperture when the first or lowermost step 61 is in engagement "with the pawl 62 and the arm 86 has been moved forward by return of the operating lever 42 sufficiently to withdraw the teeler finger 68 from the recess 67 in the mold liner 66.

Means is provided for positioning and locking the master blade 2'8 longitudinally during the ejector blade changing operation, in order to insureproper engagement of a selected ejector blade therewith. The construction shown. "for this purpose comprises a cam block 69 which is pinned or otherwise fixed to the rear end of the shaft 23 a the mold slide 1, as shown in 1, is provided.

with a vertically extending recess 70 covered 1 by a plate 71 to form a vertical guide chan nel for plun er or bolt 72, the latter having a rearward extension73 which carries con tact shoe, preferably in the form of a roundnose set screw 74. A stop pin 75 is lined in the side of the mold slide and projects into a vertically extending recess 76 in the bolt 72 to prevent dropping of e bolt out of its guide channel 70. wardly beyond the cover plate 71 and .a spring 77 is secured to a pin 78 fixed in the upper end of the bolt 72, the other end of the spring being attached to a pin 7 9 secured The bolt 72 in the cover plate, tl "ring acting con stantly to urge the olt master blade28 of the vided with a notch 80 s lower 0 the forward wall of which is preferably inclined or bevelled as shown in 8, and the bolt 72 has a correspondingl s aped tongue 81 which is offset laterally from one side thereof so that it underlies the notch 80 and is engageable therewith when the bolt 72 is raised,

Then the shaft 23 is in its forward or normal position, the tongueSl on the bolt 72 will be disengaged from the notch 80 in the master blade 28 since the contact shoe 7 4 on said bolt will then rest on the lower face 69 of the cam block 69, and the master blade 28 will then be free to reciprocate without obstruction by the bolt lVhen the shaft 23, however, is pushed to the rear, due to the swinging of the operating lever 42 forwardly in order to release l e mold turning pinion 7 and permit the setting up of a different mold on the mold wheel, the bolt '?2 be lifted b the rid-ins of the inclined or ra sod C) b c 1 v 7" i +1 face 69 or the cam block 69 against u1e con tact shoe or screw 74 ano. the tongue 81 on the bolt 72 will then be engaged in the notch 80 in the lower edge of the master blade Such engagement of the tongue on the colt 72 with the notch 80 in the master blade serves to lock or retain the eiector slide 24 against forward movement whenever the operating lever 42 stands in the forward position, and the bolt 7 2 also serves as a locating means for the master blade 28, since the position of the notch 80 therein is such that when it registers with he bolt 72, the extension 29 on the master blade 28 will lie in eXacttransverse alignment with the similarly shaped extension on the guide post 38 and the extension 29 on the master blade will therefore be in exact transverse alignment with the correspondingly shaped recesses in the rear edges of the ejector blades 30 to insure accurate engagement therewith.

Means is preferably provided to insure the complete return of the operating lever 42 to normal position aft-er each operation thereof, such means in the present instance comprising a tension spring 82 which is secured at its forward end to a pin 83 on the bracket 41 attached to the mold slide 1 and fastened at its rear end to a pin 84 which i to a plate 85, the latter being secured to the arm 36, the tension of the spring 82 acting to constantly urge the arm 36 and the shaft 23 to which it is fixed, forwardly. This spring will insure the complete return of the ooeratin lever 42 to normal position in the event that the operator should swing the opi 1 1, 3.1 J. crating lever 42 sufiiciently to unlock the roggle formed by it and the link but fail to complete the return movement of the operae lng lever to normal POSltlOIL In the modification shown in Figs. 9 and seciu'ed' said shaft.

10, the operating lever 42 is connected di rectly to the shaft 23, thus dispensing with the link 45 used in the previously describcr construction. In this modification, the spring 82 performs the same function of urg ing the operating lever 42 back to normal position except that, in the absence of the looking link used in the previously described construction, the spring 82' will always tend to return the operating lever 42 to normal po-- sition, thus making it necessary for the operator to hold the operating lever 42 forwardly while turning the mold pinion 7 incident to the operation of changing the mold, this arrangement having the advantage that it automatically returns the operating lever 42 to normal position after each mold changing operation.

in the construction shown in F 9 and '40, the pin 9 must be disengaged from the recess 11 in the mold wheel turning pinion 'Z'before the mold wheel 6 can be revolved to bring another mold into action, as in the previous construction. In order that the pin 9 may be thus disengaged from the pinion 7 but not until the operating lever 42 has been given a full forward stroke, the levers 17 and 20 of the previously described construction are replaced by levers S6 and 87. The lever 86 is pivotally connected at its upper end by a pin 88 to collar 89 secured to the shaft 28 and the lower end of this lever is pinned or otherwise fixed to one end of the 18. A short crank 90 is pinned or otherwise fixed to the other end of the shaft 18, it extending downwardly therefrom and carrying a crank pin 91 which operates in a slot in the lower end of the lever 87. The

lever 87 is mounted to rock on a pivot pin 92 which is 1 :-:ed in and supported by the arm 4 of he maclnneframe, and the upper end of the lever 8"? is pivotally connected to the clutch arm 12 which, as in the previously described construction, has an upwardly extending yoke wnich operatively engages the clutch collar 10 which carries the pin 9.

In this modified construction, pulling of the operating lever 42 forwardly causes the shaft 23 'to move rearwardly and such rearward movement of the shaft 23 swings the upper end of the lever 86 rearwardly, thereby causing rotation of the shaft 18 and with it the crank 90, both of whichare secured to Movement of the crank 90 will then produce a forward movement of the lower end of thelever 87 about its pivot pin 92 and the upper end of the lever 87 will therefore move rearwardly, thereby shifting the clutch arm 12 and the clutch collar 10 and pin 9 rearwardly, thus disengagingthe pin 9 from the recess 11 int-he pinion 7. The

the pinion 7 will be considerably slower while i the operating lever 42 is being swung for wardly, and preferably and as shown, such disengagement of the pin 9 from therecess 11 in the pinion will not be complete until the operating lever 42 has been moved into its full forward position, whereupon the 11 has again been brought into register. with i the pin 9, such register of the recess 11 and pin 9 taking place when the next mold on.

the mold wheel has been brought into operative position. As soon as the recess 11 comes into register with the pin 9L the operating lever 42, under the action of'the spring 82, will automatically swing back to normal position and the shaft 23 will correspondingly move forwardly, carrying with it the arm 36. which latter will bring about automatic selection of the proper ejector blade 30 in the same manner as in the construction previously described. The general operation of automatic ejector selecting mechanism constructed as hereinbe e described is as follows: Assuming that adjustable liners for the molds are prota-e vided in their rear edges with recesses 67 or 6'7 of different lengths which vary in versely according; to the lengths of these liners and that the ejector blade 'boi; of the ejector mechanism contains e ector blades'of different widths varying according to the clifferent lengths of the mold slots obtained by the use of the dlfierent length ad ustable liners, in order to rotate the mold wheel to bring a different mold thereon into operative position or to, enable mold thereon to j j .1 ,H .j:j fr I. 0e relLaced finale? m havlnb a C e lever 42 and becoming disengaged from said ent length slot or casting cavity or-to enable the adjustable liner of a mold onthe mold .wheel to be changed for one of a different length and to automatically bring into op- A era-tion an ejector blade of a proper width to conform with the length of the slot in the meld brought into operative position; it is only necessary for the operator to pull the operating lever 42 to its full forward position and to return or allow this operating lever to return to its, normal rear position.

'l he pulling forward of the operating lever 42 moves the shaft 23 rearwardly, carrying h cam block 69 with it and thereby actuatne bolt 72 to position the master blade .1: ejector blade shifting operation and odrithe master blade in such position and the rearward movement of the shaft 23 dud also moving'the arm 36 rearwa'rdly, the latter portion of the rearward movement of this arm causing it'to pickup the lug 34'and to move such lug rearwardly, thereby causing the bars 32 of the ejector mechanism to be drawn rearwardly and causing the ribs 35 on said bars 'actine; on the ejectorblade box 31 to' shift said box laterally to one of its extreme lateral positions where, for example, the widejector blade 3O therein is brought into register or longitudinal alignment and into operative engagement with the master blade 28. he latter-portion. of such rearward movement of the arm, 36'also causes the roller 136 thereon to engage the cam face 137 on the vertically swingable bracket 49, cans-'' ing the latter,togetl1er with the selector finper 53 to swing upwardly into the position shown in Fig.- 1 and the 'final'portion of the rearward movement of the arm 36 will cause "the upwardly projecting portion 58 thereon to engage the pinv 59 on the selector finger 53 and to slide the latterrearwardly against the action of the spring 54 into the position shown in Fig. 1. the .feel'er finger 68 on the forward end bf the selector finger being then retracted from the recess 67in the rear edge of thead ustable mold liner; 6-6 so that this J feeler finger will not obstruct rotation of the mold wheel 6. The forward swing of the operating lever 42 also acts tounlock the mold wheel turningpinion 7 from its drivinn shaft 8'so that the mold wheel fnay be turned. to effect the mold changing or alterinn operation, the clutch collar 10 in Figs. f

l to 8.,'incll.isive-,-beinp; shifted rearwardly to disengage the-pin 8thereon from the recess 11 in the pinion 7 during the latterportion of the forward swing" of the operating lever 42. due to the engagement of the set screw 21 moving rearwardly with the shaft 23 with the upper end of he lever 20, and the clutch collarlO Figs; 9 and lO'being progressively withdrawn from the recess-11. in the pinion? during the forward swine of the operating cannot bestarted inadvertently into operation by the starting handle46, and since the mold wheel turning pinion 7 is disconnected from its driving shaft 8, the mold wheel maybe rotated to bring another mold thereon into operative positionor to bring a mold thereon from the normal vertical or ejecting position to the upper horizontal or. casting position for replacement by another mold or for changin of the length of the adjustable liner therein after which the mold wheelmay be rotated to return theniold to the normal ejecting position.

After the desired mold change has been made, the operating lever 42 is swung rearwardly or allowed toswingrearwardly un der the action of the tension spring 82, the

shaft 23 then moving forwardly. The ini tial part of the forward movement of the shaft 23 causes the arm 36 carried by it to also move forwardly, thereby causing the upward extension 58 on this arm to move for is of the greatest length, so that the lowwardly from the pin 59 and also causing the roller 136 to move from aposition beneath the cam face 137 on the bracket 49,in consequence we of which the selector finger 53 will move forwardly under the tension of the spring 54 and the bracket 49 will swing downwardly by gravity about its pivot 50, thus moving the feeler finger 68 forwardly into the recess 67in the rear'edge of the adjust able liner 66 of the mold which is then in ejecting position, and causing the feeler linger 68 to descend until it comes to rest on the shoulder or inner end 167 of the mold liner, as shown in Fig. 4. Duringthis part of the forward movement of the arm 68, the lug 34 -will-have a lost motion 1n the aperture in the arm 36, the forward edge of this aperture advancing from a position in contact with this lug as shown in Fig. 1 to a position removed forwardly therefrom as shown in Fig. 4. The length of the recess 67 in the mold liner 66 determines the extent of down-- ward swing of the selector finger 53' and bracket 49. For example, the liner-66 shown in 4 is of the shortest length so that the mold slot will be of greatest length, requiring the widest ejector blade, and the recess or end of the gravity pawl 62 depending from the selector finger 53 will descend to a position opposite to the lowest and foremost step 61on the forwardextension 60 of the arm 36. In this case, as the forward movement of the arm 36 continues, the pawl 62, the lower end of which is engaged with the lowermost and foremost step 61, will be roclzedabout the stop screw 64 as a fulcrum, causing its upper end to swing rearwardly and actlng through its pivot 63 to shift the selector finger 53 rearwardly, against the action of the spring 54, until the pin 56 stops against-the rear end of the slot 57 in the bracket 49, the feeler finger 68 being then withdrawn rearwardly from the recess 67 in the mold liner 66 as shown in Fig. 5 and the forward advance of the arm 36 being arrested at the moment the rear edge of the aper ure 65 in the arm 36 contacts with the lug 34. Since the lug 34 is thus not shifted to conform with the 'of the mold liner so forwardly, the eject-or blade box 31 will remainat the extreme lateral positionwhich presents the widest e ector blade 30 therein .in register with the master blade :28, it becoming attached thereto by the engageni ,i i of the extension 29 of the master blade with the correspondingly shaped recess in the rear edge of such ejector blade. During the initial part of the forward mo shaft 23 under the tension of g and while the arm 36 is moving idly with respect to the lug 34 from the position shown in Fig. 1 tothat shown in 4, the bolt 72 descends. out of locking engagement with the master blade 28, the contact screw 74- then riding downwardly to the lower cam face (3i, and the forward movement ofthe shaft 23 re-loclrs the pinion 7 tovits driving shaft. 8, either during the early por ion of the for ward movement of said shaft by the retraclion of the set screw. 21 from the lever 20 in Figs; 1 to 8, inclusive, or by turning of the pinion 7 to bring the recess 11 therein into register with the pin 9 in the construction shown in Figs. 9 and 10. Since an e ector blade of proper width for the mold in operative position has been thus brought into position to be operated by the maste blade28, the machine may be started 1 pulling forward the usual starting handle If the adjustable mold liner 66in the mold brought into operative position is relatively longer than in the exam ale describe' ing a relatively shorter slot ca ity in the mold'and requiringa vielatiwaly narrower ejector blade, the operation is the sameas above described with exception that the relatively shorter recess 67 in the rear edge of such longer mold liner will arrest the downwardswing of the braclie; 49'

and the selector finger at a. relatively high er level so that the lower end of the pawl will be opposite to one of the intermediate without obstruction I hereby.

In bringing a mold into use which has an ad ustable liner 66 of maximum length forming a slot 1n the mold of minnnum length and the oblique ribs ch -e or its parts and requiring the use of the narrowest ejector blade, it will be understood that the recess in the rear edge of such liner will be of-minimum length it will arrest the downward swing of the selector finger 53 at the highest level so that the lower end of the pawl will be engaged by the uppermost and rear most step 51 and hence the arm 36 will be permitmd to move forwardly to its maximum or full iitent, moving the lug 3% forwardly a corresponding distance and thereby shifting the ejector blade box 31 lateral y LO its extreme position where the narrowest e ector blade 50 registers with the master blade 28, as shownin Fig. 8. By graduating the steps 61 and the recesses 67 in the rear edges of the adjustable mold linersto conform with the varying widths of the ejector blades in the ejector blade box, it will be understood that an e ector blade of the proper width is brought of the slot or casting cavity in the mold in operative position.

' Since the bringing of another mold already on the mold Wheel into operative or active position, or the removal of a mold from the mold wheel and substitution of another mold or the changing of the adjustable liner of a mold on the mold wheel all require rotation of the mold wheel to remove the mold previ ously in use from its normal vertical position e ecting mechamsm, and such in front of the v rotation of the mold wheel. cannot take place until after the mold wheel turning pinion has been unlocked o unclutchcd from its operating shaft, which latter oper; .ion does not talre place until the operating lever has been operated or drawn forwardly to substantially its full extent, and such full operation of the operating lever insures proper and complete operation of the ejectorblade selecting mechanism, the selection of an ejector blade of proper width to conform with the length of the slotin the mold brought into use is always insured. The control of the starting handle of the machine bythe ejector blade selecting mechanism prevents starting of the machine while the operating lever for t 196]. ector selecting mechanism is pulled. forwardly from its normal operative result from the use of an ejector bladeof improper width to conform with the length auto- .matically into use to conform with the length rotatable in. d

of the slot or casting cavity in the mold wheneve'ra different mold is brought into use or a change is otherwise made in the length of the mold slot, but also provides means for automatically selecting and bringing an ejector blade of the proper width into'operative position whenever a change is madein the length ofthe mold slot in whichthe slugs are to be cast, thereby greatly ass1sting the operator and saving time in setting the machine to opcrate with a mold of changed length.
