CORPORATION OF NEWJERSEYQ LASTING-MACHINE.

To all whom it may concern Be it knownthat We, ARTHUR BA'rns and,

ROBERT H. SILvnsTEmsubjects of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements inLasting-Machines, of which the followingdescription, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts ,inthe several fig ures.

This invention relates to lasting machines,

and more particularly to that type of lasting machine which is adapted to work on.

the speed at which the machine isintended to operate is ordinarily the same for all p01 tions of the Work, notwithstanding the fact that the operator can successively present. to the lasting devices certain parts of the upper more rapidly thanhe can present other parts thereto, during the progress 01 the ork; and as themachine is necessarily limited to run at that speed which is required to enable the operator to last properly those parts. of the upper which require the greatest amount of care it will be seen that on other parts of the upper, where he might move the shoe along and last 1t more.

rapidly, the machine is not operating to the best advantage, and hence some of the *op erators time is Wasted. ,Ithas been found yin practice that witlrsonie grades of work there are advantages which follow from increasing the speed ofa lasting machine of the class referred to at certain portions of the shoe, as for instance along the sides and at the heel, or at either of said places, and decreasing such speed at other portions, as

Such advantages,

for instance, at the toe.

are particularly noticeable in, lasting shoes which are made of inferior or weak stock as for example shoesof felt, carpet,sheepskin, or the like where the operation of the pincers could be suspended when working Specification of Letters Patent. 1

along the sides of the shoe, and the stock lasted 1n bythe p resser or wiper, the speed otthe machine being increased at this point in the operation and the lasting being there:

by caused to proceed more, rapidly until other portions of the shoe were reached at whichit would be desirable to again dc By such procedure, a .conslderable saving in time would be effected, and the daily output of the machine correspondingly increased. It is an object of the present invention. to lmprove lasting machines of this type by securing :therein the results referred to, and

toth1s enda feature of the invention comprises theprovision in a lastingo-r like machine adaptedtqwork on different. parts of the upper successively, of speed-controlling means constructed and arrangedto' enable different parts ofthe upper to be lasted at By the provision of such means the operator canso :vary the speedof different speeds.

the machine that each, portion of the shoe as is presented to the lasting instrumen tahtles can be operatedfupon as "rapidly as is consistent with the work to be done on that portion of the shoe and 'with the ma nipulations required of the lasting devices,

The lasting devices of this type of machine include pincers which are actuated togrip each portion of thefuppersuccessively and pull it upward, and to then lay it overandf upon the last. Heretofore, for lasting Welt M ed Work, the machine has been providedwith means for suspendingthe operation of the overdrawof the pincers when the heel portion. of the shoe isbeing lasted and at the same time for actuatingthe tack-supplying mechanism so as to cause it to deliver shorter tacks than those supplied by it :for

other portionsof the shoe. Such a construction, however,-cannot be employed in McKay work, for in this type ofshoe although it-is usual to suspend the action of the pincers at certain portions, such as at the side of theshoe, the required length of tack is notfto be determined solely by the part otjthe slioefinto which it is to be driven, but rather by the thickness of the upper Ina-l ments, of provision for using less than the,

terials which it is to secure, it being understood that the thickness of the material to be secured varies at different parts of the shoe owing to the presence at some places of bunches, or plaits.

Accordingly, the invention comprises also the provision, for a lasting or like machine adapted to work on different parts of an upper successively, of means for throwing the pincer mechanism out of operation While certain portions of the shoe are being lasted without affecting the operation of the tacksupplying mechanism.

Another broad feature of this invention is found in the combination with means comprising a plurality of working devices as,

for example, a pincer and a tacker, or a Working device having a plurality of movements as for example a pincer which has updrawing, overdrawing and plaiting movewhole number of devices. or movements and provision for changing the speed at which the device or devices are operated. In the illustrated embodiment of this feature of the invention provision exists for imparting to the lasting pincer at times a plaiting movement in addition to the closing, updrawing and overdrawing movements and according to the new characteristic provision is made for changing the speed at which the machine is run so that a slower speed may be maintained when the larger number of movements are used and a higher speed when the smaller number of movements are being made by the pincer. This change in speed is made, as herein, shown, by means.

additional to that heretofore used to start and stop the plaiting movements, the arrangement being such that while a suitable speed for lasting'the toe is maintained the plaiting movements may be, started and stopped as usual, but when the higher speed, which is adapted for use inlasting and tacking the heel seat, is used, the mechanism for producing the plaiting movements is automatically thrown out of operative ,connec' tion with the driving shaft.

An advantage of practical consequence following from the use of the described pincer stopping mechanism is in the fact that the entire plaiting mechanism is rendered inactive, including the oscillating rocker which hasheretofore been continuously in motion whenever the machine was running. It will be readily understood that the entire elimination of the reciprocatory or oscillatory motion of the plaiter lever and rocker back and forthreduces materially the vibration of the machine, and it is important that this be done during the time when the overdrawing movements of the pincers,

whereby the pincers are rendered practically inoperative, and according to the new feature provision is made for increasing the speed of the machine when the pincer is thrown out of operation and the tacker remains in operation, and decreasing the speed again when both devices become operative.

This change in speed is made simultaneously .morecomplex organization in operation for producing additional movements it is,rea-' sonable to allow greatertime for each cycle of the machine. Of course the speed of the described lasting machine mustalso be governed, as above fully pointed out, in accordance with the difliculties incident to the proper presentationby the operator of the different portions of the shoe to the working tools, the toeportion which is to be plaited usually requiring more care than the sides and the heel portion which is not ordinarily seized by the pincers permitting the most rapid presentation of the shoe.

Conveniently the speed-controlling means aforesaid and the pincer-controlling means are operatively connected as has been suggested so that when the speed of the machinehas been accelerated to suit the requirements of the work at those portions of the shoe that can be quickly lasted, the pincers shall be thrown out of operation. It is, however, within the contemplation of the invention to operate the speed-controlling means and the pincer-controlling means referred to, independently, one of the other.

These and other features of the invention, including the speed changing mechanism and certain details of construction and combinations of parts, will now be described in 115 connection with a preferred construction applied to a machine of the type referred to in the aforesaid Letters Patent, but it is to be understood that the invention is not to be considered as limited in its application 120 to this type of machine nor to the particular construction which is shown and described. herein by way of example.

Referring to the accompanying drawings,

in which the same reference characters defast pulley 10 and the friction disk 12 is an section showing the parts in a difierent position; Fig, 4: is an elevation of a portion of the base of the machine, somewhat en larged, showing a variable speed mechagIllSIIl; Fig. 5 isa section on the line l4,

other pulley 16 which is provided on its side adjacent the friction disk 12 :with a similar friction disk 1+1 which may be integral with said pulley orsuitably securedthereto, As is hereinafter described there 1s located between the adjacent faces of the friction disks 12 1 1-, a variable speed device. The loose pulley 16 is connected by a belt (not shown) with another pulley 1S loose upon the main driving shaft6 in the head of the machine,

and a one position stop and start driving clutch controlled by a pedal lever 13 pivoted in the baseof the column 2 is adapted to con-j 'nect the pulley 18 with] the main drlvmg shaft 6, and also to disconnect it therefrom. The connections betweenthe one stopping position clutch and the pedal leverlES comprise a vertical rod 20 pivotedat its lower end at 22 to an, extension 24 from the pedal lever 13 its upper end being-suitably connected with the clutch. The rod 20 also is coupled to -a brake shoe 26;which is brought intoc ontact with the pulley 18 when the clutch is actuated to disconnect said pulley from the shaft 6, but as these parts form no part of the present invention further description will be unnecessary herein.

The vari able speed device, which as aforesaid is located between the friction disks 12, 1 1, on the counter-shaft 8compr1ses a pan of idle friction wheels 28 whichbear against a the adjacent faces of the friction disks 12, 14, as shown inFigs. 4 and 6, one wheel on each side of the counter-shaft 8. Each of these friction wheels is rigidly secured to a short shaft 30 (see Fig. 5) journaled inthe arms 31, 32, of a yoke 3& which is mounted upon the upper end of a vertical shaft 36 journaled in a bearing or bracket 38 and capable of turning thereinfor a purpose to be hereinafter described. I Eachof the arms 32 of the yokes isprovided with a bearing 40 in which is; mounted a short vertical spindle 42the two parts so and 4L2 forming a telescopic coupling. On the lower end of,

each of the spindles 42 another bearing 14 is mounted so as to be capable of sliding ona pin 16 which is journaled in it. This pin has its axis at right angles to that 10f the spindle 12 as is clearly shown in Fig. 5.

Each of the pins 16is attached to onearm 4:3 of a frame lever 50, other arms 52 of said a lever being pivotally mounted at 54; upon the bracket 38. Apin 56 located in a slot 58 in the lower end of the vertical rod 20 forms a i lost motion connection between the pedal p or lever 13 and the frame lever for a purpose to be hereinafter set forth. The pin 1 56 has springs 60 suitably connected to it which are secured to a rod 62 in the base of the machine, said springs servlngto .maiutain, through the connections tlbOWB de scribed, the friction wheels 28 intheir normal positions. i

It will be clearly seen from the drawings that as the frame lever 50 is rocked about its pivot pins 54 it will, through the pins 16 and telescopic connections 40, 42, tend to vary the angular position of its friction wheels 28 in relation to the friction disks 12, 14, see Fig.;6, and consequently vary the speed of the machine.

The arrangement is such that, through the connections above described, movement of the yokes 34L aforesaid will tlp the axis of rotation of each of the frictionwheels 2S to the*san1e extent but in opposite directions. 1 Thus the paths of contact of :eachfriction wheel with the friction disks 12, 14, will be shifted nearer to or farther from the periphit cry of the frictiondisk-12 and at the same time farther from or nearer to, respectively, a

the periphery of the friction disk 14 on the loose pulley 16; and as the disk 12 which is rigidly securedto the shaft 8 rotates at a constant speed it will be evident that the a speed of the loosepulley 16 will depend upon the angular positions into which the friction wheels 28 are ad usted by the operator. In order that the two friction disks 12, 1

14:, may be maintained at substantially the same distance apart irrespective of theangu lar positions of the friction wheels, the

periphery of each wheel has a shape corresponding to that of an equatorial zone of a sphere (see Fig. 6) :and the adjacent faces of the friction disk 12, respondingly.

To exert the necessary pressure between the friction disks 12, 1 1, and the friction wheelsp28 sons to start the pulley 16 in motion the machine as herein shown is pro- 14, are recessed corvi ded with a wedge-shaped member 641 (see Fig. 4) that is adapted, when the operator depresses the pedal 13 to be forced against a similar wedge-shaped surface upon a collar 66 loosely mounted upon the shaft 8 and I prevented from movement :lengthwise of sald shaft m one ,ClII'GCf/IOH by means of a fixed collar 68 and in the other direction by the wedge-sl1aped member 64. A thrust col lar with ball bearings 70 may be interposed between the two collars to lessen thefricti'on between said parts. The opposite face of the wedge-shaped member 6a abuts against the boss 72 of the loose pulley 16, a collar similar to and performing the same function as the collar 70 being interposed between the boss 72 and the said face.

31 toggle joint 74, 76, aivotally connects the extension 78, of the pedal 13 with the lower end of the wedge-shaped member 64 and a spring 80 tends to maintain the toggle in its normal or straightened condition, the extent to which the toggle is straightened being preferably determined by a lug 82 of the member 74: contacting with a lug 8 1 of the member 76 as shownin Fig. t. If desired, one of said lugs could be provided with an adjusting screw made to engage the other lug so that the extent to which the toggle is straightened could be varied. The

spring 80 also serves to maintain the wedgeshaped member 61 in the operative position whil the operator is working the pedal 13 to vary the speed of the machine.

The lugs 82, 84:, are so arranged that the toggle 7 1, 76, is bent slightly and when the friction disks 12, 14, are forced by movement of the wedge-shaped member 64: into engagementwith the'friction wheels 28 the toggle will break, thus'permitting the pedal lever 13 to be depressed farther to alter the speed of the loose pulley 16 by adjustment of the angular position of the friction wheels 28. In this connection it will be noted that the breaking of the'toggle 74, 76, indicates to the operator that a further depression of the pedal 13 will vary the speed of the machine.

To enable the pedal to be depressed for raisin the brake 26 and setting the wedge 64; to start the machine and cause it to run without affecting the speed changing mechanism, there is provided a lost motion connection, 56, 58, (see Fig. 5) as hereinbefore mentioned in the chain of connections between the friction WmEQlS 28 and the foot pedal 13. Alternatively to the wedge arrangement for throwing the friction gear into operation, the yokes 34 carrying the friction wheels, when the pedal 13 is released, may be moved by any suitable arrangement through an angle on their pivots sufficiently great to shift the peripheries of the friction wheels beyond or away from the recessed portions of the driving and driven friction disks with which they'normally engage. will shift the wheels first into engagement with the friction disks and then vary the speed or the ratio of the gear. When this method of throwing the friction gear into actionls utilized, the driving and driven Conversely, depression of the pedal friction disks are preferably given a limited amount of play axially, and a suitable spring or yielding thrust bearing or device is preferably provided that holds them yieldingly toward each other and causes the necessary friction between them and the friction wheels. Furthermore the friction faces of the disks may be so shaped, at the portions where the friction wheels first engage, as to form a slight angle with the direction of through spring 134 to the cam 135, Figs. 1

and 7. The pincers are closed by the down ward movementof a rod 136 effected by an arm 137 of a rock shaft 138 the other arm 139 of which rests on the periphery of a.

cam block 86. This cam block has a track in its front side'from which is actuated a lever, not shown, here to oscillate a sleeve shaft 140 and rocker 14.2 to give plaiting movements to the pincers when set to do so by the bell crank 143 and knee lever 1t5 all as fully explained in said patent from which it will be learned that the plaiting movements are started and stopped by manipulation of the knee lever additional to the other, normal, movements of the pincers. The pincers are also moved outwardly from the machine, see dotted lines Fig. 7 to produce the overdraw by means of a spring-operated thrust rod 88 of which the movements are controlled by a face formed on the rear side of the cam block and engaging a roll 87 on the pincer thrust rod. In the preferred construction herein described-means are provided for suspending the operation of the pincer by disconnecting the cam 86 from which are derived the 'pin cer closing,overdrawing and plaiting movements. While the plaiting movement of the pincers is susceptible of independent control by the knee lever 1 15 that movement, with the overdrawing and closing movements, is started and stopped by the cam 86 while the updraw movement as herein shown is continuous at all times.

In a contemplated use of the machine the machine will be run at its starting or minimum speed while the toe portion of the upper is being lasted over and 'plaited into place upon the shoe bottom. Then the toe of the shoe has been completed the plaiting mechanism is thrown out of operation by the knee lever1-l5 and when the sides are reached, or before if desired, the speed may be increased to the maximum at which the the pincer and the tackera lVhen the heel' portion of the shoe ishreached whereno including the gripper updrawing cam and the tucker operating cams. By this arrangement one of the working movements which can be imparted to the pincers, that is, the plaiting movement, can be suspended and resumed at the will of the operator and,

at the option of the operator, the speed in creased at which the remaining movements are effected. Also the pincers can be thrown wholly out of operation and the speed of another working device, which is the tacker,

and of the entire actuating mechanism of the machine will be automatically increased.

To provide for such uses. of the machine in which the invention. is illustrated, and other uses which may be found desirable, the cam 86 is connected to the shaft 6 of the machine by a clutchwhich is controlled from the pedal 13 by means of the vertical rod 20 to which is adjustably and detachably connected by a clamping screw 91 a rod (see Fig. 1) that is in turn connected to a lever 9:2 pivoted at 94 upon. the head of the machine. The free end of this lever has a cam face 96 upon it, which on depression of the pedal 13 is adapted to be forced into contact with a plunger 98 arranged to have a slidingmovement limited by means of a pin and slot connection 97.]

99, ina bearing 100 arranged in the head of he machine. end abuts against a shoulder 10 1 Ion the inside of the bearing 100 and the other end against a collarlon the plunger 98 (see Fig. 1),maintains the said plunger always in contact with. the end of the lever 92. Connected to the forward end of the plunger 98 is a rod 106 that is coupled to a lever 108 that forms partof the clutchoperating mechanism, hereinafter described,

which renders the overdraw movement of the pincers inoperativeqwhile the side or heel portions of the shoe are, being lasted. The cam 86 is loosely mounted uponthe A. spring 102, of which one i above referred to.

that when the projection 114 is disengaged from the recess the cam 86 will be disconnected from the shaftG and maybe arrested to stop the grippers in a predetermined position 'as hereinafter described. h

The means for causing the pawl 110 to be disengaged from the recess in the collar 117 comprises the lever 108 above mentioned which is pivoted "at 109 upon a pin that ex-. 1

tends transversely of the machine. The lever is provided at its upper end witha wedge-shaped portion120 shown by dotted lines in Figs. 2 and 3. This wedge-shaped portion is adapted, when it is desired to suspend the overdraw movement of the pincers, to heintroduced from the front by movement of the lever 108 into a position in which it will engage a projection 121 of the pawl1l0 during the next rotationof thecam to withdraw the pawl from the recess 118 in the collar 117. After the pawl has been disconnected from the collar 117, further rotation of the cam 86 is prevented by the projection 121 coming into contact with a portion 122 on the upper end of the lever 108. i

The rod 106 that connects the ,lever 108 with the plunger 98 is provided'with a pin and "slot connectionlQat, and aspring 126 is interposed between theend of the rod 106 and the bottomof a socket in the plunger 98.

In the event of the operator, throughthe connections described, moving the lever 108 at a time when thepawl 110 has just passed the position in whichit is capable of being withdrawn from the recess inthe collar 117, this pin andslot connection will permit the lever 108to pause until the pawl has moved from engagement with it whereupon the spring 126, whichwill have been compressed by jthe action: of the operator, will expand and complete the movement of the lever 108 1 into the position in which it is in readiness to withdraw collar 117. l h l q It will be understoodthat,mechanism the pawl from the recess in the v such as herein: described, or any equivalent inechanlsm, for suspending the operation of the pincers does not affect the operation of the thick presser or wiper device 1 18jdescribed and shown in the Letters Patent When the pincers are thrown out of operation on those portions of a shoe where the operator finds it to be undesirable to pull the upper, therefore, the lasting operation is performed by the thick presscr which pushes the upstanding upper over upon the innersole, to which it is socured by the tacks or other fastenings as the worlrprogresses. p y l Theoperation of the machineis asfollows:-The parts bein in the position shown in Figs. J1 and the operator depresses the pedal 13 thus raising the rod 20 and removing the brakeshoe 26 from the pulley 18 and by means of the wedge-shaped portion 6a forcing the friction disks 12, 14, into contact with the friction Wheels 28, so that the machine is started. When the operator desires to increase the speed of the machinehe depresses the pedal .18 further and this causes the lower wall of the slot in the rod 20 to engage and lift the pin 56 and move the frame lever 50 about its pivots 54:. This movement of the frame lever through the telescopic connections hereinbefore described will alter the angular position of the friction wheels 28 in relation to the friction disks12, 1 1, and thus vary the speed. of the machine. When the heel or other portion of the shoe is to be lasted without the use of the pincers the operator still further depresses the pedal 13 and this, through the rod 20, brings the cam face 96 on the lever intocontact with the plunger 98 thereby moving the rod 106 and the lever 108 toward the left in Fig. 1 so that the projection 11 1 of the pawl 110 will be brought by the rotation of the cam 86 (in the direction indicated by the arrow in Figs. 2 and 3) into engage ment with the wedge-shaped part 120 on the lever 108 and be withdrawn from the recess 118. The cam 86 is now disconnected from the shaft 6 and is brought to rest by the en gagement of the part 122 on the lever 108 with the projection 121 on the pawl 110, thus suspending the overdraw movement of the pincers.

At any time in the toe or side lasting operation the workman can force down the pedal to cause the tacker to wipe the upper over and insert a plurality of tacks in rapid succession without the use of the pincers. This is particularly desirable in lasting the sides of the shoe where it often occurs that a plurality of operations of the wiper and tacker to each pulling operation of pincers can be employed advantageously. By adjustment of the connection 91 the time at which the throwout will occur can be changed with relation to theprogressive increase of the speed which is effected by the depression of pedal 13. If it sho-uldbe desired to employ the high speed with the pincers in operation the clamp 91 can be loosened to disconnect the clutch from the pedal 13. tomary to fasten the plaited toe portion of the upper by a binding wire and in this work the tack inserting operation is not 5 needed. By an obvious extension of this in vention a throwout clutch be connected with an element of the tacker actuating mechanism, as for example the cam 150 which operates the tack block 1 17 and associated devices through the lever 152 and slide 154, to discontinue the upper fastening operation by tacks while the slow speed employed for plalting is 111 use and toresume the tacking operation automatically when the higher speed suited for side lasting is In making welt shoes it is cusattained. Obviously the plaiting mechanism I may also be controlled with the speed changing control by a connection from the rod 144 or the like to the pedal rod 20 instead of being controlled by the separate knee lever as in the prior patent mentioned.

Instead of the mechanism herein shown and described by way of example for suspending the operation of the pincers any other suitable means for producing this result may be employed. As shown in Fig. 7 for example, the roll 87 on the pincer thrustrod 88 that is operated by the cam 86 in stead of being mounted directly upon the thrust rod could be carried upon a sleeve on the rod, and there may be provided a detent 1.60 pivoted upon a block secured to the rod and adapted to engage the sleeve. XV hen the detent is engaged with the sleeve the pincer thrust rod will be actuated by the cooperation of its spring and the cam 86 to effect the overdraw of the upper but when the detent is disengaged from the sleeve by mechanism hereinafter described the spring ofthe thrust rod will move the rod forward and hold the pincers out of engagement with the upper. At this time a light spring 162 keeps the roll in engagement with the cam and the said sleeve is moved idly upon the thrust rod so that the detent when released to reengage the sleeve shall reengage it at the proper time in the cycle of operations of the machine. The mechanism for disengaging the detent from the sleeve on the thrust rod may comprise the rod 90 and the clamp 91 that is adjustably mounted on the rod 20 which couples the pedal lever 13 with the clutch for the pulley on the main driving shaft. By this arrangement when the operator depresses the pedal lever the extent that is necessary to give the speed that is desirable for the lasting of a portion of the shoe which does tent 160 will be disengaged from the sleeve on the thrust rod by the connections -,described and the operation of the pincers will be suspended.

It is obvious that instead of the mech-, anisms herein shown and described for suspending the operation of the pincers when the speed is changed any other suitable mechanism for producing this result may be employed, for example the cam that produces the updraw movement of the pincers may be provided with devices such for example 11131/03' and connected with the speed changing mechanism for disconnecting the cam from the main driving shaft of the machine or both the updraw cam and the overdraw cam may be provided with such devices. Moreover in place of the particular construction herein set forth any other suitable speed-controlling means may-be emas shown in British Patent No.

ployed for varying the speed of operations of the machine such for example as that shown in Fig. 7, and in a broad aspect of this invention the speed-controlling and pincer-controlling means might be entirely independent so that each may be operated without affecting the other;

In the construction of speed controlling means. shown in Fig. 7, approximately spherical faced idle friction wheels 164, 166 corresponding to the friction wheels28 o the first construct-ion, instead of bearing against separate frictioniydisks, are interposed between thefixed pulley 10 and the loose pulley 1.6 and bear respectively against adjacent annulanflanges or rims 168, 170

on the said pulleyslO and 16. The wheels 164, 166 have aperipheralcontour substan' tially like that of the wheels 28 of the first construction and the flanges or rims 168,

extensions of the frames176, 178, the variaa tion in the paths of contact of the wheels 16 1-, 166 with the flanges168, 170 being indicated by and along the linesofthe broken line arcs 179. Turning; movement of the crank arms 180, operating through the rocker frames 176 178,110 change 'the angular plane of the idle friction wheels 164, 166 and thus to vary the paths of contact of each of said wheels 164, 166 with the flanges 168, 170 on the pulleys 10 and 16, operates to impart varying speeds to the loose pulley 16 from :the constant speed pulley. 10 and thus to vary the speed of the machine in substantiallythe same manner as in the first construction. For operating the crank arms 180.the said crank arms are connected by links 182, 184 to an arm full extent until after .the pedal 13 has been depressed sufficiently to start the machine. Tl'iereafter further depression of the said pedal operates tl'irough the connecting rods 182, 184 and crank arms 180 to move the friction wheel carrying rocker frames 176, 178 so asto turn the friction wheels 164, 166 to accelerate gradually the speed of the machine. The wedge 64 of the first construction is employed to put upon thepulley 16 the pressure required to render the friction wheels 164, 166 eiiective and a spring 192,.

operating substantially like the spring 80.

of the first construction, serves tokeep the I wedge 64 in operative position while the operator is manipulating the pedal 13 to vary the speed of themachineL Having describedour invention what we claim as new and desire to secure by Letters Patent of the United States is:

1.
