LINE-CASTING mAonniE.

Be it -known that I, Jens R. ROGERS, of the borough of Brooklyn, county of Kings,

and .State of New York, have invented anew and useful Improvement in Line-Castg Machines, of which the following is a specification.

This invention hasreference to line'castng machmes of the general organization represented in Letters Patent of the United States No. 436,532, wherein type matrices, assembled temporarily in line, are-suspended in adeVlCe-lUKMYIi as the first elevatoijand lou'eredthereby-to a position in .front ofa horizontally slotted mold. whh his thereafteradvanced facewise against the ii ati'ices,*wh'ieh close'thet'ront of the mold,

while it-is filled from the-rear with molten "-metal to'producea-slng, or linotype, on the Q formed by. the matrices. The characters I stand in unfinverted position in the matrices, and heretofore it has been the practice to have characters of different sizes, as' ,nonpareil,' minion, etc.,'aline at the top of front edge of which the type characters are the characters; in other words, matrices of all fontsjhad a common alii ing level in the machine, at the heads' or topsof the characters.

Under a "new system recentlyinaugurated,

matricesof various sizes are arranged 'to have a'coinmon alinement at the base of the characters; or in other words, matrices used in the machine for fonts of ditferent'sizes have their characters arranged to aline at the base at one and the same level. .When the older matrices are used, with the top alinement, the elevator descends always to one and the same level in presenting the matrices before the mold, but if matrices using the base aline'ment are employed, the

elevator is required to descend to a different distance in order to properly present the 1 matrices in relation to the m'old, and this distance must be 'varied to somev extent, ac-

cording to the size of the characters em-v ployed and the thickness of the slugs which 'the mold is adjustedto produce.

F ig. 6 is a top plan view of pa rtsshown in the preceding figure. Fig. '7 is a perspective view of themold and the attached arm to limit the descent of the elevate and the contained matrix line. Fig. 8 is'a vertical section through one end ofithe first elevator, and the adjacent. partsfillustrating the manner in which its '(iescent'is arrested. Figs. 9 and 10 are news illustrating thealinenient ol matrix characters at the head and foot rcspcctivcly.

Referring to the drznvn'igs, represents the upright mold wheel, carrying one or with the matrix characters opposite the.

mold slot, as shown' in Fig. 1.- While the matrices are in this position, the mold is advanced facewise and crowded tightly against the matrices, and held in this position while the mold is filled from the back with molten metal, ejected from the mouthof the usual melting pot, not shown in the drawings. 1

v For the purpose .of throwing the main clutch, which drivesthemachine, out of action ifthe matrix line is not lowered to the properoint, a rod, a, is provided, its up er end eing guided in the main-frame an its lower end sustained by a spring, a,

so that it may swine forward and backward. The lower end of this rod (1 bears against .one end' of a centrallylpivoted lever, a, which acts-at the opposlte end against a bar, a", acting to throw the main clutch out of operation. The rod a" is provided w th a lip, a", and receives its motion to operate the clutch from a Horizontal slide, a, mounted in the main-frame in position to. be acted upon and; .pushed forward by the mold disk 0 as the mold is advanced against the matrices.

So far as described, the parts referred to correspond to the parts indicated by like letters in Letters Patent No. 436,532, and have a similar mode of action. In the former patent, the rod a? stood-normally in its uppermost position, with the lip a in position to beengagcd by the actuating slide, a. The first elevator, N, in descending acted on the upper end of the rod to push it downward, and if the elevator and matrices descend to. the proper (level the lip a was carried below the slide, which ad vanccd thereovcr without affecting therod-d or ing the lip the clutch. If, however, the elevatorfailed to descend with the matrix line to the proper level, the lip a stood in the path of the slide a, which latter acted tupush ro'd of horizontally, and' then-b)! khrvw the clutch out of action, is before nn-litionod.

Tlle present strut-lure'dillr-rs from that of the patent. among other things. in harslnn'l normally above the an:- tuating slide 4*.

erative position by a horizontal lever, B,

centrally pivoted to ,thetop of the vise .frame portion Act the main frame, with ,oneend standing normally over the upper end of the rod a, to hold the same down in its active position, as shown b full lines in Fig. 3. The opposite end 0 the lever B.

carries a stud, b whichis acted upon by the eccentric end of an arm, I), carried on a vertical rock shaft, b, which is seated in the first elevator, and provided at its lowerend with a second arm, I), acted upon by an arm, 0, secured to the mold or molddisk.

T he arm 6 rises and falls with the first elevator. If the elevatorv descends with the matrix line to the proper level, the arm b is presented opposite the lip c on the upper end of the plate C, so that when the mold advancps toward the matrices, carrying with it the plate C, the lip 0 of the latter will act onthe arm b,-causing the endof the arm I) to actuate the lever B and'swin its' opposite end from over the rod a, w ich latter will be lifted by the spring .a'until' the lip a" stands above the path of the slide a,-thus permitting the rod a" -to remain idle when the mold advances to the matrices, so that the main clutch may remain inaction. In other words, the plate 0, advanc ing with the mold, permits the rod 'a" to assume such position that it will not disengage the main drivingclutch. If, however,

the elevator fails to descend to the proper level with the matrices, the-arm b wlll stop I in its descent above the plate C, and"when the mold advancjcs, the plate C will pass.

under the 'arm 5 without 'afiecting the same; and consequently the leverB will continue to hold the-,fod a down in such positicn' that its lip la will stand in the path of the slide a, hnd therefore the advanc-,

ing mold-wheel, swinglng rod 0." before it, will cause'the r'dd to actuate the lever a and bar a, and thereby throw the clutch out of action, so that the machine will come to a rest.

After the rod a has been permitted to rise, it must. be again depressed until its upper end is below the level of the locking lever B. This is efi'ected by anangular lover, I), centrally pivoted to the main frame, with one end in position to act on a projection on the side of the'rod a, and its other end,7containing a roller, in position to be acted upon by a cam surface, e, on the vertical ni'lll of the first elevator, N.

'Whcnthe elevator rises to lift the line from horizontal casting position, and againgwhen in a vertical position opposlte the ejector' which delivers the slug therefrom.

llv is held down in its op- I it son'lclimcs happens that the mold disk is provided with two, three or more molds, and when the disk advai'ices toward the matrices with a mold in the ejecting posi* tion, there would be danger of a bottom mold actuating the slide a and stopping the machine at an improper time. The lever 1-) also prevents this action, since it carries the lip (625 below the'slide a at such time.

hen the first elevator N descends with the matrix line, its downward movement is arrested to detern'iine the exact level of the line by a block, F, Fi 1, 2 and 8, attached to the elevator N am arranged to bank on top of the plate (1. in other words, the descent of the elevator and the matrices is limited by the contact of a member on the first elevator with a member attached to or forming part of the mold.

By adji'lsting the plate C vertically in relation to the mold, or by replacing it with a plate terminating at a different level, the descent of the elevator and theanatrices may be varied at will, as the size of the characters in the matrices, their location therein, the sipe ot' the mold, or other conditions may demand, and thus the machine may be.

adapted to use matrices with either the head or the foot aline'ment.

I believe it to be wholly new in the art to limit the descent of the matrices through devices acting directly" on the mold or a part in fixed relation thereto, and I believe it to be wholly new to utilize a part attached to and forming part of the mold for the purpose oi thrmving the main driving clutch out; of action and arresting the movement of the machine.

The molds are commonly constructed, as shown in Figs. 1 and 7, with a so-alled keeperplate, 0 secured firmly thereto and grooved to engage the lower ears of the matrices, for the purpose of securing the alinement of the matrix characters with the mold slot. The keeper-plates are sometimes adjustable vertically in relation to the mold slot, as in Patent No. 846,053, and in such case the adjusti-ncnt oi the keeper willctlect the corresponding adjustment of the plate 0. I prefer to attach the stop arm C to this keeper, as shown in Fig. 7 but it may be formed upon the keeper, or on the body of the mold, or attached to the mold disk, the only requirement being that it shall be held rigidly at a definite height; that is to say, in a definite relation to the mold slot, the, banking of the matrix carrier N upon this member being emlivalcnt to its banking directly upon the mold. This permits a great, accuracy of adjustment, and in sures the presentation of the matrices'in proper relation tothe mold slot with much greater certainty than by the mechanisms heretofore in use, in which the descent of the line was controlled by devices distinct from the mold and from the line carrier.
