To all whom it may concern: j .Y

Be it known that I, HENRY F. BECHMAN, of Battle Creek, inthe county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Steraoty e- Plate-Casting Ap aratus; and I' hereby (Pieclare that the f'ollbwing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which :formem cation.

his invention -is an improvement in apparotary printing` cylinders, and the object of' the invention is to provide a duplex casting the other, 'and' vice versa.'

other late may be4 made ready for4 cast-ing, and whi le the r'st plate is being removedfrom its casting box, anothercanfbeicast in the otherbox, the making ready of one 'ilask taking place during the castinIgo eration in invention the copes o f the twoiasks are so dling the copes and facilitating the o eration.

of making the plates. Means are a so provlded whereby the copes are caused to di# rectly separate from the drag, so as to free thel plates from the matrices beforethe copes are tilted away from the drag, and I also provide l.

novel means for .locking l,the copes to the drag.

The invention therefore consists in the nove 'constructions and combination of partsv 4o which protection is esired are summarized ally connected ,by links 2m.

hereinafter described,` and substantially illustrated-in the drawin sg-and the features for 1n the clalms. I

In said drawings-Figure 1 is a sidc elevation of the complete apparatus showing one cope in position vfor casting, and thc other open. Fig. 2 is atcp lan view ofFig. 1. The drag is proviA e with opposite casting faces 1, 1, :of the usual construction'ncccsvsary to give the proper form to the interior ol' the curved stereotype plates. Op iosite, and respectively adapted to coac't wit the faces 1, 1 a, ofthe drag, are copes'2 and 2a `pivotprovidedfwith trunnions 2P, having rol ers 2,l y which' they are supported on ways 9b'on a copes 2 and 2a, as shown.

These copesare f base 9, which ways extend on oppositesides of the drag and are preferably curved downwardly at each side of the drag sov that the copes are lowered as'tlley move away from Vthe drag and-will rise as they move toward the drag. l t

The co es are provided with the usual matrix retaining devices, which need no partic'ular` description herein, and also with handles'2d by which they can be' readily manipulated.' ratusv or casting stereotype plates for use on Each cope-is connected at its Lower end by pivot boltsA 3a to links 3, which are p'vot connected at their lower ends to links 3*", pivoted' at 3d tothe base 9.. These links 3, 3 cause the copes to oscil-late ,on their trunnions or rollers 2c as they'move to and' from ally the drag, the copes assuming a vertical position as they reach the drag, and a horizontal ,position as they move laway therefrom, as in` e present dicated yin the drawings.

The .outward movement of the links 3 is liniit'ed by .stops 9 on base 9 as shown in Fig. l, and thelinks 3c are pressed towardA the .stops .9 by springs '4 interposed between the lugs Qdionlbase 9 andthe links 3., The links 3, 3 notonly 'perform the function of causing the copes to swing from a vertical toa orizontal position as they' move away from the drag, but -they also cause the copes to separate directly from the'drag in the initial opening movements of the copes as hereinatei explained.

Pivoted'on the side of the drag are lock ing members 5, which'jare provided with hook ends 5a, respectively adapted to engage pins or studs 2e 4on the sides of the The locking meinbers are fixed on shafts 5b which extend through the cope and the shafts are provided at one end with arms 5*? which arc pivotally -connected to a link- V5d so that all the locking members arc rocked simultaneously to engage or discngage the pins on the copos. The locking members may bc actuated by a `lever 5e connected with one of the shafts 5, as shown.

When the locking members arc in engagement with one cope thcy discrigage Ithcother. As4 shown in Fig. 1 the cope 2a is closed and the hope 2 is opened. In this position a plate may be 'cast between thc drag v1a and the cope 2a, while a previously cast plate may be removed from the cope 2, or the matrix can be made ready therein. When cope '2 is ready for a casting ioperation, the

l operator first swings lever to the left so as to cause the hooks to release cope 2a. As he does this the springs 4, engaging the lefthand links 30, tend vlto forcethe lower end of the cope 2a directly away from the drag .1a and as soon as the o erator moves co e 2 toward the drag, cope 2'l is separated from the drag and the springs 4 force its lower end directly away from the drag 1.a so that there shall be no binding or biting between the v plate and the drag, and as cope 2 is closed,

performed between'one cope and drag, the.

other co e is being made ready, or having a previous y cast plate Withdrawn therefrom.

The links 3 and 30 and springs '4 perform the double function of causing the copes to oscillate on their t'runnions as theycmove to and from the drag and of preventing theV lower endsof the co es striking the lower end of` the drag, ant keep the copes from contacting the drag until forcibly drawn into contact therewith bythe hooks 5a; the vcopes being stopped when almost closed until they are engaged by the hooks, and then when engaged by the hooks they can be drawn directly toward the drag, thus in thefinal clos.

ing movement, and the initial opening movement, the copes move perpendicularly to the coacting faces of the drag. l

Having .described my invention what I claim as new and desire to secure by Letters Patent is:

l. 'lhe combination of a drag, a cope movable to and from the drag, links connected with the cope whereby it is caused to turn as it moves to and from the drag,A a spring whereby the cope is arrested when brought to a position parallel to the drag, and locking devices adapted to engage and actuate the cope in its final closing movement, said spring causing the cope to .move perpeinlieularly fgom the drag in the initial openingv movement thereof.

2. The combination of a stationary drag, a tiltable cope, supports for said cope, means for tilting said cope on its supports as it is moved to and from the drag, locking devices adapted to engage the cope when the same is brought into closing position before the drag, means `for arresting the cope when brought in its closing movement to a position parallel with the drag, said means being also adapted to separate the cope perpendicularly'fro'm the drag When it is released by the locking devices.

The combination of a stationary drag, a tiltable cope, supports for said cope, links and connections for tilting said cope on its lsupports as it is moved to and from the drag, locking vdevices adapted to engage the cope, springs for arresting the cope when brought to a position paralle with the drag in its closing movement, said springs being adapted to separate the cope perpendicularl from the drag ,when it is released by the ocking devicesfll- A 4J lln a stereotype casting apparatus the combjf `tion of a drag having opposite cast ing fait s, with a pair of copes on opposite sides the drag, and connected means wherebygwh'en one cope is closed the other is opened 5.
