To all whom it may concern:

Be it known that I, HERMAN WINTER, of the borough of Brooklyn, of the city of New York, in the State of New York, have invented certain new and useful Improvements in Apparatuses for Making Stereotype- Plates, of which the following is a specification, reference being had to the accompanying drawings forming a part hereof.

In the use of stereotype plates with a curved cross-section, that is stereotype plates having a substantially semi-cylindrical shape, it is often advantageous to have the plates comprise a segment of more than 180 degrees or in other words to have the cylindrical plates greater in extent than that of a semicircle. For by such means it not only happens that a wider range in the size of plates that can be manufactured by a particular machine, is permitted, but the form of the plates which comprise a segment greater than 180 degrees, particularly adapts them for use in certain kinds of presses.

Heretofore with a semi-cylindrical drag and a correspondingly shaped cope, which was adapted to be inserted into and withdrawn from the open side of the drag, no stereotype plates, as is obvious, could be made with a curvature greater than 180 degrees.

It is accordingly one of the objects of the present invention to provide an apparatus of this general character in which it will be possible to cast stereotype plates comprising a segment greater than 180 degrees.

Other objects of the invention are to improve such apparatuses in different details all of which will be referred to hereinafter and in connection with the drawings in which a practical apparatus embodying the invention is shown.

In said drawings Figure l is a view in side elevation of this apparatus, Fig. 2 is a view in front elevation, Fig. 3 is a view in side elevation with the casting box partly in section and shown in its vertical position, Fig. 4 is a view in front elevation of the casting box showing the two parts of the cope drawn together or collapsed, Figs. 5 and 6 are detail sectional views of a portion of one of the clamps for securing the cope to the drag,

. Figs- 7 and 8 are detail views of the head gage, and Fig. 9 is a detail broken view showing one of the pivoted side gages and the strip to which it is pivoted.

The casting box A, as usual, may be provided with trunnions a and pivoted upon a frame B, whereby it may assume a horizontal position for the insertion of the matrix and for the removal of the finished plate or a vertical position for the casting of the plate. For holding the casting box in a horizontal position, one or more bell crank lovers 1) may be provided pivoted to the frame B and means such as a foot press I) may also be provided to disengage the levers b from the casting box said levers being normally held in their engaging position by a spring 6 Stops b and b are preferably placed upon the frame B so as to assist in supporting and steadying the casting box when it is in its horizontal and vertical positions respec tively.

The cope O of the casting box, is pivoted to the rear end of the drag at c and is r0- vided with a weight (Z and a cord (1 which latter is secured thereto and runs over a pulley 61 back of the casting box, whereby the cope can be conveniently manipulated upon its hinge by the operator.

The segment comprised by the drag, as will be seen from Figs. 2 and 4, is somewhat greater than 180 degrees, the precise extent, however, over 180 degrees being unimportant. In order to permit the cope to be readily inserted into and withdrawn from the opening in the upper side of the drag, said cope is split lengthwise and thus comprises two parts or sides, 0 and c, which are arranged so as to be readily collapsed and expanded, as required. Thus, when the cope is collapsed, it may be readily moved into and out of the drag, and after the cope has been moved into the drag it may be expanded so as to occu y the proper position with reference to the si es of the drag and the matrix m for casting. For this purpose the two sides of the cope c and c are preferably pivoted, as shown in Fig. 3, to a central support 0 for the cope, said support being ivoted or hinged at c, as already stated and having toward its forward end a cross bar 0 which, through means such as adjustable screws 0 is supported on the drag, near the forward end thereof. As

' clamping.

shown the cope support 0 has two pins 0 upon which the sides 0 and c are pivoted.

In order to expand and collapse the two sides of the cope, they may be connected at the top by means of links 6 to a crank 6 fast upon a shaft 6 rotatable in the cope support, a lever e being provided whereby the shaft 6 may be rotated at will and the cope sides expanded or contracted as the case may be. Preferably the shaft 6 extends substantially the length of the cope and is connected to the sides of the cope in the manner described above, at both ends thereof.

When the cope has been inserted into the drag and is extended as just described, it is firmly secured to the drag by clamps f, of which there are preferably four, one on each side near the front and near the rear of the casting box. Each of these clamps is mounted loosely on a shaft f which has an eccentric bearing or pivot f to which a handle f is secured. The clamps are adapted to engage lugs f 4 on the cope, and when they have been brought to engage said lugs, the handles are moved so as to rotate the shafts f u on their eccentric pivots whereby said 0 amps are tightened against the lugs. j, Fig. 1 shows the position of the clamps f and the handles f before the clamping and Fig. 2 the position of these parts after the Furthermore each of the clamps is provided with a spring f 5 which encircles its pivot f and one end of which spring engages the clamp while the other end engages the shaft upon which the clamp is pivoted. The spring thus normally tends to hold the clamp back from its lug in a substantially vertical position, as shown in Fig. 4, whereby it will not be in the way as the cope is moved into and drawn out of the opening in the top of the drag.

The apparatus is provided, as usual, with a head gage g, which may comprise a band with conveniently formed handles and adapted to be sprung into the rear end or head of the drag, and side gages h, which in the present 1 spring clamp handle is provided.

case are pivoted to a long strip h, which is screwed onto either side of the drag. The matrix is secured in the drag, as usual, by means of the gages, and the pivoting of the side gages makes the operatlon of securing and releasing the matrix particularly convenient.

In addition to the head and side gages there is provided what will be referred to as a split gage, which in the present case, consists of a long bar or strip 76 adapted to fit in tightly and in a lengthwise position between the cope C and the matrix m. This gage is provided so'that plates of different sizes may be cast as desired. In order to hold this gage in position and to move it about from one part of the casting box to another pat, 3

a1 spring clamp handle may comprise an extension on the bar or strip 7c projecting somewhat beyond the end of the casting box and a member 76 pivoted thereto with a projection k upon the inner end thereof which fits in a small groove behind a shoulder k which runs around the front end of the drag. A spring k is provided between the member 7c and the extension of the strip 7c whereby the projection 76 is held tightly in said groove. When it is desired to change the position of the split gage in the casting box the handle is grasped by the operator and the member 7c is moved against the action of the spring k thus Withdrawing the projection W from the groove behind the shoulder it. When the gage has been properly adjusted, the operator lets go the handle and the gage is automatically fastened, as will be clear from Fig. 3 of the drawing. It will be understood that the casting operation is performed when the casting-box is in its vertical position, as shown in Fig. 3, 'and after the plate has been cast the box is tilted to its horizontal position, as shown in Fig. 1, the cope being collapsed and moved out of the drag, and the plate removed through the front end of the drag, or,

by rotatingit about one-quarter, it may be lifted out through the opening in the top of the drag.

Various changes may be made in the construction of the apparatus herein shown and described without departing from the inven tion, and the scope of the invention is accordingly not limited to the embodiment of the improvements herein specifically referred to.
