STEREOTYPE-CASTING MOLD.

Patented Sept. 19, 1905.

Application filed July 3, 1901. Serial No. 66,975.

- by plates will be cast more perfectly in less time and with less labor than heretofore.

Casting-boxes 'of this character are usually constructed so that the drag is in a horizontal position when the matrix is introduced, the cope being laid down on the drag whilein this position, both cope and drag being raised to a perpendicular position when the plate is being cast, both cope and drag beinglowered again to a horizontal position after the plate is cast, and the cope thereupon moved into a vertical position in order to remove the plate. The cope is usually hinged to the drag, either at its side, as in Patent No. 243,981, of July 5, 1881, or at its end, as shown in Patent No. 583,090, dated May 25, 1897, the cope being balanced by weights or springs in order to facilitate the moving of it from one position into the other. It has also been customary to bind the drag and cope together by meansv of clamps and screws and also to use eccentrics or cams for the purpose of separating them after the plate has been cast.

I shall describe a mold for casting stereotype or other plates embodying my invention and afterward point out the novel features in the claims.

In my improved machine I place the cope stationary on the framework and in an upright position nearly perpendicular. The drag is made movable from a horizontal position into an upright position substantially parallel to the cope, and vice versa, the means for accomplishing or effecting this being so constructed as to guide the dragso as to make it practically self-balanced or maintain it in I an equilibrium when in either position or while moving from one position to another. By thismeans I am enabled to dispense with clamps and cams for fastening and releasing the parts. A further advantage gained by this construction lies in the fact that Iam enabled to make a mold which is low at the metal-receiving end, while the drag is also of a convenient height when in its horizontal position for receiving the matrix and removing the plate.

In order to facilitate the shaving of the plate to a uniform thickness, the cope may have circumferential rings around its surface at the point where the plate is to be cast. When a plate is to be cast with these ribs, which are usually about one-sixteenth of an inch high, it is necessary that the drag should have a sliding motion backward while it remains in a position substantially parallel with the cope, so that the ribs of the plate will be out of the grooves or rings in the cope before the drag begins to move into its horizontal position. Accordingly I construct the drag with segmental rockers adapted to rock upon fixed rails on the framework to change the drag from a horizontal to an upright position, or vice versa, and, further, with means for moving the drag in a straight line for a short distance while engaging or disengaging with the cope, the parts being preferably so arranged that the movement from the hori zontal to the vertical position, and vice versa, and in a straight direction toward and away from the cope is uninterrupted.

Other improvements. will appear as the specification proceeds.

the circular end gage, showing the pin on which it turns. Fig. 5 shows a portion with hinge of one of the side gages. Fig. 6 shows a mod1ficat1on for guiding the rockers in position.

Similar letters of reference indicate corresponding parts in the different views.

A represents a framework mounting the several parts composing the casting-box. B is the cope, fastened to one end of this frame inanearly-perpendicular position. The drag G is fixed on the segmental rockers c and 0 having each a straight portion 0 which roll on the friction-rolls e, and an arc-shaped portion 0 which rocks on the rails e and 6*. On the rockers c'and c are fastened the cams CZ IIO and (V, which engage with the-rolls e and a" on the framework.

G is a rock-shaft extending through the frame A, to which shaft are fastened two arms g and and the operating-lever 9 Mounted on the rockers 0 and c is the rock-shaft H. to which are fastened the arms 7i and 71,2. The opposite ends of these arms are connected by means of the bolts or pins 6 to the arms 9' and g Hinged to each side of the drag C are side gages 0 and 0 The hinges 0 of these gages are raised a considerable distance above the level of the face, which is fastened to the rockers 0 and 0 and the gage which comes in contact with the drag (J. These hinges being so raised act to prevent the gages from lifting whilethey are in contact with the cope B, and thereby compel them to follow the drag when it is being drawn away from the cope, and thereby prevent the plate from sticking to the cope. These gages are rabbeted on their under sides, as shown in Fig. 5 at 0, so as to receive the edge of the matrix when placed in position to cast the plate, while a handle 0 is attached to facilitate their manipulation. The circular end gage I is also rabbeted on the edge, as indicated at in Fig. 4, and is pivoted at each side on the pins e". Fastened to the upper end of the cope B is a bar 6, against which the drag C rests as it is brought into an upright position to properly gage the thickness of the plates to be cast, the end gage I acting for the same purpose on the lower end of the cope B. On the end of the bar I) may be placed a spring-seated pin 1), which rests against the gage 0 so that when the drag is pulled away from the cope this pin, by means of the spring, will follow against the gage, and thereby assist in pushing the plate awayfrom the cope B. This spring-pin may be put on the bar I) at both ends, although it is only shown on one end. y

In order that the rockers 0 and 0 may not slip and get out of positionon the rails e and e, I employ a rack, as K, having a projection 76 at one end, bolted to 0, which engages with pins k, fastened to the frame A.

The operation is as follows: When the drag C is in the horizontal position, the matrix, having paper or steel tailpieces, is placed underneath the side and end gages, thus securing it in position. When in this position, the drag is about half-way between the upper and lower end of the cope, which is a convenient position for inserting the matrix and for removing the plate. By means of the lever g the operator rocks the drag(] until it comes in an upright position parallel to, or nearly so, with the cope B. At this moment the projection k engages the last of the pins k and the cams OZ and d engage with the rolls 0 and e to facilitate the changing of the rocking motion to a sliding motion, and the ends of the rockers -0 and c engage with the rolls 6, the movement of the drag also being facilitated by its passing over the roll 0 A further motion of the lever g will then, by means of the togglejoints formed by the arms 9 and g and it and 72 push the drag C uninterruptedly and its gages up against the cope B in position to cast the plate, undue movement being prevented by the stops it and carried by the arms g g and it if. When the plate is cast, by means of the lever g the drag C is brought into the horizontal position, the side gages are folded outwar'd by manipulating the handles 0 the plate is pushed forward by means of the end gage I, operated by the handles and is then removed in the usual way.

When the rack of the rockers 0 and 0 is not used, I place a stop, as L, on the frame, against which the ends of the rockers c and c at Z rest when the drag is in its horizontal position. It will thus be noted that the end of the rockers p and 0 coming in contact with the stop L, and the cams d and (Z on the rockers, coming in contact with the rolls 0 and-e,- will prevent the drag from getting out of its proper place.

In Fig. 6 I have shown a modification in which I employ an additional piece on the rockers, as R, which may be cam-shaped, adapted to engage with a pin or stop, as 7", on the framework at the time when the direction of the movement is changed.

The rails on which the rockers rest are I\- shaped, the rockers similarly shaped, so as to guide the rockers laterally and also to prevent any metal which might fall thereon when pouring it into the mold from lodging on the rails.

As is usual. the cope B is made hollow and provided with a pipe or pipes inside for the circulation of water, with suitable inlet and outlet for the purpose of keeping it cool, the water also filling the hollow space in the cope. It is of course also possible to have the drag stationary and the cope rocking.

In some of the claims the means for moving the movable part are described as moving it from a horizontal position to the upright position only; but it will of course be understood that the same means move it back to the original position and the claims should be so construed.
