ATTO EYS 9- 'A. J. STOUGES SLUG CASTING MACHINE Original Filed June 19, 1951 2 Sheets-Sheet 2 The rod (3 is mounted in fixed bearings D D and is provided between said bearings with a rigid block or collar and the bar M, located to the left of the collar C is formed with an elongated slot m through which the rod C extends. The side face of the bar M opposed to the bearing D is straight or vertical, while the other face, that opposed to the block 0*, is inclined upwardly to accord with the similarly inclined face of said block. As shown in Fig. 3, the block C is held resiliently engaged with the bar M by a compression spring. C seated in the bearing D and serving also to hold the bar; against the bearing D The jaw C moreover, is provided with a compression spring C mounted in a block D secured to the vise frame D, and which holds the jaw resiliently against the rod C As the parts are thus arranged, when the bar M is raised, the rod C and jaw C are forced positively thereby to the right or toward the opposing jaw C whereas when the bar is lowered, the rod C and jaw C are forced to the left or returned to their original positions by their. respective springs C and C The bar M is operated from the cam shaft R by means of afore-and-aft lever M which is connected to the lower end of the bar by an intermediate link M The upward movement of the bar M (in the present instance a positive one), is limited by a stop screw m which is arranged inthe vertical path of the lever M and hence the jaw C is always moved a definite distance by the bar M so as to locate the end matrices of a properly composed line positioned between the two clamping jaws in registry with the end walls of the mold slot.

If the line is of proper length, the movement of the left-hand jaw C will be imparted by the line to the right-hand jaw G which, under such circumstances, is adapted to yield toward the right against the tension of a spring C which normally holds it toward the left against a fixed stop D and which offers the resistance required for the lock-up of the line. The spring C is supported on a horizontal rod D rigidly mounted in a bracket D fastened to the vise frame D. In yielding, the jaw C is adapted to actuate the safety pump stop lever N common to the commercial linotype machines, and which, when actuated, permits the cycle of operation to proceed, the active mold being moved up against the matrix line and the pot plungers E being allowed to descend by action of the spring E hereinbefore mentioned. If the pump stop lever N is not actuated by the yielding of the jaw C the casting operation can not take place.

Although it is believed the operation of the mechanism will be readily understood from the foreging description, it might be here stated that the line of matrices being hand composed, is justified in the stick or holder, and delivered in such condition by the transporter B between the clamping jaws C C which normally are spaced apart a distance somewhat larger than the length of the line for this purpose. The left hand jaw is then actuated toward the right hand jaw to lock up the line for casting, the necessary clamping pressure being furnished by the yielding right hand jaw C as motion is imparted to it by the left hand jaw 0 through the intervening line as it is moved to place the inner faces of the end blank matrices in registry with the mold slot.

Having thus described my invention, what I claim is:

1. In a slug casting machine, adapted to be equipped with a non-expansible composed matrix line of a given length, the combination of a supporting frame, right and left hand clamping jaws mounted for horizontal movement in said frame, a transporter for positioning said matrix line between said jaws, positive means for moving the left hand jaw toward the opposing jaw from a normal to a definite predetermined position, said means having a range of movement sufficient to reduce the distance between the jaws to less than the length of said matrix line, a line-clamping spring arranged behind the right hand jaw to permit it to yield under the thrust of the left hand jaw through the composed matrix line, and a fixed stop to limit the yielding movement of the right hand jaw.

2. A combination as in claim 1, including a spring for returning the left hand jaw to its normal position, and characterized by the fact that the spring associated with the right hand jaw offers the sole resistance required for the justification of the line.

3. In a slug casting machine, the combination of a supporting frame, right and left hand clamping jaws mounted for horizontal movement in said frame, a transporter for positioning composed matrix lines of a given length between said jaws, a vertically reciprocatory wedge bar adapted in its upward movement to shift the left hand jaw to active position against the line, means for operating the wedge bar, and a fixed stop for limiting the upward movement of saidbar so as" supporting frame, right and left hand clamping jaws mounted in said frame and normally spaced apart for a distance corresponding approximately to the length of said matrix line, means for moving one of the jaws toward the other and having a range of movement sufiicient to reduce the distance between the jaws to less than the length of said matrix line, a transporter for positioning the matrix line between said jaws, and a lineclamping spring for moving one of said jaws against the line to exert a clamping pressure thereon.

6. In a slug casting machine, adapted to be equipped with a non-expansible composed matrix line of a given length, the combination of a supporting frame, right and left hand clamping jaws mounted in said frame and normally spaced apart for a distance corresponding approximately to the length of said matrix line, a transporter for positioning the matrix line between said jaws, means for moving one of the jaws toward the other and having a range of movement sufficient to reduce the distance between the'jaws to less than the length of said matrix line, a line-clamping spring for moving one of said jaws against the line to exert a clamping pressure thereon, and means comprising a fixed stop for limiting the movement of said jaw to position the line in predetermined relation with the mold.

'7. In a slug casting machine, the combination of a supporting frame, right and left hand clamping jaws mounted in said frame and spaced apart a predetermined distance to receive lines of a given length, a transporter for positioning composed matrix lines approximately of such length between said jaws, a vertically reciprocable wedge bar adapted in its upward movement to shift one of said jaws to exert clamping pressure against the line, means for operating the wedge bar, and a fixed stop for limiting the upward movement of said bar to fix the active position of said jaw so as to position the line in predetermined relation with the mold.

8. In a slug casting machine, the combination of a supporting frame, right and left hand clamping jaws mounted for horizontal movement in said frame, a transporter for positioning composed matrix lines of a given length between said jaws, a vertically reciprocatory wedge bar adapted in its upward movement to shift the left hand jaw to active position against the line, means for operating the wedge bar, a fixed stop for limiting the upward movement of said bar so as to locate the left hand jaw definitely in its active position, said right hand jaw being adapted to yield under the thrust of the left hand jaw through the composed matrix line, and a pump stop device actuated by the yielding movement of the right hand jaw.

9. In a slug casting machine, adapted to be equipped with a non-expansible composed matrix line of a given length, the combination of a supporting frame, right and, left-hand clamping jaws mounted in said frame and normally spaced 5 apart for a distance corresponding approximately to the length of said matrix line, both jaws normally occupying a position to the left of their active positions, means for moving the left-hand jaw toward the right to its active position and 10 through the composed line for moving the righthand jaw toward the right to its active position, said means having a range of movement sufiicient to reduce the distance between the jaws to less than the length of said matrix line, and 5 a line-clamping spring arranged behind the righthand jaw and resisting but permitting its rightward movement; whereby during casting the jaws are properly positioned and the composed line clamped under pressure between them.

10. A combination as in claim 9, characterized by the fact that the means for moving the lefthand jaw act only to move it toward the right and include a spring for restoring the jaw to its normal position to the left after casting. 25
