PRESS.

Application filed October 11, 1915.

being had to the accompanying drawings,

forming a part hereof.

My invention has relation to improve ments in presses; and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.

The present is an improvement on a form of press commonly employed for pressing a number of out-soles with their complement of slips or linings, for the purpose of cementing the parts together, examples of which press may be found in U. S. Letters Patent numbered 1,098,699, dated June 2 1914, granted jointly to myself and William Jones, the object of the present invention being to provide such a press with a special form of looking or gripping device by which the telescoping members of the press between which the stock is compressed may be held against separation when the final pressure on the stock is applied; to provide a locking device which will permit instantaneous disengagement of the press members when the stock is to be removed; to simplify the construction of the press as a whole, and to provide other features of construction the advantages of which will fully appear from the following detailed descriptionof the invention in connection with the accompanying drawings in which- Figure 1 is a side elevation of the press with stock shown dotted; Fig. 2 is an end elevation of the press with stock removed; Fig. 3 is an enlarged end eleva-tional'detail of the loop or strap of one of the press members through which operates the grooved arm of the telescoping member; Fig. 4 is a view similar to Fig. 3, but with the outer wall of the loop or housing removed, the housing being shown in vertical section; Fig. 5 is a combined inside elevational view and vertical section on the zig-zagline 5-5 of Fig. 3, of the telescoping arms of the press members or sections; and Fig. 6 is a cross-section on the line 66 of Fig. 3.

Referring to the drawings,'1 represents a U-shaped member the arms whereof terminate in loops or straps 2, provided with pas- Specification of Letters Patent.

sage-ways p for the traverse of the arms of a complementary telescoping U-shaped member 1, the outer faces. of whose arms are provided with transverse corrugations a. Mounted rotatably in the side Walls of the straps or loops 2, about axes disposed parallel to the longitudinal axes of the corrugations a are cylindrical rocker-spindles 3 terminating at one end in a wing or lobe 4, the wings of the respective spindles being on opposite sides of the respective straps, that is to say, the wing on one spindle is on one side of the press, that on the opposite spindle being disposed on the opposite side of the press for convenience of manipulating the press members or sections. The spindle 3 traverses a socket or recess it formed in the solid portion of the strap, said recess being in free communication with the passage 3? as shown to best advantage in Fig. 4. Both sides of the press are alike so that a description of one side will answer for both. Socured to the spindle 3 and operating in the recess or socketh is a dog'or block or equivalent catch 5 (the spindle having a drive fit through the dog) which for a certain inclined position is adapted to engage the cor rugations a of the adjacent arm of the U- shaped member 1, thereby locking the member against an outward or expanding movement, the dog 5 and corrugations a acting very much on the principle of a pawl and rackbar. The tendency of the dog is to present its lower free edge to the corrugations a by reason of the draft of the coiled contracting spring 6 one end of which is secured to a lug 7 disposed to one side of the rotation axis of the wing 4 at the inner end of the wing, the opposite end of the spring being coupled near the base of locking latch or pawl S hinged to the side face of the strap 2, a securing screw 9 serving as the fulcrum for said pawl, the latter being mounted loosely about said screw 9. The edge of the pawl facing the wing 4 is'undercut leaving an outer terminal lobe formation or finger hold 8 by which the pawl may be readily seized and lifted for purposes of manipulation. Along the undercut edge of the pawl 8 is formed a notch or recess 7, said pawl operating to engage the adjacent edge of the wing 4: when the latter is oscillated sufliciently to bring the outer face of the block or dog 5 into parallelism with the arm of the member 1, that is, parallel to the direction of movement of said arm, when the block or dog will be wholly disengaged from the corrugations (4, thus permitting the member 1 to be freely withdrawn from the loops or straps of the member 1. The outward movement of the pawl 8 is limited by a pin 10 as shown.

The cross-bar of the bottom U-shaped member of section 1 is provided with a board of stock-supporting platform P, the sides of which are provided on either side of the member 1 with anchoring or fastening loops 11 for securing the detachable ends of the cords 12 passed around the stock S to be pressed, the opposite ends of the cords being permanently secured to the opposite side of the platform by means of nails or screws 13, as fully shown and described in my pending application for shoe-sole press attachments Serial Number 875,669, filed December 5, 1914. The stock is held in position between the bottom platform P and the upper presser-plate P which is loosely connected to the upper cylindrical cross-bar of the member 1 by a U-shaped bracket 14 the terminal arms of which are provided with vertically elongated slots m to afford free vertical play to the presserplate to and from the stock S. The presserplate is controlled by the cams C of an actuating lever 15 pivoted about the cross-bar of the member 1 between the slotted arms of the bracket 14, the arrangement being on the order described in my U,. S. Letters Patent 1,126,325, dated January 26, 1915.

The operation of the press is substantially as follows: Let us assume that the stock S is placed on the platform P and securely tied by the cords 12 in readiness to be compressed. Let us further assume that the upper section or press member 1 is wholly withdrawn from the loops or straps 2. The stock being in position on the platform P, the operator inserts the arms of the member 1 into the passage-ways 7) of the straps, the corrugations a freely riding over the inner edges of the dogs 5, the same as a ratchet rides freely over a pawl in a given direction. The wing 4 when released assumes the position shown in Fig. 3 under the tension of the spring 6, and when the arm of the member 1 is inserted into the passage 7) of the loop 2, the dog 5 is readily oscillated to make way'for the arm, the dog being tripped to cause the wing 4 to assume an intermediate position shown by the dotted lines in Fig. 3, that is to say a position wherein the upper edge of the wing comes between the lobe s and recess 7* of the locking pawl 8. lVhen the member 1 has been inserted (through the loops 2) suificiently to cause the pressure-plate P to engage the upper surface of the stock S, the operator swings the lever 15 to the right (see arrow Fig. 1) or in proper direction to cause the camsG to force the plate firmly against the stock, thus compressing the latter. The reaction of the stock thus compressed between the members P, P, tends to force the members 1, 1, apart (see arrows Fig. 3), causing the dogs 5 to exert a grip on the corrugated faces of the arms of the member 1, and preventing movement of said member. Thus the stock remains under compression until permanently set, or until the slips are cemented, the operator rocks the spindles 3' by seizing'the wings 4 and oscillating the latter until their upper edges (riding along the curved undercuts of the pawls) come opposite the recesses 1" of the pawls, when the springs 6 will automatically draw the recesses over the wings (Fig. 4) and cause the wings to be locked. hen however, the wings 4 are in engagement with the recesses 1 of the pawls 8, the dogs 5 are in position as shown in Fig. 4, that is to say their outer faces are parallel to thearms of the member 1, and the dogs are Wholly disengagedfrom the corrugations a, permitting the member 1 to be readily withdrawn from the loops 2, and the stock removed. To treat a fresh lot of stock, the operator first lifts and releases the pawls or latches 8 from the wings 4, thereby disengaging the latter from the recesses 7", the tension of the spring 6 rotating and restoring the wings and dogs to the position indicated in Fig. 3, thus bringing the parts back to their original position, the loops 2 being free to again receive the arms of the member 1 and the dogs locking or gripping the same against outward movement, that'is to say, a movement tending to separate the members 1, 1. Before removing the member 1 at the conclusion of the cementing operation, it is best to swing the lever 15 back to its original position (Fig. 1) just prior to the disengagement of the wings 4 from the recesses of the locking pawls 8.

Having described my invention what I claim is:

1. In combination with a pair of members connected telescopically with one another, a rotatable catch operating to grip one of the members and prevent movement between the members in one direction, a spring for normally maintaining the catch in gripping engagement with its member, and means coupled to the spring on the member supporting the catch for maintaining the latter out of engagement with the opposite member.
