MACHINE FOR SETTING LAClNG-HOOKS.

SPECIFICATION forming part of Letters Patent No. 788,828, dated. May 2, 1905.

Application filed August 5, 1903. Serial No. 168,279.

To a, whom 712'; ntrty concern:

Be it known that I, WILLIAM A. I'IARGRAVES,

a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Setting Lacing-Hooks, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to machines for setting lacing-hooks, and has for its objects the ends commonly sought in such mechanisms. More particularly is it sought to eliminate the numerous elements formerly required in machines of this class and to provide an improved means of feeding and setting the hooks.

The above objects are attained by means of the mechanism whose construction and novel combination of parts constitute my invention. These are hereinafter described, and illustrated in the accompanying drawings, where- Figure 1 is a plan view of the bed of my new machine, omitting the head and hopper; Fig. 2, a vertical section of my machine on line w w of Fig. 1; Fig. 3, an enlarged plan View of the feeding mechanism, showing the parts in the positions assumed when the hook has been delivered to the die; Fig. 4, a similar view of the same, showing the position of the parts when engaging a hook; Fig. 5, a vertical section of the die on line ;1 1 of Fig. 4, and Fig. 6 a similar section of the same on line .2 of Fig. 4.

Like reference-numerals indicate similar parts throughout the views.

My machine comprises a bed 1 upon supports 2, surmounted by a head 3, provided with an anvil 4. Mounted to slide longitudi' nally in the machine-bed is a carrier-block 5, provided in its rear with a cam-roller 6 and a perforated lateral lug 7 to allow passage therethrough of a bar 8, whose forward end is fixed in an extension 9 of the bed. Intermediate the projections 7 and 9 the rod 8 is embraced by the spiral spring 10. The reciprocating carrier-block is actuated by means of a cam 11, contacting with the roller 6 and mounted upon the driving-shaft 12, which is journaled in the machine-bed. A rearward tension is ex- 5 erted upon the carrier-block by the spring 10.

Longitudinally disposed upon the carrierblock is a triangularly-shaped carrier-plate 13, whose point 20 is forwardly directed and preferably curved slightly. Upon the forward end of the carrier-block is a second plate or separator 14-, whose rear portion terminates in two projections 15 and 16. The former has a tapering base, while the latter is preferably rectangular in shape. The space between the points 15 and 9.0 is sufficient to allow the passage therethrough of ahook, and, as is clearly shown in Fig. I, there is formed at the junction of the tapering or inclined side of the finger 15 with thefinger 16 a pocket 5 for the reception of the book. This pocket lies wholly to one side of the line of travel of the point 20, and this entirely obviates any danger of the hooks being crushed in the advance of the plate 13.

In axial alinement with the anvil I isapost or plunger 17, mounted to vertically reciprocate in the bed 1 by means of a lever 18, pivoted intermediate its length to an arm 19, projecting downwardly from the bed. One 75 extremity of the lever is pivoted to the lower end of the post 17, while the other extremity carries a projection 21, which travels in the channeled cam 29. upon the driving-shaft. Fixed in the top of the plunger is die 23, 30 whose upper surface is flat and projects laterally to register with the raceway 26 when the plunger is in lowest position. A pocket 24-. in the upper part of the die forms a ledge or run 25 in continuation of the lateral exten- 5 sion just mentioned. To retain the hook in setting position upon the face of the die the following device is employed: To 2. lug 27 upon the side of the plunger is pivoted a holder 28, having an upwardly-inclined sur 9 face and an upright lateral flange 29, as shown in Fig. 5, also a small concavity 30, (shown in Fig. 6,) in which the hook rests during the setting operation. The holder 28 is retained in frictional engagement with the hook by means of a pin 31, vertically tensioned by a spiral spring 32, mounted in the die 23.

The operation of my machine is as follows: One of the lacing stud-hooks 33, resting in the raceway 26, is segregated from its fellows by the rearward travel of the point of the separator as the carrier-block retreats in its reciprocation, and the hook assumes the position in the separator shown in Fig. 4, where it rests until the forwardreciprocation of the carrier-block forces the inclined edge of the carrier 13 against. it, and the extreme limit of the outward throw of the carrier-block forces the hook into position upon the die 23, as shown in Fig. 3. Upon the retreat. of the carrier-block the cam 22, through the lever 18, raises the plunger 17 and'forcesthe eyelet portion of the lacing-hook, which rests upon the die, into contact with the anvil 4, thereby setting the eyelet. The plunger then descends to receive a second hook from the advancing carrier. The hook should be held comparatively firm upon the die during the upward thrust of the plunger, and this end is attained by the holder 28.

Having described my invention, what I claim 1. In a machine for setting lacing-hooks, the combination of a raceway and means for feeding the hooks thereth rough hook by hook, of a die-carrying plunger; a die mounted in said plunger and provided with a lateral extension and a pocket in continuation of said lateral extension, said extension registering in the lowest position of the plunger with the raceway; and a spring-controlled holder pivotally mounted in said plunger and formed with a retaining-flange which coacts with said pocket.

2. The combination with a plunger having a lateral projection, of a die seated in the plunger and provided with a pocket for the reception of a hook, a hook-holding member pivoted to the projection and extending into the pocket of the die, and a spring-pressed pin mounted in the die and engaging the hookholding member.

In testimony whereof I have aflixed my signature in presence of two witnesses.
