STOP FOR LACING-HQOOK-SET-TING"MACHINES.

SPECIFICATION forming part of Letters Patent No. 739,106, dated September 15, 1903. Application filed December 29, 1902. Serial No. 136,974. (No model.)

To all whom it may concern;

Be it known that 1, JOHN PIERCE, a citizen of the United States, residing at Milton, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Stops for Lacin g-Hook-Settin g Machines,of which the following is a Specification.

v This invention relates to that class of ma chines in which articlesf-such as lacing; hooks, buttons, rivets, and the likeare fed from the hopper to a raceway and are taken from the raceway one by one after being set or attached to a piece of sheet material. I have illustrated and described my invention as ada ted to a machine for setting lacing-hooks, sai machine being Substantially the same as that for which I have obtained Letters Patent of the United States, dated July 9, 1901, No. 678,028, with the exception that the stop for the lacing-hooks 'is provided with a spring-latch, the object of said latch being to yield and allow the lacing-hook to. be drawn past the stop on the raceway; and, further, the object of the invention is to prevent the lacing -hok from being jammed in cases Where the operator has not moved thelacinghook set in the material beyond the stop before said stop arrives at its lowermost position, so that the lower edge of the stop strikes upon the top of the lacing-hook. The yieldin g latch pivoted to the stop prevents marring the hook in this latter case.

The invention consists, in a machine of the character described, of a raceway, an anvil,

a pivotally-mounted stop located at one side of aplane extendingthrough the center of said anvil and intersecting the path of the lacing-hooks on said raceway'as they approach said anvil, a spring-latch pivoted to said top, and mechanism for impartinga rocking motion to said stop. i

The invention, again, consists, in a machine for setting lacing-hooks and the'like in sheet material, of the combination of an anvil, a

plunger, mechanism for imparting a recipro-.

catory motion to saidplunger, a raceway fast to said plunger, a stop pivoted to said plunger, a spring-latch pivoted to said stop and normally projecting below the lower edge thereof,

and mechanism to impart a rocking motion to said stop.

' The invention further consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a right-hand side elevation of a portion of a lacing-hook-setting machine similar to that shown and described in my United States Letters Patent No. 657, 673,with the improved stop' forming the subject-matter of this ap= plication attached thereto. Fig. 2 is a ver tical sectional elevation taken'on line 2 2 of 1 looking toward the left in said figure.

'Fig. 3 is a rear elevation of a portion of the plunger, raceway, separator, and Stop, with a number of lacing-hooks on said raceway, the same being shown full size and starting to descend. Fig. 4 is a View similar to Fig. 3, with the parts shown in the relative positions assumed when the plunger is in its lowermost position and the lacing-hook set in the material is being moved by the operator along the raceway. Fig. 5 isan enlarged righthand side elevation of the parts shown in Fig. 3.- Fig. 6 is a side elevation of the parts shown in Fig. 4. Fig. 7 is a detail section on line 7 of Fig. 5. Fig. 8 is an enlarged righthand side elevation of my improved Stop. Fig. 9 is a left-hand side elevation of the same. Fig. 10 is a perspective view of the separator-plate, look-plate, and rocker-shaft.

Like numerals refer to'like parts throughpivoted at '15 to the frame 11.

The lacing-hooks are delivered from a hopper 16 by a picker-plate 17 to a raceway 1S,

fast to the plunger 12. Said raceway extends vertically downward from the hopper 16 and is bent at right angles at the bottom 19 thereof to a horizontal position beneath the plunger 12 is a spring-washer 23, which holds said separator, rock-shaft, and stop in any position to which they may be moved, as hereinafter described. The stop 22 has a finger 24: thereon, which abuts against a stop 25, fast to the frame of the machine, when the plunger 12 and raceway 18 are nearly arrived at their lowermost positions, tipping the stop and the separator from the position shown in Fig. 5 to that shown in Fig. 6. \Vhen the plunger 12 and raceway 1S ascend, together with the separator and stop-plate 22, a pin 26, fast to the stop-plate 22, strikes against the frame 11 of the machine and rocks the separator 21 and stop-plate 22, together'with the rock-shaft 20, from the position'shown in Fig. (3 to that shown in Fig. 5. The stopplate 22 is provided with a flattened'surface 27 upon its lower edge and with another flattened surface 28.

A latch 29 is pivoted at 30 to the plate 22 and is located in a recess 31, provided in said stop-plate. Said latch has a shoulder 32 thereon, which abuts against a shoulder 33, provided on the stop-plate 22, and is normally held against said shoulder by a flat spring 34, located in the recess 31. The latch 29 is beveled at 35 upon the side thereof'adjacent to the anvil and upon the lower edge of said latch.

The operation of my improved rocking stop in conjunction with the vertically-reciprocating plunger, raceway, and separator-plate is as follows: The lacing-hooks are delivered to the raceway 18 from the picker-plate 17 and slide down said racewayto the position'shown in Fig. The lowermost lacing-hook '36 resting upon the short horizontal portion 19. of the raceway 18, with the'left side *of the head of said lacing-hook touching the right side of the latch 29 upon the stop-plate 22, the weight of the hook 37 and the column of hooks on the raceway pushes the'hook 36 into the position shown in Figs. 2 and-3and brings said hook into a vertical position directly above the center of the anvil 38. The plunger 12is shown raised in Figs. 2-and 3 and just beginning to descend. The operator'next places the upper of the shoe in the proper 'position over the anvil 38, Fig. 2, and the plunger descends. As the plunger de'scends'the rock-shaft 20, with the stop andseparator plates fast thereto, remains stationary with relation to the plunger and raceway until just before the shank of the lacing-hook'36 a'buts against the upper face of the 'leather'of the shoe-upper, when the finger 21 strikes "the stop 25 and tips the separator-and stop- plates 21 and 22, respectively, together with the rockfrom the raceway at any time after said lacing-hook has cleared the top of the anvil 3S and until the pin 26 strikes the frame 11 of the machine, as the heads of the lacing-hooks are free to pass along the horizontal portion of the raceway and beneath the flat surface 28 upon the stop-plate 22 without contacting with said stop-plate. At the last part of the upward motion of the plunger the position of the separator and stop plates will be reversed and the depression 40 in the periphery of the separator-plate will come in line with the lacing-hooks upon the raceway, allowing the lowermost hook in the column of hooks on the raceway to pass down said raceway and against the right-hand side of the latch 29, which by that time will have been rocked into position in line with the lacing-hooks upon said raceway. It will also be seen that the lowermost hook in the column of hooks on the raceway has all of the time occupied by the plunger in descending from its uppermost position to the point at which the finger 24 encounters the stop 25 in which to travel along said raceway to a position immediately above the anvil'38 and between the separator andstop' plates. It will further be seen and understood that the rocking of the shaft 20 and 'of the stop and separator plates fast thereto takes place just as the lacing-hook enters the'upper39 of the shoe, so that the head of said lacing-hook is held between the separator and stop plates as the shank of the lacing-hook first enters the upper and while it is passing through it, and thus holds said lacing-hook firmly in position during the setting operation.

It will be particularly noted, as herei-nbefo're set forth, that with a stop-plate constructed'as hereinbefore deseribed,'-having a spring-latch pivoted thereto and projecting below the lower edge of said stop-plate, the lacing-hook, which has been set in the upper, as hereinbefore described, may be removed from the horizontal portion of the raceway by the operator at any time after the shank of the'lacing-hook'has cleared the top of the anvil. During the upward motion of the 'p'lungeiy'as herein'before described, the top of the lacing-hook is free'to' be removed from the raceway as soon as said lacing-hook clears theanvil 19. lVhen the stop-plate has been tipped, as he'rein'be'fore described, from the position shown in Fig. 6 to that shown in Fig; 5 at the'extrem'e of its upward movement and during its downwardmo'vement, the lacing-hook 36 may be removed by the operator by pulling the upper, together with said lac- ICO 'ing-hook, past the latch 29, said latch yielding to allow the head of the lacing-hook to pass thereby, this operation being facilitated by the beveled edge upon the inner and lower edge of said latch, and, further, it will be noted that if through mistake of the operator or inaccuracy in feeding'the upper by said operator a lacing-hook should come beneath the stop when said stop is nearing its lowermost position and the latch 29 should come in contact with the top of said lacinghook then said latch will yield without injuring said lacing-hook.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a machine for attaching lacing-hooks and the like to sheet material, an anvil, a

raceway, a pivotally-mounted stop located at plunger, mechanism for imparting a reciprocatory motion to said plunger, a raceway fast to said plunger, a stop pivoted to said plunger, a spring-latch pivoted to said stop and normally projecting below the lower edge thereof, and mechanism to impart a rocking motion to said stop 3.
