Application filed July 17, 1902. Serial No. 115.909.- (No modehi To aZZ whom it may concern: 'Be it known that 1, WILLIAM P. BARTEL,

citizen of the United States, residing at Wal th'am; in the county of Middlesex and State of Massachusetts, h'aveinvented new and useful Improvements in Lacing-Hook-Setting Maapplication for Letters Patent, Serial No.

The object of the inventionis to providea convenient, strong, simple, and durable machine which shall be capable of being run at. a high speed and efficiently feed the lacinghooks to the proper point above the centerof the anvil and set the same in the upper of a boot or shoe without injury to or defacement of the hook.

The invention consists in improved mech-' anism for separating the lacing-hooks upon the raceway and feeding them one by one'to. a feed-wheel provided with recesses upon its periphery and jou rnaled upon areciprocatory plunger, said feed-wheel carrying the books point above the anvil. The particular means for separating and feeding the lacing-hooks one by one to said feed-wheel consists ofa feed-lever which is rocked downwardly across the path of the lacing-hooks upon theraceway and forces the lacking-hooks, pref-' erably with a yielding pressure, one by one into the recesses formed in the peripheryof the feed-wheel, holding each lacing-hook in turn-before it istaken .by the feed-wheel downwardly, so that upon the upward motion of the plunger'said lacing-hook will not be thrown upwardly in the raceway into such a .feed-wheel between the depressions therein, stop the feeding of the hooks, and jam said hooks. The means for feeding the lacing.

hooks one by one to the feed-wheel consists, in addition to the feed-lever .hereinbefore referred to, of a separator-leverwhereby a single hook is taken from a column of hooks on the raceway extending from ,the Separatorlever to the hopper from which the hooks are obtained and dropped one by one down th raceway to said feed-lever.

The-invention again consists in specific mechanism for intermittently rotating the feed-wheel and again in-themanner in which a guide'and driver, comprisinga plate having a curved flange integral therewith and extending from one face of said plate at right angles across the periphery of the feedwheel, is fastened to a reciprocator-y plunger, whereby a lacing-hook having a little thicker head than the average lacing-hook being used in the machine may be fed by the feed-wheel-aroundthe curved flange referred to without injury-to'the hook.

The invention finally consists in the combination and, arrangement of parts set forth in. the following. specification and particularly pointed out in theclaims thereof.

Referringtto the drawings, Figure l is a frontelevation of my improvedmachine for lacing-hooks- Fig. 2 is aside eleva- ?same as viewed from the left ,of Figlrlr same asviewed from the right of Fig. 1. Fig. 4 is a side elevation of a portion of the machine as viewed from the right of Fig. 1, being a view similar to Fig. 3 with the plunger raised. taken on line 5 5 of Fig. 4:, illustrating the mechanism ;for intermittently rotating the -feed-wheel, theparts being shown in their relative positions when the plunger is raised.

Fig. 5 is a detail section tion of the parts for imparting an intermittent rotation to the feed-wheel when the plunger is lowered. Fig. 7 is a detail side elevation of the lacing-hook-feed lever and parts connected therewith as viewed from the right, in Fig. 4. Fig. 8 is an enlarge l detail -sece tion, partly in elevation, taken on line 8 8 of Fig. 1, showing a portion of the plunger and guide and driver and the manner of attaching the said guide and driver to the plunger, the feed-wheel, and the ratchet by which it is driven. Fig. 9 is a detail section, partly in elevatiomtaken on line 9 9 of Fig. 8. Fig. 10 is a detail view similar to Fig. 4, illustrating the relative location of the feed-lever and separator-lever and the raceway when the plunger is about one-half way between its upper and lowermost position. Fig. 11 is a detail section taken on line l1 11 of Fig. 8.

Like characters refer to like parts throughout the several views of the drawings.

In the drawings, 15 is the frame of myimproved lacing-hook-setting machine. 16 is the main driving-shaft, journaled to rotate in bearings 17 17 upon said frame. The driving-shaft-16 is rotated by means of a clutchpulley 18 of any desirable construction and has a pinion-gear 19 fast thereto and meshing into a gear 20. The gear 20 is fast to a shaft 21, journaled to rotate in bearings 22 22 upon the frame of the machine. A plunger 23, guided in ways 24, formedin the frame of the machine, has a vertical reciprocatory movement imparted thereto by a crank-pin 25, fast to a disk 26, integral with the shaft 21. The crank-pin 25 is connected by a rod 27 to two links 28 29. The links 28 and 29 are pivotally connected to each other and to the rod 27, the upper end of the link 28 being pivoted upon a pin 30, fast in the frame of the machine, and the lower end of the link 29 being connected bya pin 31 to the upper end of the reciprocatory plunger 23.

To the lower end of the plunger 23 is fastened a guide and driver 32, consisting of a plate 33, fast to said plunger and having a curved flange 34 integral therewith and projecting at right angles to one face thereof across the periphery of a feed-wheel 35. The plate 33 is fastened to the plunger 23 by a screw 36, which is fast to the plunger 23 and extends through a slot 37, provided in the plate 33. The plate 33 abuts atits upper end against a shoulder 38, formed upon the plun ger 23. The slot 37 may be made circular, of a diameter larger than the diameter of the screw 36. The object of fastening the plate 33 to the plunger 23, as hereinbefore described, is to allow a lacing-hook having a head thicker than the average lacing-hook being used upon the machine to be fed around the curved flange 34 by the intermittentlyrotated feed-wheel 35 without injury to said lacing-hook or without stopping the machine. This is accomplished by the construction hereinbefore described, the screw 36 being screwed into the plunger tight enough to hold the plate 33 against said plunger by frictional contact; but if a thick-headed lacinghook is being fed around by the feed-wheel the' plate 33 will be moved downwardly a sulficient distance to allow the lacing-hook to pass around the curved flange without injury,

and when the lacing-hook is set, as hereinafter described, against the anvil of the machine the plate will be forced upwardly against the shoulder 38.

The feed-wheel 35 is fast to a shaft 39, journaled to rotate in a bearing 40 at the bottom of the plunger 23. The shaft 39 has fast thereto a ratchet 41 and is intermittently rotated by means of a pawl-lever 42, pivotally supported upon-the shaft 39, having a pawl 43 pivotally attached thereto and engaging the teeth of the ratchet 41. The pawl 43 is kept in contact with the teeth of the ratchet 41 by means of a spring 44. A rocking motion is imparted to the pawl-lever 42 upon the shaft 39 bya cam-roll 45, journaled upon said pawl-lever and projecting into a cam-slot 46, provided in the plate 47, adjustably fastened by screws 48 to the frame 15 of the machine. The screws 48 pass through slots 49 in the plate 47, whereby said plate may be adjusted upwardly or downwardly, and thus vary the time at which the pawl-lever is rocked during the upward or downward motion of the plunger.

The lacing-hooks are fed by any appropriate mechanism Well known to those skilled in the art from the hopper 50 to a raceway 51. The raceway 51 consists of three plates 52, 53, and 54. The plate 52 is stationary and extends from an opening in the hopper 50 downwardly at an angle for a certain distance and then becoming vertical extends downwardly to the feed-wheel 35. The plate 53 is fast to a stationary portion of the machine and extends parallel to the plate 52 from the hopper to the point where said plate 52 becomes vertical. The plate 54 isa reciprocatory plate and is fastened to the plunger 23 parallel to the vertical portion of the stationary plate 52, a passage-way for the lacing-hooks being provided between the plates 52 and 53 and between the plates 52 and 54. The lacing-hooks, as hereinbefore set forth, pass from the hopper through the opening 55 down the stationary portion of the raceway to a separator-lever 56, pivoted upon a screw or stud 57, fast to the frame of the machine. The separator-lever 56 is formed in such a manner as to drop the lacing-hooks one by one as said separator-lever is rocked upon its pivot down the vertical portion of the raceway 51. The separator-lever 56 is rocked upon its pivot by a link 58, pivotally connected to a stud 59, fast to the plunger 23. Upon the same stud 59 is also pivoted a lever 60, having an arm 61 thereon connected by a spiral spring 62 to a screw 63, fast to the frame of the machine, and being provided with a segmental projection 64, all so arranged that when the plunger moves downwardly from its uppermost position, Fig. 4, to its lowermost position, Fig. 3, the feed-lever will be rocked upon its pivot 59 downwardly and across the path of the lacing-hooks upon the raceway 51, bringing the side 65 of the segmental projection 64 against the lacinghook cl upon the raceway and pressing said lacing-hook downwardly against the lacinghook 0, adjacent thereto, with a yielding pressure, as shown in Fig. 3. starts upwardly from the position shown in Fig. 3 after having set the lacing-hook a, in the stock the pawl-lever 42 will be rocked during the first part of said upward motion toward the right, Fig. 6, in the direction of the arrow in said figure, thus rotating the feed-wheel and bringing the lacing-hook 1) into the position formerly occupied by the lacing-hook a, the lacing-hook 0 into the position occupied by b, and the lacing-hook d into the position occupied by the lacing-hook c, Fig. 9. During this first part of the upward motion the feed-lever is held by the spring 62 with a yielding pressure against the lacing-hook d, so that said lacing-hook is held in a proper position to enter the recess (1, Fig. 9, as the feed-wheel 35 is rotated, as hereinbefore set forth. As soon as the plunger has been moved upwardly about one-half of its entire throw, bringing the cam-roll to the position indicated by dotted lines, Fig. 6, the rotation of the feed-wheel 35 will cease and the different parts-be-brought to the position shown in Fig. 10. I The' lacing-hook d will then be in the position of the lacing-hook c in Fig. 9, the lacing-hook c in the position of b, and the lacing-hook bin the position of a. At this point in the operation of the machine a stop-pin 66, fast to the feed-lever 60, abuts against the lower end of a stop-plate 67, fast to the frame 15, and upon the continued upward motion the feed-lever is rockedupon its pivotal stud 59 from the position shown in Fig. 10 to that shown in Fig. 4, thus moving the segmental projection 64 upon said lever out of the path of the lacinghooks upon the raceway and allowing the lacing-hook e to drop into the position occupied by the lacing-hook cl, Fig.4. During the hereinbefore-described upward motion of the plunger the separator-lever 56 is rocked by the link 58 from the position shown in Fig. 3 to that shown, respectively, in Figs. 10 and 4, dropping the lacing-hook e and allowing the lacing-hook f to descend to the position formerly occupied by thelacing-hook c, said lacing-hook eresting on the feed-lever projection 64,-Fig. 10, and then passing to the position occupied by the lacing-hook d in Fig. 4. Upon the downward movement of the plunger the pawl-lever is thrown from tho 1 position shown in Fig. 5 to that shown in Fig.

- to be taken by'the feed-wheel at the proper As the plunger pointviz., one of the recesses, as d, in the periphery of said feedand hence the feedin g of the lacing-hooks will be positive, which is a very essential feature in a machine of this class. Again, it will be seenand understood that as the lacinghooks above the separator-lever are dropped one by onedown the raceway to the position of the lacing-hook d,-Fig. 4, said lacing-hooks will not be pushed upwardly and downwardly by the reciprocatory motion of the'plate 54 of the racewayanother essential point in machines ofthis class, as it is very objectionable to have the lacing-hooks pushed up and down during the motion of the plunger, resulting in impairing the lacing-hooks and interfering with the practical feeding of the same along the raceway.

By the mechanism hereinbefore described for rocking the pawl-lever 42 I avoid excessive spring and wearing of parts such as are ordinarily used, in that the movable actuating parts are reduced to a singlecam-roll 45, which enters the cam-groove immediately adjacent to the ratchet, said cam-groove'being provided in the stationary plate and said stationary plate being readily adjustable to .obtain a slight variation in time of-throw of the ratchet by. means of the screws 48.

The lowermost lacing -'hook or is driven through the stock and clenched upon an anvil 68 in a manner well known to those skilled in the art. 7 I I The lacing-hooks may be fed from the hopper 50 to the raceway 51, as hereinbefore set forth, and delivered by any desirable mechanism well known to those skilled in the art. In the present machine I have illustrated this mechanism as consisting of a plate 69, provided with picker-arms 70, delivering .near

The operation of the machineas awhole is as follows: The lacing-hooks are placed in the hopper 50 and are fed out of'said hopper through-anopening 55therein by an intermittently-rotated picker-plate 69 onto the raceway 51, passing down said raceway between the stationary plates 52 and 53. Thence following the'stationary plate 52 downwardly between said plate 52 and the reciprocatory plate 54 thelowermost lacing-hook first comes to a stop against the periphery of. the separator-lever 56. Said lacing-hooks are'then dropped, as hereinbefore described by the rocking of the separator-lever 56 one by one to the lower part of the racewayradjacent to the feed-lever 60. Said feed-lever is rocked,

ing pressure until said lacing-hook is taken by the intermittently-rotated feed-wheel 35,

when it is carried step by step, as shown in Fig. 3, to a position directly above the anvil 68, where it is driven through the stock and clenched upon said anvil beneath the stock in 28 and 29.
