` SPECFliGATlON forming-part of Letters Patent N o. 729,524, dated June 2, 1903. Application filed January 17, 1902. Serial 110. 90.148. (Model.)

To @ZZ whom it' Irv/tty concern: I

Beit known that I, WILLAM P. BARTEL, a citizen of the United States, residing at Waltham, in the county of Middlesex and State of; Massachusetts, have invented new and useful Improvements in Machines for Setting Lacing-Hooks, of which the following is a speci-V tication. n This invention relates to machines for set ting lacing-hooks in the uppers of boots and shoes. I The object ofthe invention is io provide al` convenient, strong, simple, and durable machine which shall be capable of being runat,l a high Speed and efficiently feed the' lacing-I, hooks to the proper point above the center of the anvil and set the same in the upper of the boot or shoe.

The invention consistsinan improved raceway for guiding lacing-hooks from a feed-, hopper to a point above the anvil, said raceway being made of two plates located side by side, one straight edge of one of said plaies adjacent and parallel to one straight edge of the other of said plates, with a passage-Way provided betweenL Said edges for a lacinghook, one of`said plates being fastened to a stationary portion of the machine, and mechanism to impart a longitudinal reciprocatory movement to the other of said plates.

The invention, again, consists, in amachine' of the character described, of a reciprocatoryf plunger, a raceway comprising two plates located side by side in the same vertical plane, one of Said plates fast to astationary portion of the machine and the other to said reciprowheel journaled upon said plunger, and mechanism for imparting au intermittent rotary movement to said feed-wheel, in combination with a raceway-plate fast to a stationary portion ofthe machine, extending from said hopper-outlet to said feed-wheel and adapted to vguidefthe lacing-hooks from said hopper-outlet to said `feed-wheel, said raceway-plate lying ina vertical plane tangent to said feedwheel and parallel to the longitudinal median lineof said reciprocatory plunger.

mechanism for imparting an intermittent motion to a picker-arm.

The invention fu rther consists in the combination and arrangement Ot' parts Set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a front elevation Ot my improved machine for setting lacing-hooks, the hopper being partly brokenaway in order to disclose the interior mechanism. Fig. 2 is an end elevation of the same, taken from the left of Fig. l. Fig. 3 is a sectional elevation, partly broken away to Save space in the drawings, taken on line 3 3 of Fig. l, looking toward the left in said gure. Fig. 4 is adetail vertical section taken on line 4E 4 of Fig. 1 looking toward the right in said figure. Fig. 5 is a sectional elevation taken on line 5 5 of Fig. 2, the anvil-block being left in elevation. Fig. 6 is a side elevation, partly in section, taken from the same The invention also consists in an improved point ot' view as Fig. 3, of the raceway and plunger, anvil, and anvil-block, showing the plunger in its lowermostposition and the lacing-.hookv just inserted and clenched in the stock. Fig. 7 is a view similar to Fig. 6, showing the 'plunger partly raised. Fig. 8 is au `enlarged detail section taken on line 8 8 'of Fig. 3 looking toward the left in saidfig- IOO l ure. Fig. 9 is a perspective view of the guide and driver and the reciprocatory part of the raceway. Fig. 10 is a detail underneath plan of the raceway and centering-finger. Fig. 11 is a detail section taken on line 11 11 of Fig. 2. Fig. 12 is a detail front elevation of the knocker-lever. Fig. 13 is a detail section taken on line 13 13 of Fig. 2, showing the manner in which the two arms of the cam-1ever for raising and lowering the plunger are connected together. Fig. 14 is a detail section taken on line l5 15 of Fig. 2, looking toward the left and illustrating the relative location of the cross-pin and incline when the rocker-arm is raised. Fig. 15 is a detail elevation of the front of the hopper, viewed in the same direction as in Fig. 2, with a portion of the raceway by which the lacing-hooks are conducted from the opening in the hopper to the anvil.

Like reference characters refer to like parts throughout the several views ot` the drawings.

In the drawings, 20 is the frame of the machine, 21 the main driving-shaft, driven bya clutch-pulley 22 and having a pinion-gear 23 fast thereto and meshing into a gear 24, fast to the cam-shaft 25. The lacing-hooks are placed in the hopper 26, supported upon and rigidly fastened to the frame 20 of the machine.

In the interior of the hopper 26 is a picker 27, constructed in a manner well known to those skilled in the art, consisting of a hub 28, having six arms 29 fast thereto, said hub being fast to a shaft 30, journaled in a bearing 31 in said hopper and having an intermittent gear 32 fast to the outer end thereof. The intermittent gear is driven by an intel'- mittent pinion 33, fast to the cam-shaft 25. The intermittent pinion 33 has teeth 34 extending part way around its periphery, the remainder of said periphery being formed without teeth upon the pitch-circle of said pinion-gear. rThe said intermittent gear 32 has six concave locking-spaces 35,correspond ing to the number of picker-arms 29, said concave locking-spaces being formed to t the smooth portion of the periphery of the intermittent pinion-gear, whereby said intermittent gear is locked during the time taken for the smooth portion of said intermittent pinion-gear to rotate past said spaces. The lacing-hooks are picked up bythe arms 29 from the bottom ot' the hopper and delivered through the opening 36 in the front of said hopper and at the center thereof to the raceway 37.

The action of theinlermittent gearing, hereinbefore described, is particularly adapted to the intermittent rotation of the picker-arms in that it locks the picker-arms in a fixed position while the hooks are being delivered from said arms to the raceway and also causes a slight jarring of the same when each of the spaces 35 comes in contact with the smooth space upon the intermittent pinion-gear.

The raceway 37 is formed of three plates 38,

39, and 40. The plate 40 is fastened by screws 41 to a plate 60, fast, as hereinafter described, to a reciprocating plunger 42. Said plate 40 is also guided by a screw 43, fast to the head 44 and passing through a slot 45 in said plate 40. The plate 38 extends side by side with the reciprocatory plate 40 for a portion of its length and thence extends at an angle there from to connect with the hopper 26, said plate 38 being fast to the frame of the machine. The plate 30 is located above the portion of the plate 38 which extends at an angle from the reciprocatory plate to the hopper and is parallel thereto, said plate 39 being also fast to the frame of the machine. Between the plates 38 and 39 and between the vertical portion of the plate 38 and the reciprocatory plate 40 is provided a passage-way 46, down which the lacing-hooksslide, as shown in Figs. 3, 6, and 7.

The plunger 42 is arranged to slide in ways 47, formed in the'head 44 of the machine. The upper end of said plunger has a forked casting 48 fast thereto, provided with a pin 49, upon which is swiveled a sliding block 50, arranged to slide in a slot 51 in the arm 52 ot' the rock-lever 53. Said rock-lever has another arm, 54, fast to the arm 52 by a brace 55, and is rocked upon the pin 56 by a cam 57, which engages a roll 58 upon the arm 54. The guide and driver 59 is fastened to the lower end ot' the plunger 42 bya screw 90 and consists of a plate 60 and a curved iauge 61 integral therewith and extending at right angles to the face of the plate 6() across the periphery of an intermittently-rotated feedwheel 62. '[he feed-wheel 62 is provided with eight depressions 63 in the periphery thereof to receive the heads of the lacing-hooks a b c d, dac., and carry said lacing-hooks from a horizontal position to a vertical position, as shown in Fig. 8. The feed-wheel 62 is fast to a shaft 64, journaled in the lower end of the reciprocatory plunger 42; Said feedwheel and shaft 64 have an intermittent rotary motion imparted thereto by a ratchet 65, fast to said shaft 64 and rotated by a pawl 66, pivoted upon a pawllever 67, said lever arranged to rock freely upon the shaft 64 and held thereon by a washer 68 and screw 69. The pawl-lever 67 is connected by a link 70 to a lever 7l, pivoted at 72 to the hopper 26. Said lever 7l is provided with a cam-roll 73, which bears against a cam 74, fast to the camshaft 25. Said cam-roll is held against said cam by a pin 75, arranged to slide in the frame ot' the machine and held toward the right, Fig. l, bya spiral compression-spring 76.

To the under side of the plunger 42 is pivoted a centering finger 77, which is held sgainst the curved portion in the back of the neck of the lacing-hook by a flat spring 78. This device holds the lowermost lacing-hook a, Figs. 3 and 6, in a vertical position, and in combination with the feed-wheel 62 centers said lacing-hook about the center of the anvil IOO IOS

IIO

79. It has been found in practice that in a rnachine constructed as hereinbefore described the lacing-hooks will move up and down on the raceway 37 on account of the reciprocatory motion of said raceway and the plungerI by the next depression in the periphery of; said feed-wheel as it rotates in the direction of the arrow, Fig. 8. In order that the lacinghook may be held in the position shown, so

that it will enter the depression 63 as said` feed-wheel is rotated, I provide a separator lever 80, pivoted at 81 to the plunger 42 and provided with a cam-surface 82, which is held4 against a stationary pin 83 by aspring 84.

The pin 83 and spring 84 are both supported upon the stationary plate 38 of the raceway. As the plunger reciprocates, together with the plate 40 of the raceway, it is desirable that the lacing-hooks upon said raceway should.

not all of them be pushed up and down by said reciprocatory motion, and to overcomev this a spring-stop 85 is provided, fastened by a screw 86 to'the head of the machine and the upper end 87 of said spring-stop standing normally across the path of the hooks upon the raceway. Said spring-stop is thrown toward the left, Figs.v 6 and 7, bya pin88, fast to the reciprocatory raceway 40, said pin 88 encountering the bend 89 in said spring-stop during its upward motionand thus moving said spring-stop to the left from theposition shown in Figs. 6 and 7 to that shown in Fig. 3.

In order to prevent the lacing-hooks from lagging upon the arms of the picker when said arms are in position to deliver the lacing-hooks to the raceway and also to prevent said lacing-hooks from lagging upon the raceway, I pro-vide a knocker 91, Fig. Il, consisting of a pin 92, arranged to slide in a hole 93, formed transversely of the arm 52 of the rocklever 53 and having ils end normally held against the cover 94 of the hopper by a spiral compression-spring 95. The pin 92 has a `cross pin 96 fastv thereto and projecting through a slot 97 in the boss 108 upon the armv figure, tipping the same upon its pivot 100.`

When the arm 52 has arrived at its lowermost positionythe pin'96 clears the under sidev of the incline 98, and the spring 102 carries saidspring-dog to the right, Fig. 1. Now vas the arm 52 rises the pin 96 encounters the opposite side of the incline; but as said incline is stationary, the dog being held against any further motion toward the right by a screw 103, screw-threaded into the bracket 101 and the lower end thereof bearing against a boss 104, formed upon the spring-dog 99, it follows that the pin 96 will be forced to the left, Fig. 1, compressing the spring 95 and drawing the pin 92 also to the left in said gure until the arm 52 is moved upwardly to a sufficient extent to allow the pin 96 to clear the upper end of the incline 98, when the spring 95 will expand and the pin 92 will be driven against the face of the hopper-cover 94, giving the same a sharp blow, which will jar the lacing-hooks both on the picker-arms and on the raceway. Y

The operation of the machine hereinbefore described is as follows: The lacing-hooks in the hopper 26 are carried upwardly by the picker-arms from the bottom of said hopper and delivered in a manner well known to those skilled in the art through the opening 36 to the stationary portion of the raceway 37. Said picker-arms are rotated by the intermittent gear 32 and pinion 33. The hooks descend the raceway between the Stationary plates 38 and 39 thereof and thence downthe Vertical passage-way between the stationary plate 38 and the reciprocatory plate 40 of said raceway. Assuming the raceway to be filled and three of the depressions 63 inv the feedwheel 62 to have a lacing-hook therein, as shown in Fig. 8, the lowermost lacing-hook a., the next, b, and the next, c, each being held in a depression in the feed-wheel 62, the other lacing-hooks on the raceway above c beingd t 62 is'given a one-eighth rotation by the pawland ratchet mechanism hereinbefore described, said pawl-and-ratchet mechanism being operated by the link 70, cam-lever 71,-and cam 74,@arrying the lacing-hookato the right,

lacing-hook is fastened, and feeding the lacing-hooks b and c from the position shown in Fig. 8 to that shown in Fig. 7, b taking the relative position of the lacing-hook a and c that of b. The lacing-hook d is carried by the next approaching depression 63 upon the feedwheel 62 from the position shown in Fig. 8 to the position ofthe lacing-hook c shown in said figure. As the plungery 42 moves from IOO IIO

Fig. 8, together with the stock to which said the position shown in Fig. 6 to that shown in `v Fig. 7 it will be seen that the separator-lever 8O tips upon its pivot by reason of the shape of the cam-surface 82, the upper portion of said lever being thrown toward the right in said Fig. 7 and bringing the pointed end 106 over the lacing-hook e after said lacing-hook has passed downwardly, which it is enabled to do by reason of the lacing-hooks d, c, b, and a having been fed forward one space by the feed-wheel, as hereinbefore set forth. The separator-lever 8O thus holds the lacing-hook e in the position shown in Fig. 7 and corresponding to that occupied by the lacing-hook d in Fig. 8, so that upon the next partial rotation of the feed-wheel said lacing-hook e will be in position to be taken by the next approaching depression in the periphery of the feed-wheel. As the plunger 48 continues its upward motion from the position shown in Fig. 7 to that shown in Fig. 3 the pin 88 encounters the bend 89 in the spring-stop 85 and moves the same to the left from the position shown in Fig. 7 to the position shown in Fig. 3, thus removing the end 87 of said spring-stop from its position across the path of the lacing-hooks and allowing the lacinghook p, Fig. 7, to descend with the lacinghooks o n, &c., upon the next downward motion of the plunger and of the raceway 40. The lacing-hooks q r and the other lacinghooks upon the stationary portion of the raceway descend the space of one hook and are supported upon the end 87 of the spring-stop 85 until the next upward motion of the plunger releases the lacing-hook q.

The feed-wheel 62 is locked in position by a spring-stop 107 in the plunger 42, Fig. 4.

It will be seen and noted that the plate 38 is tangent to the feed-wheel 62 and extends from said feed-wheel to the hopper-outlet 36, forming a continuous unbroken guide fastened to a stationary portion of the machine from said hopper-outlet to said rotatory feedwheel, and also that the raceway-plate 40 is tangent to said feed-wheel and extends upwardly therefrom adjacent and parallel to said stationary plate 38, the edges of said raceway-plates being separated laterally from each other to form a passage-way for the lacing-hook.
