T 0 all whom it may concern:

Be it known that we, WILLIAM P. BARTEL and SYDNEY E. TAFT, residing at, respectively, l/Valtham and South Framingham, both in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Hook-Separating Mechanism, of which the following is a specification.

This invention relates to devices for separating lacing hooks and the like from a 4 quantity 'of the same contained in a hopper and feeding the lacing hooks or like articles thus se arated to a raceway, down which they slide, said lacing hooks being subsequentlyfed one byone by suitable mechanism, to be driven and clenched by other suitable mechanism in sheet material, such as the uppers of bootsand shoes.

The device for separating the lacing hooks,

. as hercinbefore set forth, consists of a rotary picker-plate, well known to those skilled in the art, to which an intermittent rotary-mo- I tion is imparted whereby the lacing hooks are picked up upon the different blades of the picker plate during the rotary motion of said picker. plate and while the picker-plate is stationary these lacing hooks slide off the blades of the icker-plate onto the raceway. In devices of din I picker-plate in its forward motion between its through the middle part of its movements in? crease its speed, and finally come to astop slowly. In other words, said picker-plate has an intermittent differential rotary movement imparted thereto and in order that the consecutive movements of the picker plate may be separated one from the other by as slight a sirable t at the mechanism which feeds said picker-plate shall not only be capable of imparting the slow differential forward rotary movement, hereinbefore set forth, to said plate, but that in its return movement said" ckly. Indevices of the character. hereinbefore set forth, it is also. desirable that when the raceway has been filled with hooks, the mechanism for feeding the hooks from the or to, the raceway, viz., the picker-plate in t s instance, should be stopped while the machine to which it is attached containing the driving and setting mechanisms shoul 4 mechanism shall be moved very qui hop .easi y 0 quickly 's class it is desirable that the periods of rest'should start slowly, then eriod of time -as possible, it is de-.

' Fig. 2is a sectiom-part continue its operation. Otherwise, when the raceway becomes filled the lacing hooks will be carried around by the picker-plate and emptied into the hopper again as the;

blades escend during their rotary motion and the continual movement 'ofthe pickerplate through the lacing hooks at the bottom of the hopper tends to injure the lacing hooks and remove more'or less japan from the surface thereof. It is, therefore, desirable that the picker-plate shall only be rotatedsufficiently to kee the raceway well supplied with lacing hoo s The object ofthis invention, therefore,'is to -rovide a cheap, simple, durable and eratcd mechanism which will imparta s to the picker-plate'and without moving said pickerp and, further, the object of thisinventlon is to provide a mechanism for driving said picker-plate operating -mechanis'm which may be readily disconnected therefrom, thus which will return In chanism stationary when the raceway is fil ed-withhooks, as hereinbefore described.

ow intermittent rotary movement I leaving said picker-plate and its driving The invention consists in the'combination.

and arrangement of parts set forth in the following specification and. particularly pointed out in the claims thereof.

In the drawings I have illustratd my improved lacing hook separating'and feeding mechanism as attached to the: frame of a lacing hook setting machine and driven by a pulley loosely mounted upon the. main driv' mg shaft of said lacing hook setting machine. Referring to the drawings: Figure 1 is a of my improved mechanismfor plan view separating and feeding lacing hooks and the like, together with a, portion of the frame of a lacing hook setting machine upon which said separating and feeding mechanism is supported, the main driving shaft of said lacing hook 'setting machine-and driving pulley therefor, said driving shaft being roken away to save s ace in the drawings. y in elevation, taken on line 2 '2 of Fig. 3, looking toward the right in said figure. tion of the parts illustrated-in Fig. 1, the frame of -the lacijng hook'setting machine being broken away to save spacein the a detail front elevation drawings. Fig. 41s of the hopper and raceway, the picker-plate Fig 3 is a side elevabeing indicated by dotted'lin'e's and the raceway and hopper being broken away to save space in the drawings. 7 Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 6 is a "hopper of well known construction, which is fastened to the frame ,7 of alacing hook setting .machine,

, Afrotary picker-plate 8 is arranged to rotate L5 Within an annular recess' 10 provided in said hopper adjacent to the cover 6 thereof and is constructed with-a plurality 'of radial arms .8, 8. A shaft 9 is journaled to rotate in a bearing 11 in said hopper and has rigldly 8 and at the opposite end thereoffrom that to which said picker-plate is attached a ratchet 12 is fastened. A lever 13 is jour naled to rock loosely upon the picker shaft- Said lever 13 20, 9 adjacent tothe ratchet 12.

has a pawl 14 pivoted thereto which engages the ratchet I2 and is provided'with a slot 15 extending longitudinally thereof upon the 'opposite side of the shaft from that upon tion isjm'p'arted to the lever 13 by a crankarm 16, and crank-pin 17, 'said crank-pin rojecting into the slot 15 in said lever 13.

he crank-arm 16 is fast to a crank-shaftdS journaled to rotate in a bracket 19 fast to the frame 7. A rotary motion is imparted to the crank-shaft 18 by ,a pulley 20 fast thereto and driven by a belt 21, which, in turn, is driven by a pulley 22 fast to an intermediate 5 shaft 23 (Figs. 2 and 3). The intermediate shaft 23 is journaled to rotate in a bearing provided in the interior of the gear 24 and its hub x The gear 24 is locked, when desired, to the intermediate shaft 23 by a friction clutch 26, consisting of two members, one of said members being a disk 27 provided upon its periphery with a conical friction surface 28 which engages a conical friction surface 29 provided upon the interior of the gear'24.

A spiral spring 30 bears at one end thereof against the hub of the pulley 22 and at the other end thereof against a shoulder 31 formed upon the interior of the gear 24. Thehub 25 has provided at the left hand end thereof (Fig. 2) an annular flange 33 which bears against. a bracket 34 fast to the frame 7. The'hub 25 of the gear 24 is journaled to rotate in a. bearing 35 provided in said bracket 34. Rotary motion is imparted to the gear 24 by a gear 36 fast to a pulley 37 journaled to rotate loosely upon themain driving shaft 38 of the lacing hook setting machine, said main driving shaft being j our- 0 naled to rotate in a bearing 39 on said frame.

frame 7 and has a vertical arm 42 extending upwardlyfrom said pivot adjacent to the left hand face (Fig. 2) of the pulley 22. Said 5 lever has a horizontal arm-43 by means of attached to one end thereof the picker plate which said pawl is located. aA rocking mo- A clutch lever 40 is pivoted at 41 to the the disk 27, intermediate saft 23 and pulley the spring 30 with its friction surfaces 28 and =29 in contact one with the other, but when it seams which it ma be operated,e1ther -by hand,

or, if referred, may be connected with a suitab e ,treadle and operated by foot power. The friction clutch 26 is normally held by the frame 7 (Fig. 3), said dog being rotated upion itspivot out of contact with the arm 43 35 w en it is desired'to rock the lever 40 to release the pulley 22 and allow the frictional surfaces of the clutch to be brought into contact b the spiral spring 30, or into the posi- 'tion illiistrated in Fig. 2.

The operation of the mechanism hereinbefore specifically described is as follows: Assuming the necessary amount of lacing hooksto be placed within the hopper 6 and the clutch 26 to be in operative position, as

' illustrated in Fig. 2, the main driving pulley 37 'impartsa rotary motion to the gear 36 which, in turn rotates the gear 24, thus rotating the disk 27, intermediate shaft 23 and pulley 22. The pulley 22 drives the belt 21, thus rotating the pulley 20 in the direction of the arrow (Fig. 3). The pulley 20 rotates the crank-shaft 18, crank-arm16 and crankpin 17 in the direction of the arrow (Fig. 3). As the crank-arm 16 and crank-pin 17 are thus rotated in the direction of the arrow (Fig. 3) it will be seen that said crank-pin will travel longitudinally of the slot 15 toward and away from the picker-shaft 9, which con- 7 stitutes the pivot of the pawl-lever 13, so 1 0 that duringone portion. of the rotation of said crank-arm and crank-pin, said crankpin will be nearer the pivotal center of the pawl-leverthan at another time, and by' reference to Fig. 3 it will be seen that when the crank-pin is farthest removedfrom the pivotal center of the pawl-lever 13, said lever is beingmoved in a direction" to rotate the picker-plate throu h the pawl 14, ratchet 12 and. shaft 9, and w ensaid craiik-pin is pass: ing through that portion of its rotation-which brings it nearest to the pivotal center of the pawl-lever said pawl-lever is being moved backwardly or in the direction to carry the pawl backwardly from one tooth of the ratchet to engage a new tooth thereon, so

that it will be evident that a slow forward and quick return movement is imparted to the pawl, and further at eachend of the movement of the pawl during the beginning of its forward movement and during the end of said forward movement, and also at the beginning of its return movement and the end of its return movement, said pawl will travel slower than in the middle of either of said movements, for the reason that at such times the crank-arm is in a position similar to that illustrated in Fig. 3, so that it is traveling longitudinally of the slot 15 without moving the pawl-lever to any more than the slightest extent. In other words, the median longitudinal line of said slot is tangent at such times to a circle described by p the center of the crank-pin 17.

As the picker-plate is rotated, as hereinbefore described, lacing hooks are carried by the arms 8, 8 of said picker-plate in the.

bottom of the hopper upwardly and slide along the upper surface of said arms, said lacing hooks passing outwardly through a suitable orifice in the sideof the hopper onto the raceway 46 and slide downwardly upon said raceway to the driving and setting mechanism in a manner well known to those skilled in this art. When the raceway becomes filled the operator rocks the clutch leverat) upon its pivot to disconnect the members of the clutch 26, as hereinbefore described, thus disconnecting the mechanism which drives the pulley-operating me'ch anism therefrom and stopping the rotation of the picker-plate.

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

1. In a device of the character described, a hopper, a picker plate journaled to rotate within said hopper, mechanism adapted to impart an intermittent rotary motion to said picker plate, said mechanism adapted to im part a slow forward motion to said picker plate and to return preparatory to imparting another forward movement to said picker plate at a relatively rapid; rate of speed,
