WARREN r. FRASER, OF

DORCHESTER, MASSACHUSETTS.

DEVICE FOR FEEDING LACING-HObKS AND THE LIKE.

T on whom it may concern:

Be it known that I, \VARREN F. FRASER, a subject of King Edward VII, residing at Dorchester, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Devices for Feeding Laeing-liooks and the Like, of

which the following is a specification.

This invention relates to a device for sepfo arating lacing-hooks or the like from a mass of the same contained in a ho mm and. feeding the same to a raceway leading out of said hopper to any desired point in a machine whcre'they may be driven and clenched in 1 5 sheet material.

The object of the invention is to provide a device of the character set forth which will separate a large number of lacing-hooks per minute from the mass of lacing-hooks con- 0 tained in the ho )por andfeed them to the raceway, the mechanism b which the lacinghooks are taken from the hopper and fed to the raceway being capable of continuous rotation and the raceway so constructed and 5 arranged with relation to the picker-blade,

by which the lacing-hooks are taken from the hopper and carried to the raceway, that hooks can feedonto the raceway from the picker-blade while the picker-blade is rotating.

The invention consists in the combination and arrangement of parts set forth in the fol lowing specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a side elevation of my improved device for feeding lacing-hooks. Fig. 2 is a central longitudinal vertical section, partly in elevation, of the same. Fig. 3 is an enlarged detail section, part1 in elevation, taken on line 3 3 of Fig. 1 100 ing toward the left in said figure,

illustrating the position of a laeing hook on the raceway. Fig. 4 is a section of the hop per, with the raceway and bottom of the hopper shown in plan, the sectional portion being taken on line 4 4 of Fig. 2. Fig. 5 is an enlarged section, partly in elevation, taken on line 5 5 of Fig. 4 looking in the direction'of the arrow in said Fig. 4 and illustrating a porvtion of one of the picker-blades with lacinghooks thereon which are in position to slide dqwnwa'rdly therefrom upon the raceway t e hopper being shown broken away in said v ts w tosave space in the drawings. Fig. 6 is als tr ting one of the picker-blades moved for Specification of Letters Patent.

etional elevation similar to Fig. 5, illus- Patented Aug. 14,- 1906 ward slightly from the position shown in Fig. 5 and illustrating how the lacing-hooks which are on the picker-blade are carried back into the hopper when the raceway is filled. Fig. 7 is another illustrative view similar to Figs. 5 and 6, illustrating the raceway filled with lacing-hooks and the end of one of the pickerblades passing over that portion of the raceway upon which the lacing-hooks are located. Fig. 8 is a section, partly in elevation, taken on line 8 8 of Fig. 5 looking toward the right in said figure. Fig. 9 is a section, partly in elevation,taken on line 9 9 of Fig. 5 looking toward the right in said figure.- Fig. 10 is an underneath plan View of the rotary picker. Fig. 11 is a front elevation of said rotary picker.

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

In the drawings, 12 is a bracket adapted to be fastened to the frame of the machine. 13 is a hopper rigidly fastened to said bracket 12 and consisting of a hollow casing 14, having a cylindrical bore and a bottom 15. The hopper 13 is fastened. totlresbracket 12, so that the bottom thereof standsat an angle. A slraft 16 is'journaled to rotate in a bearing 17, forming a portion of said hopper, and pro jects therethrough, a pulley 18 beingfa'stened to the lower end of said shaft and the picker 19, fast to the upper end of said shaft.

The picker 19 consists of a hub 20, with arms 21 21 extending radially outward therefrom and connected together at their outer ends by a rim 22. The rim 22 has three blades 23 23 fast thereto, said blades being formed concentric with the picker 19 or with the median axial line thereof, the front edge 24 of each of said blades being formed upon a helical curve. The lower edge 25 of each of the blades 23 projects into an annular groove 26, Fig. 4, which extends partly aroundithe bottom of the hopper 13. The lower edge 25 of each of the blades 23 projects into the groove 26 as the picker is being rotated. A portion, however, of the bottom of said hopper is cut away to form a depression 27.

f lhe raceway 28 isjformed in two parts-a lowerportion29 and an u per portion 30. The lower portion 29 exten s for a part of its lengththat is, from a to b, Fig. 4-on a curve concentric with the interior of the hopas they are rotated in the operation of the machine. The lower portion 29 of said raceway extends from the curved. portion a b thereof and from the point a, outwardly through a hole 31, provided in the periphery of the hopper at the bottom thereof. The upper edge oftlre raceway extends downwardly from the point a. of said raceway as the raceway passes through the oper ing 31, beneath the plane in which the upper edge of the curved portion a b of said raceway is located.

The upper portion 30 ofthe raceway '28 is preferably located at one side of said raceway, as illustrated in Fig. 8, so that said upper portion bears against the shanks of the lacing-hooks 32, located upon the lower portion '29. Said upper portion 30 of the raceway terminates in a curve 33 at its uppermost end, which extends upwardly in order to prevent any clogging of the lacing-hooks.

The operation of the device is as follows: The lacing-hooks are placed in a mass in the interior of the hopper 13 and the picker 19 rotated by means of the pulley 1S and shaft 16. As the ditl'erent blades 23 of the picker pass through the mass of lacing-hooks at the ower end of the hopper some of these lacinghooks are separated from the mass and are carried by the picker-blades upwardly away from the mass of lacing-hooks, said lacing hooks resting on the front edge of the pickerblade with the heads located in the space between the picker-blade and the interior of the hopper-casing 14, the shanks projecting toward the center of said hop er. As soon as each picker-blade arrives a ove the curved portion a b of the raceway the lacing-hooks slide off the picker-blade andonto the raceway. Said raceway being at an angle, these lacing-hooks slide down the raceway on the lower portion 29 thereof, out through the opening 31, and downwardly along the raceway to the point in the machine to which it is desired that they shall be uided. j

In Fig. 5 the picker-blade is illustrated with the point thereof at the end a of the curved portion a b of said raceway, with the raceway full of lacing-hooks, and as the icker-blade is rotated it will be seen that the acing-hooks upon the picker-blade cannot slide therefrom onto the ractnvay,,but will be carried past the raceway at the downwardlycurved portion of its upper edge and will then slide off the; picker-blade into the hop er. The lbwermost lacing-hook upon the pic-iterblade will be tipped, as illustrated in Fig. 6 at 32, and carried back into the hop )er by the oint of the picker-blade, which wii owerinost lacing-hook across the, lacing-hook 32 adjacent thereto and finally drop the sameinto the hopper in the recessed portion 27 thereof. As t ie curved'portion from uto b of the raceway part 29 is in ahneinent with the picker-blade as it passes thereover, it will be seen that saidpicker-blade forms, in ell'cct,

l drag this a continuation of the raceway, so that the 'moment the picker-blade arrives at the point b the lacing-hooks on the picker-blade can begin to slide ofi' onto the curved portion of the raceway, down said raceway, and out of the hopper. Therefore on account of this construction the picker can be continuously rotated instead of intermittently rotated. as

r in devices heretofore constructed, and, moreover, when the raceway is tilled, as illustrate in Figs. 6 and 7, the continuous rotation of the picker-blade does not injure the books on the raceway, neither is the continuous rotation of said pickenblades blocked or interfered with by the lacing-hooks which stand upon the raceway, the same being pushed out otthc way, as illustrated in Fig. (5, leav ing the raceway full and allowing the blade to pass over the uppermost lacing-hook 32 located. thereon Having thus described my invention, what I claim. and desire by Letters Patent to cure, is
