STRANDINGr-MACHINE.

NOS. 1,043,800, 1,043,897 mi 1,043,898 for uniting hooked links and perforated plates.

The main object of the present invention is to provide a construction in which the plates may be automatically supplied from a hopper and connected up with the linksk to form a continuous strand or chain.

Other objects are to improve the details of the mechanism to facilitate theoperation and adjustment.

in the preferred form, as illustrated, a quantity of perforated plates is placed in a rotating hopper which keeps a vertical guide supplied with the plates in an orderly arrangement. Hooked links are supplied on a guide adjacent the plate guide. The links are intermittently fed from the bottom of the link guide and the rear hook engages in one of the apertures in the plate in the bottom of the plate guide.V The'strand is intermittently drawn through a horizontal at right angles .trom the base or" the plate guide. operation, the front hook of thev next link engages in the rear aperture of the first mentioned plate at the same time that the rear hook engages in the aperture of the succeeding plate.

The bottom plate is yieldingly supported so that as the strand is pulled or drawn along, the plate is allowed to turn diagoplate along the horizontal strand guide.

The strand guide, draw-out mechanism and tension mechanism may be constructed generally as indicated in the Bigelow Patents No. 1,043,896 or N0. 1,043,898.

The apertured or perforated plates 10 are usually square and provided with holes in each'corner. These are supplied in a vertical grooved guide 11. This guide is kept iilled vtrom a hopper 12, having an entrance 12. This hopper is carried on a shaft 13, which is continuously rotated in any suitable manner.

The hopper is conical in shape and its larger end abuts against a plate 14, which forms a closure. The larger end of the hopper is provided with a plurality of recesses 15 adapted to admit individual plates. Projections 17 between the recesses 15 serve to move the plates as the hopper rotates in the direction of the arrow or'vFig. 4.-. The flange 1G supports the plates and guides them to the top of the guide 11. A. spring` 18 serves to yieldingly hold the plate, which is just emerging from behind the base of the hopper at the top of the guide 11. llVhen the guide 11 is filled up, plates which subflange 20 and the abutment 14. On account .y

'of the shape of the hopper and the arrangement of this flange, the movement of the hopper keeps the plates tumbling over each other and fallingtoward the flange 20, and some of these plates fall over the flange and down into the recesses 15, whence they are m'oved to the top of the? guide 11.

l At the bottom of the guide 11 is a movable support 21 hinged at 22 and drawn yieldingly upward by a spring 23 'against a stop 24 at or near the lower end of the guide-l1; This supporty is grooved to it the edge of one of the plates,a.s indicated at 25. A lateral support 26 assists in positioning the lower edge of the plate .and theoverhanging nose 27 assists in holding the upper edge ofthe plate. i

The partially hookedv links 30 are supplied on a guide 31, whichis secured-toy a stationary member 32 by means of Aclamping bolts 33, which permit the lateral adjustment of the link guide relative to the plate guide. f

The links on the guide 31. kare supported by a yielding member 34 adapted to be moved inwardV by a pair of cut-off knives 35,

l,as indicated4v in my former application #874,595 When the knife 35 moves the support 34 inward, it releases the bottom link on the guide and allows it to fall on the feed plunger 36., In the next stroke of the feed plunger 36, the link falls upon the flanges 37, which are immediately vbelow thefeedplunger andrwhich support the link on theplane of the front edge of the plunger. The flanges 38 extend overlthe flanges 37, so as to allow'the plunger 36 to operate beneath the guide 31, 4but vso as to hold the ends of the link and prevent them from tilting. Y The links are further positioned by the stationary members 31. The feed plunger V.36,and the cut-offv knives 35 :are carried by a slide. 40 operated by a cam` 41 on the shaft 42. ;The flanges 37 and 38 are carried by dies 39, 39. .Dies 43 and A,faces, as indicated by the dotted lines in Fig. 2, co-actfwith the hooked ends ofthe links, as the links are fed forward 1by `the v plunger 36, to partially close or bend the hooks.

The. horizontal grooved dies 39, 39 are .Y shaped at the ends `to cause theends30,302

ofthe link to be bent over as the ends pass through the apertures in theI plates 10', 102. The die 44 is carried by a lholder 47, andl is horizontally adjustable along the guides45,

46 so as to bring it into its properposition for Vlinks yof different lengths.. The, die 43 and the'holder 47 are bot-h carried bya slide 48 operated bythe cam 49 on the shaft` 5() andareoadjustable towardand from the strand guide 45. The, completion of Vthe closing movement of the :hooks is performed by dies 51 51 on a holder 52 on the slide 48.` The holder is adjustable' toward and grooved on their forward being` from the strand guide and the dies 51 51 are adjustable along the strand guide to accommodate links of different lengths. The body of the link is supported opposite dies 51 51 by die 39 and a plate is held adj acent one die 51"byv a vfork 53 carried'by slide 54 operated bycam 55 on the shaft 42. An auxiliary strand support 56 is adjust- 'able'onthe guide 45 for holding and guiding the strand adjacent the die 51, but this may be omitted. Y lThe strand `is intermittently pulled along The .shafts '42 and .G3 are connected by miter gears 66.q Theshafts 50 and 63'are connected: by .miter v.gears 67.. l Y j 1n the operatioiuof the mechanism,the guide 11y is continuously kept-,filled with the perforated plates, Vby the action'of the hop-,l

per 12.v The 'bottom plate 10,is supported by thel yielding member l21. 'Theplate 102 is suitably supported in, the strandguide and the hooked link fed forward so. asto en- -gagein apertures ofthe plates-as indicated in Fig. 5. The hooks 30 and 302y arei bent over by. dies 39, 39, 43 .and 44,z as the link is fed forward bythe strand is drawn along intermittently,the plate 10 is tiltedaip, axes are vertical and horizontal, respectively.
