WIRE-ROLLING AND CUTTING DEVICE.

Specification of Letters Patent.

Patented Feb. 1,1921.

Application filed October 15, 1919. Serial No. 330,737.

To all whom it may concern:

Be it known that I, ALEX Srinnrrrls, a citizen of Russia, residing at Chicago, county of Cook, and State of 1llinois,have invented certain new and useful Improvements in Vi ire Rolling and Cutting Devices, of which the following is a specification.

This invention relates to a wire winding and cutting machine andit has for an object to provide a simple andeasily constructed and operated device whereby wire coming from drawing dies or otherwise may be rolled upon a suitable spool. or bobbin and separated from the main length.

Other objects relate to the provision of means for grippingthe main length of wire andholding it in position after being out, and to the provision of a novel form of cutting means and a novel mounting for the spool permitting its ready withdrawal when full. a

.For further comprehension of the inven tion, andof the objects and advantages there of, reference will be had, to the following description and accompanying drawings, and to the appended claims in which the various novel features oi the invention are more particularly set forth.

Figure l ofth drawings is a plan Vl&\V

of awire windingand cutting machine con structed according to my invention.

The frame of my improved inac fii here shown comprises a flat base 1 of oblong shape from-which an integralplate-lilre member QeXtends upward, this ,lnen berhavng an angularoi'fset'fi at one end. Forconveniencel shall hereinafter'refer tothe nieniber2, which carries nost of the operating.

parts, simply as the plate.

1 1s a s de elevation, partly inflongi- Journaled upon plate 2 ina vertical row and near theend thereof oppositetothe offset 3,,isaseries of horizontal stub shaftsfi, upon whlch the spools. 5 are sliolablyfn ount e VYhIIBthB shafts project a distance approximately double the length of the spools to accommodate the back and forwardinovement of the spools as the wire winds thereon. The spools 5, each have a sleeve 6 mounted therein and slidable on theshait 4, the latter being longitudinally grooved'as at 7, while the sleeve is slotted and pressed inwardly on one side to form a key 8, engaging in this groove. A flat spring 9, is fixed at one end in the key 8, a'ncl'its opposite end has a projection 10 which extends partly acrossthe outer face oithe spool and prevents displacement of the latter.

These stub-shafts 4, are rotated in unison b means of a crankhandlell on a gear 12 pivoted on the plate 2, and meshing with an idler pinion 13 whichmeshes in turn witha second gear l/lon the end of one of the stub shafts,the gear '14 having. eccentrieally connected thereto as at 15 a connectingrod .16 which also connects withcrank arms 17 on the ends of the other stub shafts a.

The wires to be wound are indicated at 18 and are led to theniachine through aper tures 19, in the offset 3 and then between grip- I ping devices which are arranged one "above the other and with a common operating Iiieans to act in unison upon all the wires. These ripping devices each consist ofa disk QOfixd on the, upper endof apin 21 slidable in a head 22 on the end of a lever arm 23 fulcrumed as at 24511 on studs 25 projecting from the plate "2. spring 26 surrounds each pinQlhetween 1the1disk20 and head'22 and normally acts to press the disk upward. These disks cooperate with abutment heads 2Tfixed on the plate.

The opposite ends of 1evers23 project thronghslots28in plate Qand are. ivotally connected to a vertical link 29 whih is normally pressed upwardlyby a spring 30 which bears betweenthebase 1 and the lower end of thelink 2Q. springcateh '32 having a beveledupper faee33 anda handle 34 is hired on thebase 1 and is adapted to automatically engage the projection 31 onthe' link when the link is depressed to operatethe grippers'a common operating handle for the grippers and cutters being provided, as will be presently pointed out.

The cutters are arranged on plate 2 a short distance from the grippers just described and comprise fixed knife blades 35 formed on a vertical bar 36 secured to lugs 37 projecting from the plate 2 and having downwardly inclined cutting faces 38. Coiiperating with these fixed knives are the movable knives 39 pivoted as at 40 to projection 41 from the plate 2 and having rigidly connected thereto the arms 42 which project through slots 43 in theplate 2 and are pivoted to a link 44, similar to the link 36, at their ends. This link 44 is also normally pressed upwardly by a spring 45 which bears against the lower end thereof, a spring catch 47 similar to the catch 32, being adapted to engage a projection 46 on the link when the link is depressed.

Pivoted to the lug 37 to which the knife bar 36 is fastened at its upper end is a handle 48, this handle passing through an open ing 49 in the plate 2. This handle is located between the gripping and cutting devices and is provided with the oppositely projecting angular fingers 50 and 51 which are adapted to engage the upper ends of the respective links 29 and 44 to operate the gripping and cutting devices.

Mounted on studs 52 projecting from the plate 2 adjacent the cutting devices are a series of grooved rollers 53 over which the wires pass. A pair of cooperating friction straps 54 and 55 are mounted upon the plate 2 adjacent the rollers 53 and serve to hold a tension on the wires, these strips being preferably spring-pressed toward each other, in any suitable manner.

' The manner of operation of my improved 7 .wire winding and cutting machine is as 40 follows": 7.

v The wires are led through the openings 19, passing between the fixed and movable mem bers of the grippers, and of the cutters, then over the rollers 53 and between the tension straps 54 and 55 to the spools 5 to which the ends may be secured in any suitable manner. 1' The spools arethen rotated to wind the wires thereon by turning erank'handle 11 and rotating gear 12, pinion 13 and gear 14, the connecting rod 16 causing all the shafts '4, and the spools mounted thereon, to rotate. Whenthe spools are'wound full. the handle 48'is depressed, throwing links 29 and 44. downward and causing the knife blades 39 and gripping disks 20 to move upward, simultaneously severing the wires and gripping the ends thereof. As the links 29v and 44 descend the catches 32 and 47 engageover the projections3l and 46, holding the-knives and gripping disks in operativeposition. After'the spools are removed and new ones placed on the shafts 4 the catches are released and the operation as just described repeated.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:
