SPUR-WHEEL FENCE-WIRE TWISTING AND SPOOLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 373,457, dated November 22, 1887.

(No model.)

To all whom. it may concern:

Be it known that I, CHRIsTIAN C. HILL, a citizen of the United States, residing in Chicago, in the count-y of Cook and State of Illinois, haveinvented anew and useful Improvement in Spur-Vheel Fence-Wire Twisting and Spooling Machines, of which the following is a specification.

The object of my invention is to provide a machine of a simple and cheap construction for twisting and spooling spur-wheel fencewires or other filaments.

My invention consists in the novel devices and novel combinations of devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, and in which similar letters of referenceindicate like parts,Fig ure lis a plan view of a device embodying my invention. Fig. 2 is a side elevation. Figs. 8 and 4 are central longitudinal sections showing the spindles or bearings of the twisterframe, and Fig. 5 shows a modification.

In said drawings, A A represent the frame or standards upon which the twister-frame B is mounted or journaled. The twister-frame B is cast with a large hollow spindle, B', at one end, having a channel or groove, b, for the bearings b' b to fit in. The cap or upper bearing-block b is preferably of wood, and is secured in place by long bolts b2. Through the opening in this hollow spindle B the wire or wires to be spooled or twisted and spooled 35 pass, and the opening should be large enough to permit the wire or wires to be inclined by the guiding device from one end of the spool to the other without causing the wires or the spur-wheels thereon to strike against the inside of said hollow spindle. In practice, I ordinarily make the hollow spindle about eight inches in diameter for twisting and spooling spur-wheel fencing or barbed wires, the spools for which are ordinarily about one foot in length. The size of the hollow spindle may, however, be greatly varied. The twister-frame is also provided or cast with a smaller hollow spindle, B2, at its opposite end, having collars b3 b3, between which t the anti-friction bear- 5o ing-wheels b4 5*, which are journaled upon suitable studs,a c ,secured to the frame or standard A. A strap, c', secured to thefranneserves to hold the spindle in place on its anti-friction wheels.

C is a spindle fitting loosely in the hollow spindle B, having a driving-gear, c, secured on its inner end, and a pulley, C', on its outer end.

C2 is a friction-clamp attached to a bracket,

C3, on the frame, and consisting, preferably, of 6o apair of wooden blocks secured together at one end by an adjusting-screw or threaded bolt,C*.

D is a revolving spool-shaft upon which the spool is supported. This shaft is rotated by means ofa bevel-gear,d,thereon,which meshes 6 5 with a bevel-gear, cl, on the shaft d,journaled y on the spoolframe, and which shaft has a spur-gear, d, that meshes with an intermediate gear, d, which is driven by the gear c on the end of the shaft C.

E is the vibrating guide-arnLhaving ayoke or forked end e e, pivoted to the large hollow spindle B of the frame B. This vibrating arm carries on its free end a pair of skeleton guiderolls, F F, between which the wires pass and are guided to the spool. The arm Eis vibrated back and forth from one end of the spool to the other by means of a heart-cam, G, journaled on the frame B,which operatesapivotedlever,

g, connected by a pivoted link, g', with a pro- 8o iecting arm or lever, g2, on the vibrating arm. The heart-cam wheel G is intermittently rotated from the spool-shaft by means ol" what is known asa Geneva stop or gear-thatis to say, a cam-wheel, H, havingapin, h, on the spool-shaft D, which engages a cani, II', cast integral with the heart-cam G, and which cam H has notches h', thatengage the pin 7L. The rotation of the spool-shaft transmits an intermittent motion to the heart-cani wheel,and the 9o heart-cam transmits a rectilinear motion to the link g', and this link gives a vibratory move- Inent back and forth to the arm E and the guide-rolls F F, mounted thereon.

The spool-shaft revolves whenever the tension on the strand being wound around the spool is not sufficient to overcome the friction of the clamp C2 on the friction-wheel C'. I/Vhen the tension on the strand is the greater', the

wheel C of course turns in the friction-clam p. 10o

ler-frame from the driving-shaft K3,and the pulley K4 is belted directly to thepulley C', the friction-clamp of course being loosened or removed.

In the modification shown in Fig. 5 the bearing for the spindle at the driving end of the twister-frame is of the ordinary form, but connected by a horizontal pivot, a?, to the Standard, A, so that the bearing may adjust itself to the axis of the twister. As no rigid and unyielding frame is employed to support the twister, the frame consisting simply of a pair of standards the feet of which are screwed or otherwise secured to the floor, and unconnected together except by the driving-shaft and twister-frame, the bearings might not always properly align each other if iixed rigidly to the standards. While the anti -friction bearing, as shown in Figsl and 2,is employed, there is no necessity for pivoting it.

While the twister and spooler, as shown in the drawings,is specially designed for twisting and spooling fence-wires, my invention may be used for twisting and spooling other strands or filaments.

The large spindle B or its collar b5 turns on the anti-friction bearing wheels bf5 b, which support the weight of the twister, while the blocks b' b', fitting on the groove b, serve to keep the twister-frame in place.

I claiml. The combination, with twister-frame B, of spool-shaft D, vibrating guide-arm E, having yoke or forked end e e, pivoted to said twisterframe, and provided with a projecting arm,g2, link g', aheart-cam,G,and aGenevagea'r movement for intermittently operating said heartcam from said spool shaft, and means to rotate ythe spool-shaft, substantially as specified.

2. The combination of spool-shaft D, pivoted vibrating arm E, link g', pivoted to said arm, lever g, cam G, cam H, having notches h', and cam H, having pin h, substantiallT as specified.

CHRISTIAN C. HILL.
