MACHINE FOR MAKING TWISTED-WIRE STRANDS.

SPECIFICATION forming part of Letters Patent No. 579,563, dated March 30, 189'?.

Application filed July 13, 1895. Serial N0. 555,936. (No model.)

To all whom t may concern.-

Berit known that we, JOHN B. CLEAVELAND and CHARLES 'IIERDRICIL citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Machines for Making Twisted-Wire Strands; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in machines for making fence-wire, and 'has for its object the construction of a machine to automatically produce a-twisted-wire fencestrand consisting of four wires, which are first twisted together in pairs and then the said pairs twisted together to form a single strand having the general appearance of a fou r-wire braided strand such as was patented to John B. Cleaveland July l0, 1891i, No. 522,826.

Ve accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which like letters refer to like parts throughout the several views.

Figure l is a view in perspective of our complete machine; Fig. 2, a detail showing the under side of the front end of the bedplate of the machine and attached parts; Fig. 3, a detail in elevation of the wheels for giving the proper tension to the iinished wire before it is reeled, and the figure shows the standards for supporting the Wheels; and Fig. 4 is a detail showing the wire produced by the machine.

A represents the bed-plate of the machine, and a the legs on which the bed-plate rests.

B is a transverse shaft mounted in the journalboxes b on the under side of the bedplate. (See Fig. 2.)

B is a pulley secured to the outer end of the shaft B and is driven by the belt B2.

the bevel gear-wheel C are the two radiallyalined guideways d, within which are secured the radially-adjustable slides D, which form the seats for the vertical shafts D. Mounted upon the upper ends of the vertical shafts D are the wire-carriers D2, which revolve with the vertical shafts, or if it is preferred to make the shafts D stationar.)7 with reference to their supports then the wire-carriers will revolve around the said shafts.

Dsare sprocket-wheels of equal size mounted on the shafts D', whereby the rotation of said wheels will transmit a rotarymovement to the wirescarriers.

E is a sprocket-wheel mounted on the upper end of the shaft c. The shaft o and the Wheel E are both fixed and stationary.

E is asprocket-chain extending around the two sprocket-wheels D3 and around the wheel E, whereby when the bevel gear-wheel C is rotated and the wheels D3 carried around the fixed wheel E the wheels D3 will be `rotated around their individual axes by theaetion of said belt, but in opposite directions to the movement of the wheel C'. The diameters of the wheels D3 are each the same and are just one-halfof the diameterof the stationary wheel E. Thisis an essential feature in the construction of our machine for the reasons as will be hereinafter fully pointed ont. The wirecarriers D2 being secured to the Wheels D3 will also be revolved with said wheels.

Mounted on each of the wirecarriers are the two bobbins F F, carrying the wire.

D'I is a cross-bar supported by the standards d2, which are integral with the carriers, and d3 is an opening through the bar forming a twisting-plate through which `the two wires twisted wires from the wire-carriers D2 are threaded.

By making the diameters of the Wheels D3 IOO just one-half of the diameter of the stationary wheel E the twisting-bars DT will be given twice the speed of the twisting-bar C7 and will revolve in a direction opposite to the bar O7. One-half of the double speed of the bars D7 is made necessary by the rotary movement of the bars around a common center in a direction which counteracts half of the twist that would otherwise be given to the wires as they come from the bars D7. The result is that the twist given to the two wires forming the twopart strands as they come from the bars DT is the same in degree but in opposite direction as the twist given by the bar 0"' to the two two-part strands and enables us to combine the four wires of the finished cable together in such a manner that all four of the wires can be seen at regular intervals in their full thicknessthat is, without overlapping and obstructing the view of each other. By this means we are able to produce a more ornamental and bulkier cable than by any other means.

G is a curved standard which is fastened to the top of the bed-plate and is projected upwardly in the manner as clearly shown in Fig. 1. G is a transverse horizontal shaft mounted on the upper end of the said standard, and G3 is a grooved wheel over which the wire from the eye in the bar C7 passes. The bottom of the groove in the wheel G3 is irregular, the irregularities being made to fit the contour of the twisted fence-strand, so as to secure a hold on the wire and keep it drawn sufficiently taut.

H, H', and H2 are vertical standards secured tothe bed-plate, and H3 is a horizontal shaft mounted on suitable box-bearings secured to the said standards.

I is a shaft mounted parallel with the shaft H3 on box-bearings secured to the standards H and H', but secured so as to be adjustable vertically and being pressed down by the springs g,as shown in Fig. 3. The gear-wheel 71y is mounted on the shaft H3, and the gear-wheel t' is mounted on the shaft I, and the two gearwheels intermesh with each other, whereby when the shaft H3 is rotated the shaft I will be actuated also.

I :is a grooved wheel mounted on the shaft I, and I3 is a disk mounted on the shaft H3 and working into the groove in the wheel I. The periphery of the disk is corrugated and the bottom of the groove in the wheel is irregular, whereby the wire strand from the wheel G2 (which strand is passed between the wheel I and the ldisk I3) is grasped and drawn upon with av tension regulated by the speed of the said wheel and disk.

As the prime object of this invention is to produce a four-strand wire having the greatest possible bull; as distinguished from a compact wire, we find it necessary to carefully regulate the speed of the wheel G3 with relation to the speed of the underlying mechanism for twisting up the wires, in order that the two primary strands will be brought together in the right position at the moment of uniting them. To insure this nicety of action, the depressions in the groove of the wheel G3 are shaped and spaced to take the swells of the wire with much the same regularity that the sprockets of a wheel take the links of a chain belt. The wire as it comes from the twisting-plates is held from slipping, and the speed of the wheel G3, regulated properly to the speed of the twisting machinery, insures the proper tension and takeup of the wire strands to bring them together just right.

M is a sprocket-wheel mounted on the shaft H3, and m is a chain belt connecting the wheel M with the sprocket-wheel G3 on the shaft G', so that the shaft G will be driven from the shaft H3.

M is a sprocket-wheel on the shaftl H3 and is connected by the chain belt M6 with the small sprocket-wheel N on the shaft N'.

N3 is a large sprocket-wheel 'on the outer end of the shaft N and is connected by the chain belt O with the small sprocket-wheel O on the shaft O3, (see Figs. l and 2,) and O3 is a large sprocket-wheel on the shaft O3, which is connected by means of the chain belt b3 with the small sprocket-wheel b3 on the driving-shaft B. Thus it will be seen that the shaft H3 is driven from the shaft B through suitable intermediate gearing whereby the speed will be properly reduced to suit the requirements for the shaft H3.

R is a shaft mounted on suitable bearings secured to the bed-plate. It is provided at one end with a sprocket-wheel R', which is connected by the chain belt R3 with the sprocket-wheel R3 on the shaft H3.

S is a reel upon which the finished wire is wound. Itis mounted 011 the end of the shaft R opposite the end on which the wheel R' is mounted.

T is a feed of any desired or usual constru ction for delivering the wire uniformly to the reel S. Its sprocket-wheel t is driven by the belt R3 in the manner clearly shown in Fig. l.

Having thus described our invention, what we claim as new,and wish to secure by Letters Patent, is-
