Application filed June 24, 1913.

Be it known that we, JOHN S. BARNES and NATHAN E. Si-innwooo, citizens of the United States, residing at Detroit, county of llayne, State of Michigan, have invented certain new and useful Im rovements in t end-Guides t'or ltopeeM. hing Machines, {J I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. v

My invention relates to rope making; machines and particularly to a strand-guide therefor.

One object of the invention is to provide a strand-guide embodying among other characteristics a frusto-conical body having where and strand receiving grooves and a depend ing handle to which a weight is attached to hold the strand-guide against rotation with means to regulate the tension of the strands in the grooves. I Other objects and advantages will later appear. In the drawings: Figure 1 is a perspective View showing the strand-guide threaded preparatory to twisting the strands around a wire core. Fig. 2 is a perspective view showing several twisted strands disconnected from the hooks they normally engage when being twisted and connected to a central hook to finish the twisting operation.

Referring now to the letters of refer" ence placed upon the driawing'sz-A is a frame which may be secured to a suitable support in any suitable manner.

A denotes a hub in which the shaft-B is journaled and which shaft has a hook B, there being an operating crank C secured to the outer endof the shaft whereby it may be manually actuated.

1) indicates a driving gear mounted on the drive shaft B.

(Z denotes a tr 'nsverse pin set in the shaft and lodged i a recess formed inthe hub of the gear D, thereby securing the gear to the shaft and providing against its lateral movement.

E denotes a with the main driving on stub shafts or bolts arms of the frame.

G are hooks preferably formed of sheet metal, having a bifurcated shank, the tines r of which are secured to. the pinions E in any suitable manner.

H is a strand guide approximately cone shaped, having a plurality of periphe..-al grooves it running longitudinally to receive the binder twine or strand. wires 1, forming the cable and with a central bore it for the passage of a wire or other core around which the strands may wrapped. Y

is :1 depending handle for manually controlling the device, and H is a weight suspended from the end of the handle, -the object of the latter being to prevent the re tation of the strand guide due to the tension of the twisting rope should the handle be. released by the operator.

i are adjustable tension hooksin line with the grooves it, through which the 7 strands l of the cable I J, J, are a pair of swivel hooks, one of which receives the strands of the cable, the

other being connected with a rope or belt K from which is suspended a weight.

K is a pulley or sheave over which the rope or belt K passes.

The device being secured to a suitable support, binder twine or yarn is threaded through one of the grooves in the strand guide H, under its adjustable hook H to one of the several hooks G, thence back through the grooves h in the strand guide to the swivel hook J,-which is located at'a suflicient distance from the twisting device to construct the required length of rope. The twine is looped back and forth from the hook J through the grooves in the strand guide to the several hooks G, to provide the required number of threads desired for each strand. The tension on the several threads of eachstrand being regulated by the adjustable hooks H thedevice is then put in operation by manually rotating the crank arm C, the maindriying we gear D actuating the several pinions thereby twisting the individualthreads of yarn or twine into strands. The rotation of the gears being continued -theseveral strands are twisted together beyond the contracted 1" end of thestrand guide, and as the strands are twisted together the'guide is gradually forced forward by the twisting strands toward the hooks G as will be readily understood. Upon the strand guide reaching a.

point near to the hooks G, the several strands are removed from the hooks G and are looped over the central'h'ook B of the drive shaft. as indicated in Fig. 2. The end of the cable is then grasped by the operator to hold it against rotation and the twisting gear is again operated which serves to twist the strands more tightly together. thereby effecting the completion of the finished rope. If it is desired to construct a cable having a metallic or other core, the wire or other core L. is threaded through. the central bore 71 in the strand guide. as indicated in Fig. 1. the threading of the yarn or twine over the hooks G and the twisting of the threads into strands being effected as previously described. l pon the completion of the twisting of the yarn into, strands, the several strands are twisted around the central core by a further operation of the crank arm as indicated in Fig. 2 of the drawings. l'pon the strand guide being forced up close to the hooks. the strands from the hooks (l and looped over the cen tral hook as indicated in Fig. 1, the cable being completed by grasping the end of the rope. the strands being then twisted close to are disengaged the hook and tightly together in the manner previously described.

Having thus described our invention, what we claim is:-

In a device such as described, a strand guide adapted to be supported by the strands to be twisted and including a frusto-conical body having spaced longitudinal guide grooves therein for receiving the strands to be twisted, and a central longitudinal bore formed therein and "extending therethrough. a depending handle attached to the strand guide. a weight attached to the handle 'for holding the strand guide against rotation. and hooks in the end of the strand-guide at the inner ends of the longitudinal grooves. the hooks being adjustable -in the inner end of the strand guide for engaging the strands in said grooves an regulating the tension thereof.

In testimony whereof. we sign this specificationin the presence of two witnesses. J( )l-l BARXES.
