' Application filed September 8, 1917. Serial No. 190,399. I

To all whom it may concern I p Be it known that I, (has SWANSON, a citizen of the United States, residing at Ritzville, in the county of Adams and State of lVashington, have invented certainnew and,

useful Improvements in Methods for Inserting Rings in Ropes; and I do hereby declare.

the following to, be a full, clear, "and exact description of the inve'ntion, such as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to the manufacture of halter ties and more particularly to a method for securing the halter ring in the rope during the process :oftwisting the lat tel. a i The present invention especially relates to a method for arranging a halter ring in halter ropes whichare made readily by the use of a. small rope machine which employs a plurality of-rotating hooks spaced in given position about anaxis and to which hooks strand-bights are threaded on a device termed a threader or guide which is provided with a plurality of notches or indents from which the strand-bights pass from the back of the threader toward the twisting machine. My present invention relates to the steps involved in placing a halter ring at the back of a threader plate and in the weaving of the strand-bights through the ring so that when the rope is finally twisted the ring is securely held in one of the finished ropes.

It is an important object of the present invention to provide a method for securing the ring in the halter rope during the twisting of the rope and consists in the steps hereinafter set forth and particularly defined in the accompanying claims. A form ofapparatus with which the invention may be practised is illustrated in the several figures of the drawing, in which Figure 1 is a perspective View showing the strand holder and the twisting machine, illustrating the arrangement of the strandbights between the holder and machine and showing how the ring is passed alongone of the strands;

Fig. 2 is a similar view, showing the ring as arranged behind the threader or guide p ate;

Fig. 3 is a perspective view showing one of the strands being passed through the ring behind the plate;

Fig. A is a perspective view'showing the ring being in its properly fastened position and the strands each respectively connected to appropriate hooks of the wlnding machine.

' Fig. 5 is a detail showing the fastening completed.

While the present invention may be practis'ed 'in various manners as well as various types of apparatus, for the purposes of illustrati'on, the process is practised in the manufacture of halter ropes and there is employed a rope twisting machine M hav--.

ing a series of rotary hooks A, ,B and C over each of which there is passed one or more bights F of a strand of cord which is led toward the machine M from what is termed the threader T or guide which has aseries of notches a, b, and 0, angularly arranged in accordance with the hooksof the machine M.- In threading the apparatus to form rope the supply is held at theback of the plate D and a strand is then run through the threader opening a, through the hoOkA 0n the machine back to a on the threader, across the back of the plate to notch b .and for wardly to hook B back to notch 72 and across the back of this latter to c forwardly to the hook C of the machine and back to the notch c of the threader, then back to b,

on threader, from thence again to hook B back to the notch 12 of the threader and over to the notch c, from thence forwardly to the hook 0 again and back to the notch c and again to a on the threader and from this forwardly to the hook A again and back to the notch a, and the trailing then is led down the back and suitably passed under the caught strands on the back of the threader to secure it. It will be seen that this number of threadings produces two bights on each hook, each bight having two strands, therefore forming a twelve strand rope.

It is desirable to fasten the halter ring R in the end of the halter rope during the manufacture of the latter and for this purpose a set of strands, for instance those leading to the hook B is detached from the hook as shown in Fig. 1 and passed through the ring R and the ends of the bights replaced on the hooks B as shown; the ring then being passed outwardly toward the threader T and around its edge to a position at the back of the threader as clearly shown in Fig. 2 at which time there passes through it four strands of the rope.

The next step as shown in Fig. 3 is to detach another of the sets of strands, as for instance those leading to the hook A and to pass these from the right hand side through the ring R behind the threader plate T which results in the formation of a bight or twist in this strand of the rope when it has been returned to its hook A as shown in Fig. 4. The several strands are equalized by slightly advancing the threader and pulling on the ring B after which the machine is operated so that the several hooks A,' B and C, are rotated during which time the threader T is advanced toward the machine and the twisted rope falls behind the threader in the usual and well known manner.

From this it will be seen that I have provided for weaving the ring R in one end of the rope without the formation of any knots or without requiring the severance of the end of the rope in any manner whatever, and obtain a neat and very secure form offastening between the ring and the rope as shown in Fig. 5.

WVhat is claimed as new is 1. The method of securing a ring in a the bights spring; and then twisting the bights to form the rope.

2, The method of securing a ring in a halter rope which consists in threading the strand-bights, of which the rope is to be formed, detaching-certain of the bights from their twisting hooks and passing the detached bights through the ring to place it between different bights; re-hooking the a. The method of securing a ring in a halr ter rope, which latter is made by a rope machine employing a threader or guide and a series of twisting hooks between which elements the strand is threaded in strandbights; the passage of certain of the strandbights through the ring; the arrangement of the latter behind the threader; the passing of another of said bights through the ring after it is arranged behind the threader; and the twisting of the bights to form the rope.

In testimony whereof I affix my signature.
