TWISTING-FRAME.

Application filed February 18, 1911.

To all whom, it may concern Be it known that we, THOMAS ALEXANDER BOYD and HAROLD ARTHUR BOYD, engineers, both of Shettleston Iron \Vorks, Glasgow, Scotland, subjects of King George of Great Britain and Ireland, declare that we have made an invention which is as follows:

Our improvements refer to twlsting frames in which several single yarns or threads are passed through delivery rollers and are twisted on to a bobbin or spindle and has for its object the more convenient and accurate guiding of such single threads so as to form a well laid cord.

Our invention also includes the means of smoothing the said single threads and of causing rough and irregular parts of the said threads to pass into the center of the twisted cord and so improve the external appearance of the said cord.

Our invention consists of a guide placed in the path of the single threads as they pass from the delivery roller to the twisting spindle. This guide is so made as to keep the several single threads which are to be twisted together separate until the point at which the whole of the twist they are to receive is put into them. The guide referred to is made with radial grooves, one for each thread, and all equally spaced around a hole in the center of the said guide through which hole the twisted threads are drawn. The said grooves are so arranged that the single threads are smoothed on the side of the said threads which is carried to the outside of the twisted cord. By means of these grooves projecting fibers and irregularities on the single threads are turned into the interior of the twisted cord.

Accompanying this specification there is one sheet of drawings.

Figure 1 shows side elevation of spindle flier, top steadier and guide. Fig. 2 shows sectional View of guide and die. Fig. 3 shows plan view of guide and Fig. 4C a side view of delivery roller, threads, guide and wire core.

In carrying out our invention in one arrangement Figs. 1, 2 and 3 we employ six bobbins 1, each filled with the single yarns 2, to be twisted together. We carry the single yarns 2, from these bobbins 1, through a pair of delivery rollers 3, and 4 which are driven in the ordinary manner at the relative speed to the twisting spindle 5, described below which is required to give the necessary Specification of Letters Patent.

twist. Below the said delivery rollers 3, and 4, we mount in the usual manner a twisting' spindle 5, with a flier 6, mounted on same and driven by means of a slot on the spindle top and a key in the flier. At the top of the flier 6 is a boss 7 which passes through a bush 8 and is secured in same by means of a collar 9 screwed on the boss 7 at the top of the bush 8. The bush 8 is socketed in a top steadier 10 which is hinged on a rod 11 in front of and at the top of the spindle 5. In this way when the flier 6 is lifted off the spindle 5, it can be swung upward and toward the front of the spindle 5. its boss remaining all the while in the bush in the top steadier 10. This enables the worker to place the twisting bobbin 12, on the spindle 5, or to remove it when filled. \Ve bore a hole 13 into the boss 7 of the flier 6, from the top side to meet a transverse hole 14 through the boss below the bush 8 in which the flier 6 works. By means of this hole 14. the threads 2 pass from the delivery rollers 3 and 1 to the twisting bobbin 12. On the top of the flier steadier 10 we fix a guide holder 15 with a hole immediately over the flier boss 7. In this guide holder 15, we socket a guide 16 with a hardened steel die 18 central to the spindle. The guide 16 referred to is made in the form of a horizontal disk with a boss 17 which enters into the guide holder 15 and is therefore easily removable for the purpose of threading. On the periphery of the guide 16 we fix at equal distance six curl eyes 19, to receive the six threads 2 which come from the delivery rollers 3 and 4. On the top of the guide we fix a smoothing guide 20 with a trumpet shaped mouth looking upward. In the trumpet shaped mouth 21 we form at equal distance apart six grooves 22 running from a hole 23 in the center radially outward. The six threads 2 are passed from the curl guides 19 described, each one through one of the grooves and downward through the die 18 and the flier 6 to the bobbin 12. As the flier 6 revolves the threads are twisted and are drawn by the twisting bobbin 12 through the steel die 18. As the threads 2 pass through the radial grooves 22 described. the under side of the thread is smoothed and fibers and imperfections on the threads are turned to the top side and eventually are carried into the interior of the twisted thread or cord. It will thus be understood that the worker carries the threads 2 through the delivery rollers 3 and 4, then through the curl guides 19 on the guide holder 16 each thread separate from the others. The worker then lifts the guide and threads the guide and the die placing the six threads each in one of the smoothing grooves 22 referred to. The worker then carries the threads through the flier boss 7 and the flier leg to the twisting bobbin 12. The guide 16 is then placed in the guide holder 15, and the operation of twisting proceeded with. When a bobbin 12 is filled the worker raises the flier 6 05 the spindle 5 and swings it along with the flier steadier 10 and the guide clear of the spindle 5 and the bobbin 12 leaving the threads intact. She then removes the full bobbin, cuts the twisted thread leaving suflicientlength at the flier legs to attach to the new bobbin which is put upon the spindle. The flier with the guide and threads in same is then swung back to working position and twisting proceeds.

In a second arrangement Fig. 4; we employ all the parts referred to in the foregoing first arrangement and in addition we employ a wire 24 which we suspend and fix upon the trumpet shaped smoothing guide 2-0. lVe insert this wire into the interior of the six threads 2 which are being twisted together allowing it to pass say one inch into the guide 20 to form a core upon which the threads are twisted and off the point of which the twisted thread is drawn downward to the twisting bobbin. The object of this core is to form a rounder and more evenly twisted thread or cord.

Having now particularly described and ascertained the nature of our invention and in what manner the same is to be performed we declare that what we claim is 1. In a twisting frame, a delivery roller, a twisting spindle, a pivoted top steadier for the latter and a thread. guide carried by said steadier, said guide having means for receiving separately the threads from the delivery roller and bring them together at the point of efiective twist from the spindle, substantially as described.
