CIRGULAR-BRAIDING IVIACEIIl'lA Application led .Tune 11, 1917.

Serial No. 174,142.

(GRANTED 'UNDER THE YROVISIONS 0F THE ACT 0F MARCH 3, 1921, Il STAT. Il., 1313.)

To all whom t may concern.:

Be it known that I, GUIDO HORN, a citizen of the German Empire, residing at IVeissensee, near Berlin, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Circular-Braiding Machines (which has been patented in Gen many on an application tiled March 9, 1916, Patent No. 329,100.y and in Great Britain tiled March 1, 1917, Patent No. 164,759 of 1921, and also in Austria filed April 12, 1917, Patent No. 88,101) ,and I 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 tomake and use the same.

Reference is to be had to the accompanying drawings in which:

Fig. 1 illustrates in elevation two thread guiding levers of my improved machine and the curved cam by which they are controlled, Fig. 2 is a diagrammatic view of the paths followed by the threads under the influence of said thread guides. Figs. 3 and et illustrate sample fabrics which may be produced by my improved machine; and Fig. 5 shows a portion of a machine embodying this invention.

My invention shown in British Patent 164,759 of Juney 3rd, 1921, is to be applied to existing braiding machines of the type as shown in my British Patent 26,464 of 1913 in which the guides for the outer threads are so controlled by means of a cam that a fab-ric is formed as illustrated in Fig. 3 and which I shall term a "two-over-two-fabric. In many cases, it is desirable to make by these machines, similarly as by bobbin machines, a fabric in which two adjoining outer threads are so guided into the fabric that both pass over and under the same inner threads, so as to form what may be termed a one-overonefabric, as in Fig. 4 such fabric being a two-and-twdfabric according to its formation.

The` existing circular braiding machines have two-armed or one-armed thread-guiding levers by which all the outer threads are successively guided along the same path. In order to obtain a two-and-two-fabrics, it is indispensable that the threads should alternately move along two distinct paths, unless the unsatisfactory expedient of passing two adjoining threads through the same single cam cooperating with alternately arranged two-armed and one-armed threadguiding levers by which means I am able to device two distinct movements of the thread from only one cam.

Referring now to Figs. 1 and 5, 1 is a two- 65 armed, and 2 a one-armed thread-guiding lever. The nextl lever to the right of Fig. 1 would be a two-armed one, the` next to that a one-armed one, etc. The levers are pivotally carried on standards 3 and t, re- 70 spectively, and provided with rollers 5 and 6, respectively. In lever 1, the roller 5 and the thread eye 7 are on opposite sides of the pivot 8 of that lever, while the roller 6 of lever 2 is between the pivot 9 and the. eye 10.

Both rollers 5 and 6 engage a cam 11 by which the levers 1 and 2 are so guided that the eyes 7 of all the levers 1 follow the dotted line a in Fig. 1, while the eyes 10 of levers 2 follow the full line Referring now to Fig. 2, the desired twoand-two-fabric is hereby formed as follows: The thread of guiding lever 1 follows the dotted curve rt and, in doing so, successively passes over bobbins I and II, under bobbins III and IV, over the two succeeding bobbins, ete, the bobbins moving from the right to the left in Fig. 2. The thread from lever 2 is guided over and under the same 90 bobbins as that from lever 1. It follows the curve b and therefore passes over bobbins I and II', under bobbins III and IV', over the two succeeding bobbins, etc. This causes the two threads or sets of threads to be so placed in juxtaposition as if they had come from a common bobbin. rIhe succeeding threads being thus worked into the fabric in pairs, the desired two-and-two-pattern is produced.

I desire it to be understood that I may, if desired, arrange my one-and-two-armed thread-guiding levers in any relation different from the one described so as to produce dili'erent patterns, without departing from the spirit of my said invention.

I claim:

A1. In a circular braiding machine having two sets of hobb-ins movable in opposite directions, thread guiding levers co-operating with said bobbins, and a common cam for controlling all said levers, half of said levers '5 being one-armed, and hallc ofthern being double-arinech said one-armed and doublearnied levers being alternately arranged.

2. In a circular braiding machine having and the other being double-armed, arranged alternately and of the saine eieotive length, in combination with a. single cain guide engaged by all of the levers so that two consecutive threads are laid along distinct but similar thread tracks for braiding their threads in the saine braid.

GUIDO HORN.
