Specification of Letters Patent.

Patented Oct. 24, 1916.

Application filed January 21, 1915. Serial No. 3,567.

To all whom it may concern Be it known that I, ADoLF DANGL, subject of the Emperor of Austria-Hungary, and resident of 25 Lowengasse, Vienna III, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Methods for Covering Rings with Threads, of which the following is a de scription.

The present invention relates to a method for covering rings, especially wire rings destined for linen buttons with a single thread in such a manner that the same may not be drawn open and that the ring body is surrounded in its cross-section by the thread and may also be covered with thread sections running radially or lying in chords to the circumference of the ring.

In the known methods for covering rings with a thread the thread is passed around the ring so as to form a loop and the thread is drawn through said loop so as to lock it. The loop is thereby formed in the known methods at that side of the ring which is turned away from the path of the shuttle so that the loop must be passed around the ring to come within the reach of the shuttle. This movement is effected by transmitting the loop which-has been drawn out by meansof a needle provided with a hook to a holding member which is movable into the path of the needle and of the shuttle, said member carrying the loop around the ring body and back to the path of the shuttle whereafter the thread of the shuttle is passed through the loop. Another method consists in catching the loop by means of a second hook of a needle provided with two hooks and drawing it at the outside of the ring after a lat eral movement of the latter into the path of the shuttle so as to enable locking.

According to the present invention and in contrast with the two known methods above referred to the loop is formed at that side of the ring which is turned to the path of the shuttle so that the shuttle may directly pass through the loop for locking it. In this method the loop is not turned around the ring but is drawn tight at the same place where it has been formed, while the running thread is laid around the ring when the shuttle passes through the loop. In this manner covering of the ring with thread is very simple in comparison with the known methods above referred to.

If it is desired to produce, by meansof the single thread covering the cross-section of the ring, spun rings, that is to say to cover also the opening of the ring with radial or spoke-like thread sections, the method is carried out in such a manner that the ring body is sewn around one or several times at one point with thethread as stated herein before and that the thread is then passed across the opening of the ring for covering the body thereof at the opposite part in the same manner by sewing it one or several times around the body of the ring, whereafter it is returned to the initial point to be there sewn again around at the side of the first windings, which procedure is repeated until the ring is wholly sewn and spun. Since the needle forming the loop is situated at the same side of the ring'as the shuttle so as to be able to draw the loop to said side, it is necessary to draw the thread at the other side of the ring that is to say at the side which is turned away from the path of the shuttle, in order to obtain at this side a thread section bridging the ring opening partly or wholly and extending within the reach of the needle so as to permit formation of the loop, said section being caught by the hook of the needle which passes through the opening of the ring and draws the loop to the side of the shuttle which travels through the loop for looking it. If in the manufacture of spun linen buttons, the ring opening is also to be covered with thread sections the thread is alternatively carried from the one and the opposite side across the opening of the ring and is drawn by the hook of the needle into the path of the shuttle which in its to-and-fro movement forms the thread sections covering the opening ofthe ring which are then locked by the loops running home after the shuttle has been passed therethrough. When forming a button with sections covering the opening of the ring, the ring may also, after having been sewn around at a point one or several times, be turned one or several times around an axis which is situated perpendicularly to the running thread so as to form several thread sections covering the opening, the last of said sections at the side opposite to the hook being used for forming the loop.

In the accompanying drawings Figures 112 are representing the several steps of the method as it is carried out by drawing a thread section so as to bridge the opening of the ring and to enable the formation of ing the opening thereof and being produced plan view of a ring produced by this methodform a loop (Fig, at).

by said method. Fig. 1st is a plan view of a spun ring which is manufactured by the same method and is provided with parallel thread layers covering the opening thereof.

Figs. 1517 inclusive are representing a modified form of execution of the method;

Figs. 18 and 19 show a spun ring produced by this method in plan View and cross-section, respectively; Figs. '2033 represent the above referred to method in which the thread section serving to form the loop is obtained by tilting the ring; Fig. an is the and Fig. 35 shows a modification.

For carrying the method into practice the ring 1 is covered with a thread by sewing or spinning by means of a hooked needle 2 and a shuttle 8, crossing the path of the needle and traveling across the opening of the ring. YVliile in the known methods the path of the shuttle is situated at the side ofthe ring which is remote from the needle, the shuttle according to the present invention is traveling at the side of the ring facing the needle so that the running thread isdrawn across the ring at the side facing the needle? (Fig. 1). If the shuttle has reached one of its two end positions, a guide 5 which is arranged beneath the path of the shuttle and which is oscillating around the ring takes the thread and assisted by the tightener 6 draws the same below the ring 1 so as to form a looped section bridging its opening (Fig. 2). In the following progressive movement of the needle 2 the same passes through the opening'of the ring (Fig. 3), catches the upper part of the thread section passing around the guide 5 and bridging the opening ofthe ring, drawing said section on its return stroke into the path of the shuttle so as to Now the shuttle passes in its movement to the right hand side (Figs. 5 and 6) thro 'h the loop, whereupon the thread isslipped off the guide and h h els oi he edl 50 t a on th f lowing hand stroke of the shuttle the loop tightens under the action of a second ti 'htener 6" and locked to the ring body For the purpose, of covering the open ng of the ring "with thread layers which are arranged radially or parallel to a diameter-the ring is now turned in its p an 9 shif d r eree el h a extent equal to the of two layers or sections and the operation is repeated at the opposite side of'the ring. A second guide 5"'provided at that side of the ring draws hetehrth t ree hel the op ni o t es (Fig-p8), and th up er S i n o s raf s are p t term a e r e i s within the path of the shuttle (Figs. 9 and 10) so that the shuttle in its return movesaid loop (Fig. 11) and the loop after having left the guide and the needle is drawn tight under the action of the tightener 6 (Fig. 12). The ring is then again turned or displaced and the thread is carried around the left hand side of the ring as already described, until the ring is wholly covered with the thread. Owing to the fact that the thread is tightened and bound to the body of the ring alternatively at opposite sides of the ring during the reciprocating movement of the shuttle, the ring is covered in its step wise turning movement with radial thread sections 7 as shown in Fig. 13 or with parallel said layers or sections being fastened to alternating sides of the ring by means of the loops 8. The thread layers covering the opening of the ring are thereby arranged at one face and the loops at the other face thereof (Figs. 13 and 14;).

In order to facilitate entering of the shuttle into the loop the same may be tilted sections '7 as shown in Fig. 1% when it is 1 displaced sidewise instead of being rotated,

by means of the hooked needle by turning the same around its axis to an angle of about is crossed and opened toward the path of the shuttle so as to avoid misses. Besides, turning of the needle has the effect that the hook takes only the branch of the thread position indicated in Fig. 15 so that on passing of the shuttle through theloop (Fig. 16) and on subsequently tightening the loop the same is tied into a knot with the running thread 4; (Fig. 17) In this manner the single sections or layers '7, 7 of the thread covering the opening of the ring are held firmly/in position (Figs. 18 and19),

. and loosening of the windings covering the ring body as it occurs in coverings made according to the known methods, is prevented effectively. 7

"The manufacture of covered rings by sewing and spinning threads around rings of wire or the like may also be effected with the use of knots as mentioned hereinbefore, in the following manner.

If the thread has been fined at one place of the ring body 1, for example at b and the running thread 4 has been stretched above as indicated in Figs. 4-6 so that the loop the opening of the ring, the shuttle 3 being a lrnot at 7) (Fig. 27).

situated at this moment at the left hand' side of the ring 1 remote from b (Fig. 20), fthe" ring is turned in the direction of the arrow through an angle of 180 in such a manner that the thread t passesaround the ringas' indicated in Fig. 21. Thenthe shuttle moves into its other end position so that the thread stretched beneath the ring is free to be" caught by the hook ofthe needle '2 (Fig.

The needle passing through the open ing of; the ring takes the thread (Fig. 23)

and draws it upward to form the loop (Fig. l

which after having been twisted (Fig. 2-5) is traversed by the shuttle 3 returning to the left hand side (Fig; 26) the loop bein g thereby tightened under the coaction of the tightener 6 which moves in a direction opposite to the direction of movement of the shuttle so that the loop is knotted at a place a of the ring body opposite to the preceding The shuttle is now again in its initial. position as in Fig. 20 but the thread 4 crossing the opening of the ring is twisted (Fig. 31') and traversed by the.

shuttle 3 returning to the left hand side (Fig. 32). The loop after being released from the needle is tightened under the coac tion of the tightener 6 (Fig. 33) and is knotted at the place I) of the ring 1- oppo site to the place a where the last loop has been knotted. Then the ring is againgturned and the operations are repeated as described hereinbefore until the ring is wholly wound and covered with thread. In this manner the ring isprovided with a covering formed by a single thread which covering has in distinction from coverings formed-by the known methods no loops which are passed around the ring. lhe ring which is rotated or displaced intermittently or stepwise in its plane and turned about a diameter perpendicular to the path of the shuttle is only spun with radial or parallel threads which are knotted alternatively at opposite sides of the The covering of the ring may, howring. ever, also be executed, if desired, by turning the ring through an angle of twice or more times 180 whereafter the thread is knotted. In this manner the ring is provided with one or more unknotted thread sections 10 (Fig. between the knotted sections 7.
