LOOM-SHUTTLE.

Specification of Letters Patent.

Patented March a, 1906.

Application filed llecembor 30, 1904. Serial No. 238,953-

To all [Uh-(NIL 2 6 warty concern.

Be it known that I, JOSE}? BIM, a sub'ect of the Emperor of Austria-Hungary, resi ing at Vienna, Austria-Hungary, (having a postoffice address at Kolingasse 19, Vienna, Austria-Hun ary,) have invented certain new and useful Improvements in Loom-Shuttles, of which the following is a specification.

The present improvements relate to means for givin the thread the necessary tension or to hol it taut while it is being used.

The threading and dra r arrangements are securely fixed in the shutt e at the end opposite the clasp hereinbefore referred to for holding the bobbin or cop.

Referring to the accompanying drawings, Figure 1 is a side elevation of the thread arrangement. Fig. 2 is a front elevation thereof. Fig. 3 is a top view. Fig. 4 is a bottom view, the plate e and felt layer 9 having been removed. Fig. 5 is a sectional view on the line A B, Fig. 3, lookin in the direction indicated by arrow A, an Fig. 6 is a sectional view on the same line, but looking in the direction indicated by the arrow B; and Fig. 7 is a rear elevation of Fig. 1 looking in the direction indicated by the arrow C.

The automatic threading and tensioning arrangement devised by me com rises a cylindrical part a, which is shape in such a way that it can readily be inserted in the shuttle. The cylindrical part a has a top, and a diametrical slot 6 passes across the said top, and the thread it from the bobbin or cop is led into this slot. This is done in the usual way, one end of the thread being attached to a fixed pin or catch.

The thread enters and leaves the box a through two openin s in its walls communicating with the slot and spaced preferably about ninety degrees apart, as shown. At one end, as shown in Fig. 2, the slot b co1nmunicates almost directly with an oval opening, and the thread is guided into said 0 ening by a small hook or rejection 0, w ich also prevents the thread from leaving the box. At the opposite end, as shown in F' s. 6 and 7 the slot b directs the thread unlfer the point of a hook, and said hook then diroots the thread around the box to a circular opening through the box, (shown in Fig. 1,) causing the thread to pass around a pin t, extending downwardly into the box. As the shuttle travels to and fro, the thread assumes the position shown in Figs. 3 and 4, assing at an angle around pin i, and it will e seen that the thread enters and leaves at openings which are approximately ninet degrees apart. The box is also rovide with a la er g, of felt or other suita le material, over w ich the thread runs while passing through the box. The layer 9 is of circular sha e and fills the bottom part ofthe cavity of te box a. It surrounds the pin 91 and can be readily reversed or removed and another substituted upon movin to one side the bottom plate e, which is hel in lace by and pivoted upon a screwf. (See Figs. 5 and 6.)

Upon examination of Figs. 3 and 4 it will be seen thatethe thread it traverses two radii of the internal central cylindrical space in the frame a and, as shown in Fig. 6, dra s upon the felt layer g, assing over a relative large length of this fe t, and is thus given a d ue degree of friction.

What I claim is 1. A thread-guide, comprising a hollow box having openings in its walls at substantially right angles to each other, a layer of felt inclosed within the box, and a pin fordirecting the thread through the openings aforesaid and causing it to drag over the layer of felt.

2. A thread-guide, comprising a hollow box having openings in its walls at substantially right angles to each other, a thread-receiving slot across the box and communicating with both openings, and a tension device inclosed within the box.

3. A thread-guide, comprising a hollow box having openings in its walls, a thread-receiving slot across the box and communicating with both 0 enings, a layer of felt inclosed with sai box, and a pin passing through the layer of felt within the ox for directln thread through the openings aforesaid anf causing it to drag over the layer of felt.

4. A thread-guide, comprising a substantially cylindrical box having a diametrical thread-receiving slot in its top and with openings in its walls spaced about ninety degrees apart and communicating with said slot, a central pin and a circular layer of fibrous material concentric with said pin.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
