2 Claims.

The invention relates to improvements in weaving apparatus and has for its object the provision of a simple apparatus of the character indicated upon which simple weaving operations may be .5; performed and which is of simple construction and capable of economical production.

Other objects will appear hereinafter. The invention consists in the combinations and arrangements of parts hereinafter described and 10 claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification and in which Fig. 1 is a top plan view of weaving apparatus 15 embodying the invention and shown in position v of use;

Fig. 2, a side View of the same;

Fig. 8, a side view corresponding with Fig. '7;

Fig. 9, another view similar to Fig. 1 but showing still another modification; and

Fig. 10, a side View corresponding with Fig. 9.

The embodiment of the invention illustrated in the drawings comprises a rectangular 'weaving frame having a clamping member at one end consisting preferably of two wooden cross bars l adjustably secured together by means of clamping bolts H and wing nuts l2. Projecting from one of the clamping bars ID are two parallel side members 13, preferably formed of metal rods having their ends adjustably secured in sockets M in said clamping bar.

A stretching bar l5, preferably of wood, is secured to the other ends of the side bars I3 by means of sockets l6 corresponding with the sockets I4, as will be readily understood.

In performing the weaving operation a plurality 50 of warp strands H are doubled at l8 around the bar I5, arranged and stretched in substantially parallel relation between the clamping bars I0 with the ends I!) of said strands projecting from the clamp l0 any lengths desired for the length 55 of the woven strip to be formed.

A shuttle needle 20 is provided at one end with an eye 2| and at its other end with a rounded point as shown, the weft strand 22 of the weaving beingthreaded through the eye 2| as indicated in Fig. 3. The shuttle needle is then utilized, as indicated, to pass the weft strand 22 alternately over and under the warp strands ll, the same being doubled around the side bars l3 and then returned through the weft strands in opposite over and under relation until the entire space between the clamp I 0 and the bar [5 has thus been filled with weft strands. When this has been done the clamp is released sufiiciently to permit of the drawing of the strands I! therethrough and the bar I5 is then withdrawn from the ends of the rods I3 and the entire weaving pulled ahead until another suitable length of the stands I! is thus drawn through the clamp H], where-' upon the bar I5 is properly threaded over and under through the strands l1 and replaced on the ends of the rods l3, as indicated in Fig. 4. Then the ends of the strands I! and 22 are drawn or tightened until the weaving is properly consolidated to remove undesirable looseness in the weaving. Thereupon the clamp I0 is again tightened and the weaving continued as indicated at the bottom of Fig. 4 until substantially the full lengths of the strands I l have been utilized in the weaving. The weaving should be stopped at a point where sufiicient unwoven lengths of the ends [9 of the strands I 1 remain to permit of tying of said ends to form a fringe or weaving said ends back into the strip, as indicated in Fig. 6, to prevent ravelling and provide a proper terminal for the weaving.

If desired, asuitable comb or guide member having teeth projecting between the strands I'I may be secured to the clamp Ill to facilitate the movements and proper arrangement of said strands in the weaving frame.

If desired, a heddle or harness in the form of a looped thread may be passed as indicated under one set of the warp strands I! so as to permit of simultaneous raising of said strands to form a shed to facilitate the passage of the shuttle needle 20 in one direction, thus materially facilitating the weaving operation. Obviously the woven strips thus formed may be utilized for various purposes and formed of strands of various materials and colors. The specific form and arrangement of parts constitutes a simple and effective one for the purpose.

In the modification illustrated in Figs. 7 and 8 another clamp i0 is substituted for the stretching bar !5 and the side bars l3 are made flat in,-

stead of cylindrical. In the use of this arrangement the strands I! are not looped or doubled but are stretched singly between the clamps ill, the weaving however being conducted precisely as before.

In the modification illustrated in Figs. 9 and 10, a weaving frame is made up as indicated of two substantially L shaped flat bars 23 and 24 having their shorter limbs 25 and 26 overlapped and se- 10 cured together by clamping bolts 21, thereby forming a clamp for clamping one end of the strands ll. The other end of the frame is formed by transverse stretching bar 28 secured to the bars 23 and 24 by means of clamping bolts 29.

In this arrangement single strands H are held at I claim:

1. A construction of the class described comprising a clamping member having two clamping bars adjustably secured together, one of said bars being provided with a plurality of sockets to receive removably the ends of frame bars; a stretching bar having sockets corresponding with those in said clamping bar and adapted and arranged to receive the other ends of said frame bars; and strands doubled around said holding bar having their ends passing between said clamping bars in substantially parallel relation.

2. A construction of the class described comprising a clamping member having two clamping bars adjustably secured together, one of said bars being provided with a plurality of sockets to receive removably the ends of side frame bars; side frame bars around which the weft thread may be woven; a stretching bar having sockets corresponding with those in the first said clamping bar and adapted and arranged to receive the other ends of said side frame bars; and strands doubled around said holding bar and having their ends passing between said clamping bars in substantially parallel relation.
