Application filed November 22, 1928, Serial No. 321,193, and in Belgium April 2, 1928.

The present invention relates to a loom for weaving sheets or strips with leather strings and comprising essentially a frame on which is mounted at one end a sliding table carrying a support to which the ends of all the warp strings are fixed and at the other end a fixed comb to which the ends of one set of warp strings are attached, and a movable cross piece carrying lamella for attachment to the other set of warp strings which can thus be raised and lowered together to permit of the introduction 01 the weft strings.

The sliding table carrying the bar to which both sets of warp strings are attached is preferably capable of sliding motion to regulate the tension of the strings. The vertically movable traverse is mounted on a set of lovers to which a pull spring and operating member are connected.

A form of construction of a loom accord ing to the invention is illustrated by way of example in the accompanying drawings in which Figure 1 is a side elevation of the machine,

Figure 2 is a longitudinal section on the line A E of Figure 3 and Figure 3 is a plan view.

The function of the machine is to produce a flexible sheet of woven leather formed by the regular interlacing of strips or strings of leather.

The uniting of these strings is efiiected by the crossing of two series of strings at right angles to one another. The strings of the longitudinal. are separated from one another and stretched in parallel directions for example in a horizontal. plane. The strings of the second set inter-lace the first set transversely. In the form 01 the machine shown in the drawings, the transverse strings are introduced by hand.

The longitudinal strings are divided into two equal sets, viz, the odd strings and the even strings.

The machine comprises a frame 1 fixed to uprights 2, the length of the frame being suited to the maximum dimensions of the flexible sheets of woven leather which are to be made.

table is mounted to move in a slide 4i formed in the frame 1, wing nuts 5 being provided for fixing this sliding table in place. The tightness of the wing nuts 5 may be regulated in such a manner that the sliding table 3 is dis )laeed automatically by the tension of the strings during the weaving operation.

The sliding table 3 carries an attachment bar 6 to which all the longitudinal strings are attached side by side. The strings may be attached by adhesive or otherwise.

The strings corresponding to the odd numbers are indicated in the drawings at 7 and those corresponding to the even numbers at 8.

The odd strings 7 are attached at their ends remote from the bar 6 to pins 9 fixed to vertical strips '10 which form the teeth of a comb.

The even strings 8 are connected at their rear ends to pins 11 fixed to horizontal strips 12. The horizontal strips 12 are carried by a movable cross piece 13 which moves in the are of a circle.

The pins 9 and 11 are provided with heads to prevent the strings from slipping off. The strings are formed at their ends with holes like button holes through which the heads of the pins are passed.

By depressing the pedal 14, the cross piece 13 is moved through the intermediary of a set of levers 15 and 16 and a cord 17; the lever 16 swings about pivot 19 when the pedal 14 is operated.

The pull spring 18 restores the cross piece 13 to its original position after every depression of the pedal.

The invention has been described and illustrated by wayof example only and not for the purpose of limitation, and it is obvious that modifications may be made in its details without departing from its essential nature. 1

The leather strips maybe mixed with threads or strips of any other substance.

I claim A loom for weaving leather and other strings and strips comprising a frame, a comb fixed to one end of said frame, a cross piece mounted to oscillate in directions parallel to the teeth of said comb and having fingers projecting between the teeth of said comb, means for attaching the ends of one set of Warp strings to the teeth of said comb, means for attaching the ends of a second set of Warp strings to said fingers, longitudinal slidewa-ys in said frame, a sliding table mounted to run in said slideways and having means for attachment to the Warp'strings and means for fixing said last mentioned sliding table in adjusted position.
