HAND WEAVING LOOM 2 Sheets-Sheet 2 Filed April 6, 1959 Fiy- 3 United States Patent Office 3,032,971 Fatented May I, 1962 3,032,071 HAND WEAVLNG LOOM Toshiko Kokonoe, 204 Kamiikegami-cho, Ota-ku, Tokyo-t0, Japan Filed Apr. 6, 1959, Ser. No. 804,170 1 Claim. (Cl. 13933) This invention relates to a hand Weaving loom, and more particularly to a new and improved basic loom frame for hand weaving.

It is an object of this invention to provide a basic loom frame for hand weaving which is of low weight, small size, is conveniently portable, and, at the same time, can be made suitable for weaving hand woven fabrics of a wide variety of materials, of any desired width, and of any desired length by joining any number of similar basic loom frames in the two orthogonal directions in the plane of the original basic loom frame.

The details of this invention together with the abovesaid object, other objects, and advantages of this invention will be more clearly apparent by reference to the following detailed description of practical embodiments of the invention when taken in connection with the accompanying illustrations, in which;

FIG. 1 is a perspective view showing one embodiment of the present invention;

FIG. 2 is a perspective View of another practical embodiment of the anchoring device for the warp.

FIG. 3 pertains to FIG. 1 and is a diagrammatic persspective view indicating a portion thereof in the process of hand weaving.

Referring to FIG. 1 of the drawings, reference symbol A designates a principal basic loom frame constructed in the form of a lattice by fastening a plurality of base boards 1 at certain intervals of space to cross-members 2 and 2a each of which has bolt holes 20 at both of its ends for joining. Reference symbol B designates a supplementary basic frame constructed in the form of a lattice by fastening a plurality of base boards 1a at intervals of space to cross-member 2b and supplementary cross-member 3, each of which has bolt holes 20 at both of its ends for joining. Frames A and B are connected on their reverse surfaces by hinges 4 and are so constructed that they can be folded mutually back-to-back. On the upper surface of each of the cross-members 2, 2a and 2b is fastened, by adhesion, an elastic piece, for example, a rubber strip 9 on which the warp threads may be held by means of holding pins, for example, thumb tacks 10. In addition, a plurality of warp anchoring pins 11 are imbedded securely on one vertical side in the longitudinal direction of each of the cross-members 2, 2a, and 2b of the frames A and B. These anchoring pins 11 may be imbedded, as indicated in FIG. 2 in a base piece 13 having L-shaped key holes 15 so that, by fitting these key holes 15 of the base piece 13 to protruding knob 14 affixed to the cross-member 2, the anchoring pin part can be installed and removed at will. Reference numeral designates an angle shaped connecting piece having left and right holes 5a and 5b in its vertical portion for connecting with the cross member 2a and left and right holes 50 and Ed in its horizontal portion for connection to base board 1a, as indicated in FIG. 1. The connecting piece 5 can be fastened to the cross-member 2a by means of bolt 8 and nut 7, said bolt being passed through the connecting bolt hole 20 of the cross-member 2a and through the hole 5a of the connecting piece 5. In a similar manner, the connecting piece 5 can be fastened, through the other hole 512, to the cross-member 2a of a unit basic frame to be connected adjacently. Further, the connecting piece 5 is fastened to the base boards In by means of screws inserted through holes 50 and 5d and into corresponding holes prepared in the base boards 1a.

Moreover, connecting pieces similar to the connecting piece 5 can be attached to the crossmembers 2 and 2b. However, by the use of simple connecting pieces 16 which have left and right connecting bolt holes 17, the aforesaid cross-members may be connected to adjacent basic frames by means of bolts 8 passing through the said holes 17 and nuts 7. In the aforementioned manner, by means of connecting pieces 5 and 16, adjacent, unit basic frames may be connected additively so that the entire assembly, may be utilized in weaving products of broad width. Moreover, if the total length of the basic frame A together with a supplementary basic frame B is too short for the intended use, connecitng ferrules 12 as indicated in FIG. 1 may be fitted onto the ends of base boards 1a and, by means of the ferrules 12, another unit basic frame of similar kind can be connected in the longitudinal direction. It is to be understood that, for the aforementioned means of connection, any other connection means may be so utilized that the same function is thereby fulfilled.

The basic frame of the foregoing description is used as illustrated in FIG. 3, as one example, in which the warp strips 24 and 25 are passed, respectively, through the upper openings 23a and 23b of the diamond shaped frame operative pieces 23; the ends of the Warp strips may be anchored on the pins 11 or are anchored on the elastic pieces 9 of the cross-members 2, 2a and 21) illustrated in FIG. 3; upper rods 20 and lower rods 21 are passed, respectively, through the upper circular holes 230 and lower circular holes 23d of the operative pieces 23, each pair of said rods 20 and 21 defining a row of alternate operative pieces and a row of operative pieces intermediate the alternate operative pieces, both said rows substantially parallel to said end cross member 2; and the aforesaid parts are held above the basic frame on the rod supports 19 supported in turn by the support bases 18. In the weaving operation, the upper openings 23a of the operative pieces through which the warp strips-24 have been passed and the upper openings 23b of the operative pieces through which the Warp strips 25 have been passed are alternately lifted up, thereby vertically separating the alternate warps 24 and 25 so that the strips 24 are above and then below the strips at each change of strip position 25. A scale 22 is flatly inserted between the separated warp strips and then rotated to a vertical position to hold the strips the width of the ruler apart. The woof is passed through the separated strips by means of a bobbin 26, thereby effecting the weaving by progressive steps after each passage of the woof the scale 22 is rotated and flatly withdrawn to allow the warps to be vertically shifted.

As apparent in the description stated above, by this invention, elastic pieces are affixed adhesively to the upper surfaces of the cross-members of the basic frame. Accordingly, the anchoring thereon of the warp strips by means of pins and the removal of the said strips is extremely easy. Consequently, it is possible to anchor and remove the warp strips readily and freely to and from any desired position. Moreover, because the warp an choring pins are provided on the side surface of the cross-members, the afiixing of the warp strips at fixed positions is also convenient. Therefore, by this invention it is possible to obtain a device which has excellent characteristics as a basic frame for hand weaving, the vital requisite of which is simplicity and convenience. Moreover, because by this invention, the basic frame is made in the form of an integral, single unit of lattice form of light weight and, in addition, is of such a construction that additive extension in either of the orthogonal directions in its plane is convenient, the said basic frame is conveniently portable and remarkably convenient for hand weaving woven fabrics of any length and width.

While several and various changes and modifications can be made in the above described details without departing from the spirit and scope of this invention, it is to be understood that the invention is not to be limited to the details described herein except as set forth in the appended claim.

I claim:
