4 HAND LOOM Y Filed My 7', 1945 2 sheets-sheet 1 Patented July 29, 1947 UNITED STATES l PATENT yOFFICE HAND LOOM Harry Robertson Dillon, Niagara Falls, N. Y.

yApplication May '7, 1945, Serial No. 592,345 2 claims. (ci. 139-33) This invention relates to an improvement in a weaving machine, and more particularly to weaving looms adaptedto accommodate warp and weft 4loop threads, sometimes termed looper clips.

In the medical field of occupational therapy; which is becoming more extensively practiced, various and sundry devices have been adapted for use in connection with the human hands. For sometime the art of hand weaving has played an extensive part in the aforesaid field; being used for bringing the human muscles into play by the exercise acquired from hand weaving.

One of the most widely utilized hand weaving devices, is a simple frame structure upon the edges of which are disposed pegs adapted to accommodate loop threads, However, this type of loom requires tedious threading of a hook or needle over and under the warp loops in order that a weft thread may be drawn through them.

One of the objects of this invention is the provision of a weaving machine or loom whereby the desired Warp loop threads thereon may be actuated so as to provide a space through which a weft loop thread may be passed, and thereby eliminate the over and under or lacing method now practiced.

Another object of this invention is the provision of a Weaving loom provided with movable pegs for elevating and lowering desired threads on said loom.

A further object of this invention is 'the provision of a weaving loom having certain movable pegs which facilitate the process of weaving, and thereby effect a saving of time in the making of woven articles.

Other objects and features will more fully appear from the following description and accompanying drawings inwhich: Fig. 1 is a top view; Fig. 2 a sectional end View taken along lines 2--2 of Fig. 1; Fig. 3 a side View; Fig. 4 a varied side view; and Fig. a partial sectional end view.

Referring to the drawings the weaving machine or loom I consists of a frame 2 formed by sides 3-4 and ends 5 6. Upon the respective top edges of the sides are disposed a plurality of pegs 'I which are adapted to accommodate loop Weit threads 8. The pegs on side 3 are equally spaced and paired with the pegs on side 4; which are likewise positioned.

End 5 is also provided with a plurality of pegs 9 disposed on the top edge thereof and also equally spaced. These pegs are adapted to provide an anchorage for warp loop threads IUI.

A chamber II is disposed in end 6 and the top thereof is provided with a plurality of apertures I5. An upper carriage I2 is substantially housed in the chamber and is adapted for disposition upon supports I3 which are securedh`to` the walls of said chamber. A plurality of pegs I4 are secured in upright fashion to carriage I2 and are in aligned spaced relation to each other as clearly disclosed in Fig. 2, Pegs I4 respectively register with and extend beyond kthe apertures I5 in the path of said pegs.

A basal carriage I5 is supported by the bottom of chamber II, and its ends thereof project from said chamber, as do the ends of carriage I2. A plurality of pegs i1 are secured in upright fashion upon carriage I6 and are in alignment with and equally spaced upon said carriage. Pegs I1 respectively'register'with and extend through `ori fices I8 in platform I2 and also apertures I5 which are coincident with orifices I8. Apertures I5 and orifices I8 are larger than pegs I4-I'l thus permitting free movement therethrough.

Pegs I4 and I'I likewise are formed in alignment on the edge of end 6 and are directly opposed to pegs 9 on end 5; and the pegs on each of said ends are respectively equally spaced and paired. Warp threads I0 are anchored to pegs 9 on end 5 and pegs I4--I1 in end 6 as clearly disclosed in Fig. 1.

The device functions as follows: when carriage I2 (see Fig. 4) is elevated, pegs I4 rise and the warp threads on each of these pegs also ascend, while the warp threads secured to pegs I1 remain in horizontal position. The threads on pegs I4 are therefore in spaced relation to the threads on pegs I1 and thus form an opening through which one of the weft loop threads 8 may be drawn by a hook 20 and anchored respectively to pegs 'l nearest end 5.

It will therefore be noted (see Fig. 1) that by the foregoing operation the weft thread has been woven over and under the warp threads by simply passing it through the said opening and sliding it under the elevated warp threads to its said anchorage point.

Carriage I2 is then lowered upon supports I3 and carriage I6 is elevated. The warp threads I on pegs l1 (see Fig. 3i are elevated while the threads on pegs I4 remain in horizontal position and it is therefore obvious that another opening is created and at the same time the weft thread already anchored is locked. Another weft thread is passed through the opening and slid under the elevated warp threads I9 on pegs I'I and anchored to the pegs 1 which are second in line from end 5.

By repeating the foregoing operations in alternate fashion the article to be woven is produced.

The edges of the loop threads are then laced, as is well known in the art, and the woven material is completed.

The size of the woven article depends upon the size of the frame and number of pegs and this may be Varied as required.

Warp threads I 0 are elastic and the tension tends to pull pegs |4l1 toward pegs 9 thereby holding the pegs in the position they have been placed, without any support from the operative.

Pegs 5 1 are provided with caps to facilitate lacing the edges; since said caps keep the loop threads from coming off due to upward pull in the lacing operation.

Having described this claimed is:

1. In a device of the character described consisting of a frame provided with two sides and two ends; a plurality of pegs on two of said sides and one of said ends for the reception of a material 20 to -be woven; the other of said ends provided with a chamber, an upper platform and a lower platform housed in said chamber and being independently vertically movable therein, a plurality of pegs on said upper and lower platforms for 25 the reception of material to be woven, said other end being provided with guide apertures for the passage of said plurality of pegs on said platforms, and said upper platformv having aperturesv 3-0 invention, what is 15 4 .for the passage of the pegs of the lower platform, and means for supporting said upper platform.

2. In a device of the character described consisting of a frame provided with two sides and two ends; a plurality of pegs on the two sides and one of the two ends for the reception of a material to be woven; the other of said ends provided with a chamber, independently movable platforms housed in said chamber, a plurality of pegs on each of said platforms for the reception of material to be woven, said other end being provided with guide apertures for the passage of said plurality of pegs on said platforms.
