No. 703,799 and No. 764,479, granted to me tively. A The object of the present invention is to ovide a new and improved hand school oom, arranged to permit the weaver to qlpickly andconveniently 0 en and change t e shed for the passage 0 the shuttle or needle used for carrying the weft through the open shed. r

The invention consists of novel features arts andcombinations of the same, whic will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment .of the invention is represented in the accompanying drawings formimg a part offthis speclfication, in which similar characters of reference indicate corres onding parts'in all the views.

're 1 a plan viewof the improvement; Fig. 2 is aside elevation of the same;

Fig. 3 is an enlarged sectional side elevation of the improvement,.showingthe heddle in one positlon for h'oldiriglthe shed open, and

Fig. 4 is a like'view of e same, showing the heddle in another position for changing the tion.

side bars A, connected with each "other by the aced'slots or notches the strands'of the warp C, also engagedby the slots of the lay D used for beating ulp the weft E, inserted t e warp byaneedle or manipulated by the weaver. The loom so far described is the same as illustrated and described-in my prior patents The strands'of the wa :0 are engaged by ddle G, in the form I .on the sides A, A of. theloom frame, the heddle ,being located 'refembly immediately in the as plainly ind cated in on July 1, -190 2, and July 5, 1904, respec'-.

. venient Figs. 1 and 2. The heddle G is provided-on the top with s aced alternating slots or.-

notches G G or the reception of successive strands of the warp O, the slots Gr starts ing at the forward top corners of the heddle bar and extending in a rearward and downward direction, while the slots G start at .the rear top corners of the heddle bar and extend in a forward direction, the bottoms of the said slots G G3 being approximately in a right-angle position, one relative to the .whenin the position shown in Figs. 1, 2 .and '3, raises alternate strands of the warp (3,. .while the remaining strands of the warp are in a lowermost bottoms of the slots G is turned into the osition shown in Fig. 4,

C osition, that is, in the and when the heddle thefi, the strands of-t e warpG in the slots G are lowered, while the other strands are raised. Thus, in either case the alternate warp strands are raised and the others lowered to form an 0 en shed C for the conpassage of t e needle or shuttle F employe for carrying the weft E through the open shed C" in front of the lay D, to e subsequently beatenup by the weaver moving the lay D forward.

From the foregoing it will be seen that the p weaver by alternately turning the heddle G, The frame of the hand loom consists of the as described and illustrated in Figs. 3 and 4,

t angle one can quickly open the shed for the convenient assage of the needle or shuttle F, to greatly acilitate theweaving operation.

By havin the ends Gof the heddle G re vided W'ltl1 eveled surfacesarranged in armony with the bottoms of the slots G G it is evident that a positive raising and lowering of the corresiponding warp thread takes place whenever e position of the heddle G 1s changed,.as above explained Having thus described m invention, I
