Application filed September 11, 1902. Serial No. 122,907. (No model.)

, To all whom it mag concern:

5, chusetts, have invented certain new and useful Improvements in Weft-Fork Mechanism;

and I do hereby declare the following to be a full, clear, and exact description of the invention', such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the weft-fork mechanism of a loom; and it consists in the novel construction and combination of the .parts hereinafter fully described and claimed. In the drawings, Figure l is a side view of the weft-fork mechanism. Fig. 2 is a plan view of the weft-fork. Fig. 3 isa front view of the weft-hammer.

A is the breast-beam, which isshown in B is the weft-fork slide,and Z) parts are of any approved construction.

0 is the novel weft-fork, which is pivoted by a pin 0 to the slide B. The weft-fork has two prongs d, formed of the end portions of a loop of wire, which is bent double to form a pro- 1 jecting cross-bar e at one end and a shank f.

, D is a pivot-block provided with a central cured to the breast-beam A. The hammer prong g, arranged between the two prongs d.'

has a notch c' in its upper end, which is bev eled, and it has also two small rounded projections on one side. The shank f drops into the notch of the hammer, and the crossbar engages with its projections on each side of the notch, so that all rebounding is prevented.

jections on its side, of a pivoted weft-fork provided with a shank which drops into the said slot and which has also a cross-bar which engages with the said projections, substantially as set forth.

3. The combination, with a pivoted weftfork hammer having a slot in its top; of a pivoted weft-fork comprising two prongs,a shank and an end cross-bar formed of a loop of wire bent double, and a pivot-block slid on the said prongs and provided with an intermediate prong, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
