SPECIFICATION forming part of Letters Patent No. 496,480, dated May 2, 1893.

Application filed August 3, 1892- Serial 110.442,.395. (No model.)

,To all whom it may concern.-

Be it known that we, HERBERT E. HAM- ILTON, NAPOLEON BOISVERT, and GEORGE OHAMPOUX, of Salmon Falls, county of Strafford, State of New Hampshire, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Our invention relates to improvements in looms, and has for its object to prevent the shuttle acted upon by the picker-stick, from flying off the raceway of the lay as the shuttle is thrown from one to the other shuttlebox.

Numerous devices of more or less complicated construction have been employed to prevent the shuttle from flying out of the loom. This trouble results, we consider, primarily from the imperfect manner in which the shuttle is impelled by the picker stick. We seek to overcome this objectionable feature by so directing the blow of the picker which impels the shuttle, that the shuttle will have a tendency to follow closely against or hug the face of the reed, and we have effected our purpose by inclining the slots or guides near the bottom of the shuttle-box of the lay in which the picker-sticks Work so that the said picker-sticks impelling the shuttle will also be moved forward toward the front of the lay, a picker and picker-stick having such movement serving to deliver a blow against the shuttle which will propel the shuttle across the lay in such manner that its leading end has a tendency to keep close to the reed, and as a result thereof, the shuttle runs practically parallel with the reed and has no tendency to fly off the lay, and the warps are not injured.

Figure 1, in perspective shows a portion of one end of a lay and shuttle-box and Fig.- 2, is a top or plan view, but on a smaller scale, of a lay provided with diagonal slots in accordance with our invention.

Referring to the drawings, A represents a lay-beam; B one of its swords; O, O, pickersticks, all of ordinary construction. The lay has at each end a suitable shuttle-box provided, as shown in Fig. 1,.with a suitable binder a to bear against the shuttle, the binder being acted upon and kept in its operative which the picker-sticks work, the said slots being inclined with relation to the reed, the inner ends of the slots being farther from a vertical plane coinciding with the face of the reed than the outer ends of the slots. Ordinarily these slots are parallel with the reed and with the front sides of the lay-beam. In our invention the inner ends of the slots may be located at the center of the width of the lay-beam, or at one side thereof, as may be found most desirable. As the picker-sticks are moved forward in the slots f by the usual means, the said sticks will be caused to move toward the front part of the lay, such inclined movement of the picker stick causing the picker to bear against the end of the shuttle at an angle to its longitudinal center, and as the picker-stick continues to complete its driving stroke the pressure exerted by it against the shuttle will be such as to give to the shuttle in its passage across the lay a tendency to hug the reed instead of to fly away from the reed. We have found that the movement of the inclined slot to control the picker-stick and thus modify the direction of its blow, results in insuring a straight move ment to the shuttle without tendency to fly off the race, and the warp threads are not chafed or broken.

The extent of inclination of the guides or slots and the details of our improvements may be varied as found desirable, but the principal object is to make the picker bear against the end of the shuttle and move forward at an angle thereto so that it will tend to turn the leading point of the shuttle toward the reed and thus cause the shuttle to run more 5 nearly parallel to the reed.

Having described our invention, what we claim, and desire to secure by Letters Patent, 18*

In alo01n,a1ay having inclined or diagonal 10 slots or guides in the shuttle box end thereof, combined with a picker-stick adapted to be reciprocated in said guides, as and for the purposes set forth.

In testimony whereof We have signed our names to this specification in the presence of r 5 two subscribing witnesses.
