5-Claimsi (01. 139- 1663 This invention relates-:to' an improved'picker stick check 'forlooms comprising a pair of parallel rods disposed one on each side of the lay of the loom below the shuttle box and between which the picker stick'may haveoscillatory mo- 5 tion, said rods being adapted-tobe secured to suitable brackets on each side of the lay of the loom and the rods at each endhaving slidably mounted buffer members thereon which areadditionally assisted by'coiled strips of suitable material, such as leather, so as to arrest the picker stick at each end of its throw in'impelling a shuttle out of the shuttle box andin receiving a shuttle into the shuttle box. v Heretofore various types of picker stick checks have been employed, the usual one being an endless leather strap mounted between friction fingers on at least one side of the lay and encircling the picker stick and adapted to be engaged at its ends by the picker stick to arrest. the same It'is an object of this invention to provide an arresting members slidably mounted thereon.

Some of the objects of theninvention having been stated; other objects willappear as-the'description roceeds, when takenin connection with the accompanying drawings, in which Figure 1 is an elevation of'one side of-one end of the lay of the loom and showing a portion of the shuttle box and showing the invention attached to the lay;

Figure 2 is a sectional plan view taken along the line 22 in Figure 1;

Figure 3 is an end view taken along the line 33 in Figure 1;

Figure 4 is a vertical sectional view taken along the line 4-4 in Figure 1;

Figure 5 is a sectional View taken along the line 5-5 in Figure 2 omitting the member 39.

Referring more specifically to the drawings, the numeral l indicates the lay of the loom which has a suitable reinforcing plate II. The loom also has a conventional picker stick l3 driven by a suitable lug strap, not shown, and which has a picker M secured on its upper end for receiving the nose of a shuttle l when it is boxed in the shuttle box.

A suitable box front I8 is shown secured to the top of the lay of the loom by any suitable means such as a plurality of screws H3. The lay has a suitable slot 2| in which the picker stick has movement from one end of the shuttle box to the other.

The two side portions of the lay l0 aregpenetrated by suitable bolts -23 and which penetrate suitable brackets. '25 and 26- which depend xclownwardly and are weldedto rods 21 and 28, respec- ,tively. These bolts 23 and-24, may have threaded nuts 29 On theirinner ends instead of heads, if desired. Theserods 21 and 28, respectively, have reduced end-portions which are threaded as shown in Figure5 for the reception of suitable nuts 3|. I I 1 Adapted to be slid-over theouterends of the rods 21 and28 are suitable members 33 made of any suitable material such as leather. Since suitable openings 36 therein for reception of the rods 21 and 28. Of course, the sheet metal members 34 likewise have coinciding holes to loosely fit over the rods 21 and 28,

" Disposed on each end ofthe rods 21 and 28 are cushioning members ligand E0,'respectively, each having a plurality of holes therethrough and adapted to be doubled upon themselves and 'slid onto the outer ends of the rods 21 and 28,

respectively. ,Whenth'ese are 'in position, a suit- ,able. plate 42 is slid, over the outer endsof the rods 21. and 28 and bears against the shoulders formed by the reduced ends of the rods, and the nuts 3| are then installed to hold the assembled mechanism from being driven off the ends of the rods 21 and 28 by the impacts of the picker stick. The metallic plates 34 are secured to the members 33 by any suitable means such as a plurality of rivets 43.

It is thus seen that when this mechanism is assembled on a loom, the buffer members 33 reinforced by the metallic members 34, and addi tionally retarded by the S- shaped cushioning members 39 and 40 will serve to arrest the travel of the picker stick in both directions during operation of the loom.

It is also quite evident that in the event any of the members 33, 34, 39 and 40 should become worn and need replacement, it is an easy matter to remove the nuts 3| from the ends of the rods 21 and 28 and thus permit a new assembly, or parts thereof, to be quickly installed on the loom.

In the drawings and specification there has been set forth a preferred form of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only,

and not for purposes of limitation, the scope of the invention being defined in the claims.
