' beater mechanis'm thereof.

An object in view is the production of an effective 'beater susceptible of and adapted for providing a track or runway for the shuttle while in the lowered or non-stroke position. i

VVith this and further objects in view as will in parthereinafter become apparent and in part bestated, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claimed.

In the accompanying drawings,-

Figure l is a transverse, Vertical sectio through a loom embodyingpthe features of the present invention, the section being taken on appro'ximately the plane indicated by line 1-1 of Figure 2.

Figu're `2 is a horizontal section there-V through taken approximately on the plane indicated by line 2-2 of Figure 1, and looking downward, intermediate portions being broken out for indicating greater width than actually shown.

Figure 3 is a Vertical., fragment-ary section taken approximately on the plane'in-V dicatedby line 3-3 of Figure 1. w

Referring to the drawings by numerals, 1 indicates the frame of a hand loom, which, but forthe beater inechanisin, and its co- Operating parts, may be of any ordinary type. Frame 1 includes side bars 2 between which a beater lever ofbail-like form is swung. This beater lever consists of arms 3, 3, pivoted at 4, 4, to the frame 1, the

` arms being rigidly connected at their ends opposite the'pivots by a cross bar or hand bar 5. The lever thus formed lies below the apex of the Warp shed and above the heddles which are of ordinary construction and are not llustrated. v

A reed frame 6, provided with the reeds 7, 7, between which the warp 8 is laced as usual, is mounted on and fixed to or formed integral withend plates 9, 9, each pivoted at its rear end portion, as at 10, to the ad jacent arm 3. Each plate 9 is arranged above and 111 line with the respective side bar 2. i

In operation, the reed-carrying frame or lever being in the position indicated in Figure 1, the Shuttle is thrust across they-100mv through the shed while resting on the upper edges of the reeds 7 which serve as a track. It is to be noted that when the track isiin i this position, it is perfectly horizontal. As

soon'as the shut-tle has completed its stroke, the reed frame is rapped upward byswinging the lever on the pivot t., the bar 5 being employed as a hand bar for manually laccomplishing this operation. In the starting of this action, the arms 8 begin to rise on their pivots 4 while the end plates V9 begin to swing on their pivots 10 `until the reed frame assurnes a position parallel with the upper edges of 'the lever arms 3 in which position the reed frame will rest directly on said arms and have the end plates 9` overhanging the arms at either side. The further upward movement of the lever brings the reeds 7 into'the beating position against the weft which has just been laid. As the shed is slightly inclined, the opposite in-` clination of the'lever arms 3, when said arms are. raised, will effect a Vposition of the reeds 7 such that they will lie substantially at right angles to the Warp at the juncture of the shed with the Woven fabric, thus afford ing the maximum beating efiiciency. After the beating stroke has been completed, the lever is lowered, and as it descends,the front or free ends of the plates 9 first engage the side bars 2 edgewise, and, thereupon said front ends cease to' descend and begin a swinging movement on their pivots 10 -until the plates 9 rest for practically their full length edgewise on the side bars `2. The reed-carryinglever will be thus limited in its descent and supported in its lowermost `position by the plates 9, and said plates at the same time will sustain the reed frame perfectly flat or horizontal,`so that it is again ready to receive the Shuttle as a-'track therefor.V

The invention herein claimed is illustrated but not claimed in my co-pending application Serial 7 56,219, filed December 16, 19211.

What is claimed is 2- i 1. In loom mechanism, the combination ioo i With a loonl frame, of a level' pivoted thereto, a reed n'lovable relative to the lever located to be advanced by the levelto a iveftbeating position substantially at right angles to the Warp, 'and means forl sustaining'the reed in advance of the return location of the lever.

2. In looln n'leclla-nisnl, the con'ibination,

with a frame, of a level' pivoted thereto, a

reed disposed in the path of the level' for being' advanced by the level' to a iveft-beating position, means for sustaining the reed in advance of the return location of the lever, and means for preventing disloeation of the reed relative to the level' long'itudinally or transversely of the lever.

3. In loom mechanism, the combination, With a loom frame, of a beater lever pivoted thereto, and a reed'franle pivotally connected to said level' substantially 'at that portion of the reed frame nearest the pivotal mounting of the level' for enabling' the reed fran'ie to swing from a beating position to a tracl'- forming position for a Shuttle.

4. In 100m mechanism, tlle combination, With a frame, of a lever pivoted thereto, and a reed pivoted to the lever in position to move With the lever to the weft-beating position'and located to be interruptedhy a portion of the frame during the return movement of the lever to leave the reed in position to sel've as a track for a shuttle.

5. In loom mechanisrn, the combination., with a frame, of a beater level' pivoted thereto, a reed having a frame extending acrosssaid level' and lappingg' the outer faces of the lever, the upper -portions of the level' being adapted to strike the under face ofthc. reed frame for ele'vating` the same to the Weft-beating position, means for preventinY movement of the reed frame long'itudinally of the lever, the reed frame being; free to cease its return movement inadvance ofthe .final return location of the lever, and means for c'ausinp` such oessation of the return movementof the reed frame.

6. In loom mechanisln, `the combination, with a frame, of a beater lever pivoted thel'eto, a reed having a frame extending across said level' in position to be struck by the upper portions of thelever for beingl elevated therewith to the Weft-beating position, means for interrupting the return n'iovement of the reed frame short of the return position of the lever, and a pivotal connection between Vthe reed frame and the lever.

V7. In loom mechanism, the combination, with a frame, of a beater lever pivoted thereto, a reed having a frame exteuding across said level' in position to be struck by the upper portions of the level' for being elevated thereivith to the weft-beating position, means for intel'rupting the return movenlent of the reed frame short of theretul'n position of the lever, and a pivotal connection between the end portions of the reed frame and the lever.

8. In looin mechanisin, the combination, with a frame, of a beater level1 pivoted thereto, a reed'having' a frame extending 'across said level' in position to be struck by to the frame, a hand bar eonnecting the arms, 'a reedV frame extending` across' and above the arms, plates dependlng' from the reed frame in position to lap the'sides of the arms, a pivotal connection between said:

platesand said arms, and means for sustaining the reed frame in a horizontal position When said arms are in their lovvermost .incli ned position; i

10.' In loom mechanisn'i, the combination, lvith a frame, of spaced level' arms pivoted to the frame, a hand bal' connecting the arms, areed frame extending across and above the arms, plates depending` from the reed frame in position to lap the sides of the arms, a pivotal connection between the real' ends of said plates and said arms, and means for sustaining the reed frame in a llorizontal position When said arms are in their lowerlnost inclined position.
