4 Claims.

This. invention relates to a loom and more particularly to a guard for the shuttle.

In the operation of a ly shuttle loom the shuttle is thrown across the race. of the lay from the shuttle box at one end of the lay to the shuttle box at, the other end of the lay through the shed of the warp. As the loom is speeded up to increase the number of picks, the shuttle will take a more irregular path of movement across the race of the lay. The leading point frequently inclines upwardly as it is thrown from one box to the other. The warp threads will in many instances serve. to prevent the, shuttle from leaving the race or inclning to too great an amount. But in some cases the shuttle may pass through the Warp should a warp thread beneath the guard need' tying in or replacing.

Another object of the invention is to provide a guard which may be slid out of the way to a different position along the lay to afford greater accessibility to the warp threads which it Would cover when in operating position.

Another object of this invention is to position `the guard so that it will engage the shuttle before it reaches the vselvage of the cloth.

With these and otherv objects in view, the in-` vention consists of certain novel features of construction, as will be more fuly described and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a front view of a fragmental portion of the lay showing my guard in position thereon;

Fig. 2 is a sectional View on line 2 2 of Fig. 1;

Fig. 3 is a section through the deilector member;

Fig. i is a perspective view of a fragmental portion of the lay illustrating the deflector member in working position; Y

Fig. 5 is a perspective view showing a fragmental portion of the lay with the deector member moved out of working position for affording access to the warp threads which are beneath the deector member when in operating position.

Fig. 6 is a fragmental front view of a portion of the lay showing a modified arrangement of the guard.

'.In proceeding with. this. invention I have mounted brackets on the cap bar of the, reed in which brackets. spaced cylindrical rods.. are

.mounted to extend parallel Vtothe race of the Veach bracket. The deflector member can never be. moved from. an operating position spaced above the race. of the lay.

With referenceto the drawings,|0 designates the lay which may havesome plate, I I. on its upper surface serving as the race for the shuttle l2 to be guided across the loom. The shuttleis thrown from .a box designated generally |4 at one end oi: thelay by the usual picker stick. to a similar box at the other end of the lay,v which is vnot shown. The reed I5, is mounted in the strip I6 which is set into the lay l0 at its lower edge and is mounted in the .cap bar or hand rail |'I atits upper edge in the usual manner.

On the cap bar l1: I have provided L-shaped .brackets I8 having a. portion I9 slotted as at i3' for the-.reception of-screws 21| to secure them t0 -the cap bar I1.

The outstanding portion 2| of the bracket I8, shown more. clearly in Figs. 2 and 5, is provided with bores 22 and 23 for the recep- .tion of rods 24 and 2.5. which will extend parallel to the. race II. and in spaced relation to. be held in the bores 22 and 23 byset. screws 24pand 25. The deilector member, designated generally 26, and shown in section in Fig. 3, consists of a body .portion 2,1 having bores 2:8 and 29 equipped with .fiber bushings, 3l) and 3| to be slidably mounted upon the .rods 24 and 25.. Theinnei edge ofthe .edge of each deector member 2.6 is curved as at .32.sothat should a shuttle I2, as. shown in Fig. 1,

become raised sufficiently so thatv it comes through the warp threads, it would strike this curved edge `of `the deilector member and be directed downwardly again onto the race I I. This member 'also has a rearwardly extending lip 33 which is inclined, as shown in Fig. 3, to provide a surface 34 which will be generaly parallel to the shed consisting of upper warp threads 35 and lower warp threads 36 which join at the fell 31 of the cloth 38.

A clip consisting of a spring arm 40 having a latch end 4| is secured as at 42 and 43 to the body of the deector member 26. This latch 4| has a beveled surface to engage and spring over the bracket portion 2| and engage the outer surface thereof which forms an abutment so as to hold the member 26 in the position shown in Figs. 1 and 4, which is a location inward from the selvage Warp threads 45 so that should a shuttle go Wild in its travel across the lay it will be engaged before it reached the outer selvage edges.

A bracket 46 is provided with bores for the reception of the rods 24 and 25 and is itself screwed as at 41 to the cap bar I1 as an additional support for` the rods which mount the deflector members.

It is occasionally desirable to vary the size of the shed formed by warp threads 35 and 36. T0 do this the height of warp threads 35 are raised or lowered above race plate I I. To accommodate such adjustment of shed for diierent weaves, brackets I8 and 46 are provided with vertical slots I 9 and 46 through which cap screws 20 and 41 act and which permits vertical adjustment of the whole deilector mechanism. Deflectors 26 should be set to clear warp threads 35 to avoid warp breakage but any excess clearance is disadvantageous in returning a wild shuttle to the shed and the race plate.

In a wide loom such as a 90 sheeting loom it r`might be desirable to mount two sets of these deectors tocover the extra width 'rather than simply to extend the lengths of rods 24 and 25. Otherwise in a wide loom the shuttle might travel too far before it meets a. deflector.

In, Fig. 6 I have shown duplicate mountings extending from the center of the reed cap in either direction to provide two sets one on either side ofthe reed cap center line. In this manner in a wide loom deflectors are provided at suicient intervals so that one will always be engaged should the shuttle go wild.

I claim:

1. In combination with a loom lay having a shuttle race, a hand rail, a reed, a bracket depending from said hand rail, a rod mounted to said bracket to extend parallel to said rail, a mem ber slidably mounted on said rod in front of said reed and having a curved surface facing lengthwise of said race and adapted to be engaged by the shuttle in abnormal flight thereof to deflect it towards said race, and means resiliently mounted in said member for detachably securing said member to said bracket, said member being movable to permit access to the portion of the reed in the rear of said member.

Y2. In a loom lay having a shuttle race, a hand rail, a reed, a bracket depending from said hand rail at one end portion thereof, said bracket havingva shoulder thereon, a rod mounted on said bracket to extend generally parallel to said rail, a. deflecting member slidably mounted on said rod and movable therealong, said member having a portion thereof extending below said rod and in front of said reed, and having a curved portion extending lengthwise thereof with reference to said race and with the said curved portion positioned to be engaged by a shuttle in abnormal flight to deflect said shuttle towards said race,

said member being normally positioned adjacent said bracket and movable along said rod to permit access to the reed portion in the rear of said member, and a latch on said member for engaging said shoulder for detachably holding said member adjacent said bracket.

3. In a loom lay having a shuttle race, a hand rail, a reed, a bracket depending from said hand rail at one end portion thereof, said bracket having an arm thereon depending from said rail and providing a shoulder, a rod mounted on said arm to extend generally parallel to said rail, a deilecting member slidably mounted on said rod and movable therealong, said member having a portion thereof extending below said rod and in front of said reed, said member having a curved portion therein positioned to be engaged by a shuttle in abnormal flight to deflect said shuttle towards said race, said member being normally positioned adjacent said bracket and movable along said rod to permit access to the portion of the reed in the rear of said member, and resiliently mounted means for engaging said shoulder for detachably holding said member adjacent said bracket.

4. In a loom lay having a shuttle race, a hand rail, a reed, a bracket depending from said hand rail at each end portion thereof, a rod mounted on said brackets to extend generally parallel to said hand rail, a pair of deflecting members slidably mounted on said rod and movable therealong, each of said members having a portion thereof extending below said rod and in front of said reed and provided with a curved portion adapted to be engaged by a shuttle moving out of its normal path of travel to deflect said shuttle towards said race, each of said members being normally positioned adjacent a bracket with the curved portions facing each other and movable along said rod to permit access to the reed portions in the rear of said members, each of said members having a latch thereon for detachably holding the member adjacent a bracket.
