To aff-Zt whom t may concern,.-

Be itknown that I, HENRY RIEHL, Jr., a citi zen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented new and useful Improvements in Shuttle-Carrying Blocks or Races for Narrow-Ware Looms, of which the following is a speciiication.

My invention relates to improvements in shuttle-carrying blocks or races for narrowware looms; and it consists of means for adjusting the blocks which form the'race, so that the wear either of a shuttle or the blocks which form the race therefor may be com pensated for bythe adjustment of said blocks.

My invention further consists of means whereby a shuttle may be removed from the race without removing a block from the bat ten or beam.

It further consists of novel details of construction, all as will'be hereinafter'set forth.

Figure 1 represents a vertical section of a loom-batten and its adjuncts, the section bemy invention. Fig. 6 represents a form of plate that may be employed.

Similar numerals of reference indicate corresponding parts of the figures.

Referring to the drawings, 1 and 2 designate blocks, which form the race for the shuttle 3, it being noted that the block 1 has secured thereto in anysuitable manner-for eX`- ample, by screws SO-the plates 4, which latter are each provided'with a slot 5 and a projecting member or shoulder 6 and that the under side 7 of said member 6 rests upon a cam member, and in the drawings I have shown a screw 8, held in the blocks 2, which is provided with a conical head 9 for a purpose hereinafter described. The block 2 is secured to the beam 10 by screws ll'orin anysuitable manner, which pass through tubes l2, which latter form journals for the gear-Wheels 13, Which actuate the shuttles 3 in the usual manner. It will be seen that said beam 10 has f and block 2.

suitably secured thereto bysuitable means the posts 14 and that the brace 15 is attached to said posts for evident purposes, it being understood that hereinafter in referring-to the beam I desire it to be understood that I refer to the'beam proper, together with the posts and brace. Y

The operation is as follows: When the space between the blocks 1 and 2 becomes too small fora shuttle 3,due to the swelling of the wood from dampness orI other causes, it is apparent that the shuttle will become wedged between said blocks and will either cease to slide between the same or else will do so under considerable friction, thereby causing a great deal of wear on .the shuttles .and also in the blocks 1 and 2, in which the sameare guided. To adjust the Yspace between4 the blocks 1 and 2, so as to permit the shuttles 3 to move freely therebetween, all that need be done is to loosen the screws 11, as indicated in dotted lines in Fig. 1, whereupon the block 2 may be moved in the present instance to the right, as indicated in dotted lines in Fig. 1, whereupon the plates 4 will no longer be iirmly retained between the beam 10 and the block 2 and may be easily raised or lowered, according to requirements, it being apparent that said plates 4 will cause the block 1, secured thereto to move in unison therewith and that when said block 1 is adjusted relatively to the block 2 said block 1 is retained firmly in position by tightening the-A screw 11, so as to clamp the plate -I between the beam 10 When the adjustment of the block 1 requires only a little movement, this may be accomplished by turning the screws 8, whereupon the plates 4 will` be elevated by lreason of the cone-shaped'heads 9, as will be seen in Figs. 3 and L1. 1f the space bet-Ween the blocks 1 and 2 is' too great, the same may be reduced by turning the screws 8 so that the under side 7 of the projecting members G may rest on a portion of the conical head of the screw S somewhere between the shank of said screw and the outer extremity of its head 9. Vhen it is desiredto remove a shuttle from the race, the screw 11 is loosened, whereupon the block 1 may be raised by hand to the position indicated in dotted lines in the upper portion of Fig. 1, it being noted that the space between the blocks 1 and 2 is then IOO sufficient to permit a shuttle to be removed from the race.

It will be apparent that various changes may be made by those skilled in the art which will come within the scope of my invention, and I do not therefore desire to be limited in A every instance to the exact construction herein shown and described.

It will be apparent that the shoulder or projecting member (3 may project from the opposite side of the plate 4 in a direction opposite to that shown in Fig. 5, or, if desired, two projecting members (5 maybe employed, as shown in Fig. (5.

It will be apparent that the plate or plates 4 maybe attached to the upper and lower blocks l and 2 in a dilferent manner from that shown and that the adjustment of the block may be elected by different means without (lepartiugt'rom the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combinalion with a beam, an upper shuttle-carrying block, a lower shuttle-carrying block mounted on said beam anda plate common to said shuttleblocks and situated between said blocks and the beam, a projection on said plate and au adjusting member upon one of said blocks adapted to engage said projection.

2. In combination with a beam, an upper shuttle-carrying block, a lower shuttlecarry ing block mounted on said beam and a slotted plate situated between said blocks and beam and provided with a projection, means passing through said lower block and plate for supporting the latter and an adjusting member upon said lower block adapted to engage with said projection.

The combination of a beam, an upper shuttle-carrying block, a lower shuttle-carry ing block mounted on said beam, a plate provided with a projection thereon, situated between said blocks and beam, and an adjusting member upon said lower block having a Haring head engaging said projection. l

4. The combination with a beam, of an 11pper shuttle-carrying block, a plate secured to said upper block and having a slot in its lower portion, a projection on said plate, the latter being situated between said blocks and beam, means for securing the lower shuttle-carrying block to said beam, and an adjusting member upon said lower block, said adjusting member having a flaring head engaging said projection, whereby said upper and lower blocks can be moved toward and away from each other according to requirements.

5. In combination with a beam, an independent upper shuttle-carrying block, an iudependent lower shuttle-carrying block, both of which are suitably supported on said beam, and a plato com mon to said shuttle-blocks and secured to one of said blocks, and an adjusting member upon the other of said blocks adapted to engage with said plate for operating the same to adjust the said blocks.
