NARROW-FABRIC LOOM.

SPECIFICATION forming part of Letters Patent No. 618,214, dated January 24, 1899.

Application filed January 27,1896. Serial No. 577,011. (No model.)

./'0 all whom it may concern..-

Be it known that I, OSCAR A. STEERE, of the city of Pawtueket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Narrow-Fabric Looms; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improvementiu narrow-fabric looms adapted to weave two sets of narrow fabric one above the other.

The invention consists in the peculiar and novel construction and arrangement of the shuttle-operatin g m echanism whereby the filling-threads are laid in the two superimposed fabrics simultaneously, as will be more fully set forth hereinafter.

Figure 1 is a front view of part of a positive-motion narrow-fabric loom. The breastbeam and other parts not required to illustrate the operation of the shuttles are left out, so as to more clearly show the essential parts. Fig. 2 is a vertical sectional view of parts of the loom, showing the warp, the bed (lles, the lay, the two races, one above the other, and the two banks of shuttles arranged for the weaving of two distinct fabrics. Fig. 3 is a sectional view of the lay, showing the mechanism for operating the two banks of shuttles. Fig. at is a transverse sectional view of the lay, showing the two sh Little-races one above the other, the shuttles, and the mechanism for imparting motion to the two shuttles. Fig. 5 is a perspective view of part of the double rack-bar.

Similar numerals of reference indicate corresponding parts in all the figures.

In the drawings, 6 6 indicate the end frames of the loom; 7, the fabric-take-up roll, which may be operated in any us ial manner to maintain the stretch and take up the cloth or fabric. It is operated in the loom shown in the drawings through thegears 8 8, secured to the shaft of the take-up roll 7, thepinions 0 9, the gears 10 10, the pinions 11 11, the ratchet-gears 12 12, and thepawls 13 13, supported on arms connected with the lay 14:. The rack-bar 15 is supported in suitable ways on thelay 1%. Reciprocatin g motion is imparted o the rack-bar 15 by thestraps 16 16 through the compound gears 17 17, which receive motion from themain shaft 18 through the train-gears 19 19 or in any other suitable manner. The lay is operated in the usual manner from the crank-shaft. It is provided with the-two banks ofshuttles 21 and 22, one above the other, supported in the two races 23 and 24:, and the lay is also provided with thereeds 25 and 26.

Theharnesses 27 27 used are provided withheddles 28, each of which is provided with the two warp-eyes 2B and 28 Thewarpthreads 29, which form the warp for the upper distinct fabric, pass through the upper warp-eyes 28, while the warp-threads 30, which form the warp for the lower fabric, pass through the lower warp-eyes 28 so that each heddle controls one warp-thread of each of the two independent fabrics, and two independent sheds are formed in front of the reed, and the weft laid in these sheds by the two shuttles is beaten up by the reed at one movement of the lay, all of which is clearly shown in Fig. 2. Twelve harnesses are shown in Fig. 2; but the numberof harnesses required depends solely on the nature of the fabric to be produced. Two harnesses, the heddles of which are provided with the two warp-eyes 28 and 28 will be sufficient to form the sheds for the two independent fabrics of single ply.

Referring now more particularly to Figs. 3, 4, and 5, it will be seen that the rack-bar is provided with the tworacks 15 and 15 and that the shuttles are provided at their lower faces with a rack, and that theintermediate gears 31, journaled on shafts secured to the lay, engage with therack 15 of the rack-bar 15 and with the rack on theshuttles 21, while theshuttles 22 are operated by thelarger gears 32 engaging with therack 15 and with the intermediate gears 33, which engage with the rack on theshuttles 22, so that the upper shuttles always move with and in the direction of the rack-bar 15, while thelower shuttles 21 move in the opposite direction, and that by the reciprocation of the rack-bar the reciprocation of the shuttles is secured.

The fabrics pass over the cloth-beams 35 and 36 and down around the take-up roll 7 to the cloth-roll 37, the warp being supplied at the opposite end of the loom in the usual manner.

The lease-rods 38 38 for the upper set of warp and 39 39 for the lower set of warp are supported on twobrackets 40, so that each set of warp-threads for each separate and distinct fabric is supported separately at one end of the loom, and two separate and distinct fabrics are each separately supported on a cloth-beam.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a positive-motion loom adapted to weave simultaneously two independent fabrics one above the other, the combination with the lay, the two shuttle-races one above the other, and shuttles having toothed racks, of the carried by the lay, pulleys on each end of the I,

lay, straps secured to the actuating mechanism and to the two ends of the double rackbar, thegears 31 31 for operating the lower shuttle, and thegears 32 and 33 33 for transmitting the motion of the rack-bar to the upper shuttle; whereby the shuttles are moved to lay the weft-threads simultaneously into the two sheds of two separate fabrics, as described.

In witness whereof I have hereunto set my hand.

OSCAR A. STEERE. \Vitnesses:
