ANTON GARTENMANN, 0F NEW YORK, N. Y.

IMPRQVEMENT IN LOMS.

Specification forming part of Letters Patent No. EG,241, (lated January R0, 1877; application filed June 15, 1876.

To all whom 'it may concern:

Be it known that I, ANTON GARTENMANN, of the city, county, and State ot' New York, hfve invented a new and useful Improvement in Looms, which improvement is fully set forth in the following specification, reference heilig had to the accompanying drawing, in whoh- A Figure 1 is e front elevation ot' my improvement, the front ofthe loom being removed to show the lay. Fig. 2 is a vm'tieal crosssecA tion in the line w m, Fig. l. Fig. 3 is an enlarged view of a cross-section through the lay, at m w of' Fig. l. Fig'. 4t is an inverted View ot' the weft-carrier. Fig. 5'is a longitudinal section ofthe weft-carrier in the line y y of Fig. L

This invention relates to a method of in sorting the filling` or weft in the shed ot' the y warp without the aid ot a shuttle or shuttleboxes. A weft-carrier is arranged at the free end of a spring-blade, which winds upon a disk attached to the end ot' the lay, and adjacent to the face ofthe lay. Each end ct the lay is provided with a weft-carrier.

The back ofthe disk is provided with a pulley, to which are fastened cords, which are Wound around the pulley in such a manner that by drawing the cords off the pulley the disk will be turned in the direction in which the cords are drawn oft', one cord winding on when the other is winding oi'i'. The weft-carrier blade is fastened at its inner end to the periphery of the disk, which is grooved or made with a anged rim, to prevent the blade from getting oli' the disk as it is being wound or unwound.

When the disk is turned in the proper direction the blade is nnwound, and the carrier, atits free end, is consequently projected along the front of the lay, across the fabric which is being woven, and through the shed, for the purpose ot laying` in the shed a wettthifead, which the carrier has caught in beginning its movement.

The weft-carrier is guided in this movement by a series of double fingers, which are adjnstably attached to the front ot' the lay, and between which tingers it takes its course, the inner sides of the fingers being grooved to receive the edges ot' the weft-carrier and springblztde in their grooves, so that the fingers both guide and support the carrier and blade. The lingers perform these ollces for both the weftcarriers.

The wett-threads are stretched in the same general direction as the warp-threads; but thev are arranged outside ot' the ends othe. reed, between its ends and the disks ol" the weft-carrier,and lower than the top of the disk, so as to be out ot' the way ot the wett-I carrier, except when it is desired that any ot the wel't-threzuls shall be engaged by the carrier, at which time such wett-thread is raised and brought in front ot' the carrier, so as to be caught by it and carried through the shed across the l'abrie to the selva-ge on the other side, where it is detained and held by a needle which is raised up through the mouth ot' the carrier, and behind the wett-thread, the

Aneedle being held up while the wett-carrier retires, so that the wett-thrcml is stripped from the carrier by the needle, and held by it until the clninge ot' the shed locks the weftthread in thc warp.

The movements ot' the carriers and needles are derived from cams on the driving or can] shat't ot" the loom, which will be pointed out as the description proceeds.

The letter A designates the trame of the loom, and B is the lay, on the front ol" which, near its ends, arc arranged disks G C, which areso connected to the lay that they are free to turn on their liournals. rllhe rear sides of the disk are provided with grooved pulleys l) l), in whose grooves are cords E, which are secured to the pulleys and wound around them in opposite directions, so that when the cords are drawn in one or the other direction, the pulleys and the disks on which they are formed will be rotated accordingly, the arrangement heing such that while one cord is winding ott' the pulley and turning the disk, the other cord is winding on the pulley.

The cords E are carried up over pulleys l" F, placed on the upper part nl" the trame ot' the lay, and are conducted thence. downward and fastened to the ree ends ol" levers Gr G, whose other ends are hinged to the hack part of the frame in such positions that they can be operated by cams H lz on the driving or com shut't ot' the loomone set otsaid cams operating` to rotate the disks so as t0 unwind the spring-blades and project the weft-carriers across the loom, and the other to wind them up and withdraw the carriers. The cams are so made and arranged that these movements of the weft-carriers will not interfere with each other, nor with the opening or closing of the sheds ofthe warp.

The weft-carriers I are forked blades formed on the free end of spring-blades J. which are sufficiently elastic to allow them to be wound and unwound upon the disks C, to which one end is secured, and are also suiciently stiff an d stron g to project the carriers forward across the loom. Thespring-blades are guided on the disks by grooves or pins, or other convenient means, and may be incased, if desired, so that they will not be interfered with while wound on the disks, and the friction of the springsin Winding and unwinding on the disks is lessened by anti-friction rollers; but I have not shown such anti-friction rollers in the drawing.

The carriers pass from the disks through a series of double fingers, K, which are arranged so as to allow the carriers to pass between them, the inner sides of the ingers being grooved, as shown most clearly in Fig. 3, to allow the edges of the carriers to ride in the grooves L. The lingers K are adjustably attached te the front ot' the lay, so that they can be set at any desired height thereon, the bodies of the ngers being slotted to receive set-screws, which go through the slots into the lay.

The forward end of the carrier is forked, so as to forni two lingers, M., between which the weft-needle is made to enter. One ofthe tingers is made longer than the other, so as to lead the other in going through the shed, and the longer linger is on the side toward the fell of the cloth, so as to guard the shorter linger and prevent any oll the warp-threzuls from catching in the fork ot' the carrier, the longer finger operating to keep any warpthreads which may be slack from falling 'under or becoming engaged with the shorter finger. The under side of the carrier is provided With hooks a, a, one on each finger, which catch the weft-thread Z1 when the thread is lifted for that purpose by the jacquard or other means.

The weftcarrier is also provided with a guard to prevent its lingers from catching in any Warpthreads which may not be in proper position. This guard consists ot' a two-armed lever, N, pivoted to the under side of the carrier, and so made that its forward end is curved, and its point masks and closes the mouth of the carrier, in which position it is kept by the weighted shorter end of the lever; but when the weft-carrier has been withdrawn back to the disk the weighted end of the lever N strikes against a projection, d, placed on the lay l'or that purpose, and is lifted so as to lower the front end of the lever away from the month ol" the carrier, and leave the carrier open to receive on its hooks ad the weft-thread b, which may have been brought by the jacquard or other apparatus into the required position in front of the carrier 5 but as soon as the carrier has advanced and taken the weft-thread the lever is released, and its front end resumes its normal position and closes the mouth of the carrier. The guard-lever N is seen clearly in Figs. 4 and 5.

0n each side of the reel is a bracket, O, which hangs down from the lay, and carries a slide, P, the lower part of which is perforated to receive the forward end of a lever, Q, which is raised by a cam, R, on the driving cam -shaft at the time when that weft-carrier which starts from the opposite side of the loom has got across the fabric.

The slide P carries at the top a two-armed lever, S, working on a joint, as shown in Figs. l and 2. The upper arm of the lever S is a needle, and the lower arm is Weighted, so that it has a tendency to keep the needle in a vertical position. The needle (there is one at each side where the selvage is formed) is placed in such a position as to be directly under the slot of the weft-carrier when it completes its throw, at which time the cam R raises the lever Q, and forces the needle up into the fork or slot of the carrier, so as to engage the weft-thread, which remains on the needle when the carrier retires. It is necessary that the needle hold the Wcftthread until the reed is very close to the fell of the cloth, and it is desirable to hold ituntil the reed has beaten np the last illingthread, and, therefore, the needle is formed in the manner described, so that its end which holds the weft-thread can stayin the selvage, while the slide which supports the needle is carried forward with the lay when it is beating up, the needle turning on its hinge-joint, so as to prevent injury to it'or to the fabric, and then the cam R allows the le.- ver Q to drop by its own weight and pull down the slide I), and draw the needle S out ofthe cloth.

Fig. 3 represents a shedcomposed of Warpthreads t t, and also one ot' the weft-threads raised to a position where it can be seized by the hooks a c ofthe weft-carrier. l

Fig. 5 shows a weft-thread, b, lying in the hook a ofthe carrier.

What I claim as new, and desire to secure by Letters Patent, is

l. rIdhe weft-carriers with guides K, between jected in laying' in the tially as described.

2. The rotating disks C, operated as described, and the weft-carriers I J mounted thereon, in combination the guides Ii, substantially as set forth.

3. The weighted gnard-leverN, in combination with the weft-carrier I, substantially as described, the same being adapted to close I J, in combination which they are pro- Weft-thread, substanthe mouth ofthe carrier automatically by the fall of its weighted end, and to open the with the lay B and mesme@ same by abutting against the substantially as herein set forth.

4. The combination of' the disk G, spring weft-carrier I J and guard-lever N, subst2mtiaily as described.

5. The hinged needle S, operated through the medium ot' the lever Q and slide P bythe cam R, in combination with the weft-carrier I J, substantially as described.
