SPECIFICATION forming part of Letters Patent No. 728,052, dated May 12, 1903.

Application filed January 21, 1902. Serial No. 90,620- (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH WADSWORTH, a

citizen of the United States, residing at Pater-- son, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Swivel-Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to swivel-looms, and particularly to a swivel-shuttle beam adapted to have an intermittent traverse movement and a shifting mechanism therefor to automatically control from the jacquard the movement of theswivel-shuttle beam, and thereby the disposition and location of the figures in the goods being woven.

The object of this invention, as in another described in another. and. separate application this day executed by me, is to provide in a swivel-loom a means for automatically controlling the weavingof figures and the location thereof in woven goods by imparting to the swivel-shuttle beam an intermittent traverse movement in either direction at regular or irregular intervals when required, so that the figures may be placed or woven in the goods at will, making fanciful patterns of almost an endless variety. While the principle is alike in both cases, the mechanism of the means employed. differs. The mechanism in this case I employ in or apply to a plain loom, and the mechanism in -the other case I prefer to apply to a box-loom.

This invention consists in the novel construction, arrangement, and combination of parts hereinafter described, and shown in the accompanying drawings.

In the drawings, Figure 1 is a front view of a portion of my shifting mechanism, the cords which connect the levers to the jacquard being broken off and showing the left-hand lever in its normal position, the right-hand lever being lifted up by the jacquard and its pawl engaging the notched or ratchet wheel for the purposes hereinafter described. Fig. 2 is a side view of Fig. 1, an;d Fig. 3 isa plan view of the same. Fig. 4 is a side View of a portion of a loom, showing the operative connections between the device shown in the previous figures and the swivel-shuttle beam, which is mounted to perform atraverse movement in a support attached to the lay while participating in the reciprocatory motion of the lay. Fig. 5 is a plan view of part of loom with my invention applied thereto, and Fig. 6 is a front view of a portion of a loom to which my invention is applied, the last two figures showing the connection between the swivel-shuttle beam and the supplemental rack'and the means for communicating a traverse movement to both.

7 Similar letters of reference indicate like parts in the various figures of the drawings,

in which G represents a part of a loom-frame; g, the breast-beam; g, the lay-sword; H, the lay, and h brackets secured to the lay.

The swivel-shuttle beam I servesto carry the swivel-shuttles with their'actuating mechanism, which mechanism need not be shown in this application. Said beainhas elongated slots'i, through which studs t", secured to the bar K of the rack lowering and raising device, pass, and the swivel-rack rests andsli'des on said studs. A washer and pink keeps the rack in position on said studs 11. On the bracket h is secured a guide W, in which a slide L is adapted to move, and to said'slide is secured a supplemental rack L, which is connected to the swivel-shuttle beam by the arm Z on the studs Z Z The shaft M passes through a hearing it, secured to the lay H, and on'its upper end is provided with a gear M, made of rawhide, paper, or other suitable material, and which meshes with the teeth of the supplemental rack L. On the bottom of the shaft M or near the end thereof is a gear M the bottom of the said shaft having a female center m. The shaft d has a gear N near the lower end thereof and at the end a male center 1 The said gears M and N mesh, and a bearing 0 for their shafts M and d is formed with an opening in the center 0 and openings 0 in the ends thereof to receive a stud 0 having a male center on top to fit the female center m on bottom of shaft M. A block 0 having a female center to fit the male center (1 on shaft (1, is fitted in the-opening o in the bearing 0 for the adjustmentof the shafts M and d. The shaft d passes through the bearing a of the bracket A, and on the top of said shaft is secured the bevelgear D, which meshes with the bevel-gear D, which is secured to the horizontal shaft (1, mounted in the bearing a of the bracket A. Said bracket A is secured to the end of the loomframe G in any suitable manner.

On the inner end of the shaft 61 is secured an octagon-shaped wheel B, having the eight faces or sides 1). A wheel F, with notches f, is also secured to said shaft d, and between the bevel-gear B and the notched wheel F are fulcrumed the levers E and E, which have fingers or pawls E and E pivotally secured thereto by screws e. Flat springs E and E on studs 6 serve to keep the fingers or pawls in engagement with the wheel F during the operation of their respective levers E and E.

The bracket-supportA has projecting parts a*, and to them spiral springs e are secured, which connect with the outer ends of the levers E and E to hold them down in their normal position, as shown by lever E in Fig. 1. The cords e and e connect the levers E and E with the head motion, which when the pattern calls for it operates the proper lever, lifting it up, as is being done in case of lever E in Fig. 1. There E is partly lifted, the spring E pressing the pawl or finger E down, so that it is engaging the notched wheel F, causing it to turn to the left. The operation is similar when the jacquard, throughthe cord e operates the lever E. The stop-pins a and a keep the pawls or fingers E or E in their normal position, or out of engagement with the wheel F, when the levers are not in operation. (See Fig. 1, in which lever E is down and the pawl E rests on the stop-pin a and is held there by the spring E Stops a and a limit the upward movement of the said levers, and the stops a and a the downward movement thereof. Said stops are secured to the arms a of the bracket A.

On the rear portion of the bracket A are guides a for the square shaft 0, which passes through openings therein and has a cross portion 0 at its lower end, between which and the lower guide a a spring 0 is located and surrounds said shaft O, the expansion of which tends to force the cross portion of said shaft downwardly against the uppermost face I) of the octagon-shaped wheel B, serving to hold said wheel and the shaft cl, to which it is secured, to prevent them from turning except when either of the levers E or E are in operation, when the pawl of the lever which is raised will ride over its stop-pin, engage the notched wheel F, turning it and the shaft 01, to which it is secured, and also causing the octagon-shaped wheel B to turn and in turning to force the square shaft v(3 upward in the guides a, the spring 0 being compressed until the next side I) of the wheel B assumes a horizontal position, when the spring a will expand and press the crosssection 0 down on said face. The bevel-gear D being also secured to the end of said shaft d, it turns therewith, and as it meshes with the bevel-gear D, secured to the upper end of the vertical shaft 61, it turns said shaft, which in turn,through the gears Nand M ,rotates the shaft M, to the upper end of which is secured the rawhide gear M, engaging the rack L, secured to the slide L, thus communicating a traverse motion to the supplemental rack L and to the swivel-shuttle beam.

As is shown in the drawings, when the jacquard operates one of the levers the swivelshuttle beam is moved in one direction, and when it operates the other lever the swivel is moved in the'opposite direction, without in any way interfering with the reciprocatory motion of the swivel-shuttle beam and the lay upon which it is mounted.

The loom represented in the drawings is a plain loom, and 71 in Fig. 4 represents the shuttle-holder..

It will be understood that the jacquard will automatically control and regulate the traverse motion of the swivel-shuttle beam and the disposition or location of the spots or figures to be woven on the fabric.

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

The combination of the lay, having a bracket secured thereon, a member adapted to slide longitudinally in said bracket above the lay and having a rack secured thereto, a longitudinally-movable swivel-shuttle beam, connected with said sliding member, a shaft passing through a guide-bracket secured to the lay, and adapted to rock therewith and provided upon its upper end with a gear meshing with the rack secured to the said sliding member, and having upon its lower extremity a female center, a vertical shaft having a male center at its lower extremity and a gear adapted to mesh with the lastmentioned gear, and having at its upper extremity a miter-gear, a horizontal shaft mounted in bearing-secured to the loom-frame and provided with a miter-gear to mesh with lastmentioned miter-gear, a ratchetwheel secured to said horizontal shaft, oppositely-l0- cated levers pivoted on said shaft, pawls on said levers to engage and turn said ratchet in the direction required, means for limiting the upward and downward movement of said levers, means for withdrawing the pawls from engagement with said ratchet upon the downward movement of the respective levers, said levers being operated from the jacquard, and means for adjusting said vertical and rocking shafts, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
