SPECIFICATION forming part of Letters Patent No. 512,475, dated January 9, 1894.

Application filed- February 25, 1893. Serial No. 463,756. (No model.)

T0 all whom it may concern.-

Be it known that I, JOHN T. KENNEDY, a citizen of the United States, residing at Paterson, county of Passaic, and State of New Jersey, have invented certain new anduseful Improvements in Swivel-Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a new and useful improvement in swivel looms and it consists of the arrangement and combination of parts, whereby the operation of both plain and swivel weaving is accomplished in the same loom, the i'ly shuttle being restricted in its movement at required intervals and the swivel shuttles introduced to weave the required figure in the fabric. I

It consists also in the arrangementand combination of parts hereinafter specified and claimed.

In the drawings Figure l is an end elevation of a swivel loom having attached to the usual well known parts my present invention. Fig. 2 is a vertical section taken on the line x-x of Fig; l, only those parts of the loom being shown asare necessary to illustrate the invention. Fig. 3 is a rear view on a smaller scale of the loom (certain portions being re moved). Fig. 4 is a cross section of part of the loom taken on the line fy-y of Fig. 1. Fig. 5 is an enlarged detail View of the mechanism for bringing the swivel shuttles into operation. Fig. 6 is an enlarged detail perspective view of 'certain levers connecting the picker shoes to the rocking shaft, and Fig. 7 is an enlarged cross sectional view taken through the swivel shuttle beam.

In said' drawings A represents the frame work of an ordinary swivel loom, having the usual driving shaft a, operating through crank b and pitman c the lay d (supported on the lay swords e) in the usual manner.

The cam shaft f, warp and cloth beams g, h and 'L' are all of the usual description.

Power is conveyed to the loom in the usual way.

The picker sticks 7c are actuated by the picker stick leversm in the usual well known manner there being a flexible connection Z between the end of the lever and of the picker stick. The picker stick levers mv are pivoted near one end, as at n, to the loom frame so that they may be elevated or y1depressed by the picker balls or tappets q to actuateA the picker sticks. Each of the picker stick levers m is provided with a cam piece or shoe o which is beveled upward toward the center as at p and said shoes o are each formed on the front end of a bar which is pivotally secured as at o to the top of the respective picker stick lever. The rear ends p of the bars, carrying the shoes o, are connected by two rods r and r2 with the opposite ends of a toggle lever r pivoted-in a bracket r3 on the frame of the loom.

On the cam shaftfis splined a cam t fixed to a sliding sleeve s in such a manner that the sleeve and cam rotate with the shaft f and can slide longitudinally of the same. The sleeve .5f is provided with a circumferential groove into which the prongs of a fork u pass. The fork u is pivoted as at u to the bracket on the loom frame and is operated through a cord us secured to its free end u2, which cord as is operated by the angle lever a4 pivoted in the loom frame. The angle lever is operated by cord a5, angle lever a6, cord ul, pawl u8 and pattern wheel uf. A springe secured to the rear end u2 of the fork and to the loom frame serves to return the fork u, to its normal position when the cord @t3 is released.

The rocking shaft 102 at the rear part ofthe loom is provided with an upwardly projecting armw on the upper end of which the cam can act. Extending downward from the upper end of said arm and slotted thereto to form a means of adjustment therewith is an arm 'w3 connected at its other end by pin co4 to the toggle lever r in such a manner that when the arm wis elevated or depressed, the arm w3 is actuated and serves to turn the toggle lever r in its bracket and thus, through the rods r and r2, swings the shoes o on their pivots o.

At either end of the cam-shaftf are secured the picker tappets q which serve to elevate and depress the picker-stick levers m by striking against the shoes o.

The swivel shuttle beam B is connected by spring controlled rods w guided on the lay to treadles w" secured to the rocking shaft wz, so that when the treadles 105 are depressed the swivel shuttle beam is depressed against the action of th'e springs w7 of the rods wG. The swivel shuttle actuating rack that op` crates the swivel shuttles 61 in the swivel shuttle beam B in the usual` manner is connected through its driver 20 land a link 62 with the crank arm 19 of a rocking shaft 18. This rocking shaft 18 is disposed vertically in suitable bearings on one side of the fralne of the loom.

Directly beneath the cam shaft f is placed, in suitable bearings in a bracket of the loom frame, a shaft 2 on which is splined a sleeve 3, carrying a pinion 1. The sleeve and pinion turn with the shaft 2, but can be moved longitudinally thereon. The sleeve 3 has a circumferential groove into which the prongs of a fork et pass. The fork 4 is pivoted as at 5 to a bracket of the loom frame and has an' extending arm 6, held downward normally under the influence of aspring 10. The fork is operated to slide the sleeve 3, and pinion 1 on their shaft 2, by a cord 7, connected to an angle lever 8 pivoted in the loom frame adjacent the angle lever a6. The angle lever 8 is operated by cord 9 attached to a pawl operated by the pattern wheel u.

On the cam shaft f above the shaft 2 and to one side of the normal position of the pinion l is keyed a mutilated gear or cog wheel y the tooth section of which is adapted when the pinion 1 is slid on its shaft 2 to engage with the pinion and thus turn the shaft 2. The cog wheel y has teeth on only one-half its surface and when in engagement with the pinion 1, turns the same one-half a revolution for one-half a revolution of the cam-shaft f, the pinion remaining at rest for the succeeding half revolution of the cam shaft.

Secured to the shaft 2 is a stop disk 11, having on its periphery two diametrically opposite flattened portions. A crank pin 63 is fixed to this disk 11. The slotted end of a lever 12, pivoted centrally to a bracket on the frame, is connected at its other end to a link 13, which in turn is pivotally secured to a block 14 secured adj ustably to one arm of an angle lever 15 pivoted on a bracket of the loom-frame. The other arm of the angle leverl is pivotally secured to a link 16,0011- necting said angle lever with the crank arm '17 of the rocking shaft 18.

Resting on the edge of the disk l1 is a brake 21 held in contact with said disk bya spring 22. (See Fig. 5.) This brake serves to check the revolution of the disk ll and shaft 2 when it rests on one of the flattened portions of the disk.

The operation is as followsz-When the swivel shuttles are required the pattern wheels are rotated by the Jacquard mechanism and through the intermediate connections the forks u and t are beth operated simultaneously. The fork a throws the cam t over on the shaft f until said cam is above the arm w of the rocking shaft cu2. The cam t in its rotation will thus actuate the rocking shaft tu? and hence lower the swivel shuttle beam as heretofore explained. At the same time the shoes 0 are rendered inoperative through the arm w3, rods r and r2 and toggle lever r. The fork 4 throws the pinion l into engagement with the mutilated cog-Wheel y and thus sets the shaft 2 in motion. The disk 11 rotating with the shaft is turned one-half a revolution and through the intermediate connections shifts the swivel shuttles from right to left or vice versa. From the drawings it will be seen how in my present loom all of these motions co-operate with the motion of the fly-shuttle in weaving the ground pick of the fabric. For instance when the gear wheel y is meshing with the pinion 1 the cam t is depressing the arm tu of the rocking shaft 102 and is thus lowering the swivel shuttles; at the same time the shoes 0 are thrown out 0f engagement with the tappets q. In other words when the ily shuttle is at rest the swivel shuttle beam is lowered and the swivel shuttles actuated.

We will follow the motion of the loom when the swivel shuttles are required. The shoes 0 are thrown out of alfgnment with the picker tappets e and hence no pick of the fly shuttle takes place. At the same time the cam t depresses through the arm w and rocking shaft m2 the swivel shuttle beam to bring the swivel shuttles in position for weaving and when so lowered, the swivel shuttles are thrown from right to left or left to right as the ease may be to make one pick of swivel weaving. The beam is then raised by the action of the springs w7, this being permitted by the rotation of the cam t, the shoes o swung back into their normal position and the swivel rack actuating mechanism brought to a stand still by virtue of the fact that the plane surface of the cog-wheel y has passed over the teeth of the pinion l. One pick of the tly shuttle then takes place and the cam z in its rotation immediately thereafter actuates the shoes o and swivel shuttlebeam as before described and the teeth of the cog-wheel y again mesh with the pinion l to operate through the intermediate connections the swivel shuttles from left to right or right to left to make a second swivel pick.

ternate fly shuttle and swivel shuttle picks continues until the Jacquard mechanism indicates by releasing the forks u and et that no further swivel weaving is required. When The succession of al? IIO the forks u and 4 are released they assume their normal position under the influence of their respective springs and the cam t and pinion I are returned to their normal position on their respective shafts.

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