SWIVEL-LOOM.

SPECIFICATION forming part of Letters Patent No. 493,651, dated March 21, 1893.

Application filed May 20, 1891. Serial No. 393,475. (No model.)

To all whom it may concern:

Be it known that I, OTTO W". SOHAUM, of

the city and county of Philadelphia, State of Pennsylvania, have invented a certain new and useful Improvement in Swivel-Looms, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to that class of looms in connection with which what are known as swivel-shuttles are used; and particularly to mechanism for operating the swivel-shuttles.

In looms of the class referred to the swivelshuttles move in carrier-blocks which in turn are secured to the swivel shuttle supporting bar; the shuttles are provided with racks which engage with spur-wheels journaled in the carrier-blocks, and longitudinally-moving racks are secured in the swivel shuttle support, the motion of which racks causesthegearwheels to revolve and the shuttles to pass across the space between adjacent carrierblocks. The swivel shuttle support is secured in front of the reed and is made longitudinally-movable normally maintaining a position by which the swivel-shuttles are held above the shed but capable of being depressed sp as to bring the swive1-shuttles within the s 16d.

In the above-described particulars my loom is similar to those which are already wellknown in the art the construction being shown for instance in the patent to WVadsworth No. 338,891 of March 30, 1886.

The object of my invention is to provide improved means for operatingthe longitudinallymoving racks supported in the swivel shuttle support; and incidentally in connection with the improvement in connection with the rackactuating mechanism, to improve the mechanism for actuating the swivel-shuttle supporting bar.

The nature of my improvements will be best understood as described in connection with the drawings in which they are illustrated and in which,

Figure 1 is a side elevation partly in section of a loom provided with my improvements, Fig. 2 afront elevation partly in section of the same omitting the picking bowls and their actuating mechanism taken on section line 12 of Fig.1, Fig. 3 a plan view taken on the sectional-line 3-4 of Fig. 1 and showing the bowls and their actuating mechanism, Fig. 4 a .plan view showing the upper part of the swivel-shuttle supporting beam and mechanism connected therewith, Fig. 5 an enlarged sectional elevation through the swivel-shuttle support taken on the line 5-6 of Fig. 4, Fig. 6 a plan view taken on the line 7-8 of Fig. 3, Fig. 7 a cross-section taken on theline 9--l0 of Fig. 5; Fig. 8 a view of the swivel shuttle support showing the wayin which the lifters, hereinafter described, are rigged. Fig. 9 is an elevation of shaft- K and the mechanism connected therewith, Fig. 10 a sectional view showing the action of the litter, and Fig. 11 is a face view of the cam L A is the frame of the machine; B the warp beam; 0 the shed; F the harness; D the lay; E and E the take-up and cloth rolls.

I G is the swivel-shuttle supporting beam; G the swivel shuttles; G2 rods supporting the beam G and made vertically movable as shown; G springs operating to hold the rods and beam in their uppermost position; G links connected with across-bar G the ends, G, of which are secured to the rods G the springs G being situated between the ends G and bearings G8 attached to the lay swords G which are supported on the rock shaft G and through which bearings the ends of the rods G2 are permitted to slide; rings or collars G secured on the ends of the rods G limit their upward motion. The links G4 are attached to the end of a lever I pivoted at I and having a roller 1 journaled upon it which rests on a cam JJ', the function of which will hereinafter be described.

G are the carrier-blocks secured to the beam G and in which the swivel shuttles G move.

H represents the reed of the loom.

K is the shaft to which the cam JJ is keyed as shown at j; this cam is made up of two parts one, J, in the form of an eccentric which will, by depressing the lever I, draw down the swivel-shuttlesupport so as to bring the swivelshuttles within the shed,the other part, J, of circular form concentric to the shaft K and of such diameter as will not affect the lever I or tend to draw down the shuttles. The

arts Jand Jare secured to ether and keyed I o to shaft K so as to be longitudinally movable along it; they are provided with a collar J in which collar rests the yoke of a lever L secured to a longitudinally-movable shaft L journaled in bearings L L and connected to the end of a bell-crank lever L pivoted at L and connected at its other end with an arm of a lever L pivoted at L the other arm of which, marked L rests in the groove of a cam L". In addition to the fork lever L the rod L carries another similar fork lever L the ends or which rest in the collar R of a movable cam-section R the use of which will. hereinafter be described. The shaft K also serves to actuate the pick levers, the movements of which as well as the mechanism for throwing them out of operation when the swivel shuttles are drawn down to make a pick, are shown in Figs. 3' and 9; in these figures K and K indicate fork clutches secured to, and rotating with shaft K.

K K are hubs supported on shaft K, but

not secured to it, from these hubs extend.

arms K to the ends of which are secured the bowls K ward along the shaft K the arms K are engaged by forks K and caused to rotate with" the shaft, and in that position the bowls strike against and depress arms X which are secured to rock shafts X as are also arms X to the ends of which are attached straps X connected at their other ends with pick levers T T which actuate the ground shuttle in the usual way. It is necessary that the ground shuttle should be thrown out of operation when the swivel shuttles make a pick, I

and to secure this result in the plan shown I secure to shaft K by means of a feather j a cam J J .in general character like cam J J,

the arm W forked and engaged with a 001 lar K of the hub to the right of the drawings, while to the arm W is secured one end of a rod W the other end of which is attached to a forked lever W pivoted at o toabracket V and engaging at its other end the collar K of the hub K to the left. When the end of the arm W rests on the circular part J of the cam the bowls are in their outer position and engaged by the forks K but when the cam J J is shifted to depress the swivel shutties, the cam J J also shifts and at the same time as cam J acts to draw down the swivel shuttles, the cam J pushes up the arm W and, by the connections described, draws out of operation the bowls K The specific mechanism above described forms no part of this invention, but forms subject matter for another application filed May 12, 1892, Serial No. 432,720.

At this point I will also briefly describe the construction and operation of cam L which cam however, forms no part of myinvention,

When the hubs are moved outand is shown simply as one and a good device for actuating rod L.

Referring now to Fig. 11 it will be seen that cam L has two concentric groovesl and Z connected by grooves Z l as shown, and is provided with switches Z P, Z Z Z l; on each side switchesl and Z are attached to a rod Z which by means of a spring Z acting on an arm Z is normally forced out so as to hold the switches Z and Z in their outer position as shown at the top of Fig. 11, the bar 1 has a roller Z at its end, 1 is a shoe pivoted at Z and moved up or down by a cord Z actuated by the Jacquard apparatus. When shoe Z is drawn up the roller Z runs against it and the bar Z and attached switches are moved in as shown at the bottom of Fig. 11. Z is a runner adapted to move in the cam grooves and to which is attached the end L of the leverL L, the arm L of which en gages and actuates the lever L which in turn moves rod L. Normally the runner Z remains in groove Z but when shoe Z is drawn up and the switches moved as described it rides up on switch Z passing through groove Z and raising switch Z passes into groove Z in doing so of course moving rod L and as described shifting'the cam to bring the swivel shuttles into operation-and disconnect the ground shuttle 'pick levers.

Returning now to the swivel-shuttle supporting beam, M M indicate the longitudinally-movable racks of which two, corresponding to two rows of shuttles, are shown in the drawings; but it will be understood that any desired number from one up may be used. The racks M move in slots M formed at the bottom of the beam G and which slots are continued entirely through the beam at M M metal plates M slotted to correspond with the slots M are shown as resting upon the top of the beam G. To the center of each rack M a bar M is bolted, to'each end of which, bars M are pivoted at M M the free ends, M, of the bars M being bent upward so'as to extend through the slots M M the length of which slots correspond to the longitudinal motion of the racks M. The pivoted rods H M are the devices through which motion is communicated to the racks M. Wipers Q reciprocating over the slots M and the slots in plate M in such a way that they will not come in contact with the ends M of the pivoted levers M unless the said levers are pushed up into their paths and this elevation of the pivoted lever is accomplishedat proper times by means of a lifter as P which lifter is actuated at proper times by the Jacquard apparatus connected with the loom but not shown in the drawings.

Before describing the special construction of the pivoted levers, wipers, and lifters illustrated in the drawings I will call attention to the gear-wheels N-pivoted in the blocks G5 and which engage with the teeth of the racks M and with the corresponding teeth of racks N on the shuttles G. And I will also note that a spring 0 should be employed to hold the pivoted levers M downward at all times except when they are thrown up into operative position by the lifters.

As shown in the drawings it will be noted that the slotted plates M have recesses M on their inside ends and that a slot M is formed in the end M of levers M In the slot M is pivoted a latch M pressed outward by a spring M (see Fig. 7) so that when the lever M is lifted the latch M will, as soon as it has passed above the slot in plate M spring out and rest upon the plate M in which a corresponding slot is formed thus holding the lever M in the position to which it has been lifted and so that the end M will lie in the path of the wiper'Q which, moving inward, will carry with it the rod M and cause the rack M to make alongitudinal movement; as soon as the latch M comes over the recess M which it does at the end of the stroke of the wiper Q, the latch is no longer supported and the rod M is permitted to fall back to the position shown in Fig. 5.

Any convenient device for lifting the rods M may of course be used; that shown in the drawings consists of a bell-crank lever P pivoted at P and held in the position shown in Fig. 5 by springs P The ends 10 of the lifters rest upon or close to the racks M in normal position and so that they will be immediately under the pivoted rods M when the said rods are in the position which they occupy when the rack M is pushed over toward the lifter. Cords P attached, to the end p of the lifter P are connected to a Jacquard hook P as shown in Fig. 8 so that both lifters of each rack are actuated at the same time; of course only that one which is in contact with a pivoted rod M performs any work the other one moving idly; but by moving both together as shown the movement of any particular rack can be called for and insured irrespective of the position it occupies in the swivel-shuttle supporting beam.

Of course the lifters could be actuated i11- dependently but a valuable improvement is effected by their simultaneous movement. In Fig. 10 the litter is shown in action.

Referring next to the wipers Q, of which it is only necessary to employ two, one over each series of slots M I will state that the said wipers are supported on guides M and are given asimultaneous rec-iprocatory movement to and from each other. As shown the wipers Q are attached to rods Q pivoted at the ends of arms Q and which arms are secured to the ends of a pair of vertical rock-shafts Q Q supported on the lay swords; the rock-shafts are connected together by means of arms Q and Q united by rod Q and arranged as shown in Fig. 3 or so as to have an inverse reciprocatory movement. On the lower end of one of the rock-shafts Q (that to the left as shown) an arm Q is attached which arm is connected by a rod Q with a lever Q pivoted at Q and having a pin Q extending from it into the groove of a cam R R supported on the shaft K. As shown one part, B, of this cam is fastened to the shaft K, while the other part, B, is keyed as shown at r to it so as to turn with it but to be movable to and from the part R, the movement being effected through the collar R and the fork lever L when the two parts R and R are moved together the cam becomes operative and remains so actuating the wipers through the gearing described but as soon as the part B is moved away from the part B and the lever Q is moved out to the level of the high part of cam R the cam becomes inoperative and the movements of the wipers cease.

S indicates the main or ground shuttle of which there may be any desired number in the loom; T T the pick levers by which the ground shuttles are actuated.

From what has already been said the operation of my improved loom can be clearly followed. VVhene-ver it is desired to bring the swivel-shuttles into operation the cam L or other device is broughtinto operation so that acting through the lever L L upon the lever L and through the levers L and L upon the cams on shaft K the said cams are brought to operative position-the cam J acting through lover I and its connections draw down the swivelshuttle support G until the swivelshuttles are within the shed, and the parts of the cam R R closing and acting through the lever Q and its connections to give the inverse reciprocatory movement to the wipers Q. The swivel-shuttles being new in proper position and the wipers Q moving to and fro above the slots ll/FM the Jacquard apparatus is made to operate the lifters P at proper times throwing up one of the pivoted arms M into the path of one of the wipers which immediately comes in contact with it and through it effects a stroke of the rack and of the swivel-shuttles actuated by that particular rack. It will be seen that the different lines of swivel shuttles may, if desired, move simultaneously in different or the same directions and that any particular line can be called upon independent of the others; also that the form of the cam J may be such as will hold the swivel-shuttles in operative position while they make several strokes or such as will cause them to move up out of the shed after each stroke so that the ground shuttle may be thrown across through the shed before the swivel-shuttles are again brought into operative position. In fact, by my apparatus almost any desired arrangement of picks of both the swivel and ground shuttles may be effected.
