SWIVEL-LOOM.

SPECIFICATION forming part of Letters Patent N o. 467,262, dated January 19, 1892.

Application filed June 24, 1891.

To all whom it may concern:

Be it known that I, WILLIAM J. LUTTON, of Paterson, in the county of Passiac and State of New Jersey, have invented a new and useful Improvement in Swivel-Looms, of which the following is a specification.

My invention relates to an improvement in swivel-looms, in which provision is made for operating the swivel-shuttles at the moment the vibrating lever which communicates rnotion to the swiVel-shuttle-operating mechanism carried by the swivel-shuttle-supporting beam reaches either end of its stroke.

The improvement is particularly adapted to use in connection with looms of the dropbox type, in which the swivel-shuttle beam is allowed to fall to bring the swivel-shuttles into position for use at the same time that the drop-boxes are lowered to throw the shuttles therein out of use, and is an improvement upon the general structure shown and described in my patent, No. 460,477, granted September 28, 1891.

A practical embodiment of myinvention is represented in the accompanying drawings, in which- Figure 1 is a view ofthe loom in front elevation, partly in section. Fig. 2 is a partial plan view ot' the swivel-shuttle-actuating mechanism and its connection with the main shaft.. Fig. 3 is a view of the same in side elevation, partly in section. Figs. et, 5, and 6 are views in side elevation, partly in section, showing thethree positions whichthe vibrating operating-lever may assume with respect to the parts intended to be operated thereby. Fig. '7 is a partial horizontal section through the swivel-shuttle beam, taken on line a: of Fig. 13. Fig. 8 is a similar view taken on line y y of Fig. 13. Fig.`9 is asimilar view taken on line ,a .z of Fig. 13. Fig. 10 is a partial vertical longitudinal section of the swivelshuttle beam. Fig. 11 is a transverse section through the swivel-shuttle beam, taken on line w w ot Fig. 10. Fig. 12 isasimilar View taken on line o v of Fig. 10. Fig. 13 is an enlarged transverse sectionA through the swivelshuttle beam, taken on line u u of Fig. 10; and Fig. 14 is a partial enlarged transverse section through the swivel-shuttle beam, taken on line t t of Fig. 10.

carrying a drive-pulley d2, to which power is l applied from any suitable source.

The mechanism carried by the swivel-shuttle beam for imparting motion directly to the swivel-shuttles is connected With the actuating mechanism supported in the loom -frame and under the control ot' the dropping of the shuttle-boxes to throw it into and out of connection with the drive-shaft D by a lever E, pivotally secured to one of the lay-swords at e and having its upper end connected with the mechanism carried by the swivel-shuttle beam and its lower end engaged with the actuating mechanism driven by shaft D.

My invention contemplates the prompt swinging of the lever E, no .matter at which end of its stroke it be when the shuttle-boxes drop, and the movement of the swivel-shuttles in the right direction, no matter at which end of their strokes they may have been left.

The shaft D has ixed thereon a wheel F,

provid ed with pins or studs f, projecting laterallytherefrom atintervalsalongitsmargin. In the present instance four such pins are shown at equal'distances apart, adapted to engage the radial slots f in a wheel Fof the crossof-honor type and thereby impart to the said wheel F and to the shaft f2, on which it is fixed, a continuous variable rotary movement. The shaft f2 has fixed thereon a cam-wheel G, provided with a cam-groovegin its periphery adapted to receive the stud g on the laterallyvibrating lever G', the latter being pivotally secured at one end, as at g2, to a cross-piece a2, and its free end reaching forwardly and resting on the surface of an enlarged portion 7L of a longitudinally sliding and rocking shaft H, mounted in suitable bearings in the frame A. The shaft H is provided with a loop h adapted to receive the lower end of the lever E hereinbefore referred to, and to cause it to vibrate together with the longi tudinal movement of the shaft H, and at the same time permit said shaft to rock without disturbing its connection with the lever. The enlarged portion h of said shaft H is pro- IOO vided wit-h a pocket h2, adapted to receive the free end of the vibrating lever G' when the latter is at one limit of its stroke at the time the shaft II is rocked, and thereby form a' connection between the said shaft Il and vibrating lever G to cause the said shaft Il to be slid longitudinally by the vibratory movement of thelever. The shaft I-I is also provided with a crank h3, connected by a rod h4 with the drop-box frame, so that as the dropboxes fall the shaft H will be rocked. lf then it happens that the vibrating lever G be at the limitof its stroke to correspond with the pocket h2 in the enlarged portion h of the shaft II at the moment the drop-boxes fall, there will be a prompt engagement of the lever G' with the shaft II by the entrance of its end into the pocket h2, so that the said shaft, and hence the lever E and hence the swivel-shuttle mechanism connected with the lever E, will be promptly actuated. Such a position of the parts is represented in Figs. l and 2. If, however, it shall happen that the drop-boxes fall when the vibrating lever G is at the opposite end of its stroke, the rocking of the arm H would no longer engage the end of the lever G' within the pocket h2. In order, however, to secure an engagement with the lever G, which shall still slide the shaft II in the same direction as it would have been slid had the lever G' engaged therewith at the opposite end of its stroke, I provide the following mechanism: An operating-lever E is pivotally secured at e to one of the lay-swords a and has a pin-and-slot engagement at its lower end with the shaft ll. To its upper end is pivoted the upwardlycurved end 1l of a bar I, the body of which is intended to rest in proximity to the upper face of the vibratinglever G. An upwardlybent arm 'i' at the free end of the bar I has a vertically-movable engagement in a bracket a3, fixed to the lay-sword a and serving as a guide for the free end of the said bar. A notch 112, formed in the under side of the bar I, is adapted to receive the free end of the vibratinglever G when the said bar is allowed to drop at the moment the lever G is opposite the said notch. The bar I is held normally suspended by means of an arm h5, fixed to the shaft Il, which extends under a projection h, extending laterally from an auxiliary swinging arm hl, intermediate of the ends of the latter, the free end of the arm h7 forming a support for the bar I. From this it follows that when the shaft Il is rocked by the dropping of the shuttle-boxes the arm h5 will be rocked downwardly into the position as shown, for example, in dotted lilies, Fig. 5, and if at this moment the vibrating lever G be opposite the notch 'i2 the latter will receive the said vibratinglever and the bar I will thereby be moved longitudinally, together with the lever G', and such movement of the bar I will, through the connection of said bar with the shaft Il, move the shaft H in an opposite direction from that in which the bar I moves.

If therefore the vibrating lever G be at the opposite end of its stroke from thc pocket hZ when the boxes fall, it will be engaged with the bar l and the shaft II will be thereby moved in the same direction as it would have been had the lever G engaged with the pocket h2 at the opposite end of its stroke. When the lever G is engaged in the pocket h2, the bar I will rest on the upper face' of the lever G. To prevent the bar I from dropping into position to engage the lever G as the latter moves past the notch t2, I provide a guard hs, fixed to a cross-bar h4 and in position to receive a projection 3 on the back of the bar I and prevent it from dropping while the lever G is passing the notch.

The three positions which the lever G and the bar I may assume with respect to the shaft H and to each other are represented in detail in Figs. 4, 5, and G, the position in Fig.

4 being that in which the bar I is dropped into engagement with the vibrating lever G', and the latter being at the opposite end of its stroke from the pocket h2 will ride on the periphery of the enlarged portion h of the shaft Il, the projection t3 on the bar I being brought sufficiently low to pass underneath the guard hs. The posit-ion shown in Fig. 5 is that in which the lever G is engaged with the pocket h2 in the shaft II, the bar I being now held upon the upper face of the lever G and the projection 5. being in position to en; gage the upper side of the guard h8 when the lever G passes t-he notch in the bar I. The position shown in Fig. 6 is that in which the swivel-shuttle mechanism is out of action, the shaft ll being in the position which it assumes before the drop-boxes are let fall, the bar I being held supported by the arms h5 and hl, as hereinbefore set forth.

From the above it follows that if the lever E occupy the position represented in Fig. l it will be operated in a direction to throw its lower end to the left and its upper end to the right, no matter at which end of the stroke of the vibrating lever G the drop-boxes be let fall, and if the said lever E were in the opposite position from that shown in Fig. l, with its lower end to the left and its upper end to the right, it would be thrown in the opposite direction at the moment of the fall of the drop-boxes at either end of the stroke of the vibrating lever G.

The swivel-shuttles are represented by K K K2 K3. In the present instance I have shown a bank of four longitudinal series, the shuttles in one of the longitudinal series being represented by K and those in each of the other series by K K2 K3, respectively. They are operated by means of pinions 7c h', duc., engaged with rack-bars L L', dce., each longitudinal series being provided with its own independent rack-bar for operating that series. Each of said rack-bars has its own independent uprising standard l l', dac., connected at its lower end with the bar, preferably by means of a bar-sprin g M M', dsc., the spring IOO IIO

being fixed at one end to the rack-bar and the standard being secured to the free end of the spring, the tension of the spring tending at all times to holdthe standard depressed.

' Located within the swivel-shuttle beam and above the bank of shuttle-driving rack-bars L L', &c.,are located a pair of lower rackbar sections N and N' and a pair of upper rackbar sections O and O. The upper and lower sections N O and N' O' are spaced from each other and are adapted to engage the teeth on opposite sides of pinions P P', mounted upon axles secured tothe swivel-shuttle beam. The rack-sections N N' are connected by four bridge-pieces n n', dac., and the upper sections O O' are connected by four bridge-pieces, 0' 0', dac. The four connecting bridge-pieces of the upper and .lower rack-sections are intended to correspond to the four independent rackbars in engagement with the four longitudinal series of swivel-shuttles. The standards Z Z', &c., connected with the independent rackbar sections, extend vupwardly through the swivel-shuttle beam in proximity to the edges of the bridge-pieces n' n', &c., and o' o', &c., and said standards `are provided with projections Z4, extending laterally therefrom and adapted to engage within notches or recesses 'n4 and 04, formed, respectively,in the edges of the bridge-pieces of the lower and upper racksections. The notches niin the lower bridgepieces are covered by thin plates 'm5, so that when the standards Z Z', dac., are elevated to bring the projection Z4into one of the notches n4 in the lower bridge-pieces it will be prevented from passing on through said notch and will be held by said platein engagement with said lower bridge pieces. The lower bridgepieces n' fn', dac., are narrowed at points n, (see Fig. 8,) so that when such narrowed portion is opposite one of the uprising standards Z the projection Z4 on said standard will pass freely beyond the lower bridge-piece and into engagement with the notch o4 in one of the upper bridge-pieces. Oneof the upper or lower rack-sections-in the present instance, the lower rack-section-N' is connected by an arm Q with the notched loop R, fixed to the sliding bar r, engaged with the upper end of the lever E so that when the swivel-shuttles are dropped the said lever will be connected with the lower racksection N', and will causeit to move in one direction or the other, according as the lever E is moved in one direction or the other. The longitudinal movement of the rack-section N and the section N, connected thereto by the bridge-pieces n' n', &c., will cause a simultaneous movement of the upper rack-sections O O' in the opposite direction, because of the intermediate pinions P P', and hence any one of the independent rack-barsL L', &c.,vwhich shall at such time be connected by its standards Z Z', &c., with either the upper or lower rack-sections will be caused to'move in the direction in which said sections are moving, and motion will thereby be imparted to the swivel-shuttles in an opposite direction thereto.

Whether one or more of the longitudinalv series of swivel-shuttles shall be brought into operation at any one time may be determined by the pattern in the well-known Jacquard mechanism', not shown herein, but arranged to lift upwardly upon any one or more of the standardsZZ', as may be desired. The connection of the Jacquard mechanism with the standards Z Z', 85o., may be direct, and to this end the upper ends of the said standards are provided with perforations for the attachment thereto of connecting-springs S. I prefer, however, to employ a parallel motion-such, for example, as that shown in Fig.10, in which a horizontal finger s is connected by a pair-of parallel bars s with a support s2, fixed to the beam, the upper bar 3' being provided with an eye s3 for the attachment thereto of the spring S. The standards Z Z', dsc., are each provided with a laterally-projecting pin s, (see Fig. 13,) adapted to rest on the linger s, and thereby cause the standards to rise with the lifting of the finger. The pin s4 is adapted to enter a vertical groove S5, which communicates with a horizontal groove s, in which the pin s", when the standard is elevated to bring its projection into engagement with the lower bridge-pieces n n', &c., rides throughout the longitudinal movement of the rackbar, said groove S5 terminating in a mouth at the top of the beam to allow the pin to ride along the top edge of the beam when the said standard has been elevated to bring its projection intoengagement with the edge of the upper bridge-pieces o' o', dac. The variation in the amount of upward movement of the standard to engage the lower or upper bridge under the uniform lift by the Jacquard mechanism is accounted for by the spring connections S.

If the shuttles in any one of the longitudinal series rest at the left-hand ends of their strokes, their operating rack-bar will be at the right-hand end of its stroke. If at this time the lower rack-section be in the position indicated in Fig. l0, where the next stroke will be from left to right, the uprising standard Z' of the rack-bar to operate that series of sh-uttles will be in position, when lifted, to pass the lower bridge-piece and engage with theupper bridge-piece, so that the movement of the lower rack-section to the right and the consequent movement of the upper rack-sections to the left will move said rack-bar having the standards Z' to the left and the several shuttles of that series to the right vIl" at the s ame time the standard Z2 be lifted, it i will be 1n position for its projection to en-` gage the notch in the lower bridge-piece, andf,

it and its rack-bar connected therewith will be moved, together with said lower rack-sec-v tions, to the right, and the shuttles of that: series will be consequently moved to theleft. From this it follows that at whichever end of 'L their stroke the shuttles of any series be left,
