POSITIVE SHUTTLE-MOTION FO'R LOOMS.

SPECIFICATION forming part of Letters Patent No. 320,902, dated June 23, 1885.

Application filed September 29, 1883. (N model.)

To all whom it may concern.-

Be it known that we, FREDERICK K. WRIGHT, CHARLEs W. GAGE, and WILLIAM F. HITCHCCCK', citizens of the United States,

residing at Homer, in the county of Cortland and State of New York, haveinvented certain new and useful Improvements in Positive Shuttle-Motions for Loo-ms; and we 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.

Our invention is an improvement in positive shuttle motions such as areemployed in looms for weaving wire and other cloth.

It consists, chiefly, of a pair of picker-staffs for moving the shuttle-carriers, which are united to the said shuttle-carriers by ribbons, said staffs being moved laterally by means of levers pivot-ed on a bracket secured to the beam of the lay or beater, connecting arms or rods between the said levers and pickerstaffs, bars provided with cam-grooves fixed to the loom-frame, and arms or rods guided upon 2 5 the lay-frame, connected with said levers, and

provided with projections or rollers fitting into said cam-grooves, all of which will be set forth hereinafter.

In the drawings, Figurelis a sectional view of a portion of a loom, showing the shuttle motion in elevation. Fig. 2 is a plan View showing the shuttle operating mechanism. Figs. 3 and 4 sh 0w details of parts hereinafter described.

3 5 Referring to the drawings, A is the beam of the lay, provided at each end with plates a a, formed into loops a, which latter serve as guides for the shuttle carriers B B, and the curved rocker-arms F F of the picker- 0 staffs D D. The carriers B B have 1ongitudinal grooves d d on both sides, into which the tongues or projections e e on the opposing faces of the plates a and loops a extend, and serve as accurate guides for the carriers.

5 To the ends of the shaft 0, which forms the axis of motion of the lay, are pivoted on suitable clips or clasps,b b, the pickerstafi's D D, for operating the shuttle-carriers. Ribbons f f are secured adj ustably at opposite ends to the heels of the rocker-arms F F and the inner ends of the carriers, respectively, while similar ribbons, f 2 J, are secured adjustably to the toes of said rocker-arms and the outer ends of the carriers,respectively. The rocker-arms F F are united to the tops of the pickerstaffs, near the heels of the arms, so as to permit the said arms to reach inward across the machine to as great an extent as possible.

G is abraeket secured to the beam A of the lay, which serves as a bearing to ashaft which forms the fulcrum of shear-levers H H. To opposite ends of said levers are pivoted arms I I and rods K K. The picker-staffs D D have pivoted in the slots 0 the rodsKK,which latter may be adjusted in the said slots by any well-known and suitable means, to change the throw of the picker-staffs to suit circumstances.

To the ends of the arms I 1, upon suitable pins, are secured anti-friction rollers g g. Plates J J, grooved on their under edges, are 7c secured to the lay-beam A, and these plates, together with short extensions j on the arms I I, serve as guides to the latter as they are moved back and forth.

L L are bars formed with cam-grooves,which 7 5 are U-shaped in vertical transverse section, and have the general conformation shown in the drawings, said bars beingpermanentlyfixed to the upper horizontal beams of the loomframe and braced together by a rod, h. The SC grooved bars L L form races for the movement of the anti-friction rollers g g, and during the reciprocating or swinging movement of the lay the carriers B B receive the proper movement through armsI 1', levers H H,rods K K',picker-staffs D D and the ribbons uniting the rocker-arms F F with said carriers. I

Motion is given to the lay in the usual manner by cranks A on the main shaft A of the loom, and rods A, connecting the lay with or such cranks, and, as previously implied, the movement of the mechanism composing the shuttle-motion described is coincident with the movement of the said lay.

The shuttles to be used with our shuttle-mo- 9 tion are such as are adapted for use with carriers that alternately take hold of and release the same automatically-such, for instance,as is shown and described in the patent to F. K. W'right, No. 299,610, June 3, 188i. 1

The bars in which the cam-grooves are formed are so shaped that when motionis imparted to the carriers aslow impulseis given atstarting, which is quickened at the center of the stroke, and then retarded, so that the liability to concussion at the moment of change of the shuttle from one carrier to the other is obviated.

In Fig. 4 of the drawings we show the end of the rocker-arm F with a lug secured thereon, and the ribbon f provided with a screw threaded end and a nut, f. Said arrangement is for the purpose of tightening or loosening said ribbon as it is lengthened or shortened from any cause. A similar arrangement may be applied to the outer ends of the carriers B B, as indicated in Fig. 1.

Having thus described our invention, what,

we desire to claim and secure by Letters Patent is 1. The combination of the lay, the carriers, the flexible ribbonsff ff the rocker-arms F F, connected to the carriers by said ribbons, the picker-staffs D D, united to the rockerarms near the heels of said arms, and the camgrooved barsL L, with shear-levers H H, the connecting-arms I 1, secured at their inner ends to the tops of the levers H H, and at their outer ends being provided with the rollers g to enter the cam-grooves, and the connecting-rods K K, connected at their inner ends to the lowerlimbs of the lovers H H, and

at their outer ends to the picker-staffs, and means for operating the lay, substantially as and for the purpose specifie 2. The combination of the lay, the carriers, the picker-staffs, means for connecting the carriers and the picker-stairs, and the camgrooved bars L L,with the shear-levers H H, the connecting-arms I I, secured at their inner ends to the tops of the levers HH, and at their outer ends being provided with rollers g to enter the cam-grooves, and connecting-rods K K, connected at theirinner ends to the lower limbs of the levers H H and at their outer ends to the picker-staffs, and means for operating the lay, as and for the purpose set forth.

3. The combination, with the frame and can1- grooved bars fixed thereto, of the lay, the shuttle-carriers, the picker staffs, ribbons connecting the carriers and picker-staffs, and levers and rods, substantially as described, for imparting motion to said picker-staffs from the said cani-grooves'as the lay vibrates, as and for the purpose set forth.

In testimony whereof we affiX our signatures in presence of two witnesses.
