ISHAM SEDGWIGK, OF RICHMOND, INDIANA.

WIRE-TWISTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 233,033, dated October 5, 1880.

Application filed August 20, 1880. (No model.)

To all whom at may concern:

Be it known that I, ISHAM SEDGWICK, a citizen of the United States, resident at Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Wire-Twisting Machines; 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 or figures of reference marked thereon, which form a part of this specification.

This invention relates to machines for making twisted-wire fabrics; and it consists in certain improvements upon a machine for the same purpose described and shown in Letters Patent No. 218,323, granted to meAugust 5, 1879, which improvements will be hereinafter fully described, and particularly pointed out in the claims.

Figure 1 is a front elevation of a machine embodying the improvements in my invention. Fig. 2 is a sectional plan view taken below line 1 l in Fig. 1. Fig. 3 is a sectional plan view taken between lines 2 2 and l l in Fig.1. Fig. 4 is a sectional plan view taken between lines 3 3 and 2 2 in Fig. 1. Fig. 5 is a detail view of a portion of the wire-shifters. Fig. 6 is a detail view of the perforated shifting-bar, its rack and pinion. Fig. 7 is an end view of the expansible reel, and Fig. 8 is a sectional detail view of a portion of the machine, show ing the wires and the fabric formed therefrom. Fig. 9 isa view, in elevation, looking toward the side on which the mechanism for operating the rolls is located.

Referring by letter to the drawings, A designates the frame of the machine; 13, the master-wheel, which revolves in a horizontal plane, is toothed in its periphery, and is provided on the upper face of its rim throughout half of its circumference with studs 0, D, E, and F at intervals of forty-five degrees.

At the left-hand side of the frame is a short vertical shaft, Gr, supported in bearin gs G G and provided with an arm, H, and a tappet, I, secured thereto at angles of thirty degrees. On the right-hand side of the frame and nearer the front of the same is a vertical shaft, J,

awhich extends from the bottom to near the top of the frame A, and is provided nearits lower end with arms J J Thearms H and J have wrist-pins J and are connected by a pitman, K. The arm J has a wrist-pin, and is connected by a rod, K, to wrist-pin of an arm,K upon a short vertical shaft, L, on the same side of, but near the rear of, the frame. The shaft L also has a tappet, L, secured at an angle offsixty degrees to the arm K On the left-hand side of the frame, and slightly in the rear of the short vertical shaft G, is another short vertical shaft, M, slightly longer than the shaft G, which is provided near its lower end with a four-pointed star-wheel, M, and at its upper end with a pinionwheel, M At the other side of the frame A, and directly opposite the shaft M, is a long vertical shaft, M extending from the bottom to near the top of the frame A, provided near its lower end with a four-pointed star-wheel, M and a pinion, M corresponding in position with the star-wheel M and the pinion M upon the shaft M. The long vertical shaft M is also provided at its upper end with a pinion, M.

A rack-bar, N, having racks N N on opposite edges at its ends, works in ways N N, at opposite sides of the frame A, the racks engaging opposite sides of their respective piuions, as shown.

The upper end of the shaft J is provided with a horizontal miter'gear wheel, J which engages with a vertical miter-gear wheel, 0, upon a horizontal shaft, 0, traversing the frame laterally between its girders. Arms 0 O are keyed to the shaft 0, and are connected, by curved pivoted bars 0 O, to the frame 0 of the wire-shifters P.

The Wire-shifters P consist of plates slotted at P in their inner ends, and beveled at P upon each side. These plates P are bolted in pairs to the upper and lower faces of the bars of the frame 0 so that they embrace the bed P in which the wire-twisters P and their operating racks P I? operate. Half-shifters I are necessary, one at each of two corners, at opposite ends of the frame 0 for convenience.

The construction and operation of the twisting-disks P and the racks for operating them are the same as those shown and describedin my former Letters Patent, hereinbefore mentioned, except that two rack-bars are used to operate the twisting-disksviz., one on each side thereof, as shownand the mechanism for driving the rack-bars is differently arranged. In this instance the pinion M on thelong vertical shaft M operates the rack-bars P P.

Outside of the master-wheel B, and near the front of the frame A, are arranged two vertical shafts, Q Q, provided at their lower ends with pinions Q3 Q, the teeth of which engage the teeth of the master-wheel.

At the upper ends of the shafts Q, Q are crank-wheels Q Q and beneath the crankwheel Q} on the shaft Q, is a pinion, Q which engages a gear-wheel. Q on the lower end of a vertical shaft, Q.

Upon the cross-beams R of the frame A are secured two flat plates, It It, placed parallel to each other, and having a space, R between their inner edges. Upon these plates R R are secured metal cleats R made concave in their under faces, and beveled inward and downward at the edges, to form ways R in which the flanged spool-carriers R slide back and forth across the space It.

Flanged plates S are secured to the outer sides of the cross-beams It of the frame A, to form guideways for the carrier-frame S, composed of the grooved end bars, S and the connecting side bars, S S, between which the spool-carriers R ride.

The carrier-frame S is provided with studs '8 upon its bar S which are connected with the wrist-pins S on the crank-wheels Q Q by pitmen 3 S Beneath the plates R It bars T traverse the frame A, between thecross-beams It, andhave a space between their inner edges which registers with the space 1%, between the inner edges of the plates R B A perforated bar, T having a rack, T, on its front edge and near one end thereof, works in ways T T secured to the under faces of the bars T, directly beneath the space R in front of the perforated rack-bar T a vertical shaft, U, provided near its upper end with a gear-wheel, U, which engages with the rack T is suspended in bearings, and provided at its extreme lower end with a fivepointed star-wheel, U

The master-wheel B is provided with eight curved radial arms, U U U U U" U U U the arms U U U U being provided, respectively, with studs V V V V which travel, when. the master-wheel B is revolved, in a circular path outside of the vertical shaft U, and strike the arms of the five-pointed starwheel U and cause it to turn in the samedirection as the master-wheel B, which revolves in the direction of the arrow.

The arms U" U U U are provided, respectively, with studs V V V V, which travel, when the master-wheel B is revolved, in a circular path inside of the vertical shaft U,

' and strike the arms of the five-pointed starwheel U and cause it to turn in a direction the reverse of that in which the master-wheel B is movin At the upper end of the vertical shaft Q is a horizontalmiter-gear, W, which engages with a vertical miter-gear, \N, on a horizontal shaft, W, at the upper part of the frame A.

Upon the top of the frame A, and directly over the twisting-disks and wire-shifters, is arranged a system of three rollers, X X X supported in bearings X X, and connected by gear-wheels X X X.

The shaft Y of the roller X projects beyond the end of the frame A, and is provided with a ratchet-wheel, Y, and an arm, Y carrying on its inside a pivoted pawl, Y A pivoted detent, Y at the side of the frame A, also engages the ratchet-wheel Y.

The outer end of the horizontal shaft W carries a crank-wheel, W A slotted pitl'nan, W, pivoted to the upper end of the arm Y connects with the wristpin W on the crankwheel W An expansible reel, Z, provided with a pulley, Z, is supported in bearings at the rear side of the frame A. This reel consists of a shaft, 0, provided with cross-arms b, to which slotted plates 0 are secured by screws d. The. slats e forming the reel are secured to the slotted plates 0, two to each plate, as shown,

and the reel is expanded by turning nu'tsf 5 upon the shaft to, so that the innerends of the plates 0 will rest on the corners of the nuts. The wire fabric is wound upon the reel while in its expanded condition, and when the fabric is to be removed the nuts are turned to permit the reel to contract, when it can readily he slipped from within the roll of fabric upon it.

Near the rear of the frame, and beneath and in the rear of theperforated shifting-bar T is located the spool-rack g, for carrying the supply spools h, on which are wound the edge wires and a portion of the intermediate wires, of which the fabric is formed. The remainder of the intermediate wires are wound upon the supply-spools t placed in the spool-carriers R.

The wires from the spools h are passed up through the perforations in the shifting-bar T through the space R between the plates R R the edge wires passed through the eyes in the two outside twisting-disks, P and the intermediate or mesh wires from both sets of supply-spools carried up and placed in the notches in the opposite sides of each alternate twisting-disk P thence between the rollers X X, and between the rollers X X and down around the reel.

At the left-hand front corner of the frame is a short vertical sh aft, 70, having a gear-wheel, l, at its lower end, which engages the gearwheel Q upon the shaft Q, and at its top with a horizontal miter-gear, m, which engages the vertical miter-gear 42 upon the inner end of the pulley shaft 19, through which motion is studs 0, D, E, and F on the rim of the masterwheel are nearest the front of the frame and between the star-wheels M an d M when starting, the stud C willfirst strike one of the arms projecting inward from the star-wheel M and l turnit one-quarter revolution to the left, which twisting-disks P and turns the twisting-disks to the right. The studs D, E, and Ffollow, and cause theparts above mentioned to be operated by each studin like manner until the twistingdisks have made two revolutions to the right. The spool-carriers R are, at the start, over the plate It, on the front side of the space R the shiftenbar T is at the limit of its movement toward the left of the machine, and the wireshifters P are shifted to the rear limit of their movement. The stud (J on the rim first strikes the arm of the star-wheel M, as above stated. The studVon the arm U then strikes the outer arm of the five-pointed star-wheel U (the spool-carrier frame having in the meantime carried the spoolcarriers R across the space R, over to the plate R through the pinions Q Q crank-wheels Q Q and arms S and the starwheel U makes one-fifth of a revolution to the right, and shifts the shifting-bar T to the right. The stud D then, and at about the same time, turns the star-wheel M one-fourth revolution to the left, the spool-carriers R are drawn back across the space R and the stud V on the arm U strikes the inside arm of the fivepointed star-wheel U then in its track, and shifts the shifting-bar T to the left. The stud E almost immediately thereafter strikes the arm of the staravheel M, then in its track, and turns said star-wheel M another fourth-revolution to the left. At the same time the spoolcarriers R are again shifted over the space R to the plate R and the stud V on the arm U strikes an outer arm of the five-pointed star-wheel U and causes the shifter-bar T to be shifted again to the right. The stud F immediately thereafter strikes the fourth arm of the star-wheel M and turns it again to the left, the stud G striking the tappet L just as the stud E leaves the star-wheel M, and operating through the arm K bar K, arms J J on shaft J, pitman K, arm H, gearing J and O, shaft 0, and arms 0 O to operate the shifting-plates P, causing them to shift the mesh-wires from the set of twisting-disks P, that they then occupy, to the notches in the opposite twisting-disks, and at the same time causing the tappet I to be turned inward to come in the track of the stud O. The stud 0 next strikes the inner arm of the star-wheel M at the right-hand side of the frame A, and turns the star-wheel M onefourth revolution to the right, and carries the rack-bar N to right. The pinion M at the top of the shaft M is also turned to the right, and operates the racks P P in such a manner as to turn the twisting-disks P to the left. The stud V on the arm U next strikes the outer arm of the five-pointed star-wheel U and a second time shifts the shifting-bar T to the right, its last movement having been in the same direction, which shifts said bar T to its limit to the right. The spool-carriers R are at this time shifted over the space R to the plate R and the stud V on the arm U now strikes an inner arm of the five-pointed star-wheel U and shifts the shifting-bar T to the left. The stud next follows, striking an arm of the fourpointed star-wheel M, which is again operated to the right, the twisting-disks turned to the left, and the spool'carriers drawn again to the front of the space E The stutl V on the arm U next strikes an outer arm of the fivepointed star-wheel U and shifts the shiftingbar T to the right, where it is a second time at its limit to the right. The stud E next strikes the star-wheel M the spool-carriers R are shifted to the plate R and the stud V on the arm U strikes an inner arm of the fivepointed star-wheel U and shifts the perforated bar T to the left. The stud F strikes the starwheel M turns it the fourth time to the right, the spool-carriers R are returned to the plate R, the stud V on the arm U strikes the inner arm of the star-wheel U and shifts the bar T to the left to its place of beginning, as herein described, and the stud G strikes the tappet I, throws the tappet L in the track of thestud O, and shifts the shifters P to the rear of the frame, where they started.

The foregoing describes the operation of the mechanism, except the rollers and reel,during one complete revolution of the master-wheel B. The rollers are operated during this time by the pawl to press the fabric between them, and the reel is operated to wind it up as it comes from the rollers. The reel is operated by a band leading from a pulley on the shaft of the roller X.

The fabric formed on this machine is simi-' lar to that formed on my former machine described in the Letters Patent hereinbefore mentioned, and it consists ofa fabric having edge wires and diamond shape mesh Work, and tension-wires in the mesh-work, if needed. The twisting-disks are the same and operate in the same manner.

The shifting-plates P being placed in pairs, one plate of a pair being above and the other below the twisting-disk, the wires are shifted from one set of disks to the other and back again with greater regularity and precision than where only an upper set of shifters are used, as in my former machine.

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

1. In awire-twistin g machine, the perforated shifting-bar T provided with the rack T supported in ways beneath the space R in combination with the shaft U, carrying the pinion U at its upper end and the five-pointed starwheel U at its lower end, and the masterwheel B,provided with studs V, V,V ,V V V V and V", constructed and operating substantially as and for the purposes set forth.
