Letters Patent N o. 107,313, dated September 13, 1870.

IMPROVEMENT IN MECHANISM FOR OPERATING THE PICKERS OF LOOMS.

The Schedule' referred to in these Letters Patent and making part of the same To all whom 't'tvma'y concern Be it known that we, ELIAS A. WAREIIAM and WILLIAM H. WAeGoNnIt, of Kirkville, in the county of Wapello and State `of Iowa, have invented a new and useful Improvement in Hand-Looms; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the'accompanying drawing forming part of this specification.

My invention relates toloolns, and consists of .an improvement in connection with the picker-staff, which will be hereinafter described in connection with all that is necessary to a full understanding thereof, and then clearly specified in the claim.

Figure 1 represents a front view ot' our improved` loon., partly in elevation and partly in section.

Figure 2 represents a sectional elevation, taken on the line x :e ot'ig. l.

Figure 3 is a plan view of one of the shuttle-boxes; and

Figure 4 represents, in front and side elevations, anl arrangement of cams for producing cloth twille-d on b'oth sides, suoli as we propose to usc in substitution of those represented in the machine, and to adapt for being readily so changed.

Similar letters 'of reference indicate eorrespomling parts.

A represents the race-beam of the lay, and

B, the sword-arm, arranged in the usual way.

Gis the picker-stati", arranged at the center, and connected by cords D to the pickers E, so as to operate b oth. y

This stati' is pivoted at F to a suitable support 1"*- ing up from the ii'ame, and is considerably enlarged around the pivot to support'thc pins G and the cam*- shaped project-ion H, to be acted on by the doublehooked and pointed end I ot' a bar, K, connected at L to the Iace-beam, so that, by the movement of the said beam back and forth, the hooked end of the said plate has a slight rising andfalling movement upon the enlarged part of the picker-stati, between the pins and against the cani projection acting alternately on each side ofthe said cam projection, and against the pins.

having been Inoved last to the right, whereby the point c of the cam projection is moved to the left, so that when the point I4 Inoves down again at the forward movement of the lay it will lbe carried, by its point acting on the right side of the point a of the cam, to the right, so as to engage the hooleb under the right-handv pin G, whereby, when the lay is moved back, the npwardmovement ot' the bar K will throw of the bars X, extending from the heddle-fi'ame to In the drawing, iig. 1, the stati" is represented ,as

the staff C over to the left, and, on the next downward movement of the said 4bar K, the pointed end will be carried down the left side of the point a of the The cam-shaft M is provided with a hooked wheel,v

N, having as manyhooks as there are cams, and this wheel is acted upon by a pawl, O, connected to the Arear side of the lay-beam, and arranged to move forward on the said wheel whenv the lay moves back to engage by a hook or pin with one of the hooks of the ,said wheel N -for turning it forward when the lay moves forward.

To this cam-shaft, which I propose to arrange in its hearings, so as to be readily removed for the substitution of other shafts with other arrangements of cams, for instance, that represented in iig. 4, I couple on, in'any preferred way, a short extension, 1, running to the outside of the frame, where it is provided with a crank, Q, and connecting-rod or pawl It, adjustably connected to the said crank by a slotted bar moving the wrist-pin back and forth.

' This pawl engages, at the other end, with the ratchet-wheel S, 'on the cloth-beam, by which the lat ter is moved for taking up the cloth.

For the purpose of producing a uniform action ot' the cams on the hcddle-frames U, which work in vertical guides V, and must necessarily stand each in a dilierent plane relatively to the plane of the axis of the cam-shaft,'I provide shoes, XV, at the lower ends the cams.

These slices are of uniform length, and all arranged in the same relation tothe axis of the cam-shaft, whereby the rise and fall of each heddle-frame will occur in the same order in respect to the movement of the cams or other parts of the loom.

The tension of the warp-beam Y is produced by a friction-brake, consisting of a lever, grooved at one end to tit the periphery ot' afriction-rim, Z, on the roll,` and connected by a pivot-joint, Z2, to the frame, the other end being provided with a temper-screw, Z, passing through it, and screwing down upon said end to increase the friction on the rim Z, or to release the same by unscrewing to allow the brake to rise.

Below the breast-beam we have arranged a wheel, A', with pointed teeth, to press against the cloth as it Inoves from the breast-beam to the take-up roll, so as to be turned by the cloth. v

The outer end of the shaft of this wheel is provided i with a single tooth, B2, gearing with Ia large toothed wheel, C', which may have a greater or lesser number of teeth, anda scale graduated to the teeth and the wheel A', in any preferred way, so that the number of yards wound upon the roll can be ascertained at any time from the said scale.

The shuttle-binder consists of a round block, b, iig. 3, let into a recess in the side of the shuttle-box, and connected to a spring, l1, so secured inthe said side that the blockwill he pressed through the opening of the recess into 'the shuttle-box snficently to press the shuttle when received into the box against the opposite side. Y

These blocks are slotted at b, and pins are arranged in the box to rise up through the slots, so as to control thc blocks against the tendency of the shuttles to force'the blocks in the direction ot' their movement either way, while allowing them to oscillatcifreely to and from the race. x

Having thus described our mventionl' n Te claim as new and desire Yto secure by Letters Patent- VVit-nesses: WM. H. WAGGONER.
