T0 ALL WI-IOM IT MAY CONCERN: y

Be it known that I, T. HENRY TIBBLES, of Kansas City, in the county of Jackson, and State of Missouri, have invented a new and useful Improvement in Hand-Looms; and I do hereby declare that the following is a` full, clear, and exact description thereof, 'which will enable othersskilled in the art to make and use the same, reference being had to the accompanying drawings, forming part'of this specification, in whiehi Figure 1 is a longitudinal vertical section of my improved loom, taken in the line are, fig. 2.

This invention relates to improvements in an ordinary hand-loom, and consists in a new. device for operat-x ing the drivers and throwing the shuttle by themotio'n of. the lay, with one `upright picker-staff and a shifting weight, .and working the heddles by direct action of the lay, without treadles, through the medium oflcam rollers, and also so 'constructing the lay that it may be removed without taking down the loom, as hereinafter particularly described. Only such parts of the loom are represented in the drawings, and herein described, as are essential to my improvements. y.

A represents the framing of a common loom, in which B are the heddles, C the lay, D the breast-beam, and E the yarn-roll or beam; all of which part-s are constructed and arranged in the ordinary way. On the front side of the cross-baril of the lay C, an upright picker-stad` or rod, a, is pivoted at its lower end, and to the upper end of the stai are fastened cords or straps b .71, that pass right and left, and are connectedvwith the shuttlesdrivers d c?, on each side ofthe loom. The upper end ofthe staff a moves in a guide, e, and on the lower end is attached a shifting or sliding weight, g, connected by a cord or strap, 7L, with the breast-beam D. The tendency of the weight -s always to rest in that end of the slide-bar t' that is the lowest, and whenthe lay is pushed forward freni the breast-beam, the strap It, acting on the weight resting in the lower end of the bar, draws up that end' vof the slide-b'ar-z', causing the upper end of the sta-ff' to move sdewise, and draw one of the straps b, and thus act on one of the driversdto throw the shuttle in one direction, and while the lay is being pulled backward towards the breast-beam, the strap i is relaxed, and the weight g slides down the bar z' to the opposite end,

which is the lowest, and holds the picker in position to beagain operated by the lay when it is next moved forward, andA thus move the other block and shuttle. This device is simple and effective for throwing the shuttle with every movement ofthe lay backwards and forwards. v My second improvement is an arrangement forworking the heddles B by the direct action of the lay with cam-rollers, thus dispensingwith treadles for springing the'fwcb or shedding the warp. For this purpose rollers K K are hung under the bottom of the heddles B, transversely, upon a cross-frame, F, on which rollers are placed 'cams m m, one or more under each heddle at each'end, for lifting the heddles successively to shed the warp,'instead of treadles in the usual way. To turn the rollers lc 7c, the levers u n are loosely fitted on their axes at onevcnd, '-.i'hich earrypawls s s working in ratchet-teeth on their ends, and the levers n n are worked by means of 4a horizontal bent lover, q, pivoted on the stud w to the eross-frame F, with which the levers are connected by rods o' r, as shown in the drawings. iOne ofthe rods, r, is fastened to the upper end of the lever "n, and the other rod to the lower end ofthe opposite lever. The bent lever q is also conncoted at one end by the rod t", with the back of the lay in such manner that the motion of the lay shall vibrate thebent lever to and fro, and thus act on the levers n 1t, one of the rods r pushing and the other pulling the levers,l and thus turning' the cam-rollers and lifting both ends ofthe heddles simultaneously as desired, according to the position o the cams.

A third improved device of my invention is making slots, u it, in the lower end of the swords G G, in which pins v o, on theframe of the loom, are inserted to support them, upon which pins the lay can rockinstead of on a shaft or4 rock-bar, the object of which arrangement is to allow the lay to be taken readily out of the'loom without taking it down. l

Having described my improvements in hand-looms, what I claim as new, and desire tosecure byvLetters Patent, is v i 1. The single upright picker-stall` a, the sliding weighty, and tlie straps 6 a-nd z, in combination with the layC, the breast-beam D, and .the drivers d d, constructed, arranged, and operating substantially as and for the purpose described. v 2. The cem-rollers 7c, operated by the. bent lever q, as descrilied, in combination with tlie heddlcs B und che lay C, operating as and for the purpose herein specified. t T. HENRY TIBBLES.
