'IO ALL WHOM I'l MAY CONCERN:

4Be it known that I, H. D. HUNT, of Danville, in the county of Vermillion', and State 'of Illinois, have invented a new and useful Improvement in Lboms; and I do hereby declare that the following is a full, clear,

and exact description thereof, which will enable others skilled in the Vart to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- 'Figure 1 is a top view of a loom with a part of the lay removed to show one part of my invention.

Figure 2 is a front view of the lay with the breast-beam removed, showing my improvements.

Figure a vertical cross-section, taken Vin the line :v x, tig. 2.

Similar letters of reference indicate corresponding parts.

This invention relates to improvements in hand-looms, and consists in connecting movable plates and levers attached to thelay with the breastfbeam and shuttle-drivers in such manner that the movement of the lay shall operate on the drivers to throw the shuttle; and also other'devices connected with the take-up of the clothbeam, and the working of the treadles and yarn-beam, hereinafter .moreparticularly described.

A represents the lframeof a common hand-loom, B the vbreast-beam, C the lay, D the cloth-beam, E the yarn-beam, F the treadlecam shaft, and G the treadles. In the lay C, on each side ofthe middle, a segmentalplate level', II, is pivoted in a slot in the lay at b, iig. 1, and having on opposite sides projecting arms c c', one, of whichVV arms e projects through the slot on the front sideof the lay, and is connected by a cord, a, with the driversI to throw the shuttle; `and the other arm e', which projects from the slot on the back side of the lay, is connected with one end of the spiral springs d, the other end of which springs is fastened to the frame ofthe loom, the otlice of which is to draw the segmental-plate levers H quickly when it is tripped, as hereinafter described, and thus act on the drivers Ito throw the shuttleto the o pposite side.. On the front side of the lay are two long curved 'levers e e, extending from side to`-side, pivoted at opposite ends to the lay atgg, and connected at their otherends to springs h z, fastened to the lay. Each of the levers is provided with an arm, z', that projects upward to catch in a nick, k, in the side of the segmental-plate lever H when it is drawn Vthrough the lslot by thev hook m attached to the breast-beam B, and catching on the knob n when the lay is Vpushed forward'. The levers e e are constructed andarranged to operate in such a manner that they shall' alternately' project the arms i' t' into the nicks lc k in the segmental levers H H by the forward motion of the lay, to hold them until. the return or back movement of the lay shall trip the arms and release the segmental levers, when they are drawn back by the springs dal to operate on the drivers I,L as horeinbefore described, thus,

by the motion ofthe lay, driving the shuttle automatically instead of employing the right hand of the weaver tn do it in the usual way.'

It'will'be observed that when the lay is pushed forward one of the hooks m will catch on the knobs n, and draw the segmental lever H through the slot to the front side of the lay, when the back edge of the segmental lover will bear upon one of' the l'ong -levers e, and depress its end connected with the spring l1., by which depression of the lever the arm z' on thevsame lever will.be withdrawn from the nick c in the other segmental lever H to trip it, and allow the spiral spring d todraw it back quickly, and operate the driver with which it is connected; and thus by every movement of the lay forward and back this operation will be repeated alternately by the segmental levers H and thc'long levers e e to drive the shuttlesin the opposite boxes automatically.

At the lower end of one of the swords K' is attached an adjustable pawl, @that works the ratchet-wheel p* on the cloth-bea`m D. The pawl pis adjusted by a handfsc-rew, 292,10 regulate the take-up of the cloth enl tbe'bcam. On the back side of the lay C isattached a rod, o, connected with a meta-l collar, r, placed on the trcadle-cam shaft F to move it around a certain distance by means of the pawl s, .working in a slot in the colla-r when the lay C moves back to the breastfheam". The treadles G are held up in position by an inclined spring,`

t, under their ends when the dcpresser c on the sword K is drawnfrom their points by the back movement of' the lay. Under the yarns-beam E is placed a'brake, w, curved to lit it, which is adjusted by a set-screw, w', to tighten the beam and regulatel the tension of the warp, instead of the ordinary weight and pulley.

AIIav-ing'th'us described my invention, what I claim asnew, and desire to secure by Letters Patent, is `1.- 4The segmental leversV H, pivote-d to the lay C, in.combinatiou with the long curved levers e, the hooks m, the springs d, the cords g, and the drivers-I, constructed, arranged, and operating substantially as and for the purposes herein described.

i 2. The-adjustable pawl p and screw p2, connected with the lathe, and in combination with the ratchet-wheel pl on the cloth-,beam D, arranged and operating as and for the purpose specified.

The above specification of my invention; signed ,by me this 11th day of March, 1867.
