Letters Patent No. 96,238, dated October 26, 1869.

IMPROVEMENT IN HAND-LOOIMS.

The Schedule referred to 'n these Lettera Patent and making partv of the same'.

Taall whom it may concern:

Beit known that I, ABRAHAM J oNns, of Clinton, in the county of De Witt, and in the State of Illinois, have invented certain new and useful Improvements in Looms; and do hereby declare that the following is a full,`clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.V

The nature of my invention consists in the arrangement of certain devices for operating vthe treadleshaft, and the device by which the treadleshaft is prevented from turning backward.

In order to enable others skilled in the art to which my invention appertaius, to make and use the same, I will now proceed to describe its construction .and operation, referring to the annexed drawings, which form a part of this specification, and in which- Figure 1 is a transverse vertical section,

Figure 2, a front elevation, and

Figure 3, a plan view of mymachine.

Figure 4 is a longitudinal vertical section of the shuttle-box Figure 5 is a plan view of the shuttle-binder; and

4Figure 6 is a side view of the gearing which operates the treadle-shaft.

A represents. the frame-work of my loom, at the front end of which, near the top, on the Ainner side, is pivoted a lever, B, 'one end of which forms the handle to operate the loom, and the other end, ,being bent downward, is, by means of a bar,G, connected with ar'arm, D, from -the main shaft E, at the rear end of the machine.

On the shaft E, is placed a pulley, F, which, by a cross-belt, is connected with and communicates motion to a pulley, G, placed loosely on the treadle- Shaft I.

.At the side of the'pulley G, on the shaft I, is placed a small wheel, ,-having four cogs, at equal distance apart, and on or in the side of said pulley is a springpawl, b, which operates in these cogs.

It will then be seen, that if the bent lever B is operated in the same manner as a pump-handle, at the upward stroke of the lever the pawl b will catchon one ofthe cogs of the wheel a, and turn the treadleshaft onefourth around, while, at the downward stroke, the pulley Gr will more independently of ,the shaft, so that the pawl will he ready at the next upward stroke to catch the next cog, and turn the shaft another ouefourth revolution.

'lo prevent the treadle-shaft I from turning backward when the pulley G does,I provide said Shaft, at one end, with -a smallratchet-wheel, c, in which a. pawl, d, works, so as to hold the treadle-sha-ft when vturned forward.

On the shaft I are placed the tappets H H, which vinches from the centre.

lwork the treadles J J when the shaft is turning, the

treadles operating the harness in the usual way.

To the ends of the main shaft E, fly-wheels K K. are secured, which wheels are, by means of u'ods L L,

connected with the batten, these rods being, on a full-.

sized machine, pivoted to the ily-wheels, about eight It will .be seen that the batten will move four times each revolution of the treadle-shaft.

A M is the top piece of the hatten, or hand-piece for l L working the hatten-back and forth, and receives the upper part of the reed N, the lower side of-which is held by the bar O.'

The bar O has a shuttle-bog, P, at each end, and

the shuttle passes over said har, from on'e box to the other.

When the shuttle enters Athe box P, it strikes a picker, Q, placed in the same, which picker, as it moves to the outer end of the box, operates the shuttle-binder R, pivoted in a slot on the -front side of the box', so that the shuttle will be held temporarily inthe box, but not so hard as to prevent it from moving inward again when force is applied to the picker.

The outer end of the shuttle-binder R is bevelled,

as shownin fig. 5, so as to allow the picker to move in'freely, and cause the inner'end of the shuttle-binder to hold the shuttle.

The picker is connected by a strap, c, which passes through an oblique slot Vin the bottom f the shuttlebox, with the picker-stad S, the lower end of which is pivoted to a cross-bar, connecting the lay-swords. The upper end of thepioker-staiil works in a slot-iu the bar T, under the hatten, above mentioned.

When the picker is moved outward by the shuttle,

the upper end of the picker-staff is, at the same time, by means that will bev hereinafter set forth, moved ontxvard, and is caught by a. trigger, V, on the under side of the barT.

The picker-stares S S are connected by a spring, X,

as seen .in iig. 2, so that when the trigger V, which holds its picker-stati', is operated, upon releasing said staff this spring forces the upper end of the stati inward, thereby causing the picker to throw the -shuttle through the shed. At the same time, the other staff, S, is drawn outward, to be, in like manner, caught by its trigger and released a'gain. j

Tile picker-stad is moved outward by a strap, f, which passes around a pulley at the end ofthe hatten. and is attached to a connecting-rod, Y, which is pivoted to the outer side of the tlywheel K, in a full-` sized machine, about four inches from the centre, the two connecting-rods being so placed as to allow the alternate motion of the picker-staves.

The trigv'er V is operated by a lever, Z, pivoted on backward and forward for A, so as to release the pickerstares lat the proper moment. This lever is operated by an eccentric, g, on the end of the treadle-shaft I.

AA' are the uprights of the battenvorking ou rockers B B', which are prevented from sliding by a pin inserted in a slot on the bottom bars of the frame.

The yarn-beam C' has a' pulley, D', around which is placed a rope or chain, attached. to a lever,E, which is pvoted` to the inner side of the frame, by which means the letting off ofl the warp may be regulated while weaving.

The cloth-beam F' is, at one end, provided with a 1atchet-wl1eel,h, and on the journal oi' said clotlkbeam is a crooked or bent lever, l, provided with a pawl, m, which catches in the ratchet-wheel on the take-up roller. The end of the lever l rests on and is worked by the hatten.

A spiral spring, n, attached to the under side of the lever l, forces the lever downw'ar again, winding thev cloth up on the beam.

To' this spring u' is attached a cord,.12, which passes around the pulley o, in the lower bar of the frame'A,

then upward to a pin, r, by which means the spring can be tightened or loosened at pleasure, thus regulating the rapidity with which the cloth is taken up.

To prevent the cloth from unwindin g from the clothbeam, a detent, i, is provided, which Works in` the ratchet-wheel h, for that purpose, as seen in fig. 1.

l have described many parts that are old; but

What Iclaim as new, and of my invention, and desire to secure by Letters Patent, is-

l. The lever B, connecting-bar O, arm D, main vshaft E, and lyavheels K K, all constructed as described, and arranged to operate the lay, substantially in the manner herein set forth.

2. The main shaft E and pulley F, connected by a cross-belt to the ratchet-pulley G on the treadle-shat
