TO WHOM IT -MAY '.CONCERN:

' Be it known that we, THOMAS G. THOMPSON and BARCLAY BALLARD, of Richmond, Indiana, have invented certain new and useful Improvements in IIau l-Looms and we do lhereby declare the followingtov be a. full, `clear, and exact description of the same, reference being had to the drawings whielraceompany this specification,

and to the letters of reference marked thereon.

In the drawings our improved loom is represented in perspective.

The nature of our invention' consists in the construction of a hand-loom, simple, cheap, and eifective, capable of doing every variety of work at a greatly reduced price,and not liable to get out of order by use.

A A represents vthe framing of a hand-loom of ordinary construction, in which F F are the betten-posts, and E the race or cross-piece connecting the posts F F, and all together forming the hatten. In most looms, the bottoms of the posts Fare connected by across-rail, which rests in bearings on the side rail A. In other looms, pins or short shafts project from each rail A, and enter holesfin the bottoms oi' the posts. These pins are liable to be bent, and often become loose, and thus cause the hatten to rest and workunevenly. The brackets K are made of metal, have al square opening in them to receive the free ends of the arms F. These arms are pivoted in these openings on pins J, that have bearing at both ends in the bracket; and these pins or pivots serve for bearing for the lay-arms, and are held securely in a true horizontal position, and insure a properand even action of thelay. The hatten is so hung in the brackets K K, that when it is thrown back to the herldle-franie B B, the race-board E has an inclination downward and backward from the operator, and this obviates the disposition or inclination of the shuttle in its transit to iiy its track and break the warp. m m are guide-straps attached to the open ends of the shuttle-boxes respectively, and serving to press the shuttle backward and downward when entering or leaving the shuttle-box. The shuttle-honestT N are each provided with vshuttle-head blocks, to which are attached the throwing-cords y g, to the centre of which cords the handle G is secured, the right I and left motion of which by the hand of the operator actuat'es the shuttle. The trcadles 1 2 S are operated by Vthe feet of the operator, and are constructed and hungin the ordinary manner, and properly attacheddto the heddles, which are operated by the treadles aforesaid. The cloth-beam D is operated by a takeup lever, H, and the pawls 5 6 working a ratchet-wheel, (Z, secured to the end ot' the shaft or beam D. The warp-beam L is properly arranged to rcvolvevin the back end oi' the upper side rails A A, and is provided with a spur-wheel, J. The spur-wheel J'is rigidly attached to the warp-beam L, between one of its heads andthe beam-bearing, and revolves with the saine. The let-off lever I traverses the length of the side piece A, being pivoted thereto at z', und provided with a segment at its rear end, which is fitted into the cogs ofthe wheel J, and is held there b y the action of the .stop 'i'. v The warp, being wound upon the warp-beam, is carried forward over the roller-shaft C, and through the harness and reed, and attached to tbc cloth-beain D in the ordinary manner, and is tightened up by the operation of the take-np lever II on' the right hand oi' the operator, while with his left hand grasping' I the handle of the lever I, he raises it suieiently to let oil' the warp as may be required. The let-od' and the Vtake are thus at the control of tlieopcrator rigidly and exactly.

Among the advantages which we claim for our improved loom are, simplicity and durability of construction, being coniposed of fewer pieces, and produced at less cost than. any other hand-loom known to us; the brackets K K, as a. superior method of pivoting the lower ends of the hatten-posts; the arrangement and operation of the levers H and I, and their connections, for governing the tension of 'the warp the arrangement race, by which the shuttle is kept in fpinee during its transit, and the use of the guide-straps m m as auxiliary thereto.

Having thusfnll-'y described our said improved loom, what we claim as new, and desire to secure by Letters Patent, is

1. The brachctsK K, in combination witli the hatten-'posts F F, pivots J, and the side rails A A, all con- .strn'eted and arranged as herein deseribed,

2. The combination of the warp-beam L, spur-wheel J, pivotcd let-*off lever I, rack z', stop T, cloth-beam D,

ratchet-wheel d, take-np lever II, and pawls 5 and 6, when constructed, airangcd, and operating as and for the purposes herein set forth and described.
