Be it known that I, WILLIAM CRoMr'roN, of Taunton, in the county of Bristol and State of Massachusetts, have invented certain 11nprovements in the Figure or Fancy Power- Loom, by means of which improvement the pow-er of extending and varying therein are much facilitated; and l. do hereby declare the f'ollowing is a full and exact description thereof.

Figure-'1 is a perspective view of the whole machine, A Abeing the frame, B the breastbeam, and C the lathe, together with which other parts of the machine are represented which do not need description, not being new.

D D are the jacks 4 their corresponding levers D, there may be any desired number. It is obvious that other means may be resorted to for connecting the jacks with the harness without changing the principle of operation or construction.

E E is the apparatus by which'the 'jacks are In the drawingsit is represented as in the -form of a cylinder consisting of six bolts or vrods running from end to end, and

having on them shifting-rollers, which project from them and come into contact with the jacks, throwing them out as required by the `One'of these shifting-rollers is seen at A. Fig. 2 shows one of the bolts or rods, with the rollers on it at A A, being the rollersl which are slid on the bolts and are retained in their places by tubes placed between them, onto the bolts, and are made of such lengths as lare required to keep them in their proper places when a larger number of changes arerequired than can be obtained from placingthe bolts.withtheir rollers,around a single cylinder. They are so arranged as to for-m an endless chain of belts and rollers, which pass round a cylinder situated like that represented, and also round another placed below it. or otherwise conveniently situated. This apparatus is forl the purpose of controlling the position of the jacks in such a mauner that they shall be carried up or down by the lifter and depressor, giving such motion to the harness as the figure may require.

Re POWER-Looms.

l The modes above described of constructing l and arranging the details of thisguring apparatus 1 much prefer; but it is obvious that mere pins or projections at the points where the rollers are placed, whether on rods or on the-surface of a cylinder, or on almost any kind of an endless chain arranged to move, as above described, will -answer the purpose, though in an inferior manner without varying l theprinciple of operation. It will be also seen that this figuring cylinder or chain may with equal convenience be placedin front of the jacks. 1t is represented as placed behind them. The only officev performed by the rollers on the chain is the throwing out of the jacks, the lifting and depressing being effected by an apto be now dc- F is alifter which extends across the jacks D D, vand catches under l tions b b upon them when they are thrown out, and as it rises raises them and operates the harness.

G is a depressor attached to slide rod K', for carrying those jacks down which are not raised by the lifter F..

H is 'a sliding rod, torwhich attached, the operationot" which will be best seen in Fig. 3, which is a back view of the loom. In this figure, 1 is the driving shaft, the l cranks J J of which work the lathe.

K is a crank for working the lifter and depressor of the jacks. This craukis connected tothe slide-rod K' by means ot` the shacklebar L, which it raises and lowers as it does t also the sliding ma and the depressor G in opposite directions, there being two pulleys to communicate motion from one to the other, as seen in the drawings. The axis of the crank K may be made adjustable.

The modes of elevating and depressing the lifter and depressor which 1 prefer to all others; but they may be di'erently operated as every skillful mechanic' can readily see. instead of being connected with a sliding rod at one end they may be each connected with such a rod at .both ends. They may also be connected by arms to arock-shaft l and vibrate in the arc of a circle, or they may the lift-er F is the offsets or projecl H, carrying the lifter ;F
