W. GROMPTONS. FANCY POWER LOOM.
N0. 491. Patented Nov. 25, 1837.
UNITED STATES PATENT OFFICE.
WILLIAM CROMPTON, OF TAUNTON, MASSACHUSETTS.
FIGURE POWERrLOOM.
Specification of Letters Patent No. 491, dated November 25, 1837.
To all whom it may concern:
Be it known that I, WILLIAM CROMPTON, of Taunton, in the county of Bristol and State of Massacl'lusetts, have invented certain Improvements in figure, or fancy power-looms, by means of which improvements the power of extending and varying the figure is greatly increased, while the required changes therein are much facilitated; and I do hereby declare that the following is a full and exact description thereof.
Figure 1 is a perspective view of the whole .n'iachine, A, A, being the frame B, the breast beam and C the lathe; together with which other parts of the loom are represented, which do not need description, not being new.
D, D, are the jacks which operate the harness, of which, with their corresponding levers, D, D, there may be any desired numbers.
E, E, is the apparatus by which the jacks are thrown out. In the drawing it is represented as in the form of a cylinder, consisting of six bolts, or rods, runnin from end to end, and having on them shi ing rollers which project from them, and come into contact with the jacks throwing them out as required by the pattern, one of these shifting rollers is seen at a. Fig. 2 shows one ofthese bolts with the rollers on it, a, a, )eing the rollers which are slid on to the bolt, and are retained in their places by tubes placed between them, which also slide on to the bolts and are made of such length as are required to keep the rollers in their proper places. When a larger number of changes are required than can be obtained from placing the bolts, with their rollers, aroundasingle cylinder, they are so arranged as to form an endless chain of bolts and rollers, which pass around a cylinder situated like that represented, and alsoaround another placed below it, as otherwise conveniently situated.
The only ofiice performed by the rollers above described is the throwing out of the jacks, the lifting and depressing being effected by an apparatus for that especial purpose, to be now described.
F, is a lifting rod, which extends across the jacks D, D, and catches under the offset, or projection, 79, 6, upon them when they are thrown out, and as it rises, raises them and their levers.
G, is a similar rod for carrying those in place.
j a clks down which are not raised by the first rot.
' II, is the sliding bar to which the rod F is attached, the operation of which will be best seen in Fig. 3, which is a backview of" the loom. In this figure, I is the driving shaft, the cranks J J of which work the lathe, K, is a crank for working the lifting and depressing rods of the jacks. This crank is connected to the slide bar K by means of the shackle bar L, which it raises and lowers, as it does also the sliding bar .H, carrying the lifting rod F, there being two pulleys to communicate motion from one to the other as seen in the drawing. The wristof the crank K may be made to shift.
The shaft M, regulates the action of the shuttle and also that of the apparatus which throws out the jacks, N, is a ratchet wheel fixed upon the shaft, and O, is a stirrup or draw catch, which is jointed on to the upper end of the lathe, and as this is made to vibrate by the cranks J, J, the stirrup catches a new tooth on the ratchet wheel, and carries the shaft M, to the required distance.
The bevel wheel P, Fig. l, is on the end of this shaft and into this gears the small bevel wheel. Q, upon the shaft of the roller cylinder, and it will be seen therefore that this cylinder may have the proper motion communicated to it at every beat of the lathe. The two notched wheels R, R, on the shaft hi, are for working the pick and throwing the shuttle. As the lat-he vibrates, the projecting part of one of these wheels comes into contact. with a bell crank which throws the pick, as in some other looms, while at the opposite end one of the notches clears the crank, and so on alternately. The spring S, which presses upon the lower levers T, T, serves to bring them regularly On the end of the shaft M, there is a check wheel U, having as many depres sions on its periphery as there are teeth on the ratchet wheel, into which depressions the curved end of a spring passes to hold the shaft steady during the intervals of motion.
Fig. 4 is an end view of this check wheel and spring and Fig. 5 one of the jacks with its offsets for lifting and depressing.
What I claim as my invention, and wish to secure by Letters Patent is-- 1. The entire manner of constructing and eoinloii'ling the appnruti'is for working the ten dollars into the .lreasu1:'y of the United jacks as herein described, eonsistingessemfwtnlies, agreeably to the requirements oi the lielly of the lifting and depressing rods; the mat of Congress in that case made and prol .)(lH with rollers for throwing out the jacks, ruled.
