W. H. BRAYTON. LET-OFF MOTION.
No. 3,397. Patented Jan. 6, 1844.

WM. H. BRAYTON, OF WARREN, RHODE ISLAND.
WEAVING-LOOMFOR REGULATiNG THE DELIVERY or WARP FROM WARP-BEAMS.
Specification of Letters Patent No. 3,397, dated January 6, 1844.
and made part. of this specification, is a full and exact description.
0f the set 0, 7" motz'om-To one end of the yarn beam as represented in Figures 1, 2, 3, at and5 letterais fitted a tooth wheel 6 which gears into and works with a small.
pinion 0 (Figs 5,) attached to and concentric with a pulley c called the friction pulley. The said pulley-and pinion work loosely on a shaft (l supported by suitable stands 4 r. Around the circumference of said pulley is carried once or twice a band or strap 6 called the friction strap. One end of this strap is fastened to a rod h of iron or other metal.
The said rod passes through a hole in the bearing plate f and is secured and regulated at the other end by a thumb screw 9.
The other end 6 of said friction strap is connected and fastened as represented in Fig. 2made part of this specification (until otherwise mentioned the references will be made to Fig. 2 only)by the rod h to the lower arm of an upright lever 76 attached to the sword L of the lathe L by the bearing is as a fulcrum. The other armof said lever is jointed to the finger V attached to and let down from the shaft X which is supported by hearings on the lathe sword L and supports the fingers 'w to. To these fingers w 'w the flighter P is attached and kept in its place by screws. The fingers to to are equidistant from the middle of the flighter. i
The operation of the let off motion is as follows: The flighter, upon the reeds striking the cloth, vibrates about three-sixteenths of an inch, more or less, as the springs a a one each side the flighter bear less or more upon it. By this vibration the fingers w 'u) attached to the flighter cause the shaft X to turn a little on its bearings, moving-with itthe finger V. This finger carries forward the upper arm of the lever is which moving on its fulcrum 70 carries proportionably the lower arm to-l ward the friction pulley c pushingbefore it the rod it. By this movement the fric.
tion strap 6 is slackene'd and allows by the decrease or want of friction on the pulley the yarn beam to revolve until the flighter resumes its former position on the lathe,
when by the tightening of the strap the motion of the yarn beam is arrested until a new vibration takes place.
The friction pulley may be about 5 or 6 inches in diameter and thick enough for a seven-eighths inch wide friction strap. The groove on its circumference may be about one-fourth of an inch deep. i The pulley can be operated without any other resistanceto the strap that what is offered it, by, the mak it terial of which the pulley is formed; butl think it better in order to increase the fric The friction strap may be formed of any substance sufiicient to cause the necessary friction, but I think leather .is to bepreferred to any other.
The pinion of the friction pulley may vary in size from 1. to 3 inches in diameter,
according to the quality of the goods made.
The thinner the goods, the larger the pinion, the teeth being of the same size. The shaft upon which run the pulley and pinion may be about of an inch in diameter, and, for a loom calculated for yard wide goods, may be about nine inches long. The rods may be made of any metal of sufiicient tenacity and the levers of the same or of wood.
The rate of let ofi or the quantity of motion given to the yarn beam is regulated for the different kinds of goods by tightening or loosening the friction strap by means of the thumb screw 9, thin goods requiring the strap to be looser than thick ones.
What I claim as my invention is- The mode of connecting the yarn beam with the fiighter by means of the friction strap and pulley.
The let off motion can be applied to the fiighter in another mode and also to the spring whip roll stand, both of which I consider as modifications of the mode already described. It can be applied to the flighter as follows: The end 6 of the foresame effect.
mentioned friction strap is connected and fastened (Fig. 8) to the lower arm of the upright lever 70 by the rod h. The rod 71 after passing through said lever. 72 is secured and terminated by the thumb screw .7) which serves to regulate the length of said rod. The fulcrum of lever 70 rests on the horizontal bearing Z of the upright stand Z of the frame A. In the upper arm of said lever 72 through a hole near its extremity large enough to allow free play, is passed a rod m having a knob n at one end to prevent that end from going through the hole. The other end of this rod is secured to one arm of a horizontal lever O which has its other arm secured to the middle of the flighter P and its fulcrum upon the lathe L. The manner of the operation under this modification is as follows: Upon the vibration of the flighter as first described the lever 0 causes the rod m to move the lever is by drawing the knob 02 into contact with its upper arm. By the movement of said lever 76 the strap 6 is loosened in the same manner as described in No. 1, and with the As soon as the force of the flighter is expended, the rod m is pushed back and the lever 70 is left to resume its former position. The spiral spring J having been by the lever is in the loosening movement contracted and forced toward the stand Z is now freed from the propelling power and expands, forcing with rapidity said lever is to its place and thus tightens the strap. It can be applied to the spring whip roll stand in the following manner: The end 6 of the forementioned friction strap is fastened as in Fig. 4:, to the horizontal lever 10, attached at one end by a pivot and arm at to the frame A of the loom, and at the other is secured to and moves with the stand S. The mode of operation is as follows: By the vibration of the spring whip roll caused by the action of the reed upon the cloth, the lower end of the stand is moved in the opposite direction of that of the upper, and is forced in the direction of and with the spring Y until the impulse ceases, and carrying with it the lever 10 loosens the strap 6, so that the yarn beam is allowed to run until stopped by the return of said stand caused by the action of the spring Y upon it. The same result can probably be attained by variations in the sizes and positions of the different parts. The sizes and positions which I have given, I have found by experience to be sufficient for the purpose.
In testimony whereof, I, the said NIL- LIAM H. BRAY'roN, hereto subscribe my name in the presence of the witnesses whose names are hereto subscribed on the seventh day of July, A. D. 1841.
