SPECIFICATION forming part of Letters Patent No. 610,711, dated September 13, 1898. Application filed April 2, 1898. Serial No. 676,165. (No model.)
To all whom it may concern:
Be it known that 1, JOHN KILLARS, acitizen of the United States, residing at Stonington, in the county of New London and State of Connecticut, have invented certain new and useful Improvementsin Knife-Sled Motions for Plush or Velvet Looms, of which the following is a specification.
This invention relates to an improved motion for the knife-sled of plush and velvet looms by which a positive and steady motion is imparted to the knife-sled, and thereby the reliable and even cutting of the pile fabrics made on this class of looms obtained.
The invention consists of an improved knife-sled motion for plush and velvet looms, which will be hereinafter fully described in detail and finally pointed out in the claims.
In the accompanying drawings, Figure 1 represents a sectional front elevation of a ,cated below and somewhat in front of the crank-shaft a and supported in bearings of the supporting-frame F of the loom. The teeth of the gear-wheels a a are so proportioned that while the crank-shaft a makes two rotations in looms making two picks the shaft 1) makes one rotation. ,To the shaft Z) is keyed a bevel-wheel c, which meshes with a bevel-wheel d, that is keyed to a short shaft 6, which is supported at right angles to shaft Z) in suitable bracket-bearings e at the inside of the frame F. Tothe opposite end of the shaft is applied a crank f, which is connected by a connecting-rod g with a wrist-pin h on a segmentally-toothed wheel R. The wheel R is keyed to a shaft 1", turning in bracketbearings 1 at the outside of the frame F. The wheel R is toothed at its lower part and placed in mesh with a pinion i, which is keyed to a second shaft j, that is supported in a sleeve-shaped bearing j. On the front end of. which isapplied a cord-pulley 0. The shaft n and the bearing j of shaftj are supported on a laterally extending bracket F of frame F. Around the'cord-pulley 0 is wound a cord 0 by which the knifesled p is operated in its guideways pfrom one side of the loom to the other, according to the reciprocating motion imparted to the same by the motion-transmitting cranks and gear-wheels. The cord 0 is guided from the cord-pulley 0 over pulleys 0 0 at one end of the guideways of the knifesled p and over pulleys 0 and 0 at the opposite end of the guideways and from the pulley 0 across the loom back to the cord-pulley o, to which the ends of the cord are attached in any approved manner.
During one rotation of the crank-shaft a, which takes place with the first pick of the loom, the crank-shaft f makes one-half of a. rotation, moving from the point in the direction of the arrow to the point Z in Fig. 1. This motion imparts to the segmentallytoothed wheel R one-fourth of a rotation in one direction and brings the wrist-pin h into the position shown in dotted lines in Fig. 1. This motion is sufficient to impart to the shaft sufficient motion, so as to turn the cord-pulley o by the intermediate gear-wheel transmission on n sufficiently so as to move the knife-sled over to the right-hand side of the loom.
The return motion to the knife-sled is produced by the second rotation of the crankshaft a, which takes place with the second pick of the loom. The second rotation of the crank-shaft a imparts half a rotation to the crank-shaft f, so that it moves from the point Z to the point is, which completes thereby its.
full rotation and brings by the connecting rod g the segmentally-toothed wheel R back into its former position, imparting rotary reciprocating motion to the same. This motion moves by the intermediate gear-wheels m 'n the cord-pulley 0, the cord 0, and the knifesled p in opposite direction to its former motion, and brings thereby the knife-sled back to the left-hand side of the loom. The motion of the knife-sled may be adjusted to any width of loom by the wrist-pin h in a radial slot h of the segmentally-toothed wheel R, setting it nearer to or farther from the center of the same, or by changing the proportions of the gear-wheel m and pinion n and the size of the cord-pulley 0 in a manner well known to mechanics, so that the required re-. oiprocating motion of the knife-sledis produced.
By the knife-sled motion described a reliable and positive motion is imparted to the knife across the loom, so that a steady and reliable cutting action is exerted on the piles of the plush or velvet fabrics woven in the loom.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a knife-sled and its actuating-cord, of a knifesled motion, comprising an intermediate shaft, means for rotating it at one-half the speed of the motion-transmitting crank-shaft, an intermediate crank shaft, a bevel gear transmission between it and said intermediate shaft, a segmental toothed wheel, a connecting-rod between said crank-shaft and wheel, a cordpulley, to which the knife-sled-actuating cord is applied and intermediate gear-wheel transmissions between the segmental toothed wheel and the cord-pulley, whereby reciprocating motion is imparted to the latter and thereby the knife-sled moved across the loom to the other side and back again, substantially as set forth.
2. The combination, with a knife-sled and its actuatingcord, of a knife sled motion, consisting of an intermediate rotary shaft, means for rotating it at one-half the speed of the motion-transmitting crank-shaft, an intermediate crank-shaft, a bevel-gear transmission between it and said intermediate shaft, a segmental toothed Wheel, a connecting-rod between the crank-shaft and the segmental toothed wheel by which rotary reciprocating motion is imparted to said wheel, a pinion meshing with said toothed wheel, an intermediate gear-wheel transmission, a cordpulley driven thereby and guide-pulleys for the cord at opposite ends of the ways for the knife-sled, substantially as set forth.
In testimony that I claim the foregoing as my invention I have signed my name in presence of subscribing witnesses.
JOHN KILLARS.
