LOOM.

SPECIFICATION forming part of Letters Patent No. 435,565, dated September 2, 1890.

Application filed January '7, 1889. Serial No. 295,665. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN KENNEDY, a citizen of England, residing at Paterson, Passaic county, State of New Jersey, have invented a new and useful Improvement in Looms, of

which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to mechanism for changing the weaving in swivel-looms from plain weaving wherein the fly-shuttle is used exclusively to plain and swivel weaving combined, wherein the fly-shuttle is restricted in its movement and swivel-shuttles are introduced to form figures in the fabric. Usually this change from plain weaving to plain and swivel weaving combined has been effected by an endwise movement of the cam-shaft in looms.

from plain weaving to plain and swivel weaving combined requires devices somewhat complicatedin their construction-as doublegrooved cams, a beam carrying studs to enter the grooves in said cams, face-cams, &c.

which, owing to their complexity, are somewhat uncertain in their action, and are therefore objectionable.

The object of my present invention is to provide means for changing the weaving in swivel-looms from plain weaving to plain and swivel weaving combined which shall possess the advantages of the former mode of making such change, but which sh ll be free from its objectionable features.

3 5 My invention consists in certain features of construction and combination of parts, as will be hereinafter fully described, and pointed out in the claims.

Figure 1 of the drawings shows in elevation one end of a swivel-loom of ordinary build with my invention attached. Fig. 2 is apart front elevation of the same. Fig. 3 shows in elevation the opposite end of the loom with my invention thereon. Fig. 4 is a rear elevation of the loom with my invention attached. Fig. 5 shows in section a portion of the cam-shaft, sleeve, gear, &c.,on line Z Z of Fig. 4, detached. Fig. 6 shows in detail a portion of the changing devices in the posi tion which they occupy when the movement of the fly-shuttle is restricted and the swivel- This mode of changing the weaving shuttles are in operation. Fig. 7 shows the parts of Fig. 6 in the position which they occupy when the fly-shuttle is in full operation and the swivel-shuttles are at rest. Fig. 8 is a detail of cam, treadle, &c., part sectional, on line X X of Fig. '7; and Fig. 9 is a modification of certain parts shown in Figs. 4, 6, and 7.

A represents a swivel loom of ordinary 6o build, having the usual drivingshaft a, crank Z), arm 0, lay d, cam-shaft K, warp and cloth beams f, e, and h, cog-wheels R R and SS. The loom, which is constructed as is usual, need not, it is thought, be further described herein. 7

In bearings that are arranged in the loomframe is journaled a shaft B, to move length wise, on one end of which shaft a lever F is mounted to rock, and on the other end a lever F is also mounted to rock, while inward on the shaft B from the lever F is provided a notch E.

The lever F on the shaft B is adapted to be engaged by a roller j, arranged on the cogwheel R and lever F, by aroller j,arranged on an arm of the cam-shaft K, the action of which rollers upon the levers is adapted to give an inward movement to thepickingsticks j j by means of the usual straps and curved arms to throw the fly-shuttle 0 across the loom, which sticks are returned by the action of springs j j in the usual way.

The notch E, arranged in the shaft B, is adapted to receive and accommodate a pawl 8 5 E on the frame a, arranged for such engagement with the notch E. An arm B is fastened at its top to a shaft B", while the arm B at its lower end is connected with an arm B which latter is connected with an arm B,

.one end of which is fixed on the shaft B,

Fig. 1.

To the arm B one end of a spring B is fastened, the opposite end of which latter is fastened to the floor. To the arm B is also 5 fastened a cord B that passes over pulleys B B one of which is fastened to the frame A and the other to the floor, while the cord B is attached to the jacquard or other pattern mechanism, not essential to a full under- I00 standing of my invention, and therefore not shown in the drawings.

lhe shaft 13 with which the arm B is connected, is mounted in hearings on the frame A, is adapted to be moved longitudinally by the arm B as hereinafter stated, and has mounted on it treadles B and D, which treadles are in turn adapted to be acted upon by cams D 0 as hereinafter stated.

The cam D is fixed on the cam-shaft K, while the cam C is made integral with a sleeve 0 mounted loosely on the cam-shaft, and which has also made integral with it a cog-wheel 0 that engages and is actuated by a cog-wheel G which latter is integral with a cog-wheel C, that is mounted on a stud C fixed in the frame A, which last-mentioned cog-wheel C meshes with and receives its motion from a cog-wheel C, fixed to the shaft K, Fig. 5.

To the lay-sword d is fixed a lug B, to

which is pivoted a lever B to the upper end of which lever is pivoted a link B which latter connects with a rack-bar 0 while the lower end of the lever B is connected with a horizontal bar B the inner end of which bar is connected with the treadle B by means of a cord 13, and also is connected, by means of a spring C, with the lay d, as shown. To a horizontally-arranged bar D, connected by a cord Diwith the treadle D, on which the cam D can act, are fixed by jamnuts vertical rods D D, which rods are arranged to slide through lugs, that are fixed to the lay d, and which rods are each surrounded by a spring D, the rods being connected at the upper ends with the swivelrack in the usual way.

The cog-wheel S, which is loose on the camshaft K, should be four times as large in diameter as the cog-wheel S, with which it gears and from which it receives its motion, namely, to make one revolution to every four revolutions of the wheel S on the drivingshaft 0.. The sleeve 0 revolves around its axis in exact conformity to the cog-wheel S that is, it makes one revolution to every four revolutions of the wheel S, while the camshaft K makes two revolutions to every one revolution of the sleeve O and cog-wheel S. By this arrangement of speed of the cog-Wheels S S, sleeve 0 and shaft K the fly-shuttle 0, operated from the wheel R and cam-shaft K, and the swivel-shuttles C", actuated by cam O and the wheel S, in point of time move alternately across the loom without interference.

So that the above movements will be clearly understood, I will now describe how the several picks are made successively, the loom being adjusted for swivel-weaving and the observer being supposed to stand in front of the loom. The fiy-shuttle is supposed to be at the right-hand end of the shuttle-race. Both picker-sticks are operated at the same time and are moved toward each other-that is, the right-hand picker-stick is moved from right to left and the left-hand picker-stick from left to right. As the fly-shuttle is at the right-hand end of the shuttle-race, it is thrown by the right-hand picker-stick from right to left, making plain weaving. Before the fly-shuttle arrives at the left-hand end of the shuttle-race the left-hand picker-stick has been moved back in the direction from right to left, and is thus out of the way and permits the fiy-shuttle to remain at rest at the left-hand end of the shuttle-race. At the same time the right-hand picker-stick has been moved from left to right and is in a position of rest. The swivel-shuttles are now lowered and are moved from left to right and weave part of the figure and are then raised. Then the left-hand picker-stick is moved from left to right and throws the fly-shuttle through the race from left to right, making plain weaving, the right-hand pickerstick remaining in a position of rest. The swivel-shuttles are now again lowered and moved from right to left and weave part of the figure 'and are then again raised. Then both picker-sticks are moved toward each other again, as stated above,and the described operation is repeated, and so 011 until the loom is adjusted for plain weaving, when the picker-sticks throw the fiy-shuttle alternately in opposite directions and the swivel-shuttles are out of action.

The loom is supposed to be in motion and performing plain weaving with the devices in the position shown in Fig.4, at which time the fly'shuttle 0, under the combined action of rollers j j, leversF F, picking-sticksj 'j and springs j, throws into the fabric the full number of picks or wefts, the swivel-shuttles O being at rest. As the plain weaving proceeds and a figure is to be woven into the fabric by the swivel-shuttles C according to the pattern, the jacquard or other pattern mechanism pulls up the cord 13, which action draws the shaft B through its bearings in the direction toward the pawl E until the pawl enters the notch E and holds the shaft B in position to the right-hand side of the loom, as seen in Fig. 6. The moving of the shaft B by the cord 13, as stated, distends spring B and puts the same in tension and causes the arm B to carry the shaft B in the same direction with the shaft B, which action of the arm upon the shaft B puts treadles D and B into engagement with cams D and C and puts levers F F into engagement with rollers 43 t" on the wheel S and an arm of the crank-shaft, respectively. This change of rollers from jj to 11 t" for action upon levers F F restricts the action of the fly-shuttleo to every other pick, as the roller 4, is arranged on cogwheel S, which performs one revolution to every four revolutions of the cog-wheel S, while the roller 2" is arranged .on the camshaft K, that performs two revolutions to every one revolution of the cog-wheel S; hence the skip of the fly-shuttle 0 at every other pick. The treadles D and B having been put into engagement with cams D C by the moving of the shaft B by the arm B, as stated, the treadle B by means of cord B depresses the inner end of bar B which action puts in tension spring 0 and by means of the lever B brace 0 and link B moves the swivel-rack O and swivel-shuttles O to the left hand across the loom, as seen in Fig. 2, to form the figure in the fabric. The cam D by means of the treadle D depresses the bar D whereby by means of rods D D the required downward movement is given to the swivel-rack C and the springs D D are compressed. The fly-shuttle 0 has thus been restricted to every other pick and the swivelshuttles O thrown across the loom to the left hand in the manner stated to form the figure in the fabric. The spring 0 raises the inner end of the bar 13", when the treadle isreleased by the cam, which action of the spring upon the bar, through the lever B brace 0 and link 13*, throws the swivel-rack C and shuttles C to the right hand across the loom, as seen in Fig. 2, to form the figure in the fabric. The springs D D then raise rack C to remove the same out of the way of the flv-shuttlethat is, when the lever D escapes the action of cam D The figure having been woven in the fabric by the swivel-shuttles and the weaving in the loom changed from plain weaving to plain and swivel weaving combined, the cord E is actuated by the jacquard or other pattern mechanism, which elevates cord E at the proper time and lifts the pawl E from the notch E, when the spring B draws shaft B in the opposite direction from the action caused by cord B which reverses the action of the devices, removes the restriction from the fly-shuttle 0, and puts the swivel-shuttles at rest, the same now being in the raised position.

The collar E on the shaftB (shown in the modified construction in Fig. 9) for the action of the pawl may be used instead of the notch E and the location of the shaft B changed to any other suitable position in the loom without changing the nature of my invention. Hence I do not confine myself to the precise construction or location of the shaft shown.
