MACHINE FOR SETTING COP-TUBES ON MULE-SPINDL/ES, 86C.

SPECIFICATION forming part of Letters Patent No. 245,339, dated August 9, 1881.

Application filed February 3, 1851.

To all whom t may concern:

Be it known that I, JOSEPH A. BARBER, a citizen 0f the United States, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Machines for Setting' Cop-iv Tubes on Mule-Spin'dles and upon the spindles of other similar machines, of which the following is a specification.

This invention relates to the details ot' construction of a machine for grasping simultaneously a series of cop-tubes near their bases, and for drawing said tubes completely onto their spindles, the object being to enable an operative to rapidly and regularly set cop-tubes upon the spindles, setting the whole series at a uniform height by one movementof the machine, therebysavingmuch time over the usual method of setting` one tube at atime separately.

In the drawings forming a part ot' this specification, Figure lis a plan view with the pressure-plate of the machine removed and with the cop-tube clamps standing open. Fig. 2 is a rear elevation of the machine, partly in section and Fig. 3 represents a series of spindles, looking from the machine toward the back side of the spindles, and a front elevation of the machine, showing the tube-clamps closed upon the tubes and in the position in which the invention will be found after the machine has drawn thetubes onto the spindles ready to be disengaged from them.

In the drawings, A is the frame. B is the pressure-plate. ce are spring-sockets pending fromthe under side of the pressure-plate B. e e are triangular slide-blocks, pending also from the under surface of said pressure-plate. fi i are spiral springs in tube-sockets c c. 0 o', are two horizontal slide-bars. s s are slide-bar guide-posts. t e are tube-clamps pivoted on frame A, the straight ends of which enter openings a: in the slide-bars o and o. 2 2 are spiral springs, one end of which is attached to an arm, 3 8, projecting from the slide-bars o o', and the other ends of said springs are attached to the bottom of frame A. Two arms, 4 4, project horizontally from said slide-bars under the diagonal face ofthe blocks e e on the under side of pressure-plate B. The slide-bar guide-posts s s are secured to the base of frame A, and two other posts, 5 5, stand likewise upon (No model.)

said frame under the lower ends of the springsockets c c, beneath the spiral springs therein.

Two other posts, G G, are xed on frame A,

which serve to guide the vertical motion of the pressure-plate B, whose ends are pierced to pass over said posts. Screw-supports 7 are fixed upon each end of frame A, into which two adjusting-screws, S, are placed, as shown. 9 are spindles. l0 are cop-tubes. l l is a spin- (lle-rail.

The slide-bars o o" are fitted to slide horizontally in opposite directions in the slide-bar guide-posts s sv on frame A, actuated by the contact of the slide-blocks e e with the arms 4 4, when the pressure-plate is moved backward; and springs 2 2 serve to draw the bars 0 0 back to their starting-points, wheny the action of the pressure-plate ceases by its being allowed to rise. The spiral springs in the spring-sockets c o lift the pressure-plate away from the frame A, when said plate is left free to rise. The said slide-bars 0 0 are arranged on different horizontal lines in the rear of the tube-clamps, because the top half of those clamps is higher than the lower half, the arm of the top half entering the upper bar, and that of the lower half entering the lower bar; consequently, when the said slide-bars are. moved, as they are, in opposite directions by the downward movement of the pressure-plate B, they cause the clamps to be closed; and when the pressure-plate rises, the clamps open by the reverse action of the clamp-bars, caused by the said springs 2 2.

rlhe operation of my machine in setting coptubes is as follows: An operator passes along in front ofthe spindles on the machine, passing the lower end of the cop-tubes just over the top end of the spindles. That operator is followed by another one, carrying this machine, which may be arranged with a sufficient number of clamps to operate upon any convenient number of spindles, the clamps being in the position shown in Fig. l, and places it in a position to bring the lower portion of the tubes which have been placed upon the spindles within the clamp-jaws, when he forces down the pressure-plate B, causing said clampjaws to shut up upon the tubes. The operator then brings the machine down toward the spindle-rail 11, carrying the tubes, with the ina- IOO chine, down to the position seen in Fig. 3, when he lets the pressure-plate B rise up, causing the clamps to be opened, and moves the machine along, and in like manner grasping another series of tubes and sliding them all downsimultaneouslyontothe spindles. When the machine is moved down to draw the tubes onto the spindles, the adjusting-screws S, set in each end of the machine, strike the rail 1l and determine the height to which the tubes are drawn upon the spindles.

By the use of this machine, as just described, very much time is saved in setting cop-tubes upon mule-spindles, for by the ordinary method an operative draws one tube at a time upon the spindle, regardless of any precise method for determining a uniform height for all the tubes, and consequently the winding of the yarn thereupon is not uniform relative to their ends, as it should be; but by using this machine a series of ten or fifteen tubes can be set simultaneously as quickly as an operative can set one tube. They are all placed uniformly upon the spindles, as seen in Fig. 3, and the inconveniences resulting from setting tubes singly are all obviated.

It is obvious that this machine may be constructed with one side of the clamp-jaws fixed and the other side movable by like devices to those shown inthe drawings; butto obtain ease and uniform action in the slide-bars and press ure-plate it is preferable to construct the machine as herein shown.

That I claim as my invention is?A Ll. In a machine for setting cop-tubes onto spindles, the combination, with a series of pivoted tube-clam ps, fv, ofthe perforated slide-bars o o', having the arms 4 4 thereon, the springs 2 2, and the pressure-plate B, having the triangular blocks e thereon, and of appliances, substantially as described, for lifting said pressure-plate, substantially as fet forth.

2. The combination, with the series of pivoted tube-clamps o and case A, and with appliances, substantially as described, for closing and opening said clamps, of the adjustingscrews S in each end of said frame, substantiall y as and for the purpose set forth.
