SPlNDLE SUPPORTING AND DRIVING DEVICE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 351,480, dated October 26, 1886.

Original application filed October 10, 1883, Serial No. 108,581. Divided and this application filed May 12, 1884. Serial No. 131,105.

To all whom it may concern..-

Be it known that I, JosEPH E. TYNAN, of Paterson, in the county of Passaic and State of New Jersey, have invented an Improvement in Spindle Supporting and Driving Devices for Spinning-Machines, of which the following is a specification.

This invention relates to the spindle-bolsters, bolster-sockets, and means for driving the spindles and supporting and lubricating the parts.

This improvement is especially adapted to doubling and twisting machines; but it may be used in spinning-machines.

Figure 1 is an elevation of two of the spools and mechanism for driving the same in a silkdou'bling machine, a portion of the frame with the'rails and belt-shifter in section, and adj acent'parts of the machine being also shown. Fig. 2 is a sectional plan at the linear a: of Fig. 1. Fig. 3 is a vertical section,in larger size,of ,the bolsters, bolster-sockets, driving-pulleys, and rail, the spindles and supporting rods being in elevation; and Fig. 4 is a sectional plan of part of the rail and the bottom of the bolster-socket, the screws being in elevation.

Reference is hereby made to my application for patent No. 108,581, filed October 10, 1883, for a more full description of those parts that are only briefly mentioned herein, the present application being a division of my said application No. 108,581.

The spools a and b, Fig. 2, contain the threads that are to be twisted and laid togather, and the spool or bobbin P receives the thread as twisted together and wound upon such spool. The spindles a b Q receive the respective spools a b P. The spindles a b will usually be slightly tapering, so that the spools will be held thereon when pressed down to place. The ring and traveler h and rail 0 are to be of any ordinary character, and will be raised and lowered to lay the thread upon the spool P by the usual mechanism.

Upon the spindle Q there is a friction-disk, c, with a pulley, T, below it, and U is a loose pulleyupon whichthe driving-belt wisshifted when the belt-shifter is moved to stop the spindle.

The spindles a b have upon them, respectively,the friction-disks a b, the edges of which are in contact with the edges of the disk 0 of the fast pulley T, and hence the spindles a 11 receive motion from this pulley T. The bolster-sockets form also oil-receptacles. The bolster-sockets 13* for the spindles a b are made with flanges 44, resting upon thebolster-rail a, and said sockets B have screw-threads at their lower ends for the clamping-nuts 45, below such rail a. The nuts 45 are tightened after the sockets have been adjusted by the screws 46.

Thebolster-sock et R, where it passes through the bolster-rail a, is made with an enlargement above-the rail to form the oil-cup r, and also to give a bearing upon the surface of the bolster-rail to retain the bolster-socket and spindle ina vertical position, and the hole through the rail is larger than'the bolster, so that the bolster-socket R and spindle Q may be drawn toward the spindles a N by the action of the belt w which passes around the fast pulley T, to insure the necessary friction between the disks a, b, and 0", but it is remarked that the means for driving the spindles are not claimed herein, but are expressly reserved forsaid application No 108,581.

'50 is a spring between the nut 51 on socket Rand the rail a to allow the parts to yield s1ightly,but to maintain the bolster and spindle in a vertical position, and 52 is a pin in the bolster-socket passing into a slot in therail a to prevent the bolster-socket revolving. tubular bolsters S are similarly made for all the spindles at 72 Q. They are adapted to receive the lower ends of the spindles, and each one has a hemispherical bearing,i ,around the central portion passing into a similarly-shaped recess at the top of the bolster-socket, and there is to be a hole, 60, Fig. 3, through said bearing '5 for oil to flow down, and apin pass ing through the upper end of the bolstersocket into the bearing, as at 39, prevents the bolster revolving. By. this construction the bolster is hung by its hemispherical bearing, and this is in line, or nearly so, with the fast and its tubular bolster may vibrate above or below the bearing 73 without varying the action of the pulleys. The edges of the friction-disks are preferably segments of globes The pulley and the friction-disk,so that the spindle enters a hole in the lower end of the screwstep I). The screw-step slides freely down over the end of the spring, so that the weight of the parts is taken upon the bearing 2". The springp tends to keep the bolster and spindle vertical; but if the bobbin is not true the spring yields and allows the bobbin and spindle to find their own axis of rotation. \Vhen the spring passes up through the bottom of the bolster, its upper end forms the step for the spindle,and by inalcingthe screw-thread upon the spring itself the aforesaid adjustment may be effected. In this latter case the spring should not pass through the lower end of the bolster-socket, because it has to be inserted with the bolster from above, and cannot be driven in tightly from below the bolster-socket; hence I bore the hole for the spring from the inside of the bolster-socket, but do not-bore it all the way through, as shown in connection with the bolster-socket B. If the lower end of the spring is squared and the hole in the bottom of the bolster-socket made of the same shape, the bolster and step will be held so thatit willnot turn, and the pin 39 may be dispensed with. There are openings (31 in the lower part of the bolster to allow the oil to pass into the spindle from the bolster-socket.

Around the spindle Q, below the fast pulley T, is the loose pulley U, that has a'hub that iits upon the outside of the bolster-socket R, and this hub revolves in the oil box or cup 1', and there is a flange, 'r", at the lower end of this loose pulley U, to prevent the cord or belt w coming into contact with the oil-cup r,aud the downward flange, r within the oil-cup, prevents oil being thrown out by centrifugal action,and the flange i- 'aids in excluding dust. There is a cylindrical dam, r within the oil cup, which prevents air-bubbles and froth that may form on the surface of the oil at the loose pulley, causing the oil to be displaced from the oil-cup, because the air-bubbles, as they accumulate and pass over the dam, are broken to a large extent by the upper edge of said dam. The disk '0 upon the standard 12 for preventing either of the spindles being lifted when a spool is pulled off, is not claimed herein, as a device of this character is shown in my Patent No. 279,674,dated June 19,1883. The drop-bar m, belt-shifter a, and frictionbrake a, and the feed-roller, stop-motion, and other devices employed with spindles, bolsters, and driving mechanism are shown in my application No. 108,581, filed October 10, 1883, and do not form any part of this application.

I claim as my invention 1. The combination, with the spindle and bolstersocket provided with a hemispherical recess at its upper end, and having a closed lower end, of a bolster having a hemispherical bearing entering said recess and resting therein, and a step for the spindle, and a vertical rod forming a spring passing into the bolster-socket and bolster, respectively, to allow a limited rocking movement of the bolster upon the hemispherical bearing, and a fric' tion-disk around the spindle and in line with the center of the bearing, and a frictional driving-disk for the same, substantially as specilied.

2. The combination, with the spindle, of a b0lster,'a bolster-socket, forming also an oilcup, a screw-step, and a spring passing into the bottom of the bolster-socket and into an opening atthe bottom of the bolster, substantially as set forth.

3. The combination, with the spindle, of a bolster having a hemispherical bearing around it and provided with a screw-step, and a bolster-socket having a hemispherical bearing, and a spring passing into the lower end of the bolster-socket and into an opening at the lower end of the bolster,substantially as set forth.

4. The combination, with a spindle, of a bolster having a hemispherical bearing, and a bolster-sockct having a hemispherical recess for said bearing, a frictioirdisk in line with the center of said bearing, and a driving-pulley below the disk, and an adjacent spindle and driving-disk upon the same and in contact with the aforesaid friction-disk, substantially as set forth.

5. The combination, with a spindle, a bolster, and bolster-socket, of a loose pullcy,thc hub of which surrounds the bolster-socket, an oil-cup, and a cylindrical dam in said oil-cup, for the purposes and substantially as set forth.

6. The combination, with two spindles, of bolster-sockets having hemispherical recesses, bolsters having bearings fitting such recesses, yielding supports at the lower end of the bolsters, means, substantially as specified, for preventing the bolsters rotating, a driving.- pulley surrounding the bolster-socket and attached to one spindle, a disk connected with the driving-pulley, and a disk upon the second spindle, with which the driving-disk comes into contact, such disks being in line, or near the centers of the hemispherical bearings, sub stantially as specified.
