IMPROVEMENT IN SPlNDLES FQR SPI'NNING-MAHINESa Specification forming part of Letters Patent No. 172498, dated January 18, 1876; application filed i Match 15, 1875. i

To all whom it may concern:

Be it known that I, DAVID HALL RICE, of Lowell, in the county of MiddleseX and Commonwealth of Massachnsetts, have invented certain Improvements in Spindles for Spinning-Machines, of which the following is a specification Thiis` invention relates to that class of spindles commonly known as dead and live spindles; and consists, first, in the connection of a fountain-reservoir with the upper hearing of the live-spindle by means of a passage-way made through the dead-spindle from a point below outside lower hearing; and, its object is to insure the constant lubrication of the upper spindle-bearing, (independently of the supply of oil contained, or which passes np between the surfaces of the dead and live spindles, when the latter is in rotation,) whereby the oil reaches the upper spindle-bearin g 0011- tinnously in a natural and limpid state, as hereinafter described.

In the drawings, Figure l represents an elevation of a spindle andbolster with my improvements. Fig. 2 represents a vertical section of Fig. 1. Fig. 3 is a horizontal section of my dead-spind1e, showing the oil-passages.

A is the rail of the spinning-frame. B is the live-spindle. (l is the bolster and oil-cup for the lower spindIe-bearing. This bolster is attached to the rail of the frame by a nut, in the usual way. lnto this bolster is inserted the dead-spindle, which is formed of two parts: a tube or shell, b, and an internal post or standard, 0, which is slipped into and made to fit closely to the internal bore of the tube b. In the top of the post c is forned the upper bearing a: of the live-spindle. On one side a vertical groove, n, is cut in the post c, before it is slipped within the tube, the groove n eX- tending the entire length of the post. This groove is thus made to form a passage for the flow of oil when the tube and post are slipped or crowded together. The advantages of thu's forming this passage are, that it is cheaply and easily done, and the combination of the post and tube forms it substantially through a solid steel dead spindle ot' great rigidity, while if the tube Were used alone it would not be stiff enough to carry the live-spindle steadly without increasing its size and bearings to render its application to spindles impracti-, At the lower end of the upper spindle-` cable. bearing a; a passage, z, is made through the post c, connecting the groove n with the bearing. The tube b is made to extend' a little higher than the post c, so as to form-a small oil-cup at its upper end. At the lower end ot' the tube b it is capped with a cover, m, fixed securely to it, and serving to support the post c, which rests the cover m vertically in position withinthetube. Through the center of. the cover m a small hole is bored, and a tube, '0, has one end screwed into this hole, and is bent around andicarried vertically upward behind the rail of the franie, and sustains upon its upper end a fountainreservoir, u, at the same height as the upper end of the dead-spindle. The top of the reservoir u extends upward, however, somewhat higher than the dead-spindlc.

It is n'anifest that, the reservoir u being supplied with oil, the upper hearing x of the spindle will be kept lubricated by means of the tube '17, groove a, and passage z, without the oil being exposed to the action of the rotation of the internal surface of the live-spindle around the external surface of the dead-spindle, which tends to consolidate the oil and clog the passage ot' it to the upper hearing. Besides, the action ot' the oil while being lit'ted by the rotation of the live-spindle causes frietion between the contiguous surfaces ot' the live and dead spindles, and requires more power to drive the spindle, all ot' which is avoided by my present improvement.

The fountain-reservoir u may be provided with a cover to exclude dirt, it' desired. The lower spindle-bearing is upon the tube bat the bottom end of the live-spindle, and when the post 0 is fitted to the internal bore of the tube b it is made with what is known as a running fit--that is, so as to be readily slipped in and out of the tube Without having any lateral play. It may be itted more or less tightly, but I prefer to fit it as above described.

The efi'ect of this Construction is that the vibration imparted to the tube b by the lower dead-spindle will overflow the Iatter and run down between the dead and live spindles into the oil-cup U, where it will lubricate the lower' hearing. The tube 'u is made to screw into the cover or cap m, so as to be attached to the latter after the bolster is inserted into the rail of the spinning-frame, as it would be difficult, and in some cases inpossible, to insert the bolster into 'the rail with the tube a) and its fountain attached to the bolster. This detachable joint also enables the spindle to be taken apart and readily cleaned, ii' any of its oil-'passages become clogged. The vertical portion of the tube 'u and its fountain-reservoir u are carried far enough away from the liveispindle vertically upward to allow the ring or traverse rail E of the frame to pass up and down around the bobbin and spindle alongs'ide the fountain and tube v, and in front of them, and the fountain and tube a re behind the rails of the frame, out of the path of the traverse, and do not interfere with the operations of spinning and doflng, while accessible to the spinner' to oil the spindle, which is of A great'advantage.

What I claim as new and my invention is- 1. The combination of the fountain-reservoir u and its tubula-r extension v, with the upper ,spindle-bearing x, and the passage n formed within the dead-spindle from a point below the lower spindlebearin g, substantially as described,

2. The combination of the fountain-reservoir u and its tubular extension u, extending higher than the top of the dead-spindle, with the lower spindle-bearing and the passage n, and hollow live-spindle B, substantially as described.

3. The combination of the tbuntain-reservoir u and its tubular 'extension v, with the pas'- sage n, the two having a detachable joint, substantially asdescribed.

4. The combination of the fountain-reservoir u, placed behind out of'the way of, and along- -side the path of, the traverse or ring rail, and

its tubular extension o, with the spindle, sub-' stantially as described. p 5. The oil-passage n, formed within the deadspindle from below the lower spindl'e-bearing to its upper end, substantially asdescribed.- DAVID HALL RIGE. Witnesses: p
