`DAVID HALL RICE, OF LOWELL, MASSACHUSETTS.
IMPROVEMENT IN SllNDLES FOR SPINNING-MACHINES.
Specification forming part of Letters Patent N o. 134,771, dated January 14, 1873.
To all whom it may concern:
Be it known that I, DAVID HALL RIcE, of Lowell, county of Middlesex and State of Massachusetts, have invented certain Improvements in Spindles of Spinning-Frames, of which the following is a specification:
My invention consists of the combination of a dead-spindle having a spiral thread around it with a live-spindle closed at the top over the dead-spindle, as hereinafter described, and revolving upon and around the latte).1 and the spiral, said spiral being so proportioned or regulated that the pressure of oil created by it at the top of the deadspindle shall Vserve to sustain the live-spindle without lifting it oif its bearings on the dead-spindle; the object of the invention being to prevent friction or wear of the bearings of the live-spindle by its vertical pressure upon them, and to cause the live-spindle to run more easily and' steadily.
Figure 1 is a vertical sect-ion of a spindle containing my improvement; Fig. 2 is -the dead-spindle, detached from the other parts 5 Fig. 3 is the dead-spindle and oil reservoir, with the live-spindle removed.
D is the rail ofthe spinning-frame. A is the live-spindle, having a chamber closed at the top extending about half way upward from its lower end, for the reception of the dead-spindle B, about which it revolves. The livespindle is provided with a whirl, e, and projects downward into the oil-reservoir C.V At the bottom end of the live-spindle it is provided with a bushing of less internal diameter than the chamber in the spindle above it, on which bushing it turns upon the dead-spindle B, and which serves to prevent the live and dead spindles from touching between itself and the upper bearing n. VThe weight of the live-spindle rests at the top of the dead-spindle B. Just above the lower bushing of the livespindle the dead-spindle is cut away so as to leave the'spiral left-hand thread or ridge c around the spindle B toward its top end. The spiral c is carried part of the way to the top of the dead-spindle, and the latter is then left smooth the remainder of its length above the spiral.
Care should be exercised to proportion the length of the spiral c and of the smooth part of the dead-spindle above it, so that the pressure of oil produced by the rotation of the livespindle shall not be great enough to lift the latter off the dead-spindle, as is the case when the spiral extends too far up the dead-spindle.
The parts being properly adjusted to each other the rotation of the live-spindle brings the oil up through the lower bushing, and as it is carried around between the live and dead spindles it cornes in contact with the spiral c, and is pressed upward into the upper part of the live spindle and serves to "sustain its weight, and it revolves on the column of oil at the top of the dead-spindle.
It is evident that the live-spindle must revolve much easier in this way and with less wear to its upper bearing than when its entire weight is supported by the dead-spindle directly. As incident to the function of the spiral already described it serves also to surround the upper bearing with a pressure of oil.
What I claim as new and my invention is- The dead-spindle B, provided with the spiral c, in combination with the livespindle A, having its chamber for the dead-spindle closed at the upper end over the latter, substantially as described.
DAVID HALL RICE.
