SPECIFICATION forming part of Letters Patent No. 530,073, dated November 27, 1894. Application tiled September 29, 1894. Serial No. 524,480. (No model.)

To @ZZ whom it may concern.-

Beit known that I, EDWIN HITcHoN, of Accrington, in the county of Lancaster, England, have invented certain new and useful Improvements in Spindle-Supports, of which the following is a specification.

My invention relates to the supports or bolsters for spinning-machine spindles, and more particularly to that species of-such supports having an outside upright oil tube, communicating at its lower end through a horizontal branch, with the interior of the bolster. The oil tube must have a lid or cover for closing it. This cover has been sometimes aloose independent cap, and at other times a/ lid hinged to a bracket on top of the tube-the lid being in one with a projection forming a spindle holder, and constituting a counterweight for that holder. Either one of these arrangements possesses certain disadvantages which are an obstacle to their successful use. The loose cap is apt to be mislaid or left off the tube. In the case of the hinged cover, the hinge is so high, by reason of certain structural requirements, as to interfere with the requisite downward movement of the ring rail,unless the oil tube be made so short as to impair, materially, its usefulness. To remedy these and other objections, is the aim of my invention. To this end, I mount or form the cover on the upper end of an upright wire or arm, the lower part of which is bent at an angle to form an oscillating or rock-shaft mounted in a cross bearing provided in the spindle bolster base or flange, the opposite end of this shaft being bent upward to form another upright which is provided with a hook-like top part extending inwardly in position to overhang the spindle wharve and form a holder thereforthe wire orshaft before this last upward bend, being bent horizontally and doubled upon itself to form a counterweight, or counterbalance lever. All of these parts can be formed out of one and the same piece of wire, which in itself furnishes the cover and upright carrier therefor, the spindle holder and upright carrier therefor, the counterbalance lever, and the horizontal rock-shaft on which both of the carriers and the ,counterbalance leverare mounted.

In the accompanying drawings, forming part of this specification, Figure 1 is an elevation of the complete device, from the side on which the oil tube is located. Fig. 2 is an elevation from the opposite side. Fig. 3 is an elevation from the side on which the bearing of the cross-shaft is located. Fig. 4 is a plan; and Fig. 5, is a view of the combined cover and spindle holder detached.

A is the spindle; B, the bolster; C, the upright oil tube; C', the horizontal branch which puts the oil tube in communication with the interior of the bolster.

The cross bearing for the rock-shaft is shown atD. Itis readilyformedbysuitablyboringa lug or projection cast in one with the bolster base or flange. The cross-shaft is shown at a..

b is the cover for the oil tube; c, the upright carrier for said cover, united at its lower end to the cross-shaft.

e is the spindle holder.

d is the upright carrier for said holder; and f is the balance lever which furnishes the counterweight by which the shaft is rotated in a direction to cause the cover to close the oil tube and the spindle holder to overhang the spindle wharve ci. All of these partsthe cover, and its carrier, the spindle holder and its carrier, the counter-weight lever, and the rock-shaft, which carries them all-can be conveniently formed from a single piece of round rod or wire as shown in Fig. 5. The cove'r b is formed by suitably flattening and shaping one end of the wire, leaving a suitable length for the upright carrier c. The wire is then bent at an angle to form the rock shaft part a, which is of a length to extend through the cross bearing D. Beyond this point the wire is bent and doubled on itself at right angles to the rock-shaft and in about the same plane therewith for a length and in a direction to form the counterweight lever f. Beyond that point, the wire is again bent upward to form the carrier CZ, and the upper end of the carrier is then bent overin hook-form to provide the spindle-holder e. The top surface of the spindle-holder at the point where it is struck by the spindle wharve, when the spindle is being applied to its bolster, has sufficient outward bevel, as indicated at e to cause the holder to yield to the pressure of the wharve and move outwardly to allow the latter to pass, after which it will return automatically to position.

IOO

base or flange and provided with a counter-l weight arm, is not new. I am also aware that these devices have been formed in one, from a Single piece of wire. I claim none of these things, but

IVhat I do claim as new, and desire to secure by Letters Patent, is-dh The combination with the bolster, the spindie and the oil tube, ofthe rook-shaft mounted in a cross-bearing on the bolster base or flange tangential to the bolster, an upright carrier on one end of said shaft, a cover for the oiltube affixed to said carrier, a second carrier on the opposite end of said shaft, a spindle holder on the upper end of said second carrier, and a counterweight for holding the said carriers in position, under the arrangement and for joint operation, as shown and set forth.

In testimony whereof I have hereunto affixed my signature in the presence of two Witnesses.

EDWIN I'IITCIION.
