Description

UNITED STATES PATENT OFFICE.
JOSEPH XV. COLLINS, OF PAWTUCKET, RHODE ISLAND.
SPlNDLEfBEARING.
SPECIFICATION forming part of Letters Patent No. 629,954, dated August 1, 1899.
Applications@ March 1v, 1899.
To all who/'1t t may conce/1n:
Beit known that I, JOSEPH W. COLLINS, of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and usefullm provements in Spindle- 4 Bearings; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyin g drawings, and to the letters of reference marked thereon, which form a part of vthis specification'.
This invention relates to the spindles and their holders that are used in spinning and twisting machines.
Figure l represents the spindle and its holder in elevation. Fig. 2 is a vertical section taken on line 2 2 in Fig. 3, showing the bolster, the case that holds it and other parts in section, except the spindle, which is in elevation. Fig. 3 is a top view of the case and bolster. Fig. 4: is a vertical section of the bolster separate on line 2 2, Fig. 3. Fig. 5 is a top view of the bolster with part of a spindle. Fig. 6 shows a vertical section of the case that holds the bolster separate on line 2 2, Fig. 3. Fig. 7 is a top view of the case.
The object of this invention is to Vproduce a steady-running spindle capable of'being driven at a high speed by making the bolster in which it turns free to turn automatically in the case in which it is held and in this Way to present diderent sides of the bolster to receive the strain' of the band that .drives thel spindle. This distributes the Wear on all sides of the bearing of the spindle in the bol'- ster and prevents the Wearing on one side alone, which causes the spindle to run out of true and make a reduction of speed necessary. It also provides means for oiling both the bolster in the case and the spindle inthe bolster.
It consists of an outer case A, which is held in a spindle-rail (not shown) by means of the two screw-nuts b b in the usual way. Y This case A has a chamberC made in its center for nearly its whole length from its top. The chamber C has straight sides and tapers down smaller to the bottom, and a bolster D is made tapering to just t into the tapering chamber C and turn easily in it when oiled Serial No. 709,430. @l0 mdli) .through the oil-supply tube h, that enters .is litted to run in the usual manner, and a narrow groove J is made on one side of the bolster its whole length, and an annular groove j is made around Ythe bolster opposite the supply-tube h. Small holes e e are made through the bolster D in the groove J into' the upper and lower parts of the spindlebearing, and the purpose of both the groove J and the holes e is to facilitate the circulation of the oil all around the bolster in the case and around the spindle in the bolster.
I In operation when the tube h is filled With oil it will work its Way by the gro'ove j around the bolster and through the vertical groove J and holes e e into the bea-ring of the spindle B, and the thin film of oil between the bolster D and case A will hold the former free Vto turn in the case; but as the diameter of the Yspindle-bearing is smaller than the diameter of the bolster the friction on the spindle will be less and the bolster will not run with the spindle, but will only be turned slowly by it,
-just sufficient to present all sides of the socket 'Letters Patent-,-
- In a spindle-bearing for textile purposes, 1the combination of a case with means for securing it to a spindle-rail, a tapering chamber made in said case, a'bolster also made tapering to t closely in said chamber throughout its length and having an annular groove made around it, and a vertical groove made in one side of the bolster with holes in said vertical groove passing through to the inside of the bolster, and a socket made in said bol-Y ster for a spindle, substantially as described.
In testimony whereof I have hereunto set my hand this'llth day of March, A. D. 1899.
, JOSEPH YV. COLLINS. In presence of- 4 BENJ. ARNOLD, HOWARD E. BAnLow.
