PATENT OEEICE.
GEORGE W. BRIGGS, OF FISKEVILLE, RHODE IsLAND.
IMPROVEMENT IN SELF-LUBRICATING SPINDLE-BEARINGS SPINNING, dic.
Specification forming part of Letters Patent No. 47,228, dated April 18, 1865.
To all whom it may concern:
Be it known that I, GEORGE W. BRIGGs, of Fiskeville, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Vertical and Inclined Bearings; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specilication, in which- Figure 1 is an elevation of a cotton-spinnin grame spindle to which my invention has been applied. Fig. 2 is an elevation of a longitudinal section of my improved bearing and its cup detached from the spindle. Fig. 3 is an elevation of a longitudinal section of a modification of the bearing. Fig-4 is a erosssection of the spindle A and cup l), taken on the line x' ot Fig. 1.
Similar letters of reference indicate like parts.
This invention consists in setting the lower part of vertical or inclined bearings in a cup or socket which will receive and retain the lubricating material which escapes from the boarin g, and, in combination therewith, forming a spiral groove around the interior of the bearing fromits bottom to the said chamber.
For the purpose of illustrating my invention, I have selected a cotton spinningframe spindle, to which I have here shown it applied, but it applies equally well to all upright bearings and to such as are more or less inclined.
A is a spindle fitted with a sheave, B, by which it is rotated in the usual Way. G represents the bearing of the spindle, which is placed on it at a point below the plate which supports the bobbin and above the sheave B, and is to be secured in the ordinary or in any suitable way to the rail of the frame. The upper part of the bearing is enlarged, (see Figs. l and 2,) for the purpose of forming a chamber, E, at that point. This chamber is inclosed above by the annular top J of the bearing, which approaches very nearly to the sides of the spindle, a narrow slot, I, being out in the to'p J and extending nearly to the wall of the chamber E, to receive the nozzle of the oil-cup or lubricator when the bearing is to be supplied with oil. The lower part of the exterior of the bearin g C is turned down,
as shown at K, to a thin shell, forming a shoulder, L, around its exterior. 4The thin part K of the bearing is received within the top of a cylindrical cup, D, which is formed or fitted around the spindle above the sheave B, the said sheave, if the cup is set directly upon it, y l
.serving as the bottom of the cup. `The bear- Ing' is iitted so as to pass into the cup about as far as is shown in the Figs. 2 and 3, the
shoulder L being separated by a narrow space 3 from the top of the cup. The inner diameter of the said cup D is made greater than the diameter of the spindle, so as to form an aunular space or reservoir, H, within it, extending to the bottom of the cup or to the upper surface of the sheave, and a chamber, F,`is
formed within the cup near its top, as shown f in Fi gsI 2 and 3. A spiral groove, Gr, is formed on theinside of the bearing, beginning near l y its bottom and running upinto the chamber E.
shows a longitudinal section of the I Fig. 3 bearing and the cup or socket in whichits lower end is tted, the saidbearing being modified from the example shown in Fig. `2 in having a chamber, E, formed in it near itstop without enlargingits diameter, the said chamber in this illustration consisting of two compartments, l 2, one above the other.`
The o eration of m im iroved bearinfr isas l) s follows: When the bearing is lubricated, the
oil passes down through it, and the excess is` gathered in the cup D.
As the rotation of a spindle in aeommou spin nin g-frame is at the rate of about tive thou- I I sand tive hundred (5,500) revolutions a minute,
it is evident that when the common bearing l is used any excess of lubricating material will speedily be thrown oli' and escape without any further benefit to the bearing; but when myim-` proved bearing and cup are used, the excess,
being stored in the reservoir H, will be brought I up to the bearing by centrifugal force during the rotation of the spindle, a portion`thereot' escaping outside the part K of the bearing, where it is received and retained in the cham- I ber F, but the largest part will be carried up within the bea-ring along its spiral groove G to the chamber E, where it is retained.
When the rotation of the spindle ceases, the
oil gathered in the chambersE and F falls A y again to the bottom of the cup7 from whence it is again brought to the cup, lubricating the bearing at the next rotation of the spindle.
Vhen the ordinary bearings are used for spindles of the kind here shown, it is necessary to oil them two or three times a dayj but my improved bearing will run tWo Weeks with one supply or application of lubricating material, thereby saving not only lubricating material but also much time and labor, since with the bearings now commonly in use the spinningframe has to be stopped dnrin g the process of lubrication.
The oil Which is received within the bearing and cup is preserved in a pure. condition and free from lint and dirt by means of the chamber E, Whose top is brought close enough to the spindle or shaft carried in the bearing to exclude such and other foreign substances.
spiral groove G in the bearing C, for the purposes set forth.
