SPINDLE-BEARING.

SPECIFICATION forming part of Ietters Patent No. 538,995, dated May '7, `1895.

Application filed July 30, 1894.

.To @ZZ whom it may concern.-

Be it known that I, AURIN VOOD, of Worcester, county of Worcester, State of Massachusetts, have invented an Improvement in 5 Spindle-Bearings, of which the following description, in connection with the accompanying drawings, isaspeciiication,likeletters and numerals on the drawings representing like parts. j

This invention has for its object to improve spindle bearings as to'the means for preserving the proper tit between the' tapered exterior of the pintle of the spindle and the tapered interior of the lateral bearing. To effeet this adjustment the construction of the parts must be such as to enable the distance between the step and that part of the lateralV bearing which surrounds the pintle just above the step to be changed or made more or less, or, in other words, the lateral bearing and step must be separable and be .capable of having their positions changed relatively one to the other. This can be done by either raising or lowering the lateral bearing, or the step.

In myinvention the adjusting device is located in and accessible from outside the oil` ing leg.

Figure l, in vertical section, shows a spindle in a bearing containing my invention in one practical form; Fig. 2, a top or plan view of the parts shown in Fig. 1, the section of Fig. 1 being in the line Fig. 2. Fig. 3 is a section below the line Fig. 1. Fig. 4c is a' vertical section showing a modification of my invention; Fig. 5, a section in the line x3, Fig. 4; Fig. 6, an outside View of the bolster. Fig. 7 shows vthe lateral bearing in longitudinal section, and Fig. 8 a section in the line Fig.

The rail A, on which is the supporting case B, is secured by nut C, and the sleeve Whirl spindle D having a tapered pintle, are all as usual. The supporting case hasan inclined oiling leg or branch b, through which is passed the oil to oil the spindle and its hearings composed of a lateral bearing @tapered internally, and a step d. I have provided the bearing c externally with a suitable notchior shoulder c', and I have inserted in the hollow 5o leg or branch an adjusting device e, shown as Serial No. 519,022. (No model.)

" a hollow shaft having a shoulder at 2 to rest against a shoulder of the branch, the inner end of said adjusting device having an ec-l centric projection e to enter the notch c of the bearing c, so that the partial ,rotation of said adjusting device by a screw-driver or other proper tool engaging the notch e2 thereof, enables the position of the bearing c to be changed relatively to the step to provide for the proper it between the exterior of the pin- 6c tle and the interior of the bearing, a suitable set screwfserving to hold the adjusting device in adjusted position.

In my invention it will be seen that the adjustment provided for may be effected readily While the spindle is running as Well as while at rest, and Without the loss of oil.

In the modification of my invention Figs.

4 to 8, I have provided for moving the step 'rather than the lateral bearing, one being the 7e equivalent of the other in result, and therefore an equivalent. Referring to said modiication, the lateral bearing g is prolonged, and its lower end is so fixed with relation to the outside supporting case that it cannot rise therein when eecting the relative adjustment of the parts to secure the proper tit between the externally tapered pintle and the tapered interior of the said bearing, the connection being shown as effected by a screw- 8o thread at g2. The bearing g is grooved externally for part of its length to receive the shank h of the step h', the latter being extended into the bearing and across the pintle chamber in a slot h2. The shank his notched at h3 to be engaged by a suitable projection h4 on the adjusting device h5, placed in the oiling leg or branch vm, the rotation of said adjusting device with its projection or projections h4 in engagement with the projectionsV 9o h3 moving the step to the extent desired to make the proper lit between the pintle and lateral bearing.

' In my invention the adjusting device for changing the relative positions of the lateral bearing and step to insure the proper fit or looseness between the tapered pintle and step,

is located above the top of the spindle-rail and it is shown as accessible through the oiling leg, and While I have shown two forms of roo bined with adjusting mechanism for said bearing and step, located in said leg orbranch, in positive engagement With one of said members to move it relatively to the other, whereby the relative position of the said lateral bearing and step may be positively changed when desired, for the purposes set forth.

2. The supporting case having an oiling leg or branch, and a lateral bearing and step located in said supportingr case, combined with an adjusting; device located in said leg: or branch, said adjusting device having through it an oil passage and provided at its inner end with a projection, whereby by the rotation ot' said adj Listing` device the relative positions of the bearing and step may be changed in the supporting case, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

AUBIN WOGD.
