vSPINDLE-BEARIN.C-ADtlUSTING DEVICE.
SPECIFICATION forming part of Letters Patent No. 537,275, dated April 9, 1895,
Application filed January 3, 1895.
To all wiz/ml it may concern:
Be it known that I, WALTER A. CHANDLER, of Fall River, county of Bristol, State of Mas.- sachusetts, have invented an Improvement in Spindle-Bearing-Adjusting Devices, of which Y cv struction that the parts are simplified and so combined that the lateral bearing may be adjusted vertically with relation to the spindle while the latter. is running.
. In accordance withv my invention the lateral bearing is attached to a support mounted exteriorly on the supporting case, and shown as screwed upon the top of the case above the rail, rotation of the support upon the case raising or lowering the bearing and also preaccidental movement of the support I have .provided a locking device to positively engage therewith under normal conditions.
Figure l in vertical section and partial elet vation represents a spindle bearing embodying my invention. Fig. 2 is a transverse section thereof on the line or--sa Fig. 3 is a similar section on the line 0c m. Fig. 4 is an under side view of the support detached; and 4o Fig. 5 is a side elevation thereof.
Referring to the drawings, the spindle rail A-and spindle B having a sleeve whirl B are and may be of usual construction, the spindle being prevented from rising by means of a hook C, connected with the supportingcase D containing the bolster bearing a and the step b. I have herein shown the spindle step b as a pin held in the bottom of the case D, and loosely entering the lower end of the 5o bolster bearing a,thereby serving to center its inner end. The upper end of the supporting To prevent Serial No. 533,704. (No model.)
case is shown as provided vwith an annular recess or groove d, formingan oil reservoir,
`connected with the interior by suitable ducts d', the central hub or boss d2 being externally screw threaded to receive thereon the bolster `bearing support, shown as a tube e, provided with an annular notched flange e and interiorly threaded at its lower end at e2, to engage the threaded boss d2 on the supporting case. The barrel of the support c is attached to the bolster bearing a in any suitable manner, shown as a pin 5 extended through the support into the bearing, which latter is internally tapered to receive therein the taperblade ofthe spindle B. By rotating the support in one or the other direction upon the supporting case D it will be, by means of the screw thread connection, raised or lowered, to elfect thereby a relative vertical change of position between the bolster bearing and the step b. The extended barrelof the tubular support e extends beyond the top of the lateral bearing a and practically forms a solid extension of the supporting case D, between the bearing and the sleeve Whirl B. Oil holes a are made in the wall of the lateral bearing a.
In order to absolutely prevent any accidental rotation of thev support c and consequent change of adjustment of the lateral bearing a I have provided a positive locking device, herein shown as aspring finger a2 held in the top of the case to normally enter one of the notches cX in the Hangs e' of the sup` port.
When the bearing is' to be adjusted the spring finger is Withdrawn from the notch and the supporte turned until the desired adjustment' is effected, the linger springing back into the adjacent notch.
It will be seen that the flange e of the bearing support is at all times readily accessible, and that when it is desired to raise or lower the bolster bearing it is only necessary 95 to unlock and rotate the support, Without at all interfering with the running ot' the machine at speed. d
The bolster bearing may be readily removed with the support therefor by unscrew-I roo ing the latter from the supporting case.
I claiml. The combination with a supporting case adapted to be fixed in a spindle rail, aspindle step therein, and an internally tapered bolster bearing, of a vertically adjustable support for the bolster bearing, mounted exteriorly on the case above the rail, to effect by its adjustment a relative vertical change of position between the bolster bearing and the step, substantially as described.
2. A supporting case adapted to be fixed in a spindle rail, a spindle step therein, and a tubular extension vertically adjustable on said case above the rail, combined with an internally tapered lateral bearing Within the case and 'tubular extension, attached to and movable with said extension, movement of said extension varying the relative vertical position of the bearingand step, substantially as described.
3. A supporting case threaded at its upper end and adapted to be fixed in a spindle rail, a fixed spindle step, and a tubular extension adjustably mounted on the threaded end of the case, combined with an internally tapered hollow lateral bearing within the case and extension, attached to, and movable with said extension, and a tapered-bladed spindle in said bearing and resting on the step, rotation of the extension on the case effecting the vertical adjustment of the bearing relative tothe spindle, substantially as described.
4. A supporting case containing a spindle step and adapted to be fixed in a spindle rail, a tubular support screwed upon the upper end of the casing, and an internally tapered bolster bearing within the case and support and movable with the latter, combined with a taper bladed spindle to enter the bearing and rest on the step, rotation of the support; vertically adjusting the bearing, and a lock to engage and normally prevent rotation of saidv support, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WALTER A. CHAN DLER.
