Y Be it known that I, BE GT M. W. HANSON, a citizen of Sweden, who have declared n1 intention of becoming a citizen of the United States, residin atHartford, in the county of. Hartford and ftatjeof, Connecticut, have in-f vented certain I ew and useful Improvements 'in'Compensating Bearings for Maehine-S pindies,- of which the following is a specification.
This invention relates to means for auto- Inatically alining niachine-spirulles, and more particularly those carrying tools of grinding and milling machines, in which correct positionof the spindle must always be main- 1 5 tained in order that accurate Work may be produced;
Ainong he severalobjects of theinvention hereinafterset forth one of importance is the provision of improved means for so supporting the spindle that it will automatically be brought to a true position should irregularities inthe running thereof exist.
A further ob j ect of the invention is the provision of DIOMISTOI securing the supports for rrect alineinent of the In the accompanying drawings, Figure 1 is an end vievv of-the tool slide of a grinding -mac hine to which the invention is applied Fig; 2 is a plan View of the tool-slide of a. grinding-n1achine,with the invention shown in place thereon. Fig. 3 is a horizontal sec.- tion takenon line 3 30f Fig. 1 looking in the direction of the arrow. Fig. 4is a longitudi- 3 5 nal vertical section on line-4 4 of Fig. Fig. e ofthe bearing brackets 5 is a side'view of on chine, andFig. 6 anend a tubular bearing 14,
is formed, "with perforated vertical boss 16 rising base-plate at the opposite longitu(finally-perforated' b top. Depending from th these bearing-bl from oss 17 along i-ts e has ocks aretubular studs 18, which are received in of the orossslide.' (See Fig. through each bearing ld is a swivel-bolt 20, having a reduced and externally-threaded extension'.20, which engages threaded seat 21 in the end of a bearing 22', said bearing being provided with a rabbeted journal 22, ditting'into the chamber 14 aforesaid. As a pairofthese bearings isillustrated and as each is alike, both are de same numerals; i In each bearing 22 groove 22*,fed'fro1n the fitted in each bearing is a tapered bore-said sleeve being threaded at 24 at one end and rabbeted at 24? at its opposite. extremity. A dust-cap 2" .receive the shaft 4, is fitted on the rabbeted end of the sleeve 24, a engages the thread 11 1, said nut being {-ternally threaded at 26.
this nut is aeap 27, intern betweenthe c or blocks of the ma View of said bearing-bracket.
' Like numerals designate similar throughout the several views. I
Referringto the drawings, thenunleral 1 designates the-slide of a grinding or analo' gous machine, said slide being mounted on Ways? ofthe bed 3.
Designated by 4 is'the spindle of the machine, said spindle carrying a belt-pulley 5 and having a conical bearing 4 and a'reduced 27", and-fitted and threaded extension 4 To the end of 26 and tl'ie'inner wall of spindle 4 is secured a hub 6, having a flange l. flange 28 of an internally reversely tapered 5o 6 on itsinner side, against whic'hislittedthe split box 28,-as illustratedin Fig. 3 reducing-tool employerL-ior instance, the or lost motion may bereadily taken grinding-disk 7.

diameter than the bore in which it is fitted,
and consequently a slight rocking movement of each bearing 22' is permitted in the blocks" 12 and 13 to enable the shaft 4 to center itself in a vertical plane. lar boss 16 of each standard a bolt 35 is passed and is threaded at its inner end into a part of the slidel, and through the diagonallyopp'osite corner of each block 12 and '13 a bolt 36 is passed and is threaded into the bed, said bolts being of less diameter than the bores in which they are fittedwto thus enable the blocks tohave a slight horizontal movement around the swivel-bolts 29 29.
At its outer end each swivel-bolt is. shouldered at 20 and above the shoulder is.
provided with' a hexa onal head 20*, by
which it may be manipu ated. I 4
When the spindle 4 is started in'rotation, all the bolts just described are loose, and an opportunity is therefore given for the spind e to center itself in correct running position. After this result has been accom-y plishedthe bolts are screwed home and all of the parts are locked firmly in place, so 1 that there can be no movement of any of them. Should wear of the s indle take place, this is readily corrected yactuating 5, the split sleeve 28 by means of the nut'26 and- ,ca 27.; This cap 27- also, likethe cap 25, serves as a dust-guard to prevent the entrance of foreign matter to the bearing, while the chambered hub 6 serves a similar purposein -surroundin the end of the ca 25.
