Patented Nov. 20, 1923.

UNITED .STATES PATENT OFFICE.

WILLIAM n. BAETLETT, or CLEVELAND, oHIo, As'sIGNoE 'ro `THE Ross MANEACTUE- ING COMPANY, or CLEVELAND,

OHIO, A CORPORATION OF OHIO.

HOIIIDER 'FOR WHEEL DRESSERS.

I Application iled May 7,

To all whom t may concern Be it known that I, WILLIAM D. BART- LErr a citizen of the United States, residentY of Oleveland, county. of Cuyahoga; and

State of Ohio, have invented new and useful Improvements in Holders for VWheel Dressers, of which the following lis a specification, the principle of ythe invention being herein explained, and the best mode in lo which I have contemplated applying that principle,'so as to distinguish it from other inventions.

My invention relates toholders for wheel dressers. Particularly, the invention relates c to a mounting adapted for use on the tail stock of grinding machines, whereby irrespective of the angular position of the table uponwhich the tail stock and consequently the 'wheel dresser is mounted, the dresserv may be presented squarely to the periphery of the wheel to be dressed. Furthermore., the invention relates to a vsolid mounting or holder for the dressing tool, whereby substantially all vibration of the tool during the dressing operation is obviated.

The annexed drawing and the following description set forth indetail certain means embodying my invention, the disclosed means, however, constituting but one of the 3o various mechanical forms in which the principle of the invention -may be employed.

In said annexed drawing:

Fi re l represents a plan view of a grin ing machine upon the tail stock of which is mounted a wheel dresser, supported by the new and improved holder hereinafter fully described and claimed, the traveling table upon which the tail stock is secured being ladjusted to an angle to its 4o ath of travel fora purpose hereinafter gully described.

Figure 2 represents a plan view of the wheel dresser and its holder, taken from the planes indicated by the line II-II, Figure 3;

Figure 3 represents a side elevation of the elements shown in vFigure 2 and a portion of the tail stock upon which the same are'mounted; the tail stock being assumed to be positioned parallel to the path of the traveling table; and

Figure 4A represents a fragmentary end elevation, taken from the plane indicated by the line IV-IV, Figure 2.

56 Referring to the annexed drawing, in

1921. Serial N0. 467,688.

Manufacturing Co., Cleveland, Ohio, such dresser 2 being adapted for use in dressing iiery wheels, carborundum wheels, and the 1 e. by the ordinal 3, Figure 1. When this wheel 3 is utilized for grinding work with conical surfaces, a type of which is indicated by the ordinal- 4, `Figure 1, the table 6 upon which thework 4 is mounted is angularly adjusted to the ways 5, so that the wheel 3 may travel 'over the face of the work 4 in a plane parallel to the planes of the ways 5 or to the axis of the wheel 3. However, whenever it isA` desired to dress theV wheel 3 by means of the tool 2, the tool being of a character such as shown in said Patent No. 1,256,167, and illustrated fully by Figures 2 and Bof this application, it is desirable to present the face of the tool 2 squarely to the periphery of the wheel 3 in order to dress the latter evenly. Therefore, unless the table 6 is re-adjusted into a position `parallel with the ways 5, it will be. necessary to angularly adjust the tool 2 and its mounting. To obviate the repeated readjustment of the table 6 and to One type of such wheels is indicated provide simple effective means for adjusting the tool 2 are the objects of this invention and the detail of the construction will now be described.

Secured to the tail stock 1 by means of a pair of forward bolts 9 and a rear bolt 10 is a casting 8 having a broad, flat, upper face 8', serving as a broad base or support for a holder member proper 11, within' the arms 11 of a forward yoke portion on which is rotatably mounted a dresser 2. This holder member 11 has a broad, flat cooperating bottom face 112 by means of which andthe bolts 12 and 15 the holder is secured to the casting 8 in a very rigid and stable manner. Y A boss for the bolt 12 is indicated by the ordinal 13,- and an elongated transverse slot formed in the rear end of the holder member 11 is indicated by the ordinal 14. The bolts 12 and 15 are rigidly secured in the casting 8 and locked by means of a pin 16 intersecting said casting and the two bolts, as is well understood by those skilled in this art. rllie holder member 11 is jouriialed upon the stem of the bolt 12 so that the holder member is angularly adjustable about the axis of the bolt l2. The elongated slot 14 allows for this angular adjustment of the holder meni-v ber 11, and by means of the nut 15', the holder member 11 is rigidly secuied in any desired angular position.

Upon the rear ofthe casting 84 is indicated by the line 1? a central plane perpen-v dicular to the planes of the ways 5,. and4 a graduated scale 18 formed upon tliei'earof the aiigularly adjustable holder member 11 serves to indicate when saidholder member has been adjusted an amount siifiicientto equal the angularposition of the table G indicated by a graduated scale 4" shown in Figure 1. I f

By means hereinbefore described and plainly shown upon the accompanying drawing, it is evident that the `holder member 11 is very solidly mounted upon the casting 8 and consequently upon the tail stock 1; that due to the broad base upon whichv the holder 11 is mounted and the rigid iii-annex.- iii which the same is held said holder and consequently the wheel `dresser 2 will not shake or chatter during the operation of the dresser;

and that tlieliolder and dresser can be adjusted to an angle necessary to compensate for the angular position of the table 6, depend-iiig upon the character of the work il fr which is being ground. Consequently, whenever it is desired to` dress the wheel 3, the latter is backed away; and then the table (S moved forward to bring the dresser Q directly in front ofthe periphery of the wheel 3,

e whenthe latter canbe moved forward to Contact with the dresser 2, in which position the latter will evenly dress across the entire surface of the periphery of the wheel 3.

It follows that the angular adjustment of the table Grand the dresser `2 need not'Y be changed until ra-A different typel of worl 1 is being ground Aiii the grinding machine.

lvVliat I claim is:

1.4v ln a,grindingVmaeliine, the combination with a grinding wheel; of a work support comprising a table adjustableabout a vertjical axis, and. work holding ymeans thereon comprising a head ',stockand a tail stock;v

and a wheel dressing. .tool mounted upon said tailistock and*l adjustable about a verticalaztis with respect thereto.,

2.,A mountingnfor Qwheel dressers, com prisinga table, the latter being. adjustable about a vertical4 axis. and Vformed with a scale indicating tlie'amoimtof angular adjustment; work holding means ony saidtable comprising a head stocli and a tail. stock.; anda dressing itoolliolder member mounted upon said tail stock and adjustable with respect to said table abouta substantially vertical axis, said holderV member .being pro-l vided ,witliascalemdicating the amount of D1 Brama.
