J'. WENDELL COLE, or BROOKLYN, NE YORK, AssieNon To THETANITE COMPANY, OF STROUDSBURG, PENNSYLVANIA.
IMPROVETMENT IN MACHINES FOR DRESSING WHEELS, ac.
Specification forming part of Letters Patent No. I 39,774, dated J une 10, 1873; application filed December 7, 1872.
CAM: C.
To all whom it may concern:
Be it known that I, J. WENDELL COLE, of the city of Brooklyn, in the county of Kings and State of New York, have invented certain Improvements in Machines for Dressing Wheels and other circular bodies of transverse curvature on their peripheries, of which the follow-' ing is a specification:
This invention is mainlydesigned for turnin g or dressing emery or other grinding wheels of transverse curvature on their peripheries, applicable to the grinding or dressing of the bearing-surfaces of journal-boxes. The invention generally consists in acombination, with a revolving shaft or carrier of the wheel or body to be dressed, of a diamond or other outandFig. 2 a transverse vertical section of the same.
Similar letters of reference indicate corresponding parts.
A is the main frame, havm g journal boxes or bearings b b for support of the shaft or carrier B, by which the emery or other grinding wheel 0 to be dressed is rotated. D is an upper bed or table, carried by the frame A, and through which the wheel 0 projects. This table D carries the swinging diamond or other cutter E, and may be vertically adjustable by means of separate or suitably connected screws 0 c and guides d d to adapt the cutter E to different diameters of wheels; or the wheel carrier B may be similarly adjustable relatively to the cutter E, for the same purpose. F is the swinging tool or cutter .holder,
- of bail-like construction, and arranged over or outside of the periphery of the wheel 0, and
sects at right angles the planein which the axis of the wheel 0, or its carrier B, lies; or,
in other words, corresponds with the plane of, a
the wheels rotation. A
The bearings e e of the bail-like tool-holder F are represented as arranged within or on having the axial line of its bearingse e ina plane which, being extended, crosses or intera sliding bed, G, constructed to fit ways ff upon the table D, disposed in directions parallel with the plane of the wheels rotation to allow of the cutter E being shoved up to and from the work for the purpose of graduating its action on the wheel, and of centering it thereover; but said cutter-holder may be arranged to swing in fixed bearings connected with the table D, and the cutter E be either permanently or adj ustably centered relatively to the axialline ot' thewheel or, again, the
latter, if preferred,:may be carried so as to be correspondingly adjustable relatively to the cutter. I i y The diamond or other cutter E is adjustable, as by a screw-thread on its shank, or otherwise, in a radial direction, within or through its :holder, to vary the distance of its cutting point or edge from the axial line or center of the holder, and so to change the curvature of a its cut.
In the operation of the machine it is only necessary, in order to efi'ect a perfectly-true dressing of the wheel, both circumferentially and as regards the transverse curvature of its periphery, to swing the bail-like cutter-holder F by a handle, S, common to it andthe cutter, after the latter has been brought over thecenter of the Wheel backward and forward across the peripheral portion of the revolving wheel. An emery-grinder thus dressed may be used to advantage in grinding the interior or beam in g surfaces of journal-boxes, inasmuch as the same will be found perfectly true, and to conform, on its periphery, to the required curvature of the bearin g; provided thepoint of the cutter be properly adjusted relatively to the axial line of the cutter-holder.
What is here claimed, and desired to be secured by Letters Patent, is
1. The combination, with the revolving shaft or carrier B, by which thewheeltor body to be dressed is rotated,ofthe cutter E and its wheel or body to be'dressed, substantially as bed D and revolving shaft or carrier B, hawking its axis in a plane which intersects the axial line of the cutter holder, essentially as described.
