GRINDING DEVICE.

Application filed September 27, 1922, Serial No. 5 0,900; Renewed November 2, 1923.

To all whom it may concern:

Be it known that I, FRANK LAPE, a citizen of the United States of America, and resident.of lVilkes-Barre, in the county of Luzerne and State of Pennsylvania, have in vented certain new and useful Improvements in Grinding Devices, of which the following is a specification.

This invention relates to grinding machinery, and particularly to a device intended for use in dressing the peripheries of friction disks or wheels, the said invention having for an object the provision of novel means whereby wheels of the character indicated can be dressed without removing them from their installations; and the said invention is more particularly intended for use in connection with friction wheels used in transmissions of automobiles and the like.

It is an object of this invention to provide novel means whereby a friction wheel that is shiftable may, while it is in rotation, be ground to remove any irregularities in its periphery, in order that the said wheel will run smoothly in association with its coacting member in a friction drive; and the said invention furthermore contemplates the production of a device of this kind having adjustable relation to the wheel or its bearings, in order that it may be set to dress the wheel to a predetermined extent.

A further object of this invention is to produce a grinding device of the character indicated which can be applied to or removed from the frame structure of automobiles, or other structure in which the friction wheel is mounted.

IVith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a plan view of a friction drive, associated with a frame intended for use in an automobile;

Figure 2 illustrates an underneath plan view of the grinding tool and its mounting;

Figure 3 illustrates a sectional view through the cross member of the frame,

showing a device embodying the invention, in side elevation; and

Figure 4 is a perspective view of the tool or grinding element.

In these drawings 5 denotes a frame, 6 a cross member thereof, 7 a friction wheel, 8 a friction disk with which the wheel coacts, and 9 a wheel shifting mechanism which is conventionally shown and need not'therefore be described in detail. Any means for shifting the wheel axially may be employed for moving the said wheel with respect tothe grinding tool, as will presently appear.

The cross member 6 has an aperture 10 for the reception of a fastening 11, which may be in the nature of a screw, the said fastening having a shank 12 which extends through a slot 13 of the abrading or grinding tool 14. Av washer 15 is interposed between the head of the screw and the said tool, for the purpose of binding it and forcing the said tool against the cross member, in order that it may be held rigidly while the operation proceeds.

The nose or working surface of the tool is preferably rounded as shown at 16, and it is intended that through the medium of the slot in the said tool, it may be adjusted with relation to the periphery of the wheel 7 in order that it will act on the said wheel and dress it so that its periphery will be concentric.

After the tool has been set and secured on the cross member, the shifting mechanism may be operated to cause the wheel to pass the tool while the said wheel is being rotated and this operation will result, if the tool is properly set, in so treating the wheel as to give it a true working surface to cause it to properly coact with its companion friction member.

. The abrading or grinding material of which the tool is made may be varied to suit particular requirements, but necessarily, it must be of some relatively strong material, as will withstand a certain amount of strain and have a high efficiency as a grind- I claim: 1. In a device for truing friction wheels, the combination with a mounting for a wheel, including means for moving the wheel axially, a cross member stationed in spaced relation thereto and parallel with the axis of the wheel, a relatively straight grinding tool having a slot a member extending through the cross member and into the slot of the grinding tool for holding the grinding tool adjustable with relation to the periphery of the wheel and in position at a right angle or oblique with relation to the axis of the friction wheel.

2. In a device for truing friction Wheels, the combination with a mounting for a Wheel, including means for moving the tending through the cross member and L through the slot of the tool for holding the said tool in different positions of adjustment.

FRANK LAPE.
