" Patented Sept.4;,'190fi.

To all whom it may concern:

Be it known that I,LOU1s BINGELL, a citizen oi the United fitates, residing at Detroit,

county of Wayne, State of Michigan, have invented a certain new and useful improvc ment in Tools for Truing Grindini and Abradin /Vheels and I declare the following to be a hill, clear, and exact description of theinvention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accom panying drawings, which form apart of this specification.

This invention relates to tools for truing grinding and abrading wheels.

It has for its object an improved tool for the purpose specified. 1

In the drawings, Figure 1 is a plan view of Fig. 2 shows a pinion-actuator inplace of the quadrant-acthator of Fig. 1

1 The tool consists of a tubular body 1, in which'there is contained a tool-head carrier 2 ,provided on one side with a'rack 3 and carrying at one end .a head 4, which is also tubular, with the openingnthrough it at right an les to the opening t on 11 the body part 1.

he head'part 4 is provi ed at one end with bearings 5 for a hand-actuated screw 6. The

screw engages in the stem 7 bf'thc abrading tool, WlllCllconsists of a number of corrugated disks 8, mounted on ashait 9, which shaft 9 is journaled in a fork 10 at the end'of the tool-stem 9-.

The tubular body part 1 is preferably made in two parts, secured together bybolts, and

1 the tubular head part is also preferably made in twoparts, secured together by bolts. The

carrier 2 is rectangularin cross section or screw-hole in the stem 7. On the front side of 'pris atic. -So,'also,the tool-stenr7 isrectangular in cross-section or prismatic. Y Thebody' art 1 is-provided with-handle-sup ort proections 11, in which there is pivote a hand- I love 12, having an arched rackv 13." The rec 13 engages with the rack 3 on the carrier 2. The screw 6 engages in'a threaded the body 1 opposite the handle-support projections 11 are secured two brackets 14 and 15, provided with circular perforations, and

through the perforations extends one branch 16 of a squaring-guide whose branch 17 can be'swung to a position of arallelism with the axis of the stem 7 but if eft without sup port the arm 17 will drop (when the tool is in position for work) to a position at an angle to the'stem 7, where it is no longer in a position to interfere in any way with the proper work ing of the tool. Its useis to square up the tool with the stone to be treated 1n order that the tool stem 7 may be projected to the proper distance through the head 4 to engage properly with the face of the stone.

From the body 1 there rejects upward a trunnion 18 and downward a trunnion opposite the trunnion 18, (which is not seen in drawingsJ in use one of the trunmons is seated in a bearing in the frame of the stoneto be trueci,

right or to the left of the handle 12 and the body 1; The workman selects that position which is best adapted for the articular stone under. treatment, and the too works equally well either side up After thetrunmon is seated in its bearing the carrier 2, is moved until the axis of the tool-stem 7 is in salinement with the normal to the face of the stone to be trued. This face of the stone may be at right angles to the side face of the stone or it may be at an'angle thereto. The tool will work to true up elther face with equal facil it as, for example, it will time u the face the stone shown in dotted lines.

By oscillating the handle 12 the, truingventire face ofthestone and are held truly the straight line in their path of travel.

wheelsa' im'on-actuator 18, driven by hand-wine 19, is em loyedr The carnage. 22'ismade longer, an the raclr. 23 is placed on the under side. The pinion issupported same, the ran e of movement eater. Whaii llclaim is- 1. In a tool for truing up abrading-wheeis, the combination of a body portion, a carrier enga "n therethrough, means supported by said. y portion and on aging said carrier whereby its position wit respect. it said body portion may be regulated, a tool-carryhag'head at one end of said carrier, and an a justable'stem provided with'an abrasive end portion engaging through said head transversely to the longitudinal axis of the carrier, substantially as described.

in combination with a body portion, a carrier passing therethrough, a mo -segment pivotally supported by said body portion and en 0 the stone shown in full lines or t e face disks 8 are carried in reciprocation across the;

axis of its possible movement being perpendicular to-the lengthwise axis of the carrier, eubsm-i hieily as described.
