APPARATUS FOR DRESSING AXLE-ARMS FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 235,373, dated December 14, 1880.

Application filed September 15, 1880. (ModeL) To all whom it may concern:

Be it known that I, ROBERT E. -MILLER, of Plantsville, in the county of Hartford, and in the State of Connecticulyhave invented certain new and useful Improvements for Apparatus for Dressing Axle-Arms of Wagons;

and I do hereby declare that the following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making a part of this specification, in Which-- Figure 1 is a perspective view of the parts of my apparatus separated fromeach' other. Fig. 2 is a like view of the rear side of the cutter-head. Fig. 3 is a central longitudinal section of said apparatus as arranged for use in dressing the shoulder at the inner end of an axle-arm, and Fig. 4 is a like view of the same as arranged for operation upon the outer end of said axle-arm.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is toenable the unnecessary end -shake of a wagon -wheel caused by Wear to be obviated and said wheel restored to its original condition in such respect without rendering necessary the removal of the old box and its replacement by a new and longer box; to which end it consists, principally, in the means employed for journaling the cutter-head to or upon an axlearm, substantially as and for the purpose hereina ftcr shown.

It consists, further, in the means employed for adjusting the cutter to position, substantially as and for the purpose hereinafter shown and described.

It consists, finally, in the construction and combination of the parts of the apparatus, substantially as and for the purpose hereinafter specified.

In the annexed drawings, A represents a metal disk, provided upon one side with a hub, A, that has the form of a hollow cylinder, is reduced in size from its outer en d nearly to the rear face of said disk, and is provided within axial opening a of said hub extends through said disk.

Within the disk A is provided a radial rectangular opening, (1 that contains a block, C, which is capable of motion therein toward or from the center of said disk, and is moved to and held in such position by means of a spiral spring, D, that is placed between its inner end and the inner end of said opening, and a screw, E, which passes through the periphery of said disk into the outer end of said opening and bears againstthe outer end of said block. When said screw is turned inward said spring yields and permits said block to be moved in the same direction, while upon turning said screw outward said spring expands and moves said block in alike direction.

The block C is provided with an opening, 0, which receives a bolt, F, that has upon its outer end a flat head, within which is a rectangular opening, f, that receives and contains a cutter, Gr, having in cross-section a corresponding shape. The rear end of said bolt is threaded and passes through a washer, H, which extends at each side beyond said opening 0, and bears upon the rear face of the disk A, while upon said threaded end is placed a nut, f, by means of which said bolt may be drawn rearward through its opening and caused to clamp said cutter G firmly against the outer face of said disk. The cutter G has a square point, and in order that it may be adjusted so as to cause its cutting-edge to have the requisite angle with relation to the surface being cut, a set-screw, I, is arranged within a lug, a that projects from the face of the disk A, with its point in contact with the heel of said cutter, so that by moving said screw within its bearin g the inner end of said cutter will be moved forward or permitted to move rearward until the necessary adjustment is secured.

The rear reduced portion of the hub A fits loosely into a cylindrical sleeve, K, which has about twice the length of such part, and is provided with two or more radially-arranged set-screws, k, that may be caused to impinge upon the periphery of the sectional ring B. Said ring has such interior dimensions as to enable it to turn freely within its groove a when said set-screws have pressed its sections firmly together, by which means said hub A and sleeve K are journaled together and permitted to have free independent rotation, while held securely together longitudinally.

The cutter-head A, being provided with radial handles A, is used as follows, viz: A sleeve, L, corresponding in interior dimensions to the exterior of an axle, M, near its center, and having exteriorly such size and shape as to permit the sleeve K to pass over the same, is placed upon said axle-arm and driven firmly upon its tapering periphery, after which said cutter-head is passed over said sleeve L until the cutter G is in the desired position with relation to the inner shoulder, m, of said axlearm, when four radial set-screws, k, provided near the rear end of said sleeve K are turned inward and caused to firmly clasp said sleeve L. The cutter-head A is now journaled upon a firm bearin g, and may be freely rotated, when by moving the cutter G inward the cuttingedge of the latter will be brought into contact with the shoulder m of the axle-arm M, and by continuing such operation said shoulder will have its face cut away so as to remove all traces of wear and to cause said face to present a straight, smooth surface. The cutterhead is now reversed so as to bring its cutter into position for operation upon the outer shoulder, m, of the axle-arm M, and said shoulder cut back until said arm has the necessary length, after which said cutter-head is moved sufficiently forward to enable said cutter to impinge upon and cut off from the end of the screw in all surplus stock. Nothing now remains but to cut the screw-thread upon said end m up to the new shoulder m, which is done by means of an ordinary die-plate.

As the nuts ot' axle-arms sometimes require to be tapped out to correspond to the newlytllreaded end 1):, it is necessary that provision should be made for holding said nuts in position during such operation, for which purpose I provide within the disk or cutter-head A several square openings, a, having different dimensions, so as to accommodate nuts having different sizes. A nut being placed in one of said openings will be securely held and may be retapped with ease.

From use axle-arms become worn tlat in places, and in order that such wear may not interfere with the centering of the cutting apparatus, and to enable the taper of different axle-arms to be fitted, old boxes are cut into suitable lengths and have their exteriors made straight and round, and are then used in place of or within the sleeve L, several of such sleeves being provided for each apparatus.

The apparatus described furnishes a convenient means whereby the operations described may be easily and neatly done by any person possessing ordinary skill in the use of tools, at any place, and without other derangement of a wagon than the removal of its wheels.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1. As a means for journaling the cutterhead upon an axle-arm, the sectional ring B, fitted into and adapted to revolve within a groove, 0, in the hub A of said head, the sleeve K, provided with the radial screws 1: and k, and the sleeve L, fitted upon said axle-arm and within said sleeve K, said parts being combined in the manner substantially as shown.

2. As a means for adjusting the cutter G to position, and in combination therewith, the block 0. titted into the radial opening a of the head A, the spring D, and set-screw E, arranged to bear upon opposite sides of said block, the bolt F, having the openingf and nut f, the washer H, and the set-screw I, all arranged substantially as and for the purpose shown and described.

3. The combination of the disk A, provided with the hub A, groove a, axial opening a, radial opening a and handles A, the sectional ring B, the sliding block (J, the spring I), the set-screw E, the bolt F, having the openingf and nut f, the cutter G, the washer H, the set-screw I, the sleeve K, provided with setscrews 7: and Ir, and the sleeve L, substantially as and for the purpose specified.

In testimony that 1 claim the foregoing I have hereunto set my hand this 9th day of September, 1880.

R. R. MILLER.
