GEORGE F. CALLAGHAN, OF BALTIMORE, MARYLAND.
AXLE-ARM ROLLER-BEARING.
SPECIFICATION forming part of Letters Patent N 0. 615,662, dated December 6, 1898,.
Application iilecil August S, 1898.
The object of the invention is to provide a roller-bearing sleeve of such construction that it may readily be applied to the arm or spindle of an axle and retained thereon whenever the wheel is removed.- Access can be had to a roller-bearing of this construction for readily cleansing it.
The invention is illustrated in the accompanying drawings, in whichM Figure l is a view of the arm or spindle of` an axle with the sleeve roller-bearing and wheel-hub in section. Fig. 2 is a side view of the axle-arm and sleeve-rollers as seen when the wheel is removed. Fig. 3 is a crosssection of the axle-arm and rollers on line3 3 of Fig. 2. Fig. 4 is a diametrical section of the small collar. Fig. 5 shows two views of the large collar. Fig. 6 shows two views of a roller.
Referring to the drawings, it will be seen that the wheel-hub A is of ordinary construction-in fact, any kind of hub may be used. A suitable box B is in the hub, and this box must be large enough to take over the sleeverollers that are secured on the axle-arm C. A collar d is first slipped onto the axle-arm and must fit snugly the large end of the arm and abut against the permanent collar or flan ge e, adjoining the axle C. The back f of this large collar is flat, so as to fit against the permanent flange e; but the front has an inward bevel edge g, or, preferably, instead of a straight bevel on the inner part, a concaved or hollowed-out ring-face, as shown clearly in Fig. 5. This collar may be made fast on the large end of the arm C by screws passed through the collar. In the present instance the back of the collar has a lateral rim-flange f', provided with several holes h for screws 7L to enter corresponding holes in the permanent flange e on the axle. The inward=concaved ring-face before described forms an an nular undercut groove around the axle-arm Serial No. 688,064. (No model.)
ward-concaved ring-face like that already described on the large collar. The inwardconcaved face for the rear set J of rollers is designated by g and the like face for the front set J is designated by g2. The exterior surface of the sleeve Zt has its central portion between the two ends ofreduced size, as at Z, and the sleeve is retained rigidly on the axlearm by screws m.
A collar n is secured on the small end of the axle-arm and has an inward-concaved face g3. (Shown more clearly in Fig. ll.) This face is for one end of the front set J of rollers. In this instance the small collar n is made fast on the end of the axle-arm by a screwthread connection o.
The extremity of the axle-arm has a screw thread p, which receives the ordinary nut q, that keeps the wheel on.
By referenceto Figs. l and 2 it will be seen each set of rollers J J constitutes a loose sleeve, secured on the axle-arm C by the rounded ends of the rollers being loosely clamped by the inward-concaved faces or annular undercut grooves of the collars d n and sleeve k. In operation all the rollers in one set are free to turn around the axle. By employing the stationary central sleeve 7c,
which is reduced in size exteriorly between` its ends, it is possible to make the rollers short,and short rollers operate more smoothly. The end collars and the central sleeve are of less diameter than the axle-arm and rollers, whereby only the rollers come in contact with the box B in the hub.
When the wheel is removed from the axlearm, the rollers remain on the latter and have the appearance shown in Fig. 2. This construction enables the rollers to be easily, thoroughly, and quickly cleaned, an operation that is attended with difficulty and un satisfactory results where the rollers are sen cured in the hub-box.
Having thus described my invention, what having a rounded end, the said ends being I claim :lsloosely clamped by the inWandly-oonoaved The combination of tu axle-arm; two oolring-faces. lars one of which is rigidly secured to one In testimony whereof I ailx my signature 5 end of said arm and the other to the other end in the presence of two Witnesses.
of the same and each collar provided with an T inwardly-concaved ring-face; aoentral sleeve GEORGE F' OALLAGHAB' rigidly secured on the axle-arm and having Witnesses: at each end a similar conoayed ring-face; and CHAPIN A. FERGUSON, ro two independent seis of rollers, each roller l CHAS. B. MANN.
