CAR-AXLE.

SPECIFICATION forming part of Letters Patent No. 368,547, dated August 16, 1887. Application filed April 4, 1887. Serial No. 233,605. (No model.)

To all whom it may concern:

Be it known that I, EDGAR PEOKHAM, of Syracuse, in the county of Onondaga, in the State of-New York, have invented new and useful Improvements in Oar-Axles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of caraxles which are provided with detachable journal-bearings of the form of sleeves slipped onto the ends of the axles for the purpose of preserving the axle and admitting of renewing thejournal-bearings thereof when required.

My present invention consists in an improved construction and combination of parts which facilitate the removal of the journalbearings and are also adapted to more securely retain the same on the axle while in use.

The invention is fully illustrated in the annexed drawings, wherein- Figures 1, 2, and 8 are longitudinal sections of oar-axles embodying my improvements. Fig. 4 is a detached perspective view of the journal-bearing. Fig. 5 isa perspective view of the collar by which the said journal-bearing is retained on the axle, and Fig. 6 is an end view of the axle as constructed in the manner shown in Fig. 2 of the drawings.

Similar letters of reference indicate correspondin g parts.

A represents the car-axle,formed preferably of wroughtiron.

B denotes thejournal-bearing, which consists of a tube mounted detachably on the end portion of the axle, and is preferably composed of steel and case-hardened.

0 represents a collar, which I rigidly secure to the end of the axle, preferably by shrinking it thereon. Said collar abutting against the end of the journal-bearing B serves to securely retain the same on the axle.

To prevent the journal-bearing from turning on the axle, I form the outer end thereof with notches n n or other suitable clutch-face, and form the adjacent face of the collar 0 with lugs or projections looking into the notches n n of thejournal-bearing B.

To facilitate the removal of the journalbearing from the axle, I taper the end portion of the latter from the outer face of the wheel toward the end of the axle and taper the interior of the tubular journalbearing B correspondingly. By drilling ahole, c, in the axle at the rear end of the journal-bearing B, as shown in Fig. 1 of the drawings, and driving into said hole a wedge or key, thejournal-bearing B is readily forced outward and loosened from its seat on the axle, so as to permit of readily removing said journal-bearing.

The retaining-collar C is to be previously removed from the axle by heating said collar, so as to expand it and loosen it on the axle sufficiently to permit of driving the collar off from the axle.

The tapered end portion of the axle I prefer to terminate with a circumferentially-reduced nipple, D, and shrink the collar 0 on said nipple,thus requiring the collar to be enlarged in thickness and imparting increased strength to the same. The usual shoulder on the inner end of the journal bearing I form of a separate collar, F, which I also shrink onto the axle immediately back of the inner end of the journal-bearing B, as represented in Fig. 3 of the drawings. When the axle is thus constructed, the car-wheel will either have to be pressed onto the axle before the aforesaid collar is shrunk on the latter or the car-wheel has to be constructed with a hub which is detachable from the body of the wheel and divided diametrically and clamped onto the axle. In order to obviate undue enlargement of thejournal-bearings, I form the axle with circumferentially-rabbeted end portions, A,as shown in Fig. 2 of the drawings, and slip the tubular journal-bearings onto the said rabbeted portions of the axle.

On street-car axles,which require an extra collar on the extremity of the axle, I provide the free end of the nipple D with a circumferential rabbet, a, and shrink on the rabbeted portion a secondary collar, 0, which is sufliciently remote from the collar 0 to form the desired bearing 72 between them.

If desired to further insure the attachment of the secondary collar 0 to the nipple D, a washer, d, of sufficient diameter to lap onto the exterior of the said collar,may be secured to the end of the nipple by a tap-bolt passing the notches a a, substantially as described and shown.

2. The combination of the axle taperedfrom the outer faces of the wheels toward the ends of the axle, tubular journal bearings mounted on the tapered end portions of the axle,and collars permanently secured to the ends of theaxle and abutting against the tubular journal-bearin gs, substantially as described and shown.

3. The combination of the axle tapered fromthe outer faces of the wheels toward the ends of the axle and terminating with the nipples D D,the tubular j ournal-bearings B B, mounted on the tapered end portions of the axle, and collars permanently secured to the aforesaid nipples, substantially as described and. shown.

4- The combination of the axle tapered from the outer faces of the wheels toward the ends of the axle and terminating with the nipples DD,the tubular journal-bearings B B,mounted on the tapered end portions of the axle, and collars permanently secured to the nipples and of a greater diameter than the exterior of the aforesaid journal bearings, substantially as shown and described.

5. The combination of the axle formed with tapered end portions terminating with nipples D D, tubular journal bearings B B, mounted on said tapered end portions and provided with notches n n at their outer ends, and collars O O, permanently secured to the nipples and provided with lugs looking into the aforesaid notches, substantially as shown and described.

' 6. The combination, with an axle, of tubular journal-bearings detachably mounted on said axle, and collars shrunk on the axle at opposite ends of each of said j ournal-bearings, substantially as described and shown.

7. The combination of an axle formed with tapering end portions, tubular journal-bearings formed cylindrical externally and tapered internally to correspond to the end portions of-the axle and detachably mounted on the latter, and collars shrunk on the axle at opposite ends of the said journal-bearings, substantially as described and shown.

8. The combination of an axle formed with tapering circumferentiallyrabbeted end portions, tubular journal-bearings tapered internally to correspond to the said end portions of the axle and mounted detachably thereon, and collars shrunk on the ends of the axle and abutting against the ends of the aforesaid journal-bearings,substantially in the manner specified and shown.

9. The combination of an axle formed with tapering circumferentially-rabbeted end portions terminating with circumferentially-reduced nipples, tubular journal-bearings tapered internally to correspond to the aforesaid end portions of the axle and mounted detachably thereon, and collars shrunk on the nipples and abutting against the ends of the said journal-bearings, substantially as described and shown.

10. The combination of an axle formed with circumferentially-redueed nipples on its ends, tubular journal-bearings mounted detachably on the axles back of the nipples, retainingcollars shrunk on the nipples and abutting against the ends of the said journal-bearings,

and secondary collars shrunk on the ends of the nipples remote from the retaining-collars, substantially in the manner set forth and shown. In testimony whereofI have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York. EDGAR PEGKHAM.
