IMPROVEMENT IN cAR-AxLE Boxias.l

Specliication forming part of Letters Patent No. 153,705, dated August 4, 1574; application led J une 5, 1874.

To all whom it may concer-n:

Be it known that we, WELLsLY W; CRANE and CLARA T. CRANE, of Auburn, in the county of Cayuga and in-the State of New York, have inventedv certain new and useful Improvements in Housing for Car-Axle; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a car-axle housing` or box for the purpose of saving oil as its main feature, as will be hereinafter set forth.

In the annexed drawings, in which Figure 1 is a longitudinal section, and Figs. 2, 3, and 4 detached portions ot' the box and axle- A represents an axle housing or box, which is made, so far as external appearance goes, similar to those now in ordinary use. B represents a recess cast in the housing A, and C is a stop-bar fitted closely into said recess, and secured to the housing by means of bolts D D. E is a wedge-plate, which the stop-bar is intended to hold in position. F is the journalbearing or plummer-block, cut away at G for the purpose of hinging the partition I, its thickness being nearer the outer end of the axle, in order to gain a larger amount of room in the collar-housing. We will now explain the cause of this change of construction. The extreme length of the enlarged portion of the axle K is two inches from the wheel-hub H to the shoulder lc in car-axles now in use therefore, as our improvement is intended to be used on those in use, the partition I is placed back toward the outer end of housing A, in order to obtain the object referred to. J is the axle-journal, and upon the enlarged portion of the axle K is firmly secured the flanged collar L. M is the collar-housing, and a a a the clearances between said collar and the collar-housing, and between the end plate or wall R and the wheel-hub H. O is the cover for the collar-housing, and attached thereto is an inclined flange, P. We will now explain the construction and the functions to be performed by the iianged collar L, the cover M, with the inclined flange attached, theaperture q in the partition I, and their relation to each other. The collar L is constructed in two parts, having two deep anges, a a', said flanges being made sharp, or nearly sharp, at their periphery, leaving a space between said iianges at their junction with the periphery of the body of the collar at z' t. This is done to allow the inclined flan ge P to enter between said lian ges, and allow room for said inclined flange. When the journal-bearings F wear away upward and at their ends, as shown by the dotted lines at w fw, caused by the lateral motion of the car, it will be seen that the clearances n a n are equalized in distance from the collar to the walls of the collar-housing, and the wheel-hub H and the end plate on wall R, for the purpose of keeping the said collar and the aforesaid wheel-hub from coming into contact with the walls of said collar -housings when the ends of the bearing F are endward and outward, caused by the motion of the car laterally, as shown by the dotted lines. The surplus oil from the end of the journal-bearing and shoulder of journal at k is taken by the flange a of the collar L, and ejected upon the cover o. Theinclined flange B is intended to conduct the oil thus thrown upon said cover down between the flanges a a', not allowing any oil to pass the ange a', whereby the waste of oil is entirely prevented. The collar-housing M is relieved of oil by the aperture q in the partition I, and returned to the housing A. The guard-plate W is attached toy the partition I by the bolt e, and is intended to keep the aperture q free from waste or other fibrous :material when such material is used within the housing EI, to conduct the lubricating fluid to the journal J. The flange S is for the purpose of forming a check upon the oil contained within the housing A when the said oil is agitated by the lateral motionl of the car, and y opening is intended to be nearly close to the under side ofaforesaid axle, leaving a space betweenthe upper side of said axle and said opening, to allow for wear upward upon said journal-bearing F. Said space is closed by the plate d, to prevent the ingress of dust.

Now, in order to remove the bearing F when worn and replace it with a new one, the stopbar C must be removed, the wedge-plate withdrawn, and the bearing F lifted upward sufficiently to pass over the shoulder or collar T; This device enables us to place the lower edge of the opening in plate R close to the under side of the axle K, and thereby prevent to a large extent the ingress of dust in that direction.

We are aware that an aperture to relieve the collar housing M of oil, as shown at q in the partition I, is seen in patent of W. W. Crane, dated May 13,1873, and we therefore disclaim this as a part of our invention.

Having thus fully described our invention, what we claim isl. In combination with a housing, A, provided with a wedge -plate, E, the removable stop-bar (3, held in the recess B in the housing by the bolts D D, as and for the purpose set forth.

2. In combination with a housing, A, provided with a housing, M, and journal J, the journal-bearing F cut away at Gr, and the partition I, as and for the purpose specified.

3. In combination with a housing, A, provided with a bearing, F, housing M, and axle K, collar L, provided with ianges a a', cover O, and inclined iange P, as and for the purpose described.

. 4. The guard-plateWand iiange S, in combination with a housing, A, provided with a partition, I, housing M, and an aperture, q, as and for the purpose set forth.

In testimony that we claim the foregoing We have hereunto set our hands this 15th day of May, 1874.
