CAR-AXLE BEARING.

SPEGIFICATION forming part of Letters Patent No. 628,971, dated July 18 1899.

Application filed August 27, 1898. Serial No. 689,639. (No mode1.)'

T0 ctZZ whom it may concern:

Be it known that 1, AUGUST J. VVEIL, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Oar-Axle Bear-' ings, of which the following is a specification.

My invention relates to a certain new and useful improvement in bearings for car-axle boxes, and particularly to the construction of the key thereof.

Heretofore, so far as I am aware, it has been usual to employ a key for holding a separate bearing-piece securely in position in the box, the key and bearing-piece being made in two distinct parts and connected together in various ways. I

The object of the present invention is to simplify the construction of the car-axle bearings by casting the key and the bearing-piece in one integral part and of such a character that it may be changed in its details of construction to adapt it to boxes and brasses of diiferent kinds.

In the accompanying drawings I have illustrated the invention in a simple form, referring to which--- Figure 1 is a longitudinal sectional view of a car-axle box embodying my invention. Fig. 2 is a bottom plan view of the key. Fig. 3 is a detailed enlarged sectional view of one end of the key.

Referring to the drawings, in which like letters of reference denote corresponding parts in all the figures, A designates the journalbox, which may be of any well-known construction, the particular form illustrated being employed by me here simply for the purpose of showing the application of the invention. The brass O is arranged within the box to engage the axle Bin the usual manner, and this brass has heretofore been maintained in its proper relation to the axle by means of a separate bearing-piece interposed between the brass and a key secured within the box and having a certain freedom of movement in the key; but by my present invention the brass is held in its proper position by my peculiarly-formed key D. This key consists,

preferably, of a substantially fiat plate provided with side lugs F to engage correspond ing lugs inside of the box and a projection or securing the key in place.

heel G, which engages the lug H on the inner side of the top of the box. The manner of securing the key within the box by means of the aforementioned lugs islcommon in the art,

and it will be understood, of course, that I do not limit myself to any particular method of As I have heretofore stated, the particular construction of the details of my improved key may be varied as desired, the essential feature of the invention comprising a key provided with an integral bearing-surface to engage the brass, and this bearing-surface is preferably of a circular concave form to accommodate the corresponding circular convex bearing-surface of the brass. It is obvious that the edges of the concaved bearing-surface may be extended below the lower face of the adjacent portions of the key or they may be flush therewith, as desired, and other changes in the details of construction may be made without departing from the spirit or sacrificing the advantages of the invention. It will thus appear that by casting the key and the bearing-surface which engages directly with the brass in one piece I reduce the number of parts necessary in the car-axle bearing and avoid all the disadvantages of a number of working parts which have heretofore been connected together in various ways and which are liable to become bound in wrong positions and otherwise get out of order.

In the drawings I have shown the brass provided with a convex bearing-surface and the key with a corresponding concave bearingsurface; but I do not limit myself to this particular arrangement, for it is obvious that the brass may have the concave bearing-surface and the key provided with the convex bearwhat I claim as new, and desire to secure by movementin any direction andalateral move- Letters Patent, is ment, one Within the other, substantially as In a car-axle box, the combination with 21, described. brass having a circular convex bearing-sur- Signed at New York, in the county of New I5 5 face on its upper side, of a key adapted to be York and State of New York, this 26th day of secured Within the box and provided on its August, A.
