\ v CAR-AXLE-BOX BRASS.
SPECIFICATION forming part of Letters Patent No. 340,361, dated April 20, 1886.
Application filed February 8, 1886. Serial No. 191,164. (No model.)
To all whom it may concern:
Be it known that we, DANIEL REYNOLDS and J OSEPH S. MURRAY, both of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Brass Bearing for Journal-Boxes, of which the following is a full, clear, and exact description.
The object of our invention is to provide a simple, inexpensive brass bearing for the axles of cars or other vehicles, and for other rotating shafts bearing a weight or load, and by the use of which brass bearing friction and wear may be reduced, lubrication made more effective, and hauling or driving power may be economized.
The invention consists in certain novel features of construction of the brass bearing, all
as hereinafter fully set forth. o
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
I Figure 1 is a side elevation of one end of a railway-car axle and a longitudinal sectional elevation of a journal-box and one of our improved brasses adjusted therewith as in use. Fig. 2 is an end view of the axle and brass, the latter being partly broken away and in section; and Fig. 3 is a perspective view of the brass bearing.
That portion a of the brass bearing A which rests on the journal or arm I) of the car-axle B is made much narrower than usual in brass bearings or brasses of this character, and so that it covers only about one-fifth of the surface of the axle-journal, instead of almost onehalf the surface of the journal, as the common broad brasses do. Consequently there is very much less wear on the brass and axlearm, and the friction is very materially reduced, allowing a given weight or load in a car to be moved easier and with less power; and there also is effected a large saving in the metal required for the brasses-say about one pound for each bcaringwhich makes a material reduction in the cost of our brass bearings over the common ones with broad semicircular bearing-surfaces. The upper or head portion, a, of the brass A extends at each side beyond the part a of the brass, thereby forming overhanging sides a a", and the top of the brass A is convexed lengthwise and cut away to form the central boss or bearing, (i on which the weight of the load is sustained through or at the top of the journal-box, and this recessing of the top of the brass also provides a rim or flange, a, all around the four edges of the brass, to hold the oil and direct its downflow through side grooves onto the axle-arm, as next described.
In each of the overhanging side parts a of the brass A are formed, at or near each end of the brass, the vertical grooves or notches a which extend inward nearly to the part a of the brass and allow the oil poured into the journal-box on top of thebrass through the oil-hole O to flow through them directly onto the surface of the axle-arm on its way to the lower part of the box, where the oil is absorbed by the waste, wool, or other material placed at the bottom of the box for the purpose. The oil-passages a will not choke up, 'as do the small oil-holes made through the body of ordinary brass bearings; hence the brass bearing A never need be removed to clean out the oil-passages.
We show the brass bearing A held over the axle-arm b within the journal-box by a forked or slotted key, D, which enters in a circumferential. groove, d, in the axle; but the brass may be held to place on axles or rotating shafts by any other approved devices, as will readily be understood.
Having thus fully described our invention, we claim as new and desire to secure by Lettel-s Patent- 1. The brass hearing A for journal-boxes, made with a narrow portion, a, adapted to the journal, and with a broad top providing sides a a overhanging part a, and having vertical notches or oil-passages or, substantially as and for the purposes herein set forth.
2. The brass bearing A for journal-boxes, made with a narrow portion, a, adapted to the journal, and with a broad top providing sides a cfl'overhanging part a, and having vertical notches or oil-passages c and the top of the brass A made convexed lengthwise and recessed to provide a central bearing, a, and an edge rim or flange, a, substantially as and for the purposes set forth.
