BRASS FOR CAR- SPECIFICATION forming part of Letters AXLE" BEARVINGS.
Patent No. 292,452, dated January 22, 1884.
' Application filed March 6, 1883. (No model.)
To aZZ whom it may concern:
Be it known that 1, JOHN WALLACE, of the city and county of Albany, in the State of New York, have invented certain new'and useful Improvements in Brasses for Car-Axle and exact specification. My invention relates to improvements i brasses for car-axle bearings and other j ournalboxes that contain an anti friction filling and it consists in providing said brasses and boxes with a filling of compressed paper or paper-boards, as hereinafter set forth.
The object of my invention is to provide for car-axle and other bearings a cheap,effective, and durable anti-friction filling that will be readily renewable at'slight cost. This object I attain by means of the construction illustrated in the accompanying drawings, which form part of this specification, and in which Figure 1 is a planview of a car-axle brass- .A, which I preferably make of bronze, is in the form of a hollow shell or case, having one of its ends made open, and provided with a detachable plate, a,which closes over the open end and completes the surrounding wall for the chamber that is formed in said brass for containing the anti-friction filling. The plate a is secured in place by meansof screw-bolts a, that are inserted in longitudinal bosses a, which are formed at opposite sides of the chamher for containing the filling material and ex tend the full length of said chamber. The said bosses are undercut, as shown in Fig. 3, and form in effect a dovetail for securing the filling-pieces in place. The anti-friction filling is composed of the filling-pieces B, which are made of compressed paper or paper-board that,while saturated with water or other suit able liquid, has been subjected to a pressure of about eight thousand pounds to the square foot for the .purpose of condensing and hardening it. The said filling-pieces are formed to fit transversely into the chamber of the brass A, and their ends are provided with the concave portions b, which fit around the bosses a so as to dovetail between them. The upper edges of said filling-pieces are made with a slight excess of material, as indicated by the space between the full and dotted curved lines in,Fig. 4, so as to provide for the finishing of .the filling to the required concavity after the pieces are secured in place. The filling-pieces B are inserted into the chamber of the brass A until the successive thicknesses fill the entire chamber, and then the closing-plate a is fixed in place to secure the said filling-pieces in said chamber. The brass is then placed under a revolving cutter, which finishes the filling to the required curvature.
With an equal quantity of lubricant, brasses provided with my filling will endure as much service, and run with as little,if not less, heating,as those that are filled with the best antifriction metals, while the cost for filling and refilling them is but an insignificant sum in comparison with the cost of the metal fillings.
I claim as my i1ivention- 1. As animprovementin brasses forcar-axles and other bearings, the chambered shell A, containing a filling of compressed paper or paper-board thesaid paper or paper-board being out into shape, substantially as described, to form the filling-pieces B, which are then fixed edgewise in the chamber of the shell A, as and for the purpose herein specified.
2. The combination, with the chambered shell A, provided with a detachable plate, a, as herein described, of the filling-pieces B, composed of compressed paper or paper-boa rd,as and for the purpose herein specified.
