CAR-AXLE BOX.
SPECIFICATION forming part of Letters fateiit No. 325,668, dated September 8, 1885.
Application filed November 14, 1884. (N0 model.)
To all whom zit may concern.- 4
Be it known that we, EDWARD J. FRos'r, of Philadelphia, in the State of Pennsylvania, and WILLIAM Dawson, of Montgomery county, in said State, have invented certain new and useful Improvements in Lubricating Devices for Oar-Journals, 8:0.
The following is aspecification of our said improvements, reference being had to the accompanying drawings, wherein Figure 1 is a vertical longitudinal section through the journal box and lubrieator on a line with the axis of the journal. Fig. 2 is a similar section on the line as a: of Fig 3; and Fig. 3 is a vertical transverse section on the line y y of Fig. 1.
In said drawings, A represents the journal of a car-axle, above which is the brass B, upon which the truck-fra1ne rests in the usual manner. G is the journal-box, the bottom of which is extended downward, forming a semi-cylindrical trough, D, with a horizontal inner flange, d at, extending along each side.
In addition to the usual door, E, the box 0 has a circular opening below said door, closed by the screw-cap F.
The lubricator proper consists of a number of disks, a a a, preferably of felt or similar absorbent material, arranged upon a central shaft, b, in such manner as to form a continu ous cylinder or roll. The disks are clamped together by means of the fixed rigid washer c, of metal, near one end of the shaft 6, and the screw-nut g and washer it near the other end, it being also desirable to construct the two disks which are at the respective ends of the series of more rigid material than the intermediate ones to prevent crushing or bending. For this purpose we have found the material commonly sold under the name of vulcanized fiber well adapted.
The ends of the shaft 1) are supported in bearings c c, formed in each end of an open rectangular frame, Gr, whose width is such as to allow it to fit snugly in the lower portion of the journal-box 0 above the flanges d d. This frame Gis mounted upon two semi-elliptical springs, H H, secured thereto on each side and resting upon the flanges (1 cl, the springs being so arranged as to hold the upper surface of the roll of disks a tightly against the bottom of the journal A, while the lower portion of the roll extends into thcdepending trough D of the journal-box O.
The roll is inserted in position through the circular end opening of the journal-box, and the cap F is screwed on, after which oil or other lubricating material is poured through the door E into the trough D until the roll is thoroughly saturated and the trough is full.
The pressure of the springs H being such as to bring the roll into frictional contact with the journal A, it is rotated by the revolution of the latter and constantly feeds the lubricant thereto. revolved positively by any ordinary form of gear attached to the journal A, but we prefer the method described as being most simple and efficient.
We are aware that it is notnew to support a lubricating-roll upon spiral springs arranged at the four corners of the roll-frame, so that the roll itself shall be pressed upward into contact with the journal. We therefore do not claim, broadly, such a device. The novelty of our invention consists in supporting the roll-frame upon elliptical springs resting on open ledges along the sides of the journalbox. This arrangement is much less likely to be injured than the old device, since where one of the four supporting-spirals was broken or bent the others would become inefficient to maintain the roll in contact with the journal.
The simplicity of construction of our device and its facility for removal and replacement also distinguish it from the older apparatus above referred to.
Having thus described our invention, we claim- The combination, with the journal and the journal-box, of the receptacle D, forming the bottom of said j ournal-box, the lateral flanges at (Z, the frame G, having elliptical springs H H, which rest upon said flanges, and the roll of absorbent material journaled in said frame, substantially as set forth.
