LID FOR CAR-AXLE BOXES.

SPECIFICATION :forming` part of Letters Patent N0. 644,036, dated Flruary 20, 1900.

Application filed December l, 1899- Serial No. 738,770. (No model.)

T0 @ZZ whom, t ntcty concern,.-

Be it known that I, JOHN W. STEPHENsoN, of No. 520 Euclid avenue, Toledo, county of Lucas, and State of Ohio, have invented a new and useful Improvement in Lids for Car- Axle Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a vertical longitudinal section on the line I I of Fig. 2 of my improved lid for car-axle boxes. Fig. 2 is a front elevation. Fig. 3 is a horizontal section on the line III III of Fig. l. Fig. tis a cross-section on the line IV IV of Fig. l. Fig. 5 is similar to Fig. l, showing a modified form of lid, beinga vertical longitudinal section on the line V V of Fig. 7. Fig. 6 is aside elevation of the same. Fig. 7 is a horizontal section on the line VII VII of Fig. 5, and Fig. 8 is a cross-section on the line VIII VIII of Fig. 5.

The object of my invention is to provide a lid of simple and efficient construction which will tit neatly to its seat on the face of the car-axle box even when the hinge-lug of the box is out of parallel with the edge of the box.

In Figs. l and 2 of the drawings, 2 represents the car-axle box, having the usual hingelug 3. 4. is the pintle or hinge-pin, and 5 is a closing-arm having hinge-lugs 5 5', through which the pin passes. 6 is the axle-box lid, which is connected to the closing-arm 5 by a stud 7 on the arm, whose head fits loosely in an open socket 8 on the face of the lid. The lid is also connected loosely at the hinge portion of the box to the closing-arm 5 or to the hinge-pin-preferably to the hinge-pin-by lugs 9, `through which the pin passes and which are of larger diameter than the pin, so as to permit some loose or free motion of the lid. The spring 10 may be of usual construction and bears at one end upon the closingarm and at the other end against the face of the lug 3, so that it exerts upon the closingarm a tension pressing it toward the face of the box. When the parts are assembled as above described, the lid will be held against the box by the closing-arm, and as the lid is connected loosely both with the closing-arm and the hinge-pin it can accommodate itself 5o to its seat on the box even when the hingepin vby reason of malformation or warping of the hinge-lugs is not in proper alinement.

The construction is simple and strong, and

the device as a whole is very efficient because 5 5y of the double kconnection of the lid-namely, the loose connection of the body portion of the lid with the closing-arm and its loose connection at the hinge portion-for these two connections not only afford sufcient iexi- 6o bility to the lid to cause it to seat properly, but at the same time they hold it sufficiently well to make it steady and to prevent it from wabbling.

In Figs. 5, 6, 7, and 8Ishowamodication 65 of my invention, in which, instead of connecting the closing-arm to the body of the lid by astud and socket, as above described, the arm may be formed with eyes 7', which engage hooks 8' on thelid, or the eyes may be on the 7o lid and the hooks on the arm. I also illustrate in these ligures a modied loose connection of the lid at its hinge end with the closing-arm. In this case I form lips ll on the margin of the lid, which Iit over the hingelugs of the closing-arm, being bent inwardly for that purpose. This construction aords, though in a different form, the same kind of loose connection as described above with reference to Figs. l and 2.

In order to make the lid dust-proof and otherwise to increase its efticiency, I provide it with a lip .l2 at its upper margin, which tits across the top edge of the box, and I also prefer to form lips 13 along the lateral edges 85` of the lid, which engage the outer edge of the box.l I also form on the inner side of the lid a lip 14., which when the lid is closed overjections "l5, which extend on the lid upwardly from the lip 14 and serve to prevent the oil 95 from spreading sidewise and running out at the corners of the box; and by preference these projections are made angular in form.

The lips and projections named in this para graph may be applied to lids of other construction.

Modiications of my invention will be suggested to those skilled in the art; since Vhat I claim isl. The combination of an axle-box, a lid, and a spring-actuated closing-arm hinged to the box, connected loosely with the body of the lid and adapted to force the same against its seat, said lid being also loosely connected With one of the said parts at the hinge portion; substantially as described.

2. The combination with the lid, of a springactuated closing-arm, and a stud on the arm fitting an open socket on the lid; substantially as described.

3. The combination of an axle-box, a lid, and a spring-actuated closing-arm hinged to the box, connected loosely with the body of the lid and adapted to force the same against its seat, said lid having lugs fitting loosely at the hinge-pin; substantially as described.

4. An axle-box lid have an oil-shedding lip on its inner surface adapted to lie over the edge of the box and having upward projections to prevent spreading of the oil; substantially as described.

5. An axle-box lid having on its inner surface projections adapted to prevent lateral spreading of the oil; substantially as described.

G. An axle-box lid having on its inner surface angular projections adapted to prevent lateral spreading of the oil; substantially as described.

In testimony whereof I have hereunto set my hand.

JOHN W. STEPHENSON.
