CAR-AXLE-BOX LID.

SPECIFICATION forming' part of Letters Patent No. 566,047, dated August 18, 1896. Application filed October 22,1895. Serial No. 566,573. (No model.)

To a/ZZ whom it may concern:

Be it known that we, HENRY C. W'ILLIAM- SON, residing at MichiganL City, La Porte county, State of Indiana, and CHARLES A. SCHROYER, residing at Chicago, in the county of Cook and State of Illinois, citizens of the United States, have invented certain new and fuseful Improvements in Car-AxlesBox Lids; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a novel construction in a car-axle-box lid, the object being to provide an improved and more efficient device of this construction.

The invention consists in the features of construction and combinations of parts hereinafter fully described and specifically claimed.

In the accompanying drawings, illustrating our invention, Figure l is a vertical section of the car-axle box and lid constructed in accordance with our invention and with the lid closed. Fig. 2 is a similar view with the lid' open. Fig.- 3 is a cross-section taken on the line 3 3 of Fig. l. Fig. 4 is a vertical section of a car-axle-box lid constructed in accordance with our invention and showing the lid closed, and also illustrating the `manner in which the pocket 5 can be located in a differof this kind, and to hold the spring to the lid,

as well as to permit its ready insertion, various constructions have been proposed possessing to a certain degree objectionable characteristics, which it is the object of this in vention to overcome.

In accordance with the principle involved by our invention we construct the car-axle boxl in the usual mannerthat is to say, provided with the shoulder or vprojection 2, to

which the lid is pivoted. The lid 3 is construoted in the usual manner, except so far as my invention applies to it, and is pivoted to the shoulder or projection 2 of the car-axle box. The plate-spring 4 is employed to hold the lid 3 firmly against the box l, or to hold it in an elevated position, as shown in Fig. 2, and to secure this spring 4 to the lid and to permit its insertion we employ a pocket 5, which is situated on the inner face of the lid. This pocket 5 is preferably cast integral with the 4lid and is wider at its lower end, in a direction perpendicular to the plane of the lid, than at its upper end and is transversely of a width to receive the plate-spring. Said pocket 5 is provided with a shoulder 6 on the lower end of the inner face of the inner wall thereof, against which the end of the spring abuts. Between this shoulder 6 and the lid is a slot or opening-7, through which the spring can pass. Adjacent to the pocket 5 and on the inner face of the lid 3 are'two lugs or guides 8, between which the spring is situated, and which serve to hold thespring against lateral displacement.

It will be noted that the pocket or recess in the lid adapted to receive the lug or projection 2 begins where the guides S are situated, thus forming a bend 9 in the lid at this point, which is adapted to act as a fulcrum over which the spring is bent. As the tendency of the spring is to assume its original. straight form, the said fulcrum will direct its resiliency so as to hold one end of the same in engagement with the inner face Vof the vinner wall of said pocket 5 and thus prevent said end of said spring from passing over said shoulder 6.'

In use, after the lid 3 has been pivoted to the projection 2 it is raised to the position shown in Fig. 2. Then the plate-spring 4 is inserted through the slot 7 of the pocket 5, as

shown in dotted lines in said Fig. 2, and is driven inwardly until its inner end `strikes the upper face of the projection 2. Then by further driving the spring the outer end thereof passes over the said upper face of the projection 2, the middle portion at this time coming in contact with said fulcrum 9, over which it is bent during its passage, to a posi- IOO tion shown in full lines in said Fig. 2., and when it reaches this position the outer end of this spring will have just passed the edge of the shoulder 6 and by its resiliency will spring past the shoulder, so that it will be held irmly in position. When the spring is thus driven and the lid is in this position, the spring exerts a force to hold the lid in the elevated position; but when the lid is thrown downwardly to close the box, as shown in Fig. l, the spring will then exert a tendency to hold the lid closed against the open end of the box, as will be plainly obvious. It will be obvious that the spring may also be inserted in said pocket 5 before the iid is pivoted tothe projection 2 and the spring compressed by placing its free end against said projection 2 and pressing the lid inwardly until the pivotopenin gs therein are iiush with the pivotopening in said projection 2.

It will be seen from the foregoing description that this lid can be cast and that there are no openings through the lid, as is usual in lids now commonly used, and that while the spring serves to hold the lid in the desired positions it does not project through the lid, and consequently no openings are made through which dust and dirt can enter the caraxle box. It will be seen, further, that a special forni of spring is unnecessary, it being sufiicient to employ a straight plate-spring of a length to reach from the pocket 5 on the lid, as shown in Fig. l, over said projection 2 to a point adjacent the end wall of the pocket or recess adapted to receive said projection 2. It will be further noted that should the spring break or become useless it will never leave an opening in the lid through which dirt and dust can enter, and, further, the spring can be readily replaced without removing the lid from the boX.

We claim as our inventionl. A caraxle-box lid provided on its inner face with an inwardly-extending pocket having openings between the inner wall thereof and the inner face of the lid, a shoulder on the lower end of the inner face of the inner wall of said pocket, and a spring having one end situated within said pocket and adapted to abut against said shoulder.

2. A car-axle-box lid provided with an in wardly-extending pocket upon its inner face and at its lower end, an opening atn the upper end of said pocket, a shoulder on the lower end of the inner face of the inner wall of said pocket, an opening between said shoulder and the inner face of said lid, and a spring having one end situated within said pocket and adapted to abut against said shoulder.

3. The combination with a car-axle box provided with a shoulder 2, of a lid pivoted thereto, va pocket on the inner face of said lid, an opening in the upper end of said pocket, a shoulder on the lower end of the inner face of the inner wall of said pocket, an opening.

between said shoulder and the inner iace of said lid, a fulerum on said lid, and. a platespring having one end. situated within said pocket and adapted to abut against said shoulder and bearing against said fulcruin and said projection 2.

4. A car-axlebox lid provided with an inwardly-extendin g pocket on its inner face and adjacent to its lower end portion, an opening at the upper end of said pocket, a shoulder on the lower end of the inner face of the inner wall of said pocket, an opening between said shoulder and the inner face of said lid, a fulcrum on said lid, guide-lugs adjacent said fulcrum, and a spring having one end situated within said pocket and adapted to' abut against said shoulder, said spring passing over said fulcrum and between said guidelugs.

In testimony whereof we affix our signatures in presence of two witnesses.
