CAR-AXLE-BO X CCVER.

SPECIFICATION forming part of Letters Patent No. 334,705, dated January 19, 1886,

i Application filed October 26,1885. Serial No. 180,985. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS HYDE, of Detroit, county of Wayne, State of Michigan, have invented a new and useful Improvement in Car-Journal-Box Covers; and I 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 pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements in covers for carjournal boxes, and is designed to provide such a journalbox with a cover easily operated, which can be readily removed and replaced, if desired, without disconnecting the journal-box, which will be self-closing, from the motion and jolting of the car, should it be left open by the workmen when lubricating the journal, which shall also be close-fitting, so as to exclude dust, and which will not be liable to work loose or rattle either when new or after it has been in long use, all of which objects, together with the general construction and arrangement, are hereinafter more fully described, and more particularly pointed out in the claims. In many devices of this class heretofore constructed it has been impossible to renew or replace the cover without disconnecting the journal-box, as in said devices it is necessary to locate the cover in place before the box is secured to the truck-frame, the frame preventing the removal of the cover, and also the entrance of a cover to its place. My invention is designed to overcome this difficulty.

In use sliding covers for car-journal boxes have been found to be preferable, and my invention is designed'to provide a cover of this class.

I carry out my invention as follows: In the drawings, Figure 1 is avertical section of such a device embodying my invention. Fig. 2 is a front elevation. Fig. 3 is a side elevation with parts broken away. Fig. 4 is aseparate view of the cover.

A represents an ordinary car-journal box, which I provide with guideways ca, grooved, as shown at a ,to permit the cover sliding therein, and also recessed toward their upper extremities, as shown at to permit the cover that position rests in the recesses of said guide- 55 ways, the lower edges of the recess being slanted or rounded, to permit the cover to work readily into and out of said recesses. These guideways may be cast integral with the journal-box. They are also perforated, as shown, to receive a bolt, B, at their upper ends, said bolt provided with a nut or analogous device to hold it in place, and yet to permit of its ready removal.

0 is the frame, to which the journal-box is Secured.

D represents my improved cover, constructed with wedge-shaped flanges d cl at its two sides, said flanges narrowing toward the bottom of the cover,to permit the cover wedging itself into place in the guideways when it is thrown down into its normal position to close the box. The cover itself, moreover, is made wedge-shaped at right angles to said flanges, being made narrower at its lower end,to assist in wedging the cover in place when the boxis to be closed, and which shall at the same time facilitate its ready opening, as it will cease to bind when slightly elevated.

The guideways, as shown, project over the flanges of the cover for the most part, and form a bearing-face for said flanges, and also to prevent the entrance of dust. The cover is also provided with a shoulder or bar, D, toward its lower end, which limits the upward throw of the cover, as said shoulder, when the cover is raised, will strike against the rod B, preventing the displacement of the cover while the rod is in place, said shoulder also being made heavy enough to receive the impact of a hammer for raising the cover, as is ordinarily done, and which. shall give additional weight to the lower end of the cover, to assist in rendering -it self-closing by its own gravity under the jolting motion of the car, should the cover be inadvertently left up by the workmen.

It will be seen that by making the cover to wedge in two ways at right angles to each other a very close fitting cover is provided, and dust is excluded. It is evident that the angle of the covers inclination in the guideways is such that it may be thrown upward and tilted over the journal-box, as shown in Fig. 3, without striking against the frame 0, and it is, moreover, evident that by removing the rod B the cover may be entirely disengaged from the journal-box without the slightest difliculty, and replaced by securing the bolt again in its place in the guideways, and the cover becomes secured in position and cannot be accidentally displaced.

The location and construction of the re cesses (t in the guideways are such that the cover may be elevated and tilted back to permit the ready removal of the brasses and wedge, and for the ready lubrication of the journal. The shoulder or bar D serves to assistin guiding the cover in moving it upward or downwardi. 0., to prevent too great lateral motion. The grooves are inclined toward each other at the base, so as to make the distance apart narrower at the bottom than at the top, to conform to the corresponding wedge shape of the cover. As so constructed, the entire journal-box and cover are practically constructed in but three piecesthe box with the guideway integral therewith, the cover, and the bolt with the nut belonging thereto.

\Vhile I prefer to construct the shell D of sufficient length to prevent too great lateral motion of the cover in its movement in the guideways, I would have it understood that its length is not an essential feature of my invention, its use as a guide being an unessential feature. 7

I am aware that the sliding lid or cover of a car-journal box has been provided with a longitudinal slot to receive a spring pin or bolt by which said lid is coupled to the axle-box or its housing. Iain also aware thatit is notnew to provide an axle-box with grooved flanges to receive a downwardly-tapering sliding lid or cover. A sliding lid has also been provided with tapering end flanges fitting over upon the side faces of the box and carrying ribs adapted to fit and slide in vertical grooves formed in the side faces of the box, stops being provided for preventing the lid'from being entirely withdrawn from its engagement with said slots. Such construction, however, I do not claim.

\Vhat I claim is l. The combination, with a ear-journal box provided with grooved and recessed guideways, and a removable bolt passed through the upper ends of said guideways, of a wedgeshaped cover having wedge shaped side flanges, and provided at its lower end with a transverse retaining-bar, substantially as described.

2. The combination, with a ear-journal box having guideways provided with tapering grooves a and recessed upper ends, a, of a wedge-shaped cover provided at its lower end with a retaining-bar, D, and having wedgeshaped side flanges,d d, and a removable bolt, B, secured in the upper ends of the guideways, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

FRANCIS HYDE.
