N-.- Y.,.a corporation of Maryland pplication February 18, 1`9481,Serial No. 9,229 Glaims. (Cl. 30S- 47) l This 'invention relates 'tof'a journal .b'ox lid' for use in. a vrailway truck.;

An object of the invention is the provision 'of a bridge. member which vmay be 'rmly and securely interlocked. with a cover` ofv a :leur-nal.

box lid.

Another object of the invention is: the provision of a journal box lid whichr has .a bridge member thereof clamped to a cover so as' to v'avoidv the necessity of additional holding means.

'I'.hese andA .many other objects of. the present invention will become 'appa-rent from. the succeed.- ing description considered together with the accompaI-iyingv drawing wherein:

Figure 1 is a front elevational View of a journal box lid embodying the present invention.

Figure 2 isA a cross sectional View taken along the lines 2 2 of Figure 1, looking inthe direction of the arrows.

Figure 3 is a side elevational View of a part of the journal box lid.-

Figure 4.- is a partial end elevational view and partial sectionalview of. the' part shownv in Figure 3.

Referring now in detail tothe drawing, wherein like reference characters indicate like parts, the numeral I is employed to designate; in a somewhat general manner, a journal box lid exemplary of the present invention. Journal box lids of the type of the present invention are employed as a movable means for normally closing an access opening into a journal box (not shown) to exclude water, dirt or any foreign substance from the interior of the journal box. Illustrative of the present invention is a hood 2 having at its top portion, ears 3 through which extend a pin or pintle (not shown) to connect pivotally the lid to the journal box. The hood has, adjacent a lower extremity thereof, a ballshaped member 4 which, as will be hereinafter pointed out, aiTords a universal movement of another part of the lid.

Associated with the hood is a cover 5 which will, when in closed position, completely mask or blanket an access opening (not shown) of the journal box to effectively block out the entrance of any foreign substance to the interior of the journal box. As clearly indicated in Figure 2 only of the drawing the cover has adjacent its central portion a socket-like cavity 6 which removes the adjacent portion of the cover from contact with the hood and thus an unrestricted movement of the cover is alforded relative to the hood. A spring, which may be of any type, is disposed within the connes of the hood and, for

the. .purpose of illustration, there. is shown. a

spring 'I having central coils 8 seated against'the: hood with an upwardly directed portion 9 areA ranged to bear against a part of the journalF box. The spring also has depending members l0 extending downwardly from the `coils to bear'.

directly against the cover in the area of cavity 6 (see Figure 2) to` 'urge thereby the cover' lirmly' against the journal box when the lid is in` closed: position.

A means must. be associated wththe hood and cover in order to maintain the two in*A assembled relation. As illustrative of such a means there is provided a bridge. or 'clip' member I I foi-med preferably as a pressing of steel. The bridge member is in the natureV of a strip having a mai-n body portion 'I2 spa-ceda predetermined distance loutwai-'dlypf or away from a face I3 of the cover. Intermedi-ate the ends Aof the 'mai-n body portion isv -av protuberance'or indentation I4 spherical in configuration and' arrangedr to nest in' or be cuppedby the ball-shaped lower extremity 4 of the hood. By this association of universal joint parts the cover will definitely fully bear against the jour-nal box.

The cover; above and below the cavity 6 thereof. is provided with slots or openings IS-Which extend horizontally and are of a height to correspond to the thickness of the metal used in forming the bridge member. Extending vertically from the slots are slits I6 cut in or completely through the cover to form lips I1. These lips are initially displaced or urged outwardly of the cover to enlarge the clear opening I5 through the cover. This initial displacement is indicated in Figure 2 only of the drawing by the reference character I6a. The main body portion of the bridge member has extending therefrom vertically spaced legs I8 which extend through the openings I5 where they terminate in reentrant flanges I 9. The reentrant flanges are disposed normal or substantially so to the related or associated legs and thus, when in position or assembled with the cover and hood, the flanges rest or are disposed behind the cover to thereby lock the bridge member to the cover. Shoulders 20 are formed on the legs of the bridge member and these shoulders are arranged to bear against the face of the cover to thus have the cover rmly gripped between the shoulders and reentrant flanges.

In order to facilitate the assembly of the bridge member and cover, the legs of the bridge member are initially formed in a spreading fashion so as to extend away from one another-see Figure 3 and the diagrammatic lines I8a in Figure 2. By this spreading of the legs assembly is made much easier. In order to assemble the parts, the cover is set upon a die (not shown). The spring and hood are then placed in position and the bridge member is mounted upon the hood with the legs and their reentrant anges extending through the enlarged openings in the cover. Another die (not shown) is brought to bear upon the bridge and during the closing movements of the dies the legs of the bridge member are urged to the position illustrated in Figure 2 as substantially normal to the main body portion thereby urging the flanges behind the cover and finally the lips la are pushed back into position to be in the plane of the main part of the cover to additionally bind the bridge member in place.

From the above it will vkbe noted that various changes and alterations` may be made to the illustrated and described construction Without departing from the spirit'of the invention and scope of the appended claims.

I claim:

1. In a journal box lid of the type having a hood universally mounted on a cover, the com.. bination of, vertically spaced slots in said cover adjacent a central portion thereof, a bridge member embracing a part of said hood, said bridge member having angularly directed legs extending through said slots and terminal flanges on said legs locking said bridge member to said cover.

2. In a journal box lid of the type having a hood universally mounted on a cover, the combination of, spaced slots in said cover adjacent a central portion thereof, a bridge member having a ball portion arranged to be cupped in a socket of said hood and spaced from said cover, legs on said bridge member extending through said slots, and reentrant flanges on said legs disposed in back of said cover for locking said bridge member to said cover.

3. In a journal box lid of the type having a hood universally mounted on a cover, the combination of, portions of said cover being initially displaced to form enlarged openings in said cover, a bridge member having a ball-shaped portion spaced from said cover and nesting with a corresponding portion of said hood, legs on said bridge member extending through said enlarged openings, and terminal flanges on said legs for locking said bridge member to said cover; said displaced portions being arranged to be urged back to the main plane of the cover after assembly of said bridge and cover to bind said bridge member in place.

4. In a journal box lid of the type having a hood universally mounted on a cover, the combination of, integral displaced portions adjacent a center of said cover to present openings therein, a bridge member having a ball-shaped portion spaced outwardly from said cover and nesting With a part of said hood, legs on said bridge extending through said ,openings in said cover, and iianges at ends of said legs interlocking said bridge member and cover; said displaced portion of said cover being arranged to be urged back to their original position to bind said bridge member in position.

5. In a journal box lid of the type having a hood and a cover, a bridge member comprising a body portion having an outwardly opening ball-shaped protuberance intermediate its ends, spaced legs extending substantially normal to said body portion, and a ange at an end of each of said legs and disposed substantially parallel to said body portion, said flanges being adapted to be secured to said cover for connecting said hood to said cover.
