11 Claims.

This invention relates to journal boxes and, more particularly, to articulated or two piece lids normally closing the outer openings of said boxes.

The principal object of -my invention, generally considered, is to provide a two piece equalizing lid for closing the journal box opening, said lid preferablyinvolving a'hood or spring housing and a lid proper between which a torsion spring is positioned, said spring having a pair of coils normally seated on the hood, an intermediate loopnormally engaging the hinge lug and depending ends engaging means connecting said lid proper and housing.

Another object of my invention is to provide a two piece lid rin which the actuating spring is positioned between the hood and lid proper with the coils'ofY the spring seated on the hood and theV free ends received in a casting pivoted to a lug on the face of the lid, which casting preferably has its ends receivedin pockets in the lower end of sai-d hood, whereby spring tension is maintained between the elements of the lid assembly.

A further object of my invention is to provide a journal box lid having a hood pivoted thereto adjacent its center for enclosing an associated torsion spring, said spring having coils seated on the hood and extending into depressions inl the face of the lid, an intermediate loop portion being adapted to engage the hinge lug on an asso-- ciated box for holding the lid inY open or closed position, said loop portion being preferably provided with a wear plate or the like formed with outstanding loop portions, and a pin or rivet on the hood passing through said loop portions for` limiting relative movement between said spring and hood.

Other objects and advantages of the invention relating to the particular arrangement and construction ofthe various parts will become apparent as the description proceeds.

Referring to the drawing illustrating my invention, the scope whereof is dei-ined by the appended claims.

Figure 1 is a front elevation of a journal box lid assembly embodying my invention, a portion of the hood or spring housing thereof being broken away to more clearly show the construction.

Figure 2 is a sectional view of the lid assembly and a fragmentary portion of the associated journal boxon the line 2 2 of Figure 1, looking in the direction of the arrows.

Figure 3 is a fragmentary sectional view on the line 3-3 of Figure l, lookingin thedirectionof the.arrows.- f

Figure 4 is a fragmentary sectional view on the line 4-4 of Figure 1, looking in the direction of l the arrows.

Figure 5 is a fragmentary side elevationall View of the upper end of the hood or spring housing showing the bifurcated end of the pin which serves to mount the lid assembly on the box.

Referring to the drawing in detail, likeA parts being designated by like reference characters, a` portion of a journal box l is shown with an ordi-4 nary form of hinge lug 2 extending from the upper wall or roof thereof to which the journall box li-d assembly 3 is pivotally connected as by means of a hinge pin or pintle 4. In the present: embodiment the complete journal boxlid assembly 3 comprises a closure member or lid proper 5, a hood or spring housing member 6, withy con--V necting or equalizing means 7, which equalizing means is preferably pivotally mounted on a 4lug 8 outstanding from the front face of the closure 755 member 5 and desirably received in a pocket Qin the equalizing member 7, said member being movably` or adjustably mounted with respect to the lid or closure member 5 by a pin or rivet 10` passing through said equalizing member '7 and so lug or flange 8. The lower portion or ends l1 of, the hood 6 are desirably formed with pockets or sockets 12 receiving the ends or trunnion portions 13 on the connecting and equalizing casting 7, whereby said hood 6 is adjustably held in assembled relation with respect to the lid 5.

The lid assembly 3 is desirably pivoted to the box'l by means of the pivot pin 4 extending through perforated ears or hinge portions 14011 the hood 6 rather than through corresponding portions on the lid proper. The hinge pin i may be held in locked position in any desired manner as by having the end split or bifurcated and expanded in placein a well known manner. The corresponding lug or bearing portion 14 receiving the expanded end may have the aperture elongated for properly receiving the separated prongs 15 on the pin, whereby when locked in place, turning of the pin with respect to the hood is prevented.

Inorder to provide for resiliently holding the lid in open or closed position, a torsion spring 16 is desirably positioned between the hood 6 and lid proper 5. The spring 16 preferably has a pair of coils or helical portions 17 normally resting on curved seat portions 18 on the housing or hood and an intermediate loop or upwardly extending portion 19 desirably formed with a wear plate 20 or anti-friction device such as a roller (not shown) for engagement with the hinge lug 2 in a normal 11,0

manner. The free ends or depending tails 21 of the spring are desirably received in corresponding pockets or apertures 22 in the connecting casting 7, said apertures being desirably disposed adjacent the ends of the casting 7 or trunnion portions 13 thereon. To avoid the necessity of positioning the hood 6 at too great a distance from the lid 5, that portion of the lid adjacent the coils 17 is preferably normally depressed or pocketed, as indicated at 23, to receive the adjacent portions of said coils. For rigidifying the construction, the lid may be formed with an inwardly extending flange 24 and provided with the usual peripheral flange 25.

In order to limit relative movement between the spring and hood, particularly when the lid assembly is disconnected from the box, the wear plate 20 is desirably formed with outstanding strap or loop portions 26 and the hood 6 preferably has a rivet or pin 27 passing through said loop portions 26 with the desired clearance therebetween for permitting all necessary or desirable movement of the spring while preventing an excessive movement thereof, especially when the lid is removed from the box.

From the foregoing disclosure, it will be seen that I have provided a two piece, resiliently pressed, self-adjusting or equalizing lid for a journal box, said lid involving a closure portion, a hood or spring housing portion and a connecting or equalizing portion, a torsion spring being preferably received between the hood and closure portion of the lid assembly. On account of the tails of the spring being received in the connecting or equalizing member, and the equalizing member being pivoted on the front face of the lid proper, and the hood and equalizing member being interlocked, all parts of the lid assembly are held in proper relation one with another, while at the vsame time, a limited amount of necessary equalizing movement of the lid proper or closure member is permitted, whereby a substantially equal pressure between the lid and the box is maintained around the entire periphery thereof. On account of the upper or looped end of the spring carrying a loop or retainer interlocked with the hood, the spring is prevented from being displaced with respect to said hood even when the lid is removed from the box, whereby the lid assembly may be shipped as a unit.

Although I have disclosed a preferred embodiment of my invention, it will be understood that the same is merely illustrative and that modications may be made within the spirit and scope of my invention as set forth in the appended claims.
