8 Claims.

This invention relates to journal boxes and, more particularly, to lids therefor and means for pivotally mounting said lids on said boxes.

The principal object of my invention, generally considered, is to provide a three-piece lid allowing free equalization with respect to an associated box, said lid involving a closure member, a loop member movably connected to the central portion of said closure member and carrying hinging ears or scrolls, and a spring retainer, tensioning member or stirrup adapted to engage the intermediate or coil portions of a torsion spring for holding the spring in stressed position in engagement with the hinge lug of an associated box.

Another object of my invention is to provide a preferably pressed steel journal box lid which is adapted to be so equalized with respect to an associated box that the edge thereof engages the outer opening in said box around the full periphery thereof to securely close said openmg.

A further object of my invention is the provision of a journal box lid comprising a closure member, a loop member carrying scrolls or hinging ears and flexibly attached to said closure member, a torsion spring with the lower ends attached to said closure member preferably by the same means which connect the loop member to the closure member, and means for stressing said spring so that it acts to hold the lid in open or closed position with respect to an associated box.

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

Referring to the drawing illustrating my invention, the scope whereof is defined by the appended claims:

Figure 1 is a front elevation of one embodiment of my journal box lid.

Figure 2 is a transverse sectional view on the line 2-2 of Figure 1, looking in the direction of the arrows.

Figure 3 is a side elevation of the loop or hinging member for the lid.

Figure 4 is a fragmentary sectional view on the line 44 of Figure 1, looking in the direction of the arrows.

Referring to the drawing in detail, like parts being designated by like reference characters, I have shown the invention in connection with a pressed metal lid mounted on a standard journal box, although it will be understood that I overlying the ends of the pin 11.

do not wish to be limited to this showing. The lid assembly 1 comprises a closure member or lid proper 2 and a loop or generally U-shaped connecting member 3 flexibly attached to the outer face of the lid proper 2 by means of a strap or retainer plate 4 and rivets or other connecting means 5. The outer face of the lid proper or closure member 2 is desirably inwardly embossed or depressed, as indicated at 6, to receive a corresponding portion 7 on the loop member 3 to provide for a limited amount of swivelling or equalizing therebetween, the neces sary clearance for that purpose being provided between the connecting member 4 and the outer face of the loop member 3.

The loop or U-shaped member 3 has upwardly extending arms 8 and is desirably of pressed metal to correspond with the construction of the closure member, longitudinal corrugations 9 being desirably formed for stiffening purposes. The upper ends of the arms 8 are provided with hinging ears or scrolls 10 which may closely embrace or be mounted on the pivot pin or pintle 11, which thereby serves for connecting the lid assembly to the box 12 as by passing through a corresponding aperture 13 in a hinge lug 14 on the roof of said box. In order to retain the pivot pin in place, the loop member 3 maybe provided with bendable tabs 15 adapted to be moved to locking position The hinging ears or loops 10 may be made circular to closely fit the hinge pin 11, because with the loop member 3 articulated or flexibly connected to the lid, it is unnecessary to provide for equalizing between the scrolls or hinging ears 10 and the hinge pin 11.

The lid assembly 1 is provided with a preferably torsion spring 16 for holding it in open or closed position with respect to the box 12. The spring 16 is shown with intermediate coil portions 17 and depending end portions 18, which end portions preferably have their extreme lower ends turned toward one another, as indicated at 19, and underlying the plate or retaining strap 4, so that said retaining member serves for holding the lower ends of the spring as well as the loop member in position with respect to the closure member 2; The in-turned portions 19 of the spring desirably seat in the corresponding corrugations or depressions 29 in the loop member. The upper portion of the spring 16 comprises a loop 21 which may engage the hinge lug 14 or carry an anti-friction device or roller 22 thereon, which normally engages the hinge lug for holding said lid in open or closed position, in a manner which will be understood.

For placing the spring 16 under the desired tension, so as to make it operative for the purpose, a retainer, tensioning member or stirrup 23 is provided, and comprises a plate or retainer portion 24 desirably shaped to fit the outer portion of the spring coils 1'1 and formed with upwardly extending apertured arms 25 receiving and being supported by the hinge pin 11. The retainer be ing mounted on the pin 11 independently of the lid proper or hinging loop for said lid proper, may be forced into operative position over the coils l? of the spring when the lid is in closed position, so that the spring will exert its pressure at the center of the lid in such a manner that the lid will seat itself evenly on the top, bottom and sides of the box face even though the relation of the hin e pin to said lid is not entirely accurate, the necessary equalizing moved out being provided by the flexible mounting between the loop member 3 and lid 2, and the natural resiliency in the arms 3 of said loop member.

From the foregoing, it will be seen that I have devised a lid which is so flexibly mounted on an associated journal box that it is adapted to equalize when pressed into engagement with the periphery of the journal box around the front opening therein to thereby seat securely with respect to said box.

Although I have shown a lid of pressed construction and formed with stiffening corrugations 26 and a peripheral flange 27, it will be understood that thelid proper, as well as the other parts, if desired, be formed in other ways than by pressing sheet metal and that I may, if desired, make my lid and the associated parts as castings.

Although I have disclosed a preferred embodiment of my invention, it will be understood that modifications may be made within the spirit and scope of the appended claims.
