Various means have been devised for ,r r.

siliently, maintaining closedthe lids ofi journal boxes, the same, means, usually, being .em.-%

ployed to resiliently hold the lids in open position. Both coil springs and leaf springs have been used for this purpose and both have their advantages. Sometimes one is preferred and sometimes the other. A coil spring is usually considered-more desirable,

but it is more expensive and when it becomesbroken it is difiicult to replace immediately, Whereas a leaf spring can usually be found with less trouble. It is therefore the object of my invention toprovide a universal lid which may be employed with either typeof spring. I

In the accompanying drawings in which I have shown a selected embodiment'of my inven'tion;

Fig. l is an end elevation of a journal boxhaving my improved lid applied thereto.

2, but showing my invention. as employed with'a coil spring. g r Referring now to the drawings the nu meral 1 designates a journal box ofany suitagainst the surface 6 to able construction and having hinge lugs 2 within which is received the hinge pin 3 The hinge lugs are made in the form shown having two relative flat surfaces 5 and 6 at a substantial angle to each other and secured upon the bearing 7 onthe face of the lid is a leaf spring 8 adapted to bear against the surface 5 to resiliently hold the lid closed or resiliently hold the lid open. I a

I further provide my lid 4 with a hood, 9 covering and protecting the hinge lugs and hinge pin andprovided on its interior with a lug 10 to receive one end of a coil spring 11, as shown in Fig. 3. The other end of the spring is received within a shoe 12 having a surface normally contacting with the fiat surface 5, as shown in full lines in Fig. 3, and also adapted to contact with the flat surface 6, as shown in dotted lines in the same figure. This shoe is preferably pro- .vided with the recess 12 forming a grease cup to receive grease, in order to. provide proper lubrication between the shoe'and the surfaces 5 and ,6. u

The springland shoe shown in Fig. 3, as well as the hinge lug, is standard. equipment,

but the standardilid employing this type of spring and shoe has no -means for replacing the same without taking the lid completely off the journal box, the spring being usually completely enclosedin the. hood. .I therefore provide the hood of my invention with the opening 13 whereby when desired the leaf spring 8 may be put in place instead of the coil spring. .This is absolutely impossible with the standard'hood now employed.

as Y

All that is necessary to install the leaf spring in case of breakage ofthe coilspring, is to drill a hole for the reception" of the rivet 44,

. by means of which the spring can'be secured in .position,as shown in Fig. 2.

On the other hand when tl e leafspring is. v

preferred it may beffurnished' with the lid instead of the coil spring, the installation being made atthe factory. When the leaf {springis initially'provided with the lid,it is obvious that its presence willmake it difli cult to place'the lid in position on the hinge" pin. 1 therefore provide an a perture 15 in one or both-of the side walls of the hood and so placed that a nail, or the like can be inserted therein and will .hold the leaf spring back in the position shown in dotted lines in Fig.2. Then the lid may be readily applied to the" journal box and after this is done the nail or the like, may be withdrawn, 1 if permitting the spring to take the operative position, shown in Fig. 2. I a

From the above it will be obvious that I have provided a'universal journal box lid whichmay be readily used with either type of spring, the change from one type to. the

other being very readily effected. All that is necessary tof replace a coil spring-with a leaf springis to drill a hole for the rivet 14 and a leaf spring may usually be improvised without a. great deal of trouble.

I I am aware that changes in the'form, construction and arrangement of parts may be Again the lid can be readily employed for either type of spring, when the springis' to be loo such changes as fairly fall within the scope of the following claims.

Iclaim: V r 1. As a. new article of manufacture, a journal box lid comprising a body provided upon.

its outer side witha follower-housing projecting above the top of the body of theflid,v

the inner side of the housing above the top of the lid being open, the outer face of the lid being provided wit-h a raised leaf spring seat at the open bottom end of the housing,

the bottom of the housing being open to receive a leaf spring upwardly therethrough,;

and opposite side walls of the housinghaving aligned perforations to' receive a rod for the purpose described.

2. A journal box having an upstanding the lug on the box, a coil spring bearing at one end against the back ofthe housing and at its/other end against the rear of the follower to yieldingly hold the follower against the lug, the outer face of the lid being pro Vided with a raised leaf spring seat below and adjacent the bottom of the housing, the bottom of the housing being open to receive awleaf spring thrust upwardly therethrough,

andopposite side walls of-the-hoiusing hawing aligned perforationsfor the purpose de scribed. I f j 4, GEORGE AJVOODMAN.
