To all whom 'it may concern:

Be it known that I, RICHARD D. SMITH, a citizen of the United States, residing at Bristol city, in the county of lashington and State of Virginia, have invented a newl and useful Box-Lid Fastener, of which the following is a specification. j

This invention has for its object to provide a simple and efficient locking device fol securing the lids of journal boxes, in order to prevent tampering with, or the unauthorized removal from the box, of the packing or brasses.

The invention made in the wall of the box on the inside thereof, adjacent to the lower end of the opening over which the lid fits. In the other end of the stud, on the outside of the lid, is an annular groove 15 which is enby the branches 9 of the forked end of the spring 7. In this end of the stud is also made a socket 16 adapted to receive a key 17 for turning the stud, to engage and thereof. This key may as shown, the socket being shaped accordingly. If desired any other form of key may be provided.

Over the socket is placed a guard coinprising a metal strip 18 which is riveted or otherwise secured to the face of the lid, one

also has for its object to provide a locking device which can be readily applied to any standard hinged journal box lid, no alteration or modification in the structure thereof being necessary.

With these objects in view, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the drawings hereto annexed, in which,

Figure 1 is a vertical section view of one form of journal box, its lid, and the locking device. Fig'. 2 is a front elevation of the lid. Fig. 3 is a perspective view o-f the key. Fig. 4 is an enlarged section on the line 4`4 of Fig. 1. Fig. 5 is a vertical sectional view of a journal box, its lid and a modified form of locking device. Fig. 6 is a front elevation of the lid shown in the last ligure. Fig. 7 is an enlarged section on the line 7`7 of Fig. 5.

In Figs. l and 2 of the drawings, 5 denotes a journal box, and 6 is the hinged lid thereof, said lid being fitted with the usual spring 7 for holding it in place. In the present instance, this spring is made somewhat longer than usual, and is rigidly secured intermediate its ends by a rivet 0r the same, and has an aperture 19 correto the stud socket, to inserted thereinto, and

is locked.

The lid is locked and unlocked by inserting the key into the socket, and turning the stud. In locked position the rib 13 seats in the groove 14, whereby the lid is securely locked. The spring' 7 binds the shoulder 11 against the inner face of the lid, and retains the rib 13 in the groove 14, and thus prevents accidental turning of the stud, so that it will not be jarred into unlocked position. After locking the lid, the key is removed The lock herein described effectually serves the purpose for which it is designed and the box is made dust-proof by locking it. The lock is simple in structure, and it can be readily applied to any standard hinged lid, no change or modification in the structure of the lid be other fastening means 8. The lid has a hole, In Figs. 5 to 7 a slightly modified form as usual, through which one end of the of lock is shown, the journal box bein@ indispring passes into the journal box, the other cated at 20, and the lid at 21. The lid spring end of the spring being located on the outside of the lid, and extending down to a point adjacent to its lower or free edge. This end of the spring is notched to form a fork, the branches of which are indicated at 9.

Adjacent at its lower or free end, the lid ias an opening in which is mounted a rotatable stud 10 having at one end a shoulder 11 adapted to engage the inner surface of the lid, and a wing 12 having on one side, a rib 18 adapted to be seated in a groove 14 22 is secured to the under side of the lid, and does not pass through a hole therein as in the construction rst described, and also is not elongated, but is of the usual length. As in the first instance, the lid carries at its lower or free end a rotatable st-ud 23 mounted in an opening in the lid. The stud has a shoulder 24 at one end adapted to engage the inner surface of the lid, and a wing 25 having on one side a rib adapted to be seated in a groove made' in the wall of the box on the inside thereof, adjacent the lower end 0f 7"? termediate its ends,

ing a key responding in shape the stud having akey socket, a wing on the stud engageable with the wall of the box on the inside thereof, and a spring engageable with the stud for binding the aforesaid shoulder against the inner face of the lid, and retaining the stud in locking position.

3. The combination with a journal box lid, of a shouldered rotatable stud carried thereby, said stud having a key socket in its outer end, and an annular groove, a wing on the inner end of the stud engageable with the wall of the box on the inside thereof, and a spring having a forked end, the branches of the fork entering the groove of the stud, for binding the shoulder of the stud against the inner face of the lid, and retaining the stud in locking position.

4. The combination with a journal box lid, of a shouldered rotatable stud carried thereby, said stud having a key socket in its outer end, and an annular groove, a wing on the inner end of the stud enga geable with the wall of the box on the inside thereof, and a guard strip fitting over the socketed end of the stud, said strip having an aperture corresponding in shape to that of the key socket, the strip being secured to the lid, and bowed outwardly therefrom to clear the socketed end of the stud, one end of the strip being folded, and terminating in a spring tongue located under the bowed portion of the strip, and having a forked end, the branches of the fork entering the groove of the stud, for binding the shoulder thereof against the inner face of the lid, and retaining the stud in locking position.

In testimony that I claim the foregoing as my own, I have hereto alixed my signature in the presence of two witnesses.

the opening over which the lid fits. In the other end of the stud, on the outside of the lid, is an annular groove 26 which is entered by the branches of the forked end of a spring tongue 27. lIn this end of the stud is also made a socket 28 adapted to receive a key for turning the stud, to engage and disengage the wing thereof. The spring tongue 27 is formed integral with a guard strip 29 extending in a curve across the socketed end of the stud. The guard is a spring metal strip which is riveted or otherwise secured at one end to the lid, and is folded at the other end, as indicated at 30. The folded portion is riveted or otherwise secured to the lid, so as to leave a free portion which forms the spring tongue. Inthe strip is bowed outwardly from the socketed end of the stud to clear the same, and has an aperture corresponding in shape to the socket, to permit the key to be inserted thereinto, and removed after the lid is locked.

The operation of the lock last described is the same as the one shown in Figs. l to et, the spring tongue 27 having the saine function as the spring 7. This form of lock can alsoV be applied to a lid having no spring.

What is claimed is:

1. The combination with a journal box lid, of a rotatable stud carried thereby, and havsocket in its outer end, a wing on the inner end of the stud engageable with the wall of the box on the inside thereof, and a guard strip over the socketed end of the stud, said strip having an aperture corto that of the key socket.

2. The combination with a ournal box lid, of a rotatable stud carried thereby, said stud having a shoulder engageable with the inner face of the lid, and the outer end of IlVitnesses N. C. GALLIHER, JAS. II. LEONARD.
