LOCK-LATCH.

Specification of Letters Patent.

Patented Got. 23, 1917.

Application filed February 13, 1917. Serial No. 148,352.

To all whom it may. concern Be it known that I, Enosmr Paoon'r'rn, a citizen of the United States, residing at l-lolyoke, in thecounty of Hampden and State of Massachusetts, have invented new and useful Improvements in Lock-Latches, of which the following is a specification.

This invention relates to lock latches.

The object of the present invention is to provide asimple inexpensive latch for the attachment to sidewall: receptacles and the like, for the purpose of preventing the un authorized raising, of the lid or closure of the said receptacle and the removal of the contents.

Another object of the invention is the pro vision of a latch of the above description which is adapted to be placed on the bottom of a receptacle so as to be out of the sight of persons unfamiliar with the same and to be locked in a manner to prevent its operation, the locking means consisting of a pin inserted through the latch and the attaching plate in a manner to permit of its ready insertion and removal.

With these and other objects in view the invention consists of an attaching plate pro vided with a slot and a plurality of openings intersecting the said slot, a spring controlled latch member mounted in the slot upon a pivot provided in one of the intersecting openings, a pin adapted to be inserted in the other opening and passed through an opening formed inthe latch member for locking the same against independent movement and a spring keeper arm adapted to be swung into the path of the said latch member, said keeper arm being provided with a notch for engagement with a hook formed on the end of the latch member.

In the drawings;

Figure 1 is a sectional view of the receptacle having the. invention applied thereto;

Fig. 2 is an enlarged detailed sectional view on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged perspective view of the latch removed from the receptacle;

Fig. 4 is a detailed perspective view of the latch member;

Fig. 5 is a similar view of the keeper arm; and

Fig. 6 is a view of the locking pin.

Referring in detail to the drawings, the receptacle to which the invention is shown applied is indicated at A. This receptacle is in the form of a show case such as is commonly sed by streetlvenders or the like for the inspection of their goods. It includes the hinged closure B, which is of framed glass and the bottom (3, which is usually solid. The receptacle is adapted to be placed upon a suitable support D, the forward edge of the same projecting slightly over the receptacle so as not to interfere with the latch.

-The latch comprises an attaching plate 10 which is adapted to be secured to the underside of the receptacles by means of screws or other fastening devices 11. This plate is provided with a slot 12 and with openings 13 and 14, which intersect said slot. These openings extend entirely across the plate and the opening 13 is adapted to receive a pivot pin 15 by means of which the latch member 16 is pivoted Within the slot 12, the said member being provided with an opening 17 for this purpose. In addition to the opening 17 the latch member is provided with an opening 18 which is adapted to be brought into register with the opening 14, for the passage of a locking pin 19, by means of which the latch member 16 is locked against movement upon this pivot. The attaching plate 10 is provided with a pin 20 and connected with this pin at one end, and to the latch member 16 at the other end, is a coiled spring 21, by means of which the said latch member is controlled.

Secured to the bottom edge of the hinged closure 18 is a spring keeper arm 22, this keeper arm being secured to the closure by means of a pin23, this pin also being employed to secure a finger piece 24 to the out side of the closure for the purpose of operating the same. The free end of the spring keeper arm 22 is formed with a notch 25 and with a beveled portion 26. When the closure 1) is swung into a closed position the beveled portion 26 of the arm 22 will engage the beveled notched portion 27 formed in the latch member 16, the said notched portion providing a hook 28 on the said member for engagement with the said arm. In order to release the latch member from engagement it is necessary to swing the hook member 16 upon its pivot, which permits the raising of the closure B. By inserting the locking pin 19 through the open ings 14 and 18 this action is prevented.

As will be seen from Fig. 1 the latch is located beneath the receptacle and out of the view of passers by and in order to raise the lid or closure, 18 for the purpose of re moving the contents from the receptacle it is necessary to reach beneath the same and remove the locking pin l9before the latch can be operated. When the latch is not designed to securely locl: will torm a suilicient safeguard to prevent its operation by unauthorized persons.

Having described the invention, that is claimed is:

l. A lock latch comprising an attaching plate provided with a slot, a plurality of openings intersecting said slot, a spring controlled latch member pivoted Within said slot, a spring keeper arm adapted to be brought into the path of the said latch member, a pivot provided in one of the intersecting openings for the mounting of the latch member and a removable pin adapted to be inserted in the other opening and passed through an opening in the said latch the receptacle, it 7 a receptacle a lock latch therefor, said latch comprising an at;

taching plate provided With a slot and a plurality of openings intersecting said slot a spring controlled latch member pivoted in said slot, a spring keeper arm located in the path of the said latch member, a pivot provided in one of the intersecting openings tor the mounting of the latch member and a removable pin adapted to be inserted in the other opening and passed through an opening in the said latch member for lock- I ing the same against independent movement.

In testimony whereof I aihx my s1gnature.

EUGENE PAQUETTE.
