Nita STATES PATENT JOHN HOIVARD MCCORMICK, OF NEIV ORLEANS, LOUISIANA, ASSIGNOR OF ONE'IIALF TO IVILLIAM MEADE MONTGOMERY, OF SAME PLACE.

MAIL-BAG LOCK.

SPECIFICATION forming part of Letters Patent No. 351,063, dated October 19, 1886.

I Application filed April 26, 1886. Serial No. 200,169. (X model.)

To aZZ whom it may concern:

Be it known that I, JOHN HOWARD Mo- CORMICK, a citizen of the United States of America, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Mail-Bag Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to mail-bag locks; and it consists in a lock or fastener for the cords of inail-bags, the peculiar features of which will be fully understood from. the following description, when taken in connection with the i annexed drawings.

Figure 1 is a perspective view of my improved lock, showing a cord applied to it. Fig. 2 is a longitudinal central section of the lock, showing a cord gripped in it by one of the levers or-dogs. Fig. 3 is atop view showing the interior of the lock case. Fig. I is a view of the key. Fig. 5 shows the device ap plied to a bag.

-eferring to the annexed drawings by lettcrs, A designates the case of the lock, which is preferal ly.reetangular and constructed with a pillow, G, leaving a depression, a. Itis also constructed with a receptacle, It, adapted to receive and hold a tag or card, S.

E E designate two curved gripping dogs or levers, which are free to rock on a transverse fulcrum-pin, A, and which are curved somewhat resembling the italic letter-f. Directly over t he flat surface ofthe pillow G the enlarged 5 gripping ends 01' the lovers are serrated, as indicated at I, and at the opposite depressed ends of these levers are slight rounded lugs or wards K K. In the same planes with and near the lugs or wards K K are studs F F,

fixed to the levers. The object of the studs and wards above described is to allow the notched bit of the key I to pass them in the act of unlocking or freeing the cord or rope M from the gripping ends of the levers K K.

B designates the keyhole through one side 5 of the lockrase, directly opposite which is a cupped key-barrel seat, H.

The stepped cone L (shown in Fig. 3) is designed to receive the steps shown on the key in Fig. I.

By reference to Fig. 2 it will be seen that the cord or rope M is passed through apertures O,beneath the long arms of levers K,between the serrated gripping ends of said levers and the pillow G, and out of the case through apertures O. The cord is thus bent or deflected out ofa straight line in its course through the lock-case.

I am aware that serrated gripping dogs or levers, in combination with cases, have been used before my invention for mailbag-rope fasteners, and I do not tl'lerefore claim such devices, broadly.

IVhat I do claim as new is 1. A mail-bag lock consisting of a casehaving a pillow, G, and a depression, a, a keyhole, and perforations for the passage of a cord, in combination with curved levers provided with serrations, substantially as described.

2. The combination, in a mail-bag lock, of 7c the case A, constructed with a tag-receptacle,

a pillow, G, a depression, a, a key-hole and keybarrel cup, gripping-levers E E, fulcrumed at A, and provided with wards K K, studs F F, and serrated gripping ends, and the cord-apertures through the ends of the case, all constructed and adapted to operate substantially in the manner and for the purposes described.

In testimony whereof I aifix my signature in presence of two witnesses.
