FRANK IV. LESLIE, OF CHICAGO, ILLINOIS, 'ASSIGNOR OF ONE-HALF TO SAMUEL C. KANTER AND ISAAC IWI. RICE, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent N o. 590,325, dated September 21, 1897.

I Application filed December 28, 1896. Serial No. 617,165. (No model.)

To all whom t may concern.-

Be it known thatI, FRANK W. LESLIE, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented a new and useful ImprovementY in Envelop-Seals, of which the following is a specification.

My invention belongs to that class of seals in which two metallic disks are locked or clinched together, engaging the aps of the envelop and securely closing it.

It consists of two metallic disks,onc of which has two protruding lugs and the other recesses into which these lugs set, and springfingers over these recesses, which areforced back by the entrance of the lugs, the latter being then turned to one side and locked by the spring-iingers springing back to place as the lugs pass from under them.

Figure l is a plan view of the back of an envelop provided with my seal. Fig. 2 is a plan view of the front with a portion broken away, showing the locked seal on the inside of the back. Fig. 3 is a view of the back with the flap opened, showing the 'projecting lugs and the recesses into which they iit. Figs. 4 and 5 are enlarged perspective views of the two disks'.

A represents the envelop; B, the outer disk; C, the inner disk; D, the projecting lugs; E, the recesses in C, and Ii1 the springfingers upon C.

The disk C is attached in any suitable inanner to the inside of the back of an envelop of the ordinary kind, and is preferably made to engage all of the folds or flaps of it except, of course, the top or outer one, which forms the opening.

The disk lB is attached to the outer flap by the lugs D being inserted through the opening d in it.

The recesses in C are exposed to allow of the entrance of the lugs D by having the envelop cut away, as shown at c, Fig. 3.

When the envelop is to be sealed, the two disks are brought together, the lugs D entering the recesses E and pressed together until the spring-fingers F are forced back. Then by turning the disk B partially around to the right thevlugs pass off of the spring-fingers and they spring back into place and the two disks are locked together and cannot be separated without breaking the seal.

The advantages of this seal are that it occupies very littlespace when made of thin material, being but little thicker than the ordinary envelop; that it can be securely locked without the necessit)r of riveting the parts together and thereby damaging the contents of the letter, and that it can be readily applied to the ordinary form of envelop. It is obvious also that it may be used upon other similar packages.

Vhat I claim, and desire to secure by Letters Patent, is-

l. The herein-described envelop-seal consisting of the combination of the disk B having the projecting lugs D thereon, the disk C having the recesses E therein, and the springfingers F which said lugs engage when they are forced down into said recesses, all substantially as shown anddescribed.

2. The herein-described envelop-seal consisting of the combination of the disk B having the projecting lugs D thereon, the disk C having the recesses E therein, and the springfingers F, located at one side of said recesses E and extending over them, which said lugs engage when they are forced down into said recesses all substantially as shown and described.
