EMILE AUGUST BRANDAU, OF LOS ANGELES, CALIFORNIA.

MAIL-BAG FASTENING.

SPECIFICATION forming part of Letters Patent No. 256,539, dated April 18, 1882.

Application filed July 13, 1881. (Model.)

To all whom it mag concern:

Be it known that I, EMILE AUGUST BRAN- DAU, holding a declaration of intention of citi zenship of the United States, residingat Los Angeles, in the county of Los Angcles and State of California, have invented a certain new and useful Mail-Pouch Fastening; and I do declare the following to be a clearand exact description of the invention, reference being had to the accompanying drawings,and to the figures of reference thereon, which form part of this specification.

My invention relates to improvements in mail-bag fastenings in which a permanently fixed cranked rodby a quarter rotary movement operates in conjunction with two jaws and a staple.

The objects of my improvements are, first, to avoid the turning around of the mail-hag; second, to secure in a more firm manner the opening of the bag; third, to afford facilities for the greater dispatch and delivery of mailmatter. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an isometrical view of a mailbag, showing the fastening locked; Fig. 2, a frontelevation showingthefastening unlocked; Fig. 3; a front elevation of the rear bed-plate; Fig. 4, a section on the line 1 2, Fig. 2, showing the fastening unlocked; Fig. 5, a side elevation; Fig. 6, a section taken on the line3 4,

Fig. 2; Fig. 7, an isometrical view of the cranked rod 0.

Similar letters refer to'similar parts throughout the several views.

The bed-plate b is attached on the front of the cover of the mail-bag. Forming part of the same bed-plate are the bearings cl d d d (1 (1 in which rests and operates in a quarter rotary movement the cranked rod 0, constituting the principal feature of the fastening.

The address-plated a is hinged to the top part of the bed-plate b, and is provided with a slot, 8, in a corresponding. position to the center of the bed-plate b.

Secured to the inside face of the rear part of the mail-bag is a similar bed-plate, a. (See Fig. 3.) Attached to this bed-plate, and forming part of the same, are the jaws e e and the In order to give a free passage to the jaws .0 e and the staple 7a through the slots in the bedplate b,it is necessary that the cranks a u should lie flat against the bed-plateb, which, upon being pressed down on the bed-plate a, allow the jaws e c and the staple Ic to'come through their corresponding slots, m m" M in the bed-plate b the cranked rod 0, upon being turned so that the crank a passes over the staple it, simultaneously brings the cranks u a into the openings of the jaws e e and forms a lock with the same. The address-plate a a is then brought over the slot 8 in the same,

closing over the staple 70, which projects far enough out from the face of the address-plate a a to allow of the introduction of the hasp of the padlock. By utilizing the address-plateau in this manner it serves as a check upon the cranked rod 0 being turned, and upon the releasing of the cranks u a from the openings in the jaws e c after the padlock is attached.

.The jaws e e, and the staple k, instead of being on one continuous bed-plate, may each have a separate bed-plate, so as to decrease the weight of the entire fastening.

I prefer to carry out this feature of my invention as shown on Fig. 3, as it insures a more ready adjustment of the jaws a e and the staple k to their corresponding slots in the bed- To insure greater security to the mailbag, 5

there may be provided two eyelets in each side of the mail-bag of similar shape to the slots in the bed-plate I). These eyelets will be in such a position that in folding in each side at the top toward the center or inside they will come to- ICO gether and allow thejaws cc to pass through, so that when the cover of the mail-bagis closed down and the fastening locked the folding in of the sides will efiectually prevent any mailmatter passing out or of being abstracted at the top of the sides of the mail-hag.

hen the pouch is filled with mail-matter it will be the means of giving it a wedge shape at the top, as would be seen in a section taken from the front to the rear of the bag, thus drawing thejaws c e in a downward direction and causing the cranks a u to press well up into the openings of the jaws, leaving no chance of the cranks being moved from their locked position.

ltiveted to the padlock 1) p is a bar, to which is attached one end of a swivel-chain, the other end of the chain being riveted to the mail-bag in the manner shown in Fig. 1, so that when the padlock is removed from the fastening of the bag there is less probability of its being lost or mislaid than when itis not so secured.

I am aware that prior to my invention mailbag fastenings have been made and used with staples, and the address-plate used in conjunction with a staple and a padlock. I therefore do not claim such a combination, broadly; but

What I do claim as my invention, and deslre to secure by Letters Patent, is-

1. The combination, in a mail-bag fastening consisting of the rod 0, turning in hearings or supports upon the closing-flap of the bag, and provided with cranks, which may be en ga ged and held, after thebag is closed, by hooks or jaws c e and the staple k, projecting from the rear of the bag through slots in the plate upon which the cranked rod is mounted, substantially as herein described.

2. The bag having the flap or cover provided with a shaft, 0, having cranks adapted to en gage hooks or jaws e e! and staple 7. which projects through the cover from the rear wall of the bag, in combination with the hinged slotted address-plate a a, which may be folded down over the staple, and the crank a, substantially as and for the purpose herein described.

3. In a mail-bag in which the side portions are adapted to be turned or folded into the body, as described, the openings or eyelets through the folded portions, in combination with the jaws e c, the staple 7c, the cranked rod 0, and the hinged folding address-plate a a, substantially as and for the purpose herein described.

EMILE AUGUST BRANDAU.
