SPECIFEC'ATION forming part of Letters Patent No. 372,653, elated November 8I 1887.

Application tiled January 2G. 1887. Serial No. $25,503. (Model.)

To @ZZ whom, it may concern.a

Be it known that I, GLAUDiUs V. Bouca- 'roN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in SealLocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

y invention relates to that class of seallocks in which the locking mechanism is covered by card board or other easily-destructible material, the breaking or destroying of which is necessary in order to separate the locked parts.

It is my object to provide a seal-lock which is not only applicable to sealing the doors of ears, but can be applied equally as well to ilexible bags containing money, mail, or other valuables.

lVith this object in view my invention consists, essentially, of a back-recessed plate containing spring-pressed pivoted catch-plates, and a front plate with oblong openings and provided at its sides with notched spurs `adapted to enter sockets in the rear plate and engage with the spring pressed pivoted catches to lock the two plates together. Between these two plates and over the locking mechanism is placed the card, upon which the necessary inscriptions are so placed as to show through the oblong openings in the front plate. A strip of very thin metal, preferably brass, is placed through the lock or around the bag, and its doubled ends pass down between the card and rear plate, being secured in such po sition against removal by pins upon one plate, which pass through the metallic strip and enter sockets in the other plate.

I will now proceed to describe definitely the approved manner in which I propose earrying out my invention.

In the drawings, Figure l shows my improved seal-loek applied to a money-bag. Fig. 2 shows rear plate with its locking mechanism. Fig. 3 is an end view of the front plate. Fig. 4 is a cross-section taken in the line x x of Fig. l, and Fig. 5 is a view of the inscribed card.

Referring to the drawings, a is the rear plate of the lock7 preferably square, and recessed or cut out upon one of its faces to make room for the lockiu'g mechanism. Within this recess a' is arranged the catch plates b b, each pivoted at b, and having the inward extensions bz b'2 lapping beyond each other, with a narrow space between them to allow of the insertion of a key or other device, by means of which they can be turned in opposite directions in unlocking the seal, as will be hereinafter explained.

c c are springs having one of their ends embedded in the plate (t, the other ends resting against the catch-plates b b. W'ith the aid of the rigid pins c c, located behind the springs, these springs c c hold the catch-plates I) b in the normal position shown in Fig. 2, their edges resting loosely under the projections a CL2, extending outover the recess a.

d d are sockets in the sides of the plate a, adapted for the reception of the notched spurs ofthe front plate. d d are similar but smaller sockets in the plate a, adapted for the reception of pins upon the front plate, and d d2 are small pins or spurs which pass through and hold the card.

e is the front plate of the lock, having the oblong openings c', formed by the cross-bars e?. Centrally arranged upon the under side of this plate at its sides are the beveled spurs c, provided with the inside notches, e, these notched spurs being adapted for engagement with the sockets d d of the plate e.

ci e5 are pins upon the underside of the plate e, adapted for engagement with the small sockets d d of the plate c.

fis the card adapted to be placed between the plates a and e, the spaces f being properly inscribed and adapted to show through the openings e in the plate e.

fzj'Z are notches in the sides of the card, in 95 which the spurs e e3 rest and prevent the card from being moved from its position.

g is the strip, made of very thin sheet brass, which I employ with my improved seal-lock.

rllhe operation of adjusting the various parts just described and locking the two plates to- IOO gether is substantially as follows: As shown in Fig. 1, the strip g is applied as securing the mouth of .a money-bag, it being threaded through slits in the bag, as shown. The loose ends are held together, andin that position are placed upon the rear plate, a, in a line with and covering the small sockets d d', as shown in dotted lines in Fig. l. The card f, preferably of stiff paper, is neXt placed in a central position upon the plate e andsover the ends of the strip g. Upon these is placed the plate e, which is pressed down thereon, the pins e5 puneturing the ends of the strip g, the pins d d2 puncturing the card, and the notched spurs entering the sockets d d of the plate c. As the spurs e3 enter, their beveled ends -push aside the spring catch-plates Z1 b until the notches ek e4 in the spurs reach the plates b b when their s ide edges are sprng into the notches by the aid of the springs c c, thus effectually looking the two plates together with the card and stri p securely held between them. The plate e can only be disengaged from the plate a by moving the catch-plates b b out of engagement with theA notched spurs c of plate e. This could be effected by applying pressure through the card f against the edges b b3, provided they were accessible; but it will be observed by reference to Fig. 2 that the bars e2 e" of plate e (shown in dotted lines) cover these edges b3 b* when the two plates are locked, thus effectually preventing tampering with the lock at these points. The only other way of unlocking the plates is by cutting away the card and the ends 1. A seal-lock comprising a rear plate hav.- 45 ing arecessed and socketed inner face, springheld catch-plates having pivotal bearing Within said rear plate and adapted to extend partly across the adjacent sockets in said rear plate, said catch-plates having at their inner edges 5o 'overlappingdiseonneeted extensions, ametallic strip or seal, an address-Card having notched vedges and resting upon the rear plate, a front plate having a slotted face to permit of the exposure of the address onthe address-card, .and 5 5 depending spurs adapted, respectively, to grip the metallic strip and card and to engage the pivoted catehplates, substantially as set forth.

2. A seal-lock consisting ofthe rear plate, a, recessed'at a and having the sockets d d and 6o d d in its sides, and the spring-pressed catchplates b b2 and b b2, pivoted within said recessed portion, and the front plate, e, with recesses e e e and cross-bars e2 e2, the notched spurs c3 c4 and e3 et, and the pins orspurs c5, the two 65 plates adapted, as shown, to lock between them the metallic strip g and the card f, substantially as shown and described.

3. A seal-lock consisting of the rear plate, a, recessed at a and having the sockets d d and 7o d d in its sides, and the spring-pressed catchplates b b" and b b2, pivoted within said recessed portion with their' edges extending under the projections a2 a2, and the front plate, e,with recesses e e e and cross-bars e2 e2, the notched 75 spurs e* eAL and ei' e, and the pins or spurs ef", the two plates adapted, as shown, to lock between them the metallic strip g and the card f, with the side notches, ff, substantially as shown and described. 8o

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.`
