Application filed June 9,

1886- Scrial No. 204,668. (ModeL) Patented in Germany April 1'7, 1886, No. 39,052, and in France April 21, 1886,11! 175,66l.

To aZZ whom it may concern.-

Be it known that I, CARL ZWICKART, of Salzwedel, in the Kingdom of Prussia and German Empire, have invented a new and useful Seal-Lock for GoodsW'agons on Railways, with a Double Safety Contrivance, of which the following is a specification, reference being had therein to the accompanying drawings.

Patented in Germany April 17, 1886,No. 39,052, and in France April 21, 1886, No. 175,6652.

This invention relates to seal-locks for railway, express cars, &c.; and it consists in certain improvements in the construction oflocks of that class, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a general view of the lock mechanism. Fig. 2 is a front view of the lock closed with the safety-bands applied. Fig. 3 is a side view of one of the safety-bands. Fig. 4 is a crosssection of a safety-band.

Referring to the drawings, the two main parts of the lock are designated by B and B, one of said parts being secured to a stationary part of the side of the car and the other being fixed to the movable door, so that when the door is closed a hook or latch connected with one part of the lock enters the opposite part and is caught by a spring bolt or catch.

A and A indicate the lock-plates, to the latter of which is fixed a hook, a, which extends out from one part of the lock in position to enter the other part when the door is closed.

To the plate A is secured a movable bolt, 1), which is provided with a spring, I), the said bolt being constructed and in position to be pressed downward by the hook to when the latter is brought in contact with the bolt, and when the parts A and A are brought close together, as seen in Fig. 1, the bolt 1) immediately rises, being actuated by the spring I), and connects with the hook a, the door being thus locked.

A head, 0, is placed in each of the main parts B B of the lock, each head being in a socket formed in the casing and provided with an angular key-post and circular aperture to admit the key of the look, by which the head may be turned. Each of the heads one of the heads 0, as shown.

C is provided with two arms, 61, extending therefrom, for the purpose hereinafter mentioned. Two levers, f, are pivoted in each of the main parts of the lock, and are severally in position to be engaged by an arm, d, of The levers f are each provided with a tongue or projection, g, a spring, 6, and a guard, m. Four vertical slits, E, are made in the lock-platestwo being in plate A and two in A and one slit in each plate is in position on an extended horizontal line running across the key-holes of the lock. The two lower slits are also arranged in position on a line, one being in each of the loclcplates, as shown.

As will be seen, the tongues g of levers f are severally in position across the slits E, said tongues being intended to connect with the ends of seals inserted in the slit, as hereinafter set forth. Two seals, 01, which are usually formed of tin, the ends of each seal being bent at right angles, as shown, are applied to the outside of the lock with their extremities inserted in the slits E.

The tongues g, or that portion of each tongue which crosses a slit E, is beveled, so

that when the ends of a seal 2' are pressed into slits the tongues are pressed backward. The rectangular extremities of the seals are provided with apertures h, and when the door is closed and fastened by the hook and bolt a and b a seal i may be applied by pressing its extremities into slits E, and the ends of the seal pressing against the beveled surfaces of tongues g, the latter are moved backward, thus allowing the ends of the seal to enter the look, when the tongues are immediately pressed by the springs e into the apertures h, the seal being thus drawn close to the outside of the casing and secured. Guides 11 are fixed to the casing for the tongues g.

The head 0 which is adjacent to the movable bolt 1) is provided with a cam. or projection, 0, by which the bolt maybe withdrawn from engagement with hook at, the head being turned by the key. The levers f may also be pressed backward by turning the heads 0, the arms (1 being constructed to press against them, and the tongues 9 may be thus withdrawn from connection with the ends of the seals 2' in the slits E.

The upper tin seal '5 covers the key-holes, as seen in Fig. 2, and this seal is only applied when additional security is deemed necessary or advisable, the lower seal 1' being generally considered sufficient.

A number of private seals or other identifying-marks may be impressed upon the upper seal by the shipper, if desired, thereby affording additional security against surreptitious opening of the look without detection,

for when the upper seal is used it must be severed before the lock can be opened, and when once destroyed it cannot be replaced or restored, as in the case of a plain seal.

I claim 1. The combination, with a lock-case made in two parts and provided with a securingbolt, of two heads placed in sockets and provided with arms d, two slits, and two pivoted levers provided with tongues which are in position to engage the seals 2', said two levers being adapted to be engaged by the arms of said heads, substantially as and for the purposes described.

2. In combination with a lock-case provided with a slit, E, and a lock-bolt, a head placed in a socket and provided with an arm, d, and a projection adapted to retract the lock-bolt, and a pivoted lever, f, provided with a spring and a tongue, 9, which is in position to engage seal 2', substantially as set forth and described.

3. The combination, with the lock-casing divided into two parts, each having a slit, E, of a seal provided with perforated extremities adapted to be inserted in the slits, and devices, substantially as described, adapted to engage said extremities, substantially as and for the purposes described.

I11 witness whereof I have hereunto set my hand in presence of two witnesses.
