SEAL- ESPECEFEGATIN forming part of Letters Patent No. 334,407, dated J auuary 19, 1886.

Application filed October l, 1885. Serial No. 178,700.

To all whom t may concern:

Beit known that we, GEORGE H. ANGELL and CHARLES L. LESLIE, citizens of the United States, residing at'Omaha, in the county of Douglas and'State of Nebraska, haveinvented certain new and useful Improvements in Seal- Loeks, of which the followingisaspeciication, reference being had therein to the accompanying drawings.

Oui invention relates to improvements in car-sealing or seal-fastening devices by which said fastening cannot be opened without indicating the same to have been done.

Our improvement consists in the mechanism illustrated in the accompanying drawings, in which- Figure l is a face view of a seal-lock constructed in accordance with our invention; Fig. 2, a vertical section of the same; Fig. 3, a side view of the same; Fig. 4, a rear View of the face-plate; Fig. 5, a horizontal section of the lock; Fig. 6, a top view of said lock. Figs. 7 and 8 are front views of sealing-cards used with the lock. Fig. 9 is a front perspective view of the lower portion of the back plate of the lock. Fig. 10 is a horizontal section of the front and back plates and sealing-card on line x x of Fig. 2. Fig. 1l is a perspective view of a knife-plate carrying two blades. Fig. l2 is a front view of a slightly modified form of our lock, in which the knife projects from the rear ofthe sliding front plate. Fig. 13 is a side View of the same. Fig. 14 is atop view of the same.

The back plate, A', of the lock has generally projecting from its upper end an arm, A,

bent in the form of ahook, having its free end extending forward of the back plate and entering a socket, B, formed for its reception in the upper front portion of the face-plate F. From the lower portion of said face-plate projects a lug, C, by which the face-plate can be drawn downward to withdraw the end of the hook from its socket and open the lock.

From the rear of the back plate projects a perforated lug, D, to retain one end of a chain to fasten the lock to a car.

The back plate,A,has its vertical edges provided with grooves A to receive the edges of the front plate and permit the latter to slide for a limited distance in said grooves, said distance being sufficient to permit the sealing- (Model.)

l card E to be placed in position when the front plate is open to its extreme lower limit.

Frein the lower portion of the back plate, A, projects toward the front the knife H, having its edge upward, against which the sealing-card rests when the seal is closed. This knife can be either rigidly secured to the back plate, in which case the sealing-card has to'be slightly sprung or bent vertically to insert it past the knife into the lock, or the knife or knife-blades can be mounted on a spring or secured to a thin steel plate, h, retained by screws passing through slots that permit it to spring back against the back plate while entering the sealing-card into the lock. This arrangement may be reversed, and the seat for the card and the knifeway may be in the back plate, as shown in Figs. l2 and 13, and the knife H'l be secured to the rear of the faceplate to rest upon the top edge ofthe sealingcard and cut the latter vertically in two from top to bottom before the lock can be opened.

For the passage of the knife H, attached to the back plate, avertical groove or knifeway, I, is formed in the back of the front plate. This plate is also provided with a rectangular recess, F2, 'to retain inl position the glass or transparent covering G ofthe seal,and a larger but less deep recess, F3, to receive the sealingcard E.' The sealing-card may be composed of paper, cardboard, wood, lead, or of sheet metal-as tin, brass, copper, Ste-and made of such width, length, and thickness as will fit snugly in the receptacle F3 provided for it in the lock, and be cut or tornin two or more separate parts while forced against the edge of the knives. The sealing-card may be made with a portion punched out near its lower edge, as shown at c in Fig. 7, through which the knife H enters in position to cut or tear through the balance of the card, leaving a marginbelow to hold the parts of the card together. The sealing-card bears printed or stamped inscriptions and numbers, from which it can be recognized. Thereis an opening, F, in the face-plate, through which and its glass G the sealing-card can be seen, and any tampering with the lock be discovered.

We are aware that seal-locks have been formed with a hollow body carrying therein a pivoted knife, and a shackle passing through said body and having a recess for the recep- IOO tion of a card adapted to bear against the edge ofthe knife, and do not elaini this construe tion. Neither do We elaini a seal-lock provided with a bolt Carrying` a knife at its outer end in connection with a easing containing a card to be split by said knife in opening the lock.

Having now fully described onr invention, whatwe claim, and desire to secure by Letters Patent, is-

A seal-look consisting,` of two plates ofnietal, the front one of which is adapted to slide vertieally in grooves Within the back plate and is provided with a projecting` lng on the front
