SEAL-LOC K.

SPECIFICATION forming part of Letters Patent No. 341,502, dated May 1l, 1886.

Application tiled February 6, 1886. Serial No. 191,086. (Model.)

To all wwm, it may concern:

Be it known that we, ABNER P. POWERS and SAMUEL WM.'WILKEs, both of Atlanta, in the county of Fulton and State of Georgia, haveinvented certain new and useful Improvements in Seal-Locks, of which the following is a specification, reference being had to the accompanying drawings.

The object of our invention is to produce a seal-lock for use principally upon railroad freight-cars that shall exhibit a particularly cheap and convenient seal of the simplest character of the place or company where the freight is loaded, sealed, and started, and which shall be so arranged that the loch cannot be unlocked or the lock-bolt Withdrawn from its fastening position without destroying the seal. As each shipping-point has its Own peculiar seal it will notbe practicable to open the lock surreptitiously, take the seal out, and replace it by another, and avoid detection between the shipping-point and the point of destination of the loaded sealed car.

In the accompanying drawings, illustrating our invention, Figure l is a side elevation of an ordinary freight-car with our improved seal-lock applied. Fig. 2 is an enlarged side or face View of our seal-lock. Fig. 3 is an end View of the same. Fig. 4 is a face View of the same, partly in section, showing the locking-pin in the locked position. Fig. 5 is a sectional view showing the locking-pin up or in the unlocked position. Fig. 6 is a sectional View showing details. Fig. 7 is a section on the line 7 7 of Fig. 4.

Referring to the letters upon these drawings, A indicates a lock-case, which may be of any ordinary character; B, a lock-bolt or fastening-bolt, secured at one end in any ordinary or suitable manner on the side of a car or on the car-door, and adapted to enter the lock-bolt recess Cwithin the lock. This lockbolt is preferably provided with an opening, D, corresponding to a similarglazed opening, E, in the front plate, F, of the lock-case. It is also preferably provided with a slot, G, for receiving a sealcard, H, which may consist of a simple piece of paper or card-board with any device or design upon it which may be adopted to distinguish it as the particular seal of any 'given shipping-point. The face of this paper seal may be seen through the glazed opening E at all times, so that it can be told instantly by inspection whether it has been tampered with or not. The lock-bolt is notched at I on either side of the opening D.

K indicates a locking-pin, working Vertically in a groove, L, in the back plate of the lock-case. This groove is provided, as shown in the drawings, with undercut guideways on either side, and the pin is provided with flanges N on either side to ttheseguideways. These flanges form a ledge, which strikes against a stop, O, at the upper limit of movement of the pin. Thus it is rendered impossible to pull the pin out or lose it. Near the lower end of the pin we provide a projecting sealcutter, l?. The notehesl in the lock-bolt permit this cutter to pass in and out without obstruction. In order that the cutter may not cut the seal after it has been placed in position in the slot G, and while the pin K is being inserted, the cutter is pivoted in a slot in the pin, as illustrated, and isinclined upwardly, so that as the pin is inserted the back of the cutter will impinge against the card-seal,

which will press the cutter inward out of the way.

Vhen the cutter has passed the seal, it will fall outward to the proper position for hook-A ing and cutting the seal Whenever the pin is withdrawn. The bolt cannot beopened until the pin is Withdrawn, and therefore it is impossible to unlock the lock or Withdraw the bolt Without destroying the seal. In some instances it may be desirable to fasten the pin down, in order that it may not be raised or displaced by the jarring or accidents of travel. XVe therefore provide a spring-latch, Q, which engages with a notch, R, in the lower end of the locking-pin, as shown. This spring-latch may be operated by a key, as usual, or by means of a hook, S.

Ve do not intend to limit our invention or patent protection to theprecise details of construction herein shown and described,beeause considerable variations in details of construction and in matters of form may be made without departing from the substance of our invention, which is the provision of a visible paper seal in connection with a look-bolt, fasteningpin, and cutter, substantially as set forth.

Having thus described our improvements, the lock-bolt B, the locking-pin K, and cutter whatwe claim to be new, and desire to secure H, constructed as set forth, of a spring-latch, by Letters Patent of the United States, is- Q, substantially as described.
