- SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 370.414, dated September 27, 1887.

Application filed December 9, 1886. Serial No. 221,110. (No model.)

To all whom it may concern:

Be it known that I, JAMES S. Ronan, a citizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented certain new and useful Improvements in Seal-Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of'this invention is to provide a new and improved car-door seal-lock, to be attached to the inside of said door, which will be simple and inexpensive and will show if the door has been opened by any person having the proper key. I accomplish this object by the construction illustrated in the accompanying drawings, in which- Figure 1 represents in perspective the lower portion of the sliding doors of a freight-car partly open and provided with a seal-lock constructed in accordance with my invention. Fig. 2 is a horizontal section through a portion of one of the car-doors on line x a: of Fig. 3. Fig. 3 is a front view of the lock with its hasp retained therein and its cap-plate removed. Fig. 4 is a vertical section on line yy of Fig. 2 of the cap-plate, showing the cardperforating blade retracted, as within the lockframe.- Fig. 5 is a similar vertical section of the cap-plate, showing the card-perforating blade projecting through a slot in the capplate in the position it'occupies after perforating the card. Fig. 6 is aperspective view of the cap-plate, showing the inner side thereof with the blade pivoted thereto and its operating-lever. Fig. 7 is a perspective view of the key used with the lock. Fig. 8 is a perspective view of the hasp-bolt and the plate to which it is hinged.

In said drawings, A represents one door of a car, and A the other, adapted to slide upon ways A2. To the inside of the door A is secured a plate, B, having hinged thereto at b the hasp-bolt B2, having a series of notches, b2, either one of which is adapted to receive the end of the latch-bolt O, forming a part of the lock, so that the doors may be retained ajar, if desired, by said bolts. door A is secured the lock-case D, having two compartments separated by the horizontal partition D". The upper compartment is simply to receive the hasp-bolt, while the lower one To the inside of the contains the body of the latch-bolt C, its spring C2 pressing against its lower end, and also the lever E, carrying the card-perforating blade f. Said lever E is provided with trunnions or lugs e, projecting from opposite sides thereof, to enter cavities in the lock-case D and its cover D and permit it to partly rotate under the impulse of the key K, acting against the under side of its short arm e2, or under the impulse of the dat spring g, pressing against its upper side. The long arm e3 of the lever E is of suitable form and slotted to receive the inner or hinge end of the blade f. Said inner end is perforated to receive the pin f2, that passes also through the long arm e3 of said lever. The blade f has also a longitudinal slot, f3, for the passage of the pivot-pin d, upon which it can rockin and outof a vertical slot,

d', made in the cover D. This pivot-pin d passes through lugs d2, projecting from the inner surface of the cover.

Between the end of the short arm eZ and the latch-bolt C the guide-pin h for the key projects from the bottom of the lockcase, and adjacent to said pin the ward-high2 projects also from the bottom of said case. The key has two bits, one on each side, so that when it is turned the bit k bears against the upper side of a shoulder, c, on the latch-bolt C, While the opposite bit, k2, of the key presses against the under side of the short arm c2 of the lever E, partially rotates the latter, and forces its blade f with a draw cut through the slot f 3 and through the index-card. This card is placed in a broad but shallow groove, d, cut in the outer face of the cover D', and bears against the inner side of the door A. At that point said door has a cylindrical opening, a, that is closed by a glass pane, a2, retained by the escutcheon H.

In front of the key-hole d4 the cover D ofthe lock has projecting from its face a guard, D2, in the form of a hollow cylindrical chamber, the outer wall of which has a key-hole, d, to admit .the key when the latter is so turned that the bits thereof are in a vertical plane, and a partition, D3, is located about half-Way ofthe chamber, in which the key-hole is of such shape that the key is held with its bits' standing horizontally to pass therethrough, so that to introduce the key into the lock it has to be IOO inserted first with its bits standing in a vertical plane through the key-hole in the outer wall of the cylindrical chamber D2, then turned one-quarter of a circle and passed through the key-hole in the partition DB, and then turned lock.

To the outside of the door A is secured the escutcheon H, having two conical cavities, H and H2. The cavity H is directly in line with the key-hole of the lock and protects the body of the key when the latter is in the lock, and the pane of glass a, being in the bottom of the cavity H2, is thereby protected by the body of the escutcheon. The latch-bolt C has projecting from two of its sides pins c', that extend through vertical slots t' in the rear and inthe edge of the lock-case, and can be pressed upon to depress the bolt C from theinside of the car, and thereby uncouple or unfasten the doors from the inside, if desired.

Having now fully described my invention, I claiml. The combination of a sliding car-door and a lock-case secured to the inside thereof and provided with a spring-latch inclosed therein, with a sliding door, a plate, B, se-

cured thereto, and a hasp-bolt hinged to said plate to swing in a horizontal plane and provided with a series of notches, substantially as and for the purpose described.

2. The combination of the hasp-bolt B2, having notches therein, with a lock-case' having a horizontal partition therein,'the spring-latch passing therethrough, the lever E, pivoted to said case, a spring bearing upon one end of said lever, a blade pivoted at one end to such lever, and a pivoted pin passing through a slot in said blade, substantially as and for the purpose described.

3. The combination of a hasp-bolt having notches therein, with a lock-case, a springlatch, and a lever having a card-perforating blade pivoted thereto, the `cover of said lockcase having in front of its key-hole aguard, D2, provided with a transverse partition and an escutcheon having a cavity corresponding u with said. guard, and a cavity having a glass bottom in` front of .the card-perforating blade of the lock, substantially as and for the purpose describedA n In testimony whereof I ax my signature in presence of two witnesses.
