OF ANAMOSA, IOWA.

FREIGHT-CAR LOCK.

SPECIFICATION forming part of Letters Patent No. 348,715, dated September 7, 1886.

Application filed April 12, 1886. Serial No. 198,581.

To all whom it may concern:

Be itknown that l', GEORGE J. BEDFORD, of Anamosa, in the county of Jones and State of Iowa, have invented a new and Improved Freight-Oar Look, of which the following is a full, clear, and exact description.

My invention relates to the construction of a hasp-lock applicable to any form of door, but designed more especially for use in connection with a freight-car door or other form of door that it is necessary to seal.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a face view of my improved form of lock. Fig. 2 is a sectional view taken on line at x of Fig. 1. Fig. 3 is a view of the inner side of the lock, the face-plate of the lock and the face-plate of the tumblercase being removed to disclose the interior construction. Fig. 4 is a sectional view of the lock,taken on line 3 3 of Fig. 1, the key-spindle being moved around aquarter-turn. Fig. 5 is a detail view illustrating the construction of the inner plate of the tumbler-case. Fig. 6 is a similar view of the outer plate of the tumbler-case. Fig. 7 is a detail View illustrating the construction of the eyebolt in connection with which the lock is employed; and Fig. 8 is a perspective view of the key-spindle.

In constructing such a lock as is illustrated in the drawings above referred to,l provide a heavy case, A, that is hinged to a bolt, B, adapted to be secured to the body of the car by means of a nut, B. The interior of the case A is divided into two compartments by a partition, f, in the larger one of which there is arranged a tumbler-case, G, in which any number of tumblers, a a a, are arranged, said tumblers being provided with central openings, b, the size of which varies to correspond with the wards of the key D,,and with side openings, 0, that are T-shaped, and so relatively placed that when the key is in the lock the openings in all of the tumblers will register. The tumbler-case O rests against the outer face of the lock-case, and is guided by pins or lugs 11 d, projecting inward from said outer face, and by the locking-bolt E, which is made integral with the forward side, 6, of thecase 0, and extends through the partition f, which di- (Model) vides the lock-case into two compartments. The inwardly-extending post F is arranged so as to pass through the openings 0 in the tumblers a, and also through an opening, 9, formed in the plate G, which constitutes the outer plate of the tumbler-case, the extreme end of the post F projecting through an opening, h, formed in the inner plate, H, of said tumbler-case, which plate is secured to the forward and rear walls, 6 e, of the tumblercase, as will be readily understood, while the extreme end of the post F is formed with a projection, f, which extends through the rear plate, It, of the lock-case, said rear plate being held to the main case A in any manner desired.

The lock-spindle N (the construction of which is best shown in Fig. 8) is fitted in an aperture, 2', formed in the outer face of the lock-case, and is provided with a collar, n, which fits against the outer face of the case A, and a toe, 0, by which the tumbler-case is thrown forward or back as the lock-spindle is rotated. Projecting inward from below the toe 0 there isa shank, p, which extends through the end plate, R, and is there engaged by a pin,. p, which serves to hold the lock'spindle in position. The key D is inserted through the aperture Z,formed in the lock-spindle, and the inner end of the key is supported by a pin, m, which passes through the shank p, a notch, It, being formed in the key to fit upon the said pin on.

In the plate B there is an opening, q, de signed to admit the projecting end of an eyebolt, T, which is secured to the door of the car, the opening it in the head of said eyebolt being arranged so as to be entered by the lockingbolt E when said dog is thrown forward into a smaller compartment of the lock-case. The bolt T is provided with an extension, S, formed with an aperture, 8, and this extension S enters a hollow cap, U, that is secured to the outer face of the lock-case, openings u a, which register with the slot 8, being formed in said cap U.

This lock is designed to operate in a horizontal position, and is so arranged that when turned against the face of the door, so that the head of the bolt T enters through the opening or aperture q, and the bolt E is thrown forward, the tumblers a a will fall so that their weight will be supported by the post F, which at this time will be in the vertical portion of the T- shaped slots 0. Now, to throw back the bolt E, the key D is inserted in the lock-spindle N and the spindle and key are given a quarter-turn, which movement will throw the tumblers upward, so that the horizontal portions ot the slots 0 will be in line with the post F and all of the slots will register, and a continued turning of the spindle will bring the toe 0 into engagement with the plate G, and the to mbier-case and with it the bolt will be thrown backward to clear the lockingbolt E from engagement with the eyebolt T, the post at this time entering the horizontal portion of the slots 0. \Vhen it is desired to again throw the locking-bolt forward, it may be done by simply turning the key-spindle. After the door to which the lock described is applied has been locked, and it is desired that the lock should be sealed, a wire, o, is passed through the apertures u u of the cap U and the aperture 8 of the extension S, and the ends of the wire are united by a seal, V. In the outer end of the key-spindle there is a slotted plug, N; which, when the key is withdrawn, maybe turned to close the key-slot, thus keeping out dirt and moisture.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- I 1. In a lock, the COHlblllZthlOlLWlth a sliding tumbler-case and a locking-bolt carried thereby,ol"a slotted key-spindle formed witha toe, 0, substantially as described.

2. The combination, with a lock-case and its supportingbolt to which the case ishinged, of a Sliding tumbler-case and its tumblers, a key-spindle formed with a central slot or opening, Z, and provided with a pin, m, and a toe, 0, and a rigid post,F, adapted to extend through apertures formed in the outer and inner plates of the lock-case and through T-shaped openings formed in the tumblers, substantially as described.

3. The combination, with a loclrcase, of a tumbler-case provided with a locking-bolt and held to slidein said lock-case, tumblers in said tumbler-case, and a longitudinally-apertured key -spindle journaled in the lock case and adapted to engage the tumbler-ease, substantially as described.

4. The combination, with a lock-case, of a blers in said tumbler-case provided with key- I apertures and T-shaped guide slots, a post held in the lock-casing and passing through the T-shaped slots of the tumblers, and alongitudinallyapertured key-spindle journaled in the lock-case, passing through the key-apertures of the tumblers, and provided with atoe, 0, substantially as described.

6. The combination, with a lock-case and its supporting bolt, of a locking mechanism and an eyebolt with which the locking mechanism engages, a cap, U, connected to the lock case, and an extension formed on the eyebolt and entering the cap on the lock-case, the extension and the cap being formed with registering openings, substantially as described.

7. The key-spindle N, apertured at l, and provided with shank p, collar a, toe o, and pin on, substantially as described. a

8. The combination, with the key-spindle N, of the slotted plug N, substantially as described.

9. The combination, with a keyspindle apertured longitudinally at I, provided with a slotted shanlgp, and with atoe, o, and having apin, m, crossing the slot in the shank, of a key, D, fitted to the aperture of the spindle and provided with a recess, k, substantially as described.
