SLlDlNG-DOOR LOCK.

SPECIFICATION forming part of Letters Patent No. 556,309, dated March 10, 1896. Application filed April 29, 1895. Serial No. 547,549. (No model.)

open to afford a ventilation, and which will' permit the door of a car to be sealed without locking it in either position.

A further object of the invention is toprovide a car-door lock which will absolutely prevent a car-door from being opened or even unlocked without breaking the wire of the seal.

The invention consists in the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a front elevation of a car-lock constructed in accordancel with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view. Fig. 4 is a detail sectional view of a portion of the lock, illustrating the manner of mounting the locking-pins. Fig. 5 isa detail view of the key.

Like numerals of reference indicate corresponding parts in all the iigures of the drawings. f

1 designates a lock-casing mounted on a oar-door 2 and provided at the adjacent edge of the car-door with an opening 3 for the reception of a hasp 4, which is mounted by means of a pivot 5 vin a vertical slot 6 of a post 7 or the adjacent portion of the carirame against which the car-door abuts in closing. The hasp 4,when not in use or in actual engagement with the lock, swings downward into a vertical position and is concealed within the slot 6 of the car-frame, as illustratedin dotted lines in Fig. 2 of the accompanying drawings, and the car-frame is provided near the lower end of the slot 6 with recesses 8 to enable the hasp to be grasped with the iingers when it is desired to lock the door.

The hasp is provided at its lower edge with a series of notches 9, adapted to be engaged by a vertically-movable bolt 10, mounted in the lock-casing and located beneath the hasp when the latter is in a horizontal position and is inserted in the casing 1. The verticallymovable bolt 10 is provided'on its outer face with a iiange or lug 11', arranged in an opening in the outer face of the casing between flanges 12, surrounding the opening and extended above and below the same a suilicient distance to enable the finger-piece 11 to be readily engagedby the fingers when it is desired to operate the bolt. The bolt is provided with laterally-disposed arms 13 and 14, normally bearing against a transverse flange or stop 15, forming the bottom wall of the hasp opening or way of the casing. The arm 13 is engaged by a coiled spring 16, adapted to hold the bolt normally elevated, and the other arm 14 is engaged by a lug 17 of a rotary head 18, whereby the bolt is locked against downward movement.

The rotary head 18 is mounted on a circular disk or block 19, and has its outer portion arranged withi'ii an annular flange 2O of the casing of the lock, and the head 18 and the disk or block 19 are provided with corresponding sockets adapted to register when the lug is in a vertical position in engagement with the arm 14 or at the opposite side of the head. These sockets receive spring-supported

pins

21 and 22 adapted to be depressed by a key 23 inserted in a slot 24 of the head and provided at its lower edge with projections 25 of different lengths. The projections are adapted to extend through perforations 26 of the head 1S and to engage and depress the series of springsupported pins to bring the adjacent ends of each pair of pins in the same plane as the upper plates of the disk or block 19, as illustrated in Fig. 4 of the accompanying drawings. In this position of the pins the head is adapted to be rotated one-half revolution to carry the lug 17 directly beneath and in engagement with the arm 14 or at a point directly beneath the head and out oi' engagement with the arm 14. In either of these positions the sockets of the rotary head 18 and the stationaryblock IOO or disk 19 coincide or register, and when the key is removed the pins assume the positions illustrated in Fig. 3 of the accompanying drawings, whereby the head is held against rotation when the lug is in engagement with the arm 1-1 and when the lock is unfastened and the lug 17 is out of engagement with the arm 14.

In order to prevent the removal of the key from the rotary head at any other time eX- cept when the lock is fully locked or unlocked and when the pins are in position to engage the rotary head as soon as the key is removed, the latter is provided at opposite sides with notches 27 adapted to receive the annular flange 20 of the lock-casing, whereby when the flange is received within the notches 2" the key is prevented from being withdrawn.

The annular iiange 20 is provided at opposite sides with notches or recesses 28, arranged in alignment with the line of sockets of the stationary block or disk 19, and adapted to permit the key to be inserted and removed only when the sockets of the head 1S and the block or disk 10 register.

The ian ges 12 and E20 are provided with registering perforations 29, the iingeiupiece 11 is provided with a corresponding perforation 30, and the rotary head is provided at opposite sides of the slot 2l with a pair of peforations 3l; and the perforations of the said parts are adapted to register and to receive a wire 32 of a seal 33. Theil the door is fully closed and isV in contact with the ear-frame, the wire 32 of the seal is passed through aperforation Si of the head of a bolt, which forms the pivot 5 of the hasp, and when the door is partly open to form a ventilatingspace the wire is passed through a perforation of the hasp. The car-door is recessed in rear ofthe lockeasing to receive the hasp when the door is completely closed. By this arrangement of perforations the bolt cannot be nroved downward without breaking the wire, and the head 1S cannot be rotated by the key without severing the wire, and the wire does not cross the key-hole, and is not in position to be cngaged by the key, and cannot be jammed into the lock mechanism and work injury to the same or to the key.

A pair of perfor-ations is provided in the rotary head 1S in order to enable the seal to be passed through the heads when the lug is in engagement with the arm 1l of the bolt, or when the lug 17 is rotated to its position beneath the head. It will sometimes be found convenient to seal the door when the lug 17 is not in engagement with the arm of the bolt. This is desirable for use on a train making stops at short distances and where it is not desirable to provide a key at each stop. The seal can be readily broken and the door opened, and the latter may be readily resealed, when desired, without locking the lock with a key, and when the lock is unlocked and sealed the door cannot be opened without breaking the wire of the seal.

It will be seen that the lock is exceedingly simple and comparatively inexpensive in construction, that it possesses great strength, du rability and eiciency, and that it cannot be opened without breaking the wire of a seal.

It will also be seen that the hasp is housed and protected when a car-door is not locked or sealed, and that it will enable a car-door to be readily sealed when it is not locked, and will prevent the opening of a door independent ol the breaking of the seal. Ilurthermore, it will be apparent that the rotary head is adapted to be sealed in either of its positions, and that it is locked against rotation when in either position, and that the key cannot be removed without breaking the sockets in alignment, so that the pins will engage the rotary head.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages ot' this invention.
