CAR-DOOR LOCK Specification of Letters Patent.
Patented Dec. 29, 1908.
Application filed August 5, 1908. Serial No. 447,166.
To all whom 7t may concern:
Be it known that we, \VILLIAW and Tnoans ll. \Varrs. citizens of the United States. and residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Car-Door Locks, of which the following is a specification.
This invention relates to a lock or fastening device which is more particularly intended for use on the horizontally sliding doors of box frei ht cars. The locks or his tenine's for sue doors have heretofore usually been applied to the side of the door and car body at. which place they are easily accessible and subject to tampering by unau thorized persons and render it possible to burglarize the car without detection.
It is the object of this invention to provide a lock or fastening for ear doors of this character which is so constructed that. the same must. be operated from the top of the car, thereby rendering it more diificult. to tamper with the same and also increasing the risk of detection if a burglar should at tempt to operate the lock. In the accompanying drawings consistin si e elevation of the car provided with our improved door lock or fastening. Fig. 2 is a. horizontal section thereof in line 2--- -2. Fig. 1. Fig. 3 is a fragmentary vertical longitudinal section in line il tl. Fig. "2. Fig. 4 is a top plan view of the lock and the adjacent parts of the car body. F igs. 5 and 6 are fragmentary vertical transierse sections in the correspondingly numbered lines in Fig. 1. Fig. 7 is a perspective view of the handle or operating bar of the lock. Fig. 8 is a similar view of the upper end of the locking shaft.
Similar letters of reference indicate corresponding parts throughout the several views.
The box car to which our invention is applicable may be of any suitable construction that shown in the drawings consisting of a body A and a door B which slides horizontally and lengthwlse at. its upper and lower edges in guides 12, b. The forward movement of t e door when in its closed position is arrested by means of a stop 0 which is secured to the outer side of the car bodv and engaged by the front edge of the door.
Our improved lock or fastening for holding the door shut is constructed as follows;
l l l l l l t l r l i l l l l l t of 2 sheets: Figure l is a fragmentary 1 1) represents J. blomuann l which 1s arranged on the inner side of the an upright locking shaft.
path of the door and adjacent to the rear edge thereof when the same is in its closed position. At its lower end the shaft. is provided with a reduced pivot pin or trunnion e which is journaled in a bearing plate Eisecured by belts or otherwise to the lower part of the car body while its upper part is provided near its upper end with a reduced cylindrical neck F which is journaled in a bearing plate f secured to a block G on top of the car body by bolts or other suitable means. Between the top and bottom of the car the locking shaft is provided with one or more laterally projecting lugs or steps h which are adapted to be swung outwardly so as to project across the path of the door and engage with the rear edge thereof upon turning the shaft in one direction and there-- by hold the door against opening. as shown in Figs. l. 9. and 5. or to be swung inwardly clear of the path of the door upon turning the shaft in the opposite direction when it is desired to release the door and permit the same to be opened. The locking shaft and its stop lugs are arranged in a recess formed in the side of the car consisting of a main upright portion I which receives the main part of the shaft. and two branches at, 2' extending rearwardly from the main portion and adapted to receive the stop lugs when the same are in their retracted position.
Above its upper bearing the locking shaft is provided with a shank J and at its upper end the same is provided with a collar ll which is secured thereto by a transverse rivet, as shown. or in any other suitable manner. Mounted upon this shank so thatit is compelled to turn with theshaft but is free to move axially thereon independently of the same, is an operating handle onbar L whereby the shaft is turned and which also forms part of, the means whereby the shaft and its stop lugs are held in their locked position. The means for thus connecting the handle to the shaft consists in making the shank thereof of rectangular form in cross section and providing the handle with an opening 1 of corresponding form to receive said shank. The handle is preferably constructed in the form of a cross bar which projects radially from opposite sides of the shank so that both hands may be employed for turnin the same and the locking shaft. When the lattcr has been turned forwardly 2. A car door lock comprising an upright shaft journaled on the car body on one side of the path of the door and having a projection adapted to be moved into and out of the path of said door by turning the shaft in one direction or the other, a handle connected with the upper end of said shaft so as to be compelled to turn therewith but capable of moving axially on the shaft independently thereof. and a sta do which is arranged on top of the car and which is adapted to engage with an opening in said handle and to receive a fastening for holding the handle on said staple.
3. A lock for horizontally sliding car doors comprising an upright shaft journaled on the car body on the inner side of the path of into its operative position in which its stop I lugs project across the rear edge of the door, the handle bar is arranged lengthwise in line with the block G on top of the car. Upon reaching this position, the handle bar may be secured against movement for holding the shaft in its locked position by any suitable means, that shown in the drawings being suitable for this purpose and consisting of two staples m, m projecting upwardly from opposite ends of the block G through opt-tr ings n, n in opposite ends of the handle bar, a pair of pins 0, 0 passing transversely through said staples above the handle bar and being connected to the car body by means of chains 0 or other suitable flexible connections and a wire seal P applied to the front end of one or both of said pins for the purpose of preventing unauthorized withdrawal of the same;
While the handle bar is being turned together with the locking shaft it: is raised on the rectangular shank thereof, so that it sweeps clear over the upper ends of the staples, but after the handle bar has turned engage with the rear edge of the door and having a rectangular part which projects above the top of the car and a collar at its upper end, a handle having a rectangular opening which receives the correspondingly shaped part of said shaftbelow said collar and is capable of turning with the shaft and the locking shaft into its operative position moving axially thereon, and means for fasthe handle bar is slid downwardly on the tenin the handle to the top of the car. shank for engaging its openings with the 4. i lock forhorizontally slidingcar doors staples of the block preparatory to inserting the pins or other fastenings to the staples.
The parts of our improved locking device which engage directly with the door and which are accessible from the ground are very strong and durable and cannot be easily comprisin an upright shaft journaled on the car body on the inner side of the path of the door and having a projection adapted to engage with the rear edge of the door and having a rectangular part which projects above the top of the car and a collar at its broken.
