Specification of Letters Patent.
Patented July 1d, 1914:.
Application filed January 14, 1914. Serial No. 812,108.
To (ZZZ c071 one it may concern Be it known that I, ROBERT Gr. MoMAHoN, a citizen of the United States, residing at St. Joseph, in the county of Champaign and State of Illinois, have invented new and useful Improvements in Locks, of which the following is a specification.
The invention relates to looks, and more particularly to the class of sliding door locks for use on freight cars.
The primary object of the invention is the provision of a lock wherein the sliding door of a freight car will be firmly fastened in closed position so as to avoid the accidental sliding thereof resultant from vibration imparted to the car during the travel of the same, thus obviating the possibility of the opening of the door, the lock being of novel form and is readily and easily operated.
Another object of the invention is the provision of a lock of this character wherein the parts thereof are concealed so as to render the lock burglar proof, strong, and durable.
A further object of the invention is the provision of a lock which is extremely simple in construction, reliable and efficient in its purpose, and inexpensive in manufacture.
With these and other objects in view, the invention consists in the construction, combination, and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereunto appended.
In the drawing: Figure 1 is a fragmentary side elevation of a car body with its sliding door, showing the lock constructed in accordance with the invention applied. Fig. 2 is a view showing the lock in longitudinal sectional elevation. Fig. 8 is a sectional view on the line 83 of Fig. 1. Fig. 4 is a sectional view on the line 44 of Fig. 1.
Similar reference characters indicate corresponding parts throughout the several views in the drawing.
Referring to the drawing by numerals, A designates a portion of the side wall of a car body having the usual doorway which is adapted to be closed by the sliding door B, on which is mounted the lock hereinafter fully described.
The lock comprises a two part elongated guide casing 5 in which is mounted a sliding latch bar 6 having a hook end 7 while its opposite end is pivoted at 8 to a link 9, the same being pivoted at 10 to a bell crank lever 11 which is swingingly supported upon a pivot l2-projecting from a base plate 13 secured to the door B, the lower longitudinal edge of handle portion 14 of the lever so as to avoid interference with the working of the lock.
Mounted on the side wall A of the car body at one side of the doorway is a keeper comprising a casing 15 in which is formed a guideway 16 for the hook end 7 of the bar 6, and pivoted in this casing 15 above the path of movement of the bar is a locking pawl or dog 17 which is adapted to swing on the pivot 18 therefor to operate under the tension of a leaf spring 19 suitably fixed within the casing 15 so that the pawl or dog 17 will trip over the hook end 7 for locking engagement therewith when the bolt is projected into the keeper casing 15 on the closing of the door 13, and thus lock the door in said closed position. The pivot 8 connecting the bar 6 and the link 9 together is extended into opposed slots 20 formed in the inner and outer sections of the casing 5 so as to guide the bar 6 to locked or unlocked position.
Mounted in the outer wall of the keeper casing 15 is a key receiving lock barrel 21 which is suitably connected with the pawl or dog 17 so that on the insertion of the key in the barrel 21 the latter can be turned for the lifting of the dog or pawl out of engagement with the hook end 7 of the latch bar 6 so that on moving the handle 14 in one direction the latch bar 6 can be shifted for unlocking the door to free the same.
The meeting walls of the casings 5 and 15 are formed with alining loops 22 through which can be passed any ordinary wellknown form of car seal so that should a malicious person be successful in releasing the lock it will be necessary to mutilate or break the car seal for the opening of the door, and thus indicate an unauthorized entrance to the car.
From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.
What is claimed is Y A lock of the class described comprising a lock casing adapted to be secured to the easement of a door, a bolt casing adapted to be secured to the door and having alining slots in opposite sides thereof, the said last named casing being provided with a slot at same, a spring acting upon the pawl to hold right angles to the first named slot, a sliding the same in'the path of movement of the bolt in said bolt casing and movable into the bolt, and key operated means within the look casing, a bell crank shaped lever pivlook casing for moving the pawl to released 15 oted Within the bolt casing and movable position.
through the last-named slot, a link conneot- In testimony whereof I aflix my signature ing the said lever with the said bolt, one of in presence of two witnesses.
the connections of the link being slidable in ROBERT GEORGE lWoMAHON. the first-named slot in the bolt casing a lVitnesses: I
