lFREDIERIGK EDWIN LEIG-HTON, OF MILLIBRIDGE, MAINE, ASSIG-NOR OF ONE-HALF T JAMES S. WYMAN, OF MILLBRIDG'E, MAINE.
GAR-DOOR LOCK.
Specification of Letters Patent.
Patented Mar. 26, 1912.
To all whom it may concern:
Be it known that I, FREDERICK E. LEIGH- TON, a citizen of the United States, residing at Millbridge, in the county of Washington and State of Maine, have invented certain new and useful Improvements in Car-Door Locks, of which the following is a specication.
My invention relates to improvements in car door locks and the leading object of my invention is the provision of a locking mechanism which can be applied to the car at a small expense and which can be locked and released with ease by the proper person but which will securely lock the door at the top and lower port-ion and be proof against opening or tampering with.
Another object of my invention is the provision of a car door lock which will occupy a small space and which will withstand hard service and not fail in its action and which in general will prove eficient and practical.
To attain the desired objects my invention consists of a locking mechanism for car doors embodying novel features of construction and combination of parts for service fsubstantially as disclosed herein.
In order that the detailed construction and the operation of my locking mechanism may be understood andits advantages be appreciated I have illustratedfin the accompanying drawings an embodiment of my invention. Y
Figure l represents a side elevation of a freight or boX car equipped with my locking mechanism showing the door locked, and'Fig. 2 represents a similar view with the doorlopen, illustrating the manner of securing the door when open` In the drawings: The letter A designates a portion of a freight or boX car having the usual side opening B, above and to the side of Which is secured the track C, upon which rides the rollers D, mounted in the brackets E, secured to the door F. From this construction it will be noted that the door travels upon the track to either expose or close the opening and my locking mechanism is end with the operating handle J and at itsl other vend with the head forming a pair of arms K. The lever adjacent the handle engages the spring catch or keeper L, which retains the lever against improper play or movement and to lock the lever to the door I use a hasp or similar lock M, which can only be locked and unlocked by the proper and authorized person. To the end yof each armis secured one end of the pair `of vertically disposed rods N, whose other ends are connected to the pair of short links O, which pairs of links are pivoted at O, to the inner ends of the upper and lower pairs of levers P, which are fulcrumed or pivoted at Q upon the-door, and to the vouter ends of the said levers are connected one end of the bolts or locking pins R, disposed vertically with reference to the door and pairs of levers and retained in proper position by means of the guides S secured upon the door. l p
From this construction it will be seen that the door may be moved to open or close the opening and that rocking or turning the'lever through its connections the locking bolts are moved up and down and when the door is unlocked the bolts are engaged and retained by theupper keepers T, formed on the brackets T, secured to the car and by the lower keepers U, formed on the brackets U, secured to thecar and that when the door is unlockedy and the opening uncovered the upper keepers V and lower keepers W, secured on the car, receive the locking bolts and secure the door, thus locking the door both in open and closed position to prevent tampering with the car and lock.
I claim:
In a locking mechanism, the combination with the car and door, the keepers on the car, the lever fulcrumed to the car and having a head forming a pair of arms extending at right angles therefrom, a pair of Vertical rods connected to said arms, a pair In testimony whereof I aix my signature of short links Connected to each rocl, a pair in presence of two Witnesses.
of levers Connected to each of the 'said links,
and lockingbolts connected to the outer ends FREDERICK EDWIN LEIGHTON' [1" S] of said levers and adapted to engage the tnessesz keepers on the car for locking the door when EVERETT VALLACE, opened or closed. HARRi7 FREEMAN.
