Description
ZEMAN CAR LOCK June 26, 1923.
Filed Jan. 26, 1922 Patented June 26, 1923.
iJNITEo STATES PATENT OFFICE.
FRANK ZEMAN, OF LITTLE FALLS, MINNESOTA.
CAR LOCK.
Application filed January 26, 1922 Serial No. 531,841.
To all whom it may concern:
Be it known that I, FRANK ZEMAN, a'citizen of the United States, residing at Little Falls, in the county of Morrison and State of Minnesota, have invented certain new and useful Improvements in Car Locks, of which .20 combination and arrangement of parts which will be fully set forth in the follow ing specification, claimed, and illustrated in the accompanying drawing, in which,
Figure 1 is a perspective view of a frag- 2 ment of a freight car showing the lock in use Figure 2 is aside view of the lock showing the cover plate removed and illustrating the kee er in section, I
' igure 3 is a sectional view taken on line 3-3.of Figure 2, Figure l-iS a side view of Fi ure 3.
Referring to the drawings, in detail the numeral designates the lock casing poinprising abase plate 11 formed along its marginal edges with flanges 12 having screw receiving openings therein for the reception of the screws13 by means of which the cover plate 14 is securedin place. An end flange 15 connects the ends of the side flanges 12' and effectively closes one end of the casing 10 while the opposite end is open. The base plate 11 and cover plate 14 are each provided with projecting guides 16 between which the free end of the locking hook operates. y
I .Formed in the plates 11 and 14 respectively are openings 1? and 18 and pivotally mounted in the opening 17 is the trunnion 19 of a barrel 20 having radiating therefrom the operating cam 21. rectangular extension 22 projects longitudinally from the barrel 20 and enters the opening 18.,to a point in a plane with the outer side of the plate 14. Pivotally mounted at 23 between the plates 11 and 14 is the locking hook 2 1, the free end of which is operable between the guides 16 and is provided with an angular extension 25 forming a shoulder for engagement behind the keeper 26 which is secured to one of the door elements. In order to normally hold the hook member in locked position a leaf spring 27 is secured within the casing 10 and tends to urge the hook member upwardly. j
To provide for holding the lock in open position against the tension of the spring 27, a notch is formed in the barrelfor the reception of a spring pressed pawl 28 which is mounted to slide in an opening 29 formed.
in the upper flange 12 directly above the barrel. An angular extension is formed on the lower end of the pawl 28 and is provided.
with a bevelled end 30 for engagement with the cam surface 31- formed on the end ofthe' key member 32 having a rectangular socket for the reception of the extension 22.
In operation the key is slipped over the end of the extension 22 and upon forcing the key! into the lock it will be seen that the pawl will be forced upwardly and out of the notch in the barrel so that the saine will be free to swing upon its pivot 19 thereby moving the cam 21' out of en agement with the hook member 24 thus a1 owing the same to swing on its pivot 23 and into locked position.
While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction, combination and arrangementof .parts may be made without departing from the spirit and scope of. the invention as claimed. e
"What is claimed is':.- j
A look comprising a casing, open at one end, iides on the open end of the casing, a keeper adapted to fit between the guides, a locking hook pivoted within the casing, the free end of said hook being operable between the guides and to enter the keeper, a barrel pivoted in the casing, said barrel having a notch in its periphery, a rectangular extension on the barrel, a key for engaging the extension to rotate the barrel, a cam on the barrel for engaging and moving the hook 5 out of the keeper, a spring impelled detent normally engaging in the barrel notch whereby said cam is held against the hook when in open position, means formed with said key for retracting said detent when the key is inserted, and yieldable means for urging the I hook into locking position.
In witness whereof I affix my signature.
FRANK ZEMAN.
