WILLIAM H. BRITTON, or PER INDIANA, ASSIGNOR or ONE-HALF To LEROY o.
BOWMAN, or PERU, INDIANA. Y
DOOR-LOCKING MECHANISM.
To all whom "it may concern:
Be it known that I, WILLIAM H. BRrr'roN,
a citizen of the United States, residing at Peru, in the county of Miami and State of Indiana, have invented new and useful Improvements in Door-Locking Mechanisms, of which the following is a specification.
This invention broadly relates to door locking mechanism, and provides for the locking of a door in a manner whereby the same cannot be opened by unauthorized persons without giving evidence of such fact, the mechanism being simple in construction, yet very efficient for the purpose intended.
' Other objects will appear as thenature of theinvention isbetter understood from the following detail description, when taken in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.
In the drawings forming part 'of this specificationlike numerals of reference indicate similar parts in the sevral views and wherein:
Figure 1 is a side elevation of a car body showing the door in locked position with my invention.
Fig. 2 is an'enlarged View of the forward 1 edge portion of the door, a portion being partly broken away to disclose a part of the mechanism.
Fig.3 is a sectional View taken on line 3-3 of Fig. 2. r
Fig. 4 is a similar View taken on line 44 of Fig. 2. j
Fig. 5 is a detail view of the sliding locking bar. a
Fig. 6 is a View of the actuating means therefor. The mechanism forming the subject matter of my invention is'herein shown in con- I nection with a freight car door, but it is desired to have it understood that its use is not limited in this connection, and that it may be usedwith other doors.
Referring to the drawingsin detail A indicates the body of the car, B the door, which is mounted in any suitable manner for sliding adjustment between the tracks (L The door B may be constructed from an suitable material, but is preferably made up of two metallic interfitting sections 10 and 11 respectively, whlch can be rigidly against displacement.
Specification of Letters Patent. Patented Sept. 3, 1918. I Application filed May 2 5, 1917. Serial No. 171,022.
also pivoted for vertical swinging move ment, a spring 14 being connected with said element for normally maintaining the latter elevated.
, Arranged between the respective sections of the door, is a sliding lock bar 15 of substantially rectangular formation in cross section, this bar being disposed in parallelism with the front edge of the door, and
cut away asat 16, the cut-away portion being normally disposed in a line with the opening 12. Secured to one of the door sections, is a plurality of spaced superimposed lugs 17, and a vertically disposed flange '18, which bridges the'space between the lugs, the said lugs and flanges defining with the forward edge of the section, a pocketfor the reception of a coiled spring 19. The bar 15'hasits upper end oifset as at 20. The spring 19 has one extremity bearing against said ofi'set portion, and its opposite end against the uppermost lug 17, an arrangement wherebythe-bar 15 is normally depressed. When the door is moved to its closed position, the latch element 13 enters theopening 12 and cut-away portion 16, and by reason of the fact that the spring 14 exerts an upward pressure upon the latch element, while the spring 19 exerts a downward pressure upon the locking bar 15, the latch element and locking bar are effectively maintained operatively associated with a view of holding the door in' its closed position; I
Secured to the same'section of the door that has the locking bar 15 mounted thereon, is" arm actuated sliding bolt 21 which is disposedat a right angle to the locking bar 15 and adapted to be received within an opening 22 in said bar to lock the latter The door section is provided with a key-hole slot 23 for the reception of a suitable key when it is desired to manipulate the bolt 21 either to lock the bar 15 in active position, or to release the same to provide for the sliding adjustment thereof.
Atransverse shaft 24: is journaled in the site'extremity of the shaft 2% and arranged exteriorly of the door is a lever 29 normally disposed vertically, andiwhen said-.lever is depressed, or in other Words moveddownwardly in an arc of a circle, the shaft24= is rotated in the proper direction to elevate the locking bar 15 against the tension of the spring 19, witha view of disengaging the bar 15 from the latch element 13, so that the door can be easily moved .to an opened position. moved from the lever 29, the spring 19 oper-' ates to depress the locking bar 15, thereby automatically returning the latter and its associated parts to normal position.
However when the door is in its closed.
position thelever 29 is vertically disposed in its normal position, and a hasp 3O swlngingly mounted upon the door frame is ar- ,ranged transversely to brldge, cover and The hasp 1s 7 conceal the key-hole slot .23. slotted as at 31 to recelve an. apertured lug 32 projectmg from the lever29, and subsequent to the association of these parts a pin flexible element. or 7 chain 3 L, ispassed through the lug 32 as, shown in Fig. 1. The pinv 33 manifestly maintains the lever 29 and hasp 3O relatively positioned in the manner illustrated in Fig. 1, and consequently the key-hole slot is concealed from view, and obstructed, while the lever 29'is held against movement. The pin 33 is provided adjacent one extremity, with a slot 35 through which a metallic seal 360i any suitable construction which prohibits the removal :of the key from the lug 32, without destroying the seal, and by reason of which fact the door can not be opened by unauthorized parties without affording evidence of the fact.
In practice the doorislocked in the manner described, and when it is desired to unlocktlie door, the seal 36 is broken, and the pin 33 removed from the lug-32, subsequent Copies of this patent may be obtained for live cents each, by addressing the Gommigsionerpf Patents,-.
Manifestly when pressure is re-.
33 supported from the door by means ,of ato which, the hasp 30 can be separated from the lever 29. The key actuated bolt 21 is then retracted from the opening 22 of the locking bar 15, and by moving the lever 20 downwardly, the locking bar 15 is elevated and. simultaneously moved out of engagement with the latch element 13. The door is then freetobe moved to an opened position. While it has been stated that the door is made of metal, embodyingtwo associated sections, it is to be understood that thedoor can be made from wood, in which instance the door can be properly mortised for the reception of movable elements of the mechanism such as are intended .to be carried by the door.
While I have'ghown and described What I consider the preferred embodiment of the invention, I desire to have it understood that I do not limit myself to the precise construction shown, and that such changes may be resorted to when desired as fall within the scope-of what is claimed.
What is claimed is 1. Locking means for doors comprising a vertically disposed locking bar mounted on the door for shdmg ad ustment, said bar having its opposite longitudinal edges cut away to provide openings, a latch element adapted to be received within one ofsaid openings of the bar when the door is in closed position, yieldable means normally tending to move said bar and latch element toward each other, a slidingbolt arranged,
at a right angle to said locking bar and adapted tobe received within the other, of said openings, whereby said bar and latch element are effectively maintained operatively associated, and means for effecting a release of said parts subsequent tothe retraction of said bolt. 7 v
2. Locking means for doors comprising a vertically movable lockingv bar mounted upon the door, said bar having its opposite longitudinal edges cut awayto define openings, a latch element adapted to enter one.
of said openings when the door is in closed position, yieldable means operating to hold 1 said element and bar' operatively associated,
a sliding bolt adapted to enter the other. of
said openings, a .lever, a connection between said lever and one end of said bar, for releasing the latter from said element, subsequent to the retention of said bolt, and :means for locking said lever in its normal position.
In testimony whereof I aflix my. signature.
