AUTOMATIC LOCKING DEVICE.
Specification of Letters Patent.
rammed. May 17, 1921.
Application filed August 12, 1920. Serial 110.403,163.
To all whom t may concern:
Be it known that I, CONRAD GERHARD, a citizen of the Republic of Germany, residing at Munich, lTegernseerlandstrasse 135, Germany, have invented certain new and useful Improvements in Automatic Locking Devices; and I do hereby declare the following to be a clear, full, and exact description of the invention, suchl as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters or figures of .reference marked thereon, which form a part of this specification.
Several constructions of automatic locks whichv are actuated bythe closing of the door are already known particularly in railway-cars and other vehicles.
Locks of this ltype are provided with a bolt influenced by the closing spring, which bolt is secured in the openand closedeposition by a locking lever which can be released either by hand or by closing the door.
rlhe -present invention relates to that type of locks but it differs essentially from the known locks by its lsimpler. construction, cheaper cost ofmanufacture and by its more reliable manner of working.
An essential feature of the invention consists in the provision of a releasing member which canV be raised by means of atappet or latch to actuate the locking lever securing the bolt. The end of the locking lever projects beyond the end face of the lock casing, in a known manner, into the path of a vertically displaceable gliding member in the keeper. This gliding member has an inclined face that yieldingly engages the end of the locking lever when the door is being opened but when the door is being closed the gliding member Vis in fixed position and causes a displacement of the locking lever and: a release of' the bolt. The different parts are in'such an operative engagement with each other that the lever locking the bolt may belifted by operating thetappet by hand when the door is being opened or I automatically by means of the guide piece when the door is being shut.
A preferred e form of the invention is shown on the accompanying drawing, on which:
Figure 1 shows a lock in front elevation, the cover plate being removed;
Fig. 2 is an end view of the keeper;
Fig. is a section alongy line A-B of Fig. l;
Fig. 4 shows the lock in the bolted .posi-- lever e is mounted on pivot d, and rests v against the base plate y of the lock. ySaid lever is fitted with a lug g, which according to the position of the bolt is pressed into notches z', 7a of the bolt a by the action of a spring h on said locking lever. rIhe upper edge of the bolt between the notches 11 and lo is beveled. Av releasingV member Z, mv abuts against the lug g of the locking lever, the vertical shank Z being guided in guide plates n and o fitted to the base plate 'f of the lock. Below the locking end b of the bolt a; a lug p, which may be actuated by hand for instance byV means of a latch, is turnably mounted, and can be brought into engagement with a projecting part g of the bolt a', Zr through which engagement the bolt a, b is moved in the direction of the arrow and the lock unbolted. The lug p is influenced by a spring 7 and is provided with a side with a vertically movable gliding member w guided in a slot l of the keeper and projects outside the latter forming a stop m which is arranged at an angle to the vertical. The stem y of the gliding member lw is influenced by a spring e which normally holds the stop in the path of the part u.
The manner of operation ofthe lock is as follows In the'position shown in Fig. 1 the frontv part' `of the bolt is free-of the keeper o so that the door may be opened by turning it out. The gliding member m which is situated behind the end u of the locking lever e (as is shown in Fig. 2 in chain-dotted lines) rection, in consequence of the oblique arrangement of said engaging parts into the position shown in chain-dotted lines in Fig.l
2, in which position the part u of the locking lever c is permitted to pass below the gliding member and the door can be opened, whereupon the gliding member is brought back into its normal position 'by the action oi" the spring.
Assuming now the open door to be closed, the part u is brought into engagement with the member Jfrom the opposite side. The latter part rests on the lowerend of slot l and'cannot yield, therefore the oblique part a of the locking lever glides along the obliqueiace of Amember sa whereby the locking lever e is lifted against the action of the spring it until it is tree of member x. As soon as this occurs, the locking lever c is lifted to such an extent, that its lug g disengages the notch Z3 (this position of the locking lever is shown in chain-dotted lines in Fig. l), whereupon the bolt a is driven into engagement with the keeper 'by the action of spring c and the lock and the door is bolted, which position'is shown in Fig. 4C.
The locking lever e is then pressed downward by means of the spring 7L and the lug g comes into engagement with the notchy z', whereby the bolt is secured against carrying out an undesired unlocking movement. The spring r at the same time turns the tappet 79 into its proper engaging position.' In order to unbolt the lock and open the door the tappet 79 isv turned in the direction oit' the arrow indicated in Fig. t that is in an anticlockwise direction, by means of a handle or a trigger located on the inside or outside of the door. In consequence of this turning motion the projecting part s of the tappet which rests against the shank m of the releasing member lifts the latter. The vertical shank Z` presses the lug f/ of the locking lever which is in the notch cf in an upward direction until the notch is disengaged. Upon a further turning of thetappet the latter comes into engagement with the edge (I of the bolt, whereby the bolt is pushed back in the direction of the arrow shown in Fig. l and is thus drawnout of the keeper, the lug g glides along the oblique face 2 which connects Ithe twovnotches z', 7c. As soon as the bolt is pushed back far enough for the lug g to leave the oblique surface 2, the lug snaps into the notch k, the tightened spring r turns the tappet ,19 back and all the parts are in Fig. 1.
The locking lever which can be brought out of engagement by closing the door as well as by hand by actuating the tappet secures the `bolted lock reliably againstv any undesirable openingy caused by the vibration of the vehicle, as the bolt which is inserted deeply into the keeper cannot leave the latter for these reasons. The locking lever may be so adjusted that only a slight pressure c'. c. -a very gentle closing of `the door causes its disengagement. The lock is of a fiat shape so that it does not take up much room nor requires large recesses on the door.
I claim:
l. An automatic locking device, comprising a spring actuated abolt having notches formed therein, a keeper, a spring actuated locking lever adapted to engage said notches the end of said lever projecting beyond the end cover of the lock in the direction ofthe keeper, a spring urged tappet pivotally mounted on the base plate of the lock and adapted to be turned `to cause a withdrawal of the bolt from the keeper, a releasing mem- Y ber interposed between the tappet and the lever for releasing the latter upon a turning ofthe tappet, and a .member arranged in the keeper adapted to be brought into yielding engagement with said projecting end of the lever when the door is being opened, and acte ing as a fixed guiding face which engages the end of the locking lever and releases the bolt when the door is being shut.
2. An automatic locking device, comprising a .spring actuated bolt having notches formed therein, a keeper, a spring actuated locking lever adapted to engage saidnotches, the end of said lever projecting beyond the lock casing in the direction of the keeper,
and provided with a face arrangedobliquelyengagement with the bolt upon a turning of the tappet, and a vertically displaceable member having an inclined face in `the path of the oblique end of the locking lever and displaced by the latter in a vertical direc-r tion when the door is being opened and acting as a fixed guide tace over which theface of the locking lever glides, whereby the latter is lifted and the'bolt released when the door is being shut.
In testimony that I claim the foregoing as my invention, I have signed my name.
