C. PETEWS AUTOMATIC DOOR LATCH FiledJune l5, 1921 'l i en@ liti i lith dll

To aZZwLo/m it may concern.'
vention, such will enable others skilled in the art to which it appertains tornake and `use the sanne.
rlhis invention relates to a locking@n device., and particularly to such a device adapted to be applied to a door. lllhile the invention is capable oit many uses and applications, it is most especially intended tor use on barn or stable doors, and such buildings where animals are kept. llt is well known that cows and other animals etten open locks on doors by rubbing against the door and engaping; the leek with their horns.
lt is an object oil this invention theretore to provide a lock ol' simple construction so arranged that it is practically impossible tor an animal to open the saine by rubbingv against the door or in a way to so engage the lock with her horn that the same will be opened. i
lt is a turther object of the invention to provide such a lock which can be readily locked and unlocked troni either the outside or inside ot the door.
llt is still another object ot the invention to provide the portion. et the lock on the outside ot the door with a latch rneans adapted to engage a keeper to hold the door in open position.
Yllhese and other objects and advantages ot the invention will be more fully set torth in the following description which is made in connection with the accompanying draw* inps, in which-- 4ig. l is a view in side elevation et the lock and a portion ot the door and door amb to which it is applied, certain portions lacing shown in section; i
Fig. E2, is a section taken substantially on the line S21-2 ot Fig. l; and
Fig. 3 is a view showing the latch holding` the door in open position.
lteterring' to the drawings, a portion ot the door a is shown which is adapted to close against the door janib Z5. rlhe door a is termed with an opening l eirtendinp) therethrough and a keeper member 2 is applied to the inside ot the door which has a tl lt. Eterial lilo. dTfAtlQ.
shaped portion 2 projecting inwardly in alinernent with the opening l and fastened to each side ot the same. rlhe keeper 2 also h a portion extending across the front ot *the door, as shown `in Fig. 2, and is further bent to have a portion 2" extending across the outside ot the door, which portion is provided with an aperture 2c in alinement with the aperture 'l. 'ldhe keeper is secured by the headed and nntted bolts 3 passing through the door and engaging the portion ot the keeper at either side thereof. A handle and housing member l of suitable shape to torni a convenient hand hold is secured to the outside ot the door by the lower bolt 3 and another headed and nutted bolt t5 which pisses through the saine in its upper end.
rlfhe member t has a tapped hole in its lower curved portion and a pointed member t5 has a threaded shank screwed kinto said hole and projecting; inwardly ot said handle to torni the pivot and nipportingmember tor a bell crank lever 7 which is provided with a recess at the outer side of its langle portion, which recess is adapted to receive the pointed portionot member 6. lt will be noted that the member G has a widened collar or shoulder portion adjacent the `ineinber Ll upon which the body portion oit the lever T rests rllheineinber i has one arno ezrtendinq'-` upwardly within the housing Il, which arm is bent at a slight angle toward the door at its upper end9 and said member also has an arm extending` through the aperlside oit an opening" fl "termed in the top ot member d, in which openingl the top edge ot" the vertical arm moves.
Secured to the amb ZJ is a housing1 or casn ing1 S comprising); a plate bent into lil-shape to iforin parallel side walls. ,llivets or screws 9 extend between the walls ot member 8 and the upper one oit which is shown as forming the pivot member tor a latch dog; l0 which projects troni easing' and is of hook torination and adapted to engage over the keeper 2. 'llhe trent edge et the den` l0 is formed with an inclined surface 102L forming a cam surface with which the edge oft the keeper 2 is adapted to engage when the door is moved inwardly. Rivets or screws 9** also extend between the sides ot the housing 8 and the upper of these is shown as forming a stop for the member 10. The member l0 is also provided with a projecting lip 10,b forming a handle therefor. It will be. noted that the casing 8 and the latch member lO are symmetrically formed7 and by such formation are rendered capable of being reversed and inverted so that the casing and latch dog may be used with either a right hand or left hand arrangement of the door. When the members are so inverted, the 111cm-, bers 9 and 9a shown as the lower members in Fig. l, will be used as the pivot and stop, respectively, for the member 10.
The member 4t is shown as having an upwardly projecting lip 4b adjacent the opening 4, which lip is adapted to engage with a pivoted latch on the side of the building or member adjacent to which the door moves in its open position. Such a latch is shown in Fig. `3 as the member ll provided with the opening lla, the same being pivoted for slight swinging motion to Athe plate l2 which Will be suitably secured to the side of the building or other member 13. As the door (L -moves toward the member c the latch member 4b will engage against the upwardly curved latch 11 and raise the same so that the member 4b passes into the opening 11a. The latch 11 will then drop by gravity and, if the door attempts to swing backwardly, it Will be held by engagement of the latch 4b with the latch 11.
The operation ot Ithe device will, doubtless, be obvious from the above description.
As the door swings toward the jainb, the upper edge of the keeper 2 will engage the surface 10@L and raise the latch l() and as the door moves to closed position. the said latch will ydrop into the keeper and hold the same in closed position. Such position of the keeper is shown by dotted lines in Fig. l. The normal position of the lever 7 is also shown in dotted lines in Fig. l. When it is 'desired 'to open the door from the outside, the handle will be placed inthe member 4 and the lever 7 moved toward the outer portion of said member. The lever will then be moved into the position shown in full lines infFig. l and the horizontal arms of the lever will engage latch l0 and raise the same from the keeper.
If it is desired to lock or unlock the door from the inside, the same can be done b manipulating the latch 10 by the handle 10b. By the arrangement of the keeper and latch it is `obvious that it would be practically im possible for a con7 or other animal-to engage the latch with her horn` or otherwise, 4and open the latch ordoor. The pivot construction comprising the member 6 and the recess of lever 7 avoids any danger of the lock being frozen in cold Weather, so that the lever 7 could not be moved. The manner in which the door will be held. in open position has already been explained.
From the above description it is seen that applicant has provided a simple 'torni of door latch, one which can be easily made and installed and which will have great utility for the purpose intended. The latch will preferably be made ot suitable material` which, it desired, may be ot non-corrosive character. The latch can also be made very strong and durable and is capable of application to either single, double, or sliding doors.
It will, of course, be understood that various changes may be made in the torni. details and arrangement of the device without departing from the scope ot applicants invention` which. generally stated, consists in the matter shown and described and set fort-h in the following claims.
lllliat is claimed is:
