LOCK.

SPECIFICATION forming part of Letters Patent' No. 712,078,V dated October, 28, 1902.

Application filed May 26, 1902. Serial No. 109,050. (No model.)

.To all wiz/0m t may con/cern:

Ee it known that I, CONRAD KUEBLER, a citizen of the United States, residing at Calamus, in the county of Clinton and State of Iowa, haveinvented a new and useful Lock, of which the followingis aspecification.

This invention relates to locks or latches such as are used mainly upon barn doors, gates, and the like, and it has special reference to such lookin g or latching devices which are used for locking .the gate or door to which they are applied in a closed position and also for securing them in an open position.

My present invention consists in certain improvements in the detailed construction of the latch whereby the locking-bolt when drawn back against the tension of its spring shall be engaged bya lever,whereby it shall be held in its withdrawn position, the construction of said lever being such that when the door is thrown either open or shut it shall be actuated to release the locking-bolt, causing the latter to-engage with a suitable keeper, and thus retain the door eitherin an open or closed position. The detailed construction of the device whereby these objects are attained will be hereinafter f ully described and particularly pointed out in the claims.

In the accompanying drawings, Figure-1 is a side vview showing my invention applied to a door in position for operation. Fig. 2 is` a horizontal sectional view,with dotted lines indicating the position of aldoor and lock when the door is open, the bolt ofthe lock being shown in engagement with its keeper. Fig. 3 is a horizontal sectional View showing Vthe bolt Withdrawn from the keeper and in engagement with the lever-catch or detent. Fig.'

4 is a transverse sectional view taken on the line 4 4 in Fig. 3.

Corresponding parts in all the gures are indicated by like characters of reference.

The casing 5 of my improved lock may be struck up or formed from sheet metal or castiron, and it is provided with fianges 6 to receive the screws or fastening devices by means of which it is in practice secured in operative position. The casing 5 is provided with guides '7 and 8 for the longitudinally-sliding bolt 9, the guide 8 being in the nature of a perforated partition, through which the said bolt extends, a spring 10 being coiled upon said bolt between a shoulder 11 thereon and the said partition to force or shoot the bolt in an outward direction. The inner end of the bolt has; a transverse perforation 12, through which extends a pin 13, which forms the handle by means of which the bolt is manipulated. One end of said pin is provided with a detachable cap or thumb piece 14, interiorly threaded to engage with the exteriorly-threaded `end of the pin. The part of the said pin extending through the perforation 12 in the bolt is of reduced diameter, thus forming a shoulder 15, which abuts against the side of the bolt and prevents the pin from being drawn entirely through. By this construction the pin may be withdrawn or detached from the bolt to enable it to be passed through the slot 16, which must be formed for its accommodation in the door upon which the device is adj usted for operation. The reduced end of the pin carrying the cap 14 extends through a slot 17 in the casing 5. Theend of the pin 13 which projects through the slot 16 of the door is provided with an enlargement 18, by means of which it may be manipulated.

The casing 5 is provided near its outer end with a slot 19, adjacent to which lugs or ears 20 are formed for the passage of a pin or bolt 21, upon which the catch-lever or detent 22 is pivotally mounted. Said lever is provided near its outer end upon the side facing the bolt 9 with a tooth 23, adapted to engage with.

a tooth 24, formed upon the opposing face of the bolt and serving to restrain the movement of said bolt in an outward direction under the impulse of the coiled spring 10. The lever 22 is also provided closely adjacent to its pivy otal point with a cam-shaped projection 25, adapted to engage the opposing beveled face 'of the tube 24 'when the bolt 9 is withdrawn against the tension of the spring. The outer end of the lever 22 will thus be forced in the IOO end of the lever 22 forms a handle 27, which when the bolt is shot may lie in contact with the casing. When the bolt is withdrawn against the tension of the spring and the lever is actuated by the beveled tooth or projection 24 engaging the cam-shaped projection 25 of said lever, the handle of the latter is moved outward from the casing to the position shown in Fig. 3, the tooth 23 being thus thrown into engagementl with the notch at the outer end of the bolt and retaining the latter in its withdrawn position. It will be observed that the tooth 23 has been particularly described as being located near the outer end of the lever. This is important, because the extreme outer end of said lever must be free to engage the keeper of the bolt, as will he presently described.

The keeper, which is designated by 29, consists ot' a hasp or staple suitably secured to the door-framein a convenient position to be engaged by the bolt 9. A similar keeper 30 is secured to the wall or frame of the building in a suitable location to be engaged by the bolt when the door is thrown open.

The operation of my invention will be readily understood. The relative location of the parts when the dooris closed has been shown in Figs. l and 2. lVhen it is desired to open the door, the bolt 9 is withdrawn against the tension ofthe spring by means of the pin or handle 13, thus disengagingit from the keeper and at the same time actuating the lever 22 by the beveled tooth 24 engaging the camshaped projection 25, thus causing the tooth 23 to engage the outer end of the bolt and retain the latter in its withdrawn position. Now in case the door is thrown wide open the end or handle 27 of the lever will strike against the 'wall of the building, thus swinging the lever upon its pivot, releasing the tooth 23 from its engagement with the outer end of the bolt, causing the latter to be shot by the spring l0 into engagement with the keeper 30, and thus securing the doorin an open position. If, on the other hand, the door be thrown shut, the extreme outer end of the lever 22 beyond the tooth 23 will impinge upon the outer side of the keeper 29, thus releasing the lever and causing the bolt to be shot intoengagement with the keeper and securing the door in its closed position.

As will be seen from the foregoing description,my improved locking device is simple in construction, easily operated, is capable of being reversed or applied with equal facility to right as well as to left hand doors, it is not liable to get out of order, the operation of the lever-catch or detent is automatic, and said catch or detent is automatically released, so as to cause the bolt to be shot when the door is thrown either open or shut.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States l. rThe combination of a casing, the spring'- actuated bolt arranged slidingly therein and having a beveled tooth or projection, and a lever or catch facing said bolt and having a tooth or projection adapted to engage the front end of the bolt, substantially as set forth.

2. The combination of the casing, the sliding spring-actuated bolt having a beveled tooth and the lever provided on opposite sides ot' its fulcrum with a cam-shaft projection adapted to "be engaged by said beveled tooth,

i and with a tooth adapted to engage the latter or the outer end of the bolt according to the position of the latter, substantially as set forth.

3. The combination of the casing, the sliding spring-actuated bolt having a beveled tooth, the lever having a beveled projection on one side of its fulcrum adapted to be engaged by said beveled tooth and provided on the opposite side of its fulcrum with a tooth adapted to engage the outer end of the bolt or the tooth upon the latter, and a keeper adapted to receive the bolt and to engage the end of the lever projecting beyond the tooth thereon, substantially as set forth.

4. The combination of the casing, the sliding spring-actuated bolt having a beveled tooth, a lever having a cam-shaped projection adapted to be engaged by the said beveled tooth and provided on the opposite side of its fulcrum with a tooth adapted to engage the outer end of said bolt or the tooth upon the latter, according to the position of said bolt, and a handle formed by the inner end ot' the lever and adapted to lie in contact with the outside of the casing when the bolt is shut, and to be moved outward from the casing when the bolt is drawn, substantially as set forth.

5. The combination of the casing, the sliding spring-actuated bolt having a beveled tooth, the lever provided on opposite sides of its fulcrum with a cam-shaped projection and with a tooth, said tooth being located at a distance from the outer end of the lever, a handle upon said lever lying outside the casing, keepers adapted to be engaged by the bolt, and a handle for the latter, substantially as set forth.

6. The combination with a spring-actuated bolt, of a lever having means for engaging said bolt to retain itin adrawn position, said lever being provided with projecting parts on opposite sides of its fulcrum adapted to engage fixed points of contact and thereby to release the bolt for engagement with a keeper, substantially as set forth.

7. The combination of a casing attached to a swinging bracket, a spring-actuated bolt within said casing, a lever having means for engaging said bolt to retain the same in a drawn position, said lever being provided with projections adapted to engage Xed points of contact and thereby to release the bolt for engagement with its keeper, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
