SPECIFICATION forming part of Letters Patent No. 777,135, dated Decembei 13, 1904. Application filed May 24, 190 1. Serial No. 209,490. (No model.)

To all 1072 0772, if; n'tmg concern:

Be it known that 1, 07am G. PARsoNs, a citizen of the United States, residing at Edina, in the county of Knox and State of Missouri, have invented a new and useful Barn-Door Bolt and Lock, of which the following is a specification.

This invention relates to door bolts and locks, designed particularly for use upon barndoors.

The objects of the invention are to improve, simplify, and strengthen the construction of such devices; furthermore, to increase their ease and efliciency in operation.

With these objects in view the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described with reference to the accompanying drawings, forming part of this specification, wherein Figure 1 is an elevation of a door with the improved device applied. Fig. 2 is a vertical section at a right angle to Fig. 1. Fig. 3 is a detail perspective view of the locking-bolt, and Fig. 4 is a similar view of the slotted plate.

The reference-numeral 1 indicates a door, and 2 the frame thereof. Upon the frame 2 is a bracket 3, a staple 4 being placed upon the door.

The improved bolt and lock comprises a plate 5, which is formed with an angular slot 6, having a horizontal portion opening at each end into a vertical portion. The plate 5 is fastened upon the outside of the door 1 in any suitable manner, a slot 7 similar to the slot 6 of the plate being formed in the door. Upon the plate 5 are two brackets 8, in which slides a' bolt 9. The ends 10 and 11 of the bolt are bent outwardly. At its center the bolt 9 is formed with a downwardly-extending loop 12. Fastened between the ends of the loop 12 is a lateral extension 18,which projects rearwardly through the slot 6 in a horizontal plane, as shown at 14, and is then bent upward at a right angle to form a vertical handle portion 15, that is parallel with a line drawn longitudinally through the loop 12. In practice the bolt 9 is preferably formed of rod metal bent intermediate its ends to form the loop, the handle 15 being welded or soldered between the ends of the loop. The loop is adapted to lit over the staple t when the door is fastened and to be held thereon by means of a padlock or other suitable means.

The operation of the llnIHOVGCl device will be understood from the foregoingdescription in connection with the drawings. By lifting up the loop 12 from the outside of the door until it is in a horizontal position or by pushing down on the handle 15 at the inside of the door until its horizontal portion 14 is disposed vertically downward and its vertical handle portion becomes horizontal the bolt 9 may be slid into or out of engagement with the bracket 3.

The loop or extension 12 is heavier than the extension 13 and acts as a gravity member to maintain the handle 15 normally in raised or vertical position. Whenever the extension 13 is in the horizontal portion of the slot 6 in the plate 5, it is impossible for the loop or gravity member to descend into a vertical position; but when said extension 13 reaches the vertical leg at one end of the slot the gravity member descends and the bolt is locked against longitudinal movement.

The bent end 10 of the bolt 9 serves to engage the bracket 3 when the door is locked. The movement which carries the loop 12 from a vertical to a horizontal position carries the hook 10 from a horizontal to a vertical position, whereby it can slide through the bracket 3, which is elongated in a vertical direction for this purpose. The hook 11 by abutting against the adjacent bracket of the plate serves to hold the bolt in position.

The device of this invention is strong, simple, durable, and inexpensive in construction, and thoroughly ellicient in operation. In its novel combination and arrangement of parts and in its details of construction it presents an improvement over for a similar purpose.

Changes in the precise embodiment of in vention, illustrated and described, may be made within the scope of the following claims without departing from the spirit of the in- 'vention.

It will be observed that the loop 12 and porprior devices intended tion 15 of the bolt or locking member form grip or handle portions, Which are disposed on opposite sides of the door and which lie normally flat against the door. Furthermore, it will be observed that While the grip or handle portions are flat against the door the bolt is locked securely against longitudinal movement and that the bolt can be operated only when the grip portions are moved away from the door.

1 claim 1. A revoluble and longitudinally-movable bolt, and a pair of oppositely-directed handle members extending therefrom.

2. A revoluble and longitudinally-movable bolt, and a pair of oppositely-directed handle members extending therefrom, one of said handle members being heavier than the other.

3. A revoluble and longitudinally-movable bolt, a pair of oppositely-directed handle members extending therefrom, and means for locking one of said members.

4. A locking device having a longitudinallymovable bolt formed With lateral extensions at right angles to each other, and a handle portion on one of the extensions parallel with a line drawn longitudinally through the other.

5. A locking device having a longitudinallymovable bolt provided With a gravity member, and a handle portion, said gravity memprovided With grip or handle portions disposed flat against opposite sides of the door, and means to lock one of the handle portions.

8. A door-locking device having a locking member provided With grip portions disposed flat against opposite sides of the door, said locking member being capable of operation only When the grip portions are moved away from the door.

In testimony that I claim the foregoing as my own 1 have hereto affixed my signature in the presence of tWo Witnesses.
