LOCK.

Thai? who lit it may comm Be it known that Ldoriv GILBERT, a citizen of the United States, andresident of Plant City, inthe' county of Hillsbor ough and State of Florida, have invented." certain new and useful lin farovementsin Locks, of

orthe like, and the primary object of the invention is to provide a device of this character which is" quicklyadjusted to operative or inoperativeposition, without the employment of a key; p h

Another object of the invention is to provide device of this character which is easily and simply constructed, inexpensive to manufacture, and one which will be very eflicient in operatiom With these'and numerous other objects in, view, my invention consists of the novel features of construction, combination and arrangement of parts which will be herein referred to andv more particularly pointed out in the specificationand claims.

In the accompanying drawings Figure 1 is a perspective view of the lock;

Fig. 2 is a vertical section through the same and Fig. 3 is a horizontal section.

In describing my invention I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views.

The numeral 1 designates a base plate on which is positioned a cylindrical .casing 2 having formed in its top 3 an aperture 4. This casing 2 forms a keeper for the lock. Pivotally mounted on the inner surface of the top 3 and having a handle 5 projecting through the wall of said cylinder, is a pivoted latch 6 for a purpose to be hereinafter more fully described.

The base 1 is provided with a projecting portion 7 having an aperture therethrough and disposed in alinement with said aperture and mounted on the projection 7 is a tubular casing 8 which is externally threaded as shown at 9. A supplemental internally threaded casing 10 is adapted to be cooperatively related with the said first mentioned casing, and the top of the casing 10 Specification of Lettr'slatent.

hasan aperture therethrough adapted for ali'nement with the aperture through the projection 7,, and consequent alining with the-bore of the casing 8.

The hasp lock 11,0f this device is of the usual type being provided with a main portion 12 that is positioned through the alining apertures in the casing, and projection 7 and is formed with a hook bent portion 13. The main portion 12' of the hasp extends parallel with-the keeperQ through the easings, and above and ,below the same. The lower projecting end of said main portion has a crank 14 formed therein, so that the hasp may be rotated in a manner to be hereinafter more fully described. The portion of the hasp that is positioned through the casings is slightly reduced, and a collar 15 is" mounted on said" portion of the hasp, said collar being formed with outwardly projectingfianges that are adapted to engage the edges ofthe aperture in the top of the casing 10. This connectingcollar reci-procably, but non-rotatably connects the hasp with the outer movable casing 10. The bent hook portion 13 of the hasp' 11 is formedwith a notch 16 therein for a pur-' pose to be hereinafter more fully described. In operation when the various parts of the device are positioned as shown in Fig. 1 of the drawings, when it is desired to operate this type of lock, the crank 14 is operated and this will swing the hasp 11 around until the bent portion 13 is disposed above the keeper 2, and directly in alinement with the aperture at in the top thereof. When the parts are'in this position, the outer casing 10 is rotated, the outer surface of said casing being roughened so as to facilitate this operation, and consequently the said casing will be moved down upon the inner casing 8, owing to the cooperative threaded engagement between these casings. As the main portion of the hasp 12 is reciprocably but non-rotatably connected with the outer movable casing 10, consequently upon downward movement of said casing the hasp will be correspondingly moved,

and the projecting bent end 13 will be moved down through the aperture 4 into the keeper 2. When the casing 10 has reached the limit of its downward movement, the end 13 of the hasp will be positioned within the keeper, and upon moving the pivoted latch 6 across said keeper, the latch will engage the notch 16 in the end of the hasp, and prevent accidental withdrawal thereof, should the outer casing 10 work up. To re lease the device from operative locked position, it is obvious that the outer casing 10 is merely rotated in the opposite direction,

whereupon the hasp will be adjusted longitudinally, and moved from out of engagement with the keeper. Upon operation of the crank 14 the hasp will be rotated and the bent portion will be swung out of opera tive relation With the keeper. This type of lock will form a very efiicient, and quickly operated device especially adapted for use on barn doors, warehouse doors or the like, The longitudinally adjustable handle may be quickly swung out of operable relation when it is not desired to use the device, and the various parts of said device are disposed in locked position, the pivoted latch member 6 forms a supplemental locking means to ab- Having fully described my invention,

engagement with said keeper, and a crank on the lower end of said hasp whereby the same is adapted tobe rotated out of opera tion withthe keeper.

2. A device ofthe class describedincluding a keeper, a hasp disposed substantially parallel therewith, an externally threaded tubular casing carried by the keeper through which the hasp is adapted to be slidably p0;

sitioned, and internally threaded casing cooperatively. related With the firstmentioned casing, and means for reciprocably but non rotatably connecting the, last mentioned casing with the hasp. 3. A device of the class ing a keeper, a rotatable and longitudinally adjustable hasp of a'greater length than said keeper disposed substantially parallel therewith, means for moving said hasp longitudinally whereby one end is adapted for engagementwith the keeper, meanslin said keeper for locking said end of the hasp when positioned therein,and a crank on the other end of the hasp for rotating the same when the first mentioned end is disengaged from the keeper. y

In testimony whereof, I afiix my signature hereto. i
