Specification of Letters Patent;
ratented May 29, 1906.
Application filed January 2, 1906. Serial No. 294,209.
To all whom it may concern:
Be it known that 1, JOHN A. LOFTIN,a citizen of the United States, residing at Troy, in
the county of Montgomery and State of North Carohna, have invented certain new and useful Improvements in Hasp-Locks, of,
which thefollowing is a specification.
The ob ect' of my invention is to provide an improved hasp-lock which will embody novel and useful features of construction whereby the hasp may be securedto a staple without resorting to .the common form of peg or sta le latch and which embodies means where y a door or the like may be readily and expeditiously locked by the useof a hasp and staple.
For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a perspective view showing the Fi 2 is a face viewthereof with the outer plat e removed. Fig. 3 is a perspective view of the ring-like latch employed.
Corresponding and like parts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters.
Referring to the drawings, the numeral 1 designates the hasp proper, and 2 the staple. The hasp in the present instance. consists of the ordinary plate-like structure, provided with a staple-receiving slot or eye 3, with the exception that it is circularly widened near the staple-receiving portion and is provided with an upright or perpendicularly-extend ing flange 4, which forms the side walls of a casing for the lock mechanism. This casing is closed at its top by a plate 5, screwed or riveted on the said flange 4 and provided with an opening 6 for the accommodation of a latch-actuating handle and with a keyhole 7. The outer end of the casing-that is, the end adjacent the staple-receiving eye 3-is open at opposite ends, the said opening being constituted by cut-away portions 4 in the portion 4* of the flange 4, and said cut-away portions or openings provide passages for the latch 8. As shown best in Fig. 2, the outer portion 4' of the flan e 4 extends at right angles to the length of the hasp and at right angles to the eye 3 to form a stop or limiting means for the latch hereinafter described.
the outer the rear of the The latch 8,as shownin the drawingsmonslsts of a ringror band a portion of which is .cut away, as indicated at 8, and this cut away portion is preferably of a width corresponding tothe width of the eye 3. The band 8 is provided with an inwardly-extending radial arm 8 which is pivotally mounted at its inner end to the hasp 1, the means of pivoting. consisting inthe present instance of a shank 9 on the latch-operating handle ,9, which is inserted through the opening-6 in late, through a corresponding opening in t e arm, and through a-registering opening in the hasp 1. Thelatch-operating .handle 9 is preferably formed at its outer on for a convenient finger-hold, as shown. By
means of the pivotal mounting of the ringlike latch 8 the same may be turned within the casing of the hasp so as to bring its cutaway portion 8 in registry with the eye 3 of the hasp, and when in this position it is manifest that the eye may be inserted over the staple 2.
To secure the hasp to the staple, it is only necessary to turn the latch 8 until either end formed by the cut-away portion 8 extends through the staple, when the hasp will be secured to the staple, as is evident. In the present instance the radially-extending arm 8 of the latch is so positioned with respect to the same that it serves as a limiting means for the movement of the latch in one direction in connection with the portion 4 of the flange 4 when the cut-away portion 8 or band is in registry with the staple-receiving eye 3. Hence in the present construction the latch can be turned in only one direction to insert one of its ends in the staple. Now in order to lock the latch with its end extending through the staple so as to securely hold the hasp in place and the door or other part locked I have rovided in the lock-casing at fatch a tumbler 10, which is so mounted between studs 11 that it can shift or reciprocate toward and from the latch 8 and which is provided with a beveled surface 12 in registry with the keyhole 7. The tumbler 10 is springrojected toward the latch by means of a eaf-spring 13, one end of which is seated in a small notch in the casingwall and the other end of which is received in a slot in the tumbler. The tumbler 10 is provided at its outer end with a notch or shoulder 14 at one side, which when the tumbler is projected toward the latch will spring under one of the ends formed by the cutlatch in its circular movement.
From the foregoing description, in connection with the accompanying drawings it will be seen that I have provided an 1mproved construction of hasp in which the atch not only forms a permanent part and is thus not liable to belost, as are the ordinary peg: usually employed, but which may also be 00 ed in its closed position and prevent the unlockin of the door or the like to which my improved hasp is connected except by the proper manipulation through the instrumentality of a key acting upon the tumbler 10.
Having thus described the invention, what is claimed as new is- A hasp provided with a staple-receiving eye and with a perpendicular flange the outer portion of which extends transversely of the hasp and is provided with cut-away porwardly-extending arm of the latch that the opening will register with said eye When'said arm contacts with the above-mentioned portion of the flange, means for turning said latch whereby to project it across the eye and a spring pressed tumbler bearing against said latch and tending to enter the said opening therein.
In testimony whereof I affix my signature in presence of two witnesses.
