AV CORPORATION OF ILLINOIS.

BASI.

Application filed May 27,

To czZZ whom t may concer/n.'

Be it known that I, GUs'rAv A. CARLSON, a citizen 0f the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Hasps, of which the following is a specification.

his invention relates particularly to hasps for use in connection with barn doors or the like.

The primary object is to provide a thoroughly durable and secure device of this character of exceedingly simple construction which can be manufactured very cheaply. A further object is to provide such a hasp which is reversible, so that rights and lefts are not required.

The invention is illustrated in its preferred embodiment in the accompanying drawing, in which- Fig. l represents a broken perspective view of a door and door-frame equipped with the improved hasp; Fig. 2, a broken sectional view showing the door in closedV position, the section being taken as indicated at line 2 of Fig. l;V Fig. 3, a broken vertical sectional view taken as indicated at line 3 of Fig. 2; and Fig. 4, a broken edge elevational view of the door-frame, showing the keeper in elevation.

In the construction illustrated, A represents a door; A a door-frame or post; B, a keeper secured to the member A; and C, a latch device secured to the door and coacting with the keeper B.

The keeper B comprises a small sheetmetal plate having a base portion 1 provided with screw-receiving perforations and having projecting from the base portion and substantially at right angles thereto a padlock loop la. The keeper is formed by punching and shearing the metal suitably and bending the loop which is thus provided so that it will project outwardly from the base portion. The loop has the opening 2 for receiving the padlock. The loop also has a rounded outer edge lb on which the latch member is adapted to ride when the door is swung to the closedv position. At the base of the upper member of the loop is a notch or latching recess 1 which is formed by suitably notching the upper edge portion 0f the loop of the keeper, prior to the bending operation.

The punching and stamping operation is 1922. Serial No. 564,027.

so performed that the base is provided with a central projecting ear ld whose base portion is disposed between the base portions of the members of the loop. v

The latch device C comprises a mounting plate 3 and a latch-plate 4 which is pivotally connected therewith by means of a rivet 5. The mounting plate 3 is provided with perforations which receive screws 6, by

i means of which the mounting plate is securely fastened to the door. The keeper B is secured to the door jamb or frame by means of screws 7, one of which passes through the central ear ld and the others of which pass through end portions of the main part 0f the base which is disposed onl the opposite side of the loop.

In mounting the latch device the mounting-plate 3 preferably projects slightly beyond the Vfree edge of the door, as shown `in Fig. l. At the projecting end of the plate 3, a small outturned central lug 8 is provided. This lug works in a vertical slot 9 with which the latch-plate 4 is provided, so Athat the latch-plate will be supported in the positionshown in Fig. l, but will be free to rise when the latch rides .over the keeper.

The latch-plate 4 is further provided with a projecting end portion 4a which has therein a vertical slot 10 which is adapted to embrace the loop 1a of the keeper. When the door is swung to the closedposition, the upper end wall of the slot 10 rides on the curved outer edge of the loop l and drops into the notch lc. When the door is in the closed position, with the slot l() receiving the loop of the keeper, a padlock may be inserted through the loop.

The mounting-plate 3 is secured to the door before the latchsplate is swung to a position substantially parallel with the mounting-plate. The lock 8 projects only a small distance from the outer surface of the mounting-plate, so that the latch-plate 4 may be forced over the lock, the latchplate springing sufficiently to permit this to be accomplished. The lock 8 will then' serve as a stop, limiting the downward swing of the latch-plate with relation to the mounting-plate.

The latch-plate 4 is equipped with a nger piece or handle l1, the stem 1lEL of which extends freely through a slot l2 in the mounting-plate 3 and through a perforation in the door. Thus, the latch may be lifted from either side of the door. The stein portion of the finger piece ll is driven tightly into a perforation or small slot With which the latchplate 4 'is provided.

The improved device, by reason of the fact that it is formed from sheet-metal, the members lying for the most part in a single plane, can be cheaply manufactured, readily assembled, and shipped in very compact forni. It Will be understood that the linger piece may be driven through the latch-plate d after the latch device has been applied to the door. The screws 6 ofthe mountingplate are covered by the latch-plate; and the screws 7 of the keeper are also covered by the projecting end of the latch-plate, so that vwhen the latch-plate is locked to the loop of the keeper by means of a padlock, the ydoor is securely fastened and the screws can not be removed.

The latch device may be used at either vertical edge of the door andthe same is true of the keeper. If, for any reason, it is desired to use the device in such manner that it Will not latch, the keeper may be reversed and the rounded lower outer edge of the keeper will then afford a surface on which the upper Wall of the slot 10 can ride When'the door is closed, but the door Will not be latched. This is sometimes desirable Where a spring is employed for closing the door and the door is to be opened frequently.

The improved construction is simple,I can be manufactured very cheaply, and is thor` oughly effective for its purpose.

What I regard as new, and desire to se` sure by Letters Patent, is-

1. A device of the character set forth, comprising a sheet-metal keeper punched, sheared, and bent and affording a base portion provided with a projecting central screw-receiving ear and a padlock loop projecting at right angles to the base portion, the base portions of said loop flanking the base portion of said ear and the upper edge of said loop being provided with a. recess; and a pivotally mounted latch-engaging member having its free end portion provided with a transverse slot adapted to receive said'padlock loop, the end Wall of said slot serving to latchingly engage the recess of said keeper.

2. A device of the character set forth comprising'a sheet-metal keeper punched, sheared and bent and affording an attaching base provided With a central projecting ear and a padlock loop Whose base-portions iiank said ear, said loop having its upper edge provided at its base portion with a latch-engaging recess; and a coacting latch device comprising a mounting-plate, a latchplate pivotally connected With said mounting-plate and having a projecting end portion provided with a transverse slot Whose upper end wall is adapted to yride on the loop of said keeper and latchingly engage the recess at the base of said keeper, and a finger piece secured to said latch-plate and eitendingfreely through an opening in said mounting-plate.
