LATCH.

SPECIFICATION forming part of Letters Patent No. 420,586, dated February 4, 1890.

Application filed August .19, 1889- $erial No. 321,284. (No model.)

To wZZ whom it may concern; Y,

Be it known that I, ENOOH S. WHEELER,a citizen of the United States, residing at Albany, in the county of Gentry and State of Missouri, have invented a new and useful Latch, of which the following is a specification.

This invention has relation to latches for gates, doors, lids, &c.; and among the objects in view are to provide a simple and easilyconstructed automatic latch capable of engaging the catch upon a door-frame, gate-post or box, said catch being designed for the reception of a padlock or seal, and also to provide a latch adapted for engaging a stud or catch secured to the wall or other fixed obj ect when the door or lid is thrown to an open position.

With these general objects in view the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure l is a general view of a door in a closed position provided with'a latch constructed in accordance with my invention, the door being shown by dotted lines in an open position. Fig. 2 is an inner rear view of the latch plate or housing; Fig. 8, a detail of the latch detached; Figs. 4 and 5, similar details in perspective of the two catches.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 represents the housing, preferably formed of cast metal and provided at both sides with integral flanges or lugs 2, perforated as at 3, for the reception of screws a, taking into the face of the door, gate, or lid. Pivoted near the rear end and in the housing, as at 6, is the latch 7, the forward end of which proj ects through a slot 8, formed in the front end of the housing and beyond said edge, and terminates in a transversely-disposed head 9 longitudinally slotted, as at 10, said slot being transverse with relation to the body of the latch. At either side of the head are pro vided small eyes 11 for 'the connection with the terminals of suitable latch-strings 12, one

- of which has its free end passed through an aperture 12*, formed in the door above the latch, and depends upon the opposite side of the door.

13 represents a spring interposed between the upper edge of the body of the latch in front of its pivot and the housing, the tendency of the spring being to depress the latch.

14 represents a catch having the usual inclined front end 15, the notch 16, and intermediate the notch and inclined end a perforation 17. Screw-openings 18 are formed near the rear end of the said catch, by which said catch is secured at a convenient portion of the door-casing.

The door being swung to a closed position, the upper edge of the transverse slot of the latch abuts against and rides up the inclined front end of the catch, and when beyond the notch drops into the same and is made fast. If desired, a padlock may be connected with the opening 17 of the catch and prevent the withdrawal of the latch from the catch, or a seal-wire may be employed in instances where my invention is applied to crates, boxes, &c.

20 represents a second catch secured to the wall or gate-post at the opposite sides of the door or gate, and is provided with the opening 21, through which a screw is passed, said catch being for the purpose of engaging the transverse slot of the latch when the door is swung to an entirely open position.

Having described my invention, what I claim isv 1. The combination, with a door, of a housing secured thereto, a spring-actuated latch pivoted therein and terminating at its front end and beyond the housing in a head having a vertically-disposed slot, and a catch mounted in a door-casing and one in the wall and both in line with the latch, the latter catch having a plain upper edge and adapted to engage the latch merely by friction, said latch being designed to engage either one in accordance with the direction. in which the door to which it is secured is swung, substantially as specified.

2. The combination, with the door having a perforation, of a housing located below the perforation and provided with lateral perforated securing-ears, screws inserted through the cars into the face of a door, a latch. pivoted at its rear end in the housing and proj ected through a slot in its edge and termi nating in a transverse vertical slot, and sta ples mounted in. opposite edges of the latch,
