I '0 all whom it may concern:

Be it known that 1, CHARLES E. WADE, citizen of the United States, residing at Masonville, in the county of Delaware and State of New York, have invented certain new and useful Improvements in Deer- Catches, of which the following is a specification.

This invention relates to improvements in door catches, more particularly to devices of this character adapted to be employed in connection with screen doors to temporarily hold the door in closed position, and has for one of its objects to improve the construction and increase the efficiency and utility of devices of this character.

Another object of the invention is to provide a simply constructed device which will automatically engage the door with sutlicient force to hold the same closed against normal pressure such as that produced by the wind, but which will yield to abnormal strains when the door is to be opened.

Another object of the invention is to provide a simply constructed device with which a hook may be coupled to lock the door in closed position.

With these and other objects in view, the invention consists in certain novel features of construction as hereafter shown and described, and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention, Figure 1 is an elevation of a portion of a door and casing and a portion of a screen door viewed from the interior, with the improvement applied; Fig. 2 is a transverse section on the line 2-2 of Fig. 1; Fi 3 is an enlarged elevation of the improved device with a portion of a door frame and casing, and with the door partly open and in section; Fig. 4 is a section on the line 41 of Fig. 1 with the door in the act of being closed; Fig. 5 is a view similar to Fig. l with the door closed and the locking hook applied; Fig. 6 is a perspective view of the improved attachment disposed in withdrawn or inoperative position.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device is designed more particularly for a screen door to automatically engage the same and hold it yieldably in closed position, but which may also be japplied to doors of other kinds, and likewise to transoms, cupboards and similar de vices, but for the pin-pose of illustration is shown applied to a screen door represented conventionally at 10 and to the jamb represented at 11 and between the screen door and the ordinary door represented at 19.

The improved device comprises a base 13 having outwardly directed sides l t-15 spaced apart. The member 13-1l15 is constructed from a single new of sheet metal, preferably plate steel, out into shape by suitable dies or presses. One of the sides, for instance the side lat, is provided with a reinforcing lip 16 bent over into parallel relation to the adjacent side. The sides L1 15, together with the reinforcing lip 16, form supporting ears through which a swinging arm is pivoted. The arm is formed of a single piece having a U-shaped or crank portion 17 and a pivot 18 extending through the ear 1-1- and directed laterally at the opposite side as shown at 19 and pivoted through theother car 15 and the reinforcing lip 16. The portion 17 is thus in the form of a crank which is free to swing upon its pivots 1S-19 between the sides 1 l-15. At its outer end the portion 19 is extended in parallel relation to the member 14 in the form of an arm as shown at 20. and bent into a loop '21, and with an eye 29. at the inner end of the loop. The eye 22 is located in close proximity to the portion 19, as shown. The base 13 is provided with spaced clefts at its rear end whereby a tongue 23 is released and bent up to receive one terminal 24; of a spring 25, the opposite terminal of the spring being coiled around the central portion of the crank 17 as shown at '26. The central portion of the member 17 is depressed slightly to receive the terminal. coil of the spring and prevent the latter from slipping sidewise. The pivots f.l-----lf) are located at some distance from the base 13 so that when the crank portion 17 is turned into its forward position as in Fi 3-4: and 6, the strain will be applied to the crank 17 below the pivots, or between the pivots and the base 13 so that the loop 21 will be locked yieldably in its forward position, and can be released only by outward movement of the arm 20 against the resistance of the spring 25. \Vhen the member 9 0 is thrown outwardly beyond the line of the pivots 1S---19 the spring will throw the arm 20 to the rear as shown in Fig. 5, the object to be here r explained. The base 13 with its attachments, will be secured to the jamb 'll of the door.

Attached to the screen door 10 is a staple device 27, the staple being designed to engage against the outer end of the smaller loop 22 as the door is closed and displace the arm 20 and move the spring 25 out of its locking position and cause it to throw the longer arm 20 outwardly and through the staple, shown in Fig. 5, and hold the door yieldably closed. The spring 25 will be of sufficient strength to hold the door closed against ordinary pressure such as that exerted by the wind, but will yield and permit the door to be opened when a relatively strong pulling force from the'outside or a pushing force from the inside is applied to the door. Vhen the door is thus forcibly opened, the outward movement of the staple 27 will throw the longer arm :20 outwardly and into the position shown in Figs. 3 and 4%, thereby distending the spring 25 and causing it to lock the longer arm in outward position, as before described, and automatically setting the device ready to be again engaged by the staple 27 when the door is again closed. It will thus be noted that it is not necessary to manually manipulate the parts either in closing or opening the door.

A 11001; 28 is connected by a screw eye 29 to the jamb 11 in position to be engaged in the loop 21 when the door is closed, as shown in Fig. 5. By this means the door may be positively locked in closed position when required. 7

The staple 2'? is preferably provided with inwardly extending lateral eyes 30 to receive holding screws whereby the staple is secured to the door. The staple 27 is likewise provided with a roller 31 to reduce the friction between the parts and cause the device, to operate with greater ease.

Having thus described the invention, what is claimed as new is:

1. In a device of the class described, a member having an eye at one end and adapted to be pivoted at the other end to a stationary support and provided with. a'lateral extension spaced from its pivot,'a trip device including a loop and adapted to be connected to a movable support, a spring operating to yieldably maintain said extension In the path of said trip device and likewise operating to maintain said pivoted member in yieldable engagement with the trip device and extending through the loop of the same, and a locking device adapted to be connected to a stationary support in'position to engage the'eye of the pivoted member. j

2. A device of the class described comprising a base having outstanding ears with one of the ears bent over upon itself and with perforations through the ears and likewise through thebent over portion, a member mounted for rotation through'said ears and the bent over portion thereof and formed into a crank between the ears and into having a lateral arm externally of the bent over portion and extending in parallel relation'to the crank, said arm having a lateral extension spaced from the crankedmember,

a trip device adapted to be connected to a movable support and in position to engage the lateral extension, and a spring connected respectively tothe crank and to the base and operating to hold the arm yieldably in its projected position and likewise to hold the arm in its withdrawn position.

3. A support adapted to be secured to a stationary structure, an arm pivoted at one end and having a lateral projection between its free end and its pivoted end, a spring connected to said support and to said arm and operating to yieldably maintain said arm in both open and closed position, a member having a transverse openmg and adapted to be connected to a movable structure and engaging said lateral promotion to swing the free end of said arm through the opening in the movable member.

In testimony whereof I atlix my signature in presence of two w1tnesses.
