' 'APPpIoATIoN FILED o'oT. 13.1998. 930,534. Patented Aug. 1o, 1909.'

I WITNESSES c, /f/ 55W/ ALVIN L. ooX, or ELIZABETHTOWN, KENTUCKY.

DooR-FsTENEn.

Specification of Letters Paten Patented Aug. 10, 1909.

Application le October 13, 1908. Serial No. 457,543.

To all whom t 'may concern.'

Be it. known that I, ALviN L. COX, citizen of the United States, residing at Elizabethtown, in the county of Hardin and State of Kentucky, haveinvented certain new and useful Improvements in Door-Fasteners, of which the following is a specification.

My invention relates to door fasteners, and the object thereof is to provide asimple and inexpensive device, which, in its operation,'

direction, corresponding tothe opening of the door, and with a locking member to lprevent rotation thereof and maintain it in engagement with the keeper.

In the accompanying drawings, illustrating my invention, and forming a part of this specification, and wherein like numerals are used to designate like parts throughout the several figures, Figure 1 is an elevation of a portion of a door and the casing, illustrating my improved fastener applied thereto. Fig. 2 is a horizontal sectional view taken therethrough. Fig. 3 1s a pcrspeotlve elevation of the fastening member', and, Fig. 4 is a horizontal sectional view through a portion of a door, and a fastener attached thereto, and -forming a slightly modified form of my invention.

In the embodiment of my invention, as illustrated in Figs. l and 2, I provide the easing A, of a door B, with a keeper l, at`

tached vertically upon the casing strip-C, against which the outer edge of the door B abuts when the sameis closed. The keeper l is of the U-shaped form, having its ends secured to the strip C whereby to hold its body portion spaced therefrom. Mounted upon the inner surface of the door B, is a rectangular frame 2, open at its side facing the vertical edge of the door, and provided with a transverse pin 3, upon which is mounted an operating member 4, extending,

outwardly through the open side of said casing, and provided with a cut out portion forming the keeper engaging fingers 5 and 6 upon each side thereof, and adapted to receive the keeper l therein when the door B is closed as' shown in Fig. 2. The casing 2 is provided with a transverse pin 7 rearwardly of the pin Blupon which the operating member 4 is rotatable, upon which pin 7 is coiled a spring 8 having one end thereof bearing upon the inner surface. of one wall of said easing and having its opposite end bearing against the rear cam,` edge 9, of

vsaid operating member 4, which edge 9, as

shown in Fig. 3, is provided with a central slot l0, to prevent accidental displacement of the end of spring 8 bearing thereupon. Thus upon the movement of the door keeper from the closed position shown in Fig. 2, the operating member t is rotated upon the pin 3, by contact between the keeper l and the engaging linger 5 thereof, against the steady tension of the spring' 8, whereby the door is prevented' from accidental opening. The opposite movement, to close the door, finds the operating member 4 in the position shown in dotted lines in Fig. 2, owing to the rotation thereof during the openino' movement, and upon engagement of the keeper l with finger 6, the rotative movement 'of said member is much quicker than the rotative movement thereof when the door is open, inasmuch as the same is locked against the tension'of spring 8. The rar cam edge of. the operating men'lber 4 is provided with av V-shaped eut out portion l1, which is adapted for the reception therein of a portion of a locking member 12, pivotally mounted upon a transverse pin 13, within the Casin .2, and extending through a slot 14 in the wall thereof, in order that the same may be pressed into engagement with the said out out portion .ll,'-"\fvhen the member 4 is in engagement with the keeper l, as shown in Fig. 2, to prevent movement thereof and lock the same and the door B. In this form of my invention, the rotative movement of the operating member l is limited in both directions, by means of a strip l5, arranged transversely between the walls of the casing 2, and parallel with the pin 3.

In the form of my invention illustrated in Fig. 4, the rear cam edge of the operating member 4 is provided with a central slot, somewhat deeper than the slot l0, to guide the engaging end of spring S, in the form shown in Figs. 1 and 3, and is further lrovided with a transverse pin 16, exten ing .through the said slot, and is adapted for a swinging locking member for engagement n within said cut out portion in one position of said rotative member to lock the same from rotative movement, substantially as described.

2. In a door fastener of the character described, a rotative operating member, and a sprintf member controlling rotative movement oisaid rotative member and constitut- 1n@ a stop to limit such movement, substantiflly as described. V

In testimony whereof I aflix my signature in presence of two witnesses.
