DOOR-CLOSING DEVICE.

Specification of Letters Patent.

Patented Nov. a, 1920.

Application filed May 26, 1920. Serial No. 384,330.

To all whom it may concern: 7 Be it known that I, OHARLEY ADIER Pun vrs, a citizen of the United States, and a resident of Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Door-Closing Devices, of which the following is a specification.

' y invention relates to doors and particularly to a device for closing the doors and for maintaining the same in closed position, a purpose of my invention being the provision of a device of this character which is of simple and efficient construction and which may be readily applied to doors of the ordinary construction.

I will describe one form of door and one form of device embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings;

Figure 1 is a view showing a conventional form of cabinet having applied thereto one form of device embodying my invention.

Fig. 2 is a view similar to Fig. 1 showing the doors in open position with the parts of the device occupying a corresponding position.

Similar reference characters refer to similar parts in each of the views.

Referring specifically to the drawings and particularly to Fig. 1, G designates a cabinet such as a kitchen cabinet having doors D and D hingedly mounted thereon in the manner shown. The device embodying the subject matter of my invention comprises a shaft S rotatably supported at the under side of the top of the cabinet by a pair of brackets 15. The opposite ends of the shaft S are provided with cranks K and K each of which includes a vertical arm 16 disposed at right angles to the shaft S and a horizontal arm 17 disposed in parallel relation to the shaft S and at right angles to the arm 16. Embracing each of the arms 17 is a sleeve 18 pivotally connected to one end of a link 19.

The opposite end of the link 19 is pivotally connected to a corresponding door D or D by a bracket 20 secured to the under end of the door within a suitable recess. The shaft S is biased to a position wherein the cranks K occupy positions inclined with relation to the vertical by means of a coiled contractile spring G which is connected at one of its ends to the under side of the top of the cabinet C and at its opposite end to the arm 17 of thecrank K by means of a cotter pin 21.

In the operation of the device, the doors D and D are maintained in closed position under contractive action of the spring G, it being understood that the spring serves to bias the cranks inwardly thus drawing the doors inwardly through the medium of the links 19.

When it is desired to move the doors D and D to open position, it is only necessary to move one of the doors to such position, as by virtue of the shaft S and the cranks K, the movement of one door causes a corresponding movement of the other door. For example, when the door D is moved to the open position, the link 19 swings the crank K forwardly and upwardly thereby rotating the shaft S to cause a corresponding movement of the crank K. The crank K actu- V ates the door D through the medium of the corresponding link 19 so that the door is caused to occupy the same position as the door D. It is to be particularly noted that the doors, when in open position as shown in Fig. 2, are disposed in divergent relation to each other. WVith the doors in this position, the spring G, although exerting a rearward tension on the crank K, is ineffective to actuate the crank because of the position of the pivotal connections between the links 19 and the doors D and D, thereby allowing the doors to maintain their open positions. When closing the doors it is only necessary to manually swing one of them inwardly to a right angular position with respect to the front of the cabinet, when the spring is free to actuate the cranks to draw the doors into closed position.

Although I have herein shown and described only one form of door closing device embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

What I claim is:

1. A device of the class described comprising, a shaft adapted to be rotatably supported adjacent to a door, a crank formed on one end of the shaft, a link connected to said crank and adapted to be connected to a door, and a spring for biasing the crank in a predetermined direction.

2. A device of the class described comprising a shaft adapted to be rotatably supported adjacent a pair of doors; cranks formed on the opposite ends of said shaft, links pivotally connected to said cranks and adapted to be connected to a pair of doors,

and a spring connected to one of the cranks for biasing said shaft to a predetermined position,

3. In combination, a cabinet including a pair of hinged doors, a shaft rotatably sup-o ported at the top of said cabinet, cranks formed on the opposite ends of said shaft, links pivotally connected to said cranks and to said doors, and a spring secured to the cabinet and to one of said cranks for normally biasingthe cranks inwardlyto; cause said doors to occupy closed position, 7
