Description

spring locking member 38 suitably secured to flange I8 as at 40. This spring locking member retains the buffer 34 and its supporting plate 22 in closed or inoperative position by engaging the notch 36 as shown in Figure 3, or in open or operative position by engaging the corner of plate 22 as in Figure 2.

It will be readily apparent that the plate and buier assembly may be pivoted with respect to frame l!! from its inoperative, retracted position, as shown in Figures 3-5 inclusive, to its operative, extended position (Figure 2) by a light push on the left side of the plate 22 at a spot suitably designated as at 31 (Figure 5). It will be noted that in operative position the lip 32 again functions as a cooperating stop member with respect to an inside edge of the frame |02.

When the door arrester is in its operative position and the door is swung toward a closed position by the usual door check or other means, the buffer 34 will engage the corner 42 of the trim of the door jamb 44 to quietly and resiliently arrest the motion of the door and prevent its latch'ing. Thus it is possible to open the door without turning the knob when both hands are otherwise engaged.

When it is desired to have a door (equipped with the present invention) close and latch in the conventional manner, the door arrester is pivoted in a counterclockwise direction from the position shown in Figures l and 2 to the position shown in Figures 3-5 whereupon the plate 22 will again be flush with the edge l2 of the door I4.

It will now be apparent that the present invention is a device of great utility, simple but rugged in structure, and highly effective in operation. Its installation in a door, jamb, etc., permits a door to be arrested just short of latching position or to be normally closed as desired by simple adjustment of the position of the lbuffer.

It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I claim:

1. A door arrester adapted to be mounted in a door for engagement with the door jamb, comprising a frame dening an aperture therein, a plate pivotally connected to said frame and closing said aperture, a buffer mounted on said plate, and means for retaining said buffer in extended or retracted position with respect to said frame, said means comprising a spring element mounted on said frame and alternately engageable with said plate and said buier respectively.

2. A door arrester adapted to be mounted in a door for engagement with the door jamb, comprising a frame defining an aperture therein, a plate pivotally connected to said frame and closing said aperture, a buier mounted on said plate, and means for retaining said buier in extended or retracted position with respect to said frame, said buler comprising a resilient arcuate cushion including a grooved portion for cooperation with said retaining means.

3. A door arrester adapted to be mounted in a door for engagement with the door jamb, comprising a rigid frame having inturned anges defining an aperture therein, a plate pivotally connected to said anges and closing said aperture, and a buffer mounted on said plate, said anges including a stop for said plate and said plate including a lip portion for cooperative engagement with said stop to arrest said plate ush with said frame when said buffer is in a retracted position with reference thereto.

4. A door arrester adapted to be mounted in a door for engagement with the door `lamb, comprising a frame dening an aperture therein, a platepivotally connected to said frame and closingr said aperture, said plate having inturned flanges, and a buier mounted on said plate and retained thereon by said flanges, said buier being movable between retracted and extended positions with respect to said frame.

5. A door arrester adapted to be mounted in a door for engagement with the door jamb, comprising a frame defining an aperture therein, a plate pivotally connected to said frame and closing said aperture, said plate having inturned flanges, a buier mounted on said plate and retained thereon by said flanges, and means for retaining said buffer in extended or retracted position with respect to said frame.

6. A door arrester adapted to be mounted in a door for engagement with the door jamb, comprising a frame defining an aperture therein, a plate pivotally connected to said frame and closing said aperture, said plate having inturned flanges, a buffer mounted on said plate and retained thereon by said flanges, and means for retaining said buier in extended or retracted position with respect to said frame, said retaining means comprising a spring element mounted on said frame and engageable with said plate and said buffer respectively.

'7. A door arrester adapted to be mounted in a door for engagement with the door jamb, comprising a frame dening an aperture therein, a plate pivotally connected to said frame and closing said aperture, said plate having inturned flanges, a butler mounted'on said plate and retained thereon by said anges, and means for retaining said buffer in extended or retracted position with respect to said frame, said buffer comprising a resilient arcuate cushion including a grooved portion for cooperation with said retaining means.

8. A door arrester adapted to be mounted in a door for engagement with the door jamb, comprising a frame deiining an aperture therein, a plate pivotally connected to said frame and closing said aperture, said plate having opposed flanges on one side, and a buiTer mounted on said plate and retained thereon by said anges, said bulier being movable between extended and retracted positions with respect to said frame, and being concealable.within the door, when in retracted position.

9. A door arrester adapted to be mounted in a door for engagement with the door jamb, comprising a frame dening an aperture therein, a plate having an inner face and an outer face pivotally mounted in said frame, said plate being of a size and shape to fit within and close said aperture, a buffer mounted on the inner side of said plate, said plate and buffer comprising an assembly; and yielding means carried by said frame for engaging and holding said plate and buffer assembly alternatively in aperture closing position and buier extended position.

V10. A door arrester adapted to be mounted in a door for engagement with the door jamb, comprising a frame defining an aperture therein, a plate having an inner face and an outer face eccentrically pivoted within the aperture of said frame, said plate being of a size and shape to close said aperture, and a buil'er mounted on one side of said plate; said plate and buffer comprising an assembly; said plate and buier assembly being adapted to be swung to buffer extended position outwardly of said aperture and to an aperture closing position whereby when in the buffer extended position one side of said plate cooperatively engages with said frame to act as a stop for said assembly.
