DOORSTOP Filed Sept. 11, 1934 Inventor m :07; m 2am,

Attorney Patented Sept. 24, 1935 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to a door stop, the general object of the invention being to provide means for preventing slams of doors without preventing the door from fully closing by providing 5 a resilient cup-shaped member and a plug, one attached to the door frame and the other to the door so that the plug will enter the cup-shapedmember when the door is closed, whereby the slamming of the door is prevented, with means 10 for preventing a vacuum occurring between the parts which would render the door hard to open. This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be herein- 15 after fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein 20 like characters denote like or corresponding parts throughout the several views, and in which:

Fig. 1 is a view of the upper portion of a door frame and door showing one of the devices in use.

Fig. 2 is a section on line 22 of Fig. 1.-

. 25 In this drawing, the letter A indicates a part of the door frame and the letter B a part of the door. In carrying out my invention, I provide a substantially cup-shaped member I of rubber or the like which has its bottom part connected to 3 the door by a screw 2. The side walls of this member gradually decrease in thickness and its outer open end is flared as shown at 3. The plug 4 is tapered from its free end to its other end, said other end being the larger, said larger end being 35 formed with the base 5 which includes the two vertically arranged parts 6 extending in opposite directions and the part I which extends at right angles to the parts 6 and is connected with the central portion of the large end of the member 8. 40 The outer edge of this part 1 slopes upwardly and inwardly towards said member 4 and this member 4 is formed with a chamber 8 which opens out through the small end of the member and a passage 9 connects the inner end of the chamber with 5 the atmosphere by passing through the reduced part of the portion 1. The parts 6 and l are provided with holes for receiving screws [0 or the like which fasten said parts to the door frame.

As will be seen just before the door reaches closed position, the plug 4 will enter the member l and the frictional engagement of the two mem- 5 bers will check the closing movement of the door and prevent it from slamming. By providing the chamber 8 and passage 9, a vacuum will be prevented from occurring in the parts so that the door can be readily opened. 10

I prefer to use two of these devices on each door, one adjacent the top thereof and one on the lower part of the door.

It is thought from the foregoing description that the advantages and'novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the app-ended claims.

I claim:

1. A door check comprising a substantially cupshaped member of resilient material adapted to be attached to a door at its closed end and having its open outer end flaring, the walls of said member gradually decreasing in thickness from its closed end to its outer end, a plug of resilient material formed with a base adapted to be attached to the door frame, said plug tapering from its attached end to its free end and having a chamber therein opening out through the small end and a passage connecting the chamber with the atmosphere.

2. A door check comprising a hollow member of resilient material closedat one end and its other end open, the closed end being adapted to be attached to a door, a plug of resilient material formed with a base adapted to be attached to a door frame, said plug tapering from its attached end to its free end, the plug entering the hollow member when the door is closed, said plug having a chamber therein opening out through the small end and a passage connecting the chamber with the atmosphere.
