DOORQCHECK.

SPECIFICATION forming part of Letters Patent No. 463,813, dated November 24, 1891. Application filed June 19, 1889. Renewed July 16, 1891- Serial No. 399,6;73. (N model.)

To all whom it may concern:

Be it known that LANSEL W. PAINE, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Door-Checks, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of my invention is to make a cheap and efficient door-check that shall pre- IO vent the door from slamming when it is closed by a spring or otherwise; and it consists in suspending to the door-post an elastic bulb in such relation to the door-jamb that the door in closing will first hit the said elastic bulb I 5 and thus be greatly checked and prevented from coming in violent contact with thejamb and making anoise, yet after the bulb has first checked the motion of the closing door it, under the continued pressure, will graduzo ally turn and roll away from the edge of the door and allow it to gently close Without noise.

My device is shown in the accompanying drawings, in which Figure 1 is a frontelevation showing apart of a door with one of my checks attached. Fig. 2 is a horizontal section showing the door in the position it occupies when it has first hit the elastic bulb. Fig. 3 is a horizontal section showing the door in the position it occupies just after the bulb has turned away and has left the door free to gently close.

In the drawings, A represents the doorframe and A the jamb, and D the door, one

of its hinges being shown at H, Fig. 1. In

Fig. 1 I have also shown a spring S, of ordinary construction, for closing the door.

My device consists of an elastic bulb B, which may be of any suitable shape, size, or form. .For illustration I have takenahollow 4o conoid. This bulb is suspended from a bracket H by link C, or by any suitable device. The elastic bulb is sohung in relation to the 'door-jamb A that as the door closes its whole impact comes upon the bulb B (see 5 Fig. 2) and is thus checked and prevented from slamming; but the bulb will gradually 'yield to the pressure of the door and will turn away from the position indicated by dotted lines in Fig. 3 to the position indicated by full lines in that figure. Then the door can gently close.

I claim A door-check consisting wholly of an elastic bulb B,so suspended that it may freely swing 5 bodily out of the way as the door is opened, then to swing back to such a position that the door in closing will be temporarily checked by it, and then under the continued pressure of the door be forced to turn away and allow the door to close, substantially as described, and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, on this 15th day of June, A. D. 1889.

ANSEL W. PAINE.
