DOOR-CHECK.

SPECIFICATION forming part 0f Letters Patent No. 469,968, dated March 1, 1892. Application filed September 111891. Serial No. 404,404. (No model.)

To all whom it may concern.-

Be it known that I, HENRY R. FRIsBIE, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Combined Door Checks and Holders, of which the fol-A lowing is a specification. y

My invention relates to improvelnents in door checks and holders, its object being to check and break the force of a temporarilyopened door without jar or shock; also, to provide means whereby t-he door, when so required, may be retained in an open position and readily disengaged therefrom.

To this end my invention consists of two parts, one a `tapered metal thimble secured to the door, carrying a correspondingly-tapered rubber thimble whose contracted mouth is calculated to sustainand repel t-he shock of an opening door and react against a stud secured to the base-board or to expand undera greater or more potent force and hold the door open.

The invention further consists in the construction and combination of the parts, as will be hereinafter fully set forth, and particularly pointed out in the claim.

In the accompanying-drawings, forming a part of this specification, Figure l is an end elevation of a broken section of a door and base-board, also side elevation of the device attached thereto and acting, as represented,

in the capacity of'a check. Fig. 2 is a plan I, viewof the metal and rubber thimble. Fig.

3 is a sectional side elevation both of the metal and rubber thimbles through Y3 of Fig. 2 and a section ofthe stud through Y3 of Fig. l. Fig. 4 is a front plan view of the metal thimble. Fig. 5 is a sectional side elevation of said thimble through Y5 of Fig. 4. Fig. 6 is a side elevation of the rubber tip or thimble; Fig. 7, a front plan view of the same.

Its construction and operation are as follows: l represents the metal thi-mble; 2, the rubber tip or thimble placed within the one of metal; 3, the door to which the metal thimble is secured by screws et. 5 is the check or holding stud, (as the case may be.) which is secured to the base-board 6 by means of the central screw 7. S is an acorn-shaped head on the stud 5; .9,areduced portion or-neck of the stud with which the lip lO of the rubber thimble engages tohold the door open.

In the construction used heretofore it has 5 been difficult to employ an elastic device for the twofold purpose of the check and holder. If made sufficiently elastic to readily engage the stud, its holding power or grip thereon is correspondingly reduced. Increasing its hold- 6c ing power renders it liable to be detached from the door when disengaging the stud therefrom.

In my device all the elastic properties of the rubber are brought out and utilized both as a check and holdback, while no amount of pull in disengaging the stud can displace it. The metal shell or thimblel formsasolid and firm support for the thin rubber thimble or holder 2, which is correspondingly tapered 7o and placed within said metal thimble. The contracted mouth 1l (see Figs. 2 and 7) is sufficiently reduced toenable the head 8 of stud 5 (see Fig. l) to strike quite a blow and rebound therefrom when operating simply as a check; but when required as a holdback sufficient power must be applied to force the head 8 of the stud 5 into-the contracted mouth ll. As the rubber extends beyond the metal,

it will permit the mouth to expand sufficient 8o for this purpose, whereupon the rounded lip 10 will embrace the neck 12 of the stud. However rmly the lip 10 embraces the neck 9 the rubber cannot possibly be pulled out is disengaged. Therefore the holding power may be increased to any extent without such accident occurring. and the lip lO of the rubberthimble or holder 2 are so formed that the holding power is greatlyimproved, while the shoulder 12 of the stud will prevent a further entrance into the rubber thimble than is required to lock the device.

The neck 9 of the stud 'of the tapered metal thimble when the stud 85 In attaching the device the thimble portion is first secured to the door, as shown. Then the stud, which carries its own screw, is placed against the base-board and on a line with the mouth of the portion on the door. A slight blow of the swinging door will cause the screw loo of the stud to indent the base-board, at which point the stud will be secured. It 'is quite the rot'ainingring, a semi cylindrical' lip formed at the mouth of the thimblejand a stud with an entrance-edge and a shoulder adapted to pass into said thimble, substantially as and for the purposes described.
