DANIEL H. STRAYER, or Los ANGELES, CALIFORNIA.
ApplicationfiledJune 7, 1921. Serial No. 475,575.
T all whom it may concern Be it'known that I; DANIEL H. STRAYER, a citizen of the United States, residing in Los Angeles, in thecounty of Los Angeles and State of California, have invented certain newand useful Improvements in Combined. Door Checks 7 and Buffers, for which the'following'is a full and complete sp'ecifi cation, referencebeinghad to the accompanying drawings;
The present: invention relates to'a device for preventing. the doorknob of a door from coming intocontact with the wall when the door is open and for preventingthe slamming ofithe door when the same is closed. 1
It is an object of the presentinvention to provide a deviceof-this character which will be cheap to. manufacture and which may be readily attached to any door, casement window or similar structure.
factu-red of pressedor stamped metal.
In order to more fully disclose'the present invention reference is had to the accompanying drawings, 1n.wh1ch the same, and
- ing through the hole 1.
Figs. 2, 3 and e show thestructure suitably mounted .uponaidoor. i
The structure as shown in Fig. 1 comprises a stamped metal piece having a portion 1 adapted to be pivotally mounted on the edgeof a door by means of a screw pass- The member 1 carries at one extremity an elongated portion 2 which is bent at right angles to the portion 1 at 3. A roller 4 of rubber or other yieldable or resilient material is mounted upon the opposite extremity of the member 1 by means of a pivot or stud 5. The elongated portion 2 has mounted at its lnner end a check buffer of resilient material 6, and carries at its outer extremity a second buffer of resilient material 7. As shown the buffer 7 is held in place by two ears of the stamp metal piece which are bent to form a retaining cup, although other forms of retaining means may be used. A notch 8 is also provided near the extremity of the elongated portion 2 which notch is adapted to cooperate with a. hook or detent member 9 for holding the door open as shown in Fig. 4..
As shown in F igs. 2 and 3, the device is Specification of Letters Patent.
the position shown in Fig. 1 shows a preferredembodiment of' COMBINED noon CHECK AN UFFER.-

pivotally attachedtothe edgeof a door, swinging window or ture, by means of a screw 10 passing through the hole 1. A washer may beprovided,-if desired, between'the. portion l'and'the door. The point of attachment of the screw is so selectedv with referencex tothe edge of the door and the size o-f member 1 that when the door is opened, thewweight ofthe elongated. portion 2 causes it to fall and to assume a normal position at and 4:; While the weight of the elongated portion 2 is sufficient in. ordinary circumstances to cause it to assume. this position, resilient meansmay be. provided to nor mally urge itintothisposition,if desired.
Ifthev door is now swungopen the resilient buffer 7 will come in contact with the baseboard, the elongated portion 2 being of-ssuch Itris a further object :toprovide a structure'of the type described which ismanu length as to prevent the. door; knob from coming intorcontact .with'thepl aster; H
Then the door is closed theroller at coming in contact with the door jamb, tilts or rocks the-member 1 about the screw 10 into I Fig. 2, causing. the checkbuffer 6jlto come incontactwith'the side of the door. tacting with thej amb and, the resilient-buffer 6 contactingwith the door cooperate to form. a resilient check or silencer thereby permitting thedoor to be closed without undue noise or slam. If desired, the check buffer 6 maybe omitted and buifer 7 be designed to function also as the check buffer when the door is closed. Both buffers 6 and 7 and the roller 4.- are fitted so as to be easily.
renewed when worn.
The notch 8 is provided near the extremity of the elongated portion 2 for cooperation with a hook or detent member 9 which is other equivalent 'struc-- a right. angle to the *planeof the door as shown in Figs. 3'
The resilient buffer i on mounted on the base-board or wall in such I manner as to hold the door open as shown in Fig. 4. This feature in combination with the door check function provided for by the resilient buffer 6 renders the invention es pecially advantageous. in the use of screen doors which are'normally held closed by means of a spring.
The device is also well adapted for use on bathroom doors where there is a tiled Wainscoting upon which it is diflicult to mount the ordinary type of door buffer. 1
While the structure is described as being constructed of stamped metal, it is obvious that the same may be cast or die formed. The stamp metal construction, however, is advantageous in that the device may be stamped complete in one piece and subse quently bent in either direction at the part 3 to fit either a right or left hand door.
The device can be made in any style or finish to correspond with the other hardware on the door.
Further modifications maybe made in the structure without departing from the spirit of the invention as set forth in the appended claims.
What I claim is:
I l. A structure of the class described comprising a member adapted to be pivotally mounted on the edge of a door and having an elongated portion normally projecting outwardly from the plane of the door, and means carried by said member contacting with the door jamb when the door is closed for pivoting said elongated portion from its normal position.
2. A structure of the class described comprising a member adapted to be pivotally mounted on the edge of a door and having an elongated portion normally projecting outwardly from the plane of the door and carrying a resilient butler on its extremity, and means carried by said member contact ing with the door jamb when the door is closed for pivoting said member from its normal position. a
3. A structure of the class described comprising a member adapted to be pivotally' mounted on the edge of a door and having an elongated portion normally projecting outwardly from the plane of the door, and a resilient roller carried by said member contacting with the door jamb when the door is closed for pivoting said elongated portion from its normal position.
a. A structure of the class described comprising a member adapted to be pivotally mounted on the edge of a door and having an elongated portion normally projecting outwardly from the plane of the door, means carried by said member contacting with the door jamb when the door is closed for pivoting said elongated portion from its normal position, and means carried by said elongated portion for yieldingly contacting with the side of the door when said elongated por tion is pivoted from its normal position during the door closing operation.
5. A structure of the class described comprising a member of stamped metal having a portion adapted to be pivotally mounted on the edge of a door, an elongated portion at right angles to said first named portion and normally projecting outwardly from the plane of the door, and means carried by said first named portion contacting with the door jamb during the door closing operation for pivoting said elongated portion from its normal position.
6. A structureof the class described comprising a member adapted to be pivotally mounted on the edge of a door and having an elongated portion normally projecting outwardly from the plane of the door, catch engaging means carried by said elongated portion near its outer extremity and means carried by said member contracting with the door jamb during the door closing operation for pivoting said elongated portion from its normal position.
In testimony whereof, I have hereunto afiiXed my signature.
