Wicks, Stamford, Conn, assignor to The Yale & Towne Manufacturing Company, Stamford, Conn., a corporation of Connecti out Application March 20, 1936, Serial No. 69,748 (Cl. 292-95) 2 Claims. This invention relates to a device for holding a door in an open position. The art of door hold ers is a very old one, and even the patented art has been very highly developed, so that there 5 are a great number of patents showing door hold ers of all types. My invention comprises an improvement, which, though quite narrow in character, is nev ertheless of considerable commercial value and 10 does present quite a forward step. The commercial development of door holders has been such that the trade has generally ac cepted the association of a door bu?‘er and a door holding hook as a working combination. To use 15 a hook alone, would permit the door to be in jured when opened against the hook or its mount ing. The door buffer protects the door from the hook, the hook being available, however, to en gage the door and hold it open when desired. A door holding hook and buffer, in the prior art, 20 usually comprises a metal buffer holder in which a resilient buffer is mounted and held, and a door holding hook mounted on an eye formed on the buffer holder. 2 Since doors are made to open to the right and to the left, it has been customary in this art to mount the eye on which the holding hook is car ried, on one side or the other of the buffer, de pending on whether or not the buffer is to be used with a right hand or a left hand door. For 30 many years door buffers and holders have been sold in this way; that is, the combination of a 3 buffer and hook, with the hook mounted either on the right or left hand side, and the trade has always ordered left hand or right hand buffers, depending on the direction of opening of the door with which a buffer is to be used. I have made a radical improvement over the prior art by mounting my hook holding eye on the upper surface of the metal buffer holding 4.0 portion, so that the hook is now capable of co operation with either a right or a left hand door. It has been found that when the hook is so mounted, it many times drops into position on the buffer when released from the door and does 45 not drop into a downward position out of the way of the buffer. I have found that by particularly shaping the upper surface of the buffer, as in the form of an inverted V, the hook when dropped on the 50 buffer will be cammed by this inverted V into a downward side position out of obstructing re lation to the buffer. This general combination, including the mounting of the hook and the guiding thereof, I believe, is a very radical im 55 provement in the art, and I shall claim it and the sub-combinations thereof broadly in the claims which are appended hereto. _ While I propose to form the inverted V on the metal portion of the buffer, or the buffer holder, it could, of course, be formed on the buffer por tion per se, as will be readily appreciated by those skilled in the art. , It will probably be helpful now to refer to the accompanying drawing for a description of a particular modi?cation of my invention. In the 10 drawing, Fig. 1 is a view showing a buffer-holder combination, with the holding hook holding the door in open position. Fig. 2 is an end view and section of the buffer and the holding hook, show ing the hook as it falls down on the buffer when 15 released from holding position on the door. Fig. 3 illustrates just how the hook is cammed into one of two side positions. Referring now more particularly to the draw ing, reference numeral I0 designates the metal 20 portion or buffer holding portion of a buffer held vby screws ll against the floor. It is possible, of course, to use a wall type of buffer in my device. In so far as my invention is concerned, it is im material whether the buffer is mounted on. the floor or on the wall. ' The screw I2 is cast integrally with the portion In with its tapered screw portion 12 within an open socket 14, into which a removable resilient buffer body I5 is inserted and preferably rotated so as to be held ?rmly by the screw portion l3 of 0 the screw l2. An eye 16 is formed on the upper surface of the buffer holder l0 and has mounted thereon a hook I‘! which may engage an eye l8 carried by a door l9. It is obvious that in this sort of ar rangement, the hook I‘! is adapted for coopera tion with either a right hand or left hand door, so that it is no longer necessary for buyers of such devices to specify right or left hand devices. In order to prevent the hook from remaining 40 on the upper surface of the buffer body I9 when it is released from the eye l8, the upper surface of the body I0 is formed with an inverted V-por tion 20 cooperable with a rounded surface on the hook I‘! for camming the hook I‘! into its full line or dotted line position, illustrated in Fig. 3. The invention will now probably be quite clear to those skilled in the art. I now claim: 1. In a combined door buffer and door holder, in which the door holder is a hook carried by means ?xed to the door buffer, and the buffer has a rubber buffer portion, means supporting said hook above said rubber buffer portion so. that said hook will have a tendency to drop there 55 2 ' 2,121,766 on when released from the door, and a V shaped said hook above said rubber buffer portion, and lug on the surface of the buffer directly under said hook for guiding said hook into a downward for directing gravitational movement of said hanging position in non-obstructing relation to the rubber buffer portion. 2. In a combined door buffer and door holder, in which the door holder is a hook carried by means ?xed to the door bu?er, and the buffer has a rubber bu?er portion, means supporting a specially shaped upper surface on the bu?‘er hook into a downward hanging position in non obstructing relation to the rubber bu?er portion 5 when said hook is released from holding rela tion to the door.
