HINGE.

SPECIFICATION forming part of Letters Patent N0. 486,952,'dated November 29, 1892.

Application filed March 16, 1892.

.To all whom it may concern.-

Be it known that I, WILLIAM SIssoN GIL- LESPIE, a citizen of the United States, and a resident of Bath Beach, in the county of Kings and State of New York, have invented certain new and useful Improvements in Hinges, of which the following is a specification, ref? erence being had to the accompanying drawings, in which- Figure lis asectional View of myimproved hinge, showing the same closed. Fig. 2 is a sectional View showing hinge open, and Fig. 3 is a plan View showing hinge detached and closed.

Like letters of reference indicate like parts in each.

My invent-ion relates to an improvement in a hinge of a kind for which Letters Patent of the United States No. 470,043 were granted to me on the 1st day of March, 1892; and it consists in providing another and more positive means 0f securing a uniformity of action between the members of one or more hinges on the same door or lid; in providinga means for keeping the crack of a door always closed against observation, no matter what the position of the door, and at the same time making a dust or practically air tight joint when the door is closed, and, further, in providing metallic stops for the different members of a hinge rather than leave this office to be performed by the hinged substance, as shown in my former patent, relation in general being to hinges incased entirely within the door and jamb and invisible when the door is closed. These ends I accomplish in the two former provisions by the employment of two ordinary [iat pin-aps B and C, with an intermediate member connecting them by means of fixed pins, said intermediate member A being formed like a rectangular letter U, with its upper ends terminating in ordinary cylindrical hinge-knuckles and having secured to its bottom part on the inside a piece or strip F of the same rigid material of which the door and jamb are composed and so formed by being hollowed out at the sides as to play or slide on contra-curved surfaces formed on the edges of the door D and jamb E, these curves Serial Nc. 425,133. (No modei.)

beingconcentricwiththepinsof saidknuckles, 5o thus maintaining a practicalcontact between the piece F and the edges of door and jamb D and E during the entire convolution of the hinge or parts thereof. A reference to the drawings will show how this piece F, secured to the member A of each hinge and working on the curved edges of the door D and jamb E, will always close the crack, connect the hinges one with another, and thus secure uniformity of operation between their sev- 6o eral parts and at the same time form a covered joint when the door or lid is closed, the piece F being so constructed as to never entirely leave the support of nor fail to support the member A or the edges of the door D or jamb E. t

In my former patent the thin lips of thedoor D and jamb E, now shown in connection with the piece F, Figs. 1 and 2, either one striking against the inside of members A, determine 7o the commencement of operation in the opposite knuckle of the-hinge, and whereas africtional resistance greater than the strength of these lips, owing to the weight of a door or other cause, Inight damage the hinged parts I have provided a stop in the hinge itself, which in the present illustration will only permit a quarter-turn of the iiaps Band C on the intermediate member A. This stop I form by makingablank ward with one-quar- 8o ter removed in the center of each knuckle. The remaining parts of said wards in iiaps B and C striking against the remaining part of the wards in member A will form a metallic stop sufficient to avoid any friction in either of the pins or knuckles and prevent any injury to the lips of door D or jamb E. (See knuckles between intermediate member A and B and member A and Hap O in Figs. 1, 2, and 3.). Of course it is understood that all of 9o the above may refer to a single hinge as well as to two or more where only one may be used or is necessary.

Having now described the improvement on my hinge, its construction and operation,`what I claim as new, and desire to secure by United States Letters Patent, is-mh In a concealed hinge, the combination of 'nwo ordinary flat pin-aps, with a rectangu- Signed at Brooklyn,n the county of Kings lar U- shaped intermediate member oonneetand State of New York, this 10th day of March, ro ing said flaps, and a strip secured to the in- A.
