No. 586,663. Patented July 20, 1897.




SPECIFICATION forming part of Letters Patent No. 586,66 3, dated July 20, 1897.

Application filed June 18, 1896.

T0 aZZ whom it may concern.-

Be it known that I, RICHARD W. HUBBARD, of Ashtabula, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Hinges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in hinges, and more particularly to that class known as door and gate hinges, the object being to provide a simple, cheap, attractive, and durable hinge adapted to be secured in position without the use of screws, whereby the cost and time necessary in hanging doors, gates, and the like is greatly reduced.

'With this end in view my invention consists in certain novel features of construction and combinations of parts, as will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a View of my improvement. Fig. 2 is a view in horizontal section, showing the method of securing the hinge in place. Fig. 3 is a detached view, and Fig. 4 is a view of the centering-plate.

A represents the connecting-sections or knuckles of my improved hinge, and 1 the connecting-pin by means of which said sec tions or knuckles are pivotally secured together. Each of said sections or knuckles is provided on its outer face with a projection 2, having a flat bearing-surface 3, which latter is adapted to rest squarely in contact with the outer face of the door and door-jamb, to which the hinge is secured, while the inner abutting faces of said sections are flat. Proj ectin g outwardly from each of said bearingsnrfaces 3 is a shank a, the flat face of which being a continuation of the flat surface of the adjacent connection or knuckle. The surfaces of shanks 4: are provided with one or more barbed fins 5 and a number of barbs disposed in rows, said barbed fins and barbs running lengthwise said shanks.

As indicated in Fig. 2, the shanks 4 at are bent outwardly a trifle at a point adjacent to the pin 1, so that while their inner or flat surfaces are parallel when the hinge and door to Serial No. 596,985. (Nomodel-l which it is secured are closed at the same time a narrow space intervenes between them. The object of this construction is to prevent the door from binding on the doorjamb, or vice versa, which so often results from swelling or shrinking of the parts or in consequence of painting.

B is a centering-plate adapted to be placed between the shanks of the hinge, where it just fits, when the hinge is driven into the hole formed to receive it in the door and doorjamb.

Each section or knuckle is provided with a stop 6, adapted to limit the outward movement of the article to which the movable section is attached when said article is opened or moved sufficiently to bring said stops in contact with one another.

To apply hinges of the construction above set forth, it is first necessary to determine at what points on the door and door-jamb, respectively, the hole or recess for the reception of the shanks at is to be bored. Then this has been determined, the recess or hole is formed by centering the point of the bit in the crack between the door and door-jamb and boring the hole or recess so that one half of the bore will be in the door and the remaining half in the door-jamb. The diameter of the hole thus made should be equal to the diameter of the shanks i when in their closed posit-ion. Before the hinge is secured in its operative position centering-plate Bis placed between shanks at and the latter closed upon said plate, after which said shanks are placed in a position to be driven in the hole above referred to, which operation is accomplished by means of striking the hinge on the knuckles with a hammer or other instrument. During the passage of said shanks into their respective semicircular holes or recesses formed in the door and door-jamb, respectively, plate B follows the crack between said door and door-jamb and forces the shanks to adjustthemselves into their respective holes or recesses, leaving the fiat faces thereof flush with the abutting faces of the door and door-jamb when the door isin a closed position. \Vhen the shanks 4 are being forced to the'position above described, the barbed fins and rows of barbs enter the wood surrounding the semicircular recesses and lock said shanks against accidental removal. The pointed or sharpened ends of said barbed fins and rows of barbs are inclined outwardly or in a direction opposite to that taken by the shanks when driven into their operative position,and hence it will be apparent that whenever strain or a pulling force is exerted on the hinges said barbed fins and rows of barbs will engage and embed themselves firmly within the wood surrounding their respective sockets and prevent the hinge from being withdrawn from its operative position. The projections or lips 2, which firmly bear on the door and doorjamb, will also assist in preventing the accidental withdrawal of the shanks 4. It is apparent from the foregoing that but little labor is necessary to hang a door with my improved hinges and, further, the employment of screws is dispensed with, thus materially reducing the cost in material as well as for labor.

It is evident that changes in the construction and relative arrangement of the several parts might be made without departing from the spirit of my invention, and hence I would IHHB it understood that I do not restrict myself to the particular construction and arran gem ent of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hinge comprising two sections or members the shanks of which have fiat inner faces, said shanks bent outwardly so that they lie parallel and slightly placed apart when the hinge is closed, the shanks provided with finshaped toothed projections on their upper and lower edges, said fins inclining slightly outward and their teeth extending inward from the end of the shank.

2. The combination with a hinge, the sections of which are provided with a shank, of a centering-plate adapted to be temporarily interposed between said shanks,substantially as and for the purpose described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
