JOSEPH NICHOLS, OF CHICAGO, ILLINOIS.

HINGE.

SPEGIFICATION forming part of Letters Patent No. 517,124, dated March 27, 1894.

Application filed May 31, 1893.

To 00% whom it may concern.-

Be it known that I, JOSEPH NICHOLS, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Hinges, of which the following is a specification. I

My invention relates especially to the class of hinges used for triple mirrors, used by gents furnishing houses, and is especially designed for use where it is desired to swing the hinged article through as large an angle as possible, and clear the post or fixture to which the hinge is fastened.

Reference will be had to the accompanying drawings in which- Figure 1 is a side vertical view of a mirror hinged to a post. Fig. 2 is a front View of one hinge and post, the mirror removed, showing the shank of the hinge in section. Fig. 3 is a top plan view of the hinge with the shank of the hinge in dotted lines, and the pivot points of the 'shank in section. Fig. 4 is a side sectional view on the line 4. 4. Fig. 2. Fig. 5 is a bottom plan view of the shank of the hinge. Fig. 6 is a side sectional view on the line 6. 6. Fig. 3.

In the drawings -A- designates a mirror to which there is attached the shanks G of the hinge, the body of the hinge D being fastened to post B. To the shank O of the hinge, there are fixed pivot pins 0 O O 0 isshorter than O and 0 for the purpose of clearing the fins D, as will be described later, and O and (l are provided with slots O to engage fins D'.

In the main body of the hinge D there is a guideway 02, which engages the pivot pin 0 during a part of the revolution of the hinge, which guideway is shaped to conform to the movement of the shank when guided by the pins 0 and 0 when in engagement with fins D', and also to guide the shank in conjunction with either pin 0 or C alone, when the same is over and revolving on the center of studs D or D until the position of the flange d or 01 is such as to hold the pin 0 or C in position without the aid of pin 0 In the body of the hinge D there is pivoted at the points at (Fig. 6) two studs Serial No. 476.069. (N 0 model.)

jections 6', e shown, in dotted lines in Figs. 2 and 3, which projections e e engage the notches e in the flange D of the studs D D Two of the notches e are shown, one is to hold the stud in position so thatthe flanges 01 d will be in line with the fins D and the other one is to steady the mirror in a position at which itis frequently used, and thus a number of, such notches may be made in the flange D to' suit the cases required. The fins D are cut away at d to permit the pins 0 (3 to pass out at the period of the revolution when one of them centers on the studs D D The operation of the hinge from the central position shown in the drawings is thus, in moving in either direction the pins C G with their slots O ride on the fins D, and the pin 0 moves in slot d, which conforms to the movement produced by the fins D, and when one pin say 0 centers over flange d of stud D as it ceases to move farther in the line of fin D, but turns on the center of stud D which move ment turns the stud also as slot 0 engages flange d and the shank C revolving on the pivot D revolves pin gagement with fins D' through the space (1 and the pin 0 clears slot d and passes out over fin D, and the revolution of the stud D prevents the disengagement of the pin 0 and the flange d of the body D sustains the outward strain of the pin 0 This is shown by the dotted position C Fig. 3. wherein 01 indicates the position of flange d Thus this hinge makes possible almost a complete revolution and at the same time clears a space wherein a post may stand to sustain the hinged article.

What I claim is 1. In a hinge the combination of the body D formed with the guideway .d, the revoluble studs D and D seated therein 0 out of ennear the inner edge and on opposite sides thereof, and the curved fins D' on its outer edges, of the shank having pin 0 to engage said guideway, and slotted pins C and C on the inner end and opposite sides of said shank to engage said fins, whereby the guideway 01, pins G fins D', pins C and C sustain and carry the shank through the central portion of the revolution, while studs D and D carry the said shank during the balance of the revolution, substantially as, and for the purpose shown and described.

2. In a hinge the combination with the body D provided with two revoluble stud pivots D D at the sides thereof, and having flanges d d of shank 0 having pins adapted to engage said studs, during a part of the revolution of the hinge, of an independent carrying device for carrying the shank of the hinge through the period of revolution, clearing the space occupied by the sustaining post for the purpose shown.

3. A hinge having a shank 0, having pins C and G at the inner end and opposite sides thereof, a body D having revoluble studs D and D at the opposite sides thereof, said pins 0 and G engaging the studs D and D through parts of the revolution of the hinge, substantially as shown and described, combined with a spring engaging locking device to hold the gaging the studs D and D through 40 parts of the revolution of the hinge substantially as shown and described, combined with a spring engaging locking device to hold studs D and D in position for the purpose described; said locking device consisting of a flange D on said studs having notches e, a spring catch E engaging said notches as shown.

5. A hinge having a shank 0, having pins 0 and G at the inner end and opposite sides thereof; a body D having revoluble studs, pivots D and D at the opposite sides thereof, and flanges (1 outside of said studs combined and arranged substantially as shown, and for the purpose described.

In witness whereof I have hereunto subscribed my name in the presence of two witnesses.

JOSEPH NICHOLS.
