HINGE.

SPECIFICATION forming part of Letters Patent N o. 712,219, dated October 28, 1.902.

Application filed March 5, 1901.

To all? Lvl/1,0112. t may concern/f Be it known that I, FREDRIOK F. TRYoN, of Syracuse, in the county of Onondaga, in the State ot'v New York, have invented new and useful Improvements in Hinges, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to a concealed hinge, whose essential features are'a link pivotally connected both to the jarnb and to the door at adjacent sides of corresponding mortises in each, and a locking-piece adapted to engage first with the ydoor portion of the hinge, so that the door as it is opened will first swing on the jambjournal without changing its relation to the link and without swinging on the door-journal until it has reached the halfopen position at right angles to the jamb or wall. At this position the locking-piece is arranged to disengage from the door portion and the door is then swung back into wideopen position on the door-journal. When the door is closed, the operation is reversed. This mode of operation and result may be 4veffected by various mechanisms, and I do not "propose to limit myself to the form here shown; but I have illustrated a simple and economical form of hinge for producing this result, in which corresponding segments or quadrants are arranged in both mortises and secured, if desired, on the respective hingeplates in the base of each niortise. The doorsogment has a notch in its upper end and the jamb-segment in its lower end. A'lockingpiece is pivotally carried at its middle in the slot in the. hinge-piece, so that its bent or hooked ends engage with said notches. The function ofthe door-segment notchis to receive the outer end of the locking-piece,'per mitting the disengagement of the other end of the locking-piece from the jamb-segment notch, so that the door will swing on the jambjournal. The function of the jamb-segnient notch is to receive at the proper time the opposite hooked end of the locking-piece, per- V mitting the door automatically to unlock fro m the link and to swing on the door-journal, while at the same time the link is locked to the jamb, so the door cannot swing on the jamb-journal, thus insuring a proper movejarnb-plate 5 by jamb-journal 12 ment in the opening and closing of the door Serial No.` 49,767. (No model.)

and permitting it to swing on onlyone journal at a timeon the jamb-journal-when it is being swung from closed to half-open position,l and Vice versa, and on the door-journal when it is being swung from half to full open position, and Vice versa.

My invention is shown in the accompanying drawings, in which the same reference-numerals used in tho specification indicate the same parts in all of the figures.

Figures I, II, and III are cross-sections on line I I of Fig. IV of jarnb, door, and hinge in first, second, and third positions, showing, respectively, the door closed, half open, and full or wide open. Fig. IV is a top plan view of my invention with the door wide open. Fig. V is a cross-section of Fig. IV on line V V.

In the figures, l indicates the jamb, and 2 the door, both formed with corresponding mortises 3 and 4.. In the base ofthe mortises are secured, respectively, the jamb hingeplate 5 and the door hinge-plate 6, on which maybe secured, respectively, the jamb-segment 7 and door-segment 8, notched, respectively, at their upper and lower ends, the jamb-segment at 9 and the door-segment at IO. The link 11, bent, preferably, twice at right angles, as here shown, so that the door may be journaled to the jamb at or near the bottom of both mortises, is connected to the and to the door-plate 6 by jamb-journal 13. This link is formed with slot ll'of a width sufficient to admit freely the segments, and at about its central axis is journaled in this slot by pin 15 the locking-lever or locking-piece 16, having hooked ends at 17 and 18 to engage, respectively, with jamb notch 9 and doornotch 10.

As shown in Fig. I, the end 180i the lock` IOO The adjacent edges of the door and jamb are preferably curved at 2O and 2l to insure a closer fit, permitting the door to swing into place when closed, and vice versa.

My hinge is of few parts, is very simple and economical to make, is entirely concealed in the mortise, is durable, and may be as strong as desired and adapted to very light doors, as those of cupboards or boxes, or to the heaviest, and because the journals 12 and 13 are arranged within the edge of the door and jamb the radius on which it swings is greater and the door, as shown in Fig. II in the half-open position, is Wider open by the thickness of the door than in the case where common hinges are used.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In hinge mechanism for a door, the combination with the door and the jamb correspondingly mortised on their adjacent edges, of a U-shaped link hinged by one leg in the base of the door-mortise and by the other leg in the base of the jamb-mortise, the hinge connections being on adjacent sides of the door and jamb mortises, a supplementary locking-piece carried on the link and adapted to engage with the door and lock it to the link, so that the door swings on the jambhinge during the first half of its swing, and then adapted to engage with the jamb and lock the link thereto so that the door swings on the door-hinge during the second half of its swing.

2. In a concealed hinge, the combination of a link journaled to the door and to the doorsupport with a locking-piece pivotally supported on the link, and means to effect engagernent of the locking-piece with the door while the door is swinging from closed to halfopen position, and means for releasing the locking-piece from the door and locking it to the support while the door is being swung from half-open to open position.

3. Ina concealed hinge, the combination of a link journaled to the door and to the jamb and having a cross-slot, of a locking-piece pivotally supported on the link in the slot and having hooked ends, a segment secured to the janib and notched at its lower end, and a second segment secured to the door and notched at its upper end, for engagement with the hooked ends respectively of said locking-piece, substantially as shown and described.

4. A door and door-jamb formed with corresponding mortises and a concealed hinge therefor, having in combination hinge-plates secured in the bottom of each mortise, a substantially U-shaped link hinged by its respective legs to said hinge-plates, said link being formed with a continuous slot at right angles to the door and extending from one hinge-bearing to the other, a locking-piece, having hookcdnends, pivotally supported in said slot at the center of the link, a segment secured on the jamb hinge-plate to extend through said slot and notched at its upper end, and a segment secured on the door hinge-plate to extend through said slot and notched at its lower` end, said locking-piece engaging with the door-segment notch during the rst half of the swing and with the jamb-segment notch during the second half of the swing.

In testimony whereof I have hereunto signed my name.
