APPARATUS FOR OPENING DOORS.
SPECIFICATION forming part of Letters Patent No. 550,338, dated November 26, 1895.
Application filed August 21, 1894. Serial No. 520,911. (No model.) Patented in Germany May 14,1893, No. 75,178.
To all whom it may concern:
Be it known that I, GEORG BAUER, a subj ect of the German Emperor, residing at Nuremberg, Bavaria, Germany, have invented certain new and useful Improvements in Hinge Devices for Doors, Windows, Box-Lids, and the Like, (for which I have received a patent in Germany, No. 75,178, dated May 14, 1893,) of which the following is a specification.
This invention relates to a device which renders it possible to open doors, windows, lids of desks, and the like movable closing parts to both sidesthat is to say, either to the right or left or inward or outward. This object is attained by revolubly attaching the door, lid or the like to one end of each of two levers, which cross one another or run parallel, the other ends of the levers being hinged to the frame or casing which is to be closed.
Various forms of construction of this improved device are shown in the accompanying drawings, the first of which, Figures 1 to 7, has the following peculiarities: Bars (0 on the casing and c on the door or other closing part) are attached to the casing a, as well as to the corresponding edges of the door or the like b at the top and atthe bottom. Between these bars levers d are arranged, which connect one end of the bar fixed to the casing to the other end of the correspondingbar on the door or the like and are revoluble at both points of connection by means of pins 6 or the like. The bars 0 and 0 may also be replaced by suitable bolts or swivels or the like.
By this arrangement two axes of rotation are produced, one to the left and one to the right, on which the door or the like may swing. The rotation takes place either by means of the lever 61 turning 011 the pivot attached to the casing, Fig. 5, or by the door or the like swinging on the pivot attached to the lever vrest,so as to half encircle them, Fig. 7.
tom on the left-hand side. WVhen the door is closed, the pivots fixed to the door or the like are correspondingly brought at the top to the left and at the bottom to the right. An axis of rotation is thus formed at each side by one pivot fixed to the casing and one fixed to the door, the center lines of which must coincide. Hooks 9 may be arranged in these center lines at both sides of the casing, on which hooks suitably formed bands f may If the door be opened to one side, the bands f on this side engage the corresponding hooks g, Fig. 1, and prevent the turning of the door in the opposite direction. A further security may consist in providing projections i on the levers (1, Figs. 5 and 6, which projections engage with spring action in suitable recesses 10 of the bars 0 and 0 similar to a hinged rule. If then the door he opened in one direction, the projections t', which retain the door in this direction-that is, those on the larger lever-arm-will be drawn out of their corresponding recesses, while the other proj ections remain in their recesses. When the door is closed, it may be fastened either by means of a double lock situated in the center of the door or by two locks arranged at the sides.
It is readily evident that the above-described arrangement may be applied to such doors or the like intended to be opened both inward and outward.
This improved device is suitable both for the closing parts of door and window openings and also for boxes and receptacles of all kinds.
The arrangements shown in Figs. 8 to 13 are acompletion of the above-described object, by means of which a sure guidance is provided in opening the doors or the like. For this object pins or pivots Z are attached both to the right as well as the left hand posts, which pins form with their sockets m, fixed to the door, to all appearance ordinary straphinges. The part Z, attached tothe door-post by means of the projection n, has a pin 0 at the top, on which at both sides planes par allel to the axis are formed, Figs. 10 to 13. The part m, attached to the door,is provided with a ring or socket in the usual manner into which the pin 0 engages. At one point ICO this socket has a slot 19, which is somewhat broader than the pin 0 across the parallel planes.
In Figs. 10 and 12 the door-hinge is shown with the door closed. In this position the part on may be drawn away from the part Zby means of the slot 1). This takes place when the door is turned on the pivot placed 011 the opposite side. W'hen the door is turned on the pivot, this aifords at once a guide, so that the door can never be lifted from off its doorposts.
Figs. 11 and 13 show the opposite positions of the partsl and m when the door is opened. The arrangement may also be reversed namely, the segment-pin may be attached to the door and the slotted socket to the doorpost.
The arrangement may of course, as already stated at the commencement of this specification, be also made in such away that both levers may be fastened on the same side of the lid or the box, so that in one case the rotation takes place on the pivot attached to the box and in the other case on the pivot atsockets f or m supported on the oppo-' site edges of the door, and the hooks or pins y or 0 supported at the ed es of the casing, substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
