To all whom it may concern:

Be it known that I, ALoIs ABZUG, a subject of the Emperor of Germany, residing at 12 Oelsnerstrasse, Breslau, German have invented certain new and usefu Improvements inCombinedI-Iinges and Fastenings for Doors; 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 whichit appertains to make and use the same.

This invention relates to doors which are hinged on both sides and are turned upon either set -of hinges by withdrawing the hinge-pins of the other set, the hinge-pinsbeing so connected by means of across-bar that only one set of pins, and therefore only one side of the door, can be freed at a time. Latch-bolts are also provided for further securing the door and arranged to be operated in connection with the hinge-pins.

The distinguishing feature of the invention is that the cross-bar is moved by levers which are so connected with the latch-bolts that after the hinge-pins have been withdrawn on the side on which the door is to be opened either pawl can move its latch without the cross-bar being further actuated.

The invention is illustrated in the accompanying drawing.

Figure 1 shows the fposition of the. arts in a door opening as ale t-hand door. ig. 2 is a detail front view of one of the bolts on a larger scale. Fig. 3 is a similar view of the same in a different position. Fig. 4 is a like view of the same in a still further osition. Fig. 5 is a side elevation of a specia form of the lever connection by means of which when the lever is lowered the hinge-pin is withdrawn from the door-hinge and the latch-pin ulled back atthe same time, while when the ever is released it is returned, with the latchbolt, to its initial position; and Fig. 6 is a front elevation of a further modification,

nect the parts 0 and d of the hinge, are formed on the ends of side rods f, provided with slots and sliding vertically on guide-pins g, working inthe slots. Rollers h are mounted to rotate on the adjoining ends of the rods f and against shoulders n on the cross-bar.

take into slots 'i in the cross-bar k, which connects the right and left hand side rods f together.

The cross-bar 7c is moved by the leverarms 1, carrying projections m, which bear Each shoulder at terminates in a curve 0, along which when the cross-bar 7c has been moved into one of its extreme positions the rojections m can slide without actuating t e bar. A lever fast with the lever 1, acts on the latch-boit 1' through the stud t. This latch is kept constantly pressed into the door-post by a spring 8 and can be pulled back by the lever p. The lever 1) slides, with its pin t, in an opening a of the latch of such dimensions that when the lever begins to turn the pin t at first runs idly in the part u and onl strikes against the bow piece 12 and pulls bac the latch 1' after the PI'OJGOtiOIl m onthe lever Z has'begun to run over the curved part -0 of the cross-bar.

In order to keep the cross-bar firm in the central position, it is provided with a recess between the projections 2. In this recess the bolt of a lock y can be caused to engage. For the purpose of indicating the central position a spring 2 is arranged, which slides on the bar It and when the bar is is in the middle position catches in a notch 3.

The action is as follows; If the door is to be opened on the left and the parts of the device are still in the position shown in Fig. 2, it is necessary that the operating-handle 4 should be moved into the position as in Fig. 1. In connection herewith the rojection, m of the lever Z presses the cross-E left until it comes into the position shown; in

Fi s. 1 and 3. In consequence of thisthe roilers h are caused to a proach each other and the hinge pins e on t e side rods f drawn out of the hinge parts 0 on the left door-post. On the right side when the cross-bar 7c was moved the rollers h of the side bars were forced apart and in this manner the nged connection on the right side of thedoor effected through the pins 0 on the side rods. The door is now only closed on the left side by the latch r, whichvis not affected by the initial movement of its 0 crating-lever p and pin tthat is, while the ever is moving from the position shown in Fig. 2 to the osition shown in Fig. 3. In order that t e door may now be fully released, it isnecessary that thelever Z should be moved still farther to the position shown in Fig. 4. As the latchar 79 to the the left it is not necessary that the side rods f and hinge connections should he moved, the closing being eil'ected only by the lefthand latch 1'. If, on the other hand, the door is to be opened on the right, the handle 5 is pressed out of the position shown in Fig. 1

into the position shown in Fig. 3. he hinge connection on the left side of the door is thereby reestablished and the connection on the right side of the door released by drawing the pin e out of the hinge-pieces c.

When the handle 5 is tunred farther down, right-hand latch r is drawn back. In this form of the invention during the early period of the lowering of the lever the hinge-pin is moved without the latch-bolt being influenced by the lever, and in the second period of the lowering the latch-bolt only is influenced, while there is no longer any movement of the crossbar. The consequence of this arrangement is that except when the door is quite closed the levers assume different positions in relation to one another, as on the side of the door on which the hinge-pin is drawn out of the door-hinge the lever is already turned to a certain angle in relation to its lnitial position, while the lever on the other side of the door, where the hinge-pins are pushed into the door-hinges, still takes its highest position.

In the form of the invention shown in Figs. 1 to 4 the side rods f are divided in the middle. In this arrangement they consist of asingle piece and are so constructed that the lower as well as the upper end e of each rod f when moved goes up out of its lug c. The ri ht-hand-side rod is connected with the left-hand-side rod by means of a lever h, which is pivoted at g in the middle of the door in such a manner that when the one rod is raised the other is lowered- As in the construction of the door it is desirable that both door-latches should be drawn out of the door-posts simultaneously when the door is opened, a connection is established between the latches, so that when one of the levers is lowered the movement is transmitted to-the door-latch on the other. This is suitably effected by extending the guide-bars of the latch as far as the middle of the door and connecting their ends by means of a double-armed lever, so that when the one latch is moved toward the middle of the door the other door-latch is likewise pulled toward the middle of the door by means of The function of the double performed in the present case by eel in which teeth arranged on the double lever. lever is best a toothed w the door-latch guides engage from above and below. The guides 6 for the door-latches r are extended in the direction of the middle of the door and there furnished with toothing 7, in which a tooth-wheel 8, acting as a double lever, engages, and it willbe seen that when the toothnvhecl is rotated the guides 6 6 are thereby moved in opposite directions. If the door be opened to the left, by lowering the right-hand door-lever, Fig. 6, the right-hand latch 1' is pushed back by the lever p of the right-hand door-lever and the guide of this latch moves in the direction of the arrow 9. The guide rotates the toothed wheel in the direction of the arrow 10, and hereby the left-hand door-latch r is pushed" in the direction of the arrow 11, so that when the door is opened both door-latches are drawn out of mounted for longitudinal movement, a crossbar mounted for movement across the door,
