DOOR OR SHUTTER.

SPECIFICATION forming part of Letters Patent No. 759,163, dated May 3, 1904.

Application filed July 6, 1908. Serial No- 164,445. (No model.)

To all whom it may concern:

Be it known that I, JosErH DIERICKX, a subject of the King of Belgium, residing at Uccle, near Brussels, Belgium, have invented certain new and useful Improvements in Doors or Shutters, of which the following is a specification. 1

This invention relates to improvements in the known kind. of doors or shutters the panels of which are divided diagonally.

The object of these improvements is more particularly to .allow of the use of the said doors in places where only a small amount of space is available and where it would be impossible to move the two panels in opposite directions on their pivots.

The invention essentially consists in suspending one panel from the other so that they can pivot and slide on one another and be rigidly united to one another at a given moment, sothat the opening of the door is effected by a compound movement consisting first in pivoting the lirst panel about its axis of suspension and then in pivoting the two united panels about the pivot of oscillation of the second panel. The control of the rotatable panels can be effected by means of various devices. In some cases it is sufficient to provide the suspended panel with a simple button or handle adapted to be rotated twice through an arc of forty-five degrees for the complete open ing and closing of the door. In other cases the panels can be pulled by means of a cord attached to the suspended panel and provided with a balance-weight or not. The control or operation of the panels can also be efiected by means of a system of levers connected to both. The door can be double, if necessary-that is to say, four panels can be used in two pairs. Since the latter are identical with each other, it will be suificient to describe a door comprising one pair of panels.

In the annexed drawings, Figure 1 is a dia gram illustrating the'principle of my invention. Figs. 2 to 4 show the inside of the improved door with the panels in their three principal positions.

As shown in Fig. 1, the door comprises two panels 1 and 2, cut diagonally. The panel 1 is suspended from the panel 2 at the point 3 and adapted to pivot or slide on the latter, which is pivoted at the point 4. The panel 1 is provided with a flange 5. To open the door, the aperture of which is indicated by the dotted line 8, it is sufficient to seize the panel 1- by means oi the handle 7 for instance-and rotate it through an arc of forty-live degrees about the point of suspension 3, so as to move the panel 1 into the position 1", in which its flange 5 is in contact with the panel 2. The handle 7 being then pushed farther, the panel 2 is moved by the panel 1 and rotates with the latter about the pivot 4, so that when the two panels reach the position 2" 1 by rotating through the eighth of a circle about the pivot4 the door-aperture 8 is completely open. To close the door, the handle 7 is moved in the opposite direction. To facilitate the return movement, the center of gravity of the united panels in their position 2? 1 is preferably on the closing side of the vertical above the pivot 4. The two panels are also assembled by means of a suitable device which does not become unfastened until the panels again reach the position 1 2, in which the panel 2 bears on a stop 6. After this the panel 1 alone swings about the pivot 3, and the door is closed again.

In the form of construction shown in Figs. 2 to 4 the control of the two panels is efi'ected by means of a system of lovers collectively pivoted at 9. This system of levers comprises a bell-crank lever 10 11, pivoted at 9, the longer-arm 10 of which carries the handle 7. To its arm 11, is pivoted a rod 12, connecting it to another bell-crank lever 13 14, pivoted.

to the panel 2 at 15 and connected to the panel 1 by a short rod 16, pivoted to the latter at 17. The panel 2 is adapted to slide in a guide 18, and the arm of the lever .10 slides in a guide 19. The panel 2 carries at its upper part a detent or catch 20, the arm 21 of which bears on the guide 18 in the closed position of the panel 2 and is thus'held horizontal. The catch itself is adapted to engage a tooth 22 on the lever 13 14, so as to connect the two panels during their rotation about the point 4. By lifting the handle 7, Fig. 2, the panel 1 is moved, by means of the levers, from the position shown in Fig. 2 to that shown in Fig.

3 by causing it to move about the point of suspension 3. By continuing to rotate the lever 10 to bring it into a vertical position the flange 5 of the panel 1 moves the panel 2, so that both panels now rotate about 4:. The arm 21 of the catch 20 now clears the guide 18, and the released catch rotates by gravity till it engages over the tooth 22, which is then exactly below the catch, Figs. 3 and 4. The panels thus connected are moved into the position shown in Fig. 4, in which the door is open. For closing the door the lever is moved from the vertical to the horizontal position. The two panels move in the opposite direction and remain united until on the arrival of the panel 2 to its original position the finger 21 of the catch 20 abuts against the guide 18, so that the tooth 22 is disengaged from the catch and the panel 1 rotates alone into its closing position, which is insured by the engagement of the hook-shaped end 23, Fig. l, of the lever 10 into an aperture 24 to introduce itself into a notch made in the threshold.

What I claim is 1 1. A door or shutter comprising in combination a pair of diagonally-divided panels, one of said panels being pivotally suspended from the other which is mounted on a fixed pivot, and the two panels adapted to be rotated together about said fixed pivot substantially as described.

2. A door or shutter comprisingin combination a pair of diagonally-divided panels, one of said panels being pivotally suspended from the other which is mounted on a fixed pivot, a flange on the suspended panel adapted to engage said other panel and means for first rotating the suspended panel about its point of suspension and then the two panels together about said fixed pivot substantially as described.

3. A door or shutter comprising in combination a pair of diagonally-divided panels, one of said panels being pivotally suspended from the other, which is mounted on a fixed pivot, a flange on the suspended panel adapted to engage said other panel, means consisting of a system, of bell-crank levers, and connectingrods pivoted at a fixed point for first rotating said suspended panel about its point of suspension and then the two panels together about said fixed pivot and means for connecting the two panels together during such combined rotation, substantially as described.

4. A door or shutter comprising in combination a pair of diagonally-divided panels, one of said panels being pivotal ly suspended from the other, which is mounted on a fixed pivot, a flange on the suspended panel adapted to en-' gage said other panel, means consisting of a system of bell-crank levers and connectingrods, pivoted at a fixed point for first rotating said suspended panel about its point of suspension and then the two panels together about i said fixed pivot, means for connecting the two panels, together during such combined rotation, consisting of a gravity-catch pivoted to one of the panels and adapted to engage a member fixed to the other panel, and means for holding said catch out of engagement substantially as described.

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

JOSEPH DIERICKX.
