PATENT FRDRIODOSSOGNE, OF ANTWERP, BELGIUM.

DOOR CHECK AND CLOSER.

SPECFICATION forming part of Letters Patent No. 642,591, dated February 6, 1900.

Application filed February 17, 1897. Serial No. 623,902. (No model.) s

To all whom it may concern,.-

Beit known that I, FRDRIO DossoGNE, a citizen of the Kingdom of Belgium, residing at Antwerp, Belgium, have invented certain new and useful Improvements in Door Olosers and Checks for Doors Opening Both Vays, of i which the following is a specification.

My invention relates to an apparatus intended to close automatically doors opening in both directions.

The apparatus is shown, by Way of example, in the accompanying drawings.

Figure l represents the apparatus fixed to the door in a state of rest. Fig. 2 is a longitudinal section of the apparatus at rest. Fig. 3 represents the apparatus as it appears when the door is opened toward the side where the apparatus is iixed, and Fig. 4 when the door is opened on the opposite side. Figs. 5, 6, and 7 show the apparatus furnished with oil-brakes in longitudinal section and the three chiefV Fig. Sis a transverse section on the line a: of Fig. 5. Fig. 9 is a transverse section on the line y y of Fig. 6. Fig. 10 is a view of the chief piston. Fig. 11 shows the construction of the packing-boxes of the brake-cylinders. Fig. 12 shows a cross-section on line z a of Fig. 6 looking toward the pistons, which appear in plan View.

The apparatus consists of a metal cylinder A, closed at both ends by a screw-threaded cap a d. The cap o. has on the outer side a hinge b, by means of which the cylinder A is attached to the door. The opposite cap a has a central opening passing through it, admitting the lever B, the free end of which is jointed to a hinge c, iixed on the upright or post of the door-frame. This lever B is of conical form at its other end and forms with the rod C an articulated joint. The rod C has a shorter diameter than the lever B and is intended to pass through a movable ring D, covering the joint when the apparatus is in a state of rest. The opening of this ring is conical on th`e side of the lever B in order that the conical end of the latter may insert itself in the ring and push it back when the door is opened toward the side Where the apparatus is fixed. On the side turned toward the small rod C the opening of the ring is cylindrical, so as to stop the lever B, but allow the rod C to pass through. This rod C has a positions.

sliding movement in a little cylinder E, which rests against the cap a.. This cylinder carries in the part next the said stopper an outer collar c, on which rests one end of a spiral spring F, the other end resting against the ring D. This small cylinder carries within it at the opposite end a little collar e', adapted to stop the end of the rod C by means of a small piston e2, with which the latter is provided.

The Working of the apparatus Will be readily understood. Vhen the apparatus is at rest-that is to say, when the door is in its normal or closed position-the articulated joint is sunk in the ring D, while the small rod C rests with its piston e2 against the collar e of the small cylinder E. If now the door is pushed toward the side to which the apparatus is fixed, the lever B will rest against the ring D, the spring willbe compressed, and the small rod C will slip into the cylin der E. lAs soon as the door is left to itself, the spring, being relaxed, brings it back to its normal position. If, however, the door is pushed toward the opposite side to that on which the apparatus is fixed, the lever B will pass out through the opening of the cap a',

the joint will fold, and the rod O will draw the small cylinder E by means of the piston e2 and the collar e'. The outside collar e of the small cylinder' will compress the spring, which will relax as soon as the door is set free, as in the preceding movement.

To prevent the door from oscillating or opening and shutting itself several times over, the apparatus may be furnished with oil-brakes. This apparatus is shown in Figs. 5 to 11. Inside the small cylinder E there are two auxiliary cylinders E E2, in which the pistons e4 e5 have a sliding movement. Their rods c and c2 are fixed in the ring D in such a manner that when the apparatus is in a state of rest the three pistons e2 e4 e5 are at the commencement of their stroke-#that is to say, resting against the collar e. The piston e2 is cut away, so as to slide between the outer wall of the cylinders E E2 and the interior wall of the cylinder E. (See Fig. 10.) The cylinders E E2 are closed in their lower part, but the cylinder E is open. The cylin- IOO ders E E2 are filled with oil or other lubricating liquid, and the small pistons e4 e5 are slightly deflected on their rods, so that when these pistons advance the liquid can pass between the :raised portion of the pistons and the adjacent wall of the auxiliary cylinders. lVhen the pistons recede, the oil passes under them through little openings e6 e7, provided in their lower parts. It is obvious that one of these cylinders E E2 may be dispensed with, although the braking or checking action will be more even and satisfactory where both are used, as shown. To prevent the liquid from escaping out of the auxiliary cylinders, the latter are stopped by means of packing-boxes, Fig. 1l. These boxes are composed of ahollow nut f, screwed to the collar c above the auxiliary cylinders. In the cavity of this nut is lodged an india rubber ring f', which lits tightly around the piston-rod. On this nut a second one, f2, is screwed, which holds the ring in its place', allowing a certain play in the horizontal direction. When the door is pushed toward the side on which the apparatus is fixed, the ring D will cause the three pistons c2 c4 c to advance simultaneously into the cylinders E E' E2. The. oil or liquid will pass above the small pistons e4 e5 and will prevent any unsteadincss of motion of the door when it is moved on its hinges for opening in either direction, owing to the pressure of the liquid which flows back only slowly through the little openings underneath the pistons e4 When the door is pushed toward the side opposite that on which the apparatus is fixed, the cylinder E, along with the auxiliary cylinders E E2, being drawn by the rod C, while the rods c c2 remain fixed, the pistons c4 e5 will plunge into the liquid and the same brake action will be elfected as in the previous case, when the door is allowed to swing back.

Having fully described my invention, what I claim, and desire to secure by Letters Patl. In an automatic door-check and doorcloser, for doors opening both inwardly and outwardly, the combination of a longitudinally-fixed cylinder with a spring compressible from either end, a supplemental cylinder movable endwise within the fixed cylinder, a piston sliding in the movable cylinder and arranged to engage the same for moving the latter endwise, a connection between the said movable cylinder and the said spring, an aetuating-lever and pivotal connections from the latter to the said piston and directly to the other end of the said spring, in order that the latter may be compressed Whether the door be opened outwardly or inwardly, the said lever and main cylinder being pivotally attached respectively to the door jamb or other lixed part and to the door, substantially as set forth.

2. In adoor-closer and door-check, the combination of a lever and a spring compressible from either end, a main cylinder inclosing the said spring, a rim within the cylinder directly connected to said lever and an end of the said spring, an endwise, movable, auxiliary cylinder arranged within the said main cylinder and provided with a collar which bears against the other end of the said spring and also with an additional interior collar, a piston sliding within the said auxiliary cylinder and engaging the said interior collar, and a rod having pivotal connection between the said piston and the said lever in order that the spring may be com pressed by the opening of the door in either direction, the main cylinder and lever being pivotally attached respectively to the door and door-jamb, substantially as set forth. i
