DOOR CHECK AND CLOSER.
SPECIFICATION forming part of Letters Patent No. 617,479, dated January 10,1899.
Application filed November 19,1897. Serial No. 659,107. (No model.)
T0 60% whom it may cpncern:
Beit known that I, ADOLF DAMITZ, residing at '75 Planufer, Berlin, Germany, have invented certain new and useful Improvements in a Combined Door Closer and Check, of which the following is a specification.
My invention relates to a combined door closer and check, and has for its object to produce a rotary device for closing doors and checking the closure thereof.
My invention will be understood by referring to the accompanying drawings, in which I Figure 1 is a vertical section of a structure embodying my invention, the section being taken on line 1 1 of Fig. 2; and Fig. 2 is a section thereof on line 2 2' of Fig. 1.
In the drawings, a is a casing in which a rotary spindle b is journaledat one end. The casing a is provided with a cap 0, in which the opposite end of the spindle b is journaled, which cap fits snugly over the casing a to close the same. The lower part of the interior of the casing is shown as inclosing a liquid-chamber d, which is closed at the top by a plate e. This liquid-chamber d contains a suitable fluid. Located within the liquidchamber dis a partition-wall d,having therein an aperture (1 through which fluid may pass. The amount of fluid passing through the aperture (1 may be regulated by the regulatingscrew (i in a manner well understood. A
piston g is fixed firmly to the spindle 1) within the liquid-chamber and is swung by the rotation of the spindle, it being understood that the casing is held stationary, while the spindle turns, the turning of the spindle being effected by the arm h, which is attached to the door or the door-jamb, as the case may be. This piston g is, not quite longenough to reach the inner face of the wall of the easing and is provided on its working face with a suitable flexible packing g or flap-valve whose edge contacts with the inner face of the wall of the casing. The partition-wall (1' also does not quite reach the spindle and is also provided on its working face with a flexible packing d or flap-valve which reaches beyond the edge of the division-wall and contacts with the spindle, it being understood arrow in Fig. 2, and the liquid will pass freely 4 over the edges of the partition d and piston in the liquid-chamber, the packings or flapvalves readily yielding to the flow of the liduid. While the door is being closed by the spring, the movements of the parts will be in the direction of the arrow, whereupon the packings or flap valves g and (1 will be brought firmly against the sleeve g and partition-wall a, respectively, and the only conduit for the water will be through the aperture 01 so that the said liquid-chamber will regulate the closing of the door by the spring. It will be observed that the amount of liquid passing through the aperture d in a given time may be very efliciently regulated by the regulating-screw d which extends into the said aperture (1 and may be adjusted therein from the outside of the casing c.
Having described my invention,what I claim, and desire to secure by Letters Patent, is-
In a combined door closer and check, the combination of a casing suitably divided into spring and liquid chambers, aspring-restored spindle adapted to be rotated by a door, a piston carried by the spindle in the liquid-chamber, the said piston being slightly too short to reach contact with the side of the casing, and provided with a loose flap or valve 9 adapted to reach contact with the casing, the said loose flap abutting strongly against the piston and reaching contact with the side of the casing when the piston is moved in one direction and swinging freely away from the piston and casing when the piston is moved in the opposite direction, and an apertured partition dividing the liquid-chamber and provided with a flap (1 adapted to reach contact with the rotating part of the piston or spindle and abutting against the partition and rotating part of the piston or spindle when the liquid is moved in one direction and swinging freely away from the partition and piston or spindle when the liquid is moved in the oppotherethrough and adjustable from the outside site direetiomwhereby the rotation of the pisof the casing, substantially as described. ton in one direction Will be checked by the 1 1r liquid and the rotation of the piston in the ADOLB DAMI l opposite direction will be comparatively free, \Vitnesses:
