Abstract

425,241. Door-operating appliances. ADAMS, J. S., 3, Emerald Street, Bloomsbury, London. Sept. 28, 1933, No. 26737. [Class 65 (i)] A door closing and checking device comprises a spindle, carrying the door, rotatable in a cylinder in which slides a piston - carrying member having a pair of cam surfaces engaging a pair of anti-friction members carried by the spindle so that rotation of the spindle causes sliding of the spindle, a spring being provided to oppose motion in one direction and the usual valve-controlled passage being also provided. In the form shown, the cylinder 3 is fixed to the hinge post of the door and the spindle 6 is squared at the top for non-rotary attachment to a member fixed to the door. The lower part of the spindle carries a transverse pin on which is mounted a pair of rollers 4, Fig. 6, engaging between a pair of face cam surfaces 1<a>, 5<a> on a hollow member 1, the upper cam surface 1<a> being formed on an integral part of the member 1 while the lower is formed on a member 5 fixed in the lower end of the member 1. A piston 2 is fixed to the top of the member 1, and has packing 12 to prevent leakage of oil along the spindle 6. Rotation of the member 1 is prevented by keys 15 thereon engaging slots in a bearing cup 14 fixed in the bottom of the cylinder 3, so that rotation of the spindle 6 causes sliding of the piston along the cylinder, upward movement of the piston being opposed by a compression spring 7, bearing on the top of the piston, which returns the piston and closes the door. The cylinder 3 is filled with oil, and a byepass passage (not shown) in the cylinder wall connects the space above the piston to one of the slots in the cup 14, whereby oil can flow from one side of the piston to the other. A ball valve in this passage allows free flow of oil when the piston is moving upwards, but restricts the flow in the reverse direction, the resistance to flow being regulated by a screw preventing complete closing of the valve ; this screw is arranged horizontally, and has an inclined end engaging an inclined upper end of a vertical pin against the lower end of which the valve ball seats.
