Abstract: 937,926. Hydraulically operated door closers. YALE & TOWNE MANUFACTURING CO. Aug. 20, 1962 [Aug. 30, 1961], No. 31836/62. Class 65 (1). An hydraulically operated door closer comprises a casing 10 containing a cylindrical checking chamber 18 and a cylindrical spring chamber 17 at right-angles to it, an axially mounted crank-shaft 14 in chamber 17 whose square end 30 engages a star-shaped opening 52 in the closer arm 13 attached through adjustable link 15 to a bracket 16 on door frame F, a pin 27 of crank portion 26 of shaft 14 coacting with the bearing 40 of upwardly off-set connecting- rod 38 attached through wrist pin 46 to checking piston 47 so that rotation of shaft 14 against spiral spring 34 joining it to casing 10 is translated into axial motion of the piston 47. As the door closes the piston forces fluid through ports 48 past control valve 49; valve 50 allows free flow through the piston as the door opens. Cover-plate 19 may be removed to give access to cotter pin 27 detachably securing the forked end of rod 38 to crank pin 27. 0-rings 32 in grooves 33 on the crank-shaft prevent fluid seepage.
