Abstract
886,924. Door operating appliances. RIXSON CO., OSCAR C. June 5, 1959 [Dec. 19, 1958], No. 19284/59. Class 65(1). A door checking and closing mechanism comprises a frame structure 1 (Fig. 2) for attachment to the top of a door 4, a check cylinder 3 fixed within the frame structure and provided with a piston assembly 6 connected to a spindle 57 having a gear connection with a rack 56 so that it moves longitudinally relative to the frame and cylinder when rotated, and an operating arm 87 fixed to the spindle for slidable engagement with the lintel, the movement of the piston assembly when the door is opened being resisted by a doorclosing spring 17 The embodiment illustrated comprises two identical piston, cylinder and spring assemblies. Each piston 13 has a connecting rod 15 which extends through an annular seal 43 at the end of the cylinder 3 and an aperture in a plate 49 and is pivotally connected by a pin 68.1 to a clevis 67 pivotally attached by a pin 68 to a yoke bar 65 (Fig. 14) carried by pair of travelling carriages 60 in which the spindle 57 is mounted. The plate 49 forms one of two similar ends of a fixed frame for the travelling spindle assembly, the frame also comprising two U-shaped side rails 47 (Fig. 13) and longitudinal support members 51 all of which are formed with identical openings 53 to accommodate movement of the spindle. The rack 56 comprises a plurality of similar laminations, the rails 47, support members 51 and rack laminations being secured together by rivets 58, 58.1, and all having end lugs which extend through and are anchored to, the end plates 49. Each travelling carriage 60 comprises a plurality of. identical laminations and is guided within one of the U-shaped side rails 47, a needle or like anti-friction bearing 61 being located/between each carriage and the base of the U. The operating arm 87 is keyed to the upper end of the spindle 57 and carries a guide roller 89 at its other end which slides longitudinally in a guide rail 91 on the lintel when the door is opened or closed. The frame structure 1 of the closer comprises two similar longitudinal sections 1.1, 1.2 (Fig. 13), made narrow by incorporating the fixed frame for the travelling spindle assembly into the side walls of the sections, and is mortised or surface mounted at the head of the door. To obtain correct operation of the closer it must be mounted with the teeth of the rack pointing away from the direction of the door opening movement, and to facilitate this it can be attached either in the position shown or in an inverted position, the operating arm 87 being then keyed to the opposite end of thai spindle. Door checks. The check cylinders 3 are identical and are hydraulically linked -by passages 77 (Fig. 2) to, co-ordinate their action. During the door opening stroke fluid flows from, left to right of each piston 13 through a valve 25 (Fig. 17), additional fluid being drawn from a reservoir 7 to compensate for the displacement of the piston rod 15. Each reservoir is provided with a closed resilient cap 70 (Fig. 11a) which collapses as the fluid is drawn out, the cap being bonded to the reservoir and provided with a stiffening member 73. It is stated that the cap may alternatively be made of metal. During the check stroke fluid from in front of the piston flows initially through a passage 79 and valve 83 into the reservoir 7 and thence into the cylinder behind the piston through a passage 75. As the door approaches the latching position a bevelled portion 29 of the piston gradually covers the passage 79 and diminishes the rate of fluid flow, and immediately before this passage is completely covered the rear portion of the piston exposes the outlet port 82 of a passage 81 controlled by a valve 85 and communicating with the space in front of the piston to allow a rapid final closing movement. Each cylinder is provided with a pair of valves 83, 85, the pair which are uppermost and accessible when the closer is attached to the door being used for adjustment, the other pair having been fully closed before attachment. Stays. The roller 89 on the operating arm 87 is spool-shaped and co-operates with a resilient guide bar 95 (Fig. 7) extending along one side wall of an elongated rectangular housing 91 mortised in, or surface mounted on, the lintel. The roller is maintained in engagement with the guide bar by a guide rod 97, which is mounted in apertures in the ends of the housing 91 and carries a stop 113 (Fig. 8), preferably made of metal, which has a concave portion 117 to seat the roller. The stop also has a projecting lug 119 which cooperates with one of a series of holes 99 in the side wall of the housing 91 opposite the guide bar 95 and locates the stop in the housing. When the door reaches a predetermined open position the roller engages the stop, and is held in engagement therewith by the resilience of the material of the bar 95 to hold the door open.
