Abstract

2827. Roots, J. D. Feb. 7. Hinges for seliclosing doors are provided with balls which are located in helical grooves on the two flaps and hinge spindle. The hinge-pin B is provided with a shoulder Z resting on a corresponding shoulder N' of the hinge-plate N, and is secured by screwed knobs Y, Y<1> and grub-pin X. It passes loosely through lugs N', N<3> and O<1>, O<2>, formed integrally with the plates N, O, respectively. The spindle and lugs have corresponding helical grooves in which balls E are placed, sufficient in number in each lug for one revolution of the thread. For doors that are required to close when moved in either direction, the spindle B, Fig. 4, is provided with a groove, the thread of which is partly righthand and partly left-band, and two balls are fitted on each side ; a vertical groove may be cut to enable the balls to be placed in position. Plates, washers, &c. are used to keep the balls in their desired positions.
