    Abstract: An overhead door apparatus utilizing a torsion spring counterbalancing mechanism. The counterbalancing mechanism includes a worm drive ring-shaped gear winding mechanism for setting the appropriate torque or number of winds in the spring. A counting mechanism is provided to indicate to the installer the number of winds being given to the spring. Means are also provided for accommodating spring growth and contraction during winding and unwinding using the winding mechanism and during normal raising and lowering of the door. A spring clip gear retainer is disclosed for preventing rotation or creep of the worm drive gear and spur gear during normal raising and lowering of the door. A second embodiment is disclosed allowing more universal interchangeability of components between the left and right sides of the door system, easy snap-in assembly, and including a telescoping spring cover. Each embodiment includes a spring winding counter.

    Abstract: An improved load compensator for a spring counter-weighting mechanism including a snail cam to provide a constant counter-weight force is described. The cam provides a constant torque to a drum on which are wound cables for exerting a constant counter-weighting force. A manually operable device for altering the relative radial positions of the cam and drum varies the amount of the constant counter-weighting force. The cam is rotated with respect to the drum by a spur gear fitting within a ring gear fixed to the drum and rotated by a knob connected to an axle carrying a pinion gear engaging the spur gear. The spiral surface can be effectively reconfigured with respect to a portion of the cable fitting therearound.

    Abstract: An improved window sash balance and components thereof. The balance includes a spring fixed with respect to the frame and a pair of pulley blocks, each containing one or more pulleys. One block is fixed with respect to the frame and the other is disposed on the end of the spring. A cord is secured to one pulley block and trained over the pulleys. The other end of the cord terminates in a hook adapted to be received in an opening in the window jamb channel. The pulley block unit includes a pulley-receiving frame, one, two or three pulleys received therein, and at least one axle for rotatably supporting the pulleys within the frame. The block has one or two pulley-receiving openings therein, and suitable openings for reception and positioning of the axle. The block includes first and second pairs of assembly reference surfaces forming a part of the block and spaced radially from the axle opening. The axle-receiving opening in the pulley and in the block each include outwardly tapering guide or pilot surfaces and the axle includes one or two inwardly tapering pilot surfaces. The size of the pulley and the positioning of the reference surfaces are arranged so that when an outer edge of the pulley is in coplanar alignment with the reference surface, the tapering margins on the axle and the pulley will engage and serve to align the pulley as the axles are positioned in the block.
