Abstract: A sheet steel poly-V-grooved pulley having a special cross-sectional contour is made optionally by any one of three different cold working manufacturing procedures. Special physical properties or characteristics are developed in the pulley by the manner in which the metal in the V-groove body and single and double walled terminal flanges are cold worked. The cold working involves forming in stages of manufacturing from a cup-shaped blank to the finished pulley product a stepped inner body wall surface equivalent to a tapered surface with improved substantially uniform torque transmitting strength in the grooved body from web wall to open end. Also involved in the cold working is an increase in pulley diameter in certain portions of the finished pulley and a decrease in diameter in other portions from the diameter of the side wall of the cup shaped starting blank.

Abstract: A spare tire is provided for passenger autos to replace the usual fifth pneumatic tire and wheel assembly supplied as original equipment with autos. The tire includes a metal hub having an annular bulge to provide clearance for the brake calipers of an auto equipped with the tire. A series of rim segment assemblies with tread rubber thereon is mounted on the periphery of the hub member forming the tire rim. Each segment has a T-shaped metal member the T-stem of which is generally trapezoidal in shape and is vulcanized-bonded to a rubber block similar in shape which has an opposite surface vulcanized-bonded to a thin sheet metal segment. Each rim segment assembly is separately connected by suitable means to the hub member. A protective device guarding against tire collapse in event of failure of a bond between the rubber block and a metal member, engages the T-stem and hub member.

Abstract: A note picker mechanism for picking new and circulated paper money bills from stacks thereof through access openings of sealed, tamper-indicating containers for the notes when installed in ATM's. The mechanism has a primary suction picker device and a secondary friction-engaging picker device. The friction-engaging picker is switchably engaged with or disengaged from the suction picker so that if a picking failure occurs, the picker mechanism is automatically changed from joint operation of the primary and secondary picker to operation of the primary picker alone, or vice versa, to correct the cause of the picking failure.
