Abstract: The disclosure relates to an improvement in closed face type spinning reels, in particular the design and construction of such reels to provide for a high degree of miniaturization and lightness in weight, without sacrifice of operational features. A reel is disclosed which includes a generally cylindrical reel housing containing the working mechanism. A central frame, of generally cylindrical form, mounts substantially all of the working parts, and cylindrically shaped front and back reel casings are removably mounted on the central frame to completely enclose the mechanism. The rear casing mounts a thumb lever for actuating the reel mechanism during casting. An offset, hypoid type gearing arrangement is provided for the winding handle, enabling the main drive gear to be offset within the reel housing, in order to accommodate the presence, in a convenient position, of an adjustable drag control element of conventional but advantageous form.

Abstract: This is a compatible angled gear system wherein the shafts of the pair of meshing gears are at an angle to each other, ranging between a maximum angle of ninety degrees to a minimum angle of forty-five degrees, and wherein the limits of the angles of the gear teeth range correspondingly between forty-five degrees to a minimum of twenty-two and one-half degrees, the angle of the shafts to each other always being just twice the angle of the meshing gear teeth. The gear teeth of the meshing gears are always in a straight line at their point of contact. There is always an odd number of gear teeth in such gears, and the minimum number of teeth for each gear is always five; rights fit rights and lefts fit lefts, with the shafts at an angle to each other.

Abstract: A chainless drive mechanism for a bicycle using a rotatable drive shaft for transferring the pedal actuated driving force from the pedal crankshaft to the rear wheel including shift mechanisms to provide different drive ratios. A pair of discs, each formed with a plurality of concentric series of openings, are mounted on the pedal crankshaft and rear wheel, respectively. A pair of spaced sprocket gears is rotatably mounted on each end of the drive shaft and engaged with a respective series of disc openings. A pair of axially movable ratchet slip gears is fixed against rotation on each end of the drive shaft adjacent a similar ratchet surface formed on each of the sprocket gears. A pair of operator controlled individual shift brackets is movably mounted on the drive shaft, each being operatively engageable with a respective pair of ratchet slip gears.

Abstract: A gear mechanism for transmission of small forces, such as in a hand mechanism gear for clocks or watches which has a driving shaft, a driven shaft coaxial thereto, two gearwheels developed as crown wheels, mounted coaxially engaging each other over a small portion of their circumferences and having each a different number of teeth, one of these gearwheels being stationary and the other rotary. A coupling means such as a clutch is fastened to the driving shaft for rotation therewith. The clutch and the two gearwheels are mounted in relation to each other in such a manner that when the clutch rotates with the driving shaft, the rotary gearwheel resting on the driven shaft, while itself rotating, rolls off on the stationary gearwheel.

Abstract: A powdered metal gear is disclosed for use in an accommodating screw jack. The gear has a planar face, and teeth of generally truncated tetrahedronal shape are disposed around the circumference. A conical gear undersurface acts, with intertooth recesses, to form a first gear portion of substantially uniform material thickness. Scallop indentations in the undersurface mate with the gear teeth themselves to form a second gear portion of substantially uniform material thickness.
