Abstract: An interlocking drive plate for an anilox roll which incorporates a dowel pin with a bushing that is able to move slightly and rotate. The interlocking drive disc is similar in structure to the current structure of a drive disc for the Mark Andy P-Series printing presses. However, the stationary dowel pin has been replaced with a modified dowel pin which includes a bushing providing slight movement and rotation. The modified dowel pin, with slight movement and rotation, reduces the shear forces on the pin which in turn reduces the wear on the pin when rotated by a servomotor. This reduction in wear will cause the interlocking drive disc to last longer than traditional drive discs without the need for repair or replacement.

In an intermeshed state, neither the male nor the female component can ‘slide’ relative to the other regardless of whether the male and female components are arranged in a parallel or perpendicular orientation. A method of making a bidirectional gear set is disclosed.

The speed reducer comprises a casing to be attached by the 12V direct current motor, an end planetary gear set driven by the motor, and an output shaft rotary attached to the casing and driven by the planetary gear set.

Abstract: It is frequently observed that when a real locomotive starts up, the front set of drive wheels commences to turn before the rear set of drive wheels begins to turn. The present invention is a simple device that permits this effect to be simulated in a model locomotive. The electric motor of the model locomotive drives a worm which turns a first gear. A second gear is mounted on the same shaft as the first gear but is not otherwise connected to the first gear. From the side of the first gear that faces the second gear, a pin extends at a particular radius. Similarly, two pins extend at the particular radius from the side of the second gear that faces the first gear. When the motor starts, the first gear turns immediately, but rotation of the second gear is delayed until the pin on the first gear strikes one of the pins on the second gear. In this way a delayed rotary motion is imparted to the second gear.

Abstract: A gear combination is disclosed in which a spherical body has a plurality of grooves defined therein into which a pin gear enmeshes. Substantially all the pins on the pin gear engage the grooves in the spherical body at all times. The spherical body rotates about a first axis and the pin gear rotates about a second axis. The grooves are cut into the spherical body by a computer-controlled milling machine. The groove is endless or eventually returns to its beginning position. The axis of the milling tool may be oriented at any angle with respect to the axis of the lathe head, since the resulting motion of the milling tool necessarily cuts whatever lissajous shape is dictated by the relative periodic motions of the lathe head and milling table. The pins in the pin gear thus follow the grooves defined in the spherical body so that the rotation of the pin gear relative to the spherical body mimics the relative motions of the lathe head and milling table when the spherical body was cut.

The ruffled surfaces are flat across the diameter, and from the center to the peripheral edge, the depth of each valley is equal to the crest of the ruffles, forming a smooth blending wave into one another. The speed radio of the gears depends upon the distance between the axle centers of the slide pin gear and the corresponding pair of ruffled wheel plates. Alternately, the gear assemblies may be provided with auxiliary locking features, to insure the locking of each of the pins at the desired position for maximum interface with the ruffled wheel plates.

In this way an especially gentle and rapid motion is made possible. The crank pins may each be mounted on its own shaft, or they may be mounted together on a common shaft with an offset of 180.degree..

Abstract: A gearing has on its driving shaft a drive means carrier member carrying drive means in the form of pins protruding towards a driven means carrier member fixed to the driven shaft and carrying divergently arranged driven means. The driven shaft is offset relative to the driving shaft so that the circular orbital path of movement of the driven means surrounds the circular orbital path of movement of the driven means. From the drive means always only one single drive means contacts a driven means and only in a portion of the orbital path thereof which portion is more remote from the axis of the driven shaft than that portion of this orbital path arranged nearer to the driven shaft. In the other portions of their orbital path, the drive means pass within the orbital path of the driven means but do not contact these. This results in an increased torque of the driven shaft.
