Abstract: The present invention is a pull-back, windup type spring drive unit with two output shafts capable of transmitting driving force to the front-wheels and rear-wheels. This unit is provided with: a frame; front-wheel and rear wheel output shafts; a drive gear; a spring; a windup gear mechanism; first and second running gear mechanisms connectable to the front-wheel and rear-wheel shafts; and a constant speed mechanism. When one of the output shafts is rotated for winding, switching gear of the windup gear mechanism moves to a mesh position and the rotation of the output shaft for winding is transmitted to the drive gear to wind up the spring. When the drive gear is rotated for running, switching gears of the respective running gear mechanism move to the respective mesh positions to transmit the rotation of the drive gear to each of the output shafts.

Abstract: The initiator (32) has a hollow spool housing (34) with sidewall slots (42,44) and within which is received a shaft (54) to be releasably retained. Spool segments (46,48) are placed within slots (42,44) and have parts extending into the housing bore (50) obstructingly engaging the shaft (54) preventing its removal. A spring coil (82) wound over the spool segments (46,48) holds them in place. Cartridge assembly (62) is releasably secured to the housing (34) and includes a link wire (72) for securing one end of the coil (82). The link wire (72) is destructible by passing an electric current therethrough exceeding a certain value.

Abstract: A mechanical oscillator including a shaft having an endless groove in its periphery, a nut body carried by and slidable along the shaft at the location of the endless groove, and a roller pin carried by the nut body, having a nose portion extending into and engaging a wall of the endless groove and having a tail portion disposed deeply in the nut body. A plurality of anti-friction bearings is carried by the nut body, the bearings carrying the roller pin. The anti-friction bearings include both a ball bearing and a needle bearing, the ball bearing being disposed adjacent the nose portion of the roller pin, and the needle bearing being located adjacent the ball bearing and engaged with a tail portion of the roller pin. The roller pins are carried on two carrier strips respectively disposed at opposite sides of the nut body. The carrier strips and associated roller pins can be removed as a unit, thereby simplifying replacement as required by damage or wear.

Abstract: An auxiliary PTO assembly is designed for attaching a front mounted auxiliary rotary driven hydraulic pump to an OEM truck engine. The PTO assembly includes an auxiliary belt drive pulley which is formed by a ring which is shrink-fitted around a harmonic balancer which forms a portion of an OEM fan drive pulley. A bracket attached to the OEM engine is adapted to hold the hydraulic pump and a plurality of idler and tensioner pulleys. Installation of the inventive assembly is relatively simple and straight forward and entails virtually no modification of the OEM components. The entire PTO assembly including the auxiliary drive belt and the hydraulic pump are accommodated behind the original position of the OEM cooling fan such that the fan shaft does not need to be extended.

Abstract: A variable-speed drive (1) having an input shaft (3), at least one output shaft (4), and a system (5) for connecting the input shaft (3) to the output shaft (4) and enabling the velocity ratio of the shafts (3, 4) to be varied continuously; which system is defined by a first truncated-cone-shaped rotary body (6) angularly secured to the output shaft (4) and defined laterally by a curved convex surface (7) having a given radius of curvature and by a number of second truncated-cone-shaped rotary bodies (8) angularly secured to the input shaft (3) and arranged in a ring about the first rotary body (6). Each second rotary body (8) is defined laterally by a curved concave surface (9) having a radius of curvature greater than that of the convex surface (7) defining the first rotary body (6).

Abstract: A multi-speed transmission for transmitting power between a first shaft and a second shaft includes a plurality of gear sets, a plurality of connector gears corresponding to the plurality of gear sets and a shifting mechanism. Each gear set includes a first gear rotatably disposed about the first shaft, a uni-directional free wheeling mechanism between the first gear and the first shaft, and a second gear coupled to the second shaft. The uni-directional free wheeling mechanism permits the first gear to freely rotate about the shaft when the first gear rotates in a preselected direction relative to the rotation of the first shaft and locks the first gear to the first shaft at all other times. The first and second gears are spaced apart from one another but may be interconnected by one of the plurality of connector gears. Each connector gear is movable between an engaged position and a disengaged position.

Abstract: An operating lever device of the present invention includes housing 3, an operating lever 5 pivotably mounted on the housing 3 by a first support shaft 4, a first link 7 pivotably mounted on the operating lever 5 by a second support shaft 6, an operating cable 8 connected to an end portion of the first link 7 and extending outwardly through the housing 3, and means 9 for restraining the pivotal movement of the first link 7 in a manner that when the operating lever 5 is operated the end portion of the first link 7 may approach the first support shaft 4.

Abstract: In the case of a motor vehicle comprising an operating device for the shifting of a power-shiftable transmission, the transmission can be automatically or manually shifted by way of a selector lever. The device comprises a finger-operated shifting rocker which is arranged in at least one steering wheel spoke, is held on a swivel shaft disposed in a housing and has an adjusting shifting element arranged between two electrical pressure switches. The shifting element comprises a lever which is connected with the housing and is arranged by means of its free end between operating surfaces of switches which are arranged coaxially with respect to one another. With respect to the housing, the shifting rocker can be swivelled about the shaft with a shifting travel in two directions.

Abstract: A transmission device for a vertical blind including a housing, a worm disposed within the housing and having an upper flange, a lower flange, and at least two spiral teeth between the upper flange and the lower flange, each of the spiral teeth having an end gradually extending outwardly from the worm, and a worm gear disposed within the housing and meshed with the worm, the worm gear being formed with a partition across a number of teeth thereof.

Abstract: A table translation apparatus for a wood working machine is disclosed wherein a table can be repetitively moved at a high speed within a small distance to enhance the working efficiency for wood. A pair of front and rear screw shafts are supported for rotation linearly at front and rear portions of a bed extending forwardly and backwardly and driven to rotate forwardly or reversely independently of each other by a motor. A pair of front and rear shuttles are held in threaded engagement with the front and rear screw shafts, respectively. A pair of front and rear side clutches for releasably connecting the table and the front and rear side shuttles to each other, respectively, are provided on the table mounted for forward and backward sliding movement on the bed.

Abstract: A gearshift sleeve actuating apparatus for a stepped automotive gearbox is disclosed. The apparatus comprises a shift rod which can be displaced along its axis. A shift fork and an engaging piece or driver are rigidly arranged on the shift rod. The apparatus is configured as a composite plastic/metal structure in which a metal component, constituting the engaging piece as well as a core for the shift rod, is injection-embedded in a plastic material. The shift fork consists exclusively of the plastic material.
