Abstract: A transmission system includes an electrical power unit having a rotor mounted on a shaft which rotates at a predetermined speed and a stator defining a gap with the rotor, and a step-down speed-reducing unit. The speed-reducing unit includes a flexible sleeve extending through the gap and having adjacent one axial end of the rotor a first set of teeth, an eccentric element mounted on the shaft axially adjacent the rotor for rotation within the sleeve so as to impart the eccentricity of the eccentric element to the flexible sleeve as the shaft rotates, and an annular member having a second set of teeth which mesh with the first set, the numbers of teeth in the two sets being different from one another.

Abstract: A compact transmission designed particularly for a self-propelled, walking lawn mower is provided. The transmission is mounted on the deck of the mower behind the engine and is connected to a power take-off shaft of it. The transmission has two forward speeds and is shifted by a short finger-operated shift lever extending rearwardly. The transmission is compact, light in weight, and low in cost. These are achieved, in part, by the gears being arranged to occupy a minimum space and a one-piece shifter fork and guide plate being made of plastic material and assembled through an opening in the top of the transmission housing. The transmission housing also can use either a horizontal or a vertical input shaft with minimum change in design.

Abstract: Transmission for tractors comprising an input shaft rotatably supported by a casing having means defining openings therein, a second speed change shaft disposed coaxially with the input shaft and rotatably supported at its opposite ends by further means defining openings in the casing, and speed change gears positioned outside the casing to operatively connect the input shaft and a first speed change shaft.

Abstract: A known family of multi-speed constant-mesh gear reversible powershift transmissions has a basic structure that includes a plurality of drivingly connected shafts, with all of these shafts lying in a common plane. A plurality of gear trains selectively drives the output shaft at various speed ratios, and pluralities of clutches are used for connecting several of the shafts and for connecting various ones of the gears to various shafts for conjoint rotation therewith. The improvement resides in the modification of an inline transmision to a drop-type transmission which permits the interposition of a power takeoff shaft that is operatively connected to and axially aligned with the input shaft.

Abstract: An automotive transmission with three or four stages corresponding to as many forward speeds, established by the activation of respective hydraulic coupling elements via associated electrical valve-operating switches, includes an individual delay network in the energizing circuit of each valve-operating switch for modifying its response time in dependence on load and on the direction of shift. By this modification an upshift under load or a downshift under pull proceeds with substantially immediate activation of one coupling element upon deactivation of another coupling element, whereas under other circumstances (downshift under load or upshift under pull) an appreciable hiatus occurs between deactivation and activation to take advantage of the intervening speed change.

Abstract: A plastic chair which is assembled from only several unitary pieces, some of which can be identical to each other. The chair seat takes the form of a unitary seat-back shell of molded plastic material. The base structure takes the form of two molded plastic pieces having male and female connecting portions to permit joining the pieces of the base merely by fitting them together. Connecting flanges on the seat-back shell permit securing the seat to the connecting portion of the base. The base pieces are secured together by ultrasonic welding and the seat is ultrasonically welded to the base. The method of making the chair includes molding the several pieces from a colorant containing plastic and securing the pieces together. Each leg includes a plurality of webs to permit cutting the legs so a chair of a desired height is obtained while simultaneously obtaining floor engaging glides. Strengthening ribs and rigidity to the chair, and the plastic can include glass fiber reinforcing for additional strength.

Abstract: Window fastener having a rotatable gear engaging an actuating member formed with a rack and a method of installing.

Abstract: Window hardware for driving a latch rod, especially for insertion in the edge of casement windows, doors, etc., wherein the back side is fastened on a track, consisting of a drive housing having two housing parts in which is positioned a turnable member which can have the shape of a pinion, the turnable member engaging the latch rod fitting which extends through a guide canal in the drive housing and is guided and movable longitudinally on the inverted track.

Abstract: A draw and pull latch consisting of a base plate for attachment to a cabinet, a body pivoted at one end on the base plate and normally covering the base plate, and a draw and pull nose pivoted on the body parallel to and spaced from the body-base plate pivot.
