Through the adjustment of the guide blocks along the crossbar, the cables to the airplane may be varied in length to properly stablize the plane during flight.

Abstract: In an apparatus for sewing articles, such as sewing a slide fastener chain to an opening in an article, stitching of thread to an article is initiated by a manual control and is terminated by an automatic control in response to the sensing of a terminal point, such as the terminal point of an opening, on the article.Article guiding facilities urge folded edge portions of an article toward each other by spring biased members on folding plates.A scroll for receiving and guiding a folded edge portion of an article has an adjustable channel.A linear motion apparatus, such as a dual needle holding mechanism, employs a linear motor driving a camming member which engages a locking member on a movable member to move the movable member to a selected position and to operate the locking member.

Abstract: A rear view mirror for a motor vehicle in which a mirror head is mounted for angular movement about two axes at right angles to each other and is adjustable about these axes by rotation of a single control shaft. Adjustment of the head about one axis is effected by rotation of an eccentric element by the shaft, and adjustment about the other axis is effected by linear movement produced by rotation of a second element such as a scroll cam or screw thread. A lost motion device is arranged between the shaft and at least one of the elements so that a degree of adjustment of the mirror head about one axis can be effected without alteration to the angular setting of the head with respect to the other axis. The lost motion device may be arranged between the two elements or between an additional fine-adjust device and both the elements.

Abstract: A system for balancing a rotary element involving two or more materials of different melting temperatures normally fixed in position relative to the rotary element. Heating of the materials first to a point above the highest melting temperature followed by cooling at optimum balance then reheating to a point above the next highest melting point followed by cooling at optimum balance and repeating the procedure for each material results in vernier balancing action, the masses of the various materials being selected to predetermine their effect on balance.

Abstract: In a gyro horizon type of equipment, roll corrections are fed to the aircraft symbol which is a normally fixed display element and pitch correction is introduced on a movable display element or drum with modification of the position of the display elements of the instrument gyro as a function of an interconnection of the instrument gyro with a gyromaster reference through comparators connected to each of the roll and pitch systems.

Abstract: A knob is used on an adjustment member rotatable about an axis and having a periphery formed with a plurality of radially outwardly open recesses. This member may be the adjustment member of a motor-vehicle seat-angle adjuster. The knob comprises an annular collar closely surrounding the periphery of the adjustment member, a plurality of entrainment formations projecting inwardly from the collar into every other recess, and a plurality of hooks each engaging axially through the remaining recesses with the member. The hooks and the formations together transmit angular force between the member and the knob which is made of synthetic-resin material as one integral piece.

Abstract: A control linkage system is disclosed for simultaneous control of an engine throttle or governor and a hydrostatic transmission from a single control pedal. The system includes unidirectional linkage means including a pair of lost motion links mounted for reciprocal movement at opposed ends of a lever rotatable in either direction by the single pedal. The lost motion links extend outwardly in the same general direction and are coupled at a common pin with the throttle control linkage through a rocker arm. Each lost motion linkage is retractable upon motion of the linkage system in one direction. A second bidirectional linkage means, including an override link, is interconnected to the pedal and a swash plate control member of the hydrostatic transmission.

Abstract: A safety structure for automatically releasing a shoe worn by a cyclist from a bicycle pedal in the event of a collision, a fall, or the like. A structure which connects the shoe, worn by the cyclist during operation of the bicycle, to the pedal is supported by the pedal for movement automatically to a position releasing the shoe from the pedal whenever the cyclist exerts through the shoe on the pedal an abnormal force of the type which occurs during a collision, a fall, or the like.

Abstract: A speed change gear system for providing at least four forward drive speed ranges and one reverse drive speed range includes three planetary gear sets of the single-pinion type, three clutches, and two brakes. As a result of the coupling and uncoupling of the clutches and brakes, the movable elements of each of the planetary gear sets are suitably coupled so as to attain the various speed ranges.

Abstract: A multi-speed transmission for an engine driven agricultural or construction vehicle is comprised of an epicyclic torque-splitting gear arrangement driven by an input assembly. The input assembly, driven by the engine through a drive engagement means, includes a reversing planetary gear arrangement. The epicyclic torque-splitting gear arrangement includes an input member driven by the input assembly, an output member and a reaction member. The reaction member of the epicyclic torque-splitting gear arrangement is drivingly interconnected with a speed reduction means. The speed reduction means is also driven by the input assembly, and is selectively controllable for rotating the reaction member of the epicyclic torque-splitting gear arrangement in one or the other directions relative to the direction of rotation of the input assembly. The speed reduction means is further controllable to stop rotation of the reaction member relative to rotation of the input assembly.

Abstract: An air erected gyro includes an erection-force producing air stream and gravity-responsive valve means whose gate portion is movable across the air stream so as to vary the erection force magnitude. Also included is a compensator means connected for movement with the gate and for also confronting the air stream so as to at least partially counteract air stream induced horizontal coercive effects on the valve means position.

Abstract: A vibration isolation system wherein a vibrating mass such as a helicopter rotor-transmission assembly is spring coupled to a body to be isolated, such as the helicopter fuselage, at a plurality of points. Each coupling point includes, in addition to a coupling spring, a weighted lever arm pivotally connected to the vibrating mass and to the body, with the body-to-lever pivot connection lying between the center of gravity of the arm and the vibrating mass-to-lever pivot connection. The coupling spring is in the form of a torsion spring, e.g., torsion bar, coupled between the body and the lever arm at the pivot connection therebetween. Vibratory forces of a predetermined frequency transmitted from the vibrating mass to the body through the spring are substantially cancelled by inertial forces generated by the lever and applied to the body through the body-to-lever pivot connection, thus isolating the body from the vibrating mass at the predetermined frequency.

Abstract: An energy storing flywheel drive including first and second flywheels rotatably supported in a housing for rotation about a common axis and operatively connected to a common shaft through respectively first and second planetary type traction roller transmissions, the first flywheel being connected to the sun member and the input-output shaft being associated with the planetary members of the first planetary transmission while its outer ring member is mounted in the housing and the second flywheel is connected to the sun member and the input-output shaft is connected to the outer ring member of the second planetary transmission while its planetary members are mounted on the housing thereby to cause, upon rotation of the input-output shaft, rotation of the flywheels in opposite directions, the transmission ratios of said planetary transmissions being so selected as to prevent the generation of gyroscopic forces.

Abstract: A cable actuating lever is disclosed wherein the lever is operable when shifted in any direction within a 360.degree. range. This mechanism is easily attached to the handle bars of bicycles, motorcycles, and similar vehicles where a readily accessible manual control means is required to actuate braking, clutchings or other mechanical operations.Due to its capability to flex in any direction, the danger of breakage, bending, or becoming inoperable by an impact force applied contrary to its normal operating direction is virtually eliminated.

Abstract: A differential axle embodying a differential assembly mounted in a housing arrangement formed of, preferably, die cast aluminum parts and consisting of a central housing portion in which a differential is mounted and tubular portions connected to the sides thereof and extending laterally therefrom and within which the drive axles rotate. The differential unit forming a portion of the assembly consists of a differential carrier which is divided into two parts, with one part having the ring gear of the differential integral therewith and with each part of the differential carrier having hub portions which are heat treated and form the inner races of antifriction bearings which rotatably support the differential carrier within the centrl housing portions.

Abstract: A rotatable knob assembly having a knob easily mounted to the mounting section of an operating member, with the mounting section having two adjacent parts with a first part having a generally elliptical cross section and the other part having a generally circular cross section and with the knob having an open-ended cavity and an upstanding ridge on the inner surface of the cavity surrounding the wall which is of generally the same perimetrical length as the generally equal perimetrical lengths of the two parts of the mounting section. The knob is formed of a material which is capable of being distorted whereby placement of the knob on the mounting section by relative insertion of the mounting section into the cavity causes distortion of the locking ring to pass over the generally elliptical cross section part and the locking ring then returns to its normal shape to engage against the generally circular part of the mounting section and to lock behind the elliptical section.

Abstract: A composite flywheel is shown with concave or conical shapes or combination thereof. Upon rotation at a predetermined speed, the surfaces of the flywheel tend to flatten with a resultant increase in radius measured from the axis of rotation. Such an increase in radius while permitting the disc to flatten has the effect of substantially eliminating radial stresses within the flywheel. A method of forming such a flywheel from commercially available preimpregnated fiber or tapes is also disclosed.

Abstract: A washer is adjustably connected to a driving member of a cam assembly and is coupled to a cam means of the cam assembly.

Abstract: An engine is disclosed having at least one piston in operative connection with a crankshaft. A bearing member which defines an elongated, curved bearing surface, is pivotally attached at one end to an eccentrically-mounted member on the crankshaft. The bearing surface of the bearing member is positioned to be intermittently in power-transmitting, sliding relationship with a connection to the piston such as a piston rod. The bearing member is adapted to be rotatable about said pivotal attachment, for transverse displacement by the piston rod relative to the crankshaft, to absorb any shock generated against the piston and the crankshaft, such as by "engine knock." The bearing member is also adapted to return to its pre-displacement position after absorbing the shock.
