Abstract: A device for storing dental floss and paying the floss out is disclosed, which device provides three separately-usable strips of dental floss for use to floss teeth. The three strips form a U-shaped loop, and are tightened, or tensioned, for use by a tensioning means made up of an axle with a slot formed at each end, through which portions of the first and third strips of floss pass, which first and third strips are parallel to each other. The axle is mounted for conjoint rotation with a ratchet wheel which is allowed rotation in only one direction by an associated pawl. A thumb wheel mounted for rotation with the ratchet wheel and axle is rotatable by the user of the device to continually tension the strips of floss for use, which rotation of the thumb wheel is easily done by one hand of the user.

This ensures a continued pressure between the boss and the shaft which can result in firm retention of the pulley to the shaft, notwithstanding the inherent dimensional instability of polymeric material.

Abstract: A new and improved aligning rod connector provides for securement in and to end alignment of rod sections (i.e., to fishing rod sections) by employment of a D-shaped shaft member affixed to one rod section and inserted into a chamber member with D-shaped bore, the latter member either an outwardly conforming with shaft D-shape or an outward symmetrical with rod shape, affixed to a second rod section end. The bore's three-fourths arcuate wall and one-fourth flattened surface of either outwardly differently configured chamber member is longitudinally coextensive from entrance to bottom thereof, and the three-fourths arcuate wall and flattened one-fourth surface of the shaft member is longitudinally coextensive from end to end, each member dimentioned to provide optimum frictional engagement in the radially outward pressing of said shaft against chamber bore, creating high intensity of frictional grip and suction, thereby precluding movement and dislodgment.

Abstract: The sub-assembly includes a telescopically arranged rotatable driving shaft and rotatable driven shaft. Both shafts are substantially triangular in cross-section. A spring provides a pre-determined spring force having a magnitude to permit one shaft to slide within the other shaft. The complementary triangular shapes of the shafts causes the torque from the driving shaft to be transmitted to the driven shaft without rotational lash.

Abstract: An improved forms feed mechanism for bidirectionally moving an edge perforated record material, while maintaining the same relative position between the drive shaft and the driven member in both directions of drive shaft rotation, so that printing may be effected in both directions. This may be accomplished by biasing the driving and driven surfaces toward one another.

Abstract: An agricultural machine with a frame on which tool rotors are mounted on upright shafts in a row extending across the direction in which the machine travels. The rotors are driven by a horizontal driveshaft that is segmented and interlocked by couplings. Each segment of the driveshaft is a component of one of the angular gears that drive the tool rotors. The horizontal driveshaft is coupled, through a coupling device that is inside the housing of a main train mounted on the frame, with the output gearwheel of the main train and hence driven by it. Guides for aligning the central axis of the components of the driveshaft with the center line of the output gearwheel of the main train are positioned in a known way at least between the main train and the gears of a tool rotor that are immediately adjacent to it. The coupling device has a coupling component that is rigidly attached to the components of the driveshaft that extend into the main train.

The fastening by which said arc segments are joined provide integrity and rigidity for the hoop and maintain the orientation of the entire hoop in a single geometric plane.

Abstract: A quick release, high torque coupling for interconnecting the bit and drive member in a mine roof drill has axial-locking and torque-transmitting structure integral with the drill members. A plug on the drive member is adapted to be releasably received within a mating socket in the bit and has an axial-locking segment on its outermost end complementally configured with respect to an acircular constriction in the socket to permit insertion of the axial-locking segment into the socket beyond the constriction. A torque transmitting segment on the plug cooperates with the constriction to limit relative rotation of the bit and drive member between oppositely directed torque-transmitting positions. In one of the torque-transmitting positions, the constriction and axial-locking segment are misaligned such that the plug is restrained against axial retraction from the socket.

In one embodiment both the bore and joining portion have mating, non-circular polygonal cross sections. In that embodiment, radially expandable fasteners are located in the vicinities of corners of the polygonal cross section of the joining portion of the shaft. In another embodiment, the bore in the hub and the joining portion of the shaft have circular cross sections, and at least one radially expandable fastener is located on the circumference of the joining portion of the shaft. In both embodiments, each fastener runs parallel to the axis of the shaft, and the longitudinal axis of each fastener is disposed within the perimeter or circumference of the joining portion of the shaft.

Abstract: Any suitable strip material, including cold-rolled steel, is stamped to establish first and second laterally extending portions interconnected by a connecting segment, with a locating hole located midway between the free or distal ends of the laterally extending portions. The connecting segment is sized so that no dimension of the connecting segment as measured from the center of the locating hole exceeds a preselected dimension corresponding with the diameter of a shaft with which the adapter is to be used. The central connecting segment may or may not be symmetrically positioned relative to a center reference line extending longitudinally along the laterally extending segments. One or more laterally extending marginal edges of the laterally extending sections may be tapered in order to permit overbending or overforming of the sheet material.

Abstract: A TV tuner has a housing and a rotating channel selector shaft mounted on the housing. There are a plurality of individual support members positioned by and mounted on parallel flatted areas of the shaft, which flatted areas vary in size to assure correct placement of the support members. Individual coil strips, each carrying a tuning screw, are fixed to the shaft assembly. A simplified clutching arrangement for controlling adjustment of the screws utilizes a coil spring to provide the initial force for moving a pinion gear into operating engagement with the tuning screws. The tuning screws are held by resilient arms which bias the head of the screws toward the shaft to thus firmly maintain the screws in any adjusted position. Each of the coil strips have contacts extending outwardly from one side and positioned to be in electrical and mechanical contact with cantilever spring members fastened to a printed circuit board which in turn is held by the housing.
