The present invention relates to a method and apparatus for positioning a tapered member so that the taper of a tapered surface thereof can be verified. The apparatus comprises a first surface having an angle with respect to the horizontal which is equal to the included angle of the shaft to be measured. A vertical surface having an angle equal to one half the included angle of the shaft to be measured is arranged along one edge of the first surface. A plurality of horizontal gauge block surfaces are arranged at predetermined vertical heights with respect to the base of the first angled surface. A gauge block, whose size is determined by the particular shaft to be measured, is secured to an appropriate gauge block surface so that a gauge can be preset to zero with reference to an upper horizontal gauge surface of the gauge block. Thereafter, the member to be measured is placed with the tapered surface resting against the two angled surfaces. The gauge is then moved along an upper portion of the tapered surface to obtain a reading. The readings obtained on the upper portion of the tapered surface of the member are compared with the preset value obtained at the gauge surface to determine whether the taper has been properly machined.
Attachment ears for use with a predetermined assembly of Johansson blocks, with the ears disposed at opposite ends of the assembly, for measurement of an inclination between spaced-apart surfaces of a workpiece. An indicator gage has a stationary stylus to contact a surface of one ear, and an indicator stylus to contact the inclined surface of the other ear and moveable thereon to define an arc with the stationary stylus as a fulcrum to establish an apex reading of the indicator. The gage is transferred to the workpiece with the stationary stylus and the indicator stylus contacting the two spaced-apart surfaces, and the indicator gage is moved about to provide a gage reading to determine a thickness of material to be removed from the workpiece.
A tool for precisely determining the height and setback of a bicycle seat so that the seat can be adjusted to desired parameters. The tool can also be employed to determine the exact height of a bicycle's frame. The tool includes an adapter member that is attached to the bottom bracket spindle of the bicycle after removal of the crank arm. An elongate measuring pole is attached to the adapter member. Measuring indicia are inscribed on the outer surface of the pole. The measuring pole is provided with two components adjustably positioned along the length of the pole. One component is adapted to attach to the frame of the bicycle. The second component includes an adjustable position rod.
A plush toy for an infant, e.g., a ball or the like, has a plurality of rings each having a pair of plush arms of a size to be grasped by an infant. The rings include a first center ring having a center portion with the pair of arms bearing a display of a face on a first surface, and an outer ring defining an open center portion, whereby the display may be glimpsed between the arms of the rings. In a preferred embodiment, the first center ring bears a display of a face on first and second opposite surfaces, and the rings include a first outer ring disposed adjacent the first surface of the center ring and a second outer ring adjacent the second surface of the center ring. A method and toy made by the method are also described.
A support stand for positioning a precision gauge for checking the dimensions of an article. The base is stable having three supporting feet and being heavier than many such support bases. The base is tapered with finger grooves to fit well into the user's hand and provides an adjustment screw which rotates about a horizontal axis so reaction forces are directed downwardly into the support plate rather than creating a shearing, destabilizing force. The adjustment screw has as large a diameter as practical to reduce the magnitude of the tangential force needed to produce rotation and its rotation reacts a nub against the substantially vertical support post to tilt it, and the precision gauge supported thereby. An L-shaped bracket can be inverted to provide increased flexibility in measuring different size articles. Squareness checking rails are provided on the front and back surfaces to enhance the flexibility of using this support stand.
