Patent number: 4349965Abstract: Four alignment housings are mounted on a garage floor adjacent a conventional lift, so that when a vehicle has been elevated by the lift each of its four independently suspended four wheels will register with an alignment chart that is adjustably mounted on the face of each housing. A beam of light is directed through registering openings in each housing and its attached chart toward a mirror releasably mounted on each vehicle wheel. The mirrors reflect the beams back onto the associated charts, which are calibrated to provide camber, caster and toe-in readings. In one embodiment each housing contains a light source (for example a laser) which directs a beam onto a reflecting surface which is inclined at 45.degree. to the horizontal, so that it projects the beam at right angles out of the housing toward the adjacent wheel.Type: GrantFiled: September 17, 1980Date of Patent: September 21, 1982Assignee: Security Trust Company of RochesterInventor: Pierre A. Alsina

Patent number: 4327497Abstract: A graphic vector plotting instrument, particularly suited for marine navigational computations. A cursor disk is surrounded by a concentric compass disk, and both are rotatable about their common center. The cursor disk has a pair of perpendicular cursor lines which intersect at the common center and a plurality of other parallel cursor lines. The compass disk has a 360.degree. compass rose scale thereon. A transparent plotting slide is slidable over the cursor disk and the compass disk and contains scaled markings permitting the plotting and solution of navigational vector problems thereon without the aid of other devices or surfaces or charts.Type: GrantFiled: March 13, 1980Date of Patent: May 4, 1982Inventor: Robert H. Wyatt, Sr.

Patent number: 4274203Abstract: A measuring apparatus in which two casings are connected together each housing a coiled measuring means adapted for being selectively un-coiled and withdrawn from the casing or recoiled and retracted into the casing. A sighting device is provided on one of the casings to sight a target. The sighting means includes a level for determining when the sighting device is sighting along a horizontal line and a second level is provided to indicate when the casings are also appropriately arranged relative to a vertical line perpendicular to the first said horizontal line. Triggers are provided for the two coiled measuring devices and a brake is provided for each of the measuring devices. A digital display is employed and a counting circuit is provided for indicating the amount of measuring means which is uncoiled from the two respective casings. An alarm is provided to indicate when the unwound measuring devices are off line relative to the sighting device.Type: GrantFiled: September 24, 1979Date of Patent: June 23, 1981Inventor: Anthony J. Vasile

Patent number: 4236313Abstract: A technique is disclosed herein for evaluating solar exposure at various points in any one of a number of given geographic locations for any given period during the year in order to determine the most efficient location for a solar collector. This technique may be carried out utilizing a single apparatus which is also disclosed herein and which includes a solar pointing device and the necessary indicia to appropriately orient the pointing device with respect to its environment at the various points selected. Once the pointing device is oriented, it is moved in a solar pointing position in an way which determines the path of the sun between sunrise and sunset for each point. From these paths, the amount of actual solar exposure at each of the points selected can be determined taking into account any resulting obstructions such as trees, rooflines or the like.Type: GrantFiled: December 26, 1979Date of Patent: December 2, 1980Inventor: Roy N. Griffin, Jr.

Patent number: 4057906Abstract: A portable navigational instrument has edge portions which are adjusted so that the instrument's orientation with respect to a vessel can be maintained constant in different positions within the vessel's wheelhouse. Bearings of objects are determined by a sighting arrangement which co-operates with a scale which is set in accordance with the vessel's steering compass bearing, corrected for deviation, whereby the need for a compass on the instrument is avoided. The sighting arrangement can comprise a single visible sight, and/or three such sights enabling horizontal angles between objects to be determined from a further scale, and/or a radio direction finding aerial.Type: GrantFiled: January 23, 1976Date of Patent: November 15, 1977Inventor: Richard Creighton King

Patent number: 3988838Abstract: A device for enabling an artist to achieve correct proportions when drawing to a different scale than that of the object being reproduced. The device employs a flat transparent elongated plate having two parallel sides of unequal length, one straight and interconnecting these sides and being perpendicular to both sides, the opposite end being curved and interconnecting the two sides while being perpendicular to neither side. An elongated rectangular flat transparent arm lies in a plane parallel to the plate and adjacent to the plate and adjacent one major surface of the plate, one end of the arm being pivotally secured to the plate adjacent the straight end and longer side, the other end of the arm extending past the curved end of the plate. The curved end defines the arc of a circle centered at the point of pivot of the arm. Clamping means on the other end of the plate can be manually operated to clamp the arm to the curved edge of the plate in any desired position thereacross.Type: GrantFiled: September 15, 1975Date of Patent: November 2, 1976Assignee: The Raymond Lee Organization, Inc.Inventor: Robert C.
