Abstract
Abstract A sine device comprises modified standard fixtures found in every workshop and which can be assembled to form a sine table having a greater range of tilting movement than commercially available sine tables. The sine device comprises a first angle plate having a horizontal leg and a vertical leg, and a second angle plate, constituting a tilting table, having a vertical leg pivotally mounted on the vertical leg of the first angle plate for tilting about a horizontal axis. Pin means are disengageably insertable in apertures in the vertical leg of the first angle plate to serve, either alone or in combination with gauge blocks, as references and supports for the tiltable table in any angularly adjusted position of the table. The horizontal leg of the table may be formed with inverted T-slots and apertures whereby various components may be adjustably positioned thereon, such components including, for example, a commercial sine table, a vise, or the like. The vertical leg of the table may be formed with a suitable scale of anuglar graduations and a circular series of apertures to receive locating pins engageable in a locating aperture in the vertical leg of the first angle plate. All or most of the elements are usable separately and independently of each other.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
349 words
A sine device comprising, in combination: an angle plate including a horizontal leg and a vertical leg each having a generally planar configuration and fixed perpendicularly to each other; a tiltable table including a planar base plate having generally parallel opposite surfaces and a bearing plate fixed to said base plate in a position extending generally perpendicular thereto; means for adjustably mounting said table upon said vertical leg with said base plate extending therefrom on one side thereof, said mounting means extending through said bearing plate and through said vertical leg to define a horizontal axis of rotation parallel to said base plate surfaces about which said table may be tilted to any one of a plurality of operative angles relative to said horizontal leg, and being operative to releasably secure said table at any of said operative angles; apertures selectively located in said vertical leg each spaced an equivalent distance from said horizontal axis; pin means adapted to be removably inserted in said apertures and to extend outwardly from said vertical leg on the same side thereof as said base plate; and a plurality of gauge blocks; said apertures being located to enable direct abutment of said pin means inserted therein with the one of said surfaces of said table nearer said horizontal axis to support said table in particular ones of said plurality of operative positions; said gauge blocks being configured and sized to enable insertion thereof between said pin means and said nearer one of said surfaces of said base plate to fully occupy any space therebetween and to thereby enable support of said base plate by said pin means when said base plate is located in operative positions other than said particular ones wherein said nearer one of said surfaces of said base plate is in direct abutment with said pin means, said gauge blocks each having a predetermined gauging dimension which is equivalent to the product of a trigonometric function of the operative angle at which said tiltable table is to be located and the distance between said apertures and said axis of rotation.

A sine device comprising, in combination: an angle plate including a horizontal leg and a vertical leg each having a generally planar configuration and fixed perpendicularly to each other; a tiltable table including a planar base plate having generally parallel opposite surfaces and a bearing plate fixed to said base plate in a position extending generally perpendicular thereto; means for adjustably mounting said table upon said vertical leg with said base plate extending therefrom on one side thereof, said mounting means extending through said bearing plate and through said vertical leg to define a horizontal axis of rotation parallel to said base plate surfaces about which said table may be tilted to any one of a plurality of operative angles relative to said horizontal leg, and being operative to releasably secure said table at any of said operative angles; apertures selectively located in said vertical leg each spaced an equivalent distance from said horizontal axis; pin means adapted to be removably inserted in said apertures and to extend outwardly from said vertical leg on the same side thereof as said base plate; and a plurality of gauge blocks; said apertures being located to enable direct abutment of said pin means inserted therein with the one of said surfaces of said table nearer said horizontal axis to support said table in particular ones of said plurality of operative positions; said gauge blocks being configured and sized to enable insertion thereof between said pin means and said nearer one of said surfaces of said base plate to fully occupy any space therebetween and to thereby enable support of said base plate by said pin means when said base plate is located in operative positions other than said particular ones wherein said nearer one of said surfaces of said base plate is in direct abutment with said pin means, said gauge blocks each having a predetermined gauging dimension which is equivalent to the product of a trigonometric function of the operative angle at which said tiltable table is to be located and the distance between said apertures and said axis of rotation.
Claim 3
Dependent Claim
59 words
A sine device according to claim 1, comprising means for mounting a sine table on the further surface of said base plate including means forming a pivoting axis for said sine table, said pivoting axis extending parallel to said further surface of said base plate whereby said sine table and said device comprise, in combination, a compound sine table.
