Description
Patented Dec. 21, 1943l UNITED STATES PATENT OFFICE GAUGING TOOL Steven Koller, Detroit, Mich.
Application July 21, 1941, Serial No. 403,323
Z Claims.
This invention-relates to a gauging tool.
It is an object of the present invention to provide a machinist's square which will permit accurate testing of work being machined.
It is a further object of the invention to provide a checking tool which may be readily fastened to work to leave the operators hands free for the checking operations. l
A further object of the invention is lthe provision of a suitable supporting means for the tool which insures proper contact with the work at all times, and the design of checking surfaces to avoid inaccurate reading.
Other objects and features of the invention having to do with details of construction will be brought out in the following description and claims.
In the drawing:
Fig. 1 is a view illustrating the use of the tool for checking squareness.
Fig. 2 is an end View taken on line 2--2 of Fig. 1.
Fig. 3 is a sectional view on line 3-3 of Fig. 2, showing the relation of the parts.
Fig. 4 is a further sectional view taken on the line 4-4 of Fig. 3.
Fig. 5 is a, section on the line 5--5 of Fig. 1.
Referring to the drawing, a work piece is shown at I in Fig. 1, resting on a table Il. The tool which consists of an L-shaped square comprises a short leg I2 and a long leg I3, and a holding means I4. A gauge I slidable on the table II is used forchecking the condition of the Work, see Fig. 5. A small pin I5a is provided to contact the leg I3 of the square.
Taking up in detail the holding means I4, the short` leg I2 of the square is floatingly mounted between two plates 20. These plates are preferably formed of soft iron having a high permeability. At right angles to each of these plates is a semi-circular plate 2| on which is supported a circular housing 22 formed of non-magnetic material. Between plates 20 is a U-shaped bar 23 formed of a non-magnetic material, such as brass. The leg I2 of the square has a sliding fit in a slot 24 of bar 23. A pin 25 passes through plates 20 and the sides of bar 23, and also through an elongated slot 26 in the leg I2. Three horseshoe shaped magnets 30, 3I and 32, mounted together, straddle a non-magnetic bar 33. A non-magnetic U-shaped member 34 is fastened at each end to the bar 33 and at its base to a cover plate 35.
A stud 36 extends from bar 23 into a centrally located socket with bar 33 so that the magnetic 56 assembly, including the cover 35 and the magnets, may be rotated on the stud. A non-magnetic disc 3l faces the circular surface formed by members 3l and 22 and the base of bar 23. Located in recesses in the base of the bar 23 are spring pressed plungers 38 which bear against the inwardly disposed surface of the leg I2 of the square.
When themagnets are in the position shown in the drawing, the flux lines pass to the plates 20 and set up magnetic forces therein. It will be noticed that the outwardly disposed surface 4U of leg I2 projects beyond the outwardly exposed edges of plates 20, see Fig. 4. When this surface 40 is placed against an iron or steel work piece, as shown in Fig. 1, flux passing through plates 20 will cause the tool to hold to the work. The plungers 38 will be depressed until the surface 40 is flush with the outer edges of plate 23. In any case, the surface 40 will be first to contact the Work and the magnets will draw the plates 20 into contact with the work to hold the square member firmly thereto.
The cross section of the leg I2 is preferably rectangular, the surface 40 being a machined flat surface. The cross section of the testing leg I3 is to be rounded, as shown in Fig, 5, so that a gauge contacting the surface will contact only the highest point. If a square were used, the two edges might cause inaccurate reading as the gauge was passed along the square, as shown in Fig. 1. Once the tool is applied to the work, it will hold by its own magnetic forces and the operator is free to move the gauge I5 to check the condition of the work. When the checking has been done, the gauge can be readily removed by turning the cover plate 35 ninety degrees. This will short magnets 30 and 32 through plates 2| and the center magnet will be disposed in alignment with the base of bar 23. No magnetic forces will pass between the plates 20 and these plates will, therefore, lose their magnetism and cause release of the tool.
Suitable stops are provided on the cover plate to limit the off and on movements.
I claim:
1. In a tool, a holding means comprising parallel plates with high permeability, insulating means between said plates, said plates having face edges in a common plane, a plurality of permanent magnets mounted adjacent said plates, movable to a position where flux from said magnets will enter said plates, and means comprising an L-shaped square having one leg floatingly mounted between said plates, and resilient means urging said leg to a position outwardly from said common plane.
2. In a tool, a holding means comprising a pair of angle plates, each having a. side arranged inv parallel relation with the similar side of the other, the angled portions of each being positioned in a common plane, a. bearing disc positioned flush against the outer surfaces of the angled portions, a plurality of permanent magnets mounted adjacent said plates having pole surfaces arranged to bear on and slide on said disc, said magnets being movable from a posiaaaaasa i0 work piece,
