Mounting Spirit Levels.

UNITED STATES PATENT FFICE.
SYLVESTER J. SHERMAN, OF NEW YORK, N. Y.
MOUNTING SPIRIT-LEVELS.
Specification forming part of Letters Patent No. 9,867, dated July 19, 1853; Beissued July 1, 1856, No. 374..
T0 alt whom it may concern:
Be it known that I, SYLVnsTnn J. SHER- MAN, of the city, county, and State of New York, have invented a new and useful Improvement in Levels for the use of Mechanics; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being made to the annexed drawing, making a part of this specification, which is a View in perspective of my invention as applied.
My invention consists in the combination of a spring-catch with the usual spirit level to enable it to be readily attached to the edges of squares, rulers, and other tools or implements of the artisan for ascertaining vertical, horizontal or other right lines. Thus one spirit level can be made to subserve the purposes of many and thus too the insertion as a fixture of such in the tools above named is rendered unnecessary.
In constructing my levels I make the box as usual, one side truly planed below the projecting bearers (a). At (1)) I fasten a spring-catch, having one end bent at an angle outward from the instrument, as
clearly shown. To apply the instrument to a square or ruler, press the edge within the spring and force it up against the side of the level until the bearers (a) both rest upon said edge, as seen in the figure and if the edge be straight a truly horizontal line may be found. The instrument is retained in place by the adhesion produced by the pressure of the spring.
What I claim as my invention and desire to secure by Letters Patent is,
The spring catch to hold the level in place upon the square or ruler, in combination with the bearers, the latter being so formed in respect to the level that when they are placed upon a horizontal line the bubble will be in the middle of the glass, and that thus a horizontal or a vertical line may be ascertained from a ruler or from a square when said level is attached substantially as set forth herein.
S. J SHERMAN.
