ROMEY IV. PRI'IT, OF JULIA, WVEST VIRGINIA.
COMBINED LEVEL AND PLUMB.
SEECIFICATION forming part of Letters Patent No. 704,369, dated July 8, 1902.
Application filed March 29,1902. Serial No. 100,574. (No model.)
To aZZ whom, it Duty concern.-
Be it known that I, ROMEY IV. PRITT, a citizen of the United States, residing at Julia, in the county of Greenbrier and State of West Virginia, have invented certain new and useful Improvements in a Combined Level and Square; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention provides a tool for mechanics use embodying a level, plumb, T square, large square, and miter-square, the blades forming the squares being adjustable to various positions and adapted to be secured when positioned.
For a full desciption of the invention and the merits thereof, and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and drawings hereto attached.
While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a tool embodying the invention, the dotted lines showing the brace turned so as to hold the body of the tool in an upright position when used as a level. Fig. 2 is a side View of the tool inverted. Fig 3 is a side View of the tool having the miter-square open. Fig. 4 is a view similar to Fig. 3, showing the blade comprising the T and large squares open. Fig. 5 is a view similar to Fig. 4, showing the blade moved so as to form a T-square with the body of the tool. Fig. 6 is a detail view of the end portion of the stock or tool body having the miter-square. Fig. 7 is a detail section of the opposite end portion of the tool.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
The body or stock 1 of the tool is long and narrow and is comparatively thin and is provided at a point intermediate of its ends with a level 2 and plumb 3, the same being formed by tubes containing an air-bubble and properly arranged in openings formed in the part 1 after the fashion of the well-known spiritlevel and plumb. In order that the body or stock may be supported when resting upon its lower edge,a brace dis pivoted intermediate of its ends and the part 1 and is snugly fitted in a recess formed in the lower edge thereof, the ends of the brace being beveled to engage with corresponding inclined ends of the recess in which said brace is seated, thereby holding the latter flush with the sides of the stock 1 when the brace is closed.
The miter-square consists of a blade 5, adjustable in a slot formed in an end portion of the stock and suitably graduated both for linear and angular measurements. A pivotfastening 6 passes through a slot of the blade 5 and has its end portions supported in openings provided in the parts of the stock embracing the sides of the blade. A thumb-nut '7 is mounted upon the threaded end of the pivot-fastening 6 and can be turned to cause the separated parts of the stock to grip opposite sides of the blade 5 and hold the latter in an adjusted position. The pivotal end of the blade 5 is curved and is graduated to assist in adjusting the blade to any required angle.
The blade 8 of the T square and large square, like the blade 5, is mounted so as to fold within the body or stock 1 and is adapted to be opened and moved so as to form either a T-square or a large square as may be required. This blade 8 is suitably graduated along its edges to denote any required measurement. A fastening 9 connects the separated parts of the stock 1, between which the blade 8 is located, and may be of any construction to admit of clamping the-blades in an adjusted position. A series of openings 10 are formed along the length of the blade 8, and a spring-catch 11, applied to a side of the stock, is adapted to cooperate with the blade and hold the latter in an adjusted position.
When the tool is used either as a level or plumb, it is preferable to hold the blades 5 and 8 within the body or stock, although this is not essential, and the blades may be made to aline with said stock, thereby increasing the length of the stock, whereby greater accuracy in determining the relative position of points may be had. The stock 1 may be 10 catch at one side of the stock to engage with 1 any one of the openings in the blade and hold it in adjusted position, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
ROMEY W. PRITT.
