JAMES A. DUNAGAN, OF TAYLORS, SOUTH CAROLINA.

COMPOUND TOOL.

Specification of Letters Patent.

Patented Apr. a, rare.

Application filed February 18, 1916. Serial No. 79,209.

To all whom it may concern:

Be it known that I, JAMES A. DUNAGAN, a citizen of the United States, residing at Taylors, in the county of Greenville and State of South Carolina, have invented certain new and useful Improvements in Gompound Tools; 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 relates to new and useful improvementsin compound tools and the principal object of the invention is to provide a combination square, level, plumb and gage.

Another object of the invention is to provide a tool which is arranged so that the blade of the square may be folded into a pocket to enable the device to be readily transported.

A further object of the invention is to provide a gage in which the square blade forms a handle thereby facilitating the manipulation of the device.

With these and other objects in View, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a fragmentary perspective view of a building illustrating this improved device used as a gage.

Fig. 2 is an enlarged View partly in section of the tool.

Fig. 3 is a perspective View of the tool.

Fig. 4 is a sectional view on line 4-4 of Fig. 2, and

ig. 5 is a transverse sectional view on line 5-5 of Fig. 2.

Referring to the drawings the numeral 1 designates the main body portion of the device consisting of a bifurcated block 2 forming a pair of legs 3 and 4. The bifurcation is adapted to receive the Weather-boarding of a building as illustrated in Fig. 1 and it will thus be seen that the legs are placed to straddle the weather-boarding. A slot 5 extends through the leg 3 of the device throughout its entire length and partially into the block 2 asillustrated in Fig. 2 and pivotally mounted in this slot is the blade of the square which will be more fully hereinafter described.

The blade above referred to is designated by the numeral 6 and consists of a strip of metal having an opening in one end which alines with suitable openings in the legs 3 to receive a pivot pin 7 by means of which the blade is pivotally mounted between said legs. The body 2 is provided with a cut away portion 8 and the blade is formed with a nick 9 which when the blade is folded registers with the recess or cut-away portion 8 and allows for the insertion of the thumb or finger nail into the nick for moving the blade to open position. In order to hold the blade in either open or closed position, a suitable leaf spring 10 is secured on the inner face of the legs 3 in any suitable manner and at the inner end of said leg while the outer end of the spring is left free to engage the flat portion of the blade 6.

Formed in the body 2 is a circular opening 11 and mounted in one side of said opening is the tube 12 constructed in accordance with the ordinary type of spirit level tube so that the device may be used as a plumb. In order that the device may be used as a level, a similar tube 13 is secured in the inner face of the leg 4 and it will thus be seen that a combined square, level and plumb is provided.

When the device is used as a gage it will be seen that the blade 6 is swung outwardly on the pivot 7 as illustrated in Fig. 1 and the same is slipped over the edge of a strip of weather-board and pressed against the corner board of the building or against the door or window frame and then a line is drawn down the weather-board at the proper point and it will be seen that the same will properly aline with the inner edge of the corner board and indicates the point where the weather-board is to be cut ofi. It will be understood that if so desired the blade 6 may be swung on its pivot so as to force the spring 10 inwardly to frictionally engage the weather board and hold the gage in place during the operation of the markm While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claim.

What is claimed is In a compound tool of the class described, a body, said body being bifurcated to form a slot and a pair of parallel legs of equal length, one of said legs being provided with ed to slip over a board to form a gage and a slot extending in aplaneat right angles to the blade being adapted to provide a handle said first mentioned slot, said second slot exby whiclrthe device may be readily held. tending thewhole length of saidleg, ablade In testimony whereof I afiix my signature 5 pivoted in said slotteld leg and arraifiged to in presence of two Witnesses.
