Specification of Letters Patent.

Patented April 21', 1908.

Application filed December 17, 1906, Serial No. 348,330.

To all-whom it may concern:

Be it known that I, AXEL Orson, a citizen of the United States, residing at Stockett, in the county of Cascade andState of Montana, have invented certain new and useful Improveme'nts in Combination-Tools; and 1 do declare the followin F the'invention, such as will enable others skilled in the art to which it appertains'to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of refer ence marked thereon, which form a part of this specification;

My inventions relates to improvements in carpenter tools; and the object is to provide a combined lumb level, square and rule in one handy 0 cap and efficient tool. This and other objects I attain by the novel conarts illusawmg, in

struction and arrangement of trated in the accompanying which,- 7

Figure 1 is a side elevation of the tool shown as applied upon a piece of lumber for either levehng it u or markin it to be cut at various angles. ig. 2 is a eft hand edge view of Fig. 1.

Referring to the drawing by letters of reference. A-lsa metal late with three straight e es B, O, and D, oi which B and C form a rig t angle or ninety degrees while the edge D form an les of 45 degrees where it unites fges B and O. :The edge B is provided with side ledges or flanges E and'the edge 0 is marked at both sides and at the very edge with inches and fractions of inches increasing from flanges E.

In the plate is cut out a semicircular a erture F, upon the curved edge of Whic is marked a scale of the degrees of one fourth of a circle in sucha position that the th degree comes in a radial line drawn from the center of the half circle to the rectangular corner of the plate. And. from the middle of the straight ed e in the aperture is sus ended in the center 0 the half-circle a plum bob to'be a'full, clear, and

G, whose oint moves close to the scale of degrees. aid plumb bob is suspended bya short cord or string H and a hook I, the 'cord serving to insure full freedom of the bob to hang in a perfectly plumb position, in contradistinction to the much used ivots whose friction hinders free hanging o the bob in similar tools and the book being to make the bob detachable so that it may be easily removed when not needed for some time.

Inusing the tool the scale of inches is used the same as on any ordinary square, and so are the flanges E, which being pressed against .the ed e of a iece oflumber as indicated at J, hol the p ate in such position that the edge 0 will serve as a common square and the edge D as a miter s uare in marking where to cut the lumber. he tool may also be tilted so many degrees and thus enable one to mark for cuttin an desired angle or slanting line. The b0 wil also enable the Workman to ut the timber worked on in an desired position from vertical to horizonta Having. thus described the invention, what I claim as new and desire to secure by Letters Patent, is

A tool of the class described, comprising a metal plate having three corners and three straight edges forming one rectangle and two miter angles, said plate having a semicircular aperture with the middle of the half circle toward the rectangular corner of'the plate,

and a scale of ninety degrees of a circle pointing to the degrees on the scale.

In testimony whereof I aflix my signature,

in presence of two witnesses.
