oolvlBlNEDSQUARE AND BEVEL.

To all whom it may concern:

Be it known that I, ARTHUR HAAG, a y'citizen of the United States, residing at New York, in the State of New York, have invented certain new and useful Improvements in a Combined 4Square andl Bevel ,and I do declare the following to be a full, clear, and exact vdescription of the invention, such as will enable others skilled the art to which it appertains to make and use the Same.

space.

y The above and other objects, which willappear as the nature of my invention isbetter understood, are accomplished by means of the 4 construction illustratedin the accompanying` drawings, in whichj Figure 1 is a perspective view of my improved combination square and bevel, showing its bladg` in full lines in its closed position and in dotted lines in its several open positions to permit its use either as a square ormiter-bevel. Fig. 2l is a vertical transverse sectional view taken on the line 2 2 in Fig. 1, the blade being shown in vits open position. Fig. 3 is a detail sectional view through the pivot and locking-lug of the blade, and Fig. `4

is a detail view of one end of the blade.

Referring to the drawings by numerals, 1 denotes the handle or body portion of my improved combinationsquare and bevel, which is preferably formed from a single piece of sheet metal by bending the same centrally and longitudinally upon itself, as at 2 ,l to form two parallel sides3, and bybending the side edges of said' sid es outwardly in opposite directions at right angles to said sides 3 in order to form flangesg4, as clearly shown in Fig. 2 of the drawings. The opening 5 thus formed in the body or handle 1 is adapted to This blade,

pivotally mounted at one end of the bodyv 1 etween its 'sides 3, so that when the toolis not in use it may be folded within said body,

as shown in 1.

between the b ade and body. is eHected, as clearly shown in Fig. 3 of the drawings, by

formingalining pivot-openings 7 in the sides4 3 anda similar opening 8 in the inner end of the blade 6 in order to receive a hollow or tubular rivet 9, which forms the pivot of said blade. Said rivet is of tubular form to receive a clamping-bolt 10, which is adapted to clamp a lug 11, which locks the blade in its adjusted position. lThe lug 11 has an inwardly-projecting end 12, which is adapted to pass through an aperture 13, formed in one of the sides 3 of the body, and into any one of The pivotal connection a series of recesses 14, which are arran ed ra- -dially around the pivot-opening 8 in t e end of the blade 6, as clearly shown in Fig. 4 of `the drawings. Said lug 1 1 has the' inner face of its opposite end recessed, as shown at 15, to receive the curved projection 16 of the rivet 9, and said projection is formed `with an enlarged concentrically-disposed recess 17 to receive a spring 18, which surrounds the bolt 10. The latter, as clearly shown in Fig. 3 of' the drawings, extends through the rivet -9, the spring 18, the lug 11, and has upon-its outer screw-threaded end a winged clampingi nut 20, which is adapted to force the lug 11 downwardly to cause its ends 12 to enter one of the recesses 14 in the blade.

It will beseen that when the nut 20 is unscrewed the spring 18 will force the lug y11 outwardly to disengage its end' 12 from one of the recesses 14, so that the blade 6 may be swung to any ofthe positions shown in Fig. 1 and then secured therein by tightening the screw 20.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring amore extended explanation.

Various changes in the-form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacriiicing any of the advantages of this invention. v y

Having thus described my invention, what I claim as new, and desire'to -secure byLetters Patent, is f v 1. A combination square and bevel com- IOO prising a body having a longitudinally-ex- IIO ing and adapted to aline with said aperture in the body, apivot passed through said pivotopening in the body and blade, a lug upon said pivot adapted to extend through said aperture in the body and to enter one of said recesses in the blade, and a clamping device upon said pivot, substantially as described.

2. A combination square and bevel comprising a body having a longitudinally-extending recess, a pivot-opening and an aperture in one face adjacent to said pivot-open ing, a blade formed with a pivot-opening and recesses arranged radially around said opening and adapted to aline with said aperture in the body, a tubular pivot extending through said alining pivot-openings in the body and blade, a screw bolt extending through said tubular pivot, alug apertured to receive said bolt and having a projection adapted to pass through the aperture in said body and to enter one of the recesses in said blade, a spring for forcing said lug outwardly and a clamping-nut upon the outer end of said bolt, substantially as described.

3. Adevice of the character described, cornprising a hollow U-shaped body formed from a piece of sheet metal by bending it centrally and longitudinally upon itself to form parallel sides andl by bending its sides longitudinally in opposite directions to form right-angular ilanges, and a foldable blade mounted between the parallel sides of said body.

4. A folding square and bevel comprising a hollow U-shaped body formed from a piece of metal by bending it to form parallel sides and right-angularly-projecting anges extending longitudinally along said sides, said sides being formed with alining pivot-open* ings, and one being formed with an aperture adjacent to its pivot opening, a fold able blade formed with a pivot-opening and a series of recesses arranged around said opening, a tubular pivot passed through the pivotopenings in said body and blade, a screwbolt passed through said tubular pivot, a locking-lug upon said bolt and formed with a projection adapted to project through the aperture in said body and into one of the re cesses in said blade, a spring upon said bolt between said lug and said pivot, and a clamping-nut upon the outer end of said bolt, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ARTHUR HAAG.
