COMBINATION BEVEL FINDER AND SQUARE.

Application filed February 4, 1920. Serial No. 356,154.

To all whom it may concern:

Be it known that I, Josnrn A. LULAY, a citizen of the United States, residing at Scio, in the county of Linn and State of Oregon, have invented certain new and use ful Improvements in Combination Bevel Finders and Squares, of which the following is a specification.

This invention relates to combination bevel finders and squares and is principally used for framing jack rafters for a square corner building. i

A principal object of the invention is to construct a tool having relatively movable blades from which angles of cutting rafters may be found without calculatlon and only upon a determination of the incline or pitch of the rafter.

With the above and other objects in view, 2 this invention consists of certain novel combinations, arrangements and constructions of parts as will be hereinafter more fully set forth.

In the accompanying drawings, 2 Figure 1 is a side elevation of my invention showing same partly in section.

Figure 2 is a top plan view of my invention, and

. Figure 3 is an end elevation of my invention, and

Figure 4; is a section taken on the line 44 of Figure 1 looking in the direction of the arrow.

By referring to the accompanying drawing it will be seen that this device consists of the handle which is constructed of the bar 1 and the slidable bar 2 mounted thereon. The slidable bar 2 is provided with a slot 3 intermediate its ends so as to receive the bolt 4: which also passes through an aperture provided in the fixed bar 1. This bolt i is provided with a'nut 5 so that the slidable section may be moved when same is loosened and held in a desired position when same is tightened. Both bars 1 and 2 are provided with elongated slots 8 extending from one end thereof between which are received the blades 6 and 7.

The blade 6 is pivotally attached to the end of the sliding bar 2 by means of the pin 9 and is also attached to the fixed bar 1 by means of the pin 10 which is adapted to slide within the slot 18 provided in the blade 6. The blade 7 is pivotally mounted within the slot 8 of the sliding bar 2 by means of a pin 11 so as to be situated a spaced distance from the end thereof. This blade 7 is also attached to the fixed bar 1'by means of the pin 12 which is adapted to slide within the curved slot 1 1 provided in the blade.

In order to prevent lateral movement of the bars 1 and 2 in relation to each other and also to prevent the same from pivoting upon the bolt L it will be seen that I have provided the fixed bar 1 with a projection 15 which is adapted to fit within the slot 3. This projection 15 is substantially square in cross section thus preventing the pivoting of the bar 2 upon the bar 1. It will also be readily seen that the extension of the blade passing through both of the slots 8 will also prevent such movement.

In order to set the square fordifferent pitches, it will be seen that the set screw at will be loosened, whereby the bar 2 may be shifted, thus allowing the blades 6 and 7 to move so as to be set at the desired pitch. The set screw will then be tightened and the device is ready to be used. It will also be noted that I have provided the slot 1a in the blade 5 in a substantially arcuate shape so that it will vary sufficiently to give the side out to fit the hip or valley rafter when the first blade 6 is set at the desired angle or pitch.

Having thus described my invention it will be seen that I have produced an efiicient combination bevel finder and square which may be especially used to frame jack rafters for a square cornered building and at the same time may be readily used for cutting angles of rafters without calculation and only upon a determining of the incline or the pitch of said rafter.

Having thus described my invention what I claim as new is I 1. A device of the class described co1nprising a fixed bar and a slidable bar mounted thereon, a blade pivotaily mounted upon one end of said slidable bar, said blade provided with a slot, 2. pin passing through said slot and fixed to said fixed bar adjacent one end thereof, and another blade pivotally mounted on said slidable bar a distance from said first blade and provided with a curved slot, a pin situated on said fixed bar and adapted to pass through said curved slot for the pur pose specified.

2. A device of the class described co1nprising a pair of bars in slidable relation with each other, one of said bars being provided With a slot, and a pair of blades pivoted to one of the bars in spaced relation and passing through the slot of the other bar.

3. A device of the class described comprising a primary bar and a secondary bar situated in slidable relation to each other, said secondary bar being provided With a slot. a plurality of blades pivoted to the primary bar and passing through the slot in the secondary bar, said blades provided With slots, and pins situated in the slot of the secondary bar and passing through the slots in the blades.

4:. A device of the class described comprismg a primary bar and a secondary bar, said bars being in slidable relation to each other, means for holding the bars in adjusted position, said secondary bar being provided With a slot, a plurality of blades pivoted to the primary bar and passing through the slot of the secondary bar.

5. A device of the class-described comprisinga primary bar and a secondary bar, said secondary bar being provided with a slot, said bars being mounted in slidable relation to each other, means for holding the bars in adjusted positions, a plurality of blades pivoted to the primary bar and passing through the slot of the secondary bar, said blades being provided With slots, and pins extending transversely of the slot in the secondary bar so as to pass through the slots in the blades.

In testimony whereof I affix my signature in presence of two Witnesses.
