Speccation if-Letters Patent.
Patented Oct. 1S, 1921.
Application filed August 21, 1920. Serial No. 405,040.
To allv whom 'it may concern.'
Be it known that. I, F REDERTCK MA'rsoN, a citizen of the United States, residing at Redlands, inthe county of San Bernardino and tate of California, have invented new and useful Improvements in Squares, of which the following is a specification.
This invention relates to improvements in squares, the principal object of the invention being to provide a combined try-square and bevel square which may be folded ,so that it can be carried in a pocket and will occupy a small amount of room in the tool chest.
Another object of the invention is to make the device adjustable so that it can be used for different purposes, such as a miter square, laying off different pitches and angles and the like.
A further object of the invention is to pro*- vide indicating means in connection with the adjustable means so that the parts of the square may be placed on an angle of any desired degree.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a face view of a square constructed in accordance with my invention.
Fig. 2 is a view of the opposite side thereof.
Fig. 3 is an edge view.
Fig. d is a longitudinal section with the blade in closed position.
Fig. 5 is a view showing the square being used for finding bevels.
Fig. 6 shows the square in use for laying out mortises.
Fig. 7 shows a square set for laying out a 45 degree miter.
Fig. S is a detail view in plan of the indicator dial and dish, and Fig. 9 is a perspective view of the pivot bolt.
In these views l shows the head of the square and 2 the blade thereof. "The head is provided with the longitudinally extending slot 3 which passes through one end and one side of the head and through the other side a distance slightly less than the width of the blade. The closed side wall of the slot forms a shoulder t which is adapted to be engaged by the edge of the blade to hold the same-at right angles to the head as shown in Figs. l and 2. This blade is provided with a centrally arranged slot 5 which has its ends spaced from the ends of the blade and the walls of the slot engage the rectangular part 6 of the bolt 7 which pivotally connects the blade with the head. The bolt, passes through the head adjacent the slotted end thereof and is rotatably held therein by means of the wing nut 8 engaging one end of the bolt and the slotted nut 9 engaging the other end. Said nut 9 lits in a countersunk opening in the bottom of the head and is caused to move with the bolt by means of the pin 10 which passes through a hole in the end of the bolt and engages the slot in the nut. lt will thus be seen that by loosening the wing nut the blade can be moved into any desired position and then by tightening the nut the blade will be clamped between the two parts of the head. A dial ll is formed onthe face of the head concentric with the opening through which the bolt passes and an indicator disk l2 is secured to the bolt to coperate with said dial. This disk has a square opening therein to receive a square part 7 on the bolt so that it will move with the bolt. This disk is placed under the wing nut 8 and has a mark 13 thereon for coperating with the marks on the dial. The blade is provided with the usual indications and it may have one corner eveled as at 14;, and the head is also provided with a beveled corner so that the device can be used on obtuse angles, as shown in Fig. 5.
lt will thus be seen that by adjusting the blade relative to the head the square can be used for different purposes or the blade can be placed in the slot in the head so that the entire device can be placed in the pocket or a tool chest. As the dial is marked with the degrees of a circle the blade can be placed at an angle of any desired degree by adjusting the parts in connection with the dial. Figs. 5, @and 7 show some of the various uses to which the device may be put.
It is thought from the foregoing description that the advantages and novel features 1 of my invention will be readily apparent.
l desire it to be understood that I may make changes 1n the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim.
What I claim is A device of the class described comprising a head having a slot therein extending through oneJ side, one end and a portion of the other side, a blade pivotally and slidably mounted in the head and having its major portion occupying the slot When the device is in folded condition and the Wall of the partly closed side of the slot forming a shoulder at its end for holding the blade at right angles to the head when the device is used as a square, clampingmeans for holding the blade in adjusted position, such means consisting of a bolt passing through said head adjacent its open end and having a rectangular part located in the slot and the blade having a slot therein for receiving the rectangular part7 a dial on the head, an indicator on the bolt for coperating With the dial and a clamping nut for holding the blade in adjusted position.
In testimony whereof I aHX m signature.
FREDERICK ATSON.
