JOHN T. URBAOI-I, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-THIRD TO JOHN WA VARNEY, OF ALEXANDRIA, VIRGINIA, AND ONE-THIRD TO WM. '1. RUGKLE, OF

BALTIMORE, MARYLAND.-

SQUARE AND BEVEL.

To all whom it may concern:

Be it known that 1, JOHN T. URBACH, citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Squares and Bevels, of which the following is a specification.

This invention comprehends certain new and useful improvements in carpenters tools or appliances and relates particularly to an improved square and bevel.

The invention has for its primary object a simple, durable and efficient construction. of device of this character which may be easily and quickly adjusted so as to serve for a variety of functions or uses, in measuring and laying off work, and the invention consists in certain constructions, arrangements and combinations of the parts that I shall here inafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which:

Figure 1 is a perspective view of my improved square and bevel; and, Fig. 2 is a side elevation thereof, partly broken away, and partially broken out to economize space.

Corresponding and like parts are referred to in the following description and accompanying drawings by the same reference characters.

The stock 1 of my improved square and bevel includes the right angular end 2 of the graduated rule arm 3, and cheek pieces a which may be of wood with metal ends, riveted to the opposite sides of the arm and extending perpendicularly therefrom. The cheek pieces are provided at one end with registering apertures through which a set screw 5 extends, the set screw being designed to clamp the cheek pieces together so as to bind them upon the bevels 6 and 7 which are longitudinally slotted as inclicated at 8 so as to provide for their adjust-- ment to different positions longitudinally and angularly considered. The two bevels 6 and 7 are of different lengths, so that both of them may be used at the same time to lay off certain work, or so that one may be used where the small amount of space would not admit of the other being used and whereby they may be set at different angles so that two different bevels may be laid off without a repeated adjustment of a single bevel arm.

Specification of Letters Patent.

Application filed May 21, 1910.

Patented Aug. 8, 1911.

Serial No. 562,701.

Preferably the smaller bevel 7 is of a size to lie entirely within the recess formed by the end 2 of the arm 3 and one of the cheek pieces 4:, whereby it may be entirely out of the way when not desired for use. Preferably one end of the smaller bevel 7 projects to a slight extent as indicated at 9 in Fig. 1 so that it may be grasped to swing the bevel out to an operative position. In addition to these linear graduations, the arm 3 may be provided with angle graduations as clearly indicated in the drawing, said graduations coacting with either one of the bevels 6 and 7 as required. Preferably the stock 1 carries a spirit level 10.

As best illustrated in Fig. 2, I have provided another auxiliary bevel arm 11 which is pivotally connected at one end to the stock 1, as indicated at 12, being adapted to lie, when not in use, within a recess formed in the stock. This auxiliary bevel arm 11 is designed to co-act with the bevel arm 6 which is graduated to indicate angles on its face joining the auxiliary bevel arm 11, whereby, by swinging bevel arm 6 outwardly, as well as the auxiliary bevel arm 11, as best illustrated in Fig. 2, I may indicate by the use of these two bevel arms, angles greater than right angles, said angles being described by the inner edges of the stock 1 and the bevel arm 6. As an example for the use of the auxiliary bevel arm 7, suppose that it be desired to lay off certain work with reference to a vertical wall in a case where there is only an upwardly inclined beam or other support upon which to lay the instrument. In this event, the arm 7 would be brought into play and laid edge down on such beam, while the stock would be brought to a level position indicated by the spirit level. The clamping screw 5 would then be tightened, the rule arm 3 would lie true against the vertical wall and the bevel arm 6 would then be used to describe on the arm 3 the required angle. The outer end of the bevel arm 6 is provided with a nick 6 to which a pencil may be applied, whereby parallel lines may be laid off in equi-distant relation to each other and also for other purposes which will be apparent to those skilled in this art.

Having thus described the invention, what is claimed as new is:

1. A square and bevel, comprising a rule arm, a stock connected thereto and extended out at right angles therefrom and provided with a recess, a bevel arm pivotally connected to the stock, and an auxiliary bevel arm pivotally connected to the stock and adapted to lie within said recess, the first-nai'ned bevel arm being formed with angle graduations and the auxiliary bevel arm being adapted to co-act therewith whereby to describe with the stock angles greater than right angles, the first-named bevel arm and auxiliary bevel arm having their pivot points arranged at points of unequal distance from the right angularly disposed rule arm.

2. A square and bevel, comprising a rule arm, a stock connected thereto and extended out at right angles therefrom and formed with a recess, a bevel arm pivotally connected to the stock, and an auxiliary bevel arm pivotally connected to the stock and adapted to lie within said recess, the first-named bevel arm being formed with angle graduations and the auxiliary bevel arm being adapted to co-act therewith whereby to describe with the stock angles greater than right angles, the fil'Sl-IlllllQfl bevel arm and auxiliary bevel arm having their pivot points arranged at points of unequal distance from the right angularly disposed rule arm, and another auxiliary bevel arm pivotally and slidingly connected to the stock at a point coincident with the first-named bevel arm.

In testimony whereof, I atfix my signature in presence of two witnesses.
