COMBINATION-SQUARE Specification of Letters Patent.
Patented Oct. 22, 1907.
Application filed February 8, 1907. Serial No. 356,462,
To all whom it may concern:
Be it known that I, WARNER Ronnn'rs, a citizen of the United States, residing at Taloga in the county of Dewey and 'l.erritory of Oklahoma, have invented cer tain new and useful Improvements in Combination- Squares, of which the following is a specification.
The object of my invention is to provide an improved combination of a true tri-Ineter and polygon square, a T-bevel protractor and inclinometer, being adapted for all the uses to which any one of these devices is individually designed, and embodying them all in the one article which is of simple and durable construction, and which will be efiicient in operation and susceptible of convenient manipulation.
The invention consists in certain constructions and arrangements of the parts hereinafter described and particularly pointed out in the appended claims.
For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the-following description and accompanying drawings, in which:
Figure 1 is a plan view of my improved combination square. Fig. 2 is an edge view thereof, partly broken away.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
Referring to the drawings the numeral 1 designates the stock which is pivotally mounted near one end at the vertex of the right angle triangle 2 which is provided as shown with the graduated blade 3 laid off in linear graduations.
Within the triangle 2 and preferably formed inte grally therewith is uniformly graduated segment 4 laid off at its outer edge in degree graduations up to 90 and laid off at its inner edge with the words triangle, miter, polygon, hexagon, heptagon, etc, as shown.
The stock 1 is provided in coincidence with the segment 2, with an opening 5, from the opposite sides of which V shaped tongues 6 project inwardly as shown, said tongues being in longitudinal alinement and serving as pointers for the graduations on the segment 4. In order to secure the stock in different adjusted positions with respect to the triangle 2, the said tongue is formed with another opening 7 between the opening and the pivot point 1*, and in this opening 7 is located a clamping screw 8 designed to work through the solid portion of the stock which separates the two openings 5 and 7, and impinging against the inner edge of the segment 4 so as to secure the stock and triangle together.
Preferably, the stock carries a spirit level 9 which is detachably secured thereto by means of screws or the like in the opening 7.
At the vertices of the angles between the stock or handle 1 and the graduated blade 3 when the stock assumes a true perpendicular position with respect to the said blade, I preferably form semicircular recesses 10 in the side edges of the stock, so as to enable the operator when squaring across his work, to mark with a pencil true up to the face line of the'stock. The sides of the triangle or frame 2 are also provided with small notches or recesses 11 at the ends of the segment 4.
From the foregoing description in connection with the accompanying drawings, it will be seen that I have provided an improved combination square of the character above set forth, which is simple in construction and which is adapted for all the diversified uses to which a device of this type may he put.
Having thus described the invention, what is claimed as new is:
1. As a new article of manufacture, a right angle triangle frame having its hypotenuse side provided with gradnations, a 90 degree segment secured within the frame, a stock pivotally connected to the frame at the vertex of the right angle thereof, and means for holding said stock at different angles with respect to the frame, the stock being provided in its side edges and at the points where said side edges intersect the hypotenuse side of the frame when the stock and said side are at right angles with respect to each other, with notches for the purpose specified, and the sides of the frame being also provided at the ends of the segment with similar notches.
2. A device of the character described, comprising a right angle triangle frame provided with linear graduations, a ninety degree segment mounted within the frame, a stock pivotally connected at one end to said frame at the vertex of the right angle thereof, said stock being provided with an opening 5 registering with the segment and with a distinct opening 7 between the opening 5 and the pivot point, and a clamping screw working through the stock from the opening 7 and adapted to impinge against the inner side of the segment whereby to clamp the stock in different positions with respect to the frame.
In testimony whereof I athx my signature in presence of two witnesses.
