JACOB GUTH, OF SALEM, ILLINOIS.
RULE, SQUARE, AND NIITER.
SPECIFICATION forming part of Letters Patent No. 778,659, dated December 27, 1904.
Application filed July l, 1904. Serial No. 215,018.
T0 all whom '/t 71mg/ concern:
Be it known that I, J AooB GUTH, a citizen of the United States, residing at Salem, county of Marion, lState of Illinois, have invented certain new and useful Improvements in a Oombined Square and Miter; and I do declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it belongs to make and use the same, reference being' had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
The invention relates to a mechanics rule, and particularly to a structure combining in a single device a rule, square, and miter.
The invention has for an object to provide a construction of rule comprising three sections of equal length pivotally connected together, so as to fold one upon another and ce capable of opening into an extended position by a simple movement of the hand, while when adjusted relative to each other various angles may be secured and other functions herein.- after set forth rendered possible.
A further object of the invention is to provide means in one of the free ends of the rule for retaining the opposite free end in order to hold the same in any of its adjusted positions.
A further object of the invention is to provide the free ends of the rule with markers,
so as to 'adapt them for use as a compass, gage,
or marker.
Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.
In the drawings, Figure l is a perspective of the rule in extended position; Fig. 2, a similar view of the rule folded; Fig. 3, an elevation thereof; Fig. 4, a perspective of the rule set at an angle of forty-five degrees to form a square or miter; and Fig. 5, a similar view showing' the adjustment of the rule for forming a gage, compass, or bevel.
Like letters of reference refer to like parts in the several figures of the drawings.
The letter A designates the central section of the rule, which has pivotally secured at its opposite ends sections A/ and A2, of equal length, all of which are continuously and suc-v cessively graduated as usual for measuring purposes. These sections may be of any desired length, but are preferably eight inchesy struction wherein the section A2 is fold ed uponthe section A and the section Al by its eX- tended hinge folds over and upon the section A2, as shown in Fig. 2. The hinge can thus be opened by a quick movementv of the hand grasping the section A'.
A further object of the use of the three sections is to permit the formation thereby of various triangular figures or outlines in which the several sections lie at different angles to each other for the purpose of forming a square, a miter, or any desired beveled angles in different classes of Work. For this purpose the section A2 is provided with an opening B therethrough, adapted to receive the free end of the section A', which may be secured in its adjusted position by any desired means-for instance, a pivoted cam-lever B', mounted upon the section A2 at one side of the aperture B, so as to bear against the section A and clamp the parts in adjusted position. Under some conditions it is desirable to lock these parts, and this may be accomplished by means of a projection or shoulder B2 at one side of the aperture B, adapted to cooperate with a recess B3, formed upon the free end of the section A of the rule, so that the parts may be interlocked by the pressure of the cam. The free ends of the sections A' and A2 are provided with a scratch-point or marker O, which is adapted for use when the device is applied as a compass, gage, or marker, and one of these points may form a fulcrum, so that the other rotating about said first point may by adjustment define circles of different diameter, Fig. 5.
As shown in Fig. 4, the sections of the rule IOO may be adjusted to form a square, miter, or l said sections being provided with an aperture level, and the adjustment thereof may be varied to secure different angles, as shown in Fig. 5. In this figure one of the points C may be used as a gage by contacting the section A2 of the rule with the side of the material in order to marl; a line thereon at a proper distance from its edge, while if it be desired to use the invention as a compass one of the points C may be held to the material as a fulcrum and the other point swung upon an arc, as indicated by dotted lines in that figure.
lt will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as delined by the appended claims.
Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is
l. A rule comprising three sections of equal length pivotally secured to each other and adapted to fold with one of the end sections intermediate of the central section and the opposite end.
2. A rule comprising` a central section provided with an extended hinge at one end, an end section secured to said hinge, and an opposite end section pivotally secured to the opposite end of the central section and adapted to fold in contact with one face of the central section and between it and the opposite end section.
3. A rule comprising' a plurality of sections pivotally secured together, one free end thereof being provided with an opening to receive the opposite free end of the rule.
4. A rule comprising a plurality of sections pivotally secured together, one free end thereof being provided with an opening' to receive the opposite free end of the rule, and means to clamp the free ends of said `rule in contact with each other.
5. A rule comprising three sections of equal length pivotally secured to each other, one of to receive the opposite free end of the rule.
6. A rule comprising three sections of equal length pivotall y secured to each other, one of said sections being provided with an aperture to receive the opposite free end of the rule, and a pressure device mounted adjacent to said aperture to contact with the free end passing therethrough.
7. A rule comprising three sections of equal length pivotally secured to each other, one of said sections being provided with an aperture to receive the opposite free end of the rule, a pressure device mounted adjacent to said aperture to contact with the free end passing therethrough, and an interlocking connection between said free end and a Wall of the aperture.
8. A rule comprising three sections of equal length pivotally secured to each other, one of said sections being provided with an aperture to receive the opposite free end of the rule, a pressure device mounted adjacent to said aperture to contact with the free end passing therethrough, an interlocking connection between said free end and a Wall of the aperture, and projecting markers carried by the free end of the rule.
9. A rule comprising a plurality of sections pivotally secured together, the free end of one section being ad justabl y extended through the free end of the opposite section, and laterallyprojecting points carried by each of the free ends.
10. A rule comprising three sections of equal length, one of the end sections thereof` being connected to the central section by an extend-
