SQUARE.
Specification of Letters Patent.
Patented March 5, 1907.
Application filed October 19, 1905. Serial No. 283,496.
To all whom it may concern.-
Be it known that 1, WILLIAM A. SoI-IMALZ, a citizen of the United States, residing at Duryea, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Square, of which the following is a specification.
The invention relates to improvements in squares.
The object of the present invention is to Improve the construction of squares and to provide a simple and comparatively inex pensive one designed particularly for carpenters, stone-cutters, and other mechanics who are compelled to carry a kit of tools and to enable the legs of a square to be readily separated both for arranging the square compactly for carrying, to prevent the square from being bent or otherwise injured, and also to permit the length of one of its legs to be varied, so that it will not be necessary to carry two complete squares.
A further object of the invention is to provide a square of this character which when the legs are assembled or connected will be firm and solid and in which the joint will be efiectually prevented from spreading.
With these and other objects in view invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claim may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawing, Figure 1 is a plan view of a square constructed in accordance with this invention. Fig. 2 is a transverse sectional view on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of one of the legs of thesquare, showing the beveled tongue. Fig. 4 is a detail perspective view of a portion of the other leg of the square, illustrating the construction of the spaced arms.
Like numerals of reference designate corresponding parts in all the figures of the drawing.
1 and 2 designate separable legs of a square, the legs being separable to enable the square to be compactly arranged to carry it in a box or chest and also to permit a longer leg to be substituted for the leg 2, so that it the end of the tongue at opposite sides thereof to provide a pair of crotches 8 to receive the outer ends 9 of the arms 6 and 7, which are exteriorly mitered or tapered to fit the crotches 8. The crotches, which receive the mitered or tapered terminals 9 of the arms 6 and 7, effectually prevent the latter from spreading when the parts are assembled and render the square firm and solid.
The arms 6 and 7 are provided at their inner faces with grooves 10, which are substantially V-shaped in cross-section and which receive the oppositely-beveled side edges 4 of the tongue 3. The leg 1 is also provided between tne arms 6 and 7 with a groove 11, also substantially V-shaped in cross-section, to receive the oppositely-beveled end 5 of the tongue 3. hen the tongue 3 is fitted in the grooves of the spaced arms and the leg 1, the upper and lower races of the legs of the square are flush and a solid structure is afiorded. The legs are securely connected together and maintained in their interlocked relation by means of a screw 12 which engages a threaded opening formed by matching recesses 13 and 14 of the tongue 3 and the arm 6 when the parts are fitted together. The recesses 13 and 14 are provided with threads, and when the parts are assembled they form a circular opening to receive the screw. The leg 1 is also provided with a threaded opening 15, adapted to receive the screw when the legs are separated; but the opening 15 may be provided in either leg of the square, as will be readily understood.
It will be seen that the means connecting the legs or members of the square provide a simple, strong, and rigid structure and that the legs may be readily separated to permit the square to be compactly arranged within a tool box or chest to prevent the'square from projecting therefrom and being bent or otherwise injured while being carried from one place to another. Also it will be clear that by connecting the legs of the square a longer leg may be substituted for for separably the leg 2 and that this variation in the length of one of the legs of the square may be secured without carrying two complete squares.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A square comprising a leg provided at one side with a groove and having spaced arms arranged at right angles to it and located at the ends of the said groove, said arms being also provided at their inner opposite faces with grooves and having their outer ends tapered, the end edges being straight and converging toward the outer extremities of the arms, a second leg provided with a tongue having projecting side and end edges to fit in the said grooves, whereby the two legs are slidably interlocked, the leg having the tongue being also provided at the inner end thereof with substantially triangular notches receiving the tapered ends of the said arms to hold the same against lateral movement, and the said tongue and one of the arms having matching threaded segmental recesses forming a circular opening, and a screw entirely filling the said opening and retaining the legs in their interlocked relation.
In testimony that I claim the foregoing as my own I have hereto afliXed my signature in the presence of two witnesses.
WILLIAM A. SCHMALZ.
