CHARLES o. LoETz, or OMAHA, NEBRASKA, AssIGNoE 0E ONE-HALE 'ro WILLIAM E.
LONG, 0E OMAHA, NEBRASKA.
SQUARE.
To all whom t may concern Be it known that I, CHARLES C. LoRTz, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented new and useful. Improvements in Squares, of which the following is a specification.
This invention relates to squares and more particularly to carpenters steel squares, the object of the invention being to provide a steel square having the blades foldable upon one another so that they will occupy small spa-ce in the tool chest and may be transported from place to place conveniently.
A further object of the invention is to so construct the hinged parts of the square ltghat the strain is removed from the pivotal olt.
Further objects of the invention will appear as the following specific description is read in connection with the accompanying dra-wing, which forms a part of this application, and in which- Figure 1 is a fragmentary elevation showing the square in open position. Fig. 2 is a similar view with the square in closed position. Fig. 3 is an inside elevation of the tongue. Fig. 4c 1s .a similar view of the blade.
Referring' more particularly to the drawing, 1 represents the blade of the square and 2 the opposite blade or tongue. The blade 1 is provided with a right angularly eX- tending hinge member 3 which is circular, as at 1, on its outer edge. Formed on the right angular extension 3 .are ribs 5 and 6 and between the ribs 5 and 6 an annular groove 7 and within the rib 6 a circular socket 8. Outside of the rib 5 the extension is reduced to form a circular track 9 for the rib 10 upon the tongue 2. rlhis rib 10 oorresponds with a similar rib 11 separa-ted therefrom by a groove 12 and inside of the rib 11, and separated therefrom by a groove 13, is a central stud 14 adapted to engage the socket 8. The stud 111 is centrally apertured and screw threaded to receive a pivoting screw 15 which passes through a countersunk hole 16 arranged in the extension 3 coincident with the socket 8.
Extending through the extension 3 and Speccaton of Letters Patent.
Application filed June 6, 1911.
Patented July 29, 1913.
Serial No. 631,506.
the end of the tongue 2 are suitable apertures 17 and 18, arranged at quartering intervals through the rib 5 and within the groove 12 respectively. Vithin the apertures 18 of the stud 5 are permanently positioned and secured therein steel pegs or pins 19, said pins may be suitably secured in any well known manner, suoli as solder or the like. rIhese pins are adapted to register with the apertures 17 when the square is adjusted to either open or folded position. This function is accomplished by the loosening of the pivoting screw 15 and by a slight lateral adjustment. The projecting portion of the steel pegs or pins 19 may be readily withdrawn and inserted in the respective apertures 17 of the other blade member 2. by accomplishing this, a positive locking action is obtained between the parts 1 and 2 in either position.
Having thus described the invention, what I claim as new is A square comprising a pair of blades, one of said blades being provided with a right angular hinge extension having a circular outer edge; a bolt for pivoting the other blade to the hinge extension, a pair of relatively spaced circular' ribs formed on the extension, one of said ribs being provided with a series of apertures, and the said ribs having therebetween an annular groove, a circular track disposed outside and concentric with the rib having the apertures, the other blade being formed with a. series of annular ribs and grooves adapted for interlocking engagement with the ribs and grooves of said angular extension, the said other blade having a series of apertures disposed in one of its grooves and arranged at quartering intervals and pins permanently seated in the apertures of the ribs and adapted to enter the apertures in the grooves of the other of said blades, whereby a positive locking action is obtained between the blades in either open or closed position.
In testimony whereof I ailix my signature in presence of two witnesses.
