PATENT ABRAM E.- SELTZER, OF LEBANON, PENNSYLVANIA.
" FOLDING SQUARE.
SPECIFICATION forming part of Letters Patent No. 342,849, dated June 1, 1886.
Application filed January 2.7, 1886. Serial No. 199,597. (No model.)
To all whom it may concern:
Be it known that I, ABRAM E. SELTZER, a citizen ofthe United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Folding Squares; and I do hereby 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 appertains to make and use the same.
rlhe invention relates to folding squares, and has for its object the construction of a convenient implement for the use of carpenters and other workmen, which can be readily converted into a right or left hand square or bevel, or extended to form a long rule,aud changed from one position to another with facility and dispatch.
The invention will be hereinafter described, and particularly pointed out in the claims.
In the accompanying drawings, which form a part of this specification, Figure l represents a side view; Fig. 2, a detail, and Fig. 3 a sectional View.
Reference being had to the drawings, A represents the long arm or blade of au ordinary carpenters graduated square, which is 4provided with a series of holes, a l) c d cf g h,
eight in number', formed in a circle around the Stud t'.
B is the short arm or blade, also graduated, provided with a central aperture, k, which tits over the stud i, and a hole, Z, which registers with the holes formed around the Stud in the other arm or blade.
Upon the blade B is secured a spring, m, which carries a pin, a,which projects through the hole Z into the registering holes in the blade A, and automatically locks the blades when the hole Z is brought in line with either of the holes in the said blade.
The studi is provided with a screw-threaded projection, p, upon which is screwed a thumb-nut, q, for securing the two blades in any desired predetermined position.
By referrring to Fig. l it will be observed that when the hole Z in the blade B registers with the hole a in the blade A a right-hand square is formed. i
To change the position of the blade B the nut q is Slacliened, the spring m raised, and the pin a withdrawn from the hole a, when said blade may be pushed into either position shown in dotted lines, in which C represents an angle offorty-tive degrees up; D, the same angle down on the right side; E and F, corresponding reverse posit-ions; G, a left-hand Square; H, an extension ofthe arm or blade A, which forms a convenient rule for measuring purposes in many instances in which the ordinary two-foot rule is too short, and two rulesA must be joined or a rod used to span a space desired to be measured, or it will form a straight-edge for ruling purposes. I shows the blade B folded upon the blade A, for the purpose of conveniently carrying it in the hand, a tool-box, or an ordinary carpenters chest. Vhen set in either position, the nut q is tightened, and the parts A Btirmly held together.
Heretofore bevels and draftsmens squares have been made adjustable by providing a series of holes in one of the parts and a corresponding number of pins to register with each of the holes in the opposite part. By this construction it is necessary to separate the parts by lifting the blade from its stock and the pins out ofthe holes, and then change the angle and again insert all ofthe pins and secure the two parts by means of a screw.
An ordinary hinged measuring-rule has had a series of holes formed in the joint and a pin provided to lock them. In this construction the angle can be formed on one side only.
By my invention the short blade of the square rests upon the long blade, and can be adjusted to either side to form a right or left hand instrument, and the blades firmly secured against displacement.
Having thus fully described my invention, what I claim is- 1. A reversible folding square consisting of two overlapping blades, one of which is provided with a projecting stud and a series of holes arranged in a circle around said stud, and the other blade provided with an aperture corresponding with the stud and a hole arranged to register with eitherof the holes in the first blade, in combination with a spring locking device, substantially as described.
2. A reversible folding square consisting oi' ing the blades in anylocked position, substanro two overlapping blades, one of which is protially as described. vided with a projecting stud and a series of In testimony whereof I affix my signature in holes arranged in a circle around said stud, presence of two Witnesses. and the other blade rovided with an a )ern ture corresponding wpith the stud and 'a lliole ABRAM Ef OELTZLR arranged to register with either ofthe holes in the iirst blade, in combination with a Spring locking device and a clamping-nut for secur- Vitnesses:
