OF CEDAR RAPIDS, IOVA.
FOLDING `SQUARE AND SCALE-HOLDER.
SPECIFICATION formingpart of Letters Patent No. 285,405, dated September 1883.Y
Application filed April 12, 1883. (Model.)
To aZZ whom it may concern: l
Beitknownthat,VILLIAMHGoLDsBERRY, of Cedar Rapids, in the county of Linn and State of Iowa, have invented an Improved Folding Square, of which the following is a specification.
My invention consists in forming and com- Y bining a hinge-j oint, a protractor, and an automatic locking device with the two arms of a square, as hereinafter4 fully set forth, in such a manner that the two arms can be readily folded into parallel position and automatically locked to promote convenience and safety in packing it away when not in use, and readily unlocked and distended to various angles relative to each other, and automatically locked in various positions when used as a protractor and square for drafting garments or for any other purpose for which protractors and squares are adapted to be used.
Figure l of my drawings is a top view of my joint and locking device. Fig. 2 shows my square open as required for use as a square. Fig. 3 shows it folded ready to pack away. Together these gures clearly illustrate the construction and operation of my complete invention.
A and B represent the arms of the square. They are preferably made of wood when designed for tailors7 use.
C is the socket portion of my hinged joint, preferably made of cast metal. It has a square corner, d, at its outside edge, a cavity, c, adapted to receive the knuckle portion of the joint, and an extension, f, at its inner edge to support the bolt of my locking device.
g is a bolt that extends through perforations ject up through a cavity in a covering-plate.
l 2 3 4 represent a serrated edge, or notches formed in the curved portion of the knuckle, that comes in contact with the bolt gwhen the arm B is moved to or from the arm A.
k is a flat metal plate fitted on top of the end of the arm B to overlap the angular end of the metal casting C2. A corresponding plate is fitted on the under side, and both the plates are riveted fast upon the end of the arm B and the angular end of the part C2. A
m is a flat metal plate fitted to the end of the arm A and the metal casting C. A corresponding plate is fitted to the under sides of the same parts, and both the plates are riveted fast to the armAaud the socket portion of the joint.
n is an extension and protractor formed integral with the plate m in such a manner that its curved edge will be concentric with the pivot ,and center r of the complete joint that extends through a perforation in the knuckle part C2 and coinciding perforations in the plates WL it.
s is a slot in the plate m, through which the catch h extends from the bolt g. By marking a scale of degrees on the protractor-surface n the short arm B can be readily set at any degree of angle desired relative to the long arm A.
t t are spring-catches fixed on the top surf face ofthe square to clasp detachable measures orlscales such as are used by tailorsin drafting garments.
To open my square when folded and locked, I simply, by means of the projecting catch h of the bolt g, press the bolt away from the serrated or notched segment of the knuckle portion C2, and then distend the hinge and move the arm B to any angle desired relative to the arm A, and allow the spring i to force the bolt into one of the notches in the segment or curved IOO 2 l I @MAM ing bolt7 and the metal casting C2, having a knuckle adapted to iit in the corresponding cavity of the said part C, and also a serrated or notched segment, 1 2 3 4, substantially as shown and described7 for the purposes specified.
2. rlhe joint-section C, having an extension and bolt bearing7 f, the sliding bolt g, having a proj ection7 71v7 andthe hinged section C2, having a serrated or notched segment7 l 2 3 4, arranged and combined with the arms of aV 'folding square7 substantially as and for the purposes set forth.
3. The improved folding square and protraetor composed of the arms A and B, the metal jointsections C and G2, the locking device j" g 7L i, the overlapping plates is, and the plates m, having an extension7 n, anda protractor-scale7 and a slot, s, in one of the said plates m n, substantially as shown and described7 to operate in the manner set forth7 'for the purposes specified. f
