POCKET RULE.

" JOSEPH MOLEAN, OF ROGKVILLE, CONNECTICUT POCKET==RULEQ SPECIFICATION forming part of Letters Patent No. 378,894, dated March 6, 1888.
Application filed March 16, 1887.
Serial No. 231,092. (No model.)
and State of Connecticut, have invented certain new and useful Improvements in Pocket- Rules, of which the following is a full, clear, and
' exact description, whereby any one skilled in the art can make and use the same.
The object of my improvement is to provide a pocket-rule with a bevel or angle measuring device that shall besimple and compact; and to this end my improvement consists in a rule having a joint with a tongue on one part roughened on the edge or provided with indentations or teeth, and the other part of thejoint bearing a tilting locking device and having the outer surface of one of the cheek-pieces graduated; and it further consists in details of the several parts and their combination, as more particularly hereinafter described, and pointed out in the claim.
Referring to the drawings, Figure I is a plan view of a part of a rule, showing the joint that embodies my improvement,with parts broken away to show construction. Fig. 2 is a plan view of apart of a rule, showing the sections closed, with the joint that embodies the improvement broken away to show construction. Fig. 3 is an end view of the rule with thejoint closed.
In the accompanying drawings, the letter a denotes a carpenters rule that may be of any material and construction; I), the joint that unites the several parts of the rule edgewise, or in the direction of their width, as commonly made. This joint is composed of one part having a tongue, b, that is fastened to one section of the rule by straps and rivets, and of the joint part 0, having a slot to receive the tenon between the cheek-pieces c. This joint part is preferably formed of sheet metal folded to shape to fit upon the end of a section of the rule and extending along it a sufficient distance to afford a hold for the rivets by means of which the part is attached to the rule-section. The two parts of the joint are united by means of a pin or pivot, d, so that when the sections are closed together edgewise the line of division between the rules passes through the center of the pivot, while the shoulders at are in line with each other and on a line passing th rough the center of the joint and at about right angles to the line of division of the rule-sections.
The projecting semicircular part c of the Y joint is graduated-that is, divided into degrees or parts of degrees-so that when the rule is open the angular divergence of the sections of the rule that are united by this joint may be measured by noting the position of the shoulder a on the graduated are marked on the projecting part c of the rule-joint.
In order to hold the rule-sections in a certain position after having measured the angle, a catch or stop is used. This consists of a tilting block, f, hung within the fold of the joint-section 0, near one edge, and with a hooked part, f, that is adapted to engage with the roughened or indented periphery, of the tenon b.
The catch is moved into and out of engagement with the tenon by means of a sliding bolt, 9, that is operated by means of the stud 9, that projects beyond the edge of the rule. The lower surface of this bolt is beveled and slides upon the beveled back of the tilting catch. By means of this bolt the'sections of the rule may be set at ninety degrees with each other, locked there, and the device used as a square, or the section may be set at any desired degree and locked in that position, or the arc may be used for measuring bevels or slopes, as desired.
Lclaim as my invention- In combination with the hinged sections of a rule, the joint I), composed of the tongue I), with a roughened edge, the pivot 02, and the socket c, the tilting block f, hinged within the fold of the joint-section and having the hooked endf, and the slidingboltg with rounded face fitting the recessed back of the tilting block and having the projecting stud 9, all substantially as described.'
JOSEPH MOLEAN.
