UNI/Ten STATESv GEORGE D. UMLAND, OF OSCEOLA MILLS, IVISCONSIN.
COMBINED- RULEAND SQUARE.
SPECIFICATION formingl part of Letters Patent No. 303,077, dated August 5, 1884. Applieniion lod April, 1884. (No mollet) Ze it known that I, G-nonen D. UMLAND, n citizen of the United States, residing at Osceola Mills, in the county of Polk and State of l/Visconsin, have invented certe-in new und useful Improvements in Combined Rules and Squares, of which the following is a. description.
Figurel is e view of a one-foot rule folded at the middle joint. Fig. 2 is en edge view of Fig. 1, with the righthund portion folded over the left-hand portion, completely closing the rule. Figs. 3 and 4 are views of the rule from opposite sides when disposed for use asn try-square.
My invention is designed to provide a combined rule and squareV which, while fulfilling all lthe functions of a. folding pocket-rule, shall also serve es a try-square; and it consists in attaching to or forming on the extreme end of the outer section of the jointed rule a metallic abutment-block, which, when seid outer section is folded in Ward, laps over the k nueklejoint et the middle of the rule, und forms a stop, against which the other section of the rule shuts when it is exactly at right angles ornt ninety degrees to the other niain section.
In the drawings, A A A2 lA3 represent the four sections of an ordinary one-foot (or twofoot) pocketrule- VOn the extremity of one of the outer sections, A or A3', is formed or ettnehed zt solid and permanent metal block, a, which is just equal in width to the Width ofthe rule'sections, and in thickness is equal to the thickness ofthe two rule-sections laid together. Ordinarily the outer end of the outer rulesection, when folded in toward the j oint, termiinwardly upon A. the extreme end of this i block a is in :t line with the outer edge of the other rule-sections,A'- A, and the sections AL l A3, when disposed at right angles to A and v A', the inner end of A2 abut-s against the block (t, and denes the position ofthe two sides of the angle of ninety degrees. In order to allowv the block c to fit around the rounded por tion of the knuckle-joint, said block has :i recess, b, at its corner.
By ineensot' my invention es thus described, the folding pocket-rule is just :is convenient and useful usbefore, and yet it is made also to serve as e. reliable try-square in the absence of other tools, thus giving un extended range of use to the'rulend inakingaportable pocket-tool` l Hoving thus described my invention, what I claim es new is l. A pocket-rule having hinged sections, with nu integral block on the end of its outer section of greater thickness than the rule-sec tion, and adapted to forni un abutment for the other hinged section, to define au angle of ninety degrees and forni a try-square, its described.
2. The pocket-rule having integral block a,
p with curved recess b at `one end, us described.
