IMPROVEMENT IN ADJUSTABLE MEASURING-RULE.

m. WHOM IT MAY oononnn:
,Be it known that I, ISAAC WILLIAMS, of Westficld, in the county of Hamilton, and State of Indiana, have invented a new and useful Improvement in Adjustable Measuring-Rule; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of thisspecification.
This invention relates to a rule which may be varied from a square or right angle, either way, to an obtuse or acute angle, with extension ends or slides in the body, as well as in the tongue of the rnlejand the invention consists in the manner in which the rule is adjusted and extended, so as to enable the operatoror workman to measure angles and distances, as I will proceed to describe. I
' Figure 1 represents a longitudinal view of the instrument, showing the manner of its construction and operation. i I
Figure 2 is an edge view of the same.
Similar letters of reference indicate corresponding parts.
A is the staff or body of the rule. I i
B is the tongue.
These two partsare connected together by a screw with a thumb-nut, as seen at the angle 0, where they form a joint. I
The friction between the two is increased or diminished by turning the thumb-nut.
Each part has an extension-end. p I i v D is the part which is attached to A, and, as represented in the drawing, it is drawn out or extended.
This part D is slotted, as seen ate.
F is a screw, with a thumb-nut, by which it is held in place. 7
G is the extension-end of the tongue, shown in dotted linesin the drawing.
This is also slotted, and is held in place by a screw and thumb-nutflt.
J is a brace,,formed witha slot-end, as seenat z. i V
The opposite end is attached by a pivot to the tongue B, upon which pivot the brace tu-rns.
As the angle of A and B is varied, the slotted end of' the brace slides up or down on the part A,and is confined in any desired position by a screw and thumb-nut, k. I
The particular use for which this instrument is intended is for fitting sashes and doors into their respective frames, without compelling the joiner to font and try," as he usually does, as, by this invention, the exact angle, as well as the exact length and width, may be ascertained, and the door or sash marked and fitted accordingly.
The length and the width are ascertained by extending the ends D and G, and the angle is determined by varying the tongucB, as before stated.
Itwill be apparent that this instrument may be used for various other purposes than those named, as for measuring distances between fixed points, and" for marking angles or bevels of various kinds, as any amount of variation may be given the tongue B by lengthening the sloti. v I
The body of the rule A, as well as the tongue B, is graduated or marked ofi into inches-for...the measurement of distances. i
Having thus described my invention, I claim as new, and des re to secure by Letters Patent---- 7 The combination of the pivoted adjustable brace J, slotted at i, with the graduated part B, and its slotted eigten'sion G, and with the graduated partA, and its slotted extension D, all constructed as described,-for the purpose specified.
