CHARLES H. WES'ICOTT, OF SENECA FALLS, NEW YORK.

RULER.

SPECIFICATION forming part of Letters Patent No. 370,668, dated September 27, 1887.

Application filed January 27, 1887.

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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a plan Viewr of my ruler, and Eig. 2 is a 'transverse section of the same.

My invention relates to metalmounted wooden rulers; and it consistsinthe construction and novel combination of parts, as here-- inafter described, and pointed outin the claim.

Referring by letter to the accompanying. drawings, A designates the body of the ruler, which is made of wood, and is provided with a beveled straight-edge, B, on which is delineated a scale which is divided into inches and fractions of inches. The straight-edge B is kerfed in its front edge throughout its ent-ire length, as at C, and in this kerf C is seated and 'secured a metal straight-edge, D, preferably of brass, although any other desirable metal may be used. The body A of the ruler is kerfed longitudinally in its upper face parallel with the integral projecting flange or rib E along its rear edge, and is provided with a second longitudinal kerf, F, in the rear edge of the body A, immediately beneath the flange or rib E. In these kerfs C and F are seated and secured the edges of the hollow metal or nearly tubular back G, which not only serves asa hand-piece by which to manipulate the Serial No. 225,668. (No model.)

ruler, but also serves as a straight-edge for guiding the pen in inking-in pencil-lines and in drawing ink-lines primarily. Y

'The hollow metal back may be used when the ruler is in either the normal or in the in` verted position. p

It will be seen that a ruler thus constructed is very simple, the parts can be readily put together, and the complete articles placed upon the market at a minimum expense. It vwill also be seen that should the tubular portion become injured in any manner it may be slipped out of the grooves and replaced by another Without impairiug the usefulness of the other parts.

I am aware that it is not new to form aruler from sheet metal having one of its edges formed into a cutting-edge and its opposite edge rolled.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

The combination, with the wooden body A, provided with the projecting flange or rib E along its rear edge, kerfed longitudinally in its upper face at H, and provided in its rear edge' with the longitudinal kerf E, parallelwith the kerf H, the hollow metal nearly tubular back G, having its edges seated in the' CHARLES H. wEsroorr.
