` No. 206,410. Patenlted July 30,1878'.
UNITED STATES PATENT FFICE.
HENRY ADLER, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN RULERS.
Specification forming part of Letters Patent N0. 206,410, dated July 30,1378; application iled January 22, 1878.
To all uhom it may concern:
Beit known that I, HENRY ADLER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useul Improvement in Combined Ruler and 'Paper-Tearer, and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
My invention relates to au improvement in combined ruler, paper-tearer, pencil-sharpener, and T-square 5 and consists in construetin g said article in the form ot' a hollow prism, and of sheet metal, and providing one of its corners with a rounded surface to prevent blotting when using ink in the operation of ruling, the opposite edge or corner being used as a papertearer. One of its sides is spaced off with iigures for the purpose of forming a measuringrule. The rule is made hollow, forming a re` ceptaele for pens and pencils, which is inclosed by an erasive stopple and pencil-sharpener corresponding in form to the interior ofthe rule. At the closed end is a lead-pencil sharpener, said ruler being susceptible of bein g changed to a T-square by a detachable T-head.
To enable others skilled in the art to make my invention, I will proceed to describe its construction.
ln the accompanying drawings, which form part of my specification, Figure l is a bottom view of my improvement. Fig. 2 is a side view, showing the measuring-rule. Fig. 3 is a transverse section at line y y of Fig. l. Fig. 4 is an end view, showing theThead an d lead-pencil sharpener. Fig. 5 is aview of the stopple.
The rule is formed of a strip of sheet metal and bent into the form of a hollowl prism, the edges of which are united by the soldering process. One of the corners-or edges, B, of the under side A is rounded, so as to prevent blotting while using ink for ruling, while the opposite edge, c, is sharp and lies close to the paper, so as to form a paper-tearer. The face j is spaced off and marked with gures, so that it can be used as a measuring device.
The rule is made hollow for the purpose of forming a receptacle for pens and pencils, and is provided with a stopple corresponding in shape to the rule. One end of said stopple is provided with a rubber. The surface of the stopple is rough, so that it can be used as a slate-pencil sharpener. The opposite end ot the ruler is provided with a lead-pencil sharpener of the ordinary construction.
By eonstructin g an article of sheet metal, as hereinbefore describefhit can be used for all the purposes hereinbefore mentioned.
The advantage of said rule as a desk tool will be apparent to persons requiring to use such articles.
Having thus described my improvement, what I claim is- A rule made in the form of a. prism havin g a rounded and a sharp edge, the sides bein g spaced off and marked with gures and pro vided with a detachable T, whereby a ruler, measurer, papertearer, and receptacle for pens and pencils are formed, substantially as herein described.
II. ADLER.
