UNITED STATES PATENT OFFICE.
FREDERICK G. OSBORN, OF NEYVARK, NEIV JERSEY, ASSIGNOR TO EBER- HARD FABER, OF NEIV YORK, N. Y.
RU LER.
SPECIFICATIONforming part of Letters Patent No. 426,138, dated April 22, 1890.
Application filed October 19, 1889. Serial No. 327,526. (No model.)
To all whom, it may concern.-
Be it known that I, FREDERICK G. OSBORN, a citizen of the United States, residing at Newark, in the county of Essex and State of 5 New Jersey, have invented an Improvement in Rulers, of which the following is a specification.
Strips of india-rubber have been applied to rulers; but they are difficult to fasten in place and liable to become separated, and do not always take a proper bearing upon the paper.
My invention relates to a ruler having holes in the same, and blocks or plugs of rubber I inserted into such holes and projecting sufficiently to rest upon the paper and prevent the ruler slipping. These blocks are easily and strongly connected to the ruler, and are reliable in aiding in keeping the ruler in place while being used, because each rests firmly in place upon the paper while the ruler is being used.
In the drawings, Figure 1 is a view of the under side of the ruler, and Fig. 2 is a section at the line as m.
The ruler a is to be of any desired size and shape. Usually it will be flat and sectionally of a shape similar to that represented. In this ruler holes are bored at suitable distances for the reception of the rubber blocks or plugs b, which plugs project at their ends from the surface of the ruler, so as to rest upon the paper and prevent slipping.
If the plugs of rubber are only to project at one surface of the ruler, the holes may be bored only partially through. Otherwise said holes may be bored entirely through and the ends of the plugs project beyond both surfaces of the ruler.
I claim as my inventionl. The combination, with the ruler, of plugs of rubber inserted in circular holes in the ruler, substantially as set forth.
2. The combination, with the ruler, of plugs of rubber inserted in holes in the ruler and projecting at both top and bottom surfaces of the ruler, substantially as set forth.
Signed by me this 14th day of October, 1889.
FREDK. G. OSBORN.
