MILTON \V. LEXAXDER, OF .\'E\\' YORK, X.

ANTIBLOTTING-RULER.

Specification of Letters Patent.

Patented Aug. 4, 1908.

Application filed December 12, 1906. Serial No. 347,499.

T all; uliom it may concern:

Be it known that I, MiLrox \V. ALEXAX- DER, a. citizen of the United States, residing f at New York, county of New York, and

s v l btate of .\cw lork, have invented certain new and useful Im rovements in Antiblotting-Rulers, of whic i the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter (lo-- scribed and subsequently claimed.

Reference may be had to the accoiiipanying drawings, and the reference characters I marked thereon, which form a part of this specification. Similar characters refer to snnnar parts in the several figures therein.

Figure 1 of the drawings is a view in perspective of the improved ruler, bottom side up, and showing a single sheet of blotting material. Fig. 2 is a cross section taken 01;

the broken line x.v in Fig. 1 showing the blotting material in three sheets instead of one sheet. Fig. 3 is a perspective view similar to that shown in Fig. 1 with the blottiig material detached. Fig. 4 is a view in perspective of one of the end-clips detached.

My invention relates to improvements in a combined ruler and blotter.

The invention consists in providing the under surface of a ruler-body with a rabbetgroove adapted to receive one or more sheets of absorbent material, and securing theabsorbent material in such groove by means of detachable wire clips inserted in the ends of the ruler-body, and lapping the ends of the absorbent material whereby the form and tll].'-.(ll$l()ll$ of the ruler, when provided with the absorbent material, do not differ.

from the form and dimensions of rulers of the same general character which are not provided with absorbent blotteis.

The object of the invention is to provide i an ordinary ruler with an absorbent material which can be easily and quickly changed without interfering with any of the functional uses of the ruler as will be hereinafter more fully described and pointed out in the claims.-

I have shown an ordinary ruler having one edge beveled and the opposite edge provided with a projecting ruling surface in combination with three sheets of blotting paper.

. 1, represents the body of the I'll er, and. 2,

a bras strip extending along the beveled l 1 i edge to form a ruling surface extending lonedge in the common well-known manner.

lThe body of the ruler is provided on its under surface with a rabbet or groove, 3, extending its entire length. The groove is l of the proper depth to receive the desired,

thickness of blotting material.

The drawings represent the nibbct of the proper depth to receive three sheets, 4, of ordinary )lotting paper, as seen in Fig. 2, l which just fill the rabbet so as to be flush with the unrabbeted portion, 5, of the ruler body, a single sheet of blotting material thick enough to fill the rabbet being shown in Fig. l. The sheets of blotting paper are de- I tachably secured in the rabbet by means of end clips 66. These clips are preferably made of wire bent in the form shown in Fig. 4, the shanks, 7, of the cli being inserted in apertures in the ends of the ruler-body, and the heads, 8, being adapted to bear upon the outersurface of the outer sheet of blottin paper, as shown in the drawings, and hold the sheets firmly in place. The ends of the ruler body are preferably slotted from the cli aperture to the rabbct in order that the yoltes, 9, of the clips may enter such slots the ruler-bod v.' ily become embedded in the yielding lott-ing sheet so that neither the clips nor the blotter sheets will form projections beyond the usual dimensions of the ruler, giving the ruler provided with the blotting sheets the same form and dimensions as ordinary rulers of the same class whichare not providedwith antiblott-eis. i If a single sheet of blotting paper is emploved, i it can be easily turned so as to present a clean I surface, after one surface has become satu rated with ink, it only-being neces ary to remove the clips, turn the blotter-sheet, and reinsert the clips; and when two or more sheets are employed after the outer sheet has been used and both sides saturated, it can be placed next to the ruler-body thus presenting E a fresh sheet upon the outer surface for use am the sheets turned and interchanged until all have been saturated. Such a combination of blotting sheets with a ruler-body and. means for securing the sheets in position preisents a neat and useful antiblotting ruler l which will not interfere with its uses as a ruler for any purposes for which a ruler is adapted.

It will be observed that the upper portion of the ruling edge, 10, overhangs or projects beyond the lower portion, 12, of the same i and not project beyond the end surfaces ofl The heads of the clips readitudinally 01' the ruler-body. The strips of I blotting paper are preferably of a width to complete y fill the rabbet-groove and extend to, or a little beyond, the edge, 12, so that 5 when a penis used in connection with the ruling surface of the edge, 10, the ink cannot by any possibility through contact with the subtending edge, 12, de )osit a blot of ink upon the paper being ruled, an Y ink which might be de )osite d upon the lower edge, 12, being absor ed by the sheet of blotting paper. lVhile one of the longitudinal edges of the ruler has been shown beveled, it is obvious that this edge may be of any known form or material.

\Vhat I claim as new and desire to secure by Letters Patent is:

1. The combination with a ruler-body having a rabbet-groove on its lower surface; of absorbent material filling such groove, and detaehably secured therein whereby the lower surface of the absorbent material is in the same plane with the lower surface of the ruler-body adjacent to such rabbet-groove. 5 2. The combination with a ruler-body having on one of its longitudinal edges an overhanging ruling surface, and a rabbetgroove on its lower surface extending longitudinally throughout the length of the ru er and transveisely from the edge s'ubtending the ruling surface )artway only to the 0 150- site edge of the ruler-body; of an absorbent material filling the rabbet-groove and means I for detachably securing the absorbent material within such groove.

3. The combination with a ruler-body having a rabbet-groove on its lower surface extending from end to end of the ruler-body of one or more sheets 01'- absorbent materia adapted to fill such rabbet-groove; and end- 40 cli )s severally provided with shanks detachably inserted in the ends of the ruler-body and heads for lapping the ends of the absorbent material.

4. The combination with a ruler-body provided on its under-surface with a rabbetgroove extending from end to end of the ruler-body, each end of the ruler-body being provided with a clip-aperture, and a slot eX-. tending from the clip-aperture to the rabbet- 5o groove; of one or more sheets of absorbent material adapted to fill such rabbet-groove; and end-clips severally comprising shanks and yokes adapted to be detachably inserted in the clip-apertures and slots respectivcly in the ends of the ruler-body and heads ada )ted to respectively lap the ends of the blotting material.

In testimony whereof, I have hereunto set my hand this 28th day of November, 1906.

MILTON \V. ALEXANDER.
