Application filed February 9, 1905. Serial No. 244,903.

To all whom it may concern.-

Be it known that I, GEORGE W. MACKEN- ZIE, a citizen of the United States, residing at Ben Avon, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Blotting- Rulers, of which the following is a specification, reference being had therein to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of my improved blotting-ruler. Fig. 2 is an end view thereof. Fig. 3 is an edge view of one end. Fig. 4 is a-similar view, partly in section, showing the securing-clip raised in the operation of attaching one end of the blotter. Fig. 5 is a detail view showing the under side of the securingclip. Fig. 6 is a similar view of one end of the strip of blotting-paper, indicating its turned-up end.

My invention relates to improvements in rules or straight edges such as are commonly used by bookkeepers, accountants, and others; and it consists of such a ruler provided with a facing of blotting-paper or other absorbent material so combined with the ruler as to be readily attachable to' and detachable therefrom, whereby the ruler may be used in the ordinary way, also to the means incorporated with the ruler for attaching the blotting element.

Referring to the drawings, wherein the invention is illustrated, 2 represents an ordinary ruler or straight-edge usually having a beveled edge at one side. At each end of the ruler are located clips 3, adapted to securely hold the turned-up ends of a strip 4 of blotting-paper in such a manner as to neatly secure it along the under side of the ruler, whereby it may be used as a blotter without in any way interfering with the ordinary use of the ruler. The strip 4 of blotting-paper is preferably cut out, as at 5, when necessary, so as to fit neatly around the ends of the ruler and to correspond with the beveled edge, thus providing attaching-terminals 6 of somewhat narrower width adapted to be bent up over the ends or the ruler, as clearly shown. The clip 3, as shown in the drawings, consists merely of a spring-blade of sheet metal secured upon the ruler by a screw 7 and provided with a downwardly-turned pointed tip or projection 8, adapted to pierce through the blotting-paper, a corresponding aperture 9 being cut out of the upper face of the ruler to provide for clearance. 10 of the clip preferably extends somewhat beyond each end of the ruler, whereby it may The end i be readily lifted by the finger for the purpose of inserting the ends of the blotting-strip, and when released the point 8 will pierce through the strip and also bear down upon it with considerable pressure, due to its resiliency. While this construction of clip is well adapted to the purpose and is very simple and convenient, it is obvious that other forms of securing devices may be employed for holding the ends of the blotting-strip, and I do not, therefore, desire to be limited to the 6X act construction shown.

The blotting-strips may be readily renewed from time to time or may be reversed, if desired. They may be provided in suitable shape and quantity and furnished with the ruler or may be readily cut from a sheet of blotting-paper. The device results in a great saving of time and avoids the necessity of using a separate blotter and is immediately available by accountants for the purpose of blotting lines drawn by the pen with the aid of the ruler in footing up accounts.

The advantages of the invention are manifest and will be appreciated by all those accustomed to the use of separate rulers and blotters. Various adaptations of the invention may be made, or it may be changed or varied in its details of construction by the skilled mechanic without departing from the following claims.

What I claim is" 1. A ruler provided at each end. with pivotally-mounted spring-clips having inwardlyturned piercingpoints, substantially as set forth.

2. A ruler provided at each end with clearance-recesses, and. pivotally-mounted springclips having inwardly-turned piercing-points adapted to enter said recesses, substantially as set forth.

3. A ruler provided at each end with clearancerecesses, pivoted spring-clips having inwardly-turned points adapted to enter said recesses, and a strip of blotting-paper extending longitudinally of the ruler along its under side with its terminals bent up and secured between the ruler and said clips at each end, substantially as set forth.

4. A ruler provided at each end with clear ance-recesses, and pivoted spring-clips having inwardly-turned piercing-points adapted to enter said recesses, said clips extending outwardly beyond the ends of the ruler, substantially as set forth.

5. A ruler provided at each end with clearance-recesses and having spring-clips pivotally secured to the ruler at their inner ends provided with inwardlyturned piercingpoints formed by pressing the metal downwardly in V form whereby the points are adapted to pierce through the terminal edges of a blotting-strip and into the clearance-recesses, substantially as set forth.

6. The combination with a ruler provided at each end with clearance-recesses and pivotally-mounted spring-clips having inwardlyturned piercing-points, of a strip of blottingpaper of uniform width bounded at each end by bias cuts terminating in narrowed extensions adapted to be bent upwardly around the ends and top of the ruler, and to be secured thereto, substantially as set forth.

In testimony whereof I afliX my signature in presence of two witnesses.

GEORGE w. MACKENZIE.
