PATENT OFFICE.-

CHARLES E. APPLER, OF CHICAGO, ILLINOIS.

MAGNIFYING IMPLEMENT.

Application filed May 4, 1917.

T all whom it may concern! Be it known that I, CHARLES E. Arrmm, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Magnifying Implements, of which the following is a full, clear, and exact specification.

This invention relates to improvements in magnifying implements, and is especially designed and intended for the convenience and to save time for the user of a pen or pencil in finding the name, station and number in telephone directories, especially those in large cities, wherein they are in fine print and close together, and for such other purposes as the magnifying glass thereof is adapted.

The object of my invention is to successfully utilize the stem of a penholder and the eraser extension of a pencil as a means for holding and providing a handle for a magnifying glass of a form not interfering with or obstructing the use of either a pen or a pencil, and which at the same time is of the length of a line containing in a telephone directory the name, residence address, and telephone designation, as now commonl contained in the telephone directories 0 large cities, and a magnifying glass of a length and width adapting it for other purposes.

With these ends in view, my invention finds embodiment in certain features of novelty in the construction, combination and arrangement of parts by which the said objects and certain other objects are attained, all as hereinafter fully described with reference to the accompanying drawings, and more particularly pointed out in the claim.

In said drawing:

Fig. 1 illustrates in front elevation a pen holder in which my invention finds its embodiment.

Fig. 2 is a detail and somewhat enlarged side elevation thereof.

Fig. 3 is a detail side elevation showing the adaptation of my invention in connection with the eraser extension of a leadpencil.

Fig, 4: is a front elevation of the same.

Fig. 5 is a transverse section taken on the line 55 of Fig. 1, and- Fig. 6 is a transverse section taken on the line 6'-6 of Fig. 3.

Serial No. 166,339.

Similar characters of reference indicate the same parts in the several figures of the drawin s.

In Figs. 1 and 2, 7 indicates a holder for a pen 8, which holder may be provided at its upper end with a socket for receiving a magnifying glass 9, but is preferably hollow, and may be a fountain-pen holder in which to project and thereby secure the magnif ing glass 9.

or forming a tight joint between the magnifying glass 9 of the holder 7, the magnifying glass, see dotted lines, Fig. 1, is provided with a shank 10 conforming in cross section to the internal walls of the adjacent end of the holder, and may be provided with a shoulder 11 forming a stop limiting the inward thrust of the magnifying portion of the glass.

Magnifying glass 9 is provided with four. surfaces, two of which 1212 are parallel, and the other two 13-13 are convex, which latter converge from the shank towards the outer end 14 of th glass, which said several surfaces are of a length corresponding with the length of a line in a telephone directory, and preferably of a length corresponding with the line in a city directory, the surfaces 13-13 constituting the magnifying portion of the glass, so that when held over such line using the penholder as a bandle therefor, the letters and figures may be clearly, quickly and conveniently identified when otherwise it would be difficult owing to the fineness of their print, or the closeness of adjacent lines, each of which constitutes a directory for as many differing persons.

My invention also finds its embodiment, see Figs. 3 and 4, in the extension 15 for a lead-pencil 16, which extension, as usual, provides a socket receiving the end portion of the encil, and has at its free end an eraser 1%.

For the purposes of my invention the opposite sides of the tubular extension 15 between the inner ends of the socket and the eraser are cut away, so to speak, see Fig. 6, as indicated at 18-18 through which to expose a double convex lens 19 embraced by the side walls 20 of the extension, and held from lateral detachment therefrom by the projection of the ends 21-21 in the opposing tubular portions of the holder as indicated by dotted lines in Fig. 4, the side walls 20 serving also as a guard against fracturing the lens from the impact of a blow.

The opposing convex surfaces 2222 of the lens 19 preferably project outwardly from the sides of the holder, the length of the lens 19, as described with reference to Figs, 1 and 2, being suflicient to take in and magnify in its entirety the line in a directory, the pencil and the extension thereof providing a convenient handle for holding the lens in its operative position over such line.

I have illustrated my invention in connection with the extension eraser of a lead pencil, for the reason that they are largely and quite commonly used for the purpose of economy in the use of lead-pencils, sold separately therefrom, and are adapted to outlast several pencils not only before, but after, their rubber erasers are from use worn out, and that such extensions, made as they are from metal in tubular form, are

best adapted to protect the lens against breakage, and at the same time furnish a means for locating the lens in the most con venient position for use.

For the purposes and uses of In invention, it is found in practice that the ens may be of pressed glass, and need not be made from ground glass, which is comparatively much more expensive, and as a result of which the use of a magnifying lens in connection with both a penholder and a pencil extension is provided for at a comparatively small additional expense.

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

As a new article of manufacture, a tubular holder about the diameter of a pencil and having an extension at one end serving as a handle, said tubular holder having windows therein on opposite sides and a long narrow lens arranged longitudinally within said tubular holder with its magnifying surfaces exposed at said Windows, the maximum thickness of said lens being no greater than the diameter of the tubular holder which supports and protects it.

In Witness whereof, I have hereunto set my hand and aflixed my seal, this 2nd day of May, A. D. 1917.
