Oct. 13, 1931. A. e. BRADFORD MAGNIFYING GLASS ATTACHMENT FOR DIAL TELEPHONES Filed May 28, 1930 Patented Oct. 13, 1931 UNITED; STATES PA -Eur OFFICE AIDA G. B RA DFQRD, OF SAN FRANCISCO, CALIFOBNIA- MAGNTFYIN GLASS ATTACHMENT FOR DIAL TEIJEPHONEB Application and Kay 28, 19st. Serial No. 458,682.
This invention relates to magnifying glass attachments for dial telephones, and the primary object thereof, is to rovide an at- I tachment of this character, w ich can be'eas- I ilyand quickly applied to and removed from the telephone without the manipulation of any art or parts of the holding means, there y to enable the lass to be rendered available for use in rea in or locating telephone numbers in the telep one directory. This application is a continuation in part of my Patent #1,762 809, June 10, 1930.
A further object of the invention is to provide an attachment of this type wherein the magnifying glass is frictionally supported and held also against turnin or axial movement, and wherein same can e removed and applied by a mere bodily movement of the lass.
g Still further the invention aims to provide a sim 1e and economical holder and one wherein the handle of the glass is but slightly modified so as to not detract from its usual appearance.
The invention has still further and other objects which will be later set forth in the course of the following description:
In the drawings:
Fig. 1 is a perspective view of the invention showing same applied to a telephone, the latter being illustrated in dotted lines;
Fig. 2 is a top plan view of the invention;
Fig. 3 is a section on line 3-3 of Fig. 2;
Fig. 4 is a fra mentary top plan view of a modified form 0% the invention, and;
Fig. 5 is a section on line 55 of Fig. 4.
In proceeding in accordance with the present invention a bracket is provided which is composed of a strip of metal having one end bent to form a spring jaw 1, thelatter shaped to engage about the telephone post or column T. The opposite end of the metal strip is bent to provide a substantially J-shaped jaw 2, the latter being adapted to grip a flash light L.
Referring to Fig. 1 of the drawings it will be noted that the flash light is held closely adjacent to the telephone column and at a distance above the dial D, the flash light having the usual lamp E at its bottom and a cover 0, the cover when open completing. the circuit through the lamp E and also acting as a reflector to direct the rays from the lamp onto the dial. A substantially L-sha'ped clip 3 is welded or otherwise secured to the .55 outer side of the J-shaped jaw 2 and is perforated to receive a bolt 4 having a wing nut 5 thereon, the bolt 4 extending through one end of a substantially L-shaped magnifymg glass support 6, the opposite end of 0 which support or holder has a slot 11 extending through its upper edge. The frame of a magnifying glass 7 is provided with a handle 8 which latter is formed with a pair of opposed parallel slots 9, which slots re- .ceive the side edges or walls 10 resultant from the formation of the slot 11, in the holder 6, whereby it will be seen that the magnifying glass is not only held firmly in position'and against turning or axial movement, but also may be easily and quickly removed from and applied to the holder as desired.
By virtue of the adjustable clamping ofthe glass holder 6 to the jaw 2 by means of the nut and bolt, it will be seen that the glass may. be adjusted as desired to properly focus same relative to the dial. It will further be apparent that the clamp 1 may be readily turned about the telephone column in focusing the glass, and that the entire attachment may be easily and quickly removed from the j telephone column. It will further be noted that the flash light may be easily and quickly removed and a new one applied upon the battery becoming exhausted by merely moving the flash light downwardly out of the jaw 3. It will thus be seen that the magnifying glass is frictionally supported and no manipulation of parts is. required in removing or applying same. The slot 11 which is of substantially U-shape provides spaced walls which are of such angular relation, as to hold the handle of the glass against turning, while the walls resultant from the slots 9, provide stops which prevent axial movement of the handle. Therefore, in removing or applying the glass, a mere bodily upward or downward movement thereof is required. The slots 9 moreover but slightly alter the appear- .ance of the glass handle and do not detract from the usual a pearance thereof.
In the, modifie form of the invention it will be noted that a clip 20 is emfployed of substantially cu shape which is ormed of sprin metal an which has arms or jaws 21, two 0 which are flat at their central portions while the other two are concaved as indicated at 22. The handle 23 of the magnifying glass has each of its four sides shaped to correspond to the recited shapes of the arms or jaws 21. The clip 20 may be spot. welded or otherwise rigidly secured to the jaw 21' which corresponds to the jaw 2 in the preferred form of the invention. The free end 24: of the handle is slightly rounded so as to enable the handle to be easily inserted into and out of the jaws, and due to the two opposed flat surfaces of the jaws and of the handle it. will be noted that-the glass will be held against turning while the concaved i'aws allow slight vertica movements of the ass in focusing same.
What is claime is:
A magnifying glass attachment for dial telephones including a support formed for attachment to the telephone column, a projection carried by the support and extending outwardly therefrom, a substantially L-shaped holder having a substantially vertical U- shaped'slot in one of its arms which extends through the top thereof and which forms a pair of spaced opposed walls, means to conmeet the other arm of the holder to the projection of the support to enable the have vertical swinging movement whereby to position the glass in a plane parallel to the plane of the dial and a member for supportmg a magnifging glass having a pair of spaced oppose slots which receive the walls of the slot of the holder so as to support the member against turning and to permit same to be removed from the holder by mere upward movement out of the slot.
In testimony whereof I aflix my signature.
. ADA BRADFORD.
