specification of Letters Patent.

Application tiled September 10, 1912. Serial No. 219,510.
To all 'whom it may concern Be it known that I, JOHN SoN'rHarMan, a citizen of the United States, and a resident of Lincoln, in the count of Lancaster and State of'Nebraska, have lnvented a new and I'mproved Telephone-Directory, of whlch the following is a full, clear, and exact de scription.
This invention relates to telephone directories and has reference more particularly to a4 evice of this class which comprises a plurality of circular members carrylng reference characters and provided with means whereby any desired reference is rapidly found.
An object of the invention is to provide an inexpensive and compact telephone directory, sim le and durable in'its construction, an whic can be easily attached to a telehone and' will not, interfere with its action or add much to its bulk.
Another objectof the invention is to provide a telephone directory carrying telephone references and addresses of such parties with whom most of the telephone connections are made, and to locate such references when desired with a minimum expenditure of time.
A further object of the invention is to provide a device to which telephone references may be easily added or replaced, the addition of the reference not requiring any chan e in the structure of the device.
Re erence is to be had to the accompanying drawings forming a part of this speciication, in which like characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a face elevation of an embodiment of my invention partly broken away to expose one of the reference disks, the dotted position of the disk showin the position when looking for a desired tele one number; Fig. 2 is a part of the device in section taken on the line 2 2 in Fig. 1; Fig. 3 isan enlarged perspective view of a part of the reference carrier; Fig. 4 lis a perspective view of the roller with the loop member; and Fig.v 5 is a perspective view of the telephone Iprovided with my device.
Before procee ing to a more detailed description of my invention it must be understood that the drawings submitted show only a special type of a telephone and' that my device may be attached to any form of a telephone by a corresponding modification ofthe means of attachment of. my device. The reference carriers may be circular or of any other shape, and, similarly, the casing for said disks.
Referring to the drawings, 10 is a casing preferably cylindrical in shape, having its ends formed by means of circular end walls 11 and 12 and its lateral surface 13 only semi-circular; thus an opening is left in the casing on its lateral surface between the end walls 11 and 12. Loosely fitted in said casino' is a plurality of circular disks 14 provi ed with an engaging edge ring 15 straddling the ed e of the disk 14, the diameter of. said ring eing a little less than the interior diameter of the casing 10. The disk 14 is provided on one of its faces with a circular pieceof paper having the roper references printed or otherwise provided on this paper. The paper may b secured to the disk by pasting same on the disk, or clamping means may be provided on the disk for maintaining the paper on same. The ring 15 is provided wlth a fiange 16 projecting above the lateral surface of the casing 10, and is provided with a letter stamped in said flange, or otherwise secured to same, and indicating the name of the party whose name begins with the same initial.
The disks 14 provided with the rings 15 are interposed by means of small circular disks 17 so that the rings'15 bear easil with their sides against the face of the disly: 17. Thepurpose of the smaller disks 17 is to prevent interference between any air of consecutive rings 15. The so-forme a1- ternate series of circular disks 14 and 17 are eccentrically mounted on a pin 18 rigidly fixed in the walls 11 and 12 of the casing 10 near its lateral surface and projecting out of the sides. The edges of the disks 14 and 17 are normally at the same level with respect to the lateral surface of the casing 10. The disks 14 being eccentrically mounted near the lateral surface of the casing 10 when swung on the pin 18 out of the casing will expose the maximum of their face carrying the referencmhxle the disks 17, being fixed on the pin 18, will not he. displaced. The projecting pin 18 at one of its ends carries a wire coil spring 19 having one of its ends fixed on the end wall. 11; the other end of t-he said spring 19 forms a loop member 20 about the lateral surface of the casing and resting on the other end of the projectin pin 18. The part of the loop 20 para-lle to the lateral surface `of the casing 10 is provided with a rubber roller 21. The loop 20 and roller 21, by means of the coil spring 19, are continuously forced toward the' lateral surface of the casing 10. rlhe casing 10 is also rovided with a split ring 22 having two en flanges 23 formed in the split and adapted to receive a bolt 24. The ring 22 is also provided with a projecting portion 25 in line with the lateral surface of the ring and riveted or otherwise secured to the wall 12 of the' casing 10. By means of the solit ring 22 the device is placed' on the body ofthe telephone 28 and cla-m ed to same by the medium of the bolt 24 (see igs. 1 and 5) The lateral surface of the casing 10 is also provided with a hooked member 2G' adapted to receive the paper 27 to be used for memorandum when necessary.
My device, iis-shown in Fi 5, is placed so as to have the indicating ane 16 provided with the letters of thealpha et to face the erson using the telephone. When a num er is to be called the initial of the name of said artybeing found on the indicator fiange, yA forcing this--.flangcto `the left (Fig. 1) the face ofthe disk 14 carryin' thepapcrs with the printedl narines, telep one,
number and address, is exposed and can be readily seen and the desired artys name is easily found, as shown in otted lines in Fi 1. By the outward movement of the -dist 14 the rubber roller 21 is also forced away from the lateral surface of the casing 10 and thereby increases the tension of the winding of the coil sprin 19 so that when the finger holding the in i'cating flange 16 is released the spring 19 forces the disk 14 to its original position by meiins of the roller 21,` as can be easily seen from the drawinffs.
It is readily seen that with my device tie expenditure of time required to find the numbers of the parties with whom most of the telephone connections are made is diminished to a minimum; the reference being` attached to the telephone itself cannotbe mislaid,` and any desired additional reference can be easily made either by rinting directly on the aper fixed to the disk 14 or by pasting or ot erwise securing a new paper t isk on the disk 14.
Having thus described my invention, what l claim as new and desire to secure by Letters Patent is :--A
