AUXILIARY DEALING TOOL. 1

Application filed a gust 5, 1927.] Serial Nb. 2'1o,se1.

This invention relates to dial operating de.

vices, and more particularly to devices of this ,character whici-r readapted to be used in the operation of dials for telephoneinstruments or the like. I, a I

The .mova'ble circular plates or dials for telephone instruments are usually provided with a series of holes, each hole having a number associated with it.- To operate the dial, a finger is inserted in a given hole and the plate rotated. until the finger strikes a finger stop, after which the finger is removed and a spring causes the plate to rotate back to its normal position. In certain testing operation's, it is necessary to dial a given num ber repeatedly while closely observing. the apparatus being tested.

Anobject of this invention is to provide a device whereby any given number may be dialed repeatedly with a minimum possibility of error and without looking at the dial, thus enabling continuous and close observation of the apparatus being tested.

Another object consists in the provision of a device of this character which will assist the user by making it unnecessary to insert a finger in a hole of the movable plate thus avoiding abrasion or injury to the finger when continuous dialing is necessary as in testing operations.

A further object is to provide a device which will tend to prevent the useof pencils or other makeshift arrangements, the use of which causes injury or excessive wear to various parts of the dial.

A further ob ect is to provide a device which is simple and inexpensive 1n construction and one which is not liable to get easily I out of order.

These and further objects will be apparent from the following description, when considered in connection withthe accompanying drawing in which certain novel features of the invention appear. 7

Referring to the drawing, Figure 1 is a sectional side elevation of the improved device; Fig. 2 is alike view of a modification of the device; and Fig. 3 is a perspective view of a dial with the improved device in position thereon.

In Fig. 1 of the drawing, the numeral 5 designates a top swivel portion or a head which forms a finger-piece. The member 5 may be formed as shown in Fig. 1 and composed of any suitable material, such as hard portionS, thefbotto 'n of which of the sleeve 6.

Thelcylindrical men her 7 is shownas havinga thickened upper V I, p v "lies in the same horizontal plane'asthe end ofthe sleeve 7 rubber. An yinteriorly threaded tubular 6. A chamber is formed in theflower portion of the cylindrical member? and the wall of this chamber has a plurality of longitudislots 9 provided therein. A'cric'um'ferentia'l "groove '10 extends about thefoutersurfac'e ofthe wall and is provided- "for the purpose of engagingthe edge of an o'pening'fin the 'filOVtIblG plate of adia'l; The slots 'o serve to provide suiiioient flexibility to permit the seating of the circumferential groove of the wall agamst the'edges of the openings in the movable plate. The elasticity of said wall is r V such that it is retained in it is removed by hand.

The shank of a screw .11 engages the interior threads of the tubular sleeve 6, while the head of the screw andassociated washer are seated on the shoulder provided by the flush portions of the member 8 and the end this position until In Fig. 2 the swivel head 5 may be com posed of metaland be provided with a concave portion 12 in its top to form a fingerengaging surface. The sleeve 6, similar to Fig. 1, extends through the top of the joy lindrical portion 7 and its interior threaded surface engages the shank of the screw 11. In Fig. 2, however, the head of the screw 11 clamps the flat portion of the member 13 against the bottom of the memberv 8. The

member 13 has a plurality of downwardly extending resilient prongs 14, each of which is positioned against the walls of the chamber portion of the cylindrical member 7 at a point intermediate the longitudinal slots 9. These prongs serve to permit sufficient flexibility for the lower portion of the cylindrie V cal member to engage the edge of the openings in the movable plate of a dial and also tion to normal.

provide suflicient rigidity to restore said por- Theimproveddevice is applied to the dial 14 of. a telephone instrument in the manner 7 indicated in Fig. 3. The bottom portion of the cylindrical member comprising the sep- 'arated Wall portion is inserted into'the desired opening of the movable plate and it is i rotated until the device strikes the stop-piece construction, operation and many .15, after which the movable plate is returned automatlcallyr In testing circuits or devices connected therewith, it Will be apparent that after the improved device has been inserted to watch the dial to it will not be necessary see if the proper digit is dialed, permittingcloser' observationof the swltch'or other device which may be under test.

' From the :t'oregoing,it is thought that the advantages of the'herein described and delineated invention will be apparent to those skilled in the art without 'iurtlier description, and it Will be" understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any advantages of the invention. 1 'VVhat is claimed is: 1 r
