PHONOGRAPH.

Patented Get. 9, 191?.

Application filed May 10, 1913. Serial No. 766,697.

To all whom it may concern:

Be it known that I, IRWIN D. PIKE, a citizen of the United States, and a resident of West Orange, Essex county, New Jersey, have invented certain new and useful Improvements in Phonographs, of which the following is a description.

My invention relates to phonographs and more particularly to an improved cleaning device which, while it is adapted to be applied to numerous types of phonographs, is especially designed for application to Edison phonographs employed for commercial purposes.

The principal object of my invention is to provide an improved construction whereby it will be insured that the cleaning mate rial of the cleaning device will be maintained in contact with the record or blank when the reproducer or recorder of the pho-' nograph is in operative position and will be removed from such contact when the reproducer or recorder is moved from .operative position. My invention also contemplates the provision of a simple and 1mproved cleaning device which may be made as an attachment; and the provision of an improved brush which forms a part of the cleaning device and which may also be made as an attachment capable of being readily applied to and removed from the rest of thecleaning device, whereby, when the cleaning material of the brush becomes Worn, the latter may be quickly replaced.

Other objects of my invention reside in the construction of parts and combinations of elements hereinafter more specifically described and set forth in the appended claims.

In order that my invention may be more clearly understood, reference is made to the accompanying drawings formlng a part of this specification and in which Figure 1 is an end elevation, partly in section, of a phonograph showmg one orm of my improved cleaning device appl ed thereto, parts of the phonograph being omitted; and

Fig. 2 is a view in perspective of the cleaning device detached.

Referring to the drawings, reference character 1 represents the base plate of a phonograph which is provided with a standard 2, carrying at its upper end the usual back rod 3. A sleeve 4 is rotatably mounted on the back rod 3 and is secured tothe carrier arm 5, preferably being integral therewith. Reference character 6 represents the sta tionary front guide rod which is adapted to support the forward end of the carrier arm 5. The arm 5 is provided with the usual feed nut (not shown) which is adapted to engage and disengage a feed screw (not shown) when the arm 5 is lowered and raised. A spectacle frame 7 for carrying the recorder and reproducer is pivotally mounted on a stud 8 carried bythe auxiliary arm 9, which arm is pivoted on a bearingcarried by the carrier arm 5 adjacent the forward end thereof. Reference character 10 represents the lifting lever which is preferably rotatably and slidably mounted upon the forward guide rod 6, this lever preferably being provided with a passageway through the lower end thereof through which the said guide rod passes. The lifting lever is preferably provided with a projection or cam portion 11, the function of which will be hereinafter described. A link 12 is pivotally connected at one end to lever 10 as by means of a screw or pin 13, and is pivotally connected at its other end to the carrier arm 5, the latter end being preferably mounted on the bearing on which the auxiliary arm 9 is pivoted. Link 12 is mounted for free rotation about pin 13 and the bearing therefor 0n arm 5. By this construction a toggle joint is provided, the central point of which is the pin 13, and the two arms are the. link 12 and the portion of the lever 10 between rod 6 and the pin 13 respectively. By forcing the lever 10 to the right, the toggle is straightened out and the carrier arm raised, the stylus of the recorder or reproducer being raised out of its engagement with the record or blank 16; while by movement of the lever to the left the toggle is opened out and the stylus of the recorder or reproducer lowered into engagement with the record or blank. Movement of the lever 10 to the right and left is limited by a suitable bracket 14 suitably secured to carrier arm 5, which bracket is provided with suitable projections adapted to cooperate with a pin (not shown) on the lifting lever 10 for this purpose. Suitable means such as a screw 15 is provided for holding the link 12 on its bearing on carrier arm 5. The structure generally described above is the sameas that disclosed in Patent No. 1,023,250, granted April 16,

1912 to Charles L. Hibbard, to which reference is made for a more detailed description.

When a machine such as described above is used for recording, the chips accumulate upon the recording blank and interfere with the stylus, thereby preventing the best results from being obtained. The chips and fine wax-like material are also liable to blow about the room and upon the dictators clothes. Also, when the machine is used for reproducing, any dust or dirt which may have collected in the record grooves of a record will interfere with the reproducing stylus and impair the reproduction. Accordingly, I have devised an improved cleaning device adapted to be attached to machines such as the one herein described, for obviating the above objections. The cleaning'device is designated generaly by reference character 17 and comprises a light arm, of suitable metal, provided at one end with a hub or bearing 18. Intermediate its ends the arm is bent, whereby two substantially straight portions 19 and 20 substantially at right angles are provided. The end of the arm opposite bearing 18 is provided with a projection or tab 21, preferably formed integrally therewith, for supporting the brush. The straight portion 19 is provided intermediate its ends with a cam portion 22 and a spring 23, the latter preferably being in the form of a fine straight spring wire secured at one end to the arm and extends substantially at right angles therefrom. The brush is designated generally by reference character. 24 and preferably comprises a metallic tubular member or ferrule 25, within one end portion of which the cleaning material 26 preferably of camelshair, is tightly held by compressing the material of the said end portion. The other end portion of the tubular portion 25 is adapted to be slipped over the tab 21 to frictionally engage the same to hold the brush on the arm 17 in the position shown. To further insure that the brush will be held in place on arm 17, the ferrule 25 may be provided with a spring piece or clip 27 secured thereto or formed integrally therewith. Clip 27 extends longitudinally of ferrule 25 and its'free end portion is bent inwardly to occupy a position in line with the opening of the ferrule. It will be apparent that on slipping the ferruleonto the tab or projection 21, the end of clip 27 will spring over that edge of portion 20 of arm 17 opposite the tab 21 and thereby hold the brush in the position shown. Ferrule 25, however, may be made to fit tab 21 so tightly as to render the use of the clip 27 unnecessary, in which case the latter is omitted. When the bristles of brush 24 become worn, the brush may be readily and quickly removed from arm 17 and replaced by a new one.

masses Refering to Fig. 1, the cleaning device is applied to the phonograph by removing screw 15 and the upper end of link 12 from the bearing for the latter on carrier arm 5 and slipping hub 18 of the cleaning device over this bearing and then replacing the end of link 12 and screw 15 in the positions shown. Vhile the arm 17 is designed to rotate freely about its pivotal connection with the carrier arm 5 and gravity tends to force it toward the position shown in dotted lines in Fig. 1, with the cleaning material in engagement with the record or blank 16, the spring 23 bearing against the under side of carrierarm 5, cooperates with the latter to insure that the brush will be brought into operative position with the cleaning material 26 thereof held in contact with the record or blank 16 under a light pressure when the recorder or reproducer is in operative position.

\Vhen lever 10 is turned to the right to the position shown in full lines inFig. 1 to straighten out the toggle and thereby move the auxiliary arm 9 to carry the sound box, either the reproducer or recorder to inoperati e position, the cam 11 on lever 10 will engage the cam 22 on arm 17 and act to raise the latter in opposition to the action of spring 23 and thereby move the cleaning material 26 from contact with the record or blank 16. When the toggle is opened by moving lever 10 to the left, the parts of the phonograph will assume the positions shown in dotted lines with the stylus of the reproducer or recorder in engagement with the record or blank 16, and gravity and the spring 23 coacting with carrier arm 5 will force the arm 17 to operative position with the cleaning material 26 of the brush in engagement with the record or blank 16.

The term sound box where used in the specification and claims is intended to denote either a reproducer or recorder.

While I have shown my improved cleaning device applied to a special type of phonograph, it is, of course, understood that it is applicable to many other types. It will also be understood that my invention may be embodied in many forms other than the one herein shown without departing from the spirit of my invention and the scope of the claims.
