Application flied August 22,1906. Serial Nc- 331,678.
lie ii known that .losm'n Newconu .Ilmoximn', a. citizen of the United Suite r siding at East Orange, in the county of Essex and State of New Jersey, has invented new and useiul lmprovcmcnts in Cleaning ihilfltllillblltfi tor Records of Sourid-Reproducing Inadapted to this type of instrument, having means whereby it. may be easily assembled in operative relation to the record-disk and removed therefrom when desired. In the practical use of such disk-rec0rd, souud-reproducing instruments objection exists that the reproduction is clouded; that is, it is not as clear and distinct as it. should he, and this difliculty arises because oi the fact that the sound grooves are not perfect! y clean, small dust particles collecting therein. Very slight particles of dust in the grooves detract n'iatcrially fromtheclearness of the sound reproduction, and so far as I. am aware this dit culty has never heretofore been taken career in disk-record instruments.
My invention consists in a cleaner adapted to be supportcd in operative relation to the record disk, as hereinafter described. I
That which I regard as new will be set forth in the clauses of claim appended to the dose iption'.
In the accompanying drawing illustrating that which 1 regard as the host known embodiment my invention- -Figu" c it is a perspective view of the cleaning implement; Fig. 2 a ide ehwation thereof; Fi". 3 a front elevation thereof; Fig. i a rear elevatimi; Fig. 5 illustrates the same connected to the SUtllltll)t)J of the .in strument; Fig. (5 a perspective of a disk-record, sound reproducing apparatus with the cleaning-implement. in operative relation to the record; and Fig. 7 a similar view showing the sound-box/mid the cleaning-implement attached thereto shii't ed to inoperative position.
In said drawingthe reference numeral 1 designates the rccordsupport; 2 a standard in which is mounted the swinging sound-box carrier-arm 3, which is adapted to be' swung over the disk-record to support the soundbox and the needle carriedthereby in operative relation to the disk-record when the instrument. is in use, and L0 be swung away therefrom to permit. the insertion and removal of records. The soundbox- 4 has a pivotal connection with the supporter-arm 3 whereby it may be swung to the position shown in Fig. 7 prior to swinging the supporter-arm avay to permit. the introduction or removal of a record, so that in the swinging movement the needle will not traverse the record anti whereby it nisy be swung down to the yosition shtiwn in Fig. 6 when the instrument is in operation.
Supported by the sound-box is the cleaning instrument- 5 which, preferably, consists of a camel-hair brush 6, providedwith means of attachmentto the sound-box, although the actual material of the cleaner may be various, such as felt or other suitable material. As shown, the eleaning implemcnt is attached to the sound-box and moves in sweeping contact with the record disk in advance of the reproducing needle 7 and s rves to effectually clean out the sound groov'es'sothat the needle has perfect contact and a clear and distinct sound reproduction is secured. 1 l
The cleaning brush or implement is provided, as
stated, with means whereby it may be secured in operativc position to the sound-box. This means, as shown, consists of abuse-member 8 extending laterally from the top of the brush to bear against the circun'iierential face 9 of the rim of the sound-box and arms 10, 11 at the opposite ends of the base-member whichemhrace thesound-box rim, one of which arms is provided with an inwardly turned finger 12 to takeover the annular flange 13 of the rim, and the other arm is provided with a recess 14 to take over the stem of one of the screws 15 which pass through the sound-box and the head 16 of which, when screwed home, engages the said arm 11, thus confining the cleuuing-impicmcnt securely in place.
The device may be'readily attached by simply loosening-up the scrowloand fitting the intm'ned end 12 of the arm 10 over the annular rinnflunge 13 of the soundbox and then slipping the slot in the arm 11 over the screw 15 and turning the scrcwhome. lFOYICIilOVfll the i operation desZ-i .icd is reversed. It will thus be seen that the c]caning-iinplement. is provided with u.-\'ery. simple means whereby it may be connected to the soundbox in operativerelation to the disk-record.
The cleaning'implement of my invention serves to thoroughly clean the grooves and a clear and distinct reproduction is secured. The device is a simple one and'easily attachable and detachable.
Having thus described the invention, what I claim 1. In a soundreprochicing instrument, a cleaning-implement comprising eleuningannteriu] and attaching means eonslsting'cf arms adapted to embrace the sound-box, one of such arms having an iuturued end and the other .11 slot.
