Bn'usn ro n TALKING MACHINES.
Specification of Letters Patent.
Patented July 25, 1922.
Application filed April 7, 1921. Serial No. 459,432.
T all whom it may concern:
Be it known that I, THoMAs S. GROW, a citizen of the, United States, residing at Allentown, in the county of 'Lehigh and State of Pennsylvania, have invented new and useful Improvements in Brushes for Talking Machines, of whichtlie following is a specification. I
This invention relates to brush device used in connection with talkingmachines for sweeping the record disks thereof and thusdislodging and removing all dust and-other foreign particles from the grooves of the disk in which the needle works.
The invention has for its object'to provide a very simple an efiici'ent brush device of the kind stated, which can be readily at tached to the machine, and which is so positioned that it does not interfere with the proper operation ofv the machine.
The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.
In the drawing,
Figure 1 is a plan view of a phonograph partly broken away, showing an embodiment of the device and Fig. 2 is an elevation of the device partly in section.
ferring specifically to the drawing, 5 denotes the top or motor board of a talking machine cabinet above which is located the turntable 6 which carries the record disk 7.
9n the motor board 5, alongside the turntable 6, is mounted a small tubular standard '8 having a base flange 9 which seats on said part 5 and is secured thereto by screws or other suitable fasteners. The standard and its base flange are located clear of the tone arm 10 so as not to interfere with the operation of the latter.
The standard 8 supports a rotatable vertical spindle 11 which rises for a short distance from the top of the standard, and in the latter is fitted a wear bushing 12 in which the spindle turns freely. 1
To the upper end of the s indle 11 is attached a horizontally ext/en ing brush-supporting arm 13, the spindle having a transverse aperture through which the rear end of the arm passes. Nuts 1% screwed on the arm to seat against the spindle at diametrically opposite points fasten the arm to the spindle.
The brush is attached to the outer end of the arm 13 in pendent position so as to wipe 'across the top face of the record disk 7 and it consists of a head 15 carrying the bristles 16. -The rear edge of the brush head is formed with a longitudinal opening to seat the arm 13, and the latter carries nuts 17 and '18 between which the brush head seats and is held. The brush head is removable from the arm 13 upon taking off the outer nut 17.
' In order to vary the height of the brush so as to properly locate the arm with respect to the record disk 7, one or more plugs or washare 19 may be placed beneath the bottom of the spindle 11 to elevate the same and the arm 13 more or less as desired.
The top of the standard 8 is apertured to support an upright pin 20 which is located to intercept. the arm 13am], limit its move- ,ment in the direction it tends to swing by the contact of the rotating record disk 7 with the brush;- i
The device is so positioned that the arm 13 may be set to extend transversely of the turntable 6, it being adjusted to such a height that the brush bears lightly on the topsurface of the record disk 7. The length of the brush is such that it extends completely across the recordesurface of the disk, and hence when saiddisk is in motion the brush sweeps the same clear of all dust and foreign particles so that the grooves are perfectly clean and free of dust and other particles which tend to impair thetoneof the machine.
The brush supporting arm 13 will be made i of such length as to adapt the device to the particular make of talking machine to which it is to be applied. The Edison machine will require an arm somewhatlonger than the one illustrated.
When the record disk 7 is to be placed on or removed from the turntable 6, the arm 13 will be swung aside clear of the turntable, leaving the latter entirely unobstructed. The brush, bears so lightly on the record disk that it has no appreciable retarding eff t on the motion of the same, and as the device is also entirely free of the tone arm 10 it does not in the least interfere with the Q i ,azesee operation thereof. The device can also be easily attached to the machine without disturbing any parts thereof.
I 'claim:
A brush device for talking machines of the disk type, employing a rotatable turntable for supporting the record disk; said device comprising a brush, a supporting arm for the brush adjustable toposition the brush across the face of the disk, a rotatable spindle carrying the arm, a support having a bearing opening in which the spindle is loosely and removebly mounted, said support, being mounted alongside the turntable and clear of the same, and a member removably mounmd in the hearing opening and positioned beneath the spindle for determining the elevation of the spindle, the lower end of the latter seating on said member.
in In testimony whereof I ailix my signature. 20
THOMAS S. GROW.
