tachments, and its primary object residesl -in the provision of a brush of simple construction adapted to thoroughly clean the grooved face of a sound record while it is A beingl revolved by the motor of the phonograp instrument towhich it is attached.
With theabove object in View, my invention comprises a brush made of any suitable material, which is connected with a spring to receive a gentle downward pressure for its frictional contact with the record.
The-spring is mounted upon the casing or motor-box of the instrument, and is rotatable about an upright axis for its adjustment to move the brush into and out of contact with the face of a record supported upon the revolving table of the phonograph'.
The brush is pivoted on the spring for its self-adjustment to follow the usual wabble of the record, and its pivotal axis is preferably arranged nearer its forward end to cause it to tilt when it is separated from the record, and thereby facilitate its subsequent movement onto the face thereof.
An embodiment of my invention is illustrated in the accompanying drawings in the several views of which like characters of reference refer to corresponding parts and in which Figure 1 represents a fra 'mentary perspectlve view of a phonograp to which my attachment is applied, l
Fig. 2, a fragmentary plan view of the phonograph showing the attachment in its operative position with relation to a soundrecord supported thereon,

Specification of Letters Patent.
Patented Jan. 21, 1919.
Application filed July 10, 1917. Serial No. 179,649.
The reference character 2 designates the' motor-box or casing of a phonograph instrument, 3 the revolving record-supporting table thereof, and l the sound-box which at the end-of a pivoted arm' 5, carries the stylus 6 traveling through the groove of a recorddisk 7 supported upon the table 3.
My attachment consists of a base-plate 8 secured upon the top of the. casing by means of screws or other fastening devices.
The plate carries an upright spindle 9 which is threaded at its upper end for the reception of a tension nut 10. A C-spring 12 has adjacent its bow two alined openings to admit the spindle for its pivotal support upon the base plate, the nut 10 engaging the upper surface of the springto regulate its tension.
The arms of the spring are of uneven length, the upper one 13 eing sufficiently long to project over the revolving table of the instrument to which the attachment is applied.
Pivotally suspended from the end of the arm 13 is the record-cleaning brush 14 which is made of elongate form to traverse the grooved side of the face of a recorddisk supported on the table.
The brush in its preferred form, is made of a wooden core 15 covered with plush or other material, 16, suitable to enter the sound grooves of the record, and longitudinally grooved to 'receive opposite edges of a metal holder 17 of ehaniel section to which it is attached.
The connection of the brush with the arm of the spring 13 which is curved to permit of a limited pivotal motion of the same, is established through the instrumentality of a U-shaped yoke 18 secured to the spring and straddling the brush.
A bolt 19 secured in alined openings of the yoke extends loosely through openings in the sides of the holder and a corresponding space in the core to provide the ivot about which the brush may move to a just its position in accordance with the transverse slant of the record.
The pivot is, as hereinbefore explained, arranged nearer to the forward end of the brush so that when the attachment is in its inoperative position as shown in Fig. 3, the
brush which in this position is separated from the record, will slant troni its rear end upwardiv to facilitate its moving onto the tace' of the record when the spring is subseouently moved about its pivot to bring the or into 'the operative position withrelation thereto.
stop 2O on. the base plate determines the two adjusted. positions' of the spring, by the short lower arm thereof, and a pad secured to the end of the long arm of the 4spring cushions the upward movement of the brush, principally for the purpose of eliminating noise.
AThe operation of the attachment will be readily understood trom the above descrip.- tion oi: its construction..
ll/Vhen the brush is not in use, it is in the position shown in Fig. 3, tilting slightly upwardly .to aoilitate'its movement' onto the -ota record supported. upon the revolving table et the phonograph instrument.
il'il'ien it is desired to clean the record, the signing is. moved about .its pivot until its short arm engages the stop 20 and the brush extends transversely of' the grooved side of the record as shown in Figs. i and 2.
.The soft material covering the core of the brush, enters the sound grooves of' the record and thoroughly cleans the same from dust and other 4foreign matter by the rotary movement oi' :the same, it being understood that the spring presses it gently into fric-v tional contact with therecord and that itspivotal connection with the spring permits otitsi'ollowing everj7 deviation of. the record +trom 'the plane in which it has 'its rov tary movement.
The nut at the end of `the spindle` pro-'- vides ready` means to vary the pressure of the brush uson the face of the record, and
to change the position of the same in. ac-
cordance with the height of the record above the top oit the casing upon which the attachment mounted through the medium of the base-plate. i j
Having thus described the construction and operation of my improved phonograph vbrush in the best form at present known to me, l desire lt understood that variations in the construction and arrangement of the parts thereof, maybe resorted to within the spirit-,of the invention as 'deined in the following ciairns, i
