Application filed March 12, 1907. Serial No. flfilflw.
dent oi the hm'ough oi lllerchantville, in the county oil: llzuuden and State of New Jersey, have invented certain new and useful lmp rovements in @ounterbalanced Soundltoxes, oi which the following is a lull, clear, and complete disclosure.
The object of my invention is to provide means for preventing heavy sound boxes or those oit' excessive weight from causing the stylus needle thereof from exerting the excessive pressure upon the record.
For a lull, clear and exact description of one term oi my invention, reference may be had the following specification and. accompanying drawings, in which lilre refercn-oe characters refer to corresponding parts.

in the drawings Figure l, is an elevational oi my invention, showing the fragmentary portions oi the adjacent part-s oi the machine; Fig. '9; an enlarged view of my invention, showing the sound box turned hacl; on the sound conveying arm-guild Fig.
8 an enlarged end view oi the sound box turned down into its operative position on the record. X
It is sometimes customary in the art to make difierent parts of a talking machine, especially those parts which come in contact with the sound waves, of excessive proportions in order to produce a clearer tone. In some cases the sound box is 'enlar ed to such so as to cause the stylus no Is to exert too orciblc or abnormal pressure upon the record, thus destroying the revolution of the latter, or, retarding the same or doing some other damage to interfere with the open ativeness of the machine.v To obviate said disadvantages I have provided means for taking that much of the wci ht oil the sound box as the same is heavier, t an the ordinary or regular size sound box in common use, or in other words the excgsslve welght thereof.
Otherwise the peculiar construction of this device, the parts ofwthe mac in m y e c structed like those of variable designs in;
common use: Iuthe-one .haveillustrated, however, a supporting arm to attach to a cabi'netgfl, and to the upper end of the sup- 'box will cause the lever 12 to swing pivot until the'exc'esslve weight of the sound porting arm is a swinging arm 3 mounted to swing in a horizontal plane and having pivoted to its free end a ll shaped tuhe 4:, by the usualhinge 5, the free end of the ll shaped tube having mounted thereon the spring 4r. The sound hex 6, as heretofore stated is out heavy or excessive weight, other-. wise being like the construction oi any of the several sound boxes common in the art. To the diaphragm 't' is connected the stylus 8 in the usual manner, having a needle Q inserted in the outer end thereof.
As shown in Figs. 1. 3 the sound box is in its operative position having the stylus needle 9 resting in, grooves ot the record 10, which latter is mounted in the usual manner upon theturn table ll. The lever 12 having arms l3 and 14s pivoted. at its intermediate portion 15 to the annular face 6' of the sound hon G. l he arms 13 and i l of the lever are curved to he substantially concentric with the annular :tace oi the sound box, when either one out the some is turned to such a position to be coincident therewith. Attached to the extremity it of the arm 13 is the spiral spring 17 whose opposite extremity 1s attached to the pin 18 on a sound Attached to the extremity of the arm 14, is the yoke arm 21 which taken together with the yoke 22, which is a con tinuation of the arm 1d, form a hearing for the roller 23 which is made of wood or other suitable material that will roll readily over the face of therecord without damaging th same. 1
When the machine is not in operation the sound box may be swungback to rest on the extremity of the sound conveying arm 3in the usual manner and in such position there till being no pressure upon the roller 23 the same will be slightly beyond the stylus point 9, due th the springol l having been relieved from, its tension. min the operation of the .inachine, however t e box is turned down, as shown in Figs. 1 and 3S0 the needle will take its ro record. Owing to the act that the roller 23 is beyond the'iend of the needle it will strike the record first and'the weight of the sound or position upon the on its box and the tension on the spring 17 are counterbalanced. The pressure exerted by theneedle when this counterbalancing ac tion takes place is regulated by the adjustment'of the spring 17, which adjustment is arranged to be a permanent one. When the counterbalancing mechanism is first attached the curvature of the arms and their proper dimensions is also determined to a certain standard.
hile not admitting that there is no inve ion in the exact device illustrated and set forth in the above description, yet I wish it directly understood that a lever of other peculiar configurations together with other types of springs may be utilized so long as the device will erform the. result herein described and W111 be within the construction set forth withinthe appended claims.
