' "FWD-BOX FOR TALKING-MACHINES.
ioaooo.
Specification of Letters Patent.
Patented June 30, 1914.
Application filed August 25, 1913. Serial No. 786,445.
To all whom it may concern:
Be it known that I, HORACE SHEBLE, a citizen of the United- States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Sound-Boxes for Illalking-Machines, of which the following is a specification.
The object of my invention is to so con-' Figure l is a view, partly in side eleva tion and partly in section, of an ordinary talking machine sound box illustrating the same as designed for use with a record of the lateral-wave type; 'Fig. 2 is a similar view illustrating the sound box as adapted for use in connection with a record of the hill-and-valley type, and Fig. 3 is an enlarged view of the converting attachment shown in Fig. 2.
.In Figs. 1 and 2 of the drawing, 1 represents the casing of the sound box, 2 the diaphragm thereof, and 3 the usual stylus lever pivotally mounted upon the casing '1 and having one of its arms connected to the diaphragm 2, the other arm being bored for the reception of the stylus 4 usually employed in connection with a record of the lateral-wave type, said stylus being secured in position by means of a clamping screw 5, or othersuitable means. In order to permit such sound box, without changing the angular position of the diaphragm 2, to be em- )loyed in connection with a record of the hill-and-valley type I prefer to use, in place of the stylus l, an attachment such as shown in Figs. 2 and 3, said attachment consisting of an arm 6 having near one end an upwardly extending pin 7 and at the other end a downwardly projecting stud 8 carrying a sapphire point 9 such as is usually employed in connection with a record of the hill-and-valley type. The pin 7 can,
after the removal of the stylus 4, be secured to the stylus lever 3 in the same manner as said stylus. The stud 8 has a stem 10 adapt ed to an opening in the arm 6 and secured therein by means of a clamping screw 11, or other suitable means. In order to secure like results in reproduction With-either type of record, the'sapphire point 9 should, when it is used, be at the same distance from the fulcrum of the lever 3 as the point of the stylus 4, when the latter is used, and in order to effect this result I bend the arm as shown in Figs. 2 and 3, so that the member of said arm which carries the stud 8 shall be in a different horizontal plane from the member which carries the pin 7.
My invention is intended to'be used in connection with a machine having a stylus 4 of a given length, hence as said stylus is always introduced into the opening in the stylus lever .so as to seat against the bottom of said opening, its point is always at a given distance from the fulcrum of said stylus lever.
The diaphragm 2 retains its normal position, that is to say, a position at right angles to the horizontal face of the record, whether the latter is of the lateral-wave or of the hill-and-valley type.
I claim The within described attachment for adapting for use with a record of the hillandvalley type a sound box normally intended for use with a record of the lateral wave type, said. attachment consisting of an arm having at one end an upwardly projecting pin for entering the stylus receiving opening of the stylus lever of the sound box,
said arm being offset at the other end and carrying at that point a downwardly projecting stylus whereby the latter will engage the hill-and-v'alley record at the same distance from the fulcrum of the stylus lever as is the point of a lateral wave engaging stylus of normal length occupying its predetermined position in the stylus lever.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
HORACE SHEBLE.
