C. L. HIBBA RD. TALKING MACHINE. APPUCATION FILED- 03.19, 1924/ 1,186,190. Patented June 6 1916.
UNITED STATES PATENT OFFICE.
CHARLES L. HIIBBARD, OF PHILADELPHIA, P ENNSYLVANIA, ASSIGNOR OF ONE-HALF TO FREDERIC W. HAGER, OF .PIHLADELIEHIA, PENNSYLVANIA.
TALKING-MACHINE.
Specification of Letters Patent. I Patented June 6, 1916.
Application filed December 19, 1914. Serial No. 878,092.
To all whom it may concern:
Be it known that I, CHARLES L. Brennan,
a citizen of the United States of America, residing at the city of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in. Talking-Machines, of which the following is a specification.
- My invention relates generally to talking machines and has particular reference to a connection between the tone-arm and sound-box, by which the latter may be readily and conveniently set to cooperate with either the zigzag or the hill and dale type of record.
The accompanying drawings will serve to illustrate several forms of a device suit-.
able for carrying my invention into effect. I wish it understood, however, that I do zo not limit myself to the precise details shown,
as various changes may be made therein, without departing from the spirit and scope of my invention.
In the drawings, Figure 1 is a view in ele vation showing the preferred form of connection in use, the sound-box being arranged for reproducing from a hill and dale record. Fig. 2 is an enlarged detail plan view, showing the sound-box shifted for use with a. zig-zag type of record. Fig. 3 is a front view thereof, and Fig. 4 illustrates the shaped end of the tone-arm with which the sound-box is adapted to be coupled or connected. Fig. 5 is a plan view of a modification, in which the sound-box is shown in position to cooperate with a hill and dale record, and Fig. 6, is a similar plan view, showing the sound-box as it would be arranged to reproduce from a zigzag type of record.
Referring now to the drawings, 1, represents a portion of the casing of a talking machine, 2, the turn-table carrying the record 3, 4, the tone-arm mounted at 5, in the usual manner to have movement in vertical and horizontal planes, and 6, the sound box provided with a lever at 7 terminating in a needle or stylus 8, arranged to track in the groove of the record.
In order to adapt the sound-box to cooperate with the two well known commercial types of disk record, one, the lateral cut, known as the zigzag record and the other, the up and down out, known as the hill and dale record, it is necessary to place the sound-box in such relation to the record, that thestylus lever may respond fully to the undulations of the sound groove and the sound-box is accordingly arranged as in Fig. 1, or in Fig. 2, the position in which it is shown in Fig. 2, adapting it for the zig-zag record and in Fig. 1 for the hill and dale type.
the other 11, an angular extension therefrom, as shown.
Formed in part with or otherwise secured to the sound-box, there is a short tube 12, which leads from the diaphragm chamber thereof and is shaped and proportioned to telescope into either of the terminal branches 10, and 11, of the tone-arm, being firmly held therein from turning by a setscrew 13, which is adapted to fit in a notch 14, formed in each of the branches.
In shifting the sound-box from one positionto the other, it is desirable for many reasons, to avoid changing the length of the tone-armand as it is necessary to close one branch of the arm when the sound-box is arm to a depth sufficient to close the open- To enable the sound-box ,to be thus relatively. placed and quickly ing through the other branch 11, and is then positively checked by the set-screw 13, of the extension tube 12, entering the notch 14:, of the branch tube of the tone-arm.
VVhen the sound-box is shifted, by being coupled with the angularly disposed branch 11, of the tone-arm, as in Fig. 2, to cooperate with thezig-zag type of record, the tubular extension 12, of the sound-box telescop'es into the tone-arm branch 11, until it contacts with the far inner wall of the branch 10, and closes the opening through the latter, the end 15, of the extension 12, being shaped, as shown, to clear the sound passage through the tone-arm proper. In
ing done by the end of the sound-box extension in contacting with the inner Wall of the other branch tube but it serves to set the box at the proper angle and secure it against in dependent play or movement.
In the modification illustrated in Figs. 5 and 6, the tubular extension of the sound box is shown bifurcated, one branch 16, when coupled. in telescoping relation with the open end =7, of the tone-arm, serving to adapt and position the sound-box for use with the hill and dale record as shown in Fig. 5, and the branch 18, When similarly coupled, adapting it for use With the zigzag type. In this, as in the other form of coupling, the branch not in use, is closed by the telescoping end of the cooperating memher, as above described.
An important structural feature of the invention consists in inclining the tubular extension of the sound-box at such an angle to the body thereof as to cause the box, when connected through either branch of the coupling, to take a fixed and definite position with relation to the record, thus relieving inexperienced users from the necessity of adjusting the same.
As the method of use and operation will be apparent from the foregoing, further description thereof will not be given.
Among the important advantages of the invention may be mentioned, the extreme comprising two members, one of Which ter ininates in angularly disposed branches each suitable for receiving the other member in telescoping relation, the last mentioned member being adapted to extend through any one of the said branches and form a direct connection beyond said branches With the body of the branched member.
2. A tubular coupling for a sound-box comprising a tone-arm terminating in two angularly disposed branches, a tubular extension, from the sound-box adapted to extend through either of the branches to a depth suflicient to close the other branch and form a direct connection beyond the same with the tone-arm proper, each of the branches being provided with means for holding the sound-box in playing position.
