- Specification of Letter: Patent.

Patented Sept. 11 1906.

Applioatio'n filed May 3. 1904. Eerie-1N0. 206,117.

To all whom it may concern.-

Be it known that 1, Louis P. VALIQUET, a citizen of the United States, and a resident of the city of New York, State of New York, have invented certain new and useful Imrovements in Safety Devices for Soundoxes for Talking-Machines, of which the following is a full, clear, and complete disclosure.

The object of my invention is to rovide a device in connection with soundoxes for talking-machines such that the stylus of the sound-box will not rest in contact with the record or the turn-table when the machine is not in use and whichwill also prevent the needle, stylus-bar, and diaphragm from becoming injured should the sound-box and amplifying horn or tube be dropped or otherwise receive rough handling.

A further object of this device is to prevent the records from being injured by the needle or stylus if the sound-box should be suddenly dragged across the record-disk transversely to the record-grooves.

Briefly my invention comprises an attachment for a sound-box which 18 preferably pivoted thereto, but which may be manually operated or may be made automatically operative and inoperative by removing the soundboX and needle from said disk and by the movement of the recorddisk.

For a full, clear, and exact description of different forms of my invention reference may be had to the following specification and to the accompanying drawings, forming a part thereof, in which- Figure 1 is an elevation of a sound-box and a portion of the amplifying-horn and showing the record in section. Fig. 2 is a rear elevation of the same sound-box shown in Fig. 1. Figs. 3 and 4 are detailed views of the means for retaining the safety device in its operative- Fig. 5 is a front elevation of a sound-box embodying'another form of m invention; Fig. 6, a rear elevation thereo Fig. 7, a transverse sectional View; Fig. 8, a view of the safety device detached from the sound-box; Fig. 9, a view showing a modified form of the safety device or guard, and Figs. 10 and 11 views showing another form of safety device.

Referring to the drawings, the numeral 1 indicates asound-box of any'preferred construction having the usual amplifying-horn attached thereto,-said sound-box being supported by the usual pivoted arm 3. However, I do not wish to be limited in the application of the different forms of my invention to this type of re reducing mechanism, as the same is applicab e to any form of reproducing mechanism, including that known as the hollow-arm type, as well as to the ivoted-arm type, above referred to, in whic the ampli- 4 ed, as indicated at 6, so that said end may rock upon the record-disk without injuring the same. As means for keeping the arm 4 in its operative position I counterbore the upper end of the arm 4, as indicated at 7, and

lace inside said counterbored section a circuar spring 8, the ends of which are turned at right angles and one end of which is adapted to engage a hole. or recess 9 in the arm 4, the other end being turned at right angles and engaging a similar recess in the casing of the sound-box. The size and tension of this spring 8 is such that when the stylus is not in contact with the record-disk the arm will assume a substantially vertical position, and

will therefore form a post or support for the sound-box; but when the record is rotated by the motor to reproduce the sound the lower end of said arm will be carried to one side until the point of the stylus comes in contact withthe record. The arm 4 will therefore rest u on the record and drag over the surface of tlic same with a light pressure without in any way injuring or interfering with the action of the sound-box or record. A stop 23 may be provided to limit the movement'of the arm 4 in one direction. It will thus be seen that I have provided a simple and efficient safety or protecting device for the stylus-bar of sound-boxes which will al-, 1

ways be in position to protect said stylus when the sounds are not being reproducedfrom the record; but when said record and the sound-box are operative the safety device will be automatically thrown out of action.

In Figs. 5 to 9, inclusive, I have shown a modified form .of my safety device which is adapted to be operated by the fingers "ofthe person using the talking-machine. The numeral 10 indicates a vertical arm which is similar in shape to the spring 8 and has onebent end entering a recess 15, the other end being adapted to enter a corresponding recess 16 in the sound-box casing 1. By providing the upward extension 12 the arm 10 may be inclined so that the same will not contact with the record when the sound-box is in use; but the spring 14 is of suflicient strength to move the arm 10 and the upward extension thereof 12 into its normal position when the sound-box is not operatin in connection with the record. In Fig. 9 T have shown the lower end of the arm 10 bent at right angles, as indicated at 15, said right-angle portion having a downwardlyprojecting extension 16, which serves the same purpose as the arm 10 in the form last above described, with theexception that the projection 16 is brought nearer the stylusbar at the front of the sound-box.

In Figs. 10 and 11 I have shown another modification, which is similar in action to that described in Fi s. 1 to 4, inclusive, with the exception that t e arm or guard is made in the shape of a sector 17, which is pivoted in a recess 18 by means of a pin or similar device 19. A bow-spring 20 is attached to the inner end of the sector 17 and bears upon the upper arc-shaped surface 21 of the recess 18. The spring 20 tends to hold the guard or support 17 normally extended from the central portion of the recess 18 but when the same istin contact with the record and the record is caused to revolve the support 17 will be thrown to one side, owing to j the frictional contact with the record, and

will allow the stylus to engage the recordgroove. .In this form of the device the record may be moved in either direction in relation to the sound-box and the effect will be the same, although, if deemed advisable,

a stop may be employed to prevent the support or guard 17 from turning except in one direction.

The action of and the result attained by different forms of my invention as above described are similar, and the essential features thereof may be arranged in other Ways and varied in shape and form without departing {)rom the spirit and scope of my invention;

What I claim, and desire to protect by Letters Patent of the United States, is
