Specification of Letters Patent.

Application filed July 31, 1915. Serial No. 42,951.

To all whom it may concern:

Be it known that I, RICHARD JAMEs FRET- TIE, a citizen of the United States, residing at Jamaica, in the county. of Queens and State of New York, have invented certain new and useful Improvements in Sound- Boxes, of which thefollowing is a specification.

My present invention relates to improvements in sound-boxes and comprises improvements whereby the sound-box is adapted to be converted to play either lateral or vertical wave records. The features and advantages of' my improvements will be apparent to those skilled in the art from an understanding of the following description in connection with the drawings.

lln the latter Figure 1 is a face-view of a sound-box illustrating one form or embodiment of my improvements shown as if playing a lateral-wave disk-record; Fig. 2 is a partial edge view of the sound-box in Fig. 1; Fig. 3 is similar to Fig. 2 except that it shows myfdevice adjusted as if to play a vertical wave disk record;. Fig. 4 is an en-' larged ve oical section partly in elevation on the line 44 in Fig. 2 looking in the direction of the arrows; Fig. 5 is a modificati'on, the View. being otherwise similar to Fig.

.4; and Fig. 6 is a side view of,one of the parts in F1g. 5.

I will now describe the specific devices of the drawings: 1 is the casing, of the soundbox and 2 the diaphragm. The stylus bar comprises an upper part 3 and a lower part 4, said parts being pivoted to each other, so that the lower part can be adjusted either to extend in continuation of the upper part as in Figs. 1 and 2 for playing lateral wave records, or to extend transversely to the up per part as in Fig. 3 to play vertical wave records.

One end of the part 3 is attached to the diaphragm whereas the other end has transverse oppositely directed cylindrical extensions or trunnions 3, in whose ends are formed suitable centers or bearings for the points of the pivot-screws 5 which are tapped into and extend through the stationary lugs 6 on the casing 1 of the sound-box. The end 7 of each screw may be slotted, to enable said screws to be adjusted by a screw driver in the lugs 6 to form ivotal bearings for the stylus bar to oscillate upon; .see Fig. 2.

jacent the space between the lugs, both of them are bored so as to receive the trunnions 3 through them whereby the lower part 4 of the stylus bar can 'be pivoted as aforesaid into and out of the positions shown in Figs. 2 and 3. When the part 4 has been adjusted into the-desired position,

' the screw 8 is tightened with the result that the lugs 4 and 4' are caused to clamp against the larger-portion 3 of the stylus bar from which the trunnions 3 project, the net result being that said lower and upper parts of the stylus bar are now rigidly united and will act as one bar or lever in the playing of the records, the pivoting of the entirebar being on the points of the pivot screws 5.

The lower part 4 has a longitudinal socket in its free end guarded by set-screw 9 to receive and hold a needle or othersuitable stylus 10 adapted to play lateral wave records.

On the other hand, 11 is a stylus adapted to play vertical wave records,.ii-, being located in a transversely extending socket formed in the back of the lower stylus-bar part 4,}said socket being guarded by a set-. screw 19;.

In the. enlarged view Fig. 4, the socket for the lateral-wave stylus is designated 13 and that for the vertical wave stylus is designated 14. It will be seen that they are transverse to each other but not in the same plane, so that their socket endscan cross each other and thereby provide ample seats for the styli in the part 4 without unduly enlarging or thickenmg it.

Figs. 5 and 6 show a modification wherein the thumb or set-screw 8 is replaced byan ordinary screw 88 which permanently secures the parts 44" and 44 together. The

part 44" is the same as the part 4". in the preceding figures except that it carries a longitudinally yielding detent pin 44 in-f; tended to spring into one or the other of the What I claim is 1. A sound-box, provided with a stylusbar having a part furnished with two separate stylus sockets, one for lateral wave records and the other for vertical wave records; said part being adjustable relatively to the sound-box to bring a stylus in either socket into position for cooperation with a record suitable to it.

'2. A sound-box, provided with a stylusbar having an end-part furnished with two separate stylus sockets, one for lateral wave records and the other for vertical wave records; said end-part being pivotable relatively to the sound-box to bring a'stylus in either socketinto position for cooperation with a record suitable to it.

3. A sound-box, provided with a stylusbar having an end-part furnished with two separate stylus sockets, one for lateral wave records and the other for vertical wave records; said end-part being pivotable relatively to the sound-box to bring a stylus in either socket into position for cooperation with a record suitable to it; and releasable locking means for securing said end-part rigid-1y to the main part of the stylus-bar inits different pivotal positions.

4. A sound-box comprising a stylus-bar whose lower part carries two styli for lateral and vertical wave records respectively, said lower part being pivotable relatively to theupper part of said stylus-bar into different playing positions suitable for playing the respective kinds of records with the respective styli adapted thereto, the stylus-bar beingpivotally supported on the sound-box, the pivotal axis of saidsupport coinciding with the axis of the, pivotal connection between the lower and upper parts of said bar.

5. A sound-box comprising a casing, a diaphragm, and a stylus bar pivotally supported on the casing and comprising parts which are pivotal relatively to each other, the pivotal axis of said parts on each other and of said upper part, and means, on said lower part for holding a lateral wave record stylus projecting in continuation of the free-end of said lower part, and for holding a vertical-wave record stylus projecting transversely from the back of said lower part.

7 A sound-box comprising a casing, a diaphragm, and a stylus bar pivotally supported on the casing and comprising parts which are pivotal relatively to each other, one of said parts being connected to the diaphragm, and the other being the stylus bearing part, said last named part having two pivotal positions of adjustment for playing respectively lateral and vertical wave records without changing the position of the box, and two styli positioned on said part to be respectively brought into play by said pivotal adjustment of said part.

8. A sound-box comprising a casing, a diaphragm, and a stylus bar pivotally supported on the casing and comprising parts which are pivotal relatively to each other, one of said parts being connected to the diaphragm,

and the other being the stylus bearing part, said last named part having two pivotal positions of adjustment for playing respectively lateral and vertical wave records without changing the position of the box, and two styli positioned on said part to be respectively brought into plav bv said pivotal adjustment of said part; and locking means for securing rigidly together the two parts of the stylus-bar in their said different positions of relative pivotal adjustment.

9. A sound-box, provided with a stylusbar having an end-part furnished with two separate stylus holders occupying a permanent position relative to each other, one for lateral wave records and the other for vertical wave records; said end-part being adjustable relatively to the main part of the stylus-bar to bring either holder into playing position.

10. A sound-box provided with a stylus bar having an end-part furnished with two separate stylus sockets permanently disposed in angular relation to each other, one for lateral wave records and the other for vertical wave records; said lower part being adjustable relatively to the main part of the stylusbar to bring a stylus in either socket into position for cooperation with a record suitable to it.

In testimony whereof, I have signed my name to this specification, this 28 day of July, 1915.

RICHARD JAMES PRETTIE.
