INVENTOR HENRY BERMAN ATTORNEY HENRY BERMAN, or ossirntnci, NEW YORK, assrenoa or. one-HALF TO EMIL ERIK,

or ossm ne, NEW YORK.

SOUND Box.

Application filed my 2,

To all whom it may concern. I Be it known that I, HENRY BERMAN a citizen of the United States, residing at '&)s sining, in the county of West'chester and State of New York, have invented certain new and useful Improvements in Sound Boxes, of which the following is a: speciflca tioil. I i

This invention relates tophono'graphs and particularly relates to a Construction thereof whereby the horn and reproducer elements thereof are materially're'duced in number of parts and cost of production without sacrificing any of their effectiveness.

The invention consists essentially of a collapsible sounding board or shell in lieu of a horn and a removable reproducer co-acting therewith, whereby when the sounding board is collapsed, the reproducer and its support can also be removed leaving the phonograph with a top having no projections therefrom.

' dotted lines.

I have shown one embodiment of my invention which is the best of which I am at present informed but this embodiment is used in an illustrative sense and not a limiting one for the invention is capable of many different embodiments.

I have illustrated one embodiment of the invention in the accompanying drawings in which Figure 1 is a side elevation of the device;

Figure 2 is a front elevation;

Figure 3 is a vertical section thereof;

Figures 4, 5 and 6 are detail views.

The phonograph is of the usual box con struction having a top 11, front 12, back 13 and

sides

14 and 15. Within the box is the usual motor (not shown) and turning table 16 upon which the disc is adapted to be placed. The top 11 is slotted at 17 and because of this slot which weakens the top, it is provided with additional supports 18 and 19.

A collapsible sounding board or shell is pivoted on a shaft or shafts 20 extending into the box .from its

sides

14 and 15 and the shell consists of a plurality of

telescopic parts

21 and 22. These parts are adapted to be swung about their pivot 20 either to be extended above the box as shown in full lines in Fig. 1 or down within the box as shown in That the shell parts co-act properly with each other the part 21 has a flange 23 on its lower edge adapted to engage with the box at the edge of the slot 17 to Specification of Letters Patent. Patented July 25, 1922,

1921, serial No. 482,121.

limit upward movement of the shell part and the partlias another'flange 24 which is upment limits the'extension or outward movement of the shell part 22 with respect to the part 21. 1 preferably provide a rubber gasket 26 between the

flanges

24 and 26 to cleade'n any noise or to prevent vibration. The front edge of the shell part 22 is hooded as at 27 so that when in closed position, the hood 27 covers the slot 17 (see dotted "line position Fig. 1).

That the pivotal movement of the shell may be easily brought about, the shaft 20 is flattened and securedthereon are collars 30 having a bent up flange 31 for engagement with the edge of the shell part 22 so that when the shaft is rotated, the flange 31 engages the shell part and it is rotated along with the shaft 20. Continued pivotal movement of the shaft and shell part 22 causes the flange 25 of the shell part 22 to engage flange 24 on shell part 21 whereby shell part 21 is also pivotally moved until extended position is reached.

That the shell parts mav be locked in extended position, the part of the shaft 20 extending from the box is encircled by a clutch member 32 having a handle 33 adapted to be pressed into engagement with a socket member 34 on the side of the box by means of a spring 35 braced from a knob 36 on the shaft 20. The shaft 20 is rotated by means of the knob 36 until extended position of the shell parts is reached, whereupon the clutch member 32 slips into the socket 34 by means of the spring pressure thereon and the parts are locked in this extended position. To unlock the parts, it is only necessary to rotate the clutch, by means of the handle 33, out of its socket, and immediately the shaft 20 and its shell parts rotate or fall by gravity into withdrawn position.

The reproducer is supported to be slid along by the playing of the record on an offset arm 37 removably held in position by entering cups or socket pieces 38 and 39 in the top 11 of the phonograph. It is merely lifted out of these sockets to be removed.

The reproducer is slidably and removably held upon the arm 37 by means of an arm 40 and spring clip 41-1. The arm 40 terminates in a ring 42 in which the reproducer is fricriphery pressed into a doubled flange-l tterminating in a rolled edge 45 rolled over a wire 46. The doubled flange 4L4 fits snugly into the ring 42 of the arm 40. The-needle arm 47 13 secured to the diaphragm at 48 and the arm terminates between the downwardly

bent ends

49 and 50 of the wire 46. The

needle Si is held between the

ends

49 and 50 of the wire 46 and clamped there by means of the handled clamping cam 52. An amplifier 53 is forced or seated in the doubled flange 44- and adds additional tension on the diaphragm Tliis tension can be varied by using amplifiers of different sizes or diameters. Also the amplifier is seated on a gasket 54.

Thus it will be seen that I have devised a hornless phonograph whose reproducer and sounding board canbe completely removed when not in use so it can present a flat top without obstructions thereon and having a reprodurer that is extremely cheap to manufacture with a minimum of parts.

What I claim is:

1. In combination in a phonograph, a re- Jproducer having a metallic diaphragm, a flange integral with said diaphragm, and a wire enclosed by said flange, said wire having outwardly bent ends.

2. 'lheapparatus of claim 1 with means for maintaining a needle between the ends of said wire.

3. The apparatus of claim 1 with clamping cam means for maintaining a needle between the ends of said Wire.

e 4, The apparatus of claim 1 with the addition of a needle 2. band encircling the ends of'the 'wire and clamping means supporting from said band for clamping the ends of the wire together to hold said needle therebetween. i t

In testimony whereof I afiix my signature.
