REPRODUCER FOR TALKING-MACHINES.

Specification of Letters Patent.

Patented m 1, 1919.

Application filed April 18, 1917. seriallto. 162,877.

To all whom it may concern:

Be it known that I, ALBERT A. HUsEBY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Reprodu'cers for Talking-Machines, of which the following is a specification.

This inventioh relates to improvements 1n reproducers for talking machines, and has reference more particularly to that type of reproducers commonly known as universal reproducers or sound-boxes, which are adapted to play records of both the vertically and laterally cut types. Such universalreproducers are themselves distinguished by typical variations of structure and manner of use. Most of them involve a change of an gular position of the sound-box relatively to the tone arm when changing from one type of re'cordto the other. Of these lattensome employ a single stylus-socket with a single stylus therein, others a single stylus socket with interchangeable styli, others a pair of stylus sockets with a single stylus that may be used in either socket, and still others two stylus sockets with styli individual to each socket. Those reproducers which do not involve a change of angular position of the sound-box relatively to the tone arm when changing from one type of record to the other employ a pair of stylus sockets with 1 s'tyli individual to each socket; but the socket for the stylus that plays the vertically cut record isformed in an attachment memher that is detachably secured in the other socket. I I

The reproducer of my present invention belongs to that class which does not require any angular change of positionof the soundbox, but employs two permanently attached socket members or stylus holders, so that all that is required to adapt the reproducer to play eithertype of record is to insert the appropriate stylus in the proper stylus holder and then lower the reproducer into playing engagement with the gnoove of the record disk.

Furthermore, in playing diflerent types and makes of records it is desirable, in order to secure the best results, to weight the sound-boxes difl'erently on the records. For instance, in playing a Pathe record, the grooves of which are comparatively round and shallowywitha Paths stylus it is de- 552% to place more weight on the'sound" with a sharp-pointed Edison needle; whereas the playing of a Victor or Columbia rec- 6rd calls for a weighting of the sound-box intermediate the weights preferably h s d in playing the Pathe and the Ed i sontr e ords respectively. The principal feature of/ my present invention, therefore, resides in the combination with the usual swiveled free end section of the tone arm, of an adjustable weight which may be set to either side of the axis of the swiveled section of the tonearm so as to increase or diminish the gravity effect of the sound-box and swiveled tonearm. section on the record.

y invention, its mode of operation, and the advantages inhering therein. will all fbe readily understood by those familiar with this art .from a consideration of the followin g description taken in connection with the bodiments of the invention, and in which" Figure 1 is an elevation,'broken out, of

the usual swiveled extension of the tone-arm and the sound-box connected to the latter, showing my present improvements applied thereto;

Fig. 2 is a similar view, partly in vertical section, as seen from the right of Fig. 1;' Fig. 3 is a. face elevation of the sound-box, illustrating a modification; Fig. 4 is a view similar to Fig. 3 illustrating another modification.

Referring to the drawing, :5 designates the tone-arm in which is swiveled the usual downwardly and laterally offset tone-arm extension 6, to the free end of which latter is coupled the sound box designated as an entirety by-T. On the lower side of the soundbox are-a pair of forwardly extending lugs 8 carrying pointed pintles 9 on and between socket-piece 13 disposed at a right angle to r the axis of the fulcrum-bar and having a transverse socket 14- adapted to receive a needle o'rstylus suitable for playing'records' {of the--.-.ve1tically cut type. Both of the socket-pieces Hand 13 are Permanently and permanent elements of v the sound-box structure. Rigidly connected to, the fulcrum bar is a stylus arm, theupperend =0f=\\'l rieh-1s.
