Specification of Letters Patent.

Patented May 11, 1915.

Application filed May 11, 1914. Serial No. 837,671.

. talking machine of either the disk or cyline (ler type in which a casing with a lid is used, and the invention is designed to provide for the winding of the motor of the machine by the moving of the lid.

The machine has a connection between the winding means of the motor and the lid so that when the lid is operated, the winding means is actuated to put the motor under tension to play the succeeding record.

The invent-ion permits the use of a light weight or spring as motive power, as the automatic winding 'of the motor at each operation of the lid necessitates only enough power to play one record.

To more fully perfect the machine I have devised a construction in which the parts are so disposed that the lid must be operated to give access to the record. and must be again operated to uncover the horn, in this way insuring a winding of the motor at the installation of each record.

The invention further provides for an improved talking machine in which the arrangement of the parts allows the base of the machine to be small so that it can be placed on an ordinary stand or table, but at the same time allows a comparatively long sound passage or horn which is desirable to secure clear and loud reproductions from the record.

A still. further object of the invention is to provide a horn which is contained within the casing of the'machine, but which avoids the motor n order to prevent the noise of the motor from being heard during the reproduction by the machine. This is preferably accomplished by forming the sound passage into two channels between its out let end and its reproducer end to form a space in which the motor is placed. This ar angement also permits the inspection of,

It will be further understood in this invention that the motor is in a casing formed by walls of the horn passages, and the cats ing thus formed provides a convenient position of the motorof the talking machine and at thesame time does not interfere in' any way with the transmission of sound through the horn passages.

The invention is illustrated in theaccomf panying drawings, in wliich- Figure 1 is a vertical section through the; 1

of talking machine. of the machine shown in Fig. 1. Fig.3

, center of Fig. 2, illustrating my new form Fig. 2 IS a front view is a side view, partly broken away, sho'wj mg a talking machine with a modified form,

of lid.

In my improved form of talking machined the figures of the drawing embody onetype 'io of machine, but it, will be understood thatjj changescan be madein the details of construction without departing from the scope of the invention.

The machine consists of a casing which can be ornamented or left plain if desired,

and can also be made in a variety of shapes, the general design however being formed as v a. compact cabinet or casing with a record" chamber and horn outlet which are adapted to be closed by a lid or door common to both. In the form illustrated, the casingfl consists of a back 10 and sides 11, the back extending f01'\ *ardly at the top, as at 12,

and terminating at the front, the f1ont be- .5 ing open and adapted to be closed by a suit I able door. A transverse partition l3and a strip 14 form a record chamber 15 at the front I of the machine. supplied with any suitable record-holding The' record chamber. is."

device, the type shown consisting of a turn table 16 on which the, record 17 is placcd, the turntable being mounted on a spindle 18 driven by a suitable motor. spring motor 19 which is fastened to the a bottom 20.

I illustrate a '7 back of the artition 13. The casing-has '1' In the record chamber is arranged there-f producer or sound-box of the machine, the' drawing showing an ordinary sound-box 21 T-shaped tube.

lets which slide in tone arms 24, the tube sliding freely in the tone arms, but being thus free to move when the stylus is moved 1106 fitted close enough to fully transmit the the motor while the machine is operating. sound. The tube and the sound-box are iby the groove in the record. A stop 25 liniits the swing of the tube when the stylus};

is withdrawn from the record. The tube; 23 is freely rotatable in the pipes and can be easily swung to control the placing and removalof the stylus on and from the record. The tone arms 24 are bent backward at their outer portions as at 26 and pass into the partition 13, thus directing the sound vibrations from the reproducer and tube to the rear-of the partition. The walls 27 are so placed as to form two side channels 28, and

which the motor is placed out of the path of the sound and easy of access through a door 31. A rear wall. 32 extending across the channels 28 assists in directing the sound throughthe horn and forms, .with. the walls 27, a well defined pair of sound-channels leading to the big end of the horn.

A lid-is placed on the front of the casing to alternately close the record chamber and the big end of the horn. In the drawing I illustrate a sliding lid 33 moving in suitable ways 34. The lid is proportioned so as to cover the record chzimber orthe horn. This necessitates a sliding of the lid to give access to the record,and then it is necessary to move the lid in order to uncover the horn to let the sound escape. This compulsory movement at the playing of each record insures the confinement of any squeaks or scratches from the needle and the sound from them does not escape. Another feature of the compulsory sliding is that it insures the operation of a winding mechanism when such mechanism is connected to or operated bythe lid. In the form shown I p ace a rack 35 on the back of the lid, the rack meshing with a pinion 36, this in turn operating a gear 37 which is on a shaft with a pulley or sprocket 38 connected by a chain or belt 39 to a winding device 40 which is not shown in detail and can be'the usual ratchet mechanism now commonly employed in this type of machine and well known to those skilled in the art. A suitable handle 41 is placed on the lid 33 for its easy manipulation. I do not wish to be understood as limiting myself to a sliding lid, as other .kinds of movable lids can be employed for alternately closing the record chamber and the horn. T

In the modifications shown inFig. 3 1pmvide the door 33 with an extension 42 in which can be mounted a supplemental lid 43, this supplemental lid being adapted to be opened and left open while the machine is in use, but closed to keep dust from the horn when the machine is not in use. A

suitable stop 44 holds the supplemental lid open. The winding means is so arranged greases down, to tighten the spring in the motor, whereby the resistance of the spring holds the lid up and the weight of the lid assists paniment of the scratching or singiiig of;

the stylus which is sometimes present in machines using a lighter weight reproducer.
