Be it known that I EINAR LESCHBRANDT, a

' vented certain new and useful Improvements in Talking-Machines, of which the following is a specification. M invention relates to improvements in talklngfmachines; and the obj ect of my invention is to furnish an improvement in coinoperated multiplex talking machines, as more fully set forth hereinafter.

In thel accompanyingdrawings, forming part of this speciiication, and in whichsimilar y characters oi reference indicate similar parts throughout the several views, Figure 1 is a side elevation, partl in central sectional ele-l vation, of a multip ex talking-machine embodyin 'my improvements ;'Fig. 2, a plan ol" Fig. '1; iig. 3, a section of Fig. 1 on line 3 3;

Fig. 4, a section of the cup on line 4 4, Fig.

1; Fig. 5, a section of Fig. 2 von line 5 5; Fig. 6,

a section of Fig. 1 on line 6 6; Fig. 7, an eX- panded view or development of the cylinder y'.

a is an upper, and() a lower, plate which Jform part of the frame of the machine. These plates'are stationary and are'carried in any suitable manner. c designtaes spindles, in the present case ten, which are arranged concentrically around the central shaft At their up er ends the spindles carry each a record e an at their lower ends each a gear-wheel f.

The spindles c are supported in suitable bean in sin the plates aI b.

he 'central shaft d is surrounded for part of its length by a sleeve g, the up erend .of

this sleeve carrying an arm h, whic carricsa sound-boX i, which may be of usual construction. The lower end of the sleeve is attached open at its lower end. Carried by the upper end of cup 7 is a pivoted arm 7c, one side of which is grooved and threaded, so as to lorinv o is carried by the inner end of an. arm p,

which is pivoted at g to the top of cup y'.

r 1s a plate fast to shaft d and so located that when the cup j is in its lowest position it lower end of cup y', adapted tov engage a l standard u.

c designates pins projecting out from the sides of cup y', adapted to engage a coin to arrest a rotary movement of said cup at a particular point. p

There are as many stops tand as many pins e as there are records carried by themachine, and these stops and pins are so placed upon the cup that they each correspond to one ofthe records-that is, one stop and one pin each represents lone particular record.

7 is al coin-chute which is provided with as many coinassages 8 as there are records carried by t 1e machine.

- its 9 is an arm of a' bell-crank lever which eX- tends across all of the coin-passages 8. 10 is the other arm of this lever, which normally is adapted to engage and hold in a raised posi-,

tion a rod 1 1, which is adapted when lowered to close or join the contact-points 12 13 on a line-wire to energize a motor 14, which drives a friction-wheel 15, which drives a frictionwheel 1 6, which is fast to and drives the shaft d.

vNormally the entire machine is at resty and the rod 11 is lraised and no current is passing p from point 13 to point 12. If now a coin be dro ped into one ofthe coin-chutes,it will on dbscent engage' the arm 9 ofthe bell-crank, lowerin this arm and arm 10, so that the rod 11 Will e dropped, connecting the points 13 .12 and permitting a current to pass to start the motor 14, which through wheels 15 16 will drive shaft d. In the meantime the coin will have run down its passage and will have engaged the side of the cup j, as shown in l Fic'. 1.

lhe motor 14 having been started, the shaft d commences to revolve and carries around with it the cup -y' until the pin c, that soon as the pin engages the coin the revolution of the cup j ceases, but the shaft d continues to revolve, carrying around with it the plate r, the stop s, which will presently engage the trigger Im, which will move the nut- IIO forming arm 7c into engagement with the v Y* threads on shaft d. -'Assoon as this engagement takes place the :cup y', bein held from turning, commences to rise, an presently and before the pin c leaves the com 29 the stopt, which corresponds to the pin c and to one particular record, will engage the standard u, which will prevent a rotary movement of the cup j so long as the stlop tis in contact with it.

When the rotary` movement of the cup j is arrested b the in v and coin 29, the soundproducer c will e in position to engage the particular record e corresponding tothe passage 8 in which the coin has been placed, land the vertical movement of the cup j will,`

. through sleeve g, cause the reproducer to be movedlaterally of the record.

' As the cup j is revolved it carries aroundy with it the arm 19 of the sleeve 18, the outer end of this arm engaging aslot 20, formed vertically on the insidev of the cup. This arm and sleeve in turning carry around with them the arm 21 also carried by the sleeve.l

On 'the arm 21 is a gear-wheel 22, which meshes with and is driven by the gear-wheel` 17, fast on shaft d. The arm 21 is directly .under the arm h, which carries the soundproducer t, and hence when the cup y' is stopped rotating by the pin 'U and the coin the gear-wheel 22 is in engagement with the gear-wheel f, that is upon the spindle c, that carries the record that the sound-reproducer this occurs, the stop being released, the cup `will revolve with the shaft until presently the outer end of arm p will strike a stop 23, carried'by top plate a. This will cause the inner end of arm p to move outward, tripping trigger m and at the same time moving the arm or nut k out of contact, with the screw on shaft d. There being nothing now to support the cup y', it will fall by gravity, the plate r forming an air-cushion to prevent a too rapid fall to its lowest position. On its way down the cup will engage the inner end of a lever 24, which is pivoted at 25, and the outer end of this lever, which engages a button 26 on rod 11, will raise this rod, breaking the electrical connection at 12 13 and stopping the motor.

When the rod 11 is raised, ythe arm 10 of the bell-crank lever will bemoved by a'spring 27 under the top of the rod, which will bethus held in its raised position until the passage 'of a coin, which will dro the rod 11,'.as before described, causing its ower end to close the which are adapted to engage pins 31, carried v by the spindles'c, in order to drive the s indles when the gears f are constantly drlven by the gear 22. l

In order to be self-adjusting, the sound-rei I roducer i is not ri idly secured to the arm h, but is loosely hel by this arm to the arm which carries a spring 32, upon which the reproducer i rests.

The coin-o eratedmeans for operating the electric switc which controls the movements of the motor whichvdrives the central shaft,- the record carrying spindles, &c., is not claimed herein. separate application for'patent.

It will form the subj'ect'of-a.

Having thus described my'invention, I l

claim as new and desire to secure by Letters Patent- 1. In a talking-machine, in combination, a multiplicity of record-sup orts placed concentrically around a centra shaft, said shaft, a sound-reproducer guided by and capablev of a movement of rotation around and a 1ongi tudinal movement along said shaft, means for bringing said sound-reproducer into coperative relation with any predetermined one of the records carried by said record-sup ports, means for rotating said shaft, means actuated by said shaft for advancing said sound-reproducer longitudinally of said record-support, and means for rotating said record-support upon its longitudinal axis.
