COIN-OPERATED TALKING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 670,925, dated April 2, 1901.

Application filed June 8, 1900. serial No. 19,570. (No model.)

To all whom, t may concern:

Beitknown that I, CHARLES T. BRADsHAw, 'a citizen of the United States, and a resident lof the cit-yof Philadelphia, State of Pennsyl- Vania, have invented certain new and useful Improvements in Coin-Operated Talking-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain improvements in automatically-operated talking-machines, and particularly to that class commercially known as the gramophone The main object of thisinvention is to provide a machine so constructed as to be thrown in operation for a certain time, subject to the deposit of a suitable coin; and the invention consists in the improved construction of the coin-operating mechanism and the combination and arrangement of various other mechanisms acting in conjunction with the said coin-operated mechanism, such as is herein fullyset forth, and particularly pointed out in the claims made hereto.

In the accompanying drawings,which form a part of this specilicaton, audin which similarletters of reference are used to indicate similar parts, Figure lis a plan view of a machine constructed in accordance with myinvention, the inclosing casing being shown in section. Fig. 2 is a side elevation of the same with the coin chute and holding mechanism removed, also the shifting lever and its supportingstandard beingr removed and the inclosing casing shown in section. Fig. 3 is a crosssectional View taken about on the line 3 of Fig. l. Fig. et is a cross-sectional view taken about on the line a a of Fig. l. Fig. 5 is an enlarged detail section taken through the coin holder and chute, illustrating the pushlever and also thewlever for turning the reproducer to normal position. Fig. 6 is a detail View of the coin-chute, and Fig. 7 is a detail perspective of the coin-holder.

The outer casing of the machine comprises a suitable cabinet', as A, having au upper compartment a, in which are located the gramophone and its operating mechanism. The top of the section d is formed with a hinged lid a', so that access may be had tothe interior mechanism, and the front wall a2 of this compartment is also hinged at its bottom, as

at CL3, so that it may be swung outwardly, so as to give easy access to the tu rn-table when it is desired to change the record. i The coinchute and coin-holder are supported on this hinged wall o?, and consequently move with the same when the said wall is let down. i The lower portion of the cabinet A is provided with a cash-drawer b to receive vthe coins as they pass through the coin-'chute and also provides roomfor the batteries which run the motor for driving the turn-table.

B designates the motor, which may berof any of the well-known constructions and is connected by the usual wiring with the source of the electrical supply. I

The turn-table C is rigidly mountedfon a spindle c, which is supported in a bearing-post c', secured to the base A, the said base being supported on the partition B, which separates the upper and lower sections of the cabinet.V

On the turn-table spindle directly abovethe y bearing-post c is rigidly secured a gear c2, which meshes with a spiral gear c3, carried'by the forwardly-extending portion of the motorshaft b. .This construction of gearing the` i turn-table to the motor gives a unifuorm speed, l

the said table acting as a governor". The record C may be secured to the turn-tablcin any well-known manner.

The reproducer-arm D is universally mounted in a post d, carried by the base A', and on the forward end of this arm D is secured the e, both of which may be of the usual construcof the arm d extends some distance beyond the end of the reproducer-arm and is twisted, as illustrated in Figs. land 2, so as topresent a surface to contact with the lug orpinf, carried by the rear wall of the casing,'and thus limit the movement of the reproducer-arm in the one direction. This arm d can be adjusted by means of its slot d2 and setscrew cl3, so as to regulate the movement of the reproducer-arm and prevent the stylus-point from moving beyond the last line of the record.

G designates the coin-chute, which is secured by means of brackets g to the hingesection a2 of the casing. This chute Gis pref- IOO 8s sound-box E, carrying a stylus-point or needle connected .by the cross-bar h', thus forming a,

slot in the upper portion of the plate h of a size large enough toad mit the coin to be used. In fronthof theV coin-helder H is located a vhollow sleeve I, the forward evudvof which is secured in au aperture formed in thehin'ge'd section@2 of theeasing and the rear end of whichbears against the said coin-holderH.

A plungerJis itt'ed intofthe sleeve I', having A itsinuer portionreduced to 'formv the stemj, which extends through'an' aperture formed in the end ofy said'sleeve and is screw-threaded" int'oav` boss formed on 'the ki-earlaceof they pla-tehof ,thecoin-holder, and a pinj passes .through this boss andV through the stern j, so

- asl topreventthe.,plunger: .l from beingvremoved from the ou'tsideofthe casing.4 vAround the stem j, inside of th'esleeve I', is a coiled spring whichfisy compressedvv when the plungerJiis pushedin and serves to return thev said plunger to normal position aft-crit is re-- leased. On the lower side ofv the sleeve I are s ecured two pinsor thini'ods la, extending rearwardly on each side lof saidsleeve'v 'and passing thrbugh the sleeves le', formed on the coinV` holder H, and through aperturesk2, as inost clearly illustrated in Fig`.jl7' of the drawings.

These pins serve as rests, against which 'the lowerpedge of the coin bearsmwhen"it'enters thecoin-holder. The said pins areiof such a distance apart as to allw'sinall coins to pass between them and drop down linto, the receiving-chute K without operating the ina-A chine. "f

To one side of the coin holder and chute l provide a post'L, whichha'sl locatedfzthereon a shortv distance`-above the coin-holder a pivoted stud Z, to which is rigidly secured a loent lever M, the lower end of said lever extend-` ing down to' about'the'lcenter ofthe coinholder, where it is. bentl outwardly and forwardly to form the arui'm, which is located directly in front of the coin-holder H, as illustrated in Fig.- 5 of the'drawigs. `A recess h2 is formed in the plate h of the coin-holder directly opposite the end of the arm on, so that when the push-lever J is operated to movev the coin-holder inwardly the arm m will enter the aperture h2. The upper end of the arm M is bent inwardly, Aas illustrated in Figs. 3 and 5in the drawings, and restsl against the upper surface of the reproducerarm D.' The'upper surfaceofihe portion fm of the arm Miszserrated, as illustrated.;

On the top of Lthe reproducer-arrn D, to one side of the arm m', I secure an L-sha ed arm N, having a slot n, through which passesl a` set-screw M", so that the said arm` may be adjusted back and forward for the purpose hereinafter described. The member N' of the L- vshaped arm N is a slight distance above the arm m of the lever M, and around this memberis apieceof rubber tubing or other similar, material for deadening the sound as the said lever M comes in contact with the bar N for the. purpose of shifting the reproducerarrn, as hereinafter described.

Secured to the top of the post L is au arm O, extending upwardly and then curving inwardly, as illustrated in Figs. 3 and 5 of the drawings, thepurpose of this arm heilig to act as a stop, against which the member N of the bar N strikes when the reprod neer-arm is returned to its initial position.

To the'right of the coin-holding mechanism zis a hollow post or standard P, the lower end'lof which passes through auaperture in the baseer. and is secured therein vloysuit- On the outer end of the plate p is 'The inner end of the screw q is swiveledI in a vertical, lug c arried by the contact-plate 29?, and the outer'lend of said screw is providedfw'ith ainilledhead forroperating the sarneh One of the supply-wires from the battery passes up through "the post P and electrically connects theadjustable contactplate p2.

to return thereproducenarm to its initial postion. In operation the lcoin is deposited in the slot g2 into the coin-chute G, which guides itr 'to the coin-holderv H, the projecting pinsk lserving to support the coin and prevent its dropping through said holder to the receiving-chute. `The push-lever J is then operfated,vwhich action carries the coin-holder forwardandthe coin cornes in contact with the arm in of thelever M and swings the same upon its pivot Z and causes its `arm m to bear 'against the larm N of the bar N, which is secured toy the reprodueer-arm and liftthe same v"and move it `forward until `the arrn N strikesagainst the 'guard O, carried by the J post L. This action brings the stylus-point e in engagementwith thefirstline of the record. Themo'vement of this arm and the reproducer can be adjusted to suit diierent widths of recordsby adjustingthe arm N `by uleansof the set-screw n andthe slot.

As soon as the lever M has been tilted by the operation just described and the reproducerarm is being returned to its initial position the contact-sprin g r will engage the electrically-connected portion of the contactplate p2, which immediately starts the motor, so that by the time the stylus-point is brought into contact with the rstline of the record the turn-table will have reached its normal rate of speed and the reproduction will beV commenced. vA controller, such as t, which may be of the usual construction, may be employed for regulating the amount of cur rent, and thereby regulating the speed of the motor. As soon the stylus-point reaches the end of the record-groove the contact-spring fr" will leave the electrioally-connected port-ion of the contactplate p2, thus breaking the circuit and stopping the motor. Just as the last line of the record is reached the arm d', which is adjustably secured to the rear end of the reproducer-arm D, will strike against the stop-piu f, and thereby prevent the said reproducer-arm from carrying the stylus-point beyond the last line of the reeord. This arm CZ is adjustable, so as to accom modate records of different Widths. rlhe contact-plate p2 is also adjustable by means of the feed-screw q, which is threaded in the boss'p, carried by the supporting-plate p, the said screw q being swiveled in the lug, which carries the movable contact p2. The starting and stopping of the motor are thus regulated by the adjustment of the contactplate p2, so that the feed of the reproducerarin can be regulated to suit the length of the record. Vhen the plunger J is pushed in after the insertion of a coin and the lever M is operated as heretofore described, the coin will drop out of the holder into the receivingchute K, as the pins k are stationary, and the coin-holder on its inward movement moves away from the said pins, thereby releasing the coin and allowing it to drop in the chtite to the cash -drawer. The coil-spring j, located around the plunger-stein inside of the sleeve I, returns said plunger to normal position as soon as the operator releases it.

The coin-chute Gis preferably constructed, as illustrated in Fig. 6 ol' the drawings, so as to prevent the insertion of wires or light pieces of cardboard, by means of which the machine might be fraudulently operated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
