Application led March 10, 1916. S'erial No. 83,375.

To` ZZ fw 71.0111y t may con cern Bc it known that I, LAURENCE S. Home non, a citizen of the United States, and a resident ot' 0klalioma, in the county of Oklahoma and .State ot Oklahoma, have invented an Attachment or improvement in Talking-Machines, ot which the following 1s' a specification.

rllhls invention is an improvementA 1n talking machmes and has particular reference to a machine of the disk type wherein a reproducer carrying arm 1s operated to move conclusion of .the to raise the sound box or reproducer from transversely,across a record. during the' reproduction thereof. I

An object of the invention is to provide a mechanism automatically operated, at the reproduction of a record,

engagement with the record and return the same, together with the tone arm, to its original or starting position, sound box is again lowered and the stylus caused to engage the record groove. To this end, thereis rovided Va tone arm actuated vlatehing mem er which -is thrown to a -releasing position, when the sound box has traversed the record groove, to permit the rotation'of a disk or similar element. This rotation of the' latter member is designed to operate a lever and cause the same to engage a lifting arm which raises the sound box from the record and then, through' the medium of the further movement of Athe lever, swings. the same, together with the tone arm, to its original position with thesound bon lstill elevated. Still further movement of the said lever releases said litting arm and allows the reproducing stylus to be lowered into contact with the record after which the rotary disk is automatically. stopped by engagement with said latching member and the parts are in position for another operation.

Moreoventhe invention has for another object the provision of novel mechanism for `automatically reproducing several records successively wlthoutthe necessity of remov ing and replacing a record after the complereproduction. lin carrying out .this .object the invention' provides a sup- 'fi'n whic lare mounted ille/'- imm-tabl@ a l records iunted inthe path of carin, vas the same is ormai position, and 1s whereupon the n r'superimposed` relation.`

Fig.; Il..

actuated, through suitable ccmnecti'ons, to give the shaft, to which are secured a number of record supporting 1nembers,a partial mechanism 4is arranged so that the record isdropped just previous to the return of thc'sound box to its original position.

It is also proposed to enable the repetition of the reproduction of a record severaltimes,`

and this is accomplishedby advancing'or rotatingeach record a certain distance, so that the Vslots in the lowcrmost record will not register with said members until the desired `number of repetitions have been made.

The inventive idea /involved is capable of receiving a variety of mechanical expressions, 'one of which, :tor the purpose of illustrating the invention, is shown in the accompanying drawings; but it is to be expressly understood that said drawings are merely for the purpose of facilitating the description of the invention as a whole, andy not to define 4the limits thei'eot; reference being had to the appended claims for this purpose.

F ig. 10 is a section on the line 10-10 of Fig. 1.

Figs. 11 and 12 are sections on the lines 11-11 and 12-12 of Figs. 2 and 6, respectively.

One form of the invention, illustrated in the drawings, is so constructed that the same may be readily applied to certain talking machines now commonly used, which include the'usual turn table 15 upon which are supported the different disk records, the swinging tone arm 16, and the sound box or reproducer 17 having the usual stylus 18.

The invention consists .of a shaft 19 having a-suitable connection with the usual motor (not shown) for operating` the machine and said shaft is rotated and held stationary, when desired;` throu hthe medium of any suitable clutch mec nismA also associated therewith but not shown in the drawings. The shaft 19 is mounted in a suitable support 20 and has secured to one end thereof a rotatable disk 21 having a shoulder 22 on its periphery. When-the parts are in the position shown in Fig. 3 a latching mem' ber 23, pivoted at 24 to the support 20, has a shoulder 25 in engagement with the shoulder 22 on the disk 21 and a. small spring 26 i retains said latehing member in this position so as. to'prevent rotation of said disk and consequent rotation. of the shaft 19.

Means are provided for lifting the sound box 17`from engagement with the record at the completion of the reproduction thereof and consist of a sound box lifting device 27 in the form of lever pivoted at 28 to an arm 29 extending from the main portion of the tone arm'16. One end 300i theA lifting device 27 engages the under side of the goose neck of the sound box while the other end is curved as indicated at 31 and adapted to be engaged at the completion of a reproduction by an Vangular piece 32 carried by the upper end of the lever 33. In order to permit of this engagement and consequent actuation of the sound box lifting device 27 the tone arm 16 has secured thereto a contact member 34 which, after the stylus 18 has traversed the record groove, engages or contacts with the latching member 23 and thrusts the same to the posi-tion shown in Fig. 4 whereupon the shoulders 22 and are disengaged and the disk 21 permitted to rotate. It is to be noted that at the beginning of the rotation of said disk the reproducer or sound box lifting device is in engagement with the end ,i

32 of the lever 33, as shown, and remains until the parts assume the position shown in Fig. 8. The disk 2 1-is provided with the laterally extending pin 35 which engages in the slot 36 formed in the lever 33, said lever being also provided with another slot 37 at its lower end into which projects a pin 38 carried by the support 20. As the rotation of the disk 2'1 continues the pin 35 engages the lower end of the slot 36 and causes the end 32 of the lever 33 to describe a predetermined path of movement, as shown in Fig. 7, with the assistance of a cam member 39 adjustable by means of an arm 40' to the dotted line position shown in Fig. 9 when it is desired to reproduce larger records. This cam member 39 includes spaced elements, the upper one adjustable, which provide a slot 41 therebetween and a pin 42 carried by the lever 33 engages under the lowermost element of the cam, as shown in Fig. 7, just after the disk 21 has started to rotate. The lower end of the lever 33 containing the slot 37 is forced downwardly, during this movement, against the tension of a spring 43 until the upper end of said slot 37 is in engagement with the pin 3S whereupon said pin will act as a fulcrum for said lever for a short space of time. Upon reaching the farther end of the lowermost element of the cam 39 the pin 42 will ride over said end and, by reason of the tension of the spring 43 secured to the lower end of the lever 33, said pin will be caused to engage the upper element ofthe cam 39 and be forced into the slot 41 between said elements. Continued rotation of the disk 21 will swing the lever so that the pin V42 will move .to the other end of the slot 41 until disengaged'from the upper element of the cam 39. Up to this time it will be seen that the sound box or reproducer lifting device 27 has'been adjusted'to its lifting posi-tion` as shown in Figs. 5 and 6, and that the same remains in this yposition throughout the movement of the lever 33 and consequent movement of the tone arm 16 to its original or starting position. When the pin 42 disengages from the slot 41, the spring 43 will cause the upper end of the lever 33 to suddenly take an upward vertical course` as clearly shown in Fig. 7, whereupon the lift-- l ing device 27will be lowered and permit the los lBy referring to the tone arm 16 as the same is moving transversely across the record during the reproduction thereof. I i

The invention also contemplates the automatic reproduction of several records 4in succession, and to this end'there is provided a substantially U-shaped frame 44 which is preferably. secured to the chine and overhangs'the turn-table -15 thereof. The horizontal member of the' frame 44 has extending laterally therefrom an arm 45 on which is mounted a reciprocating member 46 having a slot 47 adjacent its.

outer end for receiving therein a pin 48 rcirie outer extremity of the reciprocating member 46 is provided with a depending contact rod 49 which is engaged by a portion of the tone arm 16 when the same is being moved to its original or starting position whereby said member 46 is adjusted tojthe full line position shown in Fig. 1 against tlietension of a spring 50, the limit of salidmovement being assumed whenthe tone arm is in the dotted line position as shown in Fig. 1 just previous to the return thereof tothe original position. The other extremity of the member 46 is provided-with a small extension or pawl 51 which, as lthe'member is being moved as just described, engages one of the teeth of the ratchet wheel 52 which is se cured to the-upperend of a vertical shaft 53 thus giving said shaft approximately onetwelfth of a revolution, as shown in the drawings. I

The shaft 53 is mounted directly over the central post of the turntable upon which the records are mounted and has extending therefrom, intermediate its ends, a'number, preferably three, record supporting arms54, 54 and 54 having small anti-friction rollers 5 5 carried by the extremities thereof, said rollers being adapted to vengage the bottom face of the lowermost of a plurality of superimposed records 56. 'lhe supporting arms are pending spiral extensions 57 the purpose of which is to cause lthe record to rotate as the same is lbeing lowered onto the turntable 15 whereby sa'id record will be rotated with approximately the same speed as the turntable when the same engages thereon, thus preventing undue friction. Moreover, such rotation of-the record 56 as the same is being lowered along theshaft 53 will, by reasonv of the centrifugal action, prevent the same from dropping upon` the turn-table. The horizontal portion of the frame 44 also has .depending a y i 1,312,250

casing of the mapreferably provided with de# withtoo great a force i therefrom a stoppin 58 wh-ich engages in one of a number of openings 59 formed in the records 56 whereby said records are prevvented from turning until the same have dropped below the lower extremity of the pin.

In order to readily permit o'f the records being lowered onto the turn table the same are each provided with radially extending slots or openings ($0, 60', and (30, correspending in number to the number of record supporting arms the same shape as said arms but of slightly larger. proportions so that when the shaft 53 is rot-ated and one ofthe arms is brought into registration with its particular opening. or slot .the record will be lowered.l In the embodiment shown in the drawings provision is made for mounting three records upon the supporting arms and the parts for rotating the shaft 53 are adjusted so ithat said shaft is given one-twelfth of a revolution when actuated thereby. ln order to avoid confusion in the illustration of the j invent-ion, as shown in Fig. 11, the slots for ,only the lowermost and the next superimposed records are. shown, respectively in -dotted and full lines. Referring to Fig. 11

it will be seen that when the shaft 53 is rotated in a clock-wise direction the, supporting arms 54, 54 and 54 will rotate one-twelfth of a revolution, as previously stated, and will then be in registration with the slots G0, 60 and 60', shown in dotted lines which will permit of the record being lowered. The position of the record as just described is also clearly illustratedv n Fig,

and of substantially 12.' Upon the lowering of the lowermost4r record the next superimposed record will be lowered by gravity onto the supporting arms and when theshaftr 53 is next actuated as previously described, the same operation will take place. Should itV be desired to re peat`the mounted upon the turnftable of the machine, the superposed records arefadvanced, by hand', in a clockwise direction, either onetwelfth or two-twelfths of a revolution laccordingto whether or not it is desired to have one or two repetitions. Thus by moving the lowermost` record from the dotted 'line position of the sl0ts,`as shownin Fig. 11,l to the full line position thereof and in turn adjusting` the next superimposed rec ords to one position 1n advance of their original locationsv 1t action of the tone arm and sandbox, as

previously described, will still take place and i the turn-table willthe record already on reproduction of a, record which isr rotated, will not be repeated. Shouldl it bedesired to vreproc duce the record three times, instead of two as just described, the superposed records are advanced another twelfth of a revolution whereupon at the end of the third reproduction the supporting arms will register with the openings in the lowermost record and the same will be lowered onto the turnrelease said revoluble member at the end.
