Specification of Letters Retent. Patented J une 28, 1910. Application led. lay 1B, 19,07.. Serial No. 374,013.'

To all inkom 'it may concern:

Be it known, that I, HYMAN E. MARKLE,

citizen -of the United States, residing at' Nashville, in the county of Davidson and State of Tennessee, haveV invented certain new and useful Improvements in Multiplex Graphophones, of'which the following is a specification.

This invention is an improvement on the machine shown in my application iled August 27, 1906, Serial Number 332,224.

The object of my present invention is to simplify and improve the mechanism shown in my former application; a further object ot .my invention is to@v provide a machine of this character wherein the bringing of the successive records into playing position does not materially increase. the work on the motor and consequently I am enabled to use f a-motor, spring or electric, of the size that would ordinarily'be used in a singlel record -maehine; and with these and minor' objects inlview my invention consists in the parts andeombination of parts aswill be hereinafter more fully set out. f A In. the drawin Figure 1 is a front elevatiou of a multiplex graphophone embodying my invention; Fig. 2 is a top plan view of the same; Fig. 3 is a side elevation; Fig. 4 is a 'detail elevation, partsbeing in section; Fig.`5 is edetail elevation of part of the carriage returning mechanism; Eig. 6 is a detail viewof a slight modification ofthe magazinejwhcel; Fig'. 7 is a detail view of a modiiication of part of the .drivingmech-l anism; Eig. 8 is a detailv view of the carriage'elevating pawl. e

l represents 'a suitablebaseupon which standards -2 are secured.. A frame is mounted uponthe top'of said standards and` secured thereto by. means of ethe bolts or screws' 4.' .One of the side'mexnbers of the frame is 4depressed at. itsv center as at 5 which. permits of the ready reriioyalI of a cyl-l inder record from the magazine l wheel'.

Suitableibearings 6 are hung lfrom the frame'- 3 in which the magazine wheel is jour. naled. The magazine wheel is of.--spi`dej construction,- the spokes on one side c )f"tl'l`e wheel having hinged members 8"which:a'1"e"-V kept in locked position by means of the 10is the carriage rod and 11 the ifeed screw mounted inthe frame?) toward the rear of the machine.

12 is the return or repeating screw mounte near the front of themachine. I

`vd3 is 'a gear casing in which is'journaled a suitable gear'train. v.

14 is the bandorpower wheel connected by means of a shaft 15 to the gear train.

1 6 is the reproducing carriage having a suitable slide 17 mounted upon the rod 10. 18 are feed nuts adapted to engage the feed screw 11. These nutslare mounted upon spring rods or stems 19, which in turn are;

mounted upon the slide 17 and secured thereto by means of the screws 20.

421 is a rod or bar secured near the front of the machine adapted to support the front end of thev reprodueer carriage -16. This bar or rod is provided with an elongated slot 22 to be hereinafter referred to. The -carriage 16 is provided at its front end with lugs 23 and 24 between which is pivoted an arm 25, said arm depending from the carriage and provided with a shoulder 26.

This arm is provided with a pin 27 adapted to contact' with the pin 28 1n theA lug 23, whereby the arm .is'prevented from falling back toward the center of the machine, thusinshring the arm at all times dependingfrom the .front of the carriage.

29 `is a double oam.mounted upon a earriage by means ofthe screw '30, said double andy'32. This double cam, when in the positions shown rin Figs. 4 and 5, permits the' "front of the carriage to rest directly upon the bar or' rod 21. If for any reason, such as transferring records, it is desirable toraise the front of the carriage, the double cam is swu-ng'up'on its pivot whereby one of the cam faces 1s brought into engagement with the rod 21, thereby eleva-ting the front vof the carriage. 'Ifthe carriage is raised without the-aid of this cam lthel arm 25 has' 4a tendency to swing inward until its shoulfder 26 rests upon the top of the bar 21.. When the cam 29 is used the pin 27 of the 85' vcam being provided with operating pins 3.1

',slot 3G.

arm is engaged by one of the cam faces, l whereby it is prevented from engaging the f rod 21.

is a tootlnbar depending from the front of the carriage and provided with the tooth 34, which is adapted to engage, under certain conditions, the return or repeating' screw l2. v

is an arm extending from one Side of the front of the carriage over the bar 21, said arm being provided with an elongated 37 is a llatwhook secured upon the arm 35 byV means of Vthe set screw 38 which passes through the elongated slot 3G. This hook is provided with lugs 39 betweenA which is pivoted a stop40. By ineans of the stop l am enabled to limit the movement of the carriage by reason of the fact that it is ad-A justably mounted through the 4medium of the flat hook 37 and the slot 3G. The carriage is provided with a loose-ly hung pawl 41 having an elongated slot 42 in which a screw 43 is secured tov limit the side moveinent oit said pawl. The pawl in Fig. S is normally pressed from the carriage toward one side by means of the flat spring 44.

45 is a cam mounted upon the right hand end of a repeating or Areturn screw l2. Any suitable means may be employed to lock said cam at any desired point on the screw 12 according to the length of the record to be reproduced.

ln the operation of the machine the carriage is fed toward the right and as the end ofthe record is approached the pawl v41 contacts with the cam 45, but, by reason of the flat spring 44 and the slot 42, said pawl is adapted to give until the limit of compression of the spring 44 isreached, when, the friction between the two parts is sufficient to enable the pawl to climb the eccentric when the lowest point of the: eccentric is reach-cd, vwhereupon the energy stored up-in spring 44 causes the pawl 41 to slide upon, the periphery of the-eccentric. l y reason of this lateral movement ol the paw] it is adapted. to have a wide point of contact with the ccentric, whereby it is In'ev'imted ,11 and the tooth 34 is in engagement t'rmn :medentajlly slipping ofi'I of the eccentric. ,Ys soon as the pawl is in engagement with` the highest point of the eccentric or cam, the Vfront. of the carriage is elevated and the arm '2:3 permitted, by gravity, to fall against the bar 21, whereupon the shoulder 2li rests upon the top of the bar 21. f ln this position of the carriage the .tending nuls 18 are disengaged from the feedscrew th the repeat or return bar 12Q, v`Themachine V Continning.to run in thefonvard diretionf tion by the' carriage isreturnedfto its initial :posi-Q the screw 12 and when approaching the starting point the arm 25 is forced outward by contact with the trip 46 set at an angle to the bar 21, until the shoulder 2G is pulled from the top of the bar 21, where upon the carriage is free to descend in contact with its feed screw for repeatilnr a record or reproducing a new record. 'lbhis trip 46 is adjustably secured in the elongated slot 22 of the bar 2l whereby the depression ofthe carriage may be varied.

I have found that heretofore the carriages upon being. dropped into engagement with the feed screw at the initial starting point, have frequently damaged vor broken the records, therefore, it is my intention to use the butler 48L at this point', said buffer being i connected to a suitable piston 47 mounted in the cylinder 48, said piston having a ball valve 49.

50 is the shaft of the magazine wheel upon which is mounted a bevel gear 51, which is adapted to be engaged by a bevel gear 52 keyed to the shaft 53. On the end of the shaft 53 is a ratchet .wheel 54.

:sol

is a dog suitably mounted on the frame of the machine.

5G is a pin to liinit'the'upward movementV of the dog 55.

57 is an arm loosely hung from the shaft 53. There are two of these arms, one on each side of the ratchet wheel 54.

58 is ay pawl having a counterweight 59, said pawl being pivotally mounted between the arms 57 in posi-tion for engagement with the ratchet wheel 54'.

G0 is a link pivoted to the arms 57 and to the lower end of a lever G1, said lever being provided with a handle (5,2 near its upper end. T his lever is pivoted at (i3 and is -provided at its upper end with a slot G4 througl'l which the arm 35 of the carriage passes in the forward movement of the carriage.

G5 is a platey secured -to the top ofthe frame and provided with an elongated slot through which the lever 61 extends.

v'66 is a plate secured upon the plate (35 and provided with forked ends 67, which register' with each side of the elongated slot in ,the plate G5.

(58 -is a bellcrank 'lever pivoted at (59 to the top of the frame 3, one end ofV which extends between the plates 65 and 66, as clearly shownin Figs. 1 and 2, and is adapted to `contact with the lever 61. ZO andv 71 are two forked end p imposed, the forked ends of plates superwhich Spaced apart in order that the other arm of tween thnv t 72is a'bracket upon which 'a lever 73 is pivoted, the upper end of said lever being Lthe bell' cranklever G8. may freely move bepositioned in the forked ends of the plates the other end to one of the arms 75, whereby' the normalv position of the arm 75 is in engagement with theends 77 of the wheel-arm. The lower end of lever 73 is forked and adapted'for engagement with one of the arms 75.

When the carriage is at the initial position on the record thelever- 61 is in the position shown in Fig. 1. As the carriage is fed along the record the hook 37 and the arm 35 pass through the slot 64' in the upper end of the leverA 61, until the pawl 41 engagesthe periphery of the cam or eccentric 45, whereupon the front of the carriage is elevated by said cam and the arm and hook i raised to a point above the slot 64 in the arm 6l. -The tooth 34 is now in engagement with the return screw 12 and as the carriage is fed in the return direction the hook 37 engages` the upper end of the lever 61 and pulls it toward the left hand side of the machine. As 4the carriage is moving toward the right handsi-de of the machinel and the hook 37 has passed through' the slot in the upper end of. th'e lever 61, the arm 40. engages the lever above the slot 64 and forces said lever toward the right of the machine thus drawing, through the link 60, the awl 58 into engagement with another toot lon the ratchet wheel 54. The lever is now practically in a perpendicular position. As the lever is being pushed to the perpendicular position it engages'the bell crank lever 68, thereby operating the lever 73v and forcing the arms 75 out of engagement with the magazine wheel.- As the machine is being returned to its initial position by means of the screw 12, the Aarm 40 moves the 'lever toward the left of the machine a slight distance and the hook 3 7 following engages the lever above .the slotJ` 64 and `forces 'it toward the left of the machine without 1turther enthe left of the machine'until the a'rm of the movement of the lever is below the hook whereuponthe hook is free to movettoward gagementI with the lever., The lever in being, forced towardlthe left of the machine revolves the shaft 53.one tooth of the ratchet wheel 54,-by memns'of theweighted 'pawl 58.

' This movement, through the bevel gear wheels 5f-aire 52l evolves e magazine ing reproduce wheel a suiicient distanceto bring the next succeeding record in position under the stylus of the reproducer, whereupon the arms 7 5,`under tension of the spring 78, snap into engagement with the outer ends of the arms of the wheel, thus holding the wheel against revolution while the record is be- During a certain period of the movement of the lever 61 the arms 75 are out of engagement with the magazine wheel,

but the reverse movement of the wheel is prevented by Treason of the dog 55 engaging the ratchet Wheel 54.

8() is a sprocket wheel mounted upon the shaft 50T" 81 is a frame mounted upon the top of the :trame 3 at the rear, in which is journaled avolved, which, by means of the-chain 88, re'- volves the sprocket wheel 87, whereupon the shaft 82 and the indicator 84:v are simultaneously revolved with the ma azine wheel and the number of the record eing reproduced is indicated 'through 4the opening 85 in the hood 86.

As soon as the twelve records are played or reproduced and itis desired to. reload-the .machine the lock is removed from the hinged end of the arm of the wheel, said hinged arm being thrown down into the depression or yoke 5 in one of the sides of the frame 3,

whereupon the record may be removed from the cylinder immediately opposite said yoke or depression. The successive cylinders are moved into this position until the wheel is reloaded with new records.

While I have shown the magazine wheel adapted for twelve records it will, of course,

be understood vthat in practiceI mayinak'e"-iY it to hold three, six, nine or twelve records, more or less.

' The shaft 89 having the knob 90 or han-A dle is adapted for connection with the Inotor (not shown), whereby themotor may be started -or stopped. f

It is my intention to have an ornamental wooden case around the machine extending upto the frame 3.

In Fig. 6 I haveshown a sli ht modification of the construction of t e magazine wheel, by nieans 'of which I am enabled to dispense with the spokes on one side of the shaft upon which the cylinders 91 are mounted. .Naturally the size of the shaft on which the cylinder is mounted would be increased in thls construetlon lnasmuch the. outer end of the shaft Will not have a support. f

In Figi 7 I have shown a Wormas a substitute for the shaft 53. In cases where I elect to use the worm inplace of the shaft i i 5ml/Will omit the dog 55 inasmuch as the *"wormf'will besuilicient to prevent a backward movement of the magazine wheel.

In the event that it is not desired torel peat a record" tlie'arm l0 is throw-nback shown.

from the position shown in Fig. 2, but in all cases when itis desired to repeat the same record the arm is thrown into the position shown in Fig.,2.

The object of mountingthe nuts 18 on the spring arms 19k is to protect the thread on the rod 11. For instance, inthe event that the carriage is let down at the `beginning of a record insuch position that the thread in thenuts-` does not exactly registerwith the.

thread on the rod `11, the nut may, byresiliency of the arm, give and automatically adjustitself to said thread, besides which slight wear in the thread of the nuts and the rod is taken up by the resiliency of these arms.

The trip i6 determining the depression of the carriage after its return to the beginning ofa record and the hook 37 determinlng the automatic return of the carriage being mounted in elongated slots are adjustable to accommodate records of different lengths.

I amaware 'that slight changes may bel made in the details of constructionwithout departing from thespirit of my invention, and hence, I would have it understood that I do not wish to be limi-tedfto the details That I claim and desire to secure by Letters Patent is 1.
