Application filed November 9, 1896. b'efil N0 6111562- (NO modem To @ZZ whom it may concern:

Be it known that I, GEORGE W. GOMBER, a

citizen of' the United States, residing at Conyngham, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Talking-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in talking-machines of that class in which any preferred individual tablet in a plurality or Inagazine of tablets may be brought into operative relation with the recorder and reproducer.

lhe object, therefore, of my invention is to provide a talking-machine which shall have a plurality of tablets and shall combine in close cooperative relationship automatic means for bringing any selected individual of t-he series of tablets into operative relation with the vibratory diaphragm (by which term I desire to comprehend a recorder or reproducer) by simply droppinga coin in the slot prepared for its reception and pushing one of the series of buttons corresponding to the selected tablet.

Referring to the drawings, Figure l is a front elevation of my improved talking-machi ne in its com plel e operative position, showing the diaphragm in its initial position. Fig. 2 is a top plan view of Fig. l. Fig. 3 is a sectional View of Fig. l on line A A looking toward the magazine and showing the position of the carriage and parts carried thereby by dotted lines. Fig. Liis a sectional view on line A A looking to the left. Fig. is an end elevation from the right Side. Fig. 6 isa sectional view on line B B of Fig. l looking to the right. Fig., 7 is a longitudinal section of the tablet-cylinder and the shaft therefor. Fig. 8 is a detail perspective View of my preferred form of adjustableI stop. Fig. 9 is a dei-ail side elevation of the idler and reciprocating sleeve. Fig. l0 is a detail perspective View of part ot' the controlling mechanism for the outer end of the carriage. Fig. ll is a detail view showing the supporting-axle and vthe sleeve and the head 5 carried bysaid sleeve.

While, as previously stated, the essential Vfeatures of my invention reside in the provision of a plurality of tablets and means for selectivelybringing them into cooperation with the transcribing-stylus, yet there are certain accessories which bear an important relation to these elements and which will be vhereinafter referred to as a part of my complete operative talking-machine.

In the employment of a magazine of tablets for the purpose stated l prefer to adopt that particular form of rotatable tabletholder illustrated, consisting ot' a iiXed shaft l, secured at one end by a retaining-clamp 2, af-

Iof the snugly-fitting sleeve 4, to the inner end of which is rigidly secured the fixed head 5, while to the outer end thereof is detachably secured the removable head (i. The head 6 I prefer to detachably secure to the hub or sleeve L by providing in the end of said hub an elliptical bore 7, adapted to accommodate a clamp 8, formed to register with the elliptical opening when it is desired to remove the head and to rest transversely across said aperture and against the outer face of the head when in its securing operative position.

1f preferred, an individual releasing device for each of the tablet-cylinders may be provided, though it is thought that by making provision for the simultaneous removal ot' all the tablets such means will be found amply suficient to meet the requirements, as it will be seen that each of the shafts provided for the tabletcylinders is Well anchored in its bearings provided in the iixed head, thus enabling the removable head to be taken away, allowing the tablet-cylinders to remain in their respective positions until the ends of their shafts are removed from their bearing-seats.

Upon the housing 3 for the motor I erect the standards 9 10, which are adapted to afford seats for various elements hereinafter referred to. In substantially the central section of the standards 9 10 I provide suitable bearings 11 for receiving the rotatable shaft 12, and upon said shaft, intermediate said standards, though nearer the former, I mount the idler 13. 'Ihe inner end of the shaft 12 extends through its bearings 11 in the standard 10 and is provided with the pulley or sprocket 14, adapted to cooperate with the pulley or sprocket 15, secured to the axlesleeve 4 on the innerend of the tablet-magazine. By means of said sprockets or pulleys, as the case may be, said magazine is rotated. Located upon the inner side of the idler 13 I provide the reciprocating sleeve 16, which terminates in the head 17 and is so keyed or feathered to the shaft 12 that it will rotate therewith, but will also have a reciprocatory movement thereon. The contacting faces of the idler 13 and the head 17 are provided with frictional points or pins 18 19, adapted for engagement with each other when the sleeve is moved toward the idler by the downwardly-extending arm 20, secured to the carriage-frame 2l and arranged to bear against the face 17a of the head.

The carriage 21 is held in its operative position by the shaft 22, mounted in suitable brackets or supports 23, attached to a part of the frame 24, and is adapted to reciprocate on said shaft through the medium of the barrel or sleeve 25, loosely mounted on the shaft 22 and extending to the right suiiiciently to provide a point of attachment and support for the diaphragm-carrying arm 26. By this arrangement the barrel or sleeve 25 may be freely moved in either direction upon the shaft 22, enabling the diaphragm to be moved into 'contact with the tablet. I prefer to-so mount the arm 26 upon the barrel 25 that it will tightly grasp the same and have frictional contact therewith, permitting the diaphragm to be raised or lowered by simply overcoming the frictionalgrasp,when the diaphragm will be held in au adjusted position-that is to say, the arm 26 is provided with the collar 26, which tightly fits around the barrel 25, and while the frictional grasp of said collar may be overcome it will be understood that it will cling sufficiently to the barrel to hold the arm 26 in an adjusted position.

The carriage-frame 21 extends to the front part of the machine and rests by its extreme outer end 21 upon the cam-faced shaft 27, while its inner end is rigidly secured to th barrel 25 by means of the body 2S.

The outer end of the carriage-frame 21 has depending therefrom the obliquely-disposed finger 29, adapted to raise the inner edge or blade 30 of the shaft 27 when it comes in contact- With the elbow 31, provided with the frictional rollers or sleeves 32 and 32a.

Preferably upon the upper surface of the body 28 I secure the slotted end 33 of the spring 34, provided upon its upper surface,

near the intermediate part thereof, with the threaded block 35, and upon the under side of its ou ter end with a similar block 36, adapted, respectively, for contact with the threaded shafts 37 38, by means of which the carriage is moved in opposite directions. The shaft 37 is provided with threads running to the left, While the shaft 3S has threads running to the right, and as there is sucient play permitted to the spring-arm 34 between the shafts 37 38 only one of the threaded blocks is in contact with itsishaft at the same time, providing that the carriage will be moved to the right or the left, as the case may be. The shaft 38 is provided with a suitable bearing in the upper end of the standard 9 and with a graduated pulley 39, having the faces 40, 41, and 42, the iirst being designed to connect directly with the motor in the housing 3 by the belting 43. The face 42 is designed to connect by belting with the idler 13, while the face 41 cooperates with the pulley 44, provided at an opposite point thereto upon the shaft 37. The shaft 37 is also properly seated in bearings 37, provided in the extreme inner and upper-extensiops 37b of the standards 910. The inner end of the shaft 3S passes loosely through an aperture provided in the upper end of the standard 10 and extends into engagement with the bearing-point 45, held in an adjusted position by the downwardlyextending section 46 ofi the lateral continuation 47 of the standard', 10. It will be understood that all of said shafts may be provided with bearings of this character in order that a minimum amount of friction may result, though any desired fogrm may be employed.

The lateral extension 47 is designed, in addition to providing a bearing for the eXtreme end of the shaft 38, to carry or suspend the sprocket-frame 48, in the outer ends of which are mounted the sprockets 4H 50, intended to be actuated by the sprocket 5l, mounted ou the extreme end of ,l the shaft 38. These sprockets when properly connected by a suitable belting are intended to act upon one of the sprockets 52, secured to the inner end of the shaft of the tablet-cylinder, and as the sprocket 51 is disposed slightly above the sprockets 49 50 the belting will reach across from the under side of said sprockets and freely contact with any preferred one of the sprockets 52 as its accompanying tablet'is broughtinto cooperation with the diaphragm. For this purpose it isthought that a belting constructed of suitable pliable material provided with eyelets for engaging with the teeth of the sprockets will be found most suitable, though ordinary leather belting provided with suitable apertures to ',receive the sprocketteeth will, it is thought, be found to be stiflicient to meet the requirements, yet by protecting the edges of said apertures with metal eyelets a much longer life is imparted to the belting, rendering it more desirable for the purpose.

In order to hold each of the shafts 4 of the IIO tablet-cylinders in its operative position and to accommodate a suitable form of bearing therefor, I provide upon the fixed head the inwardly-extending sockets 5, having a sufficient bore to loosely receive the inner ends of the cylinder-shafts 4, which are received and held in position by the adjustable bearingpoints 5b, axially seated in the ends of said sockets. The extensions or sockets 5 also provide a seat upon their upper surface for the reception of a series of disalined stops 53, so located that none will move in the plane or path of the others and designed to contact with their respective tumblers when the desired tablet is in apposition with the diaphragm.

Mounted in the rear part 24 of the frame of the machine, at a point on a line with the disalined stops 53 and designed to contact by proper manipulation with their respective stops, I provide a series of tumblers 54, arranged to reach through suitable bearing seats or apertures 55 in the frame, While pivotally connected to theinner ends 56 ofsaid tumblers is the operating-bar 57 for each ofthe tu mblers 54, preferably extending upward from the point of their pivotal connection with the tumblers on the rear side of the frame and parallel therewith. Said apertures 55 are of suficient extent to admit of a free upward movement of the tumblers 54. By this arrangement of the apertures the tumblers 54 will rest upon the lower end thereof and check the downward movement of their respective stops; but when the magazine is reversely rotated each will move out of the path of its stop when contacting therewith from the lower side. Each of the bars 57 is provided, preferably nearits upper end, with a pivotal connection or bearing 58, secured to the rear side of the frame. Designed to normally withdraw the tumblers 54 is the spring 59, one end of which is anchored in the inner edge of the bar 57, While the free end thereof is arranged to bear against the frame, thus withdrawing the tumblers. To the upper ends of the bars 57 I pivotally connect the operating-lever 60, arranged to extend through suitable apertures 6l, provided in the frame, to the front side thereof, where they terminate in or connect with suitable manipulating-buttons 62 for manual control. In order to dispose the series of operating-buttons thus provided within a convenient area and position, I prefer to graduate the length of the series of bars 57, arranging that the bar upon the right or left shall be shortest or longest, as may be preferred, and graduallyincreasingordiminishingthelength of the other bar, the case may be, resulting in the arrangement of the buttons in a line with each other, substantially as shown in Fig. l. This is a preferred form of arrangement for the operating-buttons, though it will be understood that any convenient and preferred plan may be adopted for this purpose.

For cheap, and consequently expeditious, construction I prefer to form the bars and -plete series of stops.

tumblers 57 and 54, respectively, of wood, arranging that a simple saw-mark in the inner edges of said bar will provide a seat for the spring 59, though for more permanent construction it will be understood that these parts may be formed of any preferred material. By the disposition made of the spring 59 it will be observed that the respective button of each bar will be held normally outward, when a pressure upon said button will enable the tension of the spring 59 to be overcome, thus forcing the tumbler 54 into the path of its respective stop, all of which for convenience are designated by the numeral 53.

Frein the drawings and specification in this case it will appearthat it is the function of the stops 53, respectively, to engage each its appropriate tumbler 54, and thereby to determine automatically which one of the tablets of the magazine shall assume operative relations with the vibratory diaphragm. The actuation of one tumbler causes the mechanism automatically to select a particular stop and no other. In like manner the actuation of another tumbler causes the selection of another. stop, and so on throughout the com- Now the employment of cooperative stops and tu inblers is in tended only to illustrate one mode of accomplishing an object that may be accomplished in a variety of ways and is representative in the broad sense of any mechanism that is adapted to select any one of a series of tablets in preference to any other. Therefore for brevity and convenience I denominate such mechanism tablet-selective mechanism, intending thereby to include any mechanism that is adapted, through the manipulation of a meinber-in the present example one of the tumblers 54-to select for operative relations with the vibratory diaphragm any individual of a series of tablets that may be determined upon irrespective of the relation in which the tablet selected may stand toward the other tablets of the series.

The cam-faced shaft 27 is mounted in suitablev bearings 63, located in the outer ends of the brackets 64, the latter being so connected to the standards 9 l0 that said shaft will be held slightly above though parallel with the shaft l2. At the foot of the standard l0 and at the forward edge thereof I provide the pivotal seat 65, arranged to receive the lower end of the standard 66, which extends upward parallel with said standard and is provided upon its upper end with the obtuse angle 67, presenting a cam-face 67 a for contact with the friction roller or sleeve 32a, mounted upon the elbow 3l, secured to the shaft 27. 'lo the opposite end of the shaft 27 and extending inwardly therefrom parallel with the blade 30 I provide the controlling-lever 68, which has pivotal connection with the crank-arm 69 by means of the link 70. Said crank-arm is rigidly connected to or integrally formed with the rocking shaft 7l, which is disposed parallel with the longitudinal line of the ma-l IIO chine and is mounted in suitable bearings 72 and consists of the body-section 73, the transverse arm 74, and the terminal branch 75, adapted to bear upon the upper edge of the tumblers and prevent the upward extension or movement thereof. The connection between the shaft 27 and the rocking shaft is so made that the elevation of the edge or blade 30 will result in the depression of the terminal branch 75 into contact with the upper edge of the tumblers, preventing, as previously stated, an upward movement thereof until said branch has been elevated by the corresponding depression of the blade 30.

In order to automatically provide for the actuation of the terminal branch 75, I provide near the outer end of the carriage-f rame 21 the inclined guide or radially-disposed finger 29, which will, as the carriage moves to the right, contact with the friction roller or sleeve 32 and cause the same to ride upon its inclined face, resulting in the elevation of the inner edge or blade 30 and the partial rotation of the cam-faced shaft. The elevation resulting from this contact of the friction-roller with the inclined face of the depending linger 29 causes the friction roller or sleeve 32a to ride upward against the outer face of the lever 66 until the obtuse angle 67 has been reached, when the upper end 67a of said lever will be forced outward against said sleeve, causing the same to ride upon the inclined face 67, through the action of the spring 76, so disposed that its free end will bear downward upon the outward extension 66a of the lever. The opposite end of the spring 76 is suitably anchored at any preferred point where its oflice may be most effectively performed.

The operation of my improved automatic talkingmachine may be described as follows: That is to say, the carriage is placed in its initial position at the extreme left end of the threaded shafts,when the diaphragmarm is depressed, overcoming its frictional grasp upon the barrel 25, bringing the diaphragm into the plane of the surface of the tablet, which has first been placed in position by a pressure upon its corresponding button,

duly labeled to indicate said tablet. The motor is then started, either manually or automatically, by aid of a suitable prime mover, when the threaded block 36 will engage with the shaft 38, resulting in the lateral movement of the carriage in unison with the threads provided on said shaft, causing the stylus, with its accompanying diaphragm, to follow the line of record provided on the tablet until the extreme outer end thereof is reached, when the depending radially-disposed finger 29 will engage with the frictionroller 32, elevating the elbow 31, and thereby causing the friction-roller 32 to travel upward upon the face of the lever 66 until the obtuse angle 67 thereof is reached, when the action of the spring will force said lever outward, contacting the face 67 of said lever with said roller, and complete the elevation of the blade 30, incidentally causing said blade to act upon the outer end 2lu of the carriage and forcing the threaded block 36 out of engagement with the shaft 38 and bringing the threaded block 35`iinto coperation with the shaft 37, effecting the reverse movement of the carriage. The elevation of the blade 30 also results in the upward movement of the controlling-lever 68, acting upon the rocking shaft 71 in such manner as to cause the terminal section 75 thereof to move downward into contact with the upper edge of the tumbler, holding the same in a horizontal position, preventing a continued reverse 1novement of the tablet-magazine.

It will be understood that each of the buttons controlling its respective tumbler will be labeled or designated in any preferred manner to correspond withltbe subject or selection inscribed upon the tablet located at its respective stop, enabling the operator to make a selection of a subject and bring the same under the reproducing-stylus by a simple pressure on the button.

The adjustment of the several parts is so made that the contact of the tumbler with its stop will place the desired selection under the stylus, bringing the sprocket 52 into engagement with the belting upon the sprockets 49 50, which latter, as previously set forth, are actuated through the medium of the lsprocket 5l, located upon the shaft 38. The

movement, therefore, of the shaft 38, in addition to a positive actuation of the carriage, also rotates the tablet-cylinder, enabling the diaphragm to travel in harmony with the line of record.

In order to provide aconstruction for the tablet-cylinder which will compensate for the expansion and contraction incident to changes in the temperature, I prefer to provide that the surface of the shaft 4 for the cylinder-body 4J shall be suitably roughened or finely corrugated, upon which is shrunk or forced the body proper, 4b, preferably made of light porous wood, cork, or the like, while upon the outer surface thereof I secure a covering 4, of a flexible and loosely formed fibrous material-such, for instance, as canvas, canton-flannel, or the like-the object being to provide for the free expansion and contraction of the material forming the tablet.

The stops 53 may consist for cheap and eicient construction of a series of screw-threaded lugs or points properly seated in the outer face of the sockets in such manner that each will engage with its respective tumbler and be disposed in an entirely-different path from the other, or said stops may consist of the adjustable device shown in Fig. 8 and consisting of the plate 53a and the integrallyformed point 53. In either end of the plate I provide the slotted apertures 53", designed to permit longitudinal movement of the plate 53, that the stop may be properly adjusted. If the form of stop consisting of the threaded lug or point be employed and it should be lOO IIO

IZO

necessary to readjust it after it is seated in the outer face of the socket, such readjustment can easily be effected by simply bending the point in the direction desired, which of course will be readily appreciated.

Upon the shaft 12 ismounted the idler 13 and the sleeve 16, as previously stated, andsaid sleeve is designed to coact with the depending arm 20, provided upon the carriageframe 21, as follows: When the carriage has moved back into its initial position, the bearing-block 35 will drop into the groove 77, (said groove being a reduced portion of the shaft 37,) when the blade 30 will tend further to elevate the carriage-frame 21 and its accompanying depending arm 20, bringing it to bear against the face 17u of the sleeve, forcing said sleeve and the friction-point 19 thereon into engagement with the idler and the friction-point 18, secured thereto, thus connecting said idler to the shaft and resulting in its rotation and incidentally rotating the sprockets 14 15, causing a reverse movement to be imparted to the tablet-magazine until the stop bearing upon the upper side of its tumbler is moved entirely around to contact with the lower side thereof, thus bringing the magazine to a full stop, owing to the interposition of the terminal section 75.

It will of course be understood that I do not wish to be confined to the use of belting as a means 'for communicating power from one pulley to another, as toothed gearing or other equivalent may be used, if preferred. For instance, the sprockets 14 15 may be toothed gearing arranged to mesh with each other in the usual manner, thus dispensing with the necessity of other means for forming connection. The same may be said with reference to the sprockets 51 52 and other parts now shown as connected by belting.

In order to make it clear how I retain a flexible covering of felt, canvas, or other preferred material upon the porous body of the tablet-cylinder, I will state that said covering may be so placed that the projecting edges thereof will extend past the ends of the body of the cylinder, where they may be drawn inward toward the shaft and there secured against the ends of the body by a suitable retaining-plate 4d and retaining-screws ete or other preferred means, taking through said plates into the body.

In order to provide that the tablet-magazine will be reliably held in an adjusted position, to the end that the subject-matter upon any preferred tablet may be transcribed, I arrange the locking mechanism for the magazine, (more clearly shown in Figs. 3, 5, 6, and other views,) and which I will describe by stating that the sprocket or gearing wheel 15 is provided upon the face thereof or other preferred point with a series of notches or teeth 78, adapted for engagement with the detent or pawl 79. The lower end of the detent 79 is pivoted in a suitable seat 80, mounted at any convenient point to enable it to perpreferred one of the tablets is being transcribed.

The operation of the locking device may be stated as follows: When the elbow or inner edge of the blade, to one of which the linksection 82 is attached, is depressed,the crankarm 81 will be moved downward, forcing the free end of the detent into engagement with one of the notches or ratchets 78, thus locking the sprocket or gearing 15 against movement until the detent is Withdrawn. The downward movement of the elbow or blade just referred to occu rs only when the diaphragm is brought into coperation with the tablet, consequently resulting in holding the magazine in a fixed position until the diaphragm has traveled the entire length of its tablet. When the stylus has transcribed-the entire line of record, the diaphragm is automatically returned to the starting-point, as already described, through the elevation of the blade 30, which act results in the withdrawal of the detent 79 from engagement with the sprocket 15, permitting another selection from the magazine-tablets to be made.
