To all whom it may concern:

Be it known that 1, CHARLES W. NOYES, a citizen of the United States, residing at Cincinnati, in the county of Hamiltonand State of Ohio, have invented certainnew and useful Improvements in Phonographs, of which the following is a specification.

My invention relates to an improvement in phonographs.

Primarily the object of my invention is to devise a machine particularly organized and adapted for office amanuensis and known to the trade as the commercial phonograph.

One of the objects of my invention is to provide means in connection with the main drive of the record, reproducer, and the recorder which is under the full control of the operator when in use, so that it can be instantly started and stopped.

Another object of my invention is to provide improved means for supporting the record-cylinder.

Another object of my invention is to provide means for readily inserting and withdrawing the record and maintaining a constant initial position without destroying or varying its accuracy relative to the reproducer or recorder.

Various other features of my invention are set forth in the description of the accomp anying drawings, forming a part of this specification, in which Figure 1 represents a central sectional view, partly in elevation, illustrating the main drive for the various parts, together with the electrical connections. Fig. 2 represents a cross-sectional view showing a portion of the main power driving-shaft in connection with a train of gears for traversing the recorder and reproducer mechanism. Fig. 3 is an end elevation, partly in section, showing the means for operating the reproducer and recorder traversing mechanism for controlling the direction of traverse, Fig. 4 is a section on line a: m, Fig. 3. Fig. 5 is'a front elevation of a portion of the-traversing mechanism for the reproducer and recorder. Fig. 6 is a top plan view, partly in section, of the recorder and reproducer supporting arm. Fig. 7 is a central vertical section of the tailstook for supporting the record.

I will first describe my improved means for supporting the record-cylinder.

in the conventional phonograph taper mandrel-supports are employed. The rec- 0rd being a hollow cone brings two opposite tapered bodies into engagement. Both the record and the mandrel are liable independently to contraction and expansion, which obviouslyis constantly varying, and so destroying the accuracy of supporting the record relative to the mandrel. However. slight may be the variation, it will be sufficient to affect the meeting taper surfaces, so that the record is constantly varying in position longitudinally of the machine. As a result of this variability the reproducer must be constantly shifted to diiierent initial positions, and there is no assurance of starting a reproducer with a given record at the proper place. To avoid this, I employ a plain cylindrical record, into the opposite ends of which are fitted the driving taper disks A A. These disks, it will. be understood, compare to the live and dead center of the machinetool, one of them being rotated and the other being free to rotate on its own axis under the influence of the record.

A represents the head-stock disk, and A the tail-stock disk. The tail-stock disk is supported as follows: 1 represents the tailstock having a bore, into which is secured a sleeve 2, said sleeve being providedwith oblong slots 3. 4 represents a spindle loosely supported within the sleeve 2, provided wit a pin 5, fixed thereto, the ends of the pin projecting through the oblong slots 3. 6 repre sents a sleeve loosely journaled. on a flange 7 of sleeve 2 at one end and having an inwardly-projecting flange 8 at its opposite end, loosely bearing upon the sleeve 2. a represents a'coil-spring hearing at one end against the flan e 7 of the sleeve 2 and at its opposite en against the pin 5. Thus as the sleeve 6 is moved to the right it will carry with it spindle 4, the spring a normally forc-.

ing the spindle in a direction toward the driving-disk. The s indle 4 is provided with a cone 10, the disk .5 being provided with a central bore and race, forming one seat for the balls 11 and the cone 10 the other. i 12' represents a washer secured to the spindle 4 for holding the disk A in position on the spindle 4. By this means a free revolution of the disk A is obtained independent of the longitudinal manipulating means, yet at the serting or withdrawing the record. With these tapered disks engaging the interior periphery of the record-cylinder at each end the position of the said record will be invariable, the opposite disk taking up the expansion or contraction without varying the longitudinal position of the record. As a result the reproducer has a constant initial position, which avoids a great deal of vexation and delay inthe manipulation of the in: strument.

I Will now describe the mechanismv and oranization for driving the head-stock taper disk. This head-stock taper disk is fixed to the spindle b, suitably j ournaled in the standard C. 4

D represents the motor.

E represents an armature-shaft extending upwardly, theupper end of which is journaled upon the spindle a, supported in the standard C. The front end of the spindleb also has a pivotal engagement with the stud (I, also supported in said standard C.

F represents a magnet-core, through the center of which the armature-shaft E passes. The said magnet is fixed to rotate with said armature-shaft by the set-screw 8. This setscrew passes through the magnet-core and its end engages into a vertical slot in the periphery of the armature-shaft, which permits the magnet to be raised and lowered relative to the armature-shaft. The upper end of this magnet-core is provided with a clutch member G. In the preferred form the armature-shaft is Vertically disposed, and the clutch member G is splined thereon, so as to slide thereon vertically and to turntherewith. As a result of this arrangement clutch member G drops of its own weight when the magnet is deenergized, thus throwing the clutch members out of driving relation.

H represent a worm-sleeve journaled on the'upper end of the armature-shaft and revoluble independently thereon. The lower end of said worm-sleeve has a clutch member I, forming the cooperating clutch element to the magnet clutch member G. The spindle b is provided with a worm-Wheel 13, engaging into the said worm-sleeve. (See Fig. 2.)

f represents a contact secured to the standard C and insulated therefrom, having connection with a ring F, secured to the lower portion of-the magnet and insulated therefrom. Said ring F is connected by Wire F to one end of the magnet-coil F The opposite end of the magnet-coil is connected by wire h to the magnet-core F. Thus one pole of the electric energy has connection with the contactf, the opposite pole being through the armature-shaft and standard of the motor D. This magnet is energized and deenergizedby a push-button 14, preferably located at some point. below the machine,

' switch 14 is closed.

where it may be operated by the foot of the operator. The magnet receives its energy from a series connection with the feed, as shown in Fig. 1, as follows: 15 represents the positive wire from the main source of supply extended to the binding-post 16, secured to the base of the machine and insulated therefrom, having a cross connection by wire 17 to the binding-post 18, thence by wire 19 to one pole of the push-button or switch 14. 20 represents the negative wire from the main source of supply connecting with the contact'f. 21 represents a Wire in connection with binding-post 22, secured to the base of the machine, which is of metal, but not insulated therefrom, said wire 21 eX- tending to the other pole ofthe push-button 14, thus forming the partial circuits for the magnet, completed when the push-button or As shown in Fig. 1, the magnet is normally denergized and the clutch members disengaged. When the operator depresses the push-button, the magnet will rise and bring the clutches. in driving relation, thereby ro- 9o tating the driving taper disk through the worm sleeve and wheel. When the foot is removed from the button, the drive and spindle stops. Obviously this is a very simple and convenient drive.

I will now describe the mechanism for traversing the reproducer and recorder.

K represents a journal-bracket erected on the platform of the machine in any suitable manner for supporting the traverse-screws [00 L L by spindle n n at one end, the o posite ends of the feed-screws being journale in the standard 0. .These feed-screws are preferably o positely threaded and driven .in the same irection, whereby they are adapted to 1 5 feed the reproducer or recorder in opposite directions. Obviously the same result might be obtained by having them correspondingly threaded and driven in opposite direction or having onetr'averse screw rovided with a no reversin -gear adapted to c ange the direction of t e traverse-screw. On the spindle b is a gear-wheel 23., Suitably journaled on thestandard Cor head-stock is a transmitting-gear 24, in mesh with gear-wheel 23 and 1 I 5 also with the gear-wheel 25 on the traversescreWL. J ournaled on the standard'C is an intermediate gear 26, intermeshed with the gear-wheel 25 and with gear-wheel 27 on the forward screw L. Rearwardly projected '1 20 from the standard C is a bracket pro'ection.

, M M represent a projection from racket K in therear of the tail-stock 1.

N represents a guiding-rod eccentrically mounted in the brackets M M andprovided 12 5 with a crank-armmat the outward side of bracket M. 0 represents a push-button at the front of the machine extending upward from the platform connected by a link-andlever mechanism P P to the said crank-arm I 0 mall engage the directfeed screw;

' the traversing mechanism bodily, thereby m of the guidingrod N. Between the bracket and u on said eccentric rod the recorder and repro' ucer traversing mechanism is slidably mounted.

Q represents a downward-extending traversing arm provided with a sleeve Q, slid ing on the rod N'. Said arm is provided with an elongated slot, into which is gibbed a rack S, having vertical movements therein.

3 8 represent springs secured to the arm at one end and to the rack at their op osite ends for delicately supporting the rac between the traverse-screws L L and adapted to norhen the push-button is depressed, the eccentric rod N is vertically raised, lifting raising the recorder and reproducer supported thereon from the record. At the same time the rack, which is provided with u per and lower screw-faces of the same pitc as the traverse-screws, and at which depression the upper face of the rack is brought into en-. gagement with the feed-screw L, thereby trav ersing the reproducer and recorder in the reverse direction free from the record. Thus at an' instant the operator may cause the recor er to be shifted toward initial position for repeating the message. The" reversing traverse-screw. isalso preferably higher I s eeded than the direct traverse-screw, enabhing the operator to make a quick return s ift. j

It is sometimes desirable to hold the trav ersing mechanism free from either of the screws or to positively hold the rack of the traversing mechanism in positive, engagement with one of the screws, and this is accomplished by the following instrum'entalities: 28 represents a bracket secured to the bedplate of the machine. 29 represents a lever pivoted on said bracket. 30 represents a knurl screw-threaded onto the stem of the push-button O.- Thus by adjusti'ng this nurl 30 upon the stem the link-and-lever mechanism can be adjusted permanently for such time as desired by swin 'ng the lever 29 ii engagement with the'knur 30, as shown in 31 represents a guide of the same length as traverse-screws L L, into which the projection 32 of the traversing arm Q extends,

thereby providing a lower guiding means for the traversing mechanism, said projection 32 also servingfor the purpose of o erating the tripping mechanism 35 for soun ing the bell 34 at the end of'the traversing oint. The traversing arm Q is provided with upwardlyextending yoke-arms Q to which the recorder and reproducing supporting arm 35 is pivoted, said arm extending over the record A as shown in Fig. 2, the record being shown in dotted lines.

. In Fig. 2 I have shown in dotted lines a reproducer R and a recorder R, of duplex form, mounted upon the'arm 35, which is made the subject of a separate application and not a part of. this invention. 1

If the phonograph is to have an extended field of utility in commerciallife, it is obvious that the instrument must at all times be under perfect control of the operator and also that the controlling instrumentalities must be in such easily-accessible position as to give the operator such controlwithout unnecessary inconvenience. As the operator is transcribing the message, probably on a type-writer, it is desirable to manipulate the phonograph with the least possible movement of the hands from the keys of the typewriter. By means of the improvements here described the operator can start, stop, and reverse the machine at will and with little or no added inconvenience. Of course in reversing, the hand may be taken from the keys, as the record is not in position during the rearward traverse of the reproducer.

36 represents a switch for controlling the motor-current.

ng the speed of the motor D, having connection with the governor-39,, mounted on the main driving-shaft E.
