HENRY 3'. KING, OF NEW HAVEN, CONNECTICUT, ASSIGNOR T0 DIOT'APHONE COBPORA- TION, OF BRIDGEPORT, CONNECTICUT, A CORPORATION OF NEW YORK PHONOGRAPH Application filed December 14; 1928. Serial No. 680,646.

This invention relates to phonographs, and more particularly to commercial phonographs used to record and reproduce dicta-' tron.

An object of this invention is to provide for preventing damage of the sound recording or reproducing means by the record-tablet.

when the latter is being introducedto the machine.

Another object is to provide for preventing damage of the surface of the record-tablet by the styli, or' other parts of the recording or reproducing mechanism when the recordtablet is'being placed in or removed from the machine.

A further object is to automatically cause the means for preventing damage of the record-tablet and styli to e operated. A still further object is to cause the damagepreventing means to be automatically operated as an incident to a usual and customary operation, which the user of the machine performs after the record-tablet is removed and which has already been performed before a new record-tablet is placed upon the machine. I

Andv a still further object of this invention is to provide means for allowing the removal ofa record-tablet without disturbing the setting of the machine. And yet another object is to provide for entirely concealing the most delicate parts of the machine when the'latter is out of use.

i :to perform the necessary operation, which is usually subconsciously performed, should tating machine, showing the parts in the pofective'.

Another object is to enforce the operator Other objects will hereinafter appear.

' Fig. 7 is a bottom plan view of the mechanism shown in Fig.

The dictating machine shown in the accompanying drawing, comprises a base 10 having upright standards 11, carrying suitable guides 12 upon which the sound-box carriage 13 is mounted to move longitudinally on the machine under the influence of afeedscrew 14. suitably coupled to the carriage by means ofa feed-nut 15. The sound-box carriage travels over a record-supporting mandrel 16 supported in suitable hearings in a housing 17, at the left of the machine. The mandrel is preferably provided with springpressed plungers 18, which makes it self-adjusting to all record-tablets irrespective of the slight variation insize due to irregularities of manufacture and temperature changes.

The sound-box carriage 13 has at its for- 'ward portion a nozzle 19, adapted toreceivc the end of the speaking tube 20, having at this mouthpiece 21 and speaking-tube 20, that its other end a mouthpiece 21. It is through the sound emitted by the dictator is carried to the machine. The sound 'is conveyed through suitable internal connections to a sound-box 22, having a diaphragm 23, carrying a recording stylus 24 and a. reproducing stylus 25. The sound-box 22 is mounted to swing vertically upon trunnions 26, so that it may assume the proper position with one of the styli on the record-tablet, both when the newrecord-tablet is used and when a shaveddown record-tablet is used. The horizontal mounting of the sound-box 22 is also provided to allow raising of the styli fromthe record-surface when, for instance, it is desired to change the longitudinal osition of the carriage, or when shifting rom recording to reproducing position, or vice versa. This movement is effected by means of a lever 27, pivoted upon the upper guide 12, and having a link 28 connected to a slide 29 carrying the sound-box. The movement of the lever 27 causes the slide to be moved, and'this, because of a cam surface 28a on the sound-box and a pin 29a on the carriage, causes the sound-box to be raised off the record-surface. At the same time, the feed-nut 15 ,is withdrawn from the feed-screw 14 by means of a cam surface 30 on the lever 27.

For the purpose of facilitating the removal of the record-tablet from the mandrel, there is provided a record-ejector comprising a plunger 31a adapted to engage the inside end of the record-tablet. This is preferably operated through a link 31b by a lever 32a located adjacent the free end of the mandrel as illustrated in the patent to J. M. Lucarelle, No. 1,687,375, October 9, 1928, so that, with one. hand, the operator may simultaneously operate the re'cord-ejector and receive the ejected I record upon the fingers of the same hand. It will be seen, from the foregoing, that should the record-ejector be operated, or the recordtablet be otherwise removed from the mandrel while either of the styli is in operative position upon the record-surface, this surface will be scratched or otherwise damaged by the relative movement between it and the stylus. This usually results in marring the surface of the record-tablet to such an extent that the recorded matter is unintelligible in the case of a tablet with the sound record on it, or rendering a new record-tablet unsuitable for use. On the other hand, it will be seen, that because of the freedom of the sound-box to move downwardly, the advancing end of the record-tablet being placed upon the machine while the sound-box is in its lower position would engage the sensitiveand rela-" tively fragile points of the st 1i and break them from their connection to t e dia hragm, or otherwise damage them and ran er them unsuitable for use. f

Consequently, heretofore, it was'necessary for the operator to throw the control lever 27 to its neutral or inoperative positiddbefore applying or removing'the record-tabletfrom the machine in order to avoid this difiiculty. This operation is easil performed, but, very frequently, particualr y with those not fully acquainted with the operations of the machine, the operator would forget to shift thelever 27, withthe result that the record-tablet or the styli, or both,'would be damaged when the record-tablet was being applied to or removed from the machine.

It has been proposed to avoid this difficulty by putting blocking means, or lockin means, in such positions that the removal of the record-tablet is prevented unless the control lever be put in neutral osition. These proposals, however, merely orced the operator to shift the control lever to neutral position before removal of the record-tablet was permitted. Moreover, for various reasons, these proposals, while they could prevent removal of the record-tablet from its support, could not prevent its movement on the mandrel, with the result that the record would be scratched by the stylus before the blocking means came into play.

It is the main object of this invention to avoid these difficulties and, according to the preferred embodiment herein shown and described, this is accomplished by bodily lifting the sound-box from the record-tablet when the operator concludes the dictation; and this is done as an incident to an operation which the operator subconsciously performs.

This operation-is the placing of the speaking-tube 20 upon a hook 31 at the left of the machine. This hook is pivotally mounted upon a bracket 32 and has its rear end 33 provided with a connection 34 to a sw1tch 35 controlling the motor circuit of the machine. When the speaking-tube 20 is hung upon the hook 31 its weight moves the hook 31 downwardly against the tension of its spring 36 (see Fig. 3) and causes the motor circuit to be opened. This operation of placing the speaking-tube upon the hook 31 is performed by the o erator each time he ceases dictating and this is done from the very beginning of his use of the machine. It is a subconscious operationthe same as that of hanging the telephone receiver upon its hook when a telephone conversation is concluded.

For bodily raising the sound-box 22 for the purpose of protecting the record and the styli, there is provided on the sound-box carriage 13 a lever 40 pivoted at 41 and having a hook 42 at its forward end adapted to engage the forward portion of the sound-box 22 when the lever is swung. The hook 42 of the lever 40, in its normal position, is below the lowermost position of the sound-box,'s'o as not to interfere with the free up-and-down movements of the sound-box in accommodating itself to record-tablets of various thickncsses. The rear end 43 of the lever 40'extends outside of the frame-work of the car riage 13 and into position to be operated by a bail 44 fulcrumed at 45 in the vertical standards 11. There is merely a contact enga ement between the end 43 of the lever 40 an the bail'44 so that the bail may operate the lever in any of the positions of the carriage. The ball, at the left side of the machine, is provided with an arm 46 having a link 47 connected to the rear end 33 of the speakin -tube su porting hook 31. \Vhen the hook 31 receives the speakin -tube, its rear-end is raised causing the bai 44 to be swung downwardly. This engages the rear the sound-box and raises it to its extreme upper position where it is far out of range. 0

the record-tablet and isconcealed behind the frame-work of the sound-box carriage, see Fig. 2.

It will thus be seen, that when the speaking tube is on the hook, it is absolutely impossible to either damage the record-tablet by the styl-i, or the styli by the record-tablet, and that the latter may be removed without performing any other operationthan ejecting it from the mandrel, by operation of the lever 32a.

Sometimes it is desired to remove a partly dictated record-tablet from the machine, for example, to allow the typistto reproduce and typewrite what is there recorded, and to again replace the record-tablet to continue the dictation. To do this, it was previously necessary to throw the control-lever 27 to its neutral position so as to lift the styli from the record-tablet and prevent any damage. But this operation, it will be remembered, also removes the feed-nut 15 from the feed-screw. Consequently, when the controllever 27 is in its neutral position the carriage is free to move in any direction and to get out of the position occupied when the dictation was interrupted. Therefore, when the partly dictated record-tablet was replaced upon the machine, it was also necessary to I reposition the carriage, a rather tedious operation, in order to continue where the interruption took place. This is not necessary with the present invention because the placing of the speaking-tube upon the hook 31 raises the styli from the record-tablet without releasing the feed-nut 15 from the feedscrew 14, and this, of course, may be done for any purpose whatsoever.

The movement of the sound-box to a position where the styli are concealed entirely withinthe carriage frame is also a particularly advantageous feature, for it prevents damage to the styli by tools, or other implements, when the machine is out of use.

While there is herein described, one embodiment of this invention wherein the sound-box is raised from the record-tablet by the performance of a subconscious operation,

the hanging of the speaking-tube upon the hook, it should be distinctly understood that the invention is not limited to this particular construction, but that any other operation which may be done at the conclusion of dicraising the sound-box ofi' the record-tablet without altering the connection of the carriage feed-nut tothe feed-screw may be performed by any suitable means,

and this may be entirely independent of any other operation of the machine.

This may be done, as shown in Fig. 5, by

53 to a part which operates the sound-box raising lever 40.

In Fig. 5 there is also shown a modified form of mechanism for lifting the sound-box from the record tablet. This comprises a triangularly shaped bar 54 pivoted on the frame of the machine and having at one end an arm 56 connected by a link 57 to an extension 58 of the speaking-tube supporting hook. The bar 54 also has its arm 56 connected to the link 53 of the key mechanism. When either the key 50 or the speaking tube book 31 is depressed the triangular bar 54 .is

rocked, bringing one of'its points into en- I 62 to which it is attached is in its uppermost position, movement of the record ejector is positively prevented. The lever 62 is pivoted at 63 and has its rear end 64 connected by a link 65 to an arm 66 on the shaft 45 of the bail 44. The connection is such that when the bail is in its uppermost position, where it allows the sound-box to engage the recordtablet, the lock 60 engages the ejector lever 32a to prevent its operation. When the speaking-tube is hung upon its hook 31, the bail is, of course, rocked downwardly to raise the sound-box from the record-tablet as previously described. causes the lock 60 to be withdrawn, and a free operation of the record-ejector is then permitted.

It will be seen that by providing this lock for the record-ejector in combination with the speaking tube controlled sound box raiser it is impossible to remove the record so long as the motor switch 35 is closed and the motor is operating. Consequently, according to the present invention, it is impossible to attempt to withdraw the record from the machine by operatiop of the recordejector so long as the mandrel is rotating.

It will of course be understood that other forms of record-ejecting mechanism and other forms of locks may be used within the scope of this invention and that portions of the improvements may be used without others all within the scope of the appended claims.
