'Specication o Letters Patent. Patented Oct., 22,1912, Application filed November/I6, 1908.- Serial No. 462,783. v

To all whomit may concern;

Be ,it lcncwnthatl, JOHN H. J. Haines, a citizen of the United States, residing at the city' of New York, in the borough of Manhattan and State :of New York, have invented certain new and useful Improvements in Phonographs, o i' which the follow'- ing is a full, clear, and exact description, l

rlhis .invention :relates to phonographs and other styles of talking machines in which the record is traced in atabletl in the :t'orm of a groove varying in depth in accordance with the vibrations of the sounds of. talking machine it has been customary to employ one 'devlc'e'for recording sounds and another for reproducing them. These devices each comprise essentially a. diaphragm mounted in a. sound box and carryingA a stylusllwhich engages the surface of vthe; record tablet. In= the recorder the stylus is caused to cutagrcme of vary-ing depth in the recording surface, while in the repro,-

' ducer the stylus, which is of slightly differentrconstruction, is adapted to traverse-the groove formed by the recorder and to transfer l'the undulations of the groove successively to the diaphragm. Anfessential difference in these two devices is that. the reproducer when-in action rests more heavily against the record surface than doesthe recorder. The reason forthis is that in recording, the instrumentshould be in a nearly floating condition with its stylus located so as to. just cut the record surface land its movements not be interfered with by the inertia of theirame in which the di'ardiraglm` words 1t mustl be `as` is supported. In other sensitiw-'e as possible to sound vibration. In the reproducer, on the contrary, `=the -device would not act properly if it were in afloating condition because the irregularities or" the record groove which are driven against the stylus' by `the rotating Atablet would cause stutter and give imperfect reproduction. Therefore. in-A the reproducer it is the common practice to add weight to the frame on which the diaphragm a nd stylus are supported, s'o as to hold the stylus to its work in V,the groove. Hence,

' aside from the difference in the form of the 'stylus points, the essential difference between a' recorder and la reproducer is that t the latter is heavier than the former.

'Heretofore and prior to my. invention it has been customary, where the talking machine is intended Jfor both recording and reproducing, to provide the machine with two separate and distinct devices, one to be used for the recording, and this to be removed and replaced by the other, for reproducing.

lt is the object of my invention to provide in one and the same instrument, both the recording and reproducing devices, and in so doing to utilize a single head which comprises a diaphragm1 sound box and frame. ll accomplish this by providing a weight or spring so arranged that when the head is in` a position to record, it will be independent ot and uninfluenced by the weight or spring, but when the head is thrown into a position to reproduce, the weight-'or spring is automatically brought to bear upon it so as to afford the necessary additional pressure against the record surface required in the reproducing operation.

` To be` more specific, my invention consists lof a recorder-reproducercomprehending a single diaphragm having attached thereto a recording and a reproducing stylus, means for bringing into active position either one of the styluses atwill, and means whereby a weight or the force of a spring will be added to or removed from the instrument accordingly as the reproducingor the. recording stylusesare thrown into action. My invention thus very much simplifies the operation of talking machines as well as reduces their l cost and the time ordinarily required to yshift from the recording to the reproducing device .is .almost entirely saved.

My invention will be now described with reference to the accompanying drawings, in

which:

Figure 1 is a 'plan of -a portion of the .trame ot a phonograph, showing my .oom- ,bined recorder and reproducer 1n operative position thereon 'and utilizing a weight instead of a spring; Fig. 2 is an end elevation of the same machine with the recorder-reproducer adjusted for the ,recording operationj` Fig. 3 is a view similar to- Fig 2 with the recorder-reproducer adjusted for the reproducing operation; Fig. i is a vieuT showing the device in condition for recording, but with a spring substituted forthe weight; Fig. `."5 illustrates/a'modification in the. construction of Athe weight in connection with a modification of the manner of shitting the stvluspoints; Fig. 6 is a section on line X-X of FigQ; and Fig.7 is a section on line Y-rY'jofFig. 5. 1

Referring to the drawings by numerals, 1 indicates the frame of the phonograph in which is mounted the tapering cylinder 2 which supports the record tablet in the form of a cylinder and indicated by 3.

1 is a rod along which the carriage 5 travels.

The recorder-reproducer consists of a sound box or frame 7 in whichis mounted the diaphragm, and a Atubular arm 8 to which the sound box is pivoted at 9 and which communicates with the interior chamber thereof above the diaphragm. The arm 8 is connected by means of a universal joint 10 with the carriagel 5 and the latter is providedwith a nipple 11 to receive the end of a flexible tube and through which a pas sage leads into the arm 8, thus forming a. continuous sound passage from the upper side of the diaphragm to and through the flexible tube, the outer end of which is to be attached as usual to the mouth piece or horn.

At or near the center of the diaphragm are fixed two

stylus points

12 and 13, the

- 9 serving as a stop.

Ament with the record tablet.

15 is a lever pivoted. to the end of arm 8 and having lan eccentric lug 16 which is adapted, in oneA position of thelever, to bear against and tiltl the sound box 7 into Ian oblique position, as shown in Fig. 3, while when the lever is thrown upward into its other position as inFig. 2, the sound box is permitted to return to a horizontal position under the action of and be held by, the

spring 1&1. When the sound box is in the horizontal position, the recording stylus 12 is in position to engage the record surface of the tablet 3, as seen in Fig. 2, and lwhen the sound box is in the oblique position, the stylus 12 is thrown out of contact with the record surface and the stylus 13 is thrown into'op'erative position therewith.

Pivotally attached to the carriage 5 at the point 16 is a bracket 17 provided with a lug 18 adapted to be engaged by another lug 19 which is manipulated by a hand lever 20 to raise and lowerlthe instrument. The instrument for the purpose, is provided with a tongue 21 which bears against al shoulder on the bracket 17 as shown, so thatywhen the bracket is swung upward, the instrument is raised and can be moved along the rod 4 to any desired position and when the bracket is lowered, it will drop into engage- Thfis device for raising and lowering the instrument is an ordinary one and forms no part of my 6.5 present invention. Preferably attached to this bracket 17, however, by means of a pivot 21 is a weighted lever 22, being a bifurcated plate embracing the opposite sides of the tubulai` arm 8. This lever has a projection 23 carrying a set screw 24 which may be adjusted to determine the elevation of the lever when supported at its lowest point. The weighted lever extends over the inner edge of the sound box 7 and the screw 24 is so adjusted that whenthe sound box is in the horizontal position shown lin Fig. 2, the weight is supported wholly by the bracket 17` and is entirely clear and independent of the sound box or speaker-,but when the sound box 7 is tilted to the oblique position shown in Fig. 3, the inner edge of the sound box strikes and lifts slightly the weight so that. the latter rests upon or is sustained by thelsound box.

The operation is as follows: When the instrument is used as a recorder, the lever 15 is raised to the vertical position, as shown in Fig. 2, and the sound box allowed to assumel its horizontal position, thus bringing "the recording stylus 12 into active position and relieving the instrument of the weight v22. The record is then made in the usual way by transmitting the voice or other sounds through the tube to the top of the diaphragm. lVhen the record has thus been made, if and when it is desired to re r0- duce, the lever 15 is thrown downwar to the position shown in Fig. 3 which'renioves the recording stylus 12 and simultaneously throws into active position the reproducing stylus 13. .At the saine time the forward upper edge of frame 7 strikes and lifts the lever 22- thus transferring its weight from the bracket 17 or other partnofmthe frame to which it may be attached, to the sound box frame. This weight which is thus added to the instrument is of the Jroper amount to parts, but that it merely requires the operator 'to shift the position of lever 15. The cost of this combined device is only a trifle more. than that o t either the recorder or repl'oducer alone and no skill is required to make the change from one to the other.

' The construction of Fig. ft is the equivalent in every sense of that of F igs. 1 to 3. since v a spring is used instead of its equivalent, the weight. ln tl'iis'vconstruction' the weight becomes a. mere lever 25, having the saine stop screw- 24, but provided with a tension spring 2G which/tends to throw the lever "25 downward with a force dependent upon the noaa-:tio

fot', the sound box; it is pivoted to the carriage at 28 and rests upon a lug 29. carried by a pivoted lever 30, which lever is to be manipulated by hand. The stylus points radiate from a hub 30 which is pivoted to brackets 3l attached. to the diaphragm. The hub is fixed upon a'roclr-shaft 32 which also carries a fork 33 between the legs of which is a pin 34; carried by lever 30. lVhen lever 30 is swung to one side 'or the.other, the styluses are shifted and the weight 35 is raised or lowered by the lug 29, thus either lifting the weight from or addigjit to the instrument.

The essential eaturel of my invention 'therefore is any structure comprising the elements common to a recorder and a reproducer in combination with a weight or its equivalent adapted to be added `thereto or removedtherefrom according to the requirements ofthe operation.
