SOUND IRECGIBI)ING:A AND REPRODUCING MACHINE.

Application filed June 1, 1917.

To all whom 'it may concern:

Be it known that we,DA\'1D FREDERICK MC- QUIRE and KENNETH DOUGLAS MCQUIRE, both subjects of the King of 'Great Britain and Ireland, and both residing at Braemore, Herbert Road, Hornchurch, in the county of Essex, England, have invented certain new and useful Improvements in Sound Recording and lReprodu'cing Machines, of which the following is a specification.

This invention relatos to sound recording and sound reproducing machines employing disk records and of the type adapted both for the recording 0f sounds and for the rcproduction of sounds thus recorded, the invention being principally adapted for domestic and oiiice use.

The object of the present invention is to provide an improved form of machine of the above character in which the reproduction of therecorded sounds may be effected through the usual tone arm, sound chamber or amplifyinghorn without damage to the record, due` tothe fact that by reason of our construction the recording stylus or like member and the reproducing member both move across the face of the record in the same path instead of as is usual the one member moving in a rectilinear path and the other in a curved path.

The invention consists in a sound recording and sound reproducing machine comprising in combination a record supporting member, a tone arm, a member movable rectilinearly across the face of the record and means connecting the tone arm with this latter member but slidable upon said member.

The invention also comprises a sound recording and sound reproducing machine of the above character having a carrier for the recorder and reproducer, rotatable about a vertical axis, so that either the recorder or reproducer may be moved into its operative position.

The invention further comprises other de! of device in accordance with the invention Speciication of Letters Patent.

Serial No. 172,304.

Fig. 2;

Fig. 11 is a view showing a detail; while Fig. 12 is a view illustrating a modified form of reproducer.

In carrying our invention into e'ect in one convenient manner as, for example, in its application to a machine of the gramophone type, we provide the usual turntable a driven by any suitable motor (not shown) and Vlocated within a cabinet b if desired. Upon the cabinet or framework t we mount a pillar c (or the same may be independently mounted) and upon this pillar or support c' and a socket J upon the spindle e of the turntable we arrange a tubular or other carrier f adapted to support a sleeve or like member g and. provided with suitable means for moving the sleeve or the like longin tudinally or axially. For example, the sleeve or the like g may be fitted with a half nut (not shown) adapted 'to engage a longitudinal screw t driven from the turntable by shaft z' and bevel gearing la and fitted with any usual form of half1 nut or other quick release actuated by the milled head or other member Z, substantially as shown 1n English patent of Thoshann, 22,268 of 1914, this subject matter forming per. se no part of the present invention.

The sleeve g is encircled by a second and shorter sleeve m', which is rotatably mounted thereon, the amount of rotationl of the sleeve being limited by a projection m2 on the sleeve coperating with the upper part of the guide bracket :v and this sleeve m carries a bar m. By rotation of the sleeve 1n the .proper direction the bar m may be swung vertically from the position Shown in full.

' lines, the bar by means of its sleeve being capable of being rotated into the position shown by the dotted lines in Fig. 1 when it is desired to clear the machine or otherwise disconnect, or vice versa.

A member n has a forked lower end n which straddles the outer end of the bar m and t0 the member n is connected a clamp or support 0, which encircles the tone arm.

A convenient manner of effecting this adjustable connection is to provide the clamp o with an angularly turned upper end o to which is connected the lower end of a screw rod e' and which has an extension o2 working in a lvertical slot or bifurcation in the member n. A spring a tends to force the angular bent part 0 in a downward direction, while it may be drawn upwardly against the tension of the spring by a milled nut 22 bearing against the upper face of a bracket member 'n2 supported by the member n. The bar m thus supports the weight of the tone arm p or other member carrying the recorder g and reproducer 11, and when in operation ment to the tone arm.

The clamp 0 heilig adjustable vertically permits of the use of recording blanks of different thicknesses and also provides for wear of the blank, while at the same time f communicates the necessary traversing moveenabling the recorder and reproducer alwaysv to be. properly positioned to fulfil their respective functions.

It will be understood that the recorder and reproducer may be removable and may be .separately carried upon the machine when required respectively for recording and reproducing, but for convenience we prefer to carry both simultaneously upon the machine and provide means for throwing the one not required at the time out of action.

One method of attaining this object is shown in Fig. 2 according to which there is fitted to the socket of the tone arm p a. fitting s upon a tubular extension t to which the recording horn u (Fig. 6) is mounted, the fitting having a second tubular extension v provided with an aperture 'w and mounted within an outer rotatable sleeve carrying the recorder and repoducer. The arrangement is such that the sleeve may be rotated about a vertical axis through 180, and the recorder and reproducer may be raised or lowered slightly by means ofthe spring arms or levers 4 which are provided each witha recessed end adapted to be engaged with one or the other of a pair of studs 5 in order to hold the recorder or reproducer in its raised position, so that either may be brought into position for operation and in register with the aperture w communicating with the interior of the fitting s in such a manner as to communicate with the recording` horn or. with the amplifying horn or usual way with the tone arm p. When the recorder is thrown out of operation a plug z may be introduced into the tubular extension t to cut out the recording horn.

It will be seen that with such an arrangement as that above described not only will the weight of the device carij'ing the recorder and reproducer be adequately supported sothat the tone arm with its added weight may be employed for reproduction through the amplifying horn or chamber without fear of damage to the record, but also the necessary movement may -be permitted to the recorder or reproducer and owing to the combined movement of the device along the bar m and of the bar m along t-he carrier f, reproduction and recording take place along an are ofthe same dimensions yin relation to the turntable.

Figs. 6 and 7 illustrate a modified form of arrangement 'which is suitable for use when the recorder and reproducer are to be carried separately upon the machine and not as above described simultaneously upon the machine and provided with means for rendering either inoperative as desired. In this case the fitting .s is .of somewhat similar form to that above described with the exception that it has no movable sleeve on the lower extension. The latter is curved orv otherwise suitably formed to carry the reproducer r or the recorder g. The record.- ing horn u may be made to be reversible so that it may. either occupy the position shown in Fig. 6 or that shown in Fig. 8, reproduction in the latter case taking place partly through the recording horn or medium and partly through the amplifying horn or chamber while, as before, a suitable stop may be inserted in the upper portion t of the fitting s when reproduction is to takeplace through the amplifying horn or chamber alone.

When clearing the machine orv for other reasons it is desirable that the carrier f should be raised so that the shaft z' may be disengaged from the socket d and the whole rotated about the axis of the pillar c, and for this purpose a suitable arrangement is shown in F igs. 1 and 11 in which the pillar c is surrounded by a sleeve'l having a bayonet or angle socket 2 engaging a stop or projection 3 upon the pillar, so that when the device is in the position shown in Fig. 1 the stop will be in the lowest portion of the socket 2, while whenthe device is required to be moved out of the way it may be raised so 'that the stop comes on a level with the horizontal portion of the slot ywhich thus permits of the rotation of the whole device about the axis ofthe pillarc through an angh of or of any other desired magnitu e.

Fig. 12 shows a modification in ,accord-V ance w1th the invention having the same general 'features as those above referred to but with a modified form of reproducer.

Having now described our invention what We claim as new and desire to secure by lietters Patent is l.
