To all whom z'tma concern:

Be it known t at l', JOHN C. ENGLISH, a citizen of the United States, and a resident of the city of Camden, county of Camden, and State of New Jersey, have invented certain neu.r and useful Improvements in Sound-Reproducing Machines, of which the following is a fpll, clear, and exact description, reference being had ing drawings, forming part of this specilication.

The main objects of this invent-ion are, to providea compact talking machine having actuating mechanism, and sound reproducing and `sound 'amplifying mechanism inclosed within a casing; to provide a talking machine having sound reproducingimechanisin, and` a sound amplifier inclosed .in a casing having an' improved adjustable cover arranged to receive the sound waves delivered from the sound amplifier and to defleet the same in any desired direction; to provide a talking machine having a record support mounted within a casing', sound reproducing means and sound amplifying` means arranged to coperate with the record support, and supported within the casing from the rear wall thereof, the sound amplifying means having a delivery end opening upwardly beneath the plane of the record support; to provide a talking machine having a casing provided with an adjustable cover and improved` means for holding thc cover in adjusted iosition; to pro vide a talking machine having a casing pro vided with a movable cover, and improved means for preventing the sudden closing rif the cover; to provide a talking machine having a lcasing recessed internally to permit-of the use of a relatively large record; and to provide other improvements as will appear hereinafter.

In the drawings, Figure 1 is a fragmentary side elevation partly in vertical section of a, talking machine constructed in accordance with this invention; and Fig. 2 a transverse vertical Section on line 2)2 of Fig. 1, looking in the direction of @he arrows.

Referring to the drawings, one embodiment of this invention compri-ses a casing or cabinet consisting of a rectangular body portion 1, havinofront and rear walls 2, side walls 3, and ttom wall 4, and an adjustable cover 5, which is pivoted at its to. the accompany l rear edge to the upper rear edge 0I tue rear end Wall Q of the body of the. casing upon hinges 6. The body of the casing is preferably provided on its under side with suitable su ports-7.

7Vithin the body portion of the casing and near the top thereof is a' horizontal re:- i'novable partition 8,`which forms a support for a turntable 9, whichis adapted to carry theusual sound record V10. Beneath the horizontal partition 8 and carried thereby within the casing, is arranged suitable actuating mechanism for rotating the turntable. Although in the present instance, al turntable carrying a disk record is shown within the casing, it is obvious that any other form of record support carrying a Ysuitable record might be used in applying this invention.

` A sound box l or sound reproducing device of any well known construction, is mounted upon and communicates with a U shaped tube 1G, which is pivoted upon a horizontal axis to, and communicates with the free end of a tapering tubular sound box arm 17, which extends rearwardly in :i

substantially horizontal direction, and the` rear end of which is turned downwardlyr and is mounted in any suitable manner to swing upon a fixed vertical axis upon the upper end ofka downwardly extending rigidi tubular brac et 18, with which it communicates.

The tubular bracket 18 forms an intermediate section of a taperimgr sound amplifier, the inner section or inlet end of which is formed by the tapering sound box arm 17. The lower portion of the hollow bracket 1S is curved forwardly and then upwardly forming a return bend or elbow 2 and terminates in an upwardly extending Haring socket 2l, adapted to receive the body portion 22 of the amplifier. The hollow bracket 18 may be substantially uniform in diameter measured in a direction parallel to thesides of the casing. flaring eligzhtlir toward the socket 2l but measured in a dreotion parallel to the rear of the casing. the bracket preferably flares or increases in dimieter from its inner or upper end out wardly as shown in Fig. 2. The hollow bracket is preferably substantially,cylndr- 'cal at its inner end, but it changes gradually to an oblong shape in cross section as it ap preaches the socket 21, which is preferably rectangular and oblong in cross. section, having its long diameter substantially parallel to the rear wall of the casing.

For securing the hollow bracket 18 rigidly in position, the bracket is provided upon its rear side, intermediate of its ends, with oppositely extending flattened pro]ections 25, forming a base plate having a flat rear side which rests against the inner surface of the rear wall 2 of the casing, and is held .in position by bolts 26 which pass through suitable apertures 27 `provided therefor in the opposite sides of the base and in the rear wall of the casing, the bolts having heads integral therewith upon their innerends, and nuts 28, threaded upon their outer ends outside of and in the rear of the easing. Ihe nuts 28 are preferably provided with knurled heads for convenience of manipulation. Any other suitable means, however, obvionslymay be used, instead of or in addition to the means described for rigidly securing the bracket 18 to the rear wall 2 of the casing. In the constructionshown the base plate formed by the projections 25 forms the sole support for the hollow bracket 18, which in turn forms the sole support for the swinging sound box arm at one end of the bracket, and the body portion 22,of the amplifier at the other end of the bracket in the socket 21, these parts being preferably out of contact with any part of the casing except through the base plate.

For rotatably connecting the downwardly extending end of the tubular sound box arm 17 to the upper end of the bracket 18, the upper end of the bracket is enlarged as at 30, and is provided with an internal cylindrical recess 31 opening upwardly. Within the cylindrical recs 31 fits the reduced lower end of a cylindrical head 32, to the upper end of which is secured a flat circular cover 33 by means of screws 34. The cover 33 is provided with a central circular aper- .ture 35 within which rotatably fits the lower end of the sound box arm, the end of the sound box arm projecting downwardly within the head and into proximity to the lower reduced end thereof. The portion of the sound boxv arm within the head is surrounded by a sleeve 36, fixed thereon and provided adjacent each end thereof' with an outwardly projecting annular flange 37, the upper flange forming with the internal surfaces of the cover and side wall of the head a race way for antifriction balls 38, and the lower flange forming with an internal annular shoulder 39 provided within the head. a race way for antifriction balls 40, whereby the sound box arm is rotatably supported. For holding the head 32 in position in the upper end of the bracket 18, a set screw 41 is threaded into the rear side of the upper enlarged end of the bracket and engages against the reduced portion of the head within the bracket, the outer. end o f the screw being preferably provided with a slotted head adapted to be engaged by a screw-driver, and the rear wall of the casing being provided with an aperture 42lfor the convenient insertion of the screw-driver for the adjustment of the screw from the outside of the casing.

To economize space, the bottom Ik of the casing is provided with anA aperture l5 bounded by an inwardly flaring wall, and the elbow 20 of the hollow bracket 18 pro jects within this aperture, but preferably is out of contact withthe flaring wall thereof, although very close thereto, to prevent the escape of sound waves between the elbow and the wall of the aperture.

The body 22 of the amplifier extends upwardly from the socket 21 at the lower. end of the hollow bracket 18, and is entirely supported thereby, and comprises a series of upwardly extending fiat sounding boards 50, substantially semi-circular in shape and having their curved edges inserted within the socket 21, and their straight edges arranged in a substantially horizontal plane, spaced slightly below the plane of the turntable and substantially in the plane of the upper surface of the horizontal partition 8. The rear edge of the horizontal partition 8 is spaced slightly in front of the upper end of the body of the amplifier to permit of the free vibration thereof'. i

The lower edges of the outer sounding boards of the body of the amplifier bear against circular internal shoulders 51 formed against the inner surfaces of the transverse sides of the socket. The inner surfaces of the hollow bracket adjacent the socket, and the inner surfaces of the outer sounding boards are flush with the adjacent inner surfaces of the bracket` and the intermediate sounding boards are sharpened at their lower edges as at 52. to avoid obstructing the passage of sound waves through the amplifier. The curved edges of the sounding boards are connected together by means of' oppositely extending curved side pieces 5?, each of which extends from within one side of' the socket 21 lo the upper straight edges of' the sounding boards and forms a dcflectoi for the sound waves passing through the aiuplifier.- The body of' the amplifier is preferably constructed so that the sounding boards diverge upwardly. although good results may be obtained when the sounding boards are substantially parallel. i

'l`he upper o delivery end of the body 22 of the amplifier is, in the construction shown, oblong and substantially rectangular in shape and has its long diameter substantially parallel with the back of the casing and extends substantially the full width of the interior of the casing, the body of the amplifier, however, being preferably out of y wa rd ly from the contact with any part of the casing, and unrestrained except at its lower end, Where it engages in the socket.

The cover of the casing comprises a top wall 55, having a flat inner surface 56, which is substantially horizontal when the cover is closed, and four downwardly `flaring side walls having fiat inner surfaces 58, which are each arranged preferably at an angle of substantially 45 degrees with the inner surface of the top of the cover so that when the cover is opened to en angle of about 45 degrees with the top plane of the body of the casing. the inner surface ofthe front side of the cover will he substantially horizontal and the inner surface ofthe rear wall of the cover will substantially vertical. T he cover is thus constructed so that its inner surface may act effectively as a reflector to deflect forwardly the sound waves issuing upwardly from thc delivery end of the amplifier and the particular shape shownfor the inner surface of the cover 'is obviously only one of several shapes which are desirable for this purpose.

For holding the cover 5 in any desired position of angularity with respect to the body of the casing, a downwardly extending link 60 is pivoted at its upper end to the inner surface of one side of the cover as at' 61, and the lower end of the link extends slidably through .a suitable slot 62 provided therefor in one side of the horizontal partition 8 and bears slidably against the pin or lug 63, which projects from the horizontal partition and across the rear of the slot. A cam lever 4 is pivoted as at 65 intermediate its ends in a slot provided the'refor in the horizontal partition 8 and in front of the link 60. The rear end of the lever normally engages slidahly against the forward edge of the link and prevents the link from moving downwardly hut does not oil'er any resistance to the upward movement of the link, and the other end 67 of the lever `normally projects downwardly and forwardly in the slot, the lever being normally held in engagement with `the link hy means'of a spiral spring 68 or other suitable yielding connection hetween thelower cud (i7 of thc lcvcr and one side of the casing or other fixed support. For moving the lowcr end of the cam levcr inwardly to bring the other end of thc cam lever out of engagement with thc lilik (i0. a push l'od 69 is pivotcd nl one end to the lower 'end of the lever and extends forwardly therefrom in a substantially horizontal direction in a recess provided therefor upon the under side of thc partition R. andI through the front wall of the casing. the outcr end of the push rod projecting for- Front sidc of the casing! and hcing Iirovidcd with u push button T0 for thc con venienl operation of the rod.

lith this construction in mind, it is oblicr. |mrticularly the `vious that to open the casing, it is simply necessary to raise the cover 5, and the same will be held automatically in any position to which it is moved, and that to close the, casing it is simply necessary to push the hut` 70 ton 70, whereupon the rod 69 will move the cam lever 64 out of engagement with theY link 60, and the lever will then be free to fall into a closed position. The position of the cover 5 when open and the corresponding position 7 5 of the cam lever 64 are shown in dotted lines in F ig. 1.

For preventing the cover from closing suddenly upon the body of the casing when released by the movement of the 'push llut- 30 ton 70, a verticali)4 arranged dash pot T5 of any suitable construction is located within the rear portion of the casing adjacent the bottom thereof. and is pivoted at its lower end to the upper surface of thc hottom of the g5 casing or other fixed support. This dash pot carries the usual piston 76 mount- -ed upon the end of a piston rod 77, and the upper end of the rod is pivotally connected through a. bracket 78 to the rear portion of 90 the inner surface of one side of fthe cover of the casing. When the cover is released from the elevated position the dash pot acts in a well known manner to permit the covcr to fall gently into a closed position upon the body of the casing.

To adapt the machine to use a ."elatively large record, the turntable may llel arranged so that its upper surface is slightly above the upper surface of thc body of thc casing, and the turntable may lic of such a diameter and so placed that the front portion of its peripheral edge is in close proximity to the inner surface of thc from side of the Casing. and so that the rca r portion of its peripheral edge overhangs the front portion of the delivery end of thc :ilnpliher- To permit of the use of u record larger in diameter than the turntahlc, thc lowcr edge of the front side of thc cover is providcd with an internal recess so, :ula'ptcd to rcceivc the projecting edge ol' a record support when placed upon the turntnhlc. thc walls of the recess living out'of contact with thc l'ccord lo permit ofthe frcc rotation ol the record.

ln thc construction allovc described. the shape and urrangcnunt of thc mnplifvng means together with the uniuuc construction of lhc casing mates it possible to provide a talking nuichinc having an amplilicr of rel- 120 ativcly large proportionsI incloscd in a relutivcly shallow and compact casing. and moreover the improved form of thc ampliform of the return y hond or clllow of thc intermediair: or fixed 1;., portion of the amplifier. imparts an improved quality to thc rcproductif'in.

Although in thc. construction illustrated a tapering swinging sound hox arm is shown,` it is obvious that a cylindrical 13o sound box arm might be used instead of the tapering arm, and in this case, the sound box arm might not be considered as a portion of the amplifier, and the amplifier would then consist of the tapering tubular bracket 18 and the resonant body portion 22 carried thereby. It is also obvious that various other changes mi ht be made in the construction illustrate and that the improvements described herein might be used in various relations other thanrthose shown, without departing from the spirit of this invention or the scope of the appended claims.

Having thus described my invention what I claim and desire to protect by Letters Patent of the United States is:
