WILLIAM D. LA RUE, OF CAMDEN, NEW JERSEY, ASSIGNOR TO VICTOR TALKING MACHINE COMPANY. A CORPORATION OF NEW JERSEY.

To all whom it may concern:

' Be it known that I, WILLIAM D. LA RUE, a citizen of the United States, and a resident of the city of Camden, State of New Jersey, have invented certain new and useful Improv'ements in Talking-Machines, of which the following is a specification.

One object of this invention is to provide in a talkin machine including a cabinet, a turntable or supporting records, a motor for rotating the turntable and a tilting motor support or motor board for supporting the motor and the turntable, and in which the motor support may be conveniently tilted or oscillated to 'swing the motor into a convenient position for lnspection, lubricatio n,'adjustment, or repairs, and whereby the motor-and its support may be quickly and conveniently removed from the cabinet for any desired purpose. r p Further objects 'of this invention are to provide an improved arrangement of the elements of the motor and the parts coop-- crating therewith including sound reproducing means and sound amplifying means; and to provide other improvementsas will ap pear hereinafter.

In the accompanying drawings, Figure 1 is a fra entary vertical central longitudinal sectlon of a talking machine constructed in.accordan'cev with this invention; Fig. 2 iaa topplan view of the same,,but with the covering ofthe 'cabinet removed; Figs. 3 and 4 are an enlarged top lan view and an -35 enlarged-side elevation o a detail of the same'ip'and. Figs. 5; and 6 are an enlarged top {plan view and 'an enlarged side elevation of another detail of'the same. i

Referring, to the drawings, one embodiment of the invention comprises altalking machine'including the usual or any suitable body portion5, substantially rectangular in horlzontal section, and including a front vertieal wall 6, aback or rear vertical wall 7, and two vertical side wa11S,, 8 and 9. Su erimposed upon the body .5 is the usual ho low a cover 11 which is hinged as at 12 to the upper edge of the rear wall 7., Arranged within the bod portion-6 and spacedslightly below t e upperedges thereof is a substantiallyhorizontal fixed partition or support 15. which is rigidly secured to the Specificatiun of Letters Patent.

vertical walls 6, 7, l and-9 of the body 10 of the cabinet.

The partition 15 is providedwith a rectangular and preferably substantially square opening 16 the surrounding edge walls of which are parallel to the vertical walls of the body portion 5 respectively. This opening 16 is normally closed by a flat rectangularmotor support or motor board 17 of substantially the same thickness as and normally arranged in a plane with the partition 15, and is mounted to oscillate about two oppositely disposed ali1 led pivots 18 which are preferably integral with two fiat base plates 19 which are rigidly secured to the under side of the partition'15, by screws 20 or in v pivot bearings 25 aid 26 comprises a flat normally horizontal Jase plate 27' which is recess provided therefor'in the under sur ace of the motor board 1'7, by means 0: screws 28, and is provided with an extension 30 integral therewith which curves downwardly therefrom snugl around the fi out side of the correspon ing pivot 18 in a semircylindrical form and then projects rearwardly in a direction parallel to the base jp late 27 and terminates in the rear'of the pivot. in a downwardly curved end 31. The outer edges of the two 26 arepreferably arranged in vertical alinement with the corresponding side edges of the'motor board 17. The pivots l8 and pivot bearings 25 and 26 are preferably arranged to locate the axis of oscillation of t 1e motorboard, which coincides with the longitudinal axis of the pivots 18, in a line spa ced slightly below the motor board 17 and parallel to-the front and rear edgesthereof and arranged between-the center of the'motor', bo ardand the rear edge thereof, and preferal 1y nearer the center. thanthe rear edge. 'Arrangedcentrally above the motor board creasing its weight' The spindle 36 projects board 17 and downwardly through an aperture 37 provided therefor centrally throughthe motor is arranged to rotate about an axis fixed with respect to the motor board and is held against longitudinal movement in bearings 38 depending from the motor board. I

For rotating the turntable spindle36, a motor 39 is arranged beneath and detachably secured to the motor board 17. The motor shown in this connection includes one or more spring barrels 40 which arranged in the rear of the vertical spindle 36 about a horizontal axis extending transversely of the cabinet and parallel to the front edge of the motor board, and which operate in a well-known manner to rotate the turntable spindle.

The motor'39 is provided with a governor 41 of any well-known fly-ball ty e or suit able constructionwhich is pre erably arranged to be driven from the turntable spindle 36 and to project forwardly therefrom.

The speed of the-turntable may be-adjusted by any well-known or suitable s eed regulating device 42 w ich is prefera 1 located in the front right and corner of t e m'otor board. This re lating device 42 is preferably of the we l-known construction illustrated in the U. S. Patent No. 1,040,522, is. sued October 5th, 19:12, comprising an index plate-43 fixedly clamped against the upper surface of the motor board 17, a rotatable spindle 44 extending through the indexplate and through the pointer 45 secured to the upper end of the spindle to cooperate with theindex plate 43,

a cam '46 longitudinally adjustable on the lower end of the spindle but held against'rotation with respect thereto, and an adjusting screw 47 threaded longitudinally into the lower end of the spindle for'adjusting the cam 46 longitudinally of the spindle, the cam46 being arranged to against the outer -endof a crank arm 48 which actuates 'the' friction pads 48 of the governor 41. It is to be understood, however, that this invention is not limited to the use of any specific speed regulator, as any suitable form may be used,

ement and combination of the specific spee regulator are preferably tor or its governor, V 4 ing bar'50-is-pivotally connected at one end .the front and rear "and adjacent the left vertical motor board, an index' or.

engage 'slidingly although it is evident th-at'by the specific arran with the tilting motor-board the adjustment of the speed regulator by meansof the screw 47 is facilitated.

The arrangement of the parts carried by the motor board 17 is such that the combined weights of-these parts tend to swing' the front edge of the motor board downwardly when the motor board is in a hori zontal position and to swing the front edge of the motor board forwardly and downwardly when the front edge of the motor board is in any position between its normal horizontal position as shown/in. full line in Fig. 1, and an approximately vertical position as shown in dotted lines in Fig. l, or in the latter position. To hold the motor board in itsnormal horizontal position against the action of gravity, a flat horizontal bracket 49 is secured to the under surface ofthe horizontal partition at each of the front corners of the rectangular opening 16 through the partition so as to project beneath the motor board and prevent this front edge from swinging downwardly below the lower horizontal position. A knob 49 may be secured to the upper surface of the front portion of the motor board 17 and preferably'in the front For supporting the motor board in an ap-v proximately vertical osition or in an inverted position slight y inclined upwardly and rearwa rdly from the pivots 18, as shown indotted hn'esin Fig. 1, for convenience in inspecting,lubricating, or adjusting the moa flat elongated supportto a plate5l rigidly secured by two screws 52 to the under surface ofthe motor board at a point approximately midway between edges of the-motor board board; the supporting 'bar 50 being preferablyarranged to sw1n in a substantially plane substant ally parallel to. and spaced sl1ghtly inwardly from the left-hand edge of the motor board. Thesupporting bar 50 extends forwardly from the plate 51 and is provided with, a ngitudinal slot or aperture in which engages a horizontal pin or stop 54 which projects rigidly from a plate 55 rigidly secured'by screws 56 to the under side of the partition 15 the walls of the slot 53 preferabl engagin slidably in an annular groove 5 provider? therefor in the pin 54. The front end of the supporting bar 50 is providedwith an internal re and side of the motor cess '58 which opens downwardly into the 7 slot 53 and which is adapted to receivethe pin 54 to hold the motor-board in approximately vertical position as indicated in dotted lines in Fig. 1. n the. motor board is in the latter position the portion of the motonboard above its pivots 18 tends forwardly over the lifting the front end of the The hollow bracket 66 is provided swing forwardly under the action of gravity but is held against forward movei'nent by the sup rting bar 50, and when in this position til: motor board may be released by and permitting the pin 54. The motor board 17 together with the mosupporting bar to slide I tor 39 may be conveniently removed from the cabinet merely by tilting the motor board into anapproximately vertical position, then disconnecting the supporting bar 50 from the motor board by removing the two screws 52, and then lifting the motor board vertically from the pivots 18, the pivot bearings 2'5 and 26 being so constructed, as .hereinbefore described, to permit of the removal of the motor board in this manner.

v For reproducing and amplifying sounds, a sound box or sound reproducerof any well-known or suitable construction is ar-: ranged above the record support 34 to co 0 rate with a sound record 35 upon the support. This sound box 60 is connected to uni communicates with the outer end of a short tube 61 the other end of which is pivotally connected to and communicates with the smaller end of a tubular tapering sound box arm 62 to swing with respect thereto about ahorizontal axis and tocommunicate therewith The sound box arm 62 extends rearwardly from the sound. box 60 and is pzvotallysuperimposed or mounted upon and carried by the rear portion of the partitrorpld, in awell-known manner, to swing on a. pivot 63in a predetermined substantially horizontal path about a fixed vertical axis which is substantially coincident with the longitudinal axis of the larger end of the sound box arm. Said sound box arm is curved downwardly and communicates through an aperture 64 in the partition 15 with the upper end of a passage 65through a rigid hollow bracket 66 rigidly secured to the under surface of the partition 15.
