Be it known that I, HENRY H. MURRAY, a citizen of the United States, and a resident of Riverton, county of Burlington and State of New Jersey, have invented. certain new andA useful Improvements in Stop Mechanisms for Talking-Machines, of whichV the following is a specification.

Une object `of thisinventlion is'to provide in 'a talking machine improved automatic means for stopping the same; and more specifically to provide in a talking machine including a rotary record support,'an\electric motor for actuating the same, and sound reproducing means arranged to coperate with a record on the support, a switch for controlling the motor, a brake for stopping the record support, automatic means controlled by a relative movement between the sound reproducingmeans and a record on 'the support adjustable to actua-'te the switch and the brake to stop the motor and the record support upon the completion of the reproduction of the sounds recorded von the record, and secondary automatic `means actuated by the motor independently of the position of the sound ,reproducing means, to actuate the switch and the brake after the motor has been in operation for 'appredeter-mined period, slightly greater than would be required to reproduce the sounds from the largest `record for which the machine :is designed, to vprevent the motor from being unintentionally operated through' an indefinite period.4

.Further objects of this invention will apf pear hereinafter.

In the accompanying drawings, Figure 1 is' a fragmentary to-pv plan view of a talking `machine constructed in accordance with this inventiomwith the parts shown as they appear atA the beginning of the operation of of the reproduction of sound from the recy ord, and after the operation of the machine has been stopped automatically by the move- Specicatiun ofletters Patent.

and Fig. 9 afragmentary top plan view of the secondary stopping means.v

Referring to the drawings, one embodi-l ment of thisv invention comprises a talking'.

machine i/ncludingthe usual or any suitable cabinet providing'a flat horizontal partition or support 10,`spaced above which is a horif Zontal rotary disk record support 11, adapted tocarry the usual orany suitable disk sound record l2, the record shown being provided on its upper surface with a spiral sound groove 13 of uniform depth and in v the form of lateral undulations correspondingto sound waves. The record support 11 Vis provided With a .marginal -cylindrical flange or rim 14 dependingtherefrom and integral or otherwise rigid therewith, for a pur-.pose that will appear hereinafter. The record support is carried by the upper end of a rotary spindle 15, which projects upwardly freely through an aperture 16 provided therefor in the support 10. The spindle 15 is mounted to rotate about a fixed vertical axis coincident with its longitudinal axis in suitable bearings depending from a rigid motor support 17 arranged beneath and secured to the horizontal support 10.

For rotating the record support 11, an electric motor 20 is arranged beneath the horizontal support 10 and is rigidly secured to the motor support 17 in any suitable manminally connected by any suitable coupling movement in any suitable manner.

mounted upon or integral with the spindle I 22 with a horizontal driving spindle 23 in alinement therewith, and which is mounted to rotate about a fixed horizontal axis `in suitable hearings 24, and 25, depending from and rigid with the motor frame 17, the

spindle 23 being held against longitudinal Rigidly v28 and coaxial therewith is a worm 26 which engages a worin gear 27 rigid and coaxial with thevertical spindle 15, whereby the spindle 15' is rotated to rotate the record support.

Mounted upon the horizntal spindle 23 is a governor including balls 28 carried by springs 29, securedvto a collar 30 fixed on the driving spindle4 23, and to a sleeve 31 slidable longitudinally of the driving spindle 23, and carrying fixed thereon a frictionl` disk 32 which engages va friction pad 33 carried by` anvarm 34 rigid with a shaft 35, which is rotatively adjustable by well known means (not shown) to cause the motor and record support to rotate at a predetermined rate. L

Above the record 12 is the usual or any suitable sound box or sound reproducer 40,

therewith, and to swing across the record 12, the tone arm being supported at its larger end by well known means (not shown) to swing about a' fixed vertical axis.- The sound box 40 is provided with the usual or any suitable stylus 42 arranged to coperate with the sound record 12v by engagement'in the undulatory sound groove 13 for propelling thel sound box'A across the record to re'- produce the sounds' recorded upon the. record.A

Forl starting or stoppingl the 'rotation of the record support 11, and the record 12 carried thereby, automatic means are provided which are preferably arranged mainly 'upon the upper surface of the horizontal partition or support` 10 and beneath the rotaryvrecord support 11 and comprising .a substantially flat horizontal base plate 45 which is rigidly secured by means of screws- 46 lor otherwise'to the upper surfacejof the horizontal supportlO, the major portion of l the base plate being beneath the record sup'- vport 12, but one edge of the base plate rojecting slightly laterally" outwardly rom the margin of the record support as at 47 in order to display the words on and ,oif pr other suitable lettering which may be impressed Ainto the upper surface of lthis A L projecting portion of the base plateV for a purpose which will appear hereinafter.`Vv

Arranged slightly above the base plate is a switch and brake lever 48which is mounted to oscillate about a fixed /vertical pivot 49 extending snugly through an aperture provided therefor in the base plate, a washer 50 being preferably interposed around the pivot 49 between and in contact with the under surface of the switchlever 48 and the upper surface of the baseiplate 45, and the pivot 49 beingpreferably'provided above the switch lever with a head 51 having a fiat under surface which engages against the upper .surface of the switch lever to hold the switch lever rotatably Ain position. The switch lever 48 extends from the pivot 49 outwardly beneath the marginal flange 14 of the record support, and terminates in an upwardly oi-set portion extending outwardly from the pivot 57, the lower end of which is rigidly v secured to the base plate 45, and the upper endof which is provided with a head 58,

vthe lunder surface .of which engages against thevupper end of the sleeve 56 to prevent which is connected to the smaller end .of a.; hollow tapering rtone arm 41 to communicateupward movement of the sleeve. The free end of the `latch 5,5 isA provided with a laterally projecting outwardly tapering tooth .59 arranged .to engage in a correspondingly tapered notch 60 provided therefor in the edge of the switch lever 48 adjalcause the rotation of the record support, as

will appear hereinafter. y

For performing the double function of holding the tooth 59 of the latch 55 in engagementwith the notch 60 of the switch lever 48, and of swinging the switch'lever 48 anti-clockwise from an operative or on to an inoperativeA or oil position, when the latch 55 is released from engagement with the switch lever 48, a spiral spring 65 or other resilient means is secured atv one end to alug 66 projecting upwardly from the `latch' 55, while the other end of the said spring is attached to a lug 67 which -is preferably integral with the switch lever 48. These lugs 66 and 67 are 'so positioned that when the tooth 59 is inengagement with its notch 60, as shown in Fig. 1, the longitudinal axis or line of action of the spiral spring 65 is spaced slightly in front of the tooth V59, and between the tooth 59 and the longitudinal axis of the vertical pivot 49, and -between the tooth 59 and the axis ofoscillation of the latch 55, and ;,axtends ,ina direction nearly radial with respect to the axis of oscillation of the latch 55 1n this position the spring acts to hold the `tooth 59 in enoagement in its notch 60, but by swinging the latch 55 through'a small are anti-'clockwise, the spring will act` edectively to rotate the switch` lever 48 anti-clockwise into an inoperative or off position, as shown in Figs. 2, 3 and 5.` In the latter position the spring 65 acts to hold the rear edge of the free end of the latch 55 lightly in engagement with a fixed stop 68 provided theren i for and projectingupwardly from the base plate 45, and maintains the tooth 59 1n such a position that lonly a slightrotary move,- rnent clockwise is necessary to bring it into operative engagement in its notch 60 after the switchlever has been rotated manually to bring the notchinto alinement with the tooth.

When the tooth 59 is in engagementinits notch 60, it may be released or thrown out of engagement at any time by a slight pressure v anti-clockwise exerted manually or otherwise upon the switch lever 48, in addition to the pull of the spring 65,1theyf-outer side edge of the tooth and the corresponding wall of` the notch being inclined `in a suitable direction to produce this eect, and when the tooth 59 is out of engagement with its notch and in its normal inoperative position, as shownin Figs, `2, 3 and 5, itfmay be broughtinto engagement in the notch simply by manually rotating the switch lever 48 clockwise. The "inner Side edge of the tooth to the switch Yleyer 48,.

59 and the corresponding wall of the notch 6 0 are preferably so shaped as to maintain the tooth in engagement in the notch against any pressure that may be applied clockwise For automatically releasing the latch from"engagement with the switch lever 48 a horizontally extending arm 70 is mounted "at one end to rotate about a vertical axis upon the sleeve 56, and projects from the sleeverearwardly and terminates in the rear of the margin of the record support 11 in a bifurcated end forming two fingers 7"'1 and 72. The inner end of `one,71, of these fingers is arranged to be engaged and actuated by the lower end of a vertical stud-73,.

which is rigidly secured. at its upper `end to` the under side ofthe tapering tone arm 55 41. The other finger 72 of the "arm 70 is preferably provided at its outer end with an upwardly extending stud 74 in the form of a handle for the convenient manual operation or adjustment ofthe arm 70.`

To transmitmotion from the arm 70 to the latchfi, and at the same time to permit 'upper surface of the base plate 45.

stud 73 at Vany desired position, the arm 70 and the latch 55 are preferably yieldingly clamped in a predetermined` relationshlp by means of a 'yielding spl1t washer or U-shapedfspring clip 75, made of spring steel, or other suitable material. The spring clip 75, when in operative position, partially surrounds the sleeve 56,'coaXial-therew1th,

and engages against and istheld in position by the walls of an annular groove 76, providedtherefor in the sleeve 56. This clip 75 isl normally in contact with and. presses downwardly against the upper surface of the corresponding end of thelatch 55, which is preferably arranged above the corresponding end of the arm 70. A washer 77 of beror other suitable material is preferably laced around the sleeve 56, between the a jacent ends of the latch 55 and the arm 70, and a similar washer 78 is interposed around the sleeve 56 and between the under surface of the corresponding end of the arm 70, and an annular flange 79 which projects outwardly from the lower end of the sleeve 56, .preferably integral therewith and the tatedmanually with respect to the sleeve 56,

andthe latch 55, by exerting a force on the handle 74 slightly in excess of the force exerted by the tone arm in coperating with the nger 71 to disengage the tooth 59 from its notch 60. y

For automatically controlling the electric motor 20 there is arranged beneath and depending from the base plate 45 and coaxial with the pivot 49, an electric switch comprising a vflat circular horizontal base 85, of fiber or other insulating material, the upper surface of which is provided centrally with a 'circular recess 86, in which snugly fits the lower end of the vertical pivot 49 of the switch lever 48. The base 85 is surrounded by a suitable vertical cylindrical switch casing 87, whichf may be provided with a suitablewlining S'fof insulating Ina,- terial, and which fits snugly in a cylindrical aperture provided therefor in the horizontal partition 10. The lower end of the casing i 87 `fits snugly ingan annulark marginal recess provided therefor in the upper surface of the circular base, and the base 85 and casing 87 are clamped in xed relationship by means of vertical screws 89 extending 'v ers 105 of insulating material surrounding through i the base and threaded into' the base plate 45.

Within the casing 87 and mounted upon and projecting through the circular base 85, are a pair of stationary brass binding or terminal posts 90 and 91, the upper ends of which are provided with dat rectangularheads 92 and 93, which are held against rotation in rectangular recesses provided therefor in theupper surface of the circullar base 85, and clamped downwardly upon I' the lower portions of two ' brass plates 94 and 95, which are bent upwardly from the heads and then inwardly to form two diametrically opposed stationary horizontal contacts 9G and 97. Stationary brass bushings 98 and 99 may be arranged in recesses provided therefor in the under side of the circular base 85 and surrounding the binding posts 90 and 91 respectively. Surrounding the ixed vertical pivot 49 and within the casing 87 is a rotatable switch member comprising four superimposed plates 100, 101, 102 and 103, each of which is held in fixed relationship with respect to each other by means of two vertical rivets 104, the bottom plate 100 and the top plate 103 fitting snugly but rotatably on the vertical pivot 49 and being spaced and insulated from the intermediate plates 101 and 102 by mea-ns of `washthe rivets 104. The intermediate plates 101 and l102 are clamped together" between the washers 105 and provided with suitable.

against movement longitudinally of the" pivot 49 by means of suitable washers 108 and 109 preferably of insulating material, surrounding the pivot 49 between the top plate 103 and the under surface of the base plate 45, and between the bottom kplate 100 v and the upper surface of the circular base 85 respectively. For rotating the movable contacts 106- and 107 of the switch, the top plate 103 is provided with a vertical extension 110, which projects loosely through a segmental slot 111 in the base plate 45 coaxial with the lvertical pivot 49 and engages in an aperture 112 provided therefor in an extension of the switch lever 48. A iexible electric conductor 115 extends from the binding post 90 to the motor, for supplying the motor with an electric current, anda iexible electric conductor 116 extends from the binding post 91 to a source of electric current. Ay flexible electric return conductor 117 from the motor to the source of electric current completes the motor circuit when the movable contacts 106 and 107 of the I' switch are in engagement with thefstationary contacts 96 and 97.

For stopping the rotation of the record support 11 substantially' at the same time that the switch lever 48 is rotated anti-clockwise either automatically or manually to break the circuit of the motor 20, the switch, l

55 out of engagement with its notch 60, the

brake pad 122 being pressed against the marginal flange 14 when in this position by the action of the spring 65, and the brake pad 122 holding the switchA lever 48 just out of engagement with the free end of the latch 55. g

To prevent the motor from being unintentionally operated through an indefinite period, auxiliary automatic mechanism isprovided, which operates independently of the position of the sound box 'with respect to the record, to release the tooth 59.01? the latch 55 from its notch 60 to break the motor circuit and` to apply the brake after vthe motor has been in operation continuously at any time for a period slightly greater than would be required to reproduce the sounds from the largest record for which the talking machine is designed.

One embodiment of the secondary automatic mechanism comprises a worm 125 coaxial with and rigidly secured to the vertical end of the spindle 15, whichcarries the record support. This worm 125 is preferably arranged beneath and in` engagement with the rigid motor support 17, and en-r gages a corresponding worm gear 126 which is coaxial with and rigidly mounted upon" a horizontal rotary shaft 127, adjacent one end thereof. This shaft 127 is terminally supported in suitable stationary bearings 128 and 129, which depend from and are rigidly secured to the motor support 17, the shaft 127 being heldagainst longitudinal movement tin any suitable manner. The end of the shaft 127 opposite the worm gear'1265is provided with a worm 130 coaxial and rigid therewith which engages a horizontal worm gear 131, which is loosely mounted upon the lower portion and adjacent the lower end of a vertical rol @www tary spindle132, which projects upwardly Y Itherefrom and snuglyvbut rotatablythrough a cylindrical aperture "therefor UPP slightly belowthe un er surface` of the base y' o or bearing provided in'.7 the `motor support 17. y The r end lof the s indie 1132 is spaced late 45 and eixtends4 intol a vertical` clin dr oriu calfaperture 133 provided in the zontal'partition 10. jThe spindle 132 is held ilat "annular Bange 134"integ)ral 0r otherwise rigid therewith' which ....131 lfrictionally, against.` rotation with re- `spect; to its; rotary .spindle 135` while the against upward `movem`ent by means `oi a against the under surface of the motorsup a port 17, `and" is held ,againstu downward movement by. means of` a collar 135, which surrounds the spindle and bears against the npperfsurfaceofgtho support 17, and which is rigidly but detachably secured-fte the spindle by means of a horizontal `pin 136 extending diametricallylthrough Ithe `collar `and, the spindle. y y,

. which engages against the upper side of the bell crank 15'5. Awasher 158 is preferably interposed around thepivot i156 between'the tween the crank Vplate 4151 and theiront edge 'of thclatch 55. Thisbellcranl 155 is` `:nrsmgedr to oscillate about a; fixed vertical ico.

bell crank 155 and theuibase. plate 45,120 holdy the bell crankshghtly above the upper sur,

face of the base plate and in a plane with the crank plate 151. The inner end 159 of the bell crank 155 is arranged to 'normallyenl gage thelfront edge of the latch 55 as at 160,A r

and the frontend 161 of the bell crank is arranged to be always intthe path ofthe beveled-edge 154 fof the lug.y 154 of the "crank plate 151.'` The bell crank 155 haslonly a small amount of free `rotary movement, the

rotation of the bell crank in a clockwise dil rection being` limited vby a' fixed stop 162,' which projects upwardly fromthe rbase plate 45 and preferably integral therewith,-

and which is arranged to engage aside edge of the frontrportion of thek bell crank 155,

and the. rotation ofthe bell crank anti-l clockwise being limited byy the-frontedge of o the latch 55, when the rear ed'geof the latch is in engagement; with its stop l68.

To resetthe crankv plate 151' after `it has .performed leasing the switch lever 48, as'just described, a pushbar 165is mounted toy oscillate about a vertical its function of automatically re-V pivot 166 extending through one l end of 1.the pushgbar andrigidly secured at its i Y from the switch lever lower end to an arm 167 projecting forwardly 166 being provided with' a head 168 bearing against the upper surface of the push bar 165 to hold the push bar slidably in engagement with the upper-surface of the arm 167. l

The inner portion of the push bar is fiat and horizontal and theoutei' portion of the push bar is also iiat andl horizontal but is offset slightlyupwardly from the inner portion so that the under surface of the outer portion is in a horizontal plane slightly above the plane of the upper surface of the bell crank 155 and intersecting the lug 154 of the crank plate. The free' end 169, of the push bar 165 is guided to moveapproXimately in a prede termined pathby means of two fixed lugs 17 3 and 174, spaced upon opposite sides of the push bar 165 and projecting upwardly from the baseplate 45. f

When the switch lever 48 is in an olf position at the limit of the anti-clockwise movement, as shown in Figs. 2, 3, and 5, and when the crank plate 151 is in any position between its extreme inoperative or anticlockwise tion as shown in ter position, the push bar 165 will be moved 1n response to; theclockwise rotation of the by the fixed lugs 173 andy tooth 59 is not in engagenirtjvith its notch 60, but dui-ing the remainderofthe"movement the tooth 59 engages in! its notch 60,

and the notch is made broad eiiough to per-A mit of therotation vof the switch lever anticlockwise through a suitable arc,lwhile the' tooth 59 is in its notch 60 to rotate the crank plate 151 anti-clockwise through an arc equal to the are through which the crank would be rotated clockwise by the operation of the motor 20, through a predetermined period slightly greater than necessary to rel produce the sound from the largest record which the machine is designed to utilize. lVhen the switch lever 48 has been thus ro.-l tated manually, or otherwise', into its eX'- treme clockwise position as shown in Fig. 9,

and is then released, it is returned by 'they its normal action of the spiral spring to l, and the on position as shown in Fig. crank plate is left in` its extreme Wise position or initial inoperative position, thus spacing the free end of the push bar 165 from the lug 154.

riod to reproduce sounds from thelongest Vrecord for which the machine ilsdesigned, Vprovided that meanwhile the automatic release of the switch lever.,48 has not been effected by the engagementlof the stud,73, carried lby the tone arm, with thefinger 7.11ct

When, however, the finger. 71 of th'earm '70 has beenmanually rotated independently lof the latch 55 and set to be engaged by the 'stud 73 of the tone arm coincident l'with of the reproductionof sounds from the be automatically released from an on position just before the beveled edge 154. of the lug 1j`54 of the crank plate 151 has been brought in to contact with the front end 16,1101 the bell crank 155, as shown in Fig.

' ,In any case, after the crank plate 151 has been rotated clockwise from its predetermined eXtreme anti-clockwise position by the continuous operation of the motor 20 Vfor i any given period within the, prescribed limit, it is evident that the crank plate 151 will be reset into its extreme anti-clockwise the switch lever 48 clockposition to a position at the opposite end of its path of motion, the spindle 132 being permitted to rotate anticlockwise `independently of its Worm ygear 131 through the yielding action of the spring clip 138 in coperation with the liber washer 137, which is provided to permit of position by movlnf this rotation or adjustment of the spindle 132 with respect to the worm gear 131, as hereinbefore described. v' While this invention has been shown as 'applied in a talking machine in which the rotary record support is driven at a constant angular rate of rotation by a constant speed motor, 1t 1s evident that the invention might record, the switch lever 48 Y also. Vbe applied to a talking machine in which the record support is driven at a constantly varying angular rate of rotation,.either by a motor actuatedat a constantly varying speed or by a motor actuated at-a constant speed and connected'to the record support bysuitable transmission means, to pro uce a constant surface speed of thefrecord atzthe44 oint of engagement of the record by the sty us. v

Although only a single form has been shown in which thisinvention may be embodied, it is evident that the invention is not limited in its applicaton ltjtlie specific construction illustrated, but ight be embodied in various other forms without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim and desire to protect by LetteisPatent lofthe United States is:

1. The combination with a rotary member, of a motor 4'for actuating said member, an element arranged to move with respect to said member, means controlled 4by the movement of said element to cause the stoppage of saidrotar'y member, and secondary means automatically actuated inde endently of said element, to stop said mem er.

2. The combination with a rotary member, of a motor for actuating said member, an element arranged to move With respect to said member, means controlled by the movement of said element to cause the stoppage of said rotary member, and secondary means automatically actuated independently of said element, to stop'said member after said motor has been in continuous operation for a predetermined period.
