-T0 all whom it may concern:

tion Relating to Phonograph-Stop Devices,

of which the following'is a specification,

taken in connection with the accompanying drawing, which forms'part of the same.

This invent-ion relates especiallyjto phono- "graph stopdevices adapted to cooperate with the usual disk phonographs and comprising a brake lever cooperating with the turntable of the machine and having an actuating spring normally holding a pro- "ectin catch on said brakearm in contact with a latch arm which may also be pivoted beneath the turntable and having a part projecting therefrom so as to cooperate with and be actuated by the usual tone arm of the phonograph. An adjuster may be used in connection with the latch arm to regulate the part of the record at which the stop device operates and if desired, a contact arm may be used in connection with the adjuster so as to be engaged by the tone arm and operatethe brake by releasing. thelatch.

In the accompanying drawing showing several illustrative embodiments of this in vention, Figure l is a plan view, parts heingbroken away. Fig. 2 is a side elevation, and F is 3 is an enlarged elevation showing a modified form of the device.

In the embodiment of the invention shown in Figs. 1 and 2 the top 1 of the motor casing may be of any usual construction and the rotating turntable 4 may be mounted above th same in the usual way so as to properly support the phonograph record disk The brake lever 19 may be conreni'ently'pivoted beneath the turntable by securing it by the pivot screw or pin 17 in the top so as to bring the brake 20, of

leather or other suitable material, into cooperation with any conven ent part ofthe phonograph mechanIsnn-such as the depending edge tiangefQ'S o1"? thje tuintable. The

brake .may hare.- a suitable actuating spring 1 5.which maybeconveniently connected to Specification of Letters Patent. Patgnted Application filed Apri1 3, 1912. Serial No. 688,129.

13 which may be conveniently pivotedabout the pivot screw 12 beneath the turntable, suitable metallic washers being used, if de-' thebrake arm 16 and to a cooperating latch sired, below these pivoted parts and also, in

some cases, above them. By arranging this actuating spring substantially in line with the latch it normally holds the same in contact with the latch pin 29 so asto bring the end of this latch into engagementwith any suitable portion of the brake arm such for instance as the upwardly projecting catch lat adjacent the end of the same. In this way the spring powerfully actuates "the brake so as to bring the turntable to rest after a partial revolution which serves-to gradually absorb its momentum while at'the same tune t-hisspring interposes little jre'sist ance to the movement of the latch arn l-away from the catch during this tripping orstop-' ping action. The latch arm ll -is preterably.

extended so as to projectsomewha beyond the turntable and be actuated from the usual tone arm 2 which 1s swung over the record in any usualway.

If desired the stop device may comprise a records in which the sound-groove extends inward to varying dlstan'ces'as is usual. For

this purpose the adjuster 9 may, if desired,

be provided with a wedge shaped end .00- operating with the latch arm andpreferably having fiat edges of about the height. of the.

latch arm, these edges being conveniently formed by stampin or bendingup theedge portions of a fiat giece of metal. This ad-, juster may be connected by the pivot 25 to the adjusting lever 2a which may be mounted so as toswing' aboutthe pivot screw beneath the turntable and have its indlcator by the needle attached togthe sound box 3 suitable adjuster cooperating with the latch arm in such way as to regulate't-he' part of; the record at which the'stop" device is actu- "ated, and thus make the device adaptable to and handle 26 cooperate with a suitable graduated scale 27'located at a convenient distance beyond the 'edgeof the turntable,

and preferably on the opposite side of the axis of the turntable from the. adjustingleverv pivot 23 so that the lever end moves substantially symmetrically over this scale. A

stop pin 22 may be used to limitthe move-' mentof the adjusting lever and a suitable stop pin 10 may be used to prevent the adjuster from moving away from the latch arm to anundesirable extent.

If desired a suitable contact arm 7 may be mounted in any desired way for cooperation with the tone arm and the other parts to be actuated therefrom, and this contact arm may if desired, be pivoted about the pivot screw 12 of the catch and be provided with a contact piece 6 projecting upward into the path of the tone arm itself so as to disengage the latch by swinging the latch arm and inw terposed adjuster over when the tone arm engages the contact piece, the contact arm, of course, having in this case a suitable projection on the underside to engage the ad juster such for example as a short extension of the contact piece or rod 6. The contact arm preferably has a relatively broad pivot-al portion cooperating with the fiat latch so as to minimize twisting when the parts are actuated although a light pressure is sufficient to disengage the latch arm from the catch of the brake arm which thereupon swings the latch inward so as to relieve the contact piece from further pressure from the tone arm, the direction in which the parts move in stopping the turntable, being indicated by the arrows in Fig. 1. The device may be readily reset when the tone arm is swun out into the usual position and a new record applied to the turntable, by forcing the setting handle 21 inward which swings the brake arm outward sufiicient-ly to allow the latch to be swung upward by the actuating spring into contact with the latch pin 29 so that on releasing the setting handle the actuating spring draws thecatch 14L- against the latch so as to disengageably hold these parts in the normal set positions shown in Fig. 1, the brake being thus released from contact with the turntable which thus begins to rotate in the usual way to play the record. I

Since the sound grooves terminate at different distances from the centers of various records it is desirable to indicate on each record the location of the inner end of the sound groove atwhich pointthe stopping device should be actuatedand for this purpose the records may be measured and marked to correspond with the designatmns on the scale :27 which may be arbitrary orinwardly swinging tone arm when the needle contactpiece may directly engage the adjuster as is shown in Fig. 3. In the modification of the device therein indicated the contact arm 30 may be connected to the tone 7 arm 2 by securing the plate on the end of the contact piece to the tone arm in any desired way such as by the screws 32. The contact arm is thus in the path of the aduster 8 so as to engage the same when the tone arm is moved inward to the end of the sound groove so as to force the adjuster and cooperating contact arm 11 over sufiiciently to stop the machine.
