ion: relates to an automatic poseimen'tioned, which can be readily ap plie'd to-fan ordinary phonogra h without the form of a coile ich is adapted for was larger phonogra h,

for the motor mechanism (not shown) and the frame 2 forthe phonograph mechanism,

the mainshaftfi, the cylinder 4, thefeed-nut' 5, the back-rod" 6, the speaker-arm 7 its lift-lever 8, the reproducer 9 and the recordcylinder 10 mounted on .the main cylinder, are of thefwell known character and form employed" "in phonographs of this type, and

do not constitute any part of the present invention. The long controlling-lever 1 1 is pivoted at apoint intermediateits ends to the connecting-bracket 12 having the flat foot 13 thereon, by means. of which the stop mechanism is referablyattached tothe honograph. his al-z'tachment is made by oosening the screws 14 employed for'fasteni-ng the phonogra h-frame to the case, thenslipping the foot 0 the connecting-bracket under the I base-plate 15 of theirame, after which the screws 14 are tightened, thus clam ing thef0ot 13 of the connecting-bracket etween the base-plate of the frame and the cover 16 of the case and securely and rigidly holdingthe stop mechanism in proper position.- In

this type of phonograph the free end of the 'starting lever 17 protrudes u ward. through the slot 18 in the base-plate o the frame, and the motor mechanism is adapted to be started by moving theend of this lever outward,- that istoward the adjacent end of the frame, and to'be stopped by moving the end of this lever inward toward the middle portion of the frame. The actuating-end 19 of the con trolling-lever is located back of the startinglever and 'on its forward ed e are provided the'recess 20 and the shoul er 21, in which recess and against which shoulder'the starting-leveris adaptedtorest' and to be held when in its open or operative position.

The actuating-spring 22 is preferably. in

c spring with the hook 23 on its outer end adapted to engage the starting-lever and the eye 24 on its inner endby which it is connected with the controllinglever, as by means of the rivet 25. The bend 26 is preferably provided near the actuating end of the controlling-lever to bring the respective parts thereof in the ro er plane, and the actuating-spring is, pre era 1y passed through the aperture 27 in thisbend. It is evident that the tension ofthe actuating spring is slightly diagonal, so that the actuating end of the controlling-lever is drawn forward at the same time the starting-lever is drawn inward, and the starting-lever is thus securely held in the angle of the shoulder in the front edge of the controlling-lever.

The trip-bracket 28 'is preferably formed of a flat plate adapted to rest and slide endwise on the upper side of the trip end of the con trollinglever, with the

ears

29 and 30 formed from the body of the plate and bent downward over the front and back edges of the cont-rolling-lever. The flattened or leaf spring 31 is attachedto the bracket, as by means of the rivet-pin 32 passed through the apertures as 33 in the ears thereof and through the tubular aperture 34 formed in the spring, and the handle 35 is preferably provided on the front end of the rivet-pin. The leaf-spring 31 is adapted to press against the under side of the stop-lever, so that the tripbracket 'can be readily adjusted by fm'cefullysliding it longitudinally along the lever and is then held in any desired position by the frictional contact of the spring.

The rear portion'SG of the trip-bracket extends under and to the rear of the elevated track-bar 37, as the same is formed in this type of phonograph, along which track bar the foot 38 of the speaker-arm is adapted to travel. The indicating finger 39 is formed or attached on the rear end of the tripbracket, and extends upward behind the track-bar and in front of the record-cyliinler, and the point it) of this finger is adapted to be adjusted by a proper movement of the tripbracket to register with the end of the indentations on the record-cylinder, or to any other point with reference to which it is desired to stop the motor mechanism.

For use in the larger phonograph the triplever 41 is preferably formed of strong, stiff wire, and is pivoted to the trip-bracket at a pointbehind the track-bar, whence it extends forward and preferably outward to an angle or bend, as at 42, normally directly under the track-bar, whence it extends directly forward in the path of the depending lift-lever S of the speaker-arm and is doubled upward and backward upon itself, as at 43,

to the upwardly extending end or shoulder H'wlnch normally abuts against the forward face of the track-bar; The trip-lever thus descrilmd is the preferred form when made of wire, but it is evident that this particular construction is not essential for the performance of its proper functions, so long as the lever is provided with an arm, as 43, in the )ath of the lift-lever and a cant-acting shou der, as 44, in abutment with the face of the phonograph frame, which arm and shoulder are eccentric to the axis of the pivot of the lever. for the purposes of this invention, the liftarm need not be distinguished from the speakenarm to which it is pivoted, for they And it will be understood that,-

both travel together and it is immaterial whether the trip-lever is in the path of the one or the other.

In use, when the starting-lever is thrown toward the end of the phonograph into position. for starting the motor mechanism, the actuating end of the cont-rollinglever is drawn forward by the action of the actuating-spring, so that the starting lever is enaged in the recess and against the shoulder formed in the front edge of the controllinglever, and it is likewise held in this position ,while the motor mechanism operates the phonograph mechanism and the re )roducer is moved from the inner towards the outer end of the record-cylinder. When the depending lift-leyer 8 comes in contactwith the arm 43 of the trip-lever, the same is carried outward, and in so doing the shoulder -14 of the trip-lever, being in abutment with the forward face of the track-bar, slides along the same and becomes a movable fulcrum, about which fulcrum the trip-lever is rotated and its pivot is carried or'thrown forward. This forward movement of the pivot of the trip-lever throws the trip-bracket with the trip-end of the controlling-lever forward and the actuating-end of the controlling-lever backward, so that the shoulder in the frontedge thereof is moved laterally out of engagement with the starting-lever. and the actuating-spring then pulls the starting-lever inward and stops the motor mechanism.

The parts of the stop mechanism are so proportioned and positioned that by adjusting the point of the indicating-finger to register with the outer end of the indentations on the recort'l-cylinder the motor mechanism will bestopped when the buttoinarm (not shown) of the reproducer has traveled to the same end of the indentations. It is evident that when the starting-lever is again thrown outward to .the position for starting the motor mechanism, thestop mechanism will be automatically set for another action as before.

Referring to the smaller phonograph illustrated in Sheet 2 of the drawings, the short control]ing-lever 11 is pivotedintermediate its ends to the connecting-bracket 12 having the foot 13*, which foot is adapted to be clamped between the base-plate 15 of the phonograph-frame and the cover 16 of the motor mechanism as described above for the larger phonograph. The actuating-end 19 of the short controlling-leyer is likewise locatedback of the free end of, the startingleverl'i of the motor mechanism ant, l is provided with the recess 20 311th'tll 'sllotlltlcl 21 which are adapted to receive and stop" the starting-lever 17 when the same is thrown outward to the position for starting the motor mechanism.

' The ordinary actuating-spring 22 is pro vided with the hook. 23 adapted to engage 2o r 46, and at theother endto the springqpost' 47 which is formed or attached on the-speed adjusting-lever '48 the motor mechanism-- asaiso the. startingeleverfand the eye 24 in the other end-adapted to-eonneet with the short 545.1" The. actuating-spring 22" therein on the remote" side of its pivot post preferably tensienTof-i the. sprin put the actuatingend-" of the controllingdever slightly forward "when the startingdever inward; 1t.

I I

f 4When'the alternate actuating-spring 22" is employed, the" ordinary" actuating-spring 22! can lie-omitted in the stop mechanism for the smaller hono'graphs without-affecting the essentia operations of the same; for,; when using the short controlling-lever, the

'sprir'ig' between the free end of the startinglever andthe controllingdever is'not'so im-' portant because of the comparatively-short distance between the sto -shoulder 21"? of the controlling-lever an thereof.- When the ordinary actuating spring is not used; the operator readilys'ets t e stop mechanism for action, by using the forefinger ofthe left hand for moving'the actuating end of the controllin -leve r'-forward :at the same time the thumb b the same hand is "used for 'r 'noving the starting-lever ontf' Shard.

Y The track-bar the smaller phonograph is formed integral with the baselate '15 of the-phonograph-frame 2 throng out .its lengthys'o; that -there is no s ace under- *neath the track bar through whlchthe trip-vbracket "and trip -'lever" can extend. For this reason these parts must be formed and located entirely on the forward side of the jitrack-bar. The body of the trip-bracket28, f-the ears 29 and 30., the leaf-spring 31-,-the

rivet-pin 32* and the handle 35 are preferably made the same as orsimilar to the like parts'of the trip bracket'described for use. fyvith -the larger honograpln The indicat-. lDgr-jfinger39,
