PHONOGRAPH.

To all whom it may concern:

Be it known that 1, WILLIAM W. ROSEN- FIELD, a citizen of the United States, residing courity, and State of New York, have invented an Improvement in Phofiogra'phs, of. which the following is a specification.

This invention relates to automatically Til: invention has been made especially actuated phonograph to operate to make successive productions of a record or records. To this end I provide means for automatically graph is given its reproducing, movements, and means for automatically raising the reproducer from the record and for returning the parts to normal or starting position. For re-winding the spring motor, 1 preferably rovide an electriemotor and means wherethe circuit is closed to such electric motor to cause the re-winding of the spring motor preferably after the reproduction of a record, and the electric motor also preferably actuates the automatic return mechanism.

Phonographs operated by spring motors are now incommon use, but other forms of stored-power motors might be employed for directly actuating phonographs for their reproducing movements, and this invention, so far as it relates to the feature of automatic l ally re-winding or otherwise storing power in an actuating motor of a phonogra h. considered broadly, s not to be limitc to any In the drawings Figure 1 is an elevationactuated phonograph of well known form provided with rewinding and return mechanism in accordance with my present invention. Fig. 3 is an elevation of parts of the operating mechanism looking from the hack Fig. 4 is a transverse section and elevation at the ootted line 2;, a, of

The eccentric or cam disk 9 is provided "with a notched hub y, and has secured to its face a weight-plate 6, and its periphery is formed with a notch or low portion 7, with upon a shaft of the train of gears a toothed portion 5 beyond the low portion 7 and extending to a high portion, with a tail-rib it beyond the toothed portion, and with a portion 10 which is smootln, Pivotally connected to the bracket-arm b is a latch ll having a tooth 1-1 for engaging the notch in the hub g, said latch llbeing weighted or m'er-lndanced by reason of the position of its pivot I! so that its tooth 11 normally bears against the hub g. Said arm also has an end 12 on the other side of the pivot from the tooth 11 for engaging a cam rod or arm 13 :tdjustahle longitudinally on a support H secured to the bed a of the phonograph. I A return feed screw 1'. is mounted in bearings 15 upon the bed of thegplionograph. This serve sltnlt prel'ernblv h-..s a spiral groove of course Pllt'll compared with the thread of the feed screw c and is provided I contact with the cam disk s by means of a w th t eth between the convolutimis of the gr Live for a portion of its len th. The shaft of the return feed serew carries fast thereon a sprocket Z represents tht shaftfrom an electric moto positioned vertically, and having at its upper end a wo m Z meshing with-a gear :11 mounted free LO rotate upon ashaft m extending horizontally and having hearings in the sides of a casing 7c. The gear m i ill a gear m and these together 0 upon the shaft 111. The shaft m is driven by the rotation of the gear m thr'uxgzh a siip coupling which will permit :r to slip on the shaft when a certain ance is stirred to the rotation of the shaft. Any suitahie form of friction c0upiing, or driving device, may be provided or this purpose. In the preferred form of iriciion coupling shown, a collar 18 is nmunicd fast on the shaft m at one side of the gears m and m and at the other side of said gears is u coilai 17 also fast on the shaft, white between the collar 17 and the gears is a notched flanged sleev 0* held against rotation relariwiy to the shaft m by a pin. c passing through the shaft andpressed against the {new at the gear m. by a helical spring 19 one end of old-sh bears against the collar 17 an the other end against. the flange of the film-Ye 1'. (Figs. Rand S). The shaft m is continued by means of a coupling shown in Figs. 1 and 3, and terminates in a inion pushing with a gear through whici the spring motor 5 may be rewound.

I. shaft n is mounted above the shaft m in bearings 16. Fast on this shaft a gear 11:? meshing with the gear m also fast on this sin-it is a sprocket- 11', a chain '11. passing around the sp ocket- -n and to and around the sproelr i on the shaft of the return feed screw rotating said shaft. The shaft 'n also has first thereon a pinion n meshing "with gear 0 mounted uponnn arbor o whieh s cured in a. lu oi the casing is. A ram dis s of eonduoting material is mounted to rotate with the gear 0 and is insulated from tne gear 0 and the arbor o by b ing mounted on an insulating disk 1' secured to the gear 0. 1 s )ring conlzu-t arm t for en-' gaging the periplmuv of the cam disk 3 is secured by u binding-post clamp. t to an insulating post fast to a post.

To t )e binding-post (-lam p5 Z and 1 are C(miltlittl wires 20 and 21 espect vely f ilw l'ifmlii to the electric motor. so that in the operation of the machine when the r-n:ii-:-.('i arm 2' engages the cam (li.

' 'lhe ont-wt arm t i: normally held out rocker arm -v pivoted at 22 to a bracket arm k One end of this rocker a: in is provided with an insulating block if adapted to move beneath the contact arm 1 when the latter has been raised by the high point of the cam disk 3, and the rocker arm is under tension of a spring 28 which tends to swing the. rockerarm on its pivot to move the block 1;? toward and beneath the end of the contact arm. The other end of the rocker arm is provided with a foot piece v which lies in the ath of movement of the sleeve f carried the arbor f in position to be. engaged there y as the re reducer arm approaches the end of its repro ucing movement.

T position of the parts as shown in Figs. 1 and 2 is that assumed by them at the end of the reproducing movement of the phonograph preparatory to the return of the reprodncer arm to an initial or original position either to repeat the record or to reproduce from another record. In these li ures the position of the rocker-arm v and the. spring contact-arm tis as represented in Fig. 5, while the position of these parts during tho re reduction of the record and before the 'ar r f and its sleeve f reach the limit of their movement is that re resented Fig. 6- thatis to say with t e insulating-block 1*" moved beneath and sup orting the free end of the spring-arm tin w rich position the electric circuit is broken and the electric motor not running.

As shown in Figs. 1 and 2, the extreme advance movement of the reprodueer-arm and arbor f have brought the end of the sleeve f in contact with the foot-niece o and the rocker-arm 'v has been there y swung on its )ivot to remove the insulating-block o" from beneath the end of the spring-arm t, allow- .ing the same to drop into contact with the periphery of the camrdisk s so as to comdate the electric circuit through the wire .20, binding post clamp t, arm 2!, cam-disk .9, contact spring 1", binding-post clamp 7" and wire 21, thereby starting the electric motor. The insulating block 2: is then held against the side of the arm 2 by the action of the s :ring 23 until the arm t is again raised by the (am disk 8 to permit the block if to again move beneath the arm 2. The electric motor bein" thus started, the rotation of the shaft Z and worm wheel 1 drives the gears m, m together, and the shaft m is frictionally driven through the friction cou )ling formed by the collars i7 and 18, the sleeve 1" and the spring 19, thereby winding up the spring motor F. Simultuneousythe gear m. causes the rotation of the gear m and the shaft 11, whii'h through he sprorket 72, the (llfiill w: and the sprocket drives the return feed srren' i, and (he shaft 21 [hr-nigh he pinion 1;" also rot-Hes i" s gear and the innit-( I 'z lion-v! am proportioned that tho cam-disk is not given a cuinplvtc rotation until the return fwd;

it the spring motor 0 is allowed to c mtinue in operuuou after the eturn ofthe reproducer arm and the feed nut to operative p sition, the phonograph will be again actuated thereby for again reproducing the record the electric motor meanwhile remaining at rest until the reproducer arm nears the end of its reproducing movement, at which time the sleer f will again engage the foot piece 2" to swing the rocker arm 7; to carry the hloelc 1? from under the contact-arm t and permit the (unmet urn: to spring into contact with the periphery of the cum disk 5-, thereby again closing the circuit. for causing the electric motor in operate 1-.) rewind the spring motor and to rotate the return feed screw for again returning the reproducer arm to its initial or starting position. Evidently, however, suitable means may be provided for stopping the operation of the spring motor before the. return movement of the repr'nhu-er arm has been coin ileted, and when such means is provided the entire mechanism will remain at rest after the return nitwement f the reproducer arm has been Completed and until the spring motor is again put in operation, whereupon the. reproducing and return movements of the phonograph and the rnwinding of the spring niotur will again he etl'ected in order and re peat'ed until the spring un t-or is again sto ped.

further rotation of the return feed produring devices shall operate only overthe length of the actual record, thus avnitle in; waste of time and unnecessary movementot the parts. i

To insure full rcwinding of the spring mOt-or with the longest record which the machine is adapted to reproduce, the amount of rotation given to the worm gearm at each operation of the (-lectrie motor will preferably he more than suflieient to rewind the spring motor t the tmision to which it was w-rnuni before the rum-i 'uceznent of the r -produelz movenut'nl. l'\ z ii}il"-; f between the n rm.

It will be seen that with the construction shown, the return movement of the reciprocating part of the phonograph, that is the reproducer arm in the construct-ion shown, is ell'ected entirely by the power of the electric motor and does not add at all to the work to be performed by and cannot ati'ect the operation of the spring motor.
