To all 'w11 om it may concern:
Be it known that I, EDWIN M. KELLoGo, a citizen of the United States, residing in Moline, in the countyof Reck Island and State of Illinois, have invented certain new and useful Improvements in Phonographs, of
which the following is a specification.
This invention relates to that class of phonographs or machines for recording or reproducing sounds, having a stylus, needle or reproducer point adapted to engage a record, and provided with means for enabling a disk-shaped record to be repeatedly played, or the sounds produced by such a machine to be automatically repeated or reproduced.
The rincipal object of the invention i to provide a simple, economical and eilicient phonograph or machine for recording or reproducing sounds, and a simple and eilicient means for automatically lifting and .moving the stylus, or recording needle in the direction-of the starting point, so asy to euable a record to be repeatedly played without requiring the attention of the operator or the return of the stylus to initial position by the operator, and more particularly to provide means whereby this may be accomplished in such a manner and by mechanisin of such construction as to enable disk or fiat records of unequal or varying lengths to be played successively and repeated in the proper time required for each record, or played but once as desired.
A further object is to produce means for automatically stopping the machine at the proper instant, upon the completion of the playing or reproduction of a record, or of each of a series of records, of unequal, varying, or equal lengths, as the case may be, and means for automatically raising the stylus out of engagement with the record at the ...propen instant, automatically returning the stylus or stylus and tone arm to proper starting position for records of varying or any desired length or dimensions, and lowering the stylus into the proper position to automatically begin at the beginning of a record of any desiredlengtli, all in such a manner as to avoid injury to the record or stylus or other parts of the machine.

tion of the tripping and cam mechanism, for
operating the rock shaft.
In constructing a phonograph or machine for recordingand reproducing sounds and automatically repeating the playing ,or reproduction of records of varying or any desired length, in accordance with my invention and improvements, I provide a phonograph or sound recording and reproducing machine a having a record-supporting and operating mechanism comprising in its construction a rotary record-supporting member or turn table b operatively connected with a driving shaft or spindle c mounted in suitable bearings in the main stationary frame d of a phonograph of an desired ordinary or known form-the sha t c being connected with a suitable source of power, such as a spring-driven'or electric motor e. The motor or'driving mechanism or'operating the shaft c may be of any ordinary iocl iio.
. when desired, at the termination of a record,
end'secured to the arm known or desired form, and it is therefore deemed unnecessary to illustrate the same in detail herein, as the ccnstruction of such motors is well understood by those skilled in the art.
The above elements may consist of parts of a phonograph or sound recording and reproducing instrument of any ordinary, known or desired type such, for instance, as that known as the Victor or that known as the Columbia, 0r other form of phonograph, or sound recording and reproducing instrument or machine. Such a machine, complete and comprising said elements and all of the elements of an ordinary phonograph of any known or desired form is provided, as indicated in the drawings, and includes in its construction a bracket or tonearm support. f in which is pivotally mounted a tone-arm g, with the swinging or free end of which is connected a reproducer l1, having a stylus or reproducer point or needle z' adapted to be moved into and out of engagement with a record of sound waves or phonographic record j, which record may be of any known or desired forni of phonographic record, but which isA here shown in the form of aldisk record supported on the rotary support or turn table b and rotatable with and by the latterin the ordinary and well known manner.
The tone arm g is connected with a horn or other desired known or suitable form of resonant or vibratory body or element for phonographs or sound recording or reproducing instruments, said vibratory element being indicated by the reference letter lc, and being the equivalent of a soundingboard or other resonant body.
In the form of machine shown in Figs. 1, 2, and 4 the stylus is adapted to be raised and lowered by swinging the reproducer upward and downward upon ter or axis Z from the position shown in full lines to the position shown in broken lines in Fig. 1, and without raising or lowering the tone arm g, the stylus may be raised at 'the terminating point-of the record `and returned to initial position and lowered into operative position at the initial end of the record. In order to provide means for enabling this to be done automatically and repeated as manv times as may be desired, and lwith records of any desired or varying lengths, and adapted to enable the rotation of the record to be automatically stopped,
a rock shaft m having a lever arm 'n secured in fixed relation thereto by m ns of a sleeve or socket member o havin a set screw or pin for securing the sleeve 0 in fixed relation to the shaft, is rocki'ngly mounted upon a suitable support which support may be in the form of a fixed stub shaft q having one the pivotal cen.
rection, lang finger 6 f by being inserted' in an opening in said arm in position to support the stub shaft q and the rock shaft lm, and the sleeve 0 in operative position, as shown in Figs. 1 and 4. The stub shaft 1 is held rigidly in position by means of a set screw. 1', and the sleeve o is adapted to rotate or rock with the rock shaft m upon the stub shaft. The lever arm n extends upward and is in engagement with one side of the tone arm g in position to move the tone arm from the position indicated in broken lines in Fig. 4 to the position shown in full lines in said figure or from terminal position, with the stylus at the terminal of the record, to initial position, with the stylus at the initial end of the record.
A lever for raising and lowering the stylus is mounted in a suitable support which, in the type of machine shown in Figs. l and 4 consists of a supporting ring s having a perforated depending lug t. The lever u is pivotally mounted' in this supporting ring which forms a fulcrum for the lever, and a relatively short arm of the lever u designated by the reference letter c extends beneath and in with the reproducer and in position to raise and lower the latter and thereby the stylus when the opposite or relatively long arm of the lever u is swung downward by the rocking of the rock shaft m and the sleeve o, said sleeve o being connected with the end ofthe lever u which is nearest the pivotal center or axis of the tone arm or pivoted supporting member which forms a moving fulcrum for the stylus-lifting lever u, by means of a crank arm w on the sleeve 0 and a chain, cord orsimilar flexible connecting element y which is connected at its lower end with said crank arm and, at the other end, with the lever u. A stop arm .2, mounted on the bracket f serves to limit the movement of the tone arm and stylus in one diis provided with an adjustable screw 2 adapted to engage the tone arm and to be adjusted with accuracy.
The rock-shaft m is provided with an upwardly projecting finger or crank arm 3 and an annular disk or gear wheel 4is mounted concentric with the shaft c upon grooved supporting rollers -see FigsQ and 4- and is provided with a peripheral projecting movable into and out of operating engagement with the finger or crank arm 3 of the rock shaft m. This disk, 4, with its projecting finger is thus adapted to operate thel rock shaft so as to cause the stylus to be raised and lowered and the stylus and tone arm to be returned', automatically, to initial position once for each revolution ofthe disk or gear wheel. The rollers or bearings 5 are journaled on upright bosses 7 which form an integral part or parts of an annular supporting casting 8 having laterally projectingarms 9 forked-or perforated to operative engagement iesV iti
receive securing pins 10 which are mounted in the main frame of the machine and serve to hold the casting 8 and thereby the bearing rollers and the annular rotary disk or gear member 4 in operative position. The disk or gear member 4 is provided with an inner flange which extends into grooves or between flange portions of the bearing rollers as shown in Figs. 2 and 4, and this flange is indicated by reference numeral l1.
On the under side of the gear member 4 and integral therewith rows of gear teeth 12, 13 and 14, are provided, each for a different size of phonographic record to be usedthe outer row1 12 being for use in connection with the longest records, the middle row for` shorter records, and the inner row for those still shorter-and an adjustable pinion 15 is mounted upon a rotary shaft 16 journaled in suitable bearingsl'? upon the main frame, said pinion being so connected With said shaft as to be movable longitudinally of the latter into engagement With the desired row of gear teeth of the gear member 4. |The pinion is operatively connected with the shaft 16 so as to be rotatable with the latter, by means of a slotted sleeve or hub 18 in fixed relation to the pinion and encircling the shaft, and a pin 19 which projects laterally from the shaft and into the slot 20 of said sleeve. The sleeve is provided with indicator or gage marks 21 and the pin 19 is located in the proper position to indicate the relative position of the gear 15 to the rows of gear teeth on the gear member 4 by registering with the corresponding gage or index mark on the sleeve when the gear l5 is in toothed engagement with any row of gear teeth.
T he disk or gear member 4 makes one complete revolution for each time the stylus travels over or`is operated upon by a cornplete phonographic record, and during such complete revolution of the gear member 4 the record and turn table make as many revolutions as there are turns or laps in the complete record, and the shaft c, of course,
' revolves the turn table and record and makes the same number of revolutions that they make during each revolution of the gear member 4 with its finger 6 for operating the shaft m.
ln order to obtain the desired relative movements of the various elements, a gear Inember,-preferably in the form of a spiral gear or flat worm 22 having a spiral tooth or scroll 23 on its flat or horizontal surface, and, by preference, on its under side, and in toothed engagement with a gear or Worm wheel 24 which. is fixed to the shaft 16-is fixed to the upright shaft or spindle c, as shown in Figs. 2, and 4.
In order to provide suitable means for stopping the machine automatically, when desired a brake 25, shown in Figs. 1, 4, and
6, is mounted on and rotatable with the rock shaft m by means of a sleeve 27, which forms gpart of the brake and encircles and is movable longitudinally of the shaft m, and an angular slot 29 in said sleeve has an elongated main portion lying longitudinally of the sleeve and a relatively short slot portion lying at an angle to such elongated main slot portion, and a pin 30 fixed to the shaft m extends into said slot. A compressible spring 31 encircles the rock shaft and has one end in engagement with the end of the sleeve portion of the brake and its other end in engagement with the sleeve 0 already described, and the brake is provided With a leather shoe or disk or turn-table engaging portion 32 which is held out of engagement with the turn table when the pin 30 is in the relatively short or transverse portion of the slot, as shown in Fig. 6/ The brake 25 is obviously adapted to be rotated with respect to the rod m from the position shown in Fig. 6 into position to permit the pin 30 to extend into the main relatively long portion of the slot 29. The brake 25 With the slot 29 is thus permitted to be moved longitudinally of the rod m by the spring 31 from the position shownr in Fig. 1 into position to extend beneath the edge of the turn table so as to come into contact with the latter when the shaft m is rotated or rocked by the finger 6 coming into contact with the linger 3 of the shaft m. 1
In operation, the shaft c is rotated by the motor, and turns with and causes the rotation of the turn table and the phonographic record thereon, and the scroll or spiral toothed gear member 22 fixed to the shaft c causes the gear 24, shaft 16 and gear 15 to rotate a distance corresponding with the rotation of the gear or pinion 24 one tooth 'for each complete revolution of the scroll 22 or the shaft 'c and record. IThe continued rotation of the shaft c and gear member or Worm 22 will thus cause the disk 4 to make one complete revolution and operate the rock shaft m by causing the finger 6 to come into contact with the finger 3 on said shaft m, thereby causing the arm w on the sleeve o to operate the lever u and raise the stylus out of engagement with the record, and immediately following the initial upward movement of the stylus, causing the arm or lever n to contact the tone-arm or stylus-lifting lever support and move the tone arm and stylus to initial position so that the stylus will be permitted to descend sufficiently slowly to initial position in engagement with the record at the initial end thereof, as soon as the cam 47 moves over and out of engar.- ment with the finger 3 so as to permit the arm v of the lever u to move downvvamv with the stylus or reproducer. To 'pefmit the above described operation or mo vement of parts'the brakeshould be in the position center corresponding with shownin Figs.` 1,2 and6.. When thefbrake is. released so as to be movedinto operative position beneath theturn tableby the -s ring 31,-it is obvious that: itwill engage.. an stop the rotation of the turn tablewhen the shaft m is rotated by the finger v6 of the gear member 4, as described.
Fig. 2 will serve as anillustration and is an illustration of the construction and arrangement of the elements of the machine shown in Fig. 6, or ofthe construction and arrangement of the elements shown in Fig. 2,'as applied to the type of machine shown in Fig. 6. However, 1n the type of machine shown in Fig. 6, the tone-arm 33 isadapted to swing upward and downward onthe axial the position of the trunnion or pivot 34 in the collar or socket member 35 of the-bracket or arm 36 which corresponds with the bracket or arm fin Fig. 1. Itis, pivotaliy connect the reproducer with the tone-arm, as in the type of machine shown in Fig. 1, and a pivoted lever-supporting arm 34 is mounted with its pivotal center or'axis in line with thc axis of the tone arm of the'leVer-supporting arm 33,- and in positionA to swing in a horizontal plane. The swinging end of the arm 34 is operatively connected with the tone arm 33 by means of a yoke or similar element 37 supported by the pivoted arm and forming an" alining member between the tone arm and the pivoted arm 34 adapted to cause them to swing together when either is swung in a horizontal plane, but to permit the tone arm to be raised at its swinging end with respect to the arm 34 from the position shown in full lines to the position shown in broken lines in Fig. 6, to raiseand lower the reproducer 38, and, thereby, the stylus 39.. To provide for this, the upwardly -projecting arms of the yoke 37 extend on opposite sides of and in engagement with the tone arm, as shown in Figs. .6 and'?. A depending portionV 40 of the-yoke 37, and a pivot pin 41 serve to'pivot'ally connect a stylus-lifting lever 42 with' the swinging end 34, so that the arm 34 with the yoke member and. the pivot 41 form a fulcrum for the lever.-
. The arm of the lever- 42 which is nearest the axis of the arm-34 and between the fulcrum andthe pivvte'dl end of said arm 34 is connected with the crank arm 'w on the sleeve or hollow shaft o which is connected with the rock-shaft m in described in connection with Figs. 1, 2, and 4. For this purpose a flexible element or chain y is'fsecuredat one end to the lever 42 by means of a hook 43, and atitsopposite end, to the lever w. The opposite end of the leverj42 consists ofa lever arm,44 whih'extends beneath and in position to engag'feand support the reproducer 38, to raise;I -and therefore, not necessary tov the manner alreadyA lower vthe .stylus 39 inethe mannersu ggested bythe-description ofthe elements: shown in theother. iguresof'thc drawings. T-hetonef arm33 .and stylus 39 are vthus provided with means for raising andlowering them, and. for automatically swinging them from their positionsvwhen the terminal of a record is reached, back to initial position, in substantiallythe same manner already describedin connection with the same or similar elements.
The functions ofthe elements shown in Fig. 6, `and their mode of operation being obvious in view of the foregoing description ofthe mechanism inconnection with the othersfigures of the drawings, further description is believed to be unnecessary, as the description of the parts shown in the otherfigures and not shown in Fig. 6 applies inall respects to the machine which is shown in Fig. 6, and which contains all of theelementsshown in Figs. 2 and 5.
From the foregoing it will be seen that the sound box or reproducer h, the tone-arm, and the stylus-lifting lever, in the type of machine shown in Fig. 1 form pivotally mounted stylus-supporting mechanism, and are operatively connected with the stylusthe stylus being connectedat its upper end with the diaphragm 45 of the reproducer or sound box h, and, at a point between the point of connection with the rdiaphragm and the record-engaging point of the stylus or needle, with the soundbox casing, by means ofaconnecting member or pivot 46 adapted to permit the vibration of the stylus and the communication of the vibrations to the diaphragm. In the type of machine shown in Fig. 6 the tone-arm arm 34', reproducer or sound-box h, and the stylus-lifting lever 42 form .pivoted stylussupporting mechanism, and in both forms of themachine or tripping linger 3 and crank arm or upwardly projecting spring arm n forms rocking mechanism for moving the stylus-supporting mechanism from the position which itoccupies at the limit of the movement of the parts in one direction, or with the stylus at the terminal of the record, back to initial position, or' with the stylus ini position to -begin or repeat the playing of a record.
'Ihe actuating gear member'4, with its tripping member 6 always movesthe tripping finger 3 of the rock shaft or reciprocating member m the same distance. llt is therefore necessary that some element between the drive-shaft and the pivoted stylus-supporting mechanism or tone arm, should be of flexible material or yieldingly mounted, in order that records of any desired' length or varying lengths may berepeatedly. played. The arm n is therefore, by preference, 4made in the form of a, spring adapted to yield 33, pivoted supporting' ion maarre when the tone-arm is in position to begin its movement with the stylus at the initial end of a relatively short record, thus pel;- mitting the rock shaft m to be rocked the required distance regardless of the position of the adjustable stop arm z, which stops the tone-arm and thereby the stylus, at the required position for beginning or repeating a record. y
lt is very desirable that means be provided Whereby the stylus will be prevented from coming into contact With the revolving record until the latter has attained a speed which Will enable the sounds to be properly produced, reproduced or repeated, and also to prevent the sudden or too rapid descent of thestylus into its lowered position or into contact with the record. lin order to accomplish this, a projecting portion or shoe 47 is provided, which may be .integral with the rotary actuating member 4 and tripping projection or finger 6. Thisl shoe lor guard is in position to follow the tripping or actuating finger 6 over the tripping linger 3 on the shaft m, Iand is provided with an upwardly and rearwardly inclined bottom surface adapted to engage ^the finger 3 so as to permit the latter to rise gradually to its normal upright or raised position, thereby permitting the gradual lowering of the arm 'v of the stylus-lifting lever u, and the gradual lowering of the sound-box or reproducer and stylus, by force of gravity, after the record-supporting member and record have been in rotation long enough to cause the shoe or guard 47' pass over and in contact with the tripping finger 3, as already suggested.
