rHonoGR ArH.

Application filed December 6, 1922. Serial No. 605,240.

T 0 all whom it may concern:

Be it known that I, WILLIAM T. GAMES, a citizen ofthe United States, residing at Kansas City, in the county of ackson and State of Missouri, have invented certain new and useful Improvements in Phonographs; and I do hereby declare the following to be a full, clear, and exact' description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters .of referencemai'ked thereon, forming part of this specification. a

This invention relates to phonographs of the type in which a number of record-discs can be placed in alsuitable rack or carrier and each record in turn will be placed on the turn-table and revolved, the tone arm swung to position and the needle lowered upon the record; and after the record is played the needle will be raised and the tone-arm swung clear of the record. The record will then be removed from the turn-table and placed in the rack, and another record lifted from the rack and placed on the turn-table; all of which operations will 'be automatic, and continuous until the machine is stopped by shutting off the power.

The features of this invention are hereinafter fully explained and pointed out, and

are illustrated in the accompanying drawings in which:

In these drawings A, see Figs. 1, 6 and 7, indicates the frame of the machine, which is enclosed within the case ofthe machine.

At one side of the machine the frame A is at a lower plane than the rest of the frame, in which are shaft bear-ings A and,

A see Figs. 6 and 7, andmounted in the bearing A is a short shaft B see Fig. 2", which supports a pair of spaced sprocket wheels B. Mounted in the other shaft bearings A is another shaft B upon which is' supported and secured a pair of spaced sprocket wheels B which are opposite and in line with the sprocket wheels B at the other side of the machine. Upon these sprocket wheels is a pair of sprocket chains B The links of these chains are provided with laterall projecting arms I), and I) see Figs. 15 an 16, to which are secured, by rivets or otherwise, segmental cross-bars b see Figs. 1, 2, and 2, there being suflicient space between adjacent bars 6 to receive a record disc I7 and b as shown in Fig. 2.

The arms I) of the chain links are provided with a laterally extending bracket 6 on each side of the carrier, which brackets receive the lower edge of the large sized record discs. The segmental cross-bars secured to the arms 6 on each alternate cham link, are provided with brackets 25 which are secured to the inner surface of the segmental cross-bars see Fig. 14;, and project through openings in the side walls of said bars so that they will engage the lower edge of small. sized records when placed in the carrler. I

The shaft B is also journalled in a downwardly extending art a, of the frame A, and is provided with a. frictionally driven ratchet wheel 0, see Fig. 13, which'is secured on said shaft between the discs C and G with intervening f discs of packing 0 0 between them. The discs C and C are provided with hubs 0' by means of which they are non-rotatably secured to the shaft B by means of transverse pins c and 0 the pin a passing through a slot in the shaft B The end of the shaft B is hollow and is closed by means of a screw-plug C and a s ring 0 is placed between the screw-plug 8 and the pin a, so as to press against said pin and thereby press the disc 0* toward the disc C and thereby compress the layers of packing 0 0 against the ratchet wheel 0 so that therewill be sufiicient friction to cause the shaft B to rotate to cause the endless record carrier to move as hereinafter described.

The disc 0, see Fig. 11, is provided, around its periphery, with twelve ratchet notches, six of which, a are not out as deep as the: remaining six notches 0 The purpose and operation of these notches a and 0 will be fully explained hereafter.

At the intermediate part of the frame A, see Figs. 6 and '7, are provided journal bearings A and A, in which are placed rockshafts D and D of swinging brackets D and D see Figs. 1, 4, 14, 19 and 30. These rock-shafts D and D are secured against longitudinal movement by means of rings d placed on their inner 'ends, and secured thereon by means of set-screws d. The

rings d are provided with ar ms d and d? see Fig. 32.

Attached to the arms d and d are springs d and (Z which have their opposite'ends secured in cars a on the frame A so that the action of said springs tends to swing the brackets D and D upwardly.- At each side of the axes of rock-shafts D and D on the opposite sides of the frame A are stops, a against which the brackets D and D contact to limit the downward and upward movement of said bracket.

and E the chuck E being adapted to lift I the records from the carrier bars b and the chuck E being adapted to replace the records back in the carrier bars, working alternately.

Inrthe hinge part D is placed a spring D in the manner usual in such hinges, which operates to maintain the hinge normally open as shown in Figs. 1 and 19, and when the hinge is operated as hereinafter described, assists in lifting the chuck bodies back to their normal position.

These lifting chucks E? and E are duplicates, with the exception that their construction is reversed, so that they face each other. Their construction is as follows, reference being had to Figs. 19 and 20, viz:

llt

lli

They are preferably partly circular, and

bowl shaped, with a segmental indentation ribs a between which are pivoted record gripping hooks a and 6 which are 019- eratcd by means of connecting bars 6 Pivoted in the center of the chuck body is a shaft E which is provided with three radial arms 6} from each of which link bars a extend to and are pivoted to the ends of the connecting bars 6 A spring E" is provided to operate the gripping hooks e and 6 to engage a record disc. The shaft E is provided with an arm e from which a link-bar 6 extends to one arm of a bell-.

crank lever E pivoted at the periphery of the chuck body, the other 'arm of which ex tends over the upper end of the hollow hinge pin (Z \Vhen the bell-crank: lever E is operated, as hereafter described, to rock the shaft E against the action of the spring E the gripping hooks e and 6 will swing outwardly from the 'centerof the chuck body, the hooks e completely receding back of the face of the chuck, and the hooks 6 swinging out into gripping position. If a large record is presented to the chuck, the hooks and the mechanism released to the action of the spring E the hooks 6 will grip the edges of the record. 1

If a small record is presented, the a will swing inward as shown in Fig. 20, and the hooks 6 will grip the edge of the record.

The face of the chuck is covered by a plate which is secured in place by means of screws 6 see Fig. 20 and which plate is provided with slots through which the record gripping hooks e and e operate.

Pivoted inlhe lower side of the swinging bracket D is a bell-crank lever F, one arm of which extends under the lower end of,

, the hollow hinge-pin (Z and in said hingepin' is a rod (Z which extends from said bellcrauk lever upwardly to the end of the bellcrank lever E so that when the bell-crank lever F is operated the movement is comniunicated to the chuck mechanism hereinhefore described. I

Upon stud-shafts F and F secured in the machine frameA, are bell-crank levers f, f, and from one arm of each bell-crank lever f a link f extends to the upwardly extending bell-crank lever F, and from one of each bell-crank levers f links f extend to ears 7" on the lower hinge-lugs E of the lifting chucks E and E3. The ends of the arms of the bell-crank levers and f to which the links f and f are pivoted, are on the line of the axis of the rock shafts D and D" so that when'the chucks E and E are swung upwardly as hereinafter de hooks scribed, the links f and f swing si1'nultaneously without interference to their operation.

Mounted in a vertical journal bearing G in the frame A, isa spindle Gr for a'turntable G This spindle G is provided with a hub G at its upper end, around which is formed-skew gear teeth. Above the hub G is a friction disc g, upon which the turn table G rests. The under side of the turn xtable is preferably provided; with a recess to receive the friction disc, 7, and by which it is centered on the spindle. The lower' end of the spindle G stands upon a ball g, see Fig. 30, which rests upon a screwplug 9 In Figs. and 36 I-show a shaft mechanism for operating the several mechanisms of this machine which consists of theshaft H which is mounted in a suitable bearing ment in the bearing. Upon the shaft H, I

place a sleeve H which is provided with, a thrust flange h which enters a recess on the inner end of the bearing a and is retained k therein by a ring, a which issecured on the inner end of the bearing a preferably by boltswhich pass through the body of the bearing a and ring a and are threaded into the ring a, so that the sleeve H is secured against longitudinal movement, but is free to revolve. I

Adjacent to the inner end of the sleeve H there is a worm thread If. and on the inner end of the sleeve H are radial ratchets, or clutch teeth k Upon the shaft H, I then place a slidable sleeve clutch H through-the walls of which are'longitudinal slots it, through which a transverse key 7L passes, said key also passing through the shaft H, in which it is secured by a setscrew H The slots h, in the sleeve H being long enough to permit the clutch. sleeve H to slide as hereinafter described. Each end of the sleeve H is provided with. radial ratchet clutch teeth 71. which are gilapted to engage the teeth h? and the sleeve Upon the-inner end of the shaft H, I place a sleeve-shaft H one end of which is provided With radial ratchet teeth H adapted to be: engaged by the teeth k on the end of the clutch sleeve H and adjacent to said teeth H is a worm thread H and at the opposite end I provide a worm thread H ion bearing G, the worm thread H engaging.

the skew gear teeth G on the hub of the lac spindle G as shown in Fig. 31. The spindle ..broken lines in Fig. 1. Upon the outer end of the shaft H, I place a pulley H upon which a belt, J, shown in broken lines, is placed, which is operated by a pulley J on a motor J When the clutch-sleeve. H is in the position shown in Fig. 35, and the motor is started, the sleeve shaft will revolve and cause the turn-table to revolve.

Under the turn-table there is the usual horn or resonator, J and upon the upper end of this .resonator is the swivel J for the tone arm J This swivel J is constructed as follows, reference being had to Fig. 33, viz:

Upon the upper end of the resonator J is placed a ring j which is provided with spokes j at the intersection, or hub, of which is a vertical tube 7' and upon this ring 7', is placed a ring of felt j Upon the ring j is placed another ring 9' which has an. internal spider j which supports a vertical tube J 6 which receives the tube 7' and swings thereon. The ring j* is provided with clamp-ears j through which a.

clamp-screw 7' passes to secure the tone-arm J 5 firmly therein.

The ring 1' is provided with an arm J" by which the ring 9" and tone-arm J are operated as hereafter described.

, The tone armJ is provided with a vertically hinged extension J 8 which is adapted to swing upon the pivot screws j, and upon this extension the sound box is secured.

Within the tone arm is a needle lifting lever K which is pivoted to the hinged extension J back of the pivot screw j, and has a short end is which engages the upper wall of the hinged extension. The long end of this lever extends backward to a point directly above the upper ends of the tubes i and J and from this lever a cord extends downward'ly through said tubes, and through the resonator J shown by broken lines in Fig. 5, the lower wall (not shown) bein provided withan opening for said cord or the purpose-hereinafter described.

The mechanism I have designed for actuating the several mechanisms hereinbefore described, consists of a cam-shaft L,

' which is provided with a worm gear wheel shaft L with relation to each other that the mechanism actuated thereby, will move in timed sequence with relation to each other as will be hereinafter described. The camshaft Lv is mounted inv suitable bearings L on the machine frame A, see Fig. 3. L see Figs. 1, 4, 5, 14 indicates a transverse shaft secured in the bearing blocks L parallel with the cam-shaft L, and does not rotate. Upon this non-rotatable shaft L are canilevers 1 to 11 inclusive, see Figs. 21 and 22, which illustrate the association of said cams and levers. i

M indicates a feed shaft .see Figs. 1, 3, and 8 which is mounted in the bearing blocks L in the frame A, and is provided with a worm gear M which meshes with the worm H on the shaft H and said'worm gear wheel being on the side of the shaft H opposite to the worm gear wheel L, is rotated by said shaft in a direction opposite to the direction of rotation of the worm gear L. The feed shaft M is provided with a sleeve M which is free to rotate on said shaft. This sleeve M has secured thereon a cam sleeve M which has cam edges m, 922., against which a spring pressed roller N operates for the purpose of insuring the coming to rest of the sleeve M with the short arm m in the position thereof shown in Fig. 8. The sleeve M is provided with annular clutch teeth, m Upon the feed shaft M are splines m see Figs. 8 and 10*, upon which a sleeve M is slidably placed, so thatwhen the shaft M revolves, the sleeve M must revolve with it. The sleeve M is provided with annular clutch teeth, m which are adapted to engage the teeth M on the sleeve M as hereafter described. Upon the shaft M between the adjacent ends of the sleeves M and M is a spring M The sleeve M is provided with screw-threads for the purpose hereinafter set forth. livoted' 1n the frame A is a U-sha'ped bracket 0, by means of a pin 0, and between the arms of said bracket a sleeve O v see Figs. 9 and 10 is mounted on a pin 0. Upon the sleeve 0 a gear segment 0 is secured which meshes with the screw-threads m on the sleeve M The hub 0'. see Fig. 10, of the segment 0 is provided with stud posts 0 and 0 Secured to the frame A is a stationarybracket N see Fig. 8 which is adapted to engage the stud post 0 on the hub 0 '0 by means of the clamp 11, is anarm N in the free end of which is pivoted a link N the adjustment of the angular relationship of said arm N and link N being regulated by means of a thumb screw n, for the purpose hereafter described. The link N is provided with a segmental plate N having thereon a graduation to indicate the degree of angularity between the arm and link. 1

In the end r the link N3 rod 1v is piv- I 01?, see Figs. and 9,'is pivoted, which eX- tends to and is pivoted to the swinging bracket 0, so that when cam 1 operates the cam lever 1 the swinging bracket 0 is caused to swing to the position thereof shown by broken lines in F 8. The swinging bracket is moved in the opposite direction by a spring 0 see Figs. 3 and.5, which is attached to the frame A. Pivoted to the cam lever 2 is a rod P, see Fig. 5, which is connected to a lever P by means of an adjusting swivel p. The lever I is fulcrumed on bracket 79 which is secured on the frame A, and extends under the resonator J where the cord 70 see Fig. 33 is secured thereto, so that when the cam lever 2 is operated by the cam 2 the sound box K will be raised sufiiciently to lift the needle out of contact with the record disc on the turn table G as shown by broken lines in Fig. 33.

the rock shaft D.

To the cam lever 3 is pivoted a rod P by means of an adjustment swivel, which rod extends and is pivoted to the bell-crank lever f see Figs. 19 and 19, by means of which, when the cam lever 3 is operated by thecam 3, the record gripping mechanism in the lifting chuck IE will be'opcrated, as

hereinbefore described.

To the cam lever 4 a rod P extends and is pivoted to the bell-crank lever f see Figs. 19 and 19, so that when the cam lever 4 is operated by the cam 4, the power is exerted through the link f, see Fig. 19, to cause the lifting chuck E to swing from avertical to a horizontal position on the swinging bracket D see Fig. 1 so that said bracket.

will be stopped by the lug a? at the left of To the lower end of the cam lever 5. a rod P is pivoted and extends to and ispivoted to an ear 19 see Fig. 19. on the upper side of the swinging bracket D see Figs. 1, and 19? so that when the cam lever 5 is-operated by the cam 5, the swinging bracket D will raise the lifting chuck F to a vertical position.

Cam lever 6* is secured upon a shaft Q, mounted in the two intermediate bearing blocks L on the frame A, and on the rod Q, is a yoke Q, see Figs. 35, 36,'and 37, for shifting the slidable clutch H on the driveshaft H, out-of engagement with the shaft H and into engagement with the sleeve H, for the purpose hereinafter described, so that when the cam lever 6 is operated by the engagement therewith of the short arm engagement with the shaft H m on the sleeve M the cam lever 6 will cause the chuck sleeve H 'to be disengaged engages said cam lever 6 and operates the same to again shift the clutch sleeve H into.

()n the shaft Q is an arm Q see Fig. 27, which is provided with inclined surfaces on the upper end thereof which meet on the center line thereof, and above the upper end of said arm is a spring pressed lever Q provided with a roller 9 in the end thereof which operates to cause the arm Q to throw the clutch sleeve either way, longitudinally.

The construction of the cam 6,-is as follows, see Figs. 23, 24, 25, 26, 28, and 29. There are two parts; and The part 9' is non-rotatably secured upon the cam shaft L by means of a transverse pin through said shaft. At each side of the part L which connects said discs g to the cam lobe 9 which operates in a recess g, see Fig. 24, in which is placed a spring 9 to yieldingly maintain the lobe in the position shown in said figure. Now as the cam shaft L rotates the cam. 6 in the direction shown in Fig. 22 it engages the cam lever 6 and operates said lever until the lobe g passes the lever 6 when the spring throws the lobe clear of the end of the lever 6 so that it can be swung back to its normal position by the armQF; thisis necessary because at the instant the arm 9 operates to throw the clutch sleeve H the cam shaft L and cams cease to revolve. k

Pivoted on the lever 7 is a rod 79 which extends and is pivoted to the swinging arm 12 see Fig. 5 mounted on the shaft B upon whichis pivoted a spring pressed ratchet dog 72 which is adapted to engage the ratchet teeth on the Y friction disc C, see Fig. 3. i

The cam 7 first engages the roller in the short arm of cam lever 7, see Fig. 22 which causes the'swinging arm 29 to swing upwardly so that the dog 79* will engage the second tooth on the disc C, and continuing its revolution the cam. Tengages the roller 'in the long arm of said cam lever and forces it downward, which through the rod 30 and dog 39 causes the disc C to revolve which by means of the friction caused by the discs C and C see Fig. 13 causes the shaft B to move the record carrier forward until the travel thereof is stopped by a record disc 6
