To @ZZ whom it may concer-n:v

Be it known that 1, BENJAMIN DUBINSKI, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Phonograph-Machine, of which the following is a specification.

This invention relates to sound-reproducing machines, and especially to a machine of that general class in which a plurality of records are presented successively to a single sound-box.

The principal object of the invention is toimprove and'simplify the sound-box-traversing mechanism and insure uniformity of movement of the same at each operation, a furthei object inthis` connection being to provide for the movement of the sound'- box away from the record atprecisely the same A further object of the invention is to provide for the returning of the carriage to its initial or starting position after each reproducing operation and to prevent premature return movement by so constructing the mechanism that the sound-box will be moved away from the record .before the latter is released and allowed to' start o n its return movement.

A still further obj ect of the invention is to provide for the accurate adjustment of the position ofthe sound-box with relation to the prevent excessiveJ inward movement of the sound-box and to provide means ,whereby the sound-box is yieldably held andis free tomove outward to a greater or less extent during the reproducing operation.

improve .the construction ofthe record-carriers and to rovide means -for locking the records from rongitudinal movement fon the carrying cylinders or mandrels.

With ,theseand other objects in view, as will more fully hereinafter ap ear, the invenin certain vnovel eatures of construc-tion and arrangement of partshereinafter fully described, illustrated inthe ac'- companying drawings, and particularly pointed out in thel appended claims, it being understood that 'various changes in the form, proportionasize, and I `nor details of the be made without vdeparting I shaft 12, that carries at A still further object of the invention is to j end view of the same, partly in section, on-

the line 2 2 of Fig. l. Fig. 3 is a detail perspective 'view of a portion of the sound-boxcarrying shaft and the lever for rocking the same. Fig. 4 vis a detail view, partly in section, of the mechanism for traversing the sound-box carriage during the reproducing o eration. Figs. 5 and 6 are similar views of t e same -mechanism with the parts'in different ositions. Fig. 7 is a sectional elevation of t e same on the line 7 7 of Fig. 6. Fig. 8 is a detail sectional view of a ortion of the sound-box carriage and its roc -shaft 9 is a transverse sectional view of the same on the line 9 9 of Fig. 8. Fig. 10 is a sectional view of one of the'record-carrying mandrels, showing a record in position thereon.

Similar numerals of'reference are employed Fig.

The present application relates to certain improvements in )sound reproducing machines ofthat general type shown in Letters Patent No. 773,486, granted to me October 1 I' 25, 1904, and to which reference may be had for specific details of construction not yshown or described in the present application.

The ratus are supported on cluding end standards 10 and 11,'thatare provided with bearings which are secured a said shafts extending the main shaft 12 and being connected at their opposite ends to a ring 15.... .The shafts 14 are provided withreduced threaded terminals adapted for the reception of thumbnuts y16, by which they may be Jrmly clamped slots for the passage o said shafts in order to principal working parts of the appa-'f a suitable frame, in-

for the reception of a one end a disk 13, to plurality of shafts 14, in parallel relation with in place, and-the rin 15 is provided with IOO permit the convenient introduction and removal of the latter when it is desired to change the records.

Thef several shafts are non-revoluble and barry sleeves 17, that may be locked in any* adjusted position by 'set-screws18,wthes'ei sleeves forming conical bearings which fit in f and operates on 'upper and lower suitable o enings formed end disks -19 of the recor -carrying mandrel's 20,-' thelatter being tapered inform and adapted to'receive records of the usual construction. The" larger end of the mandrel, or that end adjacent to the disk 13, is provided with a grooved friction-face 22, which is engaged by-a fric tion driving-disk 23 in the manner hereinafter described for the purpose of imparting rotative movement to the mandrel. The

.record is heldl from longitudinal movement Mounted 1n suitable bearings. in the lower portion of the frame is a horizontally-di's-` posed shaft 28, on which is ivoted thelower end of a frame 29, and said ame is provided ,at its upper end with bearings for a drlveshaft 30, which extends within the annular series of record-carrying mandrels and car-y This shaft ries the friction driving-roller 23. n

is provided with a grooved pulley which movement may loe-'imparted suitable driving-belt. the shaft 30 is a Worm 32, that intermeslres with a worm-wheel 33, carried by an ap-v proximately vertical shaft v34, that'is supported by brackets 35, projectingfrom the ortions` of the rocking frame'29, and at thellower end'of thev shaft 34 is a worm 36, that interineshes with a Wormwheel 37 on a shaft 23,;the gearing being so .proportioned that shaft'30 in rotating a suflicient number of times to'eifect thereproduction of an entire record will effectja singlel rotation of the shaft 23.y

Secured tothe shaft y is adapted to engage with'the' lower yarm'41 of a bell-crank leverthat is pivoted on@ stud main frame. r.,lhe upper arin 43 of the bell-crank lever extends v 42, projectingv from the 'through the rocking frame 29 and engages a cross-bar on said frame, 'sothat when the shaft 23 turns the cam`40 to proper :position the arm 41 of the `bell-'crank lever the rocking frame 29 will be drawn to the rear and the friction kdriving-pulley 23 will be forced out of engagement with the friction-pulley of` the record-mandrel, and

when the parts are in normal position-that is to say,`vvith the sound-box out'of contact with the records and at its initial starting'- point--the projectingv active surface "of `the cam 40 will hold the arm 41 of 'the bell-crank` lever in elevated position, and the rocking frame will `be in its rearmost positionwith the driving pulley 23Y inoperative ;i.A Thestarting of the machine due to theinsertion of a coin or the operation of a push-button` .or the like imparts rotative movement to the br i 'a At the outer en of asis @bastia-that t vManet-screw' 57.

shaft 30, and j this movement transmitted through the worm-gearing to' the shaft 28 v causes cam'- 40 to move from the bell-crank lever. 41 and the llatter in descendin allows the frame' '29 to swing forward until t e driving-pulley 23 engages with the friction-pulley of the adjacent record-carrying mandre At the completion of each'reeording operation the projecting surface of .thecam agrain engages the arm 41 and thev rocking ame is moved back to inoperative position. The details of this mechanism, w `ch form no part of the present invention, are fully described and illustrated in the Letters'y Patent hereinbefore referred to.

"At the upper front portion 'of -thernachine .is a rockshaft 45, that fis "held in suitable bearings in the main frame` and serves as a vsup ort for .the sound-box carriage 46. This sha ti is'provided with a groove 47 that extends for practically the entire length of thel shaft and is adapted for the reception of apair of antifriction-rollers 48, carried by screwsor studs-49, that extend through 'threaded openings formed in an elongated'sleeve 50, that constitutes a base for the sound-box carriage. yTo .this shaft issecured one end. of

a helical spring 51, which is Wound around the shaft, and has its o posite endsecured to a pin or scew 52 on t el main frame, the spring vtending to turn thevroclr-shaft and force the reproducing-stylus of the soundvbox against the .record and said spring allowing the sound-box to yield to a greater or less extent during the reproducing of the record.

Depending from the sleeve 50 is an arm 5 3 that carries at its lower end an antifriction-roller 54, which when the sound box is in reproducing position travels against a stationary rod 55,' that extends between the standards vl0 and 11 to prevent excessive inward movement of the carriage in case 'j cf accidental yIco breakage or imperfect a djustment of other portions ofthe mechanism.

Secured to one end of thexshaft 45 is a col-iA llar 56, whichmay be revolubly adjusted on the shaft and locked invadjusted position by a'pendent pin 58, the lower end of which enscrew` 60, that extends through a `threaded opening in a bracket 61', carried by the standard 11, said screw being' proper position andthenblocked by a nut G2 and serving as a. means for limiting rotative movement ofthe rock-shaft in the direction necessary toefl'ect engagement between the reproducing-stylus and the record.

r Pivotally connected to the upper portion of theroclring frame 29 is a bar 64, the outer end of which is guided .in a suitable opening formed in the bracket 61, andin the outer face ofthe bar is a notch or recess 65, through which. the pin 53 passes, rihis bar serves as This collar is provided withv first adjusted to v vI O a means for moving the sound-box toward and from the record, and on reference to Fig. 2 it will be noted that the connect on is such that when the friction-disk 23 is in operative position the sound-box is also in operative position. If the rocking frame 29 is thrown rearward to move the friction-disk 23 to inoperative osition, the movement will be transmitte through the bar 64 to pin 58, and the shaft 45 will be rocked to such position as to throw the sound box outward away from the record a position to permit the return of the sound-box to its initial position,this position being determined by a collar 67, that is carried by the rock-shaft 45, and which may be firmly locked in any desired position of adjustment byaset-screw 68.

Mounted loosely on the shaft 28 is a grooved windin drum 70, to`whieh is secured one end o a flexible member 71 in the form of a cord or chain. This flexible-member is guided by sheaves 72 and 7 3 and at its opposite end is secured to an eye formed in a lug 74, projecting from the endent arm`53 of the sound-box carriage. en this drum is turned in one direction, the exible member is wound thereon and the carriage is drawn lengthwise of the record during the reproducing operation. To restore the carriage to initial position, a Weight 75 is connected by a .suitably-guided flexible member 76 to an eye formed in a lug 77 at the opposite side of thependent arm 53, the Weight being elevated as the carriage is drawn to the right during the reproducing operation and descending to draw the carriage to the left at the completion of such operation.

The winding-drum is rovided with a recess 77, which is adaptedp to receive a key or lug 78, projecting from the shaft 2 8, and said drum is constantly pressed in the direction of. the key by means of a helical com ressionspring 80, surrounding the shaft ano bearing at one end against the drum and at the opposite e'nd against an adjustable collar 81, carj ried by the shaft. On one of the flanges of 'the drum is a cam 82, which as the drum revolves comes into engagement with a stationary cam 83, carried 'by the frame, the arrangement being such that the drum will rotate a triiie less than a complete revolution at each operation, and this partial rotation will be suflicient to move the sound-box for the full length of the record.

When the parts are. in normal fpositionthat is to say, are not operating-the straight faces ofthe two cams or those faces parallel.

with the axis of the shaft 28, are in contact with each other, the stationary cam 83 acting as a stop forthe cam 82, and at this time the key or lug 78, is not in the recess 7 7 As soon as shaft 28 commences to rotate the 4key or l-ug 78 will rotate until it is. o posite the recess 77,l whereupon .spring 8O force the drum in the direction ofthe key and the latter will b`e entered in the recess, andv thereafter during the remaining portion of the rotative movement of the shaftH the drum will be ted to the sound-boxcarriage. As the soundbox nears the end' of the record the inclined face of the cam 82 starts to ride against the inclined-face of the cam 83,and at the completion .of the reproduction the drum hasbeen forced outward to such an extent that'the key or lug 78.isrwholly outof the recess, whereupon the Weight 75 acts to return the sound-box carriage to-its initial osition, and previous to 'this operation the rame 2,9 has een rocked to the rear and its movement has been transmitted to the rock-shaft 45, raising the reproducing-stylus from engagement With the'record,`the cams 82 and 83 bemust -act in advance of the cams 82 83 and o sitively move, the sound.- box outward om the record before A the drum is released from the shaft. The descending movement of the weight 75 pulls the carriage to the left and at the same time rotates thewindingdrum 7() in a direction opposite to that in which itv turned duringv the reproducing op,- eration. The Amovement stops when vthe straight face ofthe cam 83 engages .against the corresponding face4 of' the cam 82.

With a device constructed accordance with this invention it is absolutely-uniform resu s, the .sound-box being traversed to precisely vthe same distance at each operation and returning to precisely the same point after neach operation, and owing to the positions of the actuatingcams it is impossible for the carriage to start on its retu'n movement until after the stylus has been moved from engagement with the record.

Having thus described the invention, what is claimed is combination with a sound-box carriage, of a support on which saidr carriage is slidably mounted, a Winding-drum, a flexible connection between the Winding-drum and the carriage, means for operating said drum to feed the carriage in one direction, means operable on lessthan a complete rotation of the drum for stopping the, winding'- ,operatiom and means for restoring the carriage to initial position.
