To all whom it may concern:

Be it known that T, HOWARD L. PAGE, a citizen of the United States, residing at Chicago,'in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Phonograph-Record-Transfer Machines, of which the following is a specification.

, The object of this invention is to provide a machine by which a phonographic record on a continuous tape or film, for instance a such a record as is shown described and claimed in my companion U. S. patent application Serial No. 560,221 filed May 11, 1922, may be transferred by the aid of a needle cutting into a wax or other surface of another record to such record. The record to which the transfer is made may be of any conventional form, however the particular embodiment of the invention here shown illustrates such a machine designed for the transfer to a circular wax disc and it will, therefore, be so described.

In the present method of producing wax or similar surfaced phonograph records it is necessaryfor the person whose voice is to be reproduced to talk directly to amachine carrying the wax coated record member which means that the record member has to move fast enough to receive the voice variations which means that the record has to have wax thereon of a given tenacity to stand the speed. In actual practice under these conditions a' great many faulty results are produced which cannot be removed. By making the initial phonographic recordby the photographic ,method of said prior application and then using the machine of the present invention, "an accurate photographic record can be transferred to the wax of the record,in this particular case a circular disc,

at any'speed desired say one foot perhour if necessary as. distin ished from 40 feet per' minute by the 01 method. thereby insuring substantially accurate recording on the wax disc of all voice variations of the I original photographic record.

The object of the machine isto produce a machine giving this very desirable result.

The invention consists in a machine'capable of attaining the foregoing objects which can be. comparatively easily and cheaply built which is very'accurate and efiicient in its use and is not readily liable to getout ofordera More particularly the invention consists in other special features and details of invention which will be hereafter more fully set forth in the specifications and claims.

Referring to the drawings in which like numerals indicate the same parts throughout the several views-.

Figure 1 is a side elevation of the mechanism illustrating theinvention in its preferred form. I I

Figure 2 is a plan view of the essential center part of the machine of Fig. 1.

Figure 3 is a detail plan view, partly in section, on the line 3-3 of Fig. '1.

Figure4 is a vertical sectional side View on the line 4-4 of Fig. 1.

The machine'is mounted on a main frame preferably secured to thefioor or other base support by any suitable means such as the lag screws 12. Extending vertically in the machine is an elongated slot whose opposite guides 18 for cross head 20 vertically reciprocablethereon. Rigidly attached to this cross head as by a pin 22 is a vertical screw parallel vertical side walls 16 carry threaded member 24 interfitting into the screw threads 26 formed in a tubular perforation in a rotatable shaft 28*journaled in the cross member frame part 30 lying at the upper end of slot 14. The upper end of this shaft 28 carries a bevelgear 32 meshing with a bevel pinion 34 on a shaft 36 suitably journaled in vertical uprights 38 rising from a bracket arm 40, secured to the side of block 30 by any suitable means as the screws 42. Rigidly mounted on the shaft 36 is a pulley 44 lying in the same vertical lane as another pulley 46 carried by a sha t 48 journaled in cross head 20. Over thesetwo pulleys 44 and 46 and a plurality of other guiding pulleys 50 is a belt 52 carrying a vertically reciprocating pulley 54 from which is suspended a counterweight 56 adapted to ,maintain the belt 52 tight regardless of the distance apart which the pulleys 44 mechanism between them heretofore described, is adjusted by the rotation of shaft 36 and pinion 34.

Between the supports 38, shaft 36 also carries ailarger and wider pulley 58 over which photographic phonograph record film or tape 60 passes from one storage reel as 62 to another: similar reel as 64, the tape in the meantime traveling over intermediate supporting pulleys 66 and 68.

and 46 may be, as the screw too plication the film or tape 60 carries a raised record member'ZO having a waving record line 72 formed thereon capable when engaged by'reproducer bar 74 placed angularly'thereto to nism attached to and manipulated by the bar, an accurate reproduction of the sound waves originally impressed upon the record 70. This bar is pivoted at its end 76 which is mostremote from the record 70 to a bracket 75 suitably mounted on the frame of the machine. Pivotally attached to the bar 74 intermediate of its ends as at 78 is a vertically depending rod 80 guided in a verti cal plane by sliding thru a lug 82 also suitably attached to the machine. On the lower end of the rod 80 is alaterally extending needle, knife or other cutter 84 so positioned as to operatively engage a conventional circular disc 86 carrying on its face adjacent to the needle a wax surfaced pulley .88 adapted to have the photographic record cut therein by the tool 84. This disc 86 is suitmeans as for instance the ablysecured to the shaft 48 by any suitable clamping disc 89 and the hand nut 90 adapted to permit ready removal of the disc 86 whenthe recording operation is completedon the wax 88 thereon'and the substitution therefor of another disc ready for the making of a new record.

The pitch of; the screw device 24'Q6 is such that as the disc 86 is rotated the resulting record line cut in the wax 88 by needle 84 will take the spiral form well understood in the disc phonographic art.

In theo eration of thedevice the parts are assemb ed as shown in the drawings.

not shown applied to a pulley 920m the end of shaft 36 to thereby-causethe machine to operate to cause the photographic record to pass under the bar 74 thereby causing the sound record represented by the line 72 to be communicated to the bar and rod and the needle 84 which cuts a wavy line in 'the wax 88 conforming to the motion re ceived from the record line 72. As the shaft 36 rotates it causes shaft 28 to rotate andpulls screw 24 and cross head 20 and attached bar upward just a sufficient amount so that the record line formed by needle 84 is spiral as described,.the weight 56 keeping belt 52 tight so that there is no lost motion in the device. The operation described is continued until the wax 88 on the disc 86 is made into a complete record whereupon the-disc may be removed and a new one substituted.

By lifting the right hand end of bar 74 against the tension of spring 94: which normally holds it on the record line 72. the operatorcan readily remove the original record tape 60 from the machine and substitute another one.

give off thru proper mecha support and two movements Having thus described my invention what I claim as new and desire to secure by Letters Patent is;

1. In a phonographic record reproducing machine, a support for an undulated record, a support for a record blank on which the undulations of the record are to be reproduced, means for simultaneously imparting a single movement to one support and two movements to the other support, and means adapted to be operated by movement of a supported record to reproduce the undulations thereof on a supported record blank during movement of the latter.

2. In a phonographic record reproducing machine. a record support, a support for a record blank, means for simultaneously imparting a single movement to said record to the support for a record blank, operated by a record carried by and moving in harmony with said record support to reproduce said record on a record blank during movements of the latter in harmony with its support.

3. In a phonographic record reproducing machine, means for supporting an undulated strip record and imparting a single movement thereto, a two-movement support for a record blank on which the undulations of the strip record are to be reproduced, means between the supports for effecting one of the movements of the two-movement support, and means operated by movement of a supported undulated strip record to reproduce the undulations thereof on the blank during k movements of the latter. The power is appl ed to themachine at any convenient point. as for instance thru a belt 4. In a phonographic record reproducing machine, a support for an undulated record. a support for a record blank on -which the undulations of said record are to be reproand means adapted to be duced, means for simultaneously imparting a single movement to one support and two movements to the other support, and means adapted to be operated by movement of an undulated record carried bysaid record support to reproduce the undulations thereof on the record blank during movements of the latter, said means comprising a bar having one end pivoted and engaged at a point remote from its pivot with the undulated record, an arm connected with saidbar between its pivot and the point of engagement there of with the undulated record, and a stylus carried by said arm and engaging the record blank on which the undulations are to be reproduced.

In witness whereof, I scribed my name in the nesses.

have hereunto subpresence of two wit- HOWARD L. PAGE.
