PHONOGRAPH.

Specification of vLetters Patent.

`Patented Nov. 9, 1909.

Application led December 22, -1908. Serial No. 468,815.

' which the following is a specification.

- are pivoted to admit the is for the purpose of enabling the assembling vof .these cylinders and also for My invention relates to improvements in means for increasing the available recording surface in phonograpl1s, and it consists in the constructions, combinations and arrangements hereinafter described and claimed.

An object of my invention is to provide a phonograph in which a record surface of a flexible nature and having a relatively great length -Inay be insertedor removed, and in which the bearing members for the cylinder ment of the record. y

A further object of my invention is to provide a record applicable to a cylinder type, in which the virtual diameter of the record is greatly increased, while the actual diameter is not.

Other objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, in which- Figure l shows an end view of a phonograph containing one embodiment of my invention. Fig. 2 shows a side view thereof, and Fig. 3 is a plan view.

'In carrying out lmy invention I provide a lframe A in which'is supported the upper feed rollenB having a flange bX on one end and a lower roller C', having a similar flange c". These rollers are journaled in the bearings 'b and bx and aand c", respectively, carried by the uprights of t-he frame The bearingsb and c are elongated as shown in 'F ig. 2 in order to support their respective shafts when the cone bearings BX and The cone bearings bx and 0X are hinged to one of the uprights of the frame A atby and cy, respectively,and may be locked atV th opposite ends bz and cz, as clearly shown in Fig. 1. This construction slippin on the flexible record D.. u g

The flexible record D is preferably an endi, less band composed of any suitable material removal or replace- Cx are removed from the ends of the` shaft.

which will permit a bending of the band or belt such as the films` of moviiw )icture mavcorrespondi]1g to the height of the frame A.

A longer belt would be used with a correspondingly higher frame. thus giving a greater record surface. 'lhe belt may be ot' any width, butin practice I find it preferable to use a belt with a virtual diameter of thirty-six inches and a width of six inches on a feed cylinder of approximately live inches in diameter. After the belt is slipped on, the slack may be adjusted lo the proper degree by a movement of the upper part of the frame relatively to thelower or by a movement of the bearings of one of the 1ollers. The roller C may be of any convenient diameter and 'serves merely as an idler.

The diaphragm E may be any standard diaphragm andis preferably supported by means of the arms e and e. The arm e is provided with a guide sleeve c2 arranged to travel back and forth on the guide rod F. The arm c on the opposite side is provided with a feed member G arranged to coperate -with a feed screw H. The feed roller B may Y be driven by ineans of a belt (not shown) ruiming over a drive pulley K, by any "suitable power. Thefdiaphragm may be provided with the usual horn or sound intensilier L.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. When the machine is assembled in the manner already indicated and the needle is placed at one edge of the continuous band, the rotation of the feed cylinder 5 will cause the belt 9 to move under the needle and the action of the feed screw will cause the needle to be shifted Alongitudinally of the belt. It will thus be seen that with a feed cylinder, say of five inches diameter, the effect of ane-ndless belt traveling over said cylinder will be' that of a cylinder of a virtual diameter equaling that of the belt, thereby giving a much larger record surface without much increase in the feed cylinder. Of course the feed screw Il may be made to advance the needle transversely of the belt, z'. e. longitudinally of the feed cylinder at any predetermined rate.

Byusing a record belt of a virtual diameter llO of thirty-six inches with ninety-six threads upon the feed screw for every inch in length of the feedcylinder (or width of the belt), we will oly -ain a record having a length approximately sixteen times the length of the ordinary cylinder record. Used at the saine record speed of the ordinary-cylinder machine, it will require nearly fifty-eight minutes time to reproduce this record.

In the effort to make phonographs of com! Vparatively small size but with large record surface for use in connection with motion pictures, 1t will beat once apparent that this device furnishes a means for overcoming the obstacles in connection with the recording,

or rather reproductiolnof long speeches to correspond with, or accompany, the actions v of the characters in the motion pictures. So

alsoan opera of considerable length may be recorded by means of a machine equipped with my invention.

While I have shown this device as consisting of a ame of a special form, it will be understood that any. frame suitable for the esaeo arranged in the other end of said frame,

hinged bearings for said feed roller and said idler, a flexible recording surface carried by said feedvroller andsaid idler, said recording surface consisting of an endless belt arranged to run on both of said rollers, and

va st lus arranged to engage said recording sur ace.

2. In a phonograph, a frame :provided with upper and lower stationary bearings, a feed roller mounted in said upper bearings,

an idler mounted in said lower bearings,

upper and lower hinged bearings carried by said frame and arranged to swing into alinelment with the respective upper and lower stationary bearings and a flexible recording` ysurface carrled by sald rollers.

In a phonograph, a frame provided with upper and lower vstationary bearin s, a shaftl having a guide flange on the end o the roller adjacent the stationary bearing, a lower shaft journaled in said lower stationary bearing, an idlerearried by said lower Y shaft and provided with a flange on the end adjacent the stationary bearing, and upper and lower hinged bearings carried by said frame and arranged to swing into alinement with their respective stationary bearings and adapted to engage the ends of the' upper and lower shafts respectively.
