7 '0 all whomtz't may concern:

Be it known that I, AnoLPH 'SGHWER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a certain new and useful Improvement in Phonographs, of which the following is a specification.-

This invention relates to improvements in phonographs. v i

One of the features of the invention has reference to a disk record mechanism and a cylinder record mechanism, eachof which is complete in itself and independent of the other, a driving mechanism andmeans for connecting the driving mechanism with either the disk record mechanism or the cyl-. inder record mechanism.

Another feature has reference to the mounting of the disk record mechanism, the cylinder record mechanism and the driving mechanism ona movable base or support .so that said mechanisms ma be quickly and conveniently exposed for a justment 'orreair. P Another featurehasreference to the mannor of starting and stopping the driving mechanism, re ulating the speed and shift-- ing from the isk record mechanism to the cylinder record mechanism or vice versa.-

The principal objects of the invention are to provide for almost instantaneously changing from one record mechanism to another, to perfectly control and regulate the speed at will, to start and stop the mechanism when desired, and to arrange the various mechanisms so that they are quickly accessible for adjustment or repair.

The invention also relates to certain details of construction which will be hereinafter described and claimed, reference being had to the accompanying drawingsdn which a preferred adaptation of the machine is shown.

Figure 1, is a top plan view of the improved phonograph. Fig. 2, is a vertlcal transverse sectlon through the upperportion of the box of the machine with a front elevation of the various mechanisms attached the same. Fig. 3, is a fragmentary perspective View to illustrate the' toggle clutch operating mechanism. and one member of one of the clutches. Fig. l, is a fragmentary horizontal section'through the box with a bottom view of the driviljg mecha-v nism. Fig. 5, is a fragmentary vertical sectlon through the box on line 5 5- Fig. 4, to lllustrate the startin and stopping friction brake mechanism. ig. 6 is a fragmentary section through the box on line 6 6 Fig. 4, to-

illustrate the ratchet and dog locking device of the spring driving mechanism. Fig. 7, is

an enlarged fragmentary section through one of the clutch mechanisms. Fig. ,8, is a vertical longitudinal sectionthrough the box, the driving mechanism being omitted.

In referring to the of the improved machine illustrated in the merals designate like parts.

- The box 1 as shown has a lower sounding compartment 2 and an upper inclosing compartment 3 for the driving mechanism. The box top is composed of a fixed or stationary rear portion 4 and a movable front portion 5 which is hinged at its rear edge to the front edge of the fixed rear portion 4; said movable front portion forming a cover' anism and the other for the cylinder record mechanism are absolutely independent of each other and are supported from the fixed rear portion 4 of the top of the box. Said reproducing mechanisms are adapted to be preferred adaptation accompanying drawings in detail like nuswung manually by the operator into" and out of operating position with reference to the records.

The disk record mechanism consists of' a vertical shaft 6 journaled in a deppndin bracket 7 attached to and dependin eneat 1 the cover 5 and having its upper en rojecting l'oos y through an opening in t e said cover and a horizontal support or turn table 8 fixed to the upper proyecting end of the shaft 6 upon which the disk records are adapted to be placed in the usual manner.

. The reproducing mechanism for the'disk record mechanism includeera sound conducting tube 9 which is supported from the fixed rear portion 4 and has the usual goose neck l0 and a sound box ll arranged at the forward terminal of said goose neck which can ries the needle 12.

The cyllnder record mechanism is mounted on the cover at one side of the disk rec- 0rd mechanism and comprises a frame 13, a cylinder record supporting mandrel 14 journaled in said frame, a screw bar 15 for feeding the reproducer goose neck along the record an mandrel,.a small'pinion 19 mounted on said shaft. an intermediate shaft, 20, a centrally mounted spur gear wheel 21 on said shaft 20 which meshes with the pinion 19, two spur gear wheels 22 and 23 also mounted on the shaft 20 on opposite sides of the wheel-21, a slide shaft 2% connected to the feed bar 15 and two gear wheels 25 and 26 on said slide shaft adaptedto-mesh respec tively with the gear wheels 22 and 2.3 see Fig.1. 7 Y i he slide shaft 2 1 has anenlarged knurled head 27 at its outer end which is adapted to be grasped by the operator to slide a movable clutch member 27* attached to ,the inner end of the slide shaft. 24 into clutching engagement with either one of two fixed clutch members 27" and 27 which are respectively attached to the gear wheels 25 and 26 as shown in Fig. 1. The gear wheels 25 and 26 are always in mesh with the gear wheels 22 and 23 and are loosely mounted on the slide shaft 24 so as to rotate independently thereof except when clutched thereto by the movable clutch member 27 In Fig. 1 the movable clutch member is shown in clutching engagement with the fixed clutch member 27 attachcd to the gear wheel 25 and outbf clutching engagement with the fixed clutch member Q'F'attached to the gear wheel 26. The purpose of this mechanism is to enable the ratio of speed between the feed 'bar 15 and the mandrel.

1 1 to be varied or changed so that different styles of cylinder records may be played on the same machine. The cylinder record reproducing meehw;

nism is similar to the disk record reproducing mechanism; being located on one side thereof and it consists of a sound conducting tube 28 supported from the fixed rear portion 4;,- a goose neck tube29 .ivotally attached to the tube 28, a semi box 30 attached to the forward terminal of the goose neck tube 29 and a needle 31 carried by said i sound box.

The driving mechanism in the adaptation illustrated is-of the spring operatedtype.

Referring to Figs. 2 1 and 5, a spiral spring 32 is'incased within the two parts 33 and 3st of a two member cylindrical housing and is adapted to be wound up or placed under tension by a winding handle 35 (a fragment of the stem of said handle being shown in Fig. at) which is detachably fitted on the end of a shaft 36 journaled in hearings in a bracket 37 depending from the cover 5.

The shaft 36 is provided with a ratchet wheel 37 and a pivotal locking dog 38 is arranged-to engage the teeth of the ratchet wheel and thereby prevent the shaft 36 turning in the reverse direction or in a direction to unwind the spring. see Fig. (3.

A spur gear wheel 39 is mounted on the shaft 36 which meshes with a spur gear wheel 10 mounted on a short projecting;

shaft 11 extending from the outer member 34 of the housing. The housing member 3-1 is also provided at its outer end with a large spur gear wheel as which meshes with a small pinion 43 mounted on an intermediate shaft 14;, see Fig. 4;

At the opposite end of the intermediate shaft is arranged a spur gear wheel, 15 which meshes with a spur gear wheel t6 mounted on one member 417 of a clutch which is arranged on the driving shaft for the cylinder record mechanism.

The clutch member 17 is loose on the shaft 48 being free .to rotate independently thereon but is held against longitudinal movement thereon by one of the two frame members 4-9 and 50 in which the driving shaft 18 is journaled. The other or opposite member 51 of the clutch is also mounted on the driving shaft but is nnrotatably fastened thereon by a pin extending transversely from the shaft and projecting in a longitudinal slot in the clutch member 51 as shown in Fig. 3, which permits it to be shifted into and out of-clutching eugagement with the other clutch member.

The driving shaft 4:8 for the cylinder record mechanism is connected to the shaft 18 extending from the cylinder mandrel by a belt 5% which encirclcspulleys and 56 mounted respectively on the driving shaft 18 and shaft 18 shown'in Fig. 2.

A driving shaft 57 for the disk record mechanism is also mounted beneath the cover 5 shown in Fig. 1, and has a hovel gear, wheel 58 at one end which meshes with a bevel gear wheel 59 on the vertical shaft u.

A clutch similar to the clutch mounted on the driving shaft 48 is likewise mounted on the driving shaft 57 for the disk record mechanism and consists of two members GO and '61; the member (10 being slidably hut uurotatably secured thereon and the other member til loosely surrounding the shaft but held from longitudinal movement thereon. The member (31 is rotatable independently of the shaft and carries a pinion 62 which meshes with the spur gear wheel on the intermediate shaft 44. The slidable members of the two clutches are connected to a single clutch shifting mechanism for simultaneous operation. i

F or an understanding of the principal portion of the clutch shifting mechanism reference is to be had to Fig. 3. r A rock shaft 63 is journaled in brackets 64 and carries a crank arm 65 provided with a bifurcated end 66 which loosely engages in a groove 67 in the clutch member 51 and a bell crank68 which is connected at one end to the clutch member of the clutch controlling the operation of the disk record.

mechanism and at the opposite end to a toggle arm '69 extending from the rock 'shatt.

, From this construction it will be noted that v by the bell crank and toggle, thereby bringby rocking the shaft 63, the slidable clutch member 51 will be moved in one direction by the crankarm while the other clutch member is shifted in the opposite direction ing one clutch into clutching engagement and simultaneously therewith disengaging the other clutch.

The shaft 63 is rocked by meansof a turn button 70 arranged on the top of the cover 5 and having a depending stem 71 and a transverse arm 72 at the lower end of said depending stem which is provided with an opening (not shown) through which one end of ably fits. The arm 72 is balanced yieldingly on said rod 73 between two

springs

74 and 75 which are held in place on the rod by two' separated washers 76 and 77 and the oppo site end of said rod 73 is pivoted to a crank 78 extending from therock shaft 63. The purpose of the

springs

74 and 7 5 are to provide acspring tension on the rod in either drrectiun it is moved and thereby force the slidabl'e clutch member of the clutch that is being engaged into clutching position as soon as it registers with its opposed clutch member.

The speed of the machine is cont-rolled by a governor 79 of the ball spring type and said governor is regulated and adjusted to vary the speed by a turn button BOpro ecting from the top of the cover and having a stem 81 extendin through an opening in the cover; said stem being provided at its lower end with a cam 82 which is connected to the governor is a connecting rod 83.

the mac ine is started and stopped by the operator ttirnin athird button 84 mounted on the cover which controls a friction brake 85 ada ted to be enga ed with or dlsengaged i i-om a wheel 86 s own in Fig. 5.

The brake shoe 85 is pivotall mounted on one end of a lever arm 87 which is pivoted at an intermediate point to a bracket 88 and at its 0 posite end to the lower terminal of a verticairod 89.

loosely through aniopning 90 inthe cover 5 and into a recess in the button 84 and has a transversely extending portion 91 at its upper end which slidabl fitsfthrough .a cam slot 92 in the side-0 the button 84;. By

turning the button 84 in one, direction, the

rod 89 is lowered applying the brake and by turning it in the opposite direction the rod is raised disengaging thebrake.

A -spring 93 is mounted on the rod 89. beingheldthereon by a washer 94; the tendency ofsaid spring beingjto press. the rod 'downwardin a direction to apply the brake.

The operation of this improved machine is as" followsg -The spring of the driving mechanism'having been wound up by turning the-handle. 35 and a {record or records having been placed on one-or both the turn table 8 and the mandrel 14; the machine is started by turningthe button .84; in a direction to release the brake, the clutch shifting mechanism is moved to connect either the disk or the cylinder record mechanism with the dr ving mechanism by turnin the button'70 in the desired direction,"an the speed is regulated by turning the 'button 80. In this improved machine the-- disk and cylinder record mechanisms are entirely independent of each other and ar arranged so that they are operated from a single driving mechanism. 7

It will be understood that the foregoing mechanisms may be altered or varied within the scope of the following claims without departing from my invention.
