Application illsd March 5, 13-15.

To all w/l'm/i it may; concurs,

Be it lniown that L l'llms Elms, a citizen of the ll riled Slates, residing as Hancock, in the crumty of Pollawaitamie and State of Iowa, have invented certain new and useful Improvements in Gcarings for Phonographs and other 'lalking-lllacliines; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in he art to which itapperlains so make and use the same. 7

This invention compreheuds certain and useful improvements in gearing mechanism for phonogruphs and the like, and has for its primary object to provide improved and novel "caring between the more! and the governor or cone-rolling; the speed of rotation of the cylinder shalt and the horn.

supporting "zlie feeding shaft.

The invention has for another object to provide improved and novel gearing of the above stated dlfil'lClZGI' which will be especially adapted for operating cylinder shaft and the horn carrying; and feeding shaftautomatically coulrolling the speed of rotation of said shaft.

The invention has for a still. further object to provide gearing of the above stated nature in which the governor is mounted upon a shaft independent of the motor shaft and in alincmeut with the same, a suitable brake disk being carried by the governor for engagement with a brake arm to prevent the shaft of the talking machine from rotating too rapidly.

With these and other objects in view as will become more apparenlas the description proceeds, the invention consists in oer tam novel features of construction, combi nation and arrangement of parts as will be; hereinafter more fully described and claimed.

For a complete understanding of my invent-ion, reference is to be had to the following description and accompanyingdrawings, in which Figure 1 is an end elevation of the principa parts of a talking machine equipped with improved gearing, parts of the casing being broken away to show parts of the gearing, and Fig. 2 is a longitudinal vertical. section. through the same with nrv gearin; and she parts to which the gearing: is.

connected shown in elevation. said View Specification of Letters Patent. Pay;-

enl'ed May Serial No. 12,452,

being taken substantially on the plane of line ill-2 of Fig. 1.

Referring in detail tolwhe drawings by numerals, l designates the spring motor sbr' 'r. having a spring motor 2 of conve11- lional lorm mounted thereon, while a crank arm 3 ismouuled upon the outer end of said shaft 1. it will be understood phat the shaft 1 is mounted in suitable bearrugs l within the casing or body 5 of the phonograph or other talking machine and a belt 8 is around a suitable belt wheel '7 mounted upon the shaft 1 and also around a belt wheel 9 mounted upon. the horn carrying and guidingshaft 10, which is mounted in suitable bearings 11 projecting upwardly from the top of the casing or body 5, as will be readily understood by referring to the drawings.

I; will be understood that the horn supporting and carrying: arm 12 is mounted at its lower end for longitudinal movement upon the shaft 10, while the reproducer 13 is mounted upon the opposite end of the arm 1.2 for engagement with a cylinder 14 engaged upon the cylinder mandrel 15 mounted upon the cylinder shaft 16. It will also be understood that the born 17 is secured to the reproducer 13. in any suitable manner.'as shown at 18, and a downwardly directed arm 19 is carried by the arm 12 for engagement upon a supporting and guid ing shaft 20 between the shafts 10 and 16 and preferably in a plane abovethe same, as will be readily seen by referring to Fig. l of the drawings.-

A large gear wheel 21 is mounted upon the shaft 10 and meshes with a gear wheel 22 somewhat smaller in diameterthan the gear wheel 21 and mounted upon the cylinder shaft 16. The gear wheel 21 also meshes with an idler or intermediate gear wheel 23 mounted upon a stub shaft-24, which idler gear wheel 23 also meshes with a similar gear wheel 25 and below "the same and mounl'ed upon a s'lub shaft 26.said idler gear wheel 25 being somewhat larger in diameter than the first mentioned idler gear wheel 23. Beneath and meshing with the idler gear wheel 25 is a gear wheel 27 which is mounted upon the governor shaft 28 and the gear who 27 is preferably smaller in diameter than the gear wheel 25. The purpose of the dillerence in diameters of the various gear wheels will be readily apparent. as the extended different shafts may be rotated at different speeds.

Thegovernor shaft 28 has one end mounted in a suitable bearing 29 inthe end of the casing or body 5, while its opposite end is mounted in a stationary bearing bracket 30 projecting upwardly from the bottom of the body or casing 5 and the governor shaft 28 is preferably in alinement with the motor shaft 1. a

Secured to the governor shaft 28, preferably at the inner end thereof, is a collar 31 to which the inner ends of the resilient governor arms 32 are connected, while the outer ends of said governor arms 32 are secured to the circular flange 33 projecting from one side of the brake 34 which is' loosely mounted upon the governor shaft 28 a spaced distance from theouter end thereof.

It will be evident that as the speed of rotation of the governor shaft 1 and the shaft of the talking machine increases, the governor arms 32 will move outwardly with the blocks mounted thereon, preferably at the longitudinal center of said arms 82, as shown at I 36, by rivets or other suitable securing members. As the speed of rotation of the governor shaft 28 is unduly increased, the inner face of the brake disk'34 will be drawn against the brake face 37 of the stationary depending brake arm 38 which has its upper end turned at right angles, as shown at 39,

and secured to the top of the body or casing 5, While the lower end is turned outwardly, as shown at 40, and provided with the brake face 87, previously mentioned. This frictional engagement of the brake disk 34: with the brake faceB'Z of the brake arm 38 will immediately decrease the speed of rotation of the governor shaft 28 and likewise cause a'decrease in the .speed of rotation of the meme? out departing from the spirit and scope of the invention as claimed or sacrificing any of the advantages thereof.

'What is'claimed isz- In a talking machine, a casing, a drive shaft mounted in said casing, a motor for driving saiddrive shaft, a horn supporting and feeding shaft mounted on the top of the casing, connections between the motor shaft and the horn supporting and driving shaft, a cylinder shaft, gear wheels on the ends of the horn and driving shaft and the cylinder shaft, said pears meshing with one another, a stub shaft journaled in one sideof the casing, a gear on the'end of said stub shaft, a governor shaft, a governor mounted upon the governor shaft for controlling the speed of rotation of said shaft, a gear the on the end of the governor shaft for meshing with the gear of the stub shaft, said stub shaft gear meshing with the gear of the horn supporting shaft and means for controlling the same.

In testimony whereof I 'afiix my signature in presence of two witnesses;

HANS F. NEVE.
