MOTOR FOR TALKING-MACHINES.

Original application filed June 21, 1898, Serial No. 884,052. Divided and this Ro.173,060.

Specification of Letters 'Patent.

Patented March. 6, 1906. application filed September 14, 1903. Serial To all whom it may concern:

Be it known that I, Emerson R.Jonsson of the United States, and a'resident of the city of Philadelphia, State of Pennsvl- Vania, have invented certain new and useiul Improvements in Motors for Talking-Machines, of which the following is a full, clear, and complete disclosure.

My invention relates to certain improvements in spring-motors for talking-machines andhin the gearing used in connection therewit The object of my invention is to provide an improved arrangement of the arts of the motor and its connection with t a drivingspindle of the talking-machine such that the action of the motor Wlll be uniform arid constant and such that the driving-spindle will be driven noiselessly without undue friction, while at the same time the use of a large number of delicate and complicated parts is avoided.

With these and other objects in view my invention consists in the construction, arrangement and combination of parts hereafterfully described in the following specification, and particularly pointed out in the claims annexed thereto, this ap lication being a division of my rior app ication, filed June 21, 1898, Serial 0. 684,052.

For a full, clear, and exact descri tion of my invention reference may be he to this specification and to the accompanying drawin forming a part thereof, in whichrgure I is a vicw'showin the main parts of my improved motor in c ovation certain portions being shown in section and broken away; and Fig. 2, a plan view of thesame, the top of the casing and the turn-table being removed. V

In the drawings the numeral 1 indicates an outside box or casing on the top of which is a. cover 2, whichis attached to the side of the casing in any suitable way, but is referably hinged thereto. A horizontal sha t 3 is provided at one side of the motor havin bearings 4 and 5 in the sidewalls 6 and 7 0 a suitab e sup citing-frame; the extending and of i said sh t 3 also having a bearing in a plate 8, attached to the insideiof the side Wall of the casing 1. A gear-wheel 9 is rigidly mounted on the shaft 3 and meshes with asmaller ear wheel 10, rigidly mounted on a stub-sh .1 1,

- theu ing the latter securely lower end of with a pinion 29-, rigidly secure p j ournaled in the sideof the casingl by means of the late 12. The outer rojecting end of the stu shaft 11 is reduced or the reception of a crank-handle 13, which is provided with a slot 14, adapted to engage a pin 15 on the stub -shaft 11. B means of this crank power is transmitte to the shaft 3 for wind mg up the spring or spri s which propel the motor in a manner hereina ter to be described. Loosely mounted on the shaft 3 between the two side walls6 and 7 of the sup ,ortingframe is a drum 16, having attached to the interior thereof a s iral or coiled spring 17, the other end of which is secured to the Winding shaft 3. Rigidiy attached to the windin shaft 3 is a ratchet-wheel 18, which is a opted to be engaged by a pawl 19, fixed to the side plate 7 of the motor-frame. This pawl 19 1s pivotallyfixed to said plate and may be operated by ravity or by a spring as ma be desired. Ihis ratchet and pawl may a so be located in any other convenient position-such for instance, in connection with the stub-shaft I1. Upon the c 'lindrioal surface oi the drum 16 is provide gear-teeth forming a wormwheel 20, which is adapted to mesh with a worm or screw 21, carried by the turn-table s indie 22. The turn-table spindle 22 is in t e form of a vertical shaft having bearings 23 and 24, which are re'ferabl antifrict'ion or ball bearings whic not on y guide but support the weight of the shaft 22 and the turn-table 25, carried thereon. I have shown per 'ndof the spindle 21 as being redues in diameter and screw-threadcii to receive a thumb-nut 27, which may be screwed downward onto the record, thereby clampin pbsition. plicity the turn-table is shown. withoiit the record being mounted thereon. On the the spindle 22 is rigidly secured gear 28, which is ada ted to mesh don the lower This gova large end of the governor-spindle 30.

ether-spindle 30 has bearings in the motorframe at its upper aiid lower ends and carries on its lower, portion a sleeve 31 For simslidahly' mounted thereon and having at itp lower end a disk 32, which forms one element of the governorbrake. The usual adjustable brakeshoes are designed to cooperate with this disk, but are here ness.

omitted for the purpose of .clear- While I have "shown and illustrated one 7 sprin on the shaft 3 for driving the drum 16, it wi of course be understood that two or more springs may be used, the only necessa changes in that case being to provide a sha t combination of a vertical driving-spindle, a

worm carried by said spindle, a driven member mounted on said spindle, a drum having aworm-gear on its, outer surface and meshing with said Worm, a horizontal windingshaft upon which said drum is mounted, a spring connecting said shaft and drum and a centrifugal governor'for controlling the speed of saidspindle. i

2. In a motor for talking-machines, a horizontal winding shaft, a drum revolubly mounted thereon, a coiled sprin connecting said drum and shaft, said drum aving gearteeth located upon its cylindrical surface and forming a screw-gear, a vertical turn-table spindle, and a screw-gear mounted on said spindle and adapted to mesh with the teeth upon said drum. 3. In a motor for talking-machines, a horizontal winding shaft, a drum revolubly mounted thereon, a coiled sprin connected with said drum and shaft, said rum having gear-teeth located centrally upon its cylinrical surface and forming a screw-gear, a vertical turn-table s indle and a screw-gear upon said spindle a apted to mesh with the teeth upon said drum.

4. In a motor for talking-machines, a horizontal winding shaft, a, drum revolubly mounted thereon, a coiled sprin connecting said drum and shaft, said drum having gearteeth located upon its cylindrical surface and forming a screw-gear, a. vertical turntable spindle, a screw-gear mounted on said spindle and adapted to mesh with the teeth upon the drum, and a centrifugal governor driven directly from said vertical spindle.

5. In amotor for talking-machines, a horizontal winding-shaft, a drum mounted thereon, a coiled sprin connected with said drum and shaft, said cated centrally upon its surface and forming a screw-gear, a vertical turn-table spindle, antifriction-bearings for said spindle, a screwgear upon said spindle adapted to mesh with the teeth upon said drum, a gear also carried by said s indle and a centrifugal governor operated y the last-named gear.

In Witness whereof I have hereunto set my hand this 11th day of Se tember, A. D. 1903.
