. To all 'whom it may concern:

Be it known that I,W1LL1AM S. PERRY, a citizen of the United States of America, and

-a resident of the borough of Manhattan, city,

county, and State ofNew York, have invent-' ed certain new and useful Improvements in Talking-Machine Motors and Governors, of which the followin isa specification.

My invention re ates generally to s rin driven or other motors, and more spec' calfy consists of an improved form of smoothlygoverned spring-motor designed for use in talldng-machines.

M lnvention has the additional purpose of prodiicing such motor and governor at small cost.

The best form of apparatus embodyin y invention at present own to me is trated-in the accompanying three sheets ofv drawings, in which- Figure 1 is, a plan view of the base-plate of the motor with arts showingonf'the u per side thereof. 2 is a bottom view the same. Fig. 3 is a sideelevation; Fig. 4 is a detail sectional View showing the governor governor-adjusting handle. Fig. 6 is a detail perspective view, with parts broken away, of

- the-governor-adjusting device; and Fi 7 is a plan view of the goyernor-adjusting evice with the handle removed. v I

' Throughout the drawings like referencee movable lengthwlse of the governor-shaft by 80 figures indicate like parts.

8 is made integral with orconnecte 45 1 is the base-plate, in which is journaled the vertical shaft 2, canryingtherotating ta- Shaft 2 has ball-bearing'3 or other proper bearing on the base-plate.

4 is a spiral spring, the inner end of which Fig, is a .detail view of the the pinion 8 thereto in one direction. .The gear 10 meshes with the pinion 11, and by the above-described train of gearing the unwind- 5o ing action of the spring-is transmitted to the shaft 2.

On the lower end of shaft 2is mountedthe. worm-wheel 12, which meshes with the worm 13 on the governor-shaft 14-. This governor- 5 5 shaft is carried in suitable bearings (shown clearly in Figs. 2 and 3) and has the two opposite oblique projections 15 15, which are lnclined at the same angle to the shaft. On these projections are, mounted gevernor- 6o weights 16 16, normally forced inward towardthe governor-shaft by the springs 17 17 When these governor welghts are made of conical shape, as shown, the supporting projections 15 15, on which they are mounted, 6

\ These. weights 16 16 are wedge-shaped and are, preferably made in the form of cones, as 70 shown, as this the'cheapest form of wedge and the one bestada ted for my purpose. These cone-shaped weights 16 16 or one element of the cone-surfaceof each are adapted to come in contact with the friction- pad 18, 75 which preferably is made in annular shape, surrounding the governor-shaft and having its surface a plane at right angles to the axis of said governor-shaft. I This friction-pad is reason of its mounting on the baselate. This mounting consists of a rectangular ange 1 9,1cut away at 2 0 and guided by lugs 20 20, entering said opening 20. This fr1ct1onpad mounting is" therefore ca able of movement 8 by reason of the aboveescribed cut-away portion 20 and the opening 1 1n the base. plate, through which'itextends. Further engagin this 0 ening 20 1s theeccentrrc 21, mounte on t e pivot-screw 22 and con- 99 trolled b the handle 23. The inner end of the hand e 23has a suitable number of notches 24 formed therein, *with which the lockingspring 25 engages,-as clearly shown in Fig. 1.

- The winding mechanism consists of the gear-wheel 26 on the upper end of the shaft 9 which is provided with a series of radial gearteeth 26 and a series of crown ear-teeth 26", the crownteeth being space radial teeth 27 and crown gear-teeth 27 Gear-wheel 27 is mounted on shaft28, which isjournaled in is forced out disen a in t e same.

. I g g bearings 29, and has a cross-pin 31', with which the winding-key 32 may engage when the collar 35 is forced back sufficiently against the resistance of the spring 34. The other end of the spring 34 rests. ,against the collar- 33, held in place the pin 30, also passing through the shaft 28. v Themethod of operationof my invention is as follows: The's ring being wound up by the winding-gear, t e parts being in the rela" weig ts 16 16 away from the shaft wedges them down upon the friction-pad 18 until between the" radial teeth. -This meshes with another. gear-wheel, 27', having further increase of speed is checked. It is.

evident that adjustment of position of the friction-pad will vary the speed in the usual way and that when the same is forced up to its imiting position the governor, and consequently the clockwork of the motor, will be locked against all movement. If the friction of the cones 16 '16 on their supporting projections 15 15 is not too great, the cones will tend to rotate on said projections, and thus have a combined slidin and rollin motion over the face of the frictlon-pad. T is I find to produce a more even frictional resistance than is produced when the wedge-shaped bodies are incapable of rotation.

" The advantages of my invention comprise the smoothness and accurac the governor and its simphcity and great cheapness of construction and the com act form of the motor mechanism as a whol e.

It is evident, of course, that various changes could be made in the details of construction shown without departing from the spirit and scope of my invention. The governor might be used to advantage in other forms of spring motor. Other means of mounting the riction-pad and regulating wedge-shaped governor-weights or slidable i bodies inig it be substituted for the cones shown without departing from the wedge principle of action; but these and similar mechanical modifications I should stili consider within the scope of my invention.
