.' l'o all whom it may concern:

Be it known that I, GEORGE WASHINGTON STILES, a citizen of the United States, ,residing at Smithmill, inthe county of Clearfield and State of Pennsylvania, have invented certainnew and useful Improvements in Churn- Motors, of which the following is a specifica-I tion. v.

This invention relates to chu rn-motors andl it has for its object to provide an improved mechanism of this class which shall be superior in point of simplicity, positiveness of cperation, andgeneral efficiency.

In the drawings, Figure 1 is a side elevation of .my improved churn-motcnv-showing the churn in operativel position, one side of the casing being removed to better'llnstrate the construction. Fig. h2 is a detail vertical transverse sectional View taken upon the line fr Fig. 1, and showing the spring-actuated operating member of the motor. Fig. 3 is a top plan viewof the same.

Corresponding parts in all `the figures are Referring to the drawings, 1 designates my improved chnrnmotor, which comprises a spring-actuated operating member 2 and a churn-cradle 3,'which is operatively connected with/the operating member 2 and upon which thechurn proper, 4, is given the required oscillation or rocking movement. The entire motor is preferably supported upon a snitable base or table 5, which may be provided with legs or standards 6. The spring-actuated operating member 2 may be housed in a suitable casing7, which is mounted upon one end of the table 5, and the cradle 3 is mountedy upon the other end of the table in front of In the preferred form of construction the cradle 3 consists of a horizontal frame 8, which is supported by short uprights 9 upon rockers 10, and the rockers t between longitudinpon the top of the table and at opposite sides of the same. The cradle is provided at the end adjacent the casing 7 with anupright fixed arm 12, by which the cradle maybe os-lcillated. Operative connections, as at 13, extend between the xed arm `12 and the'oper ating member 2.

In the preferred form of construction the- Serial No. 61,850. (No'model.)

spring-actuated operating member 2 consists of a main spring-driven shaft 14, a supplemental spring-driven shaft 1 5 in operative connection with the same, and a crank-shaft 16 in operative connection with the supplemental shaft 15. The operative connections 13 extend between the crank-shaft 16 and the fixed arm 12, carried by the cradle 3. The shafts 14, 15, and16 are arranged in a vertical series, the shafts 14 and 16 occupying, respectively, the lowermost and uppermost positions-and lthe shaft 15 occupying the intermediate position. The operative connections 13 between the cradle 3 and the crank-shaft 16 consist of a `pitman `or connecting-rod 17,

one end of which is connected with the upper end of the upright arm 12 and the other end of which is connected with acrank-elbow 1S,

which is formed in the crank-shaftl. The crank-shaftl is also provided with a iiy- Wheel 19. The shafts 14, 15, and 16 are arranged transversely of the casing .7 and are journaled at their ends, as at 20, in side mem-- bers of the casing.

Loosely mounted upon the shaft 14 is a gear-Wheel 21, and loosely mounted upon the 'shaft 15 is a gear-wheel 22.' The gear-wheel 22 meshes withv a pinion 23, which is fixed upon one end 'of the shaft 16, whereby the rotation of the gear-wheel 22 causes the rotation of the crank-shaft 16 and the consequent os-V cillation or rocking of the cradle 3 through the medium of -the fixed arm 12 and the connecting-rod. A spring-drum 24 is coiled about theshaft 14, one end of the same 'being connected with' said shaft 14, as at 25, and the other end thereof being connected with the gear-wheel 21, as at 26. This spring may be considered both as a prime mover and as a reservoir of power after ithas been Wound up, as will be hereinafter more fully explained. A ratchet-disk 27 is fixed to the shaft 14 at any convenient point clear of the other mechan ism, and apawl 28, which is carried by the casing 7, operates Vin connection with the ratchet-disk 27 to prevent rotation of the shaft1 14 in one direction.l vided at one end with a crank 29, having a handle 30, whereby the crank may be operated to wind up the spring-drum 24 upon the The shaft 14 is also protoo shaft 14. The gear-wheel 21 meshes with a pinion 31,1xed to the shaftl. A springmentum to the churn 6 5 oneend against the fixed .weaker construction, is coiled about the shaft 15, and one end of the same is connectedwith the 'gearwheel 22, 'as' at 33, the other -end thereof -being connected with'the shaft 15, as

at34. This spring,'although one' which imparts motion to thespeed of the churn,

Io as supplementary to and not the equal ofthe spring 24 on shaft 14 Each of the springdr-,ums24 and 32 is inclosed between'its respective gearwheel 2l .or'22 yand a sp'idershaped '-cage 35 an'd 36, respectively, which cages consist of a plurality of-rad'ial arxns'37, which are connected at their outer ends with the .respective gear-wheel'sandfat their inner ends with hubs 38, which are vrevolubly mounted upon the respective shafts lffand 15.- zo vThe relative arrangement and construction '.of'par'ts'are such that-when the spring-drinnl 24 is-wo'und upby means f..th'e crank 29 it itis really the and'.. regulates causes, lthrough the revolution ofthe gear 21v and pinion 31,:the' re/volutlon ofthe shaft 15.

va 5 vin the proper direction to wind up the springf drum 32 upon said shaft 15. The-shaft 14 is prevented-from counter revolution by the.

pa'wl 28 and ratchet-disk 27, and during such windinga' hand held on they churn proper 3o prevents the revolution of thezcrank-shaft 16. The Wind-ing up ofthe spring-drum 32 being completed and the restraining-hand removed,

the tension vcauses the rotation of vthe 'gear-1' wheel 22, vwhich'in turn,through the medium of the' pinion 23, v'causes the revolution of the crank-shaft 16 and the consequent rocking of 'the cradle 3 and the churningof thecontents -of= the chnrnproper, 4. 'The momentum of the iiyLwheel- 19 causes apositive and steady 4o movement of the parts.

r 1 I have found the following relative sizes and proportions to be useful in arrangingmy two s pring-drnms andV attaining the best results in com bination but vthey are not arbitrary, Let

', .45 both springs be ofthe same thickness or gage of metal. Make spring 24 two and one-half inches wide and forty feet long, but let spring f 32 be only .one inch wide'and fifteen feet long.

4 This would provide forapproximately twenty-- 5o four turns of thecrank to completely wind up ,the large spring and would enable the'small- 'A spring'to communicate such power and moas would give approxi- .niatelytwo thousand' nine hundred and eighty 54 strokes. by -one winding of the large spring.`

Thechuin proper,4,n 1 ay readily be removed .fromthe cradle 3 for 4the pnrposeof filling,

ranged trans'vers'elyof the'end of the cradle must be consideredspring 24 canibe the communicated `be locked againstv 'without strain,

'y vienes opposite that with which the-fixed 'anni 12 is' connected.

.The operation' and advantages of my improved churn-motor will. be rv adily understood by those skilled in the art to whichit app'ertains. When the churn proper is in its poiv Vsitionupon the cradle Sand the crank 29 has been operated. to Win'd up the'springLdrum 24 winds up the spring-drum 32 and rotates the crank-shaft 16 and the consequent4 rocking of n pon the shaft 14,'-the gear-wheel 21 causes the rotation of the shaft -15, which in turn the c radle13 toperform the churning opera- I tion.

The' gear.- wheel 22 is thus rotatedl th'roughthe medium ofi-the spring-drum 32,

' and it results that the spring-drum 24 in running down orimparting energy to the springdrum 32 winds the 'latter 'nptoa considerable extent aswell as rotating' the gear-wheel 22.

-This surplus of energy after the spring-drum 24 becomes weaker than the spring-drum 32 causes the shaft 15 to'revolve in a direction the reverse of that in which'it revolvesunder the expenditure of the energy of the springdrum 24, and thisreverse"l movement of the shaft 15,l causes the gear 26 to revolve in such a direction that the spring-drum '24 becomes partially wound up'again. Inthemeantime the energy of the spring-drum`32 is also exshaft 16. .When the spring-drum 32 becomes weaker than the spring-drum24, the energyaccumulated by the spring-drain` 24 exerts itself to rotate the 'gearfwhee'l 22 and the shaft l-intheinitial'direction and again wind u-pthe springfdrum 32to con'tinuethe rotation of the ...crank-shaft 15,.as before. It willbe noted thatlthis' continuous alternate" winding and unwindingof the spring-drums24 and 32 causes a verted to 'continue the revolution of the .crank- ICI IIC

When bothof, the spring-drums reach the v state'in which they can no the resistance of the mechanism, the crank9 lis operated `to again wind up the spring-.drum

24 as initially and recommence the churning operation. The 'relationof thesprings may longer overcome ,be further explained by stating vthat the l wound'up to vits fullvextent evenwhen the shaft 16.is being revolved by shaft 16 may be held fast wound up to its full extent, which being jac- `eomplished it will-be found thatspring-32 has up to its full` extent, 'but small spring commences' to weaken.` Then' operation', w hile 'spring 2 4 practically remains inactive 'until the 'the large spring operates.y to rewind the' small l one, and

so the shaft 16has always' the full benefit of thecoperation of both springs.'

The relative arrangement of parts in whichy the casing7and the spring-actuated member 2 are arranged at one end of the table 5 and the cradle 3 and the churn proper, 4, are arranged at the other end of the table 5 is superior in point of compactness and convenience. The churn-cradle 3 oscillates in a path longitudinally of the table or support 5 and is prevented from lateral displacement by the cleats 11, arranged upon the top and at the sides of said tables.

I do not desire to be understood as limiting myself to the details of construction and arrangement as herein described land illustrated, as it is manifestl that variations and modifications may be made in the features of construction and arrangement in the adaptation of the device to various conditions of use without departing from the spirit and scope of my invention and improvements. I therefore reserve the right to all such variation and modification as properly fall within thel scope of my invention and the terms of the following claims.
