Be it known that I, RAYMOND S. DnvNnY,

Va citizeniofthe United States,`residi ng at by reason of certain speed-increasing vgearing, serves to actuate the agitating means within the churn body at increased speed, and at the same time winds up other parts for the immediate application of the weight again, upon the completion of a full downward vvpassage of the same, so that the operation of thek motor is practically acontinuous one.

.A further object to provide aimachine l havin@ the above characteristics which ma be readily changed for operation by vhand or to be operated automatically, and wherein a prime desideratuin has been to construct the, several parts as economically as. possible in .order to render the same capable of being manufactured at a low cost..

- A. full yand complete Vunderstanding of the invention may be obtainedfrom a considera;l tion of the following detailed description,

Y taken inconnection withthe'accompanyingY drawing forming a part-of this specification; it beingunderstoodthatl while the drawing Shows a practical form of the invention, the latter is'not confined to strict conformity therewith, but maybe changed or modified, so long as such changes. or modications mark no material departure from the salient features of thev invention, as specifically pointed outin the appended claims. v

In the drawing, in vwhich similar reference characters designate correspending parts througlioutthe several figures Figure 1 is a, front elevationV ofl the improved motor for churns,l some of the parts being showny in section. .V-Fig. 2 vis a horizontal sectional view,v taken on the line 2,-2'of Fig. 1,-.and Fi-g, V3, is a side elevation vof the lower'portion of the'V machine. i

The major, portion of the herein described machine,in accordance with the stated object to constructthe same with rigid adherence to economy, is formedof wood of the proper kind, it being foundl that the latter-material has the advantage of combining the necessary strengthy andv lightnessjand lending itself admirably to structures of this character. 4 'i YA .supporting framework provided comprising a pair ofspaced uprights 1 1, which are appro riately connected'to base sills 2%2,'adaptec to rest upon the floor or other support, and thesaid ,uprights are furthersupported in upstanding position by inclined braces 3 3, arranged in pairs Y and connected to eachv upright, as-by pins 4 4, and adapted to rest upon said iioorin front and in rear ofthe same,and thus preventing any tilting movemen't ofthe uprights, as clearly shown in Figz vof the f drawing.

, The uprights l:-1are connected, adjacent i to theirtop ends,pby av crossubeam 5-which,

like the uprights, the base sills andthebraces, may be formed of wood and @is suitably secured to said uprights bymetallic brackets y 6-6 bolted or otherwise fastened tothe i said b e'am and uprights 'lhe c ross beam 5 is provided ata central point with a groove lor slot ZieXtendingfroni line of thesame,for a purpose to be ex-` one edge thereof to the longitudinal center plained, and is 'furthermore adapted to support a pair of brackets 8 and 9 respectively, in the form of castings, arranged in spaced relation to the said slot and suitably secured f' .to the beam as by screws for bolts. bracket 8 comprises a baseportion for at-y tachment to the beam and has 'ani overhanging prntiony 10 adapted to overlie the slot 7 and provided witha socket 11 `in its lower facev in'alinement with the said slot; The

The i' said bracket 8 'also has an upstanding 'arm .12 located overthe socket 'and provided with a transverselydisposed bearing opening 13', which is `in horizontal alineinent" with a similar bearing opening 14 provided at the upper end ofthe other bracket 910e cated at the opposite side of the slot'7 1 rllhat upright or standard 1 located nearer to the bracket 9 vis provided with abearing opening 15 Vabove thebearn, iand in aline: A

vinent- `with the aforesaid.bearings"13y and 14, and through thesey several .bearingsis adapted'to be passed a horizontal shaft 16 which Vconstitutes a: power. shaftr 'when the i y v Y device isarranged to be driven by hand, as

through the medium of a hand crank 17, indicated kin dotted lines in Fig. 1 of the drawing.'

A crown gear wheel 18 is vsuitably secured' to theshaft 16 between the brackets'8 and 9, the teeth ofl said wheel facing toward the slotV 7, and a pair of spools 19and20 are suitably mounted to rotate with the shaftv 16 and arranged adjacent to the bracket 9 for the purpose of vconnection with the weight-driven mechanism toibe later described.

-A rectangular churn-body 21 of any desired capacity and l.formed of. vsheet metal, wood or Crockery-ware -is located/beneath thebeam 5, .the center of the same being normally in vertical alinem'ent with the socket 11 andthe Vslot 7. The churn-'body 2f1-is adapted to be supported by 'a pedestal 22, V,suitably ysecured thereto andl resting upon a base 23supported by the lioor. `Thev base 23 carries an upstanding pin 24 entering a suitable seat formed in the lower end of the pedestal 22 and.serves'toprevent any lateral movement 'of the churn-body and l pedestal 'relative tothe said base; AThe base f and pedestal maybe formed ofiwoodand are preferably provided with suitable antifriction means, such as ball-bearings 25 to support the weight'of thechurn body and its contents andfreduce the friction of the Y bearing vto a minimum.

VvThe churn-body 21 is provided with a suitable'lid '26, hinged asv at 27'to the rear edge of said Vbody andv having. suitable clamps 28 for holding the same in position during the revolving motion of the body,.and also-provided with a-sight opening v29 for the purposes of observing the progress of the churning operation.

Y A metallic tubular post 30, having an enlarged base portion 31 suitably secured to the center of the lid is adapted'to extend gear 18. Y

upwardlyand through the slot 7 formed in the cross beam 15,' and is provided at'its upper end with. a horizontally disposed gear wheel 32 preferably'formed integral therewith and normally lying vin meshing rela'- tion with the lower portion of the crown the tubular sleeve 30 from its position in the slot 7, a locking member 35, formed of suitablespring wire is secured to the beam y 5, vas at `36, at one side ofthe said slot-7 and extends across the latter and is adapted to Vengage behind an upstanding4 pin 37v located on the upper face of the beam 5 and 'thus surround the tubular sleeve 30 and confine the latter within said slot-7.

The shaft 33 carries at its lower end a dasher-hub 38 provided with a'pluralityiof paddles 39y having the perforations V40 Vfor permitting the passage ofthe milk within the churn-body 21,*the said Vhubl38 `being detachably connected 'to the shaft v33 by a set-screw 41. 1 f* The construction and operation vof. the .Y hand-driving means will be Vvreadily'understoodfVVhen it is desired to churn a quantity of milk, the churnbody21 is removed from the frame of the machine, and the milk is placedwithin'the body, the lid 26 lbeing thrownvback upon its vhinges for the purpose: Then the dasher is secured upon the inneror lower end of the Vshaft 33 through the medium v of the set-screw 41:

Next the lid is closed and locked upon the churn body 21 by means ofthe clamps 28,

and the dasher and shaft are allowed to drop when the dasher will yrest' upon the bottom of the churn-body, and the top ofthe said shaft 33 will project only slightlyabove the gear wheel 32, free to Vpass beneath the overhanging portion 10'of the bracket 8. Upon sliding the churn body together'with the base 23 into position, the Vshaft 33vmay be elevated into position within the socket A11, yand be secured therein by the set-screw 34v and thespring lock 35 engaged around thetubular sleeve 30. In order to adapt the machine for weightdriven means, the upperv ends ofthe uprights 1-1 are each provided with mortises 42, into which are adapted to 'be Vfitted corresponding portions of extensions 43 which are of sufficient heightv to provide the necessary fall for 'the purpose designed. The

upper ends vof the extensions are Vvprovided with ball-bearing socket members 44-a`dapt ed to receivev the end portionsof a horif zontally disposed shaft 45, preferably formed of a wooden bar, round forsjthe major portion of its length and having r a squared portion 46'arranged over ythe shaft 16, said squared portion having secured thereon, a pair of relatively largesheavesr 47 Aand 48, locatedy respectively overY the spools 19 and 2O and-,connected therewith f with reverselv wound strands 49' and V50 respectively. ach of the strands 49and 50', which may be of some suitable, strong, flexible cord or rope,- are substantiallysequal in length to the heightl of Vthe shaft 45 Vabove i the floor or support, `'and while themajor portion of one strand 'is wound upon the proper sheave in onedirection, thel major portion of the other strand is wound upon its proper spool in the "other'direction', so

that when a revolving Vmotion is imparted to the top shaft 45, in a manner to be described, it will readily be seen that one of the strands 49 or 50 will tend to rotate the shaft 16 in the same direction, whileV the other strand will be wound up upon either its sheave or spool, and in the opposite direction ready for the next operation of the device. Y

In order to impart rotary motion to th shaft 45, a pair of relatively small spools 51r and 52 are mounted upon the squared portion 46 thereof, near the adjacent extension 43 and have reversely wound thereon strands located at the top of the machine, that the oothe churn.

shaft v45 will be rotated in a direction ,depending upon the direction of winding of said strand, and that the shaft 16 will be correspondingly rotatedby means of either the strand 49 or 50, and. that the reverse of the operation is obtained by every alternate engagement of the weight 56 with the strands 53 and 54, so that practically a con# tinuous operation of the machine may be obtained by merely changing the said weight By reason of the rectangular formation of the churn-body, the entire contents of the same is thrown against the stationary paddles 39, the perforations 40 formed in the same permitting the passage of some of the milk and resulting in the rapid breaking up ofthe fat cells therein, and the quick pro-A duction of butter. Y

The following are the steps necessary to obtain access to the interior of the churn to remove butter therefrom, and clean the dasher, etc. First, the set screw 34 is loos-Y ened, which will permit the shaft 33 and its dasher to drop to the bottom of the churn. Then the latch 35 is disconnected, where# upon the sleeve 30 with .its gear may be moved outwardly -through the slot 7 and the churn itself with its base may be moved out of the way of the framework. Then the llatch `means 28 may be disconnected. The shaft -33 should now be pulled upwardly to bring the dasher 39 up against the under side of the lid 26. The lid may now be swung open without interference of the dasher withthe4 sides of the churn, by taking advanta e of the rectangular shape of ith the lid once swung open, it is easyy to disconnect the set screw 41,

whereupon thefdasher may be removed from its shaft and the contents of the churn itself e may be removed.

.Obviously, my improved motor mechamsm maybe used to drive or rotate other things than churns, and while a churn has been described in some detail in connection A with the invention, I do not wish my invention to beV considered as being limited to such use.

Whatis claimed is:-

1. The combination with spaced uprights, an intermediate cross beam connect-lng the,

uprights, a body mounted for revolution between the .-uprights and having a-closure, a spur, ge-ar carried by the closure and having a bearing in the cross beam, spaced brackets carried by the latter and having horizontally alined bearings, a counter shaft mount-A ed in said bearings and adapted to receive a hand crank and carrying a vcrown gear in normal meshing relation with the spur gear,

a stationary shaft secured against rotation Y in one of the brackets andextending into' the body7 a .pair of spools mounted onthe i countershaft, a shaft mounted fat the top of the uprights and having a'pair of sheaves in alinement with the saidl spools, strands reversely wound upon the sheaves and connected with theV spools on the countershaft,

a second pair of spoolsmounted on the topf shaft and having reversely wound strands arranged thereon, and a weight for alternate kconnection to the last named strands for actuating the machine.

2. The combination` with a gear-supporti ing frame-work including spaced upright i standards carrying gearing including a pair Y of spools and a gear, a body mounted for rotation between the standards, a shaft extending within the body and secured against rotation to the frame-work, a gear carried i by the lid of. the body and adapted to be placed in vmeshing lrelation with theg'irstnamed gear, a shaft mountedat the top ofthe standards and having sheaves, strands reversely wound upon the same, and alternately extended and connected to the spools, a second pairof spools carried bythe shaft and having strands secured thereto for alternate reverse windingv thereon, and a weight for alternatey connection to thelast-named strands. e i

In testimony that I claim the foregoing as my own, I have* hereto affixed my signature e in the presence of two witnesses.v
