o it known that I, Samoan A. Hrson, a ii of the United States, residing at in the county, of Summit, State of ha e invented-certain new and usemul'tancously driven by a novel gearing argeinent, which is supported on the cover oif the receptacle whereby a high speedof rotationmay be imparted to the dashers with decreased wor ring power to more quickly convert the cream into butter.

llith the above and-other objects in view, the invention resides more (particularly in the peculiar combinations an arrangements of parts, which will be partly illustrated a a preferred embodiment in the accompanying drawings and described in the specificatiom-althouyh the invention is protected for all desirable changes and uses within the scope of the invention as claimed.

although it is desired to be understood that any other preferred form of receptacle or body may be employedy A cover 11 is-providedfor the receptacle and is reincrably held on the same through the medium of a plurality of fasteners 12, located at spaced points and preferably three (3) in number. Each of thesefasteners comprises a strip of metal 13 secured toe-cover radially and having its free end coiled to form.an eye 14:,Wl110l1 pivotally carries a de ending link 15.-,-;A strip-l6 is secured vertically to the adjacent portion of the receptacle and has its upper: end bent outwardly at right angles and terminating in spaced eyes 17 between whichla locking lever- 18 is pivotally XDOlIIItBdyfiOdLlliLt when the cover is in PO51- tion the levers mayabe extended through the links so that the latter will engage beneath the angular portions of the strips 16 inwardly ofv the eyes thereof and when the levers are moved downwardly, the links will be held from disengagement and the cover thereby secured on the 'rece tacle Mounted onthc bottonroi the receptacle at the inside are diametrically opposite pairs of sockets 18, the same havin flanged portions attached to the bottom w ile the openings ofthe'socket taper toward their lower onus. A plurality of dashcrs 19 are mount ed within the receptacle and each consists ofna iverticglshdaft 20 rpvidcd with vertica y space an ,0 osite extendim a ertured bladcs'or paddles 21; four (4) 3f s iich dashers being rovided and having their blades arrange in stag ered relation with respect to the adjacent ashers, The lower extremities of the shafts are tapered as shown at 22 to engage the openings of the sockets to freely rotate therein, while spaced above said tapered. extremities, said shafts are provided with enlargements 23 producing shoulders which abut sleeves 2% formed at thecxtremitiosof a plurality of arms 25 forming a cross brace and which has a central hub 28. This cross brace thus supports M the shafts in spaced relation with the shouldersresting on the sleeves 24 and the top portions of the shafts are rovided with enlargements 27 producing s oulders engaged by similar sleeves formed at the extremities of the arms-10f a similar cross brace 28. The hub portions of these braces are connected-by cred or bolt 29 with nuts or ca s 30 mounted on their extremities whereby tlie will r:

The pinions are retained on the leaner sheiea'through the medium or arcuate braces 35, the same having' oilset aperturedends 86 attached to the r-ingdikc plate 32 and the oover'll and also having interincdiatedependine bearing cups ll-T'rcbatably receiving the hu e-or thepinions eherein while at the same time preventing upward-displacement ofthe shafts: ii hearing bolt 88 is moored centrally thr ugh a cover, being held by 'anu t 39am having an: upwardly flanged bearing plate 2 0 011 wardly of the cover to receive the r lower poieion or flange-of the hub 3:1 of a icel 4a, the top flange of said hub 41 i mg held in a flanged nut 43 so that the hub el' is rotatahlymounted on -the unthreaded poreion of ehebolt 38. The nut 43' mounted on ehe reduced threaded u er ex emity of the bolt fldond is provi ed with opposed openings adepted'to rogister with an opening in said thrcadedportion for receiving a key 44,v thus preventing the nut from jamming against or loosing from the hub of the gear 42. The teeth of the gear 42 are located on the inside of a depending; flange 45 forming ite rim so that said gear will be disposed in mesh with all of the pinions 34 for simultancouely driving said pinions and attach shaftainthe same direction, thus driving the dashers at a high speed of rotation. I

The gear wheel 42 is formed with an upwardly extending pinion 46 which is spaced from the hub and is adapted to berotuted through an intermcahed vcrticalgear 47. This rear 4? is supported between the spaced oiisct portions es of an arched support 49 to the cover and a brace 51 which has its extremities secured to the support .9 beyond its oiiect portion as shown at 52. Both of the oil'sct portions 48 are provided with opposed circular apertures intermediate their ends for receiving the circular extremities 53 of a squared bolt 54: on which the drive axle l? in keg/ed between the client portions-e8 while a hand crank 55 is occurs-d to one cirvruler portion of theequared shaft in rotate are; ect to the support or bearing.

ooverie placed thereon and held by the liestenersf or locking means described. "The upper'extremities of the dasher shafts will enyage through the apertures of the cover an 1 the squared portions thereof will en gage the squared apertures of the pinione 34, whereupon rotation being imparted to the drive gear 47, such motion will he tranemittcd through the pinion 46 to the gear wheel 42 and by driving the pinions 3e rapidly rotate the dashers. l3 reason of the great speed of rotation w iich can be imparted to the-dashers, the number of the ac dashers-andalso the constructions end arrangement of'the-bladee or paddles thereof, theglobulce of cream will be thoroughly agitated and broken up and the churning operation expcditml.
