To all whom-"it may concern: Be it' known that I, JOHN ,R. G1LDA,-a citizen of the United States, residing at the city of St. Louis, State ofcMissouri, have 1, lustrating J invented certain new and, useful Improve-. ments in Churn's, of which the following 1s a specification, reference being had to the accompanying drawings,- forming a part hereof, in which Figure l'is a front elevational view, partly in vertical section, of a churn constructed in accordance with and embodying my-'-'-'ii'1 vention; Fig. '2 is a side elevational view,

artly in section, of the same; Fig. 3 is a retail sectional view on the line 3-3, Fig. particularlythe means for varying'or a ustin the vertical travel of the cross-head and the stroke of the dasher carried by the cross-headyahd Fig. 4 is a.

detail sectional view on-the line H, Fig. 1, illustrating particularly the means for draining surplus lubricant away from the top of the liquid-receptacle.

This invention relates to certain new and useful im rovements in churns, and more particular y to that class of churns having reciprocatory dashers, such as shown and vide a dasher-operating mechanism for described in United States Letters Patent No. 989,776, dated April 18, 1911..

The objects of my invention are topro- I churns of the kind stated, in which not only is the dasher adjustable with relation to its operating mechanism to accommodate liquidreceptacles of various or different depths, but in which also. the stroke of the dasher is adapted to be adjusted ,or varied-shortened or lengthenedto accommodate in a particular liquid-receptacle different quantities of the llquid (usually milk or cream) to he churned; to provide a dasher'operating mechanism for churns of the kind stated which may be. used in connection with. and which may be readily, easily, and quickly arranged and held in, or removed from, operative position on, liquid-receptacles of various sizes; to provide a dasher operating mechanism for churns of the kind stated in which certain parts (more fully hereinafter described) of the 'das'her-operating mechanism may be maintained in a thoroughly lubricated condition without any liability of such lubricant entering the liquid receptacle to the consequent damage or in- .juryof its contents; to provide a churn of the kind stated in which the dasher-operatchurning, the mine will bedrained back 5 This base or'supportin -member 7 is i atented Apr. 9,1912.

ing mechanism is spaced away from the top. of, the liquid-receptacle and in .which the lid for the liquid-receptacle maybe raised and the contents ofsaid receptacle inspected so .withoutmecessitating or requiring the removal of the flasher-operatingmechanism; 1 and to improvegenerallyupon churns of the kind stated. With these objects in view, my invention resides in the novel construction, arrange-I" ment, and combination of the several'part s" of my dasher-opera ting-mechanism and in: the novel arran ement and combination of the same with a iquid-rece tacle, all as will herein be described and a terward pointed out in the claims. ,In the drawings, wherein "like refere 'ce numerals refe'rto like parts throughout several'views, 1 indicates a" receptacle ionthe liquid such as milk-or. cream, cube churned, this receptacle being of an, it able material and preferably'c lin'drical in; shape. Receptacle 1 is -prefera Iyprovided adjacent its upper inner gedge withI an an nular shoulder. or oif-setiportio'n 2 adapted to provide a hearing or support fora lid of closure 3 for the open end of receptacle 1" adapted to prevent the contents ofthe ceptacle from splashing out during the o eration of burning. Cover 3 isv rovided with a suitable manipulat-ing-kno tandalsowith acentral aperture through which a dasher-rod 5 having a suitabledasher 6 I secured on its lower end is adapted tol'pass 9'0 and in which said dasher-rod 5 is adapted to move on the reciprocation thereof, as will be well understood. As shown particularly in Fig. 1, cover 3 is preferably formed or made slightly concaved on its upperor top surface around said central 9. .erture, so that,

should any of the contents 0 said rece tacle 1 pass or be splashed up through sai central apertureduring the act or operation'of into said receptacle. '7 indicates what might be called the base or supporting-member upon which the dasher-operating mechanism is mounted. provided,-as shown particu arly in Fig. 1, with a plurality of depending supporting-legs 8, of which there are preferably three. ar-

ranged equidi stantlyapara each of said legs being provided adjacent its lower-end with, a threaded opening adapted to receive an adjusting-screw 9 having pivotally mounted on its inner end a clamping-member 10 adapted to operatively engage the upper rim of receptacle 1 and thus maintain said base or supporting member 7 in operative position above and spaced away from said receptacle. As shown-clearly in Figs- 1 and 2, each of said clamping members 10 preferablycomprises Fa hook-shaped portion 11 adapted to extend overand engage the rim heavy lower portion12 adapted to act as counter-balance to maintain the clampingat a point above the 'center of weight thereof with a lurality of prongs or-projections 13 adaptec to be bent over so as to embrace the ball-shaped end on the screw 9. By this construction, a strong and simple lswiveled connection is obtained between. the, adjust- -mg -screws and their clamping-members 10.

Preferably the diametrical width, as it might be called, of base7 is such that the same with its depending legs 8 may accommodate, or be arranged in operative position on, liquid-receptacles of various diameters, whereby the said supporting base 7 and the dasher-operati'ng mechanism mounted thereon may be used in connectionwith liquid-receptacles of. anions sizes,itbeing only necessary to adjust the said ad justing-screwst) with their clamping-moor bers 10 to fit the particular liquid-receptacle upon which itis desired to o eratively arrange said base 7 and the das er-operating mechanism mounted thereon. It will also be noted that, after said base 7 and the dasher-operating mechanism mounted thereon have been arranged upon', and the said adjusting-screws .9 and their clamping members it) have been adjusted to fit, any certain sized or particular liquid-receptacle, two of Stllt. adj ustin' -screws are preferabl' releasably locked or maintained in such a justed positions by any suitable means, preferably such as the jam-nuts 14 shown particularl y in Figs. 1 and 2, the other or remaining adjusting-screw being unlocked, as it might be said, in said adjusted position. Due to this construction, it will be further noted that, should it afterward be desired to remove or dismount said base 7 and the dasher-operating mechanism thereon. from operative. position on said receptacle, itis merely necessary to unscrew said unlocked adjustinq-screw- 9, so as to loosen or disengage its clamping-member 10-from said receptacle 1, when said bu e and the dasheroperating mechanism-then n may be readily dismounted, and that, when it is again desired to operativi-ly mount the base 7 with its dasber-opcrating mechanism upon said of the liquid-receptacle and'a comparatively clamp its said clamping-member receptacle, it is merely necessary, after mounting said base Twith its operating mechanism on the receptacle and arranging said locked clamping-members 10 in proper position on the rim of said receptzurie, to 7 manipulate and tighten said loosened or unlocked adjustingscrew, so as to again also 10 upon said rim. It will further be noted that in mymew construction the said supportinglegs 8. are preferably elongated, as 1t might be said, or of such a length that, when said base 7 with its dasher-operating mechanism is arranged in operative position on a receptacle 1, the same will be spaced above the top of said receptacle, whereby a space is provided between said base and the top of said receptacle in which the cover 8 may be vertically raised, should it be desired to inspect the contents of the receptacle, without requiring or. negessitating the removal "from said receptacle of said base "T and the dasher-operat-ing mechanism mounted thereon. The dash'er-operating mechanism com- 9 prises a suitable standard 15 mounted upon said base 7and having suitably journaled therein a short -hoiizontallysdisposcd shaft\ 16, as shown particularly in Fig. 2. Mounted upon and siaitabl y secured to one end, which we will callthe forward end, of the shaft 16 is a crank wheel 17, and mounted upon and suitably secured to the rearward end of said shaft is a pinion 18, said pinion meshmg with-an internal gear wheel ltljournaled T10C upon-it stub shaft 20 mounted in and projecting, rcarwardly from said standardllo at a point above said shaft 16, as shown clearly in Fig. 2. An operating handle 21 is, as shown clearly in Fig. provided on said gear wheel .19, and a suitable hand a 35 is prefe ably arranged on the top of said standard 15, whereby the dasher-operating-' mechanism and the liquid-receptacle 1 upon which the same is mounted may be firmlyl held during the act of churning, as will be clearly understood. The crank wheel 17 is preferably provided with a somewhat heavy rim, it being adapted to act as a fly wheel when the d."sher-opointing-mechanism is being operated, and, isalso provided with a radially-disposed slot 22. in which slot is adjustably -mounted a block 23 having a clamping-screw 23 and carrying, a roller 2-1: adapted to engage and roll in a horizontallydisposed groove 25 formed on the rearward face of a cross-head 26, 'Ihis'cross-head 26 is, as shown particularly in Fig. 1, provided with a plurality of bearing-lugs 28, which are'adaptcd to slidingly fit on or engage with a pair of verticaEly-disposed guide: rods 29 having their lower ends removably seated in preferably cup-shaped bearin 30 formed on said base or supporting-mom er 7 and their upper ends removably supported 0 in arms 31 projecting forwardly from said standard adjacent the upper end thereof. Short screws 32 are preferably threaded into said arms-31, as shown clearly in Fig. 1, above the upper ends of said rods 29, so as to removably holdsaid rods firmly in position. Said cross-head 26 is centrally provided, as also shown in ig. 1, w1th a perforated boss'27 adapted to receive said dasherrod 5 and in which said dasher-rod' to the dasher-rod 5 and its dasher 6 connected to or carried by said cross-head, as

.1 will be clearly understood.

- dasher shall preferably be flush with, or but .slightly above, the surface of the liquid to Not only is it desirable ii -churns of the kind stated that the dasher be adjustable relatively to its operating mechanism, so that the dasher-operating mechanism may be used with or accommodate receptacles .of various or different depths, such adjustment being particularly provided for by thesaid set-screw 27, .as will be seen, but Ihave found that it is also desirable in churns of the kind stated that the stroke'of the dasherrod be such that, on the end of the up-stroke of the dasher-rod, the lower face of-the be churned in the receptacle 1, so that there shall be no lost motion between the dasher and the contents of said receptacle and so that the dasher on the down-stroke willenter such contents without much splashing,

and,'for this reason that the'stroke' of the dasher be also adjustable relatively to the.

the end of the up-stroke of the dasher-rod,

be flush with, or but slightly above, the surface of said contents. Now in my construction it will be seen that by adjusting said block 23 radially or inwardl or outwardly from thecenter of said crank wheel 17, the

- stroke of the dasher-rod 5 will be shortened or lengthened, for, as will be clear, the nearer said block 23 may be to the center of said crank wheel 17 the less the travel of said roller 24 in said gr ove 25, and likewisethe less the reeiprocatory travel or stroke of said cross-head and of said dasherrod 5 and dasher A carried thereby. It will further be seen that this adjustment maybe easily and quickly had by merely unscrewing said clamping-screw 23K and moving said block 23 inwardly or outwardly in sai slot 22, as may be desired, the clampingscrew 23 being afterward again tightened. By this adjustment, not only will it be seen, as stated, that the stroke of the dasher may be so varied or adjustedlengtliened 01' shortenedto accommodate varying quany tities of liquid in said receptacle, so that, on the end of the up-stroke of the dasherrod 5, the lower face of dasher 6 may be flush with, or slightly above, the'surface'of the liquid in said receptacle 1, but it will further'be seen that, since the. dasher-rod 5 makes one complete strokeup and downfor each revolution of said crank wheel 17 the shorter the stroke of said dasher-rod, the less power will be required to reciprocate or operate the same and the less the relative reciprocatory speed of the dasherrod 5 and its carried dasher 6. In'order that said cross-head 26 carrying said dasherfore such lubricant has frequently'escaped ihto the receptacle :1, to the consequent,-

damage or injury of .its contents. In my construction, however, to obviate this, the said rods '29 being mounted at their lower ends, as described, in the cup-shaped cavities or bearings 30, these cavities will re deive and collect any surplus or excess lubricant from said rods 29 and thus prevent the same dripping or running down therefrom into said receptacle 1; and, as a: further preeaution,'I prefer to provide on the upper surface of saidsupporting-member or base 7 adjacent each -of said cup-shapedbearings .or cavities 30 a channel-shaped groove 33 inclining downwardly and extending outwardly away from the center of said receptacle, each of said cup-shaped bearings 30 being preferably provided in its upper edge, as shown particularly in Fig. 4, with 'a small notch 34 arranged directly above or in alinement with itssaid groove33, so that, should said bearings overflow, the surplus lubricant will be directed into said grooves 33 and thence downwardly and outwardly away from said receptacle 1. In my construction, it will further be notedthatsaid guide-rods 29, being, as itmight be said, loosely mounted on said standard and base, may bereadily removed and replaced whenever necessary or desired.

From the foregoing, it will be seen that my riewchurn is comparatively simple, may

be easily constructed, and fulfils in every respect the objectshereinbefore stated. I am aware that minor changes in thev arrangement, construction, and combination of the several parts of y new dashepopl crating mechanism and in the arran ement and combination of the same with a i uidreceptacle may be made and substitute for,
