Application filed September 25, 1906. Serial No. 336,194.

To aZZ whom it may concern.-

Be it known that I, MAX F. STADTMULLER, a citizen of the United States, residing at Pomeroy, in the county of Calhoun and State of Iowa, have invented certain new and useful Improvements in a Combined Churn and Butter-lNorker, of which the following is a specification.

The present invention appertains to mechanism for churning cream in the formation of butter and working the same after the addition of salt thereto, both operations being performed by the same mechanism.

The invention contemplates an apparatus embodying arotary drum and a rotary dasher and mechanism for imparting movement thereto, whereby both the drum and dasher may rotate together, or the drum have movement imparted thereto independently of the dasher, or both be rotated simultaneously in opposite directions and at difi'erent rates of s eed.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, it which Figure 1 is a perspective view of a combined churn and butter-worker embodying the invention. Fig. 2 is a vertical central longitudinal section of the churn and cooperating parts. Fig. 3 is a transverse section on the line 2!; a; of Fig. 2. Fig. 4 is a detail view of the operating mechanism, showing the gearing moved to cause both the churn and dasher to rotate in opposite directions. Fig. 5 is a view of the parts shown in Fig. 4, illustrating the position of the movable gear elements when the churn and dasher are locked so as to rotate together. Fig. 6 is a detail perspective view of an end portion of a roller and a supporting-arm therefor.

Corresponding and likeparts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The framework comprises longitudinal bars 1 and A-standards 2, the legs of said standards being provided near their lower ends with lateral projections 3, which are apertured to receive the fastenings employed for connecting the longitudinal bars 1 to the standards. The lower ends of the legs are bent outwardly to provide feet and are apertured to receive fastenings should it become necessary to secure the framework to a floor or other support. The upper ends of the standards are depressed to receive trunnions at opposite ends of the churn-body, capplates 4 being folded or otherwise secured to the upper ends of the standards to retain the trunnions in place thereon, said cap-plates being upwardly deflected intermediate their ends to fit about the upper portion of the trunnions. An arch-bar 5 is secured at its ends to projecting end portions of the longitudinal bars 1 and is provided intermediate of its ends with a bearing 6 in which the outer end of the drive-shaft 7 obtains a bearing, the inner end portion of said drive-shaft being supported in a like bearing 8, applied to the cross-piece of the proximal A-standard2. Motion is imparted to the drive-shaft 7 from any suitable source of power in any wellknown way, and for this purpose a band-pull 9 is fast to said drive-shaft and is adapted to have power applied thereto by means of a drive-belt (not shown) in the accustomed way. The inner end ofthe drive-shaft is provided with a pinion 10, which is in mesh with the teeth of a cog-ring 11, secured to the end of the churn body or drum adjacent to the operating mechanism.

The churn body or drum 12 may be of any construction and is preferably composed of heads and staves arranged about said heads and held in place by hoops or bands. Access is had to the interior of the churn. body or drum through an opening in a side thereof which is closed by means of a door 13. The

inner wall of the drum is provided with longitudinal strips 14 and angular strips 15. The longitudinal strips 14 terminate a short distance from the inner sides of the heads and 'i are spaced apart an equal distance and have a parallel relation with one another and with the axis of the drum. The strips 15 are arranged in the spaces formed between the heads and the ends of the longitudinal strips 14 and are oppositely inclined, the purpose being to work the butter from the ends of the,

drum inward toward the center, thereby keeping the same within range of action of the rotary churn-dasher.

Trunnions 1-6 and:

2 1, the same obtaining a bearing in an iron 17 are secured to the ends of the drum or 1 churn body and are mounted in the bearings provided at the upper ends of the standards 2. The trunnion 16 is provided at its outer end with a packing-gland 18 to make a tight joint between it and the shaft 1.9 of the retary churn, said shaft passing entirely through the drum and having its inner end mounted in an opening formed in the trunnion 17. The opening in the trunnion 17 receiving the inner end of the shaft 19 is closed at its outer endthat is, it does not extend entirely through the trunnion 17. Hence there is no i provision for waste at this point and no necessity for supplying a packing-gland, as is the case with the trunnion 16.

The dasher is of the rotary type and comprises arms 20, cross-bars 21., and rollers 22, the latter being journaled between the extremities of the arms 20 and longitudinally fluted, so as to effectively work the butter after the churning operation has been completed. A central support 23 connects the arms 20 at a central point and is formed with a longitudinal opening through which the shaft 19 passes, thereby preventing contact of the cream or butter with said shaft. Each roller 22 is provided at its end with a journal 25, which is secured to the end of an arm 20. The irons 25 are let into the arms 20, so to be protected and prevent contact of the cream or butter th erewith. The dasher is of a length and width corresponding approximately to the interior length. and diameter of the churn body and drum, so as to thoroughly break up the butter particles and insure the gathering and the working of the butter.

.lhe shaft 19 of the rotary dasher pro roots beyond the outer end of the trunnion 16 and receives a gear-wheel 26, which is splined thereon, but free to move toward and from the trunnion 16. Clutch-teeth 27 are pro vided on the inner side of the gear-wheel 26 and are adapted to cooperate with corresponding clutch-teeth 28 at the outer end of the trunnion 1.6, thereby providing for causing interlocking of the dasher and churn-body, whereby the two may rotate together, as when churning. A pinion 29 is loose upon the drive-shaft 7 and is at all times in mesh with the gear-wheel 26 and moves therewith A half-clutch 30 is provided upon the outer side of the pinion 29 and is adapted to cooperate with a half-clutch 31 fast to the driveshaft 7. When the pinion 29 is moved upward to cause its half-clutch 30 to engage with the halfcluteh 31, the pinion and driveshaft 7 rotate together, and by reason of said pinion being in mesh with the gear-wheel 26 and the latter in turn splined to the sh aft 19 of the dasher thelatter will havemotion imparted thereto simultaneously with the churnbody, but in a reverse direction and at a d ifferent rate of speed, because of the difference in the diameters of the respective cooperating gear elements 26 29 and 10 and 11. A shipper-lever 32 is pivoted. at 33 to a longitudinal bar of the framework and has positive connec tion with the gear-wheel 26 and pinion 29 to cause both to move together upon their respective shafts 7 and 19.

The cream to be churned is introduced into the drum of churn-body through the opening closed by the door 13, and the shipper-lever 32 is moved to bring the clutch elements 27 and 28 into engagement and the clutch elements 30 and 31 out of engagement, thereby causing the churn and dasher to rotate together. After the cream has been churned and the butter collected and it is desired to work the butter either to incorporate salt therein or to eliminate milk and water or for any desired purpose the shipper-lever is moved to throw the gear-wheel 26 out of clutched engagement with the churn-body and to throw the clutch members 30 and 31 into engagement, and upon continued rotation of the shaft 7 the churn body and dasher are rotated in opposite directions and at different speeds. After the butter has been worked sufficiently it is removed through the opening closed by the door 13, as will be readily understood.

Having thus described the invention, what is claimed as new is 1. In combination, a churn-body, a rotary dasher, a drive-shaft, gearing between the drive-shaft and churn-body, a gear element splined upon an extension of the dashershaft, a clutch between said element and churn-body, a second gear element in mesh with the first-mentioned gear element and splined to the drive-shaft, a clutch between the'second gear element and the drive-shaft, and means for simultaneously moving the said gear elements either to lock the dasher to the churn-body or to impart opposite rotary movement to said dasher and churn body.

2. In a combined churn and butter worker, the combination of a rotary churnbody, a rotary dasher mounted in the churnbody and having an end portion of its'shaft extended, a drive-shaft in constant gear with the churn-body, a gear-wheel splined. to the projecting end. of the dasher-shaft, a clutch between said gearwheel and the churn-body,
