Specification of Letters I Patent Patented Dec. 29, 1908.

Application filed September 14-, 1908. Serial No. 462,824.

To all whom it may concern: Y

. Be it known thatI, DANIEL A. SPRAGUE of Poland, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in a Combined Churn and Butter-Worker; and I'do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The object of my present invention is to provide a combined churn and butter worker, which is simple in construction, efiicient in operation, easily operated, easily cleaned and reasonable in cost of construction.

Figure 1 shows an end view of my present machine, with a section broken away: to re.-.

duce the size of the figure. Fig. 2 is" a longitudinal sectional view of the same. Fig. 3 is a cross sectional view through the body.

Fig. 4 shows the opposite end from that shown in Fig. 1.

Referring to the reference figures in a more I particular'description, 10 indicates the body of the churn, which is of cylindrical form, having heads in each end and all together forming a receptacle mounted on journals 11 and 40 in the standards ofthe frame 13 for rotation, The body is provided with an opening through which access may be had to I the interior for the purpose of introducing the cream, salting, inspecting and removing the butter and washing and cleaning the interior of the rece tacle with its accessories. The 0 ening is a apted to be closed by a remova le cover 14. For rotating the body on its horizontal axis, the journal 11 is extended and provided with a crank 15. For rotating the body more slowly and with greater power a gear pinion 8 is provided with a s ort shaft mounted in a'bearing on the standard of the frame and meshing with a gear wheel 9 provided on the body end and preferably ma e integral with the journal ase plate. The crank 15 may be transferred from the journal 11 to the shaft carrying the pinion 8.-

Extending longitudinally through the body on the axle e and in the line of the journals 11 and 40 is a shaft 16 incased and provided with a set of substantiall radial projecting fingers 18, all toget er constituting the worker 17. The fingers 18 are member 30".

well spaced and relatively narrow as com-' pared with the space, and preferably disposed as to their secured ends on both'sides of the shaft 16, whereby they are somewhat offset with reference to one another, but all projecting in the same general radial direotion from the axis on one side of the axis of the churn body. The shaft 16' with its fingers constituting the-worker is rotatable in dependently of the body of the churn, and at one end has a bearing in and extends through the journal 40, and at the other end has a bearing at the base of the journal 11, but preferably does not extend through.

For controlling the worker there is provided a hand wheel 30 mounted on the externally extended end of the worker shaft 16, preferably by being provided with a square ole receiving a square section of theworker shaft, whereby the hand wheel is held front rotation with referenceto the shaft; but the arrangement is such that the hand wheel may be moved laterally along the shaft a limited distance. The hand wheel 30 is provided at one end with clutch teeth or clutch member 30*, and at the other end with another clutch The clutch member 30 is adapted, when the hand wheel is shifted in the roper direction, to engage with clutch mem er 40- on the end of the journal 40,

thereby securing the worker to the body for rotation therewith. I

.4 At the outer end of the shaft 16 there is rozided a stationary or fixed clutch member 41 supported and held by an arm 42 from the frame. When the hand wheel is shifted in the proper direction, the clutch member 30*- of the wheel may be engaged with the stationary clutch member 41, whereby the worker is held against rotation while the body is adapted to be freely rotated. The arrangement of the hand wheel and clutch members is also such that there is an intermediate position for the hand wheel when both clutcheswill be out of engagement, at which time the worker is under independent manual control by the hand wheel. The hand wheel has a set screw 37 by means of which it may be secured in any of its several positions of ad'ustment along the shaft 16.

Within the ody the churn is prozided with a set of inwardly projecting fin are 25, which are rigidl secured m the walof the body and exten I nearly to the axial line in a radial direction, if desired, but preferably with a somewhat forward 1 inclination as shown in the drawings. The set of body} posed with reference to those of the worker,

so as to pass through the middle of the spaces between the worker fingers when they are relatively rotated with liberal clearance space between when passing. I

The clutch members and 10 will preferably be soarranged that they can be engaged only in one position, and, further, the arrangement will preferably be such that this engagement can only be made when the worker fingers are interposed or interpositioned with the body fingers.

For churning, the combined body and worker fingers constitute a single dasher. In churnin the body should not be filled more than ha full of cream. In the revolution the dasher strikes down on the surface of the cream, rakes through the body of the cream, and then passes above the surface, afiording ample time for the cream to become settled before repeating the operation. The clearance between the fingers, even when interposed,

allows the cream to pass through quite freely. With what might perhaps be considered too rapid a rotation of the churn in churning, the cream might be carried up or forward by the dasher, in which case it would be poured over the shaft and the fall would be effective in churning.

The churning is preferably stopped when the butter has come in granular form (as to be noted through a glass covered hole),

' and the butter milk drawn off and the butter ber 41.

washed and salted. While drawing off the butter milk and salting the butter, the hook 21 may be engaged with the eye 22 to secure the body against rotation. For the purpose of workin the butter, the position of the hand whee 30 will be shifted so as to engage the clutch member 30 with the clutch mem- These clutch members are arranged preferably to be ca able of engagement only in one position, an that preferably with'the worker fingers 18 on a downwardly inclined angle, as shown in Fig. 3 of the drawings. The worker being set, that is to say, secured in a stationary position and the body of the churn rotate in the direction of the arrow shown in Fig. 3, preferably by means of the crank 15 apbplied to the inion 8, the butter is gathered etween the fiiigers 25 and 18 and a portion forced through the fingers 18, while a portion escapes backwardly through the r fingers 25, effecting a squeezing and break 1 B 5 ing or cutting operation, constituting effective sosnea working. The portion of the butter which passes through t e fingers 18 is carried ahead of the fingers 25 until it is dumped over the shaft 16 and it, together with the butter that has passed backwardly through the finers 25, is gathered and massed and again forced through the fingers 18 with the next revolution.- A few revolutions of. the churn body when thus 0 erating will produce a sufficient working. en the Workin has been completed, the worker will prefers ly be returned to its former position with the fingers 18 and 25 interposed and secured in that position. The churn now being revolved the more or less broken body of butter will be athered ahead of the combined fingers and umped over the shaft. .A few revolutions in this operation will mass and packthe but- 1 ter in a single body and in a desirable condition to 'be removed from the churn.

The offset position of the fingers 18 on the worker, or the offset osition of the fingers 25 on the body if emp oyed, enable the churn to work butter with the a plication of somewhat less power than t ough each set of fingers were arranged in a single plane, for obvious reasons. The offset position of the fingers when combined to constitute a dasher also forms a dasher which affords larger pas-- sages for the cream between the fingers, which in some views of the matter is an advantage.

Churns require very careful cleaning, for

which purpose ready access is desirable to all interior parts. In washing and cleaning this combined churn and butter worker, the hand wheel 30 will be adjusted to its intermediate position, placing the worker readily under the control of the operator and allowing it to be positioned to afford access to all of its arts, and to remove it from any position w iich would prevent ready access to the body fingers and all parts of the interior. of the body.

It is evident that other modifications and changes in and from the construction herein described may be made without departing from the invention hereinafter pointed out and intended to be claimed in the claims.
