CHURN.

SPECIFICATION forming part of Letters Patent N 0. 499,234, dated June 13, 1893.

Application filed May 31,1892. Serial No. 435,107. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW M. LANCE, a citizen of the United States, residing at Bellowsville, in the county of Beaver and State of Pennsylvania,have invented certain new and useful Improvements in Ohurns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The special object of the invention is to make a churn which may be conveniently operated, without gearing, hand-crank shafts, or other operative mechanism, but simply by combining hand power with springs as hereinafter described. 7

Figure 1 of the drawings is a side-elevation, Fig. 2 a vertical horizontal section, and Fig. 3 a vertical cross-section.

In the drawings, A represents an oblong churn body with any preferred detachable cover and two side-flanges a a on the upper face, opposite to each other. These flanges are provided with vertical and horizontal holes communicating with each other, to receive the angled ends I) b of the yoke B, which is journaled in the base of the frame 0. This enables the churn body to be vibrated by the handleb' back and forth, for the purpose of agitating the cream.

E are spiral springs which connect the bottom of the churn body at each end with the crossbars F F.

To the sides and at the middle of the churnbody are attached the plates 0. a which project down nearly to the blocks D and are connected to the upper part of the posts H H by the end-pivoted rods G which serve to regulate both the longitudinal and lateral movements of the body. The cream having been poured into the churn body at a proper temperature, the operator pushes or pulls the churn, by means of the handle 5', down at one end and lets it go; the springs then cause it to vibrate in diminishing arcs until another impulse is given with the hand. This mode of operation is continued for a few minutes when the butter will come. and require to be treated in the usual manner. The rods G support the whole weight of the churn until it is thrown on its ends when the plates, which do not turn on the blocks, meet the ends of the blocks so as to stop the downward motion, causing the cream to receive a sudden jar. At this time, the weight is on the blocks, but as'soon as the churn is started back by the springs, the weight is assumed by the rods. Thus it will be'seen that the springs keep the churn in constant motion, necessitating very little effort on the part of the operator.

Having thus described all that is necessary to a full understanding of my invention, What I claim as new, and desire to protect by Letters Patent, is

A churn consisting of the body A having flanges a a, and plates a a, a yoke B attached at the upper ends to said flanges and journaled at bottom in the supporting frame, the V blocks D D and spiral springs E E on a crossbar F and the rods G connecting the plates at a with the upper ends of the posts H H, all arranged substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
