. UNITED STATES PATENT OFFIC JOHN ASHBURY LAUGHERY, OF DENISON, MISSOURI.

CHURN.

SPECIFICATION forming part of Letters Patent No. 357,013, dated February 1, 1857.

Application filed duly 17, 1886.

Serial in. 203,260. (No model).

To all whom it may concern:

Be it known that I, J OHN AsHBURY LAUGH- ERY, a citizen of the United States, and a resident of Denison, in the county of Barton and State of Missouri, have invented certain new and useful Improvements in Ghurns; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference-being had to theaccompanying drawings, which form a part of this specification,

and in which churns in which a boxlor churn-body is sus-- pended in a swinging frame, and in which a stationary dasher is suspended within the box or body; and it consists in'the improved con struction and combination of parts of such a churn, as hereinafter more fully described-and claimed. 7

In the accompanying drawings, the letter A indicates a rectangular upright frame supported upon a suitable base, B, and the side pieces of this frame are provided with horizontal cross-pieces O (J, from the ends of which are suspended a pair of pivoted arms, D D,while a pair of handles, E E, connected at their upper ends by a handle-bar, F, are pivoted at or near their middles upon the other ends of the crosspieces, the portions of the handles'below their pivotal points being of the same length as the pivoted arms. A swinging platform, G, is

supported from these arms and handles, having the lower ends of the same pivoted to .its sides near the corners, and the box or body H of the churn rests upon this platform.

The box has outwardly-inclined end pieces, and the bottom of the box is provided with transverse cleatsI I at its ends, which cleats bear against the ends of the platform, retain-' ing the box upon the platform, and the top of the box is covered by a cover, J. This cover is formed with two frame -pieces, K K, or braces, which support a long box, L, secured over a longitudinal slot in the cover, and the 5 I upper open end of this long box is Provided wit-h grooved ways M M, or guides, in which a plate, N, slides. This plate or slideis formed with a perforation, O, at its middle, and the staff 1? of the dasher Q fits in this aperture or perforation, the upper end of the staff being secured by means ofa pivoted latch-bar, R, in a recess, S, in one side of the top cross piece of the frame.

The dasher is perforated, and is of nearly the same dimensions as the cross-section of the interior of the box, nearlyfilling the space between the sides and top and bottom.

The slide in the cover is longer than the box and slot, so that the slide may be slid to both sides, bringing the aperture in it to both ends of the slot and box and still allowing the slot and box to be covered.

When the box has been filled with cream, it is placed upon the swinging platform, and the cover is placed upon the box, with the dasherstaff projecting through the aperture of the slide, which is in position in its ways. The upper end of the dasher-staff is thereupon secured by its latch, and the swinging platform and the box may now be reciprocated, causing the cream containedwithin the box to be forced through the perforations of the dasher, and thus breaking the butter-globules, the passage through the perforations, together with the swinging motion of the body, which causes the cream to swash or wave in the box, causing a rapid breaking of the globules and consequent formation of the butter.

The cover is preferably provided with a suit- 0 able aperture, T, through which a thermometer may be inserted, and through which the condition of the cream and its temperature may be observed. The inclined ends of the boxallow/the swinging box and platform to be so reciprocated that the dasher will reach to both ends of the box, and the slide being sufficiently long will cover the slot and open side of the box upon the cover when the box and plat form are at both extremities of their stroke.

The churn is very simple of construction,and may consequently be made of very strong material, causing it to be durable and not liable to get out of order, and as all parts of the churn which come in contact with the cream may be made of wood there is no danger of tainting the cream or the butter with any metallic tastes.

Having thus described myinvention, I claim and desire to secure by Letters Patent ofthe United States In a churn, the combination of a rectangular upright frame having cross-bars near the upper ends of the side pieces, a pair of arms pivoted at the ends of the cross-bars, a pair of handles fulcrumed upon the ends of the crosspieces and connected at the upper ends by a handle bar, a platform suspended from the lower ends of the arms and the handles, a churn-box upon the platform. a cover upon the box having a longitudinal slot provided with a box at its edges having grooved ways JOHN ASHBURY LAUGHERY.
