BARREL-CHURN.

PECIETCATION forming part of Letters Patent No. 344,503, dated June 29, 1886.

Application filed Xovcinber 30, 1885. Serial No. 155L349. (N0 model.)

To all whom it may concern.-

Be it known that I, JULIUS SMITH, acitizen of the United States, residing at Rock Falls, in the county of \Vhiteside and State of Illinois, haveinvented certain new and useful Improve ments in Barrel-Oluu'ns; 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Hy invention has reference to barrel-churns, and pertains more especially to certain novel mechanism for supporting the churn and rig idly locking the lid.

1n barrel-churns in which, as in mine, the process of churning is carried on by rotating the entire churn,and thereby dashing the cream from one end to the other of the barrel, itis of the utmost importance that every portion of thejunction between the lid and body of the churn be made perfectly tight, otherwise the agitation of the cream, as well as its centrifugal force, will force portions of the cream between the lid and body of the churn, causing some loss of the contents, but more particularly soiling the churn and floor.

In such churns as heretofore constructed the pressure of the lid upon the body ofthe churn has been applied at intervals around the periphery ofthelid, and it has been substantially impracticable to make such pressure uniform around the entire lid, and an excess of pressure at one point would have the effect of tilting the lid at the opposite side; also, the intervals between the points of pressure would receive pressure from the side only, and of course in a less degree. This objectionl have overcome by applying the pressure primarily to the center of the lid, and thence equally throughout the entire edge thereof; again, instead of,as heretofore,clamping but one end of the churn against the lid, the pressure is inward from both extremities of the churn, and thus both the entire lid and the entire body of the churn are included within the compress iug mechanism.

In the drawings, Figure 1 exhibits a front elevation, with the churn in section, of a ma chine embodying my invention. Fig. 2 is a partial cross-section at one side of the churn.

A is the body of the churn, made in the usual mode,and having the usual cork annulusin its upper edge.

3 is the lid, having a convex upper surface and an annular downwardly-extending flange toimpinge upon such cork annulus. As neither the latter nor such flange are any part of my invention, nor claimed by me, I do not deem it necessary to show or further describe such features.

C O arethe supportirig-standards ofthejack, in which the churnframe is suspended, such standards being suitably connected at their lower ends by the cross-brace D and seated in horizontal plates E E.

F is the bottom cross-plate, upon which the churn rests. Rods G and G, having heads a on their lower ends, are passed upward through the plate F a short distance above the churn A. The upper end of the rod G is threaded and provided with nuts I) and I). On the upper end of the rod G is cccentrically pivoted the cam-lever H.

K is a horizontal pressure bar provided with a longitudinal slot, (1, to receive the upper end of the rod G, the nut I) being under such bar and the nut 1) above it, and by means of such nuts the altitude of that end of the bar K can be adj usted as required. A longitudinal slot, 0, is formed on the opposite end oft-he bar K, which latter slot receives the uppcrend of the rod G. By means of the slot d the bar K can he slipped back lengthwise sufficient to allow the rod G to pass outof the slot 6, when the bar K can be turned to one sidc,to permit the removal and replacement of the lid B, when, by slipping the bar K in a contrary direction, its free end can be passed under the lever H. The lever H is so formed and pivoted that its eccentric side or cam will force the adjacent end of the bar K downward by an inward movement of such lever, and as such bar K presses upon the center ofthe lid B the pressure thereby exerted is distributed uniformly around the periphery of such lid.

L is a hoop or band passed loosely around the center of the barrel A and through ears M lVLthe latter being provided with j ournal-bearings g g, respectively, and thus suitably journaled, respectively, at opposite sides of the churn A upon the supporting-standards G (J. The rods G and G pass also through the ears M M and extend laterally into a slight recess, h,'in the outer edge of the baud L, and thus said band is prevented from revolving.

On the outer end of one of the ears M is fitted the crank N, by means of which the churn is rotated.

The advantages of my invention are,that the churn is compressed its entire length, supported at both ends by extraneous mechanism, and that the lid is held in place by a uniformlydistributed pressure.

For the convexity of the lid B, a oleat having a convex upper side can be fastened to the top of such lid under the bar K.

WhatI claim as my invention, and desire to secure by Letters Patent of the United States,is-

1. The combination, with a churn, A, and lid B, ofthe plate F, rods G and G, the bar K, and lever H,substantially as shown,an(l l'ortho purpose described.

2. In combination with the body and lid of a churn, the plate F, rods G and G, bar K, camlever H, band L, and ears M M, substantially as shown, and for the purpose described.

3. Theeombination, with the churn A and lid B, ofthe plate F, rods G and G, the bar K, provided with slots d and e, and the lever H, substantially as sl1own,and for the purpose described.

4. In combination with the churn Aand lid 13, the plate F, rods G and G, the latter provided with nuts I) and b, the bar K, provided with slots 0 and d, and the lever H, such lid B having an upper convex surface, and thus JULIUS SMITH.
