JOHN MCDERN AID, OF ROOKFORD, ILLINOIS.
CLOSURE FOR CHURNS.
SPECFICATION forming part of Letters Patent No. 390,689, dated October 9, 1888.
Application filed July 23, 1888. Serial No.280,766.
To all wwm it may concern.-
Be it known that I, JOHN MCDERNAID, a citizen of the United States, residing at Bockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Closures of Ghurns, of which the following is a specification. This invention relates to an improved means of securing the closures or covers to churns; and it consists of certain new and useful constructions and combinations of parts, which are hereinafter described, and pointed out in the claim.
Referring to the accompanying drawings, which form a part of this specification, Figure l is a plan View of my improved churn-cover secured to the ring-head of a churn. Fig. 2 is a view of a vertical section of the same through the dotted line XX of Fig. l. Fig. 3 is a View of an elevation of the cover and ring-head to which the former is secured. Fig. 4 is an isometric view, in detail, of a portion ol' the churn-cover fastening shown in the foregoing views.
Like letters of reference indicate corresponding'parts throughout the several views.
Aisa ring-head, having the periphery thereof beveled to enter the croze of a churn.
A is an annular iiange projecting from the upper side of the ring-head A, which has a circular opening, A2, therethrough, of the same diameter as the inside of the annular flange A. a
A3 represents ears projecting vertically from the upper side of the ring-head A and having horizontal circular openings A4 in the same to admit parts to be described hereinafter. The ring-head is permanently seated in the chine of a churn, (not shown,) and the ears projecting therefrom are preferably integral therewith.
B is a disk-head, which forms the basis of the churn-cover and has a vertical bolt-hole, B', through the center thereof.
B2 is a metallic casing inclosing the periphery and upper peripheral angle of the diskhead B.
(No model.)
B3 is a transverse strengthening-brace integral with the casing B2 and extending across the center of the disk-head B.
B4 is a vertical stud, also integral with the brace B3, and having a cylindrical passage, B5, extending longitudinally therethrough.
B6 is a ring of cork set into the disk-head B, which engages with the annular flange A and forms a tightjoiut therewith.
C represents bails for securing the cover to the ring-head A, mounted in the ears A3 thereon by inserting the ends of the former through the openings A4 in the latter. These bails may be swung outward or inward, as indicated by the dotted lines X of Fig. l, according as it is desired to open or close the churn.
D is a bolt passed through the openings B B5 in the disk-head and vertical stud, and is secured in position by means of the set-nut D.
E is a fulcrum having a threaded passage, E', extending vertically therethrough to adapt it to engage with the threaded portion of the bolt D to form a vertical adjustable swiveljoint therewith for the former to revolve upon.
F is a lever-cam, consisting of the cam F, pivoted to the swiveled fulcrum E by means of the horizontal pivot F2 and openings F3 in the cam F, and the lever F, integral therewith, foroperating the same. The cam F is divided by a central longitudinal cleft, F5, which admits the fulcruni E,whereto itis pivoted, and embraces the set-nut D, thereby preventing said nut from working loose and serving as a wrench to remove and replace the same, if desired. To take up the slack between the bails and cam or wear of any of the parts composing the fastening mechanism, elevate the lever-cam to a vertical position and revolve it and the fulcrum whereto it is swiveled upon the bolt D, as indicated by the dotted circle X3 in Fig. 1, until the slack or wear is taken up.
When it is desired to remove the cover from the churn, turn the lever-cam F, as indicated by the dotted lines X2 in Fig. 3, whereupon the bails C will be unlocked'. Next swing the bails outward, as indicated by the dotted lines X in Fig. 1. rlhen grasp the cam-handle E, elevating it to a vertical position, and lift the cover from the churn thereby.
I claim# The combination, with a churn having a ring-head provided with swinging bails seated therein, of a cover adapted thereto and provided with a peripheral casing and having a vertical stud, B, mounted thereon, a vertical bolt, D, passed through said cover and stud, ro
a set-nut, D', to secure said bolt in place, the fnlcrnm E, swiveled to said bolt, and a leveream, F, pivoted to said fulcrum, substantially as set forth.
