SPECIFICATION forming part of Letters Patent No. 462,007, dated October 27, 1891.

Application filed June 18,1891. Serial No. 396,102. (No model.)

To all whom, it may concern:

Be it known that I, MATTHEW L. HOYT, a citizen of the United States, residing at Ballston Spa, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Churn Covers, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 represents a perspective view of my improved churn-cover applied to a ch urnbody, a portion ofwhich latteris shown. Fig. 2 is a vertical sectional view of the same on the line -1 1 of Fig. 1, the cover being shown closed and locked and a portion at the lefthand side being shown in side elevation; and Fig. 3 is a vertical sectional view on the line 2 2 of Fig. 2.

The invention isdesigned especially to provide an improved cover for use upon the balanced diamond-shaped revolving churn patented to Hugh F. Murray and myself on the 28th day of May, 1889, and numbered 404,281, of which I am now the sole owner, although it may with equal advantages be used upon other varieties of churns; and it has for its objects the provision of a cover of very simple construction that may be readily locked in place over the opening and securely held during the revolution of the churn-body, and which maybe as readily removed for access to the interior of the churn, as will more fully hereinafter appear.

In the drawings, a designates a portion of the body of a churn, preferably diamondshaped, around the rectangular opening of which is secured a rectangular metallic frame I), this frame being provided all around its inner edge with an upwardlyfextending flange or bead 1). Along the outer edge of one side bar of this frame is formed a vertical flange b,'that abuts against and is screwed to the adjacent edge of the churn-body. Formed on each of the side bars of the frame is a pair of upwardly-extending shouldered lugs b, one lug being located near each corner of the frame.

The cover consists of a rectangular metal frame 0, adapted to fit between the lugs b and provided with a depending flange all around its outer edge. Screwed to the under side of the metallic frame, within the flange,

is a rectangular wooden block or board 0, and

thedepending flange on the frame is a packing-strip c", of some suitable material, such as cork, this packing being arranged to bear upon the flange 11- around the churn-opening. This flange b is pressed into the packing by the locking devices, hereinafter described, so as to form a perfectly tight joint and effectually prevent leakage. Formed integrally with the frame 0 are pivotal pins d, two of of which project laterally from each sidebar of the frame in close proximity to the lugs b Two levers e e are employed to lock the cover rem ovably in place, both of these levers being provided with oppositely extending arms 6 whose outer ends are turned downwardly, as at 6 and pivoted on the outwardlyprojecting pins cl, the parts a being shouldered to catch under the adjacent lugs 11 of the stationary frame when the levers are thrown toward each other. The lever e is straight and provided with a longitudinal slot f near its lower end, while the forward. end of lever e is curved forwardly and downwardly, and provided with a longitudinal slot f, a curved notched latch f being adj ustabl-y secured in the slot in the curved part of the lever by means of a bolt and nut.

To look the cover in place it is simply necessary to place it over the opening between the lugs 11 and turn the levers toward each other and lock them together by pressing the lever a over the other lever, so that the curved notched catch will pass through the slot f and engage the upper end of the same, this action serving to engage the shoulders of the arms a under the shoulders of the lugs 12 and press and hold the cover upon its seat, the leverage exerted to press the cover being comparatively great. The arms a give sufficient elasticity to the levers to enable them to spring into engagement with each other when pressed together and to firmly lock them together during the movements of the churn-body.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a churn-body having stationary shouldered lugs 12 upon opposite sides of its opening, of a cover fitting over the opening between the lugs, levers e andf,

provided with arms 8 these arms projecting outwardly in opposite directions and having their ends turned downwardly and pivoted upon the side edges of the cover near the lugs b the levers e and f being bent toward each other and detachably connected together at their upper ends, substantially as described.

2. The combination of a churn-body provided with lugs 19 upon opposite sides of its opening, a cover fitting over said opening, arms e pivoted on the side edges of the cover and shouldered to engage under the lugs 11 levers e and f, connected to the arms 6 one of these levers being provided with a notched catch adapted to engage the other lever when the two are pressed together, substantially as described.

3. The combination, with a churn-body having stationary lugs 1) upon opposite sides of its opening, of a cover fitting over the opening 20 between the lugs, and levers provided with oppositely-projecting arms, these arms being In testimony whereof Iaffix my signature in 0 presence of two witnesses.
