LOCK FOR CHURN COVERS.
APPLICATION FILED MAII. 6. I9'I8.

THEODORE In VALEBIUS AND OLAF LARSEN, OF FORT ATKINSON, WISCONSIN, ASSIGNORS TO THE CREAMERY PACKAGE MFG. COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
LOCK FOR CHURN COVERS.
Appoation filed March 6,
To all whom t may concern.'
Be it known that we, THEoDoRE L. VALE- RrUs and OLAF LAnsnN, residing at Fort Atkinson, in the county of Jefferson and State of Wisconsin, have invented certain new and useful Improvements in Locks for Churn Covers, of which the following is a specification.
Rotary churns are provided with cylindrical bodies formed of wood, the body having an opening in its cylindrical wall through which cream, wash water and salt are placedy in the churn and the butter removed.
rIhe present invention relates to an improved cover for such an opening and to improved means for locking the cover in closed position.
In the accompanying drawings, Figure 1 is a plan view of a construction embodying the features of our invention. Fig. 2 is a sectional view taken in the plane of dotted line 2-2 of Fig. 1. F ig. 3 is a section on line 3 3 of Fig. 1. Fig. 1 is a fragmental sectional view on dotted line 2-2 of Fig. 1, on an enlarged scale.
In Fig. 2, A denotes a portion of the cy` lindrical wall of a churn. In said wall is formed an opening B. A frame 1 is rigidly secured to the wall A, said frame comprising a flange 2 that overlies the margin of the opening B and is rigidly secured to the wall A in any suitable manner. The inner portion 3 of the frame 1 is depressed, and in said inner portion is formed an oblong opening 4 that afiords access to the interior of the churn.
The cover 5 for closing the opening a is hinged to the frame 1 in a suitable manner. Herein the cover is shown as secured to two hinge members 6 which are pivotally se cured to the frame 1 at 7 the hinges being located at one of the longer sides of the cover. The cover 5 is provided with a marginal packing strip 8 of any suitable material, which, when pressed against the inner portion 3 of the frame 1, forms a tight joint between the cover and the frame.
The means for locking the cover 5 in closed position comprises a plurality of arms pivotally connected to the cover and adapted to be forced beneath lugs on the frame 1. so as to hold the packing 8 tightly against its seat. In the present embodiment of the invention, there are two sets of arms, the
1918. Serial No. 220,734.
arms of each set being rigidly connected together and the two sets beino arranged to be simultaneously moved. *ach set 'consists of three arms 9, 10 and 11, the. arm 9 being arranged to bear against the 'side of the cover `opposite to the hinges, the arm 11 being arrange to bear against the cover adjacent to the hinges, and the arm 10 being arranged to bear against the end of the cover. rIhe arms 9, 10 and 11 are rigidly connected together and are pivotally secured to the cover by means of a screw-stud 12. The end of the arm 9 is beveled and is arranged to be forced beneath a locking lug k13 on the frame 1. The ends of the arms 10 and 11`l are similarly beveled and are arrangedvto engage beneath locking lugs 14 and 15, respectively, on the frame.
Rigid witlieach set of arms 9, 10 and 11 is an arm 1G extending at right angles with the arms 9 and 11, and provided with a segment 17 that meshes at all times with a pinion 18. The pinion 18 is provided with a pivot or journal 19 which is rotatably mounted in a central bearing 20 on the cover 5. The pinion is held against endwise displacement by means of two curved plates 21 secured to the arms 16 and overlying the teeth of the segments 17 and the pinion 18.
Any suitable means may be provided for turning the pinion 18 to swing the two sets of arms 9, 10 and 11. Herein is shown what is, in eilect, a double-handled wrench, the handles being represented at 22 and the `middle portion o the wrench having a serrated opening 23 to fit upon a similarly serrated member or pinion 24 formed integral with the pinion 18. "The member 24 is made inthe form -of a pinion merely for convenience of manufacture. secured to the upper end of the member 24 and overlying the central portion of the wrench to secure the wrench to said member. It will be seen that by rotating the wrench, the two sets of arms' 9, 10 and 11 will be pivotally moved into and out of engagement with the locking lugs 13, 14.1. and 15. When it is desired to gain access to the interior of the churn for any purpose, the wrench is turned in the direction to move the arms 9, 10 and 11 out of engagement with the locking lugs, whereupon the cover may be swung upon its hinges away from the opening et.
25 is a disk s inse W hen said opening is to be closed, the cover 5 is swung into the position shown in the drawings and the Wrench turned to force the sets of arms 9, l0 and ll beneath the locking lugs 13, 14C and l5, thereby forcing the packing 8 tightly against the margin of the opening e.
Each set of arms 9, l0, l1 and 1S constitutes a cruciform lever.
lt will be seen that since the cover is hinged to the churn, ther annoyances incidental a loose or detached cover, are avoided. The locking devices, being permanently secured to the cover, are always at hand@ ready tor operation to lock or unlock the cover. rthe rigid metallic Yframe l provides a rigid and substantial seat for the cover.
W e would have it understood that the foregoing detailed description is not intended to limit our protection, the scope olf the patent being indicated in the appended claims.
