JAMES MCADAM, OF POSTVILLE, IOVA.

BUTTER-TU B.

SPECIFICATION forming part of Letters Patent No. 357,936, dated February 15, 1887..

Application iled November l5, 1886. Serial No. 218,962. (No model.)

To @ZZ whom t may concern,.-

Beit known that I, J .inns MCADAM, a citi zen of the United States, residing at Postville, Allamakee county, and State ot' Iowa, have made certain new and useful Improvements in Butter-Tubs, of which the following is a speciication.

In the drawings, Figure l is a perspective View of my improved butter-tub; Fig. 2, a vertical section, and Fig. 3 a perspective View, of a portion of the tub, enlarged to more clearly illustrate the fastening.

A is thel butter-tub; B, the cover, C, a wooden piece to strengthen and re-enforce the cover; D, the fastener for the cover, and E a pivoted portion of such fastener by which it is tightened .or loosened.

In making my improved butter-tub, which is intended to be an improvement on that described and shown in Letters Patent of the United States,No. 309,969, issued to me December 30, 1884, and on the butter-tub described and shown in application Serial No. 205,276, led by me June 15, 1886, which has been al-` lowed but not yet issued, I make the buttertub with a cover depressed as shown in those patents and as shown in the drawings herein; but as the fastening device shown and described in my other patents, although practical and useful, does not wholly satisfy the demands of customers, I have adopted the form shown in my drawings herein.

Instead ot' employing a tongue that passes up through a slot in an outwardly-extending iiange, I make a hook or clasp, D, adapted to t down upon and securely clasp the rim of the tub-top. The lower end of this hook is extended and pivoted to a piece, E, which piece is in turn pivoted at some distance from its end to the side of the butter-tub. As it is turned so that the end pivoted to the extended portion of the hook D is raised or lowered, it will of course correspondingly raise or lower the hook. side of the tub at a proper distance from the top, itsend pivoted to the hook D will draw If the piece E be pivoted to the it down firmly and securely upon the rim of the cover, so as to hold it in place at the time the upper end is brought between the piece D and the side of the tub. The course of the piece E when being thus turned into place is shown by dotted lines in Fig. 3. Thus when the top is brought firmly and tightly into position on the tub, the lever portion of the piece E is turned in directly between the piece D and the side of the tub, so as to be out of all danger of being struck and thrown out of position in handling or shipping the tubs, and all danger of accidentally loosening the top of the tub is thus avoided. The essential idea contained in this method of fastening is the employment of a piece pivoted to the tub,

which, as it is turned in one direction, will.

bear the fastening or claspiug piece down firmly against the top ofthe tub, so as to bring it and hold itin place, and as turned in the otherdirection will either raise the fastening-piece itself or permit it to be raised by hand. I say permit it to be raised77 because it is obvious that the piece which exerts the leverage or bearing power, and by which the fastener is brought down, need not be actually pivoted to that piece, but simply bear against a shoulder or other projection thereon. I have made them without actually pivoting the two pieces together; but I prefer the form ywhich I have described above and illustrated in the drawings, and simply make this explanation in order that I may not be unnecessarily limited to the strict details of the form shown.

Vhat I regard as new, and desire to secure by Letters Patent, is

The combination, with a tub having a lid or cover, of a fastening-hook and a pivoted piece or lever drawing such hook into position to hold the lid in place when turned in under the hook and freeing it when turned out from under the hook, substantially as described.
