ISAACl CHAPMAN, OF HORSEHEADS, NEW YORK.

' MILK-CAN.

sPEcIirrcATIoN forming part of Letters Patent No. 264,403, dated september 12, lesa.

To all whom it may. concern:

Beit known that I, ISAAC CHAPMAN, a citizen of the'United States, and a resident of Horseheads, in the county ot' Chemung and State of New York, haveinvented certain new and useful ImprovementsiMilk-Cans;andIdoherebydeJ clare that thefollowing is afull, clear, and exact description of theinvention,which will enable others skilled in theart to which it pertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon, which form a part ot' this specication.

My invention consists in certain novel combinations ot' devices for strengthening the bottom ot' milk-cans, which will be hereinafter described, and pointed out in the specication and claim.

In the drawings, Figure 1 is a side elevation. .v Fig. 2 is a sectional elevation. Fig. 3 is a plan view of the bottom of the interior cylinder. Fig. 4, is a side elevation ot' the cover, and Fig. 5 is a detail view.

The milk-can A is provided with au inner and outer vertical cylinder, the outer wall or cylinder, E, being formed into a supportingbase and corrugated from a short distance above thebottomd of' the can to its lowest terminal "point, and it is also corrugated to form the strengthening-bands d d at'the upper part ot' the can.

F/represents the inner can-cylinder, having the bottom d', which is additionally supported and strengthened by the cross-bars h It, Fig. 3. This bottom is composed of the metallic diskf, having the circular and vertically-projecting iiange f rigidly secured thereto, the cross-bars h It being soldered to it where they intersect, and at their ends both to the diskf and to the outer cylinder, E, on the inner side ot' the same, near the base, and crossing each other at right angles underneath the bottomd. The inner can-cylinder, F, is soldered at S S to the outer cylinder, E, Where cylinder E pro- Application led February 18, 188:2. (No model.)

jects, slightly curved, over the top of that cylinder.

A represents an annular shoulder formed at the lower part ofthe neck of the can, in order to furnish a lodgmentfor the rubber or other elastic packing, a, placed thereon, and against which the cover B is caused to tightly compress when secured upon the can. 'lhe shoulder A is a continuation of the breast ot' the can.

The horizontal pins b b, rigidly secured to the cylinder ofthe cover, are adapted to tit into recesses e e. These recesses are arched over, and thus, while serving to admit the pins b b, prevent escape of the lacteal i'luid therefrom. The pins b b, in connection with the recesses, not only serve to secure the cover B upon the can, but to compress the bottom ot' the neck or cylinder ot' the cover B against the packing f a, and thereby to render the can perfectly tight against the passage ot'- the milk or atmosphere. For this 'purpose the horizontal arms of the recesses decl-ine a very slight extent from starting-point to terminus,in.order that as the cover is turned the' pins in the sockets may cause the neck or lower part ot' the cylinder ot' the cover B to compress the elastic packing with gradually-increasing force, thus hermetically tightening the can against escape ofthe iiuid.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

In a milk-can, the combination of the vertical cyiinders E and F and bottom d', having cross-bars hh soldered to the same, and to the in`ner side of the cylinder F, near its base, as and for the purpose set forth.

In testimony that I claim the foregoing as my own l hereto atfix mysignature in presence ot' two witnesses.

JAMES D. SHoo'rs.
