CREAMsGAGE FOR MILK-CANS.

SPECIFICATION forming part of Letters Patent N 0. 291,296, dated January 1, 1884. Application filed April 7, iss. (No model.)

To all whom, it may concern;

Be it known that I, CLARENCE L. COLBY, a citizen of the United States of America, residing at Fairmont, in the county of Martin and State of Minnesota, have invented certain new and useful Improvements in Cream-Gages for Milk-Cans, cation.

This invention relates to cream-gages for milk-cans; and it consists in the peculiar construction of the same, substantially as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to. make and use the same, I will now proceed to describe its construction, referring to the accompanying drawings.

Figure 1 is a perspective view of part of a gage. Fig. 2 is a horizontal section of the same. Figs. 3, 4, 5, and 6 are detail views, showing the gage in different stages of construction.

A represents a milk-can of the usual form provided with a cream-gage, B. This gage is stamped from asingle piece of metal, with the opening a and flange b at the sides and ends. These flanges are bent or stamped inward the thickness of the glass panel 0, and then at right angles to form the wings 6. These wings b are then bent at a point, which will of which the following is a specifistill leave narrow but now double wings or projecting flanges backward over themselves, and extending to the opening a, in order to hold the glass panel in place when inserted, as seen at 0. In making the gage, having struck out the blank and made the opening a, the gage marks and the flanges b and the wings b are stamped out at one operation, leaving a depression for, and the thickness of, the glass panel to be inserted. Having the wings I) bent as before shown, the glass is inserted, and by pressing tightly together the double portions of the flanges or wings I) the extended part is bent down upon the glass panel, pressing it against the flanges b on the reverse side and holding so firmly and tightly as to prevent the escape of liquid. The gage is then passed through an opening in the side of the can from the inside, with the double flange or wings I) resting against the body of the can, forming a tight joint inside, and leaving nothing for the milk to cling to. The inside surface is smooth and does not interfere with the perfect cleaning of the can. The gage is secured in place by having its glass panel or raised portion passed through the opening made in the side of the can and its flanges resting against the inside of the main body of the can, as represented in Fig. 2. It is then soldered to the can, the melted solder spreading out under the flanges, and a tight joint formed, while at the same time no uneven projections are formed which are difficult to clean, and thus injure the fresh milk when poured into the can. It will be understood that the flange extends entirely around the gage or panel, at the ends as well as the sides, made entirely as just described.

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

1. In a cream-gage, the combination of the can formed with an opening in itsside, of the blank or frame B, stamped from a single piece of metal, with the usual gagemarks, the flange 6, opening a, and wings I), and glass panel 0, the said wings being bent over backward upon themselves at a point so as to leave a narrow projecting double flange or wings b, extending and overlapping the glass panel a, substantially as and for the purpose set forth.

2. In a cream-gage, the combination, with a transparent frame, of a sheet-metal frame formed with the opening a and flanges b, said flanges being bent outward and then back upon themselves,and overlapping the panel, thus forming wings 1), adapted to be secured to the sides of the can, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

CLARENCE L. COLBY.
