IMPROVEMENT IN GRADUATED MEASURES.,
Specification forming part of Lettrrs Patent No. 150, [854, dat( d April 28, 1874; application Iiled April 10, 1874. v
To all whom it may concern Be it known that I, ALONZO MONTGOMERY OSMUN, of Sunbury, in the county ot N orthumberland and State of Pennsylvania, have invented certain new and useful Improvements in Liquid-Measure, and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to Which it pertains to make and use the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, Which forni a part of this specification.
This invention relates to an improvement in liquid-measures; and consists in constructing a measuring-vessel of tin, Wood, or other material easily tarnished or Worn, with sloping sides, and letting into openings therein strips of copper or brass flush with the interior surface, and graduated to show the contents of the vessel.
There are upon the market at present numerous graduated measurin g-vessels but none of them, so far as I am aware-exactly meet the requirements of dealers in a variety of liquids and semi-liquids, such as icecream, molasses, and oil, as most of them have grooves or projections on their interior surfaces, which retain more or less ofthe substance measured therein, and are very difficult to clean. y
In my invention the graduated copper or brass strips are let into openin gs of corresponding size and shape, and firmly secured therein by soldering, the solder serving to protect the edges from Wear and corrosion. A smooth surface is thus produced, Which is very easily scoured and kept clean, and retainsthe least possible amount on pouring any substance from the vessel.
rhe body of the vessel being of tin, Wood, or other material easily tarnished, and the graduated strips only of copper or brass, it is not necessary to break the surface of the material of which the body of the vessel is constructed by cutting the graduations directly thereupon, and thus giving a starting-point for corrosion and Wear, but the graduations are cut upon the copper Or brass,\vhich, being durable metals, and not simply coated, but homogeneous, can be thoroughly cleaned by scouring. The strips are also of different colors from the body of the vessel, and may be brightly polished, so as to be easily observable.
B y this construction I am enabled to furnish a graduated measure equal to one made cntirely of copper, brass, or other valuable metal, and at a far less cost.
In the drawings, Figure l is a sectional view of a measuring-vessel constructed according to my invention. Fig. 2 is a section taken through the dotted line a: x of Fig. l.
A is the body of the vessel. B B are the strips let into openings therein. G is a strip, which may be of the same material as the body of the vessel, and serves to prevent the strips from being forced out in cleanin 0. This strip may be dispensed with, but I prefer to use it.
Having now described my invention, I claim- As a new article of manufacture, a measuring-vessel made of tin, Wood, or other Inaterial, and having graduated strips ot' copper, brass, or other durable metal let into openings therein, and flush with the interior surface thereof, substantially as described, and for the purpose set forth.
In testimony that I claim the foregoing as my own invention, I atlix hereto my signature in presence ot' two Witnesses.
