PASTEURIZING APPARATUS.

Specification of Letters Patent.

Patented July 19, 1910.

Application filed April 23, 1909. Serial No. 491,716.

To all whom it may concern:

Be it known that I, JAMES W. Hniznn, a citizen of the United States of America, and resident of Wheeling, county of Ohio, and

State of lVest Virginia, have invented certain new and useful Improvements in Pas teurizin Apparatus, of which the following is a specification.

This invention relates to improvements in pasteurizing apparatus, and it has for its primary object to provide an extremely simple and inexpensive device whereby the contents of glass bottles or jars may be pasteurized or sterilized without subjecting such bottles or jars to the danger of breakage.

A further object of the invention is to provide an apparatus of the character mentioned which is particularly adapted for pasteurizing the contents of milk-modifying bottles and whereby said contents may be accurately heated to the required temperature.

A still further object of the invention is to provide a pasteurizing apparatus the construction or arrangement of which is such that a thermometer or other temperaturetesting instrument may be directly applied to the con-tents of the bottle or jar without its first being passed through a heated zone where it would be unduly influenced.

\Vith these and other objects in view, the invention finally consists in the particular coustruction, arrangement and combination of parts which will hereinafter be fully described, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a top plan view of the invention; Fig. 2 is a vertical section of the same on the line 2-2, Fig. 1; Fig. 3 is a horizontal section on the line 33, Fig. 2; and- Fig. 4 is a side elevation of the jar-holding receptacle, removed.

Referring to said drawings, in which like reference numerals designate like parts throughout the several views-1 indicates a cylindrical receptacle adapted for receiving a bottle or ar 2 containing milk, fruit, cereals, or other matter to be pasteurized or sterilized, he diameter of said receptacle being just enough greater than that of said bottle or 2 to admit of convenient or ready insertion and removal of the latter. Legs 3 carried by the lower end of said receptacle 1 serve to support the latter, as shown, said legs being inclined outward to a point where they are just receivable in an outer cylindrical receptacle 4 in which the receptacle 1 is seated and being adapted to center the receptacle 1 with relation to the receptacle 4. The lower ends of said legs have inturned terminals 3 which facilitate the insertion of the inner receptacle in the outer receptacle. The height of the inner receptacle l is preferably such that it stands slightly above the straight body-portion of the bottle or jar to be received therein, as shown. The outer receptacle 4: is made of such a height with relation to the inner receptacle and to the bottle or jar to be contained therein that its removable cover 5, when properly seated, will rest upon or closely overlie the top of the neck of said bottle or jar. Said cover has a central orifice 6 therein whose diameter is substantially that of the mouth of the bottle or jar 2, with which mouth it registers, said orifice being adapted not only to allow the usual discharge tube 7 of a milk-modifying bottle to project outward therethrough, but also to admit of the application of a thermometer, or other temperature-testing instrument, to the contents of the bottle without removing the cover, said instrument being inserted into the contents through an aperture in the bottle-stopper 8, which aperture may be either that through which the tube 7 is projected or the aperture 9 in which a blowpipe (not shown) may be seated.

In practice, the receptacle 1 is first seated within the receptacle t and the bottle 2.0011- taining the fluid to be acted upon is placed within said receptacle 1, after which the latter is filled up with cold water. The receptacle at is then filled with boiling water, after which the cover 5 is immediately seated in place. The cold water which finds its way about the sides of the bottle serves to prevent the sudden heating of the bottle which would otherwise, result from the filling of the outer receptacle with hot water; that is to say, the heating of the bottle is thereby caused to be gradual, and consequently the danger of the bottle breaking through being subjected to a sudden change of temperature is removed or eliminated.

Since it is desirable in pasteurizing to effect the heating of the fluid acted upon to not more than a certain degree of temperature, this may be regulated more or less, as

- ceptacle desired, by increasing or diminishing the quantity of cold water placed in the receptacle l, the purpose had in view in making said receptacle slightly higher than the body-portion of the bottle to be received therein being to provide a water-holding area which may, or may not, be occupied by water.

It will be noted that to test the tempera ture of the contents of the bottle, the testing instruments may be passed directly into the bottle without removing the cover 5 and without said instrument passing through a heated instrument-infiuencing area in reaching said contents, and that, consequently, an accurate test is readily obtained.-

As is well understood, when the water in the outer receptacle begins to cool, a circulation is created which carries the cooler water to the bottom of the receptacle. The legs 3 are therefore provided on the inner receptacle for the double purpose of centering the latter Withrespect to the outer re and of supporting it above the bottom of said outer receptacle where it will be subjected to the greatest heat of the water.

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

1. A pasteurizing apparatus comprising separable outer and inner receptacles, means I whereby the latter is centered with to the former, a glass bottle seated within respect the inner receptacle with its neck ing outward therefrom, an apertured stopper in said bottle, and a centrally apertured cover seated in the outer receptacle and closely overlying the top of the neck of the bottle with its aperture in register with the mouth of the bottle.

2. A pasteurizing apparatus comprising separable outer and inner receptacles, means whereby the latter is centered with respect to the former, a glass bottle seated within the inner receptacle with its neck projecting outward therefrom, the inner diameter of the inner receptacle being slightly greater than the outer diameter of the bottle body, adapting the former for containing a thin sheet of water about the bottle body, and a cover seated in the top of said outer receptacle and closely overlying the top of the neck of the bottle, said cover having an orifice therein in register with the mouth of the bottle.

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