PASTEURIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 781,860, dated February 7, 1905.

Application filed September 5, 1903. Serial No. 172,041.

To (LU whom it may concern:

Be it known that I, \VALTER B. \Varerrr, a l

citizen of the United States, residing at Chicago, in the county of (look and Stateot' lllinois, have invented a new and useful Improvement in Pasteurizing Apparatus, of which the following is a specification.

My invention relates to an improvement in the class of apparatus employed for pasteurizing beer in bottles by supporting the filled bottles upon trays pivotally mounted on endless chains to travel through a holder containing water at different degrees of temperature in different parts or zones, through which the bottles are caused to pass.

The object of my invention is to provide a generally improved construction of the apparatus in matters of' detail; and it consists in the combination of parts hereinafter described. and pointed out in the appended claim.

Referring to the accompanying drawings, Figure 1 is a view in side elevation, partly sectional, of a known general form of pasteurizing apparatus provided with my improvements; Fig. 2, a section taken at the line 2 on Fig. 1 viewed in the direction of the arrow and enlarged, showing pulley details; Fig. 3, a view showing two of the three sections in which 1 construct the apparatus fitted together with the casing or holder in longitudinal vertical section and the mechanism within it in elevation, and Fig. l a similar view of the third section of the apparatus disconnected from the other two sections thereof.

A is the holder, which my construction enables me to form of a single wall of metal in three sections A, A and A, flanged where they fit together. The section A is of the substantially rectangular shape illustrated, with the inner wall (1 extending upward only part way to the upper wall 7) and having its upper end portion turned, as at a, to extend at an angle to the wall a. The section A is of the same general form with its inner wall 11 extending only part way to the upper wall 7) and turned, as to its upper end portion, at /",to extend at an angle to the wall a,whereby when the two sections A and A are put together to abut at their flanges r r they form the air-space B between them and the restrict- 5 ed connecting-passage 0 between the sections over the air-space. The end wall If of the section A extends short of the base-wall b" of that section and is turned outward at its lower end, as at m and provided with a flange 1* to 55 form the restricted passage 0' for communication with the scction A. This section, which is open at its top, is also of' general rectangular shape, but higher than the other sections, which are both of' the same height, and 0 its inner side wall 1/ extends short of the basewall I) and is turned at its lower end to an angle, as at w, and provided with a flange r to meet the flange at .1 and form a continuation of the passage 0. The structure is shown to 5 be surrounded at intervals with reinforcingribs 0, represented in channel-iron form. The neck at .1 connecting the sections of the passage C, forms an air-space B between the sections A" and A. By the sectional construc- 7 tion of the holder A thus described, producing the air-spaces B and B, free circulation of air about the sections is afforded to tend to maintain the water contents of the holder at the desired different temperatures in the sev- 75 eral sections, and all necessity of providing the structure with a double wall for insulating it is avoided, with the advantages of materially decreasing the expense of construc tion and of more effectually maintaining the SO varying temperatures in the different parts of the apparatus.

An overflow-pipe leads from near the top of the section A into the same near its bottom, where a steam-jet pipe 1/, containing a 5 shut-off valve (1, enters the overflow-pipe for the usual purpose hereinafter explained. A shaft 1 is journaled in the holder-section A and carries on one projecting end a cog-wheel w, meshing with a pinion on a countershaft 9 6 carrying a worm-wheel a, engaged by a worm on the d rive-shaft which carries a belt-pulley f. \Vithin the section A the shaft 0 carries a pair of similar sprocket-wheels 5 and on a frame structure 1), extending above 95 the open top of the holder-section A, is journaled a shaft /1., carrying a pair of similar sprocket-wheels y. Only one each of' these sprocket-wheels is shown, owing to the nature of the views selected for illustration. An endless chain E passes about each set of the sprockets g and g, and these chains extend through the holder in parallel relation to each other over sprocket-pinions '21 i, journaled in suitable positions therein, and within the section A the chains travel on opposite sides of a vertical central diaphragm F, reaching horizontally through the passage G into the section A this diaphragm extending downward from an agitator or stirrer Gr on a shaft It", journaled in the holder-section A and carrying on a projecting end a fixed pulley 7c and an idler-pulley k Fig. 2. A similar agitator G is provided in the sections A on a rotary shaft Z, carrying on one projecting end abelt-pulley Z. A drivepulley m is provided adjacent to the pulley Z on the holder-casing and carries a beveled gear m, engaged by a beveled pinion m on an extensionf' of the driving worm-shaft f. An endless rope H passes from the pulley on about the idler k thence about the pulleysZ and k to the pulley m, whereby driving the latter from the shaftf in the direction of the arrow on that pulley drives the rope, as indicated by arrows, to rotate the agitators G G.

Atl are represented the usual skeleton trays for the bottles not shown) on hangers n, pivotally suspended at intervals on the chains to support between them the trays and adapt the latter always to maintain an upright position.

The operation is as follows: The bottles, the contents of which are to be pasteurized, are loaded upon the trays I as they attain in the travel of the chains E the upper end of the holder-section A at which a platform (not shown) may be provided for the supply of filled bottles to be loaded and for the workmen in loading and unloading them. The holder, which is vented through a pipe (Z is filled with water to the line of the overflowoutlet (F in the section A and the steam injected from the pipe (Z into the body of the water keeps it hot in the section A, while that in the section A is cooler and that in the section A still cooler or about the temperature of the surrounding atmosphere. The driving speed of the chains E is very slow, and the driving connection with the stirrers G and G actuates them to maintain an easy circulation of the water through the holder to assist in maintaining therein the desired variations in temperature in the three sections. The bottles loaded upon the chains pass downward in the holder-section A along the outer side of the diaphragm F into the water at about atmospheric temperature to avoid breaking the bottles by suddenly subjecting them to a temperature that is too high. As the bottles pass downward through the passage G into the section A the temperature of the water through which they pass increases until they enter the section A, wherein the water is hottest and wherein the pasteurizing effect is exerted. As the bottles travel in the contrary direction through the passage G into the section A and through the passage G into the section A the temperature of the water gradually decreases until the bottles are delivered along the inner side of the diaphragm F to the upper end of the last holder-section, where they are unloaded from the trays as they emerge from the apparatus.

The diaphragm F and the agitators G and G, respectively, near its opposite ends, are important elements of my improved construction, for they cooperate with the conveyer E to effect the travel of the bottles on entering the apparatus along one side of the diaphragm through a temperature approximating that of the surrounding atmosphere and on delivery from the apparatus on the opposite side of the diaphragm through a similarly low temperature. These temperatures of the water toward the points of introduction and egress of the bottles at the upper end of the section A of the apparatus are superinduced by the action of the agitator G, which tends to circulate the water from the warmer zone thereof in the apparatus along the upper and inner surface of the diaphragm, and by that of the agitator G, which carries the water on the outside of the diaphragm upward and into the chamber in front of the diaphragm.

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

In a pasteurizing apparatus of the character described, the water-holder built in sections forming restricted passages, at which they are secured together and through which the sections intercommunicate, and air-spaces between the sections, with the section at one end of the apparatus open at its top, a conveyer traveling through the apparatus, a diaphragm extending vertically and centrally through said end section and into the section adjacent to it, and agitators in said last-named two sections, substantially as and for the purpose set forth.
