SPECIFICATION forming part of Letters 4Patent No.714,315, datedNovember 25, 1902.

. Application filed February 24. 1902. Serial No. 95,293. (No model.)

To all whom it mayconcern.- t

Be it known that I, JOHN F. LYBRINK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi# nois, have `invented certain new and useful Improvements in Mixing-Tanks; andI `do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to mixing-tanks designed especially -for thoroughly mixing varnish, paints, or the like; and it consists of certain novel features of combination and construction of parts, as will be hereinafter fnlly described and claimed.

The object of my invention is to provide a mixing-tank which will thoroughly incorpoconstruction of cooperating parts.

ous parts of my invention and coperatingl rate the ingredients employed in producing amost perfect varnish or paint.

A further object of my invention isto ef# feet a thorough mixing of the ingredients employed at the expense ofa minimum amount of power. y

Other objects andadvantages will be made fully apparent from the following specification, considered in connectionwith the accompanying drawings, in which- Figure 1 is a side elevation ofV my invention complete. Fig. 2 is a longitudinal sec tion of the same on a; reduced scale. Fig. 3

`is a central section of Fig. 2 online `c 0c. Fig.

4 is a similar view to that presented in Fig.

I3, showing the inner blades greatly limited in number and disposed at right angles to `the contiguous surface of the tank. Fig. 5

is a side elevation showing a slightly-varied Fig. 6 is a longitudinal section of Fig. 5.

In order to conveniently refer to the variaccessories, numerals will be employed, of which 1 indicates the body portion of my improved mixing tank, which is preferably made cylindrical in form, as shown in Fig. 1, and is so mounted upon the supportingshaft 2 that said shaft will be eccentric to each head 3 of the cylinder.

By reference to Fig. 2 it will be observed that when the body portion of my improved tank is disposed in a horizontal position the shaft 2 will extend therethrough on an obany preferred way.

lique line, and in order to prevent leakage around the shaft. I provide 4suitable stuffingboxes 4, as clearly shown in Fig. 2, it being understood that when the cap 5 is turned home in its threaded seat the packing 6 will be thoroughly compressed around the shaft,

'upon the supporting-standards 7, suitably formed and secured in an upright position in One end of the shaft 2 is of sufficient length to extend outward to receive the driving-pulley 8, which is keyed fixedly to the shaft or theend ofthe journal,

as the case may be, and by means of which power is applied to rotate the mixing-tank 1,

`as will be clearly obvious.

I have provided, as shown in Figs. 1, 2, 5, and 6, a suitable receivingoriiice or mouth 9, having a retaining-cap 10, by means of which the contents of the tank will be held against leakage. A suitable air-vent is provided, as indicated by the numeral 11, said vent being provided with a closing-valve 12. I also` provide the faucet 13 and the Valve 14:,` `by means of which the contents can be withdrawn at any time wholly or in any desired quantities. I prefer to provide the inner surface of my improved mixing-tank with a plurality of shelf-like blades 1.5, preferably extending at right angles to the contiguous part of the inner surface, as fully shown in Fig. 4, though, if preferred, a greater number of said blades, as indicated by the numeral 16, may be provided, and said blades may be obliquely disposed` with respect to the contiguous surface ofthe tank to which they are attached, and while I have shown both forms of construction I desire to employ either form as I may see fit in practice to use.

It will of course be understood that the plurality of agitating- blades 15 and 16 may be connected to the interior surface of my improved tank in any preferred wayhas, for

. and thus cause the body 1 to turn therewith Ico instance, the same may be seated in a suitable recess, or said blades may consist of suitable angle-iron properly riveted to the internal walls, as clearly shown in Fig. 6.

I have also illustrated that the faucet 13, by which the contents may be removed in any desired quantities, may be connected directly to one of the end sections, though I prefer to connect said faucet upon the side, as shown in Fig. 5, and upon that side of the tank which will be in a true horizontal position when the tank is at rest. The faucet may be placed slightly to one side of the central horizontal line, or the inner end of the faucet may extend a few inches, more or less, beyond the inner surface of the side wall, if desired, in order that said inner end will extend through the accumulation of sediment usually composing the lower strata of the contents, inasmuch as by said arrangement such sediment may be left undisturbed in the tank, while the contents above the sediment may be freely withdrawn. in Figs. 5 and 6 that one of the end sections or heads may be provided with a suitable manhole and a proper closure therefor which will retain the contents against leakage, the object of said manhole being to enable the interior parts to be examined, repaired, or replaced, as may be necessary from time to time so to do. The construction of the body portion, as shown in Figs. 5 and 6, will therefore be found to be less expensive than the construction illustrated in Figs. 1 and 2, and I wish, therefore, to reserve the right to adopt either form of construction in practice as I may nd most desirable and productive of the best results.

The contents may be introduced into the tank through the receiving-mouth 9 and the cap tightly secured in place and the valves 12 and 14 properly closed. The pulley attached to the driving-shaft 2 may then be rotated by any suitable variety of power, when it will be observed that the contents in the cylindrical body 1 will be most thoroughly agitated and the component parts thereof commingled with each other to the desired degree to produce a perfect varnish, paint, or the like. The contents will not only be engaged and agitated by the plurality of blades 15 or 16, as the case may be, but will also be directed by gravity rst from one end of the tank to the other until the process is complete, when the contents may be wholly or partly withdrawn, as desired, from the faucet 13. It is obvious that in order that the flow Ihave also shown v of the contents through the faucet 13 may be facilitated the valve 12 may be opened in order to admit the requisite quantity of air into the tank.

Having thus fully described the construction and manner of using my improved mixing -tank, further reference to the details thereof is deemed unnecessary.

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

1. The herein-described mixing-tank comprising a body portion, a supporting-journal for each end of said tank disposed eccentrically to the longitudinal axis of said body portion, with the ends of the tank in parallel planes, and suitable internally-disposed agitating-blades carried by said body portion, a shaft extending through the body portion and through said journals, supports for said shaft and means for rotating the same, substantially as described.

2. A tank having its ends provided upon the interior with integral journals disposed eccentrically to the longitudinal axis of the tank, stuffing-boxes upon the outside of the ends of said tank in aline ment with said journals and a shaft passed through said journals and stuffing-boxes, and secured to the former within the tank, supports for said shaft and means for rotating the same.

3. A tank having its ends provided upon the interior with integral journals disposed eccentrically to the longitudinal axis of the tank, stuffing-boxes upon the outside of the ends of said tank in alinement with said journals and a shaft passed through said journals and stuffing-boxes, and secured to the former within the tank, and said journals being integral with the ends of the tank, supports for said shaft and means by which said shaft may be rotated.

et. The herein-described mixing-tank comprising a body portion with eccentric journals, a vent at one end, a faucet at one end, a filling orifice and closure therefor, blades up'on the inner Walls of said body portion, supports for said tank, a shaft passed through said body portion diagonally to its axis and secured to the body portion, and means on said shaft whereby it may be rotated, substantially as described.

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

JOI-IN F. LYBRINK.
