JOSEPH SAILER, 0F OXNARD, CALIFORNIA.

SEPARATOB.

Application led December 1G, 1914.

To all whom it may concern.'

Be it known that I, JOSEPH SAILER, a citizen of the United States, residing. at Oxnard, in the county of Ventura and State of California, have invented a new and useful Separator, of which the following is a specification.

This invention comprehends improvements in separators and relates more particularly to what I term ahydrotrash separator.

Y The machine is particularly designed for use in separating beet chips and small fragments of beets from leaves, tops and other matter with which they are mixed.

In the beet sugar industry there is a large production of what is known as trash, this trash consisting of leaves and other foreign matter. This trash is commonly mixed with small pieces of beets, beet tails, and tops. The proportion of beets contained in the trash is quite considerable, and the loss to a sugar beet factory through the discarding of masses of trash amounts to a considerable amount. By the use of my invention it is possible to separate small pieces of beet, tailings, and chips, from the trash, the valuable portions of the beets being afterward utilized so that considerable savings are effected thereby.

One of the objects of the invention is to provide a water separator comprising a tank into which the trash is dumped, and means for setting up water currents which will float the leaves and stems and discharge them over the overflow edge of the tank and which will carry the valuable portions of the trash toward the center of the machine where they are picked up by a conveyer.

With these, and other objects, in'view, the invention consists in certain features of construction, combination and arrangement of parts as will be hereinafter described, illustrated and claimed.

Figure 1 is a top plan view of the separator; Fig. 2 is a side elevation, partly broken away and partly in section; Fig. 3 is an end elevation of the separator showing conveying means for the trash; Fig. 4 is a transverse sectional view taken through Fig. 2 on a line midway between the center and the extreme right end of the trough shown.

Referring in detail to the drawings by numerals: 1 designates as an entirety the tank which, it will be understood, may be Y carried in the tank.

Specification of Letters Patent.

Serial No. 876,450.'

'gitudinally through the center of the tank in such a position that it is approximately in the center of the mass of trash which is The agitating pipe 7 is flanged at one end, as indicated by the numeral 8 and bolted to a flange 9 on a revoluble hub 10 which is driven by a belt wheel 11. The other end of the agitating pipe 7 projects into a stuing box 12 and Y water or air may be forced into this open end by means of a pipe 13 having a valve 14:.

At one end of the tank below the pipe 7 is provided a fitting 15 having a water inlet 16 and a flushing valve 17. This fitting opens into the tank near the bottom thereof and serves either as a means for injecting water into the tank or drawing water therefrom. At the other end of the tank in line with the fitting 15 a water inlet 18 is provided so that water may be forced therethrough toward the center of the tank along the bottom thereof.

To provide for setting up a current of water flowing toward the overflow edge 6 I employ a horizontal trash moving pipe 19 which extends longitudinally of the tank and `which is positioned near the rear wall. This pipe is connected at its open end to one end of the tank by a couplino' 20 and this open end is fed by a pipe 21 equipped with a valve Pipe 19 has a series of openings 23 formed therein, this pipe being so located, and the perforations 23 being so placed, that a stream of fluid ejected through the perforations 23 will act on the upper part of the mass of trash for the purpose of moving the trash across the tank and through the overflow opening.

The heavier particles composed of small pieces of beet, beet tails, and chips which fall to the bottom of the tank and which are caused to gather at the center thereof by incoming streams of water flowing through the inlet 18 and fitting 15 are carried away by means of a spiral conveyer 24. This conveyer extends upwardly at any suitable angle and is incased in a water tight housing or casing Q5 which encircles a dischargeopening 26 formed in the bottom ot the tank. The lower end ot the conveyer shaft 2T revolves within a thrust bearing 28 as fully shown in Fig. e. rhe casing' Q5 is preferably provided with a clean-out door 29 on its lower side near its lower end.

In operation the mixture ot' trash, beet tailings, and chips is conveyed to the tank l by any suitable means such as the endless conveyer 30 and diunped into the open top ot the tank. lVater flowing into the tank through the fitting l5 and intake 18 will cause a current toward the center ot the tank which will carry the heavy particles as they fall dovinwardly toward the discharge opening 26. The upward .torce of the current olfwater 'from the itting l5 and the intake 18 holds the trash in suspension, but this torce is not sutlicient to hold the heavier particles, consisting of heet tailings and chips, these beet tailings and chips tallu ing to the bottom of the tank. ylfhe revolving hollow shaift Y will cause the water discharging into the tank through the pert'orai tions therein to set up an agitation within the tank which will tend to separate the leaves, stems and other light matter from the heavier particles oi^` beets, and the water issuing trom the pertorations in the pipe l) will set up a current toward the overflow edge so that the light particles are discharged thereover with the overflow of water.

It will be understood that air may be forced into the tank to the pipes it' desired and the currents oi' air will cause a proper agitation et the water so as to separate leaves and stems from the heavier particles.

From the foregoing description taken in connection with the accompanying drawings, it will be apparent that I provide a very simple and practical segiarator and it will he understood that changes in constructicn and arrangement ot parts may be made without sacrificing' any of the vital features ot the invention, provided ot course, that such changes fall within the spirit and scope ot the appended claims.

What I claim is:

l. In a separator for removing pieces of beet from trash in the manufacture oit beet sugar, the combination ot a tank in which the trash is immersed in water, said tank having one side slightly lowered to Jform` an overflow edge, means tor agitating the trash in said tank, means tor forcing waste matter from said trash over said overflow edge, and means for withdrawing pieces of beet from the center of the tank.

2. In a separator for removing pieces of beet from trash in the manufacture of beet sugar, the combination ot a tank in which the trash is immersed in water, said tank having one side slightly lowered to form an overflow edge, a perforated agitating pipe extending through the center' of said tank, means Yfor 'forcing a fluid through the perorations in said pipe to agitate the mass ot trash in said tank, means for forcing waste mattei' trom said trash over said overflow edge, and means 'for forcing the pieces ot beet that settle to the bottom olf the tank toward a discharge opening through which said pieces are withdrawn.

In a separator for removing pieces ot' beet from trash in the manufacture of beet sugar, the combination of a tank in which the trash is immersed in water, said tank having one side slightly lowered to form an overflow edge, means tor agitating the trash in said tank, a trash moving pipe extending across said tank at a point opposite said overiiow edge, said trash moving pipe having trash moving perforations therein on the side toward the overow edge, means for forcing a liuid through said trash moving pertorations in such a manner as to torce the lighter portions ot said trash over the overflow edge, and means for withdrawing pieces of beet from the center of the tank.

In testimony whereof, I have hereunto set my hand, at Los Angeles, California, this ll-th. day of December, 191er.
