TILTING TANK FOR RECEIVING OR DISCHARGING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 621,982, dated March 28, 1899.

- I Application filed May 5, 1898. Serial No- 679,807. (No model.)

To all whom it may concern:

Be it known that I, GEORGE T. TILDEN, a citizen of the United States, residing in Milton, in the county of Norfolk and State of Massachusetts, have invented a new and Improved Tilting Tank for the Reception or Discharge of Liquids, of which the following is a specification.

This construction comprises a tank for receiving, holding, and discharging water or other liquid, the said tank comprising two separate and distinct chambers similar in form, but reversed in position relative to each other. The tank is sustained upon a knifeedge or other suitable pivotal support, so'

that it may be readily tilted from one side to the other without losing its proper relation to the supply-duct, which is located centrally above it. The two chambers are separated by a partition common to both, and this partition is centrally formed into oppositely-inclined troughs or guideways set side by side and leading into their respective chambers, thus converting a small portion of the dividing-wall between the tanks into a partition between and common to .both of the troughs, such partition running at right angles to .the long axis of the double tank.

WVhen the supply-duct is properly located above the tank, its discharge is received by one or the other of the troughs, and'thence.

conducted into one or the other of the chambers, according to the position of the tank, the chamber receiving the inflow of liquid being that which is uppermost. When the liquid thus received in this chamber has reached such a level as to overbalance the tank, the said chamber is tilted down by gravity and discharges its contents, thus swinging up the other chamber into position to receive the' inflow, and the process just described is repeated by the latter chamber. Thus the tank receives the liquid into its chambers alternately and discharges such liquid intermittently-that is to say, from the chambers alternately and at opposite ends of the tank.

This is accomplished without the employment of 'siphonic action, as was the case in the invention described in Letters Patent of the United States, numbered 576,006, granted to me January 26, 1897.

This improved tilting double tank may be used in supplyingwater to water-closets, for emptying receptacles containin sewage, and

in many other positions and conditions where a strictly-speaking intermittent, but practically (if desired) continuous, discharge of water or other liquid is required.

Among the objects of this improvement are the prevention of clogging which is often incident to the employment of siphon-tubes and economy of construction.

The nature of my invention is fully described in detail below and illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of my improved double tilting tank with one chamber in position for receiving the inflow and the other chamber in position for discharging. Fig. 2 is a longitudinal vertical section taken on line X, Fig. 1. In this figure the location of the supply-duct is indicated, and broken lines illustrate the position of the tank when tilted in the reverse direction.

Similar letters of reference indicate corresponding parts.

A and B represent, respectively, the outer walls of two similar tanks placed side by side and rigidly connected or united, but so set with relation to each other that the discharge end of each tank projects beyond the opposite end of the other tank.

0 represents a substantially vertical partition between and common to both tanks. By this means the two tanks are united, so as to constitute a double tank with two distinct and separate chambers. At 0 and 0 this partition extends beyond the deeper or inner ends of the chambers and constitutes walls of the discharging ends of the chambers.

D represents the bottom of the tank, such bottom being common to the two chambers. This bottom is transversely bent or formed upward at D, so as to constitute an obtuse angle substantially as shown, and the under surface of said bottom is preferably thickened at D and transversely grooved at D in order that the tank may be sustained centrally by a knife-edge or pivotal support S. The upper edges of the walls A B are formed at A B into angles which substantially correspond with the angle of the bottom D, and the upper edge of the partition 0 O 0 follows the same angle as the upper edges of the walls A B. The inner end of each of the reversely-set chambers is provided with an end wall E, which is preferably substantially at right angles with theside walls A B and the adjacent portions of the bottom. At the opposite end of each of said chambers the floor is formed at d at an obtuse angle into an end wall F, which when that end of the tank is tilted down lies in a substantially horizontal position or extends down slightly from such position and serves to discharge the liquid from its chambers.

The partition 0 is formed centrally into the two oppositely-extending troughs or guideways H and H, said troughs extending, preferably, down to the floor or bottom D and being separated by the partition-wall H", common to both troughs, extending transversely with the tank and located directly over the pivotal point of the bottom of the tank when the tank is exactly balanced. The deep end of each chamber-that is to say, the end between the end wall E and the points A and Bis provided with a suitable cover K, which is preferably cemented or otherwise secured in position, so as to make a water tight joint. These covers preferably extend to the points A and B, and hence conform in shape to the troughs which are formed in the partition C.

The tank being in the position indicated in the drawings, water or liquid from the duct Y flows into the trough H and thence into the cha1nber,which is shown in full lines in the drawings as being uppermost. When the liquid in this chamber has reached a sufficient level, the tank is overbalanced and tilts into the position indicated by broken lines in Fig. 2. In this latter position the water which has flowed into the forward chamher is quickly discharged over the inclined partition F, which is in a substantially horizontal position. Meanwhile the trough H is under the duct Y and the water is conducted by said trough into the rear chamber, which when the liquid has reached a sufficient level tilts down again into the position indicated in full lines in the drawings, discharging the water over the portion F. Thus a continuous stream of water from the duct Y flows alternatelyinto the front and rear chambers, and the liquid is discharged intermittently from the opposite ends of the tank quickly in large volumes an d without danger of any portion of the apparatus becoming clogged. Ofcourse these discharges may be brought to a common outlet or led oft" into diderent directions, as desired.

While this device is intended, primarily, for the reception and discharge of liquids, any other flowing materialsuch as seeds, shot, &c.which will pass through the tank by the action of gravity may be applied to it.

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

1. Atilting tank of the character described, comprising two distinct and rigidly-connected chambers similar in form but relatively reversed in position and so set with relation to each other that admission of liquid into one chamber tends to overbalance the other,

said tank being provided with a bottom ex tending across and common to the chambers and formed substantially into two longitudinal planes meeting each other at an obtuse upward angle, one end of each of said chambers projecting beyond the opposite end of the other chamber and being provided with the end wall F set at such an angle that when said end is tilted down the end wall F will lie in a substantially horizontal position and thus discharge the contents of the chamber, the tank being adapted to be supported pivotally at substantially the point where the two planes of the bottom meet, substantially as described.

2. Atilting tank of the characterdeseribed, comprising two distinct and rigidly-connected chambers separated by the partition 0 and relatively reversed in position, said chambers being provided with the common bottom D formed substantially into two longitudinal planes meeting at D at an obtuse upward angle, said chambers being each provided with a closed deep end formed by said bottom, the partition 0, outer walls A and B respectively, deep end wall E, and cover K, and being each provided with an open end formed by said bottom, the extensions C and 0 respectively of the partition C, the outer walls A and B respectively, and the end wall F set at such an angle that when the open end is tilted down the end wall F will lie in a substantially horizontal position and thus discharge the contents of the chamber, the tank being adapted to be pivotally supported at substantially the point where the two planes of the bottom meet, substantially as set forth.

3. Atilting tank of the character-described, comprising two distinct and rigidly-connected chambers separated by the partition 0 and relatively reversed in position, said partition being formed centrally into the two oppositely-set troughs H and H respectively extending into and to the bottoms of the said chambers,- and said chambers being provided with the common bottom D formed substantially into two longitudinal planes meeting at D at an obtuse upward angle, said chambers being each provided with a closed deep end formed by said bottom, the partition'C,

1 outer walls A and B respectively, deep end wall E, and cover K, and being each provided with an open end formed by said bottom, the

extensions 0' and C" respectively of the partition O, the outer walls A and 13 respectively, and the end wall F set at such an angle that when the open end is tilted down the end wall F will lie in a substantially horizontal position and thus discharge the contents of the chamber, the tank being adapted to be pivotally supported at substantially the point where the two planes of the bottom meet, substantially as described.
