MEASURING TANK.

Application led Tune 27,

tion thereof.

Referring now to the accompanying drawing, forming part of this application, wherein like reference characters indicate like parts:

Figure 1 is a transverse sectional view through the tank, centrally of the supply pipe connection, illustrating the latter in section, as well as a portion of the discharge nozzle; and l Figure 2 is a perspective view of the tank and its various connections.

1 represents an elongated cylindrical tank, supported horizontally in any desired manner adjacent the mouth of a mixer or other device in which the water supply is to be used; the mixer not being illustrated in'this instance, as it does not form part of my present invention. y

In the bottom of the tank and preferably adjacent the center thereof is installed a coupling indicated at 2, whichcarries upon its upper and larger end internally of the tank the inverted frusto-conically shaped valve seat 3, and in its lower reduced end t is screw threadedly attached the water supply pipe 5. A combination valve and float stem 6 is installed within the coupling 2, it having a lowermost bearing as indicated at 7, and an uppermost bearing 8, so as to be normally held in a firm upright position and free'to reciprocate vertically. A valve 9 is attached to the stem within the coupling 2 for intermittent contact with the valve seat 3, and

a float 10 is adjustably mounted upon thel 1927. Serial N0. 201,762.

dicator lever 141-15, the latter portionfof the lever extending verticallyV through ,the collared opening 16 in the tank directly above the intake connection 2; the collar` being illustrated at 17. Upon the arm of the L-shaped lever are preferably figures, as indicated at 18, to one sideA of which are provided rather prominent dots or other forms of markings19; these being so arranged as to properly indicate the contents of the tank as the float is raised and lowered thereby. As the float isv adjustable vert-ically upon the spindle' 6 it is obvious that the quantity of liquid intermittently admitted tothe tank may be governed thereby so that any desired number of gallons, fory instance, within the capacity of the tank, may be used as a charge in establishing uniformity pf( mixture of the concrete aggregate or the The discharge thimble of the'tank'is illustrated at 20, and for convenience protrudes somewhat at an angle Lfrom the bottom of the tank, though positioned to entirely drain y tends horizontally parallel with the tank to a suitable position for convenient access b v y the operator, where itis provided with a control lever 25. J ust above this control lever and engageable thereby is the vertically reciprocable rod 26, supported in any desired manner and attached at its uppermost end`27 to the lever 28, fulcrumed as at 29 at the edge of the collar 17 about the opening 16 in the tank,'the short end of said lever extending to a position centrally over the collar where it becomes engageable with the extreme upper end of the intake valve controlling rod 6 when the longer end of t-he lever is raised by the action of the rod 26 when engaged by the lever 25.

Thus is it seen that, assuming there is pressure on the water supply pipe 5 and the valve 9 is closed upwardly against the seat 3 it will there remain by such pressure until the rod 6 lis forcibly depressed, and this takes place only when the lever 25 is raised to its extreme uppermost position. Immediately upon the depressing ofthe rod 6 which unseats the valve 9 Wetter will escape thereabouts into `to expedite operation of the mixer.

the tank, the weight of the rod 6 being sufficient to hold the valve 9 in its open position, While the float 10 and indicator arm will be raised or lowered by the action ol the Water within the tank, until its upward limit is reached, the same being controlled by its position on the rod as previously described.

Normally' the check valve 23 remains closed, both by the pressure of the water thereupon and the gravitating effect oi the operating lever 25, but instantly upon the raising of this lever the valve 23 will be raised and the contents of the tank rapidly discharged into the mixer; the nipple 2O and the size ot the nozzle being made comparativelylarge for quick emptying of .theank n a further raising of the lever 25 which also becomes necessary the intake Valve 9 is unseated and the tank again allowed to lill; the

. lever 25 and valve 23 automatically assuming l claim and desire to secure by Letters Paty ent, is

l. A tank of the class described comprising a receptacle, an intake valve, a discharge valve, an indicating lloat cooperatively 'connected with the intake valve, and single means for control of the discharge valve and optional control of the intake valve.
