Patented June 2, 1931 UNITED STATES ALBERT F. TEICHMAN AND JOHN W. THEE, OF CINCINNATI, OHIO WATER CONTROL DEVICE Application filed March 2,

This invention relates to a water control device and has for an object the provision of a device whereby an accurately measured quantity of water may be automatically delivered from a supply pipe to a tank or container and retained therein for subsequent rapid discharge into any suitable receptacle such mixer.

An object of the invention is to provide a water control device which may be conveniently mounted on practically any approved type of concrete mixer and one which is adapted for automatic co-operation with such mixers to the end that a predetermined quantity of water is always available for automatic discharge into the mixer when cement and aggregate material from a loading hopper are discharged into the mixer.

Another object is to provide means for the purposes stated'which so facilitates the operation of properly mixing cement and aggregate material with the proper quantity of water as to encourage the use of the automatic mechanism by the operator.

Another object isfto provide a device of (his kind with means vwhereby intentional mis-use of the'device may be rendered difficult and readily observed by a supervisor.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fig. 1 is a fragmental side elevational view of a concrete mixer having mounted thereon a water control device of the invention.

Fig. 2 is a rear elevational view of a device of the invention.`

Fig. 3 is a view taken online 3-3 of Fig. 2.

Fig. 4 is a side elevational view of a structure forming a detail of the invention and serving to synchronize and render automatic the operation of the water control device with a concrete mixer.

The device of the invention, independent of a mixer or other mechanism to which it may be attached, comprises a suitable supporting frame which may be constructed of suitable spaced angle or channel members 11 from which a bracket 0r upright structure 50 12 extends. The uprights 12 may carry suit- 1928. Serial N0. 258,652.

able cross members 13. F ulcrums or roller bearings 14 are mounted upon upwardly projecting portions ot members 12 pivotally supporting a beam structure. The beam structure comprises a bar 15 having a transverse 5 member 16 from the opposite ends of which extend arms 17. The beam structure comprising the members 15, 16 and 17 will hereafter be referred to as beam 18 upon which is adjustably mounted a weight 19. At the ends of the arms 17 of beam 18 are depending links 20 which support a tank member 21. The arms 17 are pivotally mounted on the roller bearings 14 intermediate their opposite ends, the weight 19 normally retaining the 65 tank in a raised position. The tank 21 is preferably provided with an inclined bottom 22 having an apertured discharge tube v23 secured thereto and supplied upon its upper face with a suitable gasket member 24. 7u Interiorly of the tank 21 are provided lugs 25 through which extend pintles 26 for hingedly mounting a` valve 27. Above theV discharge tube or aperture 23 and across the top of the tank are suitable transverse members 28 to the underside of which is secured a suitable bearing S29-for the end of a rod 3() which also finds a 4bearing at 3.1 in an end wall of the tank 21. l

Rigidly secured to the rod 30 is an arm 30 32 the end of which has pivotally attached to it a. link 33. The link 33 has a pivotalconnection at 34 with the valve 27. Oscillation of rod 30 b means of crank handle 35 serves t-o lift and lower the hingedly mounted valve 35 27 for opening and closing discharge pipe 23.

A water supply pipe 36 is fixedly mounted adjacent the tank 21 and has a valve controlled spout 37 overhanging the tank. The valve 38 may be of the whistle valve type, 90 provided with a weighted lever 39 with a roller 40 on its free end and adapted to normally retain the valve in closed position when lever 39 is in av lowered and unsupported position, as shown in Fig. 3. A cam 41 is xedly mounted on rod 3() in such position that it may operate, upon movement of the rod about its axis, to abut the roller 40 and raise lever 39 to open valve 38.

However it will be noted that. because of the suspension of the tank 21 upon beam 18,

the tank will. rise and descend bodily accordingly as the weight 19 overbalances the empty tank, lor the tank, filled with water from` nozzle 37 overbalances the weight. The rod 30 journalled in the tank moves bodily with with valve 38 open. From the foregoing it will be noted when the tank is filled withv water sufficiently to overcome the weight 19 in its adjusted p posit-ion, an accurately weighed quantity of water is in theV tank and the supply shut off by the descending movement of the tank.

The filled tank now iemains ready to r be almost instantly discharged upon opening of valve 27 by turning rod 30 about its anis by means of handle crank (see'Fig. 3).

When the tank is thus emptied the weight 19 again raises the tank and rod 30, but, so long as handle 35 remains in position` to hold valve 27 open, cam 4,1 cannot touch roller 40 toV raise valve lever Y 39. Movement of handle crank 35 inthe opposite direction completely cl-osesrvalve 27and then opens valve 38 by means of the cam 41. The structure thus far described is of general application and may be used to advantage by manual operation of lhandle crank 35 in many Y instances.

The lsimple mechanism shown in Fig.V 4 may be associated with the device just described and the combined structures applied 'i to a concrete mixer so that automatic operation ofthe device is attained through the agency of the loading hopper as it raises to discharge cement and aggregate material into the mixer and is low-eredto receive a new batch of said materials.

As shown in' Fig. 4 a pivot bar 42 having rigidly secured toit an arm 43-is provided with a pivotal bearing at 44 upon cross member 13. This bearing is substantially zin' alignment with the axis of rod 30fand is slightly above it. VArm 43 lies directly over Y the handle crank'35 to which Vit has an anti- :sol

friction .connection through yoke 45 rigidly attach-ed to arm 43. The yoke carries a pair of spaced rollers 46 between which the handle crank 35 extends so that when the arm ,and handle crank are rotated about their several spaced axes the connection between the two members is retained and the movement of the handle crank 35 relative to the yoke 45 takes place with aminimum of friction. From the foregoing it will be apparent that by impartingtilting movement to pivot bar 42 about its fulcruni or pivotal mounting 44 the handle crank 35 may be manipulated. As will be noted in Figs. 1 and 4 the pivot bar 42 has a counter-weight 47 which normally drops to adjustable stop 48 so as to 'dispose the arm 43insubstantially a-vertical posi-V v tion. In this positionthe arm 43 holds the the water supply valve 38. It should beV noted that in this position the valve 27 is tightly closed. As shown in Figs. 1 and 5 a shaft 480 is mounted in spaced bearings 49 carried by vupright members 50 which form part of the supporting structure upon which loading hopper 51 is mounted. The shaft 480 carries a short rocker arm 52 having a roller 53 thereon adapted to be engaged by a plate 54 carried by. loading hopper 51 as it moves about its pivotal mounting at 55. The loading hopper in the present embodiment is power actuated in its raising and lowering movements and is controlled by means of a throttle lever or clutch lever not shown. The shaft 480 also has a long rocker arm 56 rotatable therewith by means of a pin 62 normally disposed in a slot in sleeve 64 which is integral with arm 56 so that whenthe vhopper 51 raises and moves short rockerV armVV 52 through an arc, the long rocker arm 56 is lowered. An adjustable*connecting link 57 having a suitable clevis 58 at each end which are pivotally mounted to the longY rocker arm 56 and the ,end of pivot bar 42 respectively, serves to automatically move the arm 43 and crank handle 35 whenever the hopper 51 is raised to discharge into the mixer 59; When discharge tube 23 of tank 21, while its oppositeend is inserted in the rotatingmixer drum 59 to direct the flow in any desired manner within the drum; l f

This automatic actuation of the tank may be' rendered inoperative through the mechanisin shown in Fig. 5 wherein handle 61V carrying pin 62 is pushed forwardly against the resistance of spring 63 so that the pin' 62 moves out of the slot in sleevev 64 and into the connecting slot in sleeve The handle 61 is then rotated to the position shown in dotted lines in Fig. 4and the short rocker arm 52 is moved up and .outrof the pat-h of the hopper 51. It should be noted. that the end of handle crank 35 extends beyond the arm 43 Vso that when the automatic operation isthrown out as explained, it may be manually?l controlled by the handle crank The operation of the device is as follows. Assuming that the water supply pipe 3,6 is connected Ywith a suitable source of water supply and the part-s are in position shown in Fig. 3 wherein the tank 21 has discharged its contents into the spout 60. With the automatic feature in operation, theloading hopper 51 is in a iraised position at such iinevto discharge cement and aggregate maiin izo

teria-ls into the mixer' 59. As soon as the tank has discharged its contents the weight 19 will drop, raising the tank bodily. It should be noted that at this time the lever 35 is still in the position shown in Fig. 3 wherefore rod 30 and cam 41 are also in the position shown in that view. The valve 27 also remains open. At this time the weighted end of the pivot bar 42 is raised, being held in that position by the action oi the hopper 51 through the short and long rocker arms and connecting link 57. IVhen the hopper is lowered, Weight 1-7 moves pivot bar 112 about its fulcrum 44 raising long rocker arm 56 by means of the connecting link 57. At this time the arm /13 moves with the pivot bar 42 and turns the rod 30 about its axis by means of the handle crank.

It should be noted that when the tank is discharged it is in an elevated position because of the counterbalance 19; therefore relative longitudinal movement takes place between the arm 43 and handle crank IVhen the handle crank 35 is brought to vertical position it will be noted that the valve 27 will close due to the action of arm 32 and link 33 and immediately following the closing, the cam 41 will be moved about its axis to encounter the roller 40 to raise lever 39 and to open water valve 38. Tater then flows through the pipe 36 into the tank 21 until the tank contains a sutficient quantit-y (by weight) of water to tip the beam structure 18 about its pivotal mount-ing at 14 so that the tank descends bodily to encounter a stop and suticiently to remove the cam 41 from lever 39. Thus the water supply is automatically shut olf.

A suit-able seal, padlock, or the like (not shown) may be employed to prevent accidental or intentional movement o'l" weight 19 from its predetermined adjustment on the graduated lnember 15 of beam 18. The markings or graduations 15() may indicate net units of weight of water in the tank, when tank and weight 19 attain a position of equilibrium. In this way the device may be adjusted by a superviser or responsible employee. The Water ratio theory, with which those versed in the art are thoroughly conversa-nt, may be put into actual practice without necessitating the employment of skilled labor.
