Filed July 10, 1957, Ser. No. 676,915

2 Claims. (Cl. 141-272) The present invention relates to an improved dispenser and to the combination of a water dispenser with a concrete mixer attachment for a tractor whereby the operator of the tractor can introduce the desired quantity of water into the drum of the concrete mixer in a most accurate and eicient manner. This invention relates to a concrete mixer attachment of the type disclosed in my prior pending application, Serial Number 667,381, led June 24, 1957.

The aforesaid pending application shows a concrete mixer attachment moun-ted on a tractor and wherein hydraulic means are provided for moving the mixing drum up and down, tilting the same, and rotating the drum about its axis. The concrete mixer attachment is constructed and arranged so that the operator of the tractor can load proper quantities of all the ingredients for mixing concrete, exclusive of water, into the drum. This can be accomplished by the operator without leaving the seat of the tractor.

The aforesaid concrete mixing attachment is also constructed and arranged so that it can be used in conjunction with the water dispenser described hereinafter for adding proper quantities of water into the mixing drum, and this operation can be carried out with the operator remaining on the tractor.

It is an object of the present invention to provide a dispenser adapted primarily but not exclusively for use with a concrete mixer, said dispenser being constructed and arranged so that it will discharge water into the drum of the mixer when said drum is moved against a valve opening mechanism of said dispenser.

It is another object of the present invention to provide a dispenser of the foregoing character Awhich has automatic means for regulating the inow of water into said dispenser.

It is still another object of the present invention to provide a dispenser of the foregoing character which is constructed and arranged so that inflow of water into the dispenser will be prevented while the dispenser discharges to said mixer so that a predetermined quantity of water is discharged.

Still another object of the present invention is to provide a dispenser of the foregoing character which has means for indicating the quantity of water in said dis penser.

It is still another object of the persent invention to provide a water dispenser for use with a concrete mixer, said dispenser having lwater inlet control means which can be adjusted to vary the quantity of water carried in said dispenser for discharge into said concrete mixer.

Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanying drawing forming a part of this speciiication wherein like reference characters designate corresponding parts in the several views.

In the drawing:

Figure l is a fragmentary side elevation vof a concrete mixer attachment operatively engaging a dispenser embodying one form of the present invention;

2,949,942 Patented Aug. 23, 1960 Figure 2 is an enlarged section of the dispenser illustrated in Figure 1; and

Figure 3 is an enlarged section of another dispenser embodying the present invention.

Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawing, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.

Referring now to the drawing, a more detailed description of the invention will 'be given. The embodiment of the invention shown in Figures l and 2 will be described first. Only a fragmentary portion of the concrete mixer attachment is illustrated, and reference is made to copending application, Serial Number 667,381, for a more complete showing.

In brief, the concrete mixer attachment 1li has a mixing drum 1'2 which is carried on shaft 14 for rotation therewith. The shaft 14 is rotated by gear 16 which is in mesh with drive gear 18 of the hydraulic motor 20. The shaft 14 is journaled in the frame member 22 from which extends the rigid arm 24. A transverse shaft 26 carries the frame member 22 between the two spaced side plates '28 (only one of which can be seen in Figure l) of the drum carrier 30. A hydraulic piston-andcylinder 32 is operatively connected between the arm 24 and the carrier 30 for pivoting the drum about the axis of the horizontally disposed Shaft 26. The carrier 30 is supported on the tower 34 for vertical movement by hydraulic means (not shown). Thus, it can be seen that the drum 12 can be raised and lowered on the tower 34, can be tilted about the axis of shaft 26, and can be rotated about its own 4axis by operation of motor 20.

When the concrete mixer attachment is mounted on a tractor, the operator can use the hydraulic system (not shown) for carrying out these movements, and as is explained in greater detail in the aforesaid application, Serial Number 667,381, the operator can load the drum by proper movement of the tractor and drum directly from piles of ingredients normally used in mixing concrete.

The present invention also allows the operator to move the tractor and drum to a water dispenser so that a proper amount of water can be added to the drum 12 for the concrete mixing operation. Such a dispenser is shown at 36 in Figure l.

The dispenser 36 has a receptacle 38 suspended from a support 40 in any suitable manner, such as by the cable 42. The dispenser 36 has valve means 44 at its lower end which is adapted to be engaged by the drum 12, as shown in Figure l, for transferring water from the receptacle 38 to the drum 12.

Referring to Figure 2, the parts of the dispenser 36 can be seen more clearly. The receptacle 38 has an outlet 46 and a nozzle 43 extending therefrom. A hole low valve member 50 seats in the outlet 46 for closing the same. An element or sleeve 52 surrounds said nozzle 48 in telescoping relation and has a spider 54 at its lower end. A rod 56 is connected between said valve member 50 and said spider 54 so that raising the sleeve 52 will cause lthe valve member 50 to be lifted from its seat, opening outlet 46.

The sleeve 52 is adapted to `be engaged and lifted by the drum 12. For this purpose a ange 58 projects laterally therefrom a suilicient distance to make it readily engageable by the upper edge of drum 12, as shown in Figure l. When it is desired to discharge the contents of receptacle 38 into drum i12, it is only necessary for the tractor 3 operator to move the drum 12 yunder receptacle 38, and thereafter raise the drum 12 suiciently high to cause valve member 50 to be raised from its seat. The water in receptacle 38 will then discharge through nozzle 48 intodrum12. .u

Y The dispenser 36 has a water inlet'duct 60..for reiilling the receptacle 38. Aconventi'onal float control mechanism 62 is operatively connected to the discharge end iof duct 60 to permit filling of receptacle 38 up to a predetermined level after which the iloat mechanism will close the duct 60 thereby preventing overflow of the lwater from receptacle 38.

In order to prevent water from owing into receptacle 38 while a measured quantity is being discharged into the mixing drum 12, a linkage is connected between valve member 50 Vand the float arm 64. This linkage includes a telescoping rod 66 and an associated sleeve 68 which are yoperatively connected respectively to the oat arm 64 and the valve member S0. The rod y66 and sleeve 68 are proportioned so that when the valve member 50 is lifted, the float arm 64 will be raised to its uppermost position effecting closing of inlet `duct 60. Also, the float arm 64 may have a limited hinge connection so that the oat 70 can descend with the water as shown in phantom, even though the opposite end of the arm is held in an elevated position by rod 66 and sleeve 68.

If desired, a flat spring 73 may be operatively positioned between the valve member 50 and float arm 64, as shown f in Figure 2, to act as a shock absorber when the valve member is lifted by the action of drum 12. Also, if desired, a water level indicating gage 73 may be positioned externally of receptacle 38 so that the operator can visually determine the amount of Water discharged into the drum 12. In the present embodiment, this is accomplished by the glass tubes 74 which are open at opposite ends and are in communication with the inner bottom of receptacle 38. Also, indicia 76 may extend adjacent raised, the hollow valve member 50a Will be raised allowing the Water to discharge through nozzle 48a into drum 12. The float control means 62a will control the level of the Water that enters through duct 60a. If it is desired to vary the setting of the oat control means 62a, this can be accomplished merely by releasing the turn screw 80 and sliding the duct 60a vertically, thereby raising or lowering the oat control means 62a.

Having thus described my invention, I claim:

1. In combination, a concrete mixer having means for raising and lowering a rotatable mixing drum with an open top, and a water dispenser for introducing a desired quantity of Water into said drum, said dispenser com prising a receptacle having an opening in its bottom and an `outlet nozzle in communication with said opening, a valve member seated in said opening for closing the same, a water inlet duct for discharging Water into said receptacle, Water level control means in said receptacle operatively connected with said duct for controlling the flow of water into said receptacle, a sleeve telescoped over the outer end of said nozzle and having a laterally extending flange on its inner end against which the top edge of said mixing drum can be raised for telescoping said sleeve further on said nozzle, and a rod operatively connected to said sleeve and said valve member for raising said valve member from its seat when the sleeve is telescoped further onto said nozzle, whereby water can then flow through said nozzle into said drum.

2. The combination of claim 1 wherein said valve member and said water level control means are operatively connected together so that when said valve member is raised from its seat no water can enter through said inlet the tubes to indicate the quantity of liquid being disy.
