9 Claims. 1 The present invention relates to a new and novel combination material mixing and filling machine.

The principal object of the invention is to provide a device for filling in underneath houses or buildings that are built close to the ground so as to prevent water from standing under these buildings.

Another object of the invention is to provide novel structure for satisfactorily mixing sand and water for eventual distribution underneath buildings.

A further object is to provide a machine which will both mix sand and Water and discharge the mixture for under building fill-in.

V A yet further object of this invention is to combine the functions of a positive displacement pump with that of a mixing mechanism.

These,ltogether with the various ancillary objects' of the invention which will later become apparent as the following description proceeds, are attained by this device, the preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figure 1 is an elevational view of the left side of the major portions of thepresent invention;

Figure 2 is a top plan view of the embodiment of the device shown in Figure '1;

Figure 3 is a vertical cross sectional view, taken along line 3--3 in Figure 2 showing the details of the mixing mechanism in greatest detail;

Figure 4 is an enlarged vertical sectional view of a portion of the device, taken along line 44 in Figure 3;

Figure 5 is an elevational view of the right side of the major portions of the space filling machine;

Figure 6 is a front elevational view of the preferred embodiment of the machine; and,

Figure 7 is a vertical cross sectional view of the device taken along line TI-J as in Figure 6. Referring now more particularly to the accompanying drawings, wherein like numerals designate similar parts throughout the various views, attention is directed first to Figures 1, 2, and '7. Reference numeral 10 generally designates an open'top hopper or vat having a front wall i2, rear wall 14, side walls l6 and I8, and bottom 20. Inner convergent falseside, rear and bottom walls 22 are providedwithin the vat. The vat is 'slidably mounted by means of bearing collars 24, attached to the rear wall 14, to a pair of posts 26 supported on the chassis of atr'ailer vehicle generally designated by reference numeral 28. A channel shaped'cross bar 30 is fastened on and extends between the upper ends of the posts 26. Pulleys 32 are journaled in the channel bar. A shaft 33 is journaled in bearings 36 on the rear of the vehicle and is provided with a ratchet handle 38. Another channel cross bar 40 is secured between the upper pair of bearing collars 26 and carries eye members 42. By means of suitable ropes 44 attached to the eye members 42 and the shaft 34 the entire vat is slidably raisable upon the posts 26 when it is desired to move the machine to a different location.

Referring now to Figures 2, 3, 4, and 7., it can be seen'that an arched wire mesh screen 46-is secured to the open top vat in its lower portions by means of bolts 48 and rubber or like yieldable mountingsfifl. 'A.vibrator assembly 52 comprising a vibrated member welded to the screen 46, includes a vibrating member comprising an eccentric 54 rotated through shaft linkage 56 and bevel gear 58. The vibrator assembly extends through the false rear wall 22 and is supported by the rear wall l4. Suitable driving means including a motor 60 for the vibrator assembly is carried by the chassis 28.

Secured immediately below the screen 46 is a spray bar 62 comprising a cylinder having closed ends and having a plurality of apertures therein. A pipe 64 connects the spray bar 62 with a valve 66 which is connected bymeans of flexible hose 68 to a water tank 'Hl having a closure 72 for a filler opening in the upper portion thereof. Beneath the water tank 10 is suitably mounted the axle 13 for a pair of ground-engaging wheels 14.

Rotatably journaled in the false side wall 22 of the vat It! is the shaft 16 of a screw conveyor 18. A sprocket wheel s rigidly fastened to the shaft 76, anda chain 82 passes around the sprocket wheel 80. The chain 82 is driven by chain drive means 84 connected to a motor 86 on the chassis 2B. The spiral blade 88 of the conveyor 78 is provided with apertures 90. Scoops 92 are formed by turning back tongues produced in forming the apertures 90. Other scoops 94 are welded upon the shaft 16.

. Adjacent the end of the conveyor '18 opposite that which carries the sprocket wheel the vat has a discharge aperture 96 in the rear false wall 22 in which nipple 98 is positioned. Secured to the nipple is a suction hose me which is connected to the inlet of a pump Hi2 driven by the motor 86; Valve I04 isp rovided in the suction hose line mo to control flow of fluid therethrough." An outlet hose N36 is attached to the pump I02.

The operation of the combined material mixing and fillingma'chine is as follows: Sand is dumped into the open top vat l and is piled upon the wire mesh screen 46. Water is gravity fed from the tank through the hose 68 and valve 66 through the pipe 64 into spray bar 62 where it is then discharged into the lower part of the vat Ill. The vibrator 52 is actuated by the power unit 60 and both vibrates the sand above the screen and sifts the sand through the screen into the conveyor 18. The conveyor 18 is rotated by the chains 82, the chain driving means 84, and the motor 8'6. The conveyor revolves so as to mix the sand and water, and at the same time, because of the pitch of its spiral blade positively displaces the mixture towards the discharge aperture 96. Additionally, the scoops 92 and 94 on the blades and the shaft of the auger respectively pick up water from the bottom of the .vat and throw the water above the wire mesh screen. The water contacts the sand and aided by the vibrator causes sand and water to fall down into the auger. The pump I02, driven by motor 86 sucks the mixture through the discharge aperture 9 through the suction hose I00 and pumps the mixture through the hose I66 to discharge it underneath a, house or building. The water is then drained off, and the sand remains thereby raising the level of the ground.

It can be easily understood that the material mixing and filling machine comprising a chassis having a water tank, a vibrator power unit, a

motor, a pump, may be easily transported as a trailer for an automotive vehicle, from one location to another after raising the vat' by simply turning the handle 38.

Since, from the foregoing, the construction and advantages of the combined material mixing and filling machine is readily apparent, further explanation is believed to be unnecessary;

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the exact construction illustrated and described, but all suitable modifications and equivalents may be resorted to which fall within the scope of the ppended claims.
