' Usage MPh/lFEE Zaad@ Patented Apr. 7, 1931 UNITED STATI-gsA l OSCAR W. IPHIFER, F TOPEKA, KANSAS CONCRETE HOPPER VALVE MEASURING DEVICE l V Application illedJ'uly 12, 1927. Serial No. 205,264.

My invention relates to a concrete hopper valve measuring device.

The object of my invention is to provide a hopper having a rockable partition and a choke member to control the flow of concrete.

A further object of my invention is to provide a valve measuring means for the lower end of the hopper. a

A still further object of my invention is to 1.0 provide a valve measuring means having a cutoff for the measurer and a cutoff for the hopper when the measuring device is drawn forward to discharge its contents into a mould or form.

These and other objects will hereinafter be more fully explained.

Referring to the drawing in which like characters apply to like parts in the different vlews:

2o Fig. 1 is a perspective view of the hopper and valves with parts removed for the purpose of illustration. A

v Fig. 2 is a side view of one of the catches for the partition' plate.

Fig. 3 is a plan view of the detent shown in Flg. 2.

Fig. 4 is an end view of the choke plate showing the adjusting screw.

A container 1, open at the top and bottom is slidably positioned between a plate 2 and the lower end of a hopper 3. A cutoff board 4 is integral with the upper portion of the container and slidably engages with the guides 4 as shown. This board serves to close the bottom of the hopper when the container is moved over the aperture at Al in the plate 2 to discharge its contents. n

Arms 5 are pivotally connected between the levers 6 and the container 1. When the levers 6 are rotated in the direction of the arrow at B in Fig. 1 the container moves over the aperture A and the cutoif board 4 closes the bottom of the hopper. The container may be divided by a partition placed as indicated by the dotted lines at C inFig. 1 when only half is needed. (5

A choke plate 7 is hinged across and near the lower'end of the hopper 3. 'A screw Sis arranged to adjust the position of the choke plate as illustrated in Fig. -4. The purpose the said hinged gate in continuous contact o f the choke plate is to reduce the discharge opening of the hopper as desired.

A partition plate 9 is pivotally connected at its lower end to near the mouth of the hopper at D. This plate fits rather closely at its edges to the sides of the hopper and may be held in a vertical position by catches 9 fastened to the front and rear sides of the hopper as at E.

These catches protrude through the aper- 6o tures 10 in the sides of the hopper and areV fastened to the said sides by the spring members 11.

When the catches 9 are pulled back as indicated by the arrow at F in Fig. 2, the partition plate may be positioned to either Vside of the hopper as indicated by the dotted lines G in Fig. 1. Such a position is used when 'a partition is placed in the container 1 at C and only one side of the said container is to be filled with concrete. The lower portion of the plate 9 is removed adjacent the choke plate 7 to allow free movement of both plates. A V-shaped flap l2 is hinged to the plate 9 at this'point and functions to close the opening between the said plates. v By proper positioning of the

plates

7 and 9 the discharge of concrete from the hopper into the container may be controlled as desired.

Such modifications may be employed as lie within the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is: 1. In a dispensing hopper for concrete, a hopper having a spout rectangular vin cross section, hinged gates positionedv at the lower extremity of the hopper, one of the hinged gates being pivoted at the center and eXtreme bottom of the spout and rockable to the sides thereof and means to position :he said gate in the center of the spout, a hinged flap on with a second hinged gate, the sec'nd hinged gate being positioned somewhat above the discharge point of the spout and ad]ustable to :the first said hinged gate and functioning to vary the discharge aperture of theuspout,

means to position the second hinged gate substantially as shown.

2. In a. dispensing hopper for concrete, in combination a hopper, valves in the hopper, said valves comprising a vertical plate pivotally connected at its lower part to near the discharge point of the hopper, a choke plate pivotally connected to the side of the hopper at right angles to the vertical plate and a container slidably positioned to the bottom of the hopper, a cut oi board integral with the said container and functioning to close the h opper when the said container 1s moved.

In testimony 'whereof I aix my signature.
