## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to concrete quantity counters for ready mix trucks and more particularly pertains to a new concrete-dispensing counter for ready mix trucks for measuring the volume of concrete discharged by a ready mix concrete truck.
2. Description of the Prior Art
The use of concrete quantity counters for ready mix trucks is known in the prior art. More specifically, concrete quantity counters for ready mix trucks heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. No. 4,544,275; U.S. Pat. No. 3,927,800; U.S. Pat. No. 4,239,128; U.S. Pat. No. 3,565,288; U.S. Pat. No. 5,622,163; U.S. Pat. No. 4,387,299; and U.S. Pat. No. 4,096,383.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new concrete-dispensing counter for ready mix trucks. The inventive device includes a prime mover having a drum being rotatably mounted thereupon and also having a discharge chute through which cement is dispensed from the drum; and also includes a light emitting/reflecting assembly being mounted to the prime mover and including a plurality of light reflectors being spacedly attached about an exterior of the drum opposite to the discharge chute and also including a light-emitting member and a light-detecting member being mounted to the prime mover; and further includes a microprocessor being connected to the light-emitting and the light-detecting members; and also includes a concrete-dispensing sensor being attached to the discharge chute and to the light emitting/reflecting assembly and to the microprocessor for actuating the light emitting/reflecting assembly and the microprocessor.
In these respects, the concrete-dispensing counter for ready mix trucks according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of measuring the volume of concrete discharged by a ready mix concrete truck.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 3 thereof, a new concrete-dispensing counter for ready mix trucks embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 3, the concrete-dispensing counter for ready mix trucks 10 generally comprises a prime mover 11 having a drum 12 being rotatably and conventionally mounted thereupon and also having a discharge chute 13 through which cement is dispensed from the drum 12. A light emitting/reflecting assembly is conventionally mounted to the prime mover 11 and includes a plurality of plate-like light reflectors 14 being spacedly and conventionally attached about an exterior of the drum 12 opposite to the discharge chute 13, and also includes a light-emitting member 15 and a light-detecting member 16 being conventionally mounted to the prime mover 11.
A microprocessor 17 is conventionally connected to the light-emitting 15 and the light-detecting members 16. The microprocessor 17 includes a housing 18. The light-emitting and light-detecting members 15, 16 are conventionally disposed in the housing 18 and are directed toward the light reflectors 14. The light-detecting member 16 is a photo-sensor. The housing 18 is conventionally mounted upon a casing 20 disposed about a motor which drives the drum 12. A concrete-dispensing sensor 21 such as a conventional optical, mechanical or conductive sensor is conventionally attached to the discharge chute 13 and to the light emitting/reflecting assembly and to the microprocessor 17 with wires (not shown) for actuating the light emitting/reflecting assembly and the microprocessor 17. A conventional display counter 19 is conventionally mounted upon the prime mover 11 and is conventionally connected to the microprocessor 17 for counting quarter turns of the drum 12.
In use, as cement or concrete is being dispensed from the drum 12 through the discharge chute 13, the concrete-dispensing sensor 21 actuates the microprocessor 17 and the light-emitting and light-detecting members 15,16; whereupon the microprocessor 17 records the number of quarter turns of the drum 12 and the number is displayed on the display counter 19 so that the user can keep an accurate record of the number of yards of concrete or cement is being dispensed from the drum 12.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
