Abstract

Abstract To mix, store and dispense pavement sealer material of the coal tar emulsion type a cylindrical tank is rotatably supported by rollers above a frame by means of shafts at either end and rollers intermediate the ends. The tank has a vented filler port to receive the material and a handle on one shaft turns the tank to mix the ingredients. To dispense, a pipe system is connected to a valve on the bottom of the tank, this system having an upper horizontal stretch extending outside the frame, a vertical leg down to the level of the area to be paved and an elongated lower horizontal stretch pivotted to the vertical stretch. The horizontal stretch has a valve so that the operator can control discharge. The lower stretch can be swung back and forth to cover the area.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 224 words
Apparatus for storing, mixing and dispensing pavement sealing material comprising a frame, a tank, said tank having a cylindrical body and conical ends, a plurality of rollers rotatably mounted on said frame for rotatably supporting said tank body, mechanical turning means for turning said tank, a filler tube and cap for filling said tank, said filler tube projecting radially from said tank body, a dispensing outlet nipple projecting radially from said tank body adjacent one end of said tank body, a valve member connected to said outlet nipple, said filler tube and dispensing outlet nipple being positioned relative to said rollers so that as said tank is revolved said rollers do not contact said filler tube, said cap, said outlet nipple, and said first valve member, the extent of radial projection of said tube and cap and of said outlet nipple and said first valve being sufficiently small so as not to contact said frame as said tank is revolved, and a piping system for detachable connection to an outlet of said first valve, said piping system comprising an upper horizontal pipe extending out beyond said frame and said one end of said tank body, a vertical pipe connected to said upper pipe, a lower horizontal pipe connected to said vertical pipe and a second valve at the outer end of said lower pipe.
Claim 2
Dependent Claim 224 words
Apparatus for storing, mixing and dispensing pavement sealing material comprising a frame, a tank, said tank having a cylindrical body and conical ends, a plurality of rollers rotatably mounted on said frame for rotatably supporting said tank body, mechanical turning means for turning said tank, a filler tube and cap for filling said tank, said filler tube projecting radially from said tank body, a dispensing outlet nipple projecting radially from said tank body adjacent one end of said tank body, a valve member connected to said outlet nipple, said filler tube and dispensing outlet nipple being positioned relative to said rollers so that as said tank is revolved said rollers do not contact said filler tube, said cap, said outlet nipple, and said first valve member, the extent of radial projection of said tube and cap and of said outlet nipple and said first valve being sufficiently small so as not to contact said frame as said tank is revolved, and a piping system for detachable connection to an outlet of said first valve, said piping system comprising an upper horizontal pipe extending out beyond said frame and said one end of said tank body, a vertical pipe connected to said upper pipe, a lower horizontal pipe connected to said vertical pipe and a second valve at the outer end of said lower pipe.
Claim 3
Dependent Claim 38 words
Apparatus according to claim 1 in which said tank body is formed with narrow, short slits and which further comprises baffle plates, each said plate located inside said tank and having its outer end filling one said slit.
Claim 4
Dependent Claim 64 words
Apparatus according to claim 1 in which said frame includes a pair of skids extending parallel to said tank adapted to fit on the body of a dump truck, whereby said truck body may be tilted to cause the contents of said tank to flow to one end and subsequently said frame may be hoisted from said truck body for storage of said apparatus.
