Abstract
Abstract A portable blower device for picking up debris in which minerals such as gold may be deposited in cracks and crevices and the like. A blower assembly is mounted with a harness for carrying on the back of the user to create a vacuum for pulling air through a flexible tube connecting with a container. Leading from the collector container is a second hose connecting with an elongated hollow tubular member which can be inserted into cracks and crevices for drawing out debris and minerals for deposit in the collector. The device is compact and easily portable and, by insertion of the collector into the harness, can be hand-carried as a unit.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
Apparatus for collecting soil and rocks from remote crevices and the like comprising: a portable self-powered blower assembly having a first exhaust port and first intake port; a collector separated from said blower assembly and comprising a closed container having an intake opening and an exhaust opening; a harness for mounting said blower on the user's back; a first flexible hollow tube connecting the intake port of said blower with the exhaust opening of the collector; a rigid tubular elongated hollow member having one end suitable for probing remote crevices and a second end adapted for attachment to a flexible tube; a second flexible hollow tube connecting the intake opening of the collector with the tubular member second end whereby the blower assembly can be energized to create a vacuum air flow inward through the rigid member for picking up soil and rocks; second and third intake ports connecting with said blower assembly with a third flexible tube connected therebetween; and a flow-regulating intake port connecting with said third flexible tube to regulate the flow of air through said blower assembly.
Claim 2
Dependent Claim
181 words
Apparatus for collecting soil and rocks from remote crevices and the like comprising: a portable self-powered blower assembly having a first exhaust port and first intake port; a collector separated from said blower assembly and comprising a closed container having an intake opening and an exhaust opening; a harness for mounting said blower on the user's back; a first flexible hollow tube connecting the intake port of said blower with the exhaust opening of the collector; a rigid tubular elongated hollow member having one end suitable for probing remote crevices and a second end adapted for attachment to a flexible tube; a second flexible hollow tube connecting the intake opening of the collector with the tubular member second end whereby the blower assembly can be energized to create a vacuum air flow inward through the rigid member for picking up soil and rocks; second and third intake ports connecting with said blower assembly with a third flexible tube connected therebetween; and a flow-regulating intake port connecting with said third flexible tube to regulate the flow of air through said blower assembly.
Claim 3
Dependent Claim
28 words
Apparatus as defined in claim 1 wherein said first exhaust port includes means for connecting a fourth flexible tube to provide outward blowing air through said fourth tube.
Claim 4
Dependent Claim
169 words
Apparatus for collecting soil and rocks from remote crevices and the like comprising: a portable self-powered blower assembly having a first exhaust port and first intake port; a collector separated from said blower assembly and comprising a closed container having an intake opening and an exhaust opening; a harness for mounting said blower on the user's back and wherein said harness can be placed around said collector to mount the collector on said blower and provide a compact and easily portable apparatus; a first flexible hollow tube connecting the intake port of said blower with the exhaust opening of the collector; a rigid tubular elongated hollow member having one end suitable for probing remote crevices and a second end adapted for attachment to a flexible tube; and a second flexible hollow tube connecting the intake opening of the collector with the tubular member second end whereby the blower assembly can be energized to create a vacuum air flow inward through the rigid member for picking up soil and rocks.
Claim 5
Dependent Claim
169 words
Apparatus for collecting soil and rocks from remote crevices and the like comprising: a portable self-powered blower assembly having a first exhaust port and first intake port; a collector separated from said blower assembly and comprising a closed container having an intake opening and an exhaust opening; a harness for mounting said blower on the user's back and wherein said harness can be placed around said collector to mount the collector on said blower and provide a compact and easily portable apparatus; a first flexible hollow tube connecting the intake port of said blower with the exhaust opening of the collector; a rigid tubular elongated hollow member having one end suitable for probing remote crevices and a second end adapted for attachment to a flexible tube; and a second flexible hollow tube connecting the intake opening of the collector with the tubular member second end whereby the blower assembly can be energized to create a vacuum air flow inward through the rigid member for picking up soil and rocks.
Claim 6
Dependent Claim
178 words
Apparatus for collecting soil and rocks from remote crevices and and the like comprising: a portable self-powered blower assembly having a first exhaust port and first intake port; a collector separated from said blower assembly and comprising a closed container having an intake opening and an exhaust opening; a harness for mounting said blower on the user's back; a first flexible hollow tube connecting the intake port of said blower with the exhaust opening of the collector; a rigid tubular elongated hollow member having one end suitable for probing remote crevices and a second end adapted for attachment to a flexible tube; a second flexible hollow tube connecting the intake opening of the collector with the tubular member second end whereby the blower assembly can be energized and to create a vacuum air flow inward through the rigid member for picking up soil and rocks and means to removably connect said collector to said blower assembly so both may be carried as a unit including a hanger for hanging the collector from the bottom of the blower assembly.
