Abstract
Abstract A dumping system wherein a pneumatic bag pivotally lifts a bed and the bag expansion results from use of vehicle exhaust. In a preferred form, a dumping unit is adapted to be placed on and removed from an existing truck bed to provide a dumping vehicle and in another preferred form the dumping bed pivot can be raised and lowered whereby items can be slid into or out of the dumping bed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
121 words
In combination, a truck having a fixed bed thereon and an engine exhaust pipe; a dumping unit comprising a platform resting on the fixed bed; a load bed including a bottom and upstanding side walls and an end wall interconnecting said side walls; hinge means interconnecting the platform and the load bed at an end opposite the end wall; a collapsible gas impervious bag positioned between the platform and the load bed; hose means extending from the interior of the bag outwardly thereof and connected to an exhaust pipe of the truck; and means for stabilizing the load bed as it pivots about the hinge means, said means also holding the bag in position between the platform and the load bed.
Claim 2
Dependent Claim
121 words
In combination, a truck having a fixed bed thereon and an engine exhaust pipe; a dumping unit comprising a platform resting on the fixed bed; a load bed including a bottom and upstanding side walls and an end wall interconnecting said side walls; hinge means interconnecting the platform and the load bed at an end opposite the end wall; a collapsible gas impervious bag positioned between the platform and the load bed; hose means extending from the interior of the bag outwardly thereof and connected to an exhaust pipe of the truck; and means for stabilizing the load bed as it pivots about the hinge means, said means also holding the bag in position between the platform and the load bed.
Claim 3
Dependent Claim
40 words
The combination of claim 1, further including a convertor pump connected between the hose means and the vehicle exhaust pipe, whereby the exhaust through the pipe drives the convertor pump to supply fresh air to the interior of the bag.
Claim 4
Dependent Claim
62 words
The combination of claim 1, wherein the means for stabilizing the load bed includes a pair of crossed rods interconnecting the platform and the load bed; means journaling one end of each rod; a slotted slideway at the other end of the rod; and roller means carried by each of said rods and arranged to travel in a slot of a slideway.
Claim 5
Dependent Claim
85 words
A dumping system comprising a truck; a load bed thereon; an expansible gas impervious bag beneath the load bed; a loading dock having a pivotable platform section; an expansible gas impervious bag beneath the platform section; means for releasably coupling each of said bags to the exhaust pipe of the truck; and means for moving one end of the load bed up to the top of the raised pivotable platform section and for thereafter holding said one end as the load bed is pivoted therearound.
Claim 6
Dependent Claim
85 words
A dumping system comprising a truck; a load bed thereon; an expansible gas impervious bag beneath the load bed; a loading dock having a pivotable platform section; an expansible gas impervious bag beneath the platform section; means for releasably coupling each of said bags to the exhaust pipe of the truck; and means for moving one end of the load bed up to the top of the raised pivotable platform section and for thereafter holding said one end as the load bed is pivoted therearound.
Claim 7
Dependent Claim
42 words
A dumping system as in claim 4, further including a convertor pump connected between the hose means and the vehicle exhaust pipe, whereby the exhaust through the pipe drives the convertor pump to supply fresh air to the interior of the bag.
Claim 8
Dependent Claim
62 words
A dumping system as in claim 4, wherein the truck has a fixed bed thereon; the load bed is positioned above a platform resting on the fixed bed and is connected to the platform by pins projecting into vertically slotted posts that extend upwardly from the platform; and the expansible, gas impervious bag beneath the load bed is positioned on the platform.
Claim 9
Dependent Claim
39 words
A dumping system as in claim 6, wherein means are provided for holding the expansible, gas impervious bags in place and for stabilizing the pivotable platform section of the loading dock and the load bed as they are moved.
Claim 10
Dependent Claim
121 words
A dumping unit comprising a platform having a front, rear and sides; a load bed having a front, rear and sides; hinge means interconnecting the rear of the platform and the rear of the load bed; a collapsible, gas impervious bag positioned between the platform and the load bed; stabilizing means interconnecting the sides of the platform with the sides of the load bed, said means being movable to allow for separation of the load bed from the platform and serving as retaining means to hold the bag between the platform and the load bed; and hose means extending from the interior of the bag outwardly thereof, whereby said hose means can be connected to a source of gas under pressure.
Claim 11
Dependent Claim
121 words
A dumping unit comprising a platform having a front, rear and sides; a load bed having a front, rear and sides; hinge means interconnecting the rear of the platform and the rear of the load bed; a collapsible, gas impervious bag positioned between the platform and the load bed; stabilizing means interconnecting the sides of the platform with the sides of the load bed, said means being movable to allow for separation of the load bed from the platform and serving as retaining means to hold the bag between the platform and the load bed; and hose means extending from the interior of the bag outwardly thereof, whereby said hose means can be connected to a source of gas under pressure.
Claim 12
Dependent Claim
63 words
A dumping unit as in claim 7, wherein the means for stabilizing the unit includes a pair of crossed rods interconnecting the platform and the load bed; meAns journaling one end of each rod; a slotted slideway at the other end of the rod; and roller means carried by each of said rods and arranged to travel in a slot of a slideway.
Claim 13
Dependent Claim
98 words
A dumping unit comprising a platform; a load bed positioned above the platform means pivotally connecting the load bed to rotate at one end thereof above the platform; a collapsible, gas impervious bag positioned between the platform and the load bed; hose means extending from the interior of the bag outwardly thereof, whereby said hose means can be connected to a vehicle exhaust pipe; and a convertor pump connected between the hose means and the vehicle exhaust pipe, whereby the exhaust through the pipe drives the convertor pump to supply fresh air to the interior of the bag.
Claim 14
Dependent Claim
98 words
A dumping unit comprising a platform; a load bed positioned above the platform means pivotally connecting the load bed to rotate at one end thereof above the platform; a collapsible, gas impervious bag positioned between the platform and the load bed; hose means extending from the interior of the bag outwardly thereof, whereby said hose means can be connected to a vehicle exhaust pipe; and a convertor pump connected between the hose means and the vehicle exhaust pipe, whereby the exhaust through the pipe drives the convertor pump to supply fresh air to the interior of the bag.
