Abstract

Abstract A drain tray apparatus (10) for collecting coolant and other fluids from an internal combustion engine including a pan (11) and tubular handle (12) is described. The pan includes a pump (15) which is used to receive coolant or other fluid from the pan and convey the fluid through the handle (12) to a hose (19) for recycling the fluid to a radiator for the engine or for disposing of the fluid down a drain. In the preferred form the pump is electrical so that it can be connected to a battery for starting the internal combustion engine.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 233 words
An improved drain tray apparatus adapted for collecting coolant or other liquids from an internal combustion engine or radiator and for recycling the liquid to the engine or radiator or disposing of the liquid which comprises: (a) a pan having a bottom and sides which is adapted to be positionable beneath the internal combustion engine or radiator so as to collect liquids which flow from the engine or radiator and having a low section in the bottom of the pan in which the liquid collects; (b) an elongate handle pivotably attached to the pan at one end of the handle and extending from the pan and with a pair of spaced apart hand grips so as to be usable in a standing position to move the pan beneath the internal combustion engine or radiator; (c) a pump mounted in the low section of the pan so as to produce a flow of the collected liquid from the pan into an inlet of the pump and through an outlet from the pump; (d) a conduit leading from the outlet of the pump between the handle and the grips and through a flexible hose extending away from one of the hand grips, wherein liquid is drained into the pan from the engine or radiator and then recycled into the engine or radiator through the conduit or disposed of through the conduit by activating the pump.
Claim 2
Dependent Claim 233 words
An improved drain tray apparatus adapted for collecting coolant or other liquids from an internal combustion engine or radiator and for recycling the liquid to the engine or radiator or disposing of the liquid which comprises: (a) a pan having a bottom and sides which is adapted to be positionable beneath the internal combustion engine or radiator so as to collect liquids which flow from the engine or radiator and having a low section in the bottom of the pan in which the liquid collects; (b) an elongate handle pivotably attached to the pan at one end of the handle and extending from the pan and with a pair of spaced apart hand grips so as to be usable in a standing position to move the pan beneath the internal combustion engine or radiator; (c) a pump mounted in the low section of the pan so as to produce a flow of the collected liquid from the pan into an inlet of the pump and through an outlet from the pump; (d) a conduit leading from the outlet of the pump between the handle and the grips and through a flexible hose extending away from one of the hand grips, wherein liquid is drained into the pan from the engine or radiator and then recycled into the engine or radiator through the conduit or disposed of through the conduit by activating the pump.
Claim 3
Dependent Claim 35 words
The drain tray apparatus of claim 1 wherein the pan has a height, width and length which allows the pan to be positioned beneath the radiator of a wheeled vehicle with the internal combustion engine.
Claim 4
Dependent Claim 67 words
The drain tray apparatus of claim 2 wherein the pan has a rectangular cross-section defined by spaced apart long sides defining the width of the pan to be positioned between the wheels of the vehicle and spaced apart short sides defining the length of the pan and wherein the elongate handle is pivotably attached adjacent a center portion of one of the long sides of the pan.
Claim 5
Dependent Claim 31 words
The drain tray apparatus of claim 3 wherein the low section of the pan is adjacent the handle and a center portion of one of the long sides of the pan.
Claim 6
Dependent Claim 50 words
The drain tray apparatus of claim 4 wherein the other of the long sides angles outward from the bottom of the pan away from the low section and wherein the bottom of the pan includes lateral sections of the bottom which angle downward into the low section of the bottom.
Claim 7
Dependent Claim 29 words
The drain tray apparatus of claim 1 wherein wheels are mounted beneath the bottom of the pan which allow the tray to be rolled into position using the handle.
Claim 8
Dependent Claim 70 words
The drain tray apparatus of claim 1 wherein the elongate handle is attached to one of the sides of the pan at the one end and comprises two pipes which are joined together in a center section, are spaced apart in a Y at one end which attaches to the pan and wherein each pipe has spaced apart sections which form the grips at an opposite end of the handle.
Claim 9
Dependent Claim 35 words
The drain pan apparatus of claim 7 wherein liquid flows through one of the pipes at one leg of the Y, through the center section and through the spaced apart section which forms one grip.
Claim 10
Dependent Claim 49 words
The drain pan apparatus of claim 8 wherein the pipe acts as part of the conduit for the liquid and wherein a first hose is connected from the pump outlet to the one leg of the Y of the pipe and a second hose leads from the one grip.
Claim 11
Dependent Claim 29 words
The drain tray apparatus of claim 1 wherein the pump is electrically powered and wherein a switch for the pump is provided adjacent the hand grip on the handle.
Claim 12
Dependent Claim 34 words
The drain tray apparatus of claim 1 wherein a spring means is provided between the pan and the handle so that the handle is pivoted into an upright rest position when not in use.
Claim 13
Dependent Claim 312 words
An improved tray apparatus adapted for collecting liquid coolant or other liquids from an internal combustion engine or radiator for recycling the liquid to the engine or disposing of the liquid which comprises: (a) a pan having a bottom and sides which is adapted to be positionable beneath the internal combustion engine or radiator so as to collect the liquid which flows from the engine or radiator and having a low section in the bottom of the pan in which the liquid collects; (b) an elongate handle pivotably attached to the pan and extending from the pan and with a pair of spaced apart grips so as to be usable in a standing position to move the pan beneath the internal combustion engine or radiator, wherein the elongate handle is attached to one of the sides of the pan and comprises two pipes which are joined together in a center section, are spaced apart in a Y at one end which attaches to the pan and which have spaced apart sections forming the grips at the opposite end; (c) an electrically powered pump mounted in the low section of the pan so as to produce a flow of the liquid from the pan into an inlet of the pump and through an outlet from the pump; (d) a first hose leading from the grip of one pipe of the handle; (e) a second hose between the outlet of the pump and the one of the pipes, wherein the liquid flows from the pan into the pump through the second hose into the one pipe and out the first hose and is recycled to the engine or radiator or disposed of through the first hose by electrically activating the pump; (f) wheels mounted beneath the bottom portion of the pan; and (g) an electrical switch mounted on the handle which activates the pump.
