Abstract

The invention appeals to contractors, technical services, farmers, nurserymen and foresters who need small, mobile, vandalproof depots for motor-driven machinery. The combination tank, (Fig. 1 and 2), is a traditional fuel tank compartment (1) with a tool compartment (2) consisting of pull-out drawers (3) and shelves (4) for storing tools, spare parts and lubricants. The tool compartment (2) is closed by means of an end door (5) with a handle (6) and locked by means of a padlock (7) kept in an oval niche (8), which prevents cutting. The filling, venting and tapping section (9) of the fuel tank is located in the top of the tank under a bell-shaped cover (10) which can be opened and which is locked from inside the tool compartment (2) by means of a bar (11). The frame (12) around the section (9) conducts fuel spills to a trap (13) in the bottom of the tool compartment (2). The trap (13) is covered by a perforated plate. The combination tank is positioned on runners (14) and is lifted by means of eyes (15).

Description

COMBINATION STORAGE TANK FOR FUEL AND TOOLS

The invention concerns a mobile fuel tank to be used within trades with shifting work places applying various motor driven working machines.

The standpoint of today's technique is that mobile fuel vessels are solely used for storage of motor gas oil, here a shell and two end plates form the fuel tank itself and the necessary sockets are placed upwards.

However, there is a Swedish patent No. 7909390-2, descr¬ ibing a mobile tank with a store room limited by several fuel rooms built together in such a way that a lift at just one point (state of equilibrium) is possible.

Further, the use of containers is known for storing of various tools and drums containing various lubricants.

Th. SP mobile fuel tanks can be provided with manual or electrical pumps for transfer of fuel, or the can be delivered with sockets for self-priming from the working machine's own pump.

The filling sockets are protected from theft by fixing the function of covers and pumps with a padlock or by building a small locked cabinet above the pump itself.

Further, there have not been taken any special precau- tions to reduce or accumulate escape from the vessel during filling and operation with a leaky pump.

The special technique used here and the very invention is the introduction of a compact shelf-system in a special store room. This makes it possible to store many secondary auxiliaries in good condition. Access to com¬ bination tank filling sockets and the store room shelves is controlled with lockable doors locked with a padlock. These doors are designed so that even very gross destru¬ ction of property will not make access to the content of the tank. Further, on the outside the tank appears as a standard storage tank and at first sight it is not poss- ible to note any difference.

Technically, with this new invention you obtain a com¬ pact, strong and at the same time a functional store container for various secondary auxiliaries which can be stored under safe conditions.

This tank is protected against theft, is environment- friendly and can be used at work places using diesel- dreven machines.

The new means used with point of departure in the known technique are as follows:

1. A built-in compact shelf system for storing of various lubricants, tools etc.

2. Environment-friendly design of the combination tank ensuring collection of waste from the combi¬ nation tank.

3. Protection against theft and destruction of property - attained through casing vital parts behind locked doors.

Point 1

Incorporating of a drawer system at one end of the tank makes appropriate storing of various tools possible. Application of extensible drawers maker; erionomic cor¬ rect handling of heavy things such a oil drums etc, possible. Main features by which the purpose of the invention is achieved

(Please see fig. 5 and 6)

Room I limited by end cover (2) and bulkhead (3) , shell (14) and 16 pipes (1) . These pipes, welded onto end cover (2) and led through bulkhead (3) increase the strenght of the fuel section in room I and the whole combination tank. At the same they act as guide pipes for Room II' s shelf system.

In room II there is a shelf system (4a-h) consisting of 5 extensible drawers and 3 extensible shelves for stor¬ ing of various auxiliaries. Each of the extensible drawers and shelfes is built-up on two horizontal pipes (4) controlled by a fixed pipe (1) with a larger diam¬ eter fixed to bulkhead (2) and (3) . A fixed stop (20 - please see Fig. 5 & 6) prevents the drawer from being drawn out of its suspension. The fixed pipe absorbs the w ig t t the drawers.

On the 3 extensible shelves 3 quarter oil drums are placed for storing of motor oil, gear oil and hydraulic oil. On the remaining 2 drawers waste oil containers, sprinkler liquid etc. anti-freezing liquid if any are placed.

On 3 of the shelves the following is stored: tools, grease gun, grease cartridges, litre, filler funnel, wire cloth, gloves, wearing parts etc. Room II is closed by means of a door (12) . On the inside of the door the following is placed: a spade, a broom and a 5 kilo ham¬ mer (please see fig. 8)

Point 2

The features by which the purpose of the invention is obtained.

(Please see fig. 7) In room II under the lowest drawer there is a spill-box for oil waste and it is covered with a perforated plate (19) which can be removed when box (13) has to be emptied. The box can only be emptied when door (12) is opened, (please see fig. 9) .

Spillage from the top of the tank in connection with filling and filling up of tanks is accumulated by a 40 mm high collar (23) preventing the oil from running outside the tank and leads it down into the spill box (13) .

The placing of both oils and liquids in room II prevents pollution at the work place.

Point 3

The features by which the purpose of the invention is obtained.

(Please see fig. 9) One of the main purposes of this invention is to secure it against theft. Today it is common by means of a bolt cutter to obtain access to filling sockets for motor fuel. This invention is protected against theft by plac¬ ing vital parts of the tank (pump, filling sockets, bottom drain valves etc.) behind lockable doors prevent¬ ing unintentional access.

To arrive at the internal room II of the tank, door (12) has to be opened. Door (12) is round and finished with a ring of strong pipe (24) . The pipe ring (24) has been welded together with a pipe socket (25) so that it forms part of an hinge.

The door (12) is mounted by welding onto the ring (24) and enforced by flat iron. The finished door (12) is hinged to the shell (14) by means of two lugs and a through-going bolt (27) is fixed and is then welded onto the lugs. The strong pipe ring is encased by closing a angle frame (28) which is welded onto the shell (14) . The door is opened by a handle (29) and secured by a padlock (17) placed in a sunk oval niche. This niche placing of the padlock prevents cutting with a bolt cutter. It is important that the lock pin length is adapted to the bottom of the niche (18) so that the door (12) with a little distance is positioned to the angle frame (28) so the access to room II will become diffi- cult even though the hinge is removed.

When the door is open, there is access to room II. To have access to the filling sockets at the top of the combination tank the lock pin (21) has to be drawn out of the lock at the "bell" (8) . By drawing out the pin, the "bell" (8) can be opened. The lock fittings (22) are placed on the inside of the frame (23) so the "bell" cannot be opened from the outside.

The lock fittings (22) is placed on an instantaneous arm making it difficult to open the "bell", if the hinge (30) is cut over.

PATENT CLAIMS

Introduction = the standpoint of the technique

The existing store containers for motor oils are simple, they are only used for storing of motor gas oil. A shell and two end plates form the fuel tank itself and the necessary sockets are placed upwards. Normally such containers are not provided with other bulkheads than the one forming the outer walls of the container.

These tanks can be provided with manual or electrical pumps for transfer of the fuel. The containers are pro¬ tected against theft by fixing the function of covers and purnps by means of a padlock.

Claims

PATENT CLAIM 1 (Introduction - the standpoint of the technique) .

Our patent claim bases on a mobile combination tank divided up into several rooms, of which one is intended for storing of others things than motor fuel.

The characteristic part

This store room is established especially for storing of secondary facilities, tools, and other things necessary for the machine operator. These components are stored at each their place in an extensible shelf system and the tank is characterized by a number of pipes forming the suspension for this shelf system. The pipes are fixed in an end cover and led through the centre bulkhead so that the pipes are placed inside the fuel tank.

The shelf system is mounted in this way to ensure a compact unit during transportation and at the same time it is made so that an crgonometric correct loading height is obtained during handling of the heavy auxili¬ aries.

PATENT CLAIM 2 (Introduction = the standpoint of the technique)

Normally filling sockets turn upwards and they are pro¬ tected against theft by fixing the function of the covers and pumps by means of a padlock, or by mounting a small locked cabinet over the pump unit itself. This cabinet is then secured by a padlock.

The characteristic: part

The tank filling sockets are placed upwards and the combination tank is characterized by access to these sockets through a "bell" (a door) which cannot be opened until a safety device placed inside the combination tank (room II) has been removed. A high internal frame makes unwanted access difficult even though that the hinge of the "bell" is removed. The "bell" is hinged at one side and secured at the other.

PATENT CLAIM 3 (Introduction = the standpoint of the technique)

The hereinafter mentioned structural member has not been seen previously in connection with mobile fuel tanks.

The characteristic part The characteristic part.

Access to the shelf system itself is created by opening an end cover hinged at one side and held by a handle at the opposite side. Approximately in the middle of the end cover there is a countersinking with a small opening through which a stationary steel eye will appear each time the end cover is closed fully.

The combination tank is characterized by securing the end cover with a padlock placed in such a countersinking protected against damage (from i.a. bolt cutters).

This structural detail has the effect that the end cover cannot be opend even though the end cover hinge is removed.

PATENT CLAIM 4 (Introduction = The standpoint of the technique) .

The characteristic part The combination tank is characterized by an accumulation box placed inside the tank to prevent oil waste from the shelf system and that filling of the fuel tank pollutes the external surroundings. The combination tank is here designed with a steel frame leading the oil waste to the accumulation box placed at the bottom of the store room.
