Title: Grease filling device with grease dispensing tool

Utility model

The innovation concerns a grease filling device in which a grease pump with a hand lever is attached to a bucket for grease, has a suction pipe extending into the bucket and is provided with an outlet hose at the end of which a grease dispensing tool is provided.

In a grease filling device of this type, which is known from practice, the tool is a grease gun, to which grease is supplied by operating the hand lever. There are cases in which the grease must be applied over a large area and in a relatively thin layer; for example, hydrants are provided with antifreeze grease in vulnerable areas to enable the fire brigade to use the hydrants easily even in frost. In such cases, the grease gun is unsuitable.

One of the aims of the innovation is therefore to create a grease filling device of the type mentioned above, which is equipped with a tool suitable for applying thin layers over a large area. The grease filling device according to the innovation is characterized in that the tool that dispenses the grease is a brush that protrudes into the outlet hose with a hollow nozzle and is provided with an opening in the clamp between the hollow nozzle and the brush attachment.

The grease is fed to the brush via the hollow nozzle and the clamp opening, so that grease can also be applied easily from the grease filling device over a large area and in a thin layer. By connecting the brush, which is provided with the hollow nozzle and clamp opening, to the hose of the grease filling device, important

Applications achieve a significant improvement in the absorption of the fat*

It is particularly useful and advantageous if the bucket is provided with a bowl for holding the brush. The brush covered in grease can be stored in the bowl, so that parts are not accidentally soiled with grease.

However, it is particularly practical and advantageous if the bucket has a lid and the bowl for holding the brush is provided on the top of the lid. This is a favorable arrangement of the bowl in terms of space utilization.

It is also particularly useful and advantageous if the ratio of length to diameter of the brush bristles is from 1.4 to 1.7 , in particular approximately 1.5. Such a brush is well suited for applying grease. The length of the bristles is, for example, from 3.5 to 5.5 cm, in particular approximately 3.5 cm; the diameter of the bristles is, for example, from 2 to 4 cm, in particular approximately 3 cm.

It is also particularly useful and advantageous if in the bucket ., Grease is provided and the grease is an antifreeze grease, which ,-

is acid-free and at - 10°C and below essentially does not _t <

I stiffened. Such antifreeze grease is used, for example, by fire departments to treat hydrants and the use of a grease filling device in line with the innovation is particularly useful when treating hydrants with antifreeze grease .

The antifreeze grease is a soft grease that is easy to pump. The hose is e.g. 2 to 4 m, e.g. 3 m long. The bucket usually has a capacity of 5 to 50 kg.

The grease filling device according to the drawing has a bucket 1 with a round cross-section, the opening at the top of which is closed by a lid 2. In the bucket 1 there is a follower piston 3 with a sealing sleeve 4, which is characteristic of grease filling devices or their buckets. The follower piston 3 can be slid with a sleeve 5 on a centrally arranged vertical suction pipe 6. The suction pipe 6 also projects through a central sleeve 7 of the lid 2 and is fixed to the housing below the lid ^by means of a not shown compression spring, the ends ^of which are fixed to the upper edge of the bucket 1 by means of screws 9.

\J In the intake pipe 6 there is a piston rod 10 which can be moved up and down and which carries a piston 11 at the bottom, by means of which grease is fed from the bucket 1 to a connection 12 at the upper end via valves (not shown but known per se). For this purpose the piston rod T7 is moved up and down by means of a hand lever 13 which is supported on the intake pipe 6 via a joint piece 14 and has a handle piece 15 at the free end. A hose 16 extends from the connection 12 and has a F ¹ island 17 at the free end in which it receives a hollow nozzle 18 which is connected to a fitting 21 via an opening 19 in a clamp 20. The brush 17 is accommodated in a bowl 22 which is screwed to the lid 2.

The antifreeze grease used is also called hydrant grease and is water-resistant even at higher temperatures*. The antifreeze grease can be used at low temperatures and is suitable for cold storage, for example. It is a fully dewatered calcium soap grease and is short-acting and smooth. The operating temperature of the antifreeze grease is between -50°C and 100°C.
