Definitions

• Oil filters of the kind which in addition to a filter part includes a cylindrical, often oblong container, are used for purifying the oil in engines of various types, e.g. diesel or petrol engines for trucks or the like.
• Such filters are at one of their ends provided with a threaded opening by means of which the container can be screwed into a connection to the lubrication system of the engine.
• the system is emptied through a plug or otherwise, for instance as disclosed in the Swedish patent application 8303510-5.
• the filter remains however filled with oil and if the filter also is to be changed in connection with the oil change, this can result in considerable difficulties when the filter is removed, which is normally done manually.
• the present invention is intended to remove the above-mentioned drawbacks and make possible a convenient quick and clean change of oil filter containers.
• a hole punching tool is arranged to make possible the opening of a draining hole in the first container before removal thereof so as to drain liquid from said first container to said second con ⁇ tainer whilst lowering the liquid level in said first container.
• Fig. 1 is a simplified section through an oil filter made in accordance with the invention and shown in a state of use.
• Fig 2 is a similar section showing the filter in connection with the removal thereof.
• Fig. 3 is a partial section of a filter according to an alternative embodiment and Figs. 4 and 5 are perspective views showing two different embodiments of a hole punching tool.
• FIG. 1 generally denotes a con- ventional oil filter in the form of a container which includes a cylindrical wall 2 as well as a bottom 3. In the end part 4 being opposite to the bottom there is an opening with a thread (not shown) for screwing the filter container into the connection of the lubrication system of an engine.
• the container also includes a filter part( not shown ) for filtering the oil passing through the container. As shown in Fig 1 the container is normally entirely filled with oil 5 when connected to and forming a part of said lubrication system.
• a second container generally denoted 6 is associated to the filter container 1, said second container in this case being mounted to the bottom end of the container 1 and extending in extension thereof.
• the container 6 too includes a cylindri- cal wall 7 as well as a bottom wall 8, said cylindrical wall 7 being fitted onto the outer side of the con ⁇ tainer 1 and in a suitable manner sealingly connected thereto e.g. by means of a sealing ring 9.
• a hole punching tool associat ⁇ ed to the second container 6 and in the form of a striking pin 10 is mounted in a sleeve extending inwardly fro the bottom 8, a sealing ring 12 being connected to said sleeve in order to seal the area between the inside of the sleeve and the outside of the striking pin.
• the pin 10 on its free end protruding from the container 6 is provided with a plate 13 against which e.g. a hammer can be st ⁇ uck.
• Figs. 4 and 5 illustrate two embodiments of the said striking pin.
• the pin at its striking end is provided with a box 14 being U-shaped in section and having two cutting edges 15,15' which extend obliquely backwards from a frontal edge portion 16.
• an abutment 17 serving as driver.
• the box 14 is forced into the bottom 3 of the container 1 the edge portion 16 together with the cutting edges 15,15' will cut out a U-shaped tab in the bottom wall.
• this tab is engaged by the abutment 17 the tab will be carried along and swung into the container while forming a substantially rectangular opening in the bottom wall 3, the oil in the container 1 being able of flowing through the opening and the lateral opening 18 in the box 14.
• the box 14 is substituted for a short tube piece 14' having an obliquely cut oval cutting edge 19 and a carrier abutment 17'.
• the tube piece 14' one or more drainage openings 20 are cut out. In this case a circular tab will be cut out in the bottom wall 3.
• FIG. 3 an embodiment is shown where the cylindrical wall 7 of the container 6 has been provided with a clamping ring 21 that exceptionally reliably holds the container 6 to the filter container 1.
• Fig. 1 the filter container is connected to said lubrication system and thus filled with oil 5 ' .
• the striking pin 10 is here in an inoperative position out of contact with the bottom wall 3.
• the container 1 can be unscrewed without any risk that the oil overflows and flows down the outside of the container.
• the filter change can be carried out in a clean and convenient way without risking that the operator loses his grip of the con ⁇ tainer or soils his hands.
• the second or drainage container 6 can be formed as an intergral part of the filter container itself already in connection with the manufacture thereof instead of being formed as a supplementthat can be fitted to a conventional filter.
• other arbitrary hole punching means than just a striking pin can be used. It is for instance possible to use a closure device that is normally screwed into a threaded opening in the bottom wall 3 and that can be unscrewed when oil is to be drained into the draining container 6.
• the position of the striking pin or hole punching tool limited to the central position shown in the drawings in that it of course can be positioned any ⁇ where on the bottom wall 3(or even on the cylindrical wall 2 if the geometrical design of the container 6 is other than that shown in the drawings).
• the draining container of course partly or entirely can be designed to be placed on the outer side of the cylindrical wall of the filter container, especially in the case it is desirable to keep the overall length of the filter arrangement as small as possible.
