This invention relates to oil filtering devices, and particularly to that type of oil filtering device used with internal combustion engines for filtering the oil in the circulating system to insure the bearings and moving parts being supplied with clean filtered oil.
The primary object of the invention is to provide a filtering unit which is hermetically sealed in a can, and a holder including a head having inlet and outlet pipes formed with piercing ends adapted to pierce the end of the can containing the filtering unit, establishing communication between the filter and oil line of the internal combustion engine of which it forms a part.
An important object of the invention is to provide an oil filter wherein the filtering element may be readily and conveniently changed without the use of tools, and eliminating the disagreeable and objectionable procedure necessary in the replacing of filtering cartridges, now in common use.
With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawings Figure 1 is a front elevational view of a filtering device, constructed in accordance with the invention.
Fig. 2 is a bottom view thereof.
Fig. 3' is a vertical sectional view through the device.
Fig. 4 is a sectional view taken on line 4-4 of Fig. 3.
Fig. 5 is a fragmental sectional view illustrating the lid of the can of the filtering device as punched by the inlet and outlet pipes of the device.
Fig. 6 is a view illustrating means for securing the lever of the device against accidental movement.
Fig. 7 is a fragmental elevational view illustrating the upper fluted end of the cartridge.
Referring to the drawings in detail, the device comprises the head 5 which is formed with an annular depending flange 6, which head is provided with an opening, though which the pipe 1 extends, and in which the pipe 1 is secured. The pipe i is formed with a beveled end defining a piercing prong 8 so located, that it will ATENT OFFICE pierce an opening in the center of the upper end of the can of the filtering device, to be hereinafter more fully described.
Disposed adjacent to the pipe I, is a pipe 9 which is also formed with a piercing point l0 designed to pierce the end of the can of the device, at one side thereof.
Openings II are formed in the pipes I and 9, adjacent to the piercing points thereof, which openings provide oil vents to facilitate oil flow.
The pipe I has connection with the pipe [2 that forms a connection between the pipe 1 and oil pipe line of the oil system of the internal combustion engine, while the pipe 9 is connected with the pipe i3 that also provides connection between the oil system and the filtering device, the pipes 9 and I3 constituting the pipes through which the oil passes from the oil system, into the filter, while the pipes l and i2 constitute the outlet pipes of the filter.
Secured to the head 5, by means of the apertured ears M which extend upwardly from the head 5, is the U-shaped yoke i5 which hangs downwardly from the head, and is pivotally connected with the lever it that is pivotally connected with the supporting disc ll that provides a support for the can containing the filtering unit 18. The pivot point between the supporting disc and lever I6, is indicated by the reference character 19, and the connection between the yoke 15 and lever I6 is eccentric, with respect to the pivot point Is, to the end that as the lever I6 is swung from the full line position, shown by Fig. 3 of the drawing, to the dotted line position, the supporting disc or shelf H is elevated, forcing the upper end 20 of the can 2i into engagement with the piercing points 8 and it), with the result that the piercing points pierce the upper end 20 of the can providing communication between the interior of the can, and the pipes l2 and 13.
The can 2! which contains the filtering unit, is provided with the gasket 22 that fits against the annular rib 23 depending from the inner surface of the head 5, providing a fluid-tight connection between the upper end 20 of the can 2|, and the head to insure against leakage of the 011 at this point.
The reference character 24 indicates a supporting arm which extends downwardly from the head 5, the supporting arm operating through the guides 25 that extend laterally from the bar 26 formed integral with the supporting disc or shelf H, the guides 25 sliding over the;
supporting arm 24, as the supporting disc or shelf I! is moved vertically, as described.
A spring latch 21 is secured to the lever 16 and is so constructed that it will move upwardly and contact with the outer edge of the supporting disc or shelf 11, holding the supporting disc or shelf in its elevated position. An opening 28 is formed in the lever 16 and is disposed adjacent to the spring latch 21, for the reception of a pin 21 to prevent movement of the spring latch under normal conditions, to insure against the spring latch releasing, due to vibrations of the engine or vehicle, which would allow the supporting disc or shelf H to drop down and release the device.
The filtering device includes a cylindrical casing with its ends closed by the fluted-discs '30, the discs 30 being of diameters greater than the diameter of the casing 29, so that the edges of the discs contact with the inner surface of the can'2l. The portions of 'the'discs 30 which extend beyond the outer surfacesof the casing 29, are serrated, providing openings or passageways 3i between the casing 29 and can 2!, through which oil may pass.
The casing 29 maybe constructed or any desirable material, and is provided with perforations, to permit oil passing through the space between the casing and'can 2 i, to filter through the filtering unit 18.
Extending longitudinally through the center of the filtering unit 18, is the tube 32 which is formed with perforations 33 to allow oil to pass into the tube, from where the oil passes into the pipe 12.
The ends of the tube 32, project above and below the discs 30, where they are supplied with sleeve gaskets 34 that maintain a fluid-tight connection between the ends of the tube 32 and inner surfaces of the upper and lower ends of the can 21.
The reference character .35 indicates a bracket by means of which the device may be supported on a motor vehicle or an internal combustion engine.
In the form of the invention as shown by 6 of the drawings, the lever .36 is shown as provided with an opening that falls directly opposite to the hook 31 formed on the arm 38 that is secured under the disc or shelf 39, the opening accommodating a wire such as indicated at 40, for securing the lever 36 against accidental movement, due to vibrations of theengine or motor, to release the lever 36 and allow the filtering unit to move to its inactive position, :for removal and replacement.
From the foregoing it will be seen that due to the construction shown and described, I have provided a filtering device for the oil system of a motor vehicle or internal combustion engine, wherein it is only necessary to lower the lever l6, allowing the disc or shelf I! to slide downwardly. The can 2|, together with the filtering unit 18 may now be removed and replaced with a new filtering unit and cartridge. As the lever 16 is swung upwardly, it is obvious that the piercing points of the pipes l and will puncture the upper end closing the can 2|, the pipes entering the space between the upper end 20 and upper end of the filtering unit, establishing communication between the oil or lubricating system of the motor vehicle or engine with the filtering device. The oil in passing through the filtering device will be treated or filtered to remove foreign matter which is injurious to bearings and moving parts lubricated by the oil.
In view of the foregoing detail description, a further detail description of the device is believed to be unnecessary.
Having thus described the invention, what .is claimed is:
'An oil filtering device comprising a can having closed ends, in which a filtering element is housed, a holder for saidcan comprising a stationary disc on which said can is positioned, a vertically movable head having an annular depending flange adapted to fit over the top of the can, a U-shaped yoke pivotally connected to the stationary disc and head, adapted to .move the head downwardly over the upper end of the can as said yoke is moved downwardly, pipes extending through the head, said pipes having piercing ends disposed within the confines of said depending flange of the head, through which oil circulates, said piercing ends of the pipes adapted to pierce the can in which the filtering element is housed, establishing communication between the pipes and can, as the head moves over the can clamping the can on the stationary disc.
