01L STRAINER.
Application filed November 23, 1925. Serial No. 71,000.
. My said invention relates to oil strainers for lubricating systems adapted to be applied Within the pipe line through which the lubricant is forced under pressure to the 5 parts to be lubricated during its cycle of operation. i
An object of the invention is to provide a strainer having a large straining surface and through which the oil will pass from the outside to the inside of the same so that the impurities will not be collected within the strainer but within the casing inclosing the same.
Another object is to provide a device of this character having means for preventing stagnation by causing the strained medium to be discharged from the entire length of the strainer instead .of from a relatively small area.
A further object of the invention is to provide a strainer having means for holding the same in a non-collapsed position and additional means for permitting the oil to be discharged from the strainer casing if the strainer should become clogged thereby preventing the engine burning up for lack of oil.
Figure 1 is a central longitudinal section of my device, and
Figure 2, a detail view of a ring for holding the strainer bag in non-collapsedposition.
Referring to the drawings my invention comprises a supporting head 10 having an inlet passage 11 and an outlet passage 12. Said head is provided with an upstanding portion 13 having apertures for the accommodation of fastening elements, not shown, and a flange 14: having apertures spaced along the same.
A relatively thin hollow casing 15 is attached to the supporting head said casing being open at one end and having a flange 16 about its open end provided with apertures corresponding to the apertures in the flange 14. Bolts 17 are disposed within the openings of the contiguous flanges for securing the casing 15 to the head 10 and a gasket 18 is preferably provided between said casing and head.
' The inlet and outlet openings for the oil are preferably spaced one adjacent the periphery of the head and the other at the center thereof to permit the 011 to pass through a straining medium disposed longitudmally of the casing between the center and circumference thereof. In the present instance I provide a flannel bag or sack .19 and attach the same by means of a ring 21 to a supporting disk 20 secured within the top of the casing by means of a stud 22. The bag 19 is preferably several times as long as the casing 15 and is circumferentially convoluted or accordion shaped'in order to afford the greatestpossible amount of straining surface and in order to hold the bag in a compact operative position I provide alternate small and large rings 23 and 24 respectively. The large rings 24 being placed within the bag 19 and the small rings 23 being inserted over the outside of the bag 19. The bag when so formed has a plurality of deep and narrow corrugations and has somewhat the appearance of a J apanese lantern. The free end of the bag 19 is provided with only a small opening through which extends the extremity of a pipe 25.
The pipe 25 has its inner end supported in the outlet passage 12 of the head 10 and sa1d pipe extends longitudinally through the bag 19 to a point closely adjacent the bottom of the casing 15 and is closed at said lower end by means of a plug 26. Said pipe 25 is provided with small openings 27 spaced longitudinally of the same in order that oil entering the bag 19 willbe discharged from all portions of the bag in substantially equal degree. By omitting the pipe 25 the upper portion of the bag will perform the straining operation and the oil would be discharged only from the upper end permitting stagnation of the oil in the lower portion of the bag and a smaller straining surface would be utilized.
It has been found very desirable to reverse the circulation of the oil so that in- Such in the casing. In accomplishing this reverse fiow it is necessary to provide some means for holding the bag against collapse caused by the pressure of oil on the outside thereof which collapsed condition would prevent the oil from reaching the center tube 25 from which it is discharged. I therefore form the larger inside rings 24; in the shape shown in Figure 2 or with portions of its circumference folded in to form inwardly directed fingers 24' which engage the tube 25 when sufficient pressure is applied to the oil. To reinforce the rings 24: the outer ends of the fingers 24 are welded or otherwise fastened together.
A strainer of the above character will not easily become clogged, however, if it does become clogged the motor will get very hot and be very greatly damaged or burnt up and to obviate this difliculty I provide passages 28 and 29 forming a by-pass from the casing to the outlet 12. The passage 28 is provided with a relief valve 30 held on its seat by means of a spring 31 housed in a plug 32, which forms a closure for the outer end of the passage 28. The outer end of the passage 29 is also closed by a removable plug 88 to permit access to said passage if for any reason it becomes necessary. The valve 30 may be set at the desired pressure and the oil will enter through inlet 11 and pass through the strainer and be discharged through outlet 12, however, should the oil pressure increase in the casing the valve 30 will open and permit the oil to by-pass into the discharge passage until the pressure returns to normal.
' Although I have described the oil as entering through inlet 11 and passing from the outside of the .strainer bag to the inside and out through outlet pipe 12, nevertheless the circulation may be reversed if the same is deemed desirable for any reason.
It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit myself to what is shown in the drawings and described in the specification but only asindicated in the appended claims.
Having thus fully described my said inventlon, what'I claim as new and desire to secure by Letters Patent, is:
