'OIL-PUMP ATTACHMENT FOR GAS ENGINES.- i
Application filed June 28, 1922. Serial No. 571,531.
T0 all 'whom t may concern Be it known that I, GUY T. SEIDLE, a. citizen of the United States, residing at Stockton, county of San Joaquin, State of California., have invented certain new and useful Improvements in Oil-Pump Attachments for Gas Engines; and I do declare the following to be a full, clear, and exact description of the saine, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.
This invention relates to an oil pump attachment especially intended and adapted to be applied to the type of engine used in a certain well known make of car, the principal object of the invention being to provide for a better circulation of the lubricating oil in the crank case of the engine than is obtained with the system provided with the engine.
A second object of the invention is to provide a device for the purpose somounted as to be driven in connection with the cooling fan of the engine by the same belt as is used to operate said fan, -without altering the length of the belt or altering its regular position.
A third object is to provide a bracket or support for both fanl and oil pump which will take the place of the arm commonly provided, without however necessitating any changes being made to the engine and its parts other than the substitution of the new fo-r the old bracket. j
I have also mounted the oil pump with the fan in such a manner that no interference with the adjustability of the bracket, necessary when adjustment of the belt is desired, is had.
A further object of the invention is to produce a simple and inexpensive device andY yet one which will be exceedingly effective for the purposes for which it is designed.
These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.
In the drawings similar characters of reference indicate corresponding parts in the several views.
Fig. 1 is a front view of the attachment, as installed on an engine.
Fig. 2 is a side View of the co-mbined fan and pump unit, detached.
Fig. 3 is a rear end view of the same.
Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes a. substantially vertical arm having a bored hub or boss 2 on its lower' end adapted to fit the usual fixed pin 3 mounted on and projecting from the front end of the motor v Projecting below the hub 2 is a lug 5 adapted to beI engaged by the adjustable set screw 6 always vprovided on the motor to act on the corresponding lug of theusual arm.
At the upper end of the arm 1 is a bored boss 7 which receives vand journals a shaft 8, which extends beyond said boss at both ends. On the front end of the shaft is fixed the standard drive pulley 9 of the fan 10 mounted in connection therewith, while to the rear end of said shaft is fixed an oil pump gear 11 mounted in a casing member 12, the shaft 8 projecting into said casing and being journaled in a boss 13 formed therewith, which boss has a packing gland structurev 14Cy at its outer end.
Another gear 15 inside the casing12 and above the gear 1l meshes with the latter gear, forming a common type of gear pump, the casing being enclosed at its rear end by a removable cover plate 16.
A flexible intakejpipe 17 leads from the lower and rear end of the crank case of the engine (where the main supply of o-il collects) to one side of the casing 12 intermediate the pump gears. A discharge pipe 18, also flexible, `leads from the opposite side of the casing to the crank case at the upper and forward end thereof, preferably adjacent the timer gears of the engine. A branch pipe 19 leads from the discharge pipe, intended to be conected to any form of pressure gage (not sho-wn) to be mounted on the instrument board of the car, so that t-he driver may observe if the pump is working.
The pipes 17 and 18, before making connections with the pump casing, areprojected upwardly above the top of the casing in the form of an inverted U-shaped bend as shown in Fig. l, which no-t onlyinsures'the pump being primed at all times, but adds to the flexibility of the pipes.
Projecting downwardly from the casing 12 and formed integral therewith is an extension of plate 2O slotted as at 21, said slot being arcuate with the shaft 8` as an axis.
Extending through this slot is a bolt or screw 22 mounted in an arm 23 formed integral with and projecting horizontally from the arm 1, the arm abutting against the plate 20, and the bolt 22 being normally cinched up tight.
The members 1, 23 and 12 may therefore be considered as a rigid supporting unit or bracket for the shaft 8 and parts lconnected thereto.
By reason of the particular `form of adjustable connection used between the casing and arm 23, if it is necessary to alter the transverse setting of the arm 1 (usually on an angle) to alter the tension of the fan belt, the normal vertical position of the casing 12 may be maintained at all times, merely by loosening the bolt 22 before adjusting the arm 1, and tightening up the bolt again after the arm adjustment is made.
The preferred -position of the casinglQ is that in which the axes of the gears 11 and i5 lie in a common vertical plane, and there are two principal reasons for desiring this position to be maintained. First, because I have found the most efficient operation of the pump is thus had and secondly, because the clearance between the pump and cylinder block is necessarily so small that the casing cannot be angled and still miss the block.
It is of course evident that as the arm 1 is adjusted, the shaft 8, and consequently the casing 12, is raised or lowered as the case may be, but this, does not interfere with the operation of lthe pump, since the tleXibility of the pipes 17 .and 18 permits ofthe amount of movement necessary without unduly straining the pipes or breaking connections.
The purpose of the pump is to circulate the oil from the .lower and rear end of the crank case to the upper forward end thereof, which, with the system now provided, fails to receive a supply of oil adequate to suiliciently lubricate the various bearings.
From the foregoing description it will be readily seen that l have produced such a device as substantially fulfills the objects of the invention as set forth herein.
lVhile this specification sets forth in detail the present and preferred construction of the device, still in practicesuch deviations from such detailmay be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
Having thus described my invention, what claim as new and useful and desire to secure by Letters Patent, is
1. An oil pump attachment for motor vehicles comprising an oil pump member, a shaft therefor, a support for the shaft mounted for arcuate movement transversely of the shaft about a xed axis, and adjustable means connecting the pump and support whereby the vertical alinement of the pumpnaled, a portion of said casing being pro-- vided with an arcuate slot concentric with the shaft, an extension ,from the `support projecting to the slotted member, and a releasable bolt mounted in the extension and passing through the slot.
a. A pump attachment for engines comprising a support pivoted -fat one end on the engine, a shaft journaled therein, an arm provided with the support and yextending lengthwise of the shaft, and a pump casing mounted at the outer end of the arm and in which the shaft is also journaled.
5. A pump attachment -for'engines comprising a support pivotedl atene end onthe engine, a shaft journaled therein, an varm provided with the support and extending lengthwise of the shaft, a pumpcasing in which the shaft is also j ournaled positioned at the outer end of the. arm, vand means between thc casing and arm for supporting the casing from said arm while permitting of relative rotative movementof the casing and support about the shaft as anaXis.
6. A pump attachment for engines including an angularly adjustable support mounted ou the engine, and a driven pump structure mounted on the support for .adjustment independently thereof butin a similar plane.
In testimony whereof I aflix my signature.
GUY T. SEIDLE.
