HAROLD A. EKLUND, OF TULSA, OKLAHOMA.
OIL INJECTOR.
Application filed September 14, 1922. -Serial No. 588,228.
To all whom it may concern:
Be it knownthat I, HAROLD ANDREW En- LUND, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented new and useful Improvements in Oil Injectors, of which the following is a specification,
This invention relates to devices for containing and injecting oil or other lubricants into motors, parts of machinery or other parts to be lubricated, and particularly to a device for injecting oil of more or less heavy or viscous character through the lubricant inlets of motors or parts of ma ehinery to be lubricated, and one object of the invention is to provide an oil injector which is simple of construction, reliable and efficient in action, not liable to get out of order, and by means of which oil of greater or lessspecific gravity may be easily and quickly injected through the lubricant inlet of the motor or part of machinery to whichv the oil is to be supplied.
A further object of the. invention is to provide an oil injector which will operate for, long periods without cleaning or repairs, which may be constructed, installed and operated at small expense, which ensures the positive introduction of the oil in a cleanly manner to the part to be supplied, and which enables measured quantities of oil to be supplied with extreme :accuracy, thus ensuring the delivery to the customer of the right amount of oil he pays for.
With :these and other objects in view, the
invention consists of'the features ofconstruction, combination and arrangement. of parts, hereinafter fully described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a central vertical section through an oil'injector constructed in are cordance with my invention.
Figure 2 is the same.
Referring to the drawing, .1 designates an outer containingcasing or cylinder, closed by topand bottom, concavo-convex heads 2 and 3 and sub-divided by an internal partition 4 into an upper air pressure chambenfi and Ta lower oil containing and pressure chamber {6. The partition 4: closes the two chambers5 andG against communication, except as hereinafterdescribed, and is-seeurely united at its periphery to the wall of thecasing 1 against any possibility of a horizontal section through leakage of pressures between said chambers. The cylinder 1 is made as a whole of'metal or other suitable material of adequate strength to sustain the desired working pressures.
Arranged within the air chamber5 is a primary oil reservoir tank. or chamber 7. This tank 7 is of less diameter than the chamber 5 and terminates at its lower end a de sired distance abovet-he partition 4. At its upper end the tank 7 projects outwardly through an opening i the head 2 and is provided with a removable cover 8. At the point of passage of the tank 7 through the head '2 the joint is securely sealed against any possibility of the escape of air' presf sure from thechamber 5. The tank. 7 is of'a capacity to contain, up to a certain level, a predetermined quantity or amount of oil in gallons or other'units. This. oil may be supplied to the tank 7 through the open top of said tank when the cover .8 is removed. Extending vertically within the. tank 7 is van indicator 9, consisting preferably of a strip of metal or other material extending upwardly from the bottom of the tank and terminating-at 'the maximumv oil level therein. This strip may be fixed in position in any-suitable manner, and'is pro.- vided with graduations or indications 10, indicating the amount of oil contained in the tank at given levels. The graduations on this indicator strip may be inspected at any time upon removal of the cover 8 Connecting the lower end of thetank'i' with the oil pressure chamber 6 is. an oil feed pipe or conduit 11 having arranged therein a check valve 12, which valve is adapted to open, when the chamber 6" is empty and pressure removed therefrom, to permit oil to flow from the tank? to the chamber 6 to fill the latter, thc valve .12 closing to prevent any possibility'ofbackflow ofithe oil The chamber G-may be, and preferably is, a measuring chamber havmg a given capacity, or adapted to hold a 5 measuredquantity of oil or lubricant to be dispensed, so that each time said chamber 6 is emptied an accurate amount o-f'oil or lubricant will be delivered] The oil is dis-: charg'edfrom the chamber 6 tlirougha fle2iible discharge pipe13having a terminal charge' ozzle -14 and a controlling andicutofl'valvel5. i
Connecting the air pressure ichamberfi' with the extreme top" portion of "th 911 pressure chamber is a pressure feed pipe 16. This pipe communicates at its-upper end with the chamber 5 and with an air supply pipe 17 having a controlling and cut-oil valve 18 therein. The pipe 17 may lead from a pump or other source of compressed air supply, or may be adapted for connection with a flexible hose pipe vleading from such source of supply, whereby the chamber 5 maybe recharged with air to maintain a given working air pressure therein. A gage 19isv provided at the top of the pipe 16 so that the internal pressure within the tank 5 may at all times be ascertained and indicated. At the lower end of pipe 16 is an-air relief and level-indicating valve 20, the valve member of which ma-y be provided with a depressible stem21 and a valve closing spring 22, by means of which stem the valve -may be -manually'cpened and held open for a desired period, the spring serving to automatically close the valve when the stem is released. Arranged in the pipe 16 between .the air supply connection- 17 and; the said valve 20 is a pressure teed valve 23 which'may beopened'and closed to control comunication between the air pressure chamber 5 and the oil pressure chamber .Inthe operation of the device, as thus constructed, the tank 7 is charged with Oll which flows therefrom through the pipe '11 into thechamber 6, the supply being continued until the oil reaches the maximum level in the tank Tm While the chamber 6 is being filled with oil, the stem 21 of valve 20 is held depressedto allow the air in said chamber 6 to ventcto the atmosphere, said stem being released to allow said valve to close at the moment oil begins to show at the valve outlet, giving an indication that the chamber 6 has been completely filled.
Valvev18 is now opened,'while the valve 23 remains closed, to charge the chamber 5 withcompressed air to the desired pressure, after which valvelS is closed. The apparatusis now ready for operation for the dispensation of oil, and in discharging the measured quantity of oil from the chamber 6 the valves 15 and 23 are opened, the valve 23ral1owing compressed air to pass from;
the chamber 5 to the chamber 6 to expel the oil outwardly through'the pipe 13 and discharge nozzle 145' Valves 15 and 23 are then closed and 'valveQO again. opened to allow escape of the remaining air pressure from chamber 6 and said chamber to refill with oil from the tank 7, after which valve 20- isallowed to close, thus priming the apparatnsin readiness for a subsequent oil discharge action. The nozzle? 14 may be of such sizeas to allow itto be conveniently enteredj-intothe filling hole of the motor orother part of machineryto be supplied with the 1ubricant,=whereby the oil willbe discharged in a cleanly ,manner. and under 1 mama required pressure to the elements'to be supplied; Measured quantities of oil may thus be delivered in a ready and convenient manner and successive discharges of measured quantities made, when required, to make up anygiven amount.
As before stated, upon removal of the covers the indicator-l) within the tank 7 may be viewed, enabling the operator to tell exactly the amount o't oil contained in the chamber 7 and tank (Sat any-tiine- If the quantity contained is known, or thein" dicator 9 inspected before a discharge action, assuming that less than the measured quantity of oilpin chamber 6 is tobe expelled, the operator may determine theamount of oil expelled by again inspectingtheindicator 9, from which he can-rcadilvcalcu late from thereading of the levels given-be-- fore-and-atter the discharge actiomthe exact amount of oil dispensedw From the foregoing description, taken-in connection with the drawing,-the construe-- tion and mode of operation of myimproved oil dispensing device willhe readily understood, and it will'be seen that it provides a device of this character whichis simple of construction, reliable and; eftic'ient'in action, and contains nocomplicatedparts or packings liable to get out of order orto require-frequent cleaning or repairs. Also it will be seen that it-provides a device by means of whicha measured quantityof more or less oil may be dispensed'and'positively forced into the oil receptacle of the motor or element to-be supplied.- Further more-, it willbe seen thatit provides a device which is easily handled and cleanly in operation-andin which'the oil is protected at all times against the access of dirt -or; otherforeign particles The device maybe; a fixture in a garage or other oil dispensing establishment, orit maybe mounted upon a wheeled support so as to be readily -movable fromplace to place for use.- we
