UNITED STATES PATENT OFFICE.
EDWARD B. BLAKELY, OF CHICAGO, ILLINOIS, ASSIGNOR TO B. M. HVID COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF MICHIGAN.
LIQUID-FUEL FEED.
Specification of Letters Patent.
Patented Feb. 15, 1921.
7 '0 all whom it may concern:
Be it known that I, llmvann B. BLAKELY, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid-Fuel Feeds, of which the following is a specification.
My invention relates to fuel feeding devices for hydro-carbon engines and particularly to means adapted to be associated with oil engines of the 1; pc in whic liquid fuel is fed directly to tie cylinders.
In engines of the type described and particularl those of the Hvid type, such as shown in Patents Nos. 1,245,312, of Nov. 6, 1919, to lilakely, and 1,283,197, of Oct. 29, 1919, to Hvid, the fuel in liquid form is delivered h gravity to the igniting device where it 1s suitably disposed of in order to secure the highest ei'liciency. In engines of this type the entrance of the liquid fuel to the ignition cup is controlled primarily by a needle valve and secondarily, by a puppet valve, the latter valve being opened in consonance with the main intake valve. It sometimes happens that an engine stops at a point where the puppet valve is open, with the result that the auxiliary supply of oil which is maintained in an elevated container, escapes past the needle valve into the cup and finally into the cylinder with the result that upon attempting to start the engine considerable damage is likely to be in curred.
To obviate this Ihave provided means whereby a constant supply of fuel is provided, and yet in which there is no reserve amount of oil which may escape in the manner described. Particularly in multi-cylinder engines, a pump is commonly provided for elevating the oil to the gravity tank, the
over-flow returning to the main tank. This pump is utilized in the present design but no elevated tank is employed. A. casing is provided having inlet, outlet and over-flow openings, the over-flow being controlled by a valve carried by a diaphragm, the an l'angement being such that whenever pres sure is exert d. by the liquid within the casllragm is moved and the over flow valve opened, with the result that a constant supgly of oil is maintained within f, however, the engine should stop, the pressure is immediately reduced in "It will be seen that if the engine is the casin to a point at whichthe over-flow valve is c osed and the casing is kept full of oil. Immediately on the starting of the engine the operation continues as before.
The invention will be more readily understood by reference to the accompanying drawings, wherein,
Figure 1 is an elevation somewhat diagrammatic in form, showing a preferred arrangement of my controlling device;
1* 1g, 2 is an enlarged vertical sectional view through the controlling device, and,
Fig. 3 is a longitudinal sectional view throu h an igniting device of the Hvid type.
In the drawings it will be seen that the engine indicated at 10, is provided with an igniting device 11, a sectional view of which is shown in Fig. 3. Fuel is supplied to the device by means of a tube 12, having a bend or goose-neck 13, therein and which ma or may not be provided with a valve 14. he main supply of fuel is carried in a tank 15, and is withdrawn therefrom by means of a pump 16, and discharged, through the pipe 17 into the lower or inlet opening of the con trolling device which forms the subjec matter of this invention.
The igniting device, as shown in Fig. 3 is in the form of a lug 18, and is provided with a small air in ct opening 19, a needle valve 21), which primarily controls the amount of liquid fuel, a uppet valve 21, adapted to be opened on t e suction stroke of the engine by a suitable means not shown, and an igniting en 22, having small escape apertures 23, all or the purpose fully set forth in the patents heretofore referred to. stopped in such condition that the puppet valve 21,
is in open'position, any lliglld fuel contained in an elevated tank will ruin into the cylinders with the objectionable features heretofore noted.
In order'to obviate this dilliculty I revide the device best shown in Fig. 2, w ich is in the form of a casing com sod of two halves 24, 25, suitably joined b; means of flanges and screws, thereby providing a. space 26, having an inlet 27, an outletilS, to the pipe 12, and an over-flow outlet 29, which connects to the pipe 35), and serves to discharge excessoil into the tank 16. The space 26, is divided by means of a (fiaphragm 31, clamped between the two halves of the rusing and supporting a valw n, which con trols the over-flow outlet 2%). A spring 33, bears against the diaphragm, the pressure exerted being ,ontrolled b means of an adjusting tlnnnh-srrew 34. lhe adjusting device is provided in order to suitabl control the delivery oi diti'erent fuel oils. he Hvid engines are adapted to burn heavy oils such as crude petroleum as well as the lighter hydro-arbons and as these oils have different degrees of viscosity, a greater or less degree of pressure is required in order to elevate the same and overcome the surface tension developed in the passages to the point of use. The device operates as follows: Assuming the engine in operation, the pump will deliver a constant supply of llquid into the chamber 26. Such quantity as is necessary for combustion will he delivered through the pipe 12, to the igniting device. However, as any material pressure develops within the chamber, the diaphragm 31, will be deflected and the over-flow outlet 29 opened, thus permitting the excess of oil to return to the tank. Should the engine be stopped, the pressure will immediately be reduced and the over-flow outlet closed, thus trapping the oil contained within the chamber 26. Upon resumption of operations the first stroke of the pump will again serve to deliver fuel to the igniting device. I provide the bend in the pipe 13, in order that there may be a small quantity of oil retained in the pipe and connections, an amount being provided at least sufiicient to carry the engine over several cycles. This is a safety f ature and is not essential in practice.
Obviously the exact form and arrange ment of the parts is not essential to secure desirable results and modifications may be made in the construction shown without departure from the spirit of my invention.
I claim:
1. In a device for feeding liquid fuel to hydria-arbon engines, the con'ibination of a. liquid fuel igniting device, a tank located below the level of the igniting device, a pump for elevating liquid fuel, a controlling device connected to the pump and igniting device and located at a point below the latter, said controlling device including a casing having a spring-pressed, valve-controlled over-flow outlet, and means for trapping liquid fuel Within the casing when the pump is stopped, substantially as described.
2. In a liquid fuel feeding device for by drocarbon engines, the combination with the engine of a liquid fuel igniting device, a tank, a. pipe connecting the tank and the igniting device, a pump, and a controlling device located in said pipe, the tank and controlling device being located below the level of the igniting device, said controlling device including means for maintaining a constant pressure within the pipe and for trap ping liquid fuel within the pipe between the ngine and contiolling device when the engine is stopped, substantially as described.
