Calig, Pittsburgh, Pa. Application September 23, 1944, Serial No. 555,438 11 Claims. (Cl. BB3-_169) My invention Arelates to internal combustion en gines, and more particularly to means for supply ing and vaporizing liquid fuel thereto and the ig nition of the atomized fuel. ' ' One object of my invention is to provide an> improved form of vaporizer and ignition device for internal combustion' engines, which can read ily be applied to various standard types of gaso line or oil burning engines. ` ’ piston . l‘l is reciprocated to elect charges of oil _into the pipe 9 that leads to one ot the plugs l, »the fuel ilowing into the cylinder through one of the ports IB that leads from the header IB. The cylinder block I6 has a skirt portion isa in which _a loose iìtting plug I9 is reciprocated, the plug being loosely connected to the piston l1 by a pin 2|! and carrying a pin 2l that serves as a shaft for an anti-friction roller 22. A. spring 23 is in Another object of my invention is to provide a vaporizing and ignition system=of the character 10 terposed between the plate I4 and the pin 2l to urge the piston l'l downwardly and maintain the referred to wherein the necessity of a ntiming roller 22 in contact with a cam surface on a ro switch, a condenser, and-a carburetor ,is avoided. tatable plate 2d, the lower portions of the cylinder . Another object of my invention is to provide skirt lBa being slotted to permit vertical move means whereby the ordinary gasoline engine can ments oi’ the pin 2l.' The piston i? is recipro be converted to operate as an oil burning engine, cated during rotation of the cam plate 2t, the f with consequent fuel economy. raised surface on the cam plate coming into con Still another object of my invention is to pro tact with the anti-friction rollers 22 of the various _ vide an improved form of pump for supplying fuel pistons, successively. ' Y charges oi desired variable volumes to vaporizing 20l When applying the pump mechanism to an devices. As shown in the accompanying drawing, Fig. 1is a sideview of a portion of an internal com bustion engine with my invention applied thereto; - automobile engine, it may suitably be connected with the'tlmer shaft 26 that is commonly present on automobiles. To this end, the pump apparatus Fig. 2 is an enlarged sectional view,A taken on the 25 has a shaft 2l' that is coupled with the shaft 2S and is rotatable in the bushing i2. At its, upper line Iii-II of Fig. 1; Fig. 3 is an enlarged sectional _ end, the shaft >has splined or slidably keyed con viewoi a portion oi' the pumping apparatus andl nection with the cam plate 24 so that the cam of one of the vaporizing and igniting plugs of Fig. plate can be raised and lowered during rotation l, and Fig. 4 is a stili'further enlarged viewA of oi' the shaft. The cam plate 25 is supported on one of the plugs. 30 an anti-friction bearing unit 23 that is Slidabîe For convenience of illustration, I have shown on the sleeve l2, the bearing unit 2E being in my invention as applied to an automobile engine » turn carried by a collar 29 that has oscillatory 5, but it will be understood that «the invention may movement on the sleeve I2 and has a comming be applied to other types of internal combustion surface 30 on its lower edge that engages and is engines. The invention has the intake manifold _ 35 vertically supported by an anti-friction roller 6, but in this instance, said manifold will be used 32 which is journaled in the sleeve E2, it being only for the intake of air to mix with the atomized . fuel, in forming the explosive charges. The en gine shown is of the six-cylinder type, but for the usual spark plugs, I substitute fuel atomizing and vaporizing plugs 1. Each plug 'l is supplied from one of six fuel pumps 8, a pipe 9 leading - from each pump to its associated plug 7. understood that there are three c sur faces 30 and three rollers 32 at equally spaced points around the sleeve l 2. The camming collar 29 has connection with a pull-and-push rod 3i that may he operated from the driver’s seat or elsewhere to oscillate the collar 29 so as to raise and lower the cam plate The pumps 8 are supported on the engine block by a bracket il, or it can be mounted on the ordi 45 2d, to vary the amount of fuel that is elected from the pump into the line 9 and to the plug i, upon nary distributor mounting. The bracket il car ' each upward stroke of the piston i?. it ’ne ries a bushing l2 that in turn supports plates or spiders I3 and i4 that are -held in assembled rela tion by bolts i5, the plate l@ supporting the six pump cylinders 8 and a fuel" supply header i0 that has passageways communicating with the various pump cylinders. ° ' _ seen that during rotation or the shafts @i3-2ï, the pistons il will be raised in succession to sup ply fuel under pressure to 4their respective plugs l. The amount of fuel thus supplied will depend upon the length of stroke of the piston i?. When the collar 29 is in the position shown in Fig. l, the cam plate 2d and hence the pistons will move The pumps 8 are all of like construction and description of one will suiìice for all. Each pump comprises a cylinder block it within which a 55 to their lowermost points and hence idling charges or even no charges of fuel will be supplied. When _ „maag "member 52, and the lower end thereof similarly f the collar 23 is turned somewhat from said posi tion, the cam plate 24 will'be maintained at a higher plane andthe range of piston stroke will be longer, with consequent increased volume of fuel charges. Thus if the' cam plate is held at a , loose fitting and knurled, to'permit the flow of higher plane. there will be more fuel supplied - it is discharged into the combustion chamber. than when the cam collar 23 is adjusted to let fuel under pressure down past the stern, to the combustion chamber. The knurling of the mem bers 51. 5i, 41 and. 43 is such that the oil under pressure from the pumps 3 will be atomized as The upper end of the stern 56 is releasably the cam plate move farther down. Liquid fuel is supplied from a suitable source, locked in a socket member 53 by balls 59 in such manner that the stem is held against falling through an inlet. .33, past an upwardly closing 10 downwardly relative to thesocket but can have check valve 34 and through a central port 35 that some upward movement relative thereto. A communicates with the lateral ports in the header spring 3i is interposed between the socket mem i3 that in tum communicate with the cylinder ber 53 and a shoulder in the sleeve 43 to normally `ports i3.

' A priming device is provided for forcibly in 20 against the expansive force of the spring 6i, to jecting fuel and expelling air from the ports and the point at which the arcing stud 54 engages the passageways leading to the plugs 1, preliminary contact member 55. The continued application tostarting the engine when it has been standing of pressure will then be exerted on the upper end for 'some time and the passageways and ports are of the stem and on the enlarged head 51 of the 25 empty of fuel oil. This priming device comprises stem to move it further downwardly and permit the piston 31 operated by a .plunger handle 38 the forcing of oil past the member 51 and the that is normally held in raised position by a spring knurled surfaces to the combustion chamber. 33. Upon upward stroke of the plunger, the Upon retraction of fuel pump piston i1, pressure suctional force created thereby will draw the valve in the plug 1 will be relieved, allowing the spring 30 . 34 to its seat and create a vacuum force, which causes an inflow of oil through the inlet 33.
