This invention relates to-improvements in a means and method for readily and efiiciently mixing-a motor fuel anda'lub'ricating liquid in the one operation of removing the two liquids from their respective storage tanks.
Great quantities of mixtures of gasoline and lubricating oil are consumed annually as fuel for the usual two-cycle gasoline engine, in which the gasoline and oil are mixed in suitable proportions before being fed to the engine. More particularly, the greatest use in the above category is in so-called outboard motors." With the vast increase in theuse of outboard motors, which use variousproportions of lubricating oil mixed with gasoline, there is a real need for a pump whichwlilll t e '7 of gasoline, usinga heavy grade of oil, whereas for racing, as high as two pints of very heavy oil is required to be mixed with the gasoline. There are some five or six blends of .motor oil and some three grades of gasoline ly satisfactory. The procedure usually fol-.
lowed by outboard motor users is to purchase a quantity of gasoline and pump it into their gasoline tank; then place what they consider a suitable proportion of oil into the same tank, assuming that, inasmuch as the two substances are miscible, thatall requirements forproper operation have been met. To one skilled injthe art thishaphazard method is obviously objectionable to the proper opera tion of the engine and is aprocedure notcontemplated by the engineTdesigner as desirable for efficient operation, "since the oil in the tank immediately settles to the bottom ings and following description.

and the desired intimate mixture is not obtained. l r V Accordingly, "one of the important objects of the present inventionis to provide a novel method and means for intimately mixing varying proportions of oil and gasoline as desired at the same time these liquids are being dispensed ata service or filling station.
Another important object ofthe invention is to provide aconvenient means for readily changing the proportions of the mixture.
provided, the stroke of one of the pumps being preferably maintained constant, whereas the stroke of the other pump may be varied by a suitable gear change mechanism, or "if desired, the stroke 'of each pumpmay be variedmf f 1 Other and further important objects of the invention will be apparent from the draw?)

The two cylinders 2 and 3 are shown vertically disposedwithin the tank and positioned 'parallel to each other, but thepresent invention 0 its broadest aspect does not contemplateany specific disposition-of the said cylinders.

A head lecomprises a closure for theme Q I tom of the cylinder. 2. Similarly, a head 5 forms aj-cl'osure for the bottom of the cylin relation to the cylinder 3 as do the corresponding members v6, 7 and 8 bear to the cylinder 2. In either case the threaded connecand-3 are tion of the two nipples to therespective heads is not shown inasmuch as this means of connection is conventional and will be apparent to those skilled in the art.
Slidably positioned within the cylinders .2 pistons 12' and 13, V respectively. Rigidly connected to the pistons 12 and. 13 are piston rods 14 and 15, respectively. Each of the piston rods 14 and 15 extends through a head or. top 16 of the tank 1 and terminates respectively in racks 17 and 18. i
Mounted upon the upper portion of the tank 1 are two standards or brackets'l9 and 20. The bracket 19 containstwobearings, a
. lower bearing 21 and an upper'bearing 22.
The bracket 20 contains three bearings, a
lowest bearing 23 which is in alignment with the bearing 21, a middle bearing'24 which is in alignment with the bearing 22,. and an uppermost bearing-25. .Rotatably mounted I in the bearings 22' and'24 is a shaft 26, upon one end of which is positioned a crankhandle 27. A sprocketwheel 28 is mounted upon the-other end of the shaft26,and isadapted to turn therewith. 1
A pinion 29 is rigidly mounted upon the shaft 26i'ntermediate the standards 19 and 20 and adjacent the standard'19. This gear is adapted to mesh with a spur gear 30 which in turn is loosely mounted vupon a shaft 31.
' A pinion 32 is also mounted loosely upon the. shaft 31 and'is connected to the gear 30'to turn therewith. Thislast mentioned pinion ,meshes with the rack 17 and, as is obvious, vlnovesthe rack when'the handle 27 is turned.
7 It can be readily seen that the movement of I the handle '27 the rack 17 and hence the piston 12,-are constant, but'in the broadest a pect of this invention, .byconventional transmissiongearing (not show) the relation-of themovements of the above mentioned memhers may be varied at will. This gearing if desired may take a formsimilar to the change speed gearing associated with the rack 18,
ltoibe hereinafter fully described;
crank 27 the shaft 35 is rotated. Two sprockfet wheels 36 and 37 are rigidly mounted upon the shaft 35 intermediate the standards 19 and 20'. Chains 38 and 39 cooperate respectively with the two sprocket wheels-36 and 37 Hand operatively c o'nnect the wheels 36 and 37 to a pair ofsprocket wheels 40 and 41,-re-
spectively. The wheels 40 and 41 areloosely tive'ly I 1 by an obvious manipulation of the clutch as shown-at 49 and 50, respectively, and, ad-
mounted upon the shaft 31 and both turn when the crank 27 is turned.
Keyed to shaft 31 is a clutch collar 42, said clutch collar being adapted for restricted. slidable movement dependent upon the length of a slot 43 provided in the shaft 31 intermediate the two wheels 40 and 41. Each of the ends" 44 and 45' is formed. so as to register with corresponding notches 46 and 47 provided in the wheels 40 and 41, respec- 7 I The sprocket wheels 36 and 37 are prefer- V ably of the samediameter, whereas the wheels 40 and 41 are of different diameters. Hence,
collar. 42 theshaft 31 may be madeto rotate at various speeds relative to the crank handle 27.] Rigidlymounted upon the shaft 31 and adapted to mesh withthe rack 18, is a pinion 48. Therefore,;for a given stroke ofthe piston 12in the gasoline cylinder 2, the piston 13in the'oil cylinder 3 maybe moved various fractions of a stroke. I 1
, In'operationthe intakesi7 and 10 are connected to storage tanksaof gasoline and oil, respectively. Assume for the sake of illustration that both cylinders 2 and 3 are filled V V with gasoline and oil, respectively, and further, that a certain percent mixture is desired] The'gear ratio can readily beset and the crank turned. Thepistons ri'sein the cylinders at a rate proportional to the respective percentages. of gasoline and oil desired.
The tops of .the cylinders 2 and 3 are-open, jacent the'said openings, there are compartments 51 and 52, respectively. From the two compartmentsthegasoline and oil-enter an e outlet pipe 53 and thence through a hose, or the like '(not shown) to the tank supplying- 0 the motor. The swirling motion of the '1iq ui'd entering and passingthrough the outlet pipe 53 and the hose isrsuflicient to thoroughly mix the two fluids toproduce a'mixture satisfactory for the purpose. 11
In Fig. 3 a slight'modification of the in .vention is illustrated, wherein the-reference numeral 54indicates generally the usual gasoline pump, having a conventional crank handle 55. A'pipe'56 extends upwardly from 11 the pump proper and serves the double purpose of being an outlet for gasoline from the I 1 pump and a suport for a platform ,56. Mounted upon the platform 56 is a cylindrical container 57. A piston (not shown) is operat-ively positioned in thecylinder'and the piston rod thereof is provided with rack teeth, as shown at 58in *ig. 3; Positioned adjacent the rack 58 is a pinion gear tnot.
shown)'which meshes therewith andrigldly connected to the said pinion is sprocket wheel'59.- A chain 60 connects the wheel59 to asprocket' wheel 61 mounted on the handle 55 and, as is obvious, turns the wheel-59 and hence moves the rack58 When thecrank 55 "1 30 is turned. An outlet pipe 62 connects the top of the cylinder 57 to a hose 63. The pipe pistons and means for varying the stroke of 56 also discharges into the said hose.
In operation, the pump 54 is calibrated to deliver a given quantity of gasoline for a predetermined number of rotations of the crank 55, and at the same time a certain quantity of oil is delivered from the cylinder 57. In this construction, the quantity of oil to be mixed is predetermined and poured into the cylinder 57 and, as, the gasoline ispuinped,
the oil contained in the oil cylinder is delivered to and intimately mixed with the gasoline. This latterdevice is adapted for small installations and is readily detachable from the pump 54 proper.
It is apparent that I have provided a novel means and method for readily and eificiently mixing various quantities of oil with a given quantity of gasoline at the same time and by the operation which removesthe liquids from storage. The device itself is comparatively economical to construct and will fill a long felt want. Incidentally, the quantity of gasoline and oil consumed by engines of the type requiring mixed fuels comprises approximately 15,000,000 gallons of gasoline and 3,100,000 gallons of motor oil annually.
I am aware that many modifications may be made and many details of construction altered without departing from the spirit of the invention, and hence I do not wish to limit myself to the specific structure shown.
By this dual pumping combination, it is possible to give to outboardmotor engine users a device which will give them the correct proportion for grade of gasoline desired with the proper proportion andgrade of motor oil thoroughly mixed, so that when they get an outboard motor fuel from such a pump combination, a great deal of the trouble now being experienced will be eliminated. At the same time, it will avoid the prohibitive expense of containers when such a mixture is put up by the oil company shipped to the pointof use and in addition thereto, will give a fresh mixture to the user, which is more desirable. I
In conclusion, it appears that through experiments and cooperation with certain of the manufacturing companies, a fuel compound of gasoline and oilhas been worked out which has completely cured some of the most pernicious and harmful ills of the outboard type of motor or any other two cycle type lubricated by placing oil in the fuel. The troubles that have been eliminated are, roughly: uneven power development, difficult starting, poor fuel economy. With these features corrected, more revolutions per minute and more power is naturally obtained.
I claim as my invention:
1. A combination pump'for simultaneous- 1y dispensing and mixing fluids, comprising a plurality of cylinders having a common discharge outlet, a corresponding plurality of pistons, common means for operating said mixing fluids, comprising a plurality of cylinders,a corresponding plurality of pistons, means for varying the stroke of one piston with respectto the other, said means including a piston rod associated with each piston, a rack formed at the end of each piston. rod,
