- fuel to internal combustion motors of the high compression type.

More specifically the invention relatesto fuel feeding mechanism for multiple cylinder high compression internal combustlon "motors, and it comprises a plurality of fuel pumps, each having an independent govern ing-valve, and an additional valve for positively varying the supply to the governor. The invention may be further briefly summarized as consisting in the constructlon and combination of parts hereinafter set forth in the following description, drawlngs and claims. 1

Referring to the drawings, F gure l s a side elevation of an engine of the type utilizing this device; Fig. 2 is a front elevation partly in section showingthe'fueh feed ng device; Fig. 3 is a sectional view; F1g. 4 1s a bottom plan view; Fig. 5 is a deta l VIQW Of a form of governorwhich may be used w1th the device; Fig. 6 is a sectional view of the type of primary fuel and air mixing valve utilized with the device and Fig. 7 is a detail view of the clamping screw of \the governor hand lever.

In carrying out the inventlon any preferred form and construction of engine and parts may be employed, but I have shown one arrangement which is effectlve, and 1n such embodiment 1 represents a suitable crank case having mounted on it a plurality of cylinders 2 each of which is provided with suitable exhaust manifold and valve mechanism and suitable air inlet mechanism for the auxiliary air supplied to the englne,

the details of these features being of no particular importance; Each of the cylinders is also provided, preferably at its head,

with a suitable primary fuel and air mixing valve structure, and this structure consists of a casing 3 having a centrally disposed mixing opening 4 terminating at the lower end in a valve seat 5 within the cylinder. A

suitable guiding flange 6 projects into the openlng 4 and serves to guide a valve stem \havmg suitable longitudinal openings 8 adJacent to the flange to permit the passage of the mixture of air and fuel. Near 'the 7 upper end of the casing 3 and outside of the cyl nder is a connection 9 connected by a port it) w1th a longitudinally disposed port 11 which-communicates by a port 12 with ,the opening 4. These ports serve to supply the fuel. The casing 3 is also provided outsideof the cylinder with a connection. 13 provided with a port 14.- extending directly into the opening 4 and arranged to supply air under pressure at a point removed from the fuel inlet. The valve '7 is provided immediately above the flange 6 with a plurality of washers 15 having lugs-16 and varying alternately in their inner and outer peripheral dimensions so as to produce a circuitous passage for the mixture of air'and fuel in effecting the mixture. These 'w-ashers extend to a point near the port 12, and

from this point to the upper end of the casing the stem is provided with a sleeve 17 less in diameter than thebore of the opening 4 to a point near the top of the port 14 so as to permit thepassage of the air down-- ward to the mixing portion of the valve mechanism. The upper end of this sleeve. is enlarged at 18 to fit the bore of the casing,

'- 22 keyed to the shaft by a uitable key 23 and having alaterally extending flange 24 forming the bottom of the, governor casing. This hub 22 extends loosely through an opening in the upper end of the casing '21 and rotates therein. The hub is provided and provided with a suitable gland portion 19 coiiperatmg with a'stufling box structure with anannular recess or depression 25 for receiving an opening 25 for a purpose to be described. The flange 24 rests upon a thrust bearing race 26 engaging thrust bearing balls 27 which in turn engage another race 28 arranged upon the upper end of the casing 21. This thrust bearing supports the governor mechanism and also takes the thrust .of the springs therein, as will later sleeve extends upward and is provided with an annular groove 34 upon the outside to I receive the yoke of a governor lever 35'pivotedupon a pin-36 secured to a stationary part. The opening in the sleeve 33 is enlarged to form an annular opening 37 around the shaft 20 in-which is arranged a coil spring 38, this spring bearing agalnst-a shoulder 39 formed within the sleeve and against a thrust sleeve 40 slidably mounted upon the shaft 20. The upper end of the sleeve 40 engages a thrust bearing structure 41 arranged between it and a shouldered control lever collar 42, this collar being loose upon the shaft 20. The shoulder of this collar is adapted to be engaged by a lever arm 43 pivoted upon a shaft 44 secured in a bracket 45 mounted upon the engine. This shaft 44 is operated by a hand lever 46 provided with a concentric slot 47 adapted to receive a pin 48 carried by a bracket 49 secured to the bracket 45. The bracket 45 is provided with a bearing 50 engaging the upper end of the'shaft 20. The pin 48 is threaded on its outer end and is provided with a clamping hand screw 51 adapted to clamp the han lever 46 in any adjusted position. The governor balls, and the mechanism thereabout, is incased in a suitable casing 52 supported by a flange 53 engaging the flange 24. The governor lever 35 is connected, as will later appear, to the fuel feeding mechanism.

The fuel feeding mechanism will now be described. Mounted in some convenient place on the engine is a housing 54 provided with an eccentric shaft 55, shown in dotted lines in Fig. 2 and in full lines-in Fig. 3, and this shaft is provided through out its length with a plurality of eccentrics 56, one for each cylinder, and each of these eccentrics engages within an eccentric strap 5-7 having ears 58.- Theshaft 55 is also provided within the housing. with a gear 59 engaging a driving gear 60 mounted upon a cam shaft 61 supported by the engine and driven from any rotating part. The ear 58 of each of the eccentric straps is provided with a pin 62 passing through an eye 63 arranged in the upper end of-a pump plunger 64 which passes through a suitable stuffing box structure 65 into a pump barrel 66 preferably formed in the housing. Each of these pump barrels is in direct communication with a horizontal 'port 67 in turn communicating with a discharge port 68 leadin to a check valve structure 69 arrange in the housing. This check valve structure communicates with a check valve tructure-70 in a block 71 and a like structure in a block 72 which in turn is in communication with a discharge block 73 pro vided with an outlet 74. These blocks are held in place by suitable cap screws 75. The

port 67 is also in communication with a governor block 76 having therein a check valve structure 77 communicating with a governor valve chamber 78 which is provided with a.valve seat 79 arranged between this chamber 78 and the supply port 80 in the block 76. Slidably mounted within the block is a governor valve stem 81 having a tapered valve 82 at its end 006 crating with the seat 79. A suitable stu ng box structure 83 is arranged about this valve stem to prevent leakage at this point. Communicating with the inlet opening 80 is an opening 84 arranged in an inlet check valve 86. This opening 84 communicates with a check valve opening 87 in an individual control block'88, this opening communicating by means of avalve seat 89 with a general supply port 90. This valve seat is adapted to be engaged by a. needle valve 91 having a threaded shank 92 engaging in the individual control block 88. A suitable stufiing box structure 93' is arranged about this stem and the end of the stem is provided with a hand wheel 94. All of these inlet parts are secured to the housing by means of cap screws 95. There is a com lete discharge check valve structure and in ct structure including the governor valve and the individual control valve for each of the cylinders and for each of the eccentrics, and the governor valves are controlled as a gang, as will now be described.

Each of the governor valves 81 is threaded at 96 through a bar 97 and held in any adjusted position in said bar b means of check nuts 98 and 99. This bar 9 is rovided with trunnions 100 at each an as shown in Fig. 2, and each of these trunnions engages in a bearing 101 formed on the endof an arm 102, the other end of the arm having a'bearing 103 engaging an eccentric formi a part of the shaft 105 supported in bearm 106 secured to the rear of the block 76. T is shaft 105 is adapted to be rocked by a crank arm 107 connected to a link 108 in turn pivotally connected to the governor lever 35 of the governor.

1 Assuming that the engine is at rest, and that the operator has previously moved the hand lever 46 to the left, releasing the spring 38, so that the spring 25' is free to raise the sleeve 33 and throw the governor balls outward, then to start the engine the hand lever 46 is grasped and tension for adjusting each valve in said bar, and

brought to bear upon the spring 38, thus moving the governor into starting position, with the result that the governing valves have been moved outward to the proper point of starting. The starting mechanism, not shown, for the engine is then set in operation, and rotation is set up. As soon as the engine is operating under its own power, when the .fuel pumps will be throwing the proper amount of fuel, controlled by the governing Valves and the hand valves, the governor then regulates this control and serves to supply the proper amount of fuel to each cylinder. It is obvious that the control of each governing valve may be ad-' justed and that each individual supply to thegoverning valve may be adjusted throughthe hand operated valves 91.

Having described my invention, I claim 1. Fuel pump mechanism for internal combustion motors comprising a plurality of fuel pumps, a discharge for each pump, an inlet for each pump, an inlet valve, a governing valve for each pump, a bar connecting all of said governmg valves, means mechanism for movingsaid bar.

2 Fuel pump mechanism for internal combustion motors comprising a plurality of fuel pumps, a discharge for each pump, an inlet for each pump, an inlet valve, a governing valve for each pump, a bar for connecting all of said governing valves, means for adjusting each valve in said bar, and mechanism for moving said bar, com.- prising a shaft rotatably mounted, eccentric members carried by said shaft, links connecting said eccentrics and said' bar, and means for actuating said shaft.

3. In combination with an internal combustion motor, a governor, a series of fuel feeding pumps for the cylinders of said motor, a series of valves connected in a gang and operated by said governor as a unit for regulating the fuel fed to said pumps in accordance with the speed, and additional means for individually adjusting the fuel upply to each pump.

In testimony whereof I afiix my signature in presence of two witnesses.

ALEXANDER WINTON.
