HENRI MAURICE PIPLU, OF PARIS, FRANCE.

CARBURETER.

Specification of Letters Patent.

Patented Nov. e, 1910.

Application filed March 29, 1909. Serial No. 486,558.

To all whom 'it may concern:

Be it known that I, HENRI MAURICE PIPLU, a citizen of the French Republic, and resident of Paris, France, have invented certain new and useful Improvements in Carbureters, of which the following is a specication.

This invention relates to improvements in carbureters of that type in which carbureted air is produced in accordance with and controlled by consumption thereof.

One of the features of my invention consists in providing a regulating device for the oil through which the same flows by gravity into the carbureter and which is controlled by mechanism for supplying the air to the carbureter so as to supply oil thereto in predetermined quantities proportioned to the supply of air and wherein the supply of air and oil are both controlled by consumption of the carbureted air.

The invention will be more fully described in connection with the accompanying draw ings and will be more particularly pointed out in and by the appended claims.

In the drawings Figure 1 is a View partly in section and partly in elevation showing the controlling device for the oil in connection with one form of carbureter and also showing a portion of the air supplying,` means operatively connected with the oil controlling device to operate the same. Fig. 2 is a vertical sectional view on line 2 2 of Fig. l. Fig. 3 is a sectional View of the modified form of carbureter. Fig. 4 is a view partly in elevation and partly in section of a complete apparatus embodying my invention. Fig. 5 is a vertical sectional view of Fig. 4 with the oil controlling device and carbureter omitted. Fig. 6 is a sectional view of the device shown in Fig. 5.

Like characters of reference designate similar parts throughout the different tigures of the drawings.

First referring to Figs. 4, 5, and 6, the mechanism for supplying air is shown as consisting of a casing 38 adapted to contain a body of liquid 39 and provided with a closable opening 40 through which the casing may be filled. An air outlet 41 is provided for said casing and is connected by a pipe 23 with the carbureters 33. Within the casing 38 a shaft 42 is provided, which eX- tends through a suitable stuling boX 43, and on which shaft a drum or rotor 44 is mount ed. This drum or rotor, and the parts with which it is associated may conveniently be termed a pump, and the rotor is provided with a plurality of partitions 45 forming air buckets. At one end of -the rotor a chamber 46 is provided into which an air inlet 47 projects. Said air inlet may, if desired, be provided with a non-return valve not shown, and also a vertical extension 48, extending above the level of the liquid 39. When the drum or rotor 44 is rotated airis drawn in through 48 in the direction of the arrows and is forced outwardly into the casing above the level of the liquid at 49 and is discharged through pipe 23 into the carbureter 33.

A convenient means for operating the rotor 44 may consist of a train of gears 50 connecting the shaft 42 with a windlass or rope drum 51 about which one end of a rope 52 is trained. As shown said rope 52 extends over a pulley 53 and laterally over a second pulley 54 and downwardly over an idler 55 and upwardly therefrom where it is fixed to a ring 56. A suitable weight 57 is suspend'- ed from the idler and serves to actuate the drum 51. At one end of the drum 5l a gear 58 is mounted and meshes with a gear 59 having a shaft 60 to which a wrench or like implement, not shown, may be applied to wind the rope 52 about the drum 51 and raise the weight 57 to a starting position. A suitable pawl and ratchet device 61 may be interposed in the gearing 50 so that when said rope is wound up the rotor 44 will not be actuated.

The carbureter 33 may consist of a casing provided with suitable partitions or diaphragms 34 affording a circuitous path for the air in its passage therethrough and as shown said carbureter has an inlet at the connection of pipe 23 therewith and an outlet through pipe 35. Pipe 35 forms the consumption or supply pipe leading to the jet or other points of consumption not shown. Reference will next be made to t-he oil controlling device whereby oil is admitted to 7 interposed between said cylinders 5 and 6V and provided with adjustable means therein for controlling admission from cylinder 5 to cylinder 6. As shown cylinder 5 is connected with a source of supply of oil 62 by means of pipe 15 and the arrangement is such that the supply is fed by gravity. In order to exclude air from the cylinder or chamber 5 one end thereof is sealed by a diaphragm 10 which is interposed between a seat formed on said cylinder and a ring 11 conveniently forming a part of the valve stem guide or frame 12. The chamber 5 is provided with an outlet 5, preferably at its bottom, and the outlet is flared at 52 to form a seat for a valve 8. The valve 8 is provided with a valve stem 9 which extends upwardly through the diaphragm 10 and the latter may be secured thereto in any desirable manner such as by the nuts shown. It will be seen that by this arrangement movement Vof the valve 8 can be effected and the chamber 5 will always be closed by the diaphragm 10. The valve stem 9 pro-jects upwardly to a bore 14 in t-he frame 12 and is guided by a cap 13 secured to the top of the frame 12. The bore 14 is preferably enlarged with respect to the stem 9 so as to provide fora spring which is interposed between the cap 13 and the nuts heretofore referred to. The spring serves to normally seat the valve 8 and close the outlet 5. An arm 31 on the frame 12 forms a pivotal bearing for an operating lever 3 which is connected with the valve stem 9 and is operated in a manner which4 will hereinafter be more fully described. The chamber 5 delivers to said second or intermediate cylinder or chamber 7 having a piston 25 provided with a' threaded stem 26 for adjusting the capacity of said chamber. rI`he stem 26 is grooved longitudinally to receive a set screw 30 to prevent rotation of the stem 26 and piston 25. Anut 27 has threaded connection with the stem 26 and is rotatively mounted in the cylinder 7 as shown and is held in place therein by a cap 7 A hand wheel 29 is fixed on the nut 27 by a screw 28 and when the hand wheel 29 is turned longitudinally adjusting movement is imparted to the piston 25.

The outlet or delivery casing or cylinder 6 is provided withran inlet 6 having a flared seat for receiving the valve 16. The valve 16 is provided with a valve stem 17 and the casing or chamber 6 is closed at its outer end by a diaphragm 18. VIhe diaphragm 18 is is interposed between the cap 21 and one of the nuts hereinbefore described to normally hold the valve 16 in a closed or seated position. An arm is formed on the frame 22 and a lever 4 is pivoted to said arm' and is connected with the valve stem 17 for operating the same as will hereinafter be more fully set forth. The outlet or delivery casing 6 is connected with the carbureter 33 by a valve connection 24 to deliver the oil to the upper portion of the carbureter and permit it to How downwardly in a tortuous path and intermingle with the upwardly flowing currents of air.

In the specific construction shown the oil controlling device is driven from the air supplying mechanism or pump by providing on the shaft 42 a disk 1, having a plurality of pins or equivalent parts 3 spaced at equal distances apart from each other on said disk'. The levers 3 and 4 are so disposed as to bring their free ends into the path of movement of said pins 2 and the arrangement is such that the levers 3 and 4 will be sequentially actuated first to open valve 8 and sebsequently open valve 16` it being clear from the foregoing description that the springs close the v valve immediately after the pins 2 pass from engagement therewith.

It will be seen fromrthe foregoing that the oil has flowed by gravity from the source of supply 62 until it reaches the carbureter 33 and by this arrangement I thereby avoid the provision of pumps and the like for ad-` vancing the oil thro-ugh its course.

It will be further noted that in operation oil is only admitted to the carbureter 33 when consumption of the carbureted air is taking place and that the admission of oil is such that the quantities admitted will" always be completely taken up by the in limit the passage of oil from the intake chamber 5 to the delivery chamber 6 in proportion according to the requirements of conditions under which the apparatus is operating. The provision and operation of the inlet and outlet valves 8 and 16 provides j for regulating the passage of oil, and mecha; 65

` nism for supplying air to said carburetor and operatively connected with said valves.

an effective intermittent speed and insures an economical utilization of the o1l and the closing of the chambers 5 and 6 amply protects the oil until it has reached the carbureter.

In the modified construction shown in Fig.

3 the partitions 37 are spirally formed about g a body 36 and extend from the intake 23 to L the outlet 35.
