UNITED STATES RENE CHARLES WATTELLIER, OF SAMOIS-SUR-SEINE, FRANCE. i

. FUEL ECONOMIZER FOB EXPLOSION ENGINES.

Application tiled June 8,

- To all whom it may 00mm.-

Be it known that I, Rem: CHARLES WAT- TELLIER, citizen of the French Republic, residing at Samois-sur-Seine, Seine and Marne, in theiRepublic of France, have invented new and useful Improvements in Fuel Economizersfor Explosion Engines, of which the following is a specification."

This invention relates to afuel economizer for explosion engines, by means of which an amount of air may be automatically introduced into the intake'pipe of the engine at a point between the throttle and the admission valve at the same time as thethrottle is opened and in proportion to the extent of the opening movement of the latter, whereby a better utilization of the charge is obtained and consequently an economy is realized in the fuel consumption of the carburetter.

A characteristic feature of this economizer resides in that it comprises a casing adapted to be mounted on the intake pipe of the engine at a point between the throttle and the admission valve, said casing being provided with an air passage which is controlled by a rotatable disc plate provided with a port and connected by a flexible transmission to a member controlling the throttle.

Other features of the invention will appear from the following description.

In the accompanying drawings given by we. of example:

liig. 1 is a section through the axis of the fuel economizer constructed in accordance with the present invention.

Fig. 2 is a plan view of the same, the carburetter being removed.

Fig. 3 is a plan view.

Fig. 4.- shows the apparatus mounted on the intake pipe of an engine.

Fig. 5 is an axial section corresponding to Fig. 1 and showing a modified construction.

Fig. 6 is a diagrammatic view of the economizer together with the controlling members for the same.

As shown in Figs, 1 to 4, the apparatus comprises a casing 1 provided with a screwthread'ed tubular rojection 5 by means of which it is secured to a neck 6 (Fig. 4) providedon the intake pipe 7 of the engine at a point between the throttle 23 and the admission valve not'shown. A nut 8 ensures the fixation. The bottom wall 4 of 1921. Serial No. 475,931.

the casing is provided with a hole 5 which extends through the tubular projection 5 and through which the air will pass into the intake pipe 7. The casing 1 is provided with a flat recess 9 in which a disc plate or obturator 2 is rotatably supported. The bottom wall of said recess 9 maybe provided with shallow arcuate recesses 10. Upon the casing, is secured by means of screws 11, a cover 12 provided with holes 13 for the inlet of air and carrying a boss 14 in which the end of a flexible transmission 15 is guided.

The disc plate 2 is mounted on a central screw or pivot 16 supported by the bottom 4 of the casing. Through the disc plate extends an oblong or wedge-shaped, designed opening 17 (Fig. 2) which is adapted to register with a hole 5 of the casingwhen the plate 2 is oscillated, and will coincide with said hole in the opened position of the apparatus. The disc plate is carefully dressed in order to ensure a tight joint and it is constantly urged to its closing position by a spring blade 18 secured to an arm 19 which is itself secured to the disc plate, said spring blade bearing upon a stud 20 secured to the cover '12. A'yielding spider 21, with four branches, held by the screws 11 bears, at'its central part, upon the head of the central screw 16, and holds the disc plate '2 in contact with the bottom of the casing 1. To the lever 19, is secured the controlling flexible wire within the tube 15,

said wire being connected at its other end to the lever 22 (Fig. 4.) operating the throttle 23 .of the 'carburetter. The lever 19 moves ina notch formed in the upper edge 24 oi the casing.

A supporting'yoke 3 secured to the easing 1 carries an oscillating lever 25 by means of which the-lever 19 may be locked in the closing position of the disc plate; said lever is actuated by means of a flexible wire within the tube 26, said wire being secured to tle 23 through the medium of the flexible cable 15 and thelever 1 9, is turned in the passage 5 of the casing 1, whereby an amount of air is introduced into the intake pipe in proportion, as the passage 5 is un covered and the throttle 23 is opened.

In the modified construction shown in Figs.v 5 and 6, the casingaof the economizer is closed by a plate 05 carrying a screwthreaded tubular projection d through which a passage j extends. Said projection carries a nut e and a washer f and is used as in the above construction for the purpose of securing the apparatus upon the intake pipeof the engine.

Upon the bottom plate d of the casing, is rotatably mounted the rotatable disc plate or obturator it which is carefully dressed and pressed upon the plate 05 by a coil spring g.

The disc plate It is provided with an oblong opening m which may coincide with the circular passa e -j. It is" actuated by a flexible cable is whlch passes through a guide 01. and is connected to the accelerator or other member controlling'the throttle of the en-;;,

gine. A. spiral spring 21 tends to bring the disc plate It to its closing position. By

means of said arrangement, an additional whereby theangular position of the discv plate 72. in the casing may be variedat any instant, so as to change the amount of air drawn in, independently of the action of the member controlling the throttle. F or this purpose, the operating cable is passes around a uide pulley 0 having a fixed axis and a ti tening pulley Z. The pulley Z is carrie by a yoke member I) which is pivoted on the shaft of the pulley c. The yoke b may be angularl displaced in the direction of the arrow Fig. 6) by means of a flexible cable p operated by a handle 9 secured either to the steering wheel or to the dash board of the vehicle. The pulley '1 can thus be bodily displaced around the axis of the pulley c. It will thus act to tighten the cable is, whereby a rota-r movement will be imparted to the disc p ate h. By this means, the passage ofl'ered to the air through the hole j and the opening m when the cable 7c is pulled will be increased. The opening m has such dimensions that the operation of the engine will be rendered most flexible an amount of air proportional to the charge drawn in'being introduced for each speed of the engine. By means of the handle 9 and whatever the working conditions of the engine may be, the driver is thus enabled to 1,eee,sei

the apparatus continuing to act thereafter automatically. Means are thus provided for adjusting the amount of air necessary to the engine in an instantaneous and easy manner.

It will be seen that the purpose of the apparatus is to obtain an economy of fuel and also to increase the flexibility and power of the engine. In addition thereto it enables to use with the same en ine difl'erent fuels such as gasoline, benzo para or spirit, an instantaneous adjustment being possible. 4

The invention is not limited of course to the constructive arrangements shown or described. F or instance, the tightening pulley Z might be replaced by any other suitable tightening device.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A fuel economizer for explosion engines comprising a casin an eccentrical tubular projection on sai casing adapted to be securedtothe intake pipe of the engine and connecting the capacity of the easmg to the said intake pipe, means for admittin outer air into said casing, a rotatable disc p ate-in the casing provided with a port registering with the inlet of said tubular projection, a flexible transmission for operatively connectin said disc Plate to a member controlling t e throttle of the engine and means for producing a bend in said flexible transmission and thereby displace angularly the disc plate independently of the action of the throttle valve actuating member.

2A fuel economizer for explosion engines comprising a casin an eccentrical tubular projection on sai casing adapted to be secured to the intake pipe of the engine and connecting the capacity of the casing to the said intake pipe, means for admitting outer air into said casing, a rotable disc plate in the casing provided with a port registering with the inlet of said tubular projection, a flexible transmission for operatively connecting said disc plate to a'member controllin the throttle of the engine, a guide pul ey for said flexible transmission,a stationary shaft for said guide pulle', a yoke pivotally mounted on said sha t, a second guide pulley carried by said yoke and means for displacing the yoke angu larly so as to stretch the flexible transmission and angularl displace the said disc plate inde endent y of the action of the throttle va ve actuating means.

in testimony whereof I have signed my" name to this specification.
