Description
y 1936- A. w. KUSHINSKY FUEL SAVING DEVICE FOR INTERNAL COMBUSTION ENGINES Filed March 10, 1936 1M 'EN TOR. Arfbur W. Kusbinskx m Patented July 7, 1936 PATENT om-cs Among the objects of my invention are to create an automatic, attachable device adapted; to be added to any internal combustion engine for saying fuel consumption, which combines the feature of saving gas when the 'opera'torftakes his foot ofi the accelerator with the added feature of saving gas during high speeds, and such other objects, advantag'es and capabilities later more fully appear and which are inherently possessed by my invention' I While I have snowam' the accompanying drawing a preferred embodiment of 'myin'vention yet I wish it understood that the'sam'e is susceptible of modification and chase Without departing from the spirit of my invention;
Referring more particularly to the drawing: Fig. 1 is a diagrammatic figure-showing my invention mounted in pl'a'ceori an automobile engine and the electrical circuit shown thereon; Fig. 2
is a longitudinal cro-ss-sectio'n'pf mylinvention;
and Fig. 3 is a plan'section takeri onthe line 3'-3 of Fig. 2. 4 v
As stated in my BatentNumber 2,035,237'01 March 24, 1936, in Fig. 1 I show the floor boards l8 and the cowl ll through which passes the clutch pedal l2 of an ordinary automobile. Pref erably underneath the floor boards of the caris located a battery l3 having a wire"l4"grou'n'ded to the frame of the car at l5. At the opposite side of the battery l3 awire l6 leads contact springs I! which are fixed to the floor boards 10 by suitable means such as bolts*l8"a;nd insulated therefrom. The contact springs I! are closed when the clutch pedal I2 is in clutch engaged position. Leading from the contact springs I! is another wire I9 leading to second contact springs 20, which springs are fixed by suitable fastening means 2| to a bracket which is attached to the carburetor bolt 22 and insulated therefrom. When the accelerator rod 23 is in released position the contacts of contact springs 20 are closed by the adjustable stop 24 on accelerator rod 23. Leading from contact springs 20 a wire 25 leads to one side of the solenoid winding 26 so that electrical current may pass through the winding of said solenoid 21 to the other side 28 of the solenoid to locking contact spring 29, said locking contact spring being insulated by suitable insulating material, and from looking contact spring 29 to wire 38 which leads to contact screw 3 I, whch is suitably insulated from vacuum unit 33. When a high vacuum is created in the manifold 32 the vacuum unit 33 is operated making contact at 3| which completes the circuit, (vacuum unit 33 is grounded to the motor, and
the motor isgi'ounded to the framel alleging the solenoid 2"! which 7 operates the plunger f 34 raisin'g'the same so that looking spring 29 makes contact on a washer or thelike'34d of said plunger 34 to establish a secondary circuit locking the solenoid in the operated position. v, This invention differs from my Patent No. 2,035,237 of March 24,1936, in that a bolt 35 is fixed into the plunger34', has a protruding head 36, and extends downwardly below the bottom of said plunger 34, and travels within the collar valve stem 56 of thevalve 38. When the-plunger 34 travels upwardly the bolt 36 likewise travels upwardly within the valvestem of the valve 38 as far as stop member59 to expose opening 39. Within the hollowed out stem 56 of valve 38 lies movable piston 52. A resilient member such as a spiral spring 53 has its upper end contacting the piston 52 and its lower' end held by shoulder 51 of the'st'em"56; The valve 38 at its head portion 58 has'an' opening'55 and from the stem portion 56 another opening 54; The opening 55 leads to the manifold chamber 40, and the opening 54leads to the atmosphere. 7
As previously stated-in my Patent No. 2,035,237 of March 24, 1936, in use let usassume that the driver is using a speed of some 30 miles per hour manifold and hence'into the motor which would result in great waste. In' my s'tr'ucture instead plunger 34 and the valve 38 to permit air coming in through ports 4| into my chamber 4!) connect-- ing with the manifold. In use it is also apparent that. as soon as the foot of the operator again moves to accelerate the car the contact springs 20 will be automatically opened and the circuit to the solenoid 21 will be broken restoring valve 38 to normal closed position, whereupon gas will be fed from the carburetor to the motor. On the other hand as an added safety feature, if the operator does not press the accelerator pedal, or change the clutch position from that shown in Fig. 1, air continues to be drawn into the motor, so that'in time it will die. This is important where the operator is suddenly incapacitated, and willresult in saving of life and property.
It will be further noted that the vacuum unit 33 is preferably encased for protection in keeping contacts clean and workable.
7 comprises a plate 43 secured to coupling 44 by 'ber 40.'-,
means of screws 45 and having at its outer end a ring 46 suitably secured thereto, and housing or, cover member 41 which will slip over said ring 46. In the wallof said housing 41 is a slot 48 toslipover hollow nipple 49 and the coupling 44 is screw threaded for engagement, and the coupling 44 has a port 50 in communication with the chamber 40. Vacuum tube of. vacuum unit 33 is secured to the'outer end of nipple 49 by means of solder or the like.
7 'This] invention diifers from my'Patent 'N o. 2,035,237 'of March 24, 1936, in that in non -op erated'position piston 52 is held up by springst 53 against screw head 35 which acts as a stop' member exposing hole 54. 'When the motor is operatedpiston 52 is drawn-down by the vacuum, closeshole 54and thus prevents the admission of air. ,Thus at constant load when the motor is running at high speed-the vacuum in the maulfold will decrease. This will allow spring 53 smallerthan port 55 softhat spring 53 acting on piston 52 may be-drawn down by suction in cham- Having thus describedrmy invention I claim: 1. In combination with aninternal combustion engine and an electrical source of supply, afuel saving device adapted to be attached to the manifold of said internal combustion engine comprising an air intake structure having a plurality of "air'inlet ports and a'chamber communicating with said manifold, said chamber having an opening, a valve with valve stem controlling said ;opening, means including a'plunger adapted to move said valve to close said opening when'the "accelerator of theinternal combustion engine is actuated, and to expose said opening whenthe accelerator is released, including a solenoid op:-
' eratively connected with said plunger, an electric circuit adapted to energize said soleno'id, and a vacuum unit adapted upon the creation of a high Said casing 42 vacuum caused by the release of the accelerator to contact said solenoid to instantly actuate said plungerfto open the valve until pressure againapplied to the accelerator breaks, the circuit and returns the valve to closed position, said valve having a 'casing'withan upper opening adjacent f its stern portion leading'to the atmosphere and a. lower opening adjacent its head portion leading to the manifold, a piston movable within. the
upper'part of said stem portion of the valve, a I
resilient member withinthe lower part of said stern portion of the valve and having its upper end-contacting the piston and its lower end held bya shoulder of the head portion of the .valve,
said piston norrn'allypositioned by said, resilient 'member when the engine is not running to'exposethe upper opening for admitting air but said pistionadapted to be pulled downwardly by vacuum when the engine'fis running to close said upper opening, said'resilie nt member having tension sufficient. to push'said piston upwardly as the vacuum is decreased by the increased speed of the running engine so as: to. expose said upper openingin proportion to the. increased speed for admitting. air into the valvef'casing and thence I through the lower opening into the manifold.
2. In afuel saving device adapted to be attached to the manifold of an internal combustion 4 engine, a valve and valve stem having a casing withan upper opening, adjacent its stem portion leading to the atmosphere and a lower opening adjacent its-head portion leading to the manifold,
a piston movable within the, upper. part of said stem portion of the 'valve, a resilient member.
