Specification of Letters Patent.
Application led May 23, 1908. Serial No. 434,645.
To all whom 'Lt may concern:
Be it known that I, ALFRED Wns'rMAooT'r, a subject of the King of Great Britain, residing at St. Helens, in the Isle of Vight, in the county of Hants, England, naval architect, have invented certain new and useful Improvements in or Connected with Carbureters and Vaporizers for InternaL Combustion Engines, of which the following is a specification, reference being had to the drawings hereunto annexed and to the figures and letters marked thereon-that is to say:
The invention relates to improvements upon an inventionv inV respect of which Letters Patent No. 800777 issued 3rd October 1905l the purpose of which was primarily to provide a means of utilizing paraiin oil in the production of an exploslve mixture and the object of the present invention is to improve various details of construction Iof the subject matter of said Letters Patent.
In the accompanying drawings Figure 1 is a side elevation of a carbureter and vaporizer for internal combustion engines constructed according to the present invention. Fig. 2 is a plan thereof. Fig. 3 is a vertical transverse section taken on the line 1 1 of Fig. 1. Fig. 4 is a sectional detail view, the section being taken on the line 1 1 of Fig.
y 1, of the throttle valv'e levers and some connected parts. Fig. 5 is a vertical transverse section taken on the line 2 2 of Fig. 4.
Fig. 6 is a plan partly in section of F 1g. 4 with slight additions the part in section being taken on the line 3 3 of Fig. 3. Fig. 7
is a similar view to Fig. 3 of the mixing valve with its seating. Fig. 8 is a plan of the mixing valve separately. Fig. 9 is a plan of the expansion ring separately. Fig. 10 is a transverse section taken on the line 4 4 of Fig. 9. Fig. 11 is a side elevation of' a carbureter and vaporizer illustrating tlie employment of one auxiliary air valve. Fig. 12 is a plan thereof and Fig. 13 is a part vertical transverse section taken on the line 5 5 of Fig. 12.
In the several figures like parts are indicated by similar letters of reference and Figs. 7 and 8 are drawn to an increased scale with respect to the other figures of the drawings. y
Referring to Figs. 1 to 10 a represents a case or chamber within which is removably fitted lon 'tudinally of the case a, a cluster oftubes constituting a vaporizer which tubes at their ends are fixed in tube plates b1 b2, the lower one b1 of which has a beveled or coned peripheral edge b1* which ts against a corresponding shoulder or seat a1 upon the interior of the case or chamber a.
The tube plate b2 at the upper ends of the tubes b is formed with a plain or cylindrical periphery which closely fits the case a and in order to enable a tight joint'to be made between these parts and to provide for the expansion of the tubes under the inuence of heat, which provision has been found to be necessary in practice, and at the same time to hold the cluster of tubes securely in place with capability of easy removal the following arrangement of parts is employed.
A skeleton support or spider c is exteriorly of its peripheral ring c1, threaded, and said ring is screwed into a corresponding thread Patente@ Nov. es, aero.
formed upon the Wall of the case a beneath e the lower tube plate b1 and the central boss c2 of this spider is bored and threaded to form a nut while above the upper tube plate b2 is arranged another spider or skeleton frame b3 which is formed with a peripheral ring b* and said spider is of dished formation so that said ring b4 bears upon the upper tube plate b2 at its edge and also against the case a.
Passing through a central or distance tube is a spindle b5 which near its lower end is formed with a shoulder be which bears upon the lower tube plate b1, and the reduced end 117 of the spindle b5 is threaded to receive a` The upper end of the spindle b5 is thread' ed and passes through a' perforation in the boss of the spider b3, and immediately above the upper tube plate b2 it is provided with a nut b9 Which screws down u on the tube plate and makes a gas tight jolnt, and a nut .blo is screwed upon said threaded upper end and bears upon the boss of the spider b", and the group of tubes and their tube plates b1 .b2 are thus firmly fastened together with capability of easy removal bodily while the natural spring due to the dished formation o f the spider b3 admits of the natural expansionv and contraction of the tubes b under i `varying temperatures. l
The cluster of tubes b is removably fixed in position in the case a by the threaded lower end of the spindle b5 which screws into the threaded perforation in the central boss (f2 ofthe fixed spider (f while the spindle at its upper end is provided with a square H. to receive a key by which it may be turned.
As in my former specification hereinbefore referred to, an opening a2, closed by a door a3, operated by a handle a3 is provided at the side of the case L for the passage of the flame of a blow lamp in order to effect a preliminary heating of the tubes when starting the apparatus, and the case (L between the tube plates b1 b2 is by a way a* connected with the exhaust port of the engine cylinder so that the hot gases circulate among the tubes b and after the start maintain said tubes at the required temperature-to effectually Vaporize the oil and after circulating among the tubes the products pass away b y the outlet (L5.
The case a above the cluster of tubes b is provided with an outleta connecting with the induction pipe of the engine and controlled by a throttle valve e. Screwing into the lower part of the casing a below the cluster of tubes b is a kind of venav ('(mw/caA (Z provided with a lateral tubular branch (Z1 which is connected by a junction (Z2 with an oil supply and the tubular branch d1 is. fitted with the usual needle valve i adjustable by a hand wheel or disk 1 and automatically operated as hereinafter described for regu lating the supply of oil to the vena ('ontracto d.
The .wena contracte d below its junction with the case a is inclosed in a casing (Z3 open at the top to admit a supply of air through the space (Z4 and the lower part of the reim contracter, is furnished with perforations (Z5 which admit air to the interior thereof while the floor of the casing (l3 is provided with a drainage pipe al for any free oil that may accumulate.
i Seating upon the upper part of the rem( contracte at d* is a conical valve Z7 which normally closes the oil way dt* from the branch d1 but is lifted by the suction stroke of the engine so as to admit a supply of air and oil to the mixing chamber (ik. This valve (Z7 is carried by a spindle d which works, in a long bearing (ZQ carried by the bottom of the casing cl3 and extends to the outside of said casing where it is provided with a spring d10 which acts against a washer supported by a regulating nut (In so that the valve Z7 is constantly forced upon its seat'd* with a pressure capable of regulation. The upper part 7* of the valve Z7 is also formed conical and performs an important function inasmuch as it permits the mixture to be carried cleanly into the tubes b and prevents any objectionable drip caused by the lodgment of the oil due to air eddies and thereby greatly increases the efficiency of the vaporizer.
rlhe head a7 of the case a. consists of a chamber open by a way a8 to the atmosphere and in the fioor of this chamber are provided auxiliary air ways or inlets afJ controlled by inwardly opening valves f earried by the lower ends of rods f1 working in long bearings f2 supported by the' top of the head a7 of the case a and said rods are at their upper ends threaded and provided with nuts f3 and around the rods and their bearings are coiled springs f* which atl their upper ends bear againstthe nuts f3 by which their degree of compression may be regu lated and at their lower ends press upon the spread out extremities f 7** of the arms 7' of a yoke the central boss of which is formed as an oval ring within which is a distance collar f and trunnion pins or studs fg are passed through the ring or boss at-itsnarrowest part and also through the collar fs and at their ends engage the thread o3, hereinafter referred to, so that the screw will act to raise and lower the yoke while the latter is free to rock to a limited extent thereon.
The throttle valve c is carried by an arm e1 fixed with a spindle e2 revolubly working in'a bearing al in the head of the case a and the upper end of the spindle c2 is formed with a quick thread e3 which engages the ends of the studs ff as hereinhefore described, and said parts are. so arranged that the rotation of the spindle e2 to close the throttle valve (z will raise the arms f of the yoke and compress the springs f* and thereby increase the resistance against opening of the auxiliary air valves to the suction of the engine proportionately to the extent to which the throttle et is closed so that the introduction of air at the auxiliary air inlets (i9 is regulated accordingly.
rl`he spindle e? of the throttle'valve e has fixed thereon an arm or lever e* the free end of which carries a swiveling eye e5 through which passes a rod eG provided with a collar e7 and the end of which rod is connected with the engine governor.
The governor rod e has a collar es adjustably lixed thereon and around the rod e", between the collar eS and the eye e5 is coiled a spring e so that upon an increase in speed of the engine the governor rod e is moved toward the right, Fig. G, and by its collar ('7 engages the eye e5 of the lever eI and exercises a thrust thereon and more or less closes the throttle valve e but upon the slowing of the engine the governor rod e is moved in the opposite direction to exercise a thrust upon the eye e7! through the spring e9 thus more or less opening the throttle valve (1. The governor is secured to the left hand end of the rod shown in Figs. 2 and 6.
Mounted loosely upon the spindle c2 of the throttle valve c is a hand lever g which near to its free end is provided on one side thereof with a lug g1 which engages one side of the arm or lever e4 and the' hand lever g works over a quadrant g2 While connected at g3 With the hand lever g by a bolt or rivet is a clamping bar g4 which occupies a position on clamping bar atits `free end is bored and the under side of the quadrant g2 and the tapped 'at g5 to receive the threadedend of a spindle ya furnished with a handwheel gs* and Which spindle is revolubly mounted in a hole bored in the extremity of the hand lever g, coincident with the tapped'hole g5. and is furnished With a flange or collar g7 Which bears upon the hand lever g so that by turning the hand Wheel ge* the hand lever g and clamping bar g4 Will nip or clamp the quadrant g2 between them. The hand lever g may thus be set to any point Within a given arc, as shoWnat-F-ig. 6, so that its lug will by engaging the lever or arm e4' prevent the movement of said lever beyond a given point in the direction required to open the throttle i a reservoir (not shown) and leading from the valve casing is an inclined pipe h4 Which terminates over a cup a from Whi'ch a pipe au leads through the top of the head a7 to a position immediately over one of the valve controlled air inlets a9 in the bottom of the head or chamber a7 and the office of which is to supply a Water drip to the vaporizer for the purpose of preventing premature ignition and heavy knocking in the cylinders When using parafiin in a motor of high cylinder compression.
The needle valve h3 of the Water drip is fitted with a hand Wheel h5 for purpose of setting the valve and upon the inside face of the hand Wheel 71.5 is a ring of serrations h5* and loosely mounted upon the valve spindle is adisk it the face of which is provided With a. ring of serrations4 h6* adapted to coact With the serrations h5* of the hand Wheel 'h5 a spring LX being provided-to keep these parts in contact.
Formed on or fixed with the disk it is a slotted arm or` lever LGl* and adjustably fixed in the slot of the arm h** is a stud with which is connected by a ball and socket joint 71.7 one end of a link ha the other end of which is by a ball and socket joint hg connected with an offset e4* from the arm or lever e4 which as hereinbefore described is connected with the governor rod c so that the governor automatically regulates the Water drip. The hand Wheel '51 of the Ioil feed valve z' upon its face is similarly prowith the lower end of a link or connecting rod t the upper end of Which is by a ball and socket joint 5 connected with a stud adjustably mounted in the slot of a slotted arm s the inner end of which is fixed with one -end of a short shaft 277 mounted in a bearing formed in a bracket al fixed' to the head a7 of the case a and to the other end of the sho-rt shaft l is fixed an arm is the extremity of Which is by a ball and socket jointV 9 connected with one end of a` link 1 theot-her end of which is by a similar joint u connected With the offset et* from the lever e4. By this arrangementthe nor-' mal supply of the Water drip valve h3 and oil supply valvez' may be respectively regulated by the hand Wheels h5 and z and the adjustable studs of the ball and socketjoints k7 and 5 of the slotted arms hw* and i and by reason of the connection of said valves as hereinbefore described With the lever e* which controls .the throttle valve the fuel and Water supplies to the'vaporizer will be. 'automatically lregulated synchronously with the supply of explosive mixture to the eugine.
In the example given at Figs. 11 to 13 is shown a slight modification in which a single auxiliary air valve is employed. In this case a single opening a9 is provided in the head a7 of the device closed by an inwardly opening valve f carried by a rod f1 upon the upper end of which is fixed a collar f1* underl which takes one end y" of a lever f formed with a boss f5 having studs f which engage at e3 the screw ofthe spindle e2 of the throttle valve e similarly to the arrangement previously described. The other end of the lever f6 is forked at f7* and embraces a sleeve provided With a flange f under Which the end f7* of the lever takes and said sleeve slides upon a rod fm fixed With the head a7 of the device and at its upper end is threaded and provided with a regulating nut f3 While between the flange f11 and nut f3 is arranged a spring f4 which tends to keep the valve f up to lts seat. The chamber at the head a7 of the case a is in this example dispensed With and the bracket e113 is carried by the case a. e The action of this device is similar to that hereinbefore 'described.
Although the apparatus is primarily intended for the use of paraflin oil it will bc understood that it may be employed in connection with any light oil or with petrol or other spirit.
