CHARGE-FGRMING DEVICE FOR INTERNAL-COKBUS'ION ENGINES.
SpecicationA of Letters Patent.
Patented Dec. 3, 1907.
Application filed April 5, 1907. Serial No. 366,508-
. D Qviccs for Internal-Combustion Engines, of
which the following is a specication.
This inventionis a charge forming device for internal combustion engines, and it includes a pump, a carbureter or mixing chamber and an auxiliary air valve; as well as associ'atedparts to be' hereinafter more particularly described.'
An ,especial feature of the pump is that it will deliver an exact amount of the fuel at @each stroke, and does not depend upon suction in the mixing chamber, or other uncertain` means, but will deliver a positive amount, which'however may be varied byadjusting devices to. be described.
T he invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the device. Fig.f 2 is. a central vertical section with the pump plunger in lowered position. Fig. 3 is a similar view with the pump plunger lifted. Fig-t is a vertical section at right angles to Figs; 2 and 3.` Fig. 5 is a horizontal section on the line 5`-5 of Fig. 2. Fig. 6 is a detail in section on the line 6-6 of Fig. 2.
'Referring s eciiically tothe drawings, A indicates the ody of the carbureter or mix- This is an upright hollow cylvalve J, which opens upwardly at the inspirationof the engine and is at other times held closed by its weight and by a spring K coiled around its stern. At the top the 'cylinder isconnectedto a pipe 'or fitting V which has a lateralOutlet-X to the engine.
Located centrally within the cylinder is an oil or fluid fuel chamber B, which is held in the center and supported in the bod y by three wings O fitting and fixed within the c linder. The chamber or vessel B receives t 1e fluid fuel through a pipe T which 1s provided, outside the carbureter, with an air chamber S to cushion the stroke ofthe pump. The chamber B is closed at the bottom by a 'removable screw plug b which also has a bore y forming a guide for the stein-of the valve J in connection with the vessel B, a pump is formed by means ofa plunger C and a sleeve D. The plunger and sleeve work through a bushing u in the top of the pipe litting V and also throu h a collar at thetop of the vessel B. The s eeve D fits over the reduced stem of the plunger C, and thehead of the plunger, and the sleeve, are of the samt` diameter, and
they work at a snug fit through the collar or` opening at the top of the vessel B..
` The sleeve D has a limited and adjustable sliding movement upon the stem of the plunger, between the shoulder Y at the head of the plunger and a collar F at the top of the stem thereof. The collar F is loose on the stem of the plunger, but is retained in position by a key f, which Works in a roove in the stem, and by an adjusting nut (r screwed on the end of the stern. T he'nut is held at adjustment by a s ring detent E which is fixed to the collar and engages the knurled rim of the nut. The upper end of the sleeve l) is fixed to the upper cross piece M of a working frame, by means of' jani nuts l. This frame has also a lower cross piece- M', and connecting rods M'l fastened to the cross piece by nuts H. The connecting rods M2 work through holes in ears c projecting from opposite sides 'of the casing A, and the lower cross piece M has ears N for the attachment or connection of the frame to a connecting rod or other reciprocating part of the engine, whereby the pump is operated.
In the fitting V, opposite to the Outlet X to the engine, is an auxiliary air valve consistin of a plug P the outer end of which has ho es p controlled by a turning disk R having holes r which may be registered or not registered with the holes p. The plate R is held in position by a screw R and nuts R2. At the inner end the plug has a check valve Q, opening inwardly.
Located within the vessel B are a pair of opposite spring fingers having friction pieces L which embrace the head of the plunger C- and serve to prevent any movement thereof except when positively operated. Extending across the chamber A, just below the collar of the vessel B, is a gauze diaphragm Z,
to distributeltlic oil or other fluid fuel delivered by the pump so that it may be readily taken up iby the air flowing through the chamber.
In operation, the sleeve D is reciprocated by means of the working frame, and its movement carries with it the plunger C. On
of this space governs the amount of the feed,
and is ca' able of variation by adjustment of theimt On the liftof the sleeve, the oil or other fluid fuelin the vessel B fills the said spa-ce, and continued up lift of the sleeve and?" i, plunger carries' the same above the top of the lso . and the mixture passes through the 'outlet X 35 The auxiliary air valve may j vessel y ried up inisaid space at Y then flows out onto the gauze Z, being positively discharged by the ensuing down stroke of the sleeve'l), which first strikes the shoulder Y and then pushes the plunger down into the vessel B for the nextgoperation. The friction pieces L serve to prevent movement of the plunger C except When positively actuated by the sleeve D. The opeigation of the pump/is so timed that the fluid will be discharged onto the gauze at the suction stroke or inspiration of the enine, which draws'air up through the holes 7V and chamber A .where it vaporizes the oil or other fluid fuel on the diaphragm Z,

This auxiliary vilveis useful at high speeds. y
Itwdill be seen that after adjustment the same amount of oil or other fluid fuel is positively delivered at each stroke of the pump,
