ARTHUR GRAHAM FRANCE, OF HOLIBORN, LONDON, ENGLAND.
CARBURETER-NOZZLE.
To all whom it may concern:
Be it known that I, ARTHUR GRAHAM FRANCE, a subject of the King of Great Britain, residing at 29 Southampton Buildings, Holborn, in the county of London, England, have invented certain new and use ful Carbureter-Nozzles, of which the following is a specification.
This invention relates to nozzles for carbureters for internal combustion engines.
According to the said invention a tubular member is provided having a cap at top to form a chamber between the fuel orifice or orifices in the carbureter jet and the said cap the edge part of which cap overhangs or projects beyond the exterior of the tubular member and apertures are provided in the cap portions of each of which lie on opposite sides of its junction with the said tubular member so as to form passages through the cap for fuel from the interior of the tubular member in close juxtaposition to passages in the projecting portion of the cap for air from the space around the tubular member thereby providing for intimate mixture at or above the cap of the currents of fuel and air respectively passing through the said apertures in the cap, the fuel passing to the en- I gine in practically a completely atomized or vaporized condition.
In order that the said invention may be clearly understood and readily carried into effect I will describe the same more fully with reference to the accompanying drawings in which like letters of reference are used to indicate similar parts in all the figures.
Figure 1 is a side view on a large scale of a device conveniently embodying the invention, Fig. 2 is a plan thereof. and Fig. 3 a vertical section; Figs. 4 and 5 are respectively a vertical section and plan of the cap when provided with the means of adjustment hereinafter described.
a is a metal tubular member carrying the metal cap 6 which is of conical form with an overhanging circumferential edge part or rim 6 and is secured to the upper edge of the member a which is slightly enlarged or expanded at and near that part as shown at a. The cap 5 is provided with holes 0 c at the part where it is secured to the member 5 so that each hole is approximately bisected through its center and approximately half of each hole 0 consequently communicates with the interior of the member a and the Specification of Letters Patent. Patgntgfl Jung 20 19][(;

other half of each hole 0 communicates with the air space or conduit around the member a.
The member a, fits friction tight over the carbureter jet (Z Fig. 1, so as to form a chamber between the top (Z of the said jet and the cap 6 as illustrated in Fig. 1 and a stop may be provided to insure that the member a is placed in such position on the (Z that the said chamber is of the proper predetermined size. In Fig. 1 the ordinary choke tube for supply of air to the engine cylinder is indicated by the broken lines at c.
When the engine is working air is drawn through the choke tube and a portion of the current of air impinges against the overhanging edge part or rim Z) and air is drawn through the outer parts of the holes a 0. At the same time fuel is drawn through the usual orifice or orifices in the top of the carbureter jet whence it passes through the interior of the tubular member a;- constituting the said ehamber and through the inner parts of the holes 0 c. Currents of air and fuel are thus brought into intimate contact above the cap 7) by which means the fuel is very finely atomized or vaporized and thoroughly mixed with the air.
- In cases where it is desired to provide for regulation of the quantity of fuel and air passing through the cap 7) it is providedwith an additional cap of similar shape and having holes similar to those in the said cap 6; the said additional cap is mounted above and secured on the upper face of the cap Z) in such manner that it may be partially rotated thereon and may act as a hit and miss regulator. Such an arrangement is illustrated in Figs. i and 5 in which f is the said additional cap riveted or pivoted at its center to the cap 6 and provided with'a pro- ,jection f whereby it may be turned on the cap 6. On examining the said figures, which show the cap f in such position as-slightly to cover the holes 0 in the cap Z) it will be seen that the cap f is in close contact with the cap a. The friction between the two caps should be suflicient to prevent accidental movement of the cap 7 while not too great to prevent adj ustment by hand. By partially rotating the cap f more or less the passages throughthe. holes 0 may be more or less closed as desired.
If desirable the tube a may be slotted or slit for a part of its length in order to make it slightly resilient and so improve its fricjet.
tional fit on the carbureter jet and the cap 7) is secured to the tube a by soldering or by bending over the ears on the tube a after engaging them in slots in the said cap or in other suitable manner. 7
It is obvious that the tubular member a with its cap may be applied to the carbureter jet at the time of manufacturing the carbureter, or said tubular member with its cap may be sold as an attachment to be later applied to the 'carbureter jet. The tubular member a serves as a connecting means between the carbureter jet and the cap and serves to support the perforated cap over the fuel-delivery orifice of the carbureter So far, as the broad aspects of the invention are concerned, the cap might be attached directly to the carbureter jet without departing from the spirit or scope of the invention, as defined in some of the accompanying claims. In either instance,that is, when the tubular member a is used, or when itis not used, the'cap is-disposed over the fuel-delivery orifice of the carbureter jet within the meaning of this expression as used in the following claims.
