GAS ATTACHMENT Application filed July '23,
This invention has reference to a device for attachment to an internal combustion engine for adapting the same for the use of natural or artificial gas as a fuel.
An object of the invention is to provide a device of the character above specified which will permit the motor to pick up speed instantly without checking or back firing, and.
which can be used on any single or multiple cylinder, gasoline engine.
WVith the above and other objects in view, the invention consists in the provision of novel and improved carburation means which is adjustable to regulate the feed of the gas and which will enable the engine to operate efficiently at all speeds and under all loads.
The invention consists also in the novel construction, combination and arrangement of parts hereinafter more fully described and illustrated in the accompanying drawings, whereinz' Figure 1 is a side view of an internal combustion engine with the attachment applied thereto,
Figure 2 is a longitudinal sectional view of the invention,
Figure 3 is a vlew similar to Figure 1 showing the attachment as applied to the carbureter of the internal combustion engine.
In its broadest aspect, the attachment per se, as shown in Figure 2 comprises an elongated cylindrical casing 1 having a tapering inlet portion 2 and an air inlet pipe 3 depending from the underside of the casing adjacent the end 2. A gas intake pipe 8 is externally threaded at its outer end as shown at 9 for engagement with a pipe coupling 1O whereby it is connected with a fuel supply pipe 11 leading from any source of natural or artificial gas. The pipe at its other end is disposed within the carbureter casing 1 and provided with a nozzle 12 having an elongated longitudinally extending conical 1930. Serial No. 470,185.
bore 13, the larger end of which is at the outer end of the nozzle.
Disposed within the bore 13 for controlling the passage of gas therethrough is a conical metering plug or valve 14 of a length to extend forwardly and rearwardly beyond the bore 13 and the front end of the valve is provided with a stem 15 pivotally connected by a pivot pin 16 to the lower end of a metering lever 17. The lever 17 operates in a slot in the upper wall of the casing 1 and is pivotally supported on a pivot pin 18 which extends through the disk like hub 19 of the lever. A suitable bracket 20 is mounted on the casing for supporting the lever in position. Lever 17 is connected by a control rod 21 which we tends to the usual gasoline carbureter control lever whereby the lever may be rocked on its pivot to vary the nozzle for regulating the flow of gas therethrough.
The lever 17 is also provided with a longitudinal series of relatively spaced openings 22, in any one of which the end of rod 21 may be inserted. p
In the use of the attachment, the same may be connected either directly to the intake manifold of the internal combustion engine to be used in substitution for the usual gasoline meter as shown in Figure 1, or if desired, the attachment may be attached directly to the carbureter C of the internal combastion engine as shown in Figure 3.
As shown in Figure 3 the casing 1 at the outlet end thereof is provided with a flange 5 for attachment to the flange 6 of the air intake pipe of the manifold. In the operation of the device when usec I in connection with the carbureter C as shown in Figure 3, the natural or artificial gas is drawn into pipe 8 upon the suction stroke of the engine and sprayed into the carbureter 1 through the nozzle opening 13 where it is mixed with air drawn into the air intake 3, and the mixed air and gas is then drawn into the carbureter C to pass therefrom into the intake manifold 7 of the engine.
As shown in Figure 1, and as before inti-- mated, the attachment may be attached directly to the intake manifold 7 of the internal combustion engine. In this connection, it will be seen that the discharge end of the casing 1 is provided with an angle extension 4 which is flanged as at 5' for attachment to the flange 6 of the intake manifold 7 of the engine. In operation, when used in this manner, it will be apparent that the operation is substantially the same as that set forth with regard to the use of the device shown in Figure 3 with the exception that the mixture of air and gas from the casing 1 passes directly into intake adjacent its opposite end, a gas intake unit having its outer end adapted for connection to a source of natural or artificial gas and having its opposite end extending within said casing and terminating in a relatively thickened portion having a conical bore, a conical shaped plug within said bore, an operating lever pivotally mounted on said casing and having one end pivotally connected with the plug, and a control rod adjustably connected at one end with the opposite end of said lever.
In testimony whereof I afiix my signature.

the intake manifold 7 of the engine through g the extension 4.
This attachment is especially adapted for use with the carbureter of the internal combustion engine to' facilitate the easy starting of the engine on gasoline, on particularly cold weather and then switching to'natural gas as a fuel. However, as is apparent, and herein suggested, the attachment may be used with or Without the usual gasoline carbureter. Furthermore, the attachment may be used on any type of internal combustion engine, whether-the motor speed is governed by a hand or foot throttle, or by governor, and enables either naturalvor artificial gas to be used as a fuel.
Even though I have herein shown and described the preferred embodiment of my invention, it is to be understood that the same is susceptible to changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
Having thus described by invention, what I wish to claim as new is:
1. An attachment for internal combustion engines for adapting the latter to the use of natural or artificial gas as fuel, comprising a cylindrical casing provided at one end for attachment to the engine for communication with the interior of the engine and having an air intake at its opposite end, a gas intake unit having its outer end adapted-for connection to a source of natural or artificial gas and having its opposite end extending within said casing and terminating in a relatively thickened portion having a conical bore, the wider end of whichis disposed adjacent the end last referred to of the unit, a conical shaped plug within said bore, an operating lever pivotally mount-ed on said casing and having one end pivotally connected with said plug, anda control rod connected with the opposite end .of said lever.
2. An attachment for internal combustion engines for adapting the latter to the use of natural or artificial gas as fuel, comprising a casing flanged at one end for attachment to the air intake pipe of the carbureter of an internal combustion engine and having an air
