1 Claim.

This invention is a device which may be termed a natural gas dispenser, being adapted especially for projecting natural gas together with a sufiicient quantity of air into an internal combustion engine for use thereby as fuel.

An object of the invention is to provide a device of this character which may be readily applied to an internal combustion engine and controlled from a dash control device or in any other suitable manner for supplying a mixture of natural gas and air into an internal combustion engine.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings, wherein:

Figure 1 is a side elevational view of the device.

Figure 2 is a top plan view thereof.

Figure 3 is a vertical sectional view therethrough and.

Figure 4 is a transverse sectional view taken substantially on the line 4-4 of Figure 1. Referring to the drawings by reference numerals it will be seen that the device is in the nature of a carbureter and includes a cylinder 5 to the upper end of which is secured a collar 6 provided with an apertured flange 1 whereby it may be secured by suitable fastening means to the neck of the intake manifold of an internal combustion engine for securing the device in position on the internal combustion engine. Adjacent the bottom thereof the body or cylinder 5 is provided with a series of air ports 8 controlled by a sleeve valve 9. The sleeve valve 9 has apertured lugs I0 integral therewith and slidably engaging guide rods II that have ends extending through apertures provided in ears I2 integral with the collar 6 and ears I3 integral with the cylinder 5 at the lower end of the cylinder. The upper ends of the rods I I are provided with cotter pins I l while the lower ends of therods are provided with nuts I5. The sleeve valve 9 is normally urged downwardly into a closing position with respect to the ports 8 through the medium of 'coil springs I6 disposed about the rods between the ears Ill and I2.

In the bottom thereof the cylinder 5 is provided with an aperture through which there projects the tubular body I! of a fuel jet which is suitably coupled .at its lower end with an elbow I8 that in turn serves to connect the jet with a conduit or the like leading from a suitable source of supply.

The upper or inner end of the body I! of the jet is tapered and is provided with a substantially frusto-conical discharge orifice I9, and at the inner end of this orifice with a substantial frustoconical valve seat 20.

Arranged to engage the valve seat 20 is a substantially conical valve 2| provided with a stem 22 that is pivoted at its upper end to an arm 23. 5 Arm 23 at one end is pivoted to a suitable bracket 24 mounted within the cylinder 5 adjacent the upper end of the latter. The valve M is normally urged upwardly into engagement with the seat 20 through the medium of a coil spring 25 that 10 impinges against the valve 2| and has a bottom end resting on a suitable annular ledge 26 provided therefor internally of the body I I of the jet.

For controlling the operation of the valve 2! there is provided a control rod 21, and this rod 15 at its upper end is pivoted to the free end of the arm 23 as clearly suggested in Figure 3.

At its lower end the rod 27 extends through the bottom of the cylinder 5 and is provided with a lateral projection operating in an arcuate slot 28 provided in one end of a gas control lever 29.

The gas control lever 29 is pivoted intermediate its ends to a bracket plate 30 that has an apertured flange portion thereof clamped between one of the ears I3 and a nut I5 on the guide rod II extending through said one ear I3.

Any suitable mechanism may be provided for controlling the operation of the device, and as shown such mechanism may consist of a lever divided into two parts and having end portions 30 SI pivoted as at 32 to opposite sides of the sleeve valve 9. Adjacent the ends 3| the parts of the lever are also pivoted as at 33 between upstanding links or posts 34 pivoted at their lower ends as at 35 to a plate 36 clamped between a sec- 35 ond one of the ears I3 and the nut I5 on the rod I I passing through the aperture in the second named ear I3 as suggested in Figure 3. As shown in Figure 2 between one of the pivots 32 and the free end of the lever 29 there is a link 40 connection 31 and for connecting one end of the link 31 with the gas control lever 29 the latter lever is provided with a series of openings 38 and bolt and nut means 39 carried by the link 37 is engaged with a selected one of the apertures 45 38 to adjustably connect the link 31 and lever 29. The aforementioned lever includes besides the end portions 3I shank portions 3Ia connected by bolts 40, and the shank portions cm are of dilferentlengths as clearly shown in Figure 2. 50 The longer of the shanks 3Ia is provided with a flange having an aperture for rotatably receiving the head equipped end of a screw 4| which latter, at the end opposite to the head thereof is swivelly connected with a flange on one end of a plate 42 and is secured through the medium of the bolt 40 between parallel portions of the shanks 3|a. On the bolt 4| there is a nut 44 carrying an apertured lug for engagement with one end of a Bowden wire or the like forming part of a remote control device for the dispenser.

From the above description it will be apparent that in operation when it is desired to admit a quantity of natural gas and air into the internal combustion engine the operator pulls on the remote control device to rotate the lever 3Ia and thereby move the valve 9 to the open position suggested in Figure 3. This upward movement of valve 9 will cause a pull on the link 31 for rotating the lever 29 in a counterclockwise direction resulting in a downward pull on the valve control rod 21. This pull on the rod will cause the arm 23 to move downwardly for unseatlng the valve 2| against the action of spring 25 so that in fully open position the parts are as shown in Figure 3. With the parts in open position natural gas from a source of supply will flow through the elbow IS the jet l1 and the cylinder 5 into the intake manifold of the internal combustion engine. At the same time air from the atmosphere will be admitted through the ports 8 to mingle with the natural gas as it discharges through the orifice l9, thus insuring a proper mixture 01 natural gas and air to obtain proper combustion.

Having thus described my invention, what I claim as new is:

A device of the class described comprising a cylinder having ports in one end portion thereof, a gas supply pipe entering said end of the cylinder and having a nozzle at its inner end extending into the cylinder to a point spaced inwardly from the ports, that portion of the pipe within the cylinder being concentrically arranged with relation to the cylinder, the inner face of the nozzle having a valve seat therein, a valve located in the pipe, a spring for holding the valve against the seat, a stem connected with the valve and passing through the nozzle into the cylinder, an arm pivoted to an internal part of the cylinder and pivoted to the stem, a rod connected with the arm and passing through the ported end of the cylinder, a lever pivoted to said end of the cylinder and connected with the rod, a sleeve valve slidably arranged on the cylinder, spring means for normally holding the valve in a position covering the ports in the cylinder, a lever pivotally supported intermediate its ends, means for connecting one end of the lever to the sleeve valve for moving the valve to open position when the lever is moved in one direction, and a link connecting the first mentioned lever with the second lever whereby movement of the second lever is communicated to the first lever to open both valves simultaneously against the action of the springs.
