To all whom it may abmm:

Be it known that I, MoNnoE WV. CARROLL, a citizen of the United States, residing at Beaumont, in the county of Jefferson and State of Texas, have-invented certain-new and useful Improvementsin an Attachment for Internal-Combustion Motors, of which the following is a specification.

This invention relates to new and useful improvements in an attachment for internal combustion motors.

One object of the invention is to provide an attachment of the character described whereby the fuel line and carbureter may be readily cleansed of clogging material, and the quantity of motive fluid in the fuel tank also readily ascertained.

With the above and other objects in view, this invention has particular relation to certain novel features of construction, use and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a fragmentary vertical sectional view of a motor vehicle, showing the attachment applied thereto.

Figure 2 shows a vertical sectioal view of the gauge tube.

Figure 3 shows a fragmentary front elevation thereof; and

Figure 4 shows a fragmentary plan view of the carbureter connections.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates the motor, the numeral 2 the carbureter, and the nu meral 3 the fuel tank of the vehicle 4. A fuel feed line leads from the fuel tank 3 and is connected into the valve casing 6. This casing has a duct 7 therethrough into one end of which the line 5 is connected, and leading from the other end of this duct 7 there is a tube 8 which is connected into the lower end of the upstanding gauge tube 9. This tube is of metal and the tube is located just behind the vehicle dash board in view of the driver. The rear portion of the upper part of this tube is cut away, and enclosed within the upper part of this tube 9 there is a transparent tubular section 10. Within the tube 9 there is a float 11 and upstanding from it is a gauge rod 12. A nipple 13 is threaded onto the upper end of the tube 9, and is extended through the cowl of the vehicle and secured in place by the lock nut n ipple jl fiwhich is'threaded.into-thefuel in- 1 1; This nipple is tubular and its free endlis threaded so .as to provide for the. connection of a pneumatic'pump'thereto- The; valvecasing 6 has .a lateraltubular take'oftlie carbureter and has an axial-duct 16, connecting withthe duct 7. These ducts are controlled by means of.;a three way ro tary valve 17. As shown in Figure 4 this valve is turned to admit fuel into the carbuvalve may be given a quarter turn to the right to close the supply line 5. A pneumatic pump may then be connected to the.

nipple l3 and air forced through the tubes 9 and 8, and through the nipple 15, and the clogging material forced by fluid pressure from the carbureter. If the valve now be given another quarter turn to the right the inlet to the carbureter will be closed and the fuel supply line 5 opened and connected with the tube 8 and by operating said pump the pressure fluid ma be driven through the line 5 to force the o ending clogging material therefrom.

What I claim is 1. A device of the-character described including a'tubular conduitcormected at one end into a fuel tank of an internal combustion motor, and whose other end is upturned forming a gauge tube, and formed with a transparent section, an intermediate connection between said conduit and the fuel intake of the motor carbureter, a valve controlling said conduit, and a buoyant gauge rod in said upturned end, and a tubular nipple forming a pump connection intosaid gauge tube, said nipple also forming anchoring means for said gauge tube.

2. A device of the character described including a tubular line connected, at one end, into a fuel tank and whose other end is upturned forming a gauge tube, and formed with a transparent section, a buoyant gauge formed to connect said line and gauge tube and simultaneously close the carbureter connection, when the valve is in one position and to connect said tube with said connection and simultaneously said line when the valve is in another position and a tubular nipple carried by said gauge tube.

3. In combination, a motor, a fuel tank, a carbureter, a tubular conduit. leading from said'tank, and connected into saidcarburetor and having an upturned end forming, a,

connect 4. In combination, a motor, a fuel tank, a carbureter, a tubular conduit leading from said tank, and connected into said carbureter and having an upturned end forming a. gauge tube, a gauge mechanism in said gauge tube, a valve controlling the conduit and the connection thereof with the carbureter, and adapted to connect the gauge tube, either into the carbureter or into said conduit, or both, when in difierent positions and a pumpconnection carried. by the upper end of said gauge tube, said pump connection also forming means for connecting said MONROE W.
