AIR-STRAINER ATTACHMENT FOR CARBURETERS.

Application filed. January 30, 1917.

To all whom it may concern:

Be it known that I, AUSTIN O. CRAVEN,

a citizen of the United States, residing at Colfax, in the parish'ofGrant and State of Louisiana, have invented new and useful Improvements in Air-Strainer Attachments for Carbureters, of which the following is a specification.

This invention relates to attachments adapted to be applied to carbureters to strain the air which is admitted to the same whereby dust is prevented from entering the carbureter and the engine to which it is attached.

The parts of the device are so arranged that it may be used for introducing gas into the engine for the purpose of starting the same and hence the attachment may be used as an engine starter in addition to the functions which it performs as an air strainer.

With these objects in view the attachment comprises a cylindrical body having at one end a nipple adapted to be inserted in the air intake end of the carbureter casing. A screen is located 'in the said body and a cap is detachably mounted at one end and is provided at its central portion with a screen. A filtering material as for instance cotton fiber is located in the body between the screens and a funnel is mounted upon the top side of the body and the said body is provided at the lower end of the funnel with openings through which gasolene may be passed into the body and the filtering material.

In the accompanying drawing Figure 1 is a perspective view of the car bureter showing the attachment applied;

F i 2 is a vertical sectional view of the attac ment; M r

Fig. 3 is a transverse sectional view of the same;

Fig. 4 is a fragmentary side elevation of a part of the same.

As illustrated in the accompanying drawing, the carbureter 1 may be of any usual pattern and is provided with an air intake sleeve 2. The attachment comprises a cylindrical body 3 of sheet metal having at one end a tubular nipple 4 adapted to be inserted in the sleeve 2 and adapted to frictionally engage the same. A screen 5 is located in the body 3 at a point between the ends thereof and is disposed transversely across the said body. A cap 6 is adapted to slip on'that end of the body 3 opposite Specification of Letters Patent.

the end at which the nipple 4 is located and the said cap is open at its center and the said opening is provided with a screen 7. Filtering material 8 as for instance cotton fiber is located in the body 3 between the screens 5 and 7. A funnel 9 is mounted upon the top side of the body 3 and openings 10 are provided in the top portion of the said body 3 and communicate at their upper ends with the lower end of the funnel 9. The said openings 10 are located at the opposite sides of a vertical plane which passesthrough the centers of the body 3.

When the attachment is applied to the carbureter and as the air is drawn into the carbureter it passes first through the screen 7 and then through the filtering material 8 and then through the screen 5 andthe nipple 4 into the carbureter. As the air passes through the said material 8 it is relieved of dust or foreign matter and hence the attachment prevents the dust from entering the carbureter and the engine to which it is attached and prevents the damage which is due to the admission of dust to these parts.

When it is desired to start the engine gasolene or oil may be poured into the funnel 9 and the said liquid will pass through the openings 10 into the filtering material 8 and consequently as the air is drawn through the said filtering material it is carbureted and may be used to advantage for starting the engine. By reason of the fact that the openings 10 are located at the opposite sides of the plane which passes vertically through the center of the body 3 the liquid which is poured into the funnel 9 is distributed at the opposite sides of the said plane in the filtering material 8 and consequently as the air passes through the said filtering material it is efi'ectually saturated and enters the carbureter in the form of a mixture or gas and from the carbureter passes into the engine where it is exploded in the usual manner when the engine is started.

From the foregoing description taken in conjunction with the accompanying drawing it will be seen that an attachment for a carbureter of simple and durable form is provided and that the same may be used to advantage for removing particles of dust and other foreign matter from the air which enters the carbureter and may also be used to advantage for carbureting the air which is admitted into the carbureter and the engine cylinder at thetime. that the operation of the engine is begun.

Having described the invention what is claimed is 1. A-carbureter attachment comprising a body having at one end a nipple adapted to be inserted in the air intake of the carbureter, a screen located in the body at a point between the ends thereof, a cap detachably mounted upon the body and provided at its center with an opening, a screen located over thevopening of the cap, filtering material located in the body between the said screens, a funnel mounted upon the body, the said body having openings which communicate with the interior of the said funnel.

2. A carbureter attachment comprising a body having nipples adapted to be inserted in the air intake of the carbureter, a screen located in the body at a point between the ends thereof, a cap detachably mounted upon the body and provided with an opening located at its center, a screen located over the opening of the cap, filtering material located in the body between the said screens, a funnel mounted upon the body, said body being provided with openings which communicate at their upper ends with the interior of the funnel, the said openings being located at the opposite sides of a vertical plane which passes through the center of the body.

In testimony whereof I afiix my signature.
