ATTACHMENT FOR CARBURETERS.

Application filed. June 15, 1911.

T all whom it may concern:

Be it known that I, HERVEY E. ROGERS, a citizen of the United States, residing at New 7 London, in the county of New London, State of Connecticut, have invented certain new and useful Improvements in Attachments for Carbureters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful attachments for carbureters and the object of my invention is to provide means adapted to co-act with a carbureter to prevent the formation of a carbon deposit upon the inner walls of the cylinder.

A further object of my invention is to provide means which will tend to prevent carbon from becoming deposited upon the inner walls, valve and valve seat of the cylinder.

A further object of my invention is to provide means for accomplishing the above purpose by supplying oxygen to the carbureter.

A still further object of my invention is to provide means for thoroughly mixing this oxygen with air and supplying the mixture so formed to the carburetor.

With these and other objects in view, my invention will be more fully described, illustrated in the drawings which show a preferred embodiment of my device as applied to a conventional form of carbureter and then specifically pointed out in the claim which is attached to and forms a part of this application.

In the accompanying drawings, Figure 1 is a side elevation of the device, showing the same as attached to a conventional form of carburetor, the latter being shown in dotted lines. Fig. 2 is a longitudinal sectional view of the tube, the gas mixing means being shown in elevation. Fig. 3 is a central longitudinal section of the device. Fig. 4 is a transverse section on the line l4l of Fig. 3. Fig. 5 is a similar section on the line 5-5 of Fig. 3. Fig. 6 is a detail perspective of the clamp by means of which the device is attached to the carburetor.

Referring more specifically to the drawings, in which similar reference numerals designate corresponding parts throughout, 1 designates a conventional form of carbu- Specification of Letters Patent.

which is adjustably secured my improved device, which as a whole, is designated by the numeral 3. i

This device consists primarily of a cylindrical tube 1 preferably formed of metal and closed at one end by means of a screw cap 5. this tube being provided adjacent its closed end with an outlet port 6 and adjacent its opposite end with a pair of diametrically disposed inlet ports 7 The open end of this tube is internally threaded to adapt it to receive the threaded end S of a plug 9 which as best shown in Fig. 3 of the drawings is slightly reduced in size to form a shoulder 10 upon which the lower peripheral edge of the tube or casing 4t rests. This reduced portion of the plug is provided with an internally threaded socket 11 in which is secured the threaded stem 12 of a nipple 18 provided with a longitudinally extending capillary bore 14. In order to render a gas tight joint between the nipple and its socket a perforated washer l5 preferably of soft metal is seated in the base of the recess or socket to form a close seat for the nipple. As will be readily understood the supply of oxygen to my device is governed by the size of the perforation in this washer 15. The plug 9 is provided with a centrally located capillary bore 16 which forms a continuation of the bore of the nipple when the latter is in place. The opposite end of the plug is provided with a cylindrical recess 17 adapted to receive one end of a tube 18 which is preferably formed of flexible gas tight material such as rubber. Secured in the end of this tube 18 which enters this plug is a disk 19 preferably formed of metal and provided with a centrally located aperture 20 which communicates with the bore of the plug, the function of this disk being to maintain the mouth of the tube in distended posit-ion and in firm engagement with the walls of the recess.

Extending through and secured to the screw cap 5 by any preferred means as by the nuts 21 is a rod 22 which as shown extends downwardly centrally of the tube 1 and terminates at a point slightly above the inlet ports of the tube. Secured by any preferred means as by soldering to the rod between these inner ports and the outlet port are a plurality of spaced apart, alternately disposed disks of wire gauze and perforated metal, the former being designated by the numeral 23 and the latter by the nur the explosion takes place.

meral 24. These disks are so proportioned as to fit snugly within the tube 4: while at the same time they may be removed therefrom byunscrewing the cap as will be readily understood.

In operation this device is adapted to be positioned with its outlet port adjacent the inlet port of the carbureter and as a means for so positioning the same I have provided a special form of clamping device which as a whole is designated by the. numeral 25. This device consists of a split ring of resilient metal 26 adapted to be sprung about the tube 4 and a second split ring 27 also formed of resilient metal and having its ends bent inwardly as at 28 to form a spring clip adapted to engage with the edge of the inlet port of the carbureter, these rings being swivelly connected by a rivet or other preferred means 29. By this means the device may be supported upon any portion of the port of the carburetor and inclined at any angle while at the same time the tube may be revolved in its clamping ring to bring its outlet port either directly facing the inlet port of the carburetor or directly opposed thereto or at any point intermediate these two.

The operation of the device is extremely simple and needs but little description. With the customary form of carburetor the cylinder is fed with the explosive gas and air which are then mixed and supplied in the proper proportions to the cylinder where Under these circumstances the oxygen contained in the air is insufficient to completely consume the carbon of the gas with the result that the unconsumed carbon is deposited upon the Walls of the cylinder thus decreasing its effectiveness.

With my improved device I supply oxygen under pressure to the tube 18 from which it passes through the nipple and up through the tube 4 drawing in air through the inlet ports of the latter on its way and being thoroughly mixed with this air by its passage through the disks and the tube 4. This mixture of air and oxygen then escapes through the outlet port of the tube and is drawn in through the inlet port of the carbureter. By this means sufficient oxygen may be added to the air to cause complete combustion of the carbon of the explosive gas thus preventing its deposit in the cyl inder.

What I claim is An attachment for carburetors, comprising a tube closed at one end and having an outlet port adj acentsaid end and oppositely disposed inlet ports adjacent its other end, means for supplying oxygen to the tube at a point between its inlet ports, a plurality of spaced apart baffle disks positioned in said tube between its inlet and outlet ports, and means for adjustably securing said tube to the carbureter with its outlet port adjacent the inlet port of the carbureter.

In testimony whereof, I aflix my signature.
