GAS-SAVING AND CARBON-ELIMINATENG ATTACHMENT FOR AUTOMOBILE GAS ENGINES.

Application filed September 1, 1920. Serial No. 407,421

To all whom it may concern.

, Be it known that 1, JOHN HENRY ZUR- nons, a citizen of the United States, residing at Covington, in the county of Kentonand State of Kentucky,have invented certain new and useful Improvements in.

Gas Saving and Carbon Eliminating Attachments for Automobile Gas Engines, of which the following is a specification.

My invention relates to novel means for withdrawing the exhausted gases, hot air and unconsumed products of combustion from the engine exhaust manifold directly to the intake manifold by means of a tube or pipe having a stop-cock therein. I

The object of my invention is to provide a simple, convenient and economical attachment adapted to be readily and easily applied to the machine by a mechanically unskilled person and to provide efficient means whereby the mileage for each gallon of gasoline is greatly increased, and whereby carbon is eliminated from the cylinders.

My invention consists in the novel combination and arrangement of parts, and in the simple and convenient means for attaching it in position for use as herein set forth and claimed.

In the drawings:

Fig. 1 is a perspective view of a gas engine with my gas-saving and carbon-eliminating attachment mounted thereon;

Fig. 2 is an elevation partly in section of my attachment and engine cylinder to which it is connected; T

Fig. 3 is a plan view of the engine showing the position of the attachment when connected;

Fig. 4: is an elevation from the rear show- 4.0 ing connection of attachment and position of the priming cup; and

Fig. 5 ma perspective view of the collar located between the engine and exhaust, showing threaded hole into which the attachment is screwed.

In the embodiment of my invention as illustrated and which shows a preferred construction, a collar 1 is inserted between carbureter 2 and the lower end of intake-mani-' fold 3 to both of which it is attached. Said collar is provided with a threaded opening 4 in which the lower end of connecting tube 5 is screwed. Connecting tube 5 extends upwardly and laterally over exhaust-manifold 6 where it connects with branch tubes 7 and 8 leading downwardly into insert connec tions 9. These insert connections are illustrated in Fig. 5 and are provided upon one end with. an annular recess 11 to receive gland 12 inserted in engine casing 13, a gasket 14 being interposed between said insert connections, and the engine casing to form a tight joint. The other end of said insert connections are each provided with an annular flange 15 to enter annular recess 16 in exhaust-manifold 6. Insert connect-ions 1O exactly like insert connections 9, except that they are not provided with threaded openings 9, are inserted between engine casing 18 and exhaust-manifold 6 for the purpose of establishing suitable connections between said casing and manifold when my attachment is applied.

Connecting tube 5 is provided with stopcock 17 by which hot exhaust gas from the exhaust-manifold to the intake manifold is controlled. Said stop-cock is preferably provided with rod 18 arranged in convenient position for the driver and provided with handle 19 by which it is operated to turn on or ofi the supply of exhaust gas from the exhaust-manifold or to control the supply thereof to the intake manifold, as may be desired. A priming cup20 is mounted at the upper end of connectingtube 5 into which a small quantity of gasoline may be poured for the purpose of starting the engine when it is cold, and a suitable stop-cock 21 is provided for closingofi the priming cup when not in use.

When it is desired to equip an engine with my attachment, the parts of which are assembled as shown in Fig. 2, simply disconnect carbure-ter 2 and the lower end of intake-manifold 3 and also disconnect exhaust-manifold 6 from engine casing 13 and insert collar 1 between said carbureter and intake-manifold, as shown in Fig. 1, and insert connections 9 and 10 between exhaustmanifold 6 and engine casing- 13, as clearly shown in Figs. 2 and 3. The engine thus equipped is then ready for use and, since no tapping of the engine or other parts is required, the attachment can be readily, conveniently and quickly applied by any person though mechanically unskilled. Furthermore, my invention provides'an attachment which prevents the possibility, of damaging the engine casing, exhaust-manifold or intake-manifold by one Who is not skilled in attempting to apply it to said parts by tapping therein.

An advantage of this attachment over others is that the heated exhaust gas is conducted directly to the intake inanifold thereby causing better distribution and mixing of the fresh and exhaust gas and unconsumed v products of combustion' Iclaimz 1. In an autoinobile gas enginey'anengins-casing, an exhaust-manifold, a carbureter, an ntake-manifold, a tubular connection having acollar at one end adaptedto be detachably inserte'dbetween and connect;-

"ed to the carbureter and intake manifold an intake manifold, an insert connection an automobile gas engine, an engine comprising a short tube having a threaded side opening therein, said tube' also having upon one end thereof an annular flange and upon its otherend an annulai-recess adapted to form connection With the engine casing andexhaust manifold, respectively, and a tubular connection detachably. mounted at one endbetween said carhureter and said intake manifold and attachable at the other end to saidvinsertnconnection, substantially asset forth and for the purposes specified.

- JOHN HENRY 'ZURBOR-G.
