To all whom it may concern;

Be it known that I, ARTHUR a citizen of the United States, residing at Sioux Falls, in the county of 'Minn'ehaha and Stateof South Dakota, have invented certain new and useful Improvements in f mounting upon the nipple'22, its opposite end being closed to provide a-head piece '13 Attachments for Internal-Combustion Engines, of which the-following is a specification. l

This invention relates to an attachment for internal combustion engines, and has forits principal object to provide a device-for conducting heated airfrom the exhaust manifold to the intake manifold for the purpose of economizing liquid fuel and for in-.

be used effectively during hot orv cold weather.

Other objects relate to the provision. of

such a construction that theparts required will be few, may be conveniently manufactured, and will. be adapted to sustain the degree of heat to which it may be subjected. 1

vibration and stresses incident toits use and will not be injured by, exposure to the high The invention includes the employment .of

parts having such form and arrangement that adjustments thereof may be conveniently andreadi'lymade for a complete control of the movements of heated air, and a I control of suction in conjunction with the operation of the" carbureter; and also includes novel and useful means for housing and utilizing the heat from the egihaust manifold.

With the foregoing objects in view and others to be mentioned, the invention pre sents a novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing, wherein,-

1 Figure 1 is a view, partly broken" and in section,fishowing the deviceapplied to. the exhaust manifold and intake manifold. Fig. 2 is a v'iew'in side elevation of a barrel member or tubular housing for the valve and valve casing. Fig. 3 shows the ball valve. Fig. 4 is a side view of the valve cas ng. Fig. 5 is an endv1ew of the valve casing.

.Fig. '6'is a'transverse section on line 6 6 of Fig. 4, Fig. 7 is a view showing the inner side of the heht r'eceiving receptacle for the exhaust manifold. .Fig. 8 is a side view of parts, showing the device when mounted,

Referring now to the drawing, I provide a housing member 11, consistingof a tube 12 interiorly threaded at its open end for a lar 15, said collar providing an intake port for and preferably bei'ng disposed substantially at right anglesto the axis of said tubular housing.

and is provided on its outer side, near its open end, with an annular groove 16, within said groom being-disposed'a packing ring at of asbestos or similar material which will not be injured by action of heat, the outer, imperfo'rate end of said valve casing being provided with a threadedstem 17 which is [adapted to traverse the head 13-, centrally,

audio havea threaded connection therewith.

The wall of the valve casing is provided with apertures 18 having an inclination outwardly toward the iinpcrforate endof said valve casing, so that the heated air, while moving, will not be unduly obstructed, but will be thoroughly mixed before entering the intake manifold A ball valve is indicated at 19. It 'is adapted to have a seating in the concaved of the coiled spring 21, saidspring being disposed in the tubular housing with it's respective ends abutting upon said valve and the nipple 22,- said nipple having a threaded connection with one of the walls of the intake manifold 23, comparatively remote from the carbureter (not shown) and, preferably, bear the branches (1 of said intake manifold, said nipple being provided at its discharging end'with a projecting part or ledge Z nearest to the incoming gas from the carburetor, and operating as a deflector or shield, so that the'heated air, from the tubular housing may move freely within theinta-ke manifold, and that its movement,

will not be unduly impeded.
