mof a simple-and eflicient means 'for heating I the intake for an explosive engine n such a manner as to cause an efiicient combustion within the explosive cylinder.

Another object of this invention isthe production of a simple and eflicient intake j invention consists of certain novel construcmanifold casting wherein the exhaust. ases from the engine may be passed aroun the ,intake pipe in such a manner as to heat the intake gas to a suflicient temperature to cause an efficient-explosion within the cylinder of the engine.

With these and other objects in view, this i tions, combinations and arrangements of parts, as will be hereinafter fully described and' cla'imed.

' In the accompanying drawings :--Figure 1 is a side elevationof a series of cylinders showing the intake manifold casting applied thereto. Fig. 2 is a view ofthe intake manifold casting from the opposite sideto, that as illustrated in .Fig. 1. Fig. 3 is at end view of the intake'inanifold casting. Fig. 4 is a central sectional view of the in take manifold casting taken on line 4- 1: of

' By referring to the drawings, it will be seen that 1 designates the engine which is F to provided with the usual exhaust manifold casting 2 and the usual ,carbureter. 3 is connected to the cylinders of the engine by means of the intake manifold casting l. This intake manifold casting t-comprises a lower 13eCk'P01t101'1. 5 -\7Yh Ch connects directly to the carburetor? and the casing is also provided with a pair of outlet openings or passageways 6 which connect directly with thecylinders of the engine. The casting 1 comprises a centrally located intake passageway 7 formed therein, and this passageway 7 is so formed as to extend 'centrally of the com Specification of Letters Patent.

partment 8formed by the outer casing 9 of the casting 4. The intake or supply pipe 7 isformed within the casting 4 so as to constitute a substantially T-shaped structure having laterally extending ends 10, as illustrated in dotted lines in Fig. 1 communi eating with the discharge passageways 6 which supply the combustion or heated gases to the cylinders. It will be seen by carefully considering Figs. 1 and 4 that a pocket supply pipe 12 is directly connected to one ofthe compartments or pockets 11 by means of'an angle pipe 13. This exhaust supply pipe 12 is connected to the exhaust manifold 2 by means bf a coupling 14 and a valve 15 11 is formed upon eachside. of-the intake passageway or supply pipe 7 and an exhaust is carried'by the pipe 12 so as to control 'the supply of exhaust from the exhaust manifold casing 2 to the intake manifold casing 4. An exhaust discharge pipe 16 is connected to the opposite pocket 11 by means of the angle connection 17 as clearly .illustrated in Figs. 1 and 4:, and this exhaust discharge pipe 16 allows the exhaust, 'after hav ingpassed through the intake manifold casing, tobe discharged therefrom.

From the foregoing description, it will be seen that a very simple'and efiici'ent device has been produced whereby the exhaustfrom anengine of the explosive character maybe ut-ilizedfor the purpose of heating the intake gases as the samepass through the intake manifold casting. It will also be seen that in view of the fact that the intake manifold casing 1 is provided with an inte-.

grally formed pipe within the body so as to produce pockets upon each side and also I a passageway for the heated gases to pass around the intake pipe, a' very eilieient means has been produced for heating the intake gases in view of the fact that the maximum amount of heating surface. is placed within the intake manifold casting 4. The valve 15 is operated by means 'of the handlelS soas to cut oif the supply of exhaust from the exhaust manifold'casing 2..

From the foregoing description, it will be seen that owing to the construction of, the

,present device the operator will be enabled to use a lower gravity fuel than is ordinarily used by reason of the more efiicient combus tionexplosion which is obtained thereby.

Having thus described the invention, what 'isclaimed as new, is

'1. In. a device of the class describedthe combination with an explosive engine,,an

exhaust manifold casting and an intake --m anifold casing, said intake manifold castingi provided with a substantially V-shaped b0 y having a reduced neck at its inlet end, said intake manifold; casting also'provided -with an integrally formed, centrally arranged intake'supply pipe having a flaring outlet end that terminatesin laterally extending ends, said casting provided with discharge openings for connecting with an explosive engine whereby fuel may be supplied to said explosive engine, said intake manifold casting provided with a compartment extending around said intake supply= pipev formed-within said casting, and means con-.

provided with a reduced inlet end, said intake manifold casting provided with an integral comparatively narrow supply pipe formed therein that' flares outwardly from its inlet and terminates in laterally extending ends,

said intake manifold casting provided with discharge openings in said laterally extending ends, said casting provided with a'com- I partment that surrounds said supply pipe,

-a pipe connecting said exhaust manifold casting with'said compartment for supplying heated gases from said exhaust manito d casting 1nto said intake manifold cast 7 ing, valve means for controlling the passage of heated gases through said pipe, and an exhaust pipe connected to said compartment for discharging heated gases therefrom.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
