INTAKE-MANIFOLD.

Application filed April 10, 1911. Serial No. 620,242.

To all whom it may concern:

Bejit known that I, WILLIAM E. SCRIPPS, a citizen of the United States of America, residing at Detroit, inthe county of Vayne and State of Michigan, have invented certain new and useful Improvements in Intake-Manifolds, of which the following is a specification, reference being had therein to the accompanying drawings,

It is frequently desirable to use kerosene or the like for the fuel of an internal combustion motor that is otherwise generally adapted for use with gasolene or like "olatile hydro-carbons.

This invention relates to a manifold for internal combustion motors which may be substituted for a manifold of conventional type used in connection with the consumption of gasolene or the like whereby the motor to which the manifold is attached may be driven by kerosene or a similar fuel.

The invention consists in the matters hereinafter set forth, and more particularlypointed out in the appended claims.

In the drawings, Figure 1 is a view in side elevation of a motor-having a carbureter and a manifold that embodies features of the invention; Fig. 2 is a view in side elevation of the motor and attached parts; Fig. 3 is a view in detail, partially broken-away. of the manifold on the engine side; Fig.4 is a plan view partially broken away of the manifold; and Fig. 5 is a view in transverse section taken on orabout line 55 of Fig. 3.

As herein indicated, an explosive engine 1 of conventional type is provided with a carbureter 2 that is in communication with the several inlet openings of the motor cylinders 3 through a manifold 1. The usual valve mechanism indicated at 5 of any preferred type controls the intake and exhaust from each cylinder in the usual manner.

As herein shown as a preferred formof construction. the manifold consists of an outer shell 6 having a plurality of fuel outlet openings 7 adapted to be connectedto the corresponding intakes of the cylinders and in communication through a common fuel passage 8 with a fuel inlet opening 9 that is connected as by a fitting 21 or the like with the outletof the carbureter 2. A plurality of exhaust intake openings 10 are in communication with the exhaust outlets of the cylinders and are connected to a common exhaust outlet-11 in the manifold by an exhaust passage 12 that is separated from the fuel passage 8 by an in terior division wall 13, and is arranged to partially envelop or jacket the fuel passage. To further jacket the fuel passage an air duct 14 extends longitudinally through the manifold along an interior division wall 15 which divides it from the passages. An air outlet 16 may be connected, if desired, as by a suitable fitting 17, with the air intake of the carbureter 2 so as to draw air from theend openingslS of the duct through the full length of the manifold and thereby warm the carburetor air suppl As a preferred method of securing the manifold in place bolt tubes 19 extend transversely .through themanifold to receive studs or bolts'indicated at 20, the bores of I Specification of Letters Patent. Patented J uly 18,191 1- the tubes not beingin communication with the passagesor ducts of the manifold.

While herein shown as an integrally formed structure, the manifold may be built up if desired! perature for effective use of kerosene or the like.

Obviously, changes in the details of con;

struction may be made without departing from the spirit of the invention and I do notcare to limit myself to any particular form or arrangementof parts.

hat I claim is 1. A manifold for explosive engines hgving a fuel intake opening in communication with fuel outlets through a fuel passage, an exhaust outlet in communication with exhaust intake openings through an exhaust passage substantially enveloping the fuel passage, and an air outlet opening connected to air intake openings by an air duct separated from the fuel and exhaust passages by a division wall.

2. A manifold for explosive engines hav- 'etlicient means for maintaining deslred teming a fuel intake opening in communication with fuel outlets through a fuel passage, an

exhaust outletin communication with exhaust intake openings through an exhaust passage substantially enveloping the fuel passage. an air outlet opening connected to air intake openings by an air ductseparated from the fuel and exhaust passages by adivision wall, and with boltholes extendingi completely through its body separate from the passages and ducts.

3. A manifold for explosive engines having a fuel intake opening connected to fuel outlet openings by 'afuel passage, an exhaust outlet connected to exhaust intakes by an exhaust passage substantially inclosing the fuel passage from which it is separated by a division wall within the manifold, and an air outlet opening connected with air in take openings by anair duct separated from the fuel and exhaust passages by a division wall.

t. A manifold "for explosive engines having a fuel'intake opening in communication with a plurality of fuel outlets through a fuel passage, an exhaust outlet connected to exhaust intakes by an exhaust passage, and

an air outlet connected to air inlets by an air passage, the fuel passage being substantially enveloped by the exhaust and air passages.

5. The combination with an explosive engine and a carburetor therefor, of a manifold having a fuel intake opening connected to the carbureter discharge, fuel outlets in communication with the cylinders connected by a fuel passage to the manifold fuel intake, exhaust intake openings in communication with the motor cylinder exhaust connected with an exhaust outlet by an exhaust passage substantially enveloping the fuel passage, and an air outlet opening connected to air intake openings by an air duct separated from the fuel and exhaust passages by a division wall.

6. The combination with an explosive en' .tia-lly inclosing the fuel passage oeaiaa gine and acarbureter therefor, of a mani- -,fold havingfuel intake openings connected to the carburetor discharge, fuel outlets in communication with the cylinders connected by a fuel passage to the manifold fuel intake, exhaust intake openings in communication with the motor cylinder exhaust connected with an exhaustoutlet by an exhaust passage substantially enveloping the fuel passage, and an air outlet opening connected to air intake openings by an air duct separated from the fuel and exhaust passages by a division wall, and a fitting adapted to connect the air outlet opening with the air intake opening of the carbureter.

7. The combination with an explosive engine and a carbureter. therefor, of a manifold having a fuel'intakeopening connected to the discharge of the carbureter, fuel outlet openings connected to the fuel intake opening by a fuel passage and to the fuel in- [take openings of the motor cylinders, an exhaust outlet, exhaust intakes connected to the outlet by an exhaust passage substanfrom which it is separated by a division wall within the manifold and adapted to register with the exhaust openings of the motor cylinders, and

an air outlet connected with air intake openings by an air duct separated from the fuel and exhaust passages by a division wall connected to the air intake of the carbureter.

ln testimony whereof I affix my signature in presence of two witnesses.
