Patented May 10, 1938 UNITED STATES l PATENT OFFICE CHARGE ronmnc DEVICE Foa INTERNAL cosmos-non ENGINES Raoul E. Chartier and. Romeo A. Char-tier, Holyoke, -Mass.
Our invention relates to a charge forming device for internal combustion motors and it consists in the constructions, arrangements and combinations herein described and claimed.
It is an object of the invention to provide a mixing device, in the form of a blower for thoroughly mixing the gaseous charge received from the carburetor prior to its entrance to the intake manifold of an engine, thereby supplying the engine with a highly ignitable charge, and one which is substantially free of carbon deposits.
It is a further object of the invention to provide a mixing device which will so thoroughly mix a fuel charge that only a vapor is supplied to the engine, thereby eliminating dilution of the oil in the crank case of the engine, as well as preventing carbonization of the oil and further eliminating development of carbon monoxide gas.
It is a still further object of the invention to provide a device which may be installed upon cars now in use, by ordinary mechanics.
Additional objects, advantages and features of invention will be apparent from. the following description, considered in conjunction with the accompanying drawing, wherein Figure 1 is a side elevation of our device, associated with an intake manifold and carburetor of an engine.
Figure 2 is a vertical sectional view through the device.
Figure 3 is a sectional view on the line 3-3 of Figure l. l
Figure 4 is a cross section on the line ll of Figure 1.
Referring now to Figure 1, there is illustrated an intake manifold ID of an "engine to which there is attached a fuel mixture line H as is customary, the opposite end of the line I! being connected with the outlet port 12 of our mixing device, generally indicated at 13.
The mixing device it comprises a cylindrical housing M having a suitable footing 15 for mounting upon a cross brace it of the engine frame. Upon one side of the housing there is formed a tubular extension I! forming communication between the housing H and a carburetor i8 by way of a port IS. The port I!) may have a flange for attachment of the carburetor or otherwise, as found most practical. The extremity of the extension IT is formed with a threaded bore H for reception of a pipe and packing gland 2i. The gland secures the pipe within the bore, and the opposite end of the pipe is passed through a suitable aperture formed in the fuel mixture line H terminating immediately above the outlet port I! of the blower or mixing device IS the open end of the pipe'being presented toward the blower.
The mixing device includes a removable plate 22 adapted to be bolted to the housing I, this plate including a boss 23 housing a pair of roller or ball bearing races 24, and for the purpose of supplying lubrication to the bearings, a fitting 25 is provided. 10
Revolubly mounted in the housing I there is an impeller 26 which in the present instance comprises a series of radially extended blades of a length stopping short of the inner wall of the housing, the impeller rotating in a plane at right 15 angles. to the extension H. The impeller includes a shaft 21 projected through the bearings 24 to a point exteriorly of the boss for. mounting of a pulley 28.
The mixing device will be so mounted that the pulley 28 will align with the fan pulley of the engine and may be driven by any suitable belt (not shown).
Preferably we install a fine wire mesh screen 29 between the port l9 and the connection with 25 the carburetor, this screen serving to break up the full charge received from the.carburetor.
A drain plug 30 may be installed at a suitable low point of the housing H for the purpose of drawing oiT excess water which may be inherent in the fuel charge but normally there will be only suflicient moisture to impart a necessary humidity to the charge. The drain plug will also permit flushing of the unit to remove any sediment.
The operation The operation will be readily understood from the following description.
Upon starting of the motor a gaseous charge will be drawn into the manifold by suction as is customary and at such time the impeller 26 will be rotated, drawing the mixture through the screen 29 into the extension and finally into contact with the blades of the impeller where the charge is thoroughly broken u by the blades, the vapors of the charge passing through the tube H to the intake manifold l0 and finally to the cylinders of the engine. Certain of the gases issuing from the port l2 will pass through the tube 20 due to suction created by the impeller for further agitation, insuring only the passage of a vapor gas to the cylinders of the engine.
While we have shown and described a preferred form, this is by way of illustration only, and we consider as our own all such modifications in structure as fairly fall within the scope of the appended claims.
1. A charge forming device for internal combustion motors comprising an intake manifold, a fuel mixture pipe having one end connected thereto, a housing connected to the other end of the fuel mixture pipe, a shaft revolubly journalled in the housing, an impeller fixed to the shaft for rotation therewith, said housing having an extension at right angles to the direction ofrotation of the impeller, said extension having a port for establishing communication with theoutlet of a carburetor, drive means for the shaft and impeller for drawing'a gaseous charge from the carburetor into the housing for agitation by the impeller and forceful discharge into the feed line, and conduit means between the extension and the fuel mixture pipe for recircuiating a portion of the gaseous charge.
2. A charge forming device comprising in combination with an intake manifold of an engine, a fuel mixture pipe connected therewith, a blower connected with the other end of the fuel mixture pipe, a carburetor connected with the blower and feeding the gaseous charge thereinto, means for rotating the blower for agitating the charge, and a conduit disposed within the fuel mixture pipe, one end of said conduit having connection with the suction side of the blower, and the other end of said conduit opening upstreamwardly upon the discharge side of the blower, whereby to re-circulate a portion of the gaseous charge.
