UNITED sTATEs PATENT .oEEioE GLENN A. HEDRIGK, or SEATTLE, WASHINGTON,
FUEL-MIXING DEVICE.
T0 all whom t may Concern Be it known that I, GLENN A. HEDRICK, a citizenfof the UnitedStates, residing at Seattle, in the county of King and State of V'ashington, have invented certain new and useful y'Improvements in Fuel-Mixingv Devices for Internal-Combustion Engines; and I do declare the following to be a full, clear, and exact ,description .of the invention, such aswill venable others skilled in the art to which it appertains to make and use the same.
This invention relates to certain new and useful improvements in fuel mixing devices designed more particularly for use in connection with' internal combustion engines.
The primari7 object of the invention is to provide a device to be placed `either in the intake `manifold at onek or the other of its extremities, or in the carbureter of an internal combustion engine, said device being adapted to thoroughly mix the fuel and air in its passage from or through the carbureter to the cylinders of the engine, and being designed to break up the liquid fuel and the air by causing these elements to come into closer contact after having left the mixing chamber of the carbureter.
Another object of the invention is to improve upon the devices of this character by the provision of a simple, comparatively strong, durable and inexpensive device, and one which is efficient and reliable in operation and well adapted to the purpose for which it is designed.
With these and numerous other objects in view, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.
In the accompanying drawings, forming a part of the specification, and in which similar reference characters designate like parts throughout the several views:
Figure 1 is a side elevation of an internal combustion engine, showing a device con- V structed in kaccordance with this invention arranged in the intake manifold thereof adjacent the carbureter, a portion of said intake manifold and said carbureter being shown in section;
Fig. 2 is a side elevation on an enlarged scale of the mixing device detached from the engine;
Fig. 3 is a top plan view of the same;
Fig. 4 is a horizontal sectional view taken Specification of Letters Patent.
on the plane of the line 4-4 of Fig. 1, showing more particularly the Imanner in which the device is clamped between the flanges of the intake manifold and carbureter of the engine;
Fig. 5 is a vertical sectional view through an ordinary form of carburetor showing ay mixing device installed therein; and,
Fig. 6 is a top plan view of a portion of a mixing. device, showingthe'modified form of a baflie device mounted 'on the smaller.
E Patented Auf. 2i, 1917. t Application flied May 25, 1916. serial No. 99,812.
The reference numeral 1 designates a resilient member in the formA of a conical spiral spring, the latter being preferably constructed from a comparatively thin fiat strip .ofvery resilient material 'and having its larger end clamped between the flanges a and b of the intake manifold and carbureter respectively, as clearly shown' in Figs. 1 and t of the drawings. Any other suitable and equivalent means for attaching the larger end of the spring 1 to the intake manifold or carbureter of the engine may be employed instead of the means herein shown. The apex of the spring l, or in other words, the smaller end thereof, is provided with a pivot stud 2 on which is rotatably mounted an agitator 3, the latter being preferably formed from a metal plate and having a plurality of blades 4L arranged on its periphery. Although the number of blades is immaterial, four are here shown.
In Fig. 5 of the drawings the mixing device is shown mounted or installed in any convenient manner within thevmixing chamber of the carbureter. It is to be here noted that the device may be arranged at any convenient position within the intake manifold or carbureter of the internal combustion engine so long as it is in a fuel feeding member thereof, that is, so long as it is disposed in a member adapted to convey the fuel from the. fuel tank to the cylinders.
In Fig. 6 of the drawings the agitator 3 is substituted by a flat disk or bottom 5, which similar to the agitator 3, is in effect a baffle device for a purpose to be hereinafter g e i g, 1,237,779
