FUEL-CHARGE-TREATIN'G DEVICE.

Original application filed October 12, 1922, Serial No. 594,216. Divided and this application filed November 16, 1922. Serial No. 601,283.

To all whom it may concern:

Be it known that I, VIOLA Roo'r CAMnRoJ, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Fuel-Charge-Treating Devices, of which the following is a specification. I

This invention relates to gas saving devices for internal combustion engines, and pertains particularly to devices for breaking up and mixing combustible charges of fuel and air.

This invention is an improvement on the type of gas saving device described in the patent to Lampert 1,192,435, issued July 25, 1916, which patent provides for an article to be inserted between carbureter and the intake ports of an engine, the device including a metal plate member having a coiled spring cone mounted over an opening in the plate member, and having its base coil fixed t0 the plate member, the remainder of the cone being unattached and free to vibrate. In the Lampert device, the plate is of solid material; has the general contour of a gasket; and is used between adjacent flanges of pipe ends. The metal wall ofthe opening in the Lampert device is provided with an annular groove to receive and hold, by the expansive spring action, the largest or base coil of the spring cone.

The general object of the present invention is to improve on the Lampert type of device, and at the same time, retain the advantageous features of the freely vibratile spring cone.

One of the features of the invention relates to the improved means for so securing the base coil of the spring wire to the supporting plate that the coil cannot be loosened or separated accidentally from the supporting plate, due. to the vibrations of the spring or the jolting or vibration of the engine. Another feature is the combinationof the spiral spring with the standard asbestos copper gasket, su plemented and modified by the particular astening means for holding the spring over the gasket opening.

Another feature is directed to the particular shape and mounting of the spiral spring cone, which may be compressed to occupy the space of the thickness of the gasket or plate in the opening of which it is mounted. This design makes it possible to insert the plate or gasket and spring sidewise into position between adjacent pipe ends without necessitating the wide separation of the connection, it being merely necessary to loosen the connection sufficiently wide to insert the thickness of the plate or gasket. After such insertion, the spring cone is then free to assume its normal conical shape, and to serve in breaking up the incoming charge of the fuel mixture. This feature is particularly important because of the ease by which the device may be installed. By using an asbestos copper gasket of ordinary thickness, and having the cross-sectional diameter of the material of the spring no greater than the thickness of the gasket, the device may readily be inserted in any engine intake line without requiring modification of the engine parts.

The device of the present invention may be inserted at any connection between the carburetor and the inlet ports. Satisfactory locations have been at the engine and at the carbureter ends of the intake manifold. The apex of the cone may extend in-either direction, according to convenience, provided it does not interfere with the engine parts.

The above and other features and advantages of the device of the invention will be described and claimed in the following specification and claims, and illustrated in the accompanying drawing, in which:

Figure 1 shows a sectional view through a form of the device, including an asbestos copper gasket, in which an annular ring holds the lower and largest coil of the spring in its position adjacent the wall of the opening through the gasket. In this form, the ring is a separate member and extends from one face of the gasket through the opening and along side of the opposite gasket face;

Figure 2 shows, in section, the gasket illustrated in Fig. 1, but with the conical spring compressed into the plane of the gasket, illustrating the compressed position in which the device is adapted to be inserted between adjacent pipe and flanges;

Figure 3 represents a top plan view of the gasket and retaining ring, as shown in Fig. 1, but with the spring removed;

Figure 4L represents a top plan view of the conical spiral spring and gasket illustrated in Fig. l; and

Figure 5 represents a sectional View through one form of the device, showing the conical spring having its lower and largest coil held between opposite metal faces of an asbestos copper gasket, the in-' termediate asbestos portion being" spaced back from the central opening to provide space for the reception of the spring.

Referring in detail to the various'figures of the drawings, like numerals refer to like parts in the different figures.

1 is a spiral spring member formed in the shape of a cone, and so designed that it may be compressed to a plane having the thickness of a cross-section of the material. of the wire, as illustrated in Figure 2. The apex of the cone is indicated at 1. The base of the cone is formed by the largest coil or turn of the spring wire and is indicated at 1*. 2 represents a gasket member or plate upon which the spring 1 is mounted. and which serves to hold the spring in its operative position when installed in the intake line of aninternal combustion engine. 3 is a central opening in the member 2, and 4 indicates end slots or openings for the reception of fastening bolts or studs by which the member 2 and its adjacent pipe connections are secured together. The spring 1 is held in its mounted position with the axis of the cone in line with the axial center of the opening 3, and accordingly, thelargest coil 1 is held adjacent to the wall of the opening 3, or actually in' the same plane with the wall of the opening.

The invention provides several different specific constructions for securely holding the coil 1 in its position about the opening 3. In the sectional views of the drawing, the upper face of the gasket member is indicated at 2 and the lower face is indicated at 2 and the asbestos intermediateportion of the gasket is indicated at 2. The asbestos portion 2 may be cut back away from the central opening, thus providing an annular space between the faces 2 and 2", as indicated at 5. The largest coil of the conical spring 1 is shown held in this annular space by its spring action, which tends to expand the lower coil l against the material 2 Thus, the spring is held bythe material 2 laterally, and by the opposite metal material 2 and 2 on the top and bottom as shown in Fig. 5.

In the form illustrated in Figs. 1-4 inclusive, a separate element 6 is illustrated, as engaging the under face of the gasket, passing through the opening and then being recurved along the upper face. This particular holding means is thus formed as a ring having an annular groove, the side walls of which enclose the largest coil 1 of the spring cone, and also that portion of the gasket metal faces 2 and 2 next adjacent the central opening 3. In each of Figs. 1, 2 and l an opening 7 Will be seen, through which the upwardly extending spring projects. The opening 7 is preferably elongated in order to' prevent undue distortion of the curvature of the spiral spring. It is desirable also that the opening 7 extend through the thickness of the member 6, sufficiently deeply so that the coil of the spring projecting through the opening may be p ompressed to the plane of the gasket, as in in assembling the device, it is intended that the end of the larger coil of the spring cone be inserted into the opening 7 and the coil and gasket rotated with respect to each other, so as to thread the largest coil. 1 into and around through the space provided by the fastening member 6, the side faces 2 and 2 of the gasket and the asbestos material 2". In the arrangement shown in Fig. 5, the outward spring expansive action of the larger coil 1 serves to hold it in the annular space between the opposite faces of the copper portion of the gasket.

For the insertion of the combined spring and lgasket into position in an internal combustion engine, the invention contemplates the use of any neecssary device, such as a pair of pliers, by which the spring may be compressed to the thickness of the material of the gasketbythe same movement and by the same position of the implement which the operator uses in holding the gasket. If the place of installation be readily accessible, and the spring readil compressible, the operator may use his lingers in compressing the spring and slipping the device sidewise, or edgevvise, in between the adjacent pipe ends.

The curvature of the spirals of the spring should be so arranged that a line drawn through the material of" the spring at any point and parallel to the axis of the cone will not pass through the material of the next adjacent turn or coil of the spring, or any other portion of the spring. This description is presented as one way of stating thatthe conical spring may be compressed to a given plane Without distorting any'ofthe turns or coils of the spring in order toassume the plane position.

This'applicati'on is specifically directed to the particular compressible featureof the spiral spring. Claims to theuse of'-a"sep' arate part are presentedin my copending application Serial No. 594,216, filed October 12, 1922, from Which this application has been divided. Specific claims directed 'to theuse of an extended portion of the material ofone face of the gasket, as the part'for holding the spring, are presented in my 'cop'ending application Serial No. 601,282, filed November 16, 1922.
