UNETE STATES VIOLA noor CAMERON, or NEW YonK, N. Y.
FUEL-GHARGE-TREATING- DEVICE.
Original application filed October 12, 1922, Serial No. 594,216. Divided and this application filed November 16, 1922. SeriatNo. 601,282.
T all whom it may concern:
Be it known that I, VIOLA Roo'r CAMERON, 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.
This invention relates to gas saving devices for internal combustion engines, and pertains particularly to devices forbreak- 'ing 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 525, 1916, which patent provides for anarticle to be inserted between a carburetor 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 (oil fixed to 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 of the 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 ofthe 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-sup= Another feature is the combination of the spiral spring with the standard. asbestos copper gasket. supplemented "and modified by the particular fastening means for hold-' ing the spring over the gasket opening.
Another feature i '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 itis mounted. This design makes it possible to insert the plate or gasketan d 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 carbureter 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 direc-' ,tion, accordlng to convenlence, provided it does not interfere with the engine parts.
The above and other features and advantages of the device ofthe invention will be described and claimed in the following specification and claims, and illustrated in the accompanying drawing, in which:
Figure 1 represents a sectional view of the combined asbestos copper gasket and spring, in which one face of the metal portion of the asbestos copper gasket projects centrally and then axially through the opening and'is recurved about the largest coil of the spring and alongside of the opposite face of the gasket; I Figure'2 represents a top plan view of the gasket and retaining ring, as shown in Figure 1, but with the spring removed;
Figure" 3 represents, in section a modification of the form illustrated in Figure 1, the spring retaining means being formed of a plurality of eyelets, struck up from the material of one face;
Figure 4 shows, in section, the gasket illustrated in Figure 1,"but with the con ical spring compressed intothe plane of the gasket, illustrating the compressed position in which the device is adapted to be inserted between adjacent pipe and flanges;
Figure 5 represents a top plan view of CJi the asbestos copper gasket, shown in Figure 3, illustrating one of the eyelets projecting centrally prior to being recurved about the largest coil of the spring member; and
Figure 6 represents a 'topplan view of the conical spiral spring removed from the gasket and retaining member. I
Referringin vdetail to the various figures of the drawings, like numerals refer to like parts in the different figures l 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 4. The apex ofthe 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 an internal combustion engine. 3 is a central opening in the member 2, and 4 indicates end slots or openings for the reception of fastening belts 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, the largest coil 1},- is held adjacent to the wall of the opening 3, or actually in the same plane 'iiiththe wall of the opening.
The invention provides several different specific constructions for securely holding the coil 1 in its position about the opening 8. 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 asbestosintermediate portion of the gasket is indicated at 2 The asbestos portion 2 may be cut back away trom the central opening thus providing an annular space between the faces 2 and 2", as
indicatedat 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 1 against the material 2. Thus, the spring is held by the material 2 laterally, and by the opposite metal material 2 and 2 on the topand bottom, in addition to the particular retaining member which will be described.
In the views illustrated in Figures l. 2
- and 4., the retaining element 6 is for'med by extending spring projects. Theopenine 1 is preferably elongated in ordeetopreventan extension of the under face of the copper portion of the gasket, which will be seen as extendingcentrally, thence through the opening, and thence being received along side of the opposite 'tace 2.
In each of Figures 1, 2'aiid t, an opening 7 will be seen. through which the upwardly the member 6, sufiiciently deeply so that the coil of the spring projecting through the opening may be compressed to the plane 01? the gasket, as in Figure 4.
In the modification illustrated in Figures 3 and 5, the under face of the copper portion of the gasket is extended inwardly to form a plurality of eyelets 8 adapted to be curved upwardly through the opening 3 and thence along side of the opposite face of the gasket. T his arrangement is substantially similar to the arrangement illustrated in Figures 1, 2 and 4 except that the eyelets are formed separately instead of as one continuous portion. In Figure 5, the length of one eyelet member is shown as fully extended centrally, and prior to the recurving of it into the eyelet shape.
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, 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 form shown in Figures 3 and 5, the eyelet members may be bent up and reciirved around the largest coil 1 of the wire, or the end of the largest coil may be threaded through the plurality of eyelets in substantially the same manner as provided for in Figures 1, 2 and 4:;
For the insertion of the combined spring and gasket into position in an internal combustion engine, the invention contemplates the use of any necessary device, such as a pair of pliers, by which the spring may be compressed to the thickness ot the material of the gasket by the same movement and by the same position ot the implement which the operator uses in holding the gasket. It the place of installation be readily accessible, and the spring readily compressible, the operator may use his fingers in compressing the spring and slipping the device 'sidewise, or edgewise, in between the adjacent pipe ends.
The curvature of the spirals of the spring should hey 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 that the conical spring may be compressed to a given plane without distorting any of the turnsor coils of the spring in order to assume the plane position.
This application is specifically directed to that form of the invention in which the material; of" one. face of the gasket extended and used as the spring holding member. Claims to the use of a separatepart are presented in my copending application Serial No. 594,216, filed October 12, 1922, from which this application has been divided. Specific claims to the spiral spring are presented in my copending application Serial No. 601,283, filed November 16, 1923.
