c. c. ANDERSEN SELF CLEANING VALVE STEM Filed June 27, 1922 :Patented Mar. 16, 1926.
UNITED STATES CHRISTOPHER c. nivnnasnlv, or saL'r LAKE CITY, wean.
SELF-CLEANING- VALVE STEM.
Application filed June 27, 1922. Serial Nair/1,126.
To all whom it may concern:
Be it known that I, CHRISTOPHER C. AN- nnnsniv, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented a new and useful Self-Cleaning Valve Stem,
of which the following is a specification.
This invention relates to means whereby the valve stems of internal combustion en gines can be rendered self cleaning. a
. It is a well known fact that in engines of the type mentioned the stems of the valves controlling the exhaust ports soon become covered with deposits of carbon which interfere with the free working ofthe valves and cause the stems to stick.
It is an object of theinventi'on to combine with the valve stems a means whereby the carbon deposits are prevented from forming on the stems and said stems are thus left free to work freely at all times.
A further object is to provide a self cleaning attachment which can be applied to stems already in use or can be used in connection with stems prepared especially to receive the same.
IVith the foregoing and other objects in view which will appear as the description proceeds, the invent-ion resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made Without departing from the spirit of the invention.
In the accompanying drawings the preferred forms of the invention have been shown.
In said drawings Figure 1 is a section through a portion of an internal combustion engine and showing the exhaust port with a valve therein provided with self cleaning means such as constitutes the present invention.
Figure 2 is a similar view showing a slightly modified arrangement of parts.
Figure 3 is a plan view of a modified form of cleaning member, the valve stem being shown in section.
Figure 4 is a section on line ell, figure 3, the stem being shown in elevation.
Figure 5 is a section through another modified construction.
Referring to the figures by characters of reference 1 designates a portion of an engine structure having an exhaust port 2 adapted to be closed by a valve 3 the stem of which has been indicated at 4 and which is slidable within a suitable guide sleeve 5 or the like. This guide 5 extends into the bore 6 formed at the port 2 and constitutes a stop or abutment for a cleaning disk 7 loosely mounted on the stem 4. A spacing sleeve 8 is mounted on the stem 4 between the disk 7 and the valve 3 and constitutes another stop or abutment for the disk 7 Obviously during the reciprocation of the valve 3 as the engine operates, the disk 7 will be moved upwardlyv and downwardly with the stem eland will be brought to a stop successively by the end of the guide 5 The spacing sleeve Sis used where the washer 7 is to be combined with a valve stem already in use. If the stem is constructed for use in connection with a self cleaning disk, it can be formed with an annular flange 9 constituting a stop, as shown in Figure 2, thus doing away with the separate sleeve 8. The cleaning disk 10 corresponding with the disk"? is interposed between the flange 9 and the guide 11 shown in Figure 2.
- Instead of providing a plain disk such as shown at 7 and 10 the disk can be formed with radially extended blades 12 as shown 'in Figures 3 and 4. Thus when the disk is reciprocated by the action of the valve stem, the disk will not only scrape deposits from the stem but also will be given a whirling action by the gases, thus operating more efficiently to clean the stem than would be the case otherwise.
In Figure 5 the guide 13 has been shown provided with a bore 14 extending into one end thereof and closed by a gland 15 screwed into said end. The stem 16 of the valve 17 extends longitudinally of the bore 1 1 and has a cleaning disk 18 loosely mounted thereon and adapted to work between the gland 15and the inner end of the bore 14-. By providing a disk at this point thatportionof the stem Within the guide 18 will be cleaned.
It will be apparent that by utilizing cleaning means such as have been described,
' the formation of carbon deposits on the 5 including an exhaust port having a valve seat in its lower enth of :1 valve movable iqnvardl against the seat to close the port, an upwardly extending; stem projecting: from the valve and through the port a W cleaning; disk loosely mounted on the Stem above the valve and Within the port, said disk adapted to slide and rotate freely upon the stem, and means on and movable with the stem between the valve and disk for liniiting the movement of the disk in one direction relative to the stem.
In testimony that I claim the foregoing as my own, I have hereto aflixed my Sig" nature.
CHRISTOPHER C. ANDERSEN.
