VALVE-STEM LUBRICATOR.
Specification of Letters Patent.
Patented July l, 1922.
[ '0 all whom it may concern: 1
Be it known that EARL E, PARSLOW is a citizen of the United States, residing at San Diego, in the county ofSan Diego and State of California, has invented a certain new and useful Valve-Stem Lubricator, of which the following is a specification.
My invention relates to a device for lubricating valve stems particularly the intake and exhaust valves for gas engines, and the objects of my invention are: First, to provide a device which will automatically lubricate the valve stems of gas engines; second, to provide a device of this class, which is applicable for use in connection with several makes of vehicles now in use; third, to provide a device of this class which communicates with the interior of the crank case for conducting air, laden with oil from the interior of the crank case against the valve stems in a position for efficiently lubricating the valve stems; and fourth, to provide a device of this class, which is very simple and economical of construction, durable, easy to install, automatic in its action and which will not readily deteriorate or get out of order.
With these and other objects in view, as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings, and to the characters of'reference thereon, which form a part of this application in which:
Figure 1, is a sectional view of a fragmentary portion of the conventional gas engine crank case and valve supports, showing the valves in elevation to facilitate the illustration and showing my lubricating device in elevation in operative position in connection therewith. Fig. 2, is a fragmentary side elevational view of the upper end of the lubricating device at a right angle to that of Fig. 1.
It will be noted that applicant has disclosed his device in connection with a dodge engine intake and exhaust valve construction, but it is obvious that the same construction may be used in connection with other engines of similar make of valve and valve operating structures.
My invention consists of a hollow lug bolt 1, provided with apertures 1 in opposite sides thereof communicating with the interior of said bolt. This bolt is threaded at its lower end and is positioned in a tapped hole in the crank case and positioned intermediate the intake and exhaust valve operating mechanism and positioned so that the apertures 1 face the valve stems on opposite sides, and is of sufiicient length so that the apertures are directly opposite the valve stems adjacent the valve stems support, so that air laden with lubricating oil is forces from the crank case through the hollow bolt and out through the apertures 1 against the valve stems, automatically lubricating the same with the operation of the engine, which is generally termed the breathing of the crank case.
In the installation disclosed herein the bolt 1 is substituted in the place of the ordinary lug bolt in a thread hole in the crank case and in this construction performs the double function of lubricating the valve stems and also serving as 2. lug bolt for supporting the lugs 2, so that it supports the valve operating plunger support by means of a nut 4:.
It is obvious however, that in case there is no lug bolt, a hole may be made in the crank case and tapped and the bolts inserted therein as shown and if desired the nut 4 may be used as a lock nut for preventing the hollow bolt 1 from turning.
Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the purview of my invention, the construction, combination and arrangement substantially as set forth in the appended claims.
It is obvious that with this construction, there is provided a means for lubricating the valve stems of gas engine by conducting lubricating oil saturated air from the crank case of the engine through the conductor and out through apertures in said conductor to a position where it most efiiciently lubricates the valve stems; that the place of lubrication, may be readily regulated by the length of the hollow bolt or the depth said bolt is mounted in the crank case; that it does not only lubricate the valve stems, but it automatically lubricates the operating plunger-s and provides support for the valve operating mechanism.
Having thus described my invention, what I claim new and'desire to secure by Let tcrs Patent is: V
1. A device o1 the class described, including the combination with a poppet valve stem of a gas engine valve, of a conducting tube communicating with the interior of the crank case at one end and its other end provided with air-aperture contiguous to the gaseng'ine valve stem. v
2. A device of the class described including, the combination with the intake and exhaust" valve of a gas engine of a conductor interposed between said valve stems and one end communicating with the interior of the crank case, its other end provided with oppositely disposed apertures facingtowar said valve stems.
3. A deviceof. the class described, including the combination with the intake and exhaust valvesof a gas engine of a conductor interposed between said valve stems and its one end communicating with theinterior of the crank case, its other end provided with oppositely disposed apertures facing toward said valve stem, comprising a hollow bolt threaded at one end, screwed in a threaded hole in the crank case anditsextended end provided with apertures communicating with the interior of saidbolt.
v In testimony whereof, I havehereunto set my handat San Diego, California, this 29th day of April 1921.
