A. M.' SEARLES ET AL VALVE AND THE METHOD OF MAKING IT Fled Dec.l 1, 1922 Patented Nov. 4, 1924.
AAR/ON M. SEARLES, OF CHICAGO, AND FORE BAIN, F LA. GRANGE, ILLINOIS; SAID PATENT OFFICE.
BAIN ASSIGNOR TO SAID SEARLES.
VALVE.AND THE METHOD OF MAKING IT.
Application filed December 1, 1922. Serial No. 604,316.
To all whom. t may concern:
Be it known that we, AARON M. SEARLEs and FORE BAIN, citizens of the United States, respectively residing at Chicago, in the county of Cook and State of Illinois, and at La Grange, in the'county of Cook and State of Illinois, have invented certain new and useful Improvements in Valves and the Methods of Making Them, of which the following is a specification.
This invention relates to valves and the 'method of making them.
One of the objects of the invention is to make a light, elastic, poppet valve.
Another object is to make a valve substantially unaffected by -high temperature;
that will not warp and which is substantially non-corrosive and non-oxidizable.
A further object is to make a valve with an elastic rim seat.
A further "object is to provide a pcppet valve, which, having an elastic rim, tends to increase its diameter by force of explosion or internal pressure.
A further object is to provide improved means for securing the Valve to the valve stem.
Another object is to provide a valve which has substantially no aiiinity for free carbon and which will not accumulate deposits of carbon on its working surfaces.
Other objects and advantages will readily appear to persons versed in the art, from a consideration of the following description, when taken in conjunction with the drawings, wherein Fig. 1 is a central vertical section thru an embodiment containing the invention.
Fig. 2 is a modification of Fig. 1.
Fig. 3 is a rod of which the valve stem is to be made. 4
Fig. t shows the rod after `one end has been upset to provide an enlargement of which to construct a shoulder.
Fig. 5 is a finished valve stem ready to be inserted in the valve and to be secured thereto.
Fig. 6 is a plan view of the valve before being fastened to its stem.
vide a central disk part 11 and a surrounding In all the views the same reference charac-l rim part 12-12, thus making the valvecupshape with an outwardly flaring rim, as shown in Fig. 1 or an inwardly converging rim, as shown in Fig. 2.
In Fig. 2 the valve seat 13 is slightly more acute than the confronting valve surface to produce the above described effect.
Washers 15V-15 are used to reenforce the disk or body part of the valve. The stem 16 is preferably secured to the valve and washers by upsetting the end of the stem by application of pressure while theend of the stem is hot.
A rod 17 is cut to suitable length, then one end is upset to provide the enlargement 18. The enlargement is then reduced to provide the shoulder 19 and the reduced tenon 20. The tenon is left longer than to merely extend thru the valve and washers, as shown in broken line in Fig. 1, so that it may be subsequently upset to increase its diameter and to fully fill the angular or irregular axial hole in the valve and the washers.
The valve 10 and washers 1515 each have an axial perforation 22, which is irregular in outline, that is to say, it is not truely Y round so that when part of the tenon 'completely lls these openings, as when the tenon 1s upset therein, the stem is thereby prevented from rotating. As the valve wears at its rim edge, or when pressure is applied to it, the rim is contracted thereby and larger surfaces of the valve and the valve seat are brought into intimate contact.
The valve, made as described, is light, has little inertia and momentum and is especially ada table for high speed engines. l
avinlg described our .invention what we claim as new and desire to secure by Letters Patent, is l,
1. In combination with an inwardly tapered substantially unyielding valve seat, a hollow cap shape poppet valve having its perimeter tapered at a diderent angle from a common axis from that of the seat so that the outside end surface of the valve, near its free edge, contacts the valve seat first in closing the i valve 4and increased pressure 4tends to increase the contacting area of the valve with its seat. v
2. In combination with an interiorly-l and inwardly tapered, substantially rigid valve seat; a valve comprising a 'diskin a singlev plane, perpendicular to its axis of movement, and terminating in a yielding annularange,
tapered to a different extent to said axis than the aforesaid seat, whereby increased pressure on said valve tends to increase the contasting surface area of said valve and seat.
In testimony whereof We hereunto set our hands.
AARON M. SEARLES. FORE BAIN.
