a WILLIAM H. SPIKE, OF CLEVELAND; OHIO, ASSIGNOR TO THE STEEL PRODUCTS COM- PANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.
. VALVE-MAKING PROCESS.
' Application filed October 28, 1922. Serial No. 597,485.
' To all whom it may concern: 1
Be it known that I, WILLIAM H. SPIRE, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State 5 of Ohio, have invented new and useful 'Improvements in Valve-Making Processes, of whichathe following is a specification y'the principle of the invention being herein explained, and the best mode in which I have 10 contemplated applying thatprinciple, so as to distinguish it from other inventions.
My invention relates to valve-making processes, its object being to producea valve in a simple and economical manner. I
Said invention consists of a process hereinafter fully described and specifically set forth in the claims.
More particularly, my improved process consists in taking a rod having a diameter substantially equal to the diameter of the required valve stem, upsetting the end of such rod to form an enlargement, welding to the latter a blank, upsetting such blank and upset rod portion to form a rough head,-
and then finishing the stem and head.
The annexed drawing and the following description set forth in detail a certain process embodying my invention, the disclosed process, however, constituting but one of various processes in which the principle of the invention may be employed.
In said annexed drawing:
Fig. 1 represents aside elevation of a blank for forming the valve-stem.
Fig. 2 represents a side elevation of said stem with its stem upset, in conjunction with the head-forming blank before being welded.
Fig. 3 represents a side elevation of the stem and head-forming blanks after having been welded.
Fig. 4: represents a side elevation of the welded stem and head blanks, after the welding-fin has been sheared off.
Fig. 5 represents a side elevation of the structure after the head blank has been upset to form a rough head.
Fig. 6 represents a side elevation of thefinished valve.
In carrying out my improved process,;[ first take a cylindrical steel bar or rod 1, Fig. 1, having a diameter but slightly larger and hence approximately equal in diameter to that of the required finished valve stem,
ment 2. This upsetting is done when the metal is cold if the character of such metal permit, as for instance in the case of cold drawn carbon steel, but must be done hot where the metal upon cooling becomes too hard to be upset cold as in the case of an alloy steel such as chrome-nickel steel: To the end of this enlargement I then electrically weld a cylindrical steel blank 3 of substantially the same diameter as that of the enlargement 2-, Fig. 2, during which process a welding-fin 4 is formed, Fig. 3. This fin is then sheared off, by suitable means, either hot or cold, according to the character of the steel or machined or ground oil. When an alloy steel such as nickel steel is used for the head, the fin may be sheared cold, but when an alloy steel such as chrome-nickel steel is used, it must be reheated before shearing, as the latter steel becomes upon cooling too hard for shearing. If the fin is to be machined or ground, the head is first annealed.
After the said fin has been removed, the head portion of the structure is then heated and forged ,or cold upset to form a rough head as shown in Fig. 5. Where the character of the steel is such as may require it, the rough valve is now heat-treated. It is then machined to form the finished valve as shown inFig. 6 after which the outer end of the stem is hardened to resist wear, as is customary.
What I claim is:
1. The process of making a poppet valve, which consists in taking a rod having approximately the diameter of the required valve stem; upsetting one end of said rod; welding a blank to such upset portion; upsetting the said upset portion and blank to form a rough valve head; and then finishing the head and stem.
2. The proces of making a poppet valve, which consists in taking a rod having approximately the diameter of. the required stem; upsetting one end of said rod while cold; welding a blank to such upset'portion; upsetting the said upset portion and blank to form a rough valve head; and then finishing the head and stem'. v
3. The metMd of making a poppet valve,
g L Meegeee which consists in takin I a rod having blank and enlargement to form a roligh a dm-meter approximate y equal to the valve head; and then finishing said stem and diameter of the required valve stem; uphead. setting one end of sald rod to form an Signed by me this 26th day of October,
5 enlargement; welding to the latter a blank 1922. M
having a diameter substantially equal to that of said enlel geinent; upsetting said" I WILLIAM lBL'SPJURE.
