METHOD OF MAKING qocxs OR VALVES Filed May 5. 192a FIE-1 A F75. Y 7 I aaozntoz .7 17- B/mwwfi- Patented Sept. 29, 1931 UNITED STATES PATENT OFFICE JOHN D. BALDWIN, 33., OF CLEVELAND, OHIO, ASSIGNOR TO ALBERT J. WEATHER- HEAD, JR., OF CLEVELAND, OHIO mmnon or MAKING cocxs on VALVES Application filed May s, 1928. Serial No. 274,705.
Lect of the invention is to produce a valve ody in a facile and inexpensive way by automatic machinery, using drawn or extruded brass rods or bars of special formation. As an exemplification of one form of article which can be made in that way, see the accompanying drawings, in which Fig. 1 is a perspective view of a rabbeted rod which is partly round and partly rectangular, and from which a valve body may be readily produced. Fig. 2 is a sectional view and side elevation of the same rod with a valve body partly produced thereon. Figs. 3 and 4 are side and end views of the valve body shown in Fig.
i 1, but severed from the rod. Fig. 5 is a side view of the valve body, and Figs. 6, 7 and 8, are sectional views thereof, illustrating four successive steps in the production thereof after it has been severed from the rod. Fig. 9 is a sectional view, on .a larger scale, of the valve body as it appears after the last or 11nishing step. Fig. 10, is a sectional view, of the finished valve body and a screw-valve member, assembled. Fig. 11 is a sectional view of a modified form of rod stock.
In practicing this method, a brass rod or bar A of a predetermined cross sectional shape is first produced or provided. This rod or bar may be of extruded stock, or stock formed into the desired cross sectional shape by drawing, rolling or in any other suitable way. As an exemplification of two cross sectional forms of rod which may be used to produce an angular valve body B, simply and cheaply, reference may be had to Figs. Land 11 in the drawings. In Fig. 11 the rod is of key-hole shape in cross section, and in Fig. 1, the rod is of corresponding shape, that is, it if of reduced width or rabbeted lengthwise at 2-2 to provide a narrow flange, rib or exan angular valve body as hereinafter set forth.
Thus, rod A is introduced into and fed through a collet in an automatic screw machine, the enlarged body portion 4 of the rod being fed axially through the collet with the angular rib or rabbeted portion 3 off center in respect to said axis. The end portion of the rod is then turned down to two different diameters at two separated places to provide a large cylindrical extension 5 and a smaller cylindrical extension 6axially of the larger body portion 4 of the rod. The stock intermediate or between the two cylindrical portions 5 and 6 retains the contour or shape of the original rod, but while the rod is still held in this same automatic screw machine, the outer or larger cylindrical extension 5 is drilled substantially its full length and the outer corner edge of the drilled opening 8 is chamfered. These operations being completed the larger extension 5 is threaded, preferably with a die, and the smaller cylindrical portion 6 is also threaded, preferably severed or cut oif.
The next step involves the placing of the cut-off section or valve body B (see Fig. 3) within the chuck or-collet of a second automatic screw machine to permit operations to proceed on the squared or angular projection 3' which extends from the middle of body B at right angles to the cylindrical portions 5 and 6. Then the angular projection 3' is turned round (see Fig. 5) and at the same time drilled to different diameters. thereby providing an annular valve seat 9 at the intersection of a small bore 10 and a larger counterbore or entrance 11, see Fig. 6. The round proieotion 3' is then threaded on the outside, and the counterbore 10 tapped, see Fig. 7. A round hole 12 is then drilled axially within the smaller cylindrical extension 6, see Fig. 8.
The next operation consists in placing the product of the aforementioned steps in a machine which drills two round communicating holes or passages 14 and '15 in body B be- 14 and 15' are drilled in opposite directions.
tween the inner ends of the drilled openings 8 and 12 andthe opposite sides of bores '11 and 10, respectively. The holes 14 and 15 are drilled at an inclination relatively to the axes of end openings 8 and12 so as to communicate with bores-11 and 10 above and below the valve seat 9. Preferably, the angle holes simultaneously, but'they can be drilled in a drill press separately at increased production costs.
The valve body per se is now com le'ted, and a valve member C havlng a screw-t readed stem 16 and a handle 17 may be screwed into the screw-threaded bore 11, and a packing nut or cap 18 may be screw-connected with the external screw-threads on the side pro ection or extension 3, as delineated in Fig; 10,
thereby completing the valve.
The steps taken to produce a finished valve body from solid rod stock are rapidly and accurately performed, and the cost of production of a shut-off cook or valve made in the way described is greatly reduced compared with other methods and practlces known to me, and furthermore, the product itself is exceptionally sturdy and satisfactory for the purposes intended, especially in the diminutive sizes which are used extensively with copper pipes of small diameter, for example, with the relatively small air and gasoline feed pipes used generally in automobiles.
What I claim is: l
1. A method of producing a valve body, which includesthe steps of forming a reduced cylindrical'portion off center in and lengthwise of a rod, and of severing from the main body of the rod a section thereof adjacent to and including said cylindrical portion.
2. A method of'producing a valve body from a rod or bar of varying width in cross section, which includes the formation of a reduced cylindrical portion longitudinally in the wider part of the bar, and the production from the narrower part of thebar of a cylindrical extension at right angles to the axis of said bar.
3. A method of producing an angular body from a rabbeted rod or bar, which includes the step of forming cylindrical portions at spaced intervals lengthwise of the bar in the main body of the bar, and of producing a cylindrical extension at right angles to said main body in the rabbeted portion of the bar intermediate said cylindrical portions.
4. A method of producing an angular body consisting in machining a section of a rod at spaced intervals lengthwise of its axis and eccentric thereto to a cyliiidrical form, in turning the unmachined portion of said severed part to a cylindrical form around.an axis at right angles to the main axis of the severed part, and in drilling separate openjunction with the main body of the rod; in
turning and screw-threading the angular projection'; and in drilling communicating passages at different angles through said cylindrical portions and'angular projection.
6.
