CHARLES A. DIES, OF CHICAGO, ILLINOIS.
MANUFACTURE OF PIPE-FITTINGS.
SPECIFICATION formingpart of Letters Patent No. 691,454, dated January 21, 1902.
Application filed September 19, 1900- RenewedMay 24:, 1901, Serial No. 611804. (Model) T0 [LZZ whom, it may concern:
Beit known that I, CHARLES A. DIES, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and usefullmprovementsin Methods of Manufacturing Pipe-Fittings, of which the following is a specification.
The present invention relates to a method of manufacturing pipe-fittings of wrought metal.
The object of the present improvementis to provide a simple, economical, and effective method of manufacturing gas, steam, and other like heavypipe fittings and with which in the formation of the lateral neck or necks of the fitting the metal of the main body of the fitting is upset in an endwise direction to aiford the required amount of metal in the operation of forming such lateral neck or necks upon such main body of the fitting, all as will hereinafter more fully appear, and be more particularly set forth in the claims.
In the accompanying drawings, illustrating an apparatus for carrying out the present improved method of manufacture, Figures 1 and 2 are central sectional elevations of the dies and formers adapted to make an ordinary T-fitting, the parts being shown in the two intermediate positions between the initial and the finat position of the parts; Fig. 3, a sectional elevation of the fittingblank in its original condition; Fig. 4, a similar view of the same in a partially-formed condition; Fig. 5, a similar view of the same in a rough-finished shape ready for final finish; Fig; 6, a similar Viewof the fitting in its finished condition.
Similar numerals of reference indicate like parts in the several views.
Referring to the drawings, 1 represents the blank from which the fitting is to be formed in the present process of manufacture, and which blank consists of a section of tubing having a length sufi'icien't to afiord the necessary metal for displacement in the formation of the usual lateral neck or necks of the pipefitting in the present method.
The combined blank-holder and formingdie of the present apparatus consists of two or more substantially counterpart sections or members 2 and 3, the divisional line of whichmay be in a vertical plane intersecting the axis of the cylindrical forming-punches of the apparatus. The interiors of such die-sections are recessed out to correspond with the outer configuration of the particular pipe-fitting to be manufactured.
4 is the stationary forming core-piece or abutment, which in the present construction of apparatus is formed with a cylindrical portion 5 of a diameter equal to that of the bore of the pipe-fitting to be manufactured, a cylindrical intermediate portion 6 of a diameter equal to the outer diameter of the pipe-fitting and filling an end of the main bore of the forming-die, and with an enlarged outer end or main portion 4, adapted to abut against an end of the forming-die, as shown in Figs. 1 and 2. In the construction shown the end surface of the shank portion 5 is flattened to form a track, upon which moves the forming sphere or ballhereinafter described, While the shoulder or offset formed by the junction of the shank 5 and cylindrical portion 6 is adapted to form an end abutment for the next adjace nt end of the fitting-blank 1, as illustrated in Figs. 1 and 2.
7 is the movable forming punch or plunger, formed like the core-piece or abutment 4, with a corresponding cylindrical shank 8, fitting the bore of the fitting-blank 1, with an intermediate cylindrical portion 9, of a diameter equal to the outer diameter of the pipe, fitting and filling the other end of the main bore of the forming-die, and with an enlarged outer end or main portion 7, adapted to contact against an end of the forming-die, as shown in Fig. 1, so as to limit the inward movement of the forming-plunger. In like manner the shoulder or oifset formed by the junction of shank 8 and the cylindrical portion 9 is adapted to form an end abutment for the next adjacent end of the fitting-blank 1, as illustrated in Figs. 1 and 2, to force or upset the same inwardly in the first or initial swaging or upsetting action of the present method of manufacture, while the inner end of the cylindrical shank is beveled off to form an inclined surface adapted to engage the forming sphere or ball 10 to force the same laterally upon an inward movement of the movable plunger 7 10 represents the lateral neck forming spheres or balls, usually two in number, and having a diameter equal to the internal diameter of the lateral neck to be formed on the pipe-fitting, and which forming balls or spheres are adapted to be forced laterally by the inclined end of the shank of the movable plunger 7.
In the present manufacture the Wall of the blank will not afford metal sufficient to be drawn into and form the lateral neck or necks of the fitting, and accordingly the present invention involves as avery material feature thereof a combined drawing action by means of the forming-spheres 10 and an upsetting action upon the end of the tubular blank 1 by means of the shouldered extension 9 of the forming-plunger 7 to force or upset sufficient metal toward the central part of the fitting undergoing manufacture and supply the necessary amount of metal required in forming the lateral neck or necks of the pipefitting.
The operation of the present apparatus in detail comprises the following proceedings: The blank 1 is introduced into the bore of the forming- die members 2 and 3 and the-stationary core-piece 4 inserted in place, as well as the movable plunger 7, with a forming-sphere 10 between said last-mentioned members L and 7. With the application of the proper force to the movable plunger 7 the forming-ball is forced laterally to form an enlargement upon the side of the blank 1, as illustrated in Fig. 1. Simultaneously with the formation of such enlargement the metal of the blank is upset toward the center of the blank to afford additional metal for the formation of such enlargement-of the required thickness. It has been found from practical experience with the present method that with the blank in a heated condition, usually a red heat, the lateral drawing action above described will absorb nearly the whole of the metal, which is simultaneously upset toward the center of the blank, and that but a very slight thickening of the blank opposite said lateral enlargement will take place, and which thickening can be left in the fitting or subsequently removed in the final finishing operation upon the blank, as the judgment of the manufacturer may suggest. The next step will be the formation of an orifice 11 by any usual means in the crown of the enlargement, as shown in Figs. 2 and 4, a backing out of the plunger 7, and the introduction of a second formingsphere behind the sphere already in use, in manner clearly indicated in Fig. 2. With a second inward stroke of the plunger 7 the two forming-spheres 10 10 are forced laterally and the lateral enlargement is spread to form a lateral neck 12, having a bore of the required diameter, the blank as so formed being illustrated in Fig. 5. The blank thus formed can then be trimmed off and otherwise finished in any usual and suitable manner that the judgment of the manufacturer may dictate.
It is evident that with very slight modification of the operative parts of the apparatus herein illustrated the same can.be adapted to manufacture pipe-fittings of the cross and similar types.
Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is
1. The herein-described method of manufacturing wrought-metal pipe-fittings, which consists in forming in the side of a tubular blank a hollow lateral enlargement, and during such formation of the enlargement upsetting the blank endwise to afiord the amount of metal necessary to form such lateral enlargement of the required thickness, substantially as set forth.
2. The herein-described method of manufacturing wrought-metal pipe-fittings, which consists, in forming on the side of a tubular blank a lateral enlargement and simultaneously upsetting the tubular blank endwise to afford the amount of metal necessary to form such lateral enlargement of the required thickness, forming a perforation in the crown of such enlargement, and finally spreading the said enlargement into the form of a lateral neck upon the main body of the fitting, substantially as set forth.
Signed at Chicago, Illinois, this 15th day of September, 1900.
