UNITED STA-'TE JAMES HALL TAYLOR, OF OAK PARK, ILLINOIS METHOD 0F MAKING NOZZLES Application led April 11,

My invention relates to a new and improved method of making nozzles of the type commonly used in connection with steam boilers and consisting of a haring neck with a flange U at each end thereof.

The accompanying sectional drawings illustrate, step by step, a complete method, from billet to finished article, embodying my invention. l

In these drawings:

Fig. l'is a view of the original billet or blank; y

Fig. 2 is a view showing the billet between j the first set of dies; 15 Fig. 3 shows the beginning of the operation in the second set of dies; Y

Fig. 4 shows the second set of dies in mid position;

Fig. 5shows the second set of dies in final position; Y

Fig. 6 shows the added action of a shearing die .Fig 7 shows the beginning of the action in the third set of dies;

` Fig. 8 shows the completion of the action of Fig. 7, y

Fig. 9 shows the added action of a further die; and f Fig. 10 shows the finished article.

The original -wrought metal blank 11 is shown in Fig. 1. This blank is subjected to the action of the dies a; and illustrated in Fig. 2, the result being the formation of a circular body 12 with a V-shaped projecting flange comprising the innerportion 13, which is curved, the outer portion 14, which is preferably straight, and the flashing 15.

The billet is then placed in a circular die c, the effective internal diameter of which is substantially the same as the inner diameter of the flashing as indicated at w. This permits the shoulder which marks the periphery of the flange to be set down within the die c, as illustrated. The die Z moves relatively to the die c, downwardly as indicated by the arrows in Figs. 3, 4 and 5, the first result being the inward working of the portion 13 of the flange and the consequent upsetting at the junction between the

portions

13 and 14, as indicated in Fig. 4, this being due to the en- 1928. Serial No. 269,092.

gagement of the periphery of the flange portion 14 with the inside ,of the die c, the same being held appropriately in that position by the engagement of the flashing 15 with the v top of the die c.

The next result is the partial straightening of the flange, as indicated in Fig. 5, this being due to the continued movement of the die d and the engagement of the flashing 15 with the inner rim of the die c, some stretching taking place during this operation.

The next action is the bringing down of the shearing vdie e, as indicated in Fig. 6, the flashing 15 being taken off in this operation.

The billet is then inverted and placed upon the stool f of die g, as indicated in Fig. 7, the concentric female `die h being then brought down over the body of the billet so that the inner rounded portion lt. thereof will first engage the outside of the portion 13 of the flange. As this action continues the portion 13 and the junction between it and the portion 14 are stretchedsomewhat, and continued action brings the portion 14 down upon the face of the die g to complete the operation as indicated in Fig. 8.

With the dies g and z. in the position shown in Fig. 8, die z', shown in Fig. 9, is brought down upon the top of the body portion 12 of the billet to force the same into the annular recess t-2 in the die h, thus forming the flange 16.

The remaining central portion of the body 12, indicated at 17, is then punched out, and any flashing on the periphery of the flange 16 removed.

The result is the-finished article shown in Fig. 10, comprising the flaring circular neck 13, thelarge diameter flange 14y at one end thereof and the small diameter flange 16 at the other end thereof.

I claim:

1. The process of making nozzles, which comprises forming a circular body of metal with a circular projecting flange of V-shaped cross-section, and then, while maintaining the periphery of said flange, moving said body in a direction to move the outer portion of said flange toward position at right angles to the axis of said circular body of metal to swing the inner portion of said flange inwardly, and removing the central portion of the body.

2. The process of making nozzles, which comprises forming a circular body of metal with a circular projecting flange of V-shaped cross-section, and then, while maintainingthe periphery of said flange, moving said body in a direction to move the outer portionof said fiange toward position at right angles to the aXis of said circular body of metal to swing the inner portion orf-said flange inwardly and to upset said flange at the junction of the two portions thereof, and Vremoving :the central portion of the body.

3. The process of making nozzles, which comprises forming a circular body of metal with'a circular projecting flange of VV-shaped cross-section, and then, while maintaining the periphery of said flange, moving said 'body in the direction of the open side of the-l/-to bring the outer portion of said flange into rposition at right angles to the axis of said circular body of metal, to swing the inner fportion of said flange inwardly, and then to Qbring said outer portion into oblique position opposed to its original position, Aand .then applying inward pressure to said inner portion and bringing said outer portion into -position y,at right angles to said axis, and removing the central portion of the body.

4. The process of making nozzles, which comprises forming a circular body of vmetal with a circular projecting flangeofV-s'haped cross-section, and then, while maintaining the periphery of said flange, lmoving said body in a direction to move the outerportion of said flange toward position lat right angles to the axis .of said circular body of metal to swing the inner portion of said flange inwardly, then smashing down said body portion Vto form a second flange, and then removing the central portion of said body portion.

5. Theprocess of making nozzles, which comprises forming a circular body of rmetal with acircular projecting'flange of V-shaped cross-section, then placing the billet in an lannular die to maintain the periphery` of said flange ,and moving said body through `.said

Vdie while the periphery of said flangeis in engagement with .the inner rim ofsaid annular die, and removing the central portion Yof the body.

6.

7. The process of making nozzles, which Yment with said annular die and shearing 0E :comprises forming Va circular body of metal comprises forming a circular body of metal with a circular projecting flange of V-shaped cross-section having a ashing upon the periphery thereof, then placing the billet in an annular die with the periphery of said flange engaging the inner rim thereof and the flashing engaging the face thereof, and moving said body thronghsaid ydie while the periphery of said flange is Vin such engagesaid flashing -by,cooper ation between a shearmg die and said annular die, and removing .thecentra'l Aportion of the body.
