f yPatented Feb. 25,151930 d UNITEDSTATES,PATENT OFFICE l JAMES HALL TAYLQR, or CHICAGO, ILLINOIS PROCESS OF MAKING N'OZZLES a Application filed June 2.6, 1925. Serial No. 39,794. y
' My invention relates to nozzles such as are commonly used in connection with steam boilers and the like, and contemplates a new and improved process of making them. p
v*In the accompanying drawing the'successive figures .illustrate the ksuccessive steps in the process of my invention, although it will appear that the precise order of the steps, at
v rleast as to some of them, may be varied, and
ythe appended claims have been drawn accordingly.v The figures are all cross-sectional views, with the exception of Figure 5, which is a plan view ofthe billet in the form shown iny Figure 4. y
In the drawings:
' Fig.'1lis a cross-sectional view'through a billet from which a nozzle is to be made; f
` billet is heated to aworking heat and, as shown Figs. 2, 3 and 4 are cross-sectional views through the dies and the billet, illustrating successive steps of my process;
Fig. 5 is a plan view of the billet, partially formed into la nozzle, shown in Fig. 4
.F ig. 6 is a cross-sectional view through the ypartially formed nozzle of Fig. 5, after it has been completely pierced; v
Fig. 7 is a cross-sectional view through the partially formed vnozzle after the upper flange has been formed thereon;
' Fig. 8 is a cross-sectional view throughthe completed nozzle, showing the lower flange shaped to fit a boiler or` like structure.
The billet of wrought metal, fromv which the nozzle is to be formed, is shown at a. This acircularfbody e having avflange f at the bottom thereof. A die blockg disposed in the centerof the face of the lower die d forms a central depression k in the bottom of the body vthe completed nozzle.
e. In this first step, the body e is formed to to approach each other as indicated in Figure 4. In this action, the metal tends to flow laterally, but is so confined by die 0 that 'its only avenue of owis downward between die 'c and die block z'. Consequently,'the metal `flows counter to the .movement of the dieblock c', as will be clear from the illustration, the body e being thus elongated to the proper length, the flange leaving contact with ythe die c, and a nearly through central opening s formed, only the thin wall m remaining at the. top of the central opening.
, Figure 5 is a plan view of the billet formed to this point.
The next step in the process is to remove the ythin wall m, resulting in the formation illustrated in Figure 6, with the through cen- .y tral opening s".
The next step in the process is to form the vperipheral groove o, whereby an integral structure comprising an upperflange t, a lower flange f, and a connecting neck e is formed,
tween dies to insure the form of the flanges.
In this action the billet may lengthen slightly and the action villustrated in Figure 4 may, tliereforabe calculated to make allowance accordingly, so that the inished product will be of the right length. The groove o may also be formed by cutting in a lathe, in which event the nozzle length is finally determined in the formation yillustrated in Figure 4.
The last step in the lprocess is to bend the lower flange into cylindrical form, as shown in Figure 8, sothat it may properly t the boiler or the like to which it is to be secured.
I claim :f l. The process of forming nozzles which comprises first forming a circular body with a flange at one end, then forming a depression in the center of said body substantially through the same, and thereby causing said body to lengthen, then forming a peripheral groove in said body by reducing it adjacent said flange to form a neck, leaving an opposing flange of the diameter of the originaly circular body, and removing the metal at the end of said depression to rform a through.
opening.
2. The process' of forming nozzles which comprises first forming with male and female dies a circular body With a flange at one end, then'forcing a die into the center of said body While in said female die alone to form a deep f central depression and thus securing an eX- tending action lengthening said body, removing the remaining metal closing said depression to form a through opening, and there# after forming a peripheral groove in' said body adjacent said flange to form a neck and an opposing flange. 3; The process of flange, then forming a depression in the center of said body nearly through the same and thereby causing said body toA lengthen, then forming a peripheral groove in said body by reducing it adjacent said first named flange to form a neck and said opposing flange, and removing the metal atthe end of said depression to form a through opening. y
' 4. The process of forming anozzle which comprises forming a body with a central hub and a flange at one end, thensubstantially piercing the body and simultaneously eXtruding the hub, then reducing the hub adjacent the iange to form a neck With a smaller opposing flange, and completing the piercing of the body.
5. The process offforming a nozzle from a blockwhich comprises die pressing the block to flow the metalI into a central hub anda laterally extending flange, said flange being substantially finished by said operation, then [substantially piercing and extruding the hub and flange to form the hub to substantially its final outer diameter, then reducing the hub to leave a second `flange on the outery end of the hub, and completing the piercing to form a throughy opening.

.In Witness whereof, I hereuntojsubscribe 10th dayofJune,1925. JAMES 'HALL TAYLOR;
