METHOD OF MAKING GIilNERA'lOR TUBES.
Application filed May 31, 1927.
This invention relates to a new and. improved. method for making generator tubes.
Tn generator tubes for gasoline stoves, it has been in usual practice heretofore to form these tub-es in a n'ianner which was relatively dil'licult to follow and which was expensive.
This invention is designed to overcome the defects noted above, and objects of such invention are to provide a novel method of forming a generator tube and a novel tube produced by such method which is free from any welded joints or other portions formed of dillierent members, but which is integral throughout, and which although integral is nevertheless accurately shaped in accordance with the conventional contour of these generator tubes.
An embodiment of: the invention is shown in the accompanying drawings in which:
Figure 1 shows one step in the process of making the tube;
Figure 2 shows the next step;
Figure 3 shows a successive step;
Figure 4 shows the finished tube.
Betcrring to the drawings, it will be seen that a tube 1 is cut to the desired length. This tube is termed of suitable inz'lterial and of' the requisite bore. The tube, after having been cut to length, is spun or otherwise formed adj scent one end to provide a constricted. portion 2. or a portion of sn'ialler diameter than the main body of the tube and to :li'orrn a second or outer constricted portion 3 ol still smaller dian'ieter. The next step in the process 01" making the tube consists in accurately spinning or otherwise forming the portions 2 and S to the exact contours desired, as slmwn in Fl pure 3, and in tapping the hole l oi the portion 2 and the hole 5 of the portion 3. If desired, those portions may be slightly bored out prior to tapping, although this operation n'iay be dispensed with under ordinary conditions. Preferably, however, the bottom ol the hole 4: is bevelled by a suitable boring tool to form a valve seat 6, as shown in Figures 3 and 4:. It is to be noted that this valve seat is adjacent the portion oining the parts 2 and 3 and consequently leaves a web or in- Serial No. 195,561.
wardly directed small flange at the valve seat between the holes l and 5. The tube is also turned down at its outer end to provide the bevelled face or end 7.
The generator tube and valve is completed by screwing the end tip 8 into the hole 5, and by screwing the valve stem 9 into the threaded hole 4.. It is to be noted that this valve stem provided with a shouldered portion 16 which cooperates with the seat 6. The
valve stem 9 is of sulliciently small diameter and isspaced from the inner walls of the tube 1, as shown in Figure at. The bevelled outer end 7 of the tube enters the tapered aperture of the fitting 11. The fitting 11 is, of course, provided with an end cap 12 and an inlet portion, 13 and. the valve stem 9 is provided with the manipulating hand wheel 14-. The valve stem 9, of course, may be provided with a needle point 1.5 adapted to project through the a ierture in the tip 8 in the usual manner.
It will be seen that a novel form of generator tube has been provided by this invention in which the entire tube is integral throughout and does not have any welded joints or any portions in its major extent formed of diilerent members.
It will be seen further that the generator tube very readily produced .in a cheap and rapid manner by the i'uethoiil described immediately above.
It will be seen further that the generator tube may be made from a very cheap stock, although it has the desirable characteristics cnun'icrated above.
Although the invention has been described 'in considerable detail, such description is intended as illustrative rather than limiting the invention may be variously embodied and as the scope of such invention is to be determined as claimed.
W e claim:
The method oil? maltin a generator tube for a gasoline stove, said method comprising cu t ting a tube into predetermined lengths, forming; one end of each tube length to provide a constricted portion with the interior of said tube from the restricted portion to one end formed with an unbroken Wall, forming a In testimony that we claim the foregoing more constricted portion extending outward- We have hereunto set our hands at l\'[ilwaukee, 1y from said first mentioned constricted porin the county of Milwaukee and State of \Vis- 10 tion to the other end, tapping each of said cousin.
5 constricted portions and leaving a web between said constricted portions, and forming ALEXANDER C. SLADKY. a Valve seat upon said web. JOSEPH SLADKY.
