The invention relates to cylinders for compressed gasesor gaseous fluids and more particularly to cylinders constructed of seamle s drawn metal, that is to say, cylinders formed from, a billet by piercing, extrusion and drawing. According to that method, the bottom of the cylinder lsclosed under the steps of piercin and extrusion, and after the final drawing t e top is formed by forging with necking hammers or by spinning, which closing operation adds materially to the cost of 3 tion of packing andthe manufacturing. Moreover, a cylinder so formed is impractical for certain uses. For example in the case of acetylene where a solid packing is used inside the cylinder, the cylinder should be open to rece ve the packin and then closed.
. ence, the objects of my invention are to adapt seamless drawn cylinders for certain us'esfor which heretofore they were impracticable and generally to lessen the cost of manufacture of: such cylinders.
The nature of the invention consists in providing a seamless drawn cylinder. having a die formed top or valve-receiving portion,
the other end being full '0 en for the receplil i e and being-ultimately closed in any approved manner.
The invention in its preferred form is illustrated in the annexed drawing, wherein Figure 1 is a longitudinal sectional view of a seamless drawn cylinder whereof the top I v is formed in the initial cupping operation.
Fig. '2 is a similar view showing the completion-of the next step of and ta usual valve.
Fig. 3 shows the bottom closed as, for example, from the rwult of spinnm g Fig.4 shows a cylinder with abotton welded to place.
In the practice of der 5, under the die forming operation of pierc' and extrudmg' or cuppi is provided with a solid or in id to p It is a merit of the invention that the top 6 is formed with aninwardly axial projection or boss 7 to insure adequate seat depth of the usual valve when the top is dnlledandtappedasat8.
1980. Serial No. 447,318.
the open or ultimate bottom at any rate in the'case of packed acetylene or with liquefied petroleum gas, is shown in Fig. 4 in which 10 represents a dished head that is welded to place.
Having described the invention, what is claimed is: I
The method of forming seamless drawn metal 0' linders, which consists in forming from a illet by piercing and drawing 2. cylinder having a closed head portion characterized by its thickness with relation to the side wall section and by an inwardly directed axial boss, the other end of the cylinder being open its .full diameter,boringand tapping said closed head portion, including its co-extensive boss, for the reception of a valve, and ultimately closing the open end of the cylinder. r
