VI'TUS SGHWANINGER, OF OGGER SIIEIM, NEAR MANNHEIM, GERMANY.
PROCESS FOR UNIFORMLY COVERING WITH LEAD HOLLOW BODIES.
Specification of Letters Patent.
Patented March 9, 1909.
Applicator: filed December 13, 1907. Serial No. 406,862.
vpi es, vessels, boilers and the like.
he rocess consists in first providing the interna. surface of the hollow body, the interior of which is to be covered with lead, with a coating metal, such as tin, zinc and the like in the well-known manner, in then introducing a leaden pipe into the hollow body in rotating thelatter with the lead pipe and heating themwhile they are being rotated until the lead begins to melt and is pressed against the interior surface of the hollow body by the centrifugal-force.
In order that the invention may be clearly understood, reference is made to the accompanying drawing, in which one form of the apparatus for carrying the same into effect is represented by way of example in vertical section.
As canbe seen from the accompanying drawing the hollow body 1 for this purpose maybe mounted with one end on the chucklate 2 of the lathe. The other end of the ollow body is inserted in a bearin 10, so that when the chuckplate is rotated t 1e hollow body can rotate with the same in the bearing 10;
3 is th lead pi e, which is introduced into the hollow body efore the chuck late 2 be+ gins to rotate together with the ho] .ow body 1'.
Underneath the hollow body a gas-pipe 6 is fixed on the frame of the lathe by means of pipe hangers 8 or in other suitable manner and is provided with perforations 7 for the emission of the gas. The gas pipe is com nected with a gas supply 1pc 9. As soon as the chuck-plate together with the hollow body beigns to rotate gas is admitted to the pipe 6, and the gas passing through the erforations of the gasi e is lighted. he hollow body is heater y the gas burners until the lead-pipe inside the hollow body begins to melt and is ressed against the interior surface of the ollow body in conseuence of the centrifugal force. t at the li uid metal may not flow out of the hollow b0 y the latter is provided at both ends with flanges 4, 5 projecting inward. A material advantage of the new process resides in the liquid lead being pressed outward against the interior surface of the hollow body not by means of internal excess pressure, as inthe case of some of the methods hitherto employed, but by means of centrifugal-force due to'its great specific weight; consequently the impurities present in thelead, as well as other parts of less specific weight, lie on or near the interior surface, so that the lead exhibits roughness on its interior surface, which roughness can be moved by turning, boring and the like. The lead coat ng then remaining in the hollow body is perfectly free from im urities and is conse uently capable of resisting the action of aci s, acid containingvapors etc, to a far greater extent than a coating of lead mixed with impurities.
I claim A process for homogeneously internally coating with lead hollow bodies provided on their interior surfaces with a preliminary coating of metal consisting in rotating a leaden pipe, introduced into the hollow body, with the latter, and in heating the hollow body while it is being rotated until the lead beglnsto melt and is pressed against the interior surface of the hollow body by the centrifugal-force' In order The fore oing specification si ned at Mannheim, ermany this twentyfth day of November, 1907.

In presence of two witnesses: TERESA CATHERANI, Jos. H. Laura.
