Patented Nov. 21, 1922.
Patented Nov. 21, 12223 UNHTELDD STATES FATENT FRANK E. HOLOOMB, OF AKRON, OHIO, ASSIGNOB. OF ONE-HALF TO THE WILLIAMS FOUNDRY AND IMACHINE 00., OF AKRON, OHIO, A CORPORATION OF OHIO.
PRESSED-STEEL VULCANIZEB.
Application filed'october 15, 1920. Serial No. dl'flllfi.
To all whom it may concern:
Be it known that I, FRANK l). lioLooMn, a citizen of the United States, and a resident of Akron, in the county of Summit and State of Ohio, have invented. certain new and useful Improvements in Pressed-Steel Vulcanizers, of which the following is a specification.
My present invention relates to improvements in vulcanizers of the type used for repairing the outer casings of double tube pneumatic tires. Heretofore such vulcanizers have usually been made from cast metal.
Such cast metal vulcanizers are extremely heavy and are furthermore expensive, due to the amount of accurate machine work necessary to properly finish the castings.
The present invention aims to provide a vulcanizer which will be much lighter than the cast form, and which may be much more economically and expeditiously manufactured.
With these and other objects in view the invention includes the novel construction and arrangement hereinafter described and particularly defined by the appended claim.
An embodiment of my invention is illustrated in the accompanying drawings, in which:
Fig. 3 is a section on line 3-3 of Fig. 1 looking in the direction of the arrow.
Referring by reference characters to this drawing, the vulcanizer is shown as comprising mainly the inner and outer sections 1 and 2 which are curved transversely into approximately trough shape, and are also curved longitudinally.
The inner section has its interior channel shaped to conform to the section of the size tire for which it is designed, and the walls of the two sections are preferably concentric and spaced apart to provide a steam chamber. These sections are made of sheet metal such as steel, which is stamped or pressed into the required shape.
Means are provided for closing the space between the edges of the plates or sections to form a closed steam chamber. In. my preferred embodiment the lengthwise edges of one of the sections (say, the inner) are pro vided with angularly turned portions 1 which are united with the edges of the other section, preferably by welding.
The ends of the steam space are preferably closed by substantially horse-shoe or U-shaped plates 3 which may also be welded to the edges of the sections 1 and 2.
Preferably the edges to be welded are beveled as shown to facilitate the welding operation.
A support for the vulcanizer is indicated at l: which has a central curved portion at welded or otherwise suitably secured to the outer section, and depending side flanges a forming legs or supports. The side fianges or supports a are turned outwardly and preferably provided with bolt holes 6 by which the vulcanizer may be bolted to a suitable base or support.
Openings for steam inlet pipes are provided as indicated, for example, at 2", and an opening for a drain pipe for water of condensation as indicated at 2.
Strips of steel indicated at 5 are welded to the outer upper edges of the vulcanizer to serve for connection of the arms of the pressure means used in connection with devices of this character such as shown for example in the application of John Flynn, filed July 19th, 1920, Serial No. 397,348.
What I claim is:
A tire vulcanizer comprising inner and outer longitudinally and transversely curved members of sheet metal, one of said members having angularly turned edges welded to the edges of the other member, and a supporting member having a portion secured to the outer surface of the outer member.
In testimony whereof I affix my signature.
FRANK E. HOLCOMB.
