VULCANIZER.
Speciication of Letters Patent.
Patented Apr. 6, 1920.
Application filed May 12, 1919. Serial No. 296,479.
To all whom it may concern.'
Be it known that I, ARTHUR A. DonsEY, a citizen of the United States, residing at Lawrence, in the county 'ofy Douglas and State of Kansas, have invented certain new and useful Improvements in Vulcanizers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and vuse the. same, reference being had to the accompanying drawings, and to the letters and figures 'of reference marked thereon, which form a part of this specification.
This invention relates to vulcanizers. The primary object of the invention is to provideA a vulcanizer adapted for treating the casings or shoes of pneumatic tires capable of use in connection with motor vehicles.
Another object of the invention isto provide a vulcanizer which will be simple 4in construction, durable, and efficient in operation.
Another object of the invention is to provide a machine so constructed'that a uniform heat may be'maint-ained throughout the periphery of the tire, means being also providedwhereby the heat to the upper half of a tire may be shut off and Iv have also provided means for utilizing interchangeable bead molds so thatvarious size tires may be treated inthe same apparatus.
Other objects and advantages of the invention will be referred to hereinafter, it
being understood that changes in form, proportion and minor details of construction.
may be resorted to' without departing from the vspirit of the invention or sacrificing any of its advantages. l
In the drawings,
Figure I is a perspective view of la machine 'constructed in accordance with my invention.
Fig. II is a bead molds.
Fig. III is a perspective View of a sectional tread mold.
F ig. IV is a, vertical longitudinal sectional view through the device.
Fig. V is an enlarged sectional view ot jointure of the two halves, and
Fig. VI is a sectional View o'f a slightly modified form of the device.
Referring now to the drawingsby nuperspective view of a pair of the -merals of reference two halves are brought together, as shown in Fig. I, a circular mold-receivmg seat 11 is provided surrounded by a circumfer-4 ential Huid-directing heat chamber 12 com muni ating with a water chamber 13 in the base 14 of the member 6. Steam is generated in the base 1l and is adapted to pass. from the section 6 to the section 5 through the ports or tubes 15, the ends ot' the sec tions being otherwise closed and in the -ports 15 are valves 16whereby said ports may be closed when the top member is removed. The ports 15 extend beyond the ends of the member (3 in the form of dowels, 80
as best seen in Fig. V, so that when the two sections are brought together and the valves 16 moved to opening position, the steam may fill the entire circumferential chamber 12. The seat'll is in the form of a central'circumterential groove adapted to receive a tread mold 17 andthe bea-d molds18 and 19, the former preferably consisting of two halves and the latter consisting of circumferential rings yhaving inwardly projecting flanges 20and 21, the alining edges 22 and 23 of which abut, as best seen in Fig. I V, and these mold members are secured in place by the adjusting screws 24 in the bars 25 carried by the screw members 26 and v27 and 95 bead tanks are then applied to the tire'anlv the assembled parts are placed in the'lower section 6, the upper section is then put in4 place and the two* halves are fastened together by the bolts 7 and 8. The bars 25 arethen properly positioned and the screws 21 are then adjusted to clamp all of the parts together. The valves 16 may then be opened to admit steam to the upper half 5 and the tire -may remain in the machine a sufficient length of time to complete the desired operation.
When it is desired to remove the tire, the valves 16 will first be shut oii', the upper half of the casing 5 removed, the clamps released and the tire, together with the molds, may be taken out without y releasing the steam pressure .because this cannot escape from the casing (3 'onfaccount of the valves 1G. l/Vhen the steam pressure is too high, however, this may be relieved by opening the pet cock 28 and observing the pressure gage 29. It is to be understood, ofcourse, vthat different size molds may be employed for different size tires; therefore, the device is capable of use in connection with tires of the same diameters butdiferent sizes of tread.
It will be observed that' when the tire is in place, the heat from the steam will be com- .municated direct to the rubber through the wall 30 `and the molds 17, 18 and 19, and since the steam will be directed at a uniform pressure about` the entire periphery of the tire casing or shoe, a uniform heat will be applied.
In Fig. VI have shown a slightly modi-v fied form of the device in which conl'munication may be had between the upper and lower halves through th medium of a flexible connection or hose 15. This will enable the upper half to be removed Afrom the lowerV half without breaking the connection so that steam pressure may be maintained in both halves. By reference to Fig. III it will be observed that the halves-of the tread molds may be connected together by latches 31 er1- gaging sockets 32, it being understood that thetreadmolds may be constructed of varif ous sizes to accommodate different tires.
By reference to Fig. I it will be apparent that a pet cock 33 may be installed in the upper half of the mold.
What I claim and desire to secure by Letters-'Patent is:
1.- A' vulcanizer comprisinga circular casing*y consisting of an upper semi-circular member and a lower semi-circular member, the ends of the members having communication through hollow dowels carried by one vsection and passing into the other,'valves for -3. A. vulcanlzer comprlsmg a'elrcular casing *consisting of an upper semi-circular member and a lower semi-circular member, the ends of the mem-bershavmg commumca- `tionthrough hollow dowels carried by one' section and passing into the other, valves for cutting off communication between the sections, removable circumferential tread and bead molds receivable within the easing, and
'means for connecting the two members.
In testimony whereof I aiiix my signature.
ARTHUR A. DORSEY.
