DRY-HEAT VULCANIZER.

Specification of Letters Patent.

Patented Feb. 13, 1912.

To all whom it may concern:

Be it known that I, HARRISON M. Dn'rmcn, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Ini rovements in Dry-Heat Vulcanizers, of w ich the following is a speci fication.

My invention relates to improvements n vulcanizers generally,-but, more directly to what I term a-dry-heat vulcanizer:and while the device is designed for vulcanizing pneumatic tires of various kinds, it is more especially intended and adapted for repairing the pneumatic-tires of automobile wheels.

Some of the principal objects of this invention, consist in producing a vulcanizer as above referred to, that will more effectively vulcanize or close an opening,eaused by friction or puncture ;.or in placing a patch over a torn place in any rubber body. Also, in so constructin said device as to dispense with the objectionable water system, by providing in lieu thereof my dry heat system, thereby treating a uniform heatin power giving better results generally. urther objects being to provide said device of simple construction; composed of few parts which will seldom if ever need any repairs; and one which can be manufactured at small cost and therefore is quite inexpensive.

- My invention consists essentially, referring briefly and in general terms to the device, of the very peculiar construction, arrangement and combination of the various mechanical parts orelements and the minor details thereof, as will be hereinafter fully described and set forth in the subjoined claims all in accordance with the statutes in such cases-made and provided therefor.

Referring to the accolnpanyin drawings constit-utin a formal part of. t IlS s ecification,-an illustrating one form 0 con" structionfor carrying out the objects and principles of my invention, and wherein the same reference letters are utilized to indicats or point out the same parts wherever occurring throughout the several'viewsz- Figure 1 is a side view of my vulcanizer, showing the position the parts assume when repairing the inner tube of a pneumatic-tire or similar body that has to be supported.

ig}, is a front view of same partly in section, with front portion of gage; face-plate; supporting strap and burner-stand removed. Fig. 3, is an inner view of the face-plate. Fig. 4,is a cross sectional view-on line ma; of Fig. 1. Fig. .5, is a perspective view of the supporting plate. Fig. 6, is a perspectivevrew of the supporting strap. F i 7,

is a perspective view showing the app ication of the device when vulcanizing a body that has to be supported ;such as an inner tube of a pneumatic lire; and Fig. 8, is a perspective view showing the application of the device when vulcanizing or patching the outer surface of a body that does not have to be supported;-sucli as an outer casing or tube of a pneumatic tire of an automobile wheel.

In describing my said-invention specifically, and referring in detail to the various parts or features of construction which in combination make up my dry heat vulcanizer, as pointed 'put in the drawings .by means of the reference characters as aforesaid :'a refers to the burner-stand provided with feet b, which may be screwed or otherwise securoly attached to a work-bench or table, as more particularly shown in Figs. 1 and 7 :or any suitable means for receiving and supporting burner A,whe n any unsupported article or body, such as an inner to material, as shown in Fig. 2; said wool having poured thereon, a suflicient quantity of alcohol until it is absorbed by and saturates same; and over said wool is placed a wire screen a, removably held therein by means of a retaining-spring d. Extending around said burner near its top are arranged draft openings e, by which the flamecreated by the alcohol when ignited,-can be controlled by means of a regulating-band f, provided with a handle F, which can be moved over, or away from said draft-openi s by reason of the frictional contact of sai band with said burner. I

Removably connected. to the burner in which it telescopes a short distance, form'- ing a slip-joint connection near its top; and in which it rests and is held by reason of its frictional contact therewith, is the neck 9 a section of which extends from the body G 1.

the other section extending from face-plate h; said neck forming an. open communication with the dry heating chamber or comartment H, when said face-plate is secured in operative position-see Figs. 1 and 4.

Body G, is preferably formedwith a concaved-face '5, having a smooth surface, thus adapting it to more readily receive and bear against pneumatic tires and other round or curved bodies, while heating, when vulcanizing'in" of repairing same. Said body is provided with recesses in, forming outlet or escape ports when face-plate h, is in position; thus allowing for the eseape of all dead gas from said heating chamber. Projecting from said bod are the ears or extensions J, each of w ich is provided with a screw-eye at l for attaching the face- 1 being lighted' as heretofore fully described when the strai ht siphon Nis then placed in said boilen'w 'ere t is held in asuspended position" therein by means of its screwthreaded neck 'e'ngagin'g'the internal screwthreads of, moutheplece M--'asfully shown in-Fig'. 2. v I

heating chamber fl; reseites sufiicient dry heat fromcburnr' ikj-fia's previously referred to; boiler twill-* also quickly become heated, by reason of the intense dry heat in saidphamber, when the. water In said bOllEIAlS it boilsiwill v nerate suflicient steam, the pressure of which will force some of said water up siphon Nand into hollow gage-spring n of age when the pressure of said water wi l actuate said gage spring and the sensitive mechanism at p' to which it is connectedsee" Fig. 2

which will in turn affect the indicating hands and indicate on the gage dial the temperature or. amount of heat, in the ordinary and well known manner, so the workman will know how to regulate said heat to properly vulcanize. Straight siphon N EiS connectedto gageO so asto form a continuo'us andropentaonnnunication with,

n, as any and clearly shown inF1g. 2.

, Said-gage being of the usual and wellknown form of construction and'no' art of this invention it is not necessary to here further illustrated or described, as any form or style ot'igage of suitable construction adapted for the purpose intended can be employed.

Fa eplate k removably connected to body G, preferably by means of screws-as shown at Z b dotted lines in Fig. 4, and when screwe in position forms a tight cover for said heating chamber as shown; and is provided with a handle l-which for the purposes of storage and transportation of the device,is preferably connected thereto by means of a screw-threaded shank g-see F igs. 1 and 4;by which the device can be li ted and mover. Said face-plate is further rovided near the top on its inside surface, with a flame or fire shield 'r in form .of. a flange projecting at right-angles therefrom and coming just below the outlet or esca e ports formed by recesses la, and exten ing into said heatin ciently to prevent any so den draft of air passing through said outlet ports into and down said heatin chamber and affecting the flame; thus a ways keeping the flame from the burner uniform.

As a means for holding and sup orting my dry-heat vulcanizer, and binding or pressing the concaved face vof body G against the part to be repaired, when vulcanizing or patching a rather large article or body that does not have to be supported by the device,such as the outer caslngof a pneumatic-tire on an automobile wheel, as shown in Fig, 8 ,I employ the supporting strap R, havin f1: connecti-n buckle s for adjusting it to arge or smali si'red as fully and clearly illustrated in Fig. 6. aid strap being provided with the screw-threaded arms 6, one of which passes through and rests inv eye m of one of the body ears J, while the other-arm t tests in slot m of other body ear J: said screwthreaded arms each carrying a-thumb-screw u for tightening and adjusting the vulcanizerto the part to be repaired; see Fig. 8.

When repairin an article that has to be eupgorted and w en burner stand a is utias heretofore described; I employ asnp orting or counter late- T,- provided wit 1- ears or extensions each having a slot 2: adapted to fit over and rest on arms t of said supporting strap'; thus supplort-ing, plate T, the converted-face w of who bear- Ill against and forcing the portion to be .vu canized against concaved face i of body G :see Figs. 1, 4 and 7,and by means of buckles s and thumb screws u, said stra and the supportin late can readily be a justed as requirei A very important feature of my invention consists in my dry heating system, wherein I provide my vulcanizer with the dry heat chamber H, havin the boiler -L located therein, whereby su cient steam is generated to affect and control the dry heat in said chamber, thus securing a uniform heating power which is not otherwise secured. Another very important feature of my mventiou consists in providing my vulcamzer bodies as de- 80 chamber sufli with the straight siphon 3T, seated in and o crating in combination with the boiler, w ereby the steam forcing the water through said siphon directl into gage prin n, will cause the hands 0 the gage to in icate on its dial the temperature or degree of heat; and by this system of water, instead of steam pressure-as heretofore,-I do not weaken, and shorten the life of the gage mechanism,but prolong the life ofs same. "Also another important feature of m invention, consists in providing burner with the draft opening e and regulating-band whereby the ame can always be propery regulated and controlled.

Having now described my (1 -heat vulth a hollow gage-spring within said.
