,Application filed July 25, 1.912. Serial No. 711,461. 'f

B e it knownthat I, FREDERICK MARTIN, a 'citizen of the United States, residinga-t Pomona, in the county ,of Los Angeles and -State'of California, 'have invented a new ,f 'praofticalvulcanizen including a device that will Aautomatically open and close the elec-` tric circuit, in order to automatically regulate the necessary amount of heat.

' The drawing discloses certain features, -butin practical fields these features may require alterations, to which the patentee entitled, provided the alterationsoare comprehended within 'the scope of what is claimed.'

The invention comprises furtherfeatures and combination of pa1ts,',as hereinafter set forth, shown in the drawings .and claimed.

In the drawings Figure 1 is a front view of the improved vulcanizer constructed in accordance with the invention. Fig. 2 is -a side elevation of the same. Fig; 3 is a View in rear elevation. F ig. 4 is arplan view. Fig.- 5 is a bottom plan view showing the construction of the heater, Fig. vG is -a Sectional view on line 6--6 of Fig. `Referring to the drawings 1 designates the base of the vulcanizer, which is constructed with` a flange 2, and is provided with a plurality of resistance plates 4, which together with the base are to become electrically heated, in order to convert the water in the pipe 5 into steam. Projecting from one ofthe iianges of the base is anotfset portionor extension 3, from which a bracket .arm 6 rises, This bracket arm G is secured to the extension 3, by `the casting 7, which is riveted or otherwise secured at 8 to the extension. The bracket armA `is constructed with anoverhanging portion 9, in which a rod l() is vertically movable. r This rod 10 is

terminals

26 and 27.

threaded in the overhanging portion 9,-and 1s provided with a. winged head 11, whcrebv 'the rod 10 may be adjusted. To the lower end ofthe rod a revolving plate 12.is swiveled` in any suitable manner as shown at 13,

.the .detailed structure of which, however, is

not particularly shown.. An inner tube of a rubber tire is adapted 4to be held. between.

plate and vthe base of the vul- .the revolving camzer, In order to be vulcanized.

The end 14 of the tube 5 is secured'inanyl A suitable manner at 15 in the iange of the base `1, and'threaded in the end portion 14 1s a short pipe 16, to which the elbow, 17 is threaded., a pipe 18 is threaded into the elbow 17 and terminates in a member 19 to which a. hollow tube 2O connects. This tube 20 is curved as shown in Fig. 1 and terminates in a plate 21 provided with a platinum contact 22. Thecontact 22 cooperates with a like contact 28 of the' plate 24, which in turn is secured at 25 tothe memberv 19.- The base 1 is provided-with neets the terminal 2T and the Contact 2" while a wire 29-from any suitable source of current supply (not shin-vn) is connected to the terminal 26. A wire '30 also leads from the currentfsupply and connects to the contact '23.

Water from any suitable source (not shown) may be introduced into the pipe 5. Where it i-s converted into steam,'and since the resistance plates are constructed of iron,

they become highly heated.A From this heat the water in the tube is converted into steam,and since the tube 20 is connected to the tube 5, through the member 19, the pipe 18, the elbow l17 andthe pipe 1.6, the said tube 20 expands under-'the steam pressure, thereby separating the

contacts

22 and 23, and since such contacts are in-cir.- cuit with the Current supply', the circuit is made' andsbroken, thereby properly regu? lating the amount of heat necessary in the resistance plates for vulcanizing rubber tires and the like. In this manner the heat remains substantially,constant andiuniform.

vAs' the heat slightly' decreases, the contacts 22`an'd 23 come together and again the circuit is closed, vthereby heating resistance plates. a

From t-he foregoingit is to be observed that there has been devised `anovel an'dl A wire or lead conbase provided with an Otel-hanging nieniber,

of an adjustable device including a: revolving plate between which' and the base anautoinobi'le tire is adapted to be clamped for vulcanizing, a series of 'resistance plates adapted to be heated from any suitable Source of 'current supply and arranged in said base,.a pipe designed to contain Water to be heated by the resistance plates and fixed in said casing and provided with an elbow at one end, a member adjustably connected, to said elbow and provided with an eXpa-nSible. tube terminating in a plate prol -ber and having a point constituting a stationary c0ntact,.said stationary .and 1novable. contacts being in circuit With the re-v sistance plates, said resistance plates adapted to heat the base and the pipe, and as the heat lvaries the tube correspondingly exf panels. oncontaets so as to open and close the circuit.
