Description

i be observed that the spring in my invention ture falls below the desired limit, whereupon the current again passes between the cont-act points 84 and 35.
It is desirable that the current used in the vulcanizer be alternating, for the reason that with a direct current too great an` arc is formed between the contact points 34 and 35. It. is for this purpose that I use the condenser 36, which prevents the formation of the arc when a direct current is used.
It will be seen that the apparatus herein -disclosed is very economical and etlicient,
because the electric heater is entirely surrounded by water. LThe means for maintaining the 4temperature of the vulcanizer uniform is very accurate, since the slightest excess over the desired pressure 'breaks the electric circuit and prevents the further del velopmentof heat, until the temperature has again been reduced to the'predeterminedV degree. Moreover, the device is no topen to the objection heretofore foundfto exist in'` vulcanizers which depend upon a spring for transmitting pressure, as: such springs bef come imperfect in their operation by the re-v peated action of the Ysteam therein. It is to is not exposed to the action of the steam. At the same time it can -be easily adjusted to give accurate results.
By reason of a slightwelding that may occur between-the two points ofcontactit 50 times as great as that of the end of the rod. It is necessary that' its movement should belarge in order to obtain-accurate readings. Prior devices have been employed in which the movement of the pointer itself Vhas been utilized to break the electric circuit.
From what hasbeen already stated it will readily be seen that such devices are imperfect, because the amplitude of movement of the pointer must be very great, and therefore the force applied at the end of thef pointer must be proportionately small, and this force has not been found sufficient to be -depended upon to break the circuit at all times.
I"claim: A vulcanizer comprising a hollow casing,
an electric heater therein, a diaphragml adapted to receive on one side the pressure of steam generated by said-heater from water in said casing, a rod moved by the movement of the diaphragm under the inlfluence .of said pressure, a circuit breaker in the circuit ofthe electric heater, a movable p inter and means coperating vtherewith for il dicating the pressure, said rod being arranged by its movement due to the increase of steam pressure to operate said circuit breaker to break the circuit, and a positive train of mechanism connecting said rod with said pointer to positively move said pointer correspondingly with the movement of said rod, the movement of the end of the pointer produced by said rod being many times .greater than that of the movement `of the contact breaker produced thereby. In testimony whereof I have hereunto set my hand in the presence'of two subscribing witnesses.l y ANSEL C. HULBERT.
