AUTOCLAVES, Horizontal Type, Continued. 



bronze, deeply concaved for strength. The two walls of the steam chamber are of Seamless 

 drawn copper and brass, the inner lined with pure block tin. Around the outer is a heavy 

 outside jacket to prevent radiation of heat and condensation of steam between the walls. The 

 instrument is mounted on a white enameled tubular steel stand. Complete with steam gen- 

 erator, water gage, safety valve, air valve, pressure gage for steam jacket, vacuum and pres- 

 sure gage for inner chamber, and necessary valves marked for use.

AUTOCLAVES, Foot Power, improved model with door controlled by a foot pedal, a patented 

 feature of this instrument. Foot pressure on the pedal closes the door and locks it in place 

 steam tight instantly, leaving both hands free and eliminating any possibility of scalding. The 

 steam generator is enclosed in the copper pedestal base, which is lined with asbestos, insulat- 

 ing and confining the heat, so that steam is generated with great rapidity. This design also 

 makes the autoclave more economical as well as more convenient to operate. All supply pipes 

 are brought up from the floor inside of the base, making a neat, compact installation. Con- 

 structed of cold rolled copper and bronze steam metal castings, nickel-plated throughout. 

 Complete with steam and return water supply, gas and safety valves, air cocks, steam, tem- 

 perature and water gages.

AUTOCLAVES, High Pressure, for sterilization or digestion under high steam pressure: widely 

 used for vulcanizing in dental laboratories. Consists of a wrought iron pot with heavy cast 

 iron cover accurately fitted to make a steam tight joint, and held in place by stud bolts pro- 

 jecting through the flange. Tested to stand a pressure of 60 atmospheres or about 900
