SAFETY DEVICE FOR USE IN CONNECTION WITI-I REFRIGERATING-MACHINES.
Original application filed December 20, 1917, Serial N0.`208,145.
1919. Divided and this application filed August 3, 1918.
To all whom t may conce/11a:
Be it known that I, FRANK AINSWORTH WILLCOX, a subject of the King of Great Britain, residing at Dartford Ironworks, Dartford, in the county of Kent, England, have invented new and useful Improvements in Safety Devices for Use in Connection with Refrigerating-Machines, of which the following is a specification.
The present invention relates to safety devices for refrigerating machines and con stitutes a modified form of the apparatus shoivn in my Patent No. 1,297 ,97 5, of which the present application is a-division.
rThe accompanying drawing shows, dia grammatically, in elevation, my invention applied to a vapor compression refrigerating machine, the feature to which the present application is directed being the ejector associated with the safety device for removing the gases or vapors from the casing of the safety device to the delivery passage of the main compressor.
The safety device is shown as a spring valve A mounted in a surrounding casing B, at the top of which is a frangible dia phragm C, which breaks at predetermined pressure. The valve is in communication through pipe with the delivery or compression pipe 12 of the main compressor l) of the refrigerating machine, the remainder of which it is unnecessary to shoiv or de scribe.
Below the valve A a pipe d opens to the pipe and is thus in communication with the delivery pipe cl2 of the main compressor.
The pipe Z3 leads to an ejector G, into the` casing of which opens the pipe 712 leading if rom the casing B at a point above the valve Consequently the gases or vapors from the upper portion of the casing B are sucked into the injector and delivered thereby through the pipe c to the suction pipe d of the main compressor.
U pon excessive pressure in the casing B Specification of Letters Patent.
Patent No. 1,297,975, dated March 18,
Serial No. 248,225.
the valve A opens and the rush of gases ruptures the diaphragm C and escapes through the pipe c2 as explained in my patent aforesaid.
lVhat I claim is l. In connection with the safety devices of refrigerating machines, a casing constituting a vessel normally closed to the surrounding atmosphere and adapted to receive gases, or vapors, which may pass the safety i device, and means distinct from the main compressor of the machine for removing such gases, or vapors, from the said. casing, and comprising an injector connected With the interior of the casing and With a pipe leading from the delivery pipe of the main compressor of the rcfrigerating machine so that gases, or vapors, therefrom effect the Withdrawal of gases, or vapors, from the said casing.
2. In connection With the safety devices of refrigerating machines, a casing constituting a vessel normally closed to the surrounding atmosphere and adapted to receive gases, or vapors, which may pass the safety device, and means distinct from the main compressor of the machine for removing such gases, or vapors, from the said casing, and comprising an injector connected with the interior of the casing and With a pipe leading from the delivery pipe of the main compressor of the refrigerating machine so that gases, or vapors, therefrom effect the Withdrawal of gases, or vapors, from the said casing, the injector delivery being connected to the suction pipe of the main compressor.
ln testimony whereof' I have signed my name to this specification in the presence of tivo subscril'iing Witnesses.
