Abstract
Abstract The gauge involves the use of two separate pressure-measuring members both of which are responsive to a single source of actuating pressure. One of said members actuates the pointer of an indicator whereas the other member simultaneously actuates a control member which in turn controls remotely located alarm, signal or other mechanisms. No change is required in conventional mounting of the gauge, using a single connection to a pressure source.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
137 words
A combination pressure-responsive indicating and actuating device comprising a housing, a hollow socket member in said housing and including a single inlet fitting extending through a wall of said housing for attaching said device to a source of fluid pressure media, a first pressure-measuring member connected directly to said socket member in direct fluid communication therewith and including means for indicating the pressure being measured, a control member, a second pressure-measuring member in fluid communication with said socket member, said second pressure-measuring member comprising an axially expansible bellows member in fluid communication at one end with said socket member, actuating means in cooperative association with the other end of said bellows member and movable by said bellows member for actuating said control member, said socket member distributing fluid pressure media to both said members independently and simultaneously.
Claim 2
Dependent Claim
137 words
A combination pressure-responsive indicating and actuating device comprising a housing, a hollow socket member in said housing and including a single inlet fitting extending through a wall of said housing for attaching said device to a source of fluid pressure media, a first pressure-measuring member connected directly to said socket member in direct fluid communication therewith and including means for indicating the pressure being measured, a control member, a second pressure-measuring member in fluid communication with said socket member, said second pressure-measuring member comprising an axially expansible bellows member in fluid communication at one end with said socket member, actuating means in cooperative association with the other end of said bellows member and movable by said bellows member for actuating said control member, said socket member distributing fluid pressure media to both said members independently and simultaneously.
Claim 3
Dependent Claim
25 words
The gauge as defined by claim 1, wherein said actuating means comprises a pintle engaged in axial alignment with said other end of said bellows.
Claim 4
Dependent Claim
16 words
A device as called for in claim 1, wherein the control member comprises an electric switch.
Claim 5
Dependent Claim
19 words
A device as called for in claim 1, wherein the control member comprises a valving member for fluid media.
Claim 6
Dependent Claim
29 words
A device as called for in claim 1, wherein means are included for selectively adjusting the pressure at which the control member is actuated by the second pressure-measuring member.
Claim 7
Dependent Claim
18 words
A device as called for in claim 1, wherein the first pressure-measuring member comprises a bourdon tube gauge.
Claim 8
Dependent Claim
36 words
The gauge as defined by claim 6, wherein the control unit includes an electric switch having contact means shiftable between open and closed circuit positions incident to the presence of predetermined pressure in said bellows member.
Claim 9
Dependent Claim
25 words
The gauge as defined by claim 7, wherein the combination includes means for indexing the operation of the control unit to readings of the indicator.
Claim 10
Dependent Claim
40 words
The combination as defined by claim 8, wherein is included a calibrated dial in position to be swept by the indicator, and protective cover means on the gauge enclosing the pressure-measuring member and control unit and the indexing means aforesaid.
Claim 11
Dependent Claim
35 words
The combination as defined by claim 9, wherein the hollow socket member inlet serves to supply fluid media to both the bourdon tube and the measuring member through the chamber of the socket member aforesaid.
Claim 12
Dependent Claim
49 words
A device as called for in claim 1, wherein the first pressure-measuring member comprises a conventional bourdon tube indicator gauge including a housing and a socket having a single inlet connection, and wherein the second pressure-measuring member and control member are mounted to but externally of the gauge housing.
Claim 13
Dependent Claim
29 words
A device as called for in claim 11, wherein the second pressure-measuring member and control member are encLosed within a housing secured to and carried by the gauge housing.
Claim 14
Dependent Claim
38 words
The gauge as defined by claim 1, wherein a tube is connected between said hollow socket member and said bellows member for conveying fluid media directly between said bellows member and the chamber of said hollow socket member.
