Abstract
Abstract A thermostat assembly is disclosed which includes a bracket for attaching a thermostat to a tubular member, such as a pipe or tube, so that the thermostat may be reactive to the thermal condition of the tubular member. The bracket includes a longitudinal opening so that the bottom of the thermostat may directly contact the tubular member. The bracket also includes thermostat-retaining portions, each of which preferably includes an inwardly extending tab having a lance on the end to dig into the cement on the top of the thermostat. The bracket also includes clip portions which extend around and attach the bracket to the tubular member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
135 words
A thermostat assembly for attachment to a tubular member which comprises a thermostat having a heat-conductive bottom and containing thermal responsive means therein; and means for mounting the thermostat on a tubular member which comprises a base portion adjacent to the bottom of the thermostat and which is adapted to fit against and extend longitudinally along the tubular member and which has a longitudinal opening therein to permit the bottom of the thermostat to directly contact the tubular member, a pair of thermostat-retaining portions which extend from the base portion on either side of the thermostat and which have means for attaching to the thermostat, and a clip portion which extends from the base portion and which is adapted to extend around the tubular member to tightly attach the base portion to the tubular member.
Claim 2
Dependent Claim
135 words
A thermostat assembly for attachment to a tubular member which comprises a thermostat having a heat-conductive bottom and containing thermal responsive means therein; and means for mounting the thermostat on a tubular member which comprises a base portion adjacent to the bottom of the thermostat and which is adapted to fit against and extend longitudinally along the tubular member and which has a longitudinal opening therein to permit the bottom of the thermostat to directly contact the tubular member, a pair of thermostat-retaining portions which extend from the base portion on either side of the thermostat and which have means for attaching to the thermostat, and a clip portion which extends from the base portion and which is adapted to extend around the tubular member to tightly attach the base portion to the tubular member.
Claim 3
Dependent Claim
37 words
A thermostat assembly as set forth in claim 1, wherein the thermal responsive means comprises a snap disc located within the thermostat which is capable of two positions of stability in response to the thermal environment thereof.
Claim 4
Dependent Claim
22 words
A thermostat assembly as set forth in claim 2, wherein the snap disc is adjacent to the heat-conductive bottom of the thermostat.
Claim 5
Dependent Claim
29 words
A thermostat assembly as set forth in claim 1, wherein the means for attaching comprises a tab which extends from the thermostat-retaining portion and engages part of the thermostat.
Claim 6
Dependent Claim
38 words
A thermostat assembly as set forth in claim 4, wherein the thermostat is cup-shaped and has cement across the top of the cup, and the tab has a lance on its inwardly extending end which engages the cement.
Claim 7
Dependent Claim
22 words
A thermostat assembly as set forth in claim 5, wherein a pair of lances are formed on the end of the tab.
Claim 8
Dependent Claim
62 words
A thermostat assembly as set forth in claim 6, wherein each of the thermostat-retaining portions has a circular opening with a pair of cuts extending from the circular opening and forming a tab therebetween, and the pair of lances are formed on the end of the tab by the intersections of the rim of the circular opening and the pair of cuts.
Claim 9
Dependent Claim
150 words
A bracket for attaching a cup-shaped thermostat having a cement top and a heat-conductive bottom to a tubular member, which comprises a base portion which is adapted to be positioned adjacent to the bottom of the thermostat and to fit against and extend longitudinally along the tubular member, the base portion having a longitudinal opening therein to permit the bottom of the thermostat to directly contact the tubular member; a pair of thermostat-retaining portions which extend from the base portion and are adapted to be positioned on either side of the cup, each of the thermostat-retaining portions having an inwardly extending tab having a lance on the end thereof adapted to engage the cement on the top of the thermostat; and a clip portion which extends from the base portion and which is adapted to extend around the tubular member to tightly attach the base portion to the tubular member.
Claim 10
Dependent Claim
150 words
A bracket for attaching a cup-shaped thermostat having a cement top and a heat-conductive bottom to a tubular member, which comprises a base portion which is adapted to be positioned adjacent to the bottom of the thermostat and to fit against and extend longitudinally along the tubular member, the base portion having a longitudinal opening therein to permit the bottom of the thermostat to directly contact the tubular member; a pair of thermostat-retaining portions which extend from the base portion and are adapted to be positioned on either side of the cup, each of the thermostat-retaining portions having an inwardly extending tab having a lance on the end thereof adapted to engage the cement on the top of the thermostat; and a clip portion which extends from the base portion and which is adapted to extend around the tubular member to tightly attach the base portion to the tubular member.
Claim 11
Dependent Claim
21 words
A bracket as set forth in claim 8, wherein a pair of lances are formed on the end of the tab.
Claim 12
Dependent Claim
61 words
A bracket as set forth in claim 9, wherein each of the thermostat-retaining portions has a circular opening with a pair of cuts extending from the circular opening and forming the tab therebetween, and the pair of lances are formed on the end of the tab by the intersections of the rim of the circular opening and the pair of cuts.
