Abstract
Abstract A ceiling air terminal serving as part of an air-conditioning system for a building adapted to discharge conditioned air into an area to be treated. The terminal is provided with a bleed-type thermostat employing a perforated bimetallic element movable in response to temperature variations in the air passing through the perforations from the area served by the air terminal to regulate the quantity of air bled from the thermostat and thereby control the quantity of conditioned air discharged from the terminal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
127 words
A bleed-type thermostat comprising: a housing; means forming a bleed port associated with said housing; blockage means operably associated with said bleed port for regulating the flow of air through said port; adjustable support means mounted on said housing; a U-shaped perforated bimetallic element, one end of said perforated bimetallic element being affixed to said adjustable support means for adjusting the location of said bimetallic element relative to said housing; means associated with the other end of said bimetallic element for moving said blockage means in response to movement of said other end of said bimetallic element, passage of ambient air through the perforations in said bimetallic element causing movement thereof in response to ambient temperature variations to regulate the flow of air through said bleed port.
Claim 2
Dependent Claim
127 words
A bleed-type thermostat comprising: a housing; means forming a bleed port associated with said housing; blockage means operably associated with said bleed port for regulating the flow of air through said port; adjustable support means mounted on said housing; a U-shaped perforated bimetallic element, one end of said perforated bimetallic element being affixed to said adjustable support means for adjusting the location of said bimetallic element relative to said housing; means associated with the other end of said bimetallic element for moving said blockage means in response to movement of said other end of said bimetallic element, passage of ambient air through the perforations in said bimetallic element causing movement thereof in response to ambient temperature variations to regulate the flow of air through said bleed port.
Claim 3
Dependent Claim
74 words
A bleed-type thermostat according to claim 1 wherein said blockage means comprises a bleed plate overlying said bleed port, movement of said bleed plate relative to said bleed port regulating the flow of air through said port; and said means associated with said blockage means including motion amplifying means disposed between the other end of said bimetallic element and said bleed plate to amplify movement of said bimetallic element for positioning said bleed plate.
Claim 4
Dependent Claim
61 words
A bleed-type thermostat according to claim 2 wherein said bimetallic element is adapted for movement in a plane perpendicular to the movement of said bleed plate, said motion amplifying means including a pivoted lever having unequal length arms, the shorter arm being adapted for contact with said bimetallic element and the longer arm being adapted for contact with said bleed block.
Claim 5
Dependent Claim
28 words
A bleed-type thermostat according to claim 3 further including biasing means associated with said bleed plate to bias said bleed plate toward the longer arm of said lever.
