Description
Patented Jan. 4, 1944 SYSTEM Joseph L. Bradfleld, Seattle, Wasln, asslgnor of twenty-five per cent to Paul Wayne Bradfleld,
Tacoma, Wash.
Application April 18, 1941, Serial No. 388,71914 3 Claims. (01. 285106) This invention relates to improvements in a connection for heat exchange systems and one that is particularly useful in radiant heat systems.
It is well known in the art of heating and cooling buildings that wall, ceiling or floor areas of such buildings may be provided with pipe or tubes that receive a heating or cooling fluid and conducted throughout the areas according to a predetermined arrangement to either radiate or absorb heat depending on the temperature of the' fluid.
This invention has for its object the provision of novel and useful means for installing the tubing or piping in place in the wall, ceiling, or floor or a building into'which the system is to be inan improved control mechanism for regulating the flow and temperature of the fluid throughout the system. a
A further object of my invention relates to a method of preserving the integrity of the surface of the plaster which covers the secondary tubing and the supply and return lines of tubing by preventing any disruptive strains within the plaster due to the alternate expansion and contraction of the tubing.
Other objects and advantages of the invention will be apparent during the course of the following descriptionwherein I have illustrated a preferred form of my invention.
Figure l is a bracketed view of the tubular elements that are coupled together to form an intersection between a supply or return tube and a secondary distribution tube,
Figure 2 is a perspective view of an assembly of supply and return tubes with the secondary distribution tubes associated therewith,
Figure 3 is a plan view of a portion of a ceiling having my system installed thereon and indicating the manner in which it is imbedded in the covering plaster,
Figure 4 is a sectional view taken on lines 44 of Figure 3, and
Figure 5 is a sectional view taken of Figure 3.
.In heating an area in a house according to my on line 5-5 invention I propose to provide the heating element or tubing in the ceiling. Under such circumstances a feeder or supply tube I05 is run across an area. In the approximate center thereof and parallel thereto is provided the return tube- I05--both of these are of about the same capacity. These are connected respectively to the supply pipe and return pipe of a heating system.
At spaced intervals along the tubes I05 and I08 a notch I0! is formed and a notched saddle fitting I08 is soldered or brazed thereto in the manner clearly shown in Figure 2 so that the notches I01 and the notch I09 in the fitting I08 are coincident with each other. The fluid which may flow through the pipe I05 or I06 may pass into or out of the secondary loops H0 and III. In a regular installation a secondary loop at IIO, for example, has an and inserted into the saddle I08 on the pipe I05 and its other end is inserted into a saddle I08a on the pipe I06. Similarly a loop I is associated with the saddles I08 and MM on the opposite side thereof. It will be seen that hot water flowing through the pipe I05 will flow in both directions from the saddle I08 out around the loops H0 and III and then converge again in the saddle I080 to flow back through the tubing I05 to the return header and the heating plant. I
To provide a recessed support for the supply and return saddle fitting tubes I05 and I06 spacer blocks II2 are fastened to the opposite sides of a ceiling joist I I3 and positioned as shoufn or a pair of joists in any convenient location in the room. Nailing strips II4 are positioned on the spacer blocks I I2 with their lower edge in line with the lower edge of the joist I I3. The plaster base or lath H5 is nailed to the strips III. In this manner .a cavity is formed along each side of a joist or along one side of each of a pair of joists in'each room to receive the supply and .return tubes, I05 and I06 leaving only the saddle fitting I00 and I 08a protruding below the face of the plaster base or lath. The several loops H0 and I II are inserted in saddle fittings I08 and IBM and fastened to the lower face of the plaster base or lath. A wire mesh H6 is then stretched below the loops and is anchored by means of nails Ill nailed through to the joist to form a supporting member for the loops H0 and I I I and to act as a plaster reinforcement.
Plaster is troweled over the whole structure. As .the plaster hardens after a predetermined period of time has elapsed, it is conventional practice to heat the fluid in the system and perit it to flow throughout the distribution system ;comprising the feed and return -pipes l05. and H06 and the distribution loop'sl I30 and! which would thereupon expand and in the hardening material around them formpo'ckets. y
In this instance the temperature is ordinarib run up higher than would be normally used so that a maximum degree of expansion can be obtained. The formation of these pockets which will always be present in the plaster, for example, will provide room for any subsequent expansion and contraction that may take place in the distribution system in ordinarytuse and thus will be avoided unnecessary cracking of the plaster.
I claim:
1. For use in heat exchange system wherein secondary tubing is connected with primary tubing, a connection comprising: a tubular member having a port in its wall, and a ported conductor member secured to said tubular member transversely thereof with the axis of the tubular member beingsubstantially tangential with the bore of the conductor member, the ports of the two members being positioned for fluid intercommunication from one member to the other member.
2. A connection comprising: a tubular member having a port in its wall, and a conductor member having a port in its wall, said conductor member being secured to said tubular member transversely thereof with the bore of the conductor member being inset into the bore of the tubular member and the ports of the two members being in position for fluid intercommunication from onemember to the other member.
3. A connection for use in heat exchange systems, said fitting. comprising: a body having a fluid conduction passage therethrough, said body having a second fluid conduction passage therethrough transversely of the first passage, the axis of one of said passages being substantially tangential with an edge of the other passage.
