This invention relates to improvements` in adjusting units for heating systems. More especially it relates to units for adjusting the iioW of a medium, as hot Water, to the radiators of the system, severally, tothe end that the volumeof flow through each radiator may be in approximate equality with or atleast in a desired proportion to, that through other radiators ofthe system. f f

The vimprovements herein disclosed and claimed are particularly adapted oruse in a control system such as is described in application for Letters'Patent, Serial No. 178,364, filed March 25, 1927,- inthe name oit Albert 151 W. Moulder for improvement in "heating systems. A .The present inventionk provides an elongated resistance for the flowing medium, which is insertable in the regular piping at each radiatorvvhere it is desired, having several improvements among whichy are the at-` taining of the total desired friction in a very short distance; the standardizing of the resistance element as to length, however their individual resistance valuesl may be adjusted, and the providing for extremely easy andpquick adjustment ofV the resistance,in as iine gradations as may b ey desired. These ends are attained withk usel of capsule wherein is Van elongated path for the medium (assumed herein toV be hot Water) and an ef` iective means whereby the flow of Water may be delayed by impact and its course at the same time' being made more meticulously tortuous, sothat the degree 'of frictional resistance required may be obtained in a small space, Without the fiovv being seriously obstructed., Itis also a feature that the resist-k ance unit as a Whole comprises a multiplicity offparts, which may be either restricting parts or non-restricting parts and Which may be easilyarranged in place and in such proportionatenumbers as are requisite to'obtain the M ,A eiiect desired.y A 45 vllheinvention provides, as does thatof Mr. Moulder, for the insertion of the capsule as va unit'inside of the piping constituting the local circuit ofeach radiator, being preferably inserted through the radiator valve into the end of the feed pipe yWhich leads to 1927. serial No. massa merely a sleeve or tube and might be composed of .any other suitable holding means, are certain perforated flanged disks superimpos y one` upon another with their flanges thusiitting Within 'the tubes and their bodyportions extending across the tube. In. a pre-K ferred arrangement for getting maximum' resistance disks having a centralperforation Y alternatev with" the disks having perforations near their flanges. j' The flanges ,are short, cylindrical', and have the elliectcf' spacing' the body Apart of one disk fromthe body` part ot the next adjacent disk. 'InV practice these ianges'are short fandconsequently the successive'disks are relatively close together.A Since thepclosed portion of each ydisk isfin line with the opening of the precedingI disk and of the succeedingdisk, the Water-passing through an opening is impacted against thel disk space as a barrier and must turn sharply aside in eddy current to lind the nent opening. The frictional vresistaime imposedupon the, flowing `Water can be varied asl'desired, Within a relatively short distance, by suitably ar-` ranging the number olfV alterations of one kind of disk to the other kind, ythe maximum being had Where'every passagefrom one disk to-anotheris an alternation, and 'a minimum resistance-Where there is no alternation, all

disks beingof the same kind, unless, as a further measure to reduce resistance, the capsule is omitted altogether-` f A'In the construction or adjustment of the heating system oneniay first determine Whichy of the .radiators will have excessive flow, this determination being made byv computation or by operation, andthen suitably arranged resistance capsules may be inserted, one in the local circuit of "each radiator providing such resistance as is neededat the radiator to make the total resistance of flow through its circuit from the source of heat through the radiator and back to the sourceot heat substantially equal to the total resistance to flow through each otherradiator circuit, in which case there Will be an equable iioiv ofthe heat? ing medium through all parts of the system.

It is intended that the patent shall cover by v suitable expression in the appended claims whatever features of patentable novelty exist in the invention disclosed. l Y

Referring to the drawings: Figure l is an elevation of a radiator and feed pipe leading thereto, with a part of the latter broken away to show the restrictionV unit therein, y

Figure 2 is an elevation, on larger scale,

`with parts ,in section, of :the feed. pipevalve and restriction unit; Y .v

Figures 3 and el are plans and elevations 0f the different types of disks used in the rex striction unit;

' Figure 5 is an elevation of a section of the nunit on still larger scale, illustrating an imagined course of flow of the water through the disks; and ,e

Figure 6 is an elevation like Figure showing a modified formof disk.; v

Referring `to the drawings, radiatorlO receives hot water through the feed pipe l2 and returns it through pipe lll. vrlhe restriction unit 16 of the present invention is inthe tube with their flanges 24a against itswall.

lthrough the opening in thelowest Each alternate disk has a central perforation 2li in its body being thebottom Vof the cup, and the intervening disks have one'or more marginal perforations 24C distributed about the edges of their-.body portions, Vnear their flanges. The tube and its contained disks makeV a sort of capsule or cartridge 'which can be previously loaded with disksuas desired and then inserted while the valve is temporarily removed. As seen in Figure 5 water iollowing up through pipe l2 must enter the bottom of the sleeve 2O and'pass disk, assumed to bea central opening 24". lhe diect course upward throughV this opening strikes the' solid center 2451 'of thejdis'k nent above, so that the-water must separate, and spread toward the flange 24?- of the disk, where it isagain arrested and must turn togo through the marginal openings 24C only to strike the solid partv 24e of a disk like the first one. The abrupt deflections create eddy currents and set up a turmoil between the a disks. Ultimately the flow gets through the stack ofdisks, but only after overcoming the resistance engendered by repeatedly -changing Yits course thus radically and circularly s and passing over the more or less sharp edges Y walls, inertia, eddying, etc.

of the openings, with considerable friction and absorption of energy due to the endless opposition from liquid tension, adhesion to The degree of his opposition to flow is in proportion to the number of alternations of the-two kindsof diator,and back to the source shall have a supplemental resistance, supplied by the de- Vvice of the invention, which puts it on an equality with the other radiator circuits,or it such relation' thereto as may be desired. `Yet there is'iiowhere a dangerous -Iclosure of the flow passage; tlievalve may be operated to turn its radiator off or on at will. Subsequent adjustments can easily be made if desired.

Above the uppermost disk is a coiled spring 2G which is somewhat compressed by the valve -18 even when the latter is full open. The spring pressure holds the disks inthe tube andthe tube inthe pipe against theupward flow of water. i'n case .a eonsiderablernumber of ,disks were removed, afspacingtube (not shown) equal tothe fianges 2 4 in diam-A eter and thickness, andas longV as desired,

could be inserted under the top remaining f disk so that the spring could-always exert this pressure ou the rdisks and tube.

Y It is a' feature of the arrangement that a` very great amount of resistanceV to 'flow is made available in a short lengthofpipe. The number of disks can be veasily, changed, and consequently the resistance raised or lowered quickly to meet any observed need. y

In Figure 6, a modified form of. disk is shown in which the solid part V 24? around the central perforation 24h is dished or in-v clined toward the i'iange 24a. .lVith vdisks so shaped and inserted in the tube 20,' with the dislied portion` 219 downward, the water which naturally spreads to someextent after passing through an opening 24. is further spread by its contact with the inclined surface of thedisk, and directed against the liaiiges 24D. The impact with the latter Causes the water to turn back upon itself, setting up a turmoil and forming eddy curentswhich effectually cut down the velocitypf fiow through the central openings.

i e claim as our invention: Flow impeding means fora hot water heating system comprising'in combination, a tube adapted to .beinserted in the local piping circuit of a radiator so that the water flowing through the radiator passes through said tube; a multiplicity of disks each having a perforated body portion extending across said tube and having a marginal flange fitting against the wall thereof and resting against the next adjacent disk to provide a "space between the disks ;v alternate disks having a. central perforation through their body portions and the intervening disks having marginal perforations through their body portions whereby the water passing through the perforations repeatedly suffers impacts and deflections; the said spaces between the disks having capacity of flow at least equal to the capacity of kflow through the perforations.

2. Flow impeding means adapted to be ina marginal perforation; and the said disks being spaced apa-rt to provide a passage between each disk as large as the passage through the perforations thereof.

3. llhe combina-tion with a valve for the radiator of a hot Water heating system, of a tube having an outturned flange at one end adapted to rest on the Valveseat and having an inturned fiange at the other end; a series of flanged disks nested in said ltube With the flange of one disk resting on said inturned flange and With the flanges of the succeeding disks resting on the body portions of preceding' disks; each alternate disk having a central opening and the intervening disks having a marginal opening whereby the hot Water passing through the series of disks repeatedly suers impacts and deflections.
