MARSHAL I). TILLIVIAN, OF WABASI-I, INDIANA, ASSIGNOR TO TILLIVIAN HEATING- DEVICES COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORATION OF INDIANA.
PIPE-FITTING.
Specification of Letters Patent.
Patented Dec, 12, IWL' S.
To all whom it may concern Be it known that I, MARSHAL D. TILLMAN, a citizen of the United States, residing at Wabash, Wabash county, and State of Indiana, have invented and discovered cer tain new and useful Improvements in Pipe- Fittings, of which the following is. a specification.
My invention relates to pipe fittings and particularly to a pipe fitting which is adapted to be used in hot water heating systems at any points of connection between a horizontal feed line and branch lines leading to devices to be supplied with hot water such, for instance, as heating radiators.
The objects of the invention are to insure that the water separately'fed from the distributing line to the branches at the successive points of connection of the latter with the feed line shall be of approximately uniform temperature so as to prevent the feed to the branch pipes that are nearest the source of supply from robbing the distant branches of the hotter portion of the water; to enable this result to be accomplished by a construction which avoids the use of extra pipes for connecting the distributing and receiving lines and to avoid the necessity of a construction which will produce a trap in which the water will collect and from which it must be removed when the plant is closed, and to provide means whereby the above results may be carried out through the use of an integral structure which is of low cost in construction and easy to install.
In hot water heating systems it is usual to em loy a main distributing pipe which extend s substantially horizontally and from which branches lead to the different floors to be heated and from these branches it is also usual to employ sub-branches for each floor which are in turn connected to a number of radiators on the same level. In the horizontal pipes used for distribution and for the branches which, lead to the radiators, the hottest part of the water conveyed thereto rises to the upper parts of. the pipes, leaving a colder portion at the bottom. In the. early use of hot water heating systems it was found that the ordinary connection be tween the horizontal distributing pipes and the branches or radiators served to draw off the hotter portion of the water through the branches nearest to the source of supply,
the heat of the remaining water gradually diminishing as it approached the receiving means farthest from the said source, which action frequently resulted in leaving the radiators last to be supplied, completely cold. Various methods have been put in use and proposed with a view to overcoming this difficulty but several objections exist thereto. The present device seems to overcome these objections.
My invention is embodied in preferable form in the construction hereinafter described and illustrated in the accompanying drawings.
In these drawings, Figure l is a front view in elevation ofa pipe fitting embodying my invention; Fig. 2, a side view; Fig. 3, a section on line 3-3 of Fig. i, and Fig. 4, a cross section.
Referring to'the drawings, 1 indicates the main hollow body of the pipe fitting and it is adapted to join the two sections of a horizontal distributing or feeding pipe by which hot water is to be conveyed to various branches located at suitable intervals along said pipe, and this body constitutes a conveying section for the hot water. This body has, preferably cast integral with the same, a lateral horizontal extension 2, which at its outer end is circularly formed to pro vide a. connecting collar 3 which forms an exit mouth for the water and is interiorly threaded to receive the threaded end of a branch receiving pipe 4. This extension projects from that portion of the distributing pipe which is below the center of the latter, the outer lower edge of the extension 2 being substantially tangential to the outer circumference of the distributing pipe.
The shell of the body 1, at the point where it joins the extension 2 is provided with an inwardly and downwardly extending abutment lip 5, which projects to a point considerably below the center of the main body 1. and is adapted to close the upper portion of the chamber 6 formed in the extension 2 against the entrance of water, so that the communication of the branch pipe will be only with the lower portion of the main distributing pipe, thus serving to admit only the cooler portion of the water at the bottom of said pipe from the same to the branch.
As seen in Fig. 1 the passageway 7 thus formed between the lower fiat wall of the A the delivery pipe shall come only from the extension '2 and the lip 6 is substantially rectangular in shape and is wider than the horizontal diameter of the branch pipe 4 connected to the collar of the extension. This passageway throat is made of exactly the same cross area as that of the said pipe 4 in order that the distributing pipe may freely feed 'anamount of water to the branch pipe equal to the capacity of the latter. The cross area of'branch pipe 4: is
of course much less than that of the conveylng section 1 of the fitting.
In order to enablethe abutment lip to be carried. downwardly as far as possible and to further insure that the water fed from lowest portion thereof, a recess 8 is cut in the interior surface of the lower flat wall of the extension 2. r I
With the above described arrangement, it is evident that the water supplied to the branch pipe t from the delivery pipe through the main body 1 will be drawn from such main body at the lowest portion thereof and below the center of said body so that the cooler portion of the water will always be drawn off and hence the hotter part of the body of water not robbed by the branches nearest to the source of supply and short circuiting of the water around the first radlator prevented. Thls construction avoids the use of extra pipes, traps and pet cocks to accomplish the above'end and also provides a fitting which may be readily cast in one piece and easily applied atlthe point of desired connection.
Having thus described my invention, what I claim is:
low main conveying body and having a branch, the axes of said body and branch lying in horizontal planes, the passageway of said branch extending horizontally from its. inlet to its outlet and below the axis of the main pipe, said branch having means to communicate with a' receiving pipe, the cross area of the branch passageway and the inlet of the receiving pipe being equal.
. 3. A pipe fitting having a conveying channel adapted to communicate with a distributing pipe and having a lateral branch in communication with the main body of the fitting and provided with a passageway tangential at its bottom to the channel of the said main body, the axes of said passageway and channel of the main body lying in horizontal parallel planes.
A pipe fitting having a conveying horizontal hollow body portion, a branch pipe adapted to connect with a receiving pipe and having a horizontal axis throughout its length of less cross area than that of said body portion and adapted to communicate horizontally and tangentially with said body and exit passageway means leading from said body portion below the center thereof with the bottom surfaces of the passageway and body portion substantially level and having the same cross area as the branch pipe, substantially as described.
5. A pipe fitting having a hollow conveying section, a lateral part leading horizontally and tangentially from the lower portion of said section and an abutment projecting downwardly into the passageway between said section and part, substantially as described.
6. A pipe fitting having a hollow conveying section, a lateral branch having its bottom surface leading horizontally and tangentially from the lower edge thereof, an interior abutment projecting downwardly into the passageway between said section and said branch, the outlet from said branch and said passageway having the same cross area, substantially as described.
7. A pipe fitting having a hollow conveying section, a lateral branch leading horizontally and tangentially from the base of said section and having communication therewith at one end and communication with a receiving pipe at the other end, an abutment projecting downwardly from the section into the passageway between the same and the branch and restricting said passageway to a space below the center of the section, said passageway being of greater width than the outlet at the receiving pipe, but of the same cross area. as said outlet, substantially as described.
In witness whereof, I have hereunto set my hand and seal at Indianapolis, Marion county, Indiana, this 27th day of May, A. D. nineteen hundred and fourteen.
