CHARLES WALKER, OF KNOXVILLE, TENNESSEE.
DRAINAGE srs'rarr,
Application filed June 8, 1910. Serial No. 565,824.
To all whom it may concern: 7
Be it known that I, CHARLES WALKER, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented new and useful Im rovernents in Drainage Systems, of which the following is a specification.
This invention relates to improvements in drainage systems for water service pipes and it pro oses a system wherein by the opening 0 a suitably constructed drain valve, all the pipes in the building including those that are trapped, are com letely drained, and without the necessity 0 open ing the several faucets, and wherein the draining of the hot water boiler is automatically prevented beyond a prescribed limit. As an incident of the system the invention proposes a'means to provide for the instantaneous delivery of hot water.
An embodiment of the invention is illustrated in the accompanying draw ngs, wherein- Figure 1 is a diagram of the system; Fig. 2 is a detail sectional'view illustrating the arrangement of a valve to be hereinafter specifically referred to; and Figs. 3 and 4 are sectional views illustrating alternative features of construction which may be embodied in the system.
Similar characters of reference designate corresponding parts throughout the several views.
The water is admitted to the building through. a pipe, as 1, between which and the main distributing plipe 2, a drain valve,
his drain valve is preferably of the construction shown in my co-pending application, Serial No. 545,915.
The hotwater boiler is designated by the numeral 4 and the cold and hot water faucets are designated by the numerals 5 and 6 respectively. The cold water faucet 5 is connected with the pipe 2, by a pipe, as 7, which is continued to a point above the faucetJ5 and which is connected with the latter by a depending pipe, as 8. The boiler 4: is connected with the pipe 2 by a pipe, as 9, in effect a continuation of said main istributing pipe 2 and from which depends a pipe 10 which projects into said boiler and which, a short distance from the upper end of the boiler, is provided with a small opening 11. The boiler is, in turn,
also with a pipe,
connected with the hot water faucet 6 by a pipe, as 12.
In some cases it may be desired to completelydrain the boiler. For this purpose a casting, as 13, is threaded intothe lower head of the boiler and is rovided with a discharge way, as 14, which is normally closed by a valve, as 15, the stem of which is threaded through casting 13.
The water back is shown at 16 and the connections thereof with-the boiler are of special character. The inflow connections of the water back consist of pipes 17 and 18, connected at their upper ends by a curved union 19 and forming in effect an inverted U tube. The ipes 17 and 18 are confined within the boi er and the pipe 18 is secured in the casting 13 aforesaid, and communicates with the pipe 20 which is also joined to said casting on the outside of the tank and which leads directly to the water back. The outflow connections of the water back consists of piping 21, the end section of which projects into the boiler and therein is connected to an upstanding pipe, as 22, which is in turn connected to a pipe, as 23,
by a union 24, the latter being associated with the upper end of the pipes 22 and 23. The preferred construction of this union is shown in Figs. 1 and 2 wherein it will be noted that the union forms also a casing to inclose a sector valve 25, the stem of which is passed through a bushing, as 26. The latter is joined to the union 24 and is secured in the wall of the boiler b a suitably packed joint. The stem 27 of t e valve 25 projects through the bushing 26, and on thl exterior of the boiler carries a hand wheel 28. The valve 25 controls the communication of the union 24 with the pipe 23 and as 29, which communicates with the upper portion of the boiler and adjacent to which a small opening, as 30, is formed in the union. The union 19 is provided with a small opening, as 31, for a purpose which will presently appear.
the lower end of the Specification of Letters ram. Patented June 20. 191 1.
The trapped pipes of the system are conof the boiler through the pipe 2!).
Normally the water from the pipe 1 passes through the valve 3 and to the cold water faucet 5 by way of the pipes 7 and 8 and to the boiler 4 by way of the pipes U and 10. The water thus admitted to the boiler circulates through the water back, being returned from the latter to the boiler, and is drawn ofi' by the faucet (3 through the pipe 12. In case it is desired to heat the water in the usual manner, the valve 5 is positioned as Show, as closing the ipe 29 so that the water returning from the water back l'lows into the boiler through the pipe 23. But in case an instantaneous supply of hot water is desired, the valve 25 is turned to close the pipe 23, in which case the water from the waterinwk is delivered into the upper palrt T 1e movements of the valve 25 in either direction are limited by lugs, as 230. \Vhen the valve 3 is turned to interrupt the communication of the pipes t and 2 and to drain the system, the water in all the pipes will be drained. The pipes SJ and 7 drain through the pipe 2, while the trapped pipes drain through the pipes 32, and 34. The latter pipe also drains some of the water from the upper portion of the boiler. The amount of water thus drained from the boiler th rough the pipe 34 is determined by the position of the opening 31. It; will also be apparent that that portion of the pipe 10 between the upper end of said pipe and the opening 11 is also drained as well as the union 2t and the pipes 22 and 18, the water back and the connectionsv thereof. In Fig. 3 the piper-5Q? and 23 are connected by a union as 24 which,
is similar to t-h'iinion 1t) and is provided with a small openitjg 30*. This construction is not adapted for the instantaneous delivery of heated water, the opening 30 providing simply for the drainage of the pipe 22 and the union 24.
In.Fig; 4 there is shown an alternative construction in which the pipes 22 and 23 are connected by a union 24 generally similar to the union 24 but provided with a large opening 29 and a small opening 30*. The opening 29 is of a diameter equal tothe diameterof the pi 22 and is provided to deliver hot water directly into the upper end of the boiler, as when an instantaneous delivery of,h0t water is desired. By closing this opening, hot; water is caused to discharge into the boiler through the pipe 23.
The means for closing the opening 29 consists of a stem 37 which is threaded through the upper head of the boiler.

main supply pipe and a drain valve interposed between the pipes, of a boiler, a pi e connecting the boiler and the main sup y pipe, a water back, aninvertcd U pipe disposed within the boiler and connected to the 4 water back, the U pipe having a small opening at its upper end, a return connection between the water back and the boiler and a drainage connection between the water back and the valve.
