Patented Oct. 12, 1937 s mi com) WATER INLET son DOMESTIC corneas 3 Claims.
This invention relates to improvements in equipment for domestic hot water boilers and pressure tanks and contemplates an assembly in which the cold water tube is formed of a plurality of telescopic sections, each free to move within its adjacent companion section and provided with screw threaded portions whereby after adjustment the sections may be secured in position.
More specifically the invention includes a series of sections each formed with an outwardly flared upper end for engaging with the inwardly projecting lower end of the adjacent section when in their extended position and in addition the co-acting sections are each provided with cooperating threaded portions whereby they may be secured when in their extended form.
The present invention further provides a first section having suitable threads at its upper extremity for connection with conventional pipe unions and threaded and flared at its lower extremity for cooperation with the adjacent telescoping section. Intermediate the end structure there is also formed the usual opening to eliminate syphon action which would otherwise be present when the assembly is in operation.
Other objects and advantages will more clearly hereinafter appear by reference to the accompanying specification, claims and drawing wherein like characters designate corresponding parts throughout the several views, in which- Figure 1 is a side elevation partly in section showing the present invention in its extended form. V
Figure 2 is a side elevation showing the assembly in its collapsed form.
Figure 3 is a transverse section of line 3-3, Figure 1, and
Figure 4 is a view of a boiler end in perspective showing the invention in position.
Referring now to Figure 4, the domestic hot Water boiler or similar tank is illustrated by reference character A, this tank being provided with the usual opening a. in which the cold water inlet is arranged. The structure at this opening may be of conventional type and suitable to insure a proper sealing of the joint against accumulating pressures. The reference character B designates generally the collapsible or telescopic cold water supply pipe which is, the substance of the presentdevelopment. This telescopic supply pipe is formed of. a plurality of sections, the number to be determined by the requirements in the case and the length of the sections in question, it being essential in a boiler or tank assembly that the outlet of the cold Water supply be at a definite predetermined position as regards the bottom of the tank.
Each of the intermediate sections forming the cold Water supply inlet is formed to include the same structural details including a body portion terminating in an upper outwardly flared end portion C. The flared end thus will snugly engagethe suspended section in a leak proof manner. The lower extremity is beaded inwardly at cl to engage the adjacent section and align the parts during adjustment.
The upper section is the largest, its lower end corresponding with the lower ends of the intermediate sections, and the upper end F receives a dome-shaped tapped connection G which may be welded in position. The threads 9 0f the connection are formed within the body of the connector element G, and are cast integral therewith. An opening 7 is provided in the wall F of the upper section to eliminate syphonic action. The cap G is inverted into tank A and is suspended therein by a standard threaded nipple attached to the standard boiler coupling, which in turn seals the tank.
The lower section is merely formed witha flared angular upper end which cooperates with the threaded lower portion of the adjacent upper section.
It is contemplated that in commercial use this telescopic pipe unit will be made up in various sizes to permit adaption to various tank equipment. When being positioned in a tank it will first obviously be necessary to consider the length oi: the tank body and the desirable position of the cold water inlet. Having determined this any two or several of the units or sections may be telescoped and threaded together so that the length of the assembly will when placed in position reach to the desired point in the boiler. This inlet position may be changed as desired in accordance with requirements.
In marketing the invention it may be transported in totally collapsed form as shown in Figure 2 with proper markings to indicate the limit of extension possible in each unit.
If necessary packing may be provided between the sections, this packing to be of suitable form to eiiect sealing without interfering with the adjustment of the sections.
In constructing the assembly the sections are assembled in their regular order beginning with the smallest and finally the smaller sections are inserted within the top or larger section and the place. Due to the nature of the tubing of which the assembly is formed it has been found advisable to roll the threaded and beaded extremity into shape and this can be done at a single operation. The number of sections, the length of the sections, and other details may be varied to suit requirements in different instances, it being only necessary that the elements comprising the struc ture include the parts heretofore described and be formed of suitable non-corrosive material which will maintain the assembly clear and open under all working conditions.
What I claim as new and desire to secure by Letters Patent is:
1. A cold Water inlet pipe for domestic boilers comprising an upper section, a lower section, and intermediate sections, the upper section and the intermediate sections each being formed adjacent their lower ends with a threaded portion, each of the intermediate sections being. provided at cap carrying the standard thread is welded into their upper extremity with an outwardly flared portion for engagement with the threaded portions of the upper adjacent sections, and a reduced threaded socket fixed to the upper end of the upper section.
2. The substance of claim 1 characterized in that the upper section and the intermediate sections are each of reduced diameter below the threaded portion to form an annular shoulder for engaging the flared upper extremity of the lower adjacent section.
3. The substance of claim 1 characterized in that the upper section and the intermediate sections are each reduced in diameter below the threaded portions to provide a supporting annular shoulder for engaging the flared upper ex tremity of the lower adjacent section and means are provided for clamping the flared portions in engagement with the shoulders.
