Patented May 3, 1932 PATENT ori-ICE i PERRY s. MARTIN, or IIARnIsoNBURG, VIRGINIA MANIFOLD Application led January 14, 1928. Serial No. 246,801.

My invention relates to manifolds, and more particularly to a manifold for use in connection with heating systems of incubators, broeders, etc., whereby hot water or steam is circulated through heat radiating pipes, said manifold having separable `compartments andrconstructed and arranged for properly supporting one end of each pipe of a plurality of flow and return heat radiating pipes, said flow and return pipes communicating with separate compartments of the manifold and with the outer ends of the flow pipes communicating with the outer ends of the return pipes.

Another object of the invention is to provide a manifold of the above mentioned character constructed in a single piece, having a plurality of pipe tappings thereon in line with one another and arranged on an angle, and a partition extending longitudinally of the manifo-ld dividing the same in two separate compartments, and with alternate tappings communicating with the same compartment so that hot water to the flow pipes and cool water from the return pipes are kept entirely separate.

A further object of the invention is the provision of a two-compartment single-piece manifold for not only reducing the cost of manufacture thereof, but for providing positive or fixed positions for both the flow and return pipes so as to eliminate difficulty in properly assembling the different units of a heating system, this being an improvement over the use of separate manifolds, as it is an easy matter to get the manifolds out of alignment and thus experience trouble when assembling the units in a long incubator or brooder where several lengths of pipes are used for forming a single flow or return pipe.

It is also an object of the invention to provide a device of theabove indicated character, which is simple and substantial in construction, which can be manufactured economically, and which will be thoroughly efcient and practical in use.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as

hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

igure 1 is a perspective view of my improved manifold, showing portions of pipes connected therewith,

Figure 2 is a longitudinal vertical section through the same, and

Figure 3 is a longitudinal section taken on line 3-3 of Figure 2. y

In carrying out the invention, the numeral designates my improved manifold generally, which has a pair of side walls 11 and 12, a top wall 13, an end wall 14, and an angled bottom wall 15, which extends from the lower portion of the end wall 14 in an inclined direction to one end of the top wall 13. Arranged in alignment on the side wall 12 and at an angle slightly less than the angle of the bottom wall 15, is a plurality of pipe tappings 16, which are threaded and adapted to receive the threaded ends of a plurality of heat radiating pipes 17 for forming connections between the heat radiating pipes and the manifold and for supporting the ends of said heat radiating pipes. v

Extending longitudinally of the casing of the manifold is a partition 18 which is at-y tached to the opposite side walls 11 and 12 and is of a corrugated construction so as to lie upon opposite sides of adjacently arranged tappings 16, said partition being clearly illustrated in Figure 2 of the drawings. The ends of the partition 18 are attached to the end wall la and the point of connection of the inclined bottom wall with the top 13 so as to divide the interior of the manifold into two compartments, namely a heat flow compartment 19 and a return compartment 20. By this arrangement it can be seen that every other one of the heat radiating pipes will be in communication with the same compartment and that the heat radiating pipes which lie adjacentV one another are in communication with the separate compartments.

On the side wall A11 of the manifold adjacent the end wall 14 is arranged a pair of pipe tappings 21 and 22, the tapping 21 communicating with the inlet compartment while the tapping 22 communicates with the outlet compartment. In the tapping 21 is connected by means of screw threads or the like a hot water supply pipe 23, while in the tapping 22 in a like manner is connected the cool water return pipe 24. It thus can be seen that each of the compartments 19 and 2Q have either an inlet or outlet pipe connected therewith. rIhe tapping 22 is arranged a'tvl'the lowermost point of the compartment 20 so as to assure complete drainage of the compartment when desired. ,y y

As the partition 18 is'ofacorrugatd'construction, I have arovi ded a series of taps 25 at the vlowermost points of the compartment 19 so that saidcompartment may be tapped in orderto drain same when desired.

As the pipe tappings are arranged alternately with respect to communication with the compartments, it can be 'seen that every other one of the heat radiating pipes 17 will be heat flow pipes and the other heat radiating pipes will be cool water return pipes, due to the fact that the outer end of each flow pipe is connected by means of a return bend 26 to a return pipe adjacent thereto.

It is tobe noted that by arranging pipe tappings 16in alignment and havingthe partition 18 of corrugated construction heat radiating pipes will be in aligned parallel position and that the aligned heat radiating pipes are at a slight angle, which makes this manifold particularly adapted for use in connection with brooderssuch as that shown in my Patent No. 1,592,877 and my pending application` entitled Colony broeder, .led January 21, 1927, Serial No. 162,527'. Furthermore, it is to be noted that by constructing a. two-compartment single-piece manifold the desired angle of all the pipes as well as the proper positioning of the pipes is easily had, as well as providing a structure whereby the pipes f-ormingthe heatradiators may be cut the desired length and all the same so the equipment can easily be knocked down for shipment and can be readilyv assembled vand erected by inexperienced parties. As previously mentioned, two-piece manifolds have been used, but quite 'a little trouble has been experienced in properly assembling a heating unit using such manifolds. In my device all points of connection with the manifold are fixed. rIhus when the pipes are connected to the manifold they will be in proper position. In a two manifold system having a flow manifold and a return manif-old used in connection with long incubatorsor brooders where there 'may be several lengths of pipes in a single ow or return pipe, itis customary to first connect the pipes'to the return manifold and then later connect the pipes tothe fi'ow manin fold, and when this is accomplished to connect the fittings from the heaterto'the manifold.

In doing this, it is an easy matter to get the two separate manifolds, namely the flow manifold and return manifold, out of alignment so that trouble is experienced in assembling the fittings to the heater.

As the hot water supply pipe 23 is connected to the flow compartment 19, hot water will enter said flow compartniengtiandilow thiough every other one of the heat radiating pipes, due to the fact that levery other one of the heat radiator pipes are.' in communication with the flow compartment. As the outer -ends'of the heat flow pipes are connected by means of return bends to return pipes, the water'will 'return 'inevery other one of the heat radiating pipes andtlow intothe'return compartment 2O ofthe manifold. lFronrthe ret-urn compartment '20,I =the Water l`flows through the return pipe 211 to the heater and thus complete circulation is had.
