COMBINED CONDENSER AND REBOILER.

Specification of Letters Patent.

Application filed November 3, 1913. Serial No. 798,814.

To all whom it may concern:

Be itknown that I, PRESTON H.- SELLERS, a citizen of the United States, and resident of East St. Louis, St. Clair county, Illinois,

have invented certain new and useful Ima provements in Combined Condensers and Reboilers, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in combined condensers and reboilers, and is I more particularly directed toward the form of condensers shown in my U. S. Letters Patents No. 835,260 and No. 962,789 granted November 6, 1906 and June 28, 1910 respec-.

tively.

The object of my present invention is to combine in one structure a reboiler with a steam condenser in order to utilize the heat from the steam to be condensed for reboiling 321 having at its uppermost margin a flange the water of condensation from said steam.

with the above purposes in view my in-' vention consists in certain novel features of construction and arrangement of parts. as will be hereinafter more fully described,

tion of a combined condenser and reboiler 1 constructed according to my invention;

Fig. 2 is a transverse sectional elevation, and Fig. 3 is an end vlew of the structure steam pipe 24; 1s an opening 25 forming a as shown in Fig. 1. I

Referring by numeralstothe accompanying drawings: 4 and 5 designate the side tion. The sides 1 and 5 are united at their upper margins by means of rivets or bolts 6 and the lower margins of the sides 4 and 5 are provided with flanges 7 Secured within and adjacent each end of the condenser body is a head 8 and within said body preferably uniformly spaced apart are the alternately short and long bafiie plates 9 and 10 respectively, the short iafiie plates extending from the bottom of the condenser body to a point near the top thereof and the long bafl'le plates more nearly (but not wholly) forming a complete baffle than the short plates. In each of the short plates 9 and at their lowermost ends are the openings 11 and in each of the long plates 10 at their lower ends are the openings 12which are of greater size than the openings 11.

13 designates a plate forming the bottom of the condenser body as well as a top for the reboiler 14 which depends from the plate 13 and is secured thereto by means of the bolts 15 which bolts extend through flanges 16 formed on the margins of the reboiler 14, and to prevent leakage at the oint between said flange 16 and the plate 13 there is a packing strip 17. i

18 .designates a shell which is substantially semicircular in cross section and provided at its upper margins with flanges 19.

r The flanges 7' of thesides of the condenser .body, the plate 13 adjacent its margins and the flanges 19 of said shell are provided with registering bolt openingsfor the bolts $20 in order to form a structure which may be readily assembled and taken apart.

At each end of the shell 18 there isa head l22which is detachably secured to the plate 13 and the heads 8 of the condenser by @means of bolts 23.

isaid joints packing.

ipipe leadsjto the exhaust of a steam engine. Inthe plate 13 opposite the end having the Patented Sept. 3, 1914..

In order to form steam-tight joints beitween the parts just described I resort to; ithe' common expedient of placing at all of l v 85 2 1 designates a steam pipe in communijcation with the shell 18. Usually this steam lcommunication between the shell18 and the condenser body. x

thehead 21 of the shell and communicat ;ing with th'einterior of the reboiler at a point in a plane beneath the plate 13. This pipe leads to a point of consumption, such as a tank for the supply of freezing cans. By placing the pipe27 in a plane'removed from the plate 13 there is automatically maintained a space between the water level in the reboiler and the plate 13. Secured to said plate 13 and in communication with the reboiler is a pipe coupling member 28 and detachably connected with said pipe con- 26 designates a pipe which leads from the pling member is a ventilating pipe 29 which.

extends to a point outside of and preferably adjacent the top of the condenser body.

30 designates a drain cock in communication with the reboiler and extending through the shell 18, and 31 designates a drain cock in communication with the shell. These cocks are, of course, normally closed when the condenser and reboiler are in operation and are used only when'it is desired to clean or repair the condenser and reboiler.

Carried by the head 8 of the condenser body at a point over the opening 25 which is the steam inlet to the condenser body is a check valve'32 which is normally closed to atmosphere, but which would be open in the event of an excess steam pressure in the condenser.

In the head 8 or" the condenser body and at the end removed from the steam inlet 25 isv a check valve 33 which is normally open to atmosphere in order to admit air to the condenser body to counteract the tendency toward a vacuum created by the condensation of the steam.

Secured to each of the heads 8 of the condenser body adjacent their tops are the brackets 3e and carried by said brackets are the pipe hangers 35, each of which is threaded at its lowermost end to receive the nuts 36 whereby each of the hangers may be adjusted vertically relative to said brackets.

Supported in the pipe hangers 35 and extending the full length of the condenser body at a point directly above the apex is a pipe 37 provided with aslot 38 at its top. Carried by said pipe and in communication therewith are the tunnels 39 which com-H municate with a source of water supply, not

shown.

40 designates straps embracing the pipe 37 at its bottom, and the deflector at its lower margins stands over the apex or upper margin of the condenser body.

hen water is applied to the tunnels the pipe 37 is filled and overflows through the slot 38, an equal amount of water flowing on I either side of the pipe, the deflector carrying J the water in equal volume over each side of the condenser body. The flanges 7 at the bottom of the condenser body deflect the water so that it does not flow over the shell 1 18. Assuming the water to be flowing as just described steam is admitted through the pipe 24 into the shell surrounding the reboiler. After having traveled the length of the reboiler and shell the steam enters the condenser through the opening 25 where it is caused to travel a comparatively long tortuous path to the opposite end 01": the condenser body. Here the steam is converted into water, or in other words, condensed due to the coolin effect of the body of water flowing over the condenser. The water of condensation flows into the reboiler through the pipe 26 until it has filled the reboiler to the height of the overflow pipe 27. The steam, entering the pipe 24 and traveling the length of the reboiler, reboils the water of condensation and in such reboiling the foul gases and odors are carried ofl through the jventilating pipes 29.

It is to be observed that the pipe 26 from the condenser conducts the water to a point near the bottom of the reboiler where it will be in a position to receive the heat from the ;exterior of the reboiler.

' I claim:

1. In combination with a condenser, and a ishell arranged to receive steam and conduct it to the condenser, a reboiler within said =shell,.arrangedto reccivewater of condensation from the condenser, said reboiler holding its body of water to be reboiled where it will be subjected to the steam passing through the shell, but not in communication therewith, and also holding said body of water where it will not be influenced by the cooling action of the condenser.

2. In an apparatus of the class described, a condenser, a shell located beneath the condenser, means for admitting steam to'said shell, means for placing said shell in steam communication with the condenser, a re boiler within said shell completely closed against the admission of steam, means for admitting water of condensation from the condenser to the reboiler, means for draw- :ing the reboiled water from the reboiler,

' having its intake ends beneath the condenser to provide a space within the reboiler and means for ventilating said space. In testimony whereo' I have signed my name to this specification, in presence of two subscribing witnesses.
