Specification of Lettere Patent. l

- Patented July ai, rece.

To all whom it may concern:

Be it known that l, NATHAN P. Towne, a citizen of the United States, residing in the city and county of Philadelphia, State `of Pennsylvania, have invented a new and useful Condenser, Distiller, and Feed-Water Heater, of which the following is a specification.

lt is well known thatin surface condensers, dietillers, feed water heaters, and the like it requires much more y than the theoretical amount of condensing-surface to condense a certain quantity of water; and my present invention relates to a novel construction of a condenser, distiller, and feed-water heater wherein l have made provision for causing the entire volume of the entering steam to come into immediate .and intimate contact with the condensing-surface to a greater extent than heretofore by the provision of a novel construction of kbaffle-plates or diaphragme which are apertured and assembled in a novel manner and provided with means for causing the steam to travel in close proximity to the cold-water tubes, said steam being forced to proceed in its passage from its entrance to its exit in intimate contact with the cold tubes through which .the cool condeneation water is passing, whereby the steam is quickly condensed. l

My invention further consists in the provision of novel means for enabling the baiileplatee or diaphragme which are employed to be readily removed from the incloeing shell or casing and to be effectively held in proper relative position to the cold-water tubes.

l am aware that it has heretofore been proposed in the patent to Hand, No. 596,874, dated January 4, 1888, to employ a series of tubes and tube-platee so arranged as to be detachable from the casing, thereby forming a removable tube structure with deiiectingplates carried by the removable tube structure; but my invention differs from the aforesaid patent in the fact that l employ a different arrangement of baffle-platee or diaphragme and support the same in proximity to the water-tubes in a different manner, whereby l obtain novel and advantageous results which are not disclosed in the patent aforesaid.

lit is obvious that the principal instrumentalities of which my invention consists can be variously arranged and organized, and in the accompanying drawings lf have shown. onel simple embodiment thereof which l have found in practice to be successful, although it is understood that my invention is not limited to this specific arrangement and organization of these instrumentalities.

To the above ende my invention consists, broadly, of a new and useful condenser, dietiller, and feed-water heater wherein the whole volume of the incoming steamie caused to come into immediate contact with the condensing-surface, provision being made for bringing said steam into immediate and intimate contact with the cold tubes through which the cold condensation-water ie pa seing,-

whereby the steam is quickly condensed, and l further make provislon for enabling the various parte of the apparatus to\ be quickly accessible for the purpose of inspection and repairs.

It further consists of other novel features of construction, all as will be hereinafter fully set forth. i

Figure 1 represents a vertical sectional view, partly in elevation, of a condenser, distiller, and feed-water heater embodying my invention. Fig. 2 represents a section on line w Fig. 1. Fig. 3 represents another embodiment of a part of my invention where; in ll employ an auxiliary tube in the diaphragm-plate, whereby an elongated annular space for the passage of the steam is provided between the condensing-tubes and the outer or guide tube.

Similar numerals of reference indicate corresponding parte in the figures.

Referring first to Figs. 1 and 2, 1 designates the outer casing or shell of my novel distiller, condenser, or feed-Water heater, having the steam-inlet 2 and the steam-outlet 3, 1t being understood that said shell may lie in either a horizont-al, vertical, or other position.

4 designates the inlet for the'cooling-watei, which passes thence into the chamber 15, formed between the inlet-cap 5 and the adj acent diaphragm 7, the cooling-water passing from sald chamber 15 through the tubes 8 into the chamber 16, formed between the cap 17 and the tube-sheet 6, said cap 17 having the outlet 18 therein.

9 designates the diaphragme, which lf have shown in Fig. 1 as being three in number, although it is evident thatl their number may IOC? be increased or diminished according' to re- 1 ofthe caps and the plate contiguous thereto quirements, said diaphragms extending across the diameter of the shell and completely illing or closing it, except for the annular ports or assages 10, formed between said tubes ani diaphrag'ms, said passages forming a communication between the different steamcompartments 19, 20, 21, and 22, it being apparent that said compartments may be increased or diminished according to requirements, the lower compartment in the present instance being formed between the lower diaphragm 9 and the lower tube sheet or plate 7.- The diaphragme areheld` in roper position within the shell by the bots 11, which pass through their outer portions and also through the spacing devices or sleeves and immediate contact with thesame.

12, whose ends abut against the diaphragms 9, as will be understood from F ig. 1, said diaphragms, sleeves, and bolts being held in assembled position by the nuts 13, which when tightened will lock the diaphragms in position with respect; to each other'.

23 designatesy a bolt, which may be ernployed for tying or bracing the tube-plates 6 and 7. l

It will be evident that as the steam passes into the inlet 2 it will enter the hrst steamcompartment 19, completely filling the same, so that each of the tubes 8 will be completely surrounded and the steam will be in intimate The steam from the first compartment 19 will pass through the annular ports or passages 10 into the next steam-compartment 2() and will fill the same, and so on through each compartment in its passage through the apparatus and will finally discharge at the outet 3. By this provision it will be seen that the steam is forced totravel in its passage from the entrance to the exit through the annular passages 10 around the tubes in intimate contact with the cold tubes, through which the cool condensation-water is assing, the effect being that the steam is quicllily and positively condensed. In the construction shown in Fig. 3 I have shown guide-tubes 24, which are located in the diaphragme around the tubes 8, the space between the inside of the larger or guide tubes 24 and the outside of the coacting condensing-tube forming elongated annular passages 25, said guidetubes thus forming the communication between the several steam-chambers, it being evident that by reason of this construction the steam is kept longer in contact with the cold tubes, since the elongated annular passa es 25 cause the steam to travel `for a consi erable period in-close and intimate contact with the water-tubes 8, whereby the de-I sired result is obtained.

It will be seen from the foregoing that the diaphragms 9 are not permanently attached to the shell 1, but are connected to each other in such a way that upon the removal of either 1 the diaphragms and their adjuncts can be readily withdrawn for inspection or repairs.

It will be evident that various changes may be made by those skilled in the art which may come within the scope of my invention, and I do not, therefore, desire to be limited in every instance to the exact construction herein shown and described..

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a condenser, distiller or feed-Water heater, an outer shell, an inlet and outlet therein for the steam, water-tubes secured within said shell and a plurality of diaphragms secured within said shell, thereby forming a plurality of steam-compartments, each of said diaphragms having ports therein through which said water-tubes pass, of greater diameter than said tubes, whereby said steam in its travel through the compartments of said shell comes into intimate contact with said tubes.
