. :0 ALL WHOM IT MAY ooncnnm Be it known vthut we, I, SHIELDS WILSON and Homes Sun, of Philudelp'hin, in the county of Philadelphia, and Stute of Pennsylvania," have invented a new and useful Improvement in Surface-Condensers; and we do hereby declare thejfollowing to be a full, clear, and exact description oi the some, referenceheing had to the annexed drawing. and {0 thelettcrsof reference marked thcreo'n,-

Tho piture'of ou r invention consists, first, in remo'vingtho condensed steam nftcr'it has passed through a surface-condenser, and disch srging it directly into the boiler by the feed-pump when arranged in connection itith the air-pump, for removing the air, vapor, and surplus water second, in theparticnlnr arrangement ofthe --'ol'r and circulating-pump and feed-pump, in respect to the surfuce-condcnser, for carrying out our improvement.

in order to enable others to make anduso our invention, we will'now proceed .to describe its construction and operation.

On reference to tho annexed drawingwhich forms-port of this specification- Figure lie at side view, with the condenser in section through 1-2, fig. 3, and the air and circulating-pump, I with 5- portion of: the piping removed.

- Figure 2 is a side view in section through 3-4, fig. 3. 4

"Figure '3' is an end view in section, through 5-6, 1, io'okmg' in the direction of the mow-1. t

Figure .4is an end view, looking in the direction of the arrow 2.

Figure 5 is a. plan in section, through 7-8, fig. 1, looking in the direction of the arr-0W8.

Figure 6 is a plan of the condenser, in section through 9-10, fig. 3, looking in the direction of the arrow 4.

Figure 7 is an enlarged view of e andf, as in fig. 3.

Our improvement is shown applied "to a vertical direct-acting propeller-engine.

Ais a he'd-plate, provided with suitable bearings toreeeive the crhnk-axloB. G and C are housings, erected on one end ofA, which are provided with guides, a and a, for tho cross-head D. On the outside of C and C, at a height suflicient to get intho' pumps, is fastened the surface-condenser E. b is a passage for the exhaust-steam, e the tubes, d a box .fo'r the condensed steam and vapors, e'a .reservoir for supplying the feedpump, andfa passage above the level of e for leading the vapor and surplus water to the air-pump. n is an 7 opening, for receiving the refrigerating-water from the pump, andu an opening at the top, leading into the 4 passage v, nhich discharges into the heir K, havingta nozzle for a discharge outboard.

The cross-head D is connected to the crank-axle B by the rod F. 9 end h are horns on D, for working-the air and circulating-pump and feed-pump. G is the steam-cylinder, securedto theitop of C and G, and further secured by'the columns Land L to A; 4 For clcarnes's, the valve-gear has not been shown. H is the piston, with its rods j and j secured to the cross-head D. k is a pipe, for conveying theexhaust-steam from the cylinder G to the condenser E. I is the air and circulating-pump, the upper end of which is used as the circulating or refrigerating, and the lower as the air-pumps l is the receiving and discharge-valve box of the. circulatingpump, by the flange of which the pump is secured to the condenser E. m is the receiving-nozzle. ois the piston and 12 its rod, secured to the horn g of D. .q is the receiving and dischargewulve box of the air-pump. r is the supply-pipe attached to f, and s is the discharge-pipe, attached to K, a valve, w,boing placed at the bottom of K. J is. the feed-pump forsupplying the boilers, and is secured to 0. his theplunger, secured to the horn h of D. yis the receiving and discharge-valve box. z is the receiving-pipe, with attachments to e, K, and a. t is the discharge-nozzle. r

A The engine being in motion, tlie operation will be as follows: The circulating end of the pump I, receiving its ivater at m, discharges through 1t into the condenser E, around the tubes 0 c, out through u into 1:, andfrom th'enco into and out through R, Theexhaust-steam, leaving the cylinder by the pipe k, enters b and passes through the tubes 0 c, -vvhere it is'c olnde'nscd. The products of condensation pass into a, the water collectingin v e, and the surplus water and vnporilowing into f. The feed-pump J takes its supply from c through 2. In case of shortness of supply, orderangement, \vatercen be .taken from the box K, orjfro'm the discharge-pipe s of the uir-pump- The discharge isthrought into the boiler. The surplus water and vapor are drawn oil atf through the pipe 9 intolthe oir-pumpend of I, and forced out through 3 into K, the return beiiig checlced by the valve 20. 1

It has been customary heretofore to tnlce out 'nll'the products of condensn't-ion with the: air-pump, and to drmv the feed-water from its discharge. Now we wish to dispense with this double woflgond, to oecouiplishit,

toke our feed-wnlter-direct from the condenser; and, in'order-to collects. snfiicient supply, ire employ a. reser-- mix", or what becomes such-by the air-pump supply being taken off at a. higher level th'nn that of the feed-pump,

a'nd'which we prefer plocing beloiv the lower row of tubes, so that the entire surfuco'o f the latter may be 'eflicient for condensation. By this mode the oir-pump has only to take out, the surplus water and vapor; It

will be observed that by this operution the air and circulating-pump can lie-"combined in one without any or the evils attending from leakage of piston. The two pumps may also be separate. v

Now, we do not confine our improvement to. the purticulorplan of condenser shown. In applying'it to the vertical tubular condenser, the lower part of the box below the tubes should be used as the reservoir, and the air-puuip supply taken out at a. higher level in the some.

1. We know that air-pumps have been discarded, and that the feed-pump has been used to take out all the products of condensation; but this plan is objectionable, becuuse tl|e pump huving to be madelurger than when it is used merely to act as a feed-pump, so thot it will drain the condenser under all conditions, will consequentlj places greater load on the engine when the pump is acting ugainst the boiler-pressure.

We also know that connection with the feed-puin'p hos been made ntthe lower, end of the tubes. and with th s air-pump at' the upper-end of the some. Now, this ni'rangement'hos'serious disadvantages: first, the passage of the steam into and through the tubes is impeded by the descent of the heuvy products of condensation;

second, iii case the engine had been standing, the tubes would become so filled with water that upon r-estartingall aceessof steam to the tubes would be cut off, and the water could-only be removed by the feed-pump, tho air-pump not being in a position to nssist. In our srrnngement the steam and products of condensation move together, and the entire product cmptiesinto what we term the fresh-water side of the condenser. Also, both pumps are so situated as to take their water before the some reaches thc tubes.

Now,'wo' do not therefore claim broadly the feed-pump, taking its supply direct from the condenser, or at I a, lower level thou the air-pump, but 4 We do claimv. l I 1. Removing the condensed steam, after it has passed through o'surface-con'denser, and discharging it directly into the boiler by the feed-pump, when arranged, in connection with the air-pump, in the m'a-nner and for the purpose set forth.

2. The pumps I and J, when arranged in respeet'to the surface-condnserE, substantially as described and for the purpose set forth.

In testimony whereof, we have signed our numes to this specification in the presence-0f two subscribing witnesses. t 4
