Letters Patent No. 102,272, dated April 26, 1870; antedated i'lctober 26, 1889.

STEAM-CONDENSER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it mayconcern:

Be it known that I, THOMAS L. J ONES, of Natchez, in the county of Adams and State of Mississippi, have invented a new and improved J et-Condcnser for Steam-Engines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawings making a part of this specification, in which- Figure 1 is a longitudinal vertical section, and

Figure 2 is a-transvcrse section of the plane face o the separator.

.lhis invention consists in providing the pipe through which cold wat-er enters the condenser' of a steam-en-- gine with a bell-shaped mouth, and in placing within said mouth ahemispherieal separat-or, so located that it may separate the column ofcondensing-water so that it shall pass into 'the condensing-cliarnher' in an expanded and tubular form, and thereby producea more enlarged effect upon the exhaust steam.

The invention also consists in making the hernispherical separator 'that is situated within. the bellshapcd riozzle ot' the water-'pipe with an internal chamber, and connecting said separator, or forming it in one piece, with a pipe opening into said chamber, and conducting into it live steam from the boiler, 'and making in the plane face ofthe hcmispherical separator a number ot holes, through which the live steam may be' discharged into the condensing-chamber in a comminuted form, which may be more readily con-4 densed, and thus assist in the perpetnation of the necessary vacuum. In the drawings'- A is the trumpet-shaped condensing-chamber, preferablyplaced in ayertical position for the better distribution of t-he condens'ug water and the advantage to be derived from its weight in descending, having a globular head, A', into which open passages, A" A", for the entrance ofthe exhaust steam.

Through the flattened top of the globular head passes a vertical pipe, B, for the passage of the condensing water, said pipe having its lower end, b, fiaring or bell-shaped. 'The water-pipe may have two ports of supply, one for a river or other ordinary source, and the other for a circulating pump, the latter t0 be used in case the amount 0i' water furnished from thc ordinary source proves insuicient by reason of the fineness ot' the pressure of the exhaust steam, or the too great length of the intervals between each exhaust.

Vithin the pipe B is a second and smaller pipo, G, which conducts live steam from the boiler, when tha-t may be necessary to `the increase of the vacuum, said pipe O passing through a. stuffing-box in the upper end ot' the pipe B, and terminating in a hemispherical base, C', which I call a separator, for the reason that it is so placed within the flaring mouth of the pipe l as to separate the column of water flowing therein and cause it to enter the condensing-chamber in a tubular and expanded form, greatly superior in its condensing power' to a solid jet ofthe saine amount of water, such as it would oth crwise be. y

The lower side of the separator Olis plane, and through it are made a sufficient nnmbcrof holes, c', opening into the chamber O" within the separator.. Ihe live steam passes into the chamber O" and out through the holes c into the space surrounded bythe tubular sheet oi' water-pouring oif from the separator', within which space it is condensed and a better vacuum formed, which tends to draw the exhaust steam onthe outside of the tubular sheet of water, through the same, and thus greatly to facilitate the condensation ot' the exhaust. lhe holes c are made upon the same principle as the hcmisphcrieal separator-that is, in order to bring the live steam into a more rarc and dit'- fused condition, and one, consequently, more favorable to its condensation than asingle large jct.

A solid spindle, 1'), projects from thc center of the face of the separator, and rnovcs in a bracket anywhere conveniently placed., to guide it.

The steam-pipe C has a sufficient play in the stning-box to enable the hcmispherical separator to be so brought in contact with the inside ofthe flaring mouth b as to close the saine, and measure the amount of condensing water required to eect thc necessary vacuum, and shut otl the water entirely, when desired;

Above the stuffing-box an arm, c', is attached to the steam-pipe, or in any convenient place, through the outer end of which arm passes a threaded bolt, d, projecting upward from one 'of the water-ports, on which threaded bolt are placed two nuts, tl d', one on eac-h side of the arm c', by means ot' which said arm may be fixed at any point' to which it is desired to regulate the amount ot' water required.

Y l ain aware that it is no new thing to effect the distribution of the condensing water into a tubular sheet; but what I have done is to effect such distribution by nieans ot' the bell-shaped mouth of `the water-pipe B and the enlarged head ofthe live steam'- pipe C placed therein. It is true that the same attenuation could bc' given to thc tubular sheet by ernploying a. water-pipe and a live-stearnpipc of the samev diameter' throughout as the heli-shaped mouth and the. enlarged head, but .the employment of this size of pipe would he entirely unnecessary for any other purpose than that of attenuat-ing the sheet. For all other purposes very much smaller pipes are amply sufficient. Hence, by enlarging the month of the water-pipe and the head of the steam-pipe, I aeeom- 2. Providing the hemisphericai separator with the plish the desired ob ject in a. less expensive manner chamber C", into which live steam is admitted at one than would otherwise be necessary.

, side, and with the perforations c in its plane face, for

Having.,r thus described my invention,

' Wiiatl claim as new, and desire to secure by Letters Patent, is-

1. The combination of the fnnne1-shaped mouth of the water-pipe B and the hemispherical separator C,

in lthe manner described and for the purpose. set forth.

the purpose specified.
