|ivllPRovelvnaNTl Specilication forming part of Letters Patent No.v 221,059, dated October 28, 1879; application filed May 18, 1878; patented in England, October 29, 1877.

To all whom it may concern Be it known that we, EDWARD HAMER and J AMES METGALFE, both of Aberystwyth, in the county of Cardigan, and EDWARD DAVLES, of Llandinannin the-county of Montgomery, in theKiugdom of Great Britain, have inventednew and useful Improvements in Apparat-us for Feeding Locomotive and other SteamBoil ers or Generators, called Injectors,77 for which we have obtained Letters Patent in Englandv bearing date the 29th of October, `1877, fand numbered 4,014, applicable also -for lraisin g and tbrcing'liquids for other purposes; andwe, the said EDWARD HAMER and JAMEs Mn'rcALnn and EDWARD DAVIEs, do hereby declare the nature of the said invention and in what manner the same is to be performed to be particularlydescribed'and ascertained in and by thefollow-in g statement thereof-that is to say:

This invention has reference to further improvements upon the apparatus and injector for which Letters Patent 'No.fll were granted to us iu England bearingdate 14th February, 1876 5 and it consists of an improved form of injector for feeding boilers or for raising` or forcing liquids.

The improvements in the injector consist in forming that part known as the combiningcone77 (wherein the steam an d water are brought into contact) in such a manner that `its area and capacity may be easily and rapidly increased or diminished forpfacility in starting. For this purpose we construct that portion of the piece inwhich the combining-cone is formed in two parts capable of sliding laterally toward and from each other in a direction transverse tothe axis of the cone, and so to increase orV diminish the area of the nozzle of the cone. Connected to the sliding part ofthe piece in which the combining-cone is formed is a lever actuated by a handle or hand-Wheel and screw or other suitable mechanism, so that the attendant may have it entirely under control, and so facilitate the starting ofthe injector.

When ready for starting the sliding part is drawn backward to give an increased free section to that part of the cone. The exl1auststeam and water are then admitted and pass through the combiningcone. As soon as this is effected the sliding part is forced forward by the lever, and forms a complete cone of the proper 'size for the continuous workin g ofthe injector with exhaust-steam.

In steam-engines providedwith injectors of this class we usually provide the exhaust or blast pipe with a perforated plate adapted to be rotated upon a second perforated plate, the

yperforations in both being arranged to :register with each other when in proper position,

.position of the openings being shown on Fig.

5. .Bis nutfor adjusting the spindle G-so as to regulate the size of the steam-opening through the steam-cone D. The position of this steam-cone can also be regulated by the' pinion E, Fig. 3, workin g into teeth on the ontside of the cone D. F is the outer casing, having at the top allange to receive the steam-pipe, and on one side the feed-water inlet Gr. Below this casing is the combining-cone, made in two parts, H and J. (Shown also in horizontal section, Fig. 4.) The part H isscrewed to the casing F, and is formed so as to receive the slide J.

In manufacturing that portion ofthe piece in which the combining-cone is formed, the two pieces II and J are rst carefully fitted to each other, and then, having been firmly secured, the combiningfcoue or chamber is bored by suitable boring-bits. The movable part J is actuated by the lever shown on Fig. 1, and is represented on Fig. 4 as drawn backward,

so as to leave an opening, the closed position being represented by dotted lines, and in Fig. 3 the part J 'is represented as closed,its drawnback position being represented by the dotted' lines.

At the lower part of the combining-cone is the overflow-opening K, and screwed into the lower end of the combining-cone is the discharge-cone L, with tlange for connectingit to feed-pipe of boiler.

It must be understood that the details of construction may be varied, the important feature being the construction ot' that portion in which the combining-cone is formed in separate parts capable ot' sliding laterally toward and from each other, and although in the arrangements We have shown in t'he drawings above referred to only one ol' the parts by which the combining-cone is Jformed is shown tobe movable, itwill be readily seen that two or more such parts could, in a similar manner, be made movable.

Another arrangement ot' our improved injector, constructed to allow of the admission of a further quantity ot' exhaust steam around the lower end ot' the combining-cone, is shown in the other ligures.

Fig. 6 is an elevation 5 Figs. 7 and S, vertical sections taken at right angles to each other, and Fig. t) is a horizontal section through the combining-cone.

In these views many of the parts are similar in construction and position to those al` ready described, the additional parts being the inlet M for the additional exhaust-steam, the

. circular chamber N, formed round the combining-cone, the split co11eQQ,made in two pieces and forming the extra combining-cone, and the screws l I), one of which is inserted in each halt` of the split conc. By this arrangement the body ot' steam and water passing Jfrom the combiningcone is superheated, and passes through the discharge-cone and into the boiler at an increased temperature.

Having now particularly described and ascertained the nature of our said invention and how the same may be carried into practical operation, we would have it understood that what we claim, and desire to secure by Letters Patent, is-

1. In an injector for steanrengines, a twopart combining cone, whereby the sectional area of the steam and Water passage of said cone maybe enlarged or contracted independently ofthe spindle. substantially as described.

2. rEhe two-part combining-cone, consisting of the stationary partH and the laterally-movable part J, in combination with the casing F and a hand-lever or equivalent device, substantiall y as described, tor the purpose set forth.

3. In an injector for steam-engines, the combination of a discharging-cone with a laterallyadjustable combinin g-cone, substantially as described, for the purpose specified.

4. In combination, the laterally-adjustable cone H J and the vertically-adjustable cone D, substantiallyas described, fertile purpose specicd.

5. In an injector for steam-engines, the vertically and independently adjustable stcam cone and spindle, the laterally-adjustable com biningcone, and the discharging-cone, all comA bined, constructed, and operating substantially as described, for thepnrpose specified.

6. In an injectortorsteam-engines, the combin ation of a vcrtcally-adjustable spindle, C, a vertically-adjustable steam-cone, I), a laterally-adjustable steam-cone, .I H, a dischargingcone, L, the steam-inlet A, water-branch Gr, andthe usual overflow-pipe, all combined, constructed, and operating substantially as dcscribed and shown.
