Application filed August 4, 1884. (Model.)

To aZZ whom, it may concern:

Be it known that I, JOHN H. BOOK, a citizen-of the United States, and a resident of J onesborough, in the county of Grant and State of Indiana, have invented certain new and useful Improvements in Injectors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to injectors; and it has for its object to produce a device of this class which shall be serviceable for raising water from deep wells and injecting it into steam-boilers.

Nith this end in view, and with the further object of providing a device which shall possess superior advantages in point of simplicity, durability, and general. efiiciency, my invention consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In its complete form, or when it is to be used for raising water from deep wells, my improved injector consists of three principal parts or sections, which may be designated, respectively, as the top, the middle, and the bottom sections. I would, however, have it understood at the outset that when desired or necessitated by the depth of the well from which the water is to be raised two or more of the middle sections may be used; also, that the middle and bottom sec tions may be dispensed with when the water is to be raised to a height not exceeding about twenty-five feet, or the height to which it may be raised by injectors of ordinary construction.

In the drawings hereto annexed, Figure 1 is a vertical sectional View of the top section of my improved injector with a portion of the connecting-pipes. Fig. 2 is a vertical sectional view of the middle section of the in jector. Fig. 3 is a vertical sectional view of the bottom section, and Figs. 4, 5, 6, and 7 are detail sectional views, on a larger scale, of several parts of the injector. Fig. 8 is a vertical sectional view of my improved injector, showing the sections composing the same connected and in their relative position for operation; and Fig. 9 is a horizontal sectional view taken on the line .00 m in Fi 1 of is cored out so as to form a water-chamber, 13, k

and branches 0, D, and E, which latter forms an overflow provided with a stop-cock, which is not shown in the drawings. An additional downwardlyextending branch, F, forms a secondary water chamber or passage, from which a nozzle, G, extends upward into the water-chamber, nearly to the top of'the same, or of the branch D, which forms an upward extension thereof. The branch D is screwthreaded exteriorly, and its upper end is ground so as to form a seat for the steam-cap H, the lower end of which is provided with an annular flange, I, to guide it to its seat, an annular connecting flange, l and a downwardly extending nipple, J, extending slightly into the upper end of the nozzle G. The steam-cap is secured to the branch D of the casting A by a union-nut, K, taking over the flange 1 as shown in Fig. 1 of the drawings. The steam-cap is constructed with a shoulder, L, and with an upwardly-extending tubular stem, M, formed with a valve-seat, N, above which it is interiorly screw-threaded for a portion of its length to receive a spindle, 0, having a valve, 1, from which a point, Q, extends downward into the nipple. The upper end of the stem or spindle Ois provided with a handle, R, by means of which it may be conveniently manipulated.

S designates the steam-ch.est, which consists of a casting which is cored so as to form a chamber, T, mounted upon and surrounding the stem of the steam-cap, on the shoulder L of which the steam-chest rests, and provided with branches U and V, the former of which is connected by a suitable pipe with the steamspace of the boiler. When the device is in operation, steam is admit-ted to the steam-cap from the pipe or passage V, through an open- Ais a casting having four arms or branches,

B, G, D, and E, and cored, so as to form passages, F, connecting the branches B and O, and G, connecting the branches D and E.

The passage has a nipple, H, opening into the branch E of the passage G, The outer end of the branch 0 is interiorly threaded and provided with a plug, 1. The opposite passage, E, is also interiorly threaded and provided with a plug, J, having a longitudinal double-tapering perforation, K, the inner end of which registers with the nipple H, and the outer end of which enters the branch G of the casting A, with which it is connected by means of a union-nut, L, taking over a flange, M, upon the said plug. The upper branch, B, of the casting A is connected with the branch U of the steam-chest by means of a T-"coupling, N, one of the lateral arms of which has a steam-pipe, O, and the lower branch, D, of the casting A has a downwardly-extending water-pipe, 1?.

Q is a casting which constitutes a portion of the middle section of the apparatus. This casting, which may be designated as a steamchest, is provided. with upwardly and downwardly extending branches R and S, the former of which is connected with the steampipe 0, and the latter of which has a downward continuation, T, of the said steam-pipe. The casting Q has a transverse seat, U, for a steam-cap, V, the outer end of which is threaded, so as to receive a closed nut, XV, whereby it is kept in position in its seat, and the inner end of which is provided with a flange, X, and a collar, Y, serving to guide it to its seat.

Z is a globular casting, which is. cored so as to form a water-chamber, A and branches B, O, and D", the former of which, B", forms -'a seat for the steam-cap V, which is secured thereto by a union-nut, E taking over the flange X of the said steam-cap. The latter is provided with a nipple, F registering with a nozzle, G formed laterally in the casting Z,

and opening into the branch 0 of the same. The said branch G is suitably coupled or connected with the water-pipe P, and the branch D has a downward continuation, H of the said water-pipe. The steam-cap Vhas a series of openings forming a strainer, as at 1 facing i the branchR of the casting Q, and the latter is formed with a globular recess or chamber.

J", surrounding the stem or shank of the said steam-cap, so as to admit of the passage of steam around the same and into the branch S,

The branch S of the casting Q is provided with the downwardlyextending steam-pipe T, and the branch D of the casting Z has the downwardly-extending water-pipe H The latter is connected by a T- coupling, M, with the lower branch, N of a casting, 0 which is cored so as to form a water-chamber, P having an upwardly extendin g nozzle, Q", registering with a nipple, R extending downwardly from a cap, S, seated upon the upwardly-extending branch T of the casting O and connected therewith by a union-nut, U and the upper end of which cap S is coupled or connected with the steam-pipe T. The casting O has a lateral branch, V from which a water-pipe, W", extends downward into the well, and the lower branch, N of the T- coupling M is provided with a downwardlyextending overflow-pipe, X which is preferably extended below the level of the water in the well, in order to prevent the sediment of the latter from being disturbed by the overflow water. The pipe X is provided with a stop-cock, Y having an operating-lever, Z from the ends of the arms of which operating cords or wires A A extend to within convenient reach of the operator at the top of the well.

The operation of this invention will be readily understood by those skilled in the art to which it appertains when reference is had to the foregoing description ,and to the drawings hereto annexed.

It has been already stated that when the device is to be utilized for raising water from deep wells and injecting the same into a steamboiler the entire apparatus herein described is to be utilized, with the provision that in very deep wells the middle section of the apparatus may be duplicated, or that as many of these sections may be used as may be found necessary, the number being governed by the depth of the well, and the several sections being connected by steam and water pipes.

The operation of the device when used in deep wells is as follows: The overflow-cock Y is opened and the steam-valve P is closed,

while a globe-valve (not shown in the drawings) is opened, so as to admit steam from the boiler into the chest or chamber T, from which a portion of the steam finds its way into the steam-cap H, while a portion of the steam passes around the said steam-cap and through the downwardly-extending steam-pipe of the same into the middle section, whence a portion of the steam escapes into the corresponding water-chamber, while the remainder of the steam passes down through the pipe T to the lowermost section the injector, and through the steam-nozzle of the said section, around which the water is thus caused to rise.

It isobvious that when the apparatus is applied to shallow wells the intermediate and the bottom castings or sections may be dis pensed with by an arrangement which is obvious to those skilled in the art, and which IIO SOS/06 3 may be briefly described as simply consisting in dispensing with the middle section or sections of the apparatus and making proper connections to correspond.

Havingthus described my inventioml claim and desire to secure by Letters Patent of the United States-- 1. A water-lift con'iprising a series of inj ectors arranged one above the other and provided each with a steam-cap and a surrounding steam-chest, from which the steam may pass to and operate or actuate the injector next below, substantially as and for the purpose herein set forth.

2. In an injector, the combinatiomwith the
