IMPROVEMENT IN EJ ECTORS.

The Schedule referred `to in theseLettex-s Patent and making part of the same.

.the peculiar manner fully described hereafter, so that it can be readily adjusted to raise and force water; or

Ito raise a large volume of water without forcing the same; or to raise a moderate volume of water, and force itto a limited height, as circumstances may re- Figures l and 2 in the accompanying drawing illustrate the instrument, with the movable parts in different posit-ions.

r'eneral Description.

A is the exterior casing of the instrument, terminating at one end in a branch, a, to which the discharge-pipe can be secured, and at the opposite end in a tubular projection, b, having internal screw-threads adapted to external threads on a nozzle, B, which projects into the casing A, and is reduced in diameter at 2;, where it forms a valve, adapted to. aI seat on the edge of an opening in a partition, f, in the casing A.

'I he nozzle B has any desired number of holes, It, and can he so adjusted that these holes shall-connnunicate with the suction-branch 'i of the casing A, as

shown in tig. l, or cut ott from such communication,

as shown in iig. 2.

Dis an inner nozzle, conmmnicating with a steampipe, and having a screw-thread adapted to an internal thread in the head of the nozzle B, so that it can be adjusted until its end 'mf is in contact with the in'- terior of the nozzle B, where the latter is reduced in diameter.

As seen in tig. l, the instrument is adjusted for raising and forcing water, the opening in the partition f being closed, so that the water must pass from the suction-branch t throughl the openings l1, and forced thence, by and with the steam, through the end e ot' the nozzle, and through thc branch a.

When the instrument is required for simply raising water without forcing it, the nozzles are adjusted to the position shown in fig'. 2, thereby closing the openings h, exposing an annular opening, n, in the partition j, and causing the end of the vnozzle D to be in contact with the interior of the nozzle B, where thc latter is reduced in diameter. The water, in this case, must pass from the suction-branch t' directly through the annular'opening n in the partition f, and thence with the jet ot' steam i'om the nozzle D-througli the branch a..

A much larger volume of water can he raised and simply delivered at the discharge-branch a' by the instrument when in thecondition shown in fig. 2 than when it has been adjusted to both raise and force the water, as shown in tig. 1.

` The nozzles may he so adjusted that the openings h. are partly expo'seth'the end of the nozzle m a short.

distance i'om its seat in the nozzle B, and the latter so adjusted as to permit a limited opening in the partitionf, in which case a comparatively large volume of water may he forced to a limited height through the branch a.

It will now be seen, without further description, that the instrument may be readily adjusted to raise water and force the sa-me; or so adjusted as to raise a large volume of water and simply deliver it without forcing; or to raise a moderate supply of water and force it to a limited height, as the duty to he performed may require.

Both nozzles are furnished with tightening-nuts, so that they can he secured after adjustment.

Claim.

lhe exterior casing A, its branches a b e', partition f, and valve-seat, iircombination with the adjustable nozzle B, adapted to the valve-seat, and having perforations It h, and steam-nozzle I) adjustable in the nozzle B, all substantially as and for the purpose described. j

In testimony whereof, I have signed my name to 'this specifica-tion in the presence ot' two subscribing witnesses.
