Leners Patent N 107,603, (zaad samba 20, 1870.

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

invention.

`Figure' 2 isa transverse section of the same, taken in the plane indicated by the line x x, tig. 1.

Figui-e3 is asimilar section, the line y y, iig. v1,inr dicatingthe plane of section.

ASimilar letters indicate corresponding parts.

This invention relates to a nozzle of that class which. is used for the purpose of producing arvacuum in a furnace, cupola,`converter, or other apparatus of a similar nature, or in the ascension-pipe ot' a pump, or in any apparatus wherethe air is to be exhausted' or rarefied.

The improvement consists in making the nozzle with a gradually-increasing cross-section from its narrowest point toward the discharging end, the orifice of the nozzle presenting two or more dat branches, in such a manner that the jet of steam, while passing through the nozzle, is allowed to expand, and brought in that form which presents the greatest possible surface of contact with the airas compared with the volume of steam which discharges from the nozzle, and, thereby, the useful eect of the nozzle is materially increased.

In the drawing- The-letter A represents a nozzle, which is provided at its receiving end with a screw-thread, a, so that it can be conveniently secured to a pipe connecting 'with a suitable steam-generator.

' Said receiving end is bell-mouthed and. circular, but

the .area of vthe transverse 4section of the nozzle changes gradually into a cross, and itincreases toward the discharging end, as shown in the drawing, so that the transverse section of the nozzle, near its discharging' end, is such, as shown in fig. 2.

By thesemeans the jet ot' steam discharging from the nozzle presents a very large surface of contact with the surrounding air, as compared with the volumeof said jet, and the 'effect of the nozzle 4is greatly improved.

f It must be remarked that this object can, also, be obtained, but less perfect, by giving to the discharge opening the shape of a simple dat channel, or, iii other words, by making the same only with two branches, b bf, instead of with four, as shown in the drawing, or

the number of these branches may be three or live,- -or any desired number, although my experiments show that a nozzlewith four branches gives the best effect.

It' desired this nozzle ,may be used with a core in thc usual manner for regulating the area of the receiving opening, this opening being'left round for this pur-l pose;

What I claim as new, and desire to secure by Letters Patent, sv 1. A steam-nozzle, the discharging end -of which presen ts two or more flat branches, yb b', substantially as shown and described.

2. A steam-nozzle, having aclrcularreceiving end,

and a discharging end, with'two or more at branches, v

b b', and the area of whichA gradually increases from its narrowest part toward the discharging end, substautially as set forth.
