PULSOMETER.

SPECIFICATION forming partpof Letters Patent $0,703,788, dated July 1, 1902. Appunti@ tied Jimmy 13, 1902. serial No. 89.491. (No model.)

To all whom/ it may con/cern:VV

Beit known that I, PAUL HAUssMANN,1engi-' neer,a subject of the' German Emperor. residing at Burg, near Magdeburg, in the Empire of Germany, have invented certain'n'ew and useful Improvements" in and Relating to Pulsometers, of which the following is a specification.

This invention relates to vs team water-litters or pulsometers, and. more particularly to the construction of the injecting nozzles or devices which produce the condensation of the steam in the interior of the pulsometer-chambers. The said injecting nozzles or devices are so arranged as to render the injector-tube adjustable, while the mouth of such tube is adapted to act in conj unctionwith' a spraying device provided'in the interior ofthe said' chambers. With this arrangement it is possible to regulate the quantity'of the refrigerating-water to the existing conditions of working, (suction-head, head of pressure, steampressure, dac.) This is important for the economical use of the pulsometer,ginasmuch as the introduction of too smallquanties, as also unduly large quantities, of refrigerat-' ing-water unfavorably affects the; economical efticiency as well as the general working capacity of the pulsometer. The regulation can be effected during working from the'eX- terior. It is essential that the water-sprayer coacting with the adjustable mouth of the'injecting-tubein the interior of the chamber and the parts forcarrying it'should be outside the injector-pipe. The refrigeratingwater flows through the injector-pipe in a full jet until it reaches themouth, where the division of the Water-jet is effected. By this means it is impossible'for the injector-pipe to become choked by foreignsubstances, and thus cause an imperfect function of the' apparatus.

The device adapted to coact with the inj ector-pipe for spraying the water may advantageously be constructed in such a manner as to cause the vfull water-jet to spread in the form of a trumpet, and thereby effect an expeditious and energetic condensation of the steam. The supply of the injector-water is effected by connecting each injector-pipe by means of a flexible or yielding pipe with the opposite chamber or with another pressurechamber. i

" vThe Ainvention is shown in the annexed drawings in two formsof construction.

Figure l shows a front elevation, partly in section, of one form of pulsometer constructed in accordance with this invention. Fig. 2

,is a section taken on the line A B of Fig. l.

Fig. 3 is asection taken on the line C D of Fig. 2. Fig. 4 is a separate'view, drawn to a larger scale, of the'injecting device. Fig. 5 is a modified construction of the injector device. Y

The pulsometer is mainly of ordinary form. The two chambers ck, Fig. 2, are connected, by means of channels j, with the valve casing or chamber a, which latter comprises the suction-chambers m m', provided with suctionvalves cc ad, respectively, which correspond to the said chambers kk@ The valve casing .or chamber .c further comprises the pressure or :forcing chamber fn, with the pressurevalves y y. The steam is supplied through the pipe t, iitted with valve u. `The two injector, devices are shown at s and s in Figs. l and 2.

One of the two injector devices connected withthe pulsometer shown in Figs. l and 2 is shownon a largerscale in Fig. 4.

In `the injecting device,lFig. 4, the injectorpipe'ais adapted to be slidendwise for its entire length. For this purpose the said injector-pipe ct is carried: byV a membrane t', which forms a tight jointfor the tube a with regard to the injector-chamber. The membrane is rmly clamped-between the ange g and ring g2, which latter are together fixed imposition upon the pulsometer, as indicated in Fig. 1, so that the said'injector-pipe a eX- tends through the opening s2 into thevinterior of the chamber.

The means for adjusting the position of the injector-pipe a are as follows: The lower part of the injector-pipe ct rests upon a steel screw f, which is screwed into an arm orbow-piece g. Thus by screwing the set-screw f the injector-pipe c can be displaced in its longitudinal direction.

f The division of the injector-water is eected by the aid of a cone c, covering the mouth b of the injector-pipe a. This cone c is fixed to a carrying strap or bow Z, which may be suitably fixed to the part g. Itis important also that the parts which carry the cone c are outside of the injector-pipe a.

The injector-pipe a is conveniently provided with a lateral socket or tube connection, to which is attached the conduit for the pressure-water. The flow of the pressure-jet is indicated by the arrow in Fig. 4. In thearrangement shown in Figs. 1 and 2 the injector-pipe a of the chamber 7c is connected with the other chamber k by a flexible tube d. In the same manner the injector device of the chamber 7c may be connected, by means of a flexible conduit d', with the chamber 7c. In Figs. 1 and 2, however, the second injector-pipe a of the chamber 7o is connected by a flexible pipe d with the pressure-chamber n by connecting the pipe d to the tube connection 0i of the pressure-conduit 0. The injector-pipe is guided movably in the socket g3, arranged on the flange g. The tight joint is formed, as previously stated, by the clamping-membrane t', which latter forms in a certain manner the bottom of the chamber 7c or 7c and closes the space g4 from the exterior. The membrane is preferably made of metal, so that it is able to offer resistance enough against the greatest pressure in the chamber.

The action of the pulsometer is known. The two chambers 7c 7c' are alternately affected by the reversing-valve u, so as to be emptied by the steam-pressure and filled through the condensation of the steam, followed by the sucking action, .whereby the suction-Valves and w' and pressure-valves y fg' effect the delivery of the water in the known manner.

As soon as one of the chambers has been emptied andiilled with steam and after the valve fu, has reversed the action the injector device introduces the refrigerating-'waterinto such steam-filled chamber by the action of the pressure in the other chamber or the pressure existing in the chamber 'n or pressure-conduit o', so that an effective condensation and an energetic suction is produced through the injection. By the adjustment of the injector-pipe a upwardly or downwardly the quantity of injection-water may be increased or decreased.

In the modified arrangement of injector detoepas vice shown in Fig. 5 the pipe ct is movably guided in the plate v2 through a stuffing-box o o. The part o2 is secured in frontof the opening s2 in a similar manner, as previously described with reference to the platev or flange g', Fig. 1. The plate o2 is furnished with the strap or bow for the spraying-cone c and with an arm g for the set-screw f.

The details may be varied. The arrangement of the pulsometer may be so carried out that either both iiexible pipes d of the two injector devices are connected with the pressure-pipe o or with the chamber -n or that both iieXible pipes are connected like the pipe d with the corresponding chamber 7c or 7a', respectively. In the latter case the two pipes would cross one another. The injector device may be used in connection with various kinds of pumps or pulsometers. ing means for the injector-pipe may be of any convenient form or type. For example, the adjustment of the injector-pipe may be effected by revolving it or otherwise conveniently. The spraying means may be of any other form.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. A steam water-lifter, comprising a working chamber, a spraying device therein and an injector adjustable with relation to the spraying device.

2. In a steam water-lifter, a pressure-chamber, a working chamber, an injector-pipe eX- tended into the'working chamber, a spraying-cone above the pipe, and means for adj usting the pipe toward and from the cone.

3. In a steam water-lifter, two pressurechambers, two working chambers, injectorpipes leading into the working chambers, spraying-cones supported rigidly at the inner ends of the pipes and outside thereof, means for adjusting the pipes with relation to the cones, and iieXible tubes for connecting the injectors with chambers.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 20th day of December, 1901.
