CQNVEYING DEVICE.

Application led April 7, 1926, Serial No. 100,470, and in Germany 'May 11, 1925.

My invention relates broadly'to a device l ate material is deposited direct to a storage place by means of a `single substantially straight guiding pipe thereby avoiding the usualdistributing and collecting pipings with undesirable bends, which are subjected to heavy wearing and cause a loss of pressure.

Not only does the single pipe convey the mixture of agglomerate material with .the water as a suspension iiuid from any given hopper to the storage place but this single pipe also conveys the water under-pressure from the source ofA power to the` hopper being emptied.

To accomplish the above I provide indi- Vidual ejector nozzles at the several depositing places in the pipe line. The insertion of these nozzles is made by an arrangement of an expansion mechanism ca'pable of loosening the pipe line Vflanges between which lies a slide carrying the. ejector nozzle. The flanges are brought together again for tightly locking the ejector nozzle in position.

In order that the invention may be clearly understood, I shall proceed to describe the same with vreference to the example of a ,preferred construction shown in the accom- .panying drawing, wherein:

Fig. 1 is a side elevationin vertical cross section taken on line 1 1 of Figure 3;

Fig.'2 is anl end elevation taken in cross section along the line 2-2 of Fig. 1;

Fig. 3 is a plan view, being a horizontal cross-section taken along line 3 3 of Fig. 1; and

Fig. 4 is a sketch in out-line showing a. side elevation of a plurality of the units of Fig. 1 assembled in place in an agglomerate disposal system comprising the single pipe above mentioned.

Referring to the drawings, the ejector slide 10 comprises two portions and in one portion there is located the nozzle 1, the ag- -glomerate intake 2, and the diffusion chamber 3. The diffusion chamber is-neeessary when the agglomerate is to be conveyed to great heights and for long distances. The other portion of the ejector slide 10 consists ofv the open passage 4. -The movement-for shifting the slide so that either portion of the slide is in operative position can be effected for example by means of a spindle 9, which as shown in Fig. 2 is screw threaded and held against rotation. engagingthcse threads is held against end movement by a support not shown, therefore the rotation of the handwheel will move the shaft 9 endways and, along with it, the slide device 10.

lVith the aid of the expansion mechanism 6, which is screw actuated, the flange 5 is loosened when the slide device 10 is to be moved and tightened again after the slide has been shifted. Reference characters 7 and 8 indicate elastic gaskets for insuring a tight joint at opposite ends of the slide when thc expansion mechanism is tightened.

In Fig. Llof the drawingI have designated with reference characters C1, C2 and C the several depositing places, such as the ashhoppers of a battery of boilers. A conducting pipe for water under pressure is designated as 17 the inlet of which is P; E1, E2

The h and wheel and Enare the ejector slide-devices, and D is the outlet end of Athe conveying pipe lo- `cated adjacent to the storage place;

The slide E2 may be readily moved into the operative position by means of the hand screw or spindle 9, the slide moving in guides provided by the interconnecting bars 15, which bars interconnect the end plates 12 and 14. The end plate 12 has an aperture to Conform with the cross-section ot' the pipe line 17. The end plate 12 and flange 5 are spread or expanded by actuation of the screw mechanism 6 for loosening the gaskets 7 and 8 from the ends of the slide, enabling the slide to be shifted sidewise. After shifting, by reversing the movement of thtl screw mechanism 6, the end plate 12 and flange 5 are brought together for gripping the ends of the slide in the newly selected position. A crank, not shown, is attached to the squared end of the spindle 16 for driving worm 11 and rotating screw mechanism 6 for spreading or expanding the end plate 12 and flange 5. There is sufficient elasticity inherent in the pipeline to permit slight longitudinal contraction and expansjon for ena-bling the slide to be shifted in position and. also a tight joint is insured between the This .to engage threads 19. The opening within the sleeve 6 is about the size ofthe opening in pla-te 12 yand fits around a very shortpiece of' pipe 20, loose enough to rotate freely. piece of pipe 20 has rigidly attached thereto a flange 21 at one end and a flange 5 at the other end. End plate 14 is kept from having axial or longitudinal motion.

relative to end plate l2 by means of the four heavy interconnecting bars 15. The rotation of sleeve 6 with threads 19 inside of stationaryend plate lLl-will produce axial motion that the pureewatercoming from the pump orl source of power not shown would meet no" obstruction as it passes under the hoppers C on its Way to the hopper C'. The slide device E2 under thevhopper C2 is positioned Yjust the opposite-to that of all the other lslides, so that the pipe 17 is deliberately obstructed'by the nozzle 1 so that the entire volume of water entering at the end P is iorced through the opening in said nozzle 1. The more or less gentle flow' in pipe 17 is forced fr m the nozzle with great velocity thereby teaing apart bit by bit the mass f agglomerate which .descends through the opening or agglomerate inlet 2 which is carriedby the nozzle side of the slide device.

A thorough mixing of the agglomerate with the water ensues so that a suspension is obtained that will readily flow through' outlet end D withoutclogging.

This use of the conveyor pipe to transmit the waterl pressure to the nozzle adjacent that particular hopper. being emptied has in sleeve 6 toward or from end plate 12 andi tHe advantage 0f avoiding amultiplicity of this end motion of sleeve 6 will be trans-- mitted byv means of flanges 21 and 5 and '20 so as to move 'flange 5 toward or away from end plate 12, thus 'tightening or loosening the slide device 10 ield between 12 and 5. Worxn whe'ef 18 has side motion with respect to worm 11 but the amount of such motion is so slight that the teeth of wheel 18 would never come anywhere near escaping from the s worm 11. Also, the end motion 1m arted to pipe 17 as a' result oiits being bo tedto flange 21 is soslight as to cause no more difficulty than expansion and contraction due to heat and col-d.

The diffusion chamber 3 narrows the passageway in front of the nozzle so that the particlesy of agglomerate can be actually jet may This, ofv course, 'aids in the mixing and hence in the formationv cfa good suspension.' The liner or diffusi on chamber 3 also protects the main casting forming the ejector slide 10 against undue wear at a point wherev the agitation of the agglomerate particles is at a maxi- The operation of the conveying device is as follows:

The slide E1 under hopper C1 would be'moved tobring tubular portion 4 in exact alignment with the pipe 17. Thus, the. suspension ofagwater coming from Cz-fEz could pass underneath C1 without hindrance. The slideEu under the plurality of hoppers C would likewise be positioned with 4their with the lpipe17 so iral on illustrative purposes,

pipes as is the case where piping separate from the conveyonpipe is used to transmit the power transmitting pressure fluid to nozzles adjacent the agglomerate intakes.

' Any attempt to, use pipe without theinsert-ion of a jet 'at the point`where agglomerate is being drawn in may result in a complete failure to draw in or may result in clogging.

It should be especially noted that the substitution of what is in effect a short length of pipe, namely, tube`4, for-the nozzle and Aagglomerate inlet results in the restoration of the pipe to normal contour at points opposite hoppers not being emptied and results .in a complete avoidance of pockets andfeddy currents as would be the case if a common ate valve were used in the 'constricted neck at' the bottom'of the hopper. Also, the use of the cross sliding ejector piece v10, enables.l the nozzle 1 to be completely removed froml the 4pipef17 without the presence of sideockets either during its use in or absence rom the pipe. y
