To all whom it' moy concern: Be it known that l CARL FVeLLnn, a citizen of the Republic ot Switzerland, residing companying drawings, and to letters or tigures of reference marked thereon, whichl form a part of this specification.
rllhis invention relates to improvements. in spraying apparatus such as sand-blast-machines, white-washing and painting sprayers and the like and it is the obj ect ot the invention to provide means tor discharging the spraying material. tank and for cleaning the admission or teed member for the material to besprayed.
Whenever sand, paint or a chemical substance in thel `term oit grains or ot a thick liquid has to pass trom a tank through a passage having a comparatively narrow cross-section, there is the drawback that the passage may become clogged at its narrowest cross-section by impurities or 'by the termation ot lumps in the sand, paint or the like, due to atmospheric induences or other causes.' "Fo clear this it is necessary to dismantle certain parts of closing and regulating devices, ot which said admission member for the material terms a part, or to empty the tank, or even to perform both these operations. rllhis results however, in great loss oit time and involves considerable lworking expenses.
The object ot the present invention is, as already generally stated, to provide means on spraymg apparatus ot the type referred to for emptying the material tank and cleaning the admission member for the material which, without being necessary to stop the working, render it possible to empty instantaneously the tank for the material by means et or without using compressed air and moreover enable a quick and thorough discharging and cleaning. ln consequence ot these improvements any foreign bodies, such as core-nails, hairs ot brushes, pieces ot wood, wood-shavings, stones, pa er-pieces and the like, may bel removed, wit yout stopj ping the working or shuttin olii the compressed air after removal of. a detachable4 cover.. its a result of the improvements forming the subject matter ol this invention the clogged admission member 't'or the material may also be cleaned while the apparatus is in operation.,
rllhe accompanying drawings show', by wa of example, the invention applied to a sanoblast-machine.
lln these drawings:
Figure l is a vertical section on theline llll ot Fig. 2 through a tirst embodiment ot' a sand-blast-machine.
Fig. 9 is a section. on the liner ll-lll ot Fig. l.
Fig. 3 a front view oit the sand-admission-cock.
Fig. l 'is a section on the line llV-ll ot Fig. 3.,
Figs.. 5 and are sections through said cock and parts of the casing occupied by this cock, the cock being shown in these iigures in did'erent positions.
Fig. 7 shows, partly in section, a modication of a detail.
l is a sand tank and 2 a mixing pipe in which compressed.. air admitted in the direction of the arrow shown in Fig. l is mixed with a jet of sand ted vertically trom above. 3 is a pipe through which the resulting mixture of sand and air is conveyed. A vertical pipe 4 branches od trom the mixing pipe 2 at the inlet end and reaches to the upper part of the tank l. The vertical pipe l is to introduce compressed air into the sand tank l in order to maintain constant the flow of sand :trom the said tank. A. valve 5 and hopper 6 are for charging'tlie sand tank l. rl`he admission ot the com- 'l pressed air to the mixing pipe 2 is controlled by means ot a cock 7.
8 is a casing-arranged. below the sand tank l and connected at its upper end in an air-l tight manner to the tank l and at the lower end to the mixing pipe 2. A cock 9 is movably mounted within this casing 8. l0 is a handle tor adjusting the cock 9. Cock 9 is provided with a continuous cross-hole ll terl minating at one end in the passage opening l2. 'll`he cock 9 is also provided with a hollow space i3 communicating at the end lying in Fig'. 2 at the right hand end with the cross-hole ll by means of a bore ld'while at the other end it is open. ln the cylindrical part ot the cock 9 surrounding the hollow space l is provided an yaperture l5, so that the hollow space t3 is also partly ioo open in the circumferential direction of the cock 9. 16 (Fig. 2) denotes a cover arranged near the open end of the hollow Space 13 and detachably secured to the casing 8. rl`he latter is also provided with a passage 17 adapted to establish a communication between the cross-hole 11 and the mixing pipe 2. 18 is a cleaning pipe fixed at one end to the casing 8 and adapted to be shut ofi' by means of a cock 19. 21 is a cock mounted in the outer end of a passage 22 of the mixing pipe 2 and is for controlling the quality of the mixture of air and sand flowing into the pipe 3.
The passageway of the mixing pipe 2 is partly closed by a body 23 which has the form illustrated in Figs.- 1 and 2. This body is fixed in proper position within the pipe by means of a plate 24 which is pressed by an eccentric 25 against said body and an open portion of the pipe. Said eccentric is formed on a lever 26 pivotally mounted on a shaft 27 which is supported parallel to the axis of the pipe in eyes 28 formed on the latter.
The working of the described apparatus is as follows: When cock 9 is moved into the position shown in Figs. 1 and 2 by means of the handle 10, the passages 11, 12 and 17 establish a communication between the sand tank 1 and the mixing pipe rl`he operator may then work with the sand jet. ln the event of an obstruction occurring-and this is nearly always in the narrow passage opening 12 of the Vcock 9-tl1e latter is turned so by means of the handle 10 that the passage opening 12 comes to lie oppositely to that end of the cleaning pipe 18 which lies within the casing 8 (Fig. 5).
rl`he hollow space 13 is then put into communication with the mixing pipe 2 by means of the aperture 15 and the passage 17, while the communication between the mixing pipe 2 and the tank 1 is shut oit. |lhus, compressed air may flow into the hollow space 13 and from the latter through the bore 111 to the passage opening 12. When the cock 19 is opened the opening 12 will be cleared at once, the obstructing matter being forced through the pipe 18 into the atmosphere.
lf, however, the whole contents of the tank 1 are to be emptied, handle 10 is turned in such a 'manner that cock 9 assumes the position illustrated in Fig. 6, so that the aperture 15 establishes a communication between the hollow space 13 and tank 1. rllhe communication between the latter and the mixing pipe 2 is thereby closed and cock 19 is turned od. After the removal of cover 16 the compressed air admitted into the/ tank 1 causes" all the sand to be forced through the aperture 15 and the hollow space 13 and to be blown out into the atmosphere through the opening furnished by the removal of the cover 16.
,ier
The attendance of such a sand-blast-machine is very easy and does not require any skill.
Thus, when for instance a cleaning of the passage opening 12 has to be ettected, all that the attendant has to do is to turn on cock 19 and perform only one further manipulation. ln Fig. 7, 32 denotes a by-pass branching off from the mounted in this pipe 3l. rlhe other end of 'the by-pass communicates with the space of the casing 8 occupied by the cock 9 which is similar to that shown in Figs. 1 6. is a cock in the by-pass 32. rl`hc latter communicates also behind the cocks and 35 with the mixing pipe 2 by means of a pipe 3G. 37 denotes again a cleaning pipe provided with a cock 38.
In the event of an obstruction occurring in the passage opening 12 of the cock 9, the cock 35 is turned on, the cock 33 is turned off and the cocl 9 is turned so, that the openings 11 and 12 establish a communication between the by-pass pipe 32 and the pipe 37, so that upon an opening of the cock 38 comu pressed air flows through the openings 11` 12, and the pipe 37 for the purpose of re-l moving obstructions from the passage opening 12 and force them into the atmosphere. The air passino through the pipe 32 has therebyI the tendency to flow along a straight hne and exerts then a sucking action at the upper end of the pipe 3G, so that, as the cock 35 is turned oft, the escape from the pipe the pipes 36, 2 and 3.
lf the cock 35 is turned oft, compressed a1r passes through the pipe 36 into the right hand end of the by-pass 32. l-lhen the cock 9 1s 1n the position shown in Fig. 7 any el structions in the opening 12 are-'then again instantly removed by the compressed air passing through pipe 3G and the right hand end of the by-pass 32.
