APPARATUS FOR SPRAYING EOLTEN SUBSTANCES.
Application filed August 19, 1927, Serial No. 214,032, and in the Netherlands September 3, 1926.
type comprising a container fitted with a nozzle through which the molten substance is ejected by air or gas under pressure, the object of the invention being to provide 1mproved means for applying the compressed air or gas to the interior of the container.
According to the present invention a container is provided with a cover having a passage with ports at its inner and outer surfaces and a hollow lever or clip having inlet and outlet openings is arranged to exert pressure on the cover with the lever outlet registering with the outer port of the cover passage. A supply of compressed air or gas is connected to the inlet opening of the hollow lever which thus is used both to conduct the compressed air or gas to the container and to close its cover.
Preferably the hollow lever bears against an adjustable stop on a projection of the container at one side of the cover and is connected to the container-by a resilient ornonresilient link at the other side of the cover. If desired the lever may serve as a handle for the container and its accessories. The cover may be fitted with two projecting lugs between which the hollow lever may be retained by a pin engaging holes in the lugs.
The inner port of the coverpassage may be protected by a plate or shield from spat-' tering material melted inside the container.
The accompanying drawing is a sectional elevation of apparatus for spraying molten substances according to the present invention, the container 1 being'heated for melting its contents or for keeping them in -a molten condition by a suitable burner (not shown on the drawing) attached to a projection or the like 2. The molten contents of the container 1 are ejected through its front part which is also exposed to the flame of the burner, and this part is of such shape (as illustrated) that the heat of the flame is utilized as much as possible. The flame from the burner is guided along the wall of the container 1 in a passage or flue formed by a protective deflector shield 3 which also serves as a clamping piece for a nozzle 4 face around one end of that bore fitting a corresponding faced edge around an opening in the container 1. of the bore'the nozzle 4 is provided with a reduced portion and a tubular ring 5 fits around this reduced portion and the main body of the nozzlet. This tubular ring 5 supplies the compressed air or gas for spraying the material leaving the mouth of the nozzle 1. For this purpose perforations 6 of suitable size and shape to produce the required jets of air or gas are provided in the tubular ring, and open near the mouth of the nozzle 4. The tubularjet ring 5 is connected with. and may form part of, a tube 7 for the supply of the compressed air or gas.
The protective deflector shield 3 is provided with an opening to surround the perforations of the jet ring 5 and the shield acts as a clamping piece being provided with screwed rods 8 disposed between lugs 9 at each side of the container l. Nuts 10 and washers 11 are fitted tothe screwed rods 8 and by screwing up these nuts 10 the protective shield 3 is drawn against the tubular jet ring 5 and the latter against the nozzle 4 which is finally pressed against the container 1 so that in this manner all the parts mentioned are clamped together, and the nozzle and jet ring may be readily removed and replaced, the nozzle forming a distance piece determining the width of the flue around the container provided by the shield -3.
The bore of the nozzle 4 is formed with a conical portion facing inside the container 1 to form the seat for an adjusting needle valve 12 which is disposed across the container and passes through. a stuffing box 13 fitted to the wall of the container opposite to the nozzle 4. Means for adjusting the valve 12 are provided outside the container At the other end 1 for which purpose the needle may be 4. Preferably, however, the needle 12 is adjusted by a simple axial movement.
For ejecting the contents of the container through the nozzle 4: compressed air or gas container 1 through a hollow lever which is also used to close the cover of the container, in the following manner.
The container 1 is provided with a filling cover 16 which is closed by means of pressure exerted by a hollow lever 17. One end of this lever may be forked at a solid part' and engages a nut 18 which is screwed to a projection 19 of the container 1. The lever 17 extends across the cover 16 and on the other side thereof is connected in any suitable manner to the container 1, preferably by means of a spring 20 or other form of link extending from the neck of the stutiing box 13. The lever 17 is formed with an enlargement 21 through which an out-let from the hollow interior of the lever is provided and the cover 16 is formed with a passage 22 having ports at its inner and outer surfaces, the parts being so disposed that the outlet of the lever 17 in the enlargement 21 registers with the outer port of the passage 22 so that the interior of the lever is connected with the interior of the container. The lever is also fitted with an inlet opening at 24 to which the branch pipe leading from the supply pipe 7 at 15 is connected. In this manner compressed air or gas is conducted from the supply pipe 7 through the branch pipe, hollow lever 17, and the passage 22 of the cover 16 to the container 1. The branch pipe may be provided with a regulatmg valve and in the drawing a further valve 25 in the main supply pipe is also shown.
The outlet port of the passage 22 through the cover 16 is preferably situated between two projecting lugs 26 of the cover 16, the
lever 17 being situated between the lugs 26. These lugs may be perforated above the lever as shown so that the latter may be retained by a pin engaging the holes.
A handle 28 may be provided on the lever 17 for holding the apparatus. I
The inner port of the cover passage 22 is preferably protected from being obstructed by spattering material melted inside the container by a plate or shield 27 fitted to the cover.
What I claim is 1. In apparatus for spraying molten substances, the combination of a container, a'-
cover therefor having a passage with ports at its inner and outer surfaces, a hollow lever having inlet and outlet openings, means for enabling the lever to exert pressure on the cover with the lever outlet registering with the outer port of the cover passage and means for connecting a supply of compressed air or gas to the inlet opening of the hollow lever, substantially as specified.
2.
