Patented Nov, 20, 1934 UNITED STATES NOZZLE ATTACHMENT FOR POWDER FILLING MACHINES Charles J. Westin, Philadelphia, Pa., assignor to F. J. Stokes Machine Company, Philadelphia, Pa., a corporation of Pennsylvania Application April 30, 1932, Serial No. 608,432
Claims. (Cl. 226-116) Figure 1 is a vertical cross section through my I device with parts shown in cross section.
Figure 2 is an end view of parts of my device.
Figure 3 is a vertical cross section of a portion of a modified form with parts broken away.
The attachment consists of a nozzle or pipe 1 fastened to a flange 2, which is held to the hopper holding the material by means of holder 15. The nozzle or pipe 1 has'at its lower end the outer peripheral edge beveled off, leaving an unbeveled portion on the bottom of the nozzle, against which unbeveled portion the valve seat can seat firmly over a distance of appreciable width. The beveled portion guards against the clinging of material or dust to the end of the nozzle 1, which material or dust will prevent the proper closing of valve 6, hereinafter referred to. On the lower end of the nozzle is attached a collar 5 which hasprovisions or holes made in it to permit the guide pins 3, which are fastened tovalve 6, to extend up through this collar 50' that the compression springs 4 may be allowed to rest on collar 5 supporting the ,valve by means of the washers and cotter pins at the top of guide pins 3. Valve 6 is held by means of the springs 4 against the bottom edge of the nozzle when no material is being discharged. This valve has a small hole in the center shown at 11 which hole cooperates with the clean-off spud 10 :to prevent packing of some kinds of material beneath the clean-off spud .10 in a ball or pile. This clean-oft spud 10 is an extension of the auger 9 and can be made of any non-circular. form so that when it revolves it throws the material away from under the center of the auger and prevents the material from packing at this point and interfering with the free closing of the valve' 6. The auger is held by a collar 16 to the operating shaft which shaft is driven intermittently by the mechanism of the shaft. -When the auger is put in motion it draws on the supply from the hopper above forcing the 5 material down against the valve 6 which yields to this pressure and allows-the desired quantity of material to be discharged. Spud 10 revolving with the auger prevents material packing between the auger and valve-6 and therefore-allows the, valve to close preventing drip, instantly the auger stops.
This method of controlling the flow is very simple but has been found in actual practice to be surprisingly accurate in regulating the amount of powder discharged by the machine.
When machines are operated at a high rate-of speed, material is fed so rapidly that dust or float is created by the air rushing from the container. To prevent this escape of dust suction hood 13 is provided, having an air exhaust connection 19, which can be attached to any suitable exhaust system and the dust collected. To make this v more effective a felt pad '7 may be fastened to the bottom of the suction hood 13 as shown. Exhausting the air in this manner not only removes the objectionable dust but aids in evacuating the can, thus increasing the speed at which a container may be filled. The opening between the felt ring '7 and the outer wall on suction ring 13 may be, and sometimes is, closed by the size of the container to be filled. The suction is then connected to the inside of the container bein filled by means of perforations 44 formed on an angle from the vacuum chamber above the felt ring 7 in a direction toward the center or outer '85 rim 8.
Where containers have very small openings a funnel 14 is provided which permits the use of a larger diameter of auger relative to the opening of the container. This accelerates the speed at l0, which such small mouth containers can be filled and adds greatly to the capacity of the machine. Funnel 14 has a flange 17 on it which carries a pad 18 for making a tight seal between the funnel and the container to be filled.
I do not intend to be limited in the practice of my invention save as the scope of the prior art and of the attached claims may require.
