Wilfred H. Shields WW EM United States Patent MEASURING DISPENSER FOR EXPLOSIVE INGREDIENTS Wilfred R. Shields, Pittsburg, Kans, assignor of forty per cent to Adolphus Clark, Prcher, Okla.
Application May 18, 1954, Serial No. 430,554
6 Claims. (Cl. 222-148) This invention relates to a measuring dispenser and I particularly to a dispensing device to load highly sensitive powder in the suitable receptacles.
In the operation of charging highly explosive mixtures such as priming mixtures in the suitable containers such as the priming caps for cartridges, a great many blows or explosions result because of the striking of a spark from a portion of the machine, or because of the accumulation of the powder in some portion thereof and a consequent application of pressure thereto to cause a breaking of the grains.
The present invention relates to a charging device utilizing soft or non-spark producing metal such as copper or aluminum and having side portions constructed of such material as conducting rubber so that there will be no electrical sparks or sparks struck from it any hard metal and in order to prevent accumulation of portions of the explosive, suction devices are provided for drawing the loose portions of explosive mixture from the top of the dispensing slide so that there can be no accumulation thereof.
It is accordingly an object of my invention to provide an improved explosive dispenser.
It is a further object of the invention to provide an explosive dispenser having its parts constructed of nonspark producing and high heat conducting material.
' It is a further object of'the invention to provide a measuring dispenser having means for cleaning the residue material therefrom.
Other objects and many of the attendant advantages of the present invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
Figure 1 is a perspective view of the measuring dispenser according to the invention;
Figure 2 is a cross section through the device taken substantially on the plane indicated by the section line 2-2 of Figure 1;
Figure 3 is a cross section across the device taken substantially on the plane indicated by the section line 3-3 of Figure 1;
Figure 4 is a longitudinal sectional elevation taken substantially on the plane indicated by the section line 4-4 of Figure 1; and
Figure 5 is a view similar to Figure 4, .but showing the measuring slide moved to discharge position.
In a measuring dispenser according to the invention, a base plate is constructed of copper, aluminum, or other suitable soft non-sparking material having a high thermal conductivity. A discharge aperture 12 is provided in the base plate 10 and a suitable guide track 14 is provided adjacent one end of the base plate 10.
A guide frame consists of parallel side guide members 16 and 18 and an end guide member 20. Amp plate 22 is mounted in the space between the guide rails 16 and 18 by means of suitable transverse mounting straps 24 and 26, the plate 22 being connected to the cross mounting straps 24 by means of a setscrew 28 and to the cross ice strap 26 by means of a setscrew 30. The ends of the straps 24 and 26 are mounted on the base plate 10 by means of the screws 32 and 34 applied through the strap 24 and screws 36 and 38 applied through the strap 26 and extending into suitable threaded apertures in the base plate 10 and having springs 40 thereon for lifting the straps 24 and 26 away from the base plate 10.
The side guide bar 16 is secured to the plate 10 by means of a cap screw 42, guide bar 18 is secured to the base 10 by means of the cap screw 44. Likewise the end bar 20 is secured to the base 10 by means of a cap screw 46. Y
A dispensing slide 50 is mounted in the space between the guide bars 16 and 18 and fills the space between the base 10 and the top plate 22 with the plate being relatively snug therein so that there is little if any place for explosive grains to be caught on top of the slide. The slide 50 is constructed of suitably electrically conducting rubber so that there will be no sparks between the rubber and the metal adjacent thereto. The slide is provided with a measuring aperture 52 and it will be apparent that the thickness of the slide 50 may be changed to provide different capacities for the measuring aperture 52.
An upper mounting block 54 constructed of suitable material such as rubber is mounted on the plate 22 and a hopper 56 will be received in a suitable aperture 58 of the mounting block 54. The top 22 being provided with a feeding aperture 60 thus communicates with the output bore 62 of the hopper 56, the mounting block 54 being secured to the top plate 22 by means of cap screws 64 and 66.
A driving pitman 70 is mounted in the guide channel 14 of the base plate 10 and is retained therein by means of cross straps 72 and 74 mounted on the extending ends of the guide bars 16 and 18, the retaining bar 72 being secured to the guide bar 16 by the cap screw 76 and to the guide bar 18 by the cap screw 78. Likewise, the strap 74 is secured to the side rail 16 by means of a cap screw 80 and to the side rail 18 by the cap screw 82. The driving bar 70 is connected to the measuring slide 50 by means of a pair of cap screws 84 and 86. Preferably the end of the bar 70 is bifurcated as at 88 to receive the slide member 50 with the screws 84 and 86 extending substantially through the slide bar 70.
An anchoring pin 90 is placed in the guide bar 74 and a similar pin 92 is mounted in the push bar 70 and a spring 94 is mounted between the pins 90 and 92 thus urging the bar 70 to withdraw the slide 50 until the apertures 52 and 60 are in alignment so that the device will normally stand in charging position. In order to move the slide 50 into discharging position so that the aperture 52 will be in register with the discharge aperture 12, a cam device 98 mounted on a drive shaft 100 and driven by a suitable device (not shown) is engaged by means of a cam follower roller 102 mounted in a bifurcated bracket 104 having a threaded stem 106 in threaded engagement with an aperture 108 of the push rod 70 and a lock nut 110 is provided on the shank 106 so that the follower 102 may be adjusted at will with respect to the push bar 70 and locked therein by means of the nut 110.
In order to prevent the accumulation of explosive grains on the surface of the slide 50, the top plate 22 is provided with transverse recesses and 122 which extend transversely of the plate 22 and are arranged substantially just outside the limit of movement of the aperture 52 so that any material which is received on the top of the slide 50 will come in communication with the recesses 120 and 122 and suitable connections such as the conduits 124 and 126 are provided in communication with the recesses 120 and 122, respectively, with the conduits being connected to any suitable suction pump I (not: shown): so that the suctionwill create a flow of air through the recesses 120ml 122 and carry away any: i I
' grains of the explosive mixture which .might be 'en- 't'ra'pe'd on'the top of the'slide 50. I I I Y 1 Preferably similar recesses i136 and 132 will be pro- 'vided in'thc bottom plate 10'and will also communicate: with; the conduits 124i and 126 so that there will be no I danger of accumulated grains bielow'the'slid'e' 50; i I
' i in the operation of the device according to theinven a m, the i slide .50 will be selected I which provides the exact charge desired land the plate 22 adjusted to snag engagement therewith, and a small quantity of thee: plosive mixture Will be placed in the hopper 56 and'the cam 98 will 'be' rotated to cause successive feeding of, l charges through the discharge aperture 12' where it will i be received. by anysuitable mechanism (not shown); I I
- For the purpose of exemplificatijon a particular em- I I l bo'di'mfent of theiinvention ha's'be'en shown and described according to the best present understanding thereof. However, it will be apparent to i those skilled in the art that, various changes and modifications in theconst'ruction i i {and arrangements of the 1 parts thereof may be readily vresorted to without departing from the true spirit and i I scope of the invention. I I I i I What is claimed as new is as follows! ing with the opposite faces of said slide throughout the width of the slide, and means opcratively connected with said passages for removing powder accumulations from said slide during reciprocation thereof.
