P. H. RIC'HERT DISPENSING APPARATUS Filed Nov. 19, 1938l www re E A. 7 @5m m/ Mm 9 Patented June 6,' 1939 PATENT Lor-FICE z,1s1,o9o DISPENSING APPARATUS o -Paul H. Richert', Fresno, Calif., assigner tov Neil l i A. Maclean, San Francisco. Calif.
Application November' 19, 1938, lSerial No. 241,475 -3 claims. (ci. zal-23) This invention relatesto I an apparatus for facilitatingthe dispensing of a fluid retained in a can. Particularly, the invention relates to provision of an apparatus for dispensing a fluid under pressure from the can. Such a ui'd may be methyl bromide, or other material, having a relatively high vapor pressure at usual atmospheric temperatures, or a fluid having a low vapor pressure at a usual atmospheric temperature but placed under pressure in the can by means of carbon dioxide, ammonia, or other gas or high 4vapor pressure material.
It is in general the object of the present invention to provide a simple but inexpensive dispensing apparatus for a fluid under pressure in a can.
Another object of the present invention is to provide an effective apparatus for facilitating the "dispensing of fluid under pressure from a can.
' In fumigation, for example, methyl bromide -has recently comeinto wide application.' This material has some toxicity to humans and it is l therefore desirable to avoid contact or' breathing of the material as much as possible. Utilizing the apparatus of this invention, one can readily distribute methyl bromide from a can. Thus the apparatus makes possible the release of methyl bromide from a can and discharge through a restricted hole oraperture in the door or wall of a space to be fumigated without the operator having to come into contact with the methyl bromide.
In fire flighting, particularly in the home or :i5 around an automobile, a motor boat, and in other like locations, carbon tetrachloride is widely used. However, if the fire is very hot one cannot get close to it. For most effective operation the carbon tetrachloride should be so placed at the base 4o of the fire that it smothers the flames and cuts off air. The present invention enables the stream of carbon tetrachloride to be directed most effectively.
The invention includes other objects and features of advantage, some of which; together with the foregoing, will appear hereinafter wherein the prsent preferred form of apparatus of this inventionis 1 disclosed.
In the drawing accompanying and forming `a part hereof Figure 1 is a'side elevation of the invention through an apparatus embodying the v present invention.
Figure 2 is the plan view of the apparatus of the present invention, while Figure 3 is an end g5 view showing the apparatus in place on a can.
the fluid under pressure.
It appears ixi the drawing that I A'provide a ik: frame, generally indicated at 6, which is adapted to be attached readily to the can or other receptacle. This frame includes a first strap member 1 having' a hook 8' formed thereon which is en- 5 gaged with rim 9 on the can Il. The first frame member 1 is adjustably attached by screws l2 to a second frame member il so that the length of the can may be readily taken into consideration and so the apparatus is suitable to various height 10 cans.
Mounted on a hinge i6 on member I4 is a can end piercing element. generally indicated at i1. This element includes a conduit I8 for leading off The conduit extends l5 through a suitable support member I9 attached to the hinge i6. In the form of apparatus shown the can piercing element is 'formed as at 2i by sharpening the edge of the conduit. Instead of utilizing the conduit asfa can piercing element, 20 i a suitable cutting element such as a knife or other can piercing device can be employed in con- -junction with the conduit i8. Mounted cooperatively adjacent the conduit and adapted to'be compressed upon positioning 25 of the can piercing element is a gasket 23. 'Ihis gasket engages the end of the can and seals the space about the can piercing element so that fluid 'from the can is forced into the conduit and does not leak out. v
To ensure that the can piercing element is retained at the position in which the gasket 23 is compressed I provide an extension 26 on member is which ext ension has its end formed as a pawl 21, inengagement with a ratchet 28 on a 35 y plate 29, the plate 29 being hingedly mounted as at 3i on member i4. Plate 29 is forced to engage the pawl 21 by a spring 3| positioned on a rod 32. The end of the rod is inserted through and is held by member I4 while the tension of 40 thevspring is suitably adjusted by nuts 33.
In use, the can piercing element and the conduit are normally in that position in whichthey appear in Figure 1. The hook 8 is engaged with can rim, the can piercing element is moved to the 45 left, or counter clockwise, in Figure l whereby the can piercing element is forced through the can at the same time that the gasket 23 is compressed to seal the opening made in the can end. The ratchet and pawl engage and retain the 50 gasket compressed. l
The -can is held in an inverted position during the opening so that liquid covers the opening made in the can and the gas pressure in the can is not immediately released.
can.v The can can then be removed and a new' can inserted. If desired, the conduit I8 can include a suitable valveor other discharge control means. v 1 I claim:
1. A device for dispensing a fluid under pressure in a can having opposite ends comprising a rst means for engaging one can end,*a second means engaging the other can end, including a 15 pawl .and a ratchet retaining said second engaging means in engagement with said other can end, said second engaging means including a can end piercing means and a gasket surrounding said piercing means and forcibly rezo tained against said. can end by engagement of `said pawl and said ratchet.
2. In a device oil the character described. a
with said can upon movement frame adaptedto be positioned on a can, a fluid conduit including a 'cooperating can piercing means mounted for a limited hinged movement on said frame, a gasket cooperatively mounted adjacent said piercing means to seal an opening 5 in said can made by said piercing means and direct iiuid in said can to said conduit, and means for retaining said gasket in sealing engagement of said piercing. means to pierce said can. m 3. Inga device of the character described, a frame adapted to be positioned on a can, a uid conduit including' a cooperating can piercing means mounted for a limited hinged movement on said frame, a gasket cooperatively mounted 15 adjacent said piercing means to seal an opening in said can made by said piercing means and direct iiuid in said can to said conduit, and a paw! and a ratchet for retaining said gasket in sealng engagement with said can upon movement 20 of said'piercing means to pierce said can.
