H. H. SMITH. DISPENSING APPARATUS. APPLICAHON FILED SEPT.4.191B.

0F HULKOL, fir-HAI, CHOSEN, KOREA..
:DISPENSING APPARATUS.
Application led September 4,
To all 'whom t may concern.'
Be it known that I, HAROLD HARDY SMITH, a subject of the King of Great Britain and Ireland, and now residingat Holkol, Whang-Hai Province, Chosen, Korea, have invented certain new and useful Improvements in Dispensing Apparatus, of which the following is a full, clear, and exact description.
This invention relates more particularly to an apparatus for feeding oils or other :re-agents to iiotation plants. 1
One of the objects of the invention is to so construct a device feed evenly and continuously and in any quantity anything of this nature from the thinnest oils to the thickest tars. .x i
Anotherobject is to so construct the outlet so as to permit any foreign" matterin the oil or re-agent to escape from the tank without choking the outlet and interfering with the normal flow, which object is of great importance in feeding cheap, heavy re-agents such as coal-tar, crude loils, aeidsludge, etc.
Other objects will appear from the following description and claims. ,f
Referring to the drawings in which like reference characters indicate lileparts; A
Figure 1 is a vertical section throughthe apparatus showing the `outlet pipe partly broken away, and the valves in elevation, the outlet valve being seated.
Fig. 2 is a section through the air valve.
Fig. 3 is a detail in section of the outlet, the valve being raised from its seat.
Referring tto the drawings:
A is a suitable containing vessel for the oil or re-agent, which is made of such material that its sides, bottom and top are unyielding and preferably of such dimensions that its height is less than its width. This containing vessel is preferably, mounted upon blocks or legs 10, which latter rest upon a suitable base B. At any suitable point in the top or roof 11, I providean opening or hole 12 which is stopped by a screw plug 13, so iitting that when closed it is rendered air-tight. At the bottom of the containing vessel, preferably at one edge is an outlet pipe 14 fitted to coincide with, an outlet 15. 16 is a cup or basin tted to -the bottom of the container and of such dimensions that its sides 17 extend above. and around the nozzle or outlet 18 of the pipe 14:. It is therefore seen that when this.
Specification of Letters Patent.
of this kind that it will `Patented Sept. 2, 1919. 191s`.` serialno; 252,616.
@up er basin 161s sued with than, an air Seal is formed for the outlet. 20 is the overflow lip of the cup 16, and 2l is a hood or cover secured to the side of the contalher so as tocompletely cover the cup, and over-flow lip. i
`Mownted on the hood is a valve 25 constructed and arranged to be seated upon the outletof the pipe 14 to completely close the same and `to be raised therefrom to open thee` outlet. l This valve is' conventionally shown in Figs. l and 3`and is provided with a head 26 at one end and a screw-threaded stem 27 and an operating handle 28 at the other," `end thereof. The screw-threaded stem` 27 passes through an opening fitted with screw-threads 2 in the top of the hood 2`5and` soI engages the `screw-threads that upon turning the` handle 28, the valve is either lifted from or lowered to its seat at the outlet ofthe pipelll,
The screw-threaded shank engaging with suitable screwfthreads in a block 29 secured to the cup of the hood isclearly shown.
y 30 is an airvalve of special construction `mounted on the top or roof of the container for controlling the air-leak into the top of the container A. 3l is an air-lter provided witha suitablescreen shown at 32 for preventing dust from entering through the air valve` 30, the filter being connected by a pipe 734 to the valve `chamber 35. `Within the valvel chamber 35 is a rotatable plug valve mounted `on the journals37 and `37 to one ofwhich journals is secured a pointer 38 which indicates the position of the valve on the indicator scale 39. In the surface of the` valve I provide a tapering groove 40 cut about three-iquarters around the periphery of the valve plug, so as to pass centrally of the inlet and outlet ports which are situated at a suitable angle from oneanother as shown'.` It is obvious that the angle between the inlet and outlet ports is dependent upon the length ofthe tapering groove `4l0,and therefore the exact construction as shown in Fig. 2 is merely illustrative. As thevalve plug is rotated the passage leading from the inlet to the outlet gradually increases in size. By taperlng the groove out to a hairs thickness, a very small aperture can be obtained, and this aperture may be enlarged` as desired. By moving the groove entirely past the inlet, the valve 1s completely closed.
41 have found that ,in changeable weather the oil feeder should be 'protected against thevvorifice of theoutlet pipe 14 andthe stopi agile.'
per 1S ,is removed from Ythe top of the tank. The tank 'is then iilled'with the material to be dispensed and the stopper plug 13 is replaced and screwed down into lits seatV air- The lair valve 30 is then shut and the outlet valve is opened which will then cause a heavy How of the -material to take place Iover the l-ip`20avhich is caught in a .suitable ,vessel and reserved for `future use. The .flow of material will then fall off and finally cease because of the fact that no air is entering into the top off the tank 'as an effectual-air `seal is provided at the -bottom of thel tank by means of the liquid filling the cup or basin r16, The 'air valve 30fis then adjusted Lto admit the requisite amount of airuntil the required flow is` obtained over the lip 20. Theapparatus will then feed evenly and continuously and vin any quantity so that the liquid contained therein will loe evenly and continuously dispensed.
Ilt ist@ be understood that I ,do not limit myself to the particular shape yor form of any part herein. shown, neither do Illimit l myself to the precise `arrangementofthe parts .with 4respect toy each other. v
vIt Vis furthermore to be understood `that the `above description and drawings are merely illustrative and that the invention is not to be limited in any respect except as defined inthe sub-joined claims.
Having now described vmy invention, what I claim as new and desire to secureby Letters Pat ent,'is:
v1.,A dispensing apparatus comprising a container for the material tobe dispensed, provided at the bottom thereof with. an air vsealed outlet, and atthe top with an air inlet,v a valve for the said outlet and a valve ,l forsaid jinlet, the latter valve being constructed to control by uniform gradations the {iow of air therethrough.
A dispensing apparatus comprising a container for the material to be dispensed, -provided atvthe bottom thereof with an air sealed outlet, and at the top with an air inlet, a valve for the said outlet and a valve for said inlet, the latter valve being constructed to `control by uniform gradations the flow of air by increments therethrough.
3. A dispensing apparatus lcomprising a container for the material to be dispensed, provided at the bottom thereof with an air sealed outlet, and at the top with an air inlet, a valve for the said outlet and a valve for said inlet, the latter valve being constructed to control by uniform gradations the How of air by decrements therethrough.
4L. A dispensing apparatus comprising an airftight container Afor the material to be dispensed, said container being provided at the bottom with an outlet, a liquid seal and a permanent valve for said outlet, an air valve for admitting air to the top of the con tainer, means for regulating the {ioW of air lby uniform gradations past said valve and an indicating device therefor.
:5. A dispensing apparatus comprising an air-tight container for the material to be dispensed, said container being provided at the bottom with an outlet, a liquid seal and a permanent valve for saidoutlet, an air valve for admitting air "by uniform gradations to the top of the container, and means for regulating the How of air past said valve.
' 6. A dispensing apparatus provided at its bottom with an outlet, a liquid seal and a permanent valve controlling said outlet, means at the top of the container for supplying the material to be dispensed thereto, means for closing the same air-tight, an air valve also at the top of the container constructed to control the fiow of air by increments pastfsaid valve and means for indieating the positions of said valve.
In witness whereof I have hereunto set my hand at Seoul, Chosen, in the Empire of Japan, thisBrd day of August, 1918.
