page_text: I, DAVID SIME CARGILL, of 191 West George Street, Glasgow in the County of the
City of Glasgow, East India Merchant (a communication from abroad by The Burmah
Oil Coy. Ltd., Rangoon, Lower Burinah,) do hereby declare the nature of this
invention to be as follows:-
This invention relates to apparatus for filling oil tins automatically from the main or
storage tank.
In carrying out my invention I employ a set of two circular or other shaped oil
cans or tanks mounted upon a suitable frame, each can being provided at the top
with an inlet cock or valve leading from the main oil supply pipe and at the bottom
with a discharge cock or valve for emptying the contents into the commercial tins or
drums.
The inlet and outlet valves of each can or tank are operated by means of two short
levers connected to a main or doubled armed lever by means of slots and pins, the
main lever being mounted so as to slide in guides upon the main frame; the
arrangement being such that when the main lever is forced forward it opens
the discharge and closes the inlet of the one tank and closes the discharge and opens
the inlet of the other tank thus filling the cans alternately. If desired I may employ
two, three or more sets of tanks.
I also employ means for automatically feeding the commercial tins or drums below
the discharge or outlet of the oil tanks, consisting of an endless band for each tin
having small or other shaped rails or guides so that the tins are always in the
correct position below the discharge.
At each side of the main frame and at a suitable distance from the tanks is mounted
a shaft upon which the endless bands work by means of chain and sprocket wheel,
secured at each side of the band, the driving wheels of the one band being keyed
to one of the shafts while the wheels at the other end run loosely upon the second
shaft.
The second band is mounted reversely to the first in that the driving wheels are
keyed to the second shaft and the wheels at the other end run loosely upon the first
shaft.
Both shafts are operated by a hand lever having a double acting pawl engaging
with (in the case of the first shaft) a ratchet secured to a large sprocket wheel
connected to a smaller sprocket wheel, keyed on the shaft, by a chain; and in the
case of the second shaft a ratchet secured to a spur wheel engaging with a smaller
spur keyed on the shaft; the action being that when the lever is operated in the
rigl.t hand direction the pawl will engage with the ratchet upon the sprocket gear
and move the band containing the full can forward thus enabling a second can to be
placed in position.
When the turning the lever in the left hand direction the pawl engages with the
ratchet upon the spur gearing and moves the other can forward in a similar manner
to the first; the arrangement being that they are both fed forward alternately.

page_text: Or I may mount the lever so that it can be operate l in the reverse directions to
the foregoing.

Apparatus for Filling Oil Tins.
I, DAVID SIME CARGILL, of 191 West George Street, Glasgow, in the County of the
City of Glasgow, East India Merchant (a communication from abroad by The Burmah
Oil Coy. Ltd., Rangoon, Lower Burinah,) do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention relates to apparatus for filling oil tins automatically from the main
or storage tank.
DESCRIPTION OF DRAWINGS.
Figure 1 is an elevation partly in section
Figure 2 a plan.
Figure 3 a cross section
Figure 4 an end view of my apparatus and
Figs. 5 and 6 detail views.
Referring to the said drawings I employ a set of two circular or other shaped oil
cans or tanks A A', mounted upon a frame B each can being provided at the top
with an inlet cock or valve C, C', respectively leading from the main oil supply pipe D,
said pipe being provided with a regulating cock or valve and index plate d, and at
the bottom with a discharge cock or valve e c¹ for emptying the contents into the
commercial tins or drums E E'.
The inlet and outlet valves of each can or tank A, A', are operated by means of
two short levers F connected to a main or doubled armed lever G by means of slots f
engaging with pins' secured to the main lever. The main lever is mounted so as to
slide in guides b upon the frame B, the top guides being provided with wheels or
pulleys for facilitating the working of the lever. The arrangement is such that
when the lever is forced forward, it opens the discharge and closes the inlet of the
tank A, and closes the discharge and opens the inlet of the tank A', the reverse
happening when the lever is pulled outwards, thus filling the cans E, E¹,
alternately.
To enable the attendant to know exactly when to operate the lever and discharge
the contents I may if desired (as shewn in Figures 5 and 6) employ an electric alarum
bell so arranged that it rings whenever the tanks are full.
For this purpose I provide one of the sets of tanks with a bar A² adjustably
mounted on brackets A secured to the sides of the tanks; the said bar A' carrying
guides A within which the spindles of two floats A work, one float being mounted
in each of the tanks.
The said har has also mounted upon it two non-conducting blocks having
contacts A secured thereto to which the wires of an ordinary electric bell battery are
secured by binding screws.
The arrangement of the floats is such that as soon as the tanks are full a contact
terminal A secured to the upper end of the spindle of the float is caused to complete
the circuit between the contact A and thus ring the bell.

page_text: A cover A is also provided for protecting the various parts.
If de-ired I may employ two, three or more sets of tanks.
I also employ means for automatically feeding the tins or drums E, E¹ alternately
below the discharge or outlet cocks c, c¹ of the oil tanks A, A' consisting of endless
bands H, H one for each tin, composed of small or other shaped rails or guides h
the ends of the rails resting upon guides h¹ secured to the main frame, so that the
tins are always in the correct position below the discharge.
At each side of the main frame B and at a suitable distance from the tanks are
mounted shafts J, J' upon which the endless bands H, H' work by means of chain
and sprocket wheels j, j', the driving wheels j of the band H being keyed to the
shaft J while the wheels run loosely upon the shaft J¹.
The band His mounted reversely to the first in that the driving wheels ; are
keyed to the shaft J and the wheels run loosely upon the shaft J. The loose
wheels are retained in position on the shafts by collars j.
Both shafts are operated by a hand lever K having at its lower end a double
acting pawlk which in order to operate the shafts J engages with a ratchet k¹
secured to a sprocket wheel L, said wheel being connected to a smaller sprocket
wheel L', keyed upon the shaft J' by a chain l.
The shaft J is operated by the pawl k engaging with a ratchet k² secured to a
spur wheel M engaging with a smaller spur M¹, keyed upon the shaft. The hand
lever K sprocket wheel L and spur wheel M are mounted upon a shaft N secured
to the side of the frame B.
As shown in the drawings, when the lever K is operated in the right hand
direction the pawl k will engage with the ratchet upon the sprocket gear and
operate the shaft J containing the driving wheels of the band H' thus moving
the tin E, which is now full, forward and placing another tin below the
discharge.
The lever G is then forced forward and opens the discharge to the tin E so
that when filled the lever K is operated in the left hand direction, the pawl k
engaging with the ratchet k upon the spur gear and operating the shaft J which
has the driving wheels of the band H keyed thereon, thus moving the tin E forward
and placing another in position, the arrangement being that both tins are fed
forward alternately.
Or I may mount the lever K and gear, that it can be operated in the opposite
directions to the foregoing.
The bottom of the main frame B is formed as a tank so as to retain any oil that
may be spilled or leak from the tanks above.
It is to be understood however that I do not limit myself to the precise details
above described as any mere mechanical equivalents of the same may be employed
without departing from the scope of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The apparatus for filling oil tins from the main or storage tank, as described
and shown.
2. In apparatus for filling oil tins from the main or storage tank, the arrange-
ment of the inlet and outlet cocks C, C, c, c' of the tanks A, A', with their levers
or arms F, and the lever G working in guides b upon the frame B, for
operating the arms, or the mechanical equivalent of the same, as described and
shewn.
3. In apparatus for filling oil tins from the main or storage tank, the endless
bands H, H composed of 1 or other shaped rails or guides for the purpose of
feeding the tins correctly below the discharge of the tanks A, A', the ends of the
rails resting upon guides h' and operated by sprocket wheels i, j, or the mechanical
equivalent of the same, as described and shewn.
4. In apparatus for filling oil tins from the main or storage tank, the means for

page_text: operating the bands H, H', so that they are moved forward alternately, consisting of
the hand lever K having a double acting pawl k which engages with a ratchet
upon the chain and sprocket gearing for actuating the band H and with a ratchet
upon the spur gearing for actuating the band H, or the mechanical equivalent of
the same, as described and shewn.
