PROVISIONAL SPECIFICATION.
Improvements in Oil Vessels for Oiling Machinery and other
like purposes.
I, GEORGE HARRY WILLIAM DAVIS, trading as G. H. W. Davis & Co.
of Edgbaston Works, Gough Road, Birmingham in the County of Warwick
Lamp Manufacturers, do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object improvements in oil vessels for oiling machinery
and other like purposes which is applicable for such like purposes as the oiling of
cycles engines, shafting and machinery generally besides being exceptionally
applicable to overhead work where there is no room to invert an oiler.
In the case of a simple oil vessel for the bench and general use including cycles
1 take a cylinder or tube of convenient length and cover the back end with a
removable cap for the purpose of filling the oiler. Then a little distance from the
point or delivery end I fit in a division having a central hole through which the
oil is delivered. The point or spout is provided with a collar underneath which
the tube is parallel and having a piston formed by a leather or other packing
which works in the cylinder a projecting neck passing through the hole in the
division into the oil vessel and finishing with a washer bearing against the division
when in its normal position in winch position it is maintained by an internal spring.
To inject the oil the hand is pressed upon the upper collar or projection which
overcomes the spring and forces the piston downwards which carries the washer or
valve from the back of the division and forces the oil through the delivery point.
The point may of course be fitted with a screw or other cap as an extra safeguard
against the leakage of the oil. The piston opening is fitted with a suitable gland
cap which may be either screwed on to the vessel or fit by friction or other
means.
Another form is to fit a spout or delivery pipe in a supplimental tube by the
side of the main vessel the base of the spout having a hole corresponding with the
inlet hole in the main vessel but when turned round shuts the opening. In this
case the piston is simply worked above the hole into the vessel and is kept in its
upper or normal position by a spring externally placed on the piston rod which
finishes with a disc for the point of the finger. When the spout is turned to the
open and the piston pushed down the oil is delivered. An alternative plan to this
is to fix the spout to a branch piece from the main vessel finishing with a hollow
cock or a screw or stop valve to shut off the inlet, the piston being operated as
above described. But by fixing the spout at the lower position of the vessel near
the filling cap the oiler will inject the oil upwards through a curved point piece
until the vessel is nearly empty, which is a great convenience in oiling shafting
and other parts of machinery near a roof or ceiling.

Improvements in Oil Vessels for Oiling Machinery and other
like purposes.
I, GEORGE HARRY WILLIAM DAVIS trading as G. H. W. Davis & Co.
of Edgbaston Works Gough Road Birmingham in the County of Warwick, Lamp
Manufacturer do hereby declare the nature of my said 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 has for its object improvements is oil vessels for oiling machinery
and other like purposes which is applicable for such like purposes as the oiling of
engines, shafting, and machinery generally besides being exceptionally applicable
to overhead work where there is no room to invert an oiler.
'
In the case of a simple oil vessel for the bench and general use including cycles
I take a cylinder or tube of convenient length and cover the back end with a
removable cap for the purpose of filling the oiler. Then a little distance from the
point or delivery end 1 fit in a division having a central hole through which the
oil is delivered. The point or spout is provided with a collar underneath which
the tube is parallel and having a piston formed by a leather or other packing
which works in the cylinder, a projecting neck passing through the hole in the
division into the oil vessel and finishing with a wusher bearing against the division
when in its normal position in which position it is maintained by an internal spring.
To inject the uit the hand is pressed upon the upper collar or projection which
overcomes the spring and forces the piston downwards which carries the washer or
valve from the back of the division and forces the oil through the delivery point.
The point may of course be fitted with a screw or other cap as an extra safeguard
against the leakage of the oil. The piston opening is fitted with a suitable gland
cap which may be either screwed on to the vessel or fit by friction or other
means.
Another form is to fit a spout or delivery pipe in a supplemental tube by the
side of the main vessel the base of the spout having a hole corresponding with the
inlet hole in the main vessel but when turned round shuts the opening. In this
case the position is simply worked above the hole into the vessel and is kept in its
upper or normal position by a spring externally placed on the piston rod which
finishes with a disc for the point of the finger. When the spout is turned to the
open and the piston pushed down the oil is delivered. An alternative plan to this
is to fix the spout to a branch piece from the main vessel finishing with a hollow
cock or a screw or stop valve to shut of the inlet, the piston being operated as
before described. But by fixing the spout at the lower position of the vessel near
the filling cap the oiler will inject the eil upwards through a curved point piece unti!
the vessel is nearly empty which is a great convenience in oiling shafting and other
parts of machinery near a roof or ceiling.
In order that my invention may be clearly understood and more easily carried
into practical effect. I have appended hereunto two double sized sheets of drawings
showing in the same as to several modifications which will enable others to apply
the principle to oil cans of various shapes and for various purposes.
Figure 1 shows one of my oil vessels for oiling machinery either overhead or in
other positions difficult to reach by means of the long spout. B which extends to
the point which may be of any desired shape and it extends internally to b'.
The spout B is connected to the front cover at the fast neck c¹ by the rod or
wire E; ate to the spout B; and ate to the projection e' on the cover C. S is
a tubular sleeve with its glands working easily upon the root of the spout 13 and
it is maintained in its outward position by an external spring (not shown) but fixed
ats or it may be a tension spring inside the case or cylinder A which forms the

page_text: oil containing vessel. To the internal. portion of the sleeve S is fixed a piston P
with its leather or other packing L. The bottom end of the vessel A is sealed
with a cap K made tight by a washer. The action is very simple:-One hand
holds the horns or projections H while the vessel A is pushed towards H when
the oil or other contents of the vessel A is ejected at the point 6 of the spout B
through the internal holes under the piston P the lower end of the sleeve S being
sealed.
Figure 2 is a small oiler for sewing machine or cycle use having a bridge k
with a rod R and spring T for operating against the piston P which is fast to the
spout B. The oiler is shown upon the drawings in its compact form for carrying
in a bag which is done by pressing the cap N on the end of the spout B forcing it
inwards against the spring T until the flanges n' of the cap N can be turned under
the hook pieces ³. When in use the cap N is removed when the spout B projects
out of the casing A and when the point of the spout is put against anything to be
oiled it is only necessary to push the casing when the oil is ejected to the required
position.
Figure 3 is a similar oiler to Figure 7 but the spout B extends downwards by
the side of the vessel A with two branch outlets and 6. The upper outlet b³ is
fixed at the side of the spout B and bis on the centre of B. Each of these
branches have an internal cap with a hole in the neck as seen in section at
the lower brauch so that by turning the caps their hole 6 may be turned to
communicate with the spout or to shut the passage and both may be open at once
or only one. In this modification the tube S is only a piston rod fixed to the
piston and working loosely with a good fit in the upper portion being held
outward by the spring T which is attached to the sliding piece M. The hinged
spring cap d is pivoted at d' with the heel spring d³ always tending to keep it
tight, but the cap may be lifted to allow air to enter through S, which in this case
is open at its lower end. The action is similar to the oiler Figure 1 as it is only
necessary to press d downwards, when one or both the openings 6 being open the
oil will be ejected when desired. When this oiler is used for overhead work and
the supply inside A is low it is necessary to open the bottom outlet 6. The bottom
cap K in this case screws against a washer k which is held by a collar & having
an opening for charging. Another charging arrangement is shown by Figure 4
where the thumb screw is tapped into the bridge 4, this bridge leaving spaces
on each side for charging the oil. The collar is fast to the washer so that
when the screw is turned to carry the collar and washer inwards the vessel A
is open to receive a supply of oil. Figure 5 is a plan of the lower end of Figure 4
showing the nut and its parts.
Figure 6 shows one of my oilers somewhat different in its smaller details. The
bottom stopper K is used and the bridge or cross bar leaves space at each side
to fill the cylinder or casing A while 4 is a socket to receive the base of the spout B
with a hole through which the oil passes to the spout B when the hole is in
position to receive it, but as shown upon the drawing the spout is turned round and
the supply is cut off. At the top end the cover or cap C has the neck c' with the
slot cut out in which the key or projection or guide piece s works to prevent
the sleeve S turning round and the spring T keeps the hands H outwards. The
key or rib s continues down to the piston P the piston being made tight by the
ring of leather or other packing L. The sleeve S has the slot at its lower end
and the spout B has a hole 7 which may be open as shown when the oiler is ready
for work or by turning round the spout B the hole is closed behind S and the
bottom hole is open so that the vessel A may be quite emptied even while the
oiler is worked in a vertical position for overhead oiling.
The broken off oiler shown by Figure 7 is simply the lower or back end of
the casing A to illustrate one mode of ejecting the oil by means of the plunger V
which has an enlargement or Hange at the other end under which the washer or
packing of leather or other soft material L is situated. There is also a bridge
piece which leaves an opening for oil on each side in which B slides. It will be

page_text: observed that the opening af is open to the oil in the position in which it is shown
in this figure but immediately the pressure on the back end is taken away tho
spring brings the plunger back so that the washer L bears upon the shoulder aª
and then the passage is practically sealed inside a'.
Figure 8 is a broken off lower end of the tube A showing one mode of placing
on the cap K by menus of the angular slot & and the stud a' secured in A and
this form is applicable to several of the oilers shown in the previous figures.
Figure 9 shows a different shaped oil can with the cylinder or tube A mounted
in the division and made oil tight. The piston with its rod X and spring T
are momoted therein and the leather or other valve 1 and screw washer U seals
the end of the cylinder A. There are one or two holes a to communicate oil from
the can to the cylinder the inner end being sealed. It will be readily understood
that as the red X is pushed with finger on the oil is ejected into the spout in
aneasured quantities.
The small oiler Figure 10 is very simple in its action having the ordinary
spout. B screwed into the end of A the back end inving a plunger mounted therein
símilar to the previous Figure 7 only the plunger V in this case is open at its inner
end and has mounted therein the wire or tube R with the spring T bearing against
the open bridge with the washer U fastened on the end of R to form a stop.
The plunger is encircled by a ring or packing L and the end al is screwed on A
against a callar a³. The action is as follows:-By pressing the plunger V the oil
is ejected through the spout B where required.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what [
