PROVISIONAL SPECIFICATION.
Improvements in or relating to Vessels such as Oil Cans and
the like.
I, ALEXANDER DONALD, of 17 Wellington Street, Dundee, in the County of
Forfar, North Britain, Photographer, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to improve and simplify the construction of the
valves which control the discharge of the liquid, and the simultaneous influx of air
from and into the vessel respectively; said vessel being of the type in which valves
operated by a push knob are employed. My improvement consists in constructing
the valves and vessel in such a manner that the said valves may be taken out when
worn and repaired or replaced by others, without in any way injuring the vessel.
My improved valves may be applied to oil cans, teapots and the like.
In carrying out my invention, according to one modification as applied to oil cans,
I make the vessel of the usual and most suitable shape and fix the spout-which is
detachable-preferably to the seat of the discharge valve, which is generally near
the bottom of the vessel. At the back of the vessel and near the top is fixed the
air valve seat. Both the discharge and influx valve seats are placed in such
positions relative to one another that their axis are in the same straight line, said
line being usually at an angle to the bottom of the vessel.
Upon a straight spindle is fixed at one end, the discharge valve, the other end of
the spindle being screwed to suit a coupling or nut.
The influx valve is fixed to
another somewhat similar spindle, the one end of which is fitted with the push knob.
Both these valves or their seats may be fitted with cushions of leather or other
suitable material. These two spindles are coupled together when the valves are in
position, by means of the before mentioned coupling or equivalent device. Springs
are employed to press the valves against their respective seats, and are preferably
spiral and placed upon the spindles. The spindles may have channels cut in them
where they pass the seats, to permit of the free passage of the fluid. Other
equivalent devices may be employed to permit of the passage of the fluid.

Improvements in or relating to Vessels such as Oil Cans and
the like.
I, ALEXANDER DONALD, of 17 Wellington Street, Dundee, in the County of
Forfar, North Britain, Photographer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of my invention is to improve and simplify the construction of the
valves which control the discharge of the liquid, and the simultaneous influx of air
from and into the vessel respectively, said vessel being of the type in which valves
operated by a push knob are employed. My improvement consists in constructing

My improved valves may be applied to oil cans, teapots and the like.
The accompanying sheet of explanatory drawings illustrates the method of
carrying out my invention, according to one modification as applied to oil cans.
Figure 1. represents a longitudinal section of the oil can,
Figure 2. a section at A. A. of the discharge or oil valve,
Figure 3. a section at B. B. of the air valve,
Figure 4. a plan of the screw valve, and
Figures 5. and 6. a section at C. C. and a section at D. D. respectively of an
alternative valve or door to take the place of the aforesaid screw valve.
In these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.

I make the vessel 7. of the usual and most suitable shape and fix the spout 8.-
which is detachable-preferably to the seat of the discharge valve, which is
generally near the bottom of the vessel. In the said discharge valve, 9. is the seat,
and 10. the valve, 11. being a washer of leather or other suitable material.
the end socket of the spout 8. and is held in position by means of a bayonet joint,
of which 13. is the stud and 14. the guide slot in which the stud 13. moves.
a washer of leather or other suitable material and is used to keep the oil from
leaking past. 16. and 17. are the passages through which the oil flows when the
valve 10. is lifted off its seat. At the back of the vessel and near the top is fixed
the air valve seat 18. Both the discharge and influx or air valve seats are placed
in such positions relative to one another that their axis are preferably in the same
straight line, said line being usually at an angle to the bottom of the vessel. Upon
a straight spindle 19. is fixed at one end, the discharge valve 10., the other end of
the spindle being screwed to suit a coupling or nut 20. The influx valve 21. is fixed
to another somewhat similar spindle 22., the one end of which is fitted with the push
knob 23. 24. is a washer of leather or other suitable material, and 25. is the air
channel. These two spindles 19. and 22. are coupled together when the valves are
in position, by means of the before mentioned coupling 20. or equivalent device.
Springs 26. and 27. are employed to press the valves against their respective seats,
and are preferably spiral and placed upon the spindles. 28. is a screw valve, 29. is
the hinged door in which it is supported, and 30. is the valve seat preferably fixed
to the oil can. Figures 5. and 6. illustrate an equivalent device to the screw valve,
in which 31. is the seat fixed to the oil can, 32. is the valve or door, 33. a stud and
34. the guide slot, the combination forming a bayonet joint, 35. being the washer
which keeps the oil from passing. When it is required to use the oil can; the
valve 28. is screwed up until its lower side clears the top of the can, the hinged
door 29. is then turned in the direction of the arrow and access is obtained to the
interior of the can. When the said can is filled with oil the door is replaced and
the valve closed, the can being then ready for use. When it is required to pour oil
the push knob 23. is pressed thus taking the valves 10. and 21. off their seats
and permitting air to flow through the channel 25. and oil through the channels 16.
and 17.
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) In oil cans and the like, the use of the detachable spout joint and oil valve,
substantially as described.
(2) In oil cans and the like, the use of the influx, or air valve, substantially as
described.
(3) In oil cans and the like, the combination of the detachable spout joint, the
oil valve and the air valve, substantially as and for the purposes set forth.
(4) In oil cans and the like, the general construction combination and arrange-

page_text: ment of parts, substantially as and for the purposes herein set forth, together with
any mere modification or modifications thereof.
