PROVISIONAL SPECIFICATION.
Improvements in Cocks or Taps.
I, SAMUEL INGHAM MERRILL of 415, South Main Street, in the City and
County of Los Angeles, State of California, United States of America, Oil
Merchant, do hereby declare the nature of this invention to be as follows:-
My invention relates to cocks or taps more especially designed for oil cans but
applicable to other liquid-holding vessels in which the spout of the cock or tap
when the latter is closed shuts up under cover of the vessel and when open projects
downwards and outwards from the same.
The recess of chamber in the front portion of the can or vessel may either be a
component part of a new can or vessel or in case of applying the invention to an
old can not so provided the same may be done by simply cutting out a portion of
the body of the can or vessel adapted to receive the chamber within it and then
inserting said chamber within it and securing it to the body by outer flanges and
rivets or any suitable fastenings.
The chamber presents an open front on the exterior of the can and should be so
made as to hold the cock or tap within it and so that, when the latter is closed, its
spout will occupy a raised position within it and be fully protected both during
transportation of the can or vessel and at other times and so that, when the spout
is turned downwards and outwards, flow of the oil or liquid out of the can or vessel
is established through the cock, the spout forming a handle by which to open and
close the cock. The spout is constructed at its outer end to also form a nozzle.
The body of the cock consists of a tapering inner barrel arranged crosswise within
the chamber and an outer tapering sleeve closely fitting over said barrel and having
the spout connected with or forming part of it. The one end of the barrel which
is firmly secured to the one side of the chamber has free communication with the
interior of the can or vessel to admit of the passage of the liquid into it, but the
opposite end of said barrel is closed. It also is provided with a front side aperture
or outlet for passage of the liquid through the cock when the spout is turned
downwards and outwards so as to bring an outlet aperture in its inner end in line
with the outlet of the barrel.
As it is desirable that the cock should not work too freely, I provide a spring or
elastic washer which loosely encircles the inner and smaller closed end of the barrel
and presses against the inner smaller end of the closely-fitting sleeve. This serves
to hold the cock closed and tight and produces friction enough to hold the spout
in its raised position within the chamber.
Dated this 19th day of April 1892.

COMPLETE SPECIFICATION.
Improvements in Cocks or Taps.
I, SAMUEL INGHAM MERRILL of 415, South Main Street, in the City and County
of Los Angeles, State of California, United States of America, Oil Merchant,
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
5 statement :-
My invention relates to cocks or taps, more especially designed for oil cans but

page_text: mg e same substantially as nereimiter resided and mor
particularly pointed out in the claim.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 represents a front elevation, of a can or vessel in part, with tap
applied and as closed or raised up within the chamber or recess in the body of
the can:
Figure 2 is a partly sectional side elevation of the same, upon the line 2-2 in
Figure 3 looking in the direction of the arrows in the latter; and
Figure 3 is a partly sectional elevation upon the line 3-3 in Figure 2, looking
in the direction of the arrows in Figure 2.
A indicates an oil or other liquid-holding can or vessel having a recess or
chamber B within the front portion or one side of its body. This chamber with
which the tap is connected and to which it is securely attached, may either be a
component part of a new can or vessel or in case of applying the invention to an
old can, not so provided, the same may be done by simply cutting out a portion of
the body of the can or vessel adapted to receive the chamber and then inserting
said chamber within it and securing it to the body by outer flanges and rivets or
any suitable fastenings. Thus the invention may be said to require no special
construction of can or vessel but is applicable to almost any old form. The
chamber B presents an open front on the exterior of the can and should be made of
sufficient capacity and height to hold the tap within it and so that when the tap is
closed its lever spout C will occupy a raised position within it, out of harm's way,
and be fully protected both during transportation of the can or vessel and at other
times and so that when the lever spout C is turned downward and outward as
represented by dotted lines in Figure 2, flow of the oil or liquid out of the can or
vessel is established through the tap, the lever spout C forming a handle by which
to open and close the tap. Said lever spout is constructed at its outer end to also
formi a nozzle. The body of the tap consists of a tapering inner barrel D arranged
'crosswise within the chamber B and an outer tapering sleeve E closely fitting over
said barrel and having the lever spout C connected with or forming part of it.
The one end of the barrel D which is firmly secured to the one side of the
chamber B is left open and has free communication with the interior of the can or
vessel to adimit the liquid into it, but the opposite end of said barrel is closed. The
barrel D is also provided with a front side aperture or outlet c for the passage of
the liquid out through the tap when the lever spout C is turned downward and
outward so as to bring an outlet aperture d in its inner end in line with the outlet c
of the barrel. As it is desirable that the tap should not work too freely but should
have a certain tension or resistance given it, I arrange a spring or elastic washer f
which is made. to loosely encircle the inner and smaller closed end of the barrel Ď
and to press against the inner smaller end of the closely fitting sleeve E. This
serves to hold the tap closed and tight and produces friction enough to hold the
lever spout C in its raised position within the chamber E.
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:
The combination of the chamber B open at its front and the tapering tubular
barrel D having its large end opening through the lower end of one side wall of
chamber B closed at its opposite end and provided between its ends with a lateral
opening the outer tapering sleeve E upon the barrel D and having a lateral
opening d to register with opening e a spiral spring on the smaller end of barrel D

page_text: and bearing at one end against the smaller end of sleeve E and bearing at its
opposite end on the adjacent side wall of the chamber B and the lever spout C
secured to sleeve E, over its opening c, substantially as set forth.
