Improvements in the method o
other Collapsible Tubes.
I, FRANK REEVES of 34 Bloomsbury Street, London, W.C. Engineer do hereby
declare the nature of this invention to be as follows:-
-
My invention has reference to certain new and useful improvements in artists'
colour tubes and other collapsible tubes, and is designed for the purpose of providing
said tubes with a simple, neat and effective device by means of which the nozzle or
opening thereof may be readily opened or closed.
In my invention, the cap is not detachable from the nozzle of the tube and is there-
fore not liable to become mislaid or lost.
My improvement consists of an undetachable cap which is provided upon its upper
surface with a suitable aperture which is conveniently segmental in shape and which
aperture is made to conform to a corresponding segmental or other opening in the
nozzle of the tube.
Around the circumference of the nozzle I form a nick or groove into which is bent
the lower edge of the cap in such a manner that it can be turned around without
becoming detached.
The periphery of the cap is preferably milled or provided with projections for
turning.
By partially revolving the cap the aperture therein will be caused to coincide with
the aperture in the nozzle thus forming an exit for the contents of the tube. By
partially revolving the cap in the reverse direction the aperture in the nozzle of the
tube will be effectively closed.
The segmental opening in the cap is of double the angular extent of that in the
nozzle and in addition to the latter embraces a portion of the nozzle of the tube which
is made to project through the aperture in the cap and is formed flush with the upper
surface thereof. By this arrangement any accumulation of paint or other matter in
the opening through the cap is prevented.

page_text: An alternative method of carrying out my invention consists in providing the nozzle
of the tube with a shallow cap which is pressed down upon said nozzle by a suitable
spring. The spring aforesaid may consist of a piece of steel or other wire which is
passed over and suitably secured to the top of the cap and having its two extremities
bent downwards and inwards and suitably pivoted into the lower portion or neck of the.
nozzle.
By slightly lifting the cap from off its seat it may be swung to either side, thus
opening the nozzle of the tube.
Another alternative method of effecting my invention consists in forming the nozzle
or upper portion of the tube with a socket in which a ball is free to partially revolve.
Said ball is provided with an aperture which passes centrally & horizontally through
its diameter. By providing said ball with any suitable projection, it may be partially.
revolved in its socket and its horizontal aperture brought coincident with the opening
to the tube thus effecting an egress for the contents of said tube.

page_text: Improvements in the Method of Closing Artists' Color Tubes and
other Collapsible Tubes.
I, FRANK REEVES of 34 Bloomsbury Street, London, W.C. 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 has reference to certain new and useful improvements in artists color
tubes and other collapsible tubes and which improvements are designed for the purpose
of providing said tubes with simple neat and effective devices by means of which the
nozzles or openings thereof may be readily opened or closed.
By my invention the closing device need not be detached from the nozzle of the
tube and is therefore not liable to become mislaid or lost."
I now proceed to describe my said invention reference being had to the accom-
panying drawings and the figures and letters of reference marked thereon similar
letters indicating like parts throughout.
Fig. 1, is a sectional elevation of an artists' color or other collapsible tube closed in
accordance with my invention.
Fig. 2, is a plan top view of Fig. 1.
Fig. 3,
a sectional elevation showing a modified form of my invention.
Figs. 4 and 5, are respectively sectional and transverse sectional elevations showing
alternative forms of my invention.
Figs. 6 to 11, are alternative forms of my invention showing the same open and
closed respectively.
Fig. 12, is a sectional elevation showing a modified form of my invention as
illustrated in Fig. 3.
Fig. 13, is a sectional elevation of a modified form of my invention showing the
nozzle open.
Figs. 14 & 15 are sectional elevations of an alternative form of my invention, showing
the same respectively open and closed.
Fig. 16, is a modification of that form of my invention shown in Figs. 14 and 15.
In the drawings A represents the color or other collapsible tubes and in Figs. 1,
and 2, I have shown said tube partially closed at its upper end as shown at a.
Around the circumference of the tube A is formed the groove a into which the
flanges 6 of the cap B, may be bent as shown at 6', said cap B is formed with a
segmental or other aperture B', of the same size and adapted when desired to coincide
with the segmental or other aperture A¹ formed in the upper part of the tube A.
The periphery of the cap B is preferably milled or otherwise roughened in order
that it may be more readily turned by the fingers for the purpose of opening or closing
the tube which opening is effected by turning the cap B until the aperture B' coincides
with the aperture A¹-a further turning of the cap B will effectively close the
tube.

page_text: A
In Fig. 3, I have shown the tube A, provided with a cap C, having a tenon c.
spring C, made of wire may be made to pass through an aperture in the tenon c, and
to pivot in the sides of the case A, as shown at c¹. When it is desired to open the tube
the cap C, may be lifted and swung to one side by means of the tenon c, as will be
understood.
In Figs. 4 and 5, the nozzles of the tube A, is shown formed with side lugs d, over
which is adapted to slide a metal cap D, formed with flanges d¹. In order to gain
access to the tube A, said cap may be slid to one side until the aperture in the
nozzle is opened.
In Figs. 6 and 7, the nozzle of the tube A, is shown fitted with a stopper E, which
may be formed out of a piece of rod suitably shaped and formed with a groove e.
In this construction access may be.had to the contents of the tube through the
groove e when the stopper is drawn out as shown in Fig. 6; the tube being closed
when the stopper is home as shown in Fig. 7.
In Figs. 8 and 9, I have shown the nozzle of the tube formed with a round
knob over which is fitted a partly globular piece of metal F, formed with a tenon
piece f.
By means of the tenon piece f the piece of metal F, may be swung to one side
to open the nozzle Fig. 8, and into a vertical position Fig. 9; to close the nozzle.
In Figs. 10 and 11, the nozzle of the tube A is shown formed with a screw
thread g, over which is fitted the screw cap G, which is partially cut away at gl
as shown. By a slight turn of the cap G, the aperture in the nozzle of the tube A,
will be uncovered Fig. 10, or covered as shown in Fig. 11.
Fig. 12, shows a modification of my invention as shown in Fig. 3, but in this form
I employ a metal or other ball H, suitably attached to wire springs h, pivoted to
the tube A at 7. The aperture in the nozzle may be uncovered by lifting the ball
and swinging it to one side as will be understood.
Fig. 13; shows the nozzle of the tube A, closed in with the exception of a small
aperture J, a metal or other ball J, having through it an aperture ; is pivoted
within the tube A, upon a pin formed with a knob j'. By means of the knob j¹
the ball J, may be revolved until the aperture j coincides with the aperture J, and
the aperture of the tube A, is thereby opened.
Figs. 14 and 15; show the tubo A, formed to receive a metal or other ball K, having
a tenon-piece k, and an aperture k¹³. When it is desired to open the tube A, the metal
or other ball K is swung to one side as shown in Fig. 15, and the tube is thereby
opened.
Fig. 16, shows a modified form of my invention as shown in Figs. 14 and 15,-the
manner of opening the tube being the same.
In this modification however I contract the nozzle at L, and form therein a slot 1,
to receive the tenon-piece L¹, when the tube is open as shown.
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 :-
Artists color tubes and other collapsible tubes, fitted with the closing devices
herein before described and illustrated in the drawings all substantially as and for the
purposes hereinbefore set forth.
