PROVISIONAL SPECIFICATION.
An Improved Tobacco Pipe Cap or Cover.
I, JOHN THEODORE KAMCKE, 73 Fitzwilliam Place, Belfast, Linen Merchant,
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved cover or cap for tobacco pipe bowls, to
protect the contents in windy or rainy weather. The cap consists of a thin metal
disc a little larger than the top of the bowl and attached to the latter by a device
which allows it to be adjusted to any size of bowl. This device consists of two
pins one fixed at one side of the plate and projecting a little below, and the other
passing through a slot in the plate, both having small knobs at the top, allowing
the second to be moved to and fro in the slot. A spring of bow shape is attached
to the top of the cap, bearing against the second pin and pressing it to the outer
end of the slot. To fix on the bowl of the pipe, the knobs are pressed together
moving the second pin to the rear of the slot and allowing the cap to be placed on
the bowl with the two pins inside. On releasing the pins the spring will force
them apart, causing them to bear against or clip the bowl and firmly attach the
cover.

An Improved Tobacco Pipe Cap or Cover.
I JOHN THEODORE KAMCKE of 73 Fitzwilliam Place Belfast, Linen 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
statement :-
My invention relates to an improved cap or cover for the bowls of tobacco pipes
which protects the contents in windy or rainy weather.
The cap consists of a thin perforated metal disc extending a little over the inner
edge of the pipe bowl intended to be covered and is attached to it by a device
which is automatically adjustable to the size of such bowl.
;
This device consists of two pins or narrow curved plates or one of each near to
the edge of the disc and projecting a little below it so as to catch the inner side of
the bowl at diametrically opposite points, one of such pins or curved plates being
fixed in the disc and the opposite one having a stud at the top which passes through
a radial slot in the disc and holds it in position, while allowing it to move freely to
and fro in the slot. Or, instead of this second pin or curved plate, I employ a
radial slotted plate arranged with a flange at the outer end thereof, similarly held
in position by a stud near the flange and guided by an additional stud, in the
centre of the disc, passing through the slot of the radial plate and having, if
desired, a ring above the disc by which it may be conveniently lifted from the pipe
bowl.
The pins or studs may be furnished with knobs on their ends above the top of
the disc and the faces of the pins or curved plates or flanges are preferably furrowed
or toothed for gripping.

page_text: A double bow or oval shaped spring or like spring is attached to the top of the
disc by the central or fixed eccentric pin or stud or other convenient and obvious
fulcrum so as to bear against the secondly described pin or the stud on the curved
or radial plate and press it to the outer end of the slot in the disc and against the
inner side of the pipe bowl.
To fix the cap on the bowl of the pipe the knobs on the pins or studs are pressed
together moving the secondly described pin or stud and curved plate or flange
towards the centre of the disc and allowing the cap to be placed on the bowl with
the two pins or pin and plate or flange projecting down inside of it; or, more
simply, the secondly described pin, curved plate or flange may be inserted by the
side of the bowl and the disc pressed against it until the stationary pin comes over
the top on the opposite side and can be pressed down into the bowl.
On releasing the knobs or knob or otherwise withdrawing the pressure, the
spring will force the two pins or the pin and curved plate or flange apart causing
them to bear against or clip the bowl and firmly attach the cover.
I may connect with the metal disc, by the central stud, a smaller metal disc
provided with perforations corresponding with the perforations on the larger disc
and capable of being rotated on the central stud so as to close the perforations in
the larger disc at pleasure.
And in order that my said invention may be more fully understood I shall now
proceed to refer to the drawings on the sheet hereunto attached the same letters of
reference indicating the same or corresponding parts thereof.
Fig. I is a top view of the slotted and perforated disc, shewing the knob of a
stationary pin near the edge thereof at one side but without any of the other parts
of my device.
Fig. II is a similar view of the same parts; also shewing the head or knob of a
moveable stud diametrically opposite the other knob, a double bow shaped spring
baving a central stud for its fulcrum and passing round the moveable stud which is
attached to a flanged plate underneath, as shewn by dotted lines.
Fig. III is a sectional view of the cap in elevation shewing the same parts as in
Fig. II and also a ring attached to a central stud or staple.
Fig. IV is a separate plan of a double bow shaped spring.
Figs. V and VI are a separate elevation and plan respectively of a flanged and
slotted radial plate with headed or knobbed stud to pass through the slotted
disc and
Fig. VII is a view of the furrowed or toothed face of the curved plate or of the
flange shewn in Figs. V and VI.
a is the thin metal disc having the slot, a', to provide for the adjustment of the
cap and the perforations, a², a², to produce combustion. b is the fixed or stationary
pin. c is a double bow shaped spring attached by loops to the centre stud or
staple, d, and the moveable pin or stud, e. f is a radial plate with the flange, f¹³,
at its outer end and a slot, f2, extending towards the opposite end and having the
central stud or staple, d, passing through it and held by a washer or plate, g,
underneath and is a ring above the top of the disc and attached to it by the
stud or staple, d.
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 I do not
claim as of my invention or the exclusive use of a disc, spring, pins, plates or studs
separately nor any of the separate mechanical parts which I employ in the
construction of my improved automatically adjustable tobacco pipe cap or cover
but that what I claim is
1. The manufacture and use, as a cover for the bowls of tobacco pipes, of a
slotted disc arranged with a fixed or stationary pin and a moveable pin or curved
or flanged plate and an external or top spring substantially in the manner and for
the purposes hereinbefore described and shewn in the drawings hereunto annexed.
2. The combination and arrangement of parts constituting my automatically

page_text: adjustable tobacco pipe cap or cover constructed and employed substantially in the
manner and for the purposes hereinbefore described and illustrated upon the sheet
of drawings hereunto annexed.
