PROVISIONAL SPECIFICATION.
An Improved Self Fitting Cover for Tobacco Pipes.
I, SAMUEL HENRY CROCKER of Fleet Street, London, Engineer do hereby
declare the nature of this invention to be as follows:
My invention has for its object to provide a self fitting perforated cover for
tobacco pipes, constructed on the most economical lines, so as to easily fit the.
varying diameters of the bowls of the tobacco pipe. A most important feature of
I am able to
my invention is the simplicity and economy of construction.
accomplish my invention by two parts only, in the following manner.
One part consists of a disc stamped out to the required diameter provided with
sufficient holes to allow for the proper smoking of the tobacco within the pipe. In
or about the centre of this disc is a larger perforation. I now stamp out a narrow
strip of metal and bend same somewhat after the form of the letter S, provided with
extended arms. This bent strip of metal forming a spring has projecting pieces
passing through the disc near the centre of the same acting as rivets to secure the
curved spring to the disc. The spring portion is attached to the underneath side of
the disc. The metal strip is further formed so as to have 2 small projecting tines
or arms passing through the centre perforation of the disc, and when these two are
moved towards each other, the elongated arms terminating the S shaped spring are
correspondingly withdrawn towards the centre of the disc, and when the small tines
are released, the spring action will extend the elongated arms to their full extent.
The ends of these elongated arms are arranged to press against the inside of the
bowl, and these arms are the means of keeping the disc firmly attached to the bowl.
It will readily be seen that having only 2 parts which are attached together by
rivetting or similar devices to accomplish the whole of my invention, that the same
can be most economically manufactured.
As a modification of my invention 1 may place the S shaped spring upon the top
of the metal disc, allowing the extended arins of the same to project beyond the
circumference of the said disc, and in this case the extended arms are provided with
tines working in slots, and these tines are the mediums for attaching the device to
the interior of the pipe. In this case one or two small projections in the centre of
the S shaped spring act to rivet the same to the disc. The elongated arms and the
curved spring may be turned upwards instead of extending over the edge of the
disc, and when the ends of this curved spring are drawn towards each other,
the cover is released.
I prefer to scollop out the outside of the disc and this disc may be formed in the
blank somewhat larger than is required for the finished diameter, and the scolloped
edges are then turned down all around, when the flat disc stands up upon the top of
the pipe, and side ventilation is obtained.

I SAMUEL HENRY CROCKER of Fleet Street, London, Engineer, 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 for its object to provide a self fitting perforated cover for
tobacco pipes, constructed on the most economical lines, so as to easily fit the
varying diameters of the bowls of the tobacco pipes. A most important feature of
my invention is the. simplicity and economy of construction. I am able to
accomplish my invention by two parts only, in the following manner :-
One part consists of a disc stamped out to the required diameter provided with
sufficient holes to allow for the proper smoking of the tobacco within the pipe. I
now stamp a narrow strip of spring metal and bend it so as to form a curved spring,
with projecting tines or arms passing through the disc near the centre of the same,
or extending on each side. The spring is attached to the underneath side of the
dise by means of small projecting pieces passing through the disc and riveting the
spring in place.
The form of spring I prefer to use is somewhat similar to the letter S, but is
provided with extended arms at the ends, and the arrangement is such, that on
pressing the tines or arms above mentioned towards each other, the elongated arms
terminating the S shaped spring are correspondingly withdrawn towards the centre
of the disc. When the tines are released the spring action will extend the elongated
arms to their full extent. The ends of these clongated arms are arranged to pre-s
against the inside of the bowl, and are the means of keeping the disc firmly attached
to the bowl.
I prefer to scollop out the outside of the disc and this disc may be formed in the
blank somewhat larger than is required for the finished diameter, and the scolloped
edges are then turned down all around, when the disc stands up upon the top of the
pipe, and side ventilation is obtained.
It will readily be seen that having only two parts which are attached together
by riveting or similar device to accomplish the whole of my invention that the same
can be most economically manufactured.
In order that the invention may be more clearly understood, reference is had to the
accompanying sheet of drawings, in which Fig. 1 is an under-side view, Fig. 2a pla i
and Fig. 5 a side elevation of one form of my invention Figs. 4, 5 and 6 are similar
views of a modification and Fig. 7 is a detail view of a part of the device and
Figs. 8 9 and 10 are similar views to Figs. 1, 2, and 3 showing another modification.
Referring to Figs. 1, 2, and 3 A is the disc provided with a perforation a and
permitting of the passage of air, and a further perforation a¹ which serves the same
purpose, and also permits a part of the device hereinafter described to pass
through.
On the under side of the disc a spring B is employed to attach the cover to the
bowl of the pipe. This spring is formed from a flat strip of spring metal, beut as
shown into Sform, but provided with the extensions bat each end projecting in
opposite directions. The spring is fitted to the disc by a small projection at the
middle, passing through the disc and bent over to form the rivet. The arms or
tines C are stamped from the saine piece of spring metal passing through perfora-
tions and projecting for some distance above the plate, so that they can be
conveniently pinched between the fingers when the cover is to be fitted to the pipe.
On pinching these, the spring will be compressed and the extensions & drawn towards
the centre.
.

page_text: In the arrangement shown in Figs. 4 to 7 the spring B₁ is of C shape, and the
sides of the spring itself bear against the inside of the bowl of the pipe. This
spring is not riveted to the disc, but is attached by means of the tines C¹ which
project through the central hole a². These tines are cut with notches c and are of
such a size that they can pass easily through the hole a' at the centre, but when
they spring apart on being released they will engage with the edge of the disc at
the perforation, the disc extending into the notch c. The spring can be immediately
detached from the disc by pressing the tines to the centre and pushing them
through the perforation, as shown in Figs. 8, 9, and 10. The spring B is similar in
general construction to that shown in Figs. 1, 2, and 3, the extensions 6 being
formed in this case with a serrated edge which bears against the bowl of the pipe.
The tines C instead of passing through the perforation in the disc are formed
at the extremity of the extensions 6 and project at the sides of the disc. They
are formed with the slots c¹ into which the spikes or projections c² formed on the
edge of the disc project, being bent over after passing through the slots. These
assist in attaching the parts more securely together.
The edge of the disc instead of being formed blank as shown in the other device
may be formed with the scolloped edges a' which are turned down as shown in
Fig. 10 to make the disc stand up above the top of the pipe, leaving ventilation
openings at the side.
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 an improved detachable pipe cover the combination with a covering plate
or disc, of a spring formed from a flat strip of spring metal, arranged to bear
against the inside of the pipe bowl, provided with tines or arms stamped from the
same strip of metal and adapted to be pressed between the finger and thumb, the
spring being fitted by riveting or otherwise on the underside of the plate,
substantially as described and for the purposes specified.
(2.) In an improved detachable pipe cover the combination with a metal plate or
disc of a strip of spring metal attached to the underside of the disc, and bent to
form an S shaped spring, having projecting arms at the ends, arranged to bear
against the inside of the pipe bowl, and tines adapted to be pressed between the
finger and thumb to withdraw the projecting arms substantially as and for the
purposes specified.
(3.) In an improved detachable pipe cover the combination with a perforated
covering disc or plate of a strip of spring metal fitted on the underside of the disc,
and bent to form an S shaped spring, with projecting arms at the extremities,
arranged to bear against the inside of the pipe bowl, and tines on the end of the
Sshaped spring, passing through perforations in the disc near the centre, and
adapted to be pressed between the finger and thumb, compressing the spring and
withdrawing the projecting arms substantially as and for the purposes specified.
(4.) In an improved detachable pipe cover, the combination with a covering plate
or disc, of a strip of spring metal fitted to the disc bent to form an S shaped
spring, with projecting arms bearing against the inside of the pipe bowl, and tines
at the extremity projecting at the side of the disc, and adapted to be pressed
between the finger and thumb, substantially as and for the purposes specified.
(5.) In an improved detachable pipe cover, consisting of a perforated covering
disc, with means for attaching to the pipe bowl, forming the disc with scolloped
edges bent down so as to support the disc above the top of the bowl, substantially
as described and shown and for the purposes specified.
