Improvements in and relating to Covers for Tobacco Pipes.
I, ARCHIBALD ALLAN PERCY of 38 Sauchiehall Street Glasgow, Manufacturer,
lo hereby declare the nature of this invention to be as follows:-
This invention relates to covers for tobacco pipes and it has for its object to
improve their construction.
In the Specification of my prior Patent No. 715 of 1893 I have described and
shown pipe covers having holding grips which can be maintained in the adjusted
position within a pipe bowl by means of one or more springs.
My present invention is a further devolpment of my said prior invention.
The cover may be made in various ways and may or may not have, as desired,
pushers for pushing down or compressing the tobacco combined with it.
Under one arrangement I make the cover of a disc or plate, preferably provided
with ventilating openings or slots, to which is secured, at the underside, a helical
volute or like spring. One end of this spring is rigidly secured to the cover whilst
the other is fitted to a pivot or pin which passes or may pass up through the disc or
plate and is capable of being turned, or moved, preferably by means of a small
handle or the like.
The arrangement is such that when the handle or pin is turned or moved the
spring which constitutes the holder or grip of the cover can be compressed or
expanded on a horizontal plane so as to fit into various diameters of pipe bowls..
Instead of having a helical or volute spring, an S or other suitable form of spring
capable of being readily compressed and expanded may be used.
In some cases the spring may have pieces or flanges on it, or connected to it,
which constitute grips or holders.
In some cases where the spring is rigidly secured at the centre and is free at its
outer end, the pin at this end may pass up through a guide slot in the cover.
The cover may be so made as to combine in one a pusher and cover. In this case the
helical volute or like spring has on its outer edge, or helix, a number of projecting
lugs or a rim which, when the cover is fitted in place, rests on the upper edge of the
pipe bowl.
The central end of the helical or volute spring has a pusher plate attached to it
on the underside and a button, plate, or knob or equivalent at the upper side for
pressure by the finger.
A cover plate or disc may or may not be used with the spring as desired, if a
cover plate is used it is made with a central hole for the passage of the finger.
In order to keep the spring in proper shape its outer end may have a projection
or part on it which fits into and works in a slot or opening in the next helix.
A pipe lighter consisting of a cylindrical shaped piece bored with a number of
holes may be combined with the spring pusher or cover. With this arrangement
the pipe can be lighted when the cover is on.
The spring cover may be adapted to the bowl by merely compressing it or by
compressing the spring through the medium of pins, plates or lugs or bars.
The helical or volute spring and its plates may be combined as a pusher only,
with any form of suitable cover having a central opening for the passage of the
finger.
The spring pusher may be made with handles, arms or lugs for working it up and.
down. These handles may have a spring action and be hinged.

page_text: The outer edge of the spring may be serrated to afford a better hold whe
inserted in the pipe powl.
The button at top of the pusher may have arms, wings, projections, or a mille
edge on it for coiling the spring and adjusting it to the pipe."
The pusher plate may consist of or be covered by, asbestos porcelain or other hea
resisting material.
I am aware that pushers have been heretofore used with spiral springs.

I, ARCHIBALD ALLAN PERCY, of 38 Sauchiehall Street, Glasgow, Manufacturer,
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 :-
'
This invention relates to covers for tobacco pipes and it has for its object to
improve their construction.
In the Specification of my prior Patent No. 7.15 of 1893 'I have described and
shown pipe covers having holding grips which can be maintained in the adjusted
position within a pipe bowl by means of one or more springs.
My present invention is a further development of my said prior invention.
The cover may be made 'in various ways and may or may not have, as desired,
pushers for pushing down or compressing the tobacco combined with it.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a side elevation and Fig. 2 a plan of one form of the cover.
Fig. 3 is a plan and Fig. 4 a side elevation of another slightly different form of
the cover.
Fig. 5 is a sectional plan and Fig. 6 a cross section, showing the spring in full, of.
another form of the cover.
Fig. 7 is a side elevation, Fig. 8 a plan, and 'Fig. 9 a vertical section of a cover
and pusher.
Fig. 10 is a full plan, Fig. 11 a sectional plan, and Fig. 12 a side view of another
form of combined cover and pusher.
Fig. 13 is a plan and Fig. 14 a vertical cross section of a combined spring grip
cover and pusher.
Fig. 15 is a vertical cross section of a'hélical spring cover and pusher.
Fig. 16 is a side view of a pusher.
Fig. 17 is a plan and Fig. 18 a section of a pipe lighter.
Referring to the drawings whereon the same reference letters indicate the same
or similar parts.
The tobacco pipe cover A shown at Figs. 1 and 2 consists of a disc or plate a,
provided with ventilating openings b, and to the underside of which a helical or
volute spring such as c is secured. The end of the outer helix is secured rigidly to
the cover at c' whilst the inner end is secured to a revoluble pivot or pin d passed
through disc a and provided with a milled knob or wings d' (Fig. 1^), at its upper
end, for turning it.
Instead of this arrangement the cover B shown at Figs. 3
In this case the spring e is secured rigidly to the cover a at its
outer helix, which has free movement, is provided with a stud

working in a guide

page_text: lot fcut in cover plate a. For facility in catching the cover a small projection g
at the opposite side to the stud f can be secured to the cover.
The arrangement Figs. 1 to 4 is such that when the knob d (Fig. 1) is turned or
the stud f (Fig. 3) is moved along the slot fl, the spring c, which constitutes the
older or grip of the cover can be compressed or reduced in diameter on a horizontal
plane, to a greater or smaller extent so as to fit into pipe bowls of different internal
diameters. Of course, when the spring is freed, it expands or tends to expand to its
full extent so as to tightly grip in the pipe bowl.
Figs. 5 and 6 show a cover C made of a plate a'i having ventilating openings 6 in
it and a cross piece, or a plate, a³. Between the parts a', a³ an S or equivalent
shaped spring is fitted by solder or other suitable attachment. This spring
which has prongs or grips j, j for catching in the interior of the pipe bowl, secured
to it, is capable of being compressed from each side by means of the sliding
pushes k, k. These prongs j, 72 pass down through guide slots 1, 1 cut in the

to compress the spring and grips by means of the pushes k, k¹.
part a².
The cover D shown at Figs. 7, 8 and 9 combines in one a helical spring cover
and a pusher or "stopper" for compressing the tobacco in the pipe bowl. The
helical spring c has, formed on or soldered to its outer helix, a number of projecting
lugs m, or their equivalent, which, when the cover is fitted in place, rest on the
upper edge of the pipe bowl. The central end or helix has a "stopper" plate
attached to its underside and a button o or equivalent, to its upper side for pressure
by the finger. The view Fig. 9 shows the stopper as it appears when pressed down
by the finger. A cover plate such as g Fig. 15 can be used with the spring in lieu
of the lugs m.

In order to keep the spring in proper shape the end of its outer helix have
a slot in it which catches and works on a projection r¹ on the next inner helix, as
shown at Fig. 7 where c' is the first or outer helix and c³ the second one.
This spring cover can be adapted to the bowl by merely compressing it or by
compressing the spring c through the medium of pins, plates, or lugs or bars.
Figs. 10, 11 and 12 show a cover E formed of two plates a', a', having central
holes in them and provided with plate springs p, pl actuated by pushes k, k'. The
pushes have grips j, j as at Fig. 6. Secured in the centre of the cover is a small
helical spring pusher or stopper consisting of the pusher plate n and spring s.
spring s is shown extended at Fig. 12 as it appears when compressing the tobacco
in the pipe bowl.

The
The cover F shown at Figs. 13 and 14 consists of a cover such as that at
Figs. 10, 11, and 12 but having combined with it a
"stopper t provided with
hinged arms t1, t2, as specified in the Specification of my prior Patent No. 23,234
of 1893. This stopper is used in lieu of the stopper s, n Figs. 10, 11 and 12.
Fig. 13 shows the stopper up and the arms t¹, * spread down on top of the
cover plate a'. Fig. 14 shows the stopper as it appears when pushing down the
tobacco.
Fig. 16 is a side view of the stopper ₺ Fig. 14.
Fig. 15 shows a cover G, similar to D, Figs. 7, 8 and 9, but having a cover
plate q, provided with a central hole q'. The spring c has a pusher plate n and a
button o provided with hinged arms t¹, t.
A pipe lighter consisting of a concave piece u bored with a number of holes u¹
may be combined with the spring pusher or cover as shown at Figs. 17 and 18.
With this arrangement the pipe can be lighted when the cover is on. The pusher
plate n is also perforated.
The arms t, t can have a spring action as set forth in my prior Specification
No. 23,2343.
The button at top of the pusher may have arms, wings, projections, or a milled
edge on it for coiling the spring and adjusting it to the pipe.
The pusher plate may consist of or be covered by asbestos, porcelain or other
heating resisting material

page_text: I am aware that pushers combined with spiral springs have heretofore been used
and I make no claim for such spiral spring pushers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I consider novel and desire to claim is :-
1. A cover for tobacco pipes consisting of or having combined with it a helical
or volute spring whereby it can be adapted to fit various diameters of pipe bowls,
substantially as herein before set forth.
2. The combination with a cover for tobacco pipes of a helical or volute spring
pusher or stopper substantially as hereinbefore described with reference to the
drawings annexed.
3. The several constructions of pipe cover substantially as hereinbefore described
and shown on the drawings annexed.
Dated this 6th day of June 1895.
