page_text: LETTERS PATENT to Adolph Strauss, of 26, Basinghall Street, in the City of
London, Pipe Merchant, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OF COVERS FOR PIPES USED FOR SMOKING."
Sealed the 2nd July 1878, and dated the 8th January 1878.
PROVISIONAL SPECIFICATION left by the said Adolph Strauss at the Office
of the Commissioners of Patents on the 8th January 1878.

SMOKING."
FOR
This Invention relates to improvements in the construction of covers for pipes
used for smoking, and consists in fitting to a rim attached to the pipe bowl a series
of plates pinned loosely upon the top edge or face thereof.
The plates have curved or straight slots in them into which pins projecting
from the under face of a sliding ferrule or top rim are caused to engage.
The sliding ferrule is capable of being turned in a circular direction, so that the
pins may push out the plates, and cover or nearly cover the tobacco that is within
the bowl. A reverse movement of the sliding ferrul causes the pins to draw the
plates inwards and under the rim, so that the cover appears flush with the inner
surface of the bowl.
The sliding ferrule is limited in its action by a stud.

the said Adolph Strauss in the Great Seal Patent Office on the 6th July

ADOLPH STRAUSS, of 26, Basinghall Street, in the City of London, Pipe Mer-
chant. "IMPROVEMENTS IN THE CONSTRUCTION OF COVERS FOR PIPES USED FOR
SMOKING."
This Invention relates to improvements in the construction of covers for pipes
used for smoking, and consists in fitting to a rim attached to the pipe bowl
or to the bowl itself a series of plates pinned loosely upon the top edge or face
thereof.
The plates have curved or straight slots or pin holes in them, into which pins
projecting from the under face of a sliding ferrule or top rim are caused to engage.
The sliding ferrule, which is arranged over the plates, is capable of being turned
in a circular direction, so that the pins attached to the ferrule may push out the
plates, and cover or nearly cover the tobacco that is within the bowl. A reverse
movement of the sliding ferrule causes the pins to draw the plates inwards and
under the rim, so that the cover appears flush with the inner surface of the
bowl.
The sliding ferrule is limited in its action by a stud.
The Invention will be clearly understood by reference to the annexed Drawings,
in which in Figure 1 a plan view, and Figure 2 a part sectional view, the cover
composed of a series of plates or wings a, a, is shown. These plates or wings a, a,
are each passed loosely over pins b, b, attached to the rim c.
d is the sliding ferrule or top cap from the under face of which other pins e, e,
project to engage into holes f, one of which is formed in each of the plates a as in
the separate view, Figure 3. Each of the holes f may be slotted, so that the pin e
which takes therein may ride against the edges of the slots when the sliding ferrule
or top rim d is moved round in a circular direction, and the plates a, a, be thereby
pushed from under the top cap into the position shown by dotted lines in Figure 1,
whereby they form a cover to the tobacco that is within the bowl g. By a reverse
circular movement of the sliding ferrule the whole of the plates or wings a, a, are
drawn back under the sliding ferrule, as to be between it and the rim c, thereby
leaving the opening of the bowl perfectly clear for the insertion of tobacco.
In the foregoing Figures I have shown seven plates or wings a, a, as forming the
moveable cover to a pipe bowl, but any other number of plates may be used as
found desirable.
In Figure 5 I have shown six of such plates; and instead of slotting them as in
the previous Figures, I arrange a hole to the rear of the pivot hole, as in the detached
view, Figure 6, for the pin e of the sliding ferrule or top cap to engage in.
Each plate a in this as in the previous Figures turn upon the pivot pins b, b, and
are forced outwards in a circular direction, as in dotted lines, to serve as a cover to
the tobacco as before explained.
The sliding ferrule is limited in its movements to and fro by the stud h, which
moves in the slot of the outer ferrule, or of the inner ferrule or rim.
The rim may be dispensed with, if found desirable, and then the pivot pins would
be fixed in the top edge of the pipe bowl, especially, with wooden pipes into which
the pins could be secured with facility, the sliding ferrule being alone used for
shifting the position of the plates or wings a, a, as before explained.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim, the improvements in covers for pipe

page_text: bowls, consisting of plates or wings a, a, moveable in and out by a sliding ferrule or
cap, as described, and substantially as shown in the annexed Drawings.
In witness whereof, I, the said Adolph Strauss, have hereunto set my hand
and seal, this Fifth day of July, in the year of our Lord One thousand
eight hundred and seventy-eight.
ADOLPH STRAUSS. (L.S.)
