Year: 1880

page_text: LETTERS PATENT to Christian Reimers, of the Firm of Zerkowsky and
Reimers, of Finsbury Square, in the City of London, Manufacturers, for an
Invention of "A NEW OR IMPROVED WIND-GUARD OR DRAFT-PROTECTOR
FOR OIL LAMPS."
PROVISIONAL SPECIFICATION left by the said Christian Reimers at the
Office of the Commissioners of Patents on the 9th April 1880.
CHRISTIAN REIMERS, of the Firm of Zerkowsky and Reimers, of Finsbury Square,
in the City of London, Manufacturers. "A NEW OR IMPROVED WIND-GUARD OR
DRAFT-PROTECTOR FOR OIL LAMPS."
My Invention relates to a new or improved wind-guard or draft-protector for oil
lamps, the object being to bring the guard or protector into action on the lamp
being taken up, and thus protect the flame from being extinguished while the lamp
is being carried about, also to cause such protector or guard to be restored to its
normal position on the lamp being set down or replaced.
My improved wind guard or draft protector consists of a cylindrical or other
suitably shaped casing, shell, or jacket, provided with a handle, and surrounding
the lamp for any suitable portion of its length. At its lower extremity this guard
or protector is provided with an internal flange, or with inwardly projecting pieces,
which on the protector or guard being raised abut against and form a seat for a
collar, rim, or ring on the lamp, and as the protector or guard now extends above
and surrounds the burner the lamp can be carried from place to place without fear
of its flame being extinguished. The action of setting down the lamp causes the
guard or protector to be restored to its normal position.
The lower portion of the guard or protector may be of metal, and its upper
portion of glass, china, or other suitable transparent or translucent material, so that
besides forming a wind-guard or draft-protector, it can at the same time answer
the purpose of a shado, chimney, or globe. Or the guard or protector may be made
entirely of one material,
In another arrangement or modification the guard or protector is provided with
a bayonet slot which engages in a stud or pin on the lamp so that the said guard or
protector when raised may be retained in place at pleasure; and in some cases the
guard or protector may be raised and lowered by means of a lever or other
equivalent mechanical contrivance.

CHRISTIAN REIMERS, of the Firm of Zerkowsky and Reimers, of Finsbury Square,
in the City of London, Manufacturers. "A NEW OR IMPROVED WIND-GUARD OR
DRAFT PROTECTOR FOR OIL LAMPS."
My Invention relates_to_a_new_or improved wind-guard or draft protector for oil
lamps, and has for object to bring the said guard or protector into action on the
lamp being taken up, and thus protect the flame being extinguished while the lamp
is carried about, and to cause such protector or guard to be restored to its normal
position on the lamp being set down or replaced.
My improved wind-guard or draft protector consists of a cylindrical or other
suitably shaped casing, shell, or jacket which surrounds the lamp for any desired
portion of its height, and which is furnished with a handle. This wind guard or
draft protector is provided at its lower extremity with an internal rim or flange, or
with inwardly projecting pieces, which on the protector or guard being raised abut
against and form a seat for a collar, rim, or ring on the lamp, and as the protector
or guard when raised extends above and surrounds the burner the lamp can be
-carried-from-place-to-place-without fear of its flame being extinguished. The action
of setting down the lamp causes the guard or protector to be restored to its normal
position.
The lower portion of the guard or protector may be made of metal, and its upper
portion of glass, china, or other suitable transparent or translucent material, so that
besides forming a wind-guard or draft protector it can at the same time answer the
purpose of a shade, chimney, or globe. Or the guard or protector may be made
entirely of one material if preferred.
In another arrangement or modification the guard or protector is provided with
a bayonet slot or slots which engage in a stud or studs on the lamp so that the
said guard or protector when raised may be retained in place at pleasure; or the
bayonet slots may be on the lamp and the studs on the guard or protector; and
in some cases the guard or protector may be raised and lowered by means of a
lever or other like mechanical contrivance.
In order that my Invention may be more fully understood and readily carried
into effect, I proceed, aided by the accompanying Drawings, to describe the same.
The Drawings represent a hand lamp to which my new or improved wind guard
or draft-protector is applied.
Figure 1 is a front elevation of same, shewing the wind-guard or draft protector
in its normal position, that is to say, in its lowered position, and Figure 2 is a front
elevation shewing the same raised or in action; Fig. 3 is a plan.
A is the lamp, and B the new or improved wind guard or draft protector
hereinafter, to avoid repetition, called wind-guard only. This wind-guard, which
may be of any suitable shape, is provided at its lowermost extremity with an
internal flange b which abuts against and forms a seat for a collar or ring a which
is secured to the body of the lamp at its upper part. This wind-guard is also
provided with a handle C by means of which it is brought into action.
The wind guard consists of a circular metal socket b*, into which a tubular or
cylindrical piece a* of glass, china, or other transparent or translucent material is
fitted, and which rests on the flange b.
The working is as follows:-The wind-guard is raised by means of its handle C
until it extends above and surrounds the flame sufficiently, when it is stopped at
the desired height by the flange b abutting against the collar or ring a on the lamp.
This collar or ring forming, as before stated, a seat for the lamp to rest on the lamp
can be carried from place to place without fear of its flame being extinguished by

page_text: drafts or gusts of wind. On the lamp being restored to place and the hand
withdrawn from the handle the wind-guard will, by reason of its own gravity,
immediately return to its normal position.
Figure 4 shews the arrangement by which the wind-guard after being raised can
be retained in place, and it consists in forming the collar or ring a on the lamp
with three bayonet alots c placed equidistantly from one another, and providing tho
wind-guard at its lower extremity with three equidistant studs d' corresponding to
the openings of the slots. When the wind guard is raised it has only to be turned
to the right or left, according to the arrangement of the slots, when the studs will
pass into the slots and thereby retain it in its raised position. In this arrangement
the glass or china portion a* of the wind guard is held in a recess or lip 6ª
contrived in the upper portion of the metal socket bx.
Figure 5 is an elevation, and Figure 6 a plan of an arrangement I adopt for
raising and lowering the wind-guard by means of a lever. D is a forked lever
having its fulcrum at d, and mounted in a bearing e fixed to the base of the lamp.
This lever embraces the wind-guard as far as its centre, and is pivoted to two
connecting rods, arms, or lovers f, f, which in their turn are pivoted to the wind-
guard on each side thereof by means of two studs f*,*. The lever D is provided
at its inner extremity with a thumb plate or knob d*, and its outer ends or forked
arms are cach provided with a nose or projection g to prevent the descent of the
wind-guard after it has been raised to its full height, which it would otherwise do
if the connecting rods f.f, were to pass the dead centres. The dotted lines in
Fig. 5 shew the wind guard in its raised position, which is effected by pressing the
thumb on the plate or knob d*; on releasing the thumb the wind-guard returns
to its normal position by reason of its own gravity.
Having now described the nature of the said Invention and in what manner the
same may be performed, I declare that I claim,—
The improved wind-guard or draft protector arranged upon an oil lamp, and
operating in the manner described, and substantially as shewn in the annexed
Drawings.
In witness whereof I, the said Christian Reimers, have hereunto set my hand
and seal, this Sixth day of October, in the year One thousand eight hundred
