page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
BENJAMIN GEITHNER, of Birmingham, in the County of Warwick, Brass
founder, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirteenth day of October, in the seventh year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Frederick Benjamin Geithner, His especial. licence, full power, sole privilege
and authority, that I, the said Frederick Benjamin Geithner, my exors,
adiors, and assigns, or such others as I, the said Frederick Benjamin
Geithner, my exors, admors, or assigns, should at any time agree with, and
no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, my Invention
of "IMPROVEMENTS APPLICABLE TO THE DRAWING OR WINDING UP OF WINDOW AND
OTHER ROLLER BLINDS OR MAPS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO
OTHER USEFUL PURPOSES;" in which said Letters Patent is contained a proviso
that I, the said Frederick Benjamin Geithner, shall cause à particular de-
scription of the nature of my said Invention, and in what manner the same is
to be performed, to be inrolled in His said Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said in
part recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Frederick Benjamin Geithner, do hereby declare the nature of my said Inven-
tion, and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, reference being had
to the Drawing hereunto annexed, and to the figures and letters marked
thereon (that is to say) :-
My Invention consists in the application and arrangement of certain
mechanical parts for obtaining an improved movement for drawing or winding-
up and letting down of window blinds, maps fixed on rollers, part of which
improvements I also apply to certain description of looking glasses called
dressing or swing glasses.
And in order that my Invention may be fully understood and the manner
in which the same is to be effected or performed, I will describe the
|--Figure_1_represents_a_roller blind complete, having my improvements
applied thereto; Figure 2 shews a perfectly smooth globular ball, which I
make of iron or any other metal or composition, and which I firmly rivet or
otherwise fasten to the collar, as represented; Figure 3 shews a clip, with
corresponding concave beds to receive the said ball, and which clips I make of
brass or any other suitable metal, and I sometimes inlay or line the bed or
concavity of the said clip with leather or other suitable material, to obtain
a smooth and easy movement; Figure 4 shews a thumbscrew, which
acting either as a contracting or expanding power upon the clip serves on
the one hand to cause a sufficient friction to keep the blind in any given
position (and which by means of the screw may easily be increased) or, on
the other hand, by a contrary revolution of the screw the friction is diminished
or the ball may be entirely released, and the blind removed at pleasure. I
sometimes reverse the parts of my said Invention, attaching the clip to the
collar or roller, placing the ball on the opposite part of the furniture, see
Figure 5. I do not confine myself to the screw only for regulating the clip.
I sometimes apply a spring weight, or any other mechanical power, to effect
this object. Figure 6 represents a roller with two sides to receive the line
necessary for wind up the blind; underneath this roller is fixed a clip guide,
Figure 7, which is slightly compressed by means of a small spring or any
other power, and which causes the line travelling through this guide to wind
itself tightly round the roller, preventing it getting entangled, and keeping it
in its proper situation on the rollers, when the blind is drawn down. Figure 8

page_text: represents a dressing glass, to which my ball movement is applied for the
purpose of swinging or turning the glass instead of the screws commonly used
for this purpose. Figure 9 shews a ball firmly fixed to a small plate, and
apparatus of this description is attached to each standard of the swing glass.
Figure 10 shews a metal box with a moveable bed or clip, one such is to be
fastened on each side of the frame of the swing glass to receive the ball,
which being acted upon by a small screw, Figure 11, passes on the clip
sufficiently to produce the desired friction, and which, after being regulated by
a few revolutions of the screw, does not require alteration, or sometimes I
use only one of the above apparatus, supplying the other side with any
convenient movement or pin.
I lay no claim to the Invention of any particular mechanical part of the
roller blind or maps already in use, nor to the parts of the swing looking
glasses, excepting the application of the ball movement and clip guide herein
described; these I sometimes use separately or together as best suits my
purpose.
But what I claim are the improvements above described.
First, the apparatus consisting of the ball movement with adjusting sockets
or bearings for window and other roller blinds, and for swing looking-
glasses as above described.
And, secondly, the clip guides for the drawing up cords of roller blinds and
maps, as above described.
In witness whereof, I, the said Frederick Benjamin Geithner, have
hereunto set my hand and seal, this Twenty-eighth day of March, in
the year of our Lord One thousand eight hundred and thirty-seven.
FREDERICK BENJAMIN (L.S.) GEITHNER.
AND BE IT REMEMBERED, that on the Twenty-seventh day of March,
in the year of our Lord 1837, the aforesaid Frederick Benjamin Geithner
came before our said Lord the King in His Chancery, and acknowledged
the Specification aforesaid, and all and every thing therein contained and
