PROVISIONAL SPECIFICATION.
Improvements in Revolving Stands for Books, Albums, Drawings,
Works of Art, and for Exhibiting Goods generally.
I, FREDERICK JAMES TIFFIN of 3 Great Winchester Street, in the City of
London, General Merchant do hereby declare the nature of this invention (a com-
munication from Oskar Edmund Wenström, of the Grammar School Wisby, Isle
of Gotland, Sweden Schoolmaster) to be as follows
1
One object of this apparatus is to bring within each reach and inspection and
without loss of time large books such as ledgers used in banks and other large estab-
lishments. The apparatus is also useful for exhibiting drawings, albums, works of
art and other objects in a limited space without their being handled, also for
exhibiting goods generally in shop windows and other places, and it may then be
driven slowly round by some mechanical power.
The apparatus is constructed on the principle of a paddle wheel with feathering
paddles each of which is formed as a table or desk for holding the book or other
article, which tables when the wheel is rotated are kept always horizontal or at the
same angle to the horizon. The tables (which may be fitted with desk ledges) are
each pivoted in wheel arms on a sleeve which can be rotated on an axle mounted
in a stand or frame. The outer ends of the pivots at one side of the wheel are bent
in the form of a crank, the end of which enters corresponding arms of another wheel
or system of arms. The boss of this wheel works on an eccentric or eccentric ring
fixed on the axle or on the frame. To prevent the apparatus from being set in:
motion when unequally loaded the rotating wheel can be locked in position by
screwing up a lever on the screwed end of the axle which causes the paddle wheel
boss to be pressed against the frame. Or I may use any other suitable stopping or
braking appliance. The eccentric may be shifted round by means of a lever con-
nected thereto and capable of being fixed by thumb nut on a pin which works in a
curved slot on the frame; the required angle of the paddles or tables can thus be.
obtained by loosening the nut and shifting the lever into another position. When
the paddles or tables are in a horizontal position the apparatus is suitable for
exhibiting terra-cotta figures and other objects requiring always to be in an upright
position. For exhibiting such and other goods the wheel may be provided with a
pulley or wheel to be driven by some motive power.

COMPLETE SPECIFICATION.
Improvements in Revolving Stands for Books, Albums, Drawings,
Works of Art, and for Exhibiting Goods generally.
I, FREDERICK JAMES TIFFIN of 3 Great Winchester Street in the City of
London General Merchant do hereby declare the nature of this invention (a com-
munication to me from abroad by Oskar Edmund Wenström of the Grammar School
Wisby Isle of Gotland, Sweden, Schoolmaster) and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement :-
One object of this apparatus is to bring within easy reach and inspection and
without loss of time large books such as ledgers used in banks and other large

page_text: establishments. This apparatus is also useful for exhibiting drawings, albums, works
of art, and other objects in a limited space without being handled, also for exhibiting
goods generally in shop windows and other places and it may then be driven slowly
round by some mechanical power.
The apparatus is constructed on the principle of a paddle wheel with feathering
paddles each of which is formed as a table or desk for holding the book or other
article, which tables when the wheel is rotated are always kept horizontal or at fhe
same angle, to the horizon means being provided for changing the angle.
In the accompanying drawings
Fig. 1 is an end view of a simple form of wheel stand constructed according to
this invention and
Fig. 2 is a part sectional front elevation of same.
The tables A which may be fitted with lower desk ledges as shown are each
pivoted in wheel arms B₁ on a sleeve B which can be rotated on an axle C mounted
in a stand or frame D. The outer ends of the pivots at one side of the wheel are
bent in the form of a crank E the ends of which enter corresponding arms F¹ of
another wheel or system of spokes. The boss F of this wheel works on an eccentric G
fixed on the axle C or on the frame D. To prevent the apparatus from being set
in motion when unequally loaded the rotating wheel B B can be locked in position
by screwing up a lever H on the screwed end of the axle C which causes the paddle
wheel boss B to be pressed against the frame D. Or I may for the same purpose
use any other suitable stopping or braking appliance. The eccentric G can be
shifted round in its bearings in the stand D by means of a lever I fixed on its
central boss and capable of being fixed by thumb nut I' on a pin 12 which works in
a curved slot K on the frame D; the required angle of the tables A can thus be
obtained by loosening the nut I¹ and shifting the lever I into another position.
When the tables A are in a horizontal position the apparatus is suitable for
exhibiting terra cotta figures and other objects requiring to be always in an upright
position. For exhibiting such and other goods the wheel may be provided with a
pulley or wheel to be driven by some motive power.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A revolving stand with wheel having desks or tables on the principle of the
feathering paddle wheel and provided with means for changing the angle of the
desks and for retaining same at the desired angle, substantially as set forth.
2. The construction of revolving wheel stand shewn on the drawing.
