We, ALFRED RÉNÉ UPWARD, and ROBERT DALMER, both of 19, Old Queen
Street, Westminster, Engineers, do hereby declare the nature of this invention
to be as follows:―
This invention relates to apparatus employed in mechanism for the display
of transformable inscriptions pictures and the like for the purpose of advertise-
ment such as that patented to us under No. 6736 of 1895, and consists of im-
provements in the structure and mode of manufacture of triangular rotating
spokes used in such advertisement display apparatus for presenting various
faces in succession to form successive various pictures or inscriptions.
The requirements for such a spoke is that it shall not be subject to warping or
shrinkage, by age or climatic effects as would be the case with wood, and that
it shall not show winding or distortion after manufacture; it must be light and
strong and the component parts forming the spoke must be of a simple and
well known form of production to render the manufacture easy and cheap.
We fulfil these requirements by forming the body of the device by a light
solid drawn tube of circular section preferably of steel and to this we fit two
equilateral triangular heads preferably of wood pinning the same to the ends of
the light cylindrical tube, so that the flat faces of the triangular heads are flush
with or tangential to the outside periphery of the circular tube.
The faces of the triangular heads may if necessary be faced one to the other
and to the periphery of the connecting tube upon an ordinary face plate so that
the whole is true and without winding.
I then cover or clothe the whole tube with three faces preferably of tinned
iron held in position upon the triangular heads and on the body of the circular
tube if desired, as the flat faces rest tangentially upon the periphery of the
internal body tube.
The edges of such tin faces where they abut may be easily closed by solder
or other equivalent means. It is obvious the three faces may be made from one
complete plate suitably bent into form.
The resulting spoke thus presents three perfectly flat and true sides of equila-
teral section throughout, and is very light and strong, and easy and cheap of
manufacture.

Inscriptions, Pictures, and the like, for the Purpose of Advertise-
ment.
We, ALFRED RÉNÉ UPWARD and ROBERT DALMER, both of 19, Old Queen
Street, Westminster, Engineers, 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 apparatus employed in mechanism for the display
of transformable inscriptions pictures and the like for the purpose of advertise-
ment such as that patented to us under No. 6736 of 1895, and consists of im-
provements in the structure and mode of manufacture of triangular rotating
spokes used in such advertisement display apparatus for presenting various
faces in succession to form successive various pictures or inscriptions.
The requirements for such a spoke is that it shall not be subject to warping or
shrinkage, by age or climatic effects as would be the case with wood, and that
it shall not show winding or distortion after manufacture, it must be light and
strong and the component parts forming the spoke must be of a simple and
well known form of production to render the manufacture easy and cheap.
We fulfil these requirements by forming the body of the device by a light
solid drawn equilateral tube of circular section preferably of steel; and to this
we fit two triangular heads preferably of wood, pinning the same to the ends of
the light cylindrical tube, so that the flat faces of the triangular heads are flush
with or tangential to the outside periphery of the circular tube.
The faces of the triangular heads may if necessary be faced one to the other
and to the periphery of the connecting tube upon an ordinary face plate so that
whole is true and without winding.
We then cover or clothe the whole tube with three faces preferably of tinned
iron held in position upon the triangular heads and on the body of the circular
tube if desired, as the flat faces rest tangentially upon the periphery of the
internal body tube.
The edges of such tin faces where they abut may be easily closed by solder
or other equivalent means.
It is obvious the three faces may be made from one complete plate suitably
bent into form.
The resulting spoke thus presents perfectly flat and true sides of equilateral
section throughout, and is very light, strong and easy and cheap of manufacture.
And in order that our invention may be the better understood we now proceed
to describe the same with reference to the drawings hereto annexed and to the
figures and letters marked thereon..
Figure 1 is a broken sectional elevation of our triangular spoke.
Figure 2 is a transverse section thereof.
A is a central light solid drawn tube preferably of steel and B.B are two
equilateral triangularly shaped heads, preferably of wood, fitting into the ends
of the central tube, and pinned therein by a pin C.
DDD are the surrounding sheets of light metal, such as tinned iron, which
are built up, on the triangular heads B, and rest also tangentially upon the
periphery of the central tube A.
The edges of such tin faces D) D D are joined by solder or other equivalent
means, or may be bent from a single sheet with only one joint closed by solder
or other means.

page_text: Where the spokes are short in length the central tube A may be omitted and
a third triangular block may be used at the centre to further support the flat
faces D D Ď.
As a finish to the construction of this spoke may stretch a cover of textile
fabric such as canvas, preferably fine, over the outer faces of the plates D D D,
and treat the said fabric with a hard drying varnish such as shellac.
For rotation of the spoke with the least frictional resistance I mount the same
upon centre points E Ebearing on metal or other hard blocks F F let into the
triangular ends.
The desired rotation of the spoke may be effected in any convenient manner,
as for instance by a crown wheel G and horizontal shaft H with a pin pinion K
thereon, as shown.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1st. In an advertisement display device, the construction of light hollow flat
faced spokes, consisting of in combination a central drawn tube end wooden
plugs or blocks conformable in shape to desired form of periphery, flat facing
surfaces built upon said plugs or blocks, soldered at joining edges and enveloped
by a shrunk canvas cover treated with a varnish, substantially as described.
2nd. The construction and arrangement of parts for a hollow flat faced spoke
for advertisement display purposes substantially as described and illustrated
herewith.
