PROVISIONAL SPECIFICATION left by the said Henry Harris Lake at the

HENRY HARRIS LAKE, of the firm of Haseltine, Lake and Co, Patent Agents,
Southampton Buildings, London "IMPROVEMENTS IN AND RELATING TO ROTARY
DEVICES FOR DISPLAYING ADVERTISEMENTS OR FOR SIMILAR PURPOSES "[A
communication to him from abroad by George Leander Chapin of Chicago,
Illinois, United States of America]
The present invention relates to rotary devices, such as globes, signs and shades
for display purposes.
The said invention comprises a drive wheel which has buckets bent down on
such curves as to form a continuous curve with a concave-conical or conical
deflector placed on the wheel-support, whereby the heat from the flame is directed
properly to the buckets to attain the greater power.
The said invention also comprises a gas-globe or lamp-globe suspended from a
rotating wheel which is, driven by the gas or lamp-flame and supported by a
standard passing through the globe and fastened to a gas or lamp burner.
The said invention further comprises a plumbago pivot-bearing and stone step
for the wheel to turn upon, and means for holding and adjusting the plumbago
pivot and the stone step for the wheel to turn upon, all as hereinafter described.
In carrying the said invention into practice I provide a disc of thin spring brass
or other suitable metal which has formed inwardly from its periphery radial cuts;
the pieces of metal or buckets thus separated have each a hole punched through
them and are bent downward and twisted. A wire is then passed through the

page_text: holes to hold the buckets in position, the ends of the wire being rivetted together,
thus forming what I term a bucket-wheel.,
To the underside of the said disc is attached a concave cone-shaped plate which
serves the purpose of strengthening the disc and deflecting the rising gases onto
the buckets. The concave form is the more efficient in that it directs the heat
more in a horizontal direction and with less friction than a cone would; but the
latter may, if desired, be used to perform the function of deflecting the heat to
propel the drive-wheel.
A hole is formed in the centre of the disc and surrounding it and on the top
thereof is rivetted a flat ring, and placed over and secured to this ring by screws is
a plate to the underside of which is secured a step in which the wheel-supporting
pivot-point bears.
The construction of the top of the supporting standard to hold this point is as
follows, that is to say;-On the said top part is formed a taper screw which is
alotted vertically and has a vertical hole in it to receive the said point.
A taper threaded nut is placed on the screw and by its compressing force holds
the pivot in place. Any anti-friction material which will withstand the heat may
be employed for the support of the wheel; but, I have found that hard plumbago
for the point, and stone, such as onyx bearings serve the purpose well and that
plumbago or some material in which plumbago is incorporated is the only substitute
that will answer the purpose for the said point under the action of heat without
lubrication; and it is for the purpose of using fine black-lead or composition points
that the top of the standard is constructed so that, as a point becomes worn, it
may be removed by loosening the nut, and another may be inserted in its place.
The standard is provided at its lower end with a collar which is of a size to be
placed onto an ordinary gas-burner, and it is held in place by a screw-cap.
The globe is suspended from the wheel by means of a chain or ring put around
under its top flange and chains attached to it and to the wire of the wheel.
Should pendants be desired they may be suspended from the buckets.
It will be understood from the above description that the standard remains in a
fixed position and that the wheel being rotated by the rising gases rotates the
globe, and the effect is produced by the devices on the globe or other rotated
device; the velocity the globe is to have depends on the size of the flame from the
burner,
It is well to state that where the standard is attached to the burner of a lamp
the same result will be produced.
The pendants serve the purpose of copernors as well as dienlev

pivot and the stone step, all as hereinafter described.
In the accompanying drawing
Figure 1 is an elevation of mechanism constructed according to this invention
Figure 2 is a vertical sectional elevation of the top portion thereof.
Figure 3 is a top or plan view of the plate of which the wheel is formed, it
being in the condition in which it comes from the dies with the radial cuts made
preparatory to bending the buckets.
Figure 4 represents the curved standard which supports the wheel, and
Figure 5 is a perspective view of the wheel bearing...
A indicates a disc of thin spring-brass or other suitable metal which has formed
inwardly from its periphery radial cuts m m; the pieces of metal or. buckėta n
thus separated have holes o punched through then and are bent downwards and
twisted as shown in figures 1 and 2. A wire B is passed through the holes o to
hold the buckets in position, the ends of the wire being rivetted together to form
what I term a bucket-wheel.
'
To the underside of the disc A is attached a cone F the sides of which are
preferably slightly concave as shown. This cone serves the purpose of strengthening
the disc and deflecting the rising gases onto the buckets n. The concave form is
more efficient than the other form, in that it directs the heat more in a horizontal
direction and with less friction than a cone would; but the latter may, if desired,
be used to perform the function of deflecting the heat to propel the drive-wheel.
A hole C is formed in the centre of the disc A, and surrounding it and on the
top thereof is rivetted a flat ring, 2; and placed over and secured to this ring by
screws t, t is a plate u to the under side of which is secured the step XL in
which the wheel supporting pivot point H bears
The construction of the top of the supporting standard G to hold this point is
as follows, that is to say-On the said top-part is formed a tapering screw I,
which is slotted vertically at J and has a vertical hole in it to receive the said
point H. A taper threaded nut K, is placed on the screw I, and by its compressing
force holds the pivot H in place
Any anti-friction material which will withstand the heat may be employed for
the support of the wheel; but I have found that hard plumbago for the point H,
and stone such as onyx bearings X, L, serve the purpose well, and that plumbago

page_text: or some material in which plumbago is incorporated, is the only substitute which
will answer the purpose for the said point H under the action of heat without
lubrication; It is for the purpose of using fine black-lead or composition points
that the top of the standard G is constructed so that as a point becomes worn it
may be removed by loosening the nut K, and another inserted in its place.
The standard G is provided at its lower end with a collar P, which is adapted
to be placed onto an ordinary gas-burner M and to be held in place by a
screw-cap 3.
The globe E is suspended from the wheel by means of a chain or ring D¹ put
around under its top flange, and chains D, D,
Should pendants S be desired they may be suspended from the buckets n.
It will be understood from the above description that the standard G remains in
a fixed position, the wheel A, n, F being rotated by the rising gases and rotating
the globe E; that the effect is produced by the devices on the globe or other
rotated device; and that the velocity the globe is to have depends on the size of
the flame at the burner M.
-
If the standard is attached to the burner of a lamp the same result will be
produced as herein before described.
The pendants S, serve tho purpose of governors as well as for ornament.
Having thus fully described the said invention as communicated to me by my
foreign Correspondent, and the manner of performing the same, I wish it
understood that I claim -
First. The wheel A having downwardly turned buckets n, in combination with
an inverted cone F formed on a continuous curve with the said buckets, as, and
for the purpose, specified
.
Second. A gas-globe or other similar device suspended from the rotating wheel A
n F, which is supported by the standard G passing through the globe and fastened
to a gas or lamp burner, as, and for the purpose, specified.
Third. The lumbago pivot H in combination with the stone X, as a bearing
for rotating bodies which are driven by heat for displaying advertisements or the
like, as specified.
