Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord
Street, Liverpool, and 6, Bank Street, Manchester, both in the County of
Lancaster, and Lower Temple Street, Birmingham, in the County of Warwick,
Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
=
My invention relates to spinning tops, and its object is to provide an improved
construction of the same by which the rotary or spinning movement is caused
or effected by an air blast."
The invention consists essentially in a sectional or two part shell, one of
which sections is provided with a number of curved inwardly projecting tongues
or buckets, a tube on which said sections are journaled, extending into said
shell and provided with radial curved pipes and provided with a shaft extending
through the lower section, as hereinafter described.
In the accompanying drawing,
Figure 1 is a side elevation of a spinning top constructed in accordance with
my invention.
Figure 2 is a longitudinal section of the same.
Figure 3 is a horizontal section.
In the said drawing, the reference numerals 1 and 2 designate the two
sections comprising the shell of the top formed at their adjoining ends with
upwardly and downwardly extending cylindrical flanges 3 and 4 which telescope
with each other.
Passing loosely through the upper section 1 is an air tube 5. provided with a
collar or washer 6. This tube extends into the shell and at its lower end is
provided with a plug 7 to which is secured a pin or shaft 8 extending through
the lower section and forming the spinning point of the top.
A collar or
washer 9 is secured to said pin or shaft and in conjunction with the collar or
washer 6, holds the two sections 1 and 2 together.
At the lower end of said tube and communicating therewith are radial
pipes 10, the outer ends of which are curved backwardly, as seen more clearly
in Figure 3.
The lower section 2 of the top is formed with a number of inwardly project-
ing tongues or buckets 13 formed by slitting the material of said section "and
then bending it inwardly so that the said tongues are formed integral with
said section. A space or opening 14 is thus, formed in said section with which
coincide openings 15 in the upper section for the escape of the air blown into
the top. In practice, air is blown into the tube 5 which escaping from the

page_text: radial pipes 10 will impinge upon the tongues 13 and thus revolve the shell.
If the top be now placed upon an object with the lower end of the shaft 8 in
contact therewith, a rapid rotary or spinning motion will be given to the top.
It will of course be understood that while the tube 5 is held by the operator
who blows thereinto, the shell will rotate while the tube remains stationary,
but when the shaft 8 is placed on a surface both the shaft and the shell will
rotate together. The openings in the overlapping or telescoping portions of
said sections allow the air which has been blown into the tube to escape.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord
Street, Liverpool, and 6, Bank Street, Manchester, both in the County of
Lancaster, and Lower Temple Street, Birmingham, in the County of Warwick,
Civil Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
This invention relates to spinning tops, and its object is to provide an improved
construction of the same by which the rotary or spinning movement is caused
or effected by an air blast.
The invention consists essentially in a sectional or two part shell, one of
which sections is provided with a number of curved inwardly projecting tongues
or buckets, a tube on which said sections are journaled, extending into said
shell and provided with radial curved pipes and provided with a shaft extending
through the lower section, as hereinafter described.
The invention is illustrated in the drawing accompanying the Provisional
Specification, in which:
Figure 1 is a side elevation of a spinning top constructed in accordance with
my invention.
Figure 2 is a longitudinal section of the same.
Figure 3 is a horizontal section.
In the said drawing, the reference numerals 1 and 2 -designate the two
sections comprising the shell of the top formed at their adjoining ends with
upwardly and downwardly extending cylindrical flanges 3 and 4 which telescope
with each other.
Passing loosely through the upper section 1 is an air tube 5 provided with a
collar or washer 6. This tube extends into the shell and at its lower end is
provided with a plug 7 to which is secured a pin or shaft 8 extending through
the lower section and forming the spinning point of the top. A collar or
washer 9 is secured to said pin or shaft and in conjunction with the collar or
washer 6, holds the two sections 1 and 2 together.
At the lower end of said tube and communicating therewith are radial
pipes 10, the outer ends of which are curved backwardly, as seen more clearly
in Figure 3.
!
The lower section 2 of the top is formed with a number of inwardly project-
ing tongues or buckets 13 formed by slitting the material of said section and
then bending it inwardly so that the said tongues are formed integral with

page_text: said section. A space or opening 14 is thus formed in said section with which
coincide openings 15 in the upper section for the escape of the air blown into
the top. In practice, air is blown into the tube 5 which escaping from the
radial pipes 10 will impinge upon the tongues 13 and thus revolve the shell.
If the top be now placed upon an object with the lower end of the shaft 8 in
contact therewith, a rapid rotary or spinning motion will be given to the top.
It will of course be understood that while the tube 5 is held by the operator
who blows thereinto, the shell will rotate while the tube remains stationary,
but when the shaft 8 is placed on a surface both the shaft and the shell will
rotate together. The openings in the overlapping or telescoping portions of
said sections allow the air which has been blown into the tube to escape.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, as communicated
to me by my foregn correspondent, I declare that what I claim is:-
1. In a spinning top, the combination with the shell provided with inwardly
extending tongues, of the air tube having radial pipes communicating there-
with and a shaft extending through the lower end of the shell, substantially
as described.
2. In a spinning top, the combination with the sectional shell provided with
cylindrical telescoping flanges at the adjoining ends, of the air tube extending
down into said shell and provided with a shaft projecting through the lower
end of said shell, and said tube provided with radial curved tubes, and one
of said sections provided with integral inwardly extending tongues, substantially
as described.
3. In a spinning top, the combination with the shell comprising the two
sections formed with cylindrical telescoping flanges and the inner flange formed
with a number of inwardly extending curved tongues or buckets integral there-
with and with openings in the rear thereof, and the outer flange provided with
coinciding openings, of the tube extending down into said shell, the plug at
the lower end thereof, and the shaft secured to said plug and extending through
the lower section of the shell, substantially as described.
4. The improved spinning top constructed and operating substantially as
described.
