Year: 1879

page_text: LETTERS PATENT to Richard Russell Gubbins, Civil Engineer, of No. 17,
Park Road, New Cross, S.E., for the Invention of "AN IMPROVED PORTABLE
WHEEL"
Sealed the 23rd April 1880, and dated the 1st November 1879.
PROVISIONAL SPECIFICATION left by the said Richard Russell Gubbins at
the Office of the Commissioners of Patents on the 1st November 1879.
RICHARD RUSSELL GUBBINS, Civil Engineer, of No. 17, Park Road, New
Cross, S.E. "AN IMPROVED PORTABLE WHEEL."
My improved wheel may be used for any of the known mechanical purposes
where portability is required, but preferably for cases where it is inconvenient to
remove shafting or hangers for the purpose of replacing old wheels or adding new
ones.
With the above object I make a smaller portion than half of the periphery of
the wheel removable, together with one or more of the spokes or arms and a portion
of the boss, sufficient to admit the shaft; the removable part may be then replaced
& secured in its original position in the wheel.

RICHARD RUSSELL GUBBINS, Civil Engineer, of, 17, Park Road, New Cross, S.E.
AN IMPROVED PORTABLE WHEEL."
My improved wheel may be used for any of the known mechanical purposes
where portability is required, but preferably for cases where it is inconvenient to
remove shafting or hangers for the purpose of replacing old wheels or adding new
ones.
With the above object I make a smaller portion than half of the periphery of the
wheel removeable, together with one or more of the spokes or arms and a portion
of the boss sufficient to admit the shaft; the removeable part may then be replaced
in its original position in the wheel.
But to make my Invention better understood I will proceed to describe the same
by reference to the accompanying Drawing, in which Figure 1 is a perspective
view of a wheel constructed according to my improvements, and Figure 2 a similar
view shewing the smaller portion of the wheel being placed in its original position
on the wheel.
A is the wheel; B is the portion of the periphery thereof (less than one half)
which is removeable, together with one of the arms or spokes C, and a portion D
of the boss sufficient to admit the shaft; the two parts of the wheel may be secured
together in any suitable manner, as, for example, the parts of the boss may be
tongued and slotted, as shewn in the Drawing, and pins or bolts b, b, passed through
the holes a, a, and the parts of the periphery may be fixed together in the manner
shewn in the Drawing.
From this construction it will be seen that the wheel can be quickly and easily
placed on or removed from a shaft or hanger without it being necessary to take
down the shafting.
:
I am aware that it has been before proposed to employ split or divided pulleys
or wheels made in halves, and also split pulleys in which the boss was in halves,
but I lay no claim to either of these constructions, nor do I confine myself to the
form of wheel shewn in the Drawing, as the same may be varied without
departing from the peculiar character of my Invention; but what I claim is,-
A portable wheel having a smaller portion, than half the periphery thereof
removeable, together with one or more of the spokes or arms, and a portion of the
boss sufficient to admit the shaft, substantially as and for the purpose hereinbefore
described and represented in the accompanying Drawing.
In witness whereof, I, the said Richard Russell Gubbins, have hereto set my
hand and seal, this First day of May, in the year of our Lord One thousand
eight hundred and eighty.
Witness,
G. F. REDFERN,
