PROVISIONAL SPECIFICATION.
Improvements in Counterweights for Electric Light Pendants, and
other similar purposes.
We JOHN GRUBB, of The Upland, Alvechurch, in the County of Worcester,
Manufacturer, and WILSON HENRY STURGE, of 17 Frederick Road, Edgbaston,
in the City of Birmingham, Electrical Engineer, do hereby declare the nature of.
this invention to be as follows :-
This invention relates to improvements in the construction and arrangement of
counterweights, more particularly intended for electric light pendants, but which
may also be used for other similar purposes; and has reference specially to the
means provided for the charging or loading of the said weight.
We construct this our improved weight as follows:-The main body or shell of
the article is stamped, cast or otherwise built up after the ordinary manner, except
so far as its upper end is concerned. This said upper end is usually reduced in
diameter so as to form a neck-like part with a vase above it. This vase is made
separate from the body, the bottom of the vase being made with a flat surface, and
the upper end of the body of a similar surface, each having a central hole through
which a screw pin passes whereby the two may be drawn together. In each of
these flat surfaces and around the central pin hole, one or more holes or slots are
made through which the shot or other charging material may be passed. Usually
the central screw pin serves to bind the cord pulley fork, vase, and body together,
but sufficiently tight only to permit of the vase being turned around when required,
so as to bring the hole or holes in the vase bottom, fair with the hole or holes in
the upper surface of the body, to allow of the shot passing into the latter.
The function of the vase, independently of the ornamental character it imparts
to the fitting, is by reason of its funnel like shape to act as a reservoir for the shot
whilst it is pouring through the holes into the body.
When charged the vase may be turned round so that such holes in the body may
be covered, and thus prevent any possible loss of the shot.
Thus a convenient and expeditious arrangement for charging is provided, in
combination with the vase and body which at the same time is neat in appearance,
and safe in use.
Dated this 16th day of March 1894.

COMPLETE SPECIFICATION.
Improvements in Counterweights for Electric Light Pendants, and
other similar purposes.
We JOHN GRUBB, of The Upland, Alvechurch, in the County of Worcester,
Manufacturer, and WILSON HENRY STURGE, of 17 Frederick Road, Edgbaston,
in the City of Birmingham, Electrical Engineer, 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 improvements in the construction and arrangement of

page_text: counterweights, more particularly intended for electric light pendants, but which
may also be used for other similar purposes; and has reference specially to the
means provided for the charging or loading of the said weights.
In order to more particularly explain this our invention, we have appended
hereunto an illustrative drawing upon which are figures and numbers of reference
similar numbers referring throughout the several views to the same thing or part.
Fig. 1, is a general view in elevation of a counterweight constructed according
to our invention.
Fig. 2, is a view in sectional elevation of the counterweight.
Fig. 3, is a plan view with the cord pulley &c. removed, and showing the charging
holes open.
Fig. 4, is a plan view with the cord pulley &c. removed, and showing the charging
holes closed.
Fig. 5, is an inverted view in detail of the bottom of the vase, and Fig. 6, a plan
view in detail of the top of the body or shell.
We construct this our improved weight as follows:-The main body or shell 7,
of the article is stamped, cast or otherwise built up after the ordinary manner,
except so far as its upper end or vase 8 is concerned. This vase is usually reduced
in diameter so as to form a neck-like part 9. This vase is made separate from the
body, the bottom 10, of the vase being made with a flat surface, and the upper
end 11 of the body 7, of a similar surface, each having a central hole 12, 12ª,
through which a screw pin 13, passes whereby the two may be drawn together by
the nut 14, or similar means. In each of these flat surfaces 10 and 11, and around
the central pin hole, one or more holes or slots 15, 15*, are made through which the
shot or other charging material may be passed. Usually the central screw pin 13,
serves to bind the cord pulley fork, vase, and body together, but sufficiently tight
only to permit of the vase 8, being turned around when required, so as to bring the
hole or holes 15, in the vase bottom fair with the hole or holes 15°, in the upper
surface of the body, to allow of the shot passing into the latter.
The function of the vase, independently of the ornamental character it imparts
to the fitting, is by reason of its funnel-like shape to act as a reservoir for the shot
whilst it is pouring through the holes into the body.
When charged the vase 8, may be turned round as seen in Fig. 4, so that such
holes 15ª, in the body may be covered, and thus prevent any possible loss of the
shot.
Thus a convenient and expeditious arrangement for charging is provided, in
combination with the vase and body which at the same time is neat in appearance,
and safe in use.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
The combination in a counterweight such as is herein described, of the vase 8,
having the openings 15, with the body 7, having the openings 15", the whole being
constructed and operating substantially as shown and described.
