PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Dollying, Churning, and like
Operations.
We, WILLIAM PURDY, of Eastwood, in the County of Nottingham, Oculist,
and FREDERICK HENRY and SAMUEL HENRY trading together under the style or
Firm of Fred Henry and Son of 9 Derby Road in the Town and County of the
Town of Nottingham, House Furnishers do hereby declare the nature of this
invention to be as follows:-
:-
This invention relates to improvements in apparatus for dollying, churning, and
like operations, whereby labour and time are saved, and the dolly or plunger of the
apparatus is lifted for a fresh stroke, by mechanical means.
For the purpose of our invention the dolly or plunger is provided with one or
more helical or other shaped metal springs attached at one end to the dolly or
plunger, and at the other end to a suitable frame-work secured to, or suspended
over, the tub, washer, or churn. The attachment at either or both ends of the
spring, or springs, may be by means of a chain, link, hook, or other suitable device,
so as to enable the position of the said dolly or plunger to be adjusted.
By the arrangement of a spring or springs, as above mentioned; for lifting the
dolly or plunger, after it has been forced down by hand, the said dolly or plunger
can be made heavier than one which is moved entirely by hand, as there is a period
of rest for the hand, while the spring mechanism is doing its work, and thus the
operation of cleaning or washing all descriptions of clothes and fabrics, or that of
churning, is facilitated.
An indiarubber spring, or counterbalance, may be substituted for the metal spring,
in the case of light dollys. or plungers.
Improvements in Apparatus for Dollying, Churning, and like
Operations.
We, WILLIAM PURDY, of Eastwood, in the County of Nottingham, Oculist,
and FREDERICK HENRY and SAMUEL HENRY, trading together under the style
or Firm of Fred Henry and Son, of 9, Derby Road, in the Town and County of
the Town of Nottingham, House Furnishers, 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, reference being had
to the accompanying drawings and to the letters and figures marked thereon,
that is to say :-
This invention relates to improvements in apparatus for dollying, churning, and

page_text: like operations, whereby labour and time are saved, and the dolly or plunger of the
apparatus is lifted, for each fresh stroke, by mechanical means,
For the purpose of our invention, the dolly or plunger is provided with one or
more helical or other shaped springs, preferably of metal, attached at one end to
the dolly or plunger and at the other end to a suitable framework secured to, or
suspended over, the tub washer or churn. The attachment at either or both ends
of the spring, or springs, may be by means of a chain, link, hook, or other suitable
device, so as to enable the position of the said dolly or plunger to be adjusted.
By the arrangement of a spring or springs as above mentioned for lifting the
dolly or plunger after it has been forced down by hand, the said dolly or plunger
can be made heavier than one which is moved entirely by hand, as there is a period
of rest for the hand while the spring mechanism is doing its work, and thus the
operation of cleaning or washing all descriptions of clothes, and that of churning, is
facilitated.
An india rubber spring, or counterbalance, may be substituted for the metal
spring, in the case of light dollys or plungers.
This invention will be better understood by reference to the annexed drawings,
in which:
Fig. 1 is a sectional elevation of a dollying apparatus constructed according to
our invention, and Fig. 2 is a plan of the same.
Fig. 3 represents a modification in which a counterbalance is employed.
Fig. 4 shows the application of the invention to a churn.
Figs. 5 and 6 are sectional plan and elevation respectively, showing a means for
attaching the support for the spring to the tub or washer.
The frame or support a is preferably constructed of galvanised T bar, bent to
the desired form and attached to the tub or barrel b, by brass or galvanised iron
clips c, which are secured to the tub or barrel by galvanised iron bolts d, and nuts e,
or otherwise.
By unscrewing the nuts e, and removing the clips c, the frame or support a may
be removed from the tub or churn, when desired. The top end of the support a is
provided with three or more holes f so that the link or hook g, which carries the
helical spring h, may be adjusted to get the dolly or plunger in the required
position.
The dolly is connected with the helical spring by means of a wire loop i,
and a leather strap k, or its equivalent, in such a manner that the height of the
dolly in the tub may be adjusted as desired before commencing the dollying
operation.
Instead of the helical spring h, we may employ a lever m pivotted on the frame or
support a, and provided with a balance weight 1. This lever is connected to the
dolly or plunger i by means of a link or loop n, of india rubber, metal, or leather,
and the height or position of the dolly or plunger may be regulated by shifting the
balance weight along the lever m.
Or instead of the helical spring ha C or other shaped metal spring h' (see Fig. 4)
may be attached to the support or frame a, and be connected to the handle of the
plunger by a chain p, or other suitable means.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. In apparatus for dollying, churning, and like operations, the employment of a
spring, or its equivalent, for the purpose of lifting the dolly or plunger for a fresh
stroke, substantially as set forth."
2. The arrangement and combination of parts constituting the improvements in
dollying apparatus, substantially as herein before described and shown with reference
to Figs. 1 and 2 of the annexed drawings.
3. The arrangement and combination of parts constituting the improvements in

page_text: churning apparatus, substantially as hereinbefore described and shown with reference
to Fig. 4 of the annexed drawings.
4. Our improvements in apparatus for dollying, churning, and like operations,
herein before described and substantially as illustrated by the annexed drawings.
