Improvements in the Manufacture of "Peggy Dollies" for Laundry
Purposes.
I WILLIAM SMITH of Cleveland House, Wrekin Road Wellington, in the county
of Salop Manufacturer, do hereby declare the nature of this invention to be as
follows:-
"
This invention relates to the manufacture of what are known among domestics, for
laundry purposes, as peggy dollies and its object is to provide a new combination of a
dovetail form of mortise and tenon, with the securing of the pegs or feet of the dolly
to its base or disc, and after the manner hereinafter described.
Hitherto the practice has been to secure these parts by means of the upper end
of the pegs being a straight taper, or parallel, taking into a similar mortise hole
in the disc, and then secured either by pin or by wedge.
In this my invention however, I dispense with the pins and with the wedge, at
the same time produce a connection or joining of the two parts, which is simpler
and much more firm.
The general construction of the dolly, is that of the ordinary character and style,
consisting of a disc at its lower part, from which four, five, or more pegs or feet
project downwards, and slightly outwards, and further from the said disc upwards,
extends the pillar or tree, having at its upper part a cross bar or handle, by which
the implement is manipulated.
It is as before intimated, in connection with the securing of these feet or pegs
to their base or disc that this my invention is concerned.
I first bore the hole or mortise from each side of the disc, having a taler form,
and meeting in the centre, that is the central portion of the said hole, would he
smaller in diameter than the two outside, generally in an inch and half depth of
hole, the said holo would vary in diameter, about one eighth of an inch or there-
abouts, according to the nature of the wood employed. I then turn in a lathe, the
tenon upon the peg, having an external shape and size, corresponding to the hole
or mortise aforesaid, and further allow that the outer or entering end of the said
tenon, shall be a little longer than the hole, so as to project a little therefrom.
This extra length is also rounded or tapered off, so as to assist entrance into the
mortise. I now sharply drive the peg into the mortise, driving the outer enlarged
end of the tenon, through the contracted portion of the mortise, in which case the
wood of the disc yields at its contracted portion somewhat, and also the enlarged
portion of the tenon yields somewhat, to admit of the passage.
Having now passed it through, I apply a sharp blow to the protruding end of the
tenon after the manner of rivetting so to speak, which assists the re-yielding of the
somewhat compressed tenon, back to its normal size.
By reason of the sudden and momentary compression of the wood in order to
permit of the entrance of the tenon, I find that by a judicious allowance of variation
in the diameter of the mortise and tenon, such compression readily re-adjusts itself,
and the tenon quickly becomes a good fit. this being assisted as described, by the
rivetting blow given. The protruding end is then cut off, and the implement finished
as usual.

Improvements in the Manufacture of "Peggy Dollies" for Laundry
Purposes.
I WILLIAM SMITH, of Cleveland House, Wrekin Road, Wellington, in the county
of Salop, Manufacturer, 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 the manufacture of what are known among domestics, for
laundry purposes, as peggy dollies, and its object is to provide in combination there-
with the use of a peculiar dovetail form of mortise and tenon, for securing the pegs or
feet of the dolly to its base or disc, and after the manner bercin further described.
Hitherto the practice has been to secure these parts by means of the upper end of
the pegs being a straight taper or parallel, taking into a similar mortise bhole in the
disc, and then secured either by pin or by wedge.
In this my invention however, I dispense with the pins and with the wedge, at the
same time produce a connection or joining of the two parts which is simpler and much
more firm.
In order to more particularly explain and describe this my invention, and how it is
to be performed, I have appended hereunto an illustrative sheet of drawings upon
which are figures and letters of reference, similar letters referring throughout the
several views to the same thing or part, and in which :-
Fig. 1, is a sectional view of the double dovetail mortise.
Fig. 2, is a view in elevation of the tenon, ready for the mortise.
Fig. 3, is a view showing the tenon within the mortise ready for cleaning off &c.
Fig. 4, is a view in olevation of a peggy dolly, to which this my invention is
applied.
The general construction of the dolly is that of the ordinary character and style,
consisting of a disc a, at its lower part from which four, five, or more pegs or feet 6,
project downwards, and slightly outwards; and further from the said disc a, upwards,
extends the pillar or tree c, having at its upper part, a cross bar or handle d, by which
the implement is manipulated.
It is, as before intimated, in connection with the securing of the feet or pegs b, to
their base or disc a, that this my invention is concerned.
I first bore the hole or mortise e, Fig. 1, from each side of the disc, and having a
taper form, meeting in the centre, that is the central portion of the said hole would be
smaller in diameter than the two outsides, generally in an inch and half depth of hole,
the said hole would vary in diameter about from one, to three eights of an inch or
thereabouts.
The tenon is now made having an external shape and size adapted to the hole or
mortise e, aforesaid, and further allow that the outer or entering end g, of the said
tenon shall be a little longer than the hole, so as to project a little therefrom.
This extra length is also rounded or tapered off so as to assist. entrance into the
mortise.
I now sharply drive the end 9, into the mortise e, driving the outer enlarged end of
the tenon through the contracted portion of the mortise, in which case the wood of
the disc yields at its contracted portion somewhat, and also the enlarged portion of the
tenon yields somewhat, to admit of the passage. Having now passed it through, I
apply a sharp blow upon the protruding end of the tenon after the manner of rivetting
so to speak, which assists the re-yielding of the somewhat compressed tenon back
to its normal size.
By reason of the sudden and momentary compression of the wood in order to permit
of the entrance of the tenon, I find that by a judicious allowance of variation in the
diameter of the mortise and tenon, such compression, readily re-adjusts itself, and the
tenon quickly becomes a good fit, this being assisted as described by the rivetting
blow given.

page_text: To produce the best results I find it an advantage to use all the wood quite dry, and
for a short time previous to the insertion of the tenon, to submerge the said tenon
(only) in hot water.
The protruding end is then cut off, and the implement finished as usual.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The improved method of manufacturing peggy dollies by the combination there-
with of the double dovetail mortise and tenon, and the manner of its application,
substantially as described and illustrated upon the drawings, and for the purposes
specified.
