NOW KNOW YE, that I, the said John Hatchett, in compliance with the
proviso in the said Letter Patent contained, do hereby describe and ascertain
the nature of my said Invention mentioned in the said Letter Patent, and
berein-before mentioned, with the manner of my compleating my said Inven-
tion, that is to say :-
All the pannels made to put in and to take out when required; separate
frames fixed on the panels and rabetted into the framework of the body,
and fixed on with screws fitted and screwed into plate nutts, to take out and
screw in when required; the lining made to fix on straining frames laced on
to the backs of frames or stiched on the poof, laced on, to take off and put on
at pleasure; the pannels for those bodies and all other bodies of carriages, both
the upper and lower pannels, to be made of mahogany, rattan, or any other
sort of wood proper for the use, prepared with oil and varnish colours mixed
with white lead, yellow or stone oaker, or any other strong bodied colour, laid
all over on both sides the pannels, with a canvass, linen, tin-foil, flox, tow,
paper, or any other sort of materials as will hold the grain of the wood
together, to be well pressed or rubbed on; then to be thoroughly dried, after-
ward to be filled up with oil and varnish colour or or japan, &c., and mixed with
white lead, yallow or stone oaker, or any other strong bodied colour, till the
threads of the canvass are entirely covered; then put into a stove-room__and
thoroughly dried, or, in summer time, by the sun and air; then ground down
till it bears a smooth and even surface.-N.B. The above preparation is also
intended for boots of carriages, trunks, imperials, pannels for rooms, chimney
pieces, furniture, and pictures, or any articles made in wood intended to be
painted, ornamented, or highly varnished, which is to prevent the wood crack-
ing or splitting. Instead of iron loops fixed to the body as usual at

page_text: bottom, to have wood or iron polls or springs fixed through the back
between the lining and pannels and across each side to the standing pillar,
under or above each elbow, with loops or shackels, or round the pole only, to
receive braces or chains, which hang perpendicular, or near upon it, from the
springs of the carriage, which are fixed and lay horozontle across the carriage,
the same way as the axle trees lays, supported on standards nearly or directly
over the center of the fore and hind axletrees, to take the weight from the
perch or crane necks, and to give the body an easy and horozontle swing,
instead of rocking, and also to admit of the coach box and footman, stage
trunk, imperials, or all other articles, to ride on the same spring the body
hangs on; or from the poles may also be fixed to the bottom, if required, and
rise from that to any heigth to be even or above the roof, if required or neces-
sary, a swival or joint to the perch to let the carriage twist; the springs
of the carriage may also form to be fixed in manner as the Sketch or Draw-
ings under this Specification, if required. The wheels: the felleys, reduced in
length, or kept to the usual length, if required; instead of the joints coming
between the spokes, the felleys to meet and join over on the center of each
spoke; each joint to be crossed with edge plates behind and before, and revitted
together.
In witness whereof, I have hereunto set my hand and seal, the Seventeenth
day of February, in the year of our Lord One thousand seven hundred
