of the Commissioners of Patents, with his Petition, on the 18th April
1859.
I, ALEXANDER DALRYMPLE, of Sheffield, in the County of York, Tailor, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MODE OF COVERING CRINOLINE, AND IN MACHINES USED IN CONNECTION THEREWITH,"
to be as follows:-
Hitherto crinoline has been covered by weaving upon it the covering
material, or sewing such material by hand upon it. I propose to weave the
covering material first, and apply it to the crinoline by any of the following
processes :-
1st. I use a machine consisting of a drum or reel, a pair of rolls, an over-
lapping guide or feeder, and boxes to contain the covering material, and an
adhesive composition, through which the crinoline passes. The revolution
of the drum is adjusted to receive the covered crinoline as it passes through
the rolls; the action of the rolls draws the crinoline through the box
containing adhesive composition, and draws at the same time the covering
material with it (from a frame nearer the rolls) into and through the over-
lapping guide which is formed with a triangular mouth or inlet to depress or
lap the covering upon the edges of the crinoline as it is being drawn through.
This guide is wedge-shaped longitudinally, the outlet being reduced so as
merely to admit the crinoline with the covering closely laid. upon it to pass
through. When pressed between the rolls, the edges of the covering become
firmly united by the adhesive composition.

page_text: 2nd. I use a drum or reel, a pair of rolls, and an overlapping guide as
before described. The guide is regulated so as accurately to double the
covering material in such manner upon the crinoline that the edges overlap
one edge. A sewing machine is placed close to the outlet of the guide, and
regulated to unite the edges of the covering as it is being drawn forward.
3rd. I unite the edges of the covering material apart from the crinoline by
the second process; I then use a machine consisting of a reel, on which
crinoline is wrapped, and a pair of draw rolls; in advance of the draw rolls I
introduce a frame with small hooks, to which the ends of the covers with the
edges united are fastened; in advance of this is a single travelling roll, and at
some further distance another roll, on which the covers are laid; both these
rolls are connected with and have the same motion communicated to them as
the draw rolls. When the machine is in action, the end of the crinoline
(rounded) is introduced into the covers, and forced continuously into them,
the ends of the covers being secured to the fixed hooks.
4th. Instead of uniting the edges of the covering material by the second
process, I use a machine in other respects similar to that described for the
first process, but dispensing with the box through which the crinoline is passed,
and substituting for the box which contains the covering material, a large
roller or wheel in a box with adhesive composition at the bottom. This
roller is fluted or made concave the full width of the periphery in a direction
at right angles to its axis, and is so adjusted, that when revolving, the pro-
minent edges only of the periphery become immersed in and take up the
adhesive composition; the covering material is drawn over the top of this
roller, so that the edges come in contact with the adhesive composition; in
passing through the overlapping guide it is doubled, and in passing through
the rolls compressed, and the edges united. I then force the crinoline into
them by the 3rd process.
5th. In conjunction with a machine commonly known as the ", gimp
machine," I use an overlapping guide and rollers as herein-before described.
