PROVISIONAL SPECIFICATION.
Improvements in Ironing Machines.
I, WILLIAM HOOK DAVEY, of 25 Holmesdale Road, Highgate, in the County of
Middlesex, Engineer do hereby declare the nature of this invention to be as
follows:
My invention relates to improvements in ironing machines of that description in
which the iron or irons reciprocate longitudinally upon a revolving cylinder which
constitutes the ironing table.
According to my present improvements three steam-heated irons, whose faces are
curved to the circle of the cylinder on which they rest, are arranged side by side and
extend the full length of the cylinder the middle one only having a longitudinal
reciprocating motion between the outer ones which are stationary. The outer irons
are, however, capable of vertical motion together with the middle one, for introducing
and arranging the fabric to be ironed if necessary, the outer irons being vertically
guided in the frame, whilst the middle iron has cross-heads that reciprocate in guides
on the backs of the outermost irons, so that all grease is kept well away from the
ironing faces.
By this mode of mounting the irons all tendency of the irons to fall away from the
cylinder is avoided. The irons are raised and lowered simultaneously by a treadle
operating eccentric or crank motions with which the side irons are connected. The
cylinder would be driven through a clutch or other suitable mechanism, by means
of which it may be rendered stationary for a time without stopping the movement
of the reciprocating iron. This would be required at times, as, for instance, for
imparting a high finish to an article.

COMPLETE SPECIFICATION.
Improvements in Ironing Machines.
I, WILLIAM HOOK DAVEY, of 25, Holmesdale Road, Highgate, in the County of
Middlesex, 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:-
My invention relates to ironing machines of that description in which the irons
rest upon a revolving cylinder upon which the goods are placed and by which they
are carried beneath the irons. The improved machine is provided with two stationary
and one longitudinal reciprocating iron situated between the other two but so
connected thereto that all three may be raised together off the cylinder for introducing
and arranging the goods to be ironed.
Reference is to be had to the accompanying drawings, forming part of this
Specification wherein
•
Figure 1 is a part sectional front elevation, Figure 2 an end elevation, and Figure 3
a part séctional plan, of the ironing machine.
Figure 4 shews the iron-elevating mechanism separately.
Similar letters of reference indicate like parts in all the figures.
A is the revolving blanket-covered cylinder carried by a shaft mounted in bearings
in the framing and driven by worm gear from the first motion shaft B. CCC are

page_text: the three steam-heated irons whose ironing faces are curved to fit the circumference
of the cylinder over the whole length of which the irons extend side by side. The
two outermost irons C C are held stationary by end studs c received in vertical
guides c¹ on the pillars of the frame which permit of the irons being raised off the
cylinder. The middle iron C receives longitudinal reciprocating motion from an
eccentric D on a shaft E, the eccentric rod being coupled to the back of the iron at
about the middle of its length. The iron C is provided with cross-heads f which
extend across the back of the iron and are received at the ends in horizontal guides
in brackets F fixed upon the irons (whereby the iron is both guided in its
reciprocating motion and caused to rise along with the irons (when the latter are
lifted off the cylinder, the cross-head guides being so situated that no grease will be
likely to soil the goods. The eccentric shaft E is made in two parts coupled
together by a clutch G and driven by spur-gear from the first motion shaft B.
By means of this clutch the iron may be thrown out of gear and remain stationary
while the cylinder revolves on first introducing the fabric.
The mechanism for raising the irons off the cylinder is operated by either of two
treadles H situated one near each end of the machine and each coupled by a pair
of links I with crank arms i on a pair of rock shafts K whose journals kare
eccentric to the shafts and are mounted in bearings in the frame, the rock shafts K
being connected by links L with studs on the ends of the irons C so that by
depressing either treadle both rock shafts will be partially rotated and the whole
set of three irons raised together off the cylinder. It will be evident that, instead
of the rock shafts turning eccentrically, lover or crank arms, or other mechanical
equivalent, may be used for raising the irons.
The several irons are hollow, and have the usual pipe connections for the supply
and exhaust of steam. By the use of a stationary iron at each side of the
longitudinally-reciprocating iron, the goods are held smooth upon the cylinder
and are not liable to be creased whilst undergoing the polishing action of the
reciprocating iron.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. In an ironing machine, the combination, with the revolving cylinder, of two
stationary irons and one longitudinally-reciprocating iron working between the
other two, as described.
2. In an ironing machine, the combination, with the revolving cylinder, of two
stationary irons and a longitudinally-reciprocating iron guided between the other two
by crossbeads and horizontal gnides, as described.
3. In an ironing machine, the combination, with the revolving cylinder, of a
longitudinally-reciprocating iron and of two stationary irons, the former being guided
between, and connected to, the two latter by crossheads and guides and the two
latter being held stationary by vertical guides which permit of the irons being
raised off the cylinder, as described.
4. In an ironing machine, the combination, with the reciprocating and stationary
irons connected and guided as described, of treadle-operated mechanism for raising
the irons, substantially as described.
