of Nottingham, for an Invention of "IMPROVEMENTS IN IRONING MACHINES
PROVISIONAL SPECIFICATION left by the said Leonard Lindley at the
Office of the Commissioners of Patents on the 7th May 1880.
LEONARD LINDLEY, of the Town and County of the Town of Nottingham.
"IMPROVEMENTS IN IRONING MACHINES WHICH MAY ALSO BE USED FOR DRYING."
The Invention has for its object improvements in ironing machines which may
also be used for drying.
For this purpose I employ a heated cylinder and three guide or tension rollers.
Two of these guide or tension rollers are in contact or nearly so with the hented
cylinder, and the other is at a short distance therefrom. Around the cylinder and
tension rollers is passed an endless ironing cloth or apron, in such manner that
the said cloth or apron passes about two thirds around the surface of the heated
cylinder, and then passes away therefrom around the three tension rollers.
One of the tension rollers is provided with regulating means, whereby tension
may be put on the ironing cloth or apron in order to keep the latter in close
contact with the heated cylinder.
The ironing cloth or apron is conducted in guides at its edges in order to keep it
fully distended.
If desired more than one heated cylinder, and more than three tension rollers
may be employed, in which latter case the ironing cloth or apron may extend
around nearly the entire cylinder, and if desired the machine may be combined
with any suitable tentering machine from which it can receive the fabric to be
ironed or dried.
Upon giving motion to the heated cylinder, the ironing cloth or apron passes
over about two thirds or more of the surface of the heated cylinder, and thence
around the tension rollers. The fabric or articles to be ironed or dried is or are
placed against the heated cylinder and conducted by the ironing cloth or apron
around the heated surface thereof. The tension put on the ironing cloth or apron
presses the fabric or articles to be ironed or dried closely to the surface of the
heated cylinder.

machine, and the roller d' is carried in bearings formed in a frame k pivotted at /¹
to a weighted lever arm l, which is pivotted at to an arm m fixed to the bracket j,
by which means an elastic pressure is put by the said roller d' upon the ironing
cloth or apron c, thereby permitting varying thicknesses of material readily to pass
between the rollers d, d, d', and yet maintaining a suitable tension upon the
ironing cloth c.
And in order to assist in retaining the ironing cloth c properly distended upon
the cylinder a, I make the surface of one or more of the tension rollers b, b¹, b², b³,
in the form of a right and left handed screw, thereby in the rotation of such roller
or rollers spreading out the ironing cloth c, as will be readily understood.
In Figure 1 the fabric to be ironed or dried is represented as being delivered to
the ironing or drying machine from the chains of pins or hooks n of a tentering
machine, in which case a surface speed must be given to the cloth or apron c
similar to that given to the chains n.
The ironed or dried fabric is received on to a moveable table or board o.
If desired a greater surface speed can be given to the heated cylinder a than
that given to the ironing or drying cloth c, in order that a polishing effect may be
imparted to the goods under treatment, and if desired more than one heated
cylinder a may be employed, in which case suitable guide rollers must be used to
cause the cloth or apron c to follow the surfaces of such heated cylinders.
The cylinder a and the rollers b, 62, 63, are mounted in fixed bearings carried by
suitable frames; I have not however thought it necessary to show such frames,
nor the method of giving motion to the cylindrical rollers, as such will be readily
understood by a competent mechanic.
Having thus described the nature of my said Invention and the mode in which
I carry the same into effect, I would have it understood that what I claim is, the
employment in ironing machines of one or more heated cylinders a, tension
rollers b, 61, 62, 63, endless cloth or apron c, and distending rollers d, d, d', all
arranged and operated in manner and for the purpose substantially as herein
described.
In witness whereof, I, the said Leonard Lindley, have hereunto set my band
and seal, this Third day of November, in the year of our Lord One.
thousand eight hundred and eighty.
