An Improved Mangle.
I, WILLIAM SHEDLOCK, of 61 Strathblane Road St. Johns Hill, Wandsworth, in the
County of Surrey, Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to mangles and more especially to mangles of that kind or
class in which several auxiliary rollers are employed in conjunction with the main
roller.
My said invention is designed to provide a more efficient mangle of the kind or
class above mentioned than has been hitherto constructed, and comprises various
improvements hereinafter set forth.
In carrying my said invention into practice I provide a suitable metal or other
frame. In this frame I arrange horizontally a main cylinder or roller, the gudgeons
of which are carried in suitable bearings in the said frame. The main roller is
moreover formed hollow and provided with suitable connections by means of which
gas steam, hot air, or the like, may be supplied to the interior of the said hollow roller
for heating purposes. I provide moreover three or other suitable number of auxiliary
rollers placed parallel to the main roller, and which bear against the periphery of the
said main roller. The gudgeons of the said auxiliary rollers are carried in suitable
bearings provided in blocks fitted to slide freely in ways or slides in the frame of the
machine, arranged radially to the axis of the main roller, so that the said auxiliary
rollers can move freely to or from the same. The said blocks are provided with
extensions having grooves adapted to carry a wire or other suitable rope or a chain on
either side of the said rollers. The extremities of the said ropes are securely fixed at
either end of a cross piece arranged to slide vertically in ways or slides provided in
the frame. Antifriction rollers arranged to turn freely upon studs or pins attached to
the frame or other suitable means are provided for guiding the said ropes and main-
taining the same in a convenient position. I provide morcover a cross piece rigidly
fixed to the frame of the machine above the hereinbefore described movable cross-
piece. The said fixed cross piece is provided with a central boss having a
screw-threaded hole in which is adapted to fit a correspondingly screw threaded spindle
provided at its upper extremity with a suitable hand wheel, and at its lower extremity
with a collar adapted to bear against a spiral spring fitted upon the movable cross
piece. By turning the hand wheel so as to cause the screw threaded spindle to
compress the said spiral spring, any desired amount of pressure can be applied to the
movable cross-piece and through the hereinbefore mentioned wire or other ropes
communicated to the auxiliary rollers so as to cause them to bear more or less against
the periphery of the main roller.
I sometimes provide a covering for the main roller formed of a blanket or other
suitable material. I prefer to employ a cover in the form of an endless band or belt;
and I provide an idler roller to maintain the said cover taut upon the main roller.
In this case I form the auxiliary rollers hollow and provide suitable means for heating
the same.
I may employ any suitable gearing for driving the rollers of my improved mangle,
and arrange the same to be worked either by hand or power. I prefer however to
cause the upper or auxiliary rollers to travel faster than the main roller thus
producing more friction and consequently ensuring better results.
Although I have herein before described a convenient and advantageous inethod of
carrying my said invention into practice, it is obvious that I can somewhat modify
the construction of my improved mangle without however in any way departing from
the nature of my said invention. For instance I can form the main roller solid

ispense with the arrangement for heating the same. Instead
ends of the movable cross-piece I can join the said rope so as to form an endless ropo
and pass the same underneath the said movable cross-piece. Moreover instead of
employing a spiral spring to obtain the required pressure upon the movable cross
piece I can employ a coach spring, or any other suitable spring or springs, or an
arrangement of weights or of weights and levers.

My invention relates to mangles of the kind or class wherein several auxiliary
rollers are employed in conjunction with the main roller, and my said invention
comprises various improvements hereinafter set forth.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1, is a front elevation partly in vertical contral section.
Figure 2 is a side elevation, and
Figure 3 is a transverse section on the line x, x, Figure 1, showing one form of my
improved mangle.
Like letters indicate corresponding parts throughout the drawing.
A is the frame of the machine, A', A' are the tables or guides for supporting and
directing the articles passed through the machine.
B is the main or lower cylinder or roller, and B', B' are the upper or auxiliary
cylinders or rollers; CC are the pulleys receiving motion by means of belt-gearing
from any convenient source of motive power. The said pulleys are carried upon a
stud fixed in the frame A and are free to rotate thereon. D, D1, D2, D3 are
toothed wheels for communicating rotary motion to the operating cylinders or
rollers B, B¹.
The lower or main cylinder or roller B and the upper or
rollers B are preferably hollow and formed of metal. The lower or main cylinder or
auxiliary cylinders or
roller B is provided with gudgeons a by means of which it is supported in suitable
bearings a' in the frame A. One of the gudgeons
frame A and has firmly keyed or otherwise secured thereon the toothed wheel D'
a is extended through the said
which gears with the toothed wheels D secured upon the gudgeons of the upper or
auxiliary cylinders or rollers B' as hereinafter described, and the toothed wheel D²
which gears with the toothed wheel or pinion D³ which is either firmly attached to or
formed in one with the boss of the pulley C.
The said lower or main cylinder or roller B is morcover provided with a covering
formed of blanket or other suitable material. Or the said blanket may be arranged in
the form of an endless band or apron carried upon the said main cylinder or roller
and upon an idler roller provided for that purpose. The other or auxiliary hollow
'metal cylinders or rollers are placed parallel to the main cylinder or roller, and bear
against the periphery of the latter. The said cylinders or rollers B' are provided
with gudgeons by means, of which they are supported in suitable bearings provided
in blocks c fitted to slide freely in ways or slides d in the frame A.
slides d are arranged radially to the axis of the lower or main cylinder or roller B so

adapted to fit wire or other ropes or chains e arranged on either end of the said rollers.
The extremities of the said ropes or chains e are securely fixed at either side of the
machine to a cross-piece fas more clearly shown in Figure 3. The said cross piece f
is arranged to slide vertically in ways or slides 9 provided in the frame A. h, hare
anti-friction rollers which are arranged to turn freely upon studs or pins ¹ attached
to the frame A or other suitable means are provided for guiding the said ropes and
maintaining the same in a convenient position. I provide moreover another cross-
piece rigidly fixed to the frame A at a suitable distance above said movable or
sliding cross-piece f. The fixed cross-piece is provided with a central boss ¹ having
a screw-threaded hole in which is adapted to fit a correspondingly screw-threaded
spindle which is provided at its upper extremity with a suitable hand wheel k and
at its lower extremity with a collar or disc adapted to bear against one extremity of
a spiral spring m, the other extremity of which is supported upon the movable or
sliding cross-piece f. By compressing the said spiral spring m to a greater or less
extent by means of the hand wheel & and screw threaded spindle any desired amount
of pressure can be applied to the movable cross-piece f, and thus through the herein-
before mentioned wire or other ropes e, communicated to the upper or auxiliary
cylinders or rollers B¹ so as to cause them to bear with more or less force against tho
periphery of the main or lower cylinder or roller B.
The gudgeons bon one side of the upper or auxiliary cylinders or rollers B¹ are
extended through the frame A and upon each of the said gudgeons is firmly keyed or
otherwise secured one of the toothed wheels D. The said gudgeons b on the other
side of the said upper or auxiliary cylinders or rollers are formed hollow, and I
provide any suitable well known, device for heating the said upper or auxiliary
cylinders or rollers by means of steam, hot air, or the like.
In some instances I construct the toothed wheels D which are keyed or otherwise
secured upon the gudgeons b of the said upper or auxiliary cylinders or rollers B' in
such a manner that each of the said toothed wheels will have successively one or more
teeth less than the one immediately preceding it. By this means I provide for
driving the said upper or auxiliary cylinders or rollers B' at different speeds. The
said upper or auxiliary cylinders or rollers B¹ morcover aro arranged, in this case, to
run at a higher speed than the lower or main cylinder or roller B. By this arrange-
ment a kind of slipping or dragging action of the said upper or auxiliary cylinders or
rollers takes place upon the articles being passed between the said cylinders or rollers,
thus causing more friction to take place and therefore rendering the operation more
analogous to that of ironing, and consequently ensuring better results.
I can moreover employ any convenient number of the said upper or auxiliary
cylinders or rollers B' in conjunction with the lower or main cylinder or roller B, and
any other suitable gearing for imparting motion to the said upper or auxiliary
cylinders or rollers, and to the main or lower cylinder or roller B.
In some instances I arrange my apparatus so that it can be worked by hand instead
of by power.
A mangle constructed according to my said invention has much fewer parts, and is
simpler in construction than thoso heretofore made, and is therefore less costly to
manufacture, and easier to keep in repair. The said mangle moreover is extremely
efficient in operation.
It is obvious that I can somewhat further modify the construction of my improved
mangle without departing from the nature of my said invention. For instance, I can
dispense with the arrangement for heating the upper or auxiliary cylinders or rollers,
and I can provide suitable means for heating the lower or main cylinder or roller, or
for heating all the said cylinders or rollers. Instead of attaching the extremities of
the hereinbefore mentioned wire or other rope or chain to the ends of the movable
cross-piece I can join the extremities of the said rope or chain so as to form an endless
rope or chain and pass the same underneath the said movable cross-piece. Moreover
instead of employing a spiral spring to obtain the required pressure upon the movable
cross-piece I can employ a coach spring, or any other suitable spring or springs, or an
arrangement of weights, or of weights and levers.

page_text: ng now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it understood
that I claim :-
First. In a mangle wherein two or more auxiliary cylinders or rollers are employed
in conjunction with the main cylinder or roller, the combination, with the said
auxiliary cylinders or rollers, of a spring or set of springs or an equivalent device
arranged to act upon all of the said auxiliary cylinders or rollers, to ensure the
requisite pressure thereof against the main cylinder or roller, for the purpose above
specified.
Second. The modification of my invention wherein I provide for driving the
cylinders or rollers at different speeds, substantially as, and for the purposo, set
forth.
Third. The improved mangle constructed with a single spring or set of springs
acting upon all of the auxiliary cylinders or rollers substantially as described with
reference to the accompanying drawing, and operating in the manner hereinbefore
specified.
