Improvements in Mangling or Ironing Machines.
I, ADAM KREUTER, of 44, S. Clinton Street, in the City of Chicago, County of
Cook, State of Illinois, United States of America, Manufacturer, 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 that type of machines of the class named, in which
a padded cylinder is employed in conjunction with steam chests, garments to
be ironed being passed between the cylinder and the faces of the steam chests;
and the objects of the invention are to improve machines of this type by pro-
viding the steam chests with suitable supports by which they may be adjustably
held in proper relation with the cylinder; and to provide improved means for
bringing the steam chests into action. A further object is to provide means for
drying the fabric with which the cylinder is covered.
These several objects are attained in the construction hereinafter fully
described, and which is illustrated in the accompanying drawings, in which
Fig. 1 is a side elevation of the machine, partly in vertical central section;
Fig. 2 is a detail section on the line 2-2 of Fig. 1;
Fig. 3 is a detail section on the line 3-3 of Fig. 1;
Fig. 4 is a transverse vertical section on the line 44 of Fig. 1; and
Fig. 5 is a detail of a joint used in the machine.
The machine, generally speaking, comprises a frame upon which is journaled
a cylinder, as B; a pair of segmental steam chests, H, K, being mounted con-
centrically with the cylinder, and supported upon sliding bearings upon which
they may advance towards or be withdrawn from the cylinder, suitable levers
being provided for controlling such movements.
The frame comprises the two end standards, A, A, and the side rails, a,
uniting these standards. At their upper ends the standards are provided with
suitable boxes upon which is journaled a shaft, C, upon which is fixed a cylin-
der. B which is made of sheet steel, freely perforated, and supported by the
spiders, b, fixed upon the shaft. The cylinder B is enveloped in a textile or
felt pad, bl.
Power is applied to rotate the cylinder by means of a belt pulley, D, fixed
upon a shaft, d, journaled longitudinally as to and extending the entire length
of the frame, and carrying pinions, d, one adjacent to each end, which pinions, d¹,
intermesh with gear wheels. E, which are mounted upon shafts, e, projecting
outwardly from the standards, A, the hub of the gear wheel E being prolonged,
and comprising a pinion, el, which intermeshes with the gear wheel F fixed
upon the shaft C; this train of gears is in duplicate, one at each end of the
machine, in order that the strain may be more evenly applied.
A steam coil is located within the cylinder B, and, as shown, comprises a
plurality of longitudinally disposed steam pipes, G, one between each pair of
spokes of the spiders b. Steam is served to this system of piping through a
steam pipe, c, which may be located at either end of the machine, and which

page_text: enters a suitable longitudinal aperture formed in the end of the shaft C, a
stuffing box, 2, being applied to the end of the shaft in order to make a steam
tight joint while permitting the shaft to rotate relatively as to the pipe c.
Connection is made between the tubular portion of the shaft C and one of the
steam pipes G, as shown at g, and at its farther end this steam pipe G is united
with one of the adjacent pipes of the same character, as shown at which in
turn is similarly united at its farther end to its next neighbor, this series of
connections being continued so as to connect the entire system of tubing, and
the last pipe, G, being connected with a suitable longitudinal aperture in
the end of the shaft C opposite to that at which the steam enters, which aperture
in turn is connected with the discharge pipe c¹, in the same manner as the
connection is formed with the pipe c. The cylinder B being perforated, a circu-
lation is provided through the covering pad b, and as a result this pad is kept
dry. I believe myself to be the first to apply heat to the interior of an open-
ended perforated cylinder for the purpose of drying its envelope by the direct
action of the heat and by the circulation of air directly stimulated thereby.
Usually machines of this type are entirely unprovided with means for drying
the cylinder envelope. I am aware that it has been proposed to set up circu-
lation of air through the envelope by applying suction to the interior of the
cylinder, but this is inefficient even though heat may be introduced into the
cylinder for the reason that the air drawn through the envelope is necessarily
comparatively cool and hence lowers the temperature of the envelope, thereby
not only checking evaporation but robbing the steam chest of heat which should
be applied directly to the goods.
The steam chests, H, K, which co-operate with the cylinder are segmental in
form, their inner faces being polished for application to the goods, and being
concentric with the cylinder B, these chests are of the same length as the
cylinder. The frame of the machine is provided with suitable brackets, as P,
for supporting the steam chests, and preferably the supporting faces of these
brackets are flat, and in the plane of radii of the cylinder, two of such brackets
for each of the chests being provided, one at each end of the machine. As usual
in machines of this type, one of the steam chests, H, is set at a greater elevation
than the other, K, for convenience of feed and delivery, the goods being fed to
the machine from a table, as V, carried by the chest, H, and discharged there-
from at the upper edge of the chest K, which carries a table, W, upon which they
may be deposited. The lower edges of the steam chests overlap, as shown at X,
so that when they are brought up to position for service a continuous surface is
presented for bearing against the goods as they are carried along by the cylinder.
Each of the chests is provided with co-operating brackets, h, k, adapted to rest
and slide upon the brackets P, and for the purpose of securing durability, and
also for the purpose of providing for a proper adjustment of the chests relatively
as to the cylinder, a shoe, h¹, is interposed between the brackets, h, k, and the
brackets P. This shoe should be loosely connected to one of the co-operating
brackets; as shown this connection is with the chest bracket, and is accomplished
by the use of dowel pins, h², preferably fixed in the shoe, and loosely entering
suitable sockets in the bracket. A pair of adjusting screws, h³, passes through
the bracket with which the shoe is connected, so as to bear upon it. While I
have shown the shoe as connected with the chest bracket, it is obvious that it
might be connected with the frame bracket, and in the latter event the adjusting
screws, will be correspondingly changed. By turning down the adjusting
screw, nearest to the chest, it will be seen that the lower edge of the chest
will be thrown inwardly towards the cylinder, while the setting up of the outer
adjusting screw will result in tilting the chest in the opposite direction, so that
its upper edge will be thrown more nearly to the cylinder. The details of con-
struction for the support of the two chests being the same, I have not deemed
it necessary to describe and fully illustrate more than one.
The movement of each of the steam chests is controlled by a pair of lever

page_text: arms, M, O, one member of each pair being located at each end of the cylinder.
These lever arms, M, O, are pivotally mounted upon a shaft, Q, which, for the
sake of greater strength, runs the entire length of the machine, and this
shaft is supported upon the frame preferably by means of brackets, q, in arch
form, supported by the side rails, a. The connection between the lever
arms, M, O, and the steam chests being identical in form, I have shown in
detail only one. The arm M is pivoted to lugs, m¹, m³, formed upon the
outer face of the chest H. As the end of the arm M oscillates, with the
shaft Qas a center, while the movement of the chest H is a reciprocation
upon a right line, in the construction shown, compensation for the diverging
of the paths of the two parts is provided for by making the aperture in one of
the parts larger than the pivot-pin m², which unites the arm M with the lugs m¹.
This lost motion does not interfere with the proper action of the machine, while
fully serving the purpose in view.
Each of the lever arms, M, O, has a downwardly projecting arm, m, o, and
between them there is located a cam, R, mounted upon a shaft, r, journaled in
the standards A, A. and controlled by means of a hand lever, S." When the
cams R are turned to spread the arms m, o, the steam chests H, K, are forced
toward the cylinder B. A segmental ratchet, U, is fixed upon the shaft r, and
with it co-operates a gravity pawl, u, which prevents the recession of the parts
when the steam chests are advanced toward the cylinder. Upon the release of
the pawl and the throwing back of the cam R, the steam chests fall away from
the cylinder, their supporting brackets being inclined downwardly at their
outer ends.
It is necessary in machines of this character that the polishing surfaces be
held to the cylinder by yielding supports, and this is provided for by setting trans-
versely through each of the armis, m, o, a reciprocating flat headed bolt, T,
against the head of which the cam R bears, and encircling the stem of the
bolt with a coil spring, t, the aperture provided for the bolt being counterbored
to accommodate the spring.
As thus constructed the parts of the machine may be easily adjusted, and always
kept in proper relation, any wear of the bearing parts being easily compensated
for by a readjustment by means of the screws h³.
The chests, H, K, are supplied with steam by means of a pair of pipes, Z,
leading one to each of the chests, and being capable of sufficient oscillation to
permit of the movement of the chests in the manner described.
