Improvements in Mangling or Ironing Machines.
I, MENZO EDGAR WENDELL of No. 648 Fulton Street, Troy, in the County of
Rensselaer, and State of New York, United States of America, Gentleman, 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:-
This invention relates to mangles of that class which are adapted to operate upon
first one side and then on the opposite side of the material. Among the various
objects in view are to give strength and rigidity to the frame-work, at the same
time reducing its complexity and cost of manufacture, to provide a system of
gearing which applies power to both ends of the ironing and clothed rolls, and to
provide such a system and arrangement of such rolls as will give an extensive
heated surface to the principal ironing roller in connection with spaced clothed rolls
which permit of periods of evaporation during the process of ironing and a subsequent
ironing of the opposite side of the fabric, which is a part of the continuous operation
of the machine. Further objects in view involve the provision of readily-operated
mechanisms for operation the principal ironing roll from the series of clothed rolls
cooperating therewith and for the separation of the final ironing roll from its
companion clothed roll.
The invention also provides doffer blades and guiding surfaces to direct the
material from one portion of the machine to the other.
Other objects and advantages of the invention will appear in the following
description, and the novel features thereof will be pointed out in the claims.
Referring to the drawings:-
Fig. 1 is a right end elevation of a mangle embodying my invention,
Fig. 2 is a left end elevation of the same.
Fig. 3 is a rear or delivery end elevation of the machine, broken centrally and
vertically with the inner ends of the rolls and adjacent parts perspectively
extended.
Fig. 4 is a detached skeleton illustration of the mechanism employed for raising
and lowering the principal and primary heated drum or roll.
Fig. 5 is a similar view of mechanism employed for raising and lowering the
final or secondary heated roll.
Like letters refer to like parts in all the figures.
A A represent standards which are provided with suitable bearing-box and
journal receptacles for the moving parts and with apertured bosses A', for the
reception of tie-rods A2, which may be either hollow or solid and which are right
and left screwthreaded for connection with bosses and have set-nuts A³, whereby
the standards may be maintained a proper distance apart and parallel with each
other. A bracket A', is secured to one of the standards and is provided with a
bearing A, for the pulley shaft A', by which power is applied to the machine.
Upon the bracket A', and arranged cross-wise is an arm A, which has at each
extremity a bearing-box A, for the reception and operation of one end of a belt-
shifter A, the opposite end of the belt-shifter being mounted in a bearing A,
formed on or it may be secured to the standard A. The belt-shifter Aº, is provided
with a pair of belt-guides A", adjustably secured in movable sockets A", which
are themselves adjustably mounted upon the shifter. The arrangement of the
shifter as shown in Fig. 1 is such as to receive a belt upon the right of the belt
pulleys Ax, one of which as is usual, is loosely mounted on the shaft A. If it be
desired to receive the belt from the left of the pulleys, then the shifter A', is placed
in the bearing A³, at the opposite end of the arm A', and in a companion bearing A",

page_text: formed upon or secured to the standard A, in line with said bearing A³. The
adjustable connection of the guides A", is such that they can be elevated or
depressed as to bestride the belt at any angle it may take in approaching and passing
upon the pulleys.
The belt-shifter is operated by a hand lever B, which is at the right side or end
of the machine and within easy access of the operator that feeds the material, to
the machine. This lever B, is rigidly connected with a rock-shaft B', having a
rock-arm B³, connected by a slot and pin at its free end and with the shifter A'.
Bearings B are formed on the standard for the rock-shaft and the rock arm B³,
may be mounted either at the end of the shaft as shown, or at a point between its
bearings which shall bring it in connection with the shifter when shifted to the
bearings AB, at the left of the pulleys. The bracket A', is secured to the standards
by bolts A¹×
At this point of the description, it is convenient to explain the modified manner
of connecting the tie-bars or tubes A2, with the upper portions of the standards A.
Instead of being threaded into the standards the tic-tubes or rods are threaded into
brackets A, which are secured to the standards; these brackets while they give a
broader and stiffer connection of the parts also leave the standards unobstructed at
a point in the axial line of the tie-tube or rod and this point is utilized for the
locations of the studs 6 and stud-retaining bolts 6*.
C represents the principal or primary heated roll or drum of the machine, about
a portion of the periphery of which are a series of clothed rolls D, spaced so as to
provide for the evaporation of the dampness of the goods being ironed as they pass
from one to the other clothed roll of the series. The journals of the roll C, are
hollow for the purpose of the introduction of steam and they may be exteriorly
screwthreaded as shown at C¹, Fig. 3, for the proper connection of suitable con-
ductors for carrying steam into an exhaust steam from the roll. The journals of
the rolls D, are suitably mounted in boxes D', dotted lines Fig. 2. In Fig. 1,
there is a sliding box D¹, shown in full lines and as it is mounted in the frame and
controlled or adjusted in like manner to the boxes of the rolls D, a description
thereof will be given with particular reference to Fig. 1. The frame A, is provided
with a square recess in which the box may slide and this recess is bridged by a
cap D', secured to the frame or standard by screws or bolts D³. There is threaded
in the cap a hand-wheeled-bolt D, and between the head of this bolt and the
sliding box there is interposed a coiled spring D'. There is provided at each end
of each of the rolls such a cap, bolt and spring so that the pressure and proper
alignment of the clothed rolls with the heated roll or drum C, may at all times be
secured. The last clothed roll D, of the series is not intended to contact with the
principal heated roll or drum C, but with the final or secondary heated roll E,
which is regulated so as to its contact with the clothed roll D, in the same manner
and by similar means as that employed on the clothed rolls D, above described.
F is the feed-board upon which goods are placed when they are fed into the
machine; it has upon its upper surface a sheet metal guide-plate F1, that projects
beneath and is curved to conform more or less with the periphery of the first
clothed roll. The feed-board F, is pivotally connected at F', with the goods-box G,
and the latter is adjustably connected with the standards by means of projections G¹,
one at each end of the box which ride in a bearing G³, formed on the frame and
covered by a bar G³, and having an adjusting bolt G', by which the box may be
raised or lowered and by the pivotal action of the feed-board F, therewith, the
front edge or portion of the curved feed-plate F¹, is brought nearer to or further
from the clothed roll D, as desired when ironing goods of varied thickness and to
insure a forward movement of the goods by the roll D. The feed-board F, is
suspended by brackets F2, which hang from a rod F³, extending across the machine
and over the feed-board. The goods-box G, is pivotally supported by the pro-
jections G¹, and is provided with a bolt G', which rests against the edge of the
standard. There is a bolt at each end of the goods-box. These bolts G³, serve
the purpose of adjusting the bent portion of the feed-plate F¹, with relation to

page_text: the periphery of the primary heated roll and that independently of the adjustment
of the guide plate with relation to the clothed roll.
H is a doffer-blade which extends from side to side of the machine and along
the primary heated roll from end to end; this doffer is a comparatively thin steel
plate at the ends of which are secured heads H', terminating in bolts H', which
At one end
pass through the standards and are provided with nuts H³, Fig. 1.
of the doffer the bolt H2, is encircled by a coiled spring H*, see dotted lines at the
right of Fig. 3, which spring impinges against the standard and on its outer surface
and against the inner surface of the bolt so that the edge of the doffer bears
yieldingly against the surface of the roll C so as to strip the goods therefrom
and it is inclined so as to direct said goods between the final heated roll E, and the
final clothed roll D, from which the goods are by a delivery plate I, guided onto
the delivery table or shelf J, of the machine.
The means for raising and lowering the principal or primary heated roll C, into
and out of contact with the series of clothed rolls D, consists of a pin K, one at
each end of the roll and each arranged to bear against the lower side of the box C',
in which the journal of the roll C, rotates. Below the pin there is pivoted in the
framework at K', a sector-cam K, the face of which makes contact with the
pin K; the sector cam is bifurcated and the shorter bifurcation K, takes bearing
on the outside of the standards on the pivot K', while the longer bifurcation K',
takes bearing on said pivot K', on the inside of the standard and is extended
downward in the form of a toothed sector K. It is understood that there are two
sector cams in the machine, one mounted in each standard, and that each sliding
box of the roll C, is operated by said cams and the interposed pins. K is a shaft
extending from one standard to the other and provided with pinions K', which
mesh with the cam-sectors K'; the shaft K, is extended through the standards
and is provided with a geared sector, with which a worm K, upon a shaft K,
meshes. A hand-wheel K", is provided for rotating the shaft K. Now it will
be seen that by means of the hand wheel K", and the connecting devices just
described the heated roll may be readily elevated or depressed so as to regulate
the pressure to which the goods shall be subjected and to remove the heated roll
from the clothed roll when the machine is not actually in operation and thus
prevent scorching the clothing of the rolls D.
The means employed for separating and bring together the final heated roll E,
and clothed roll D consists of a shaft L, provided with a hand wheel L', and a right
and left screwthreaded portion L³, at each end respectively. Boxes L³, are
provided for supporting the shaft L, in the standards and at points beyond and at
each end of its threaded portion, thus strengthening that portion at each end of
the shaft to withstand the pressure brought to bear thereon. A nut L', having
trunnions L, is mounted on the threaded portion of the shaft so as to travel
therealong when the shaft is turned. On a pivot M, which passes through
brackets H', depending from the standards there is mounted a cam N, which is
provided with an arm N', which is bifurcated to embrace the nut and again to
embrace the trunnions of the nut. A pin O, extends upwardly through the
standard and bears against the under surface of the box of the clothed roll D, with
which the heated roll E, co-operates. It is understood that there are duplicate
cams and pins, one under each box of the roll so that by turning the hand wheel L',
in one direction the boxes are raised while they are lowered by turning the said
wheel in the opposite direction.
My invention is not limited to any particular system of gearing for giving the
desired movement to the several rolls but I have illustrated a duplicate system of
gearing whereby power is conveyed to the opposite ends of each of the rolls.
Power is applied to the shaft A', by means of the pulley Ax, and on this shaft is
a pinion which meshes with a master gear 2 on a shaft which extends through
both standards and passes under the feed-board and back of the goods-box and has
upon its opposite end a gear 3*, Fig. 3. Inside of the gear 2, there is a pinion 3,
which meshes with the large gear 4, mounted on the shaft of the drum or roll G.

page_text: An idle gear 5, Fig. 1, meshes with the pinion 3, and with the gear 6, of the first
clothed roll of the series; the remaining rolls are rotated by means of the following
gears of the series, viz., 7, 8, 9, 10, 11 and 12, those bearing odd numbers being
intermediately mounted on bridges P, secured at each end to the bearings formed
in the standards for the reception of the sliding boxes of the various rolls. By
referring to Fig. 2, the system of gears connecting the opposite ends of the rolls
will be plainly seen; the gear 3*, meshes with the intermediate gear 5*, and the
remaining gears and the intermediates being indicated in said figure as follows:-
6x, 7, 8, 9, 10x, 11x and 12× the intermediates being mounted on bridges P.
The roll C, is provided with a large gear 4*, which meshes with a pinion 13
whose companion gear 14, meshes with the gear 15, on the last of the clothed rolls,
and this latter gear meshes with the gear 16, mounted on the secondary or final
heated roll.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed, I declare that what
