IMPROVEMENTS IN ROLLER MANGLES
Year: 1885

page_text: I, EDWIN GILLARD CAMP of 2 Grove Park, Redland Road, Bristol in the
County of the same City, retired Brush Manufacturer, do hereby declare the nature
of my invention for "IMPROVEMENTS IN ROLLER MANGLES" to be as follows :—
And consists in combining the principle and advantages of the Box Mangle with
those of the more convenient and portable Roller Mangle.
The Box Mangle provides that the articles to be mangled shall be wrapped
around rollers of comparatively small diameter and submitted to a rolling process
between plane surfaces, the upper one being heavily weighted and pressing by
gravitation on the rollers beneath it: thus, smoothing or mangling the clothes.
In Roller Mangles, rollers of equal size are made to rotate synchroniously-
pressure being applied by springs or weights to press one of the rollers against the
other. In this condition, clothes are made to pass between the rollers and are thus
pressed or mangled to a smooth surface. No doubt is entertained but that the
Box Mangle does its work better than the Roller Mangle now in general use, but
in my Invention, I combine the efficiency of the Box Mangle with the smaller
and more convenient Roller Mangle in the following or substantially similar
mauner,
Between suitable standards I hang a roller of suitable size and material on
bearings which slide up and down in slots provided in the standards for that
purpose. The material and form of these bearings is elongated sufficiently to
receive also the bearings of a pinion wheel which gears into a spur wheel fixod on
the end of the roller: this arrangment permits considerable vertical vibration of
the roller without throwing the pinion and spur wheels out of gear. A handle or
handles fixed to tho pinion wheel or to a fly wheel connected therewith commu-
nicates motion to the roller. This roller, which I shall call the pressure-roller, is
made to receive pressure either by a spring or springs or a weight or weights,
either external to or internal to the roller.
Now I take another roller like an ordinary Box Mangle roller, (which I shall
call the clothes-roller) and having wrapped the clothes to be mangled round it just
as it is done for the Box Mangle, I place it (the clothes-roller) in contact with the
pressure-roller and turn the handle: this movement immediatly rolls the clothes-
roller into its place under the pressure-roller and by continuing the motion by the
handle (or otherwise) the clothes-roller continues to be rotated and the clothes to
receive pressure,

page_text: To give this clothes-roller the facility to rotate with little friction from and by
its contact with the rotating pressure-roller, it is made to rotate on roller bearings
at both of its ends. When the clothes are sufficiently mangled, the clothes-roller
is rolled out from under the pressure-roller by reversing the motion of the handle,
another roller wrapped round with clothes is placed in position and the work
proceeds as before.
When I employ a pressure-roller of large diameter I sometimes build it up of
staves dowelled and glued together, and further secured and strengthened by
cast-iron heads or ends bolted together from end to end. I bevel the ends of the
roller thus
which bevels fit into corresponding grooves in the iron ends so
that tightening the bolts compresses the staves together. It is sometimes con-
venient to fill the interior of this pressure-roller with weighty substances to give
it the requisite weight or to place a spring or springs inside the roller and lead the
power out through a hollow shaft to exert a downward pressure on its exterior.
I claim as new in this my Invention-
Firstly. The connecting the bearings of the pinion and spur wheels when
applied to Roller Mangles in such a manner that they remain in contact and work
together whilst the pressure-roller is vibrating up and down.
Secondly. The application and employment of loose rollers (which I shall call
clothes-rollers) to Roller Mangles as distinguished froui Box Mangles which loose
rollers have hitherto been applied only to Box Mangles.
Thirdly. The use of roller bearings applied at the ends of the loose or clothes-
rollers in Roller Mangles.
Fourthly. The building up of large size rollers by staves, fastened together by
means of dowells and glue or similar suitable material and covering their ends
with iron plates of suitable shape as before described.
Fifthly. To make the pressure-roller, when found to be convenient to do so, to
carry within itself the necessary spring or weight force to give to it the desired
downward pressure as before described.
I also claim to employ if I think fit, a treadle arrangment in lieu of or in
addition to the handle or handles for imparting motion to the pressure-roller.
I claim to make all the parts of this my Invention of such material or materials
as in practice proves best and most suitable.

page_text: I, EDWIN GILLARD CAMP of 2 Grove Park, Redland Road, Bristol in the
County of the same City, retired brush manufacturer do hereby declare the nature
of my invention for IMPROVEMENTS IN ROLLER MANGLES and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :—
In Roller Mangles as hitherto made, rollers are made to rotate synchroniously,
pressure being given by springs or weights to press the rollers together: clothes are
then passed between the rollers and are pressed or mangled.
In the case of Box Mangles, the clothes to be mangled are wound round loose
(clothes) rollers and submitted to a rolling process between plane surfaces by
moving the upper one (a box heavily weighted) to and fro.
In my Improvements I apply the loose (clothes) roller and the weighted box of
the cumbrous and costly Box Mangle to the more portable and convenient Roller
Mangle in the following or substantially similar manner.
In Box Mangles, loose (clothes) rollers are made to rotate between plane surfaces:
in my invention the loose (clothes) roller is made to rotate against a rotating
cylindrical surface or between rotating cylindrical surfaces :-again, in the Box
Mangle the weighted box is made to oscillate to and fro over the loose rollers, in
my invention this weighted box is hung on the elongated vibrating bearings which
carry the top roller &c.
I have many ways of arranging the details of my mangle, I will now describe
and illustrate the one which presents the most familiar form, viz: its application to
an ordinary Roller Mangle:-thus:-I seperate the top (vibrating) roller from the
bottom roller by some 3 or 4 inches, in other words, by the diameter of the loose
(clothes) roller about to be employed: I take now this loose roller, wrap round it
the clothes to be mangled, place it in contact with the other two rollers and set
them in motion. If the top (vibrating) roller has been stationed at the requisite
distance from the bottom roller the clothes roller will be immediatly drawn into
its place between them. To prevent its going too far or rolling out again before
required to do so I place roller bearings at each end of the clothes roller, which are
removable at will.
Pressure by gravitation in Roller Mangles is obtained by hanging weights on
long levers or arms in connection with the pressure roller, when I employ
gravitation to do this work I extend the bearings which carry the top roller to
a position below the bottom roller: at or near this point I hang on said bearings
a box, which when the mangle is set up ready for use I fill with stones and other
weighty substances.
I sometimes place the loose roller at the top-sometimes at the bottom of one
pressure roller-sometimes between two rollers (shewn in figs. 1 and 2) and some-
times between three rollers, but in all cases it is only a difference of detail, the
principles involved being the same.
Sometimes it is convenient to employ a pressure roller of large diameter, in
whịch case I build it up of staves securely glued and fastened together and further

page_text: strengthened by wedge-shaped metal heads or ends bolted together longitudinally:
shewn sectionally in fig. 3. Sometimes also it is convenient to obtain and employ
gravitating pressure direct from the pressure roller just described, in which case
I fill the built-up roller with weighty substances and convert the whole into one
mass by melted sulpher or other similar suitable material.

Having now particularly described and ascertained the nature of my said
invention for "Improvements in Roller Mangles" and in what manner the same
is to be performed I declare that what I claim is
Firstly. The application and employment of loose (clothes) rollers to Roller
Mangles, which loose rollers have hitherto been used to Box Mangles only.
Secondly. The use and employment of elongated or otherwise-connected
bearings by means of which the motive wheels, the pressure or top roller and the
weight-box are all hung to and work connectedly together.
Thirdly. To build up mangle rollers when required to be of large diameter of
staves secured together in manner described or in any other substantially similar
manner,
Fourthly. To make such large-sized rollers when convenient or desirable, to
carry within themselves the necessary weight force to act as pressure rollers.
I also claim to employ if I think fit a treadle arrangment in lieu of or in
addition to the usual hand appliance for giving motion to Mangles:-to make all
the parts of my "Improvements in Roller Mangles" of such material or materials
found most suitable-to vary the configuration and arrangment of the several
parts and to employ one or more of my Improvements in the construction of
any one mangle.
In my Provisional Specification I claimed as follows:-"The connecting the
bearings of the pinion and spur wheels when applied to Roller Mangles in such a
manner that they remain in contact and work together whilst the pressure roller
" is working up and down."
"
This particular claim I now disclaim as being incomplete in description and as
there described not new: what I do claim is more completely embodied under the
heading "Secondly."
