Improvements in Safety Appliances for use in conjunction with
Nipping, Presser, and Taking-in Rollers in Laundry and other
Machinery where such Rollers are Used.
I JOHN OLIVER trading under the style of David Bentley at Nortons' Court,
Greengate, Salford, in the County of Lancaster, Manufacturer of Bowls, do hereby
declare the nature of this invention to be as follows:-
My said invention relates to improved appliances or apparatus for use in con-
junction with nipping, presser and taking-in rollers in laundry and other
machinery.
When goods are fed by hand between such rollers it frequently happens through
carelessness or inattention that the operators' fingers are caught by the rollers and
his hand and arm drawn in so as to result in serious or fatal accidents. My inven-
tion has for its object to obviate such accidents. I provide a smaller auxiliary
roller which I place in front of the nipping or presser rollers so as to cover and
prevent direct access to the point of contact of the nipping or presser rollers.
This smaller roller is carried in a pivotted frame or in arms and is set by means of
adjustable stops so that it can move only a short fixed distance away from the
upper presser roller, or otherwise such a distance as will permit of the passage
of the goods but not sufficient to allow the fingers of the operator to pass
through.
The levers or frame carrying the safety roller are or is loaded sufficiently to
keep the safety roller against the upper presser roller. A guide behind the
safety roller directs the goods to the nipping point of contact between the upper
and lower presser roller. This guide might however in some instances be dispensed
with.
When using the invention the clothes or other goods are fed between the safety
roller and the upper presser roller and are carried forward to the point of nipping
or pressing contact between the upper and lower presser rollers. The movement of
the safety roller being fixed and adjusted, to a space less than the size of the
operators fingers it is practically impossible for the fingers to slip between the
rollers and thus accidents are obviated. The feeding might either be effected from
above as in the arrangement just described or it might be effected from beneath
the safety roller, which would in such a case be adjusted with reference to the
lower presser roller. To attain the same object I might arrange an inclined board
or surface to conduct the cloths to the point of contact of the presser rollers and
arrange a smaller pair of taking-in rollers at the top of the incline. The clothes
are fed between the said taking-in rollers and slip down the incline to the presser
rollers. The smaller taking-in rollers are adjusted so as to come only a small
distance apart but not sufficiently so to allow of the passage of the fingers of the
operator. I might also use an endless travelling apron or reciprocating table to
advance the clothes to the nipping or pressing rollers. I consider that the latter
arrangement of a travelling apron or reciprocating table is novel only as regards
laundry machinery.

Improvements in Safety Appliances for use in conjunction with
Nipping, Presser, and Taking-in Rollers in Laundry and other
Machinery where such Rollers are Used.
I JOHN OLIVER trading under the style of David Bentley at Nortons' Court,
Greengate, Salford, in the County of Lancaster, Manufacturer of Bowls, 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 and accompanying drawings:
--
My said invention relates to improved appliances or apparatus for use in con-
junction with mangling wringing calendering pressing or taking-in rollers in laundry
and other machinery.
When goods are fed by hand between such rollers it frequently happens through
carelessness or inattention that the operators' fingers are caught by the rollers and
his hand and arm drawn in so as to result in serious or fatal accidents. My inven-
tion has for its object to obviate such accidents.
I provide a smaller auxiliary guard roller which I place in front of the main
rollers so as to prevent direct access to the point of contact of the rollers. This
smaller roller is carried by brackets or in a pivotted frame or in arms and is set by
means of adjustable stops so that it can move only a short fixed distance away from
the bed roller or the upper roller as the case may be, or otherwise such a distance
as will permit of the passage of the goods but not sufficient to allow the fingers of
the operator to pass through.
My invention will be most clearly understood when described with reference to
the accompanying drawings.
In these drawings,
Fig. 1, illustrates the application of the guard roller to a pair of ordinary mangle
rollers.
Fig. 2, shows the formation of the bearing brackets and
Fig. 3, illustrates a modification.
In Fig. 1, ab are ordinary mangle rollers represented in section and c is the guard
roller which I apply as aforesaid. The roller c is provided with end journals which
pass through slots in brackets which are secured to the framing of the mangle. One
of these brackets appears at d and is separately represented by Fig. 2. The
bracket is formed with a slot which is inclined from the vertical and allows a limited
amount of "play" or movement of the guard roller from and towards the bottom
mangle roller b. In order that the amount of such movement may be capable of
regulation I provide the bracket with an adjustable piece d' which can be shifted
so as to shorten or lengthen the slot as may be considered desirable and when
adjusted is secured by means of a bolt. This formation of bracket is not a
necessary part of my invention and may be varied as considered to be desirable.
When the mangle is in use the articles are passed below the guard roller and are
carried forward between the two mangle rollers as is usual. In the event of the
fingers of the attendant passing between the guard roller aud the roller b the guard
roller ceases to revolve so that there is no tendency for the fingers to be drawn in
between the rollers.
It is intended that the movement of the guard roller in a direction away from
the roller shall be so limited as that the fingers of the attendant shall not pass
between the rollers b and c sufficiently far to be nipped between the main
rollers a and b.
If the fingers pass above the guard roller there is again no tendency for the
-fingers to be nipped and drawn in as the guard roller revolves in a direction contrary
to that of the upper mangle roller a.

page_text: In some cases it might be desirable to apply two guard rollers one at the back
and the other at the front of the machine.
In the modification illustrated by Fig. 3, the journals of the guard roller are
mounted to revolve in bearings formed in two links which are hinged upon studs
secured to the framing of the mangle one of these links being indicated by e. These
links would permit the guard roller to move from and toward the roller b as in the
first example the outward movement of the guard roller being limited by stops f
which might be adjustable.
If preferred the guard roller might be mounted and acted upon by springs or
weights so that it would be kept in contact with the upper roller a the goods or
articles being in such a case passed over the guard roller. I have however found
the arrangement illustrated to be more efficient.
For some purposes it might be an advantage to groove the guard roller so as to
cause it to have a "stretching" effect upon fabrics passing below or above it as for
example one half of the length of the roller might be formed with a right hand
screw groove and the other half with a left hand screw groove.
If preferred a grooved or plain non-revolving guide bar might take the place of
the guard roller and be mounted to yield in a similar manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1) The combination of the ordinary rollers a and b with the auxiliary or guard
roller e substantially as and for the purpose set forth and indicated.
2) As applied in connection with mangling wringing calendering or pressing.
rollers a smaller guard roller or bar applied on one side or on each side of the
machine and mounted to have a limited play or movement substantially as and for
the purpose set forth.
