A New and Improved Top and Cover for Commodes and Bedpans
and such like Utensils, and for other Suitable Purposes.
1, FREDERICK TYERMAN, of No. 119 Algernon Road, in the Parish of St. Mary,
Lewisham, in the County of Kent, Architect and Surveyor, do hereby declare the
nature of this invention to be as follows:-
This Invention bas for its object improvements in the tops and covers of Commodes
and Bedpans, and such like Utensils, whereby the Pan, which is to be used in the
ordinary way, is closed and sealed by a sliding, rolling or other Screen before the
user removes from position. To carry out this object I prefer a moveable frame,
having an open space in the centre, and prepared of the required size, strength and
shape, of wood, metal or other suitable material, to fit over and cover an ordinary or
other approved Commodo or Bedpan or other similar Utensil, and so made and
packed on its under side with lining or seating as to fit securely and tightly by
grooves and clips or other approved means on to the top or upper part of the Pan.
The underneath part of this frame is prepared on three of its inner sides, next
the opening in the centre, with grooves packed with india-rubber or other suitable
material, into which grooves the bound or otherwise prepared edges of the part
hereinafter called the screen or Sliding Cover are to run and work.
On the other or fourth side of the frame an airtight case of similar material to the
other part of the frame, is framed, enclosed in which is a spring or other approved
roller, around which the screen or sliding cover hereinafter described, is rolled, and
from which it is to run and work.
The Screen or sliding cover before alluded to, is composed of wood, metal or any
approved and suitable material, but by preference of Asbestos cloth, or material of a
similar impervious character, strengthened and strained as may be necessary by light
metal ribbon or other stretchers and the edges so bound and prepared as to fit securely
and effectually into the packed or otherwise prepared grooves on the three sides of the
frame before mentioned and described.

page_text: This Screen or sliding cover is to be available during the use of the Pan, that is,
immediately before the user rises from the seat, and is to be drawn forward and out
of its case by cords or chains and runners formed on two sides of the frame, or by any
other approved means, and when at its full extent and properly home in the groove on
the opposite side to the roller, it is secured in its place by a spring catch and slot, 5
and. the cords or chains so run out, secured for convenience on the outer side or edge
.of the frame by a hook or catch.
When this has been done, the excretion is thoroughly confined, covered and sealed
in an air-tight pan, all foul gases and unhealthy effluvia prevented from escaping
into the apartment, and the risk of soiling the linen, (a matter of serious import to 1
an infirm patient,) entirely avoided.
One or more valvular openings to be formed in the Screen or sliding cover, for
the purpose, when in use or run out from the roller, of permitting liquid or powder
disinfectant to be ejected into the interior of the pan.
After use, the top, sliding cover and pan, in their entirety, are to be taken from 1
the Commode or Bed, the disinfectant ejected, and the whole carried from the
. apartment in the usual way.
When the pan has to be cleansed, the top complete is to be removed, the screen
or sliding cover is then released and returns to its roller case. The whole Apparatus
is again ready for re-use on being replaced and secured on the pan.
This Invention is also adapted for the tops of various articles requiring lids or
covers.

1, FREDERICK TYERMAN, of No. 119 Algernon Road, in the parish of St. Mary,
Lewisham, in the County of Kent, Architect and Surveyor, do hereby declare the
nature of this invention and in what manner the same is to he performed, to be
particularly described and ascertained in and by the following statement, reference
being made to the accompanying drawings
This Invention has for its object improvements in the tops and covers of commode
and bed pans and such like utensils, whereby the pan, which is to be used in the
ordinary way, is closed and sealed by a sliding, rolling or other screen cover, before
the user removes from position.
To carry out this object I prefer a moveable frame, having an open space in the
centre, and prepared of the required size strength and shape, of wood, metal, or other
suitable material, to fit over and cover an ordinary or other approved commode or bed
pan, or other suitable utensil, and so made and packed on its under side with lining
or seating as to fit securely and tightly by grooves and clips or other approved means
on to the top or upper part of the pan.
The underneath part of this frame is prepared on three of its inner sidos next the
opening in the centre, with grooves packed with Woodite, india rubber, or other
suitable material, into which grooves the bound or otherwise prepared edges of the
part hereinafter called the Screen or sliding cover are to run and work.
On the other or fourth side of the frame an airtight case of similar material to
the other part of the frame, is formed, enclosed in which is a spring or other approved
roller around which the screen or sliding cover hereinafter described, is rolled, and
from which it is to run and work.
The Screen or sliding cover before alluded to is composed of wood, metal or any
approved suitable material, but by preference of Hospital sheeting, Woodite, asbestos
cloth, or material of a similar impervious character, strengthened and strained as may
be necessary by light metal ribbon or other stretchers, and the edges so bound and
prepared as to fit securely and effectually into the packed or otherwise prepared
grooves on the sides of the frame before mentioned and described.
The Screen or sliding cover is to be available during the use of the pan,
immediately before the patient or user removes from the seat, and is to be drawn
forward and out of its case by cords or chains and runners formed on two sides of the
frame or by any other approved means, and when at its full extent and properly home
in the groove on the opposite side to the roller, it is secured in its place by a spring
catch and slot, and the cords or chains so run out secured for convenience on the
outer side or edge of the frame by a hook or catch.
In the Drawings hereunto attached Fig. I. is a plan of the new or improved top
and cover. Fig. II. is a transverse section on line P Q. Fig. III. is a longitudinal

K. valvular opening. L. packing between top and pan. M. clips. R. upper part

When the rolling or sliding screen cover has been run out as before described, the
contents of the pan or utensil are throughly confined, covered and sealed therein, all
foul gases and unhealthy effluvia prevented from escaping into the apartment and the
risk of soiling the linen, a matter of serious import to an infirm patient, entirely
avoided.
One or more valvular openings are formed in the screen or sliding cover, for the
purpose, when in use or run out from the roller, of permitting liquid or powder
disinfectant to be ejected into the interior of the utonsil.
After use, the top, sliding cover, pan or utensil, in their entirety, are to be taken
from the commode or bed, the disinfectant ejected, and the whole carried from the
apartment in the usual way.
When the pan has to be cleansed, the top complete is to be removed, the screen or
sliding cover released and returned to its roller case, and the whole apparatus is again
ready for reuse on being replaced and secured on the pan.
This Invention is also adapted for the tops of various articles requiring lids or covers,
whereby the contents can be enclosed and preserved.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declaro that what I
claim is,
1. A new or improved top with rolling or sliding screen cover, running in grooves;
for commode and bed pans, and such like utensils, and for other suitable purposes.
2. A new or improved top to commode and bed pans and such like utensils, whereby
the contents can be instantaneously and herinetically enclosed therein without the
patient or user rising from the seat.
3. A new or improved top to jars and other suitable articles requiring or having
covers, whereby the contents can be hermetically enclosed and preserved therein.
4. The general arrangement and combination of the parts, for the purposes set
forth, and substantially as described herein and illustrated by the annexed drawings.
