PROVISIONAL SPECIFICATION.
An Improved Construction of Cover or Grating for Covering
Openings or Receptacles, and in the Means Employed for
Operating the said Grating or Cover.
I, WILLIAM IVES, of Waterhouse Street; Halifax, in the County of York,
Architect, do hereby declare the nature of this invention to be as follows:-
In constructing my improved grating which may be used for covering openings
or receptacles in any position or in covering spittoons, when used for spittoons
I insert into the floor of a railway carriage or other vehicle, a suitable form and
size of dish to be covered by one or more sliding lids. The lid is preferably
divided into two parts connected together on the underside by cords, tapes, chains
or other suitable device, whilst one or both of the said lids has connected to it one
or more cords tapes or chains, the opposite ends of which are connected to weights,
the arrangement being such that when one of the lids is slided, say by the foot of
a person or by other means, the movement of one lid operates the adjoining lid in
the opposite direction but as soon as pressure is taken off the opening lid the
weights draw the said lids together and so cover up the opening. Instead of
employing two lids only one may be used.
Instead of using weighted cords or chains as just described for closing the lids,
I may employ an arrangement of rack and wheels together with one or more
springs.

COMPLETE SPECIFICATION.
An Improved Construction of Cover or Grating for Covering
Openings or Receptacles, and in the Means Employed for
Operating the said Grating or Cover.
I, WILLIAM IVES, of Waterhouse Street, Halifax, in the County. of York,
Architect, 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 :-
'
In constructing my improved cover or grating which may be used for covering
openings or receptacles in any position, also for covering spittoons and if for the
latter I insert into the floor of a railway carriage or other vehicle, a suitable form
and size of dish to be covered by one or more sliding lids.
The lid is preferably divided into two parts, connected together on the underside
by racks and pinions or by cords tapes or chains as fully described in a prior Patent
granted to me No. 15,599.
In order that my present invention may be more fully understood I will make
reference to the accompanying sheets of drawings, wherein Fig. 1 is a plan view of
my improved grating or cover partly in section for the sake of clearness; Fig. 2
longitudinal section through line a- of Fig. 1, and Fig. 3 cross section.
A represents the floor of a railway carriage or other place into which I insert my
improved cover. J represents an opening of any suitable size and shape formed in
the floor or other place to be covered by my improved lid or lids hereinafter more
P 37

page_text: fully described. B and B¹ are rectangular or other shaped plates, let into the
floor and having a central opening D of any shape over the opening J. The
plates B and B shewn in Fig. 1 in two pieces may be made in one piece as shewn
in Fig. 4. Underneath these lids B and B¹ are sliding plates or covers C and C¹
with rabitted edges E or otherwise so as to ensure a complete covering up of
the receptacle or spittoon or opening J. The sliding plates C and C' are each
provided with arms C" having racked teeth F in gear with a pinion wheel G
which racks and pinions may be arranged on one or both sides of the apparatus
so that when one of the lugs H rising up from each of the plates C and C¹ is
moved by the foot, umbrella or walking stick (of the person desiring to use the
spittoon) in the direction of one of the arrows, the pinion wheel or wheels G will
cause the other plate to slide in the opposite direction thereby opening direct
communication between opening D and the opening J underne.ch which is now
ready for use, but as soon as the pressure of the person's foot or walking stick is
removed from either of the said lugs H the said sliding plate C and C¹ would
be operated in the opposite direction by a cord and weight not shewn (but
which may be at either one or both ends of the apparatus) passi g over pulley K
and K', thus covering up the orifice J. It will be understood hat these pulleys
and weights may be placed in any other suitable position to .nswer the same
purpose of closing.
Instead however of using a weighted cord to actuate the plates C and C¹ spiral
springs as set forth in my prior Patent No. 15,599" may be employed in conjunction
with these racks and pinions.
Instead of using racks and pinions for moving the sliding ids C and C¹ in
conjunction with a weighted cord I may use cords or tapes L 1 ssing over guide
pulleys M as shewn in Figs. 4 and 5 in the accompanying draw ags. I also wish
it to be understood that in lieu of one cord only on each side as here shewn there
may be two on each side as shewn in previous Patent No. 15,599**.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I dec re that what I
claim is :-
}
Firstly. The construction of a cover or grating for spittoons or other receptacles
consisting of two sliding lids operated simultaneously by racks nd pinion wheels
and a weighted cord as shewn in the drawings and described in tl Specification.
Secondly. The construction of a cover or grating for sittoons or other
receptacles consisting of two sliding lids operated simultaneou ly by racks and
pinion wheels and one or more spiral springs as herein described.
Thirdly. The construction of a cover or grating for spittoons or other
receptacles consisting of two sliding lids operated simultaneously by cords or tapes
in combination with a weighted cord as shewn in the drawings and described in the
Specification.
