Improvements in and relating to Coverings for Closet Seats.
We, GEORGE LAWRENCE of 130 Latimer Road, Notting Hill, Engineer, and
ARTHUR COWPER RANYARD of 11 Stone Buildings, Lincoln's Inn, Barrister, both in
the County of Middlesex, do hereby declare the nature of this invention and in
what manner the same is to be performed to bo particularly described and ascertained
in and by the following statement :—
This invention relates to closet seats and consists principally in an improved
covering arranged over the said seat with mechanism for moving the said covering so
that each user may obtain a clean and unused surface over the said seat. A further
improvement consists in constructing the said mechanism so that the covering shall
be locked in place and only movable when the mechanism shall have been temporarily
unlocked for a limited movement of the covering by placing a penny or other coin in
a slot for reception thereof.
The covering consists of a band of paper or linen or other suitable fabric of
indefinite length and of breadth sufficient to cover the closet seat or sufficient part
thereof and pierced at intervals with holes of a suitable size somewhat smaller than
that in the closet seat, the said holes so spaced along the band that when they are
brought in successive agreement with the orifice over the pan in the seat that part of
the surface of the band which was formerly exposed on the seat is replaced by an
unused part of the band.
In the accompanying drawings, Figs. 1 and 2 are vertical cross sections at right
angles through the closet seat showing the covering and parts connected therewith.
Fig. 3 is a plan view partly in section on line ab" Fig. 1. A is the covering band
wound upon rollers and stretched over the seat preferably from back to front as
shown. At the back of the seat B a part is partitioned off to receive the
roiler D on which the unused band is wound. The band A passing through a
slot E along the bottom of the partition of the compartiment C extends forward
over the seat B and passing down through a slot F in the riser G is fastened on
the roller H on which it is wound after use.
The shaft of the roller H is provided with the bevelled wheel J gearing with the
bevelled wheel K on the vertical shaft I, which extends upward through the seat and
terminates in the knob or handle M by which it may be revolved.
When the covering is to be movable only after the necessary coin has been
inserted into the machine and then only for a length sufficient to replace the
previously exposed portion on the seat by an unused portion the following mechanism
is added to that above described.
The rollers D and H are parallel to each other and are provided with recesses
or teeth so that they may be locked against revolution in either direction by
pawls D'and H' respectively these pawls being so pivoted that their weight causes
them to fall into and engage in the said recesses. The lever N is pivoted at N'
one arm extending to the pawl D' and having a pin N adapted to raise the said
pawl D' when the lever is moved, the other end extending towards the pawl H¹
and terminating on u level with the tail of the said pawl. O is the rod of the
plug handle and on this rod or an equivalent rod slides the weight O' which when
it has fallen into its lowest position rests upon and depresses the tail of the pawl F'
and the arm of the lever N opposite to the said pawl so that the rollers D and H
are simultaneously unlocked. The weight O' is lifted when the plug handle_rod
is raised and is maintained in its raised position by the two swinging rods P P
pivoted at P and connected to rods QQ pivoted at the ends of the coin slot so
that when the coin is inserted it presses apart the said two rods Q Q spreading

page_text: the rods P P and allowing the weight to fall. The rods P P fall together by
their own weight the weight O' is tapered so as to press them apart when
lifted.
The coin R having passed between the rods QQ falls into the chute R¹ and
thus through the slot R in the disc R on the rud L. The coin thus falls between!
the plates SS fixed to the plate R³ and the lower plate R₁ and the edge of the
coin projects from between these plates, by turning the rod I the edge of the coin
arrives against the inclined plane S' on the spring-pawl S² and so presses outward
the said spring-pawl so that the nose S³ thereof leaves the recess S in the edge
of the plate R and allows a full revolution to the rod L sufficient to replace the
exposed portion of the covering with another unused portion. The coin having
fallen out by its own weight after deflecting the pawl S³ at any desired part of
the revolution as from Sto S' into the tray S the pawl will drop back into the
recess Safter the revolution of the disc R³ is completed and the latter will be
again locked.
The rollers D and H may ta split and the parts secured together by ferrules
or otherwise leaving a slit for the hand of paper to pass through freely so as to
pormit of an automatic adjustment of the band square to the roller as it winds.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to he performed we declare that what we
claim is :-
1. A closet seat covering consisting of a band of paper, linen or other suitable
fabric of indefinite length provided with holes spaced along its length substantially
as set forth.
2. The combination with a closet seat of a band covering delivered from one
roller and gathered on another substantially as illustrated and described.
3. The combination with rollers D and H of pawls for locking the same and a
movable weight adapted to release the said pawls simultaneously substantially as
set forth.
4. The method of raising the said weight by means of the plug handle rod sub-
stantially as set forth.
5. The method of sustaining the said weight by swinging supporting rois and
of releasing the same by putting in a coin substantially as and for the purpose set
forth.
6. The combination of the disc R³ having the recess S₁ with the pawl S* adapted
to be deflected by the coin substantially as and for the purpose set forth.
