PROVISIONAL SPECIFICATION.
Improvements in Window Cleaning Apparatus.
We JAMES EDWARD TRIGG of 4 Saint Phillip Street, Linton Street, Islington
in the County of Middlesex Engineer and ANTHONY JOHN BYRD of 14 St. Mary's
Road, Lower Edmonton also in the County of Middlesex, Decorator do hereby
declare the nature of this invention to be as follows:-
The object of our invention is to provide apparatus which may be operated from
within to clean windows both inside and outside at the same time.
For this purpose we construct a pair of tongs having extensible limbs capable of
being securely fastened at the required length according to the depth of the sash
containing the pane or panes of glass to be cleaned. The extensible limbs are
provided, at their extremities, each with a pillar carrying a pad stock, the two stocks
meeting face to face and exerting a pressure the one upon the other by virtue of the
spring arch of the tongs.
The pad stocks, are covered with suitable interchangeable pads which may be of
textile material or of leather according to the stages or the requirements of the
cleaning operation. These pads are preferably made with a pocket at one end and
a flap at the other end capable of being buttoned or otherwise fastened over the
back of the pad stocks.
To facilitate putting on or removing the pads from the pad stocks we provide a
bar hinged to one of the limbs of the tongs capable of being placed between them
when opened and so maintain the tongs open while the pads are secured upon the
pad stocks.
In applying the tongs to clean windows they are opened to pass the pads beyond
the lower or upper style of the window sash as the case may be and are then allowed
to close their pads in contact with the glass, one inside and the other outside. In
this position the tongs are moved about by holding the limb of the tongs at the inside
while the pads grasping the window pane effect the cleaning operation inside and
outside at the same time.

Improvements in Window Cleaning Apparatus.
We JAMES EDWARD TRIGG of 4 Saint Philip Street, Linton Street, Islington
in the County of Middlesex Engineer and ANTHONY JOHN BYRD of 14 Saint
Mary's Road Lower Edmonton also in the County of Middlesex Decorator, dò
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 :-
The object of our invention is to provide apparatus which may be operated from
within to clean windows both inside and outside at the same time.
For this purpose we provide a pair of tongs shown in the accompanying drawings
in which
Figure 1 is a side elevation of the tongs.
Figure 2 is a front clevation of Figure 1.
The limbs A A B B of the tongs are extensible being provided with sliding
sockets C fixed at the extremities of the limbs A A¹ and stationary sockets D fixed

page_text: at the extremities of the limbs B3 B. The stationary sockets Dare provided with set
screws E easily turned by means of the lever handles fitted thereon so that pressure
may be put upon the plates F to bind the limbs A B and A B₁ respectively to
lengthen or shorten the tongs according to the depth of the sash containing the pane
or panes of glass to be cleaned. At the extremities of the tongs we provide the
pillars G each carrying a pad-stock H, the two pad-stocks meeting, face to face and
exerting a pressure at both sides upon the pane of glass J by virtue of the arched
spring K secured at the base of the tongs by a regulating screw L.
The pad-stocks H are covered with suitable interchangeable pads which may be
of textile material or of leather according to the stages or the requirements of the
cleaning operation. These pads are preferably made with a pocket at one end and
a flap at the other end capable of being buttoned over buttons N or otherwise
fastened over the back of the pad-stocks. The pad-stocks H are loosely attached
to the pillars G so that they may accommodate themselves to bear evenly upon
panes of glass of varying thickness.
To facilitate putting on or removing the pads from the pad-stocks H we provide
a bar M hinged to one of the limbs of the tongs and capable of being placed between
them when opened so as to maintain the tongs open while the pads are secured upon
the pad-stocks.
In applying these tongs to clean windows, they are opened to pass the pads beyond
the lower or upper style of the window sash as the case may be and are then allowed
to close their pads in contact with the glass one inside and the other outside. In this
position the tongs are moved about by holding the limb of the tongs at the inside
while the pads grasping the window pane effect the cleaning operation inside and
outside at the same time.
The pad-stocks H are hollowed at all four sides to make the corners prominent so
as to carry the pads well into the corners of window panes to be cleaned.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1. An instrument for cleaning window panes at both sides simultaneously con-
sisting of a pair of spring tongs carrying pad-stocks at its extremities to urge
suitable pads fitted thereon in contact with window pads substantially as described.
2. In spring tongs for cleaning window panes at both sides simultaneously; the
extensible limbs to make the length of the tongs adjustable to the requirement for
window sashes of various sizes substantially as described.
3. In spring tongs for cleaning window panes at both sides simultaneously; the
means of regulating the tension of the spring arch of the tongs substantially as
described.
