PROVISIONAL SPECIFICATION.
An Improvement in Carriage Doors and Windows.
I WILLIAM KNEEN of 66 Scott Street Barrow-in-Furness Lancashire do hereby
declare the nature of this invention to be as follows:-
A method of balancing carriage windows without increasing their bulk. A thin
weight fixed in a horizontal position and guided by two rods of metal which are let
into the weight and project one sixteenth of an inch or thereabouts beyond the face,
of the weight, nearest the window. The weight and window are thus enabled to.
pass each other in their up and down movements without colliding and yet not more
that one sixteenth of an inch or thereabouts of space exists between them.
By means of my invention the window of an ordinary Cab or Railway Carriage
instead of being raised and lowered by a strap is counterbalanced by a weight in a
horizontal position containing two groves. Two rods of iron or other metal secured
both at their upper and lower ends to the door are let into the groves before-mentioned
for the purpose of guiding the weight in its up and down movements and preventing
it colliding with the window frame on the one side and the brackets to which the cords
or chains are fastened on the other side.
What I claim to be original and my own invention is the method of hanging
carriage windows or other frames requiring balance weights without loosing space
between the window frame and the weight and without increasing the bulk of the
door.

An Improvement in Carriage Doors and Windows.
I WILLIAM KNEEN of 66 Scott Street Barrow in Furness in the County of Lancaster
Builder 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 :-
My Invention has for its object to balance the windows without increasing the bulk
of the door with which they are used. I employ a flat and thin weight inside the
panel of the door and guided by rods situated towards the middle portion of the
door so that the weight does not extend all across the space inside the panels but
leaves space at the sides for the descent of the brackets or the like affixed to the
window. The rods so guide the weight that it does not collide with the window
nor does it sway laterally. The weight is connected to the window by cords or chains
passing over pulleys inside the panel.
The accompanying drawing shews what I consider the best mode of constructing a
carriage door and window in accordance with my Invention Figure 1 is a side view
with the panel removed. Figure 2 is a vertical transverse section on the line 1, 2,
and Figure 3 is a horizontal section on line 3, 4. In figures 1 and 2 the full lines
shew the position when the window is closed and the dot and pick lines shew the
position when the window is open.
The window. A slides in grooves in the posts B of the door, and to brackets a
secured to the said window are attached the ends of chains or ends C,, which pass over
pulleys D carried by the panel and the other ends of the said Cords are attached to
the weight E which is guided by rods G affixed to the door inside the panels. To
economize space to the utmost I prefer to make the holes or recesses in the weight for
the rods G to enter, in the form of grooves at the side so that the weight does not
project beyond the rods, which rods therefore can act as a guide to the window with-
out danger of its fouling the weight. Moreover owing to the weight not extending
all across the whole of the space in the panel and being guided by the rods situated
as shewn, the brackets or the like a cannot collide with the weight. The counter-
balance weight retains the window in the position to which it is brought, and if it be
required to fix the window more securely in this position there may be a fastening
provided for the purpose such for example as the eccentric piece H rotated by the
thumb piece h to wedge against the window and so retain it.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is
In carriage windows and doors a weight for counterbalancing the window the said
weight being connected to the window and arranged to slide upon rods in between
the panels or in the space in the door below the window all substantially as and for
the purpose herein before described.
