PROVISIONAL SPECIFICATION.
Improved Means or Apparatus for Raising, Lowering, and Sustaining
in Position Railway Carriage and other Window Sashes.
I, JOHN SIMPSON of Quadrant Chambers, Buxton, in the County of Derby:
Architect, &c. do hereby declare the nature of this invention to be as follows:-
This Invention has for its object, simplicity of mechanism, cheapness, and the
impossibility of interference and consequent injary, by the general public; yet
allowing adjustment or renewal in the simplest and cheapest manner.
The strap used almost invariably for raising and lowering railway & other carriage
window sashes, which is far from satisfactory in its working, expensive & liable to
injury, is entirely done away with, as are also its accessories, and the wide open space
between the garnish bar and outer middle rail at present rendered necessary by the
use of strap.
I propose to run the sash in a straight groove at one or both sides of door I place.
a loose friction bar, hinged or pivotted at or near the middle of side of door. To
the bottom end of this friction bar I attach a spring which holding the friction bar
at an angle with side of door, keeps the sash in any position desired. For the
purpose of adjusting the power of spring, I place at the opposite side of door a
hed screw, which working into a female screw, attached to spring, tightens or relaxs
the spring as required. The head of bed screw is the only part of mechanism
visible.
To facilitate the working of sash, and to prevent binding; I place if necessary a
small wheel or pulley, at or near the bottom corners at both sides of sash, the one
working on friction bar being if necessary cogged.

JOHN SIMPSON Quadrant Chambers Buxton, Derby 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 :-
This invention has for its object, simplicity of mechanism, cheapness, and the
impossibility of interference and consequent injury by the general public; yet
allowing adjustment or renewal in the simplest and cheapest manner.
The strap used almost invariably for raising and lowering railway and other
carriage window sashes, which is far from satisfactory in its working, expensive and
liable to injury; is entirely done away with, as are also its accessories, and the inside
open space, between garnish bar and other outer middle rail at present rendered
necessary by the use of strap.
:
I propose to control the sash by means of a loose friction bar, hinged or pivotted
at or near the middle of side of door, and kept at an angle with the side, by means of a
spring my arrangement being entirely out of sight, does not admit of any
interference by the general public, but in the event of spring being too slack, or
two strong I place at foot of door a bed screw working into a female screw attached
to spring which allows the spring to be adjusted to any required strength. The sash
in this arrangement being close to garnish bar necessarily contracts to a minimum
what is usually a wide open space.

Referring to the Drawing
Fig. 1 is an elevation of a Railway Carriage door looking from the inside.
Fig. 2 is a section of same.
In these A is the loose friction bar pivotted at F. B is the spring which controls
and actuates friction bar-and it is here shown as a coiled spring, it is attached to
bottom of friction bar and to a female screw D. C is the head of bed screw that
works in female screw D and thus forins adjustment for spring. E is block for
window to rest on. G is small wheel or pulley to facilitate action of sash and to
prevent binding. H is sash 1 is bottom of inside of door, to be screwed. The
friction bar A may be toothed and the small wheel work into it to facilitate movement
of sash. The sash simply requires to be pressed down or lifted .up by a stud placed on
top rail of sash, and the friction bar being controlled by spring binds and so keeps
it in any position desired. The spring may be renewed as often as desired, in a very
simple manner. The bottom board I must be arranged as shewn on section and screw.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1. The application of a friction bar at one or both sides of door hinged or pivotted
near the centre and controlled by and actuated by a spring, thereby binding the sash
so as to sustain it in any desired position.
2. In a combined arrangement for raising and sustaining in position Railway
carriage and other Sashes for windows the friction bar A, the spring B controlled by
screw D. Block E with friction. wheel or pulley G to facilitate sliding of sash H,
substantially as described and for the purpose set forth.
