PROVISIONAL SPECIFICATION.
An Improved Device for Locking Sash Frames and Preventing them
from Rattling.
We WILLIAM HYLAND of 2 Dover Street New Swindon in the County of
Wilts Coach Finisher and WILLIAM CLISSOLD of 14 Gooch Street New Swindon
in the County of Wilts Coach Finisher do hereby declare the nature of this inven-
tion to be as follows:-
This our invention relates to an improved device for locking sash frames and
preventing them from rattling and which is particularly applicable to railway
coaches road vehicles and the like but our invention may also be applied to other
kinds of sashes.
Our invention consists in the following parts constructed and arranged as
hereinafter described:
Two base plates of any suitable material and dimensions and having an car or
bracket at either end of each are fixed to the framing within which the sash slides
and to each of the said ears is pivotted a plate having a roller mounted between
them as hereinafter described.
Each of these rollers which may be of rubber, composition, leather, or other
suitable flexible material, is mounted, and is capable of rotation upon a spindle
between the plates before mentioned and the said rollers are capable of exerting
pressure against the frame of the sash to which our invention is applied.
The distance of the sash frame from the centre of rotation of the roller is slightly
less than the radius of the said roller and consequently the sash and the roller
falling by their own weight become jammed and the roller forces the sash against
the framing in which it slides.
By lifting the sash the roller is released and revolves freely, but when the sash
is raised to the required position and released the roller re-locks it as before
described.
The pressure of the rollers upon the sash is sufficient to retain it at any desired
height, but a slight addition to the weight of the sash is sufficient to lower the
same.
All that is necessary therefore to lower the sash, is to give the sash a slight
downward pull; the rollers rotating as the sash is lowered.'
In order to prevent the rollers dropping so that the centres of the rollers are
below the pivots upon which the roller supporting plates are hung we provide the
base plates with lugs through which pass adjusting screws by means of which
screws the rollers may be adjusted and the said accident avoided.
The rollers may if desired be made of hard material such as metal or wood in
which case the parts of the sash frame against which the rollers bear may have a
strip of flexible material preferably of rubber affixed thereto.
If a single roller is employed it would be preferably placed in the centre of the
sash so as to bear against the glass.

An Improved Device for Locking Sash Frames and Preventing them
from Rattling.
We, WILLIAM HYLAND of 2 Dover Street, New Swindon, in the County
of Wilts, Coach Finisher, and WILLIAM CLISSOLD, of 14 Gooch Street, New
Swindon, in the County of Wilts, Coach Finisher, 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 our invention relates to an improved device for locking sash frames and
preventing them from rattling and which is particularly applicable to railway
coaches, road vehicles and the like, but our invention may also be applied to other
kinds of sashes.
Our invention consists of the following parts constructed and arranged as herein-
after described and illustrated in the accompanying drawings, in which-
Figure 1 shows our improved device in cross section taken on the line xx in
Figure 2.
Figure 2 is a front view of the same looking in the direction of the arrow y in
Figure 1.
In carrying our invention into practice, we fix upon each side of the sash
framing our improved device which is constructed as follows-
A base plate A of any suitable material and dimensions and having an ear or
bracket a at either end thereof fixed to the framing within which the sash slides,
and to each of the said ears is pivotted at a plate B having a roller C mounted
between them as hereinafter described.
The said roller C which may be of rubber, composition, leather or other suitable
flexible material, is mounted and is capable of rotation upon a spindle c between the
plates B before mentioned and the said roller is adapted to press against the frame
of the sash to which our invention is applied.
One of the devices is preferably applied at each side of the framing the rollers C
of each engaging the styles of the frame of the sash, as illustrated by the line D,
Figure 1.
The base plates A are preferably sunk into the framing of the door in the
desired position and the pressure of the rollers C upon the frame may be regulated
as required by the adjusting screws u¹.
The distance of the sash frame D from the centre of the pivot b is slightly less
than the distance from the pivot to the periphery of the roller C and consequently
the sash D and the roller C falling by their own weight become jammed and the
roller forces the sash against the framing in which it slides.
By lifting the sash the roller is released and revolves but when the sash is raised
to the required position and released the roller re-locks it as before described.
We provide a friction roller of wood, metal or other material E mounted between
the plates B which will prevent the rotation of the roller from the weight of the
supported sash.
The pressure of the rollers upon the sash is enough to retain it at any desired
height, but a slight addition to the weight of the sash is sufficient to lower the
same. All that is necessary therefore to lower the sash is to give the sash a
slight downward pull; the rollers rotating as the sash is lowered.
In order to prevent the rollers dropping so that the centres of the rollers are
below the pivots upon which the roller supporting plates are hung, we provide the
base plates with lugs F by means of which the said accident is avoided.
The rollers may, if desired, be made of hard material such as metal or wood, in
which case the parts of the sash frame against which the rollers bear may have a
strip of flexible material, preferably of rubber, affixed thereto.
If a single device is employed it would be preferably placed in the centre of the
sash, so that the roller thereof would bear against the glass of the sash.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
:
An improved device for retaining sashes consisting of an adjustable base plate
having ears thereon and screws for the adjustment of the said base plate, in
combination with a roller supported in brackets pivotted between said ears and a
friction roller adapted to bear against the said roller the whole constructed,
arranged and operating substantially as described and illustrated.
