PROVISIONAL SPECIFICATION.
Improvements in Devices or Means for Retaining Windows or Doors
in Any Desired Position.
We, JAMES WADDINGTON of 22, Warwick Street, Barrow-in-Furness in the
County of Lancaster, Commercial Traveller, and JAMES PENDLEBURY of
18, Lowwood Road, Birkenhead in the County of Chester Engineer, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide a ready and easy means for retaining
windows or doors in any suitable position to which they may have been put. For
this purpose we adapt to the outer edges of the two side pieces of the window
frame or door, springs, preferably two on each side.
In order to allow the window or door to be moved easily, we fix on the ends of
these springs small rollers which are pressed by the springs against the sashes or
frames as the case may be and by revolving as the window or door moves thereby
greatly reduce the friction and augment the ease of moving the same.
As will be seen this system can readily be applied to any window or door and
will be found specially convenient as a medium for doing away with the strap and
catches employed in railway carriage windows.
Grooves, milled edges, or roughened surfaces on the roller or opposed surface
may be suitably employed in this arrangement to secure better working.

COMPLETE SPECIFICATION.
Improvements in Devices or Means for Retaining Windows or Doors
in Any Desired Position. .
We, JAMES WADDINGTON of 22 Warwick Street, Barrow-in-Furness in the
County of Lancaster, Commercial Traveller, and JAMES PENDLEBURY of
18 Lowwood Road, Birkenhead in the County of Chester, Engineer, 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:
The object of this invention is to provide a ready and easy means for retaining
windows or doors in any suitable position to which they may have been put.
It is best described by aid of the accompanying drawings, in which :-
Figure 1 is an elevation of part of a door and a window with the invention
applied, the frame being partially broken away to show it.
Figure 2 is a vertical section of same.
Figure 3, a slightly perspective view of the, window sash with invention
attached.
In these-

D springs screwed to the window sash and carrying rollers E in their coiled-up.
slotted ends. These rollers are pressed by the springs against the framework of
the door, and by revolving as the sash moves thereby greatly reduce the friction
and augment the ease of moving the same. In the framework at top we prefer to
make a shallow groove H for the roller to fall into. We may also do this at
points lower down. By this means, even if the springs are too weak to afford

page_text: enough friction to hold up the sash by pressure alone, it will be held at such
heights as the roller will fall into these grooves and yet a little additional force
will cause it to rise or fall sufficiently to withdraw the roller from the groove.
G is a handle for raising or lowering the window. It is not absolutely necessary
to fit rollers to the springs, the springs can be turned round so as to resemble
rollers or have a rounded contour, and thus form a suitable equivalent for the
rollers.
It is obvious that the form of spring is comparatively immaterial, so long as it
is sufficiently rigid not to be broken or drawn out of position longitudinally with
the travel of the sash and yet sufficiently elastic to be pressed back the requisite
degree with the movement of the sash, yet always be pressing against the frame-
work of the latter. The handle can also be varied in design and so can the
framework.
As will be seen, this system can readily be applied to any window or door and
will be found specially convenient as a medium for doing away with the strap and
catches employed in railway carriage windows. Grooves, milled edges or
roughened surfaces on the roller and (or) opposed surfaces may be suitably
employed in this arrangement, whereby any slipping of the rollers is avoided and
better working is secured.
Having now particularly described and ascertained the nature of our said inveu-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination of the springs, with rollers or their equivalent, with the
window sash and door frame and a device such as a handle for obtaining a purchase
on the sash, substantially as described.
2. In combination with the matter substantially set forth in Claim 1, the
grooves H for the purposes set forth.
3. Forming the rollers and (or) their opposed surfaces with grooves, milled
edges or roughened surfaces substantially as and for the purpose described.
