MEANS FOR HOLDING UP CARRIAGE AND OTHER WINDOWS"
"
IMPROVED
This invention relates to the means for holding up windows whereby sash lines.
and pulleys are dispensed with in the case of Windows in Buildings.
In order to effect the above I suitably fix at one side of the window a roller or
rollers kept in forced contact with the window by a spring or springs acting either
directly or indirectly on the said roller or rollers the said spring or springs being
sufficiently strong so as to press the opposite side of the window against the surface
in which it is fitted so that when the window is pushed up it will be held in position
by the friction on the one side at the same time it can be pushed up or pulled down
easily on account of the roller or rollers on the opposite side

"IMPROVED
This invention relates to means for holding up windows whereby sash lines and
pulleys are dispensed with in the case of Windows in buildings.
In order to effect the above I suitably fix at one side of the window a roller or
rollers kept in forced contact with the window by a spring or springs acting either
directly or indirectly on the said roller or rollers the said spring or springs being
sufficiently strong so as to press the opposite side of the window against the surface
in which it is fitted so that when the window is pushed up it will be held in position
by the friction on the one side at the same time it can be pushed up or pulled down
easily on account of the roller or rollers on the opposite side
And in order to explain my said invention more fully I will now proceed to
describe the same with reference to the accompanying sheet of drawing on which
the same letters are used to denote the same parts
Figs 1. 2, and 3 shew 3 ways of adapting my invention to windows in buildings
Figs 4. 5. & 6 shew sections through lines X X Figs 1. 2 and 3
Figs 7. 8, 9, 10, 11, and 12, shew details hereinafter referred to
In fig 1 my apparatus (shewn drawn to an enlarged scale at Figs 7 7ª and 8) is
fitted in the sash frame a and in figure 2 it is fitted in the sash b. The apparatus
referred to consists of a box c in which is fitted a spring d on which rests piece e
carrying roller f. The box c is fastened either in the sash or sash frame at one side
thereof as represented at figs 1 and 2. At fig 3 the apparatus is also fixed in the
sash but in such position that the roller may come in contact with the centre
bead g of the sash frame a and in this case my apparatus is fitted on each side of
the sash as shewn in this figure. This latter arrangement is more particularly
adapted for heavy windows. In the drawing the windows are shewn partly open.
The action is as follows upon the sash being pushed either up or down the rolling
surface on the one side of the window will enable such window to be raised or
lowered easily whilst the friction of the sash on the opposite side (on account of
the pressure of the spring d) against the sash frame will have the effect of holding
the window at any desired height without the use of sash lines weights and pulleys.
In figure 3 the action is precisely the same the friction being caused by the contact
of the sash with the outside beadings the rollers rolling on the centre beading as
above described
Although I have described and shewn my invention as applied to windows for
buildings it is obvious that the same may be applied to carriage windows and for
this purpose the method shewn at fig 1 would be applicable. Fig 7" shews the
apparatus as made to suit fig 3 Having thus described the nature and object of
my said invention and the means whereby the same may be carried into practical
effect I would remark in conclusion that I do not intend to limit myself to the

page_text: precise details herein described but what I claim as my invention and desire to
secure by the hereinbefore in part recited Letters Patent is
The means for holding up windows substantially as described and shewn
