PROVISIONAL SPECIFICATION.
Improvements in Means for Raising, Lowering, and Securing Sash
Windows in Position.
I, JOSEPH WHITELEY, of Clowes Street, Chapel Street, Salford, in the County
of Lancaster, Pattern Maker, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in means for raising, lowering and
securing sash windows in position and has for its object to simplify the construction
of the said means, to render them more reliable in action and to dispense with cords,
weights and fasteners.
To this end my improvements consist in applying to each of the sash windows a
rack in gear with a worm rotated by suitable means and positioned in the sash
frame.
According to one form of my invention I let into each sash side a rack and
into the respective side of the sash frame I mount in suitable brackets, let into the
sash frame, shafts arranged in a line with and extending from about the middle of
the two sashes to the bottom of the lower sash. The said shafts I preferably
form square in section and at the upper extremities are furnished with the
aforesaid worm wheels respectively one above the other. On one side of the sash
window the lower ends of the said vertical square shafts are furnished with bevel
wheels in gear with other bevel wheels each fixed on a short horizontal shaft,
which latter bevel wheels are in gear with bevel wheels fixed onto two square
cross shafts positioned below the bottom sash in the sash frame, which cross
shafts at the opposite ends are each furnished with a bevel wheel gearing into
bevel wheels fixed onto the lower ends of the aforesaid vertical shafts. The afore-
said short horizontal shafts are formed in such a manner as to receive a crank
handle by means of which and the medium of the said bevel wheels, worm wheels
and racks each of the said sash windows can be raised or lowered independently of
each other and thus opened or closed.
If deemed necessary a coupling device may be employed which when thrown
into gear will permit the raising or lowering of the two sashes simultaneously.
In lieu of bevel wheels, chain wheels or pulleys may be used in connection with
chains or the like.

Improvements in Means for Raising, Lowering, and Securing Sash
Windows in Position.
I, JOSEPH WHITELEY, of Clowes Street, Chapel Street, Salford, in the County
of Lancaster, Pattern Maker, 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 relates to improvements in means for raising, lowering and
securing sash windows in position and has for its object to simplify the construction

page_text: of the said means, to render them more reliable in action and to dispense with
cords, weights and fasteners.
To this end my improvements consist in applying to each window sash racks in
gear with worms rotated by suitable means and positioned in the sash frame.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a sectional elevation.
Fig. 2 a sectional plan at line A-B Fig. 1, and
Fig. 3 a detached side view of my improved means for raising, lowering and
securing sash windows in position.
Fig. 4 is an elevation and Fig. 5 a sectional plan at line C-D of a modification
thereof.
In carrying out my invention according to one form, see Figs. 1, 2, & 3, I let
into each sash side a a rack band in connection therewith I mount in suitable
brackets d, d', let into the 'sash frame c, shafts e, e¹, e³, & e³, arranged vertically in
a line with and extending from about the middle of the said sashes to the bottom
of the lower sash. The said shafts which, I preferably form square in section, are
at their upper extremities furnished with worms f, f', f', f³, respectively, one
above the other. On one side of the sash window the lower ends of the vertical
shafts e, e¹ are furnished with bevel wheels 9, 9', in gear with other bevel wheels h, h²,
'each 'fixed on a short horizontal shaft i, i, which latter bevel wheels are in gear
with bevel wheels k, k', fixed onto two square cross shafts 1, l', positioned below
the bottom sash in the sash frame c, which cross shafts at the opposite ends are
each furnished with another bevel wheel & respectively gearing into bevel
wheels & g fixed onto the lower ends of the vertical shafts e & e. The short
horizontal shafts i & are adapted to receive a crank handle m by means of which
and the medium of the said bevel wheels, worms and racks each of the said sash
windows can be raised or lowered independently of each other and thus opened or
closed or retained in any desired position.
If deemed necessary a coupling device may be employed which when thrown into
gear will permit the raising or lowering of the two sashes simultaneously.
In lieu of bevel wheels, chain wheels or pulleys may be used in connection with
chains or skew wheels or the like as will be readily understood.
Référring to Figs. 4 & 5 the same show the means described adapted for raising,
lowering and holding in any desired position the windows of carriages. In this
case racks b are also let into the sash sides a. The worms fin gear therewith are
each formed with a bevel pinion g in gear with a bevel wheel / having a chain
wheel m, the said wheels and worms being mounted in brackets d fixed into the
sash frame c. A chain or its equivalent m', carried around the sash opening n
by suitably positioned pulleys (not shown), is adapted to engage the chain
wheels m.
The chain m¹ carries a stud o which projects through a slot o' formed in
the side of the carriage, the sliding of which stud imparts motion to the chain m'.
Rotary motion is imparted by the chain m' to the chain wheels m and from the
latter by means of the bevel wheels & g to the worms fin gear with the racks b.
It will thus be seen that by sliding the stud o up or down the window sash a can
be either raised or lowered and be retained in position as may be required.
It will be understood that the invention described may be varied in details such
as the shape and position of the brackets supporting the said vertical and cross
shafts or method of gearing the same up without departing from the nature of my
invention.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is―
"In means for raising, lowering and securing sash windows in position."
1st. The use of recks and wo
the woke bains fived upon the windom soch

substantially as and for the purpose set forth.
2nd. The general construction and combination of parts constituting my improve-
ments operating substantially as and for the purpose set forth.
