Year: 1880

page_text: LETTERS PATENT to Wilson Riley, of Keighley, in the County of York,
Mechanic, and Samuel Cockshot Taylor, of Morecambe, in the County of
Lancaster, Joiner, for an Invention of "IMPROVEMENTS IN THE METHOD OF
AND APPARATUS FOR OPENING AND SECURING WINDOW SASHES."
PROVISIONAL SPECIFICATION left by the said Wilson Riley and Samuel
Cockshot Taylor at the Office of the Commissioners of Patents on the 29th
January 1880.

MENTS IN THE METHOD OF AND APPARATUS FOR OPENING AND SECURING WINDOW
SASHES."
The object of our Invention is to arrange window sashes in such a manner that
we are enabled to dispense with the use of cords, chains, balance weights, and sash
fasteners, and to prevent the sashes from being opened or closed at the outside of
the building.
We accomplish our object in the following manner:-At each side of the top and
bottom sash next the frame or casing we secure a toothed rack, into which is
geared a screw or worm secured to shafts mounted in suitable journals. The shafts
at each side of the bottom sash are connected together by suitable gearing, and so
arranged that a lever can be placed on one end of the shaft, which when actuated
will cause the worms to revolve and raise or lower the bottom sash, as the case
may be. The top sash is fitted with shafts and worms in a similar manner as the
bottom, and when the lever before mentioned is removed from the shaft ends
neither the top or bottom sash can be raised or lowered.
By our arrangement of regulating window sashes we are enabled to dispense
with the use of all balance weights, cords, chains, pullies, and sash fasteners now
in common use, as the weigh of each sash is carried by the racks and worms at
each side thereof.
By placing suitable guides in connection with the shafts at each side the sashes
are made quite firm, so that the noise caused by the wind shaking the same when
fitted in the ordinary manner is reduced to a minimum.

the said Wilson Riley and Samuel Cockshot Taylor in the Great Seal Patent
Office on the 28th July 1880.
WILSON RILEY, of Keighley, in the County of York, Mechanic, and SAMUEL
COCKSHOT TAYLOR, of Morecambe, in the County of Lancaster, Joiner. " IMPROVE-
MENTS IN THE METHOD OF AND APPARATUS FOR OPENING AND SECURING WINDOW
SASHES."
The object of our Invention is to arrange window sashes in such a manner that
we are enabled to dispense with the use of cords, chains, balance weights, and
sash fasteners, and to prevent the sashes being opened from the outside of the
building.
Such being the objects of our Invention we will now describe the particulars of
the same, aided by the accompanying Drawings, in which Figure 1 represents the
elevation of a window frame and sashes fitted with our apparatus for raising or
lowering the sashes; Figure 2 is an end view of the same; Figure 3 is a section
through the pulley stile shewing an enlarged view of the pinion, worm, and
worm wheel; Figure 4 is an enlarged view of the worm and wheel; and
Figure 5 is a detail shewing our arrangement for placing the rack in bottom sash
in or out of gear with the pinion.
The casing or frame for the sashes is indicated by the letter A; the sashes B
and B' are secured in the casing by ordinary parting and staff beads. When our
apparatus is applied to wide windows we extend a shaft C across the window,
opening as shewn in Figure 1. Near to each end of this shaft we mount pinions D
that gear into racks E, secured at both sides of the top and bottom sashes. On to
the extreme end of this shaft we secure a worm wheel F which is in gear with
worm G, mounted on shaft H and supported by bracket J which is secured to casing.
The shaft H is extended to outside of window casing, and the end of shaft may be
fitted with a handled lever or with a grooved pulley M (as shewn in Figure 4),
around which may be placed a tight cord P, so that by turning the lever or pulling
the cord the worm G will revolve and actuate the other mechanism connected there-
with, raising or lowering the sashes as desired.
For narrow sashes racks fitted to one side of the top and bottom sashes are
sufficient to accomplish our object. When racks are thus fitted the shaft C in
Figure 1 is dispensed with, and worm G, worm wheel F, and pinion D are mounted
as shewn in Figure 3.
Figure 5 shews an arrangement whereby racks in bottom sashes can be put in or
out of gear with the pinions D and the top sash worked independent of bottom
sash. This is accomplished by forming a joint at K near the top of rack in bottom
sash. To this jointed portion of rack we attach a guard L having two notches,
which when either of the notches are placed on to a pin secured to bottom sash
will put the rack into or out of gear with the pinion, as the case may be.
In order to work both top and bottom sashes independently of each other we
apply the apparatus at each side of the window, one of them gearing with the top
sash and the other with the bottom sash, so that by turning the lever or drawing
the cord attached to the apparatus connected with bottom sash the same can be
raised or lowered and the top one remain stationary, and by actuating the
other apparatus the top sash can be raised or lowered and the bottom one remain
stationary.
By the application of racks secured to the sashes and geared with the worm and
worm wheel in the manner described it is impossible to raise or lower the sashes
from the outside of the building.

page_text: what we claim as our invention 18,-
The application of racks E secured to window sashes used in conjunction with
worm G, worm wheel F, and pinion D, substantially in the manner and for the
purposes herein before described.
In witness whereof, we, the said Wilson Riley and Samuel Cockshot Taylor,
have hereunto set our hands and seals, this Twenty seventh day of July,
in the year of our Lord One thousand eight hundred and eighty.
