Improvements in Appliances for Facilitating the Opening, Closing,
and Securing Window-sashes of Houses and other Buildings.
T, WILLIAM SAMUEL LAYCOCK, of Rammoor, Sheffield, in the County of York,
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention has for its object to greatly facilitate the opening and closing of
window sashes, and to permit of the window being left sufficiently open for
ventilation, with security.
It consists of an apparatus part of which is fixed to the top edge of the bottom
sash and part of the bottom of the top or outside sash.
In carrying out my invention according to one arrangement, I make the part that
is fixed upon the top or outside sash, to consist of a plate by which it is secured to the
sash and a vertical rack of any desired length, say for example six inches. The
portion that is fixed upon the top edge of the lower or inside sash, consists of a pinion
constructed to engage with the before mentioned rack and which can be turned by a
suitable handle inside the room. A pawl or catch engages with the teeth of the pinion.
aid prevents it being turned in the direction to lower the sash and so open, the
window except when raised out of gear. The pinion with its axle, and the catch
are enclosed in a convenient casing, which is prépared to be readily secured to the
sash.
.
The catch can be operated by a projecting knob outside the casing.
Although I have described the use of a rack and pinion, I may use a screw instead
of a rack, in which case the screw would be secured to the top or outside sash, as
before described with respect to the rack, and would pass through the threaded boss of
a small bevil wheel which would be caused to revolve by a similar bevil wheel geared
into it and turned, by a handle in the former manner. In this arrangement a
pawl or catch would not be required..
Instead of the pair of bevil wheels above described Imay substitute a worm wheel
and worm, or a combination of such wheels.
The Sash may thus be opened by means of the apparatus to any distance within its
range of action, and if for any purpose (such as cleaning) it is desired to open
the sashes to a greater width, the action of the apparatus is simply continued until the
parts are disconnected when the sashes can be opened in the usual manner.

1. WILLIAM SAMUEL LAYCOCK, of Ranmoor, Sheffield, in the County of York.
Manufacturer, 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 has for its object to greatly facilitate the opening and closing of
window sashes. and to permit of the window being left sufficiently open for ventilation.
with security. It consists of an apparatus, one part of which is fixed to the top edge
of the bottom sash, and the other part is fixed upon the bottom of the upper sash or
window frame.

page_text: The annexed sheet of drawings clearly illustrates an apparatus made according to
my invention.
Fig. 1, is a side elevation of apparatus.
Fig. 2. is a front view of same.
In carrying out my invention according to the arrangement shown in the
illustration, I make a vertical rack A, of any length to suit various requirements, and
of any desired cross sectional configuration, such as round for example; it is secured
to a foot plate B, and may have teeth of fine or coarse pitch, and this part is secured
or otherwise fastened upon the bottom part of the frame of the upper sash.
The other part of the apparatus consists of a framework C, having a foot plate D, hy
which it is secured tothetop edge of the lower sash, and it is also providedwith a tubular
cover E. to receive and protect the rack A, and to bold the said rack so that its teeth
will engage and be kept in gear with the corresponding teeth of a pinion F.
The pinion F is carried by side plates G. part of the one seen in Fig. 1, being
broken away to enable the pinion to be clearly seen. The said pinion is made to
revolve by means of a worm H, upon a shaft or axle 1, which is readily turned by a
handle J. indicated by dotted lines, and is supported in the bearing K.
When therefore the handle J is turned, the rack A is raised or lowered as the case
may be, and with it the upper sash, to any required extent; the construction of the
mechanism prevents any movement of the rack except by turning the handle J,
therefore although the sash with the rack may be lowered and left open sufficient for
the purpose of ventilation, it cannot be opened any further except from the inside by
the legitimate means.
For cleaning and other purposes the rack may be run out and disengaged from the
pinion F.
Although I have described the above arrangement as being the one that I prefer. I
may use a screw in place of a rack, the said screw passing through and working in a
screw threaded bevil wheel, driven by a second bevil wheel and its axle or shaft from
the inside of the room; or as an alternative 1 may use a rack with an ordinary
pinion and turn it by means of a handle at the side, but in this case a catch to engage
with the pinion and prevent it being turned until the catch was withdrawn would be
required.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is be performed, I declare that what I
claim is
1. The appliance for opening, closing, and securing window sashes, substantially as
herein before described, and as illuustrated in the Figures 1 & 2 of the drawings.
2. An appliance for opening, closing, and securing window sashes, consisting of a
vertical rack, (or its equivalent a screw) to be attached to the top sash, and a suitable
frame to be attached to the bottom sash provided with a wheel or pinion to engage with
the rack or screw, and means to operate same within the room substantially as
herein before described.
