page_text: Improvements in Sliding Windows.
I, JOHN HISCOCK, of Aysgarth, Sidcup, in the County of Kent, Gentleman,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in sliding windows and consists in
providing means whereby the use of sash-lines is dispensed with, and the opening
and shutting of such windows rendered more easy, while at the same time the
rattling of the window sashes is prevented.
In carrying my invention into practice I provide the opposing faces of one
of the vertical sides of the upper and lower. sashes with a suitable metal rack,
between which is provided a suitable pinion, the teeth of which mesh with the
racks aforesaid. The said pinion is pivotted to a suitable portion of the window
frame between the window sashes, and by gearing with the said racks, in the
beforementioned manner, will securely maintain the sashes at any desired point.

Improvements in Sliding Windows.
I, JOHN HISCOCK, late of Aysgarth, Sidcup, in the County of Kent, and now
residing at Milton House, Stow Hill, Newport, Monmouth, Gentleman, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in sliding windows, and has for its
object the provision of means whereby, the employment of sash lines and weights
is dispensed with, and the opening and shutting of the windows rendered an
easier matter than heretofore, a further object being to provide means whereby
both windows can be opened simultaneously, or one sash may be opened a pre-
determined distance, independently of the other.
And in order that this my said invention may be the more readily understood
and carried into practical effect, reference is hereby made to the accompanying
sheet of illustrative drawings, wherein:
Fig. 1 is a front elevational view of my improved sliding window, Fig. 2 a
section of the sashes shewing the rack and pinion arrangement.
Fig. 3 is a front elevational view of one of the sliding racks in the elevated

page_text: position it assumes when the upper sash is lowered independently of the lower
sash. Fig. 4 is a sectional view of a detail of the invention, and Fig. 5 an
elevational view of one side of the sashes with my invention applied thereto.
Referring to the drawings, wherein like letters of reference indicate corre-
sponding parts throughout the several figures, a, b, represent the upper and lower
sliding sashes, respectively of a window.
In the opposing sides of the vertical side rails a¹ b¹ of the sashes, racks c d
are secured, the upper racks c being rigidly attached to the side rails a while
the lower racks d are adapted to slide in grooves 62 formed in the said side rails 6¹
of the lower sash b.
Pinions e are pivoted to the window frame between each sash, such pinions
engaging with the racks c and d on the upper and lower windows, as shewn by
Fig. 2. When one sash is raised, the pinions e are caused to rotate upon their
axes and thereby lower the other sash, and vice versa.
In order to allow of the upper sash being lowered to a convenient degree
without simultaneously raising the lower sash, I allow the lower racks da limited
sliding movement, so that when the upper sash is lowered, the said racks are
slid upward in their grooves without raising the lower sash.
The sliding movement of the racks d is limited by means of sliding bolts f
which are adapted to enter grooves f¹ in the sides or other convenient part of
the upper sashes when such bolts are pushed inward, these said bolts, in con-
junction with the upper shoulders of the grooves f1 constituting stops.
When it is desired to open both the upper and lower sashes simultaneously,
the racks d are restored to their normal or lowered position, by raising the lower
sash, and the said racks are then secured in such normal position by means of
set-screws g, acting, through the side rails 61, upon the backs of the said racks.
The usual parting beads (not shewn) are so arranged as to conceal the racks
from view.
{
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
-
1. The improvements in sliding windows, consisting in racks fixed to the
faces of the side rails of the upper sash and similar racks slidingly held in
grooves in the opposing faces of the side rails of the lower sash, and pinions
pivoted to the window frame and gearing between such upper and lower set of
racks, said lower racks having a sliding movement of a predertermined distance,
when the upper sash is lowered, such sliding movement being limited by a bolt
taking into a groove in one of the side rails of the upper sash, while said sliding
racks are capable of being held rigidly to the side rails of the lower sash by
means of set-screws passing through the side rails of the lower sash and adapted
to abut against the rear sides of the said racks, all arranged, combined and
operating, substantially as described and as illustrated.
