TOOMPLETE SPECIFICATION.
Improvement in Mechanism for Lifting, Lowering, and Looking
Window-sashes and other Articles.
I DONALD FLETCHER, Miner and Broker of Cripple Creek in the County of
El Paso and State of Colorado, U.S.A., do hereby declare the nature of my
invention for Improvement in Mechanism for Lifting, Lowering and Locking
Window-sashes and other Articles and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
The chief object of my invention is to enable an invalid to control the ventilation
and temperature of his room without getting out of bed.
For this purpose,
I arrange near the bedside a receptacle containing means for raising and lowering
a window-sash, said receptacle having a lid provided with a lug which engages the
said means and lucks the sash when the lid is closed.
Figure 1, of the drawings represents in plan view the mechanism, with the sash
and a part of the window-frame; Figure 2, a vertical section through the same;
Figure 3, a detail elevation of plate A and Figure 4, a similar view of plate B.
These plates are set flush in the window-sasha and the pulley stile y respectively.
Plate A has at top and bottom arms a, perforated at their ends to let the
operating cords e e' through them. Plate B is slotted at 6' to guide the arms a as
the sash moves up and down.
The receptacle D near the bedside may be either fixed or movable and contains
the winding drum d, from which the said cords e e¹ pass to the sash. A handle-
wheel d' rotates the said drum, to wind or unwind these cords. The lid J of the
said receptacle is provided with a lug L, which enters between the spokes of the
said wheel when the lid is closed; thereby locking the sash.
When the lid is raised, the occupant of the bed easily reaches, and turns,
the handle-wheel to move the sash for opening or closing the window more or less.
By shutting down the lid again, be locks the sash in the position thus given.
The cords ee are preferably concealed in some part of the structure of the
building.
The sash is counterbalanced by weight e and its counterpart in the other side of
the window-frame. No one out of the room can interfere with or operate the
lifting, lowering and locking mechanism.
Its use of course is not confined to invalids, nor to raising window-sashes only.
The construction may vary, also, in many respects without departing from my
invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1st. In sash-lifting, lowering and locking mechanism, the combination of the lid J,
having locking lug L, with the drum d, handle-wheel d and cords e e', the said
cords being connected to a window-sash..
2nd. A receptacle having winding mechanism contained therein and a lid provided

page_text: with means for locking said mechanism when said lid is closed, the sash or other
article or structure which is to be lifted or lowered and locked being connected by
cords to the said winding mechanism.
Dated this 14th day of December 1896.
