Improvements in Pulley-casings for Window-frames.
I, JAMES HALL FOOTE, of No. 18 Moorman Avenue, Cincinnati, Hamilton
County, State of Ohio, United States of America, 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:
The object and nature of my invention will be fully apparent from the description
and claims hereinafter contained.
In the accompanying drawings::
=
Figure 1, is a front elevation, partially in section, of the top portion of a window-
frame and sash with my improved pulley-casing in an operative position.
Figure 2, is an enlarged side elevation of the pulley-casing shown in Fig. 1,
detached from the frame, and Figure 3, is a top view of Fig. 2.
Figures 4 and 5 are side and top views, respectively, of a slight modification of
my improved pulley-casing..
Figure 6, is an enlarged transverse section through one side of a window-frame
provided with my invention, illustrating one mode of attaching it to said frame.
Figure 7, is a side elevation of a pulley-casing embodying my invention with the
pulley removed, and
Figure 8, is a vertical section on dotted line 8, 8, of Fig. 7.
My invention consists of a pulley-casing, A, adapted to fit suugly within the
usual mortise formed in the front casing, D, of the window-frame, said pulley-
casing having a rearward extension a of sufficient length to reach across the open
space or chamber formed in said frame, the point of said extension being so formed
as to be capable of being driven into the rear casing, E, of the frame.
The pulley, B, is suitably mounted within the casing, A, which latter is
preferably formed from one integral piece of sheet-metal which is cut away to form
the extensions, a, as shown; but, I do not confine myself to this specific form or
construction of pulley-casing, as the same might be formed of two pieces suitably
connected and having a rearward extension capable of being driven into the
window-frame.
Each extension, a, of my improved pulley-casing is so formed as to be capable
of being driven into the rear of the window-frame; and, with this object in view,
I preferably form one or more tangs, a², at the end of said extensions which will
readily enter the wood of said frame, as shown in Fig. 1, or they may be made to
pass entirely through the rear casing and clinched, as shown in Fig. 6.
The pivot-center of the pulley, being inward from a line vertical with the front
casing of the frame, will tend to retain the pulley-casing securely to place, as the
weight (not shown) on the sash-cord, b, will have a tendency to pull said pulley-
casing inward; but, if additional security is desired, the latter may have one or
more lips or projections, a³, cut or formed therein, as shown in Figs. 4 and 5, to
engage with the front casing of the window-frame.
The tangs, a, may be bent or twisted to any desired angle; and, if desired, said
tangs may be barbed or otherwise roughened to assist in securely retaining the
pulley-casing to position within the frame.
When constructed as shown, my improved pulley-casing is put to place by
passing the rear extensions, a, through the usual mortise formed in the front
casing of the frame, the casing A, being adapted to fit snugly within said mortise;
and, while said casing, A, is being driven to place within its mortise, the tang or
tangs on the end of extension, a, will enter the rear casing, E, of the frame, as
shown.

page_text: The advantages of my invention are apparent, being simple of construction,
cheap of manufacture and reliable in operation. The rear extensions of the pulley-
casing,, being affixed to the rear of the window-frame, affords two rigid bearings
and connections for the pulley-casing, which latter cannot be readily displaced or
loosened by reason of the sash-weight coming into contact therewith.
The construction of my improved pulley-casing dispenses with the use of all
screws, and is readily and quickly secured to place within the window-frame, as
herein before specified.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
olaim is:-
(1.) A pulley-casing consisting of the main body portion, A, having the rearward
side extensions a, each terminating in a sharpened "point capable of being driven
into the solid wood of the frame, for the purposes set forth.
(2) As a new article of manufacture, a pulley-casing stamped from sheet-metal
and bent to form the main body portion, A, and rearward extensions a, the latter
having a tanga, substantially as set forth.
Dated this 15th day of September 1894.
