COMPLETE SPECIFICATION.
Improvements in Sash and like Pulleys.
I, ULYSSES GRANT MCQUEEN, of 150, Nassau Street, in the City, County, and
State of New York, United States of America, Inventor, 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 relates to pulleys and particularly to that class known as sash
pulleys adapted to be used in connection with window sash, and for similar
purposes; and the objects of the invention are to provide a pulley of this class
which can be employed where there is very small head room or where the distance
above the lintel of the window frame is very short, thus requiring a pulley, which
will extend only a short distance above the lintel, also to produce a pulley of this
character, provided with an extension base or support, which is constructed to
rest within a recess formed in the pulley stile thereby centering all of the strain
upon the stile, and by means of the base extending thereinto, the pulley is rigidly
supported, and prevented from lateral movement; and with these and other
objects in view, the invention consists in the construction and arrangement of
parts, hereinafter more fully described in the specification and illustrated in the
accompanying drawings; in which :-
Figure 1 is a side elevation of this improved pulley, showing the same in
operative position;
Figure 2 is an end view of the pulley in operative position; and
Figure 3 is a perspective view of the pulley detached;
Figure 4 is a side elevation of a modified form or mullion pulley, showing
the same in operative position.
Similar characters of reference designate like parts throughout the several
views.
Referring to the drawing, the reference numeral 1, indicates the lintel of an
ordinary window frame, the end of which is cut away or slotted as shown at 2,
and the lower face or under side of the lintel is provided with a recess 3; to
receive the extended portion or end 4, of the pulley casing 5, as hereafter described,
and the bifurcated or slotted extremities of the lintel have formed therein notches
or recesses 6, adapted to receive the upper end of the pulley stile 7, which is
provided with a notch or recess 8, as clearly shown in Figs. 1 and 2, of the
drawings.
The pulley casing 5, consists of a main portion or hood 9, within which is re-
volvably mounted a pulley wheel 10, having either a flat or grooved periphery,
adapted to receive the suitable sash cord, band or chain 11, and the main portion or
hood 9, is extended to form the end 4, adapted to be secured within the recess 3,
on the under side of the lintel, in which position it is secured by a screw or
bolt 12; and the casing is provided with a depending projection or extension
base 13, which is securely retained within the notch in the pulley stile, and
by means of this construction a firm bearing is afforded for the projection 13,
and the casing is securely held against lateral movement, while the upward
TD 0.71

page_text: movement of the sash is not decreased, as the projection 13, is of the same width
as the pulley stile 7, and the sash can be elevated until it contacts with the under
face of the lintel 1, whereby it will be seen that a great economy of space is
effected..
The pulley casing is provided at the junction of the extended portion 4, and
the depending projection 13, with an opening 14, through which the sash cord 11,
passes, and the end 15, of the sash cord 11, is connected in any suitable manner
with the upper bar or head of the sash and to the end 16, of the sash cord 11,
is attached a weight or other suitable device.
By means of the specific construction of the parts herein shown and described,
less head room or space above the lintel of the window frame is required, which
is most essential in the present architectural constructions, and the upward move-
ment of the sash is not decreased, but the same can be forced upward into contact
with the under surface of the lintel of the window frame, as before explained,
also greater rigidity is secured for the casing, and the under surface of the
lintel is not marred; all of which characteristics constitute the most essential
advantages, as has been demonstrated by years of actual practice.
In Fig. 4 of the drawing, I have illustrated a modified form, adapted for use
with twin windows or similar constructions, where only one weight is employed
consisting of a mullion pulley 20, having a casing 21, preferably constructed in
the general form shown in said Fig. and within this casing is journaled a
pulley 22, having a flat or grooved periphery and adapted to be used with a sash
cord, band or chain, as desired, and the pulley 22, preferably extends into the
bottom of the casing so that the periphery thereof is approximately on a line with
the under face of the lintel 23, of the window frame.
The casing 21, is preferably provided with a depending central portion 24,
and with laterly extending shoulders 25, which rest upon the upper surface of the
window frame, as shown, and the central depending portion of the casing projects
through a suitable opening in the lintel 23, and one side of said casing is open
as shown at 26, and said casing is also provided in one side of the central depending
portion 24, with an opening 27, through which a sash cord, band or chain 28,
passes, thence over a pulley 22, and out through the open side 26, of the casing,
as clearly shown in Fig. 4 of the drawings.
By the construction herein shown and described a mullion pulley is provided
which greatly economises the head room or requires a minimum amount of space
above the lintel of the window frame, which is a most essential point in the
present architectural construction as will be readily understood by those skilled
in the art, to which this invention appertains; and also the pulley is securely
held against displacement, and the weight of the sash is brought directly upon
the upper surface of the lintel of the window frame, and for the most part directly
over the pulley stile.
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. A pulley provided with a casing having an attaching extension adapted to
be secured to the under face of the lintel of a window frame, said casing extending
above said extension to form a hood, and having a depending extension-base or
support in a plane below said attaching extension and a pulley mounted within
the hood and projecting into the extension-base or support so that the periphery
thereof lies below the lintel.
2. The combination with a slotted lintel having a recessed under face and a
notched pulley stile, of a pulley casing having an attaching extension adapted
to be secured in said recessed under face of the lintel, said casing projecting above
said attaching extension, and having a depending extension-base or support in a
plane below said attaching extension adapted to be secured within the notch in
the pulley stile, and a pulley mounted in the hood and the projecting into the

lintel of the window.
