Dinner Lifts, and other similar Contrivances.
I, WILLIAM FRANCIS LENNON of 124 East 84th Street, New York, in the
County and State of New York, United States of America, Builder, do hereby
declare the nature of this invention to be as follows:-
My Invention relates to that class of balances wherein each weight is formed
with a rack and is connected with a rack on the window sash by an intermediate
pinion fitted in an opening. formed in the window stile, and my invention consists
principally in forming the weights with guide flanges to act in connection with the
boxes in which the pinions are journaled, or other projections upon the inner
surfaces of the stiles of the window frame, for guiding the weights in their up
and down movements in the weight channels.
The Invention also consists of the weights formed with guides in combination
with the pinion boxes constructed to project into the weight channels for guiding
the weights.
The invention further consists of an inner or false stile constructed with a
division strip to separate the weights, and also to form the weight channels, and
the invention finally consists of the construction, arrangement and combination of
parts.
The weights are each cast with a rack and of a length about equal to the length
of the window sash, and upon each side of the rack is formed a guide flange and at
each side of the rack is also formed a groove, but these may be omitted if desired.
In the back of each weight is formed a channel in which more or less lead or other
heavy material may be placed to suit the weight to the weight of the window.
The window sashes are each provided at their side edges with a rack and in
openings formed in the stile are fitted boxes, in each of which is journaled a small
pinion, and these pinions mesh with the racks in the sash, and the racks on the
weights, so that the movement of the sash up or down will communicate a reverse
motion to the weights which thus balance the sash.
The side pieces or plates of the pinion boxes are of greater width than the
thickness of the stile and serve in connection with the flanges of the weights to
guide the weights in their up and down movements and prevent them from lateral
displacement; and when the weights are formed with grooves at the sides of the
racks I shall extend the side plates past the pinions so that they will reach into
said grooves thus causing the rack to always properly mesh with the cogs of the
pinions.

page_text: An inner or false stile is formed or provided with a central strip which
separates the weights. By preference this inner stile is grooved or rather made
F shaped in cross-section. The grooves together with the stile and the outside
facing piece form the weight channels to enclose the weights.
By the construction described the weights are practical in operation, and cheap
to construct and are not liable to get out of order, and by using the inner or false
stile, no back lining is required in the frame, and the ordinary inside casing is
dispensed with, the false stile being attached to the stile by screws in the parting
strip grooves.
I do not confine myself to the application of this counterbalance weight to
windows, as it is applicable to elevators, dinner lifts, and to various other devices.

I, WILLIAM FRANCIS, LENNON, of the City, County, and State of New York,
United States of America, Builder, 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:—
My Invention relates to that class of sash-weights or balances wherein each
weight is formed with a rack and is connected with a rack on the window-sash by
an intermediate pinion fitted in an opening formed in the window stile, and my
Invention consists principally in forming the weights with guide flanges to act in
connection with the boxes in which the pinions are journaled or other projections
upon the inner surfaces of the stiles of the window frame, for guiding the weights
in their up and down movements in the weight channels.
The Invention also consists of the weights formed with guides in combination
with the pinion boxes constructed to project into the weight channels for guiding
the weights.
The Invention further consists of an inner or false stile constructed with a
division strip to separate the weights, and also to form the weight channels; and
the Invention finally consists of a locking device arranged to act in connection with
the pinion for locking the sash closed or at any desired elevation.
Reference is to be had to the accompanying drawings forming a part of this
specification in which similar letters of reference indicate corresponding parts in all
the figures.

page_text: Figure 1. is a broken front elevation of a window and window-frame having my
Invention applied thereto, the lower sash being shown partly raised; figure 2. is an;
enlarged sectional plan view of one side of the window and frame, taken on the
line xx of figure 1; and figure 3. is a similar view showing the locking device.
I will describe one side of the window and window frame, the other being
similar.
The window is composed mainly of the stile A, outside stop casing B to which.
the blind or hanging stile C is secured, and the, casing piece D. The stile A. is
grooved at a to receive the parting strips E and to the inner surface of the stile, A
is secured, by screws b or other fastenings passed through the stile in the groove a,
the inner or false stile F which is formed or provided with the central strip f
which separates the window weights G G. By preference the inner stile F is
grooved at f1 f¹ or rather made F-shaped in cross-section formed with the said
central strips f and said central strip f and side strips f². The grooves f1 f1.
together with the stile A and the outside facing piece B form the weight
channels G¹ G¹ to enclose the said window-weights G G. The weights G are of
metal each cast or formed with a rack c and of a length about equal to the length of
the window sash H and upon each side of the rack is formed a guide flange c' and
at each side of the rack is also formed a groove c² but these may be omitted if
desired. In the back of each weight is formed a channel d in which more or less.
lead or other heavy material may be placed to suit the weight to the weight of the
window. The window sashes H are each provided at their side edges with a
rack J, and in openings K formed in the stile A are fitted boxes L in each of which
is journaled a small pinion M and these pinions mesh with the racks L on the sash
and the racks c on the weights so that the movement of the sash up or down will
communicate a reverse motion to the weights which thus balance the sash. The
side pieces or plates e of the boxes L are of greater width than the thickness of the
stile A and serve, in connection with the flanges c¹ c¹ of the weights G, to guide
the weights in their. up and down movements and prevent them from lateral
displacement; and when the weights are formed with the grooves c² at the sides
of the racks C I shall extend the side plates e past the pinions, so that they will.
reach into the said grooves as shown clearly in figure 2 thus causing the rack c to
always properly mesh with the cogs of the pinions M.
In figure 3, I have shown the lower sash arranged to be locked by a bolt N¹
fitted in a tube or casing n inserted in an opening in the inner casing piece D and
stile A. The inner end of the bolt is formed with a narrow projection n' adapted
to enter between the cogs of the pinion M when the bolt is forced inward for
locking the sash. The casing K in which the pinion M is journaled is formed with
an opening n through which the inner end of the locking bolt passes. The bolt
may be moved longitudinally in the casing n by various means to cause it to
engage and disengage the teeth of the pinion, but for this purpose I prefer to form
the bolt with depressed cog-teeth o and employ the cogged or fluted rod O fitted in
a transverse opening formed in the stop-bead N and stile A so that the cogs or
ribs of the rod mesh with the cog-teeth o as will be understood from figure 3, so
that by simply turning the rod O by the knob o¹ the bolt N may be moved out or
in to lock or unlock the window.
I do not confine myself to the application of this counterbalance weight to.

contrivances.
