I JOSEPH HENRY KNAUS of 5 Depot Street Fayette, Howard County, Missouri,
United States of America Mechanic, do hereby declare the nature of this invention to
be as follows:-
The object of my invention is to provide a device to insure the even, smooth and
uniform or equal movement of both sides of a drawer in sliding out of or into its
ways or guides, thus obviating the cramping and binding which so commonly occurs
in furniture drawers especially those which are of greater width than depth, when the
drawer is pulled out or pushed in unevenly, or one side of the drawer is pulled or
pushed more forcibly than the other.
My invention consists in combining with the drawer a rotary or roller shaft
arranged parallel to the front and back of the drawer, or at right angles to the line of
movement, and journalled in bearings in the drawer, and cords or other flexible con-
nections coiled several times around the shaft, one near each end thereof the ends of
the cords or chains being attached to a stationary part of the drawer-casing at the
back and front of the casing respectively so that when the drawer is pulled out the
roller moves with the drawer, and the one cord in winding off in rear of the roller
and winding on in front causes the roller to revolve, and the revolution of the roller
causes the cord at the other side of the draw to wind on the roller in front and
unwind in the rear to the same extent thus imparting to the drawer at that side the
same motion that it has at the side where the power may have been applied.
causes the drawer to always move equally at both sides, and insures a free and easy
passage, free from any cramping or binding.
This
To take the drawer entirely out of its frame, the roller is lifted out of the slots in
which it is journalled, and to permit this to be done notches are formed in the drawer
guides to receive the roller journals when the roller is lifted. Instead also of using
a roller-shaft, I may use a smaller shaft with a broad-faced grooved pulley at each
end, upon which the cords are wound, and instead of. using a cord, a chain or wire
may be used.

I, JOSEPH HENRY KNAUS, Mechanic, of 5 Depot Strect, Fayetto, in the County of
Howard, and State of Missouri, United States of America, 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 of my invention is to provide a device to ensure the even, smooth and
uniform, or equal movement of both sides of a drawer in sliding out of, and into, its
ways or guides, thus obviating the cramping and binding which so commonly occurs
in furniture drawers, especially those which are of greater width than depth, when
the drawer is pulled out, or pushed in, unevenly or one side of the drawer is pulled or
pushed more forcibly than the other.
My invention consists in combining with the drawer a rotary or roller shaft
arranged parallel to the front and back of the drawer, or at right angles to the line.
of movement and journaled in bearings in the drawer and cords or other flexible
connections coiled several times around the shaft, one near each end thereof, the ends
of the cords or chains being attached to a stationary part of the drawer-casing at the
back and front respectively, as hereinafter more fully described.
In the drawing, the figure is a perspective view of my improved drawer-equalizer
attached to a drawer, part of the casing being broken away.
In the drawing A represents the drawer, and B B the casing or frame in which
the drawer slides. C is a roller shaft arranged at the rear upper edge of the back
side of the drawer. This shaft has journals at its ends which revolve in bearings in
two notches a a in the sides of the drawer near the rear ends. At each end of the
roller and near the sides of the drawer, there is a cord or chain b wound several times
around the roller and fastened by a staple or tack to prevent slipping. The ends of
these cords are attached to the casing or frame of the drawer, one end to the back
part B and the other end to the front part B¹. This connection may be made in any
approved way,
such for instance as a staple or screw-eye or a hole bored through the
wood to receive the cord and a knot tied in the end of the same.
With such an arrangement of the cords, roller, and drawer, it will be seen that
when the drawer is pulled out the roller moves with the drawer and the cord in
unwinding in rear of the roller and winding in front upon it causes the roller to
revolve and the revolution of this roller causes the cord at the other side of the
drawer to wind on the roller in front and unwind in the rear, thus imparting to the
drawer at that side the same motion that it has at the side where the power may have
been applied. This causes the drawer to always move equally at both sides, and
ensures a free and easy passage, free from any cramping or binding,
To take the drawer entirely out of its frame, the roller is lifted out of the slots a;
and to permit this to be done, notches d d are formed in the drawer guides to receive
the roller journals when the roller is lifted. Instead also, of using a roller shaft, I
-may-use-a-smaller-shaft-with-a-broad-faced-grooved-pulley at each end-upon which
the cords are wound, and instead of using a cord, a chain or wire may be used.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. The combination, with a drawer and its casing, of a shaft journaled in the
drawer at right angles to the line of movement and a cord or other flexible connec-
tion, as described, arranged at each end of the shaft and wound around the same,
the said cords having their ends connected respectively to the front and back of the
casing, substantially as shewn and described.
2. The combination, with a drawer having slots a a and its guides having
notches & d, of a shaft journaled in the drawer at right angles to the line of move-
ment and a cord or other flexible connection, as described, arranged at each end of
the shaft and wound around the same, the said cords having their ends connected
respectively, to the front and back of the casing, substantially as and for the purpose
described.
