Complete Specification Left, 7th Apr., 1896-Accepted, 9th May, 1596
I, LEWIS ALEXANDER HEINZERLING of Monte Cristo, County Snohomish,
State of Washington, U.S.A., Mechanic, do hereby declare the nature of this
invention to be as follows :-
In this invention there is fixed at one or both sides of the window frame a
vertical bar or plate provided with a number of inclined planes or teeth in which a
vertical bar having similar but oppositely inclined teeth may be slid up and down
and so as to be moved laterally to the right or left. The opposite vertical edge
of the movable bar takes against the window sash either direct or through a friction
strip of india rubber or other suitable material. By means of a stud fitted in the
movable bar and guided in a slotted plate or bracket said bar, by its teeth working
in the teeth of the fixed bar, may be moved outwards to press against and lock the
sash or inwards to release the sash or the sash may be locked and held in the
locked position by the gravity of the movable bar and moved into the unlocked
position by raising the movable bar through the stud and then turning the stud
partly round to engage, by ribs projecting from said stud, the top of the slot in the
bracket.

I, LEWIS ALEXANDER HEINZERLING of Monte Cristo, County Snohomish,
State of Washington, U.S.A., Mechanic, 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 this invention is the provision in sash holders of an improved
friction holding device which will create a frictional bearing substantially
throughout the entire length of the sash and in connection therewith suitable
means for locking the device out of engagement with the sash.
In the accompanying drawing which illustrates the invention
Fig. 1 is a vertical section of a window frame and sash. Fig. 2 a similar view of
the window frame and Fig. 3 a detail of the actuating portion.

page_text: A is a window frame say of a railway carriage. B the sash. C the outer bead
D the side of the casing removably secured on the frame.
In the rear of the side D between the same and the casing and at a point back
from the sashi is a vertical strip E having its outer edge formed with a continuous
series of teeth e having horizontal lower edges and inclined upper edges.
Between the edge of the strip or bar E and the sash B is a loosely fitted friction
bar F which has on its inner edge a series of inclined teeth f corresponding with
the teeth e but inclined in an opposite direction. The bar F is shorter than the
bar E and allows a vertical side movement between the side D and the frame.
Its outer edge is normally arranged in contact with the side of the sash B.
The side D has an inclined elongated slot d terminating in a circular opening d¹,
a suitable metallic cap being placed around the slot and opening as indicated
at d².
G is a raising and locking device having a shank 9 passing through and pivotally
secured in an opening formed in the locking bar F. g is a thumb disc from which
project ribs g. The two ribs may freely rotate in the circular opening d' and also
slide in the elongated opening or slot d.
On the outer edge of the locking bar F is fitted a suitable friction strip f2 of
rubber or leather.
In operation, the raising and locking device is turned so that the ribs 92 will
move in the elongated slot d. The locking bar is pressed down and the window
which has previously been raised is firmly locked in its elevated position. When
it is desired to lower the window the raising and locking device is moved up and
turned at right angles so that the ribs will strike the lower walls of the aperture
in which they are located and thereby hold the locking bar in an elevated position.
When the window is to be locked, the opposing inclined teeth f and e will tend to
separate by gravity forcing the edge of the locking bar out, and the same can only
be forced in by an upward movement, as is obvious.
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
claim is :-
In a sash holder, the combination with the window sash and frame, of the casing
side D, the fixed bar E between the frame and side D and having a series of
inclined teeth e on its outer edge, the locking bar F normally resting against the
sash and having a series of inclined teeth f on its inner edge, inclining in a direction
opposite the inclination of the teeth e, the raising and locking device G pivotally
secured to the locking bar and projecting through an opening in the side Cand adapted
to work vertically in said opening, its central portion being provided with laterally
extending ribs, a thumb disc beyond the ribs, and a plate on the side arranged at
an incline and formed with an elongated opening and a circular opening above the
elongated opening in which the rib portion of the locking device works, substantially
as described and shewn.
Dated this 7th day of April 1896.
