My present invention relates to automobile
window sash mechanisms, and more particularly
to improved window sash elevating mechanism.
The principal object of my invention is an im
-5 proved automobile window sash mechanism;
Another object is a parallel elevating and loWer—
ing mechanism for sliding window sashes;
Still another object is the combination of a
counter-balanced parallel elevating and lowering
10 mechanism for sliding window sash, and
Other objects and ‘novel features comprising
the construction and operation of my device will
appear as the description of the same progresses.
In the drawing illustrating the preferred em
15 bodiment of my invention:
Fig. l is a side elevation of the apparatus re
moved from an automobile door;
Fig. 2 shows the opposite side of the elevating
and lowering mechanism, as viewed in Fig. 1, a
portion of the sash pane being broken away for
convenience, and
Fig. 3 shows a cross section taken on the line
3-3 of Fig. 1.
In Fig. 1 I have indicated at Ill, in broken lines,
25 a panel of the door of an automobile.
At II I
have indicated the opening of the window, also
in broken lines, the window being shown in a
closed position. The sash pane l2 of the window
is provided with a bottom channel member I3, as
30 is usual in window construction of this type. At
two separated points on the channel member I3
I have attached, as by welding, two right-angled
bracket members I4 and I5.
At I6, I have indicated a curved plate member
35 which is bolted at I‘! to the panel member Ill.
The entire mechanism is carried on the bolts IT.
The apparatus shown in the drawing is pro
vided with certain locking mechanism inclosed
within the casing I8 which cooperate with the
40 lever I9 and the toothed periphery 20 on the
?xed plate I6. This locking apparatus is fully
disclosed in my copending application entitled
Automobile window sash lock, ?led September 3,
1937, Serial Number 162,283, in which the mecha
45 nism with which this application is concerned is
also disclosed.
This is a division of the men
tioned application. For the purposes of. the pres
ent application, the ?xed plate 20 may be of any
shape and without the toothed periphery 20.
50 Also the lever I9 may be considered as being at
tached to the bell-crank lever 2I in a permanent
manner.
Through the plate I6 is journalled a shaft 22
the front end of which is slotted to receive the
55 counterbalance spring 23 the other end of which
squared on the portion which protrudes beyond
the plate l6 and is ?tted in a squared opening in
the lever 21. A washer 25 and machine screw 26
are provided to hold the shaft collar 21 tightly
against the plate I6 thereby maintaining the lever
2| and plate I6 in contact with each other.
At 28 I have provided a second bell-crank lever
reversally positioned with respect to the bell 10
crank lever 2|. The long leg of the lever 28, as
shown at 29, is slidably pivoted at 30 in the hori
zontal slot 3| located in the bracket I4. The
bracket I5 is similarly provided with a hori
zontal slot 32 which is adapted to receive a pivot 15
pin 33 which is ?xed in the lever 2| and jour
nalled through the lever 28. A top extension
member 35 is located on the lever 28 and is
adapted to bear against the vertical leg of the
bracket I5 for the purpose of maintaining the
apparatus in a braced relationship with the
plate I6 thereby preventing such apparatus from
becoming cramped when in operation. Below the
shaft 22 and a part of the plate I6 I have pro
vided a hanger 36. A lower arm 31 is provided
on the lever 28. The connecting lever 38 is
pivoted at 39 to the lever leg 31 on one end and
at 40 in the hanger 36. The center distance be
tween the shaft 22 and pivot pin 40 is equal to
the distance between the pin 33 and 39 in the
lever 28. Also the vertical axis taken through
the centers of the pins 33 and 39 is parallel to the
vertical axis of the centers of the shaft 22 and
pin 40.
-
When the horizontal lever 45 which is pivote
at 46 to the lever I9, is pulled to the right or left,
the lever 2I applies force at the pin 33 and ele
vates or lowers the glass I2 thereby opening or
5
closing the window, as the case may be.
With window glass which is wider in a hori
zontal direction than in a vertical direction it is
necessary that the sash pane, as I2, be moved up
and down in a perfectly vertical direction other
wise it will tilt to one side or the other and jam
in the slide-ways of the door‘ frame. In my
present arrangement the parallel bar 38 main
tains the horizontal leg of the lever 28 in a hori
zontal plane at all times and the forces exerted
primarily on the pin 33 are partially transposed
to the pin 30 in the bracket I4 thereby giving the 50
glass I2 a vertical movement with equal forces
applied at two separate points. An illustration
of the change in position of the mechanism is
shown in dot-and-dash lines in Fig. 1 showing the
lowermost position of the apparatus.
