CHARLES A. RIVERS AND FRANCIS B. STUART, OF EL PASO, TEXAS.
CLEANING DEVICE.Specification of Letters Patent.
Patented Mar. 29, 1921.
Application filed March 4, 1919. Serial No. 280,561.
To all whom it may concern:
Be it known that we, CHARLEs A. RivEis
and FRANCIS B. STUART, both citizens of the
United States, and residents of El Paso, in
5 the county of El Paso and State of Texas,
have invented certain new and useful Im-
provements in Cleaning Devices, of which
the following is a specification.
This invention relates to cleaning devices,
10 and more particularly to a cleaner for wind
shields, car windows, automobile headlights,
etc.
In rainy or snowy weather, the face of the.
wind shield glass becomes covered with
15 snow or rain and rendered more or less
opaque so as to obscure the vision of the
driver. This frequently causes serious ac-
cidents, sometimes resulting in the demoli-
tion of the vehicle and loss of life.
20 It is the primary object of the present in-
vention to provide a very simple and inex-
pensive cleaning attachment which can be
easily and quickly applied to the wind
shields of different makes of vehicles and
25 readily operated from the driver's seat to
remove snow, mist, or dust from the front
surface of the wind shield glass.
It is also an important object of the in-
vention to provide such a cleaning device
30 which may be applied to the wind shield
without marring the frame thereof or neces-
sitating structural changes or alterations of
any character.
The invention contemplates the provision
35 of a very novel means for mounting the
cleaning device upon the wind shield frame,
embodying supporting brackets for clamp-
ing ngaoement upon opposite sides of the
t'ra me, and tensioning means connecting the
40 brackets and securely holding the same in
their applied positions, which means also
constitutes a guide for the cleaning member.
It is likewise one of the detail objects of
our invention to provide improved means
45 for variably adjusting the pressure of the
cleaning member upon the face of the glass
to compensate for wear thereof and assure
proper cleaning action at all times.
Having the aforementioned objects in
50 view, the present invention comprehends
certain novel and improved combinations
of mechanical elements, and the structural
characteristics thereof, as will be more fully
developed in the following description and
55 subsequently incorporated in the subjoined
claims.In the accompanying drawings:
Figure 1 is a front elevation of an auto-
mobile wind shield of a conventional and
well known construction illustrating one 60
embodiment of our invention as applied
thereto;
Fig. 2 is a horizontal sectional view taken
on the line 2-2 of Fig. 1;
Fig. is a vertical section taken on the 65
line 3-3 of Fig. 1;
Fig. 4 is an enlarged detail horizontal sec-
tion of one side of the wind shield frame
illustrating the manner of mounting the
movable cleaning member ; 70
Fig. 5 is a fragmentary side elevation of
the wind shield.
Referring in detail to the drawings,
wherein like reference characters designate
corresponding parts throughout the several 75
views. 5 designates the marginal frame of
a wind shield, the upper section of which is
pivotally mounted as shown at 6 between
the vertical bracket members 7 for swing-
ing movement in the usual manner. 8 desig- so
nates the glass which is affixed in the wind
shield frame.
The present invention is adapted to be ap-
plied to the frame of the upper wind shield
section and in its preferred embodiment in- 85
cludes the bracket members 9. Each of
these bracket members is formed with a
forwardly projecting arm 10 and at one end
of this arm a laterally curved extension 11
is provided, the free end of which is adapted 90
to abut against the front face of the wind
shield glass 8 at a point closely adjacent to
the marginal frame thereof. A second
curved extension 1.2 projects in a relatively
opposite direction to the extension 11 from 95
the arm 10 and is' of appreciably greater
len ith than the extension 11. These curved
extensions closely embrace and-engage upon
the frame of the wind shield, the extension
12 engaging around the outer side of the 100
frame and upon the rear side thereof. This
extension ,12 is formed in its outer face with
a groove or channel indicated at 13, the pur-
)OSe of which will be presently disclosed.
To the end of the arm 10 of one bracket 105
member. a resilient metal wire 14 is securely
attached. The other end of this wire is con-
nected to one end of a threaded bolt 15
which is loosely engaged through an aper-
ture in the arm 10 of the other bracket mem- 110
ber. A nut 16 is threaded upon the ex-
tremity of this bolt and bears against the1,373,096.
