1 Claim.
(Cl. 15-237)
pensive device by which lforeign material such as
lmud and other objectionable substances adhering
it will form a locking means as shown in Fig. 2.
In plate I are two horizontal holes I0 through
which screws or bolts may pass, that provide
means for securing the scraper device to the step
5 to footwear can be removed therefrom with the
utmost ease and dispatch to the end that the
footwear of a person about to enter a house, auto
or other location. In scraper plate 2 are two
holes I 0A which form a means through which a
screw driver can be inserted to contact screws in
This invention relates to scraping devices for
footwear and has for its object a simple inex
mobile, or the like can be thoroughly cleaned of
such foreign material and thus prevent soiling the
10 floor, rugs, or floor coverings as well as elim
inating unsanitary conditions, especially in rural
districts, 'resulting from carrying foreign material
accumulated on the footwear,y from the stables or
pastures, into the dwelling.
It is a well known fact that there are a great
many forms of scraping devices for this purpose,
but it is the object of this invention to construct
a device in which the scraper blade may be actu
ated by means of levers and springs so that when
20 the scraper blade use is not required it may be
retracted from obstruction, and by the use of a
simple mechanism be brought into position for
use.
25
Because of this actuating means it is self
cleaning.
The special construction and arrangement of
the parts of this invention are illustrated in the
accompanying drawing of which; Fig. l is av front
plan view of the device showing scraper plate
retracted. Fig. 2 taken on line 2-'2 of Fig. l
30 is a sectional side elevation showing the arrange
ment of the parts. Fig. 3 is a top plan view
of the device showing the blade retracted. Fig. 4
illustrates a sectional side elevation of the scraper
plate and the tension spring. Fig. 5 shows a sec
35 tional side elevation of the scraper plate retain
ing member with the scraper plate removed, taken
on line 5-5 of Fig. 3.
Throughout the drawing and description the
same number is used to refer to the same part.
40
Considering the drawing, this invention con
sists of an angular piece of sheet steel I of rea
sonable strength, which is secured to a step or
other convenient location and extended downward
and at right angle thereto. On this downward
45 portion are four overlapping members 3 as shown.
In the channel of these overlapping members is
movably secured a scraper plate. 2, which is re
tained in a vertical position by the overlapping
members 3 of plate I. Secured to plate I and
50 extending vertically and at right angles thereto
is a fulcrum piece 4 in which the scraper plate
actuating means 5 pivots. The inner end of
actuating lever 5 is pivotly secured to the
scraper plate 2 by means of a bolt Ii. Bolt 6
55 moves vertically in an elongated slot 'I which
forms a limit movement slot. In plate 2 is a
horizontal slot 8 which engages protrusion 9 of
plate I so that when the scraper plate is raised
holes I0 in order to tighten the same into place
when scraper plate is partly raised. The angular
metal piece I is also provided with the screw holes 10
II, as shown in Figs. 3 and 5. After said screws
have been tightened into place scraper rplate 2
is now free to be raised or lowered.
The rear
ward extending portion of member I carries holes
II providing another means for securing plate I 15
to its location as shown in Fig. 3. The scraper
plate 2 is frictionally held against plate I by
means of a spring I2, a friction washer I3, a
retaining washer I4 and a nut I5 on bolt 6 as
20
clearly set forth in Fig. 4.
In the operation of this invention, the scraper
plate 2 is raised so that protrusion 9 slips into
slot 8, thus holding scraper plate secured in a
raised position ready for use, by a downward pres
sure of the foot upon lever 5, as shown by the 25
broken lines in Fig. 1.
To retract the scraper plate 2, an outward and
downward pressure is applied'to the top of the
scraper plate which disengages protrusion 9 from
slot 8 and allows plate 2 to be readily collapsed 30
into its original position on plate I.
Having now described this invention, I claim:--A shoe scraper comprising in combination, a
supporting plate, a scraper plate located next to
and upon one side of the supporting plate, said 35
supporting plate being provided with guiding de
vices wherein said scraper plate may be moved
upward and downward, the said guiding devices
being constructed to permit a limited movement
of said scraper plate towards and from the sup 40
porting plate, a lever, a pivot pin attached to said
lever and scraper plate, a coil spring borne by
said pin and arranged against said supporting
plate whereby said lever and scraping plate are
yieldingly connected, said supporting plate hav 45
ing a slot for the passage and movements of said
pin, said supporting plate being provided with a
fulcrum piece, said piece being constructed and
arranged to engage the lever and afford a fulcrum
therefor, said lever extending beyond the sup 50
porting plate and being operable by foot pres
sure, said supporting plate having a transverse
protrusion, and said scraper plate being con
structed with a transverse opening and being
movable by said coil spring into detachable en 55
gagement with the said protrusion to hold said
scraper plate in raised position.
