PROVISIONAL SPECIFICATION.
An Improved Scraper or Cleaner for Boots and Shoes.
I FRIEDRICH AUGUST CAHN of Hanover Germany, Manufacturer do hereby
declare the nature of this invention to be as follows:-
This invention relates to a boot scraper or cleaner for removing wet and mud
from the soles of the boots by passing them once across the scraper or cleaner.
My invention consists of a number of alternate plates of rubber (or canvas and
rubber) and metal set edgewise and bolted or otherwise clamped together to form
a scraper block the scraping surface of which consists of the edges of the rubber
plates which project somewhat above the metal ones. The rubber plates besides
standing above the metal ones have undercut shoulders near their ends which stand
up still higher and form side scrapers for the edges of the boot soles. The centre
metal plate which is thicker than the others is provided with a pair of posts which
fit into sockets in a trough like base plate which catches the moisture and mud
scraped off the boot soles.
The appliance may be either portable, or fixed like an ordinary house scraper in
which case the trough may be omitted.

COMPLETE SPECIFICATION.
An Improved Scraper or Cleaner for Boots and Shoes.
I, FRIEDRICH AUGUST CAHN, of Hanover, Germany, Manufacturer, 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:-
This invention relates to a boot scraper or cleaner for removing wet and mud
from the soles of the boots by passing them once across the scraper or cleaner.
My invention consists of plates of rubber (or canvas and rubber) and metal set
edgewise and bolted or otherwise clamped together to form a scraper block, the
scraping surface of which consists of the edges of the rubber plates which project
somewhat beyond the metal ones, the plates having undercut shoulders near their
ends which form side scrapers for the edges of the boot soles.
Reference is to be had to the accompanying drawings, forming part of this
Specification, wherein Figure 1 is a top plan, Figure 2 a half-sectional side view,
and Figure 3 a half-sectional end view.
A number of rubber plates a (with or without canvas embedded therein) are
combined with metal plates c so as to form a scraper block, the ends of the plates
being received and clamped between the flanges of standards n provided with
clamping screws attached to the base m. Each rubber plate a is clamped
between two metal plates c and the ends of the metal plates are thickened or
shouldered as at c' so that when two or more sets of three plates (two metal and
one rubber) are thus assembled together, gaps d will be left between them for the
dirt to fall through, as shewn. From the top edges of both the rubber and metal
plates rise undercut shoulders a', near their ends, so as to constitute side scrapers
for the edges of the boot soles, but the rubber plates project beyond the metal
FD77

page_text: plates at all points of their scraping edges. The device is provided with a remov-
able trays fitted to slide in the base m which serves to catch the dirt and moisture
scraped off the boots.
Instead of attaching the scraper to a base, as shewn in the drawings, it may be
fitted in a frame for use instead of the ordinary house-step scraper. By passing
the boot once across the block, it is efficiently cleaned.
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-
A scraper composed of rubber and metal plates set edgewise, combined and
clamped together as described, the acting edges of the rubber plates projecting
beyond the edges of the metal plates and the plates having upwardly-projecting
undercut shoulders near the end, as described.
