PROVISIONAL SPECIFICATION.
Improvements in Scraper Mats.
I, BROR IVAR EDVARD MAURITZ OHLSON, of Nassjo, in the County of Smaland,
and Kingdom of Sweden, Bookkeeper, do hereby declare the nature of this inven-
tion to be as follows:-
The present invention relates to a door-mat that can be manufactured very
cheaply owing to the fact that its chief constituent parts are wooden slats obtained
by sawing up the almost worthless strips cut off in edging planks.
In consists of a frame, preferably of sheet metal, having two opposite sides of
grooved section with the grooves facing each other, one or both of the remaining
sides being so united to the corresponding ends of the sides first mentioned (for
instance by means of screws) that they can be readily disconnected and again
fastened. A number of parallel wooden slats are inserted between the two grooves
and rest in the latter, being held at suitable distances from each other by distance
pieces. In case one or more of the slats should break or, wear out, they can be
easily removed and replaced by others by simply disconnecting one of the sides
of the frame, pulling out the defective slats and inserting new ones in their
places. It is evident that the frame may be made of a quadrangular or triangular
shape, the slats in the later case being made of unequal lengths which is also
the case when to the frame is given the form of a trapezium instead of a
parallelogram.
From what has been said it will be easily understood that such door mats are
very simple and inexpensive to make and easy to repair as compared with the
ordinary scraper mats of iron in which all the parts are rigidly secured to each
other, it being impossible to replace damaged parts short of the cost of making
a new mat.
I, BROR IVAR EDVARD MAURITZ OHLSON, of Nassjo, in the County of Smaland,
and Kingdom of Sweden, Bookkeeper, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
The present invention relates to a door-mat that can be manufactured very

page_text: cheaply owing to the fact that its chief constituent parts are wooden slats obtained
by sawing up the almost worthless strips cut off in edging planks.
In the annexed drawing such a door-mat is shown in Figure 1 in a perspective
view, while Figure 2 represents a slat together with a distance piece belonging
to it.
It consists of a frame, preferably of sheet metal, having two opposite sides a
of grooved section with the grooves facing each other, one or both of the remaining
sides being so united to the corresponding ends of the sides a (for instance by
means of screws) that they can be readily disconnected and again fastened. A
number of parallel wooden slats c are inserted between the two grooves a and rest
in the latter, being held at suitable distances from each other by distance pieces d.
In case one or more of the slats should break or wear out, they can be easily
removed and replaced by others by simply disconnecting one of the sides b of the
frame, pulling out the defective slats and inserting new ones in their places. It
is evident that the frame may be preferably made of a quadrangular or triangular
shape, the slats in the later case being made of unequal lengths which is also
the case when to the frame is given the form of a trapezium instead of a
parallelogram.
From what has been said it will be easily understood that such door-mats are
very simple and inexpensive to make and easy to repair as compared with the
ordinary scraper-mats of iron in which all the parts are rigidly secured to each
other, it being impossible to replace damaged parts short of the cost of making
a new mat.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim_is:-
An improved scraper-mat, consisting of a preferably quadrangular or triangular
frame with two opposite sides (a) of a grooved section with the grooves facing
each other and with two or one of the other sides (b) united with the corresponding
ends of the sides first mentioned in such a manner, that the frame can be easily
opened, this frame embracing a number of parallel wooden slats (c) resting with
their ends in the grooves at suitable distances from each other.
