COMPLETE SPECIFICATION.
Improvements in Mats or Scrapers.
We, HENRY BEISHEIM, of Rochester, in the County of Monroe, State of
New York, and HENRY PATTBERG, of Jersey City, in the County of Hudson,
State of New Jersey, United States of America, Gentleman, and HENRIETTA
PATTBERG, of Jersey City, in the County of Hudson, State of New Jersey, United
States of America, Lady, do hereby declare the nature of our invention for
IMPROVEMENTS IN MATS, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :—
Our present invention relates to that class of mats employed as floor coverings
and door mats composed of strips; preferably of metal, and serving also as scrapers,
to remove mud and snow from the shoes, and it has for its object to provide a mat
that is ornamental, simple in construction, and can be readily made at a less cost
than other mats presenting the same degree of finish and strength, and to these ends
consists in certain improvements in construction and combination of parts all as will
be hereinafter described and the novel features pointed out particularly in the
claims at the end of this Specification.
In the drawings:
Figure 1 is a plan view of a mat constructed in accordance with my invention.
Figure 2 a perspective view of the end of one of the strips showing the manner
of forming the corners when making the frame of a single piece of tubular
material.
Figure 3 a horizontal sectional view.
Figure 4 a section taken on the line y-y of Figure 3.
Figures 5 and 6 views showing the manner of forming the corners when making
the frame of a single piece of tubular material.
Similar letters of reference in the several figures denote similar parts.
In our present construction the mat consists generally of strips of metal A secured
in a frame B, so that their edges may be presented on opposite sides of the latter
forming two scraping surfaces.
The frame B of rectangular form is preferably constructed of tubular material
thereby giving a finished appearance to the mat and also co-operating with the
strips to firmly secure the mat together and the whole may be formed of several
sections B. B¹, constituting the ends, and B2, B3, the sides connected by connecting
corner pieces B³, as shown in Figures 1 and 3, or it may be a single piece, the
corner being formed as in Figures 5 and 6, and further on described.
On the inside of each of the end pieces B₁, B', of the frame are provided slots C
and upon the ends of the strips A are formed heads D about the size of the inside
of said end pieces, the neck a being about the width of the slot C so that when the
heads D are within the end pieces the latter being rigidly held by the sides, the
strips will be incapable of movement longitudinally and as they are in contact with
each other lateral movement will be prevented.
The strips A are preferably corrugated and are so disposed in the frame that the
corrugations of adjacent pairs will abut as shown and as it is desirable that these
strips should be secured together to make the mat solid we form in say every fourth
corrugation on one side of the strip a perforation A' and upon the other side of the
next corrugation we punch out a small tongue A³, said tongues and perforations
being so arranged that when the strips are placed together with the heads held in
the frame, the tongues in one strip will enter the perforations in the next preceding
one and they can be turned down, fastening the whole series together as shown in
Figure 3. It will, of course, be understood that these tongues and perforations,

page_text: can be placed as frequently or as far apart as may be desired, depending upon the
size and purpose for which the mat is used.
For the purpose of securing the end strips to the frame and also of producing a
more finished mat we prefer to construct the sides B2, B2, of the frame of pieces of
tubular material similar to the ends connecting them to the latter by corner
pieces B³. These corner pieces are preferably of a size equal to the diameter of
the frame ends B' having reduced ends adapted to enter the side and end pieces and
to be secured by rivets b, b, passing through them as shown.
The end strips E, G, are provided with heads D similar to the other strips and
strip E, with perforations A¹ for the accommodation of the tongue on the next
strip A and in lieu of the tongue A², we secure small plates E to the strip as
shown in Figure 4. These plates consist of a head corresponding to the inside of
the frame portion B2, and a narrow portion which is passed through the strip and
upset, firmly securing the plates to the strip, and these plates may be so disposed
in the length of the strip as to correspond to the tongues A2 or may be located at
any number of points as may be desired.
The strip G on the other side of the mat corresponding to strip E is provided
with tongues A2 adapted to enter perforations A in the next preceding strip and
the plates E' are secured to it in place of the perforations A¹ so as to have all the
strips A intermediate the sides, uniform, as will be understood.
In mats formed in the described manner it will be seen that not only are the strips
all held together by a simple form of fastening dispensing with the use of rivets
which it would be difficult to properly place and upset in proper position, but also
that the mat is secured to the frame in a manner that makes the whole a very solid
structure not liable to become loose or shaky when subjected to hard usage and it
is further strengthened when galvanized which will serve to solder the parts firmly
together, but this treatment is not as necessary as in some form of mats, though it is
desirable.
In making the mat we prefer to proceed as follows: The end strip E having the
end strip by thereon is first secured to the side B2 of the frame-by-sliding-the-plates
into the end thereof, then the body of the is formed by placing the strips in
succession against it and securing them to it and to each other by passing the
tongue A through the perforation A' and turning them down as these latter are
situated at a predetermined distance apart, the heads D on the strips will all come
in line. Then the corner pieces B³ are riveted to the side pieces B and the frame
ends B, B, slipped over heads D and the corners B3 riveted to these after which
the other frame side B2 with the strip G connected thereto by plates E', is placed
in position the tongues being entered in corresponding apertures A' and turned
down. Then-the-other-two-corner-pieces-B³-are-riveted to the-frame sections and
the mat is completed ready for galvanizing if this is to be done.
Any other way of assembling the mat may be pursued but we prefer this.
Instead of forming the frame B of separate sections we propose in some instances
to form the frame of a single piece of slotted tubular material bent into proper
rectangular shape.
The bend at the corners is formed by cutting small V-shaped pieces from the
inside of the tube at these points, as in Figure 5 and inserting a plug of material F,
therein to support the walls of the tube when it is bent around into position as shown
in Figure 6 preventing their collapsing. When this form of frame is employed
the two ends and one side of the frame are bent into position and the-heads-D-of-
the strips are inserted in the end pieces B¹. When the outer side is to be formed the
end strip G is secured to the balance of the strips, and the last side bent over, the
plates E, E riveted to the last strip and the corner of the frame secured by a
connecting piece similar to F, riveted to the side and end portions.
While we prefer to connect the end strips E, G, to the frame in the manner
described as the mat is given a more finished appearance thereby, such construction
is not essential but these strips could be secured in any other desired manner as by
rivets passing through the frame.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:

strips secured therein, having the corrugations abutting and co-operating tongues
and perforations formed in said strips for securing them together; substantially
as described.
