1, HEINRICH FREESE, of 54B Kochstrasse, Berlin in the Empire of Germany,
Architect, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to improvements in wood pavements and has for its object
to facilitate a more ready and better fixing of the blocks than heretofore has been
the case.
This consists in forming the wood blocks used for paving, with holes, and
connecting the same to each other by means of spikes, rails, pins, wires or dowels,
to form plates of suitable size.
The plates of wood blocks are on their sides formed tooth-like so as to bind the
separate plates firmly together.

page_text: I, HEINRICH FREESE of Berlin in the Empire of Germany, Architect, 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 improvements in wood pavements and has for its object
to facilitate a more ready and better fixing of the blocks than heretofore has been
the case.
This consists in forming the wood blocks used for paving, with holes, and connecting
the same to each other by means of spikes, rails, pins, wires or, dowels, to form plates
of suitable size.
These plates of wood blocks are on their sides formed tooth-like so as to bind
the separate plates firmly together.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts throughout the various figures.
Figs. 1 & 2 show two paving plates formed of wood blocks threaded together.
Fig. 1 shows such plate formed with straight sides, and Fig. 2, with two opposite
sides, tooth-like.
The threading of these wood blocks is effected by forming each one cross-wise,
with two holes, see Fig. 4, and by passing alternately each end of the wire thread,
respectively, through the holes of one block and then through one hole of two blocks
respectively, as shown in Figs. 8 & 9.
It will be understood that the order of threading these wood blocks may be
reversed, i.e. first two blocks and then one block. The holes through which the wire
thread is passed are made as small as possible in diameter, so as to maintain the
strength of the blocks and prevent the same from splitting.
When a sufficient number of blocks have been threaded onto the wire, the ends of
the latter are twisted, and thereby the blocks secured together, so as to form a paving
plate, as shown in Figs. 1. 2. 3 and 9.
To prevent the wire threads from projecting from the first row of blocks forming a
plate, the same are formed with a horizontal groove a see Fig. 5, and the block of the
last row with a horizontal and a vertical, groove a¹ & B, see Fig. 6, into which the
ends of the wire thread are pressed.
The setting of the paving plates formed of wood blocks may be done in three
different ways; by placing the straight side against, or when toothed in each other,
or as shown in Fig. 7, against each other, in which case alternate openings are formed
which are filled up by what are called filling blocks x. (Fig. 7.)
The object of these openings and filling blocks z, is to bind the paving plates when
in position, tightly together, which is effected by forcing the filling blocks tightly into
the respective openings.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim, is :-
1st. Forming plates of wood blocks, for paving purposes, by threading and
connecting thereby a suitable number of wood blocks formed with holes (Fig. 4) on
wire threads or their equivalents (Fig. 3) in the manner and substantially as described
and shown in Figs. 8 & 9.
2nd. Setting paving plates formed of wood blocks and with tooth-like sides, by
placing such plates tooth against tooth in position, and inserting into the openings
thus formed respectively, separate blocks a, Fig. 7, which serve to fasten the said
plates together, substantially as set forth.
