I, HENRY CONRADI, of 7, Lower James Street, Golden Square, in the
County of Middlesex, do hereby declare the nature of the said Invention
"IMPROVED MACHINE FOR COMPRESSING AND PREPARING PEAT AND OTHER
SIMILAR SUBSTANCES," to be as follows
for a
-
All the less important parts of the machinery who do not constituto
the essential features of my Invention and improvements (as for instance,
the framing or pillars, bearings, cutting-off apparatus, mouth-pieces if
any. and so on), will be fully described in the Complete Specification,
while in thus Provisional Specification I wish to explain and to describe
the different mechanical arrangements which constitute the principle of
my Invention and improvements, and also the manner in which they do
the work. At A and B, Fig 1, are shown two cogged rollers, which
may be of any dimension chosen suitable for producing the effect
required, and the motive power at disposal The cogs of these rollers do
not extend unbroken throughout the entire length of cach, but are

page_text: provided with grooves, and the position of the rollers is such that the
projecting portions of the cogs of one roller clear themselves in the
annular grooves of the other, while the gearing of the roller is so
arranged as to give them different speeds, that is to say, onc revolves,
perhaps two, three, or more times faster than the other (roller A may
have a greater speed than roller B), thus producing an action similar to
that of scissors, the projecting parts of the cogs of the rollers passing
close to each, side by side, though in opposite direction, these cutting
rollers may therefore be called "rotating scissors

"
The application, arrangement, and action produced by such rollers for
cutting up masses of peat as preliminary operation are other main
features of my improved machine To keep the cogs of the rollers clear
I make use of an arrangement which I call a scraping apparatus,” and
which is another essential part of my Invention. its arrangement is as
follows: Below the top rollers A & B are placed two leading rollers
C & D, so that the endless chain α, α₁, a₁, a₁₁, &c., revolving in the
grooves of the upper rollers are guided over the lower ones, preserving a
uniform speed with those of the upper rollers, the motion being secured
by gearing outside one frame or pillars. The bars b, b₁, b₁, &c., are
fastened transversely to these chains at a distance apart equal to the
pitch of the cogs on the rollers A & B, while in revolving the cogs or
teeth of the upper rollers, shaped to an evolvent curve, are continually
grazing the bars of the chain at the moment when the motion of the
latter changes from circular to vertical without however taking any peat
out of the channel in which the peat is pressed. This channel is formed
by the pillars or any frame plates F & G, as shown, containing the
arrangement of bars and chains above described, and allowing of their
free working, the chamber is terminated by the channel E.
The above described scraping apparatus also serves to propel the
masses of peat in the channel, and as the one side is moving faster than
the other it mixes the chopped up peat, giving it at the same time a
revolving motion. By altering the distance between the bearings of the
lower rollers the pressing chamber can be enlarged or narrowed so as to
expose the enclosed material to a greater or less pressure, as may be
required. In the same way the bearings of the top rollers may bo
brought nearer together or set wider apart, so as to obtain a finer or
coarser cut.

page_text: The materials employed in the construction of the machine are those
generally used in machinery for that purpose; I have therefore to point
out as the main features of my Invention the arrangement and form of
the rollers and their cogs, the arrangement of the rollers with respect to
each other and their reciprocal action as rotating scissors, the arrange-
ment of the endless chain with the combination form, and fitting up
of the transverse bars attached to it, forming the scraping apparatus,
and at the same time serving as choppers, mowers, and propellors.
