PROVISIONAL SPECIFICATION.
Machinery for Outting or Splitting Wood into Circular, Oval, or
Angular Pieces or Sections for Firewood and other purposes.
I JOSEPH ROBINSON MAYFIELD of Riplingham, Carlisle Road Eastbourne,
Sussex Paper Manufacturer I do hereby declare the nature of this invention to be
as follows:
The machine consists of a stand or foundation upon which are fixed :-
First. A feeding box or trough in which is placed the wood intended to be
cut or split and which is arranged so that the wood is supplied to the knife or
cutter as required.
Second. Also on the said stand or foundation, slides or grooves are fixed, at
the end of the above named feeding box, in such manner that a frame-called the
knife frame may travel or work forwards and backwards in the said slides or
grooves across the end of the feeding box, the said knife frame being made to work
by any suitable mechanical arrangement.
Also upon
the said knife frame are fixed-
First. A corrugated knife or cutter, the corrugations of which may be such as
to cut or split the wood into pieces either round or oval or angular or of any
shape that may be required and the said knife or cutter may be made of one piece
or may be made up of several sections which may be placed close together or at
any desired distance apart and may be secured by any suitable means either to
the before mentioned knife-frame or may be secured to a separate plate and this
plate may be secured to the knife frame.
Secondly. There is also fixed on the said knife-frame at a convenient distance
from the knife or cutter a receiving or catch-plate upon which the wood which
has been placed in the feeding box in order to its being cut or split-may rest
whilst it is being so cut or split and also to receive or catch the said wood after
cach operation of cutting or splitting and to retain it in position for each succeeding
operation of cutting or splitting.

COMPLETE SPECIFICATION.
Machinery for Cutting or Splitting Wood into Circular, Oval, or
Angular Pieces or Sections for Firewood and other purposes.
I JOSEPH ROBINSON MAYFIELD of Riplingham Carlisle Road Eastbourne
Sussex Paper 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 machine consists of a stand or foundation on which are fixed
First. A feeding box or trough in which is placed the wood intended to be cut
or split and which is arranged so that the wood is supplied to the knife or cutter
as required.
Second. Also on the said stand or foundation slides or grooves are fixed at the
end of the above named feeding box in such manner that a frame called the knife
frame may travel or work forwards and backwards in the said slides or grooves
across the end of the feeding box, the said knife frame being made to work by any
suitable mechanical arrangement.
Also upon the said knife frame are fixed

page_text: First. A corrugated knife or cutter the corrugations of which may be such as
to cut or split the wood into pieces either angular or of any other shape that may
be required and the said knife or cutter may be made of one piece or may be made
up of several sections which may be placed close together or at any desired
distance apart and may be secured by any suitable means to the before mentioned
knife frame or may be secured to a separate plate and this plate may be secured
to the knife frame.
Secondly. There is also fixed on the said knife frame at a convenient distance
from the knife or cutter a receiving or catch plate, which may be made so that it
can be adjusted so as to regulate the thickness of the pieces of wood to be cut or
split off, or this catch plate may be formed by recessing the end of the travelling
knife frame so as to obtain the required thickness of the pieces to be cut or split
off from the block of wood in the feeding trough. The use or purpose of this
catch plate is, that when a block of wood has been placed in the feeding trough in
order to its being cut or split, the said block may rest on the catch plate previous
to its being so cut or split and also when the knife has been withdrawn after each
operation of cutting or splitting, the block of wood may slide down on to the catch
plate so as to be in position for the next operation of cutting or splitting.
In the accompanying drawings-
Fig. 1. represents a section of the machine drawn through the feeding box A—
shewing also the knife frame B and the knife C.
In Fig. 2. the feeding box is shewn at A, the knife frame at B and the knife
at C. The receiving or catch plate is shewn at D being the part included within
the letters a. b. c. d-and may be either an adjustable plate as set forth in the
Specification, or may be part of the knife frame, and in the latter case it would
form a recess in the end of the knife frame as shewn in Fig. 2^, the part a-b
being recessed to form the catch plate which in this case cannot be adjusted to
alter the size of the pieces to be cut or split off.
Fig. 3. shews a plan of the machine.
Fig. 4. is a plan of the corrugated knife or cutter of which the end a-b is the
cutting end and the part a. b. c. d is the corrugated portion, and the part c. d. e. f
is for bolting to the knife frame through the bolt holes shewn by circles in the
drawing. When the knife or cutter is made up of several sections it is preferable to
have at least two bolts to each section as shewn in the drawing but when the knife
is made of one piece a smaller number of bolts than shewn in the drawing would
be sufficient.
Fig. 5. shews a section of the knife drawn through the line a. y. in Fig. 4.
