IMPROVEMENTS IN APPARATUS FOR CUTTING OR SURFACING WOOD PAVEMENT
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I ARTHUR CHANNING BICKNELL of the Sandycroft Foundry Company Limited
(near Chester) in the County of Flint Engineer do hereby declare the nature of
the invention for IMPROVEMENTS IN APPARATUS FOR CUTTING OR SURFACING
WOOD PAVEMENT to be as follows:-
"
This Invention relates to apparatus adapted to cut or "surface" wood pavement,
already laid, and which may have become uneven from wear or from other causes.
The invention consists of the arrangement and combination of parts hereinafter
described. Upon a suitable frame or truck is placed the boiler or other motive
power generator and connected therewith is a three cylinder or other high speed
engine which by means of suitable shafts, and preferably friction gear, drives one,
or a series of horizontal saws or cutters, vertically adjustable, or if preferred, the
axle boxes of the carrying wheels may be capable of vertical adjustment, the object
being to regulate the amount or depth of cut of the saws or cutters, which remove
the top, or "surface" the blocks, the debris being brushed or collected to the sides
out of the line of travel of the wheels and preferably mechanically carried up and
delivered near the fire hole of the boiler Said boiler or motor also providing the
power for moving the entire apparatus.

I, ARTHUR CHANNING BICKNELL of the Sandycroft Foundry Company Limited
(near Chester) in the County of Flint, Engineer, do hereby declare the nature of my
said invention for IMPROVEMENTS IN APPARATUS FOR CUTTING OR "SURFACING
WOOD PAVEMENT, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
"
This invention relates to apparatus adapted to cut or " surface wood pave-
ment, already laid and which may have become uneven from wear or from other
causes. The invention consists of the arrangement and combination of parts
.”

page_text: hereinafter described. Upon a suitable frame or truck is placed the boiler or other
motive power generator and connected there with is a three cylinder or other high
speed engine which by means of suitable shafts, and preferably friction gear drives
one, or a series of horizontal saws or cutters vertically adjustable or if preferred,
the axle boxes of the carrying wheels may be capable of vertical adjustment, the
object being to regulate the amount or depth of cut of the saws or cutters which
remove the top, or "surface" the blocks, the debris being brushed or collected to
the sides out of the line of travel of the wheels and preferably mechanically carried
up and delivered near the fire hole of the boiler. Said boiler or motor also
providing the power for moving the entire apparatus.
In order that my invention may be fully understood reference is made to the
accompanying drawings which form part of this specification and in which like
letters of reference refer to corresponding parts of the apparatus.
Fig 1 represents a side elevation partially in section.
Fig 2. represents a plan, and
Fig 3. represents an end elevation partially in section.
The frame work A carries motive power generator B and a three cylinder or
other high speed engine O, the shaft a of which drives friction wheels D and
through D D when the latter is in contact therewith-The shaft E carries friction
wheel D and revolving cutter frame F with cutters ff.-Shaft E revolves in
casing G which in turn is eccentrically held in bearings g g in which it can be
turned by means of the lever H by means of which the friction wheel D¹ is thrown
in or out of gear.
Engine shaft "a" carries bevel wheels I. J governed by lever L through which
either wheel may be put into gear with bevel wheel K depending upon whether
it is desired to advance or reverse the direction of travel of the machine-If the
engine is capable of being reversed, bevel wheel J may be omitted.
Shaft K carries worm M which operates the carrying wheels O and gear N which
operates the arm or paddle wheel P which is intended to force the cuttings up the
incline Q to receptacle R.
The axle boxes 8. 8. are vertically adjustable by means of hand wheel S, and by
thus raising or lowering the back of the framework A the depth of cut is regulated
or the cutters raised clear when travelling while the trailing or guiding wheels are
turned by hand wheel T and connected gear.
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:-
In apparatus for cutting or surfacing wood pavement a rotary cutter driven
and regulated substantially as and for the purposes hereinbefore set forth.
Dated this Eleventh day of December 1884.
