PROVISIONAL SPECIFICATION.
Improvements in Rebating and Chamfering Machines.
I ALFRED SLATER of Horton Lawn, Gloucester in the County of Gloucester,
Manager to The Gloucester Railway Carriage and Wagon Company Limited
do hereby declare the nature of this invention to be as follows :-
My invention consists of a machine which can be driven by power, for rebating
and chamfering on all edges and at either or both ends of the timber or material to
be rebated or chamfered.
There are the requisite number of headstocks (say two at each end of the
machine) carrying the requisite number of revolving heads or cutters say four at
each end of the machine working in pairs, one pair at each end of the machine
having a travelling motion and the other pair having no travelling, motion. In
each case the cutters or revolving heads can be adjusted, to any required distance
apart to suit the width of the timber or material. The cutters may consist of
blades fixed to revolving heads in the usual manner.
The piece of timber or material to be operated upon having been placed upon
the travelling table of the machine is passed by suitable mechanism such as hand
or power levers or screws through the pairs of stationary cutters, then the pairs of
travelling cutters are set in motion, they travel so as to operate on the remaining
edges of the pieces of timber or material.
Though adapted to operate on all four edges at each end, the machine is adaptable
for cutting any other number of rebates, or for cutting grooves across the timber
or material with or without the rebates and chamfers.
The heads at one end of the machine being fixed those at the other are arranged
so that they can be adjusted to suit the length of the timber or material to be
operated upon.

Improvements in Rebating and Chamfering Machines.
1 ALFRED SLATER of Horton Lawn Gloucester in the County of Gloucester
Manager to The Gloucester Railway Carriage and Wagon Company Limited 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:-
My invention consists of a machine which can be driven by power for rebating
and chamfering on all edges and at either or both ends of the timber or material to
be rebated or chamfered.
There are the requisite number of headstocks (say two at each end of the

page_text: machine) carrying the requisite number of revolving heads or cutters, generally
four at each end of the machine, working in pairs, one pair at each end of the
machine, having a travelling motion, and the other pair having no travelling
motion. In each case the cutters or revolving heads can be adjusted to any
required distance apart to suit the width of the timber or material. The cutters
may consist of blades fixed to revolving heads in the usual manner.
The piece of timber or material to be operated upon, having been placed upon
the travelling table of the machine is passed by suitable mechanism such as hand
or power levers or screws through the pairs of stationary cutters, then the pairs of
travelling cutters are set in motion, they travel so as to operate on the remaining
edges of the pieces of timber or material. Though adapted to operate on all four
edges at each end, the machine is adaptable for cutting any other number of rebates,
or for cutting grooves across the timber or material with or without the rebates
and chamfers. The heads at one end of the machine may be fixed and those at
other end be arranged so that they can be adjusted to suit the length of the timber
or material to be operated upon.
The accompanying drawing illustrates a machine constructed in accordance with
this invention, Figure 1 being a front elevation, Figure 2 a sectional end elevation
and Figure 3 a plan.
A is a travelling table on which the timber or material to be operated upon is
placed and held by means of the hand wheels and screws b and clamping plates a.
The table A can be traversed automatically by the gear B shown in Figure 3, or
by hand by the handle c.
At each end of the table A are standards C and D upon which traverse the
headstocks d and e, carrying respectively the revolving cutters E and F. The
front cutters E have no traverse, but are capable of vertical adjustment by means
of the hand wheels and screws G, and the back cutters F are adjustable by the hand
wheels, and are also provided with an automatic traverse in a vertical direction
by means of the countershaft g, and bevel wheels and screw h, the whole being
arranged to allow for the standards C C and D D, being adjusted to any required
position on their bed plates.
The traversing motions B and g, are provided with open and crossed belts for
reversing the traverse, as shown in Figure 3.
The back cutters F, the table traversing gear B and also the back cutters
traverse gears h, are driven from the countershaft H, a single belt k driving the
back cutters F, it passing over a suitable belt tightening jockey pulley J,
round the pulleys 11 on the cutter spindles.
and
The front cutters E, are driven by a separate belt from a separate countershaft
not shown in the drawing.
The timber or other material to be operated upon being fixed in position on the
traversing table A, the traversing gear B is set in motion and the timber or
material is carried between the front cutters E, its stroke being regulated by the
adjustable stops n. The front cutters E operating upon the top and bottom edges.
As soon as the table A, touches the stops n, the back cutters are set in motion and
as they move in a vertical direction they operate upon the two remaining edges of
the timber or material and the work is finished.
Though adapted to operate on all four edges at each end; the machine is adapt-
able for cutting any other number of rebates or chamfers, or for cutting grooves
across the timber or material with or without rebates and chamfers.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare. that what I
claim is :-
1. In rebating and chamfering machines the combination of headstocks and
adjustable revolving heads or cutters arranged relatively to a support for the
timber or material to be operated upon all substantially as hereinbefore described.

page_text: 2. The arrangement and combination of parts constituting the rebating and
chamfering machine substantially as hereinbefore described and shewn in the
accompanying drawings.
