PROVISIONAL SPECIFICATION.
Improvements in Planing and Moulding Machines.
I, THOMAS NIELD ROBINSON, of the firm of Thomas Robinson and Son Limited',
of Railway Works, Rochdale, in the County of Lancaster, Machine Makers, do
hereby declare the nature of this invention to be as follows:-
My invention relates to planing and moulding machines with four cutter blocks
and the objects of my invention are to improve the driving mechanism and to make
the machine narrower and more convenient than usual.
In carrying my invention into effect I employ the usual countershaft and an
additional countershaft driven say from the first countershaft and I propose to
drive the bottom cutter block and the two side cutter blocks from the usual
countershaft and the upper cutter block and the feed motion from the additional
countershaft.
By this arrangement both the upper and lower cutter blocks can be driven by
open belts and the slack side of the belts being uppermost a higher speed can be
given to these cutters without increasing the stress on the bearings and I further
ensure very steady driving: another advantage is that the spindles of the side
cutter blocks can be made shorter than has hitherto been practicable.

COMPLETE SPECIFICATION.
Improvements in Planing and Moulding Machines.
I, THOMAS NIELD ROBINSON, of the firm of Thomas Robinson and Son Limited,
of Railway Works, Rochdale, in the County of Lancaster, Machine Makers, 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 relates to planing and moulding machines with four cutter blocks
and the objects of my invention are to improve the driving mechanism and to make
the machine narrower and more convenient than usual.
In carrying my invention into effect I employ the usual countershaft and an
additional countershaft driven say from the first countershaft and I propose to
drive the bottom cutter block and the two side cutter blocks from the usual
countershaft and the upper cutter block and the feed motion from the additional
countershaft.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying three sheets of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 represents a side elevation.
Fig. 2 a plan and
Fig. 3 an end view of a planing and moulding machine constructed according to
my invention.
Similar letters refer to similar parts throughout the several views.
In the drawings, a represents the ordinary countershaft, secured to the floor as
usual, a pair of fast and loose pullies a¹ all for the driving belt, (not shown) are
mounted on this shaft. which has also keyed upon it the pulleys b, c, d, e, for
driving the bottom cutter block, the two side cutter blocks, and the additional

page_text: countershaft, which in this case is fitted in bearings secured on the frame of the
machine.
The pulley b by means of a belt b' and pulley 6" drives the spindle fon which
is fixed the bottom cutter block f¹ the pulley e by means of a belt c¹ and pulley c"
drives the spindle g of the side cutter block gf and the pulley d by means of a
belt and pulley d drives the spindle h of the side cutter block /¹.
The additional countershaft j is driven from the shaft a by means of a belt e¹
which passes over pulleys e and i keyed on the shafts a and j respectively. On the
shaft are also keyed a pulley k and cone pulley 1, the former of which drives the
top cutter block m¹ by means of a strap and pulley on the spindle m of the cutter
block m¹.
The cone pulley gives motion by a belt land cone pulley to the feed motion
shaft n from which the feed rollers o o are driven by a train of spur wheels shown
best in Fig. 1; the top feed roller is pressed by weights or springs as usual against
the wood which is being operated upon.
The top cutter block m' and the side blocks ¹ and 9' are mounted in slideways
and the direction of their rotary motion is indicated by arrows.
By the use of my invention both the upper and lower cutter blocks can be driven
by open belts and the slack side of the belts being uppermost a higher speed can be
given to these cutters without increasing the stress on the bearings and I further
ensure very steady driving; another advantage is that the spindles of the side
cutter blocks can be made shorter than has hitherto been practicable.
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 a planing and moulding machine the use of an auxiliary countershaft
which enables both the upper and lower cutter blocks to be driven by open belts.
2. The construction combination and arrangement of parts forming the improved
machine for planing and moulding substantially as described and as illustrated.
