Improvements in Joiners' Jobbing Bench or Variety Woodworking
Machine.
JOHN ANDERSON 38 Elswick Row Newcastle-on-Tyne Engineer 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 improvement consists of a circular sawbench with continuous roller feed for
resawing deals and battons also for surface planing jointing and thicknessing and
straight mouldings. I will now proceed to explain my said invention more in detail
reference being had to figures and letters on the accompanying drawings.
Fig. 1 is a side view of the machine showing the working parts of the radial
arm feed.
Fig. 1 is a plan showing special fences set for surface planing.
Fig. III shows radial arm extended for thicknessing. The wood to
the fence K. and the cutters from left to right.
pass between
Fig. IV shows geared feed rollers J attached to fence K. The feed in the
radial arm consists of driving shaft A operating by means of bevel gearing vertical
shaft B. and horizontal shaft C with worm C₁ which turns the roller D being
pressed up to the work by lever E gripping the vertical leg of the radial arm,
within which the vertical shaft B revolves see Fig. V. and having chain and
weight E Fig. I. vertical spindle indicated by line F and driven in the usual
manner used as surface planer as shown in Fig. II. where the radial arm feed
may also be applied, and fences G and G attached to the sawfence K. the
back fence G being adjustable by bevil slides and screw H. Fig. II and VI.
and the whole being adjustable together by the lateral shaft L passing through
the sleeve of fence K and hand wheel with screw L. Removing the fences G and G¹
and extending the arm roller D. behind the cutters as in Fig. III, and the geared
rollers J. Fig. IV and VII driven by lateral shaft M below the table by worm
and wheel operating the rollers through a slot in the table the whole driven by
chain off shaft A. and reversing the motion of the feed rollers for thicknessing and
straight mouldings the wood passing between the cutters and the fence from left
to right. By turning fence K on the shaft off the table the cutter spindle is free
to work circular mouldings, and the head of the spindle being connected to the
main spindle by spigot and socket and secured by a union nut below the face of
the table can be detached and the bench used for cross cutting. When resawing
deals the fence K is brought to the required gauge upon the shaft L and the radial
arm adjusted the deal passes between rollers D and J. the saw being driven in the
usual way.
Having now described and ascertained the nature of my said invention and how
the same is to be performed I declare that what I claim is
First. The combination of a sawbench and single vertical spindle to perform
the various operations specified.
Second. The combined action of feed rollers J and radial arm with roller D,
substantially as shown and for the purpose set forth.
