PROVISIONAL SPECIFICATION.
Improvements in Wood-outting Machinery.
THOMAS GEORGE STEVENS 5 Cobham Terrace Greenhithe, Kent, Engineer,
do hereby declare the nature of this invention to be as follows :-
1
It consists of a self-feeding apparatus, which can be mounted on any ordinary
table or bench; such as circular-saw benches, moulding machines, or the like.
The apparatus is mounted on brackets, to which are fitted bearings. These
bearings carry a spindle. On this spindle are fitted suitable shaped pieces of metal
or wood, which revolve: & so carry the material over the cutters or saws at any
regulated speed. This spindle, which carries feeders, I make to rise & fall, so
that any sized piece of material can be carried over the cutters or saws. This
invention will be found very useful for crozing the ends of staves in coopering.
Dated this 6th day of March 1895.
I, THOMAS GEORGE STEVENS, of 5 Cobham Terrace, Greenhithe, Kent,
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 :-
It consists of a self feeding apparatus which can be mounted on any ordinary
table or bench; such as circular saw benches, moulding machines, or the like. The
apparatus is mounted on brackets, to which are fitted bearings. These bearinga
carry a spindle. On this spindle are fitted suitable shaped pieces of metal or wood,
which revolve, and so carry the material over the cutters or saws, at any regulated
speed.
The annexed drawing shews a machine in accordance with my invention.
Figure 1 is a front elevation, Figure 2 is an end elevation, and Figure 3 is a
transverse section of a machine in accordance with my invention.
Figure 4 is a plan of the table with the operative parts removed.
a a are brackets mounted upon the table, they carry a spindle b. The pieces of
wood or metal c, are fixed upon the spindle b, they are in fact spring arms, serving
as the spindle rovolves, to push the work forward, whilst the cutters operate upon
its under side.
The spindle bas upon it a toothed wheel d, and this is engaged and driven at
a suitable speed by a pinion e on an axis f. The axisƒhas a belt pulley upon it,
which receives a driving belt.
9, is another spindle, it is beneath the work, and on it are fixed the discs or tool
holders, hh for receiving the cutting tools. The machine as arranged in the
drawings is adapted for crozing or cross grooving the staves of casks. The spindle g,.
is driven at a high speed by a belt passing around the pulley i. In order to admit
of adjustment for the depth to which the tools penetrate, the bearings j, in which
the spindle g is carried, are arranged to move vertically in guide slots, in the frame..

page_text: The bearings at each end of the spindle are connected by rods k, to arms upon a
rock shaft, and this shaft also has an arm m upon it to which the rod n is jointed,
o is a hand wheel mounted upon the table, it is fixed upon the upper end of the
rod n and there is a screw joint or coupling in the length of the rod as indicated by
the drawing. Hence by turning, the hand wheel, the rod n, is lengthened or
shortened, and so the cutters may be set to penetrate more or less deeply. pp, are
stationary guides or fences upon the table, the distance between them corresponds
with the length of the staves. 77, are levers, which resting on the staves hold
them down to the table with a pressure sufficient to counteract any tendency of the
cutters to lift them, but nevertheless the levers 9, allow the staves to be driven
forward by the spring arms o. The levers 99 turn about pivots at 9'9' and bear
by their own weight upon the work. Where the work is liable to vary in thickness
the bearings for the spindle b, are arranged to be adjustable to and from the table,
but for work of approximately uniform thickness this is not required.
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 wood cutting machinery, a self feeding apparatus, in which the work is
carried forward over the cutters, by a spindle mounted above the work and driven
at a suitable speed, and having arms fixed upon it as herein set forth.
2. In wood cutting machinery a self feeding apparatus, substantially as described
and illustrated by the annexed drawings.
