page_text: I, EDWARD HUGHES, of 67 Derby Road, Kirkdale in the County of Lancaster
Saw-maker do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a simple effective continuous feed for
circular and other saws. Though particularly designed for circular saw benches, it
will also be found applicable for feeding logs to frame sawa.
It consists of a continuous chain, attached to a revolving shaft or drum, passing
along the side or table of the machine with a dog or coupling bar, one end of
which fastens into the end of the plank or log and the other hooks into or engages
with the links of the chain.
In carrying out the invention, I attach to a revolving drum or spindle placed in
a suitable position, preferably at the base of the machine, an endless chain or band,
and carry the same over a series of rolls or supports within a short distance of the
planks or logs, and in a plane parallel thereto. In a circular saw bench this would
be along side of the bench and within a short distance of the top of it, a short iron
dog or coupling bar is provided, one end of which is stuck into the timber, and the
other hooked into a link of the chain. The revolving drum or spindle will be
geared with the driving shaft of the saw, and while it can be thrown out of gear
without stopping the saw, it can only be put in motion at the same time at which
the saw is running.
The planks will be placed on the saw bench, and the dog attached to one end,
and hooked into the chain; this will carry it through to be cut when it is carried
through a certain distance. Another can be placed in position, and coupled to the
chain, and will be in readiness for the saw to act upon it, as soon as the previous
one is cut. The attendant can then remove the cut planks, and arrange a fresh
one on the bench and attach it to the travelling chain. By this means, a
considerable saving in time will be effected over the present intermittent feed,
which requires the attendant to remove the cut pieces, carry the feed rope back to
the other end of the bench, and then place a fresh deal or log in position.

page_text: improved OTION OF Apparatus for Feeding Timber to
Circular or other Saws,
I, EDWARD HUGHES, of 67 Derby Road, Kirkdale, in the County of Lancaster,
Saw-maker, 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:-
The object of this invention is to provide a simple effective continuous feed for
circular saws.
It consists of a continuous chain attached to a revolving shaft or drum, passing
along the side of and outside the table of the machine with a dog or coupling bar,
one end of which fastens into the end of the plank or log, and the other hooks into
or engages with the links of the chain.
In the drawing annexed is shown in
Figure 1 elevation of circular saw bench with my apparatus attached thereto,
and in
Figure 2 front and side view of the dog or coupling bar.
A is a revolving drum on spindle a placed in a suitable position on the outside
of the table of the machine preferably at the base of the machine, as shown. B is
an endless chain or band passed along the side of and altogether outside the table
of the machine and passed around the drum A in such a way as to receive motion
therefrom. It may be placed with one or two turns round the drum, or placed
above it, and held down into it by rollers, but I prefer the arrangement shown. A
is the drum from which the chain receives motion and C carrier rollers over which
the chain passes, and by means of which it is held in contact with the drum A.
The endless chain is carried over a series of rolls or supports D at the side of and a
short distance below the surface of the table of the bench and within a short
distance of the planks or logs, and in a plane parallel thereto. E is a short iron
dog or coupling bar provided with a hook or hooks at each end-one end e is stuck
into the timber, and the other e¹ hooked into a link of the chain. The revolving
drum A or spindle a will be geared with the driving shaft of the and while it
can be thrown out of gear without stopping the saw, it can only be put in motion
at the same time at which the saw is running.
saw,
The planks F will be placed on the saw bench G and the dog E attached at one
end to it and at the other hooked into the chain; this will carry the plank through
to be cut. When the first log or plank is carried through a certain distance, a
second one can be placed in position, and coupled to the chain, and will be in
readiness for the saw to act upon it, as soon as the previous one is cut. The
attendant can then remove the cut planks, and arrange a fresh one on the bench
and attach it to the travelling chain. By this means, a considerable saving in
time will be effected over the present intermittent feed, which requires the
attendant to remove the cut pieces, carry the feed rope back to the other end of
the bench, and then place a fresh deal or log in position.

page_text: Two or three rollers may be placed on the bench to one side of the saw to carry
the planks back again when they have to be cut a second time, but for this I do
not make any claim, and as regards saws other than circular I do not propose
to proceed with the invention described in the provisional nor to make any
claim therefor.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I wish it to be
understood that I do not claim broadly in connection with sawing machines, the
use of an endless travelling feed chain, nor dogs for connecting same with the logs,
as I am aware that an endless chain has been used for the purpose passing along a
groove or cut, on top of the table and down under it inside the framing, but
I declare that what I claim is :-
The use with a circular saw bench of a feed apparatus consisting of an endless
travelling chain or band placed at the outside of and along the side of the table,
driven by a revolving drum or wheel and supported on carrying drums or rollers,
all placed outside of and against the side of the table and having a connecting dog
or bar, substantially as described and shown.
