page_text: Improvements in Saw Benches.
I, ALLEN RANSOME, of Stanley Works, King's Road, Chelsea, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
At the present time two sorts of automatic feed saw benches are made namely
drag feed benches and roller feed benches. The former being most suitable for
large timber and the Intter for boards.
According to this invention I provide the bench with both feeds so that it may
be employed for all sorts of work and I do this in such manner that the one feed
can be readily thrown out of gear and the other put in.
In a well known drag feed, the hook engaging with the rear end of the
timber is fixed to a rope or chain wound up on a barrel driven from the shaft
of a worm wheel gearing with a worm on a shaft driven by a belt from a pulley
on the shaft of the saw or from the countershaft which drives the saw. In such
arrangements I place a double clutch on the shaft of the worm wheel so arranged
that by increly shifting its position on this shaft it can either drive the barrel as
before or another corresponding clutch on a bevil wheel on the horizontal shaft
beneath the bench for working the roller feed. This horizontal shaft drives a
vertical shaft which in its turn drives a horizontal shaft carried by an arm pivotted
ou the top of the bench. This arm has pivotted to it a feed roller or rollers
a vertical spindle driven by bevil gear from the last mentioned
horizontal shaft and pressed against the wood by a cord and weight tending to
turn the arm about its pivot.
When the roller feed is not in use the cord is detached from the arm and the
latter is turned back out of the way.

1, ALLEN RANSOME, of Stauley Works, King's Road, Chelsea, in the County of
0 Middlesex, 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 :-
At the present time two sorts of automatic feed saw benches are made namely
drag feed benches and roller feed benches. The former being most suitable for
6 large timber and the latter for boards

employed for all sorts of work and I do this in such manner that the ouc feed cau
be readily thrown out of gear and the other put in.
In a well known drag feed, the hook engaging with the rear end of the timber is
fixed to a rope or chain wound up on a barrel driven from the shaft of a worm
wheel gearing with a worm on a shaft driven by a belt from a pulley on the shaft
of the saw or from the countershaft which drives the saw. In such arrangements
1 place a double clutch on the shaft of the worn wheel so arranged that by merely
shifting its position on this shaft or by moving the shaft itself longitudinally it can
either drive the barrel as before or another corresponding clutch on a bevel wheel
on the horizontal shaft beneath the bench for working the roller feed. This
horizontal shaft drives a vertical shaft which in its turn drives a horizontal shaft
carried by an arm pivotted on the top of the bench. This arm has pivotted to it a
feed roller or rollers nounted on a vertical spindle driven by bevil gear from the
Just mentioned horizontal shaft and pressed against the wood by a cord and weight
tending to turn the arm about its pivot.
When the roller feed is not in use the cord is detached from the arm and the
latter is turned back out of the way.
Figure 1 in a longitudinal section of the clutch mechanism I prefer to employ.
Figure 2 is a side elevation partly in section of the complete machine and
Figure 3 is a plan of the same part of the bench being broken away. Figure 1 is to
a larger scale than Figures 2 and 3.
a is the bench and at the ordinary fence or guide for the wood. b is the saw bits
shaft, the belt pulley driving it and 63 pulleys on the shaft b' driving by means of
the belt b' pulleys c on the shaft c' of the worm 0. d is a worm wheel gearing with
the worm c. The worm wheel d is provented from moving with the shaft e by bruckets d¹
fixel to the frame. The shaft e is supported in hollow shafts g and j in which
it is free to be moved longitudinally by the clutch lever factuated by the push
and pull handle and engaging with a groove in the block e fixed to the shaft.
Fixed to the shaft e are a pair of clutches e aude. When the shaft e is moved to the
left the clutch engages with the clutch g' at one end of the shaft g at whose other
end is a pinion g³ gearing with a ring of internal teeth in the drum . h is a rope
wound on the druin h passing around pulleys h³ aud having at its end the hook
the drag feed. When the shaft e is moved to the right the clutch e engages with
the clutch at the end of the shaft j whose other end carrics the bevel pinion j
gearing with the bevel pinion on the vertical shaft k which also carries the bevel
pinion gearing with the bevel pinion on the horizontal shaft l. The shaft works
in bearings in the arm m and carries a bevel pinion gearing with the bevel pinion n
on the vertical shaft n to which are fixed the feed rolls n. The arin m is pivotted
on the standard m on the bench a and the rolls are pressed against the wood
by the cord o and weight o'.
of
Having now particularly described and ascertained the nature of any said
invention and in what manner the same is to be perforined I declare that what I
claim is :-
1. The combination of a drag feed, a roller feed, shafts actuating them, clutches on
the shafts and a shaft carrying clutches which can be made to engage with one or
other of the first mentioned clutches.
2. Saw bonches substantially as described and shown in the drawings.
