Improvements in Saw Benches.
1, NORMAN TAILBY, of 76, Summer Row, in the City of Birmingham, Timber
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in saw benches employed for mounting a
circular saw,
and for supporting deals, planks, and like wood, during the operation
of sawing or cutting to the required lengths or sizes.
The object of my invention is to construct a saw bench of few and simple parts
that may be employed either for ripping or cutting with the grain or fibre of the
wood, or for rapidly cross-cutting to any required size, or for cutting at any desired
angle.
In carrying my invention into effect I employ an iron top or table having its
upper surface planed or machined, and fitted with rollers, and mount the same upon
suitable standards. The circular saw is secured on a spindle carried at the upper
end of a rocking or swinging arm or bracket, pivoted at or near the base of the
standard. The saw projects through a suitable slot formed in the top of the
table. A belt or band pulley keyed or secured to the saw spindle, and
receives motion from the counter-shaft beneath the table. The fence consists
of an angle or other bracket which is hinged or pivoted to the table at
right angles to the edge of the saw. The saw is drawn towards the fence
during cross-cutting or like operations by means of suitable levers and linkage,
attached to the rocking or swinging arm or bracket, and operated by foot power, or
by means of the crank plate hereinafter described. The rocking arm, with the
saw carried thereon, is drawn back or away from the fence by means of a spiral or
other spring.
When employing my improved saw bench for ripping or cutting with the grain
or fibre of the wood, I turn back the fence on its hinges, and thus leave the surface
of the bench clear and free from obstruction. In cross-cutting the fence is turned
up into position to form a guide and support for the wood during the cutting
operation. To enable the cross-cutting to be rapidly performed when cutting the
elm or other ends or sides of packing cases, wood paving blocks, or other pieces of
equal length, I preferably feed up the saw by a belt or like driven crank or crank
plate. 1 mount such a crank or crank plate upon a shaft carried at one end of the
bench and driven by a belt, chain, or gearing, from the counter-shaft beneath
the bench or table. I also provide a gap in the surface of the bench or table, or
a gap-piece that may be readily removed, in order that the cross-cut pieces may fall
from the table after cutting to the required length. The length or size of the cross-
cut pieces is fixed by means of an adjustable gauge or stop, secured to the fence.
The movement of the swinging saw arm or bracket in either direction is limited
by means of adjustable block or stop pieces, within a suitable circular or other
guiding frame.
I do not limit the application of my invention to a saw bench of particular
dimensions or for any special service, but make modifications in my improvements
to adapt the same to varying requirements.

I, NORMAN TAILBY, of 76, Sumner Row, in the City of Birmingham, Timber
Merchant, do hereby declare the nature of this invention and in what manuer the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to improvements in saw benches employed for mounting a
circular saw,
and for supporting deals, planks, and like wood, during the operation
of sawing or cutting to the required lengths or sizes.
The object of my invention is to construct a saw bench of few and simple
parts that may be employed either for ripping or cutting with the grain or fibre of
the wood, or for rapidly cross-cutting to any required size, or for cutting at any
desired angle.
In the two accompanying sheets of explanatory drawings to be hereinafter
referred to
Figure 1 is a side elevation and Figure 2 an end elevation representing one
convenient arrangement of my improved saw bench.
Figure 3 is a part plan of the hinged or pivoted fence, while Figures 4 and 5
further illustrate the construction and arrangement of the fence by views taken
respectively from the front and end of the same.
Figure 6 represents a method of adjusting the extent of the reciprocation of the
saw arm or bracket.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect I employ an iron top or table having its
upper surface A (Figures 1 and 2) suitably planed or machined and fitted with
rollers, and mount the same upon a suitable standard or standards. The circular
saw B is secured on a spindle C carried at the upper end of a rocking or swinging
arm or bracket such as D, pivoted at or near the base of the standard or upon the
counter shaft E beneath the floor or base level. The saw projects through a
suitable slot formed in the top of the table in the usual manner, and a belt or
band pulley is keyed or secured to the saw spindle, and receives motion from the
countershaft E by means of the belt F. The fence may consist of an ordinary
angle or other bracket such as G Figures 1 and 2, but I preferably employ a
fence such as illustrated at Figures 3, 4 and 5 to be hinged to the end A' of the
table in any convenient manner, and projecting beyond the side or sides of the
table if required, as shown at Figure 4. The saw is drawn towards the fence
during cross-cutting or like operations by means of suitable levers and linkage,
attached to the rocking or swinging arm or bracket D, and operated by foot
power, or by means of the crank plate hereinafter described. The rocking arm,
with the saw carried thereon, is drawn back or away from the fence by means
of a spiral or other spring or by the return motion produced by the rotation of the
crank plate.
When employing my improved saw-bench for ripping or cutting with the grain
or fibre of the wood, I remove the fence or turn it back on its hinges as shown
by dotted lines at Figure 5, and thus leave the surface of the bench clear and free
from obstruction. In cross-cutting the fence is fixed or turned up into position on
the table to form a guide and support for the wood during the cutting operation.
To enable the cross-cutting to be rapidly performed when cutting the elm or other
ends or sides of packing cases, wood paving blocks, or other pieces of equal length,
I preferably feed up the saw by a belt or like driven crank or crank plate such
as H. I mount such a crank or crank plate H upon a shaft Jcarried at one end of
the bench and driven preferably by the worm and worm wheel receiving motion

page_text: from the countershaft E through the belts K and L arranged in the manner illus-
trated at Figures 1 and 2. I sometimes provide a gap in the surface of the
bench or table, or a gap-piece that may be readily removed, in order that the
crosscut pieces may fall from the table after cutting to the required length.
The length or size of the cross-cut pieces is fixed by means of an adjustable
gauge or stop M, Figures 3, 4 and 5 consisting preferably of an angle plate or
bracket which can be readily clamped to the fence at any required position by
means of the clamping bolt and nut as illustrated. The projecting piece N of the
binged fence bas a slot formed through it to permit of the required adjustment of
the clamping bolt. I sometimes mark or divide a scale or attach a measuring rule
upon the upper face of the hinged fence, as at O Figure 3, in order that the
gauge or stop M may be readily set for cutting pieces of a definite length or
measurement.
I preferably carry the countershaft E by means of the sling arms or brackets P P,
Figures 1 and 2, secured to the underframe or standard of the machine, and I
transmit the required power to the shaft by means of the belt Q from a line shafting
or direct from a steam, gas, or other motive power engine.
To provide for the adjustment of the stroke or travel of the rocking or swinging
arm or bracket D, 1 form holes such as R R R2 in the crank plate, as shown in
the detail view Figure 6, at varying distances from the centre and of such diameter
as to receive the crank pin. Such holes in conjunction with the corresponding
holes S S S in the connecting rod permit of ready alteration of the throw of the
crank to increase or decrease the movement of the rocking arm D, and at the same
time ensure that the saw shall be caused to travel right up to the fence whatever
may be the extent of such movement.
I do not limit the application of my invention to a saw bench of any particular
design or for any special service, but make modifications in my improvements to
adapt the same to varying requirements.
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. The method of adapting a saw bench for ripping or cutting in the direction of
the grain or fibre, and for cross-cutting and like operations substantially as herein
described.
2. In saw-benches, the use of a rocking or swinging arm or bracket for carrying
or supporting the saw spindle and arranged to be reciprocated for cross cutting and
like operations by means of gearing arranged substantially as hereinbefore described
and as illustrated in the accompanying drawings.
3. The construction of a fence or like guide or support to be hinged or
pivoted to a saw bench in such a manner that it may be thrown back clear of
the table or brought over into position upon the same substantially as and
for the purposes herein before described and as illustrated in the accompanying
drawings.
4. In saw-benches, the combination of a hinged fence or like guide or support
with an adjustable stop or gauge arranged substantially as and for the purposes
herein before described and as illustrated in the accompanying drawings.
