I, THOMAS NIELD ROBINSON of the Firm of Thomas Robinson and Son, Limited, of
Railway Works Rochdale in the County of Lancaster, Machine Maker, do hereby
declare the nature of said Invention for IMPROVEMENTS IN CROSS CUT SAW BENCHES to
be as follows:-
.
My improved Saw Bench is of the type known as a pendulum cross cut Saw Bench
in which the pendulum arm which carries the saw spindle and saw is pivotted below
the bench and preferably below the floor line to brackets bolted to the Bench. In
place of the saw spindle being below the level of the top of the bench as now customary
the upper part of the pendulum arm according to my Invention projects through and
the saw spindle stands above the level of the top of the bench.
To any convenient part of the pendulum arm is secured a lever connected by a rod
or arm to a pivotted treadle lever by which treadle the saw may be brought up to its
work, and a spring or weight may be employed to draw the saw back to its normal
position when the treadle is released.
On the bench top is mounted an inclined fence set with its upper edge toward the
centre of the pendulum arm; when cross cutting deals the deals are preferably laid on
edge against the fence so that the saw has the shortest distance to travel in passing
through the timber, in this manner the amount of work accomplished by the bench is
greatly increased.
Fast and loose pulleys are mounted on the shaft to which the pendulum arm is
pivotted as usual.

1 THOMAS NIELD ROBINSON of the firm of Thomas Robinson and Son Limited of
Railway Works Rochdale in the County of Lancaster Machine 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:
My improved saw bench is of the type known as a pendulum cross cut saw bench
in which the pendulum arm which carries the saw spindle and saw is pivoted
below the bench and preferably below the floor line to brackets bolted to the
bench.
In place of the saw spindle being below the level of the top of the bench as
now customary the upper part of the pendulum arm according to my Invention
projects through and the saw spindle stands above the level of the top of the
bench,
To any convenient part of the pendulum arm is secured a lever connected by a rod
or arm to a pivoted treadle lever by which treadle the saw may be brought up to its
work and a spring or weight may be employed to draw the saw back to its normal
position when the treadle is released.
On the bench top is mounted an inclined fence set with its upper edge toward the
centre of the pendulum arm; when cross cutting deals the deals are preferably laid on
edge against the fence so that the saw has the shortest distance to travel in passing
through the timber in this manner the amount of work accomplished by the bench is
greatly increased.
Fast and loose pulleys are mounted on the shaft to which the pendulum arm is
pivoted as usual.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being had to the
figures and letters marked thereon.
Figure 1 is a front elevation and Fig. 2 a side elevation of a pendulum cross cut saw
bench embodying my Improvements.
In these views. a represents the upper frame of the bench and 6 the brackets secured
to the under side of the frame a; c is the pendulum arm which is pivoted on the shaft d
and carries at the other end the spindle et on which is secured the saw e. The shaft d
is journaled in the brackets 6 and on it is mounted a fast pulley d¹ and a pair of fast
and loose pulleys f which are driven by a belt operated by the strap fork
and starting
handle. The fast pulley d¹ transmits motion by a band i to a pulley e fixed on the
saw spindle e¹ and the saw e is traversed forward to the timber; by depressing the
front end of a treadle k which is fulcrumed on a short shaft k' which is connected
by an arm k³ and link k³ to the pendulum arm c. The back end of the treadle k carries a
weight m which draws back the saw e as soon as the foot of the attendant is taken off
the treadle.

page_text: The timber is supported on the inclined fence n which is secured adjustably and
obliquely on the top of the bench as shown whereby the saw has the shortest distance
to travel in cutting through the timber as previously mentioned.
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 a pendulum cross cut saw bench in which the pendulum arm which carries the
saw spindle is pivoted below the saw bench I claim mounting said pendulum arm in
such manner that its upper part projects through and the saw spindle stands above the
level of the top of the saw bench.
2. The construction combination and arrangement of parts embodying my improve-
ments in cross cut saw benches substantially as herein described and as illustrated by
the Drawings annexed.
