PROVIDIUNAL DITUIFICATION.
Improvements in connection with Sawing, Planing and similarly
operating Machines.
I, EDWARD KAVANAGHI, 1, Shannon Street, Limerick, Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to improvements in connection with sawing, planing and
similarly operating machines and the object is to provide means whereby may
be ascertained the number of lineal and superficial feet of material passed through
the machine. I shall for the purpose of this specification assume the invention
to be applied to a circular saw bench without however confining it solely to that
one use as it is applicable to planing machines, deal and log frames, rack benches,
tonguing, grooving and any similarly working machines. On or near the fence
of the bench and preferably at the saw end thereof I provide a spring or other
contrivance by which is pressed against the timber the periphery of a friction
or toothed wheel. As the timber is moved along the friction will rotate the
wheel and its spindle and the spindle in turn operates a train of wheels con-
tained in a box which also supports the spindle of the friction wheel. In order
that the train of wheels shall indicate the number of superficial feet according
to the width of material cut or operated on, the spindles are made removable and
each furnished with a friction or toothed wheel of different diameter, the
length of the spindles and the diameter of the wheels varying according to the
width of material being operated on. The box is provided with a suitable cover
and face and protected by any suitable kind of guard. The train of wheels is
so arranged that the various friction wheels will cause it to indicate either lineal
feet or superficial feet by hands on a suitably graduated dial according to the
diameter of the particular friction wheel in use at the time.

My invention relates to improvements in connection with sawing, planing and
similarly operating machines and the object is to provide means whereby may
be ascertained the number of lineal or superficial feet of material operated on
For the purposes of this specification I shall assume the invention to be applied
to a circular saw bench without however confining it solely to that one use, as it
is applicable to planing machines, deal-and log frames, rack benches, tongueing,
grooving and any similarly working machines. In putting my invention into
practice I proceed in or in about the following manner making reference to
the accompanying drawings which relates to its application to a saw bench. Fig. 1
is a cross section of the material and a longitudinal section of the recorder.
Fig. 2 is a front view of the dial. Fig. shows how the recorder is attached
to the fence. Attached to one end of the fence 'a of the bench I provide a
spring c to which is attached the case d containing the recording
mechanism to be hereafter explained. The spring C tends to keep
the case d pressed against the material e which is being cut. The
d contains a train of wheels set in motion by the rotation
of a wheel which rotation is brought about by contact with the material e
as it is pushed against the saw. Any suitable train of wheels can be employed
but I instance the following as being very convenient. Suitably supported in
the casing d is the spindle or axle y having at one end the wheel. f already
referred to. On the spindle g is a worm h which rotates the worm wheel i of
60 teeth, on the spindle j on which spindle is the pinion having six teeth,
which gear into the wheel of 40 teeth carried by the spindle m. On the axle of
wheel is a pinion n having six teeth and gearing into wheel o of 54 teeth
carried by spindle p which in turn carries the pinion 4 of 12 teeth. The pinion q
gears into the wheel r of 40 teeth which carries on an axis coincident with its
own the pinion s of 12 teeth. The pinion s gears into the wheel t of 30 teeth
which with the pinion u of 8 teeth is carried on the pipe free to run round
the prolonged spindle p and also carrying the dial hand w. A dial hand x is
also carried by the prolonged end of p. The pinion gears into the wheel y
of 48 teeth having a spindle or axle carrying the dial hand A. The hand
indicates superficial feet from 0 to 450, the hand w shows superficial feet from
450 to 4500 and the hand A indicates superficial feet from 4500 to 27000. It
will be seen that the appliance as so far explained will only measure the super-
ficial feet cut as regards stuff shown by B that to say three inches deep. To
provide for other depths such as seven, nine & eleven inches I proceed as
follows: I prolong the spindle g and furnish it with a wheel C gearing into a
wheel D of twice the diameter of C and carried at the upper end of a spindle E
which is prolonged upwards as at F. To run in contact with material of various
depths I provide wheels G, G1, G2 each carried on its own spindle H having a
socket J to fit over the part F. The circumference of the wheels f, G, G1, G2 are
arranged according to the depth of the material to be cut. For instance the
wheel for 3" stuff is 6" circumference. The wheel G for 7" stuff is 5" 1429 in
circumference. The wheel G¹ for 9" stuff is 5" circumference, and the wheel G³
for 11" stuff is 3" 33 in circumference. Of course only the particular wheel
suited to the depth of material under treatment is used at the time. When all
the wheels G, G and G2 are off the wheel f is in contact with the material and
when any one of the other wheels is on the spindle E, the wheel f is moved out of
contact with the material. The hands of the clockwork move over the dial K
suitably graduated and the dial may be glazed or otherwise protected. Other
arrangements of wheels and graduations of dials and certain modifications in
details to adapt the invention to other machines than saw benches and for show-
ing lineal instead of superficial feet may be made as circumstances may require
and for the spring c any other means such as a jointed arm may be employed to
keep the recorder in contact with the material.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The combination with sawing, planing and similarly operating machines
of a recorder for registering the number of lineal or superficial feet operated
on by the machine, substantially as described in the above specification and
exemplified by the accompanying drawings.
2. The combination with sawing planing and similarly operating machines and
for the purposes of recording the number of lineal or superficial feet operated on
by the machine of a train of wheels operating hands moveable over suitably
graduated dials, the said train being operated by the rotation of a toothed or
other wheel or by several such wheels held in contact with the material by a
spring or other means, the whole substantially as described in the above specifica-
tion and exemplified by the accompanying drawings.
3. In combinations such as are the subject matter of the preceding claims the
use of changeable contact wheels of various circumferences so that the same train
of wheels may serve for making records with reference to material of different
widths or depths, the whole substantially as described in the above specification
anil exemplified by the accompanying drawings.
4. For recording the number of lineal or superficial feet of material operated
on by sawing planing and similarly operating machines a train of wheels and
other arrangements substantially as described in the above specification and
exemplified by the accompanying drawings.
