PROVISIONAL SPECIFICATION.
Improvements in Machines for Planing Metal.
We, CHARLES RISBEE JORNS, of Altrincham, Cheshire, Engineer, and GEORGE
RICHARDS AND COMPANY LIMITED, of Broadheath, Cheshire, Engineers do
hereby declare the nature of this invention to be as follows:-
Our invention relates to that class of planing machines which has an open side
and an overhanging arm carrying the cutting tool, which arm is moved while the
work is held stationary, commonly known as side planing machines.
The improvements have for their object to make the machine more convenient
to work, and stronger and more efficient.
:
One part of the improvement is to combine two side planing machines by placing
them opposite to each other, and parallel, and with their arms pointing inwards,
and with sufficient distance between them for the workman to operate. Tables to
hold the work, capable of being adjusted and swivelled are arranged so that while
one piece of work is being cut in one machine, another piece is being set in the
other machine.
This combination is particularly suitable for planing or scarfing plates for
shipbuilding, boilers & other purposes.
Another part of the improvement is to increase the thrust bearing surface of the
driving screw by making several parallel grooves in it and fitting them with blocks
of suitable metal, capable of being adjusted to take up wear.
Another part of the improvement is a device to regulate the feed, or to reverse
the machine automatically.
We
arrange a bar to slide upon another bar which is fixed and supported by a
bracket from the bed. We place two adjustable stops on the sliding bar and two
on the fixed bar, and we adjust them so that when the cutting head comes in contact
with the stops on the sliding bar, and thus reverses the motion, the stops on the
fixed bar act at the same time on a tumbler device, and put on the feed.
Another part of the improvement is a device to start, stop or reverse the
machine by hand in combination with an independent feed. We employ a round
sliding bar having teeth cut on its underside, and we have a hand wheel in front of
the cutting head, connected to the sliding bar by means of a shaft and toothed
wheel. The adjustable stops are toothed and fixed to the toothed bar by means of
a spring catch and lever working into the teeth of the bar so that there is no
danger of the stops slipping.
Another part of the improvement is a device to start, stop or reverse the machine
by hand. We employ a lever with a fulcrum on the bracket carrying the fixed bar,
and connected to the sliding bar so that the attendant can manipulate the machine
independent of the motion of the countershaft.
We also place a locking bolt on the cutting head so that the attendant can lock
the sliding bar from the front of the machine and can thus instantly reduce the
travel of the cutting head to about two inches.
We propose to use the above devices either separately or in combinations of any
two or more of them.

We, CHARLES RISBEE IORNS, of Altrincham, Cheshire, Engineer, and GEORGE
RICHARDS & COMPANY LIMITED, of Broadheath, Cheshire, Engineers 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:-
Our invention relates to that class of planing machines, which has an open side,
and an overhanging arm carrying the cutting tool, which arm is moved while the
work is held stationary, commonly known as side planing machines.
The improvements have for their object to make the machine more convenient to
work, and stronger and more efficient.
One part of the improvement is a device to regulate the feed, or to reverse the
machine automatically. We arrange a bar to slide upon another bar, which is
fixed and supported by a bracket from the bed. We place two adjustable stops on
the sliding bar, and two on the fixed bar, and we adjust them so that when the
cutting head comes in contact with the stops on the sliding bar, and thus reverses
the motion, the stops on the fixed bar act at the same time on a tumbler device,
and put on the feed.
Another part
of the improvement is a device to start, stop, or reverse the
machine by hand in combination with an independent feed. We employ a sliding
bar having teeth cut on its under or upper side, and we have a hand wheel in front
of the cutting head, connected to the sliding bar by means of a shaft and toothed
wheel. The adjustable stops are toothed, and fixed to the toothed bar by means of
a spring catch and lever working into the teeth of the bar, so that there is no
danger of the stops slipping.
Another part of the improvement is a device to start, stop, or reverse the
machine by hand. We employ a lever with a fulcrum on the bracket carrying the
fixed bar, and connected to the sliding bar, so that the attendant can manipulate
the machine independent of the motion of the countershaft. We also place a
locking bolt on the cutting head, so that the attendant can lock the sliding bar
from the 'front of the machine, and can thus instantly reduce the travel of the
cutting head to about two inches.
We propose to use the above devices either separately or in combination of any
two or more of them.
In the accompanying drawings, Sheet I represents duplex side planing machines
arranged for planing or scarfing plates. Fig. 1 illustrates plan, and Fig. 1^ end
elevation of machines.
The plate to be operated upon is fixed to table A, which can be swivelled to any
suitable angle; the planing arms B are then set in motion, and while they are
planing the plate on table A, another plate may be fixed on table 'A', or vice versa.
Fig. 3 illustrates method of swivelling table.
Sheets 2 and 3 illustrate an improvement in starting and stopping the machines
by hand in combination with tumbler feed. Figs. 2 and 2 show a front and
end elevation of machine. Figs. 4 and 44 show details of reversing, and feed
arrangements.
We provide a fixed bar A which is supported at intervals by means of
brackets G from the back of the bed, carrying a sliding bar B, and a feed stop C.
Bar B has on it two sliding stops D D, and is held in position by brackets E E,
which carry the lever F; this lever has a fulcrum on the brackets G, and can be
removed from one bracket to another, so that the attendant can place it on the
bracket most convenient for his work.

page_text: To start the machine, the stops D D are put in position on the bar B to give
the required stroke of machine, so that when bracket H comes in contact with the
stops D D, they will cause the sliding bar B to move forward or backward on
fixed bar A, and so reverse the machine. At the same time, the tumbler I comes
in contact with stop C, which pushes the tumbler I over, and so gives the movement
for the feed. The sliding bar B is also moved backwards and forwards by means
of lever F, and so starts, stops, or reverses the machine by hand.
.
Sheet 4 illustrates another improvement to start, stop or reverse the machine by
hand.
The
Fig. 5 illustrates plan of cutting head, and Fig. 6 front elevation.
sliding bar J has rack teeth cut on it. A hand wheel K is connected to the
bar J by means of shaft L, and rack or toothed wheel M.
The adjustable stops N, Fig. 7, are fixed to the toothed bar by means of a
spring catch O, and lever P. The machine is started by revolving hand wheel K,
and runs until bracket Q comes in contact with stops N N, when the arm is
reversed.
The hand wheel K is revolving when the machine is running, so by holding
the hand wheel stationary, the machine may be instantly stopped or reversed.
We also place a lock bolt R, Fig. 8, on the cutting head, so that the attendant
can lock the sliding bar J from the front of the machine by means of the hand
wheel S, and thus instantly reducing the travel of the cutting head to about two
inches.
Having now particularly described, and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is ;-
1st. A flat sliding bar, stops and lever, for starting, reversing or stopping the
machines, and regulating the feed, substantially as described.
2nd. The combination of a sliding bar with rack teeth cut in, and connected by
pinion and shaft to hand wheel for starting, stopping, or reversing the machines,
substantially as described.
3rd. The combination of a lock-bolt and sliding bar by means of which the
sliding bar can be locked to the cutting head, substantially as described.
4th. The combination of the above described starting, stopping or reversing
arrangements either with the single or duplex side planing machine.
