the nature of said invention for "IMPROVEMENTS IN MACHINES FOR PLANING THE
EDGES OF METALLIC PLATES to be as follows:-
:―
"
Machines for planing the edges of metallic plates have heretofore been constructed
for planing one edge at a time of one or a series of plates.
Our invention has for object the planing of two edges of one or more plates at
the same time, the additional edge or edges thus planed forming the end of the
plate or plates under treatment.
For this purpose, in addition to the usual bed or slide which carries the movable
slide of one cutting tool, we provide a second bed or slide which is placed at right
angles to the first named one. On the second named bed or slide we mount
a movable slide for carrying another cutting tool.
These movable cutter slides have driving motions independent of each other, and
in order that they may not come into contact on approaching the angle formed by
the first and second named beds, one of the said movable cutter slides has control
over the belt shipping mechanism of the other so that it can reverse its motion in
time for it to recede such a distance as to prevent a collision of the two.
The tool holders usual in this class of machine are of the turn-over kind so as
to enable the machine to plane in both directions; this feature obtains in both the
above-named tool holders. That on the last named bed which operates on the end
of a plate or plates, being required to plane otherwise than at a right angle to that
on the first named bed, has imparted to it a compound motion, one in the direction
of the bed upon which it slides, and a motion transverse thereto by means of
a radial bar or "forme" having command of the tool holder slide, and which is
capable of adjustment either to a right angle or to an obtuse or acute angle in
relation to the longitudinal edge of the plate or plates.
The ends of plates may also be planed to a curvilinear form by means of a suit-
able guide bar or " forme " in connection with the tool-holder slide.

page_text: We, REYNOLD HENRY NEWTON ALLEYNE, and CHARLES SCRIVEN, both of the
Leeds Old Foundry, Leeds in the County of York, 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 :-
Machines for planing the edges of metallic plates have heretofore been constructed
for planing one edge at a time of one or a series of plates.
Our invention has for object the planing of two edges of one or more plates at
the same time, the additional edge or edges thus planed forming the end of the
plate or plates under treatment.
For this purpose, in addition to the usual bed or slide which carries the movable
slide of one cutting tool, we provide a second bed or slide which is placed at right
angles (or thereabout) to the first named one. On the second named bed or slide
is mounted a movable slide for carrying another cutting tool. These movable
cutter slides have driving motions independent of each other, and in order that they
may not come into contact on approaching the angle formed by the first and second
named beds, one of the said cutter slides has control over the belt shipping
mechanism of the other, so that it can reverse its motion in time for it to recede
such a distance as to prevent a collision of the two.
The toolholders usual in this class of machine are of the turnover kind so as to
enable planing to be performed during both the forward and backward movement
of the cutter slide. This feature obtains in both the abovenamed tool holders..
That on the last named bed which operates on the end of a plate or plates being
required to plane at various angles to that on the first named bed, has imparted to
it a compound movement, that is:-a movement in the direction of the bed upon
which it slides, and another transverse thereto, by means of a radial bar or "forme"
having command of said tool holder slide, such radial bar or "forme" being capable
of adjustment either to a right angle or to an obtuse or acute angle in relation to
the longitudinal edge of the plate or plates under treatment.

The ends of plates may also be planed to a curvilinear form by means of a suit-
able guide bar or "forme" in connection with the tool holder slide, such guide bar
or "forme" having a similar shape to that required to be produced on the end of
the plate or plates under treatment.
In the accompanying drawings like letters represent the same parts wherever
they occur. Fig. 1. shews in front elevation a machine for planing the edges of
metallic plates according to our invention as seen looking directly at the bed a.
The means for holding a plate or a series of plates 1, to be operated upon, the
saddle b, and tool holder b 1. are such as employed in machines as heretofore
constructed
Our invention is in the portion illustrated at ② Fig. 1. and is shewn also in
end elevation in Fig. 2. and in general plan in Fig. 3. We provide a bed c, and
saddle d, with tool holder e.

page_text: This bed c, is placed at right angles or thereabout to the bed a, and is suitably
mounted on the uprights c1, and c 2, so as to be above the work under treatment.
Each tool holder has a separate driving motion, the saddle b, being driven in the
usual manner by the pulleys b¹ and screw b 2, while the saddled with its toolholder e,
is driven by the pulleys e 1. shaft e 2. gearing e 3, and the screw e 4, but in order that
the two saddles b, and d, may not come into contact with each other at the junction
or angle formed by the beds a, and c, the belt shipping apparatus having command
of the saddle d, is under the control of the saddle b, as follows:-As the saddle b,
approaches the point: C②CC:: :: : corner formed by the two beds a, and c, the bowl or
tappet b 3, (on the saddle b) comes in contact with the inclined part f, of the
lever f¹, mounted upon the shaft f2, which is free to turn in the bearings f3-ƒ4,
and is thus caused to make an angular movement.
On the said shaft f2, is mouted the lever g. having connected thereto the rod h,
to which is imparted a downward movement.
The top part of the rod h, is connected to the lever i, whose fulcrum is at i 1, the
opposite end of this lever is connected by a link j, to the lever k, which is mounted
and free to turn in the bearing / 1,-k 2 is a collar on the boss of the lever k, and
prevents its end wise motion in the said bearing, k 3, is a lever having a boss or
sleeve that passes through and is capable of sliding endwise in the boss of the
lever k, to which it is connected by a groove and feather so as to partake of
the angular motion thereof, the object being that when the saddle b, approaches
the angle formed by the two beds a, and c, the mechanism just referred to, which
is actuated by the motion of such saddle shall have the effect of placing the end of
the lever k 3, in the same plane as the tappet l, on the saddle d, thus during its
motion actuating the shipping apparatus of the driving belt of the last named
saddle and reversing its motion.
This apparatus consists of a rod m. (having a bearing at one end in the boss or
sleeve of the lever k 3. and at the other end in the carriage n) a forked part o fixed
to the rod m, link p, bellcrank q, link r, sliding bar s, and forks t, u.
v, is a hand
lever in connection with the the rod m, used for starting and stopping the machine
and capable of being locked in a central or neutral position, it is weighted at its
upper end to assist in completing the belt shipping in either direction.
To provide for the contingency of the saddle d, being so far advanced towards
the junction of the beds a, and c, so that the tappet , will not permit of the
lever 3, being moved into the plane thereof, a tappet m 1, is placed on the rod m,
which is actuated by the part d 1, of the saddle d, (and to permit of the saddle b,
in the meantime actuating a part of the belt shipping mechanism of the saddle'd,
the rod h, is constructed with a yielding part at h 1,) m 2 is a tappet on the rod m,
by which the belt shipper is moved in the contrary direction.
The tool holder e, has a horizontal sliding movement in the saddle d, this is
controlled by the radial or guiding "forme" w, which is capable of adjustment
horizontally so that the end or ends of a plate or plates under treatment may be
planed either at a right, an obtuse or an acute angle with its or their side or sides.
When it is required to curve a plate or plates at the end or ends thereof the radial
or guiding "forme " w, is replaced by one having the desired curve whether concave
or convex.
The machine will admit any length of plate or plates.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1. Adapting a plate edge planing machine to plane a plate or set of plates simul-
taneously at two edges situate at or approximately at right angles to one another
