PROVISIONAL SPECIFICATION.
Improvements in Tool Holders for Blotting, Shaping, Planing,
and like Machines.
I, WILLIAM HENRY TURTON, of 230, Acacia Villas, Plumstead Common Road,
Plumstead, in the County of Kent, Mechanical Engineer, do hereby declare the
nature of this invention to be as follows.―
My invention relates to slotting shaping planing and other reciprocating machine
tools, and consists in adapting these machines to cut in both duections, namely
on the outward and mwaid strokes, by a specially constructed double tool holde
rocking on centies and actuated by a tappet motion By the 1ocking action of
the two tool holders and cutters one cutter 18 moved clear of the cutting plane.
while the other cutter is brought into action and tue versa Both tool holders
are always in sliding contact with one another so that one cannot move without
the other and the strain is transferred to the box or slide, and close to the cutters.
A safety spring catch on the tool holder snaps into a groove or over a notch so
as to prevent any movement of the cutters until the end of the stroke
Adjustable stops are clamped to the frame of the machine to suit the travel or
length of cut
A tappet rod or bar is attached to the tool holder at one end and to the tappet
lever or reversing the cutters at the other end
In the case of a planing and shaping machine the tappet stops are attached or
clamped to the table of the machine on to the work secured to the table according
to the nature of the work
These tappet stops actuate a pivotted lever fixed to the box slide and linked to
the tool holder so as to reverse the cutters at each end of the stroke
Several modifications of tappet aangements are required to suit the require-
ments of different machines

I, WILLIAM HENRY TURION, of 230, Acacia Villas, Plumstead Common Road,
Plumstead in the County of Kent, Mechanical Engineer, 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..

page_text: machine tools and consists in adapting and constructing these machines to cut m
both duections namely on the outward and inward strokes or travel by specially
constructed tool holders each rocking on a separate centre and each carrying a
separate tool with a suitable tappet motion.

and rice ves su Both tool holders are always in sliding contact with each other
so that one cannot move without the other and the strain in cutting is taken by

containing the tool holders can be attached to an existing machine or in new
machines made to take the place of the oidimai single tool box and holder

Adjustable stops are clamped to a bar or groove on the side of the machine to
suit the required stroke or travel of cut.

In a vertical slotting machine a connecting rod is attached to one tool holder
at one end and to a lever at the other This level is on a rocking shaft with
another tappet lever outside and in line with the stops so as to reverse the action
of cutters at each end of the travel.
The cam or gear for actuating the feed is made to act at each end of the stinke
or travel and where this invention is applied to existing machines with quick
return stroke 1 sometimes change the gear so as to make the travel each way
uniform.
In a planing machine I change the pulleys In new machines this 18 provided
for

In a planing machine the tappet, stops are attached or clamped to the table oi
work as the case may suit These stops actuate a pivoted lever centred under the
box and linked to one tool holder so as to reverse the cutting at each end of the
travel.
The automatic feed is made to act at each end of the travel.
One or more sets of tool holders may be in operation on one machine

Pis the tappet 1od adjustable in the level
Q (Fig 9 & 10) is one of the two stops clamped to the table or work S con-
sisting of,
Ran upright stalk with adjustable sliding od straight or bent to suit en-
cunstances and for reversing the action of cutters
H 18 the ordinary pivot and H2 the clamping screw for cutting at various angles
In Fig 7, and 8, L, L, are the ordinary adjustable tappet stops clamped to the
table S by the tee headed bolts T, T (The ordinary reversing tappet lever 18 not
shewn but 18 fixed on the same spindle as U)
U, is a special tappet lever for giving the automatic feed at each end of the
travel and is connected by a rod V, to a level W The said lever W, 18 fixed on
the ordinary spindle for actuating the feed.
The lever U, is loose on the spindle T, T', are tappet levers, centered at
T, T, and having projections for tapping and pulling back the lever U, to its
normal vertical position at the end each travel
In the ordinary single cutting planing machine, X, is the spindle which
reverses the travel of the table.
In this invention the feed of the cutters must be actuated twice, 122, once at
each end of the travel
When the table approaches the end of the travel the lever T', comes in contact
with the centre projection on the tappet U, pushing the rod V, thereby putting
on the feed, and in returning pulls the iod back again, to its normal position (as
shewn) When the table gets to the other end of its travel the other lever 1,
does the same
In the case of a slotting machine the ordinary automatic feed is used, the only
difference being that the cam is made to actuate the feed twice instead of once
In using hand feed the pawl is thrown out of gear, and this applies to all
machines.
flaving 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 18.-
1 Two separate tool holders with cutters rocking on two separate centies and
sliding on each other and automatically operated for cutting in two opposite
dnections, substantially as shown and described
2 Two separate tool holders in sliding contact and rocking on separate centres
n a tool box and actuated automatically so as to cut m both dnections sub-
stantially as shown and described
3. Two separate tool holders rocking automatically for cutting in both dnections
in a slotting machine shaping machine, and planing machine substantially as
shown and described
4 Tool holders with cutters 1ocking automatically for cutting in both direc-
tions, with automatic feed substantially as shown and described
5 Double rocking cutters with positive reversing action for cutting both ways
and automatic feed suitable for all reciprocating cutting machines substantially
as shown and described.

page_text: 6. Rocking cutters with positive action for cutting in both directions with
automatic feed and uniform tiavel to be adapted to all existing and new slotting
shaping and planing machines substantially as shown and described.
