for an Invention of "IMPROVEMENTS IN MACHINERY EMPLOYED IN THE
MANUFACTURE OF LEATHER FOR SETTING SCOURING, STRIKING OR PINNING,
PRINTING ROLLING, SLICKING, FLESHING, UNHAIRING, WHITING SHAVING AND
BRUSHING
"
PROVISIONAL SPECIFICATION left by the said Joseph Hall at the Office
of the Commissioners of Patents on the 3rd May 1883.

STRIKING OR PINNING, PRINTING, ROLLING, SLICKING, FLESHING, UNHAIRING,
WHITING, SHAVING, AND BRUSHING,"
The holder for the tool is mounted in swinging bearings, upon a carriage,
attached to a standard or upright and I employ springs or their equivalents over
the axles of the tool holder and within the carriage for the purpose of holding
down the tool whilst operating, and at the same time to allow of the tool adjusting
itself to suit the varying thickness of the material.
Motion is imparted to the swinging tool holder by a crank, such motion being
transmitted through a suitable connecting rod.
The movement of the tool on the material whilst operating is in a straight line
but it is lifted clear of such material for the return stroke.
I arrange the tool holder so that the tools may be removed from or brought up
to the work either separately or in combination this being effected by levers, cams
or screws actuated by the attendant.
The table is mounted horizontally below the tool holder on a suitable carriage,
so that it may be moved in any direction horizontally, such movement being
effected through the medium of wheels rollers or balls arranged so as to operate in
different directions. When preferred the table may be raised or lowered at

page_text: pleasure by ordinary means and it may be arranged also when preferred on springs
attached to the table carriage so as to be self adjusting to the various thicknesses
of the material.
When required I apply a sharpening apparatus which is brought up to the edge
of the tool or tools for sharpening purposes whenever necessary.
By a convenient arrangement I mount any number of tool-holders on the
carriage the tools in such holders being arranged so as to work together in one
direction or part of the number to operate in one direction and the remainder in
the other,
The tools used are varied in form or shape to suit the different operations
hereinbefore mentioned.
Work done on the above mentioned machine is of a superior quality and is
produced at a considerably less cost than by machinery hitherto employed for the
purpose.

By a convenient arrangement I mount any number of tool holders on the

The tools used are varied in form or shape to suit the different operations herein

Work done on the above mentioned machine is of a superior quality and is

purpose
And in order that my Invention may be more readily understood reference is
given to the accompanying drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS
Fig 1 is a side elevation Fig 2 an end elevation and Fig 3 is a plan of a machine
with a horizontal table and having my Improvements applied thereto. Fig 4 is a
side elevation and Fig 5 an end elevation of a machine with a drum shewing
another arrangement of my Improvements. Fig 6 is a side view and Fig 7 an
end view of my improved arrangement for sharpening the cutters or tools. Figs 8
to 13 shew details to be hereafter described.
In Figs 12 and 3 a is the standard or upright supporting in horizontal guides
the carriage b. c are the tool holders which are suspended or hinged in bearings
at d on the carriage b and I employ the springs e or their equivalents over axles d

page_text: of the tool holders c and within the carriage for the purpose of holding down the
tool whilst operating and at the same time to allow of the tools or cutters /
adjusting themselves to suit the varying thickness or other irregularities of the
material to be operated upon
Motion is imparted to the swinging tool holder o from the crank g through the 5
connecting rod h It will be seen that as the crank g rotates in the direction
shewn by the arrow during the forward motion the tools fare depressed on the
material to be operated upon but during the return stroke they are lifted clear of
such material, also by such motion the tools come down gradually on to the
material and in the same manner are raised clear of it
Figs 8 and 9 are respectively side and cross elevation of a tool carrier or holder
arranged for two tools so that the one may operate in one direction and the other
in the opposite direction and Fig 10 is a side elevation of a tool carrier arranged
for two tools both operating in the same direction, moreover in both arrangements
each tool is lifted clear of the material when not operating on the same
The table k is attached to the carriage which is mounted on wheels m. The
wheels m run on the rails n fixed to the carriage p the latter being mounted on
the wheels o. The axle bearings of the wheels o are arranged to move vertically
in guides cast on or attached to the framework of the carriage p. The carriage p
rests on the bearings of the wheel (o) axles by means of the bell crank levers
which are actuated by hand through the bevil wheels 8 shaft t wheels u and
shaft which latter has a right and a left hand screw at its ends the screw'd ends
working in nuts carried in the lower ends of the bell crank levers r
The carriage may be moved horizontally by means of the hand wheel w
shaft & pinion y. and rack z. The table k rests upon the carriage through the
intervention of the rollers 1. 1. By means of the arrangements just described it
will be seen that the table k may be moved horizontally in any direction and also
raised and lowered at pleasure When preferred springs may be attached to the
table carriage so as to make the carriage self adjusting to suit the various
thicknesses of the material
When required I apply a sharpening apparatus shewn in Figs 6 and 7 which is
brought up to the edge of the tool or tools for sharpening the same. In Figs 6
and 7 c is the tool holder and f the tool. The lever 2 carrying the sharpener 3 is
It will be
hinged in bearings.4 attached or cast on to the standard or upright a
seen that owing to the oscillation of the tool holder c on the axle d, the tool f
approaches the sharpener 3 towards the end of the forward stroke and when the
tool has reached the position indicated by the dotted lines 5 the nose 6 on the
cutter holder catches against the pin 7 attached to the centre of the toggle joint 8
thereby compressing the spring 9 and raising the sharpener 3 which is pressed
against the face of the tool f with a force equal to the strain on the spring 9 As
the connecting rod h and the tool holder c!continue the motion on d as a centre, the
upper end of the lever is forced backward drawing the sharpener 3 across the edge
and
of the tool f. When the reverse motion of the tool holder releases the lever
the spring 9, the lever 2 is drawn back to its original position by the spring 11;
and the toggle joint 8 and the sharpener are forced back into their original
positions by the springs 12 and 9 respectively
Fig 4 shews an arrangement by, which any desired number of tool-bolders c may
be mounted on the carriage 6 one half of these being arranged to work in one
direction and the other half in the opposite direction. By means of quadrants
eccentrics or levers I can raise the centre d thus releasing the tool f. Such
arrangements may be applied to one or more of the tool holders c the object being
to operate on any part of the material at pleasure
Figs 11 to 13 shew another arrangement of tool holder c in which the cutters f
are placed at an angle with the direction of motion; and in order to flatten down
any irregularities in the material to be operated upon out of the way of the tool
on the return stroke, I provide the dished plate 13 which presses down the
irregularities as it passes over them.

apparatus and mere modifications of the same substantially as and for
the purposes herein set forth.
Thirdly. The table k mounted and operated substantially as herein set
