IMPROVE- MENTS IN MACHINERY, EMPLOYED IN THE MANUFACTURE OF LEATHER
Year: 1884

page_text: I WALTER WARWICK, Currier, Residing at No 52 Haworth Street, Bolton, in the
County of Lancaster, do hereby declare the nature of my invention for IMPROVE-
MENTS IN MACHINERY, EMPLOYED IN THE MANUFACTURE OF LEATHER, to be as
follows:-
Consists of an improved tool-holder. or holders, attached or fixed to a connecting
rod, which said connecting rod by being attached by an axle pin, is caused to rock
in slide blocks or shoes, that slide along parallel guides, of a concave curvilinear
form, attached to a standard or frame.
1.1
Motion is imparted to a crank to which the aforesaid connecting rod is attached.
The above improvements, can be applied to Unhairing, "Fleshing, Scouring,
'Setting, Stretching and. Setting, Shaving or Whitening, Striking out, Rolling,
Printing, Glazing, Glassing, and Finishing, Hides and Skins.
The tool-holder consists of a jaw, or box, that may be set to any angle required,
which tool-holder slides in a hollow casing, containing an elastic cushion of
vulcanised india rubber, or like substance, and a steel spiral or other shaped
spring.
The tool-box or jaw and casing combined, are attached to the end of a connecting
rod.
At a short distance from the end of the connecting rod, is fixed an axle pin,
which swings or rocks to a limited extent, in slide blocks or shoes, these slide blocks
slide along curvilinear guides of a concave form, which are placed at parallel dis-
tances from each other, and are attached to a frame of an elongated horse shoe, or
other convenient form of standard.
The curvilinear guides move or slide up and down, in slides fixed to the standard,
or frame, and are supported by springs.
To depress or lower the guides, I use eccentrics, screws, levers, or cams, by which
means the pressure can be adjusted on the material operated on, while the machine
is working, or at rest.
The table on which the material is laid to be operated on, slides on wheel rollars
attached to arms radiating from a centre, which centre can be elevated by means
of screws, levers, or other well known appliances, enabling the attendant thereby,
to move the table in any required direction.

page_text: If requisite, a carriage moving on wheels, which run on rails, can be used
instead of the above radiating arms, with rollars attached.
The tool travils along the material to be operated on, in a straight line, and
returns with a curvilinear clearing stroke, motion being imparted to the connecting
rod, by a crank.
Any requisite number of tool-holders, and tools can be attached to the connecting
rod, such tools can be placed on both sides of the axle pin, so as to give a working
stroke both ways, the connecting rod reciprocating.
When the tool edge is required, to be kept to an invariable angle, to the table
and material operated on, I attach a tool-box or jaw, with a projection behind, to
which projection, is fixed by a joint that can be clamped in any position an upright
guide or spindle, which works in a guide box, which guide box with slides attached,
that slide along parallel guides of a straight form, placed near to the aforesaid
curvilinear guides, but without diminishing their utility, may be placed on the
opposite side of the tool-box.
To roll leather, I place friction rollars on the slide blocks, and a rollar on
the tool-box, or holder, which on working presses down and rolls the leather
operated on.
To sett and stretch at one operation, I place two connecting rods, with the
requisite tools attached, and working in slide blocks, by means of an axle pin,
which slide blocks, slide along curvilinear guides, placed above each other, with the
concave faces opposite to one another, the connecting rods are attached to two
crank pins, fixed in two wheels, which wheels, are geared together, the material to
be operated on, is fixed in an open frame, and placed between the tools.
On the wheels being actuated, the leather is stretched and sett at one operation.
In working hides and skins, in which the overhanging frame, or standard, is
inconvenient, I connect the connecting rod, with the slide blocks and axle pin,
working in the curvilinear guides, with hanging links, by which means the standard
or frame, is placed upright, and the table placed in a sloping direction, thereby
allowing the material to be seen to better advantage, by the attendant in the course
of operation.
The stroke of the tool, can be either straight, convex, or concave, with return
clearing motion, and the table made to suit the various operations required. .

page_text: I WALTER WARWICK, Currier, Residing at No. 52 Haworth Street Bolton in the
County of Lancaster do hereby declare the nature of my invention for LMPROVE-
MENTS IN MACHINERY EMPLOYED IN THE MANUFACTURE OF LEATHER and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement
Consists of an improved tool-holder or holders, attached or fixed to a connecting
rod, which said connecting rod by being attached by an axle pin, is caused to rock
in slide blocks or shoes, that slide along. parallel guides of a concave curvilinear
form, attached to a standard or frame..
Motion is imparted to a crank to which the aforesaid connecting rod is attached.
The above improvements, can be applied to Unhairing, Fleshing, Scouring,
Setting, Striking out, Rolling,. Printing, Glazing, Glassing and Finishing Hides and
Skins.

The tool-holder consists of a jaw or box, that may be set to any angle required,
which tool-holder slides in a hollow casing, containing an elastic cushion of
vulcanised india rubber, or like substance and a spiral or other suitably shaped
spring, which is adjusted to the requisite pressure.
The tool-box or jaw and casing combined are attached to the end of a connecting
rod.
At a short distance from the end of the connecting rod, is fixed an axle pin,
which swings or rocks to a limited extent, in slide blocks or shoes, these slide
blocks slide along curvilinear guides of a concave form, in relation to the required
elevation or depression of the tool holders at the various parts of the stroke, which
are placed at parallel distances apart from each other and are attached to a frame
of an elongated horse shoe; or other convenient form of standard.
The curvilinear guides move or slide up and down, in slides fixed to the standard
or frame and are supported by springs.
To depress or lower the guides, I use eccentrics, screws, levers, or cams, by which
means the pressure can be adjusted on the material operated on, while the machine
is working or at rest.:
The table on which the material is laid to be operated on, slides on wheel rollars
attached to arms radiating from a centre, which centre can be elevated by means
of screws, levers, or other well known appliances, enabling the attendant, thereby,
to move the table in any required direction. Upon this table the material required.
to be operated upon is placed.
If requisite a carriage moving on wheels, which run on rails, can be used instead
of the above radiating arms with rollars, attached.
The tool travels over the material to be operated on, in a straight line being
guided by the curvilinear guides, and acts upon the material to be treated. It
'

page_text: returns with a curvilinear clearing stroke, motion being imparted in each case to
the connecting rod by a crank..
Any requisite number of tool holders and tools, can be attached to the connecting
rod, and be detached as occasion requires, such tools can be placed on both sides of
the axle pin so as to give a working stroke both ways, the connecting rod recipro-
cating.
When the tool edge is required to be kept at an invariable angle to the table and
material operated on, I attach to the connecting rod one or more tool boxes, or jaws
with projections behind, to which projections are fixed by joints, that can be
clamped in any position, upright guides or spindles which work in a guide box
which guide box, with slides attached, that slide along parallel guides of a straight
form, placed near to the aforesaid curvilinear guides, but without diminishing
their utility may be placed on the opposite side of the tool-box or other suitable
position.
To roll leather I place friction rollars on the slide blocks, and a rollar on
the tool-box or holder, which on working presses down and rolls the leather
operated on.
To sett and stretch at one operation I repeat underneath the table, the above
mentioned tools, curvilinear guides and other appliances, and work them by means
of a pair of geared wheels and connective rods. The lower tool operates upon the
under side of the leather, or skin, through a slot or opening in the table.
The sweep of the tool may be varied from a straight motion, by extending or
contracting the position of the tool holder, in relation to the axle pin. If the tool
holder is placed further from the axle pin, the stroke of the tool will be concave, or
convex, according to the distance from the axle pin.
