page_text: WILLIAM PAUL, of Leeds, aforesaid, Currier and Leather Dresser, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR EMBOSSING, GLASSING, AND PRODUCING THE LEVANT
FINISH ON LEATHER," to be as follows:-
This Invention consists in a combination and arrangement of
machinery or apparatus adapted or adaptable to effect the several
purposes of embossing, glassing, and levanting leather, comprising a
table having the top or a portion of it capable of being raised and
lowered by means of an eccentric roller or equivalent means, on which
the leather to be operated upon is to be laid. Also a carriage or
moveable bracket or bearing suspended above the table and capable of
reciprocating in slides provided in fixed framework. To the bottom
part of this carriage or bracket is hinged at one end an arm, the other
end of which is provided so that the various tools or instruments cm-
ployed for the several purposes can be readily attached and carried
thereby, and this end of the arm is connected by an elbow joint to
another arm hinged to and supported by the top part of the carriage.
Reciprocatory motion is communicated to this carriage by means of a
rod hinged at one end to the clbow joint of the before-named rod and
connected at the other to a crank pin or stud carried by a rotary dise
or face plate. This stud is capable of being readily set to any desirable
amount of eccentricity with the axis of the face plate by the attendant
during the operation or action of the carriage, so as to vary the length
of stroke as required.. This is effected by having the stud fixed in a
block slideable in a groove cut across the face of the plate, and having
a screw pin passing through it, which is carried in a bearing fixed to
the plate, so as to rotate, but not move endwise, and on the end of this
pin is fixed a pulley. The face plate is capable of being moved laterally
or endwise on the shaft which carries it by means of a clutch and levers
operated by the attendant. The shaft of the face plate is supported in
a bearing which has a ring or ring flange projecting on each side of the
face plate, between which flanges the pulley on the screw circulates
or revolves, and when the plate is moved by the attendant operating
the lever the pulley is pressed against either one or the other of the
flanges according to requirement, which turns the screw and thereby
moves the stul block in its slide groove in or out to or from the centre
of the plate as required. Or other equivalent means may be adopted
'

page_text: performed, to be particularly described and ascertained in and by the
following statement and two accompanying Sheets of Drawings (that is
to say :-
This Invention consists in a combination and arrangement of
machinery or apparatus adapted or adaptable to effect the several
purposes of embossing, glassing, and levanting leather, comprising a
table having the top or a portion of it capable of being raised and
lowered by means of an eccentric roller or equivalent means, on which
table the leather to be operated upon is to be laid. Also a carriage or
moveable bracket or bearing suspended above the table and capable of
reciprocating in slides provided in fixed framework. To the bottom
part of this carriage or bracket is hinged at one end an arm, the other
end of which is provided so that the various tools or instruments em-
ployed for the several purposes can be readily attached and carried
thereby, and this end of the arm is connected by an elbow joint to
another arm hinged to and supported by the top part of the carriage.
Reciprocatory motion is communicated to this carriage by means of
a rod hinged at one end to the elbow joint of the before-named rod,
and connected at the other end to a crank pin or stud carried by a
rotary disc or face plate. This stud is capable of being readily set to
any desirable amount of eccentricity with the axis of the face plate by
the attendant during the operation or action of the carriage, so as to
vary the length of the stroke as required. This is effected by having
the stud fixed in a block slideable in a groove cut across the face of the
plate, and having a screw pin passing through it which is carried in a
bearing fixed to the plate so as to rotate, but not move endwise, and on
the end of this pin is fixed a pulley. The face plate is capable of being
moved laterally or endwise with the shaft which carries it by means
The shaft of the
of a clutch and levers operated by the attendant.
face plate is supported in a bearing which has a ring or ring flange
projecting on each side of the face plate, between which flanges the
pulley on the screw circulates or revolves, and when the plate is moved
by the attendant operating the lever the pulley is pressed against either
one or the other of the flanges, according to requirement, which turns the

page_text: screw,
and thereby moves the stud block in its slide groove in or out, to
or from the centre of the plate, as required; or other equivalent means
may be adopted to enable the attendant to move the crank pin or stud,
so as to vary the length of stroke according to requirement while the
machine is in motion.
In order that this Invention may be clearly understood reference is
given to the two accompanying Sheets of Drawings of machinery or
apparatus constructed in accordance therewith, wherein Fig. 1 is the
front elevation; Fig. 2 is the side elevation; and Figs. 3 and 4 are
details of the same.
A is the table having a portion of its top B mounted on eccentrics C
fixed on a shaft D supported in the frame of the table, and capable of
being turned by means of a handle D' fixed on the out end thereof, so
that this portion of the table may be readily raised or lowered by the
attendant; E is the carriage or bracket suspended in slides F fixed to
the under side of a floor beam F¹ in a suitable position above the table,
or these slides may be fixed to a suitable framework provided for the
purpose in connection with the table; G is the arm hinged to the
carriago or bracket, and which is connected by an elbow-jointed arm or
rod H to another arm I hinged at 1 and supported by a bar I to the
top part of the carriage, and which arm I is pressed by a spring J, the
pressure being adjusted by a screw J¹. To this arm G is attached
the glass or instrument G¹ used for glassing leather, which may be
exchanged for other instruments used for embossing or levanting leather,
as required. Reciprocatory motion is given to the carriage by means
of the connecting rod K, which is jointed at one end to the arm H, and
at the other end to a crank pin or stud L carried by a disc or face
plate M and leather straps K' and K². This crank pin or stud is fixed
to a slide block N, attached to which is a screwed nut P fitting on a
screwed shaft Q supported in a lug on the disc, and on one end of which
shaft is fixed a friction roller R. The side block is guided in its motion
by checks M' and M* fixed to the disc or face plate, and the said disc
is mounted on a shaft S which is capable of endwise motion by
means of the forked lever T, which is hinged to the bracket U taking
into a groove on the shaft and connected by a rod V to a lever W fixed
upon one end of a shaft W', to the other end of which is attached two
treddles X and X', which can be operated by the attendant, so as to

page_text: move the shaft S endwise in either direction, a spring Y serving to bring.
it back to the normal or intermediate position, as shewn. This disc or
face plate is supported by and enclosed within a circular hanger or box
fixed to the beam, the sides of which are open except a ring flange on
each side, a and b, projecting inward sufficiently for the friction roller
to bear against them when the disc is moved sideways by the attendant
acting on the treddles. Fig. 3 is a vertical section of the hanger or box
and the disc and the screw nut and crank pin; and Fig. 4 is an cnd
view of the said disc with the said crank pin, block, nut, screwed shaft,
and friction pulley.
It will now be readily seen that the attendant by pressing with his
foot on the treddle X the disc will be moved laterally pressing the
friction roller against the flange a, which when the disc is rotating will
turn the screw and thereby move the nut and with it the slide block
and crank pin nearer to or further from the centre of the said disc
according to the direction of rotation, thus varying or altering the stroke
or extent of motion of the carriage. And by pressing upon the tredḍle X¹
the friction roller will be pressed against the other flange and the
screw will be turned in the opposite direction, thus altering the stroke
in the reverse direction.
It will now be evident that this machine or apparatus is under the
immediate control of the attendant, both as to amount of pressure lic
may require to apply to the leather under operation, and also as to
the length of stroke. Also that the glass instrument G, now shown
as fixed in the carriage or reciprocatory frame may be changed for an
embossing roller, slicker stone, "dummy" roller, or other instrument
used for purposes as set forth.
Having thus described the nature of our said Invention, and shown
by Drawings in what manner the same is or may be performed or carried
into practical operation, we would have it understood that we do not
confine ourselves to the preciso details herein set forth, but what we
claim as of our Invention is,-
Firstly. The combination and arrangement of machinery or apparatus
for purposes and in manner substantially as shown and described.
Secondly. The method or means of varying the position of the crank
pin so as to alter the length of stroke whilst the machine is in motion,
as hercin shewn and described.

page_text: Thirdly. The method or means of raising or lowering the table or a
portion thereof for the purpose of applying more or less pressure of the
instrument upon the material under operation.
In witness whereof, I, the said Thomas Haley, for and on behalf
of myself and the said Sam Haley, Sugden Haley, and John
Haley, and William Paul, have hereunto set my hand and scal,
this Second day of November, in the year of our Lord Onc
thousand eight hundred and seventy-one.
