IMPROVEMENTS IN MACHINES FOR CHAMFERING THE ENDS OF LEATHER BELTING
Year: 1880

page_text: LETTERS PATENT to Jean Michel Joseph Fecken, of Aix-la-Chapelle, in the
German Empire, Engineer, for an Invention of "IMPROVEMENTS IN MACHINES
FOR CHAMFERING THE ENDS OF LEATHER BELTING."
PROVISIONAL SPECIFICATION left by the said Jean Michel Joseph Fecken
at the Office of the Commissioners of Patents on the 5th November 1880.
JEAN MICHEL JOSEPH FECKEN, of Aix-la-Chapelle, in the German Empire,
Engineer. "IMPROVEMENTS IN MACHINES FOR CHAMFERING THE ENDS OF
LEATHER BELTING."
My Invention has for object the chamfering or paring of the ends of leather
belting, no matter the width of such belting, by means of my improved machine
hereinafter described, whereby the joints are finer and better made than by the
modes heretofore employed for the purpose, and with a greater saving of time,
while the cuttings or parings can be rendered utilizable.
In carrying my Invention into effect, the leather belting to have its end or ends
chamfered or pared is held or secured upon a moveable upper table by a screw
press, with the end to be chamfered or pared passing over a roller, which is held or
supported by two rollers running on the said table. When the table moves
forward the belting is carried along with it, and the lower rollers are caused to
revolve by reason of their frictional contact with the table, and thus communicate
motion to the upper roller; this table is inclined forwards so that the rollers
gradually rise, and thus the end of the belting is chamfered or pared in an inclined
direction, or to the shape of a wedge by means of a knife or cutting blade suitably
mounted and directed against the belting. According to the inclination of the
upper table the more or less will be the chamfering or paring.
Springs extending across the machine and acting like fingers keep the belting
pressed against the upper roller, and by being so contrived and operating in such
manner, they press the belting equally, notwithstanding any inequalities which
might exist in the thickness of the belting.
The upper table rests in front on a screw, and at back upon projections which
take into wedge shaped or other suitably shaped pieces. The length of the
chamfering or paring is regulated by a set screw or the like, and by sliding the
wedges by means of another screw and by levers.
A lower table carries the upper table which rests upon it by means of the
aforesaid projections being locked between other projections on the lower table, and
this latter slides horizontally in the frame work of the machine when operated by
means of a rack and pinion, gear wheels, and a flywheel.

JEAN MICHEL JOSEPH FECKEN, of Aix la Chapelle, in the German Empire,
Engineer. "IMPROVEMENTS IN MACHINES FOR CHAMFERING THE ENDS OF
LEATHER BELTING,"
My Invention has for object the chamfering or paring of the ends of leather
belting of any width, by means of my improved machine hereinafter described,
whereby the joints are finer and better made than by the modes heretofore
employed for the purpose, and with a greater saving of time, while the cuttings or
parings which are removed at one cut and in one sheet or piece can be utilized.
In carrying my Invention into effect, the leather belting to have its end or ends
chamfered or pared is held or secured upon a moveable upper table by a screw
press, with its end to be chamfered or pared passing over a roller, which is held or
supported by two rollers running on the said table. When the table is moved
forward the belting is carried along with it, and the lower rollers are caused to
revolve by reason of their frictional contact with the table, and to thus com-
municate motion to the upper roller. This table is inclined forwards so that the
rollers gradually rise, and thus the end of the belting is chamfered or pared in an
inclined or wedge shaped direction, by means of a knife or cutting blade suitably
mounted and directed against the belting. According to the inclination of the
upper table, the chamfering or paring will be the more or less acute.
Springs extending across the machine and acting like fingers keep the belting
pressed against the upper roller, and by being so contrived and operating in such
manner they press the belting equally, notwithstanding any inequalities which
might exist therein.
The upper table rests in front on a screw, and at back upon projections, which
take into wedge shaped or other suitably shaped pieces. The length of the
chamfering or paring is regulated by a set serew or the like, and by sliding the
wedges by means of another screw or by levers.
A lower table carries the upper table which rests upon it, by means of the
aforesaid projections being locked between other projections on the said lower
table, and this latter slides horizontally in the frame-work of the machine when
operated by means of suitable gearing."
And in order that my Invention may be more fully understood and readily
carried into effect, I proceed to describe same aided by the Drawings hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.

page_text: is chamfered or pared to a wedge shape by means of the knife M which is
mounted on the holder T, that is to say, the belting is chamfered or pared the
more, the greater the inclination of the upper table O.
F, F, are springs secured to the underside of the holder W; they act like fingers,
and press the belting against the upper roller R. These springs at the same time
permit any inequalities in the leather belting under treatment to pass freely over
the roller R without retarding its motion. The upper table rests in front on the
screw 8, and at back it is provided with projections n, n, which rests on wedge
shaped pieces k, k. These wedge shaped pieces serve to regulate the length of
chamfer or paring by means of the regulator V and the two armed levers h, h¹,
(Fig. 3).
X is a lever handle which is attached to the blade or knife holder, and which
serves to raise the springs F, F, so that the blade or knife can be seen and its
adjustment properly regulated.
U is the lower table, which when moved carries the upper table resting upon it,
which is engaged by its projections n, n, being locked between the projections o, o,
on the lower table, whilst the former slides horizontally between the frames G, G¹,
when operated by means of the fly wheel a which imparts motion to the pinion t
in gear with the rack Z.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim,-
1. The improved machine for chamfering or paring the ends of leather belting,
as described and shown in the Drawings.
2. The employment of rollers arranged upon a moveable table by which they
are moved and arranged under a cutting blade or knife, substantially in the
manner and for the purpose described.
3. In combination with the rollers, the springs acting like fingers for keeping
the leather belting in contact with the upper roller, as described and shown.
In witness whereof, I, the said Jean Michel Joseph Fecken, have hereunto
set my hand and seal, this Twenty eighth day of April, in the year of
Lord One thousand eight hundred and eighty one.
