n Improved Machine for Cutting Boot and other Laces and the like.
I, FREDERICK WARBURTON, of 47, Markeaton Street, in the County Borough
f Derby, Leather Merchant and Manufacturer, do hereby declare the nature of
his invention to be as follows:-
The object of this invention is to expedite the cutting of boot and other laces
nd the like, and also to ensure the "butts" of leather or other material being
" laces"
of perfectly even thickness or width and to provide
ut into strips or
cans for varying the said width, thickness or gauge as desired.
In carrying out my said invention I provide a bed mounted on suitable
standards, and upon the former I mount the parts to be hereinafter described.
Upon this bed is fixed a table at the back of which is bolted or otherwise secured
vertically adjustable knife; slightly in front of this knife and in suitable
bearings in a longitudinal recess is placed a milled feed roller: the bed, table,
feed roller and other parts of the machine to be hereinafter described being of a
sufficient length to accommodate or take any length of leather butt, or other
material required.
At or near each end of the table I provide a standard carrying and being con-
nected to each other by means of a top plate. In suitable guides on the inner
faces of these standards is arranged a top roller carrier, this carrier has a longi-
tudinal groove or recess on its underside in which is held a milled roller adapted
to engage the bottom feed roller (already described as being recessed in the
table) by means of pinions at the ends thereof.
The top roller carrier is provided with suitable lifting rods which pass through
the top plate already mentioned and over the latter mounted in suitable brackets
or bearings thereon is a shaft carrying levers adapted to operate the lifting rods,
the said shaft and levers being operated by means of a treadle or the like:
From the top roller
between the top plate and upper face of the top roller carrier are arranged
springs tending to keep the top roller on the bottom one.
carrier there passes a rod operating an indicator shewing what thickness of leather
or other material is being fed through the rollers so that the operator may know
how to gauge the feed as will be hereinafter described.
Close by the side of and beyond the top roller carrier and working in the same
or similar guides is a presser-foot which is intermittantly lifted by a beam
having eccentric straps at each end in which work eccentric blocks carried on or
secured to the ends of shafts supported in suitable head stocks or bearings bolted
5 to the bed: one shaft being driven direct and the other connected by suitable
gearing.
On the front side of the beam is bolted or otherwise secured another vertically
adjustable knife moving with the said eccentrically actuated beam.
The top roller carrier, the presser-foot and the knife carried by the beam are
10 kept in contact by means of front and back adjusting brackets.
The feeding apparatus, which is intermittant and adjustable, consists of a

page_text: ratchet wheel on the end of a shaft connected with the pinions of the rollers, on
said shaft is a loose lever carrying pawls to engage the ratchet wheel; this lever
is operated through suitable connections by means of a cam on the eccentric
shaft. To adjust the feed 1 employ a screw stop to limit the stroke of the lever
carrying the pawls.
It is evident that without departing from the spirit of my invention I may
vary the details to suit individual requirements such for example as by sub-
stituting a crank or cranks for the eccentrics, or employing a claw feed instead
of the roller feed.

An Improved Machine for Cutting Boot and other Laces and the like.
I, FREDERICK WARBURTON, of 47, Markeaton Street, in the County Borough
of Derby, Leather Merchant and Manufacturer, 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:-
"
The object of this invention is to expedite the cutting of boof and other laces
and the like, and also to ensure the "butts of leather or other material being
cut into strips or
*laces "
of perfectly even width and to provide means for
varying the said width, or gauge as desired.
Referring to the drawings which form a part of this specification.
Figure 1 is a general plan to a small scale looking downwards upon my
improved machine.
Figure 2 is a part front elevation to an enlarged scale shewing the feeding
apparatus as will be hereinafter described.
Figure 3 is a part end elevation of the latter.
Figure 4 is a part back elevation of certain parts of the machine to be herein-
after referred to.
Figure 5 is a vertical section on line a, a of Figure 4.
Figures 2, 3,
and 5 are drawn to the same enlarged scale.
In carrying out my said invention I provide a bed A mounted on suitable
standards, not shewn upon the drawings, and upon the former I mount the parts
to be hereinafter described. Upon this bed is fixed a table B at the back of
which is bolted or otherwise secured a vertically adjustable knife C; slightly in
front of this knife and in suitable bearings in a longitudinal recess 131 is placed
a milled feed roller D; the bed, table, feed roller, and other parts of the machine
to be hereinafter described being of a sufficient length to accommodate or take
any length of leather butt, or other material required.
At or near each end of the bed A. I provide a standard E E' carrying and being
connected to each other by means of a top plate F, upon Figure 1 this top plate
is shewn removed for the sake of convenience in illustrating the parts below it.
In suitable guides on the inner faces of these standards is arranged a top roller
carrier G, this carrier has a longitudinal groove or recess G¹ on its underside in
which is held a milled roller D adapted to engage the bottom feed roller 1)
(already described as being recessed in the table) by means of pinions H H at
the ends thereof.
The top roller carrier is provided with suitable lifting rods I which pass
through the top plate I already mentioned and over the latter mounted in suit-

page_text: le brackets or bearings thereon is a shaft K carrying levers Ladap
e lifting rods, the said shaft and levers being operated from one end by means
a treadle or the like from the rod M: between the top plate and upper face of
he top roller carrier are arranged springs N tending to keep the top roller on the
ottom one. From the top roller carrier there passes a rod 0 operating through
he means of lever 01 and other suitable means such as rack 02 and pinion 03
n indicator 0 shewing what thickness of leather or other material is being fed
hrough the rollers, so that the operator may know how to gauge the feed as will
e hereinafter described.
Close by the side of and beyond the top roller carrier G. and working in the
same or similar guides is a presser-foot P which is intermittantly lifted by means
of a bracket with roller Q¹ on a beam Q having eccentric straps R at each_end
in which work eccentric blocks S carried on or secured to the ends of shafts T T¹
supported in suitable head stocks U or bearings bolted to the bed A; one shaft T¹
being driven direct and the other connected by suitable gearing V and shaft V¹.
On the front side of the beam Q is bolted or otherwise secured another ver-
tically adjustable knife C¹ moving with the said eccentrically actuated beam Q.
The top roller carrier G, the presser-foot P. and the knife C carried by the
beam Q are kept in contact by means of front and back adjusting brackets W WI
respectively.
The feeding apparatus, which is intermittant and adjustable, consists of a
ratchet wheel X on the end of a shaft X connected with the pinions H H¹ of the
rollers D D by means of back pinions H2 and H3, on said shaft is a loose lever Y
carrying pawls Y¹ to engage the ratchet wheel; this lever is operated through
connecting rod Z, lever (the latter being pivotted to the standard E¹) by means
of a cam on the eccentric shaft T', bracketted to standard E¹ is an adjustable
stop to limit the stroke of lever ¹. To adjust the feed I employ a screw stop =4
to limit the stroke of the lever carrying the pawls; on the end of the said screw
stop is an index wheel having a pointer.
It is evident that without departing from the spirit of my invention I may
vary the details to suit individual requirements such for example as by sub-
stituting a crank or cranks for the eccentrics, or employing a claw feed instead
of the roller feed.
Having now particularly described and ascertained the nature of my said
5 invention, and in what manner the same is to be performed, I declare that what
I claim is

actuated beam carrying an adjustable knife in combination with a stationary
