Improved Method of and Machine for Applying Edging or Beading
to Boot Uppers.
JOHN WILLIAM URQUHART 52 Empress Road Liverpool Engineer do hereby
declare the nature of this invention to be as follows:-
My invention relates to a machine or apparatus designed to perform that class
of work known in the boot and shoe trade as button fly beading or piping. It
more particularly relates to that kind of beading known as scallop beading.
Hitherto this operation has been effected by hand. In this process the strip of
material called beading is taken and gradually worked round the edges required to
be beaded and attached thereto by paste. My machine is designed to firstly form
or curve the beading in the shape required for a scallop or scallops or other
portion of the boot upper. Secondly, to convey that form or shape to the leather
or other material and thirdly to attach it thereto by means of pressure and paste
or other suitable means. In a modification of the machine the beading may be
formed directly upon the surface of the leather to which it is required to be
attached.
The operation of the machine is briefly as follows: The material called

of the carrier, and arranged in a series in the form or path required I employ as
a retaining device a line of pins distributed in a holder I call a pin plate. In the
movement of the carrier the beading, as it flows therefrom becomes impaled or
spitted upon the pins aforesaid. The length of beading is thereby retained in
form or shape and is severed from the carrier by means of a cutter worked by the
machine. The second step in the operation is to transfer this form or shape to the
leather or other material the edge of which it is desired to bead. To effect this
the pin plate aforesaid is automatically shifted from beneath the carrier to a
convenient position, over which the leather, already gummed or pasted is held in
contact with a suitable guide. The final step in the process consists in bringing
pressure to bear upon the leather and at the same time withdrawing the retaining
pins and so releasing the form of beading. The gummed surface is thereby
attached to the latter and the operation is complete.
In the modified form of the machine already mentioned the beading as it flows
from the carrier may be attached to or retained directly by the surface of the
leather either by means of gum upon the beading itself or upon the surface to
which it is to be transferred.

Improved Method of and Machine for Applying Edging or Beading
to Boot Uppers.
1, JOHN WILLIAM URQUHART of 39 Elm Road, Walton, Liverpool, Engineer,
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 :-
My invention relates to a machine or apparatus designed to perform that class
It more
of work known in the boot and shoe trade as button fly bending.
particularly relates to that kind of beading known as scallop beading, edging or

page_text: piping. The invention may however be adapted to apply the beading to any
other portion of the boot or shoe. It may also be used to apply beading to other
substances as cloth, paper etc. The machine is designed to perform the operation
in the course of a cycle of movements as follows:-
The strip of prepared beading or piping is fed into the machine. It passes
through a guide or sheath adapted to revolve, oscillate or vibrate in a prearranged
path. This guide carries the beading aforesaid throughout the course of the shape
or form it is desired the strip of beading shall assume. The shape or form thus
imparted to the beading is retained or fixed by the device of rolling the beading,
during the formation of the shape, upon the points of a series of retaining pins.
The beading becomes partially or wholly impaled upon the pins. The form or shape
eing thus given to the beading, this portion of it is severed from the remainder
by the action of a chisel, knife, cutter or scissors timed to work by the action of
the machine.
The next step in the movements of the machine consists in the raising of the
guide, roller and chisel aforesaid from contact with the pins aforesaid. The
platform containing the pins, with the form of beading now moves away from
under the guide and by performing a half circle comes to rest directly under a
pressure device. But this motion may be reversed, and the guide may move
away, the pressure device taking its place. This latter device forms a portion of
the machine. The beading still impaled upon the retaining pins is next trans-
ferred to the ready pasted leather, paper or other substance it is desired to bead.
This is effected by the descent of the pressing foot and the withdrawal of the
retaining pins from the beading. The pressing foot serves to effect the required
contact of the pasted substance and also to push down, or back the retaining pins.
The beaded material, carrying the beading, may now be moved from beneath the
press, which immediately rises for that purpose.
Instead of applying the paste or other fastening medium to the edge to be
beaded it may form part of or be applied to, the beading itself. Instead of
applying the beading to the pins aforesaid the beading may be transferred or
rolled directly upon the material to be beaded, which may be gummed beforehand.
Or the beading itself may contain or be faced with a suitable retaining medium.
Or the beading inay, instead of being transferred to pins, be fixed by the guide
within a groove in the receiving platform. Or the beading may be held down or
in position by means of nippers or clamps.
The action of the machine may be regarded as duplex. This is effected by
the employment of two platforms and sets of retaining pins. These are set upon
an axis and are brought alternately beneath the guide and the pressing off' device
already mentioned. Hence, while the person operating the machine is engaged in
receiving a form of beading from beneath the press the guiding and transfixing
arrangement aforesaid is engaged in rolling on the succeeding form of beading.
By these means the time that would otherwise be wasted in waiting for the action
of the guide is saved.
And in order that my said invention may be fully understood I shall now
proceed to more particularly describe the same and for that purpose shall refer to
the several figures in the annexed sheet of drawings.
Fig. 1 represents the chief parts of the kind of machine I prefer to use,
shewn artly in section. a represents the main axis or shaft, carrying at its
lower extremity the guide block . This guide block carries at its lower end a
roller. The guiding arm d, is jointed at d. This arm carries at its lower
end a suitable sheath shaped to receive the beading, and also a small roller 1, +0
that the beading may accurately follow the motions of dd. The guide arm
aforesaid also carries a friction roller, capable of adjustment to the left or
right of dd. The roller g bears continually against the interior of the excentric
ring or forming cam h. The continuous contact of 9 against his ensured by means
of the antagonistic spring i. The action of the guide is as follows:-If the
ring be a true circle the sheath and roller, upon the rotation of the shaft a, will

page_text: nove also in a circle. But if the ring h be excentric a similar path will be
described by e. If the shape of the ring be partly a circle and parily parabolic
the scallop shape so much used in boot work will be described by e.
But
The beading is led down through the main shaft a, under the roller e and also
under the roller c. The function of e is that of a rolling presser. Its periphery is
lower than that of e. When the guide has completed its travel or path the
beading is cut off by means of a chisel. This part (not shown in Fig. 1) is
attached to or moves in the guide block directly behind the guide arm d d'.
Normally, or when not in action the chisel or cutter is held up clear of the
platform and beading by a portion of its stem bearing upon an upper ring k
at a suitable part of a gap is cut and a spring forces the chisel or cutter suddenly
downwards, cutting through the beading. These parts of the machine form the
guiding, pressing and cutting off portion of the machine. The spring i may be
dispensed with by applying an inner ring at h, forming in this way a grooved or
channel cam.
The size of the form of
Any required shape may be given to h.
heading made by the machine may be adjusted either by the size of the cam / or
by adjustment of the roller g. Or it may be varied by adjusting the fulcrum at ď¹
or the guide sheath at e.
Instead of the jointed arm d d'a slide or shoe moving in a horizontal plane, and
carrying the guide e may be used. This slide may be similarly actuated by a cam,
and a spring inay or may not be employed as in the above instance.
The cam may in either case be overhead and may move the guiding arm or slide
by means of a vertically moving wedge, or a double sided cam groove.
Reverting to Fig. 1 the guide block with the main shaft a may be raised clear of
the under platform by means of a spring continuously pressing these parts
upwards. This is effected by means of the ring a', having a gap cut in its lower
face as represented into which the roller shewn attached to shaft a rises at the
proper time.
The arrangement of the parts in the guide block is made more apparent by the
view of its under side (as looked at from beneath) given in Fig. 2. The pressing
roller is represented at e and the smaller guiding roller with its beading sheath at c.
The action of c would in some cases be imperfect without the after action of the
following plate represented at c'. The function of the plate is to maintain the
beading in a flattened condition after the roller has caused its impalement upon
the pins. At is shewn the cutting edge of the chisel cutter or knife which is
set at an angle preferably radial to the centre of motion as represented. It dips
downwards through the plate through the gap shewn.
Reverting now to Fig. 1 represent the double platform already referred to,
which carries the two sets of impaling pins. These are represented at an. The
pins are fixed in a manner convenient for removal in the disks shewn, having
plungers or stems, mm. These are capable of slight vertical motion carrying the
pins with them. In the position shewn at m the plunger cannot be pressed further
downwards owing to its lower extremity being in contact with the bed of the
machine as represented. At m is shewn a recess in the bed o, into which the
plungers shown in that position are free to drop. The further end of this recess
in the direction of rotation forms a gradual incline and its effect is to raise the pins
to their original position through the platform after the beading has been
transferred. The disk, which is usually faced with an elastic substance forms
the face of the press aforesaid. It carries a plunger and a yielding spring set in
the pressure shaft as represented. The small rode is fastened to the pressure rod
above and moves freely through ». The effect of this arrangement is that the
face of first presses upon the material to be beaded and practically fixes it. Any
further downward motion of the press rod i will carry with it irrespective of .
The end of serves thus to press downwards the pins out of the beading after the
latter has been fixed by the pressure of . This ensures that the beading shall
be well fixed to the material before it is released from the control of the pins.
or may carry an adjustable guide again-t which to place the scallops or other

page_text: forms being beaded. Or the guide may be attached to any fixed portion of the
machine.
The presser rod we may be actuated by means of a cam rotating with the main
shaft a.
Or it may be moved by means of a crank pin projecting vertically from a
disk or arm rotating with a, and actuating the rod to through a horizontal sliding
guide and a bell crank in order to change the horizontal motion of this part to the
required vertical motion of the presser rod te.
q
The platform is free to move with the shaft when the projections ppl are
clear of the trigger
But normally, while the machine is either rolling on the
heading or pressing off, the trigger retains the platform in the position shewn,
At the proper moment (that is when the chisel Fig. 2 has cut off the length of
beading) the trigger is released by the raising of the shaft and disk lands by
means of the springt. The raising of is effected by its upper end being pressed
by the spring into a cam gap formed in the under side of a horizontal disk (not
shown) rotating with the main shaft a. The platform is at this moment caused
to move through half a revolution by means of a toothed friction wheel (not
shewn) rotating with the main shaft a. This wheel is geared into a pinion
attached to the upper end of the shaft 2. The friction gear wheel above
mentioned is only free to move when the rise of the shaft releases the trigger q
from contact with projection por p'. By these means the platform is carried
rapidly through the half revolution. thus changes place with a'.
The diagrams Figs. 3 and 4 represent, in plan, the faces of the platform at nn'.
They shew the line of impaling pins set out to form a scallop shape. At n³ slips
of brass are inserted against which the chisel or cutter already described severs the
beading.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that
what I claim is
--
(1) In a machine designed for beading boot or other scallops or other parts of
small size the use of a guide carrying the beading which may be caused to move
in any prearranged path more or less excentric or of any other required shape
within its complete revolution.
(2) In conjunction and combination with the guide aforesaid of a pressure
roller and plate and a severing chisel cutter or knife for the purpose already fully
described.
(3) In conjunction and combination with the guide, pressure roller and chisel
aforesaid the use of a series of impaling points capable of being withdrawn or
pressed below the level of the platform or a groove, clamps or nippers for the
purpose of retaining the beading in combination with the guide aforesaid.
(4) The combination of a double platform and set of pins cach platform capable
of being rotated alternately to a position beneath the guide aforesaid for the
purpose hereinbefore described.
(5) The combination of a spring-pressing-off device hereinbefore described and
illustrated with a platform and pins for the purposes ascertained in the foregoing
description.
(6) The combination of a guide, under the control of a former or cam, &
pressure roller and plate, chisel, impalement pins, double platform and pressing-off*
device geared and timed to work together for the purposes hereinbefore ascer-
tained, forming a machine substantially as described and in part illustrated.
