Improvements in Boot-heeling Machinery.
I FRANKLIN JACKSON of Victoria Works, Kettering, Northamptonshire, 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:-
This invention relates to improvements in machines for attaching and "top-
piecing" the heels to the uppers of boots and shoes, and to the breasting of the same,
the object being to simplify and render more efficient this class of machine.
In carrying out this invention, upon the table of the machine is arranged a turn
plate provided with two die stands and heel moulds, one for attaching, the other for
top piecing. These stands have dies in which are holes to receive the nails, and a
driving head fitted with punches in the usual well known manner. The driving head
of the top piecing stand has a breasting knife secured to it by screws, so that the
knife can slide upon it, and its height be adjusted by a screw so placed as to carry it
up simultaneously with the driving of the top piece nails. As desired, one or other
of the heel moulds are brought over a plunger fitted in the table of the machine, by
swivelling the turn plate, and the mould will then be immediately under the jack or
horn of the press. This jack, on which the boot to be heeled is placed, is pendent
from an upper crosshead coupled with a lower crosshead below the table, by rods
fitted to slide in guideways formed in the side frames of the machine. The lower
crosshead carries pendent arms which embrace a cam on the cam shaft, and are pro-
vided with bowls which enter grooves on the faces of the cam. A peripherical steel-
faced incline on this cam, underlies the lower end of the nail driving plunger, and the
respective position of the grooves in the cam, and the incline on its periphery, are
arranged so that the eccentric grooves in the cain shall draw down the jack or horn,
carrying the upper of the boot or shoe, and hold it clamped upon the heel in the
mould, before the incline upon its periphery strikes the plunger, which is to act upon
the driving head in the mould, and force up the attaching nails through the heel
placed in the mould.
For intermittently driving the cam shaft, an arm is provided fast upon the cam
shaft, carrying at its outer end a trip catch lever for taking into the teeth of a ratchet
formed on the boss of a spur wheel, mounted loosely on the cam shaft. This spur
wheel is geared with a spur pinion on the main shaft, and is kept constantly running.
A tappet operated by a hand lever, or by a treadle, is moved out of or into the path
of the tail of the trip lever, thereby allowing the trip lever to interlock with the
ratchet teeth, or disengaged therefrom, as required. The interlocking of the trip
lever causes the descent of the horn or jack, the clamping of the upper on the heel in
the mould, and the striking of the incline to raise the plunger and drive the nails
while the upper and sole of the boot are rigidly held to the heel to be attached or top
pieced. The raising of the plunger and driving head will carry with it the breasting
knife, which is adjustable as to the depth of its cut.
In the accompanying drawings,
Fig. 1 is a front elevation of a press constructed according to my invention.
Fig. 2 is a sectional elevation, and
Fig. 3 shews, on an enlarged scale, and in section, the arrangement of the cam.
A A are standards carrying a horizontal table B, on which is mounted the turning
plate C, carrying two die stands C1 C2, which are to be employed, the one for
attaching heels to the uppers of boots and shoes, and the other when top piecing the
heels. DD are bars fitted to slide in vertical guides formed to receive them in the
inner faces of the standards A A, and they are connected together by cross heads E E¹
above and below the table B. The upper cross head E carries an adjustable born or
plunger F, for receiving the upper of the boot or shoe, and the lower crosshead E¹ has

page_text: two pendent arms e carrying bowls e', which enter face grooves formed in a cam G.
This cam is keyed on the shaft H, which is driven by gearing, such as spur pinion i
and wheel h, from the main driving shaft 1.
J is a trip catch lever carried by an arm J', which is keyed upon the shaft H, and
this trip lever J takes into ratchet teeth formed on the boss of the spur wheel h.
When engaged with the teeth on the boss of the wheel h, the trip lever permits of the
movement of rotation of the wheel i being communicated to the shaft H and cam G
keyed thereon.
K is a tappet incline carried at one end of a rod K', which can be operated by
means of the handlever K2 on the other end, or by a treadle so as to throw the
incline K into the path of the trip catch lever J, whereby the trip lever will be raised
as it comes round. By the disengagement of the trip lever, the rotation of the cam
shaft H will cease, and the action of the machine will be arrested until the trip lever
again falls onto the teeth of the ratchet, by the removal of the tappet incline. A
coiled spring applied to an arm on the rod K¹ will keep the incline out of action
until the machine is again required to be set in motion.
Lis a plunger fitted to slide freely up and down through the table B of the
machine, and carrying at its lower end a bowl l. This bowl will constantly bear on
the periphery of the cam G, which is fitted with a steel faced incline or boss M. The
heel stands CC2 are carried by the turn plate C, so as to be capable of being brought
under the horn or plunger F, carrying the upper to be attached. These heel stands
carry dies in which the attaching nails are placed, and each is provided with a driving
head C, for forcing the nails simultaneously into the heel of the boot. The plunger L
carries an adjusting screw at its upper end, by which the amount of motion to be
transmitted to the driving head of the nailing mechanism carried by the heel
stands C1 C2, may be regulated. The die in the heel stands C for receiving the
attaching nails is of the usual construction. The die C³ carried by the top piecing
heel stand 3, in addition is provided with a breasting knife c, which is fitted to the
mail die, so as to be capable of sliding thereon. The lower edge of the knife has a
projection c¹, which overlies, an adjusting screw c2 carried by the driving head (4,
fitted to the heel stand 02.
The operation of attaching heels will be effected in the following manner :-
:-The
plate C is turned to bring the heel stand C₁ under the horn F, and the upper is placed
on the horn F; nails are then placed in the die holes of the stand (with suitable
heel lifts thereon); the tappet incline K is then thrown aside by the handle K³, so as
to release the trip lever J, which will fall onto the boss of the wheel h, and interlock
with the ratchet teeth, whereby the shaft H and cam G will be driven.
During part of the rotation of the cam G, the face grooves will cause the descent
of the horn, and press the seat of the upper onto the heel of the stand. By this time
the bowls will be in the concentric part of the grooves, and the horn will hold the
upper firmly down on the heel lifts. The steel faced incline M will then strike the
bowl on the lower end of the plunger L, and drive it up. In its turn, this plunger L
will act on the driving-head in the die stand, and drive up the nails into the heel.
The concentric part of the grooves having now passed the bowl f, the horn will be
raised, and the attached heel be lifted out of the stand. On the rotation of the cam
being completed, the tail of the trip lever J will be brought against the incline K,
and tilted so as to disengage itself from the ratchet teeth of the wheel h, and the
rotation of the cam will cease. The horn being stopped in its highest position, the
plate C may be turned, and the heeled boot may be brought down upon the stand C2,
for top piecing the heel, the die being previously furnished with nails and a top lift.
During the attachment of the top lift, the knife c will shear off the breasts of the heel,
and complete the operation of heeling.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a boot heeling machine. the use of a single cam for performing the operation

page_text: of drawing down & holding the horn, and for driving the nails into the heel, as set
forth.
2. The machine for heeling boots and shoes constructed substantially as herein
shewn and described.
