IMPROVEMENTS IN HEEL MACHINES
Year: 1884

page_text: I, PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane in the County of
Middlesex Fellow of the Institute of Patent Agents do hereby declare the naturo
of the said Invention for IMPROVEMENTS IN HEEL MACHINES to be as follows:-
This Invention relates to improvements upon heel making machines.
The specific features of the Invention include a rotary table carrying the cutting
dies underneath the reciprocating die block an intermittent movement of this rotary
table whereby it is caused to remain at rest while forming the heel and to move so
as to carry the filled die to the discharging point; in placing the movement of this
under the control of the operator, so that the table may be made to move at the
instant the die is filled; the combination of a rotary shifting device for the 'inner
and outer dies; the combination of a cutting die held stationary during the
formation of a heel blank therein with a moveable pasting 'device acting alternately
with the cutting block, a moveable protecting arm or guard; a press combined in
the machine with a cutting mechanism an automatic transferring mechanisin
whereby the heel blank is transferred to the press, and details of construction
whereby these main features are practically embodied in the machine. In the
upper ends of the main frame are slots in which are the ends of the crosshead which
carries a block. These ends project through the sides and are connected by pitmen
to wrist pins on a shaft, which has its bearings in the side pins. A gear wheel on
this shaft meshes with a pinion on the main driving shaft.
This shaft is driven by a pulley through friction gears. The hub of the pulley
being loose on the shaft and rotating constantly. A pinion is fixed on the main
shaft and next the bearing or hub is a bevelled friction wheel, twin to the bevel
face of the pinion. An idle V friction wheel is carried on the rear upturned end of
a treadle lever, and when said lever is depressed, the idle V shaped gear is pressed
between the bevelled edges of this friction wheel and pinion, thus communicating
the motion of the hub to the friction wheel, and to its shaft and causing the cross-
head and block to reciprocate until the pressure is removed from the treadle. The
treadle lever is in two parts fixed to a shaft. An arm on the same shaft carries a
brakeshoe, which bears on a brake wheel on the main shaft. This is so adjusted
ונ1....מ

page_text: in relation to the position of the arm carrying the V shaped idle gear that when
said idle gear is in connection, the brake is off and vice versa. A spring tends
constantly to hold the brake on, and keep the block at rest. A revolving table
turning within a fixerl table or case and enclosed within its cavity is employed;
the flanges of this revolving table are flush with the flanges of the fixed table.
It is carried by a hollow shaft supported in bearings on the frame said shaft being
provided with a bevel gear driven by a second gear on a shaft. This pinion gears
with an elongated pinion loose upon another shaft which receives constant motion
from the main shaft, but communicates its motion to one shaft only when the
elongated pinion is moved longitudinally to bring the clutch parts together. This
is accomplished by means of a clutch and locking levers, the latter being moved by
hand. The clutch is held out of gear by means of a spring and is thrown into
gear by movement inwards of a handle of the locking lever. The clutch lever is
pivoted on a stand, and its forked head embraces the neck of the locking pin.
This pin is placed in a suitable stand and passes through the frame so as to enter
holes in the periphery of the revolving table. These holes in the sides of the table
are placed midway between the position of the cutting dic, so that when the table
is locked, these two dies are on a contral front to rear line.
The same spring which releases the clutch to disconnect the driving power from
the table, forces home the bolt, to lock the table so that both the clutch and the
locking bolt are under the control of the operator, by means of the locking lever.
The table being once started, by means of throwing the clutch into gear and
withdrawal of the bolt, the end of the bolt (preferably hardened) rides on the
periphery of the table and holds the clutch in engagement without further
attention on the part of the operator. When the table has made a half revolution,
the pin drops into its hole, thus permitting the spring to act and release the clutch.
All that is required of the operator to start the machine when the die is filled, is to
give the lever a slight movement towards the machine. When the dies are thus
shifted and the unfilled die is in place, the operator presses down the treadle and
starts the block which may continue in motion till the die is filled. In order to
relieve the operator, a spring detent is provided to hold down the treadle during
the operation described. A roller may be fixed to the periphery of the main wheel
gear which will release the detent upon the arrival of the bar or cross head at its
highest point. In this machine the cutting die does not change its position during
the process of forming a heel blank. The pasting mechanism has been
correspondingly modified. A paste reservoir is located on the top of the machine
frame, a vertical tube leading down therefrom and communicating with, a
horizontal tube on the end of which is a delivery box. The paste is delivered from
the reservoir to this box, which has holes in the bottom for the passage of the
paste to the lift. Continuous with the vertical tube is a shaft stepped in suitable
bearing at its lower end which is provided with a pinion. Into this, meshes the
segment gear of a bell crank lever. Motion is imparted to the bell crank lever by
means of a cam wheel on the upper end of a shaft. The lower end of this shaft
has a bevel gear which meshes into another bevel gear on a shaft. The parts are
so constructed and timed that the horizontal tube will swing to bring the delivery
box over the cutting die, while the block is rising and will swing back to remove
the box from the path of the block when the latter is coming down. A valve in
the bottom of the box is connected to a stem sliding in guides and held to close
the parts by a spring.
When the box has reached its extrome front limit and is directly over the die,.
the valve is open, having been moved by the end of the stem coming in contact
with an adjustable stud on the frame. The .pressure of the column of paste will
be ordinarily sufficient to force it forward, but any ordinary means may be used to
render its discharge more certain. As the paste applying mechanism is driven
from the shaft which directly moves the cross head attachments, it always
maintains its just relation to the block, and applies the paste upon each lift after it
has been cut. In order that the hands of the operator may not be cut or crushed

page_text: by being caught under the block, a guard is provided connected by a spring to a
shaft having its bearing in the cross head. It is rocked by means of a pinion on its
upper end and the segment rack of a bell crank lever. The end of the lever
projects into an inclined slot in a plate on the frame so that the shaft is rocked as
the cross head rises and falls and the arm is thus swung out as the block moves
down and back when it rises. The wood block carried by the crosshead is
attached to it in such a manner that its height may be varied. It is sot directly
into a shell and held therein by means of a threaded bolt.
The shell is connected to a sleeve by means of a bolt and nut.
The sleeve has a flange formed with inclined faces which rest against corresponding
faces on a flange on the cross head.
By loosening the nut, the flange may be turned to adjust the block up or down.
The nut when turned down, holds the parts securely together.
The cutting dies are designed to cut "deck heels," and the inner is raised first
and filled, and then the outer. To reduce the size and facilitate the operation of
the moving parts, rotary for reciprocating inclines are substituted in the die holders.
These die holders occupy the pockets of the revolving table.
The outer die is fixed on a holder formed of an annular plate and a cylindrical
flange. The inner die is fixed upon a similar flanged plate on a sleeve extending
down centrally through the bottom of the tube. Both these flanged die holders
rest on rings or inclined flanges of a circular plate which in turn rests on a plate
which forms the bottom of the structure. A ring attached to the bottom encloses
and guides the holders. A pin set in the inner holder extends through a slot in
the outer holder and the guido, and prevents the holders from turning. The
circular plate is provided with a sleeve which extends below the base of the table,
and has a handle affixed thereto, and extending to the front, so as to be in easy
reach of the operator. The fanges or rims of the plate are formed with reversed
inclines corresponding to those of the holders. All the inclines terminate at their
upper and lower ends. in plain faces, on which they rest. The plate is held by a
pin and is turned back and forth; its turning in one direction causing the inner
die to rise and the outer to fall. Turned in the opposite direction, the motion of
the die is reversed. Within the sleeve of the inner die support is a rod which
projects below the sleeve and carries on its upper end an ejector. This is caused to
operate when the table in turning brings the full die near its rear point when the
lower end of the rod rides upon an incline on the frame and is thereby lifted. The
ejector is preferably of cross shape, but this is not material, an annular plate having
a cylindrical flange is placed in the upper end of the cavity or pocket and rests
upon springs. This forms the plate on which the leather is laid to be cut. The
heel blanks formed by the cutting and pasting in the dies require some additional
pressure in order to render them compact and firm. To do this immediately, while
the paste is still undried, and also to lessen the labour of handling, a press is
combined with the table of the cutting apparatus. In the rear of the machine, and
a little towards one side is a press piston. It works vertically in suitable bearings
in the frame and is operated by toggles, and a bar which is connected by a wrist
pin to a face plate of a shaft. This is driven by means of a pinion from a second
pinion. Thus it is made to operate every time the table moves. It is timed in
its movements to act in proper relation to a conveyor arm, and the movement of
the table.
The press piston bears against a solid die or block above preferably cast with the
frame. In order to prevent the blank from adhering to the press piston a plunger
is provided within the press piston. This plunger is hardened at its lower end
which is bevelled, and bears upon the upper rounded end of the toggle. This is
provided with a hardened steel piece adapted in shape and position to raise
the plunger when the toggle is moved, to lower the press plunger. To the upper
end of the plunger is fixed a steel cross piece which lies in a suitable cavity in the
piston face. At the commencement of the movement of the table which carries the
dies, the toggle joint is moved, the plunger with the steel cross piece is held up,

page_text: when the press piston descends, and is thus held for an instant in contact with
the blank, while the piston is drawn away, and separated from it. A steel spring
returns the plunger to its place. The device for the upper or fixed die consists of
a plunger, and cross piece similar to the clearing device for the press piston below.
It is operated by means of a bent arm and spring which raises the plunger and
holds it up. The plunger is drawn down to clear the blank from the die, by means
of a lever which bears upon a nut on the lower end of the arm. The lever is
operated by means of a pin in a wheel acting on a steel roller on the end of the
lever. The parts are adjusted so that the clearer is brought into action just before
the admission of a new blank to the press, each blank pushing aside its predecessor.
The arm which pushes the blank to the press is pivoted on an offset of the stationary
part of the table, and is thrown and held back by means of a spring. It is thrown
forward when the table has brought the filled die to its rear or discharge position,
and is consequently within the sweep of this arm. The movement is accomplished
by means of pins in the revolving table which are lifted into position to press
against the edge of conveyor arms, by an incline fixed inside of case, over which the
pin moves during the revolution of the revolving table.
It will be observed that the cutting dies may be removed from the cavities in
the table by taking out screws and single dies may be substituted for the double
dies shown in the Drawings. The paster may be taken off and the machine may
be used to cut lifts of any kind, proper dies of course being used for the purpose.
A registering device of ordinary construction may be operated by the pressed
plunger, and register the number of heels formed. Nails may be inserted in the
heel as it is formed of successive lifts in the cutting dic. These nails may be held
with the point upwards in any suitable cavity or holding device in the face of the
plunger within the die; or a nailing dovice of ordinary construction may be located
in the rear of the machine upon the table directly over the position which the die
assumes before the heel blank is discharged.

page_text: It turns within a fixed table or case 01 being enclosed within its cavity and
having its flanges o flush with the flanges o¹ of the fixed table.
Its hollow shaft P. is supported in bearings on the frame, and is provided with
a bevel gear p driven by a gear p', on the shaft q. This pinion gears with an
elongated pinion q³ loose on the shaft (Fig. 5). This shaft receives constant
motion from the main shaft but communicates its motion to q only when q³ is
moved longitudinally to. bring the clutch parts r together. This is accomplished
by means of a clutch and locking levers a and s¹ the latter being moved by hand.
The clutch is held out of gear by means of a spring-1 and is thrown into gear
by movement inwards of a handle of the locking lever &¹. The clutch lever is
pivoted on a stand 2, and its forked head embraces the neck of the locking pin 3.
This pin is placed in a suitable stand, and passed through the frame so as to enter
holes in the periphery of the table O. These holes in the sides of the table are
placed midway between the position of the cutting dio so, that when the table is
locked, these two dies are on a central front to rear line. The same spring 1
which releases the clutch to disconnect the driving power from the table, forces
home the bolt, to lock the table, so that both the clutch and the locking bolt are
under the control of the operator, by means of the locking lever s¹. The table
being once started by means of throwing the clutch into gear and withdrawal of
the bolt, the end of the bolt (preferably hardened) rides on the periphery of tho
table and holds the clutch in engagement without further attention on the part of
the operator. When the table has made a half revolution the pin drops into its
hole, thus permitting the spring 1 to act and release the clutch. All that is
required of the operator to start the machine, when the die is filled, is to give the
lever & a slight movement towards the machine. When the dies are thus shifted,
and the unfilled die is in place, the operator presses down the treadle and starts
the block which may continue in motion till the die is filled. In order to relieve
the operator, a spring detent 30 is provided to hold down the treadle during the
operation described.
A roller may be fixed to the periphery of the main wheel gear releases the
detent upon the arrival of the bar or cross head B at its highest point. In this
machine it will be observed the cutting die does not change its position during
the process of forming a heel blank. The pasting mechanism has been corre-
spondingly modified. The paste reservoir R is located on the top of the machine
frame, A, tube 4 leads down therefrom and communicates with horizontal tube 5
on the end of which is a delivery box 6. The paste is delivered from the reservoir
to this box which has holes in the bottom for the passage of the paste to the lift.
Continuous with the tube 4, is a shaft 9 stepped in suitable bearing at its lower
end which is provided with a pinion 10. Into this meshes the segment gear of a
bell crank lever 11. Motion is imparted to the bell crank lever by means of a
cam wheel 12 on the upper end of a shaft 13.
The lower end of this shaft has a bevel gear 14 which meshes into another bevel
gear 15, on the shaft E. The parts are so constructed and timed that the tube 5
will swing to bring the box 6 over. the cutting die while the block is rising and
will swing back to remove the.box from the path of the block when the latter is
coming down. A valve in the bottom of the box is connected to a stem 7, sliding
in guides and held to close the parts by a spring 16. When the box has reached
its extreme front limit and is directly over the die, the valve is open, having been
moved by the end 8 of the stem coming in contact with an adjustable stud on the
frame. The pressure of the column of paste will be ordinarily sufficient to force it
forward, but auy ordinary means may be used to render its discharge more certain.
As the paste applying mechanism is driven from the shaft which directly moves
the crosshead attachments it always maintains its just relation to the block and
applies the paste upon each lift after it has been cut. In order that the hands of
the operator may not be cut or crushed by being caught under the block a guard 5
18 is provided connected by a spring 20 to a shaft t having its bearing in the cross
head B.. It is rocked by means of a pinion 21 on its upper end and the segment

page_text: rack of a bell crank lever 22. The end of the lever projects into an inclined slot
in a plate on the frame so that the shaft is rocked as the cross head rises and fall,
and the arm is thus swung out as the block moves down and back when it rises.
The wood block C. is attached to the cross bar in such a manner that its height
may be varied.
It is set directly into a shell u and held therein by means of a threaded bolt 23.
The shell is connected to a sleeve w by means of a bolt 24 and nut 25. The
sleeve w, has a flange z formed with inclined faces which rest against corresponding.
faces on a flange y. on the cross head. By loosening the nut 26 the flange & may
be turned to adjust the block up or down. The nut 26 when turned down holds
the parts securely together. The cutting dies are shown in section in Fig. 7.-
They are designed to cut "deck heels" and the inner is raised first and filled and
then the outer.
To reduco the size and facilitate the operation of the moving parts I have
substituted rotary for reciprocating inclines in the die holders. These die holders
occupy the pockets of the revolving table. The outer die 25 is fixed on a holder
formed of an annular plate 26 and a cylindrical flange 27. The inner die is fixed
upon a similar flanged plate 28. on a sleeve 29 extending down centrally through
the bottom of the tube. Both these flanged-die holders rest on, rings or inclined
flanges of a circular plate 29. which in turn rests on a plate 30 which forms the
bottom of the structure. A ring 31 attached to the bottom encloses and guides the
holders. A pin 32 set in the inner holder extends through a slot in the outer
holder, and the guide and prevents the holders from turning.
The plate 291 is provided with a sleeve 33 which extends below the base of the
table and has a handle affixed thereto and extending to the front, so as to be in
easy reach of the operator.
The flanges or rims of the plate 29 are formed with reversed inclines corre-
sponding to those of the bolders. These inclines are shown in part in the dotted
and full lines 34-34 of Fig. 7.
All the inclines terminate at their upper and lower ends in plain faces on which
they rest. The plate 30 is held by a pin 35. The plate 29 is turned back and
forth and as it turns in one direction causes the inner die to rise and the outer
to fall.
Turned in the opposite direction, the motion of the die is reversed. Within the
sleeve of the inner die support is a rod 37 which projects below the sleeve and
carries on its upper end an ejector 38. This is caused to operate when the table in
turning brings the full die near its rear point-when the lower end of the rod rides
upon an incline 42 on the frame and is thereby lifted. The ejector 38 is preferably
of cross shape but this is not material. An annular plate 39 having a cylindrical
flange 40 is placed in the upper end of the cavity or pocket and rests upon
springs 41-41. This forms the plate on which the leather is laid to be cut. The
beel blanks formed by the cutting and pasting, in the dies require some additional
pressure in order to render them compact and firm.
To do this immediately while the paste is still undried and also to lessen the
labor of handling. I have combined a press with the table of the cutting apparatus.
In the rear of the machine, and a little towards one side is the press piston S.
It works vertically in suitable bearings in the frame and is operated by the
toggles 49, 50 and the bar 51, which is connected by a wrist pin to a face plate of
the shaft 54. This is driven by means of pinion 53 from the pinion q'. Thus it
is made to operate every time the table moves. It is timed in its movements to
act in proper relation to the conveyor arm 55 and the movement of the table.
The press piston bears against a solid die or block 61 above preferably cast with
the frame Fig. 8. In order to prevent the blank from adhering to the press piston
I provide a plunger 62 within the press piston S. The plunger 62 is hardened at
its lower end which is bevelled, as shown in Fig. 9 and bears upon the upper
rounded end of the toggle.

page_text: This is provided with a hardened steel piece 66 adapted in shape and position to
raise the plunger when the toggle is moved to lower the press plunger.
To the upper end of the plunger is fixed a steel cross piece 70 which lies in
a suitable cavity in the piston face. At the commencement of the movement of
the table which carries the dies, the toggle joint is moved the plunger with the
steel cross piece is held up, when the press pistou descends, and is thus held for
an instant in contact with the blank while the piston is drawn away and separated:
from it.
A steel spring 65 returns the plunger to its place Fig. 8 shows the device for the
upper or fixed die. It consists of a plunger 70 and cross piece similar to the
clearing device for the press piston below.
It is operated by means of a bent arm 69. and spring 71. which raises tho
plunger and holds it up. The plunger is drawn down to clear the blank from the
die by means of a lever 68 which bears upon a nut on the lower end of the arm 69.
The lever is operated by means of a pin 67. in wheel 54 acting on a steel
roller on the end of the lever. The parts are adjusted so that the clearer is brought
into action just before the admission of a new blank to the press, each blank
pushing aside its predecessor. The arm which pushes the blank to the press is
pivoted on an offset of the stationary part of the table and is thrown and held back
in the position shown in Fig. 3. by means of a spring 56 shown in Figs. 4 aud 8.
It is thrown forward when the table has brought the filled die to its rear or
discharge position and is consequently within the sweep of this arm.
movement is accomplished by means of pins 60 in the revolving table which are
lifted into position to press against the edge of conveyor arms 55 by an inclino (not
shown) fixed inside of case O¹ over which the pin moves during the revolution of
the revolving table O.
The
It will be observed that the cutting dies may be removed from the cavities in
the table by taking out screws 60 and single dies may be substituted for the double
dies shown in the Drawings.
The paster may be taken off and the machine may be used to cut lifts of any
kind proper dies of course being used for the purpose. A registering device of
ordinary construction is indicated at x. It may be operated by the pressed plunger.
and register the number of heels formed.
Nails may be inserted in the heel as it is formed of successive lifts in the cutting
die. These nails may be held with the point upward in any suitable cavity or
holding device in the face of the plunger within the die or a nailing device of
ordinary construction may be located in the rear of the machine upon the table
directly over the position which the die assumes before the heel blank is discharged.
