Improvements in Heel Compressing Machines.
I, DANIEL CHARLES BECK, Gentleman, residing at No. 2962, South Jefferson
Avenue, in the City of St. Louis, State of Missouri, U.S.A., 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 improvements in heel compressing machines and it
consists of the novel construction, combination and arrangement of parts, herein-
after described and claimed.
Figure 1 is a side elevation of my improved heel compressing machine. Fig. 2
is a front view thereof. Fig. 3 is a plan view of a rotating disk that carries the
female portions of the dies. Fig. 4 is an enlarged detail sectional view taken
approximately on the line 4-4 of Fig. 2. Fig. 5 is an enlarged vertical sectional
view taken approximately on the line 5-5 of Fig. 1. Fig. 6 is a view of the
under side of the cutter-head made use of in carrying out my invention. Fig. 7
is a plan view of a heel, the same having been compressed in my improved
machine. Fig. 8 is a plan view of the upper forward end of the machine and
showing the vertically operating carriage which carries the male die and the
cutter-head.
In the construction of my machine, a suitable hollow standard 1 projects
upwardly from the base 2, and integral with and projecting laterally from the
front side of the upper end of said standard 1 is a pair of vertically arranged
ears 3, in which is held for vertical movement a block 4. Passing longitudinally
through the center of the block 4 is an aperture 5.
The rear side of the upper end of the standard 1 is provided with a lateral
projection 6 in which is fulcrumed a bell-crank 7, the horizontal portion thereof
extending through the upper end of the standard 1 and into the aperture 5 in
the block 4. The forward end of this horizontal arm is provided with an anti-
friction roller 8, which bears against the top and bottom walls of said aperture 5.
The lower end of the vertical arm of this bell-crank 7 is bifurcated, and pivotally
held in said bifurcated lower end is an arm 9, the lower end of which carries an
anti-friction roller 10. A set-screw passes through an aperture formed through
the rear wall of the lower end of the hell-crank and into the upper end of the
arm 9, and a second set-screw passes through the rear wall of the lower end of
the bell-crank 7 and bears against the rear side of the arm 9. By means of
these set-screws the arm 9 is adjusted backwardly and forwardly.
Located upon the base 2 and to one side of the standard 1 is a pair of alined
standards 11, the upper ends of which are provided with bearings in which is
rotatably arranged a longitudinal shaft 12, and upon said shaft immediately to
the rear of the standard 1 is fixed a disk 13, upon the rear face of the edge of
which disk is arranged at equal distances apart the eccentric lugs 14. The path
of travel of the edge of this disk 13 is in alinement with the center of the
standard 1, and during the rotation of said disk the roller 10 rides upon the
edge of the face of said disk and upon the eccentric lugs 14. An anti-friction
roller 15 is journaled in the standard 1 and bears against the rear side of the
disk 13 immediately opposite the point against which the roller 10 bears.
Fixed upon the shaft 12 a short distance to the rear of the disk 13 is a worm-
wheel 16, the same being driven by a worm 17 that is carried upon the shaft 18,
879

page_text: which shaft is journaled in suitable bearings 19 that are fixed to the base 2. This
shaft 18 is the power shaft, and on one end thereof is fixed a belt-wheel 20 and
upon the opposite end is fixed a grooved pulley 21.
Fixed to the front face of the vertically moving block 4 is a pair of rearwardly
projecting bars 22, on the front of the outer ends of which is fixed a vertically
arranged slotted block 23. Arranged for vertical movement in said slotted
block 23 is a bar 24, the same being vertically adjustable in the slotted block 23
by means of a hand-screw 25 that passes upwardly through the top of the slotted
block 23. Integral with the ends of the bar 24 are laterally projecting arms 26,
in the outer end of which is held for rotation a vertically arranged shaft 27, the
upper end of which is provided with a grooved pulley 28. The lower end of this
shaft 27 carries a circular cutter-head 29, in which is removably located a pair
of downwardly projecting curved kuives 30. Adjustably located in the lower
one of the arms 26 is a vertical rod 31, with the lower end of which is formed
integral a loop 32 that extends laterally to a position immediately beneath the
cutter-head 29.
Fixed to and extending outwardly from the side of the lower end of the block 23
is an arm 33, upon the outer end of which is arranged for rotation a pair of grooved
pulleys 34, the same being in horizontal alinement with the pulley 28. Extending
laterally from the rear side of the projection 6 is an arm 35, upon the outer end of
which is rotatably arranged a pair of grooved pulleys 37, the same being in vertical
alinement with the grooved pulley 21. A belt 38 passes around the grooved
pulley 21, from thence to and over the pulleys 37, from thence forwardly around
the pulleys 34 and finally around the pulley 28. Thus rotary motion is trans-
mitted from the power shaft 18 to the cutter-head 29.
Arranged upon opposite sides of the lower end of the block 4 is a pair of lugs 39,
to which are hinged plates 40, the lower ends of which carry the mating blocks 4.1
that form the male portion of the die of my improved machine. These blocks 41
are provided on their opposite sides with the inclined faces 42, and the inside
of each of said blocks is recessed, as indicated by 43, the combined recesses being
of the form required to give to the heel that is compressed. The upper meeting
corners of the blocks 41 are recessed to receive a head 44, which is carried by a
spring-actuated stem 45 that extends upwardly into the block 4, the spring around
this stem being an expansive coil-spring and acting to throw the blocks 41 out-
wardly when the block 4 is raised.
Projecting forwardly from the center of the standard 1 is an extension 46, to
which is bolted a bearing 47. In said bearing is rotatably arranged a vertical
shaft 48, the same being vertically adjustable by means of the screw 49 passing
through the lower end of the bearing 47. Formed on, or fixed to, the upper end
of the shaft 41 is a disk 50, there being a beveled gear 51° formed integral with
the under side of said disk 50. The top side of this disk 50 is provided with
four circular lugs 51, in which are formed recesses 52 to receive the heels to be
compressed, and which recessed lugs form the female members of the die made
use of in my improved machine. A plurality of points 53 extend upwardly
within the recessed lugs 51, and passing upwardly through the center of said
lugs are the discharge pins or plungers 54. Formed in the edge of the disk 50
immediately opposite the recessed lugs 51 are the notches 55 into which notches
engages the point 56 of the spring bar 57 that is held in a block 58 located upon
the side of the standard 1. By means of this spring-bar and lug, the disk_50
is held in proper position when the male portion of the die is moving downwardly
to compress the heel carried in the female portion of the die.
Rotatably arranged in the top of the outer end of the block 47 is a roller 59
against which the discharge pins or plungers 54 strike during their travel around
with the disk 50.
Rotatably arranged in the bearing 47 is a laterally projecting shaft 61. upon
which is fixed a beveled gear-wheel 62, the same meshing with the beveled gear-
wheel 51 carried by the under side of the disk 50. Formed integral with the

page_text: rear side of this gear-wheel 62 is a ratchet-wheel 63, the same being provided
with four notches, and loosely arranged upon the shaft 61 adjacent this ratchet 63
is an arm 64 which carries a spring-actuated pawl 65, the same engaging in the
notches of the ratchet-wheel 63. Fulcrumed upon the side of the standard 1 is
an arm 66, to the upper end of which is pivotally connected a horizontally arranged
connecting-rod 67, the outer end of said rod being adjustably held to the arm 64.
The lower end of the arm 66 is pivotally connected to a rectangularly bent bar 68,
the same sliding horizontally through a lug 69 projecting laterally from the
standard 1, and the free end of this rectangularly bent bar 68 carries an anti-
friction roller 70 which rides directly upon the edge of the face of the disk 13
and upon the eccentric lugs integral therewith. A retractile coil-spring 71 is
secured to the lower end of the fulcrumed arm 66, and is for the purpose of
returning said arm to its original position after it has been moved.
The operation is as follows:
When power is applied to the shaft 18, the worm 17 thereon will impart rotary
movement to the worm-wheel 16 and shaft 12; consequently, the disk 13 which
carries the eccentric lugs 14 will rotate. Rotary movement is also imparted to
the shaft 27 carrying the cutter-head 29 by means of the belt 38 running over
the various pulleys. As the disk 13 rotates, the eccentric lugs 14 will succes-
sively pass beneath the roller 70, and the rectangularly bent arm 68 which carries
said roller will be moved rearwardly in the direction indicated by the arrow a,
Fig. 1. This movement draws the lower end of the arm 66 rearwardly and
throws the upper end thereof forwardly, and consequently the connecting rod 67
will be moved forwardly and the arm 64 carrying the spring-actuated pawl 65
will be swung approximately one quarter of a revolution upon the shaft 61, and
said spring-actuated pawl 65 will engage in one of the notches in the ratchet-
wheel 63, and said ratchet-wheel and the beveled gear-wheel 62 will be moved
one quarter of a turn. The beveled gear-wheel 62 meshing with the gear-wheel 51*
will necessarily move said gear-wheel 51* a quarter of a turn and the disk 50
carried by said gear-wheel 51ª will move a corresponding distance. The single
tooth 56 carried by the har 57 will engage in one of the notches 55 in the
disk 50, and said disk will be held in position with one of the female dies
immediately beneath the pair of blocks 41 and another one of the female
dies immediately beneath cutter-head 29. The retractile coil-spring 71 causes
the connecting-rod 67, arm 66 and rectangularly bent bar 68 to return to their
normal positions after passing over one of the lugs. The operator of the machine
places the heels to be compressed successively in the open female dies as they
are brought-around by the continued rotation of the disk 50 and are successively
carried beneath the male portion of the die and then to a point beneath the cutter-
head. The lugs 14 after riding beneath the anti-friction wheel 70 pass beneath
the anti-friction wheel 10, and the lower end of the bell-crank 7 is moved out-
wardly, and consequently, the outer end of the horizontal arm of said bell-crank
carrying the block 4 is moved downwardly. Said block 4 moves downwardly
between the ears 3 and necessarily all of the mechanism carried by said block
moves downwardly at the same time. The inclined faces 42 of the block 41
strike against the inclined faces of the recesses in the female die 51 and as a
result thereof the blocks 41 move toward each other as they move downwardly to
compress the heel carried by the female die. At the same time the male die
enters the female die to compress the heel, the loop 32 carried by the rod 31
passes over the compressed heel that is carried in the female die immediately
beneath the cutter-head, and as said cutter-head moves downwardly to its lower-
most limit of movement, any portion of the compressed heel that is too high
will be cut away and removed by the knives 30, and thus all of the heels will be
of the same contour and of the same thickness. When the lug 14 passes from
beneath the roller 10, the bell-crank will reassume its normal position and the
male die and the cutter head will be elevated. During the time said cutter-head
and male die are elevated, the operation of rotating the disk 50 a quarter of a

page_text: turn takes place and the heel just compressed is brought into position beneath
the cutter-head, and the compressed heef that was so operated upon by the knives
of the cutter-head will be discharged from its position in the female die owing
to the elevation of the pin or plunger 54 by the roller 59, as shown in Fig. 4.
The points 53 assist in holding the heel in position within the female die while
said heel is being compressed and while it is being engaged by the knives of the
cutter-head. The cutter-head is adjusted vertically by manipulating the hand-
wheel 35, and the elevation of the disk 50 is adjusted by manipulating the
screw 49.
A heel compressing machine of my improved construction possesses superior
advantages in point of simplicity, durability and general efficiency, requires the
attention of but a single operator, will compress a large number of heels in a
given time and all of said heels will be of the same contour and thickness after
having passed through the machine.
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:-
