In the drawings 1 represents the bed or table of the machine having formed
in one piece therewith or secured thereto the columns 2, 3, 4 and 5 and the
upwardly projecting plate 6.
A stand or bracket comprising the hub 7, the horizontal arm 8, the rearwardly
projecting plate 9 and the grooved plate 10. is mounted by means of the down-
wardly projecting shank or stem 11, in a bearing in the column 2 in such a
manner that it may be moved vertically therein against the tension of the
spring 12, one end of which is secured to said arm 8 and its other end to the eye
bolt 13 adjustably set in the bed 1, by means of the hand lever 14 fulcrumed on
the pin 15, set in the downwardly projecting ears 16, and engaging at its inner
end the lower end of the stem 11, as shown in Figures 2 and 4.
A shaft 17 is mounted in bearings 3 and 4¹ in the upper ends of the columns or
standards 3 and 4, and has mounted thereon between said bearings the cylinder
cam 18 and the cam discs 19 and 20, and upon its end, outside of the bearing 4
the hand or driving wheel 21, the rim of which is grooved to receive a round belt,
not shown, for imparting rotary motion thereto in the direction indicated by
the arrow in Figure 3.
The bed 1 is supported upon legs 22 which are intended to be firmly secured
to a bench or other suitable support, not shown, at a convenient height for
operation:
The grooved plate 10 has fitted therein so as to be movable towards and from
the front side of the machine, the slide 23, having at its front end the upwardly
projecting plate 24 in the front face of which is formed a rectangular groove
extending from top to bottom thereof as shown.
Cap plates 25 are secured to the upper surface of the plate 10 and overlap the
slide 23 and serve to complete the guiding for said slide. The upper surface of
the slide 23 has set therein a pin 26 in such a manner as to be movable about
its axis and is secured in the desired adjusted position by means of the set-
screw 27 shown in Figures 1 and 5. The pin 26 is provided with a collar 28
to rest upon the upper surface of the slide 23, above which projects the eccen-
tric 29, upon which is fitted the rectangular block 30, which is engaged by the
forked end of one arm of the hollow lever 31, fulcrumed upon a pin set in the
upper end of the column 5, and carrying at the end of its other arm a cam truck
fitted to and acted upon by the cam path formed in the periphery of the cylinder
cam 18 as shown in Figure 1.
The path of the cam 18 has two sets of zigzag throws, each set comprising three
throws in each direction, said two sets being separated, upon opposite sides of
said cam, by a standstill each occupying a little less than one quarter of the cir-
cumference of the cam cylinder, as shown in Figure 22.
The groove in the front face of the upwardly projecting plate 24 of the slide 23
has fitted therein, so as to be vertically movable, the two bars or stocks 32 and 33,
provided respectively with the shanks 34 and 35, which project upwardly through
the cap plate 36, and have adjustably fitted upon their threaded upper ends the
stop nufs 37 and 38 respectively, said. shanks 34 and 35 being surrounded,

page_text: between said cap-plate 36 and the upper ends of the rectangular portions of the
stocks 32 and 33, with the coiled springs 39 and 40 respectively, all as shown in
Figures 2, 5 and 6.
The stock 32 has secured to its lower end the cutter 41, the cutting edge of
which extends at right angles to the line of feed and is provided just at the rear
of said cutting edge with an inclined ploughshare-like surface adapted to turn
upwardly the lip of material formed by said cutter in splitting.the edge of the sole.
The stocks 32 and 33 are guided in their upward and downward movements
by the shanks 34 and 35 and the sideplate 42, and the stock 32 has secured thereto
and vertically adjustable thereon, and movable therewith, the pendent arm_43
which carries at its lower end a pressure roll or surface 44 to bear upon the
sole, in front of the cutter 41, said arm 43 being secured to said stock 32, in
its adjusted position, by a clamping screw which passes through a slot in said
arm, and is screwed into said stock, until its head presses hard upon said arm,
said arm being guided in its vertical movements, and prevented from moving
about said clamping screw by a second screw which passes through another slot
in said arm, and is screwed into the plate 42, but without pressing upon said
arm, thus leaving said arm free to be moved up and down with said stock 32,
while it may be adjusted vertically upon said stock by slackening said clamping
screw, moving said arm up or down as desired, and then tightening said screw
again, all as shown in Figures 29 and 30.
The stock 33 has secured to its lower end so as to be adjustable transversely
of said stock, the block 45 having formed in its front face an inclined slot in
which is fitted the cutter 46, which is secured in the desired adjusted position
relative to the cutter 41 by means of the clamping plate 47 and suitable clamping
screws. The block 45 has its inner edge slotted to receive the binding screw 48,
as indicated in Figures 5 and 6:
The stock 33 has secured thereto and vertically adjustable thereon and movable
therewith, in the same manner as the arm 43 is secured to the stock 32, see
Figures 29 and 30, the pendent arm 49 which carries at its lower end a pressure
roll or surface 50, arranged to press upon the sole in front of the cutter 46, said
pressure surfaces 44 and 50 serving to press the sole being operated upon into
firm contact with the sole supporting disc 51 which is mounted and revoluble in
a bearing in the stand 52 secured to the upright plate 6, as shown in Figures 2
and 3.
The stand 52 has pivoted thereto, by its rear end the hand lever 53, the front
end of which rests upon the bracket 54, secured to, and projecting laterally from
the upright plate 6, and having formed in its upper edge two series of holes 55,
and a series of ratchet teeth 56 as shown in Figures 1 and 2.
Two pins 57 and 58 are interchangeably set in the holes 55 to limit the move-
ment of the lever 53 in both directions, and said lever has secured in a fixed
position thereon, the pawl 59, which engages with the ratchet teeth on said
bracket 54 so that the lever may be adjusted to intermediate positions between the
extremes of its movement.
Directly to the right of the centre of the work support 51 the lever 53 has
formed thereon, or secured thereto, the gage 60 which projects over the upper
surface of the sole support to a greater or less distance according to the adjust-
ment of the lever 53, said lever being held in firm contact with the bracket 54
by means of the pawl 59 engaging one or another of the ratchet teeth 56 under
the action of the spring 61, as shown in Figures 2 and 3.
•
The hub of the tool carrying bracket has adjustably set therein the threaded
bushing 62 which is secured in its adjusted position by the set screw 63, see
Figure 1, and has secured therein so as to be movable about its axis the forked
stud 4 in the forked end of which is pivoted the lever 65 to which a vertical vibra-
tion is imparted by the cam path 66 shown in dotted lines in Figure 4, acting
upon a cam truck carried by the lever 67 pivoted at its rear end to the stand 68
and connected at its front end to the link 69, the upper end of which has

page_text: adjustably set therein the screw stud 70 having a ball at its upper end which
is fitted to a socket in said lever at 71.
The extreme right hand end of the lever 65, has adjustably set therein a stud 72
having a ball at its end fitted to a socket in the front end of the link 73, the
rear end of which is pivoted to the upper end of the lever 74 which in turn is
pivoted to the stand 75 secured to the under side of the bed 1, as shown in
Figures 2, 3 and 4.
.
The lever 74 has set therein, near the middle of its length, the stud 76 upon
which is mounted a truck 77 which is acted upon by the path 78 of the cam
disc 20 to impart a lateral vibration to the lever 65 for the purpose of feeding
the sole.
The left hand end of the lever 65 is connected, by a ball and socket joint, to
the upper end of the feed arm 79 the middle portion of which has cut through it
the longitudinal slot 80 to receive the adjustable fulcrum about which said
arm vibrates, and has formed upon its lower end one or more feed points 8.1 which
enter the sole just inside of the channel cutter 41, said feed-points being located,
and movable in the direction to feed the sole in the narrow space between
cutter 41 and pressure roll 44 on one side, and the cutter 46 and the pressure
roll 50 on the other side, as shown in Figures 2 and 23.
The fulcrum pin 82 about which the feed arm vibrates is provided with the
shoulders 83 and 84, as shown in Figure 13, and has fitted thereon, the bushing 85
which bears against the shoulder 83, and has its two opposite sides flattened
so as to fit the vertical slot in the cap plate 86, has loosely fitted thereon the
washer 87 fitted in the slot 88 in lever 89, and also has fitted thereon against
the shoulder 84 the flat sided bushing, 90, the flat sides of which engage the sides
of the vertical slot 91 formed in the plate 9 of the vertically movable tool
carrying bracket, which latter bushing is clamped against the shoulder 84 by the
nut 92, as shown in Figure 9.
The fulcrum pin 82 is prevented from moving about its axis by the flat sides
of the bushing 90 engaging the sides of the slot 91 while it is free to be moved
vertically therein by the vibratory movement of the lever 89 which is pivoted
at 93 Figure 3 to the plate 9.
The pin 82 has loosely mounted thereon outside of the plate 86 the spring 94,
the washer 95 and the cam disc 96 having a flat sided hub 97 which fits into the
slot 80 formed in the feed arm 79 so as to be moved about the axis of said
pin to a limited extent by the vibration of said feed arm.
Another cam disc 98, the inner face of which is a counterpart of the outer face
of the cam disc 96, is firmly secured to the end of said pin 82 by means of the
pins 99, which enter suitable holes in said pin 82, and the clamping screw 100,
so as to be non-revoluble, the office of said cam discs being to cause a slight
inward movement of the lower end of the feed arm as it is vibrated, to insure
the edge of the sole being held in contact with the gage 60, this being accom-
plished by the action of the inclined plane or cam surface 101 on the disc 96
upon a corresponding surface on the disc 98, which causes said disc 96 and the
feed arm 79 to be moved towards the right against the tension of the spring 94,
which forces said arm towards the left, to relieve the pressure on the work,
when the lower end of said feed arm is moving toward the front of the machine,
after having fed the work.
•
A lever 102 is pivoted to the stand 103 secured to the inner surface of the
upright plate 6, and has formed upon or connected with its left hand end a
hammer for setting the upturned lip of the outer channel, which hammer may
be merely a piece of metal having a curved operating surface 104, see Figure 16,
or it may be a roll having its surface curved in the direction of its length as
shown at 105 in Figures 17, 18 and 19.
The lever 102 extends toward the right of Figures 1 and 2 and has adjustably
secured to its right hand arm the grooved block 106 which with said lever 102
extends through a slot 107 in the link 108, the upper end of which has a bearing

page_text: in the stand 109, secured to the hub 7, and the lower end of which is pivoted to
the front end of the lever 110, the rear end of which is pivoted to the stand 111
and carries near the middle of its length a cam truck which is acted upon by the
cam path 112 as shown in Figure 4, to impart to said link 108 a series of rapid
vertical reciprocations to cach revolution of the shaft 17, and a corresponding
series of vibrations of the lever 102.
The upper end of the slot 107 has fitted therein the forked end of the slotted
arm 113 to which the block 106 is adjustably secured by the screw 114, and a block
of leather 115 is inserted in the fork of said arm between it and the
of said slot 107 to act as a cushion to deaden the blow when the link 108 is moved
end
upper
downwards, and the lower end of said slot 107 has set therein the coiled spring
116 the upper end of which rests against the under side of the block 106, and thus
renders the blow given by the hammer 104, a yielding or elastic one.
The lower edge of the block 106 is composed of four different bearing surfaces
for the spring 116 to act against, said surfaces being arranged at different levels
so that by adjusting said block on the lever 102 the blow to be struck by the
hammer may be varied from a heavy to a light blow, or so that no blow will
be struck upon the channel lip of the sole.
In the modified hammer illustrated in Figures 17, 18 and 19, the hammer roll
105 is mounted on a journal set in the forked end of the lever 117 pivoted to the
plate 118 secured to the underside of the plate 10, a spring 119 being interposed
between the plate 118 and the rear end of the lever 117 to normally hold the
hammer roll in a raised position, and the left hand end of the lever 102 rests upon
the lever 117 in front of its connection to the plate 118 and by its vibration
depresses said hammer roll and causes it to strike a blow upon the upturned
lip or channel flap to complete the turning and the setting of the same, the
axis of said roll being at right angles to the length of the rib to be acted upon
or to the line of feed of the work, a stop screw 120 set in said lever 117 forward
of its fulcrum limiting its upward movement as shown in Figure 18.
The feed arm 79 has adjustably secured thereon at its lower end, the cutting
blade 121, the cutting edge of which is oblique to a horizontal plane and at a right
angle to the line of feed of the work, the office of said cutter being to cut in the
upper surface of the sole, from its edge toward its centre, or at right angles to
said edge, a series of incisions, one at each downward movement of the feed arm,
which incisions are formed in advance of the cutting of the channel, or splitting
of the edge of the sole, to form the channel lip e, and said incisions are made to
such a depth, at the outer edge of the sole, that the lip e, when formed by the
action of the channel cutting knife 41, will have its outer edge divided in a series
of sections by said incisions by virtue of which said lip is more easily turned
into the position it occupies in Figure 28, particularly, in the stock portion of the
sole. The cutting blade 121 Figures 3, 8 and 9, is secured to the feed arm by
means of a clamping screw which passes through a slot in its shank, and is
screwed into said feed arm, as shown in Figures 8 and 9, so that it may be
adjusted vertically on said feed arm, to regulate the depth of the incisions cut
thereby in the sole, and said cutter is moved up and down with said feed arm,
to which it is firmly secured.
The operation of my invention is as follows:-
The several parts of the machine being in the positions shown in Figures 1, 2
and 3, the operator first depresses the front end of the lever 14 to raise the tool
carrying bracket, then places the sole to be operated up on the work support
with its heel end towards the rear and its edge against the gage 60, releases the
lever 14, when the reaction of the spring 12 causes the pressure rolls 44 and 50
to press the sole into close contact with the work support.
Now if the wheel 21 be revolved in the direction indicated by the arrow on
Figure 3, the first effect produced is a downward movement of the feed arin
till the feed points 81 enter the sole, through the action of the cam path 66
upon the lever 67, and at the same time the hammer 104 is moved downward to

page_text: strike a blow upon the sole, then the action of the long throw a to b of the cam
path 78 of the disc 20 upon the lever 74 causes the lower end of said feed arm
to be moved towards the rear to feed the sole, during which time that portion
of the path of the cylinder cam 18 between and 4, Figure 22, acting upon the
lever 31 imparts a series of reciprocations to the slide 23, 24, thereby causing the
cutters 41 and 46 to make a corresponding series of reciprocations, each move-
ment towards the front causing a section of two separate channels to be cut,
and the action of the curved or ploughshare surface above the cutter 41 causing
a section of the lip, formed by said cutters splitting the edge of the sole, to be
turned upward into a nearly perpendicular position, the hammer in the mean
time striking several blows to complete the turning and compacting or setting
said lip in its turned position as shown in Figure 28.
The feed arm is then raised and then moved to the front into the position at
starting, at which time the shaft 17 has completed one half of a revolution,
and these motions are repeated during the other half of the revolution of said
shaft, and during each revolution of said shaft two complete cycles of operations
take place as the two halves of each cam are duplicates.
By reference to the last two preceding paragraphs, it will be seen, that the
feed points S1 have imparted thereto four principal movements, viz., a downward
movement, to engage the work, a movement towards the rear, to feed the work;
an upward movement, to release the work therefrom, and a movement towards
the front, to the starting point, preparatory to again engaging the work to
feed it another step, these combined movements constituting what is termed
a four-motion movement, and by reference to the description of the cam discs 96
and 98 hereinbefore given it will be obvious that said feed points have two other
but minor movements imparted thereto by the action of said cam discs and the
spring 94 namely a slight movement towards the right to press the work against
the gage 60, and a movement towards the left to relieve the pressure on the
work, these two movements, combined with the four motion movement herein-
before described, constituting what may be termed a six motion movement.
It will be seen that the movements of the channel cutters are parallel to the
edge of the sole and the cutting action is against the feed movement of the sole,
and that the pressure rolls, which bear upon the sole in close proximity to the
edges of said cutters, move with said cutters and therefore always bear the same
relations thereto.
If a longer or shorter feed is desired the fulcrum pin 82 is moved respectively
up or down in the slots 80 and 91 by means of the lever 89.
In Figure 28 is shown a transverse section of a channelled sole in which c
is the lip formed by the action of the cutter 41, in splitting the edge of the
sole, and is the channel cut by the cutter 45.
