such folding and attaching operations speedily
and smoothly, with little effort on the part of
the operator and, when ribbed insoles are being
operated upon, so that the covering shall extend
such surface. There may be, furthermore, a cut
ter in the form of an anvil co-operating with the
knife, and to hold the margin or like portion o-f
the Work clamped to this anvil to receive the
knife-action, I may provide a movable engaging
member. As previously indicated, the surface
over which this engaging member moves may
vary in Width, as does the feather of an insole.
By yíeldably actuating the member, it may be
caused to effect this inward folding and press
the material uniformly against the face of the
anvil regardless of the Width of the feather. The
remainder of the margin is left to be trimmed
by the knife to a definite extent governed by the
0
constant distance the margin is held from the
rib for cutting and by the height of said rib.
Movement of the engaging member, both under
the influence of the spring which provides the
with substantial uniformity to the edge of the
yield and in the opposite direction, is controlled
rib regardless of variations in the Width of the
feather. The invention includes both a machine
and a method in the performance of which said
machine may be utilized.
In the attainment of the above object, there
may be employed, in different combinations, fold
ing, cutting and guiding instrumentalities and a
Work-support, which may be in the form of a
table, with which is preferably associated means
by the movement of the knife. In addition to the
for pressing the covering-material against the
edge of an insole or the like upon the table. The
Work-support or table and the pressing means
may be controlled together by the operator to
place them in positions rendering easy the intro
ed) duction of the Work. The table is preferably ro
tatable to facilitate the feeding or advance of the
Work, and the cooperating sheet-engaging mem
ber applying edge-pressure is yieldable. A Work
gnide is shown herein as entering the outer chan
nel of an insole, it locating the work urged toward
it by the pressure member and directing said
Work in its advance. 'I‘he guide is preferably
movable toward and from the table to clamp the
Work during the non-feeding intervals and to
free it for its forward travel. With the Work lo
~
cutting, folding and clamping movements which
have been outlined, the same elements are actu
ated in another direction, as longitudinally of the
insole-feather and -rib instead of transversely 0
thereof, to advance the work in successive steps.
This feeding movement is produced by mounting
upon a horizontally movable carrier, levers or
other actuating means for the elements. The
feeding of the Work is facilitated by the rotation D
of the table, already mentioned, and by a moven
ment of the edge-pressing member, which is
mounted to oscillate with the carrier. Movement
of the channel-guide toward the table retains the
Work against reverse travel during the return of 40
the feeding elements to their initial positions,

While opposite movement of the guide releases the
Work for feeding.

Herein, the operating elements of the machine
50 appear as movable upon a frame I0 carried by a
base I2, the structure being adapted for mount
ing upon a bench (Fig. 4). Guided for vertical
reciprocation .at the front of the frame in a
bracket I4 is a plunger I 6, upon which is clamped
55 a collar I8. YThis collar, by engagement at‘its
opposite sides with upper and lower surfaces 20
and 22 upon the bracket, limits the extent of
movement of the plunger in opposite directions
(Fig. 6). At its upper end, the plunger has a
60 head 24 in which is an axial bore receiving a
short, depending spindle 26 upon a freely ro
tatable table 28, which table may rest upon bear
ing-balls 30 interposed between it and the head.
The table has an upper horizontal work-support
65 ing surface and is urged upwardly by a spring
32 lying in an axial bore in the plunger I6. This
spring abuts at the bottom against a screw 34
threaded vertically through a plate 36 secured to
the under side of the bracket I4. Variation in the
70 position of the screw allows the force with which
the spring urges the collar against the bracket
surface 20 to be altered. Upon the table the
work is supported for the operations upon it. In
the present instance, the work-piece, as illus
75 _trated in Fig. 14 of the drawings, consists of an
which the spring is chieñy contained. The slide
44 is guided for vertical movement in ways 46 in
a member 41 ñxed to the lower extremity of a
vertical spindle 49 rotatable in the frame at the 25
rear of the table 28. The slide 44 thus fur
nishes an abutment for the spring 40, rising and
falling with the table. A lug rises from the top
of the slide 38, and joined to this for vertical ad
justment by a slot-.and-screw connection 48 is 30
the shank of an edge-pressing member 50. This
member is movable by the slide 38 across the table
in a direction generally radial thereof. At its
side toward which the work approaches, the mem
ber has a vertical extension 52 of substantial 35,
height, curved horizontally in the direction of
work-advance and tapering downwardly to a hori
zontal extension 54 (Fig. 3). As is shown most
clearly in Fig. 6, there is some capacity for ver
tical play between the slide 38 and the head
recess 31 in which it moves.
The under side
of the member 5D may thus shift horizontally up
on the table without binding and yet be compelled
to travel vertically with said table.
Fulcrumed at the front of the co-llar I8 is a bell 45
crank-lever 56, a substantially horizontal arm of
which is held normally raised by a tension-spring
58, connecting it to the head 24 and exerting less
force than the table-spring 32 (Figs. 3 and 5).
The inner end of the lever-arm (Fig. 4) is joined 50
by a rod 6I) to an unillustrated treadle. An up
standing arm of the lever 56 is held in an outward
position and has contacting with it a rod 62 ar
ranged to slide horizontally in the head 24.
Against the opposite end of the rod 62, the slide 55
38 of the pressing member 50 is forced by the
spring 40. Under these conditions, the table 28
is elevated by its spring 32, and the member 5U
is at its inmost point upon the table, both being
in their active positions. When the operator 60
wishes to insert .an insole in the machine for the
operation upon it, he lowers the rod 60. This
ñrst swings the lever 56 about its fulcrum, forc
ing its vertical arm against the rod 62 and press
ing back the slide 38 against the force of its 65
spring 49. This continues until the oscillation
of the lever is stopped by engagement with the
head 24 (Fig. 6), at which time the member 50
has been carried outside the periphery of the table
28. Further downward pull upon the rod 6I) is 70
transmitted to the plunger through the collar
I8, so said collar is lowered against the bracket
surface 22, the spring 32 being compressed. The
member 50 descends with the table under the
influence of the head 24 upon its slide 38. The 75 f.
2,106,268
operator inserts the insole in the machine, slid
ing it over an arcuate rest 6 I, which is secured to
the plunger-head 24 and surrounds' the inner,
rear portion of the table with its upper surface
iiush with that of said table. Then the rod 60
is released, permitting the table to be again ele
vated by its spring and the member 50 to be
moved inwardly over the upper surface of the
table. At this time, the inner vertical face of
10 the presser-extension 52 contacts with the under
side of the marginal portion of the sheet s, turn
ing it up and forcing it against the edge of the
insole-body a.
,
To the upper extremity of the spindle 49 a car
15 rier-arm `|2 is secured for oscillation in a substan
tially horizontal plane. Upon this carrier are
movably mounted the elements which act upon
the work in co-operation with the table, the edge
presser 50 and a channel-guide '|4.
These oper
20 ating elements comprise (Figs. 8, il, and 12) an
anvil 16, a slashing and trimming knife 78, a
folding iinger 80 and a folding and clamping
block 82. At the inner side of the spindle, the car
rier-arm has a counterweight 84 to balance the
25 elements at the opposite side of said spindle. To
all the operating elements upon the carrier is im
parted a movement of translation across the in.
ner side of the table, transversely of the machine
and longitudinally of the insole-feather, to feed

by a cam 86 (Fig. 4) upon a driving shaft 88.
The shaft is journaled horizontally at the rear of
the frame and is rotated continuously through
power applied to its pulley 90. The cam acts
35 upon the lower end of a lever 92 fulcrumed upon
a spindle 93, ñxed in the frame, and joined by a
link 94, variable in length, through universal
joints to: an arm 96 projecting from the carrier
40
(Fig. 1).
The guide '14, between which and the anvil 16
the rib b of the insole is presented over the table
28, is mounted upon a horizontally extending le
ver 98 fulcrumed at |00 upon the frame just be
low the carrier l2. As appears in Figs. 3, '7, and
8, the guide is inclined inwardly and forwardly so
it may readily enter and occupy the channel at
the inner side of the rib b and has a point |02
to lie within the angle of said channel and a
surface |04 against which the layer of fabric c
50 may bear. It is secured to the lever 98 for uni
versal adjustment in a piane intersecting the ta
ble by a clamping screw |06 passing through an
enlarged opening, with which clamping screw
co-operate positioning screws |08, |08.
The anvil 16 is fixed to a depending portion |09
of the carrier 12 by a screw H0, passing with
clearance through an opening to permit adjust
ment. Said anvil has a recess ||2 (Figs. 11 and
12) through which a portion of the knife 18 op
60 erates. The inner edge ||4 of the lower wall of
the recess and the corresponding edge ||6 of the
vertical wall below this recess furnish ledger
55
blades for co-operation with angularly disposed
edges of the knife. The outer wall ||8 of the
65 anvil below the recess is inclined downwardly and
inwardly to generally conform to the angle at
which the insole-rib is disposed. The inner wall
|20 (Fig. 7) is substantially vertical to support
the margin of the sheet s which is pressed against
70 it by the member 32 during the slashing and
trimming operation.
The knife 18 and the folding linger 89 are car
ried upon- a plate |2| secured by a screw |23 to
the lower extremity of a substantially vertical
75 lever |22 fulcrumed at |24 upon the carrier -|2.
3
The knife is attached to the plate | 2| by screws
|26 (Figs. 7, 9, and 10) and has a horizontal
trimming edge |28 and an adjacent vertical
slashing edge |30 (Fig. 13) co-operating, respec
tively, with the anvil-edges ||4 and H6. 'I‘he
openings through which both the screws i23 and
l26 pass are in the form of slots to provide for
universal adjustment of the knife in a vertical
plane. The linger 80 is preferably furnished by
a flat bar, sufficiently thin to yield somewhat in 10
contact with the work, and provided with an en
larged shank |32 through slots in which pass
screws |34 fixing it adjustably in a horizontal di
rection to the plate |2| at the opposite side from
the knife. At the outer extremity of the finger 15
is an upward extension |36, so- outwardly inclined
that it generally conforms to the inner face of
the rib b. At the bottom of the extension |36
where it meets the horizontal portion, the finger
is preferably provided with a projection |38 which 20
rests upon and rubs over the margin of the sheet
s above the feather of the insole, pressing the
sheet against said feather and into the angle of
the outer channel.
Upon the portion |09 of the carrier ‘l2 a bell 25
crank-lever |40 is fulcrumed by a spindle |42.
To a downwardly extending arm of this lever
there is adjustably secured by a Slot-and-screw
connection |44 the folding and clamping block 82.
This block has a vertical, work-engaging face |46 30
(Fig. 7) which co-operates with the face |20 upon
the anvil 'i6 to hold the margin of the sheet s for
cutting and thereafter during the feeding of the
work, as will later be described.
There is a recess
|47 in the member 82 which registers with thel 35
anvil-recess ||2 yduring the cutting and feeding
operation, and through which the portion |28 of
the knife reciprocates. An outwardly extending,
generally horizontal arm of the lever |40 lies
below a contact-roll |48 (Fig. 3) upon a projec
tion |50 from the hub of the lever |22. The ful
crum-sp-indle |42 of the lever |40 is surrounded >by
and connected to a torsion-spring |52, which acts
to force the arm of the lever |40 constantly
against the roll |48.
45
The manner in which the various Work-engag
ing elements are actuated is most clearly shown
in Figs. 1, 3, and 4. Upon the shaft 88 a cam |60
is fixed and causes the oscillation of a lever |62
turning about the spindle 93, this lever having
so
upwardly extending arms |64 and |66. The
longer of these arms, |64, is joined by a substan
tially horizontal link |68, adjustable as to length
and having universal connections, to the lever
|22. The movement thus imparted to said lever 55
|22 carries the knife '|'8 and the finger 80 back
and forth in an approximately horizontal direc
tion to cause cutting and folding actions. To
prevent the knife and its supporting lever from
vibrating during its oscillation and thus failing 60
to properly co-operate with the anvil 76 in >mak
ing its cut, the plate |2| upon which it is mounted
travels at its inner face in contact with a guide
plate |61. This guide-plate has a shank fixed
adjustably by a set-screw |69 to a depending por 65
tion |'|| of the arm l2 (Figs. 4 and 10). The
sliding engagement between the two plates holds
the knife steady for the production cf its cut.
At the extreme forward positions of the knife and
finger and before their movement is reversed, the 70
forward end of the carrier 'l2 swings in a> clock
wise direction (Fig. l), and both act in co-opera
tion with the anvil 'i6 to feed the Work a step for
ward. The arm |66 of the lever |62 is coupled
by a substantially vertical link |10 to the lever 98
4 ,
2,106,268 ïï
through a slot-and-screw connection |12. This
coupling causes the channel-guide 14 to risev and
fall, the relation between the elements. being such

riphery of the insole, and as the cut at the end
of each portion‘d is made by the edge |28 of the
knife 18 before the margin of the sheet s is laid
against the outer face of the ribl b, the different
lengths of the portions d must be determined be
initial position afterthe feeding stroke. During
the forward cutting travel. of `the knife, the roll
10 |48 is lifted, as will be seen upon comparison of
Figs. 6 and e of the drawings. This leaves the
spring §52 free to act upon the clamping member
82, and this is caused to travel somewhat in ad
‘
5
vance of the knife to engage the upstanding mal'
15 gin of the sheet s heid by the. member 50, wipe
it across the feather of the insole and urge it fore the cuts are made. The insole is always lo
against the face H8 of the anvil 16 to be cut by ' cated in a definite radial position upon the table
the knife. 'I'he yieldable action of the member
82 under the influence of its spring |52 causes it
20 to operate uniformly across feathers of different
widths and upon covering-material of different
thicknesses and clears said material from. the
outside the rib and the anvil 16 inside said rib. 20
Outside the wall. |20 of the anvil, the edge of the
insole will extend for different distances, depend
knife as the latter is retracted. When this rear
ward travel of the knife occurs, the lowering of
25 .the roll |48 returns the clamping’member to the
is being performed. This will be evident from an
inspection of Figs. `14 and 15, which show the dif 25
normal position of Fig. 6.
Considering the operation of the apparatus
upon an insole I, the table 28 .is normally raised
and the edge-pressing member 50 is forward, as
30 .appears in Fig. 4. The work-contacting elements
above the table are continuously performing suc
cessive operating cycles. The operator, taking
the insole with its attached sheet s, draws do-wn
the treadle-rod 80, this simultaneously lowering
35 ¿the table and moving back the member 50. The
insole is then introduced over the rest 6| and the
tab-le with the right-hand end of the rib b, as
viewed from the toe-extremity thereof, between
the channel-guide 14 and the anvil 1S. The mar
40 .gin of the sheet s now lies at the inner side |20
of the anvil. Fig. 6 shows the table with the
applied work as rising, and the member 50 about
to move into contact with the margin of the
sheet s to hold it up and force it againstl the edge
45 vof the insole-body a. This occurs upon release of
the rod 80. The folding operation now proceeds
automatically in successive steps until the oppo
site extremity of the rib is reached. As appears
in Fig. S, the point |02 fof the guide 14 lies at the
50' bottom of the inner channel, the rib being held
against it by the upward thrust »of the .table and
the inward force exerted by the member 50. 'I'he
lever |22, under the influence of the cam |60,
swings in with the knife 18 and the ñnger 80,
55 and the block 82, released by the roll .|48 and
urged out by the spring |52, carries the margin
of the cover-sheet across the insole-feather and
clamps it against the anvil-surface ||6 (Fig. 11).
Thus heid, the edge |30 of the knife, co-operating
60 with the anvil-edge | I8, slashes the margin of the
sheet, in a direction substantially perpendicular
to the work-supporting surface Vof the table, to
allow turning up the peripheral excess of mate
rial without fulling, while the knife-edge |28, op
65 erating across the anvil-edge ||4 and acting sub
stantially parallel to the table,.trims off any eX
cess of sheet-margin which would project above
the insole-rib. As these cuts are made, the di
vided portion at d, the entire series of which por
70 :tions may be seen in their final positions in Fig.
1'5, is wiped firmly across the insole-feather by
the spring-'linger 80. The projection |38 of this
finger forces the portion d into the .angle of the
28, with respect tothe termination of the cutting
stroke of the. knife 18, by the channel-guide 14
ing upon which peripheral portion the operation
ference in the width of the feather, and Fig. '1,
illustrating the relation of the machine elements
to the work. As the member 82 wipes in the
margin of the sheet s over the feather, the yield
ing action furnished by the spring |52 allows the 30- '
member to lay upon the feather, up to the bottom.
of the anvil-wall |20, whatever width of sheet
margin may be necessary. This leaves to be add
ed to the length of the sheet-portion d an amount
equal to the thickness of the bottom of the anvil, 35,.
plus the height of the rib. The ñrst of these is
constant, and the second, substantially so. A
proper vertical location of the knife-edge |28 and
its co-operating anvil-edge ||4 will, therefore,
provide for the `correct length of each portion d.
As a result of this, when the cut portion is laid
in place upon the rib, its end will lie approxi
mately at the top of the rib regardless of the
width of the adjacent portion of the feather.
When the knife is within the material, the 45
lever 98, controlled with the lever |22 by the
cam |80,'has lifted the guide 14 from the chan
nel above the lower surface of the anvil (Fig. 4)
relieving the pressure ofthe work against the
table. Now the cam 8B actuates the carrier 12, 50
causing the knife, anvil, block and finger to move
forward together, carrying the work through a
