13 ‘Claims. (01. 1-32)
My invention relates to machines for attaching
heels to shoes, it concerning more particularly
the means for‘ presenting a heel-portion, as a
top-lift, to a jacked shoe for attachment.
In heeling shoes, it is sometimes desired to use
bases or top-lifts which have. been prebreasted,
or brought to a condition at the breast-surfaces
at which only a ?nishing operation is required
after attachment... This is advantageous because

turn the base with the shoe angularly, there being
thus produced registration between the breasts of
the base and the lift. The ?nal relation is de
termined by a gaging surface upon the breast GI
bar, in which the inclined surface terminates.
The two work-contacting members of the holder
are preferably both yieldable, as against the ac
tion of springs, the spring for the breast-bar be

been made,thisv depression being caused by the
duction of the heel-portion to the holder, while
the yield of the breast-bar permits the registering

ll When thus operating upon vprebreasted heels, it
is not satisfactory to locate them intheir holders
in the usual manner, by .contact of a ?xed fork
with .therear surface in connection with an, oppo
site, yieldable breast-bar. Differences in the
20 amountspreviously?taken from ‘the breasts will
prevent accurate registration of the top-lift and
base, Gonsequently, it is desirable to locate the
heel-portions, by contact with thebreast, and for
thisv purpose, the breast-bar is commonly ?xed
upon its swing-plate or carrier, while the rear

The yield of the rear member ,
against the lighter spring facilitates the intro
action between the work-portions.
As illus
trated, theyield of the breast-bar is adjustably 15
limited by a connection between it and the car
rier consisting of a series of openings in one and
a cooperating separable pin in the other, there
being clearance between the pin and the open

a jack l0 and a die-block ll carried by a cross
head l2, a shoe S may be clamped for the base
Furthenthe shoe may be turned slightly
about the longitudinal axis of the jack, especially
if a band-clamp.isnotemployed, so the breasts
of the two heel-portions will be out .of registra
tionangularly about such axis. It is an object
of my invention to correct these conditions. For
40 this purpose, the heel-contacting member, as the
breast-bar, which ,is employed to, determine the
position of thetop-liftror other heel-portion, is
arranged to move under the in?uence of the work,
so it may thereby restore the‘, disturbed registra
45 tion longitudinally of the shoe.
The member may
also be. provided with means to change the posi
tion of the work to'produce a further corrective
action. As herein disclosed, the breast-bar of the
top-lift-holder has a surface receiving contact of
50 the work, as of the breast-edge or corner of an
attached base, this surface being inclined out
wardly from the opposite member furnished by
the rearfork. The-forces acting’ and reacting
between thebase'and'breast-bar-surface will be
65 effective to position the bar and, with it, the top
30
cation to a heel-attaching machine such as that
disclosed in Letters Patent of the United States
nailing and top-lift-spanking operations. The
pin [3 of the jack enters the hole in the last L
within the shoe. This support gives some free
dom of movement of the shoe both angularly
about the-axis of the jack and longitudinally of 40
the shoe itself. A swing-plate or like carrier I4
is pivoted at IS on the crosshead for oscillation
by connections l8 to present in operating posi
tion above the die-block either a base-holder b
or a top-lift-holder t. With the holder b, this 45
invention is not especially concerned. It is suf?
cient to say that it receives and locates a heel
base B, presenting it for attachment over the die
block at the beginning of an operating cycle.
The top-lift-holder t has a rear fork 26 pro- 50
vided with a shank 28 guided for reciprocation
upon the plate M in ways 30 in a cover-plate 32. ‘
Opposite the fork is a breast-bar 34, the shank 36
of which is movable in ways 3‘! in the plate 32.
The end of the bar opposite its shank may be 55
2
2,133,372
guided in ways upon the plate l4. At the upper
edge of the breast-bar is a surface 38 inclined
outwardly from the rear fork; that is, downwardly
and inwardly toward a Vertical work-engaging
surface 39 of the bar, in which it terminates.
The fork 26 may be urged toward the breast-bar
into its normal position by a spring 40, shown
as of the torsion type and interposed between the
angular end 4| of the shank 23 and a wall or
10 abutment 42 rising from the plate M. The spring
is retained in place by a rod 44 projecting from
the wall 42.
On the inner end of this rod is
threaded a nut 46, with which the portion 4| of
the fork-shank may contact to adjustably limit
15 the movement of the fork under the in?uence
of the spring 48. The breast-bar 34 is drawn to
ward the fork by a tension-spring 48, joining the
shank 36 near its outer extremity to some one
of a series of openings 50 in the plate l4. By
20 changing the point of attachment of the spring
to the plate, the tension of this spring may be
varied. The force which it exerts to hold the

action, it moving with the bar under the in?uence
of the fork 26 actuated by its spring 40. Before
the ends of the nails protruding from the base
reach the top-lift, the breast-edge of the base
will have arrived at the gaging surface 39. This
determines accurately the coincidence of the
breast-edges of the two heel-portions, so that no
trimming operation upon them will be required.
Having described my invention, what I claim as
new and desire to secure by Letters Patent of the 10
United States is:

ever, have displaced the shoe with its base angu

registration between the breast of the top-lift
and that of the prebreasted heel may be kept
within limits such that the breast-edge of the de
scending base or one of the breast-corners will
70 engage the inclined surface 38 of the bar. The
reaction upon the base will produce a force which
will urge the shoe and base rearwardly and turn
them about the axis of the jack. Simultaneously,
the breast-bar tends to yield under the applied
force, so the top-lift will share in the registering
