Improvements in Machines for Forming Heel Stiffeners.
1, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 :-
This invention relates to machines for forming heel stiffeners and is an improve-
ment upon the invention described in the Letters Patent Nos. 13776 of 1890 and
4293 of 1891, and it consists in certain novel features of construction, arrangement
and combination of parts, as hereinafter described.

In the drawings A is the main frame of the head of the machine supported on
the column B, only a small portion of which is shown, said frame having mounted
in suitable bearings thereon the horizontal shafts C, D, E, and F.
Gand Gare the tight and loose pulleys on the shaft C; a b c and d are spur
gear wheels connecting said shafts; e and the fluted rolls for corrugating that
portion of the counter blank from which the flange or heel seat of the stiffener is
to be formed, said rolls being connected together by the spur gears g h and have
motion imparted thereto by the mitre gear wheels i and j.
Hand Hare respectively the former and mould for performing the second
operation upon the blank, of imparting thereto curves both longitudinally and
transversely. I and I are respectively a revoluble disc and an adjustable mould
for performing the third operation, or the reshaping of the centre or rear portion of
the partially formed or "clam shell counter stiffener."
is the table for supporting the moulds and former for reshaping the sides of
the stiffener, firmly bolted to the column B and having mounted in pendent
bearings thereon the horizontally reciprocating rod T to which motion is imparted
by the crank pin k set in the crank disc K secured on a short shaft mounted in a
bearing in the hub J projecting horizontally from the foot or flange J of said
table J, said shaft having secured upon its other end the gear wheel d¹, which
engages with and has motion imparted thereto from the gear wheel d.
The rod T is provided with the notch in its underside with which the latch

page_text: lever q engages to lock said rod to the bracket or arm R fitted to said rod and to a
bearing in the slot in the table and carrying at its upper end the flange
turner S.
So far the several parts are constructed, arranged, and operated substantially as
described in the before cited Patents, except in some few matters of detail, which
will be hereinafter explained.
In the machines described in said prior Patents before cited, when it was
necessary to change the spheroidal former and its mould or socket for one of a
different size the two caps to the bearings of the former shaft had to be removed.so
that the shaft and the former fixed thereon could be removed to permit the mould
to be removed.
This was found to be objectionable on account of the time lost in making the
change.
To obviate this objection there is mounted in bearings in the frame A. the sleeve
shaft having formed therein a bearing for the shaft E so constructeil, and the
shaft E so fitted thereto that said shaft and the sleeve must revolve together,
and at the same time the shaft E may be adjustable endwise in its bearing in said
sleeve to vary the position of the spheroidal former relative to its socket.
In the machine illustrated this is accomplished by making a portion of the inner
end of the shaft E square as shown at E2 and forming a portion of. the bore of the
sleeve E¹ of a corresponding shape, and securing the shaft E in the desired position.
in said sleeve by means of the set screw which passes through the hub of the
gear c, fast on the sleeve E', and through said sleeve as shown in Figure 8.
The left, or outer end of the shaft E has formed thereon a head e' which fits
into a counter-bore in the former H and the shaft has set in its side a short distance
to the right of said head the stud e².
The former H has a hole through it to fit the shaft E at its headed end, and
has formed in its inner wall the L-shaped groove e³ as seen in Figure 12 into
which the studenters as the former is moved towards the head e¹ and locks it in
position when said former is turned so as to bring the stud into the circum-
ferential portion of said groove.
By this construction of the shaft E, sleeve E' and former H, the former and
mould H can be very readily and easily removed and replaced, by simply turning
qut the set screw H³ and pushing back the mould H to the position shown in
Figure S, turning the former on the shaft E until the stud is in line with the
longitudinal portion of the groove e³, then loosen the set screw m when the shaft E
may be withdrawn from its sleeve and from the former, and then the mould'H' can
be readily removed from its socket H. This is an important feature of this
invention and is of great advantage.
The side shaping moulds 00 are mounted upon studs set in the pistons N,
which pistons are pressed towards each otlier by the rubber springs Q Q sub-
stantially as shown and described in the before cited prior Patents.
In the present invention however the tensions of the springs Q Q are adjustable
by means of the tension bolt which passes through the centres of the pistons N
the springs Q and the followers N' N and is provided with the wheel nut N2, as
shown in Figure 4.
The inner ends of the pistons N are bevelled to form a suitable surface for the
stop wedge N to engage with to limit the inward movement of said pistons said
wedge being constructed and arranged to be forced inward to a greater or less
distance from the centres of said pistons, by the action thereon of the eccentric O'
as shown in Figures 5 and 6.
The inner ends of the moulds O O have mounted therein the forked studs n' n¹
cach carrying in its forked end an anti-friction roll 2 against which a suitable
surface on the outer sides of the two parts of the divided former P near their
inner ends bears, said rolls and studs being adjustable towards and from said
formers by means of the set screws n³ as shown in Figures 3, 4 and 7.

page_text: "
The roll is kept in contact with the former by the tension of the spring
mounted upon the curved rod of fixed at one end in a hole in said mould O, and
resting at its other end in an open slot in the movable end of the plate of the slotted
end of which is turned at right angles to its main body, and the opposite end of
which is pivoted to the plate o secured to the piston N, the spring o being com-
pressed between the shoulder of the mould O and the upturned slotted portion of
the plate o and the rod of being provided in its outer end with the pin o³ to serve
as a stop to limit the inward movement of the inner end of the mould, all as shown
in Figures 1, 3 and 7.
In the prior Patent No. 4293 of 1891, the moulds O were provided with lips to
project under the former to turn the side portions of the flange or heel seat of the
stiffener, and a notched reciprocating plate was used to turn the central portion of
said flange or heel seat, and, in order to allow the requisite motion, to be given to
said plate when the moulds were clamping the stiffener between them and the
former, a portion of the lip on each mould had to be cut away.
This was found to be objectionable on account of the said lips being thus made
too short so that they did not turn the side portions of the flange sufficiently near
to the heel end of the former.
This objection is obviated in the present invention by pivoting to the under side
of each of said moulds the segmental plate p fitted to fill or partially fill the space
formed by cutting away the lip said plate being normally held in the position
shown in Figure 7 by the tension of the spring thus forming an extension of the
shortened lipe and at the same time said plate is movable about its pivot by the
forward or inward movement of the notched flange turning plate S, and limited in
its outward movement by the stop più p³ coming in contact with the end of the
slot as shown in Figure 7.
In the said prior Patent the flange turning plate S was secured in a fixed position
on the arm R which was fitted to be reciprocated in the slot by the rod T. to
which it was connected by the latch lever 7, which was located above said rod T
and was moved into engagement with the notch by means of a treadle on the
floor, and was disengaged by a spring, said rod T being provided with a vertical
slot into which projected a crank-pin by which said rod and flange turner were
reciprocated.
In the present invention the notched flange turning plate S has its under side
slightly inclined and roughened or serrated, and has inserted beneath it the corre-
spondingly tapered plate S the upper surface of which is also roughened or serrated,
said plates S and S being secured to the upper end of the arm R by the bolts »
said plate S being slotted so that it may be adjusted endwise beneath the plate S,
in such a manner as to raise or lower said plate S to adapt it to different thicknesses
of stock.
The latch lever, instead of being placed above the rod T, is placed below it.
and has adjustably pivoted and clamped to its movable end the segmental arm
which the operator touches with his knee to cause said lever to engage the notch /
in the rod T, the force of gravity disengaging said lever from said notch, when the
pressure of the knee is removed."
Instead of making the slot T vertical or at right angles to the axis of the
rod T as in the last mentioned prior Patent, said slot is made curved with its
central portion having a radius at its centre line equal to the radius of the crank K
as shown in Figure 5 whereby the rod T, when at the extreme of its outward
movement, has a stand still or rest during nearly one quarter of the revolution of
the crank K, during which time the latch lever 7 may be engaged with, or dis-
engaged from, the notch, with certainty.
The curved arm 2 clamped to the inovable end of the latch lever may be
adjusted about its pivotal connection to the said lever to raise or lower the under
side thereof to adapt it to the height of the operator's knee.
The former is made in two equal halves; divided longitudinally, as described

page_text: in said prior Patents, but instead of the two parts being hinged together at a point
somewhat removed from the heel end of the former about which point the said two
parts vibrate, and having their heel ends bevelled on their inner faces to permit
said vibration as in said prior Patents, longitudinal recesses are formed in the
inner faces of the two parts of the former P, in which are secured by screws or
rivets the springs the opposite end of each spring having formed therein an
eye to fit on the studs set in the table said spring serving to prevent any endwise
movement of the former and at the same time permit the two parts thereof to
vibrate about a point at the extreme heel end of the former as represented by
the semi-cylindrical rib or lip s', on one part of the former, which fits into a
correspondingly shaped recess in the other part, as clearly shown in Figures
and 7.
A stud is set in the table), and projects upward therefrom between the two
parts of the former P, and has fitted thereon the cross-bar t' and the wheel nut
for the purpose of preventing the former from being lifted by the action of the
lipse on the moulds, in turning the flange under said former.
The inner ends of the two parts of the former P have mounted therein the anti-
friction rolls u in position to be acted upon by the cam U, in forcing said inner
ends outward or away from each other.
V is a spring plate attached to the table J at its inner end by rivets or screws
and extending beyond the heel end of the former P and has pivoted to cars on its
under side near its outer end the connecting rod u², the lower end of which is fitted
to the crank-pin us carried by the shaft provided on its other end with the milled
wheel V by means of which the outer end of said plate may be adjusted to a higher
or lower level to gauge the width of flange to be turned on the stiffener, all as
shown in Figures 5 and 10.
The shaft E and sleeve may be fitted together so as to be revoluble and the
shaft movable endwise in said sleeve in other ways than that shown, as for instance.
the bore of the sleeve may be cylindrical its entire length, and a short key, or pin
may be set therein so as to project into said bore and the shaft may be cylindrical
throughout its length, except that it may have a longitudinal groove or keyway
formed therein, into which the key, gib or pin enters to insure the rotation of th
shaft with said sleeve.
The notched flange turner S will be moved outward by the action of the spring
mounted on the rod a fixed at one end in a pendent part of the table J and having
a bearing at its other end in an eye set in the arm R as shown in Figure 2.
