Application January 31, 1936, Serial No. 61,794
In Great Britain March 16, 1935
7 Claims.
This invention relates to lasting machines,
and is herein illustrated as applied to a machine
of the character disclosed in United States Let
ters Patent No. 1,949,539, granted on March 6,
5 1934 upon an application of Joseph Gouldbourn,
Fred Ricks and William T. B. Roberts for lasting
the heel ends of shoes. It is to be understood,
however, that the invention is not limited to ma
chines of that particular character or to heel
10 ‘end-lasting machines.
The machine disclosed in the above-mentioned
Letters Patent is capable of operating upon shoes
of widely different sizes, and for this purpose not
I
only is it provided with means for adjustably
15 varying the limit of movement of the heel-last
ing wipers, but the wipers themselves have de
tachable forward end portions which may be re
moved in operating on shoes of very ‘small sizes.
The wipers, including these detachable end por
20 tions, are provided, moreover, with means for
‘ driving fastenings from them into the shoe
bottom to fasten the upper in lasted position.
(01. 12-—14)
more fastenings than are provided ‘for by the
main portions of the wipers, and in any event
serves to insure against damage to the machine
‘if the operator fails to remove the detachable
end portions when the wipers are adjusted for 5
very small shoes.
'
‘
The above and other features of the invention,
including various novel details of construction
and. combination of parts, will now be more par
ticularly described by reference to the accom- 10
panying drawings and pointed out in the claims.
In the drawings,

wipers constructed in accordance with the pres
ent invention with the wipers shown in fully re- 15
tracted relation to a shoe indicated by dot-and
dash, lines;

as Fig. 3, as viewed in the direction of the arrow
4 on Fig. 1;
Fig. 5 is a perspective view showing in disas
sembled relation parts of the structure shown in
ing pushed forwardly and bulged upwardly in
Figs. 3 and 4;
The wiping edges of the end‘ portions of the
Wipers may be curved inwardly lengthwise of the
5 shoe at their forward ends, so that in the wiping
front of the wipers. If the wiping edges are
30 curved in this manner, there may be danger un
der some conditions that the end portions 08 ‘the
wipers at the opposite sides of the shoe will en
gage each other before the wipers complete their
wiping movements, with resulting damage to the
35 machine.
_
‘
An object of the present invention, among
1 others, is to avoid such danger of damage to a
machine in the operation of end-lasting wipers.
The invention accordingly provides wipers of
40 novel construction having at their forward ends
wiping members which are yieldable laterally of
the shoe relatively to other portions of the wipers.
In the construction herein ‘shown such laterally
yieldable end-wiping members are supported on
45 other end-wiping members which are yieldable
heightwise of the shoe as and for the purpose dis
closed in the previously mentioned Letters Pat
ent, and the laterally yieldable members are fur
ther yieldable heightwise of the shoe with these
50 other members. The use of such laterally yield
able members in a machine of the character dis
closed, for example, in the above-mentioned Let
ters Patent permits the detachable end portions
of the wipers to be left in place in operating on
55 very small ‘shoes in ‘case it is desired to drive

The form of wipers shown in Figs. 1 to 5, in
clusive, comprises wiper blocks I and 3 similar
to the blocks 33 shown in the previously men
tioned Letters Patent, these blocks having de
tachably secured to their forward ends, by screws 50
5 and dowel pins 1, end pieces 9. These end
pieces carry wiping members ll provided with
upwardly extending stems l3 slidingly mounted
in the end pieces, the members ll being pressed
down toward the shoe bottom by springs I5 55

2,082,837
Fig. 4) in the end pieces. Downward movement
of the stem I3 is limited by pins I‘I extending
through the stems and engaging the end pieces.
The wiping members II can thus yield upwardly
in the same manner and for the same purpose as
the members 63, 68 shown in the above-men
tioned Letters Patent. The end pieces 9 and the
wiping members II have in them driver passages
I9 and spring-pressed balls 2| which retain tacks
fed down passages in the end pieces into the
driver passages, as also disclosed in the prior
Letters Patent.
For purposes of this invention each wiping
member II has secured to it a block 25 having a
15 projection 21 (Fig. 5) which enters a recess 29
in the member I I. A screw 3| extending through
a hole 33 in the member II and threaded in the
block 25 holds the block in place. Each wiping
member I I has formed in it a vertical bore 35 in
20 which is rotatably mounted a stem 31 extending
from another wiping member 39. The member
39 and the block 25 have in them cylindrical
recesses 4|, 43 (Fig. l) which receive a spring
45 normally holding a face 41 on the member 39
25 against a stop face 49 on the member II. Each
member 39 has a wiping face 5i (Fig. 5) pro
vided with a rounded work-engaging edge 53
which, when the faces 41, 49 are in engagement
with each other, forms a continuation of a
30 rounded work-engaging edge 55 (Fig. 1) on the
wiping member I I. It will be seen that the edges
53 are also curved inwardly widthwise of the
shoe in directions toward the toe end of the shoe.
Each wiping member 39 has a lip 51 which en
35 gages the upper face 59 (Fig. 4) of the wiping
member II to prevent the member 39 from drop
ping away from the member II and to maintain
the work-engaging faces of the two members in
the same horizontal plane. It will be evident that
40 the two members are yieldable upwardly to
gether against the resistance of the spring I5 in
the wiping operation. Outward yield of each
member 39 against the resistance of the spring
45 is limited by engagement of a lug 6! on the
45 block 25 with the bottom of a recess 63 in the
member 39. The springs 45 are strong enough
to prevent the members 39 from yielding in
wiping over the margin of the upper.
.
The modi?ed construction shown in Figs. 6 to
50 10, inclusive, is associated with wiper blocks
similar to those shown at I and 3 in Fig. 1.
Each of these wiper blocks has secured to it by a
screw and a dowel pin an end piece ‘I9, and each
end piece has'slidingly mounted in it a stem ‘I2
55 extending vertically from a wiping member 14
which is pressed downwardly by a spring ‘I6 in
the end piece. Downward movement of each
member ‘I4 is limited by a pin ‘I8 extending
through the. stem ‘I2 and engaging the end piece
60 ‘I9. The wiping members ‘I4 can thus yield up
wardly in the same manner as the members I I of
the ?rst-described construction. Each end piece
‘I9 and member ‘I4 are provided with driver pas
sages 89 and also with tack-retaining meansv as
65 in the ?rst construction.
Each member ‘I4 has
formed integral with it a block 82 similar in shape
to the detachable block 25 of the ?rst construc
tion, and has within it a vertical bore 84 to re
ceive a vertical stem 86 extending from a wiping
'10 member 88. Each member 88 has therein a re
cess which receives one end of a spring 99 the
other end of which lies in a recess in the block 82.
The spring 99 normally holds a face 92 on the
wiping member 88 against a stop face 94 on the
75 wiping member 14.
The bore in. the block 82 is
so formed that the spring 99 may be inserted after
the wiping member 88 has been assembled with
the member ‘I4, and a pin 95 (Fig. 9) is pro
vided in the block 82 for one end of the spring to
abut against. Each wiping member 88 has a
wiping face 96 provided with a rounded work
engaging edge 98 which, when the faces 92 and
94 are held in engagement with each other by the
spring 99, forms a continuation of a rounded
work-engaging edge I99 on the wiping member 10
‘I4. The edge 98 is also inwardly curved similarly
to the edge 53 in the ?rst-described construction.
The wiping member 88 is prevented from mov
ing downward relatively to the wiping member ‘I4
by a plate I92 which has in it a dovetailed guide
I94 for engagement with a dovetailed guide I96
on the wiping member 88.
The plate I92 is se
cured to the wiping member 88, after the latter
has been assembled with the member ‘I4, by a
screw I98 inserted through a hole H9 in the
plate and into a threaded hole H2 in the mem
ber 88.
A face H3 (Fig. 10) on the plate I92
and a face II4 on the member 88 engage re
spectively upper and lower faces on a projecting
portion H6 of the member ‘I4, and while permit- ‘
ting the member 88 to swing about the axis of
the stem 86 prevent upward and downward
movements of the member 88 relatively to the
member ‘M. It will thus be seen that in the modi
?ed construction the wiping member ‘I4 and the 30
block 82 are formed as a single part, instead of
as two parts, and that there are two parts 88
and I92 instead of a single part.
,
From the foregoing description it will be read
ily understood that if, for operation on a shoe of 35
small size into which it is desired to drive more
tacks than the wiper blocks I and 3 provide for,
these blocks and with them the end pieces 9 or
‘I9 have been so adjusted that in the wiping op
eration the wiping members 39 or 88 come into 40
contact with each other, these members will yield '
against the resistance of the springs 45 or 99
and no damage to the machine will result. Like
wise no damage will result if the operator should
omit to remove the end pieces in operating upon 45
a shoe of small size into which are to be driven
only the number of tacks provided for by the
wiper blocks I and 3.
The laterally yieldable wiping members 39 or
88 have been described as applied to end pieces .50
each provided with two tack driver passages
and with an upwardly yieldable wiping mem
ber II or ‘I4, but it should be understood that
such laterally yieldable wiping members may be
used in conjunction with end pieces each hav— __
ing only one driver passage, or with end pieces "
which do not have upwardly yieldable wiping
members.
It is also to be understood that such
laterally yieldable wiping members may be used
in a construction where there are no detachable
end pieces.
Having described the invention, what we claim
