CEMENTING MACHINE
Herbert E. Edwards, Wellesley, Mass, assignor
to United Shoe Machinery Corporation, Pater
son, N. J., a corporation of New Jersey
Application July 14, 1937, Serial No. 153,611
4 Claims. (Cl. 12—-80)
‘ This invention relates to cementing machines
of the type in which a properly shaped‘ applying
die impresses a spot of cement on a previously
positioned piece of work.
One type of shoe, utilized largely for summer
wear, has an upper which is. composed chiefly of
a plurality of straps, the ends of these straps
being secured between an insole and an outsole.
The lasting of such shoes is greatly facilitated
10 if the operator knows where the ends of the straps
should be placed as they are drawn over the bot~
tom of the insole. It has been suggested, accord
ingly, as is disclosed in an application of H. C.
King, Serial No. 151,877, ?led July 3, 1937, that
prior to the assembling of the shoe, the insole
should be prepared by applying thereto spots of
colored cement in the positions where the ends
of the straps are to be secured. This cement
thereby performs the double function of showing
2.0 ,
the desired position of the straps and of tem
porarily attaching the latter in position where
they can later be permanently attached with
staples or secured by stitching together the in
sole and outsole.
2:5. For the application of spots of cement, ma
' chines of the impression type have been provided,
utilizing an applying die mounted on a swinging
carrier by which the die is moved from a cement
30
pick-up position to a cement-applying position.
With such machines, difficulty has been experi
enced because of the tendency of the die to ap
ply more than the desired quantity of cement and
to squeeze it out or spread it over an area greater
than the desired area, as determined by the out
35 line of the die.
Accordingly, an important object of the inven
tion is to provide an improved cement-applying
machine which will avoid this di?iculty.
A feature of the invention resides in the utiliza
40 tion of a cement-pick-up member with which the
applying die may be contacted and which will
have a slightly smaller contour‘ than that of the
applying die so that when the applying die is
brought into contact with the work, there will
45 be no tendency for it to spread cement beyond
the predetermined outline of the die itself. In
the illustrated machine, the pickup member is
dipped in a cement receptacle and lifted above
the cement as the swinging carrier brings the
50 die into receiving position for contact with said
pick-up member.
These and other features of the invention will
be best understood from a consideration of the
following description, taken in connection with
55 the accompanying drawings, in which
Fig. 1 is a plan view of the machine;
Fig. 2 is a side elevation thereof;
Fig. 3 is a longitudinal section showing the
pick-up member delivering cement to the ap
plying die, and
Fig. 4 is an angular view showing one particular
applying die and an insole which has been coated
thereby.
A machine such as is herein illustrated may
be utilized for applying cement to many different 10'
sorts of work pieces. It will be described herein
as‘ utilized for applying spots i!) (Fig. 4) of colored
cement around the margin of the forepart of’ an
insole l2, shown bottom~side up, which is to be
employed in a strap sandal. The insole will be 15
tacked in the position shown to the bottom of
a last and straps forming the upper of the shoe
drawn around the last will have their end por
tions overlasted on the spots of cement in, these
spots thereby indicating the exact position. de- A
sired for the straps and serving also to hold the
straps temporarily in position. When the ma
chine is utilized for this particular purpose, it
will be provided with a pair of applying dies I 4
having properly shaped applying members 16
which are provided with grooves H3 in order that
they may more readily ‘carry the cement. These
dies are mounted on a backing board 20 having
a spring fastener 22 (Fig. 3) by means of which
the dies may be detachably secured to the cross~ 30'
bars M of a carrier 26.
This carrier 26, having an operating handle
28, is pivotally supported at the upper ends of
four parallel links comprising two forward links
3!] and two rear links 32. These links are pivot 35
ally attached at 34 and 36 (Fig. 2) to the sides of
the frame 40 of the machine which at one end
supports a cement receptacle 42 and at the other
end has a work table 44 recessed to receive a
resilient work-supporting pad 46.
To adapt the machine for use with insoles of
diiferent sizes, the table is provided with a remov
able templet or gage plate 48 (Fig. 1) positioned
on the workv support by jig pins 50. The gage
plate is provided with recesses 52 into which
the insoles may be dropped to hold them tem
porarily in exact cement-receiving position. on
the work table. It will be understood that the
rear ends of these recesses ?t closely around the
foreparts of the insoles.
50
The picking up of cement from the receptacle
and the delivery of it to the applying die 14 is
accomplished by means of a pair of similar pick
up‘members 54 which are, in effect, dies having
plates 56 detachably secured to a perforated grid 55

provided with two similarly shaped lifting devices

The lifting plates 60 are
also provided with laterally extending vertical
?anges ‘H1 which lie in the path of movement of
cam rolls 12 attached to the inner ends of studs
14 (Fig. l) secured to the swinging arms 32.
These studs 14 project through arcuate slots 16
(Fig. 2) in the frame of the machine. As the

It will be noted from Figs. 1 and 8 that these
supplying or pick-up members 54 are of similar
shape to but are slightly smaller in size and
35 contour than the corresponding component mem
bers on the applying die l6 so that cement is only
supplied to the mid portion of the die members
and does not extend all the way to the edges
thereof. When the die carrier 26 is moved back
40 to a position to coat the work, the pick-up mem
bers drop back into the cement in the receptacle
and the applying dies are pressed into engage
ment with the insoles previously positioned in
the recesses of the gage plate 48. It will be
understood that for other sizes of insoles, a gage
plate having differently shaped recesses will be
provided and that the machine will be supplied
with applying dies and pick-up members of cor
responding appropriate shape and size. In view,
however, of the fact that the applying dies may
overlap the edges of the insoles without harm,
one set of dies and pick-up members will suf?ce
for a plurality of sizes of insoles.
Having described my invention, what I claim
as new and desire to secure by Letters Patent of
the United States is:
1. In a cementing machine, a cement-applying
for raising the supplying die above the cement
in the receptacle as the applying die is brought
into contact therewith, said supplying die being
of similar shape to the applying die and of less
size.
4. In a cement-applying machine, a frame
having a cement receptacle at one end and a work
support at the other end, an applying member,
parallel swinging links pivoted on the frame and
supporting said applying member for movement 40
from a position above the receptacle to a posi
tion where the applying member contacts with a
piece of work on the work support, a cement-sup
plying member within the receptacle and pro
vided with a lifting device extending over the
sides of the receptacle, said lifting'device com 45
prising ?xed pins on the frame and inclined sur
faces on the device, said lifting device also hav
ing an abutment, and a member on one of said
swinging links adapted for contact with said
abutment to cause the inclined surfaces of the 50
lifting device to ride up the ?xed pins thereby to
lift the supplying member into contact with the
applying member as the latter is swung over the
receptacle.
