page_text: springs o coiled about stems p extending from the boxes and confined endwise
between the upper surfaces of the boxes and the upper end of the stands.
The object of these pressure rolls is to keep the lower section of the feed belts
tightly in contact with the cans.
J Jare other and larger pressure rolls supported in standards K and yieldingly
held down by springs shown in Fig. 7 in a similar manner to the rolls before
described. The pressure exerted by these last named rolls is greater than that
exerted by the others, and they are therefore made of a larger diameter in order
that they will be easily revolved by the feed belts.
L L are guide rails supported by laterally extending stems q which extend
therefrom and pass loosely through the standards B and H; and they together
with the rails, are adjustable laterally by means of springs r coiled about the stems,
and thumb nuts s. As the nuts are unscrewed, the spiral springs carry the guide
rails inward and the springs are compressed as the nuts are screwed up. By
these devices, the rails may be set to suit the length of the cans to be labeled.
M is a tray for holding cement, situated below the frame A which is cut out to
form an opening of the size of the tray, and near the entrance end of the machine.
The cement used in this tray has to be melted or reduced to nearly a liquid
state, and to effect this, a lamp N of any appropriate description, is placed under
the tray and supported by a shelf ( bolted to the legs a.
Extending through the tray M is a shaft P driven from the shaft b by means
of the pulleys Q and R and the belt S.
TT are disks on the shaft P, see Fig. 3, partially immersed in the cement
in the tray. The circumference of these disks is about flush with the surface of
the frame, and the disks are preferably grooved at their edge to better hold
cement.
Between the discs T is a spring plate t which by deflection allows the cans to pass
under the feed belts when the cans are directly under the shaft b. In other words,
the spring plate t constitutes a yielding bed for the cans
as the same are
delivered to the frame at the entrance end of the machine.
U is an opening in the frame in which is situated a label holder V. This device
consists of a plate on the head of the vertically moving stem v adapted to slide
in a sleeve a supported by a stationary plate 4 bolted to the legs a below the
frame A. The stem v projects below the sleeve a¹ and to its ends is connected a
strap which passes over and is secured to the circumference of a wheel d' on
the shafte which turns in brackets f¹ dependant from the under side of the
stationary plate b¹.
W is a spring coiled about the shaft e¹ with one end thereof attached to one of
the brackets f¹ and the other end to the wheel
.
Before the strap c! is connected to the end of the stem v, the wheel d' is turned
and the strap wound thereon, consequently the label plate u has always a ten-
dency to rise or resist depression. Labels placed on the plate U are therefore
held against the underside of the sharpened pins g' which keep the top label in
alignment or flush with the upper surface of the frame A
As a preliminary step to placing a stack or bunch of labels on the plate U,
the said plate is pushed down to its lowest position where it is held by a weighted
pawl the point of which enters a notch in the stem.
When the bunch of labels is properly arranged, the weighted pawl h¹ is tripped,
and the upper label is thereby brought into contact with the sharpened pins gl
before mentioned.
A¹ is a paste pot supported from the side of the frame A, containing a wheel B¹
on a shaft C₁.
A wheel D¹ coresponding in size with the one B' is on a shaft E¹ supported in
boxes one of which is on the bracket I and the other on the stand F which
stand together with a similar stand on the other side of the pawl is employed to
sustain a shaft G₁ hereinafter described.
The wheels B¹ and D¹ are connected by a belt H¹ the lower section of which

page_text: is elevated somewhat above the bed and traverses, crosswise, the upper label of
the bunch at a point near to its rear end, and when depressed applies paste
thereto.

In order to effect the movement of the belt H¹ the shaft G¹ is provided with a
star wheel I situated in the path of the moving cans, which as a can comes in
contact with it, is turned one fourth of a revolution.
The rotary movement of the shaft G', is transmitted to the shaft E¹ through the
medium of the spiral gear wheels and or by any other power transmitting
devices adapted for the purpose, and the relative positions of the star wheel and
the pasting belt is such that the latter is at rest as a' can passes over and de-
presses its lower section.

The belt His prevented from running off the wheel B' by means of a guide m¹,
and the surplus paste is scraped from the outer surface of the belt by a scraper n¹
on the top of the paste pot.
The lower section of the pasting belt as before stated is somewhat above the
surface of the top label; and is pressed down on to the label directly by the can
in its passage over it. In other words, as a can rolls over the lower section of the
belt, the same is pressed down on to the upper label for a moment and applies
paste thereto, the portion of the label pasted having a width corresponding to
the width of the belt and a length which is practically the same as the length
of the can.

The bunch of labels is guided at the side and at one end by the adjustable
plates o¹ one of which has downwardly extending bars of a length slightly
greater than the depth of the bunch, and a 'stand q' which is seated on the sta-
tionary plate b¹.
The sharpened pins g₁ before referred to, project inward from these plates and
are adjustable in length to lap over the lateral edges of the labels.
K is a rod situated in front of the pasting belt H¹, and resting on the top
label. The object of this rod is to distribute the paste applied by the belt to the
label near its edge, to its extremity, and also to hold the label tight while it is
being drawn around the can. It also serves to give an inward curve to the pasted
end of the label as it is drawn from under it, so that it will conform somewhat to
the shape of the can. Were this rod not used, the pasted end of the label by
being dampened on the inner surface would curl in à reverse direction and not.
come naturally to the curved face of the can.
The rod as described is practically rigid, but it may be spring held as shown in
Fig. 14.
M is a yielding upwardly-curved rubber-coated bed, situated between the com-
pression rolls G and J the object of which is to press the labels tightly around
and on to the cans at the termination of the pasting operation.
The delivery end of the frame A has a width which is less than the length of
the cans, and at its lateral edges there are rubber coated rails N' which are elevated
somewhat above the frame. The cans after they are labeled traverse these rails
and by being raised from the bed are not soiled by contact with a surface likely
to accumulate dust.
It is while passing along these rails that the portions of the label which extend
beyond the heads of the can are folded inward and towards the centre of the can
head, as shown in Figs. 12 and 13, which represent respectively a side and end
view of the labeled can.
To effect the folding of the ends of the labels, the exterior sides of the rails N¹
are provided with a series of curved and outwardly curled sheet metal blades 01
against each one of which in succession, an extended and cylindrical end of the
label is brought into contact. When the label comes in contact with the first
blade of the series, a portion of the paper cylinder formed by the overhanging
label is folded inward and as the can is rolled forward the second blade turns
inward another and adjoining portion of the label, and thus by the time the
labeled can has passed all the blades, the entire extended portion of the label at
:

page_text: each end of the can has been folded inward and flattened down on to the head.
The plates P are merely guides for the completely labeled cans until they are
discharged from the machine.
To prepare the machine for the operation of labeling cans, a stack or bunch of
labels is placed on the label holder, and the holding pawl released so that the
upper label of the stack is brought tightly up under and against the sharpened
pins.
The paste pot having been supplied with paste, and the tray with cement, the
lamp under the tray is lit and as soon as the cement is liquefied, the machine is
ready for the reception of cans.
The unlabeled cans are placed one against another on the inclined track at the
entrance end of the machine, and then the crank handle is turned at the proper
speed. The first can in coming in contact with the spacing rollers is rolled under
them and thrown forward so as to pass between the guide rails and under the
lower section of the feed belt by which it is carried forward. In passing the
revolving cement disks, the can receives two dabs of hot and liquefied cement,
and is thereby adapted to pick up a label from the bunch as it rolls over it.
In the picking up operation, the pointed pins which serve to keep the labels
in place cut through the label but the cuts are so short that the label is not
injured at all thereby.
The can now passes over the lower section of the pasting belt, and that device
is forced down so as to apply paste to near the free end of the label which is
drawn from under the rod holding it down, and the applied paste is thereby
spread to the extremity or end of the label. The said rod also serves to give the
free end of the label an inward curl which adapts it to fit against the can body
as before described.
At this stage of the operation the can is labeled but the unpasted ends of the
label which project as cylinders beyond the heads are unfolded.
As the can proceeds it comes in contact with the star wheel and that device is
turned one quarter of a revolution which has the effect of moving the pasting
belt a short distance so that a new portion of the belt is applied to the next can
which comes along.
The can now passes under the large pressure rolls which firmly press the pasted
end of the label against the can body, and thence to the folding blades whereby
the projecting ends of the label are crimped or folded so as to lie closely against
the heads of the can, as before described.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner same is to be performed, I declare that what I
claim is:-
1 In a labeling machine, a bed and devices to roll a can along the same,
mechanism to support a stack of labels in the bed of the machine and in the
path of the can, the said labels being of such width as to extend beyond the heads
of the cans, devices to apply the upper label of the stack to the body of the can
as the can is rolled over it, combined with fixed or stationary folders which in the
rolling of the can fold in and onto the heads of the can the extended ends of the
said label, substantially as specified.
2-In a labeling machine, a bed and devices to roll a can longitudinally of the
same, mechanism to support a stack of labels in the bed of the machine and in
the path of the cans, the said labels being of such width as to extend beyond the
heads of the can, devices to apply the upper label of the stack to the can as it is
rolled over it, combined with fixed or stationary outwardly curled blades which
constitute folders, against each one of which, in concession the overhanging
portion of the label is brought into contact, whereby the ends of the label are
turned in and flattened against the heads of the can, substantially as specified..
3 In a labeling machine, a bed and devices to roll a can longitudinally of the
same, mechanism to support a stack of labels in the bed of the machine, and in

page_text: the path of the cans, the said labels being of such width as to extend beyond the
heads of the can, devices to apply the upper label of the stack to the can as the
can is rolled over it, combined with a series of curved blades which constitute
folders, the degree of curl of the several blades diminishing in succession in the
direction taken by the cans, whereby the folding in and flattening of the over-
hanging ends of the label is gradually effected, substantially as specified.
