Improvements in or connected with Machinery or Apparatus for
Wrapping Soap or other Material in Paper Covers.
I, JOSEPH WATSON, of Whitehall Road, Leeds, in the County of York, Soap
Manufacturer, do hereby declare the nature of this invention to be as follows:
The object of my invention, is to construct apparatus whereby cakes of soap or
other material, may be wrapped in paper covers in a speedy and efficient manner,
thereby obviating the waste of time and labour hitherto necessary in wrapping
Soap by hand.
At the
According to my invention, I provide a drum which may be of octagonal shape
having four or other suitable number of moulds or recesses in same, for the recep-
tion of the soap and the wrappers, and the bases of the said moulds are capable of
rising and falling, being connected together in pairs by rods passing through the
drum. The drum which is mounted in the frame of the machine, is provided with
grippers which open and close at the required time through the medium of suitable
cams or cam surfaces, and the said drum is rotated step by step by a suitable step
motion. A paper holder is attached to the frame near the drum, and a feeder is
provided over the holder, motion being imparted to the said feeder from the pawl
motion which actuates the drum, in such a manner that separate sheets of paper
are fed to the grippers, thus enabling the latter to take hold of the sheet of paper
and hold it in position over the mould until the cake of soap is inserted.
opposite end of the machine to that occupied by the drum, a cam shaft is provided,
the said shaft carrying a number of cams hereafter referred to, and on the end of
the cam shaft a spur wheel is mounted, the said spur wheel gearing with a pinion
carried on the driving shaft of the machine. Opposite the drum, a horizontal
sliding plate is provided, having springs on its upper side; and the said horizontal
sliding plate is actuated at the required time by a cam situated on the cam shaft, in
such a manner that it folds the first lap of the paper round the soap, whilst the
springs hold the second lap against the surface of the drum. A spring plate or
straight edge, working in radial or vertical guides, is operated from a cam or
cams on the cam shaft immediately after the horizontal sliding plate has made
its movement, and the said spring is so arranged that it passes in close contact
to the face of the drum on its being actuated. This action folds the second lap
round the soap, and an air piston which may be actuated from the cam shaft,
projects a draught of air at the required time on the surface of the drum, so as to
prevent the second lap sticking to the surface of the said drum. Two pairs of
fingers situated on opposite sides of the machine, have a forward movement
imparted to them from cams on the cam shaft, and the said fingers are opened
apart by auxiliary cams, which latter may be actuated from the cam shaft. These
fingers have the effect of making the first end folds after the two side laps have
been folded in, and the fingers are so arranged that the upper finger in each pair
withdraws before the lower one, leaving the latter to hold the fold in its place until
the next fold is partially formed.

page_text: Two sets of folding blades are provided, one set having a downward movement,
and the other set having an upward movement, the first of these movements making
the second end fold, and the second movement making the third end fold; and the
movements of these folding blades are transmitted from cams on the cam shaft.
A channel slide is provided beneath the drum, and a reciprocating discharger is
provided for discharging the wrapped cakes of soap along the channel; and on the
upper portion of the sides of the channel two folding plates are provided for
the purpose of completing the last end folds. Jets may be fitted in the sides of the
channel for the purpose of ejecting small quantities of paste or other adherent
beneath the last folds prior to their being folded down, thus firmly securing the
wrapper in position.
Instead of supplying separate sheets of paper for wrapping the soap, a continuous
roll may be employed, in which case a cutting off appliance would be provided
for dividing the paper into sheets; and a printing apparatus might be provided for
printing the paper supplied.

Improvements in or connected with Machinery or Apparatus for
Wrapping Soap or other Material in Paper Covers.
I, JOSEPH WATSON, of Whitehall Road, Leeds, in the County of York, Soap
Manufacturer, 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:-
The object of my invention, is to construct apparatus whereby cakes of
soap or
other material, may be wrapped in paper covers in a speedy and efficient manner,
thereby obviating the waste of time and labour hitherto necessary in wrapping
soap by hand.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer
to like parts in all the figures.
Figure 1 is a sectional side elevation of a machine constructed according to
my invention. Figure 2 a part side elevation, Figure 3 a part cross section,
Figure 4 a sectional plan, and Figure 5 a part plan, all of the same machine.
Figures 6, 7, 8, 9 and 10 are detail views. Figures 11 to 18 are diagram views.
A is the frame of the machine, and B is a drum carried on a shaft C and which
is provided with recesses D) in same for the reception of the soap and the wrappers:
The recesses D are provided with movable bases E the opposite pairs of which are
connected together by means of pairs of rods F and G, which pass through suitable
apertures in the drum B and the shaft C. Hare grippers, which are provided on the
drum B for the purpose of holding the wrappers at the required time, and the tails H
of the said grippers are situated in such a position that they come into contact with
a projection J which is capable of receiving a rocking movement on the shaft C.
K is a cam shaft which carries a number of cams for operating the various parts of
the machine, and L is a clutch, which through the medium of spur wheels L'
and L10 connects or disconnects at will the driving pulley L2 to or from the cam
shaft K. The clutch L is actuated from a treadle L³, through a fork L, shaft L³,
arm L6, and connecting rod L', a weighted rod Ls being provided for tending to keep
the clutch L in action and a weighted catch L being employed for retaining the

page_text: treadle L³ down when it is once depressed. B¹ is a spur wheel gearing with the
spur wheel L', and B is a stud carried on plates attached to a wheel B4, in such
a manner that the said stud engages with a slotted plate B3 with each rotation of
the spur wheel B¹. The spur wheel B¹ being the same size as the spur wheel L10
and their being driven off the same spur wheel L', 'cause them to rotate at the
same speed, with the result that with every revolution of the shaft K the slotted
plate B3 is moved one slot forward, and the shaft C on which it is keyed and which
carries the drum B, is moved one quarter of a revolution. The projection J is
carried on a boss J, and J2 is an arm attached to the boss J₁ and which is connected
through connecting rods J3 and J4 with an adjustable stud J5 on a link J. The
joint of the connecting rods J3 and J4, is carried on the end of a link J7, and move-
ment is imparted to the link J through a stud on same working in a cam slot in a
cam J8 which is carried on the shaft K. M is an endless travelling band which
feeds the cakes of soap to a feeder M¹ and the latter is coupled by means of a
connecting rod M2 with an adjustable slotted lever M³, an opposite arm M of
which carries a stud working in a cam M. N is a channel along which the
feeder M feeds the soap, and N1 is a plunger for feeding the soap at the required
time to the recesses D in the drum B, movement being imparted to the plunger N¹
through the medium of a cross head N2, connecting rods N³, arms N₁, shaft No,
arm Ne, carrying a stud on its outer end, and a cam N7 which is carried on the
cam shaft K before referred to. P is a spring plate which tends to keep in contact
with the face of the drum B, and R is a straight edge working in vertical guides R¹.
The straight edge R receives a quick downward motion and return through a pair
of slotted arms Rs, shaft Rs, arm R', connecting rod R5, link R6 and a cam R7 which
imparts motion to the link R6 through a stud carried by the latter. SS are two
pairs of fingers situated at the back and on opposite sides of the drum B, and the
ends of the fingers S are connected to a lever Si which carries a stud working in a
cam S2 carried on the cam shaft K. The upper finger S is fulcrummed on a pin $7
and a slot S8 on the end of the lower finger S fulcrums the latter to a pin Son
the lever S¹ at the same time allowing the lever S¹ to move a short distance at the
commencement of each of its movements without at first moving the lower finger S.
This loose slotted fulcrum of the lower finger S causes the latter to be moved away
from its work a little later than the upper finger S. S³ is a shaft which is rocked
by the movements of the link J7, and auxiliary cams S are carried on the shaft $3
the said cams being formed with controlling pins $5 and central portions S6, which
close and open the fingers S according to the movements of the link J. RB are
folding blades situated on opposite sides of the straight edge R, and the continued
movement imparted through the cam R' causes the blades R8 to come into contact
with the wrapper at the ends of the cake and to form the second end folds before
the lower fingers S have been entirely withdrawn, thus allowing the latter to hold
the first end folds in place until the second folds are partially formed. T are
lower blades; which are carried on arms T¹, and T2 is a rod for connecting the
arms together and T³ are rollers which run on cams T4, which latter being mounted
on a shaft T receive motion from a tooth wheel T through the medium of a
chain T7 actuated from a tooth wheel Te carried on the end of the shaft K. V is a
shaft which receives motion from a tooth wheel V₁ through the chain T7, and V2 is
a crank which is coupled by means of a connecting rod Vs to a feeder V4 working
in a channel V5. Ve are blades for effecting the last end folds on the wrapper.
The soap to be wrapped is fed to the machine by the travelling band M which
feeds the soap, cake by cake, in front of the feeder M', which latter through the
medium of the cam M5 feeds the soap forward along the channel N. The wrapper X
is fed from the table to the grippers H whilst the drum. B is in a stationary position.
and the projection J which for а short period holds the gripper
tail H. is now released by the movement of the projection J, thus
causing the gripper to hold the front edge of the wrapper X. The
drum B now rotates a quarter of a revolution, to the position
shewn in the detail view at Figure 11, and the plunger N¹ descends pressing the

page_text: cake of soap onto the wrapper X and into the recess D, at the same time depres-
sing the base E, as seen at Figure 12. In this figure the wrapper X is seen to
have been pulled equally on both sides by the soap, the side held by the gripper
being drawn out free, leaving both sides of the wrapper loose and free. The
drum B is then rotated for a further quarter of a revolution, and during this move-
ment of the drum B, the spring plate P comes in contact with the front edge of the
wrapper X and makes the first fold, as seen at Figure 13. The straight edge R
now descends and forms the second fold over the first fold, as seen at Figure 14,
and whilst the straight edge R is in this position, the fingers $ advance, as seen
at Figure 15, and after slightly opening apart so as to effectually form the first
end folds, they retire with the upper finger S slightly in advance of the lower
finger S. Just before the complete retirement of the said fingers S, see Figure 16,
the continued movement of the cross head R2 brings the blades R8 into contact
with the ends of the wrapper X, thus forming the second end folds; and as the
said blades R8 retire upwards, the blades T are raised, thus forming a third end
fold overlapping the second fold before described, as seen at Figure 17. On the
drum receiving another quarter of a revolution, the wrapped cake of soap is carried
round to the position at the base of the drum, the surfaces of the blades T keeping
the end folds of the wrapper X firmly in position, and on the lowering of the base
plate E owing to the insertion of a cake in the recess on the upper side of the
drum, the wrapped cake is ejected into the trough V5 along which it is fed by the
feeder V. The wrapped cakes are fed along the trough V5 with the end folds of the
wrapper X pointing upwards, and as they come to the blades V6, these end folds are
turned down, as seen at Figure 18, onto the wrapped cake and the same is ready
for removal.
Jets may be fitted in the sides of the channel, for the purpose of ejecting small
quantities of paste or other adherent beneath the last folds prior to their being
folded down, thus firmly securing the wrappers in position.
Instead of supplying separate sheets of paper for wrapping the soap, a continious.
roll may be employed, in which case a cutting off appliance would be provided for
dividing the paper into sheets; and a printing apparatus might be provided for
printing the paper supplied.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. The drum B having recesses D in same for the reception of the soap and the
wrappers, in combination with suitable plates and folding blades for folding the
wrappers round the soap, substantially as and for the purposes set forth.
