[Communicated from abroad by WILLIAM WALTER, of No. 337 West 24th Street,
in the City of New York, in the County and State of New York, United
States of America, Manufacturer.]
Improvements in Machines for Coating Cream Drops or other
Confections with Chocolate or other Coating Solution.
I, 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 to be as follows:-
The invention relates to improvements in machines for coating pieces or drops
of cream, caramel, candy or other filling material with chocolate or other coating
substance by dipping the same into the liquid chocolate or other substance and
after elevating the same therefrom subjecting the tray carrying the then coated
pieces to a concussion action by which the surplus chocolate is removed from
the pieces and the latter are left in a finished condition.
The machine embodying my invention consists in a hot water or steam jacketed
oblong receptacle adapted to contain the chocolate or other coating substance in
solution, a vertically reciprocating tray located normally over said receptacle and
formed with a series of pockets or cups, each to hold one piece or drop to be
coated, a hinged open frame lid or cover for said tray and adapted to retain
the said pieces or drops in said pockets, means for lowering the said tray
carrying the pieces to be coated into the chocolate or other substance within
said receptacle and then elevating the same above said solution and to about the
upper edge of said receptacle and there temporarily arresting it, means for
jarring said tray while thus arrested to cause the removal of all superfluous
chocolate from said pieces then coated, and means for thereafter elevating said
tray to its highest position where the coated pieces are removed and additional
uncoated pieces are placed into the pockets thereof to be coated during the
succeeding descent of said tray.
In accordance with one part of my invention the said tray having the pockets
to receive and carry the pieces to be coated is made reversible for convenience
in quickly applying and removing said pieces and in causing them to be dipped
while their upper surfaces are pointing downward; and in accordance with a
further part of my invention, the pivots sustaining said reciprocating tray have
cams by which then said tray is elevated to its highest position and then
reversed to turn the open mouths of the pockets downward for the purpose of
discharging the coated drops upon a suitable receiving plate or board, the said
tray will reach a slightly higher elevation and be drawn into line with a
vibrating arm which will strike against the then reversed tray and jar the
coated drops or pieces sufficiently to cause their ready discharge upon the said
plate or board, which will be held by the attendant to receive them.
The machine embodying my invention is provided with two independent
clutches, one to communicate the power to the driving shaft and the other to
automatically stop the machine at the end of each ascent of the vertically
reciprocating tray and afford means for manually starting the machine again as
soon as the coated pieces have been removed from the pockets of the tray and

page_text: their places filled with uncoated pieces. The first mentioned clutch enables the
operator to stop the machine at any point, while the other clutch operates
automatically to stop the machine at the end of each ascent of the vertically
reciprocating frame.
By means of my machine cream drops in large quantities may be quickly
coated with chocolate, the said vertically reciprocating tray being capable of
dipping at one operation as many of the cream drops as there are pockets in
the tray. The tray may be of any suitable size adapted to enter the receptacle
containing the chocolate in solution and I have usually provided in said tray
about one hundred and eighty of the pockets, each adapted to carry a cream
drop. The said tray will preferably be made of wire, in the form of an open
frame or sieve, the wires of said frame being bent at regular points to form
depressions or pockets adapted to hold the cream drops.
The vertical movement of the said tray is effected by suitable cams and inter-
mediate connections and the cover for the said tray is closed automatically by the
mechanism connected with the machine.

Improvements in Machines for Coating Cream Drops or other
Confections with Chocolate or other Coating Solution.
I, 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:-
The invention relates to improvements in machines for coating pieces of cream,
caramel, candy or other filling material with chocolate or other substance by
dipping the same into the liquid chocolate or other substance and after elevating
the same therefrom subjecting the tray carrying the then coated pieces to a
concussive action by which the surplus chocolate is removed from the pieces
and the latter are left in a finished condition.
The machine embodying my invention comprises a hot water or steam-jacket
oblong receptacle adapted to contain the chocolate or other coating substance,
a tray located normally over said receptacle and formed with a series of pockets
each to hold one piece or drop to be coated, a hinged open-frame lid or cover
for said tray and adapted to retain the said pieces or drops in said pocket,
means for lowering said tray carrying the pieces to be coated into the chocolate
or other substance within said receptacle and then elevating the same to about
the upper edge of said receptacle and there temporarily arresting it, means for
jarring said tray while thus arrested to cause the removal of all superfluous
chocolate from said pieces then coated, and means for thereafter elevating said
tray to its higher position where the coated pieces are removed and additional
uncoated pieces are placed into the pockets thereof to be coated during the
succeeding descent of said tray. In accordance with a portion of my invention
the said tray having pockets to receive and carry the pieces to be coated is
made reversible for convenience in quickly applying and removing the said
pieces and in causing them to be dipped while their upper surfaces are pointing
downward; and in accordance with a further part of my invention the pivots
sustaining said movable tray have cams by which when said tray is elevated to

page_text: its higher position and then reversed to turn the open mouths of the pockets
downward, the said tray will reach a slightly greater elevation and be brought
into line with a vibrating arm which will strike against the then reversed tray
and jar the coated drops or pieces therefrom upon a suitable plate held by the:
attendant to receive them.
The machine embodying my invention is provided with two independent clutches,
one to communicate the power to the driving shaft and the other to automatically
stop the machine at the end of each ascent of the vertically movable tray and afford
means for manually starting the machine again as soon as the coated pieces have
been removed from the pockets of the tray and their places filled with uncoated
pieces. The first mentioned clutch enables the operator to stop the machine at any
point, while the other clutch operates automatically to stop the machine at the end
of each ascent of the vertically movable tray.
The invention embraces further novel features of construction and combination
of parts, all as hereinafter more fully described, and particularly pointed out in the
claims.

page_text: Figure 17 is a vertical section of same on the dotted line 17-17 of Figure 16,
and showing in one of the pockets a confection to be coated.
In the drawings A designates the main supporting table or frame of the machine,
and upon this table is securely bolted the receptacle B adapted to contain the
chocolate or other substance and provided with the water jacket C, the latter being
of usual construction and adapted to receive hot water for heating the contents of
the receptacle B.
The main driving shaft is designated by the letter D, and the auxiliary driving
shaft by the letter E, the latter having at its ends the corresponding cam
wheels, F, G, and intermediate said ends the gear wheel H and cam I. Upon the
driving shaft D is mounted the belt wheel J, the latter being adapted to turn freely
on said shaft or to be locked thereto by means of the sliding clutch K, which is
adapted to be moved toward or from the said belt wheel J by means of the hand
lever L. When the clutch K, by means of said lever L, is moved to engage the
belt wheel J, the motion of the latter will be communicated to the shaft Ď, and
when the said clutch K is moved from contact with the wheel J, the latter will turn
freely on the shaft D without rotating the latter.
Upon the shaft D and at the end thereof opposite to the belt wheel J, is provided
the pinion wheel M and the ratchet wheel N and the clutch O, the said pinion
wheel being loose on the shaft D, while the clutch sleeve O is keyed thereon and is
adapted to be operated by the hand lever P for the purpose of causing the said
pinion to rotate with the shaft D or to be cut off therefrom.
In accordance with my present invention, the clutch sleeve with its lever P is
arranged to be removed from the pinion automatically at a definite point in the
operation of the machine, as will be hereinafter explained.
The ratchet wheel M is fast upon the shaft D and co-operates with the pivoted
red Q, which extends upward toward the upper part of the machine and is provided
with a spring R which creates in said rod a constant tension toward the machine.
The rotation of the ratchet N against the lower end of said rod Q causes said rod
under the tension of the spring R to have the vibrating movement which is
utilized at the proper time to facilitate the removal of the coated pieces or drops
from the pockets of their carrying tray as hereinafter more fully explained.
The pinion M is in engagement with the gear wheel H located upon the auxiliary
shaft E and through the pinion M and gear wheel H the motion of the driving
shaft D may be communicated to the shaft E and the cam I thereon. The hand
lever P extends from the clutch sleeve O toward the front portion of the machine
and is provided with a spring S and stud T, the former creating a tension in said
lever to preserve the end of the said stud T against the said cam I, which is
provided at a definite point in the path of the said stud T with an aperture V
adapted to receive under the action of the spring S the said stud T.
As soon as
the shaft E and cam I have rotated sufficiently to bring the aperture V into
alignment with the stud T, the spring S will cause said stud to enter said aperture,
and the effect of the movement of the lever P which permits said stud to enter the
said aperture V, causes the clutch sleeve O to recede from that portion of the
clutch which forms a rigid part of the pinion wheel M and thereby cut off the motion
of the driving shalt D from the pinion M and gear wheel H, thus stopping the
operating mechanism of the machine without interfering with the rotation of the
main driving shaft D. In order to again set in motion the auxiliary driving
shaft E and the mechanism connected therewith it is necessary to manually move
the outer end of the lever P sufficiently to relieve the stud T from the aperture V
and cause the clutch sleeve O to re-engage that portion of the clutch which forms
a rigid part of the pinion wheel M.
-
The cam wheels F, G, upon the opposite ends of the auxiliary driving shaft E
correspond with each other in outline and each is provided along a concentric
portion of its periphery with the series of ratchet teeth W and adjacent thereto
with the lateral flange X. At one side of said cam wheels F, G, is formed the
depression a having diverging opposite sides b, c, the former merging into the line

page_text: of the ratchet teeth W, while the other lettered c merges into the elevated cam d,
which when the operative parts of the machine come to a stop at the end of each
revolution of the shaft E is in its upward position.
At opposite ends of the receptacle B are provided the lugs e which serve as
guides for the vertically reciprocating bars f and support the standards g, the latter
extending upward a suitable distance and having mounted upon them the slides h,
which at their outer ends are secured to the upper ends of the bars and at their
inner ends support the hangers i which extend downward within the vertical planes
of the ends of the receptacle B and support the rectangular frame, the latter
corresponding in outline with the interior of the receptacle B and being securely
held by means of screws a¹ upon the said hangers i so as to have a vertical
reciprocation therewith. The frame is provided with the inwardly projecting
supporting pins & and, also, with a small snap spring m, which at the proper time
serves to lock the hinged open frame or cover n downward in a horizontal position,
as hereinafter explained.
"'
The hinged cover n is mounted in lugs o secured at the opposite ends of the rear
side of the frame j, and the pivoted or hinged rod of said cover n is provided with
a lug which is so located as to be engaged by the lug q secured upon the
receptacle B and extending over the edge of the latter in convenient position to be
met by the lug during the upward movement of the frame j and cause by its
restraint on the lug p the cover n to turn upward to its open position. During the
downward movement of the frame j, the lug 9 will come into contact with the
cover n above its lower hinged edge and tilt the said cover forward in order that it
may close downward over the frame j and be there secured by means of the spring
clip m. The vertical slide rods f, the slides upon the standards g, the hangers i
suspended from said slides and the frame j constitute, as it were, an integral
frame which has a vertical reciprocating motion; its upward position being
The lower end of
illustrated in Figure 2 and its lower position in Figure 11.
the vertical rods f pass through guides e, as above described, and also, between
the studs r, r, which, also, operate as guides for the lower end of said rods f.
The frame is an independent supporting frame and receives its vertical
reciprocation from the cams F, G, located at the opposite ends of the auxiliary
driving shaft E, and said frame is aided in its downward movement by means of
the coiled spring s, s, located upon the upper ends of the standards g above the
slides h. Upon the outer surfaces of the bars fare secured the boxes t, t, whose
lower inner surfaces are pawl-shaped and rest upon the cam wheels F, G, as
indicated in Figures 2 and 5, and whose outer portions inclose the vertical
adjusting screws w, we, and at their lower ends receive followers holding the
elastic or soft cushions or plugs a, a, which are beyond the vertical plane of the
outer cam surfaces of the wheels F, G, and are in position to come into contact
with the lateral flanges X, X, when during the rotation of the said wheels F, G,
the ratchet teeth W are passing below the boxes t, t. The purpose of the
screws w, w, is to adjust the extent of the cushions c, a, which shall be exposed
below the lower ends of the boxes t, t, and thus regulate the extent the vertical
movement the said boxes t and frame j with their intermediate connections shall
have while the teeth W are passing below the said boxes, as hereinafter
explained.
:
When the cams F, G, are in their normal position at rest, as indicated in
Figure 3, the higher part d of the said cam wheels will be uppermost and will

power is applied to the shaft E and the cam wheels F, G, thereby set in motion,
they will revolve in the direction of the arrow shown in Figure 3, and hence the
surface c of the cam wheels F, G, will pass beneath the boxes t and allow the same
to lower into the depression a cf said cam, this having the effect of lowering the
said boxes and frame j with their intermediate connections, to the position
illustrated in Figure 11; and during the continued movement of the cam wheels F, G,
the boxes t, t, will ride up the surfaces b.of the cams F, G, and the said boxes t and

page_text: the frame will be elevated to a position within the upper portion of the receptacle B
and below, the upper edge of said receptacle but above the level of the liquid
chocolate or other coating surface. At this time the teeth W of the said cam
wheels F, G, will, during the rotation of the said wheels, pass below the boxes
and cause said boxes to have a short vertical vibrating motion, whereby the said
frame will be jarred and all superfluous chocolate shaken from the coated pieces
and their supporting tray to be hereinafter referred to. The continued rotation of
the cam wheels F, G, after the teeth W have passed beyond the boxes t, will
bring the higher cam surfaces d below said boxes again and elevate the same and
the frame to their normal position illustrated in Figure 2, at which time, as
berein before described, the stud T will snap into the aperture V, provided in the
cam I, and thereby withdraw the clutch O from the pinion M and stop the machine.
The vertical vibration of the frame j imparts to said frame a concussive action
which may be intensified by the strength of the springs s, s. In the absence of the
adjusting screws w, cushions and flange X, each vertical movement during the
vibration of the frame ; would equal in extent the depth of the teeth W, but by
means of the said adjusting screws w, cushions and lateral flanges X, the extent
of the vertical movement of the frame j during its vibration may be regulated at
will, since it is obvious that when the screws w are adjusted downward, they will
cause the lowering of the cushions & toward the flanges X, and that if said
cushions are sufficiently adjusted they may prevent the lower pawl shaped ends
of the boxes & from reaching the depth of the teeth W by coming into contact with
the flanges X prior to the said boxes reaching the lower ends of the notches
between the teeth W. The vibration of the frame; and consequently the extent
of its jarring action may thus be regulated and adjusted by means of the screws w,
and at the same time it is to be observed that the cushions will prevent any undue
noise resulting from the action of the teeth W traveling below the boxes t.

After the cam wheels F, G, have attained their position illustrated in Figure 3
and the operative parts of the machine have come to rest, the said cam wheels will
not again start to rotate until the attendant by means of the handle
will move
the lever sufficiently to withdraw the said stud T from the aperture V and throw
the clutch into contact with the pinion M, upon which being done the notion
of the driving shaft D will, as herein before described, be communicated to the
auxiliary driving shaft. E and again set in motion the cam wheels F, G, and the
other operative mechanism of the machine.
Upon the opposite ends of the independent supporting frame is provided the
vertical guides A', which receive the pivots B' secured at the ends of the vertically
movable tray C¹ provided with the series of pockets D' adapted to receive the
pieces or drops to be coated, and which tray Ci is suspended at the lower ends of
the chains E which pass over pulleys F mounted upon the slides, the lower ends
of the said chains E' being secured upon the said pivots B' and the other or outer
ends thereof being secured to adjustable slides G³ located upon the upper ends of
the vibrating arms H', the lower ends of which are upon the rock shaft I', which
is mounted in the lugs upon the rear surface of the table A. The rock shaft l' is
provided with an inwardly extending arm J carrying a roller K³ in contact with
the periphery of the cam 1, as illustrated in Figure 3. During the rotation of the
auxiliary driving shaft E, the cam I will effect a vibratory motion in the arms H¹
causing their upper ends to approach the machine for the purpose of lowering the
tray and then recede from said machine at the proper time to elevate the said
tray C. The tray C' being hung upon pivots is reversible, the pockets D¹ being
thus capable of having their mouths turned upward or downward as may be
desired. In the normal position of the tray C¹ the pockets D' will point downward,
as shown in Figure 10, and thereafter upon the reversal of the tray Cupon its
pivots, the said pockets D₁ will point upward, as indicated in Figures 3 and 9.
The purpose of thus reversing the tray C₁ will be explained hereinafter.
The upper end of the guides A¹ for the pivots B is provided with a cam
surface L, and the pivots of the said tray C carry the cans M', which when the

page_text: said tray C is reversed or turned with the bottom of the pockets D' pointing
upward, will impinge upon the said cam surfaces L', and thereby cause the sail
tray C to have a slightly higher elevation than when said tray C is in its normal

position with the bottoms of the pockets D' pointing downward.
tray C is turned so that its pockets D¹ are pointed downward, the cams M' will
ride upon the said cam surfaces L' and the pivots B' will then be at the upper side
of the tray C and the latter will be held a short distance below the level it assumes
when reversed, as illustrated in Figure 10.
When the tray C is at its higher elevation shown in Figure 3, it will be in line
with the upper end of the vibrating arm Q, which during its vibration, will lightly
rap against the tray C¹aud tend to jar the coated drops or pieces from the pockets
thereof, as hereinafter referred to.
In order that the tray C' may be lightly locked in its horizontal position, I have
provided the spring pawl N to engage notches in the cam M' as indicated in
Figures 3 and 6, the said notches being inclined at both edges so as to permit the
attendant to readily turn the tray C without handling the pawl N.
The tray C is composed of the outer framing O and the series of oppositely,
laterally and correspondingly bent wires P, Q, and the intermediate downwardly
bent flattened wires R', which at the points S¹ between the oval outlines formed
by the curvatures or bendings of the wires P¹, Q', are soldered to said latter wires,
thereby forming a solid frame composed of the lines of pockets D'. The pockets D₁
are thus made oval at their mouths and their depth is regulated by the extent of
the curvature or bending of the flattened wires R', and in operation it is intended
that the pockets D' shall not contact with the pieces or drops to be coated, except
at three points, to being at the opposite sides of the pocket and the other at the
bottom of the pocket, thus leaving abundant means for the coating substance to
encompass the drops without danger of the latter becoming caught or fastened
into the pockets or having a symmetrical rounded appearance, but rather the
appearance of hand made goods.
The trap is provided with projecting lugs T¹ which are secured to the outer
framing and constitute stops for preventing the breakage or bruising of the
pieces or drops while being introduced to or removed from the pockets D.
When it is desired to introduce the pieces or drops to be coated to the tray C¹,
I, for convenience, first arrange them upon a board or frame V, illustrated in
Figure 12, which in the arrangement of its pockets corresponds with the tray C¹,
and then reverse the frame C₁ upon its pivots so that the pockets D' will point
upward, as indicated in Figure 3, care at this particular time being taken to give
the reversed tray C₁a slight inclination so that the vibrating rod Q, will not act
upon the said tray. The tray C₁ having been reversed in position and the pieces.
or drops to be coated having been placed upon the frame or board V', the latter
is placed directly below the said tray C¹, and moved upward toward the same in
order that the pieces or drops may enter the pockets D₁ and the board or frame V₁.
come into contact with the stops T', whereupon while the said board or frame VI
is in the position stated, the tray C₁ will be reversed upon its pivots so that its
pockets D will point downward and upon this being done, the frame or board V!
will be removed, leaving the pieces or drops in the said pockets D'. After the
board or frame V¹ has thus been removed from the frame C', the machine will be
set in motion by the movement of the handle y and lever P, as hereinbefore
explained, the result being that the cam I will turn to permit the lowering of the
roller K' and arm and thereby cause the rods H' to approach the receptacle B,.
whereby the chains E' under the weight of the tray C', will pass over the pulleys Fi
and permit the said tray C¹ to lower upon the supporting pins k in the frame j, as
indicated in Figure 11, upon arriving at which position, the rods H', further
approaching the receptacle B and the can wheels F, G, being in motion, the tray j
supporting the frame C¹ will be lowered into the receptacle B, the lug q in the
meantime starting the cover n to close over the tray C¹. The downward movement
of the tray carrying the frame C', results in the pieces or drops held. in the

page_text: pockets D being coated with the chocolate or other substance within the
receptacle B. The continued motion of the cam wheels F, G, first causes
the elevation of the frame j carrying the tray C₁ to a point within the upper edges
of the receptacle B above the liquid coating substance, when as above described,
the teeth W of the said cam wheels will pass below the boxes t and cause the
concussive vibration of said frame for the purpose of jarring from the frame and
the pieces or drops held in the pockets D' all superfluous chocolate, leaving the
drops or pieces in proper merchantable condition and form. As soon as the
teeth W of the cam wheels FG, have passed from the said boxes t, the cam
surfaces d of said wheels F, G, will pass below the said boxes t and elevate the
frame to its upward position illustrated in Figure 3, this having the effect of
causing the arm to elevate or open the cover n, which movement of the cover is
followed by the action of the cam on the rods H', which cam at this time will
through the roller K', arm J', rock shaft J', rods H¹, and chains E' draw the
tray Cupward to its normal position shown in Figure 10. Upon the tray C
reaching its upward position, the stud T on the lever P will snap into the
aperture V of the cam I and the clutch O will be withdrawn from the pinion M,
thus stopping the machine and permitting the removal of the coated pieces or
drops from the tray C¹.
The removal of the coated drops or pieces from the tray C¹ may be quickly
accomplished by applying over said tray a plate W', shown in Figure 14, which
will rest upon the lugs T, and then reversing the said tray C¹ upon its pivots so
that the pockets D' will be turned upward with their mouths downward, as shown
in Figure 15, at which time the plate N¹ will be in a position to receive all of the
drops or pieces which may fall from the tray C; the detachment of the said pieces
from the said tray C₁ being aided by the vibration of the rod Q against the said
tray. If any of the coated pieces should bind in the pockets D', the jarring of
the tray C by the rod Q will secure their detachment therefrom. The coated
pieces or drops having passed from the pockets D₁ upon the plate W₁, the latter
will be lowered from the tray C and thus all of the coated pieces or drops may be
removed at once.
The frame or board V' by which the pieces to be coated are introduced to the
tray C and the plate W₁ by which the coated pieces are removed from said tray C¹
are provided upon opposite edges with the lugs X' fitting the opposite edges of the
tray C and serving to prevent during the reversal of the tray C₁ the bruising or
injuring of the drops either coated or to be coated. The lugs X¹ preserve the due
relation of the frame V1 or plate W₁ with the edges of the tray C and the lugs T'
serve as stops to prevent the said frame V1 or the plate W' approaching too closely
to the tray C. The plate W' may be provided with a handle Y' for convenience
in carrying the same. As soon as the coated drops or pieces have been removed
from the tray C', the latter will be in condition to receive another supply of pieces
or drops to be coated and the operation of the machine above described may be at
once repeated as frequently as desired.
The invention is not limited to the use of any special coating substance in the
receptacle B, nor to the character of the pieces or drops to be coated, nor is the
invention limited to the details of construction, which may be varied within
the scope of the invention as claimed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
