Improvements in Confectionery Machines.
I, THOMAS ROBERTSON, of 107, Queen Street East, in the City of Toronto,
in the County of York, in the Province of Ontario, Canada, 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
My invention relates to improvements in confectionery machines patented
to me in Great Britain and Ireland under Number 23478 on the 20th day of
December 1892, and the object of the present invention is-first-to provide an
automatic means whereby the band of paper may be fed an increased space so as
to enable, it to be divided into sheets for convenience in handling and secondly-
to provide an automatic means for manipulating the cutter to sever the band
immediately upon the increased space coming beneath such cutter and it consists
essentially first-in providing a counter shaft suitably journalled in the frame of
the machine, driven from the gear wheel of the shaft through, which the feeding
rolls are rotated and providing a cam designed to co-act with a crank arm also
journalled on the feed driving shaft, one end of said arm having an adjustable
depending weight while the other end is provided with a pivoted dog designed to
engage with a tooth secured to the disc on the feed driving shaft and secondly-
in providing. at the opposite end of the feed driving shaft an arm having a pin
secured to it designed to co-act with the cam on the counter shaft, an adjustable
depending weight and roller being also provided on the arm, which roller is designed
to co-act at certain intervals with an arm secured on a shaft laterally adjustable by
means of a piroted lever operated from a serpentine cam on the counter shaft this
latter arm being connected by a pitman to another arm on the cutter spindle as
hereinafter more particularly explained.
The drawing represents a perspective view of portion of the machine with the
frame broken away and the feed rollers removed, so as to exhibit clearly only the
parts involved in or directly connected with my present invention.
In the Specification of my former Patent I have described the manner in which
the band of paper is fed by the feeding rolls and the manner in which the increased
space. is produced in the band by the manipulation of the operator. I do not
consider it necessary in this Specification to go again into the feed any more than
is necessary to explain the operation of, my improvements.
M, is the shaft at one end of which is secured the spur wheel, N, through which
the feed rollers for the band of paper. are driven by suitable gear pinions meshing
with each other. R, is the ratchet, wheel, S, an arm and, T, is a dog pivoted at
the upper end of the arm, S, and engaging with the ratchet wheel, R. U, is an
eccentric fixed to the driving shaft, J, and provided with an eccentric rod, V,
adjustably connected to the bar, S. ', is a disc secured on the opposite end of the
shaft, M, and, 1, is a crank arm provided with a pivoted dog, s'. u', is a pro-
jection secured on the periphery of the disc, t', and designed to be engaged by
the dog, s, pivoted on the short end of the crank arm, r. The projection, u¹,
extends laterally from the plate, which has a boss, u³, formed on it from which
the shaft, M, extends.. u, is a slot through which extends a bolt, u, into the
disc, t. By loosening the bolt the projection, u', may be adjusted on the disc for
the purpose of bringing the dog exactly behind the projection, and thereby over-
coming any lost motion. 1, is the cutter and, b', the band of paper. All of these
parts I refer to in the Specification of my former: Patent.

page_text: , is a rod pivotally attached to the end of the crank arm, r. The lower end
of the rod, is threaded and has screwed on to it a weight, ³, which may be
adjusted upon the rod, so as to allow of the weight having a greater or less drop
according to the space it is designed to move the band as will be seen in the
description hereinafter.
A, is the cam secured on the end of a counter shaft, B, which is journalled in
suitable bearings in the frame of the machine. The counter shaft, B, has secured
on the end inside the cam, A, a wing, C, as indicated by dotted lines, and the
cam, A, has an arc-shaped slot made in it through which passes the bolt, c. By
unloosening the bolt the cam may be adjusted upon the shaft, B, so as to bring the
end of the cam to proper point so that weight will drop at proper time. is a
pin extending outwardly from the arm, , and projecting sufficiently to come within
the sweep of the cam, A.
D, is a spur wheel secured on the opposite end of the shaft, B, and meshing with
the spur wheel, N, on the shaft, M. The spur wheel, N, is rotated in the direction
indicated by arrow by means of the eccentric, U, pitman, V, arm, S, dog, T, and
ratchet wheel, R, on the end of the shaft, M. The spur wheel, D, is consequently
.rotated in the opposite direction thereby causing the cam, A, to rotate in the
direction indicated by arrow. E, is a cam located on the opposite end of the
.shaft B, to that on which the cam, A, is situated and to the outside of a spur
wheel, D. G, is an arm loosely journalled on the shaft, M, outside of the spur
wheel, N. The arm, G, is provided with a pin, g, which extends outwardly from
it so as to be within the sweep of the cam, E. g', is a depending rod pivoted at, g₁,
on the arm, G, and provided with a weight, g³, which is vertically adjusted upon
the threaded lower end of the dog, g'. The drop of the weights, ³, and, 3, on
the depending rods, 1, and, y', regulates the movement of the arm, l, and, G,
respectively. g, is a friction roller secured on the end of the arm, G.
H, is a rock shaft suitably journalled in the frame of the machine and provided
with an arm, h, with an inclined end, '. The arm, h, is connected by the pitman, I,
to the arm, K, secured on the end of the spindle, ", of the cutter, f. L, is a
curved spindle having one end secured to the lug, k, of the arm, K, and the other
end extending through a bracket, l. 1, is a spiral spring extending between the
lug, k, and the bracket, 1. This spring is designed to throw the cutter up after
cutting the band of paper and the arm, h, into its normal position.
O, is a lever pivoted at, o, in the frame of the machine as indicated and provided
at its upper end with a friction roller, o', which extends into a grooved collar, P,
secured to the shaft, H. The lower end of the lever has a pin or roller, o", which
extends into a serpentine cam groove, q, in the collar, Q, which is attached to the
counter shaft, B. "The operation of this serpentine cam grooved lever and collar, o,
is to laterally adjust the shaft, H, at certain intervals, so as to bring the inclined
end,, of the arm, h, directly opposite to or away from the sweep of the roller, g".
on the end of the arm, G.
Having now described the principal parts involved in my invention I shall
briefly describe the operation. The ordinary space necessary for the delivery of
the drops on the band is fed successively by the dog, T, engaging with the ratchet
wheel, R, on the end of the shaft, M, and communicating motion by means of the
spur wheel, R, to the feed rollers described in my former Patent. The band is fed
"forward ordinarily as before described by the dog, T, engaging each successive
tooth of the ratchet wheel, S, so as to give the ordinary space between the drops.
The cam A, moving around in the direction indicated by arrow comes beneath the
pin, projecting from the arm; r. The cam when it has about reached its
greatest radius from the counter shaft, B, lifts, the pin, r, so as to throw the dog
back behind the projection, ul. When the end of the cam passes the pin, 7, the
weight,, causes the long arm of the crank arm,, to drop thereby causing the
'dog, s, to throw the projection and consequently the disc forward a space corre-
sponding to the drop of the weight...
1.
This quick motion is communicated through the feeding shaft, M, and through

page_text: the spur wheel, N, to the feed rollers, so that the band is thrown forward a double.
space or more, this of course depending on the drop of the weight, so as to provide
a sufficient space between the drops for the cutter to sever the band. The jumping-
feed of the disc, t', of course repeated as the band passes through the machine, so
as to form the increased spaces at equal distances apart through the band. The-
space between the tubes and the cutter corresponds as described in my former
Patent to the length of the sheet. Consequently the cutter, when the band is fed
forward the space beneath the tubes acts instantaneously to sever the band in the
space beneath it and this is accomplished automatically in the following manner.
At the time that the cam, A, has passed beneath the pin, 4, on the arm,, the
pin, g, has almost reached the end of the cain, E, on the opposite end of the-
shaft B, in fact so nearly so that upon the arm,, dropping the arm, G, drops.
immediately afterwards. At this period the lever, O, is thrown into the position
shown by dotted lines by the cam groove, y, so as to throw the shaft, h, laterally
and bring the inclined end, A', within the sweep of the roller, gl, on the end of the
arm, which roller as the arm drops forces the arm in the position shown in dotted.
lines thereby instantaneously causing the cutter to come down and sever the band.
The roller, o, on the end of the lever now passes into the straight portion of the
groove drawing the arm, h, outside the sweep of the arm, g. The cam, E, as it.
comes around again raises the arm, g, and the operation is repeated successively, so
that the cutter will sever the band instantaneously upon the band being moved the-
increased space.
By the means above described I am therefore enabled to produce a machine for
making drops, which is automatic throughout its action and requires no attention
on the part of the attendant except to remove the sheets of drops after they have.
been severed from the main body of the band.
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 .
