COMPLETE SPECIFICATION.
Improvements in and relating to Coin Freed Machines for the
Supply of Toilet Paper and the like.
I, FRANK ELLSWORTH HOUSH, a citizen of the United States of America,
residing at Brattleborough in the County of Windham and State of Vermont, one
of the United States of America, Publisher, to 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 :-
This invention relates to improvements in coin freed toilet paper machines, which
will be hereinafter more particularly described and pointed out.
In the accompanying drawings forming part of this Specification―
Figure 1 is an inside view of the machine showing the working parts.
Figure 2 is an inside view from one end.
Figure 3 is an inside view from the opposite end to Figure 2.
Figures 4, 5, and 7 are details of the several operative parts.
Figure 8 is an enlarged section of the paper roll core about the full size.
A, is the frame or shell to which all the operative machinery is attached on
the inside. This shell can be made of cast or sheet metal. Within the shell, A,
is secured, by screws or bolts, b, a standard, B, seen in Figures 1 and 4.
A slot, is formed to permit the axle c of a paper roll core, C, to be put in
or taken out easily for replacing the rolls of paper; the other end of the axle, c,
is supported in a bearing, C", on the inside of the shell, A. This axle, c, has
a crank, c, which is extended to pass loosely through a hole, d, in a ratchet
wheel, D, which wheel, D, has a shaft, d', having on its outer end a reversing
screw-thread, d", within a female screw box, E, Figures 6 and 7. This box, E,
has a set-screw, e, by which it can be secured on the shaft, e', where it is to
be placed relatively to the screw, d". The single thread, e", of E, is so bevelled
as to operate upon the threads of the reversing screw, d¹¹.
Below the shaft, d, as seen in Figure 5, is a crank shaft, F, having on one end
the crank, f, with a square wrist, f. On the shaft, F, is secured in a proper
manner, the arm or coin lever, F. These shafts, d', and F, are supported in the two
standards, B1, B, secured by screws to the shell, A. f is a counter-weight on
the shaft, F, by which the coin lever is brought back to its place after the coin has
tilted it down.
The ratchet wheel, D, is held against retrograde movement by a spring pawl, l,
and has near its periphery a counter-weight, D'. There is a hole, d, through the
wheel D, for the insertion of the crank handle, c' of the shaft c, of the core of the paper
roll, C. At any time required the shaft c and the roll can be removed and replaced
with but little trouble or delay by lifting the shaft c out of its place. The core is
seen in section about the full size in Figure 8; it is represented within a circular
case made of sheet metal or hardened paper-pulp or other material, which, is shown
in the figure to have an inner flange, g, inserted in a slot longitudinally cut in the
core, C. This circular case covers the entire length of the core, and has two or
three rows of holes, g', punched from the inside, so as to have slight projections or
burrs exteriorly, as shown, for the purpose of holding the roll of paper. It will
thus be seen that when the paper is rolled upon the metal lining at the factory, and
the core, C, run into it, the core and paper will be under the same influence-
that is, when the shaft, c is in place, and the paper is pulled, it must turn the shaft,
and as the shaft is turned, the crank being inserted in the hole, d, in the ratchet
wheel, D, the ratchet must also move correspondingly. Now, if there be any
obstruction intervening to prevent the ratchet wheel from turning, the paper roll
cannot be turned to deliver the paper.
It will also be observed, that when the ratchet wheel turns, the shaft, having

page_text: upon it the reversing screw-threads, d, working in the female thread, e¹¹, that
the wheel, when revolving on its shaft, gives the shaft itself a lateral movement
in both directions. Near the lower edge of the ratchet wheel, D, is seen a lug, .
These parts are
so arranged that when the wheel D, has revolved a certain
number of times the screw-thread e" has drawn the shaft d' so far in as to bring
the lug, , immediately in contact with the wrist, f¹, as seen in Figure 5, which
stops the wheel, D. This is regulated by means of the arm, F1, which is set on the
shaft, F, by the set screw, f", so that when the arm F¹, is in its normal position,
as in section, Figure 5, to close the coin channel H (in which position it is kept by
the counterweight ") the wrist is precisely in the way of the lug, h, on the
wheel, D, Figure 5. The counterweight, D¹, is at such a position that, should the
wheel, D, be released, its weight will carry the wheel over that point. Now if a
coin be dropped in the channel, H, it will fall upon the end of the arm, F1, force it
down, and consequently the crank arm, f, will be moved into the position to avoid
the lug, ', and it will immediately be thrown clear of the wrist, f, and pass freely
under it, the reversing screw will at once move the shaft, d', in the direction
away from the frame, B', and by the time the lug h has again reached the wrist,
it will clear it altogether and permit another revolution of the wheel.
It should be understood that after a person has dropped a coin into the slot he
should take hold of the end of the paper roll, which has emerged a few inches by
the power of the counterweight on the ratchet wheel, D, and give it a pull,
und, as before stated, the counterweight having prevented the wrist, f', from
engaging the lug, h', the operator can pull the roll, and deliver the paper, until
by the reverse motion of the shaft, d', it again causes the wheel, D, to approach
the frame, B, until the lug ¹ encounters the wrist, f' again, when it is arrested, until
another coin is dropped into the slot. The shutter, I, as seen in section in
Figure 2, is swung on a shaft, I', having at one end a crank arm or lever, i, shown
at its length in Figure 4. This lever, i, has attached to its outer end a counter-
weight,, to keep the shutter in a fixed position until the lever, i, is operated upon
by the lug h on the side of the ratchet wheel, D, as shown in Figure 2. As the
wheel revolves in the direction of the arrow always, this lug h impinges upon the
lever and carries it downward, until the lever is released. The continued
revolution of the wheel, D, carries the lug, h, beyond the end of the lever, i;
but, is so arranged that it does not touch the lever in the revolution of the
wheel, until by the lateral movement of the shaft the lug 4 is brought in contact
with the lever and carries it down to lift the shutter, I. The end of lever i is
released as soon as the wheel D begins to rotate, namely, when the coin drops on
the arm, F, and the counterweight, j, causes the end of lever i to pass upward
until the shutter is stopped by a guard k projecting from the bottom of the case,
as seen in Figure 2.
The main purpose of shutter, 1, is to clamp the end of the paper to hold it
while being torn off and to keep it in the right position to emerge through the
opening.
H is the channel for the coin, and its bottom is partially closed by the end
of the arm or lever, F'. J is the receptacle for the coin after it drops from the
arm, F
kis a knife by which the paper is cut off.
m is a roller suspended by wires, m', from the shell at n, and which rests upon
the sheet of paper and keeps it in place. .
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 shutter, I, made of any suitable form and suspended on a shaft, I', which
has at one end a lever, i, controlled by a counterweight, j, in combination with the
Ing, h, on the side of the ratchet wheel, D, substantially as and for the purpose
described.

page_text: 2. The ratchet wheel, D, with its lugs, h, and ', and counterweight, D', in
combination with the shutter, I, hinged to a shaft, 1', having a counterweighted
lever, i, whereby the loose end of the paper in a coin freed machine is controlled
and to insure its perfect delivery, substantially as and for the purpose described.
3. The combination of the reversing screw, d", and thread, e", within the box, E,
coin lever, F, having a counterweight f, shaft, F, crank arm, f, with its wrist, f',
ratchet wheel, D, having lugs, h, h', and counterweight, D', the shutter, I, shaft, I',
with its weighted lever, i, all substantially as and for the purpose described.
4. In a coin freed machine for delivery of paper in rolls, the core, having a
longitudinal slit, in combination with a removable tube having an inwardly pro-
jecting flange to correspond with the slit, and a series of burrs or projections ou the
exterior, substantially as and for the purpose described.
