page_text: LETTERS PATENT to Charles. Anderson, of Fettykil, Leslie, in the County
of Fife, North Britain, Manufacturer, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR REGULATING OR ADJUSTING THE POSITION OF
ENDLESS TRAVELLING WEBS OR BANDS EMPLOYED IN VARIOUS KINDS OF
MACHINERY."
Sealed the 21st April 1868, and dated the 8th November 1867..
PROVISIONAL SPECIFICATION left by the said Charles Anderson at the
Office of the Commissioners of Patents, with his Petition, on the
8th November 1867.
I, CHARLES ANDERSON, of Fettykil, Leslie, in the County of Fife, North
Britain, Manufacturer, do hereby declare the nature of the said Invention
of "IMPROVEMENTS IN APPARATUS FOR REGULATING OR ADJUSTING THE POSITION
OF ENDLESS TRAVELLING WEBS OR BANDS EMPLOYED IN VARIOUS KINDS OF MACHINERY,"
to be as follows, that is to say :-
This Invention relates to an improved system or combination of mechanism
for the purpose of regulating or controlling endless travelling webs or bands
employed in various kinds of machinery when such happen to depart from

page_text: their usual course. For this purpose a guiding roller which is supported at
each end on a framing having suitable bearings is used, the web or band
rests on and passes over this roller, and when at work gives it a revolving
motion; immediately underneath and stretching across the web or band, but
clear of it, is a rod which is supported at each end on small levers fitted to a
stud on the framing or other suitable place, near the end of this rod is fixed
a metal blade close to but clear of both edges of the web or band. The
bearings of the conducting rollers consists of a box-shaped bracket with a
brass bush fitted and working into it so that it may slide either way by the
action of a screw shaft fitted into the box bracket and passing through the
under part of the brass bush. The screw, shaft has bearings at each end of
the box bracket and has small bevilled pinions keyed on each end on one side
of the bracket, and towards each end are fixed round studs on which is fitted
to run loosely bevelled pinions gearing into the wheels. The pinions on the
side are cast with long square necks, and are kept in their places by cotters
fixed on the end of the studs. On these square necks ratchet wheels are
fitted with square eyes, and the ratchet wheels are connected by a suitable
clutch to a double lever having a centre bearing on a stud which is fixed
vertically on a suitable projection cast or fitted on the centre of the box
bracket. To one end of the double lever the wooden rod is fixed, and on the
spindle of the conducting roller is fixed a bevilled plate. When the web or
band is in its true position the ratchet wheels are set so that they clear
without touching the bevilled plate. It will be seen that if the web or band
travels laterally, it must carry the rod on which the plates are fixed with it,
and the rod being attached to the double lever, which is connected with the
ratchet wheels, they too must move so that one of them will be thrown into
the circuit of the bevelled plate as it revolves, thereby giving motion to one of
the ratchet wheels, and these having a square eye fitted on the neck of the
bevelled pinion must give motion to the other pinion fixed to the screw shaft,
and it being turned either one way or the other according as the web or band
may travel laterally either to one side or the other, screws the brass bush
along the surface of the box bracket and thereby throws the guiding roller out
of the square to the right or left as may be required, and this change prevents
further displacement of the web or band.

Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of November, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles Anderson, Her special license that I, the said Charles Anderson,.
my executors, administrators, and assigns, or such others as I, the said Charles:
Anderson, my executors, administrators, or assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR
REGULATING OR ADJUSTING THE POSITION OF ENDLESS TRAVELLING WEES OR BANDS
EMPLOYED IN VARIOUS KINDS OF MACHINERY," upon the condition (amongst
others) that I, the said Charles Anderson, by an instrument in writing
under my hand and seal, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Charles Anderson, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment, reference being had to the accompanying Drawings, and to the letters
and figures marked thereon, that is to say :-
My said Invention relates to an improved system or combination of mechanism
for the purpose of regulating or controlling endless travelling webs. or bands
employed in various kinds of machinery when such happen to depart from their
usual course. For this purpose a guiding roller which is supported at each
end on a framing having suitable bearings is used; the web or band rests. on
and passes over this roller, and when at work gives it a revolving motion.
Immediately underneath and stretching across the web or band, but clear of
it, is a rod which is supported at each end on small levers fitted to a stud on

page_text: the framing or other suitable place; near the end of this rod is fixed a metal
blade close to but clear of both edges of the web or band. The bearings of
the conducting rollers consists of a box-shaped bracket with a brass bush fitted
and working into it so that it may slide either way by the action of a screw
shaft fitted into the box bracket and passing through the under side of the
brass bush. The screw shaft has bearings at each end of the box bracket,
and has small bevil pinions keyed on each end on one side of the bracket and
towards each end are fixed round studs on which is fitted to run loosely bevil
pinions gearing into the wheels. The. pinions on, the side are cast with long
square necks, and are kept in their places by cotters fixed on the end of the
studs. On these square necks ratchet wheels are fitted with square eyes, and
the ratchet wheels are connected by a suitable clutch to. a double lever having
a centre bearing on a stud which is fixed vertically on a suitable projection.

It will be seen that if the web or band. travels laterally it must carry the rod
on which the plates are fixed. with it, and the rod being attached to the double
lever which is connected with the ratchet wheels they. too must move, so
that one of them will be thrown:: into the circuit of the bevilled plate as it
revolves, thereby giving motion to one of the ratchet, wheels, and these having
a square eye fitted on the neck of the bevilled pinion must give motion-to

as may be required, and this change prevents further displacement of the web
or band.
fixed. a bevilled plate.
And in order that my said Invention may be properly understood: I now
proceed more particularly to set forth the system, mode, or manner in or under
which the same is, or may be used or practically carried into effect, reference
being had for the sake of more complete elucidation to the letters and figures
upon the explanatory Sheet of Drawings which I have hereunto appended,
that is to say-
"
:
Figure 1 is a side: elevation; Figure 2 an end elevation; and Figure 3 a
plan of a self-acting. guide for regulating or controlling endless travelling webs
or bands used in the working of various kinds of machinery.constructed according
to my Invention.

page_text: It consists of a box bracket A which may be bolted to any part of the
framing of the machinery on which the guide is to be applied; B is a guide
roller, over which the travelling band or web C passes. One of the journals D
of the guide roller B is carried in a brass bush E; in which it must be fitted
to work easy so that it may not jamb when the roller is displaced or angled.
Through the under part of the bush E a screwed shaft F passes, and is carried
in bearings on each end of the bracket A. Bevil wheels G, G, are fitted on
each end of the screwed shaft F working in pinions H, H, carried on studs
fixed in the sides of the bracket A, the pinions being kept in position on the
studs by means of the collars a, a. A deep square boss is cast on the
pinions H, on each of which slides one of the ratchets I; I', which is connected
to the lever J by the link bracket K. The guide plates L, L, are carried
upon a wood or metal bar M stretching across the machine on which the band
or web is worked and supported at each end on levers N carried on studs
On
shown dotted on Figure 3. The lever J is also connected to the bar M.
the spindle of the guide roller B a collar O is fixed having attached a metal
plate P cut to an angle on one edge on which teeth are cut for actuating the
ratchets I, 1. The journal of the guide roller B, which is at the side of the
machine opposite to the guide, is supported in a suitable bearing attached to
the framing.
The action of the machine is as follows:-When the web or band is
travelling in the direction indicated by the arrows on Figures 1 and 3 if the
web or band is running straight between the guide plates L the ratchets
will be in the position shown on Figure 3; but if the web or band should run
to one side from its true middle position and press against the guide plate Lit
will move towards the right, and the lever J will push the ratchet I to the right
and the ratchet I¹ towards the left until the ratchet I comes in contact with the
revolving toothed plate P, causing the ratchet I to revolve and turn the bevil
pinions in the direction indicated by the arrows. The screwed shaft working
in the bush E at the same time carrying the bearing of the guide roller in the
direction indicated until the angle or displacement of the guide rollers thereby
caused is sufficient to stay the lateral movement of the web or band C, and
the pressure is removed from the guide plate L. If the web or band should
run to the left side of the roller and press against the guide plate L¹ a similar
action in a contrary direction is produced in the manner herein-before described.
By this means whatever side the web or band has a tendency to run to the
self-acting guide acts upon the guide roller so as to displace or angle the roller
in the direction necessary to cause the web or band to move towards its normal
ition

page_text: Having now described the nature of my said Invention, and the manner in
or under which the same is or may be used or practically carried into effect,
I would observe in conclusion that what I consider novel and original, and
herefore claim as the Invention secured to me by the herein-before in part
ecited Letters Patent is, the general arrangement and construction of
nechanism as herein-before described for guiding travelling wires, felts,
ands, or webs used in various kinds of machinery, or any mere modification
hereof.
In witness whereof, I, the said Charles Anderson, have hereunto set my
hand and seal, this Fourth day of May, One thousand eight hundred
and sixty-eight.
CHARLES ANDERSON. (L.S.)
