AN IMPROVEMENT IN BELT SHIPPERS
Year: 1860

page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "AN IMPROVEMENT IN BELT SHIPPERS."-A communication
from abroad by John C. Goar, of Monterey, in the State of California and
United States of America.
Sealed the 18th January 1861, and dated the 5th September 1860.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
5th September 1860.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature
of the said Invention for "AN IMPROVEMENT IN BELT SHIPPERS," to be as
follows:-
This Invention of an improvement in belt shippers consists in furnishing
the slide, by the movement of which the belt is moved from one pulley to
another, with two self-acting spring stops, one of which engages with a
stationary notch or its equivalent, in order to lock the slide in a position to
hold the belt on one pulley, and the other with a similar notch or its equivalent
for the purpose of locking the slide in a position to hold the belt on the other
pulley. These stops are attached to two cords or chains, so applied that by
pulling one of the cords or chains the slide is first unlocked, and then moved

page_text: laterally, in order to ship the belt on to one pulley, and by pulling the other
one the slide is first unlocked, and then moved in the opposite direction to
ship the belt on to the other pulley, and the slide is afterwards locked.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office
on the 5th March 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of September, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Edward Newton, Her special license that I, the said William Edward
Newton, my executors, administrators, and assigns, or such others as I, the
said William Edward Newton, my executors, administrators, and 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 "AN IMPROVEMENT IN BELT SHIPPERS," being a communication from abroad,
upon the condition (amongst others) that I, the said William Edward Newton,
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 William Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention of an improvement in belt shippers consists in furnishing
the slide by the movement of which the belt is moved from one pulley to
another with two self-acting spring stops, one of which engages with a
stationary notch, or its equivalent, in order to lock the slide in a position to

page_text: hold the belt on one pulley, and the other with a similar notch, or its equivalent,
for the purpose of locking the slide in a position to hold the belt on the other
pulley. These stops are attached to two cords or chains; so applied that by
pulling one of the cords or chains the slide is first unlocked, and then moved
laterally, in order to ship the belt on to one pulley, and by pulling the other
one the slide is first unlocked, and then moved in the opposite direction to
ship the belt on to the other pulley, and the slide is afterwards locked.
In the accompanying Drawing Figure 1 is a front view of a belt shipper
constructed on the improved plan; Figure 2 is a transverse vertical section of
the same; Figure 3 is a horizontal section of the same.
In the Drawing A represents a cast-iron plate, or any fixed piece of metal
or wood, to which are attached the fixed horizontal guides a, a, and a¹, a',
within or between which works the shipper slide B. A slot b is made in the
slide B to receive the belt D. E, E', are the two stops, consisting of elbow-
shaped levers working on fulcrum pins c, c¹, secured in the slide B, and each
having a square tooth d, d, to enter one of two square notches e, e', in the
lower guides a¹, a¹. These notches and stops are so arranged that when the
slide is in position to keep the belt upon the pulley F, the tooth of the stop E
enters the notch e, and when the slide B is in position to keep the belt upon
the pulley F, the tooth of the stop E¹ enters the notch e, in either case
locking the slide and securing the belt upon the pulley F or F¹, as the case
may be. G is a double spring secured to the slide B, and operating upon
both stops to force their teeth downward, so that they will drop automatically
into their respective notches as they are caused to arrive over them by the
movement of the slide, and thus lock the slide. 9, g', are slot pins fixed in
the slide B, to arrest the spring stops E, E¹, when the latter have been drawn
out of the notches e, e¹. H, H¹, are two cords or chains, attached one to each
of the stops E, E¹, and each passing over one of two pulleys I, I, working in
frames J, J, attached to the plate or stationary piece A, and hanging down
therefrom to a suitable position to be laid hold of by the person whose duty it
is to ship the belt.
In the Drawing the shipper slide is represented locked by the stop E' in a
position to keep the belt D upon the right-hand pulley F¹. When it is desired
to ship the belt on to the left-hand pulley F the attendant pulls the cord or
chain H', and by that means first draws the spring stop E' out of the notch e¹,
and into contact with the stationary stop g³, and then draws the slide to the
left, and draws the belt over to the pulley F, and when the belt arrives there
the tooth of the stop E arrives at the notch e, and by dropping thereinto locks
the slide. In like manner, when the slide is in the latter position and the

page_text: cord or chain H is pulled, it first draws the tooth of the stop E out of the
notch e, and then draws the slide B to the right, and ships the belt on
to the pulley F¹, and the stop E¹ drops into the notch e¹, and locks the
slide.
Having now described this Invention of an improvemest in belt shippers,
and having explained the manner of carrying the same into effect as com-
municated to me by my foreign correspondent, I claim as the Invention secured
to me by Letters Patent as aforesaid, the mode herein set forth of constructing
and working belt shippers.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, this Fifth day of March, in the year of our
Lord One thousand eight hundred and sixty-one.
