Sealed the 11th November 1862, and dated the 17th May 1862.
PROVISIONAL SPECIFICATION left by the said John Christopher Gore at
the Office of the Commissioners of Patents, with his Petition, on the
17th May 1862.
I, JOHN CHRISTOPHER GORE, of Jamaica Plain, in the County of Norfolk,
State of Massachusetts, United States of America, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN BELT SHIPPERS," to be
as follows:
In my improved belt shipper, the prongs between which the belt runs, and
which serve for shifting the belt from one pulley to the other, are attached to
form part of a moveable plate or bar, which works in fixed guides, and is
moved to and fro therein by means of a hand lever, which is connected by a

page_text: rod or link to one end of a double bell crank or inverted T lever, which turns
on a stud fixed in the moveable or sliding bar or plate. This latter, when
shifted in either direction, is held in the required position by means of a spring
catch, which takes into one of two notches made in the edge of the sliding bar
or plate. The horizontal arms of the inverted T lever are made to bear
against the end of the spring catch, and when the sliding bar is pulled in either
direction by the hand lever, the arm of the T lever will force out the spring
catch from the notch and allow the sliding bar to move. In some cases it will
be found convenient to move the sliding plate or bar by means of a cord
passed over-suitable pullies, instead of using the-hand lever for the purpose, as
above-mentioned..
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said John Christopher Gore in the Great Seal Patent Office, on
the 17th November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
CHRISTOPHER GORE, of Jamaica Plain, in the County of Norfolk, State of
Massachusetts, United States of America, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Christopher Gore, Her special license, that I, the said John Christo-
pher Gore, my executors, administrators, and assigns, or such others as I, the
said John Christopher Gore, 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 "IMPROVE
MENTS IN BELT SHIPPERS," upon the condition (amongst others) that I; the
said John Christopher Gore, 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.

page_text: NOW KNOW YE, that I, the said John Christopher Gore, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, 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 "Improvements in Belt Shippers" relates to a certain
novel arrangement of parts for throwing the driving belts of machinery into
and out of action. The apparatus consists of an oscillating double elbow or.
inverted T-piece in combination with a single spring locking pawl. A two-
notched slide carries the belt guide, and is provided with a lever or its equiva-
lent, whereby, when the slide has been locked by the pawl with the guide in.
either of its two positions for guiding the belt, the pressure applied to the lever:
or its equivalent to shift the slide for shipping or shifting the position of the
belt from its fast to its loose pulley, or vice versâ, will first cause the unlocking.
of the slide, and then give the latter the proper endway movement. When
the movement of the slide has been given, it will be again locked, and remain
so locked until the pressure on the lever is reversed.
The Figure in the accompanying Drawing represents a front view of one of
my improved belt shippers.
A, A, is a board, or plate, or any stationary support on which all the parts of
the belt shipper are fixed; guides B, B', are attached to the board A for the
reception of the moving slide C. The two horns a¹, a¹, which constitute the
belt guide or fork, form one piece with the slide C. At the middle of the
length of the slide C, and near the lower edge thereof, is a fulcrum pin b, on
which the oscillating double elbow or inverted T-piece D is mounted, so that
it will be free to oscillate thereon. In the lower edge of the slide C, near the
ends of the two lower arms d, d', of the double-elbow piece, are two square
notches c, c', for the reception of a square pointed tooth e of the locking pawl E,.
which is attached by a pivot f to a plate F screwed to the stationary plate A,
and which is constantly pressed upward by a spring 9. The slide C near its
upper edge is provided with stops h, h', which stand at opposite sides of the
upper arm of the double elbow or T-piece D. These stops h, h¹, are
intended to limit the movement of the piece D. The tooth e of the pawl E is
thick enough to project from the notches c, c¹, in the slide under the bottom of
the double elbow piece D. The guides B, B', are so placed as to serve as
stops to the horns a, a', for the purpose of limiting the horizontal movement
of the slide C, so that such movement may only be sufficient to ship the belt.
from one pulley to the other. G is a hand lever for shifting the position of,

page_text: the slide C when required. It is pivoted at one end by a fulcrum pin to the
support A, and is connected by a rod H with a stud d' secured on the upper
arm of the double elbow or T-piece D:
The Drawing represents the slide C and belt guide a, a', as shifted to the
right, the slide C being locked by the tooth e of the pawl entering the notch c.
The operation of the shipper is as follows:-To shift the slide to the left, the
hand lever G is moved in that direction. The effect of the first part of this
movement of the lever is by the action of the rod II on the upper arın d³ of
the double elbow or T-piece D, to cause the latter to vibrate on its centre
pin 6, whereby the depression of the arm d of the elbow piece upon the tooth e
of the pawl E is effected, and the tooth e is thereby disengaged from the
notch c in the slide C. This slide being now unlocked, the continued move-
ment of the hand lever G will (by the upper arm d² of the piece D coming in
contact with the stop h) move the slide C to the left, until the horn a' by
coming in contact with the guide B, will prevent the further movement of the
slide. The notch c² of the slide C will now have arrived over the tooth e of
the pawl E, and the spring g, by its upward pressure on the pawl E, will cause
the tooth e to enter the notch and lock the slide in the new position. To
return the slide and its belt guides to the position shewn in the Drawing, the
hand lever G is to be moved to the right, and in such movement it draws the
upper arm of the piece D with it as far as the stop h¹, and so causes
the armi d' of the T-piece D to depress the tooth e of the pawl E, and unlock
the slide. The continued movement of the lever (by pressing the arm d³
ngainst the stop h¹) causes the slide to move to the position shewn in the
Drawing, when the horn a¹ of the belt guide on coming in contact with the
guide B', the slide will be stopped with the notch cover the tooth e of
the pawl E. The spring g, by its upward pressure on the pawl, will then cause
the tooth e to enter the notch c and lock the slide as before.
Instead of moving the slide by the lever G and rod H, two cords may be
attached to the arm d' of the elbow piece D, and made to pass over pulleys
arranged in the guides B, B¹. These cords (which are shewn in red in the
Drawing) may be left to hang down to a convenient position, and by pulling
the right-hand cord the same effect is produced as by moving the hand lever G
to the right, and by pulling the left-hand cord the same effect is produced as
by moving the hand lever to the left.
Having now described my Invention of Improvements in Belt Shippers,"
and having explained the manner of carrying the same into effect, I claim as
my Invention, the arrangement of the oscillating double elbow or T-piece D

page_text: and the locking pawl E in combination with the notched slide C and the
lever G or its equivalent for moving the slide to and fro.
In witness whereof, I, the said John Christopher Gore, have hereunto set
my hand and seal, the Twelfth day of November, in the year of
our Lord One thousand eight hundred and sixty-two.
