IMPROVED SAFETY BELT SHIPPER.'
"
AN
This Invention of an improved safety belt shipper consists in a wrought-iron cone,
the extremity of which is prolonged so as to form a small spindle which is capable
of rotating by means of the said spindle in a brass socket or bearing, which is like-
wise capable of rotating in a wrought-iron ring.
Upon the brass socket and close to the cone herein-before referred to a wrought-
iron disk is provided, which is firmly secured by soldering to the brass socket.
The brass socket is provided with a round nut or collar screwed upon it in order
to prevent it from slipping out of the ring in which it rotates. For the purpose of
screwing on the nut or collar two flat surfaces are formed upon it diametrically
opposite to each other.
The cone and its spindle are secured by means of a nut screwed upon the spindle
itself, a brass washer is placed between the nut and the brass socket in order to prevent
them from rubbing upon one another.
The wrought-iron ring in which the brass socket rotates is situated upon a rod
or stem, which divides into two forks or branches at its lower extremity, and by
means of some small bolts of 8 millimetres diameter passing through the latter
it may be attached to a wooden handle. This stem is slightly curved on one side
for belts running vertically in order to admit of the belt being brought over the
shaft to the point where it runs on or off the pulley.
When it is desired to ship a belt which runs from a pulley below to a pulley
above, the belt should be taken on the cone and held up to the pulley while the
apparatus is pressed slightly upwards or the reverse when the belt runs from a
pulley above to a pulley below; the apparatus carrying the belt upon the cone is
then to be brought also up inside the belt behind the shaft, and the belt being

page_text: pressed upwards against the point where it should run on to the pulley, the appa-
ratus is then to be drawn downwards again in such a manner that the cone is
carried round with that side of the pulley which is to receive the belt, which is
effected by reason of the weight and tension of the latter and the consequent
friction between the cone and the pulley. By these ineans the cone is carried
round upon the circumference of the pulley from the point where the belt comes
in contact with the latter to the point where it quits it and the belt itself is shipped.
The disk merely serves to prevent the belt from running off the cone. It is
necessary that the cone and disk should be free to turn in order to protect the
belt.
A strap with a loop is provided on the stem of the belt shipper to which a cord
may be attached, so that an assistant may help to pull the belt over if it is heavy or
very tight.
The advantage in this belt shipper consists in the facilty which it affords of
putting on or shipping a belt if required while the machinery is in motion with
the greatest rapidity and safety, that is to say, without going near the pulley itself,
thus entirely obviating all danger.
The smallest belt shipper for single belts is from 30 to 65 millimetres wide, the
medium size for single and double belts from 65 to 110 millimetres wide,
the largest size of from 110 to 210 millimetres wide being only used for heavy
belting.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George Sonnenthal in the Great Seal Patent Office on the 18th Novem-
ber 1876.
GEORGE SONNENTHAL, of 85, Queen Victoria Street, London, Engineer. "AN
IMPROVED SAFETY BELT SHIPPER." A communication from abroad by Heinrich
Linderhaus, of Witten-on-the-Rhur, Germany, Engineer.
This Invention of an improved safety belt shipper consists in a wrought-iron cone
the extremity of which is prolonged so as to form a small spindle, which is capable
of rotating by incans of the said spindle in a brass socket or bearing, which is
likewise capable of rotating in a wrought-iron ring.
Upon the brass socket and close to the cone herein before referred to a wrought-
iron disc is provided, which is firmly secured by soldering to the brass socket, or it
may be left free.
The brass socket is provided with a round nut or collar screwed upon it in order
to prevent it from slipping out of the ring in which it rotates. For the purpose
of screwing on the nut or collar two flat surfaces are formed upon it diametrically
opposite to each other.
The cone and its spindle are secured by means of a nut screwed upon the spindle
itself. A brass washer is placed between the nut and the brass socket in order to
prevent them from rubbing upon one another.
The wrought iron ring in which the brass socket rotates is situated upon a rod or
stem, which divides into two forks or branches at its lower extremity, and by
means of some small bolts of proportionate diameter passing through the latter it
may be attached to a wooden handle. This stem is slightly curved on one side for
belts running vertically, in order to admit of the belt being brought over the shaft
to the point where it runs on or off the pulley.
When it is desired to ship a belt which runs from a pulley below to a pulley
above the belt should be taken on the cone and held up to the pulley, while the
apparatus is pressed slightly upwards or the reverso when the belt runs from a
pul ey above to a pulley below. The apparatus carrying the belt upon the cone is
then to be brought also up inside the belt behind the shaft, and the belt being
pressed upwards against the point where it should run on to the pulley, the

page_text: apparatus is then to be drawn downwards again in such a manner that the cone is
carried round with that side of the pulley which is to receive the belt, which is
effected by reason of the weight and tension of the latter and the consequent
friction between the cone and the pulley. By these means the cone is carried
round upon the circumference of the pulley from the point where the belt comes in
contact with the latter to the point where it quits it and the belt itself is shipped.
The disc merely serves to prevent the belt from running off the conc. It is
necessary that the cone and disc should be free to turn in order to protect the
belt.
A strap with a loop is provided on the stem of the belt shipper, to which a cord
may be attached, so that an assistant may help to pull the belt over if it is heavy
or very tight.
The advantage of this belt shipper consists in the facility which it affords of
putting on or shipping a belt if required while the machinery is in motion with the
greatest rapidity and safety, that is to say, without going near the pulley itself,
thus entirely obviating all danger.
The smallest belt shipper for single belts may be from 30 to 65 m/m wide, the .
medium size for single and double belts from 65 to 110 m/m wide, the largest size
of from 110 to 210 / wide being only used for heavy belting.
In the Drawings attached and forming part of this Specification Figure 1
represents a view of the instrument, Figure 2 a section of the same, and Figure 3 a
sketch of the operation of shipping a belt with the belt shipper. No letters of
reference are required, the Drawings sufficiently explaining themselves.
Having now described and particularly set forth the nature of the Invention and
the manner of carrying it into effect, I would have it understood that what I
claim and desire to secure in the said in part recited Letters Patent is―
First. The loose revolving pointed cone and shield or disc revolving together
or separate upon a handle or staff, for the purpose of shipping belts on pulleys,
substantially as described.
Second. The general construction and arrangement of the belt shipper, sub-
stantially as described.
In witness whereof, I, the said George Sonnenthal, have hereunto uset my hand
and seal, this Fifteenth day of November, in the year of our Lord One
thousand eight hundred and seventy-six.
