Improvements in or connected with Appliances or Devices for
Replacing Belts on Pulleys,
I, AUGUST REICHWALD, of 9, New Broad Street, in the City of London, Steel,
Iron, Metal and Mineral Merchant, do hereby declare the nature of this invention
(a communication to me from abroad by the Firm of Fried Krupp, of Essen, in
the Empire of Germany, Cast Steel Manufacturers), to be as follows:
The belt replacing device which forms the subject of this invention is composed
of substantially the following parts, namely, a wooden rod, a sleeve adapted to be
fastened or carried upon this rod, an arm moveably jointed to the end of the
sleeve, and a replacing part. A support or crutch may also be moveably con-
nected to the end of the arm.
The joint which is arranged between the sleeve and the arm allows the arm to
make a limited movement, whilst the replacing part is also pivotally carried by
the joint pin which connects the arm and the support together.
The replacing part consists or is composed of two superposed leather plates with
a stiffening insertion of strip iron and also with a thin rubber covering, and it
serves for the purpose of placing the belt upon the belt pulleys. The belt
replacing device is supported by means of the support or crutch being placed
against the shaft of the belt pulley. For this purpose a fork is provided on the
end of the support and is furnished with a rubber lining. The length of the
support or crutch is adjustable and is adjusted in accordance with the diameter of
the belt pulley in such a manner that when the belt replacing device is
supported by the support or crutch bearing against the pulley shaft, the replacing
part will bear exactly against the periphery of the belt pulley. The employment
of the support or crutch which is connected in a readily removable manner to the
belt replacing part, is only necessary in those cases where it is required to replace
wide and heavy belts.
The
When a belt is to be replaced upon a revolving pulley, the length of the sup-
port or crutch is adjusted to suit the diameter of the pulley, and the replacing
part is adjusted with the fork of the support against the pulley shaft.
replacing part is then brought between the running on part of the belt and the
belt pulley, and the belt is brought against the periphery of the pulley, and the
replacing part is pressed against the periphery of the pulley. The rubber covering
of the replacing part then adheres both to the pulley and also to the belt which is
to be replaced, so that the revolving belt pulley will carry round with it, the
replacing part together with the belt. As in the meantime the operator does not
let go of the rod, the apparatus will bend in its joints. The belt which has now
been mounted upon the belt pulley will release the replacing part after the latter
has travelled with the belt pulley through an arc of about 180 degrees.
In the case of narrow belts, the belt replacing device may be employed without a
support or crutch as already stated above. In the case of belt pulleys in which

page_text: the belt runs on from above, the pivotted arm may also be dispensed with. In
that case the replacing part is arranged directly in a pivottal manner on the
sleeve which is correspondingly lengthened and which is made of a curved shape.

Improvements in or connected with Appliances or Devices for
Replacing Belts on Pulleys.
I, AUGUST REICHWALD, of 9, New Broad Street, in the City of London, Steel,
Iron, Metal and Mineral Merchant, do hereby declare the nature of this invention
(a communication to me from abroad by the Firm of Fried Krupp, of Essen, in
the Empire of Germany, Cast Steel Manufacturers), and in what manner the same
is to be performed to be particularly described and ascertained in and by the fol-
lowing statement:-
The belt replacing device which forms the subject of this invention is com-
posed of substantially the following parts, namely; a wooden rod, a sleeve adapted
to be fastened or carried on this rod, an arm movably jointed to the end of the
sleeve, and a replacing part.
In order that the said invention may be readily understood, the same will be
described with reference to the accompanying drawings, whereon Fig. 1 is a side
view of the belt replacing device, or belt shipper, according to this invention.
Fig. 2 is a corresponding plan view, and Fig. 3 is a side view of the replacing
or shipping blade detached and drawn on a larger scale than the previous figures.
Fig. 4 shews a modified form of construction of the belt replacing device or belt
shipper in side view.
The belt replacing device or belt shipper as illustrated in Figs. 1 to 3 consists
of the wooden rod H, having the sleeve A mounted thereon, the arm B pivottally
connected to the said sleeve, and the replacing or shipping blade C. The arm B
may also have a support as D pivotally connected therewith.
The sleeve A is attached to the wooden rod H in any convenient or suitable
manner, and in the present instance the attachment is effected by means of a
binding ring. The bent arm B is connected to the sleeve A by means of a hinge
which permits of a limited motion of the arm B in the direction of the arrow.
At the upper end of the arm B is attached the support D by means of a pivot
pin E on which it is free to turn, and which also carries the shipping blade C.
The shipping blade C consists of a flat iron core, integral with the pivot pin E,
and of an elastic blade, through the centre of which the iron core passes.
These
In the present instance, as shewn at Fig. 3, the elastic blade is formed from
several plies of rubber interspersed with layers of some stout woven fabric.
layers of woven fabric are for the purpose of taking up the drag of the driving
belt upon the rubber during the shipping operation and for imparting greater
rigidity and strength to the blade. The elastic blade may however be made of
any other suitable material for example it may be formed from two superposed
sheets of leather covered with a thin coating of rubber.
This shipping blade C is for the purpose of bringing the belt onto the pulley,
and in order to prevent the belt from springing off the blade a lateral finger F
is provided.
By means of the support D the belt replacing device is held against the driving

page_text: shaft, for which purpose the free end of the support is provided with a rubber
covered fork K. The length of this support D is adjustable and is adjusted
according to the diameter of the belt pulley so that when the shipper is applied
to the driving shaft the shipping blade shall lie flush with the periphery of the
pulley.
The support D which can be easily detached from the belt shipper is only
necessary when dealing with wide and heavy belts.
If it is it desired to ship a belt onto a pulley in motion, the length of the
support D is first adjusted to correspond with the diameter of the pulley, and the
shipper applied to the driving shaft by means of its fork K. The blade of the
shipper is then inserted between the belt and the pulley and the belt is guided
to the periphery of the pulley and the blade pressed against it. The flexible
portions of the rubber blade C on either side of the iron core are caused to lie
flat against the upper surface of the pulley by the drag of the belt and by reason
of their high degree of adhesion hold firmly to both belt and pulley, and. as the
belt pulley revolves it carries round with it both belt and blade. During this time
the workman holds the rod H fast, and the arm B rocks on its pivot. The belt
now shipped upon the pulley carries the blade C round for about 180° and then
releases it.
For small belts, as has already been mentioned above, the shipper may be used
without a support.
For belt pulleys where the belt runs from overhead the pivotted arm B may be
dispensed with. In such case, and as shewn at Fig. 4, the shipping blade C is
directly and pivotally connected to the sleeve A which is correspondingly
lengthened and curved to suit the circumstances.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is;-
-
1. A belt replacing or shipping device or appliance, consisting of a rod H, with a
sleeve attached thereto and a pivotted arm B connected to said sleeve, said
pivotted arm B carrying at its extremity a rotating shipping blade C and a sup-
port D adjustable in the direction of its length, substantially as and for the
purposes set forth_
2. A shipping blade for belt shippers or replacing devices, consisting of a flat
metal core and a blade of flexible and highly adhesive material surrounding said
core, substantially as described.
3. The general construction and arrangement of parts composing the improved
appliances or devices for replacing or shipping belts or pulleys, all combined and
acting substantially as and for the purposes described with reference to the
accompanying drawings.
