An Improved Device for Placing Belts on Pulleys.
I, GEORGE SONNENTHAL, of 85 Queen Victoria Street, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows :-
My invention relates to belt-shippers, that is to say to apparatus intended for
facilitating the passing of a belt strap or band over a drum, pulley or the like.
The object of my said invention is to provide an improved belt-shipper having a
folding or movable upper part or bar, adapted to become folded down or to give
during the shipping of the belt, so as to permit the pin of the said belt-shipper to
follow the belt on the drum or pulley to the point where contact ceases.
shipper constructed according to my said invention admits of a belt or band being
A belt-
passed over a drum, pulley or the like with much greater facility than can be
attained by belt-shippers as hitherto constructed.
In carrying my said invention into practice I provide a pole or rod of any con-
venient dimensions and formed of wood or other suitable material. The upper
extremity of this rod or pole is fitted with a metal socket to which is firmly secured
one extremity of a metal link or plate. The other extremity of this link or plate
is connected by means of a suitable joint or hinge with a similar link or plate to
which is journalled so as to be capable of rotating freely a taper pin having a
suitable flange or collar at a convenient distance from its free extremity. Any
desired number of these links or plates and intermediate joints or hinges may be
employed, the last of the said links or plates supporting the taper pin for shipping
the belt.
I prefer to construct the above mentioned joints or hinges of plates of channel
shape in transverse section and to provide on the same side thereof flat springs to
maintain the said links or plates normally in a rigid position.
The extremities of the links or plates pivoted to the said hinges or joints are
bevelled, the amount of the bevel being equal to the extent of the bearing against
he flat springs from the centre of the pivot pins or bolts.
By using a moderate amount of force the said links or plates can be turned in
he joints or hinges, the end of the flat springs which bear against them being raised
nd counteracting the motion of the links or plates in the said joints or hinges.
When the bevelled end of any of the links or plates bears throughout its full length
gainst corresponding flat spring further movement of the said link or plate in that
irection is arrested.

COMPLETE SPECIFICATION.
An Improved Device for Placing Belts on Pulleys.
I, GEORGE SONNENTIAL, of 85 Queen Victoria Street, in the City of London,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention relates to belt-shippers, that is to say, to apparatus intended for
facilitating the passing of a belt, strap, or band over a drum, pulley or the like.
According to my said invention, I make the belt-shipper hinged or jointed so that
it is adapted to fold down or yield during the shipping or placing in position of the
belt upon the drum or pulley, and thus admit of a pin or projection at its upper end
following the belt around the periphery of the said drum or pulley to the point
where contact of the belt therewith ceases. By my improved belt-shipper, there-
fore, a belt or band can be passed over a drum, pulley or the like with much greater
facility than by the belt-shippers as hitherto constructed.
In the accompanying drawing, I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a front elevation, and
Figure 2 is a side elevation of one form of my improved belt-shipper.
Like letters indicate corresponding parts throughout these two figures.
A is a pole or rod of any convenient dimensions formed of wood or other suitable
material. To the upper extremity of the rod or pole A is firmly secured, by metal
straps B or by means of a socket or otherwise, one of a series of metal links or
plates C. These links or plates C are connected or coupled to other links or
plates by means of suitable hinge-joints as indicated at C
The links or plates C' are preferably double and of channel shape in transverse
section, and the links or plates C are single and composed of flat bars. Any desired
number of the links or plates C, C' may be employed. D, D are flat springs firmly
secured to the links or plates C' and tending to maintain the links or plates C, C¹
normally in line.
The extremities of each of the links or plates C, moreover, are bevelled or cut
away as shown in Figure 1, the amount of the said bevel being equal to the extent
of the bearing against the spring D from the centre of the pivot-pin or bolt. E is
a taper pin journalled in a socket or bearing C³ firmly secured at or near the upper
extremity of the last or uppermost plate C, so as to be capable of rotating freely,
and having a suitable flange or collar E at a convenient distance from its free
extremity. The taper pin E is preferably retained in position in the socket or
bearing C³ by means of a bolt, pin or set-screw C4 engaging in a circumferential
groove in the said pin, or is otherwise arranged so as to be readily removable
therefrom.
By cutting away the ends of the links or plates C as above mentioned, I diminish
the amount of force required to cause the said links or plates to turn or pivot upon
their joints or hinges, the ends of the flat springs which bear against them being
raised and counteracting the motion thereof. When the bevelled or cut away end
of either of the links or plates bears throughout its full length against the corre-
sponding flat spring, further movement of the said link or plate in that direction is
arrested.
In using my improved belt-shipper to ship or place in position a belt or band
upon a drum or pulley upon a length of overhead line-shafting, the belt or band to

page_text: shipped is supported upon the taper pin E and is passed over the drum or pulley
in the usual way, the joints or hinges being kept stiff or prevented from yielding
too easily by the flat springs D.
round the periphery of the drum or pulley, the upper end of the belt-shipper comes
When the pin E has passed a certain distance
in contact with the shafting and one or more of the said joints or hinges in
accordance with the diameter of the said drum or pulley gives or yields (as shown
in dotted lines in Figure 1) the said taper pin following the belt or band on the said
drum or pulley to the point where contact therewith ceases.
By the employment of several links or plates and intermediate hinges or joints,
the same belt-shipper can be used with drums or pulleys of widely different
diameters.
It is obvious that I can somewhat modify the construction of my improved belt-
shipper without departing from the nature of my said invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it understood that
what I claim is :-
First. A belt-shipper which is hinged or jointed for the
pecified.
purpose above
Second. The improved belt-shipper wherein the upper part is constructed of
nks or plates connected by hinge-joints and provided with springs, substantially
s described with reference to the accompanying drawing and for the purpose
pecified.
