A communication from HERMANN KOBERT LEICHSENRING, of Schoenebeck on ue, in
the German Empire, Engineer.
1, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.
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 -
While narrow and loosely stretched belts may be passed onto their pulleys by means
of a rod or a pole, or any other suitable simple means this is not possible with broad
and tightly stretched belts when they are to be passed onto the pulley.
The object of the present invention is to design an apparatus for belting pulleys
which carries and guides the belt without any danger of being carried away by it
when the machinery is in motion. This apparatus consists essentially of four parts
ie. of the handle of the bent arm fixed on the end of the handle, of a pawl lever in
the interior of the bent arm, and of a head with a belting pin which head is fastened
to a steel ribbon, and can be removed from the rigid bent arm to avoid accidents.
In the accompanying drawings:
Fig. 1 represents a longitudinal section of the bent arm fixed to the end of the
handle with the head and the pawl lever.
Fig. 2 an elevation of the back of the apparatus.
Fig. 3 a cross section of the head with the adjustable belting pin on line A B of
figure 1.
Fig. 4 a cross section of the bent arm with the pawl lever on line CD of figure 1.
The bent arm a fixed to the handles by means of the socket H has a groove on its
face for the reception of the pawl lever pivotted at e. In the back of the bent arm a
is formed an opening through which passes the pawl of the lever . At the
extremity of the bent arm a its back bends down between the sides to a forming thus
a pocket or chamber for the reception of the tail end of the head b.
The tail end b' of the head bis rivetted to the steel ribbon d which slides in suitable
guides a¹ a a³ a on the back of the bent arm if the position of the pawl f¹ permits it

page_text: and this will be the case when the elongated part 2 of the lever is pressed towards
the handles in the direction of the arrow. The pawl will then he lifted from the
back of the bent arm, and the lugs or projections d' d' d³ fixed to the steel ribbon will
be enabled to pass under the pawl" thus permitting the head to be removed from
the bent arm a. The distance between the lugs of the steel ribbon corresponds to the
distance the head may be removed from the bent arm.
When the lever presses against the shaft W of the pulley which is to be belted
the pawl will be lifted and the lugs of the steel ribbon liberated, the head may
then follow the movement of the pulley if necessary in the direction of the arrow. If
necessary the steel ribbon may wholly be drawn out from its guide at to a' but this
cannot be done without first removing the hook at the end of the steel ribbon d.
The rivet n is therefor made so slight or of such soft material that it does not resist a
tractive power which may be dangerous to the operator and break the apparatus.
When horizontally running belts are to be passed on to the pulley the head is very
often not removed at all from the bent arm, but it may be so by depressing the lever/2
by means of the pivotted lever shown in dotted lines in figure 1.
To enable the apparatus to belt a pulley either from the right hand or left hand side
according to which side the belt is hanging, the belting pin c of the head is provided
with a groove c¹ and sockets e² at the ends of the groove. By depressing the stud h
the pin is sufficiently depressed to remove it from one of the sockets c² and slide the
pin c to the other side until the pin enters the socket 2 of the other side.
The above described apparatus has the advantage that it can be used both for
vertically running and horizontally running belts.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondent and in what manner the same is
to be performed 1 declare that what I claim is :-
1. In apparatus for belting pulleys a steel ribbon such as d provided at its end with
a head such as band belting pin such as cand drawn out automatically from the
apparatus by the tension of the belt substantially as and for the purpose described and
illustrated in the accompanying drawings.
2. In apparatus for belting pulleys a pawl lever such as holding the steel ribbon
by one of the lugs fastened thereto, and capable of being lifted to enable the head and
the steel ribbon to be removed from the apparatus substantially as and for the purpose
described and illustrated in the accompanying drawings.
3. In apparatus for belting pulleys a rigid bent arm such as a forming on its end a
chamber or pocket for the reception of the tail end of the head and the guiding of the
steel ribbon substantially as and for the purpose described and illustrated in the
accompanying drawings.
4. In apparatus for belting pulleys a belting pin such as e provided with a longi-
tudinal groove and two sockets substantially as and for the purpose described and
illustrated in the accompanying drawings.
5. In apparatus for belting pulleys the employment of stud and pin ¹ to lock and
unlock the belting pin in the head by means of a spring substantially as and for the
purpose described and illustrated in the accompanying drawings.
6. In apparatus for belting pulleys the employments of weak rivets to enable the
tractive power to break them easily if necessary to wholly remove the steel ribbon and
the head from the apparatus to avoid danger substantially as and for the purpose
described and illustrated in the accompanying drawings.
