A communication from abroad by EDUARD RICHARD HERMANN POHL, of Berlin, in
the Empire of Germany, Engineer.
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street, Manchester, both in
the County of Lancaster and 323 High Holborn in the County of Middlesex,
Civil Engineer do hereby declare the nature of this invention to be as follows:-
The invention relates to a winding apparatus which can be, advantageously, not
only in large and extensive buildings, but also profitably in smaller work, designed
partly for raising building materials to the top of a building in course of construction,
also for lifting materials from a depth such as mines, for example. The winding
apparatus known and used hitherto consists of very extensive and costly apparatus,
the erection of which involves loss of time. In consequence of the difficulties
attending the erection, the amount of space required, and the cost of construction,
the winding devices known hitherto, could only be employed with advantage for
large buildings, whilst for small buildings the transport of the building materials had
to be effected by hand.
The improved apparatus is formed of an easily transportable loading platform or
frame, erected on the uppermost girders when the apparatus is being put up, and of a
peculiar winding device which is also easily transportable. This winding device is the
inost essential part of the said apparatus, and consists in combining an endless lifting
chain with two chain drums constructed in such a manner that by shifting the chain
drums towards each other, the working length of the chain is regulated so as to suit
the height to which the materials have to be lifted.
On the accompanying drawing:
Figure 1 is a side view of the winding device, the side cheeks being supposed to
have been removed.
Figure 2 a plan of the same.
Figure 3 a portion of a building in course of construction, in which the new winding
device is at work.
The longitudinal beams B fixed on the transversal beams A carry the channel
Pri 77

page_text: hars C, on which are mounted the pedestals carrying the shaft on which are the belt
pulley D, the chain sheaves E forining a chain drum E and sheaves m. The shaft
receives its motion from a portable engine or from any other suitable motor. In the
case under consideration there are seven chain sheaves E arranged on the driving
shaft, and an equal number on a shaft mounted on movable pedestals, which can be
shifted forwards or backwards on the channel, rails. An endless chain G passes over
these chain drums, namely, from the first sheave in the movable drum H to the first
sheave in the fixed drum E, from the latter to the second sheave in the drum H, and
from that to the second sheave in E, and so on, until at last the chain coming from the
seventh sheave on H passes round the seventh of the sheaves in E, and thence rises
to the height of the building, for example, in course of construction, where it is
passed over guiding rollers, and then returns to the first sheave of the movable drum. It
will be seen that owing to the possibility of shifting the sheaves H towards the
sheaves E, the chain can be slackened, as the sheaves H are brought nearer the
sheaves E, and consequently the chain is tightened, as the sheaves H are moved
further from the sheaves E.
Any suitable number of sheaves E and H may be used, in practice, however, the
number shown will be convenient so that the framing of the winding apparatus is not
too long and its erection thereby rendered awkward. The distinctive and essential
characteristics are, the lengthening or shortening of the working chain, by simply
bringing one of the chain drums nearer to or further from the other.
The usual height of a dwelling house is for instance in Berlin 21 metres and the
winding apparatus shown in Figures 1 to 3 is designed for that height. 7 sheaves
have been taken as being the most advantageous, the free distance between the chain
drums is, 3 metres, so that an adjustable length of chain equal to 3 × 7 = 21 is wound
round the said drums (Figures 1 & 2).
If the sheaves H are brought 0-6 metre nearer E the upward part of the chain is
lengthened equal to 42 metres, that is the height of a story. If the guiding rollers
are erected at the place where work is going on and the endless chain with its
scaffolding can, on erection of a frame for the rollers, be raised from a story that has
been completed, to the floor beams of a new story, the walls of which have to be
erected, the working of the new lifting appliance is complete.
The receptacles containing the building material can be attached to the lifting
chain in any manner so that they can be detached therefrom. For the lifting
materials, receptacles of the shape shown on Figures 1 to 6 are very appropriate.
Figure 4 shews in elevation and plan a receptacle for stones, bricks, etcetera.
Figure 5 receptacle for raising mortar both in elevation (side and front) and plan.
Figure 6 a portion of a lifting chain with the receptacles attached thereto.
The receptacle for stones, bricks, etcetera is formed of a back board 1 and a stiffened
bottom 2. A fastening chain 4 is fastened to the bottom 2 and it is led to a bar 5 and
ends in a hook 3. The stones or bricks are simply laid in the receptacle which is
then attached to the lifting chain by means of the hook 3, or by a small chain 7
attached to the supporting chain 4 wound round the transporting chain, Figure 7, and
provided with a plate 8. The loop of the small chain is pulled tight by the weight of
the loaded receptacle, whereby the plate 8 prevents the end of the small chain slipping
through. The receptacle is thus firmly connected with the chain but is easily removed
therefrom. When the receptacle has reached the proper height, it is slightly raised
which is sufficient to loosen the connection with the chain, because the small chain 7
if used slips down and the plate 8 falls through, thus freeing the receptacle. Whilst
the materials are being raised, the filled receptacle does not wholly hang on the lifting
chain but rests on it also in consequence of the sideway arrangement of the carrying
hooks 3, or the small chain 7 so that the stones lie against the back of the receptacle-
and the bottom 2 rests on the lifting chain so that the claw 6 in the said bottom
engages the chain and prevents sideways oscillations of the receptacle. When the
receptacle has reached the required height, the workman-seizes-it, takes it off the
lifting chain and carries it to the place of work on his back by means of a belt
fixed in a .

page_text: The mortar receptacle can be made in the shape of a bucket of conical form for the
purpose of facilitating emptying, they are likewise provided with the hook 3 and the
claw 6. The carrying chain 4 Figure 4 is not necessary here as it only serves to hold
the loaded bottom of the receptacle and is done in this case safely with the surrounding
walls of the bucket. When a small chain 7 is applied, it is fixed on the back plate
at 3. The arrangement shown in Figure 8 is more advantageous than the one
described in the foregoing. In Figure 8 the bottom is hinged to the back part of the
bucket and is held firmly by means of a bolt. When the mortar is being filled the
bottom 9 is securely fixed, when the workman has carried the mortar to the place
where it is to be employed, he pulls back the bolt which held the bottom fast, the
latter falls and the contents fall out.
In order that the guiding rollers i may be easily moved to a new story, they are
mounted on a frame when the material is raised outside the building, which can be
erected on a platform and supported by struts bracing it to the wall.
This loading platform stands out from the wall so that the chain G of the winding
apparatus runs to and from it whilst the workman can stand on the loading platform,
take the receptacles full of material from the chain, and hang the empty ones thereto.
If materials are to be raised inside a building, the framing simply rests on the floor
beams, and the loading platform is omitted. As for the device for shifting of the
chain rollers H, its construction can be of any kind provided with screw, rack, or
chain gear. Chain gearing is, however, the most practical, as other mechanisms are
costly and wear away more quickly, etcetera. A practical device for the fixing of the
roller is for instance the following.

For the purpose of shifting the chain sheaves H their shaft ends are provided with
rollers (Figure 1) permitting its movement on the channel rails, there are on the
said shaft on both sides of the sheaves H pieces provided with hooks with which
both ends of the chain are connected. The chain runs from the piece k over the
loose sheave m of the shaft E to the fixed sheave n of a winch F and thence back to
piece k.
It is then advantageous to mount the winch F on the channel rails. The shaft, O of
the fixed winch chain sheaves n is connected with the gear of the winch F, so that
according to the direction in which the crank is turned (Figure 2) the sheaves H
are brought nearer E, or moved further apart. A pawl device on the winch maintains
the position of the sheaves H with reference to the sheaves E.
The sheaves H, or at least some of them can be loose on their common shifting
shaft, and separated from each other. The arrangement of the sheaves E can be very
similar.
The apparatus described in the foregoing can also be erected on a carriage which
can remain under the apparatus. This arrangement of this apparatus renders it more
easy to move, and renders repairs more easy.
In the foregoing description the lifting chain was led from the apparatus directly
upwards to the place of delivery of the building materials, this required that the
apparatus be placed under the said place of delivery. When a waggon is einployed to
support the winding device or under special conditions of construction, it may happen
that this is not possible. In such cases the transporting chain can be led horizontally
up to the spot immediately under the unloading place and thence upwards on guiding
rollers. In lifting materials from a depth, the winding apparatus must, of course, be
erected at the height at which the extracted material is to be delivered, and the
guiding rollers are fixed on a suitable framing at the bottom of the place of extraction.
In other respects the winding apparatus remains substantially the saine.

the Empire of Germany, Engineer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street Liverpool and 6, Bank Street, Manchester both in the
County of Lancaster & 323 High Holborn in the County of Middlesex, Civil
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:—
The invention relates to a winding apparatus which can be used advantageously,
not only in large and extensive buildings, but also profitably in smaller work. The
apparatus is designed partly for raising building materials to the top of a building in
course of construction, and also for lifting materials from a depth, such as in mines,
for example. The winding apparatus known and used hitherto consists of very
extensive and costly apparatus, the erection of which involves loss of time.
consequence of the difficulties attending their erection, the amount of space required
for them, and the cost of their construction, the winding devices known hitherto,
could only be employed with advantage for large buildings, whilst for small buildings
the transport of the building materials had to be effected by hand.
In
The improved apparatus is formed of an easily transportable loading platform or
frame, erected on the uppermost girders when the apparatus is being put up, and of a
peculiar winding device which is also easily transportable. This winding device is the
most essential part of the said apparatus, and consists in the combination of an
endless lifting chain with two chain drums constructed in such a manner that by
shifting the chain drums towards each other, the working length of the chain is
regulated so as to suit the height to which the materials have to be lifted.
Referring to the drawings filed with the provisional specification
:-
Figure is a side view of the winding device, the side cheeks being supposed to
have been removed.
Figure 2 a plan of the same.
Figure 3 a portion of a building in course of construction, in which the new winding
device is at work.
The longitudinal beams B fixed on the transversal beams A carry the channel bars C,
on which are mounted the pedestals carrying the shaft on which are the belt pulley D,
the chain sheaves E forming a chain drum E and sheaves m. The shaft receives its
motion from a portable engine or from any other suitable motor. In the case under
consideration there are seven chain sheaves E arranged on the driving shaft, and an
equal number on a shaft mounted on moveable pedestals, which can be shifted forwards
or backwards on the channel rails. An endless chain G passes over these chain drums,
namely, from the first sheave in the movable drum H to the first sheave in the fixed

page_text: drum E, from the latter to the second sheave in the drum H, and from that to the
second sheave in E, and so on, until at last the chain coming from the seventh sheave
on H passes round the seventh of the sheaves in E, and thence rises to the height of
the building, for example, in course of construction, where it is passed over guiding
rollers i, i, and then returns to the first sheave of the movable drum. It will be seen
that owing to the possibility of shifting the sheaves H towards the sheaves E, the
chain can be slackened, as the sheaves H are brought nearer the sheaves E, and
similarly the chain is tightened, as the sheaves H are moved further from the
sheaves E.
Any suitable number of sheaves E and H may be used, but in practice, however,
the number shown will be convenient so that the framing of the winding apparatus is
not too long and its erection thereby rendered difficult. The distinctive and essential
characteristics are, the lengthening or shortening of the working chain, by simply
bringing one of the chain drums nearer to or further from the other.
The usual height of a dwelling house is, for instance, in Berlin, 21 metres, and the
winding apparatus shown in Figures 1 to 3 is designed for that height. 7 sheaves
have been taken as being the most advantageous, the free distance between the chain
drums is 3 metres, so that an adjustable length of chain equal to 3 × 7 = 21 is wound
round the said drums (Figures 1 & 2).
If the sheaves H are brought 0.6 of a metre nearer to E the upward travelling part
of the chain is lengthened to an amount equal to 4.2 metres, that is to the height of a
story. If the guiding rollers i be erected upon a suitable frame mounted upon a
scaffolding at the place where work is going on, then the endless chain with the frame
and scaffolding can be raised from a story that has been completed, to the floor beams
of a new story, the walls of which have to be erected, so that the working of the new
lifting appliance can proceed continuously with the exception of a few trifling
interruptions.
The receptacles containing the building material can be attached to the lifting
chain in any manner so that they can be detached therefrom.
For the lifting of building material, receptacles of the shape shown on Figures 4
to are very appropriate. Figure 4 shows in elevation and plan a receptacle for
stones, bricks, etcetera, and Figure 5 receptacle for raising mortar, both being in
elevation (side and front) and plan.
Figure 6 a portion of a lifting chain with the receptacles attached thereto.
The receptacle for stones, bricks, etcetera, is formed of a back board 1 and stiff
bottom 2. A suspension chain 4 is fastened to the bottom 2 and it is led to a bar 5
and ends in a hook 3. The stones or bricks are simply laid in the receptacle which is
then attached to the lifting chain G by means of the hook 3, or by a small chain 7
Figure 7, which is attached to the suspension chain 4, is wound round the lifting
chain 7, and is provided with a plate 8. The loop of the small chain is pulled tight
by the weight of the loaded receptacle, and the plate S prevents the end of the small
chain slipping through. The receptacle is thus firmly connected with the chain, but is
easily removed therefrom. When the receptacle has reached the proper height, it is
slightly raised, and this raising is sufficient to loosen the connection with the lifting
chain, because the small chain 7 (if used) slips downwards, and its loop becoming
thus enlarged, the plate 8 falls through the latter, and the receptacle is freed. Whilst
the materials are being raised, the filled receptacle does not hang vertically from the
lifting chain, but rests upon it in consequence of the carrying hook 3, (or the small
chain 7) being arranged in one side of the receptacle. The stones, or bricks, thus lic
against the back of the receptacle and the bottom 2 rests on the lifting chain so that
the claw 6 in the said bottom engages the chain and prevents lateral oscillations of the
receptacle. When the receptacle has reached the required height, the workman seizes
it, takes it off the lifting chain and carries it to the place of work on bis back by
means of a belt fixed in a a.
The mortar receptacles can be made in the shape of a bucket of conical form for
the purpose of facilitating emptying, these buckets being likewise provided with a
hook 3 and claw 6. The suspension chain 4, Figure 4, is not necessary here as it only
