Improved Means for Transporting Bodies in Horizontal and
Inolined Directions.
•
I, MAX ZAHN of Artern, Thuringia, Germany, Director of Works, do hereby
declare the nature of this invention to be as follows:-
- The means heretofore employed for transporting solid bodies in a horizontal
direction are unsuitable in many cases, in view of the necessary mechanisms and
local conditions, in which cases simpler modes of transport appear to be desirable.
My present invention relates to a very simple means of transport 'which is
applicable under all conditions, and for the working of which very simple
-appliances will suffice.
The invention consists in the application of the property of bodies to tend to
romain in a state of rectilinear uniform motion by virtue of their inertia, and it is
based on the observation that a body which is moving forward at the same uniform
speed as the support on which it rests, will not participate in the motion of the
latter when it is suddenly moved in the contrary direction at a quicker speed.
This action may be readily observed if for example, a sheet of paper or other plane
surface A Figure 1 of the accompanying drawings, on which rests a body B, be
moved slowly from the horizontal position 1, for instance, in the direction of the
arrow, into the position II, and ba then suddenly and rapidly moved back into the
position I again. The body B will not partake of such backward motion but will.
remain more or less stationary in its position II, and on the completion of such
backward motion of A it will occupy the position B' thereon, consequently the
body B will have been transported the distance B-B' in the direction of the
arrow,
By repeating the above described action, the body can of course be transported
any desired distance, as shewn by the positions IV. V and VI.
It will be seen that for practically applying this means of propulsion, it is only
necessary to connect the support A with a mechanism that will impart motion
thereto in the direction of transport at a uniform and moderate speed and will thon
move the support more rapidly in the contrary direction. It is not absolutely
necessary that the changes of direction of motion shall take place suddenly; it is
only advantageous for the conditions of continuous working. The support A night
also remain at rest for a certain time in the position II. In this case the backward
inotion would have to be much more rapid than otherwise, because the moment of
inertia will in that case be much less than in the case where the body, at the time
of reversal, still has a motion in the advancing direction.
Mechanisms having such a description of to and fro motion are well known, and
their connection with the support by which the body is to be transported gives rise
to no difficulty; both parts may be variously arranged.
The nature of the support A will of course have to be determined according to
the nature of the body to be transported; it may be a baud, board, trough, tube,
or box, or other receptacle.
With regard to the surface of the support, it is of course desirable to make it an
smooth as possible when the transport takes place in the horizontal direction, but
this is not absolutely necessary, as even a considerable amount of frictional
resistance can be overcome by a sufficiently rapid backward motion when the
surface is rough.
When the transport has to be effected in an upward direction (which is of course
only possible up to a certain limit) as also when it takes place in a descending.
direction, the support may be advantageously formed with a serrated surface.

page_text: The transport can be perfectly continuous, as without reference to the direction
of motion of the support, whether forwards or backwards, frosh material can always
be fed on to it.

COMPLETE SPECIFICATION.
Improved Means for Transporting Bodies in Horizontal and
Inclined Directions.
I, MAX ZAHN, of Artern, Thuringia, Germany, Director of Works, 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 means heretofore employed for transporting solid bodies in a horizonta!
direction are unsuitable in many cases, in view of the necessary mechanisms and
local conditions, in which cases simpler modes of transport appear to be
desirable.
My present invention relates to a very simple means of transport which is
applicable under all conditions, and for the working of which very simple appliances
will suffice.
The invention consists in the application of the property of bodies to tend to
remain in a state of rectilinear uniform motion by virtue of their inertia, and it is
based on the observation that a body which is moving forward at the same uniform
speed as the support on which it rests, will not participate in the motion of the latter
when it is suddenly moved in the contrary direction at a quicker speed. This action
may be readily observed if for example, a sheet of paper or other plane surface A
Fig. 1 of the drawings accompanying my Provisional Specification, on which
rests a body B, be moved slowly from the horizontal position I, for instance, in the
direction of the arrow, into the position II, and be then suddenly and rapidly
moved back into the position I again. The body B will not partake of such
hackward motion but will remain more or less stationary in its position II, and on
the completion of such backward motion of A it will occupy the position B'
thereon, consequently the body B will have been transported the distance B-B¹
In the direction of the arrow,
By repeating the above described action, the body can of course be transported
any desired distance, as shewn by the positions IV, V and VI.
It will be seen that for practically applying this means of propulsion, it is only
necessary to connect the support A with a mechanism that will impart motion
thereto in the direction of transport at a uniform and moderate speed and will then
move the support more rapidly in the contrary direction. It is not absolutely
necessary that the changes of direction of motion shall take place suddenly; it is
only advantageous for the conditions of continuous working. The support A
might also remain at rest for a certain time in the position II. In this case the
backward motion would have to be much more rapid than otherwise, because the
moment of inertia will in that case be much less than in the case where the body,
at the time of reversal, still has a motion in the advancing direction.
Mechanisms having such a description of to and fro motion are well known, and
their connection with the support by which the body is to be transported gives rise
to no difficulty; both parts will of course have to be determined according
be variously arranged.
The nature of the support
to the nature of the body to be transported; it may be a band, board, trough,
tube, or box, or other receptacle.
With regard to the surface of the support, it is of course desirable to make it as
smooth as possible when the transport takes place in the horizontal direction, but
"

page_text: this is not absolutely necessary, as even a considerable amount of frictional
resistance can be overcome by a sufficiently rapid backward motion when the
surface is rough.
When the transport has to be effected in an upward direction (which is of course
only possible up to a certain limit) as also when it takes place in a descending
direction, the support may be advantageously formed with a serrated surface.
The transport can be perfectly continuous, as without reference to the direction
of motion of the support, whether forwards or backwards, fresh material can
always be fed on to it.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declaro that what
I claim is :-
Transporting bodies in horizontal or inclined directions on a suitable transporting
medium, such as a band, board, tube, trough box, and the liko, by imparting to
such transporting medium a to and fro motion in such manner that when moved in
the direction in which the body situated thereon is to be transported, it is made to
travel at a uniform speed, which is less than that at which it travels in the contrary
direction, substantially as described.
