Improvements in Conveyers.
Year: 1899

page_text: 1. GOTTHARD COMMICILAU, of Magdeburg-Sudenburg, in the German Empire,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in conveyers for muddy, pasty, pul-
verized, granular and other materials.
According to the invention I construct my conveyer of a trough of semi-
circular cross section, of a rotatable shaft arranged in the centre of the said semi-
circular trough and to which scraping discs or the like are secured at suitable
intervals, and of means for reciprocating the trough and rotating the shaft.
The operation of the conveyer is effected by the forward and backward move-
ments of the trough and the rotation of the shaft with the scrapers which takes
place at each change of direction of motion of the trough so that the material
lying in the trough is pushed forward intermittently.
On the forward movement of the trough the scrapers are swung up so that
the material passes freely under the same whilst during the backward move-
ment thereof the scrapers are swung down into the trough and so push the
material in front of them. The same result is obtained if the trough is held
fixed and the shaft carrying the scrapers is moved forwards and backwards
besides being rotated.

Improvements in Conveyers.
I. GOTTHARD COMMICHAU, of Magdeburg-Sudenburg, in the German Empire,
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:-
This invention relates to improvements in conveyers for muddy, pasty, pul-
verized, granular and other materials.
According to the invention I construct my conveyer of a trough of semi-
circular cross section, of a rotatable shaft arranged in the centre of the said semi-
circular trough and to which scraping discs or the like are secured at suitable
intervals, and of means for reciprocating the trough and rotating the shaft.

page_text: The operation of the conveyer is effected by the forward and backward move-
ments of the trough and the rotation of the shaft with the scrapers which takes
place at each change of direction of motion of the trough so that the material
lying in the trough is pushed forward intermittently.
On the forward movement of the trough the scrapers are swung up so that
the material passes freely under the same whilst during the backward move-
ment thereof the scrapers are swung down into the trough and so push the
material in front of them. The same result is obtained if the trough is held
fixed and the shaft carrying the scrapers is moved forwards and backwards

In the accompanying drawing::
Figures 1, 2 and 3 are vertical longitudinal sections of a portion of a conveyer
made according to the invention, the said figures shewing the trough and scrapers
in the different relative positions:
Figure 4 is a transverse section of the conveyer:
Figure 5 is a transverse section on the line 5-5 Figure 2; and
Figure is a transverse section on the line 6-6 Figure 3.
a is the trough which is semi-circular in cross section and is extended upwards
to form the sides a¹, a¹ which carry rails b, b supported upon grooved rollers or
wheels c, c, the said rollers or wheels being rotatably mounted in U-shaped
supports, of which any suitable number may be provided and which are
bolted to a suitable bed such for example as the wood beams e, e.
f is the shaft which is arranged at about the centre of the semi-circular
trough a, the said shaft f being mounted in brackets g, g which hang from the
supports, d. h, are the scraping discs which are made of such a size that
they fit the semi-circular trough a.
The trough is shewn arranged to be reciprocated by means of the connecting
rod which is secured to one end of the said trough and to a crank which
can be rotated by any suitable means, the said means also being advantageously
utilized for rotating or oscillating the shaft f although the two can be. actuated
independently if desired.
The conveyer operates as follows, that is to say, the material being introduced
into that end of the conveyer shewn in the drawing the apparatus is started and
the scraping dises are turned upwards into the position shewn in Figure 1
and 4 and the trough is then pushed in the direction of the arrow A in Figure 1,
the crank rotating in the direction of the arrow B in the said figure. When the crank
passes the position shewn in Figure 1 the scrapers are turned downwards into the
position indicated in Figures 2 and 5 and the trough a is pulled backwards:
the backward movement of the material in the conveyer, however, is prevented by
the scrapers which retain it so that the said material moves forward relatively with
the trough a. When the crank reaches the position shewn in Figure 2 the
trough commences to move forwards again in the direction of the arrow C, the
scrapers being again raised to allow the material to pass freely under them.
On reaching the position illustrated in Figure 3 the crank again withdraws the
trough in the direction of the arrow T) and the scrapers are again dropped
so as to retain the material and prevent its passing back with the trough a. It
will thus be seen that the material is gradually and intermittently shifted
forwards relatively with the trough until it ultimately reaches the discharge
end of the same.
It will be obvious that instead of reciprocating the frough the same result
could be obtained by reciprocating the rotary shaft f whilst at the same time
intermittently rotating or oscillating it in the manner above described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed. I declare that what
I claim is: -
1. A conveyer comprising a trough having a shaft carrying seraners fitting

page_text: the said trough and of means for intermittently reciprocating the trough or
the shaft and means for intermittently rotating or oscillating the shaft, sub-
stantially as, and for the purpose, herein before described.
2. In a conveyer, the combination of a semi-circular trough having rails
supported upon rollers, of means for reciprocating the same, of a shaft rotatably
mounted at the centre of the semi-circular trough, of means for intermittently
rotating or oscillating the shaft and of semi-circular scrapers fixed upon the
shaft, substantially as hereinbefore described.
3. A conveyer consisting of the parts, combined, arranged and operating,
substantially as hereinbefore described and illustrated in the accompanying
drawing.
