PROVISIONAL SPECIFICATION.
Improvements in Conveyers for Conveying Granular and such like
Material.
I, JOHN LAIDLAW, of the Firm of Wasson Laidlaw & Company, of 98 Dundas
Street, (South) Glasgow, North Britain, Engineers, do hereby declare the nature
of this invention to be as follows:-
:-
This invention relates to improvements in conveyers for carrying along granular
or such like material, for which purpose endless bands, screw conveyers or the like
have been employed.
In carrying out my invention I employ an open trough or gutter without screws
or spirals. This trough is supported by hinged rods which are set at a slight
inclination to the vertical. The trough is connected to a crank shaft by a
connecting rod. The crank shaft is driven by a pulley and belt. This gives a
quick oblique vibratory motion to the trough, which causes the material to move
rapidly along. The trough may be suspended by rods or hinged bars, or it may
be slung in chains or their equivalent.

Improvements in Conveyers for Conveying Granular and such like
Material.
1, JOHN LAIDLAW, of the Firm of Watson Laidlaw & Co. of 98 Dundas
Street, South, Glasgow, North Britain Engineers, 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 improvements in conveyers for carrying along granular
or such like material, for which purpose endless bands, screw conveyers, or the like
have been employed, and has special reference to improvements in that form of
conveyer which is made with an open reciprocating trough and supported by
oblique springs.
In carrying out my invention I employ an open trough or gutter without screws
or spirals. This trough is supported by hinged rods which are set at a slight
incliuation to the vertical. The trough is connected to a crank-shaft by a
connecting-rod. The crank shaft is driven by a pulley and belt. This gives a
quick oblique vibratory motion to the trough, which causes the material to move
rapidly along. The trough may be suspended by rods or hinged bars, or it may be
slung in chains or their equivalent.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawing showing several
methods of carrying out my invention.
Figures 1, 2, and 3 are longitudinal elevations.
and are a sections

page_text: I use an open trough A, which is partly supported by hinged rods B, Figure 1,
or hung by hinged rods B, Figure 2, or chains B, Figure 3, and partly supported
by a connecting-rod C, and crank-shaft D. The length of the crank-shaft is
adjusted so that the rods or chains are set at a slight inclination to the vertical.
The crank-shaft is driven by a pulley E and belt. The motion of the crank-shaft
transmitted through the connecting-rod gives a quick backward and forward and
up-and-down motion to the trough, which causes the granular material to move
rapidly along.
Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed, I declare that what
my said
I claim is :-
The improved conveyer for conveying granular or such like material, consisting
of an open trough supported or suspended by jointed, hinged, or pivoted rods or
chains, to which a quick oblique vibratory motion can be given, as and for the
purposes described.
