I WILLIAM ROBERT LAKE of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
:-
This invention comprises an improved transporting device serves to pass the treated
material at any desired speed to the cylinders of bolting and other machinery. For
this purpose I dispense entirely with feeding blades of helicoidal shape but use instead
thereof straight rails or blades placed parallel to the cylinder axis. Such fixed rails
are each connected with a movable one by means of a number of plates, which are
pivoted to bolt rails and provided with upright flanges.
These flanges form the throwing wings of the bolting or other machine as they
throw the material to be treated toward the inner circumference of the cylinders.
When the flanges are placed parallel to the fixed rail, no progress of the material will
be obtained through the length of the cylinder, as the wings will simply leave the
material in a circle around the cylinder axis. But any oblique position of those
flanges will cause the material to be thrown in a helicoidal direction towards the
periphery of the cylinder, and as the degree of obliquity may easily be changed by
displacing the movable rail to which all the connecting plates are pivoted, any desired
pitch of such screw or helicoid may be obtained, thus varying the progress of the
material through the cylinder.

An Improved Conveyor or Transporting Device for Use in Bolting
and similar Machines.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex 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 an improved device, for conveying granular material
especially adapted for bolting machinery and has for its object to pass the treated
material to the cylinders of bolting or other grain treating or similar machinery with
any desired speed.
For this purpose I dispense entirely with feeding blades of helicoidal shape, and use
instead thereof straight rails placed parallel to the axis of the cylinder. Such fixed
rails are each connected with a movable one by means of a number of plates, which
are pivoted to both rails and provided with upright flanges or blades.
These blades form the throwing wings of the bolting reels or other machinery as
they throw the material to be treated towards the inner circumference of the
surrounding cylinders. When the blades are placed parallel to the fixed rail, no
progressive movement of the material is obtained through the length of the cylinder,
as the wings will simply leave the material in a circle around the axis of the cylinder.
But any oblique position of those blades will cause the material to be thrown in a
helicoidal direction towards the periphery of the cylinder, and as the degree of
obliquity may easily be changed by displacing the movable rail, whereto the said
blades are pivoted, any desired pitch of such screw or helicoidal lines may be obtained,
thus varying the progressive movement of the material through the cylinder..
In order to make the invention more clearly understood, I will describe its
application, by way of example, with reference to the accompanying drawings, in
which
Figure 1 is a cross section and
Figure 2 is a longitudinal section through a bolting machine provided with my
improved conveying device.
Figures 3 to 6 show details, and
Figures 7 and 8 illustrate a mechanism for altering the position of the conveying
blades from the outside.
Similar letters refer to similar parts throughout the several views.
Instead of using feeding blades of helicoidal shape, straight rails or blades a and b
are employed. To each rail a which is securely fixed to one arm of the cross piece d,
is attached another rail a' by means of the plates c so as to form a sort of
parallel rule.

page_text: The rail a¹ is movable, but it can be fixed by the screw-bolts e guided within the
curved slit of the arms of the cross-piece d. The plates care provided with
upright flanges or blades acting as conveying agents and as throwing wings of the
bolting machine.
The degree of obliquity of the blades c¹ forming parts of a helix supposed to be
laid around the rotating cylinder towards the axis of rotation is varied according
to the position of the rail a', and the pitch of the helix thus varying the progressive
movement of the material. As long as the flanges c¹ are parallel to the rail a, no
movement of the material in the direction of the axis of the rotation will be caused by
the blades c¹, but any deviation of this parallel position will cause a variation of the
relative speed of the material.
For the purpose of varying the position of the blades during the rotation of the
device one end of each of the movable rails a¹ is fastened at s to one arm of a
cross-piece (Figures 7 and 8) guided by a key n for its axial movement on the
shaft w.
To the hub of this cross piece, extending outside of the casing of
bolting reel, is attached a ring bearing against a shoulder of the hub and connected
with the stationary bearing of the shaft to by a screw n serving to move the ring t
axially and consequently the cross piece k, which simultaneously causes the movement
of the rails a¹ and the alteration of the deviation of the blades c¹ for the above
mentioned purpose.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent I declare that what I claim is :-
First. The combination in bolting or similar machinery of a device for conveying or
transporting grain, middlings and the like formed by a series of radially projecting
and adjustable blades c', with two skeleton frames having straight parallel rails a, a
and surrounding but free from contact therewith a rotating shaft w and secured
independently thereto substantially as set forth for the purpose specified.
Second. In a device for conveying or transporting grain, middlings or the like
formed by a series of adjustable blades or wings, connected to the parallel rails of two
skeleton frames secured independently to a rotating shaft, the combination of the
rails a' with the axially movable cross-piece k, the rotating shaft w and the rails a of
the other skeleton frame firmly secured to the said shaft, substantially as and for the
purpose set forth.
