PROVISIONAL SPECIFICATION.
Improvements in Means or Apparatus for Regulating the Passage
of Coals or the like for Sorting, Picking, and Oleaning.
I THOMAS ARCHER Junior, of 6 Park Terrace Gateshead on Tyne in the
County of Durham, Engineer do hereby declare the nature of this invention
to be as follows :-
The object of my invention is to provide means whereby coals, or the like, are
automatically regulated as to the speed and thickness in which they pass to or
through the hopper, screen, or sorting place so that the said coals, or the like, are
presented in the manner best calculated to enable them to be sorted, picked, or
cleaned, from foreign matter. According to my invention I cause the cage which
receives the tubs of coal and which is turned over to discharge the coal, or the
like, down the passage to the sorting place (which cage is usually termed the
"kickup") to operate a door, trap, stop, or regulating shutter, so as to cause it to
open and close at the proper times. For this purpose I may use any convenient
arrangement of mechanism such as a cam on the axis of the kickup, acting on a
lever connected to the trap, or the like, or I may connect the kickup and trap, or
the like, by a cord or chain passed over a pulley, or 1 may connect the said trap,
or the like, to the kickup in any other convenient way. may regulate the motion
of the trap, or the like, by connecting it to a revolving shaft or its equivalent, at
the proper time the connection being made by the movement of the kickup.

COMPLETE SPECIFICATION.
Improvements in Means or Apparatus for Regulating the Passage
of Coals or the like for Sorting, Picking, and Cleaning.
I, THOMAS ARCHER Junior of 6 Park Terrace Gateshead-on-Tyne in the
County of Durham 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 object of my
invention is to provide means whereby coals or the like, are
automatically regulated as to the speed and thickness or depth of layer in which
they pass to, or through, the hopper, screen, or sorting place, so that the said coals,
or the like, are presented in the manner best calculated to enable them to be sorted,
picked, or cleaned, from foreign matter.
According to my invention I cause the cage which receives the tubs of coa! and
which is turned over to discharge the coal, or the like, down the pazzage to the
sorting place, (which cage is usually termed the “kickup") to operate a door, trap,
stop, or regulating shutter, so as to cause it to open and close at the proper times.
For this purpose I may use any convenient arrangement of mechanism, such as a
cam on the axis of the kickup, acting on a lever connected to the door, trap, or the
like, or I may connect the kickup and door, trap, or the like, by a cord, or chain,
passed over a pulley, or I may connect the said door, trap, or the like, to the kickup
in any other convenient way. I may obtain the motion of the door, trap, or the
like, by putting it, or a connection with it, into engagement with a revolving shaft,
or its equivalent, at the proper time, the engagement being made and unmade by
the movement of the kickup.

page_text: In order that my invention may be well understood I have illustrated in the
accompanying drawings what I consider the best ways of carrying it into effect.
In the several figures A is the "kickup" B is the sorting table, or shoot, and C is
the door, trap, shutter, or the like, operated by the movement of the kickup A.
Figure 1 shews an arrangement wherein the kickup has on the end of one (or
both) of the trunnions upon which it is supported and which turn in the supports or
bearings, a cam D which bears upon the tail of a lever E, centered at e, and
attached at the other end to the door, or shutter, C. When the kickup is returned
to its normal position after being tipped the said cam presses on the end of the
lever E and the door, or shutter C, is raised; but when the kickup is turned over to
discharge its contents the cam D is turned into such a position that it allows the
door or shutter C to descend by its own weight. Thus the door or shutter C is
closed, and opened, as the kickup is successively turned over, and back again.
The arrangement of cam and lever may be at one side, or at both sides, of the
kickup and shutter, or door.
Figure 2 shews an arrangement wherein the trunnion has a pulley F upon it to
which one end of a rope, or chain, G, is attached the said rope or chain passing
over a pulley 9 and its other end being connected to the door, or shutter C, so that
the door C is opened when the kickup is turned up, but is allowed to close when the
kickup is tipped over. This arrangement may also be at one side, or at both sides,
of the kickup, and door.
Figures 3 and 4 shew an arrangement wherein the door or shutter C has connected
to it a rack G connected by the rod g' to the arm H keyed to the trunnion of the
kickup. On a shaft I kept revolving in bearings in standards by any suitable
motor is a pinion i. When the kickup is turned over to discharge the coal (as
shewn in Figure 4) the rack Gleaves the pinion i and the door C falls. When the
kickup is returned to its original position the arm H and rod 9³ draw the rack G
into engagement with the pinion which then raises the rack and the door attached
to it as shewn in Figure 3.
In this and the other figures I have necessarily shewn only one arrangement at
one side of the kickup but generally I prefer to duplicate the arrangements at each
side of the kickup. The door or shutter C may slide in any suitable guides.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I déclare that what I
claim is :-
1. In apparatus for regulating the passage of coals, or the like, for sorting,
picking, or cleaning; means for causing the movement of the tipping cage, or
kickup, to effect the operation of the door, or shutter, or the like, substantially as
hereinbefore described.
2. The several arrangements and combinations of parts constituting apparatus for
the purposes mentioned; as hereinbefore described, and shewn in Figure 1, in
Figure 2, and Figures 3 and 4, respectively, of the accompanying drawings.
