Specification of Letters Patent.
Patented Feb. 4, 1913.
Application filed August 28, 1911. Serial No. 646,319.
To all whom it may concern:
Be it known that I, JOHN Doruwson, a subject of the King of Great Britain and Ireland, and a resident of Glasgow, Scotland, have invented a certain new and useful Im roved Riddling-Machine, of which the fol owing is the specification.
Certiiin ironmnsters require that ore delivered to them must be in a condition such that it will pass through a. given mesh. This necessitates that each tub of ore taken from the shi be first dischargedonto the quay then rid led and finally loaded into the railway wagons which are to convey it to its destination. To save the labor and consequently lessen the time and expense which this procedure entails, accordin to' this invention there is provided a riddle of an improved construction such that it will receive without damage to itself the weight of ore contained in each tub load taken from the ships hold, and so carried that while it extends over the railway ws onsinto which the material is to be loaded, the wagons may be readily moved without its being necesapertures being of such dimensions and so sary to handle the riddle.
The improved construction of riddle may also be used to discharge coal or the like from ships direct to railway wagons in a riddled condition.
In carrying out the invention there is provided a gauntree running on wheels andbeneath which the wagons can pass. Above this gauntree a riddle is $115 ended by links from the side members of t e gauntree, the 1 and breadth such that while it exten s entirely over one wagon its ends extend more or less over the wagons at each end of the one covered by the riddle. Means are provided to impart an oscillating motion to the riddle, and a. horizontal grating is preferably secured on the gaunt-rec above the center of the riddle onto whichgrating the load is first discharged to break its fall. The riddle is preferably so made that its surface slopes from the middle downward toward the ends.
An example of the improved riddle is shown on two accom unying sheets of'explsnstory drawings igure 1, Sheet'l, being a plan and Fig. 2, sheet 2, a side elevation.
As shown in the drawings there is 1'0 vided a gauntree com rising top and ottom longitudinal mem rs A A of angle.
iron on each side, the members on each side being connected together by vertical angle iron end members A", A, A, A. These end members are braced together by diagonal members B, B and transverse mom bers B, B, the latter being at such a height and of such slength that the side members are so spaced apart as to enable the gauntree to straddle a. railway wagon. The gauntree thus formed runs on wheels C, C, C, C, and above the transverse members B, B, there is suspended by links D D D, D, a. riddle of a length and'breadth such that while it extends entirely over one wagon its ends extend more or less over the wa ons at each end of the one covered by the riddle.
The riddle consists of an angle-iron frame E carrying side plates E end angleiron cross members E supportin a. to plate E, the side and cross members ieing highest at the center so that the top plate sio from the middle downward toward t e ends. Apertures E (some of which only are shown) are formed through the part of the top plate which extends over a wagon, these spaced apart as may be r uired by the mesh decided upon. The top p ate E is removably secured in place so that other plates having apertures of different size may be substituted when desired.
Above the center part of the riddle the gauntree carries a grating consisting of angle-iron bars G extending between theupper side members A and carrying bars G so spaced apart that while they not to break the fall of a load when it is discharged they do not prevent any of the material reaching the riddle.
The gsuntree carries an internal combustion engine G, s-coolin -water tank G connected with the engine y circulatin pipes G, G, a. tank H holding petrol to be supplied to the engine by a pipe (not shown) and an engine exhaust pipe H. A pinion H (shown by a dotted circle in Fig. 2) on the engine crank shsft drives a, spur-wheel H carrying a crank pin H connected to the lower end of a rod H the upper end of which is connected to a lever J on a. transverse shaft J carrying levers J J one on each side of the riddle and connected thereto by rods J", J. The engine acts through this gearing to impart an oscillating motion to face of the riddle toward and into the wagons on which they stand, this operation being facilitated owing to the surface of the riddle sloping from the middle downward toward the ends, and owing tothe oscillation imparted to the riddle. In some cases owing to the sloped surface of the riddle the oscillation imparted to it is sufiicient to cause the material which does not pass through the riddle to be speedily shot off into the adjacent wagons without raking.
When a wagon has been filled with the ore which has passed through the riddle, the
two adjacent wagons will be filled more or less with the ore in larger pieces, and the:
train of wagons is then moved to bring the next three wagons into position so that the center one is beneath the riddle. Further, when one hold of a ship has been discharged, the gauntree may be moved so-as to bring it into position where the crane lifting the? tubs out of the next hold can emplty these ereinbe-;
. tend longitudinall over more than a single wagon, substantia ly as described. 1. Improved riddling machine compris tubs onto the gauntree grating as fore described.
. What I claim is:-
ing a gauntree beneath which wagons can pass, a riddle suspended transversely byi links to the gauntree, the latter being: shaped to admit a tram of wagons longitudinally of the riddle, the riddle being of a len th and breadth such that while it exten s entirely over one wagon its-ends ex-.
tend more or less over the wagons at each end of the one covered by the riddle, and; means to-impart an oscillating motion to the: riddle.
2. Improved riddling machine comprising;
a gauntree beneath which wagons can pass,
a riddle consisting of removably secured apertured plates so carried that the sun face of the riddle slopes from the middledownward toward the ends, the riddle being of a length and breadth such that while it extends longitudinally entirely over one wagon its ends extend more or less over the wagons at each end of the one covered by;
the riddle, links suspending the riddle transversely from the ganntree, and means: to impart an oscillating motion to the riddle.
3. Improved riddling machine compris-= ing a gauntree beneath which wagons .canI
wagon its ends extend more or cured apertured lates socarried that the surface of the rid e slopes from the middle downward toward the ends, the riddle being of a-length and breadth such that while it extends longitudinally entirely over one a riddle consisting of removably ses over the.
wagons at each end of the one covered by the riddle, links suspending the riddle transversely from the gauntree, means to impart an oscillating motion to the riddle and a horizontal grating secured on the gauntree above the riddle.
4. Improved riddling machine comprising a traveling gauntree beneath which wagons can pass, a riddle'transversely suspended by links hinged to the traveling gauntree, the riddle being of a length and breadth such that while it extends ongitudinally-entirel over one wagonits ends extend more or less over thewagons at each end of the one covered by the riddle, a motor carried by the traveling gaunt-reeand gearing enabling the motor to impartan oscillating motion to the riddle.
5. A self-contained, traveling gauntree and riddle for use on quays and the like, comprising side frames supported on traction wheels, cross frame members above the height of the'wagons to be served and spacing said sideframes apart sufliciently to transversely straddle a single w on, a riddle movably sus ended from sai gaunt-rec lon itudinally o the wagons tobe served, said riddle being of a length suflioient to ex- 6.
