HYDRAULIC TRANSPORTATIQN SYSTEIE.

Speccation of Letters Patent. Patented June, 13, 1922.

Application led August 19, 1921. Serial No. 493,648.

lhio, have ini-.vented certain new and usefulv improvements in Hydraulic Transportation ystems. oil which the following' is a specification.

This invention relates to hydraulic sluieinp: and transporting systems tor ashes, mamitacturing refusa clay7 sand, gravel, rock, ore and other solid substances, and its primary ohiect is to provide a simple, practical and h ifrhly eiiicient method ot givingauni Yform transporting capacity to every part of a sluiccway or other conduit` irrespective of differences in their grades,q cross-sectional dimensions or roughness.

l attain this object by continuously circulating through a part oit a sluiceway or other conduit ot lesser transporting capacity than a. preceding or following part` a quantity of water which with the normal iow through the other parts is suilicient to carry the material. through said part at a rate'equal to that ot the tull capacity of any other part.

My invention is particularly adapted for use in hydraulic transportation systems wherein the transporting capacity of any part is limited by natural topographical conditions, cost ot material. or other circumstances. and it provides an economical method ot remedying a condition which ordinarily would necessitate a reduction in the y rate oi tee-d below the capacity oi the pump or other contrivance provided to convey material to a point o' delivery.

Tn the accompanying drawings in the various views ot which like parts are similarly designated g Figure l represents a sectional elevation ot a hydraulic. conveying system to which my invention is applied;

Figure 2. a similar elevation showing a diii'erent arrangementy ot the parts ot the system` and Figure 3 a plan view o'F a sluiceway showing still another condition which would render the use oi my invention desirable.

Figure l oi the drawings shows a hydraulic sluicing or transporting s vstem tor ashes. manutacturing refuse, clay. sand, ,Qraveh rock.y ore and other solid substances, including` a sluiceway 5. which is inclined from an elevated point ot supply A to a sump or reservoir 6. from. where the material is conveyed to a point of delivery through the instrumentality of a pump 7,

To illustrate the use and advantages ot my invention I have shown the sluiceway to he composed ot two parts one ot which, from C to D, has lesser hydraulic gradient or slope than the preceding part from to C, and a lesser transporting capacity than either the part A to C or the part D to 0.

.lt is obvious that the transporting capacity oit the entire system is limited to that ot the part C-D, and to remedy this limitation, a supplementary quantity ot water is supplied at the upper end of sai d part suliicient to compensate for the difference in its inclination with relation to the preceding aart or its transporting capacity with rela1 tion to the parts between which it is disposed.

The water supplied at the upper end of the part C-D ot the sluiceway is drawn off at the opposite end of the same, after it has performed its Vfunction of increasing the transporting capacity of said part7 and under conditions where a scarcity of water necessitates an economical ruse thereof, some or all et this water maybe returnedby means of a pump 9 tothe upper end of the part C-D ot the sluiceway to repeatedly perterm its function in a continuous circulatory movement.

In the illustration shown in the drawings, the water is supplied to the upper end of the part C-D from a reservoir 8 through the medium oi the pump 9 and. a conduit l2 and is withdrawn at the lower end of the part through anv overliow l0 trom where it is conveyed to the pump 9 by a pipe 13.

In Figure 2 ot the drawings I have shown the sluiceway as having apart E-F ot closed conduit following a part Fv-G of lesser transporting capacity. The method of applying my invention is similar to that herein described with relation to the construction shown in Figure l.

Figure 3 illustrates a sluiceway in which a part lll-K has a lesser transporting capacity than the preceding part K-Ti by reason oi a diiierence in their cross-sectional torni.

The application ot my invention to a sluiceway of' this character is similar to the method illustrated in Figures l and 2 and needs no further illustration or explanation.

Having thus shown and described the apppcatjon of my improvements by the simplest and most :feasible methods at present known to me, I desire it understood that variations in the arrangement of the parts may be resorted to Without departing trom the spirit of my invention.

It has been indicated hereinbetore that in places Where a plentiful supply of Wateris available, the pump t'or returning of Water ttor reuse through the retardingg` section oi the sluieeway mayv he eliminated, and it will he apparent that my improvements are applica-ble to closed conduits as Well as to open sluieeivays. and under conditions ditileront from, those shown `in the drawings and hereinbeifore describedy which. necessitate an acceleration of the flow oit material through any part oit a hydraulic system for the conveyance of solid substances separat-e from the other parts thereof.

Having thus described my invention, what I claim and desire to secure by Letters- Patent is:

l. In a hydraulic transportation system having in a sluiceway or Conduit, a part ot lesser transporting capacity than another part thereof, means ttor continuously circulating a supplementary quantity of Water through the part first mentioned for `the purpose of inrreasing' its transporting capacity, exclusive of said other part.

2. In a hydraulic transportation system l having in a sluiceivay or conduit, a part of lesser inclination than another part thereoh means for continuously circulating a supplementary quantity of'water through the part first-mentioned for the purpose of increasingr its transporting capacity,y exclusive of said other part.

3, In a hydraulirv transportation system having in a sluieeway or conduit, a part oi lesser transporting` capacity than another part thereof7 means for supplying supplenientary Water at one end of the part first mentioned for the purpose of increasing its transporting Capacity and Withdrawing` 'this Water at the other end ot the same.

lll. In a hydraulic transportation system having in a sluiee-Way or Conduit, a part oi lesser transporting capacity than an other v)art thereof, a source ot Water supply, a pump for Conveyinpr 'Water `from said sourre to an end of the part first mentioned7 and an overflow Weir for returning said Water to said source 'from the other end of the saine.

5. The method ot equalizing the transporting capacity of a sluiceyvay or conduit having' apart otlesser transporting capacity than another part` Consisting in continuously circulating' a supplementary quantity of Water through the part first mentioned, eX- elusive of said other part.

6. The method ot equalizing the transporting capacity ojl' a sluieeway or` conduit having a part ot lesser transporting capacity than another part, consisting` oit supplying supplementary Water at an end of the part first mentioned and withdrawing it at the opposite end of the same. V

-In testimony whereof I have a'liixed my signature.
