PORATION OF NEW DRAIN FOR RECEPTACLES R HOPPERS.

Application filed March 17, 1923. Serial No. 625,692.

To all whom it may concern:

Be it known that 1, CHARLES WILSON Ross, a citizen of the United States, and a resident of thecity of Philadelphia, in the county of Philadelphia and State of Penn'- sylvania, have invented a new and useful Drain for Receptacles or Hoppers, of which the following is a specification.

This invention relates to drains for receptacles or hoppers and more particularly to drain attachments for the gates of ash hoppers.

In boiler houses or similar plants where large quantities of furnace ashes are handied it is customary to quench the ashes with water after they have been deposited in the ash receptacle or hopper. The quenching water settles in the lower portion of the mass of ashes and either leaks out around the closed discharge gate to the floor of the ash pit or tunnel, or is discharged with the ashes when the gate is opened. This causes an untidy condition around the discharge gates and may render the floor beneath the hoppers slippery and dangerous. Moreover, where bottom discharge hoppers, and certain other types of hoppers are used, the hot quenching water leaking from the hoppers or passmg out with the ashes in liable to scald the workman attending to the hoppers.

For these reasons, it is desirable to have some means for effectively draining oil the quenching water from the ashes while the discharge gate is closed, which will not interfere with the proper discharge of the ashes upon the opening of the gate.

An important object of the present invention is to provide such means for receiving the drainage from ashes or similar material contained in hoppers, bins or other receptacles and to so construct and arrange the drainage receptacle that it will be compact and will not interfere with the normal operation of the discharge gate or closure of the receptacle norv withthe dischar e of the ashes from the receptacle. Whi e the invention is especially designed for use upon ash hoppers with side discharge gates, it may be applied to ash hoppers of the bottom discharge type, and is aplicable to hoppers or receptacles used in the handling of other materials similar to ashes, such as sand, gravel or the like.

The objects and advantages of the invention will appear in the following specification, reference being had to the accompanying drawingin which,

Figure 1 is a perspective view of an ash Figure 2 is a side elevational view, partly in cross section, showing the position of the drain attachment when the ash gate is closed,

Figure 3 is a side elevational view, showing the position of the drain attachment with the ash gate open, and,

Figure 4 is a front elevational view, partly in cross section, of the drain attachment showing the arrangement of the discharge spout thereon.

In the drawings, wherein similar reference numerals indicate like parts throughout the views, 5 indicates any usual ash hopper or receptacle such as may be used in boiler plants, usually below the boiler furnaces. The hopper shown is provided with a gate 6 pivoted on trunnions 7 extending outwardly from the sides of the mouth 8 of the hopper. The gate 6 has a curved valve or closure pprtion 9, as shown, which normally closes the mouth 8 of the hopper. Forwardly extending arms 10 at either end of the gate 6, carry counterweights 11 at their outer ends. A downwardly inclined lip or ledge 12 is fitted to the hopper 5 below the mouth 8 and gate 6 and is held in place by upstanding side members. This structure represents a wellknown type of ash gate and isused merely for illustrative purposes in connection with my drain attachment, which may be applied to other types of hoppers, whether provided with pivoted or sliding gates.

The drain attachment includes a trough 13 located below and preferably extending across the width of the lip or ledge 12. This trough may be pivotally connected to the lip 12 by bolts passing through upstanding lugs 14 formed on the trough 13 and lugs15 on the underside of the lip 12, but other suitable or convenient forms; of pivotal connecting means may be used As shown in Figure 2 of the drawings, the. trough 13 is normally directly below the edge-oi the lip 12, so as to receive the water leaking. out around the 11 either by hand or b meager gate and draining down the lip 12 from the mouth 8 of the ho per, when gate 6 is closed. The bottom 16 o the trough 13 slopes genorallyv downwardly toward one end 17, at or near which point a spout 18 is formed.

Suitable means are provided for attachment of the trough to the discharge gate or its operating mechanism. By way of example, lugs 19 may be cast on the lower portion of the trough 13 at either end thereof. Links 20 or equivalent devices are pivotally connected to the outer ends of these bearings by bolts or the like. The outer ends of the links 20 are also pivotally connected to the counterweights 11' as shown at 21. The position and arrangement of the pivotal connection between the trough 13 and the lip 12 and of the pivotal connection between the trough and the counterweights are such that when the counterweights 11 are swung downwardly to move the valve or closure 9 of gate 6'away from mouth -8, the trough 13 will be swung back beneath and away from the lip 12, as shown in Figure 3 of the drawing. It is obvious that the specific form and arrangement of pivotal connections are merely illustrative as other constructions capable of producing substantially the same relative arrangement and movement of the parts may be substituted therefor. For carrying oil the water from trough 13. a drain pipe 27 is provided, into which the water may flow from the spout 18. An enlarged head 23, having its front wall cut away as at 24, may be fitted on the upper end of the pipe 22, if so desired.

When the gate 6 of the ash hopper 5 isclosed the position of the arms 10 carrying the counterweights. 11 causes the trough 13 to be held up below the outer or lower edge of the lip 12, so that when the ashes in the hopper are quenched'and the water seeps down and leaks out of the mouth 8, around the gate 6,, it will drip into the trough 13 and flow from thes out 18 into the drain pipe 22. The quenc ing water being thus carried away, the ashes'will be in a practically dry state and no water will flow out of the mouth when the gate is opened by the workman emptying. the ho per. While the discharge gate is preferab y so constructed and fitted as to permit water toleak out around it, it is usually suficiently tight to prevent ashes from leaking out when the gate is closed. However, should some ashes pass out with the water and be deposited in the drain trough, they will not clog the drain device, but will be dum into the ash car when the gate 6 is open to remove the ashes from he hopper.

' When it is desired to open the gate 6 to empty the ashes, a downward movement is imparted to the arms 10 or counterweights power means.

Through the action of a links 20 this movement will swing the trough 13 about its pivotal connection between lugs 14 and 15, so that the trough will be entirely out of the path of movement of the ashes, which will slide oil of the lip 12 clear of the trough.

-Upon the closing of the gate 6 the trough 13 will be restored to its operative position indicated in Fig. 2 and will catch any Water that may leak from the hopper between mouth 8 and its gate 6.
