SPECIFICATION forming part of Letters Patent No. 581,520, dated April 27, 1897.
Application filed .Tune 25, 1894. Renewed December 15, 1896. Serial No. 615,806. [No model.)
To all whom t may concern.:
Beit known that 1, HORACE SEE, of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Ash-Ejectors for Steam Vessels, which invention is fully set forth and illustrated in the following'speciiication and accompanying drawings.
The object of this invention is to provide an efficient hydropneumatic ash ejector which may be automatically started into operation at the desired time.
The invention will first be described in detail, and then set forth in the claims.
Figure 1 of the accompanying drawings shows in sectional side elevation a hydropneumatic ash-ejector embodying my invention. Fig. 2 is a sectional side elevation illustrating a detail of construction hereinafter described. f
In said drawings the several parts are respectively indicated by reference-numbers as follows:
1 indicates an ashes receptacle or hopper which may be provided with any suitable cover. The lower part of said hopper is connected to a pipe 2, which in turn is connected to a discharge-pipe 3, leading overboard from the vessel at anysuitable point. To the lower part of the discharge-pipe 3 is connected an ejector-nozzle 4, connected to an ejector-pipe leading from any suitable force-pump. The point of the ejector-nozzle 4 where it enters the discharge-pipe 3 is provided with a valveseat 5, upon which is seated a conical valve 6. Said valve forms an extension of a stem 7, which is connected to a piston 8 9, of differential diameter, located within a cylinder or chamber 10, the portion 8 of said piston being of greater area than the portion 9. The valve-stem 7 is provided near its lower end with an enlargement 11, forming a plunger within a recess 12 in the top of the chamber 10, thus constituting a reverse dash-pot arrangement. Said valve-stem is provided with hydraulic packing 13, and the differential piston 8 9 is also provided with hydraulic packing 14: 15. The packing 14 is secured by a screw-collar 16 and the packing 15 by a screw-bolt 17 and washer 18.
To the bottom of the differential piston 8 9 is connected, by means of the screw-bolt, if desired, one end of a coiled spring 19, the other end of which may be secured to the bottom v of the cylinder or chamber 10. Said spring is only made strong enough to overcome the weight of the valve-stem 7 and piston 8 9 and keep the valve 6 against its seat when there is no pressure in the pipe or nozzle f1.
A pipe 20 connects the ejector-nozzle 4. with the cylinder 10 below the differential piston, and a pipe 21 connects the two ends of said cylinder above and below said piston. The pipe 21 is provided with a valve 22, held closed by a spring 28 until the desired working pressure of water has been obtained in the pipes, when said spring will yield and allow water to pass through the valve 22 into the upper end of the chamber 10, above the piston 8, as hereinafter more fully described. Between the valve 22 and the upper end of the chamber 10 a three-Way cock 24. is provided in the pipe 21. Said cock is provided with a lever or handle 25 for operating the same and is so constructed that its plug can be turned so as to admit Water into the chamber 10 orto drain into the atmosphere through the nozzle 26. The chamber 10 is provided with a drain-pipe 27 for carrying off any water which may leak past the piston 8 9.
Located in the pipe 2, which connects the hopper with the discharge-pipe 3, is an airvalve 28, which may be a spring check-valve or a valve of any suitable construction. The air-valve 2S (shown in section detached in Fig. 2) has a stem 29, provided with a coiled spring 30 within a cap 31, thus constituting a spring check-valve.
Heretofore in hydropneumatic ash-ejectors an air-valve has been placed on the dischargepipe 3 above the branch 2, but in practice 1 have found that such location of said valve is not a favorable one, as when the lid of the hopper is closed the ejector does not start in operation because of the vacuum created in the pipe 2. This difficulty l have overcome by locating the air-valve 28' in the position shown in the drawings and admitting air through said valve to the pipe 2, thus destroying the objectionable vacuum in said pipe. The cover of the hopper may thus be kept closed, as is often desirable, when the ejector IOO is not at work in order to prevent water or other objectionable matter entering the ship through the hopper, which might happen if the lid of the hopper were open when the ejector was not in use.
The operation of the apparatus is as follows: Then it is desired to elevate the ashes and discharge the same overboard, the cover of the hopper l may, if desired, be first closed, and the handle 25 of the cock 2a is then moved into the position shown in the drawings, and the force-pump connected to the ejector-nozw zle Ll is started and water forced into said nozzle. Said water flows through the pipe 2O into the lower part of the chamber l0 and from said chamber into the pipe 2l. lVhen the pressure of said water is suflicient to compress the spring 23, the valve 22 will open and allow the water to pass through the pipe 2l and cock nl-i into the chamber l0 above the differential piston 8 O. The area of the upper portion S of said piston being greater than the area of the lower portion 9, said piston will be forced downward andthe conical valve G thus released from its seat. The arca oi' the valve and weight oi' the valve-stem 7 will assist in this downward movement of the piston S 9, and the spring 19 and compression of water below the piston 0 will prevent a too-sudden arrest of the same. Then the valve G has been thus opened, a solid jet of waterenters the discharge-pipe 3 through the tapered bore of the nozzle 4 under a very high pressure and with great velocity. The cover of the hopper l, if closed, is then opened and the ashes thrown into said hopper, from which they pass into the discharge-pipe 3, where they encounter the jet of water entering through the ejector-nozzle t and are carried with the water up through said pipe and discharged overboard, this discharge continuing as long as ashes are thrown into the hopper l.
Then the work has been completed and it is desired to close the valve G, the lever 25 of the cock 2l is moved into the position shown by dotted line 29. Communication is thus shut off between the ejector-nozzle 4c and the upper end of the chamber l0 and communication established between said ejector-nozzle and the atmosphere through the nozzle 2G. The pressure of water in the chamber l0 will then be sufficient to elevate the piston S 9 and close the valve 6. The conical or pointed end of said valve in this upward movement will force out any foreign matter which may have lodged in the ejector-nozzle '-1. The plunger 1l and dash-pot l2 will prevent the too-sudden seating of the valve G.
The construction above described presents the advantage ot automatically and quickly opening the ejecting-valve of an ash-ejector by simple mechanism, an advantage which is of considerable importance, as it has been found that in an ash-ejecting apparatus in order to start the machine into operation with certainty it is necessary that said valve should l.
