ASH-EJECTOR.

SPECIFICATION forming part of Letters Patent No. 716,418, dated December 23, 1902.

Application filed May 13, 1902 Serial No. 107,110. (No model.)

To all whom t may concern:

Be it known that I, LUGWIG IfIooHs'rnIN, a subject of the Emperor of Germany, whose post-office address is Katherinenstrasse 14, Dietrichsdorf, near Kiel, Germany, have invented certain new and useful Improvements in or Connected with Ash-Ejectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In connection with ash-ejectors as hitherto employed for discharging ashes from ships and the like it has been found that inconveniences arise in tending them, as jolting and shaking occur in the pressure-pipe when the ash-ejector is started, and in consequence of the slight pressure at starting the ash-ejector fails to act when the nozzle-pipe is opened. Moreover,several persons are always required to look after the ejector.

By means of the apparatus that forms the object of the present invention the working is simplified and the above-named difficulties are obviated. The apparatus enables the pump to work continuously independently of the ash-ejector being in action or not. The pump-piping is divided into two parts by the introduction therein of suitable reversing-organs, so that the one pipe leads to the ashejector, the other to the outside or some other suitable place. This reversing action may be effected either by the direct or indirect movement of the reversing-organs. Contrivances for indirect reversing are illustrated in Figures 1 to 6 and for direct reversing in Figs. 7 to l0. Compared with those for indirect reversing the direct reversing contrivances have the disadvantage of involving a large expenditure of power. This kind of apparatus is suitably composed of avalve-cone body furnished with double Valve-cones, one of which cones closes the nozzle-pipe leading to the ashejector, the other closing asecond nozzle-pipe, leading to the outside. The reversing of these Valve-cones can be effected by the actual valve-body being formed as a differential piston or as a single piston, the water under from one another, in which case the one organ is applied to the ash-ejector, the other to the pump or at some other spot. The principal effect of such a device is that after the ejector-nozzle pipe has been opened the pressure of Water necessary for the working can at once enter; further, that after the pressurepump has been started all further attention is rendered unnecessary and stoppage or overrunning of the pump and consequent jolting and shaking in the pressure-pipe itself avoided.

In the accompanying drawings, Figs. Ito G represent indirect-switching devices, Figs. 1 and 2 the construction of the valve-cone body as a differential piston, Fig. l showing the smaller piston shut off from the dischargingchamber and receiving the water under pressure through special openings,whereas in Fig. 2 the said piston is shown as being directly in the discharging-chamber. Fig. 3 illustrates the employment of an ordinary piston, the water under pressure being conveyed to each side of the piston by special conduits. Figs. 4l, 5, and 6, which relate to Figs. I, 2, and 3, represent different positions of the distribution-cock. Fig. 7 shows the employment of two valves, Figs. S to l0 the employment of a three-way cock.

The arrangement of the reversing-organs is as follows: The nozzle-pipe b, Fig. I, leads to'the ash-ejector, the nozzle-pipe c to the discharge-pipe. Both are closed by the cones 7c and z', connected with the differential piston s r. The valve-cone body is hollow, and its interior communicates, by holes d andf,with the supply-pipe e or chamber Z. The dierential piston, Fig. I, consists of the larger piston s and the smaller piston r, to the latter of which the water under pressure is conveyed through openings g. For reversing purposes the cock a is employed. If the cock be turned into the position indicated in Fig. l, the water flows from the chamber e through the passage 1o and the cock a over the larger piston s of the differential piston, and in consequence of the considerable difference of surface between the surface of the larger piston and that of the smaller piston causes the differential piston s r to descend, the cone c being removed from the nozzle-pipe b--that is to say, opens the pipe and closes the nozzle-pipe IOO c. The consequence is that the stream of water from e flows to the ash-ejector and the work of the ejector begins. If the cock d now be turned to the extent of ninety degrees, Fig. 4l, the surface of the piston s will be brought into communication with the external atmosphere-that is, will be relieved of pressure while the smaller ypiston r, which is held continuously under water-pressure by the Water reaching it through openings CZ g, must now move in opposition to the differential piston, so that the nozzle-pipe b is closed. The water under pressure will now pass through df Z and the nozzle-pipe c to the discharge-pipe as long as the cock d is closed, whence it is clear that the pressure-pump remains continuously in action quite independently of the ash-ejector-that is, it requires no special attention.

The arrangement illustrated in Fig. 2 differs from that shown in Fig. l only by the circumstance that the smaller differential piston r projects directly into the discharge-chamber Z. The action is the same as in Fig. 1. The second position of the cock a is shown in Fig. 5.

In the arrangement with a single piston (shown in Fig. 3) the Water under pressure is conveyed to the dierent surfaces of the piston only through the openings cZf, and in this case the cock d is furnished with two ways, one of which eects a communication of the pressure-chamber Z with the one side of the piston and the other a communication of the opposite side of the piston with the atmosphere. The cock @,as shown in Fig. 3, is in the position in which the top of the piston is in communication with the atmosphere, the bottom with the pressure-chamber Z. The action will at once be seen from the drawing. The upper and lower surfaces of the piston .are alike.

According to Fig. 7, two valves QJ are inserted in the pressure-pipe of the pump,which must be simultaneously operated, so that the one is opened, Whereas the other is closed. Quick-closing valves are desirable, but instead of these cocks may be put in. In this case also the pipes to the ash-ejector and to the outside are alternately opened or closed.

In Fig. 8 the pressure-pipe of the pump is provided with an ordinary three-Way cock w, and when the plug is in the position shown in Fig. 9 the water is conveyed to the ashejector, While when the plug is in the position shown in Fig. 10 it is conveyed to the outside.

In the single-piston arrangement shown in Fig. 3 the Water under pressure is conveyed partly through h and partly to the different piston-surfaces only through the openings df, and in this case the cock d is furnished with tWo Ways, of which the one, t, forms the communication of the pressure-chamber Z With the one side of the piston, the other,p, the cornmunication of the opposite side of the piston with the atmosphere. In Fig. 3 the cock d is in the position in which the top of the piston is in communication with the atmosphere, the bottom with the pressure-chamber Z. In Fig. 6 the position of the'cock d is reversed. It is obvious that the water under pressure flowing through d f collects in the chamber Z, flows partly away through Zz, and partially exerts pressure on the lower or upper surface of the piston o, according to the position of the cock a. The piston-surfaces are alike above and below.

The chief feature of the invention consists in the avoidance of the joltings and shakings which formerly occurred and in the ability to work the whole apparatus with only a single attendant.
