EJ'ECTOR.

T 0 all whom it may concern 7 v Be it known that I, EUGENE HAHN, a citi- 'zen of Hungary (having declared my intention of becoming a citizen of the United- States), and Pennsylvania, provementsin Ejectors,

a resident V of Philadelphia,

This invention relates to ej'ectors for ashes andsimllar materi'al, and more particularly to that type of ejector inwhich the material is sucked into an ejector pipe and forced therethrough by means of the rapid discharge of a fluid, such as steam or compressed air, through a nozzle suitably 10 Although ejectois of cated in the said-pipe; this general type are well known in the art, their application to boats, and particularly to ocean going vessels, is complicated by certain unique factors presentingproblems which must be solved'before theejectors can be 1nade'suitable for'this style of ,work. It

' is the" adaptation of these e ectors tense in vessels, particularly vessels employed in ocean trafiic, which constitutes the object of my invention.-

j The bar 26,

valve spindle, 20, extends outwardly from the valve in a direction substantially parallel to the rod, 14, and twoarms, 21 and 22, secured to the body of the valve, extend therefrom one on each side of the spindle and in the same substantially horizontal The arm 22 is rigid, and a slot 22 is formed therein, as shown in Fig. 1, while the arm 21, is pivoted at its inner end to the valve body. A rod, 23, is pivoted at one end to the outer extremity of the arm 21, and

also to the valve spindle, 20, and passes through the slot 22*, in the arm 22. The outer extremity of the rod, 23, is forked, and vertical slots, 24, are formed in the two forks. The operating rod, 14, passes be- ,tween theforks of the rod, 23, and pins, 25,, carried by the operating rod extend into the slots, 24, and so form a sliding connection between the said operating rod, 14, and the rod 23. By means of this connection between the operating rod and the spindle of the valve, the openings and closings of the cap,10, and of the valve are made to syn chronize, and neither one can be opened or closed independently of the other. The rod,

"23,-is extended beyond the rod 14, and a bar,

26, secured at one end to the floor by means of a swivel attachment, 27, is adapted to be swung upandretained in vertical liSltlOIl, in which position it stands in'the pat of the said extension upon the rod 23; and thus, when the valve and cap are open and the rod 23 is in the position shown in dotted lines in Fig. 2, the bar, 26, being swung up acts as an additional and positive lock for the apparatus to retain the valve'and cap in the open position until such time as it is desired to close them. A spring, 23 secured to both the bracket, 16, and to the rod 23, tends to close and keep closed the cap and valve. performs-a further function of extending across the cover, 6, in which position it may be locked by means of a suitable clamp 28 upon the floor which engages the free acting'to fastendown the cover, 6, if this is necessary. The means for retaining the bar, 26, in vertical position comprises in the present instance an upstanding bracket 29.

into which the saidbar passes and to, which through which the rod, 12, and the pipe, pass respectively,

whereby the j oints'are rendered watertight.

Anozzle, 34, connected with a A further fundamental extremity of the bar, the bar-thus water line, extends into the interior of the pipe at a point nearv the outer endthereof and discharges directly through theopen end of the pipe, ridding the surrounding area of the dust given off by the ashes.

In Fig. 6 I have illustrated a modification in which a closure, 10', is mounted within the pipe and swings up into a cavity formed in the pipe for its reception. The pivot bar, 1O upon which the closure is mounted, extends through the side of the pipe, and has a lever arm 10 to the outer end of which the rod, 12, is pivotally attached. I

As the operating element of my ejectorI prefer to employ compressed air. Upon ocean golng vessels it is a precept to conserve the supply of sweet water as much aspossi reason condensers are em' most objectionable features attached to the use of these ejectors in ocean going Vessels.

objection to ejectors of this type in vessels employed in of the entire operatlon, as well as ellmmatmg one'of the ocean travel, has been'thefact that in heavy seas there would be continual danger of water entering the interior of the vessel by way of the e ector pipe, and as a consequence of this possibility no underwriters could befound to subscribe to vessels supplied with this form of ejector. This objection I have completely overcome by providing means for positively sealing the end of the pipe against the entrance of water. i

The conservation of necessity on vessels it is to be expected that valve supplying fluidwill be shut ofl after ashes have been discharged, especially as the operation of the valve s accompanied by plainly audible noises. Thus by interconnect ing the operation of the valve and the cap at the end of ejector, so that the latter closes down when the valve is shut off, it is assured, that the cap will be shut tight after discharge of the ashes has been completed. In addition to these devices for preventing power being of prime the entrance of water into the e ector: pipe,

secondary means is provided for preventing positively the entrance of water into the vessel by way of the pipe, these means consist ing of the valve, 7 and the water tight cover, 6, with its clamping bar, 26.

These variousdevices though substantially foolproof areessentially simple, are easily installed, and are free from complicated parts and fixtures which might get. out of.
