Improvements in Steam Ash-ejectors.
I, JOHN FOSTER PANKHURST, of Number 202, Franklin Street, in the City of
Cleveland, County of Cuyahoga, and State of Ohio, United States of America,
Manufacturer, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My invention relates to means whereby steam power may be utilized to eject the
refuse ashes and clinkers from the stoke hold of a marine vessel, and its objects are
to provide a simple, forcible and effective device for accomplishing this purpose,
positive in its action, and not liable to become choked.
My invention consists in the combination and arrangement of the various parts
and construction of details as shown in the accompanying drawings described herein,
and more specifically pointed out in the claims.
In the accompanying drawings
Fig. 1 is a plan view of the front of boilers and ash ejector as they would be
arranged in the hold of a vessel;
Fig. 2 is a cross section of the vessel showing a side view of ejector and pipe to
the side with steam connections;
Fig. 3 shows a plan view of the ejector detached from its connections and
enlarged;
Fig. 4 is a vertical section of the ejector on centre line.
Heretofore ashes and other refuse have been hoisted from the hold in buckets or
by similar apparatus, creating considerable discomfort from noise and dirt, and
requiring considerable time and delay.
It is also known that a form of water ejector has been used for this purpose, but
difficulty has been found in insuring efficient delivery.
My invention wholly accomplishes this purpose and is constructed as follows;
A is a conically shaped hopper provided with the peculiarly formed grating A¹ at
its open upper end, supported upon the ring and brackets.
This hopper A receives the refuse ashes, the grating sifting out any portions
which might become entangled in the pipe. The grating A¹³ will be seen to
be constructed of cross-bars A' on edge and connecting bolts a¹ with sleeves a²;
this construction allows the ashes to pass through readily, the sleeves turning upon
the rods with little friction.
At the bottom of the conical receiver A. is attached the cast elbow B, tapered
bove to enclose the lower edge of the cone A, and having its outer opening pointing
pwards at the proper angle to discharge the ashes above the water line.
At the turn of the elbow beneath the mouth of the cone and where the heaviest
veight and thrust of the ashes are borne, is placed the orifice of a steam jet C, at
he same angle of elevation as the outwardly directed arm of the elbow, and in the
entre line of its opening. In the rear of this jet opening and communicating with
t, is placed the pipe connection D, communicating with the boiler or steam drum
[Price 6d 1

page_text: as shown in Figs. 1 and 2. A valve as D' is placed upon this pipe to control steam
admission or cut-off. The ejector or outlet pipe E leads directly toward the
side of the vessel as shown in elevation in Fig. 2, so that the discharge will take
place above deck. A valve sliding in vertical guides as F may be used to prevent
water from outside the vessel from entering the pipe.
In use, the conical receiver having been filled with refuse, the steam is admitted
through the opening, and rapidly forces out any material dropping into the
elbow, besides creating a suction which draws downwards anything remaining in
the cone.
The action of this form of ejector is prompt and certain, while inexpensive and
durable in construction.
It will be readily seen that two stands may be used with pipes piercing both sides
of a vessel, to be used alternately as the direction of the wind requires, or a double
form can be used with two pipes and a single stand.
I do not claim the exact shape or size of the various parts, in which slight
modifications may be made without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :--
1. A. vertically arranged conical ash-receiver, in combination with a separate jet-
receiver, the said jet-receiver being provided with a conical upper extension and
curved discharge-passage continuous with the conical opening, a reduced inlet in
the curved passage, and boss with threaded opening to the inlet, substantially as
described.
2. In a steam ash-ejector, a vertical conical ash-receiver A, provided with an
interior annular ring near its upper enlarged extremity, cross-bars A', traversing
the opening and resting upon the annular ring, separating rollers a¹ between the
cross-bars A', bolts a², passing through the cross-bars A' and rollers a¹ and con-
necting them together, with a curved jet-receiver B, conical at its upper extremity
to receive the lower end of the ash-receiver A, a smooth curved lower passage
connecting the vertical opening of the jet-receiver with a discharge-opening, and a
perforated boss C, with opening into the curved surface, substantially as described.
3. In a steam ash-ejector, upper and lower vertical cones A and B, the upper cones
being provided with transverse bars A and separating-rollers a¹ and snugly fitting
within the lower cone at its upper extremity, the lower cone being provided with a
smooth curved interior passage, and discharge-opening adapted to receive and
discharge the contents of the upper cone, substantially as described.
4. In a steam ash-ejector, the combination of an upper receiving-cone and lower
ejecting-cone having a discharge-opening, the said upper cone being provided with
transverse bars and rollers and detachable from the lower cone, substantially as
described.
5. In an ash-ejector, two inverted conical openings A and B, vertically arranged
one above the other, the lower cone terminating in a curved outwardly opening
passage and provided with a boss C and perforated inlet c, substantially as
described.
