UNITED STATES PATENT OFFICE.
ANDREIV BAROLAY, OF KILMARNOOK, NORTH BRITAIN.
Specification forming part ol' Letters Patent No. 106,452., dated August 16, 1870.
To all whom it may concern:
Be it known that I, ANDREW BARGLAY, of Kilmarnock, North Britain, have invented an Improvement in Ejectors and Oondensers and I do hereby declare the following to be a full, clear, and exact description of the same.
This invention relates to certain apparatus for eifecting a speedy and economical condensation ofthe exhaust-steam escaping from4 the cylinders of stealnengines, by the employment of which the construction of such engines is much si mplited. The apparatus is attached to .the exhaust pipe or pipes of the engine, and consists of certain passages, chambers, and valves, operatingtogether as fully described hereafter, so that water is discharged intermittently into the exhaust-steam, which is thus condensed, and is then, with the condensing-water, forced into a suitable cistern or cisterns.
Description ofthe Drawing.
Figure 1 is a sectional elevation of my improved condenser; Fig. 2, a` detached View of part of the apparatus drawn to an enlarged scale 5 and Figs. 3 and 4, modifications.
Gen era Z Description In Fig. l, the branch A is that to which the exhaust pipe or pipes of the engine is or are connected.
The steam, on enterin g the instrument, passes partly into the branch B and blows open the valve O, while that part of the steam which does not pass out through the Valve O escapes down the chamber D and blows out the water contained in the lower part thereof, through the valve E, into the surrounding cistern F.
At the upper part of the instrument the branch Gis situated. It is connected to a cistern of water, which flows in and iills the chamber H, in the bottom of which the valve or cock I, attached to the rod or spindle K, is itted to a correspondingly-formed Valve-seat. The spindle K is connected by rods to a cam or eccentric driven by the engine, so that the valve I is intermittently lifted and then al lowed to fall and close'on its seat.
The chamber L is that in which the feedwater is heated. Its upper part, above the perforated plate M, is connected to a water- `cistern by a pipe coupled to the branch N. The water falls into the cistern Ii through the perforations in the plate M.
The action of this form of blow-th rough con-.m
denser is as follows: That part of the exhauststeam which opens the Valve O is instant-ly condensed on coming into contact with the water contained in the chamber L. The water is thereby heated, and intended to be employed as feed-water for supplying the boiler or boilers, or for any other purpose.
The heated water escapes by the passage O, through the valve I, into the cistern Q, and it may be either pumped or drawn o through the branch It, or allowed to overiiow through the branch S.
Directly that the part of the steam which passes into the lower part of the condenser comes into contact with the water therein it blows it out through the valve E, and at the same instant the Valve I is lifted, which allows cold water to fall through the lower part of the condenser, which instantly condenses any Vapor that may remain therein. At the same time it fills the lower part of the condenser, so as to be acted upon and blown out by the steam at the next exhaust. As the engine is in action the operations now specified are continuously repeated.
Fig. 2 is an enlarged section of the lower part or valve-box of the blow-through condenser, given here for the purpose of showing its construction more clearly than that. is indicated at Fig. l.
The valve-box A is, by preference, square in plan, with a rectangular opening, A, at either side, closed by a flap-valve, O.
The lower part ofthe Valve-box is of pyramidal form, with the sides of the pyramid slightly curved, as shown at D, and the hollow underneath is iilled in with Portland cement or other material.
The valves O are tted with stops, so that they may not open more than a certain fixed distance.
The stops may be applied in various forms, two of which are shown at Fig. 2, at E and F, respectively.
r1`he Valve O is, by preicrence,lined with india-rubber, as shown at c and b, Fig. 2, it being held rm and close to the valve C by an interior plate, G, held by rivets H. y
It is preferred to construct the chief part of the instrument with air-spaces, or in any other way, to reduce their tendency for conducting heat. To this end an air-space is shown at Fig. l by the dark shading at the sides of the chamber H.
Fig. 3 is a vertical section, showing another modication of the condensing apparatus as it may be applied to condense the exhauststeam of steam-engines. In this case, instead of passing the steam into an annular space round the water-passage, the water may be passed into the annular space and the steam through the central passage.
A is a condenser, which communicates with the exhaust-port of the engine by the exhaust pipe B, to the bottom end of which a nozzle, C, is fitted, through which the exhaust-steam passes to the condenser A.
The water 'or condensing liquid passes into the condenser by the annular space D, its admission being regulated by the valve E, which is yopened and closed by the rods F, operated by a wiper-shaft, J, provided with a crank, K,
Ywhich may be actuated by any of the methods usually employed to operate the valves of steam-engines. The condensing-water is contained in a tank communicating with the annularchest H, into which it flows by the pipe G.
lhe condenser is supplied with a blowthrough valve, I, opening into the chest V, which is provided with an overiiow-pipe, U, through which the water used in condensing the steam may be drawn 0E and used for any1 purpose or allowed to run to waste.
With this, as in the preceding modification, an auxiliary condensing apparatus may also be applied, from which the feed-water required for supplying the boiler or boilers may be taken.
The working of this arrangement of the condensing apparatus is as follows: When the exhaust-valve of the engine is opened the exhaust-steam escapes down the pipe B, and through the nozzle C into the condenser A, where it comes in contact with the Water in the condenser, and forces it through the valve I into the chest V, part of the steam being condensed in consequence, and the remainder is condensed by the injection-water admitted through the annular space D during each lift ofthe valve E.
Fig. 4 is a vertical section, showing another modification ofthe apparatus.
A is a condenser; B, the pipe leading from the exhaust-port of the engine-cylinder. C is the cistern, which contains the water which escapes into the pipe D during each lift of the valve E; thence it passes through the perforated pipe or rose F into the condenser A.
The valve E is operated by an eccentric, a, actuating a crank, b, on the axis of which two tappets, c and d, are keyed, which lift the lever e Aby acting upon the pawls fand g. As soon as the tappet c has passed the point of the pawl f the lever e drops and closes the valve E, and on the return stroke the tappet d lifts the pawl g, and opens the valve at the same time the tappet c passes under the pawl f, which is centered on the axis h, and is ready for another lift.
The action of this modification is similar to the preceding, and therefore need not be further referred to.
Claims.
1. A chamber closed at the lower end by a water-trap, in combination with a vdischarge pipe or nozzle, Valve I, and a surrounding annular steam passage, when the condensing water is discharged intermittently by theoperation of said valve, substantially as described.
2. A narrow pipe or passage communicat ing with the exhaust-ports of an engine, and with a water-reservoir, and provided with a valve operating so as to discharge water intermittently into said passage, when the latter is contracted below the point where the water is discharged into it, as described.
3. The combination, with the said chamber, of a water-reservoir and a valve closing the communication between the two, and operated substantially as described.
4. rIhe cistern L and valve C, combined with the receiving-chamber, and with the cistern F, as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ANDREV BARCLAY.
