CHARLES H. "WATEROUS, OF BRANTFORD, ONTARIO, CANADA.

PORTABLE ENGINE.

SPECIFICATION forming part of Letters Patent No. 358,952, dated March 8. 1887.

Application {'ed Jul',` 17, [886. Serial No. 208,247. (No model.)

T all whom it may concern:

Be it known that I, CHARLEs H. WATER- OUs, of Brantford, in the county of Brant, Province of Ontario, Canada, have invented certain new and useful Improvements in Portable Engines; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The main objects of my invention are, first, to utilize the wheels upon which the engine is mounted for condensers; second, to accelerate the condensation of steam in the condensers, and, third, to increase the draft of thefnrnace.

It consists, essentially, of a hollow watertight wheel into which the steam-cylinder is arrangedto exhaust, of an air pump or blower connected with the exhaust-pipe, and of certain other improvements, hereinafter described.

In the accompanying drawings like letters designate the same parts in the several figures.

Figurel is a plan View of a traction-engine to which my improvements are applied. Fig. 2 is a side elevation of the same. Fig. 8 is a side elevation of one of the condensing-wheels on an enlarged scale, a portion of which is broken away to disclose the internal parts thereof. Fig. Lis a transverse section of the same on the line x x, Fig. 3. Fig. 5 is a detail View on an enlarged scale of one of the exhaust-rings and portions of the hub of the condensing-wheel and axle adjacent thereto, and Fig. 6 is an elevation on an enlarged scale of the face of said exhaust-ring which bears against the hub of the condensing-wheel.

Although, for the purpose of illustration, I have shown my improvements in connection with a traction-engine, they are equally applicable to portable engines generally.

Referring to Figs. 1 and 2 of the drawings, A represents a vertical boiler 5 B, a two-cylinder compound vertical engine supported upon the tractiolrwheels C C, which turn on axles D D, secured to boiler A, and upon a forward steeringwheel, XV, which has bearings in a yoke secured in the usual way to the framework N N of the engine.

Q is the engineshaft, extending across the machine, upon which is secured the balancewheel Q', and a sprocket-wheel witli an internal friction. (Not shown.)

It is a parallel countershaft, upon the ends of which are secured sprocket-wheels R R', and at an intermediate point the compensating gear R2 and sprocket-wheel S, through which said counter-shaft is driven by achain, s, from the sprocket-wheel upon the engine-shaft.

To the traction-wheels C C are secured sprocket-wheels E E, which are driven by means of chains e e from the sprocketwheels R It.

T T are tanks located one on each side of the machine at the rear of the boiler A.

The traction-wheels C C are formed of sections c c of plate-iron riveted together and to the ilanges g g on hubs G G, as shown in Figs. 3 and 1i, in the form of drn ms, which are watertight. The heads of said wheels are preferably made concave to better resist lateral strain. The hubs G are enlarged at their inner ends and inclose annular chambers H, Figs. 3 and 5, which communicate with the interior of the wheels C C through openings h h, and have in their outer faces openings h h', disposed in circles, as shown in Fig. 3.

I I are hollow rings placed over the axles D D, inside of the wheels C C. Each of said rings is divided transversely by partitions j j into chambers J J', the upper one, J, of which has an opening, k, at the top, and the lower one, J, an opening, Z, at the bottom. On the axles D D are formed two sockets, del, to receive the projections t i on the inner face of the rings I I, and prevent the same from turning with the wheels C C against the inner face of the hubs G Gr, on which they bear. The contiguous bearing-faces of said hubs G G and rings I I are accurately ground or tted to each other, and are retained in close Contact by the set-screws d d and the spiral springs d2 d2 in sockets d d, which, for convenience of illustration, are shown in a vertical plane in Fig. 5. The chambers J J in said rings I I have curved openings in their outer walls, which correspond in diameter with the openings l1. h in hubs G and register therewith, as shown in Fig. 4 and by dotted lines in Figs. 3 and 5.

Inside the wheels C C, on opposite sides thereof and attached to their rims, are buckets F F, from each one of which a pipe, f, curved as shown in Fig. 3, leads to the opposite side of hub G, each communicating with the annular chamber H, formed therein through one of the openings 7i. Exhaust-pipes K K conneet the larger cylinder of the engineB on each side with the upper chambers, J J, of rings I I, and pipesL L, communicating with the lower chambers, J J', of said rings at Z Z lead into the tanks T T, and from the tanks T T pipes M M extend upward and communicate with the exhaustnozzle m, which opens into the smoke-pipe near its base.

P is an air-pump driven through the connecting-rod p by the crank-shaft p,whicl1 is in turn driven from the engine-shalt Q by means of the belt p and pulley p upon said crankshaft. The pump P is connected by a pipe, o, with branches O O, which are coupled each side of the machine with the exhaust-pipes K K. -In place of the air-pump P, a pressureblower or any suitable device for producing an air-blast may obviously be employed without departure from the spirit of my invention.

Between the couplings of pipes O O and K K and the rings I I, to permit aslight adjustment of said rings and the maintenance of perfeet contact between them and the hubs G G, flexible tubes o o are employed.

My improvements operate as follows: The exhaust-steam as it escapes from the cylinder of the engine is conducted by the pipes K K into the upper chambers, J J, of rings I I,

where it escapes through the openings 7L into' chamber H inhub G, and thence through openings h into the wheels C C. That part of the steam which has not been condensed finds its way through the openings hin the lowerpart of the hubs G into the lower chambers, J J, ofsaid rings I, and thence through the pipes L Ljnto tanks T T, from which the uncondensed steam escapes through pipes M M and nozzle m into the smoke-pipe, as shown in Figs. l and 2. The water collecting in wheels C C by the condensation of the steam exhausted into them is caught up by the buckets F F as the wheels revolve in either direction, conducted by pipes ff to and discharged into the lower chambers, J J, of rings I I, whence it escapes at Z Z into pipes L L, which discharge it into tanks T T. The pipes ff, leading from the buckets F F tothe sides of the hubs G G,wi1l continue during the halfrevolution of the wheel C to discharge the water taken up by said buckets into the lower part of the annular chambers H H, and thence into the lower chambers, J J, of rings I I. The air forced by pump P through pipe 0 and branches 0 O mingles with the steam, and as it enters the wheels C C condenses a portion of the steam and escapes with that which remains uncondensed through chambers J and pipes L into tanks T, and thence through pipes M and nozzle m into the smoke-pipe,where itA increases the draft of the furnace.

The form and details of construction of the tankwheels G and of their connections with engines of various kinds may be variously modified without departure from the principle of their opera-tion and the spirit of my invention.

I claiml. In a portable engine, a chamber-ed supA porting-wheel, C, connected with the exhaust of said engine, substantially as and for the purposes set forth.

2. The combination, in a portable engine, of the condenser-wheel C and a bucket, F, arranged to take up the water therein and returnit to the tank, substantially as and for the purposes set forth.

3. The combination, in an engine, of the condenser-wheel C, hub G, ring I, bucket F, and pipe j", connecting said bucket with said hub G, substantially as and for the purposes,

set forth.

4.. The combination, in a portable engine, of the condensing-wheel C, hub G, provided with chamber H, ring I, having chambers J J which communicate with said chamber H, bucket F, applied to the interior of said wheel C and connecting said chamber H, the exhaust-pipe K, connecting the engine with chamber J, and pipe L. leading from chamber J to the tank, substantially as and for the purposes set forth.

5. The combination, in a portable engine, of the condensing-wheel C, exhaust-pipe K, and blower or aiupum p P, communicating through suitable connections with said condenserwheel, substantially as and for the purposes set forth.

6. The combination, in a portable engine, of the condenser-wheels C C, exhaust-pipes K K communicating therewith, and sprocketwheels E E, attached to said wheels C and arranged to be driven by said engine, substantially as and for the purposes set forth.

7. The combination, in a portable engine, of 'the axle D, condensenwheel G, hub G, having chambers H, which communicate with the interior of said wheels through openings ZL, rings I, having chambers J and J, communicating with said chamber H, and provided with projections i t', and sockets cZ Z on said axle D, arranged to receive said projections z' i and springs (Z2, substantially as and for the purposes set forth.

8. The combination, with the engine B, of the traction-wheel G, arranged to be driven thereby and to serve as a condenser therefor, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

C. H. VATEROUS.
