IMPROVEMENT m s'ra AM- LAMP-CARRIAGES.

'l'he Schedule referred to in the Letter: Futons and ranking put of the same.

I, Jnnoa'rn B. McKInLnY, of the county of Spencer and State of Kentucky, have invented a certain new and useful Improvement in a Steam Land-Can riage, of which the following is a specification.

Thc'first part 'of my invention consists in a car- 'i-iage mounted on three wheels, somewhat similar to that of, thecommon steam fire-engine, except that the body may be made in any suitable form, having lougslot openings in each side,i'n order to receive the bearing-boxes of the hind axle, with gum springs over them; their boxes are all neatly fitted in the lower end of these openings, so as to slide up and down, as the spring yields, in passing over rough roads; the back end of this body is provided with a convenient seat for the operator, the lower part. of which is made to answer as a \lftlifil'ditllk, with the force-pump that supplies the boiler with water immediately under it. This pump is operated by an eccentric on the hnbof the main wheel by means of arbor-shaft, and'nrms connecting with the pump. And immediately in frOnt of the drivers seat withinthcearriagc is the arrangement for steering the machine, consistiugofiasmallshaft working down through a pipe-shaped stand secured to the floor of the ear, the upper end' of this shaft being-provided with a lever, in order to operate it, while the lever and has a double clank connected with the revolving platform of the front wheel, by means of iron rods, by which the machine is guided; but in order to regulate the speed of the machine it is provided with brakes similar to those now in use, witha lever extending up through the bottom of the car so as to be operated by thefoot of the driver.

The second part of my invention consists in the general arrangement of the front wheel. This front wheel is madc somewhat similar to that of a common wheelbarrow, except that the shaft projects beyond the bearings, and is provided with cranks on each end set at right angles, the bearing-boxes of this shaft being neatly fitted into slot opcningsin the lower end of long horns secured to the under side of the revolving platform, so as to slide up and down'in the open-. ings as the gum spring over them yields tothe shock in passingover rough roads, there being openings in the above platibrm for. the connecting rods of thc engines to pass through.

The third part of my invention relates more espe cially'to the peculiararrangement of the engines on the revolving platform of the front wheel, they'being what is commonly called double engines, constructed andQarranged much similar to those now in common use, except that they are inverted so that the pistonrodworks out below, the pitmen-of which connect with thecranks of the wbeel-shaftbelow, tb.e bearingboxes of the shaft and cylinders bc permanently connected by means of an iron bar passing up through the spring" connecting with the head of the cylinders, which cylinders are made to slide in fixed stands on top of the platform by means of grooves cut in the head-flanges, so as to enable them to yield to the working of the springs below; and asthe. springsdo not always work together, consequently me steampipe connection between them must be made of gum, so as to accommodate itself to the irregularity. The steam-pipe connecting the engine with the boiler can be made of any suitable material, but with a'packing box at each end, the end over the cylinder forming a swivel-joint in order to permit the wheel to turn entirely round so as to back the machine, when desirable to so arrange it for that purpose.

The boiler for generating the steam is placed in the car immediately behind the engine. I

One may be constructed in any of the knownforms suitable for the purpose. 1

Having thus fully described the nature of my invention, a more complete understanding of which may be had by reference to the drawing,

Figure 1 is a view of the machine complete, with one side out out in order to show the interior arrangement of the machinery therein. 1

Figure 2 is a view of the bottom, showing the forcepump and the machinery for guiding the car.

A A are the engine cylinders. 13 B are the stands or slides to which they are attached.

(J G are the connections between the cylinders and journal-boxes of the shaft. I

D D are-the cross-heads, to which the piston-rods and pitmen are attached.

E is the cranks of the wheelmhaft. I 1 is the gum springs and journal boxes of the same:

G is the front wheel. y f I K is the eccentrics that work the valve of the engines.

H is the exhaust. I is the connecting steam-pipe between the cylinders.

M is the steam-pipe connecting with the boiler,

, N is the boiler.

i O is the chimney. I k

l l is the stand post by which the machine is i guided. I I

. Q is the foot-lever of the brake.

It is the rubber of the brake.

S is the main wheels of the machine.

I T is the eccentrics for working the. force-pumps.

U is the shaft by which motion is transmitted to work the pumps.

V is the body of the car.

and dine,

' W' is the driveis seat and water-box.

' X is the-gum springs over the main axle-boxes.

Y is the force-pump. I

Z Z are the pipes connecting it with the water-box and holler.

B is the double crank of the steering-post.

A A are the links connecting it with therevolving platform L by which the maehlne is guided.

Having thus fully described the drawing.-

VVhet lpclalm as new, and desire to secure by Letters Patent, is

1. 'lhe'sliding stezun-oy'liuders A A, and stands B B in whieh they work; also the connections 0 C between the lower endof the cylindeis and journalboxes, in combination with the cross-heads D D, the eccentrics K, cranks E, gum springs F, wheel G, fend platform L also the pipes H, I, and M, the boiler N, and chimneys); also the force-pump Y with its pipe substantially as and for the'purpose hereinbefore set orth.

' 3. The combination of the wheel S the gum spring- X, the brakes B, with their foot-lever Q, and body V, with its sent and water-box W, when arranged, eonstruetecl, and operated, substantially as and for the purpose hereinbefore set forth.
