STEAM-ENGINE.

SPECEFICATION forming part of Letters Patent No. 330,494, dated November 17, 1885.

Application filed February 27, 1885. Serial No. 157,174. (No model.)

closure removed, showing the internal arrangement; Fig. 2, an end elevation of the engine, parts being broken away; and Fig. 3 is a side elevation of internal parts of Figs. 1

and 2, indicated by like letters, looking from a point at the left hand of the latter figures.

Referring to the letters marked on the drawings, P P are the radial side inclosures of the steam-chest, joining at the lower end and radiating upward therefrom. The upper inclosure, F, is curved or bowed, representing the fractional portion of a circle, of which these three inclosures, when viewed in end elevation, constitute a sector.

B B are the end inclosures, thus forming a sectoral-shaped steam-chest, inclosed by five walls. These walls, where they join each other, are of course provided with suitable packing or otherwise made steam-tight. The chest is provided with suitable induction and eduction ports entering the chest at any practical points. In Fig. 1 these ports are shown leading through the wall F, at f f. These ports are provided with suitable valves in the usual manner of constructing steam-engines, and as this is so well understood no valves are here shown.

it are bolt-holes in the radial sides P P, through which the bolts are passed which secure the end inclosures, B B. Arock-shaft, a, has suitable bearings at the juncture of the radial inclosures P P, with only a portion of the rock-shaft confined by said bearings, the upper periphery being exposed within the chamber of the chest.

R R. The ends of the shaft to do not have bearings, the bearing of the shaft a Within the 55 chest when suitably packed or bushed, as above described, being far preferable for trueness of movement and simplicity. The con'nectingrod r is here shown broken away,

it not being deemed necessary to show the connection of these rods with the drivingshaft of the engine, which shaft, in the arrangement here shown, would be located at some suitable point at the right hand of the steam-chest. By connecting a crank, R, with each end of the shaft for driving another shaft by means of connecting rods, no bearings are needed at each end of the shaft a, as the strain is equally distributed and the engine has greater power with less liability to get out of order as compared to such shafts having a crank at one end only. The broken arms A show the connection of a support with the steam-chest. The use of these arms and certain novel features of the driving-shaft (not 7 5 here shown) are to form the subject-matter of a future application 5 hence the details are not here given. Between the lower end of the crank R and the wall B of the chest a suitable stuffing-box may be employed. (Not here shown.) Within the chest is a steam-actuated plate, D, rigidly secured to the rockshaft a and radiating therefrom to the bowed wall above. This plate is of a size to loosely engage with the interior surfaces of the walls B B and F, so that the plate may be oscillated from one radial side of the chest to the other by the inducted steam through suitable ports on each side, and thus rock the shaft a, with which said plate is connected. This action 0 imparts reciprocating motion to the connecting-rods a".

It will be understood that the edges of the plate D may be provided with any suitable packing to make the engagement of the edges with the walls of the chest steam-tight.
