UNITED STATES- PATENT OFFICE.
FREDERICK F. scHoFIELD, oF oscoDA, MICHIGAN.
lMPRovEMENT IVN RoTARv ENGINES.
Specification forming part of Letters Patent N o. 182,291, dated September 19, 1876; application filed July 15, 1876.
To all whom-it may concern:
Be it known that I, FREDERICK F. Sono- FIELD, ot Oscoda, in the county ot' Iosco and State of Michigan, have invented a new and valuable Improvementin Rotary Engines 5 and I dohereby declarethat the following is a full,
clear, and exact description of the construe-- tion and operation of the same, reference being `had to the annexed drawings, making a part of this specification, and to the letters' and figures of reference marked thereon.
Figure l of the drawing isarepresentation of a side elevation of my invention.` Fig. 2 is a View showing the interior of the casing.
' Fig. 3 is a longitudinal sectional View of the hub, taken on line m w of Fig. 4I; and Fig. 4 is a detached view of the hub and hollow shaft.
In the accompanying drawings, A repre-l sents a cylindrical casing, into which the steam or water is introduced for the rotation of the same. This casingl A is 4cast or other- Wise formed with an external rim, B, strengthened by webs or arms a, so that open spaces a are formed to allow the free circulation ot' the cold air through the sa|ne,which keeps the rim B cool, and thereby prevents the belt over which it is placed from becoming dry and hard from the heat, which would cause it to slip. The rim B may also serve as a iiywheel. Two small chambers, b, connect the rim B with the casing, and are arranged on a line opposite each other to receive the abutments c, which are kept pressed against the outer periphery or rim of a stationary hub, (I, by springs d. The hub C is rigidly connected to, or forms a part of, a hollow shaft, D, provided with a supply-port, e, and an exhaustport, j', the two being divided or separated by a partition, so that they may each concasing A. The hubG has grooves i formed near its pointed end to allowthe steam orl `water to act upon both abutments ,0, so as to obtainincreased power, and insure it striking the abutments immediately at that point where it starts down the incline, and thereby avoiding any. back pressure by allowing sufficient time for the steam or water to escape. The .hub C is hung eccentrically with the axis of the hollow shaft D, and has a packing, j, which is kept pressed against the interior ofthe casing A by aA suitable spring. This packing, with the assistance ot' the abutments c, divides the interior of the casing A into two chambers for the introduction and escape of the steam or water, the packing j also keeping the steamvor water from passing throughto the exhaust-chamber.
The casing A is formed with interior screwthreadsfor securely attachingl suitable caps E, said caps having screw-threaded flanges for the reception of packingrings 7c, thereby making a perfectly water-tight chamber.
The ends of the hollow shaft D are supported in standards F, and securely held therein by set-screws l.
By my invention the parts are few and simple in construction, and consequently not easily gotten out ot' order, while its action is uniform with comparatively little friction, and can be readily placed in any position without in the least affecting its operation and. powert.
Having now fully described my invention,
what I claim as new, and desire to secure by y Letters Patent, isl The rotary casing A, formed with rim B, Webs or arms a, and air-spaces a', and abut; ments 0, in combination with thestationary hub C, formed with passages g h and grooves t', and the hollow shaft D, having supply and exhaust ports ef, the whole constructed and arranged to operate as 'set forth.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
