HENRY JAMIESON, 0F WILLIAMSBURG, NEW YORK.
Letters Patent No. 108,148, dated October 11, 187i).
IMPROVEMENT IN `ROTARY ENGINES'.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that I, HENRY JAMIEsolv, of Williamsburg, in the county of Kings and State of New York, have invented a new and improved Rotary En gine; and I do hereby declare lthat the following is va/full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which Figure 1 represents a front elevation of' my irnproved rotary engine.
Figure 2 is a vertical transverse section of the saine, taken on'the plane of the line x a', fig. 1.
Figure 3 is a hack view, partly in section of the same.
Figured is adetail front elevation, partly in section, of the saine. v
Similar letters of reference indicate corresponding parts.
My invention relates to rotary engines, and consists in improved means forreversing. the steam inlet-valve.
A in the drawing represents the stationary cylindrical case or shell of the rotary engine.
B is the rotary piston, mounted upon the drivingshaft C, and provided with a projecting ange,1c, that receives the steam pressure. All these parts are of suitable construction. A
In lthe upper, part of the case A, is arranged the inlet-pipe a, and the inlet-valve D.
The valve D is of cylindrical form, but has its lower part cnt away and concave, as shown in fig. 3.
The concave lower face of the valve corresponds in its curve with that of the inner face of the shell, and serves to replace so much of the same as is cut away for the admission of the valve.
The valve D is provided with a steam channel, l, open at both ends, the middle part of' said channel being at c, in uninterrupted communication with the steam supply-pipe a.
The valve D is mounted upon a horizontal arbor, (l, which is hung in the shell or caso A, and which, on the outside of the steam-chamber, carries two proprojecting arms, e and f, as is clearly shown in figs.
, 1 and 4.
By means of an arm, g, the arbor is connected with a sliding rod, E, that is arranged on the outer part of the case.
This rod carries two springs, la and i, one on each side of the arm g.
Vhen the rod E is moved in one direction, and locked by a pin, j, to one of its supporting-ears k, so
as to compress the spring i, such spring will, by its power, hold the arm g to one side, and swing the valve D accordingly. The valve will thereby be held with one corner against the piston, as shown in fig. 3, and one end of its steam channel b is held open-to admit steam to the case A.
The valve forms the partition within the annular steam-chamber for preventing the steam from going hack.
The case A is provided with two exhaust-pipes, l and on, each having a valve, n.'
Then the valve D is in the position shown in lig.
3, the port l behindit must beopened, and the other an, closed. The steam will then enter the steam-channel through the port b, and press against the ange c for rotating the pist-on. As the ange arrives again under the valve D, the steam will escape through the port l, b'ut will retain enough power to carry the flange past the valve D.
While the-ange w passes under the valve,the
latter must be swung, so as'to bring the concave portion of its face in line with the circumference of the steam-chamber.
It is swung into this position by means of a cam,
p, mounted upon the shaft C, and striking the arm e.
The cam p will carry the valve clear of the flange n', and will retain the same in that position until the ila'nge has passed. lhen the spring i will again draw the valve into the former position.
For reversing the motion of the engine, the rod E is movedso as to .compress the spring h, whereby the valve D will be swung wit-h its other end down, to conduct the steam against the opposite face of the flange w. A
rIhe port l is closed, and on opened, which is done by swinging a rod, F, that connects the cranks 'r of the two exhaust-valves.
The action will he the same as above described, except that t-he motion of the valve for clearing the flange -w is produced by another cam, s, on the shaft 0, which strike'srthc arm f.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The arrangement of the sliding rod E, springs h t and arm y, to reverse the shaft and valve, as set forth.
HENRY J AMIESON.
