I "NITED n STATES PATIENT OFFICE. A
KINGsLEY n. oLMsTED, oF CHICAGO, ILLINOIS.
REACTION PROPELLER-WHEEL.
SPECIFICATION forming part of Letters Patent No. 230,566, dated July 27, 1880.
I Application filed April 5, 1880. (No model.)
To all whom it may concern:
Be it known that I, KvrNGsLEY R. OLMsrED, of the city of Chicago, county of Cook, and
State of Illinois, have invented certain Im provements in Reaction Propeller-VVheels, of which the following is a specification.
The object of my invention is to utilize the reactionary power lof steam, 'compressed air, or any like motor, when ejected from the blades 'of a four-bladed screw-propeller under water,
. panying drawings, in which- Figure l represents an elevation of a screwpropeller in connection with a portion of the hull of a boat; Fig. 3, a transverse vertical section of a screw propeller, as indicated by the broken line in Fig. l, Fig. l, a longitudinal vertical central section ofthe whole apparatus, and Fig. 4t a detail perspective of the tubular valve I).
A is a lever pivoted in bracket, B, which is fastened upon cylinder C, and its foot is seated' in a depression in the end of valve-shaft.
D is the outer bearing for the journal i of the propeller-wheel; E, the hub of the same,
and c c w w its four blades.
b is the tubular sliding` valves, seated in a suitable chamber in the center of the hub E, and it is provided upon its outer surface with a slot, S, of sufficient depth and length, in order that its lengthwise motion may be limited by the set-screw h, inserted into it through the hub E, and the setscrew will prevent the valves from revolving in the hub, and cause it to revolve with it.' The valveis also provided with two sets or pairs of port-holes, d d and c c, to correspond with the portsfin the two pairs of blades c /v and w w, so that when the valve is in o ne eXtreme position steam will be admitted into one pair of blades to' drive the boat forward; but when it is in the other eX- treme position steam will be admitted into the other pair of blades to drive the boat backward.
The valve b is operated by the valve-shaft q, which is provided with a stuffing-box, p,
upon one end of cylinder C, while the other end is attached to the valve itself.
The steam is admitted into cylinder 0 through the induction-pipe a, and a steamtight connection is made between it and the' sleevel n by means of the stationary nipple o, and the sleeve allows the passage of the steam through the shell or hull D of the vessel, and
jam-nuts m and l on either side hold the sleeve firmly in position, and the connection is made between the sleeve and hub E of the wheel lby means of rey'olving` nipple J, and the joint Perforations g g and u u are made in the sides of the ends of the blades for the discharge ofthe steam, so that jets of steam shall issue from the blades perpendicular to the axis of the wheel and tangential to the circles described by the blades, and the said perforations are so arranged, as shown in Fig. 3,.that the jets from the pai-r of blades w w shall strike the water in exactly opposite directions from those issuing from the pair ot' blades c c.
It 1nay`be"seen from Fig. 2 that my devices can be operated from within the vessel, that my cylinder C does not revolve, and that the bearing for my screw-propeller, the journal z', and the revolving nipple J are outside ofthe boat and in the water, where they are cooled and lubricated thereby.
The only motion the valve b has in relation to hub E is the back and forward one to start and reverse the propeller, and therefore it will bear servicea long time, which would not be the case if it revolved in the hub itself.
What I claim as my invention, and desire to secure by Letters Patent, is-
' 1. A screw-propeller having two pairs of blades, the blades of each pair being in the same straight line, and provided with ports f and side orifices, g and u, and in combination with sliding valve b, having two pairs or sets of ports therein, so arranged that by moving` the valve forward or vbackward steam may be IOO admitted into either pair of blades at Will, lche lever A, having fulerum B, by which the substantially as described. same may be operated, and the sliding valve 2. The sliding valve b, provided with one or b, with its `iL/Wo sets of portholes` e and d, more vent-holes, e, in its outer end, in eombiadapted to admit steam into either pair of the f5 5 nation, with its chamber in hub E, when that blades of the propeller at Will, as required,
chamber is provided ,with a sufeieut stealnsubstantially as described.
space behind the valve adapted to render the KINGSLEY RAY OLMSTED' valve so balanced as to be moved with au equal amount of force either Way, substantially as Witnesses: 1o described. BAILEY D. DAWSON, 3. The combination of the valve-rod g aud BENTON VAN DYKE.
