SECIFICATION forming part of Letters Patent No. 398,456, dated February 26, 1889.

Application iled November 1l, 1887. Serial No. 254,940. (No model.)

T0 all whom it may concern:

Be it known that l, JOHN A. SECOR, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Engines, of which the following is a specification.

My invention relates particularly to en gines employed for the propulsion of vessels, butis not confined in this application to such engines.

I will describe an engine embodying my improvement, and then point out the various novel features in claims.

In the accompanying drawings, Figure l is a vertical longitudinal section of an engine embodying my improvement, and of a portion of a vessel containing such engine. Fig. 2 is a plan or top view of the engine. Fig. 3 is a central longitudinal section of a device for spraying a hydrocarbon employed in the operation of the engine. Fig. i is a face view of valves controlling the operation of the engine, said view including certain appurte- Fig. 5 is a face view i nances of said valves. of an automatically-operating valve which is included in the engine, and this view also includes certain appurtenances of this valve.

Fig. 6 is a verticallongitudinal section of certain partsl of the engine, incl udin g this automatic valve.

Similar letters of reference designate corresponding parts in all the figures.

A designates the stern portion el' a vessel,

which maybe of any suitable type. A designates the rudder thereof.

B designates a chamber, which may be made of any suitable metal, and which is arranged in the lower part of the stern portion of the ln the chamber B explosions are re! chamber has combined with it a valve, l). At the forward end it has combined with it a similar valve, B2.

Then it is desired that the This chamber B is vessel shall be propelled forwardly, the valve B2 must be closed and the valve B opened.

The valves B B2 may be operated through the agency of any suitable mechanism. l have shown the valve B fitted in a slideway, b', so that it can be adjusted vertically therein. Part of this slideway is made in the form of a trunk extending` above the chamber The valve B is provided with a rod, which extends up through a stuffing-box with which the trunk is provided. This rod is shown as connected to a cord or chain, b2. This cord or chain passes around a pulley, b3, and thence extends to the lower end of a lever, lf. The lever D is fulcrumed to a stand, h5, and is provided witlr'a'loclzing-catch, h6, whereby the lever may be locked in different positions to the stand. The valve-rod is also attached to a cord or chain, 117, which passes around pulleys bs b9, and is attached to a weight, bw. This weight partially counterbalances the valve B', so as to reduce the labor of operating the lever h4.

The lever h4 may be arranged in the pilotroom of the vessel, and it is intended to be represented as in a position accessible to the pilot. It may, however, be arranged elsewhere, if preferred. This mechanism provides for opening and closing the valve B at pleasure.

The Valve B2 is shown as operated in the same manner as the valve B it having connected to its rod a cord or chain, hm, which passes around a pulley, D15, and is connected to a lever, bw'. The lever h1 is combined with a stand, bl?, and locking-piece bw. The lever Z916 is intended to be arranged close to the lever h4.

l have shown at the forward extremity of the chamber B a gate, B3, which is hinged at the rear end to the chamber and connected at the forward end by a link, h, with a screwrod, hm, that extends upwardly into the ve. sel through a stuftingbox with which the chamber is provided. A nut, Z113, is combined with the screw-rod, so that by rotating this nut the gate B3 may be lowered or raised to open or close the forward end of the chamber B. The forward portion of the chamber B is so bent or extended that, in conjunction with the gate B3, when lowered at an angle to the vessel, it will direct the force produced by explosions within the chamber B properly to effect a rearward motion of the vessel. The gate B3, instead of being operated by the mechanism described, might be operated by a cord or chain and lever in amanner similar to the valves B' B2.

The valves B 32, which I have already referred to, are, as it will have been understood, intended to operate solely at the will of an attendant. The chamber B has also combined with it valves C C2, which are intended to operate automatically. The valves C' will operate only when the valve B' is open, and the valves C2 will operate only when the valve B2 and gate B3 are open. The object of the Valves C' C2 is to permit of the force of an explosion to be exerted upon the water at either end of the chamber B, and yet to prevent the subsequent influx of water into the chamber. Therefore these valves C C2 open outwardly under the influence of the force produced within the chamber, and close inwardly when acted upon by the force of the water outside the chamber.

e The construction of the valves C' C2 is somewhat peculiar. As the valves C' C2 are alike in construction, it will be necessary to describe but one in detail, and this may be done best by reference to Figs. 5 and 6, where the valves C' are shown on an enlarged scale.

c designates a frame, preferably madeof metal and composed of two upright rails and`three cross-rails, two of which connect the ends dfthe upright rails, and the third of which extends between the upright rails equidistant from their ends. The frame therefore has two rectangular openings. This frame c fits at the edges in recesses in the side walls and the bottom wall of the chamber B. It also extends upwardlyinto a trunk, Z318, with which the chamber is provided. A vscrew-rod, c', is connected to the frame c and extends through a stuffing-box, with which the upper part of the trunk Z218 is provided. Above the stuffingbox a nut, c2, is located. This nut engages with the screw-rod, so that by manipulating the nut the screw-rod may be made to raise the frame c wholly into the trunk, if desired, and to lower it into its normal position.

The valves C' are connected to the frame c. The upper valve C is connectedv at its upper edge to the top rail of the frame c. The lower valve C is connected at its lower edge to the lower rail of the frame c. Both of the valves C close against the middle rail of the frame c. Each of the valves C is composed of a thick sheet of india-rubber, c3, a sheet of leather, c, arranged adjacent to that side of the sheet of india-rubber c3 which is next the frame c, a plateof sheet-iron, c5, arranged against the piece of leather, a block or piece of wood, c, arranged adjacent to the other side of the sheet of india-rubber, and a plate of sheetiron, c7, arranged against the outer side of the piece of wood. The plate of sheet-iron c5 is of such size that it will not come in contact with the frame c, but may pass into an openingI thereof when the valve of which it forms part is closed. I have found that this combination of materials is of great importance in making the valves C' C2 for my engine. The rubber, through its elasticity, saves the other parts. rIhe leather protects the rubber, and the rubber, by preventing the leather from receiving concussions of the violence to which it would otherwise be subject, renders the leather durable. The sheet-iron and the wood stiffen the valves, besides protecting the surfaces of the Aleather and rubber. The various parts composing each of these valves may be secured together by means of screw-bolts and nuts or other analogous devices.

D designates a compressed-air reservoir. It is connected by a pipe, D', with an inj ector, E, that communicates with the chamber B. As shown, this pipe extends from one end of the reservoir D to the injector E, and

the latter communicates with the upper portion of the chamber B. The pipe D' is provided near the chamber B with a check-valve, d', which opens toward the chamber B, but closes in the reverse direction, so that any force or pressure of gas which may be generated will close the valve and cut off the pipe AD from the chamber. The pipe D is also provided with a hand-cock, cl2, whereby it may be closed when the engine is out of use.

F designates a receptacle containing a hydrocarbon-such, for instance, as kerosene. lt is connected by a pipe, F', to the injector \.\This pipe is shown as extending from the lower portion of the receptacle F to the injector E, and as being provided near the injector E` with a checkvalve, f, which will open toward the injector E and chamber B, but will close in the reverse direction, so as to exclude from the p ipeF' and receptacle F any force or pressure of gases which may be generated in the chamber B.

The injector E consists of a shell, e, a piece,

e', fitted in the end of the shell e, whichis the farthest from the pipe D', and a piece, e2, fitted into the shell e. The piece e is provided with two tapering portions which are largest at t-he ends of the piece, and which at their IOO smaller diameters meet and communicate;`\

The piece e2 extends into one of the tapering- ',-.icavities of the piece e', and itself has a taper` ing hole throughout its length. It will be seen that the diameter of the outlet of the;` piece e2 is less than the smallest diameterof' rzof the iece e'. The s ace between the piece 'civ f and the tapering cavities of the piece e', into' which it extends, communicates with the pipe F', leading' from the hydrocarbon-receptacle F. The interior of the piece e2 communicates with ythe pipe D', leading from the air-reservoir D. The force of the compressed air will draw the hydrocarbon into the injector, and, owiu g to the peculiar construction ofthe piece e', will dash the hydrocarbon into "a spray'.- In the form of the spray the hydrocarbon enters the chamber B with the compressed air.

the hydrocarbon and the air within the chainber B may be periodically exploded.

. G designates a' source of electricity. It may be a battery or a dynamo-electric machine.

G designates wires extending from the poles of the electric generator to two electrodes, G2 G3. These electrodes extend through the wall ot the chamber B, and are adapted to contact with each other within said chamber. They are in sul ated from the chamber and from each other. The electrode Gs is stationary. The electrode G2 is, however, vertically movable, in order that its inner end, which is bent upwardly toward the inner end of the electrode G3, maybe made to contact with the electrode G3, or may be separated from the latter, as occasion may require. It is intended that normally the electrodes shall be in contact, and that they shall be separated at the proper times to produce sparks, whereby the air and sprayed or vaporized hydrocarbon within the chamber B may be ignited. I will defer a description of the means whereby the separation of the electrodes and their subsequent con ,.f tacting are effected until after I shall have described certain other parts which produce i the movements of the shifting electrode.

H designates a cylinder connected at one end by a pipe, H', with the compressedair reservoir D. The pipe Ii is provided near the cylinder H with a' check-valve, H2, which will open toward the reservoir D, but will close so as to prevent the passage of compressed air from the reservoir to the cylinder.

IVithin the cylinder H a piston, H3, is arranged. One end of the cylinder communicates with the chamber B, and whenever an explosionoccurs in the chamber the piston l-l3 is forced thereby toward the end olf the cylinder which is the farthest from the cham ber. The movement of the piston in this direction compresses the air which is in advance ot it and forces it Vthrough the pipe H into the reservoir D. `Atterthe force created by an explosion in the chamber B shall have been expended in the propulsiim of the vessel, and the pressure within the chamber shall have been very greatly reduced in consequence thereof, an in let-valve, Hwiih which the cylinder is provided in the end farthest from the chamber B, will open, and the air at atmospheric pressure, thus permitted to iiow into the cylinder, willv force the piston toward the other end ot the cylinder. The piston, in the manner described, reciprocates once for each explosion that may occur in the chamber l5. The. piston is provided with a rod passing through a stuttiugbox arranged at one end ot' the cylinder. The pis ton-rod is connected outside the cylinder with a lever, I. This lever will be vibrated once tor each reciproeation ot the piston. A cord or chain, I,` is connected at one end to the lever I, passes around a pulley, I2, and is connected to one end ot a spring, I3. The spring I3 at the other end is connected to the I will now describe an apparatus whereby l outer end of the movable electrode G2 of the igniting apparatus. The spring I3, as shown, is of helical form. Then the lever I is vibrated by the piston H et the air-compressing engine in one direction, it will allow the movable electrode G2 to descend and break contact with the fixed electrode G, and when the lever I is `vibrated in the reverse direction the movable electrode will be, raised into contact with the lined electrode.

The movable electrode requires but a short movement. The piston oi the air-compressing engine has a "much greater movement than is necessary for the movement of the movable electrode. Consequently the piston ot the ai r-compressing engine is connected to the lever I as far as possible from the i'ul crum ot the lever, and the cord or chain I isV connected to the lever close by its fulcrum.

The spring I3 will be kept under tension during almost the entire operation of the lever I; but just before the lever shall have completed its movement in one direction the spring will have been relieved of tension, and during the remainder of this movement oit' the lever the movable electrode will be al lowed to fall. The parts have been represented in Fig. 1 in the positions which they occupy just betere the final movement of the piston ot the air-compressing engine in one direction, whereby the movable electrode is lowered.

Then an explosion occurs in the chamber B, the valves C or C2, according as they may be in operation, will open outwardly and permit the force generated by the explosion to act upon the water adjacent to said valves. Immediately after the force of the explosion shall have been expended the valve will close and prevent the ingress ot water into the chamber.

The chamber B is provided with whatI term an air-inlet, B4. This consists ot' a passage or conduit arranged above but eommunicat` ing at the ends with the chamber B. It has 1 erforations in one wall, and combined with these perforations are valves B5, which are held to their seats by springs and by whatever pressure there may be within the chamber, but which open under the influence oi' the atmosphere outside of the chamber whenever the pressure within the chamber shall bc reduced below atmospheric pressure.

I have described the various parts as though there were but one propelling-engine. I desire it to be understood that there may be any nnmberof these propellingengines. In Fig. 2 I have shown two arranged side by side. These two engines are arranged one on each side ot` Athe central longitudinal line of the vessel. hach will prefcral )ly be provided with independent mechanism for operating the valves B B2 B3. When so provided with independent valve-operating mechanism, the vessel may be steered by the engines with or without the aid of a rudder. For instance,

if it is desired to turn the vessel to port, the

starboard engine would have its valves opened and be rendered operative, and the port engine would have its valves closed and be rendered inoperative, or else would have its valves adjusted and be rendered operative to force 1 the vessel backward. To iurn the vessel to starboard, the engines would be operated just the reverse of the'operation just described.

What I claim as my invention, and desire to secure by Letters Patent, is-
