Definitions

  • a vessel which, to move at a given speed, would require an engine of one hundred horse power would, un er such conditions, only require an en gine necessary to produce the compression of the mixture the work produced by the explosion of which would be equal to one hundred'horse power, so that there are secured economy in rice, weight and space occu ied, besides tiie consequent increased faci 1ty of manipulation.
  • Propulsion by reaction has other advantages; for example, a propeller screw is no longer necessary; a vessel so propelled can move with equal ease in either.
  • the rudder may be ispensed with, a condition which, concurrently with the absence of the screw, obviates frequent causes of grounding. With such an engine moreover a vessel is capable of moving more readily from one position to another.
  • Figure 1 is a? dia rammatic plan view of a vessel adapted to o driven by the exhaust from an ex loder;
  • Figs. 2 and 3 are respectively an e evation and a lan of a battery of exploders;
  • Fig. 4 is a iagrammatic elevation of a compressor motor having three cylinders mounted in tandem;
  • Fig. 5 is a plan of a modified compressor motor comprising six cylinders;
  • Flg. 6 is .an elevation partly in section of a modified arrangement of reaction pipes;
  • Fig. 8 1s a dia am matic plan of a vessel ada ted to be riven by the exhaust from a hydrocarbon motor
  • Fig. 9 is a similar view of a modified arrangement.
  • the motive force em loyed is the explosion of poor gas derive from a gas producer A and compressed by a motor gas compressor B into a gas accumulator C under a pressure of about 20 (twenty) atmospheres; a second compressor B for air forces air at the same pressure into an air accumulator C
  • the explosion takes place in a battery of exploders D of which one is shown separately in Figs. 2 and 3.
  • These ex loders are fed with a mixture of. gas and air from the respective accumulators G and C throu h admission valves d and 03 respectively; t e pressure of the mixture is reduced by means of suitable reducing valves'to about six atmospheres and its composition consists of one part gas and five parts air.
  • a motor E drives a shaft (13 which controls the distribution of air and gas to the exploders and,
  • the motor compressor B see Fig. 4, comprises three cylinders mounted in tandem; the two extreme cylinders T and J are motor cylinders and the middle cylinder K is a compressor cylinder.
  • the motor cylinders I J are provided on each side-with two admission valves 2', i 51, f for as and air, and with an exhaust valve '5 33 or the products of the explosion; the compressor cylinder K has only one gas or air admission it is a gas or air compressor, and one exhaust valve 70 for the gas or compressed air which passes to the accumulator.
  • the pistons o the three cylinders iston rod L which has a to and fro recti inear movement imparted to it.
  • Fig. 4 The method employed for o eratin the distribution valves of the cylin ers I, K, is diagrammatically indicated in Fig. 4 where 1t will be seen that disks M are actuated by tappets Z on the common piston rod and links Z connecting the disks M to the difierent valves.
  • the starting of the motor compressor is effected by means of compressed air derived from the accumulator.
  • Fig. 5 shows a compressor motor 3 having six cylinders formed in two groups of three cylinders each mounted in tandem.
  • Each group comprises two motor cylinders constituted by the outside cylinders T and J, and one intermediate compression cylinder K.
  • the arrangement of the admis sion and exhaust valves in the difi'erent cylinders is the same as in Fig. at and in each group the pistons of the three cylinders in tandem are mounted, as hereinbefore described, on one common piston rod L.
  • the working phases in the motor cylinders are crossed thereis always a motor movement per group of cylinders, or two movements per stroke, one in the opposite direction to the other.
  • the motor B shown in Figs. 4 and 5 may be arranged so as to avoid the use ofthe exploders. For this purpose it sufiices to make the intermediate cylinders K motor cylinders and to adm1t an explosive mixture thereto. This mixture is fired and the products of the combustion escape immediately after the explosion to react upon the water without the intermediation of exploders; it is necessary that there should be in the cylinder a difference in the angles of keying of the unclicking tappets.
  • the motors of this arrangement may likewise work on the principle of gas motors or else according to the principle. of Diesel motors. 1
  • FIG. 7 Another arrangement for'avoiding the use of exploders is indicated diagrammatically in Fig. 7 It comprises a motor composed of four cylinders N N N, N the pistons of which act upon a common shaft N which is mounted to rotate in bearings 91.. This shaft is cranked for the cylinder piston rods at the middle N and N and at its ex- 'tremities, it is provided with ,c'ranks connected to rods 71. a
  • Fig. 7 shows the cylinder N at t e end of its suction stroke, the cylinder N is at the end of its compression stroke, the cylinder N at the end of its expansion stroke and the c linder N at the end of its expulsion stro e.
  • the dimensions of the fly wheel may thus be reduced to a minimum.
  • the motor shown in Fig. 7 may work according to the principle of either explosion motors, combustion motors, or Diesel motors.
  • Fig. 7 is a diagram of .the four cylinder motor of Fig. 7 working after the princfifple of explosion motors.
  • Thisdiagram di ers from that of an ordinary explosion motor, in that the exhaust valve is opened b means of the distribution rod, immediate y after the explosion. From an to 3 there is a sudden fall of pressure, the ases issuing from the cylinder to exercise tieir pressure upon the water. At the valve will be closed and the pressure re need to such a value that it can accomplish sufficient work to compress the explosive mixture in the cylinder where compression takes place and to overcome the passive resistances. The expulsion of the gases takes place on the fourth stroke by another exhaust valve likewise worked by the distribution rod and communicating with the atmosphere.
  • the explosive gases are derived from somesuitable hydrocarbon, such as petrol for example, contained in reservoirs P and forced by a petrol compressor B into the exploders D at a pressure of 30 (thirty) atmospheres.
  • the exploders are previously filled with air at the same pressure derived from an air accumulator O which is fed by an air compressor B.
  • the ex loders' are not fitted'with magnetos. The istribution of fluid to and from the exploders is. 'efi'ected as in the first described arrangement. r
  • Air derived from an air accumulator Cl enters into petrol reservoirs P at a pressure of 6 (six) atmospheres and is then delivered by means of Injectors into the exploders D where explosion is caused by means of magnetos; the use of a petrol compressor is thus dispensed with.
  • the pressure of the air in the accumulator C may be from 50 to 60 fifty to sixty) atmospheres and it is reduce by suitable reducing valves.
  • a lurality of explosion chambers indepen ent accumulators for gas and air with passages leading to each of said chambers, means for compressing gas and air in said accumulators at a relatively high pressure, and means for admitting said gas and air at reduced pressure to said'explosion chambers, in combination with a common exhaust passage-into which said chambers open and forwardl and backwardly directed passa es branc ing from said exhaust to the exterlor of said vessel, substantially as and for the purpose descrlbed.
