JOHAN MATHIAS KAREL PENNINK, OF HAARLEM, NETHERLANDS.

HIGH AND LOW PRESSUR GAS-GENERATOR.

SPECIFICATION formingpart of Letters Patent No. 550,526, dated November 26, 1895.

Application filed March 13, 1895.

To all whom t may concern:

Be it known that I, .I oHAN MATHIAs KAREL PENNINK, a citizen of the Kingdom of the Netherlands, residing at Haarlem, in the Netherlands, have invented a new and useful High` and Low Pressure Gas-Generator, of which the following is a specification.

My invention relates to an apparatus into which compressed explosive mixture, say, of combustible gas and air or a similar mixture is continually fed,`whereupon the mixture is successively exploded in certain chambers of revolving drums and the explosion products escape partly into a first line of pipes and partly into a second line of piping. The products of the explosion being nearly continually discharged into the said two pipe systems, a stream of high-pressure gas is obtained by the first pipe-line and a stream of low-pressure gas by theV second pipesline. These two kinds of gas are separately conducted in a similar manner as steam or compressed-air to sundry engines, injectors, and so on, for the purpose of driving or acting the same. I attain this object by the mechanism illustrated by the accompanying six sheets of drawings, of which- Figure l is a vertical longitudinal section of the apparatus, taken in.the plane of the line m n in Fig. 8; Fig. 2, a horizontal section taken in the plane of the line o 19 in Fig. l; Fig. 3, a vertical cross-section on the line g r in Fig. l; Fig. 4, a vertical cross-section on the line s t in Fig. l; Fig. 5, a vertical crosssection on the line u o in Fig. l; Fig. 6, a vertical cross-section on the line -w in Fig. l; Fig. 7, a vertical longitudinal section, the middle part of which is taken in the plane of the line yz in Fig. 3 and the end parts in the plane of the line m n in Fig. 8. Fig. 8 is a top view of the apparatus.

Similar letters refer to similar parts throughout the several views.

The box B, erected on the ground plate A, is filled up with water or some suitable fluid and serves as a cooler. The cold fluid enters' the box at B', and the warmed iiuid leaves it at B2.

Inside the box B is the casing F, having an inlet-piece G, forminga gas-receptacle7 three outlet-pieces M N O, and on both sides annular faces F', Fig. 4, cast on. E As Figs. 1 to 4y Serial No. 541,634. (No model.) l

l show, the casing F has spaces or cavities to allow of the cooling-iiuid flowing through. The annular faces F F have lengthy openings G2 M2 N2 O2, Fig. 4, communicating with the inlet and outlet pieces G M N O, the said openings being set at certain angles (here ninety degrees) to each other. At the casing F is also arranged the piece H, the cavity K of which serves as an igniting-chamber. In each annular face F an opening K2, Figs. 4 and 7, is made, which is at a different distance from the center than the openings G2 M2 N2 O2 and leads into the ignitingphamber K. Into the piece H, Fig. 3, the tap H, with the embedded igniting-wires I I', is introduced.

A suitable arrangement in any of the known manners is provided for, whereby electrical sparks are kept passing over at the ends of the igniting-wires I I in the chamber K. This chamber at the saine time communicates with the outlet-piece O by means of a narrow pipe K', the purpose of which will be explained later on. For draining off any oil or grease that may get into the chamber K the pipe .L is employed.

The box B is provided with suitable bearings O and D'for the shaft T, the one bearing, D, being supported by the stuffing-box E. The shaft T is to be driven from some engine, pulley, gear-wheel, or other source, and its speed should be determined by trials or experiment.

On the shaft T are mounted on both sides of the casing F the two drums P P, which can be shifted lengthwise and are obliged by the feathers T2 T2 to partake in the revolution of the shaft T. They are pressed against the faces F F of the casing F by means of the springs U' U. The several flat pieces of the springs U U are kept together in the center by the locks V V, each secured and pressed forward on the shaft T by two nuts l/V W. The ends of the springs U U are placed between suitable projections P2 P2, Fig. 6, on the drums P P to prevent them from shifting.

Each drum P is provided externally with annular ribs P', Figs. l and 5, to increase thereby its cooling-surface. The drum P is internally divided by the partition-walls P3 P4, Fig. 5, into the two gas-chambers Q R and the two cooling-spaces S S. The latter communicate with the spaces of the casin g F IOO by means of the openings S' S' and with the outside by the openings S2 S2 S8 S3, Figs. l, 2, and G. Thus the cooling-huid is allowed to enter the cooling-spaces S S, during the revolution of the drums P, through the openings S S2 and to leave at those S3. At the face touching the casing F each drum P is provided with openings Q2and R2, leading into the gas chambers Q and R, respectively. These openings Q2 and R2 correspond to those G2 M2N2O2 at the casing F, and are increased by the curved euts Q R', Fig. 5, of such a shape that these correspond more or less to the openings K2, Fig. 4, leading into the igniting-chamber K, as is indicated by the dotted lines in Fig. 4. The two drums P are so placed ou the shaft T that their partitionwalls P P4 are at right angles to each other. Then the openings Q2 R2 of the one drum are at an angle of ninety degrees to those of the other drum, as Figs. l and 2 show.

The apparatus is worked in the following manner: In some compressor of any kind a mixture of combustible gas and air or another explosive mixture is compressed up to a eertain pressure-say three or four atmospheres.

The compressed mixture is then conducted to the apparatus by means of the piping G', Fig. 3, and enters the inlet-piece G. For the sake of clearness only the gas-chamber Q of the left drum P, Fig. l, is now taken into consideration. Vhen during the revolution of the drum P the opening Q2 comes over that G2, Figs. 4t and 5, at the casing F, the gas-chamber Q is filled up with compressed explosive mixture from the inlet-piece G. The drum P, moving on, the communication between the chamber Q and the piece G is intercepted and the curved cut Q of the opening Q2 comes now over the opening K2, Fig. 4. In this moment some of the mixture escapes from the chamber Q into the igniting-chamber K and is there ignited by the electrical sparks, when an explosion will occur. Then the products will have a very high pressure-say ten or fifteen atmospheres. As the drum P is revolving further, the communication between the chamber Q and the igniting-chamber K is soon intercepted and that between the chamber Q and the iirst outlet-piece M established. Then a part of the explosion products will be discharged from the chamber Q into the piece M and the adjoining piping M until the communication is again intercepted. Soon after this the opening Q2 of the drum comes over that N2, Fig. 4, of the casing F, when the other part of the explosion products will be discharged into the second outlet-piece N and the adjoining piping N until the communication between the chamber Q and the piece N is interrupted. Afterward the said opening Q2, Fig. 4, comes over that O2 of the third outlet-piece O, when the rest of the explosion products is exhausted from the chamber Q into that piece O and its piping O. Then the drum again attains its original position, the whole of the described occurrences will be repeated during the following revolution. The same is the case with respect to the other gas-chamber R of the drum P and also to the two chambers Q R of the other drum. Thus during a revolution of the shaft T the compressed explosive mixture is admitted successively into the four drum-chambers and there exploded, whereupon the explosion products are discharged from each chamber, one after the other, so that a nearly uninterrupted supply of highpressure gas is obtained by the main pipe lV and equally a nearly uninterrupted supply of low-pressure gas bythe other main pipe N. To equalize the pressure of these two gas streams, they may be iirst passed through suitable spacious vessels and the like ere they are led off to their destinations. The pressure inside the igniting-chamber K being very highv (ten or fifteen atmospheres) after each explosion requires to be reduced in order to enable some of the compressed mixture (of,

say, three or four atmospheres) from the following drum-chamber to enter the ignitingchamber K. For this reason the above-mentioned narrow pipe K is inserted between the igniting-chamber K and the outlet-piece O to enable the explosion products in the chamber K to at once escape.

Where it is preferred, a clack or other valve may be inserted between the inlet-piece G and the piping G, Fig. 3, to prevent explosion products from entering this piping and mixing with the compressed explosive mixture.

The drums P P are shown with two gaschambers Q R and one opening Q2 or R2 leading to each of same. There it is so preferred, however, the number of the drum-chambers and of the openings leading to them may be altered.

The openings G2 M2 N2 O2 at the casing F are shown to be alike and set at right angles to each other. They may, however, be made of different sizes and therefore set at angles different from ninety degrees. In this manner it is possible to secure, for example, a greater supply of high-pressure gas than that of low-pressure gas, and vice versa. The construction of the cooling-box B maybe altered to suit the ground-plate A, the shaft T, and the joints of the pipes. The narrow pipe K may be provided with a cock or valve to regulate the emission of the explosion products from the igniting-chamber K.
