Abstract: 16,673. Medveczky, S. von. July 28. Self-driving engines.-Relates to machinery for the production of motive power, and the object is to utilize as useful work that energy which it is stated can be produced by a mechanical arrangement consisting of several parts which may touch, intersect, or penetrate one another. The alterations in the relative positions of these parts may be produced by external force, while they are placed in an enclosed pressure chamber so that a portion of the useful or positive pressure produced during these changes may be liberated by compensating or eliminating a portion of the resisting or negative pressure ; the positive pressure is stored in the moving parts of the engine. The invention consists in creating such dynamical conditions in any enclosed pressure chamber that, from the opposing pressures produced, a portion of the resisting or negative pressure is rendered latent mechanically. The liberated positive pressure causes an increase in the volume of the moving parts of the engine, which produces an increased pressure in the enclosed pressure chamber, and therefore generates potential energy. Fig. 1 shows a sectional view of the engine, and Fig. 2 a sectional plan through the centre of the compensatory part M N, L J, and K I. The engine consists of (a) two boxes A B C D E F G B, and a b c d e f g h, formed with flexible sides, (b) three so-called "compensatory pieces" M N, L J, K I, and (c) six so-called "potential "energy pieces " P1, P2, P3, P4, P5 P6, The engine is placed in the pressure chamber, which is a tank made in two parts separated by the partition 1 and filled with water. The partition 1 is provided with openings 2 having covers 3, and the lower tank has a floor 4. The engine may be rotated by the axle 9, and the sides E H, F G, e h, f g can turn about the axles 5, 6, and the sides E F, H G, e f, h g can turn about the axles 7, 8, respectively ; these axles 5, 6, 7, 8 can change their positions. The ends J, I of the compensatory parts L J, K I are connected by a rod 10. The parts P1, Pz are constructed to expand and contract telescopically. All the parts marked P must be able to slide in and out of the pressure chamber, and they must be able, when pushed back, to fix themselves automatically, as by means of the fixing-rod 14. The pieces L J, K I are hollow or solid, and the interior of the piece M N, as well as of the pieces P1, P2, are filled with air which communicates with the atmosphere. The other parts of the machinery, especially the spaces V1, V2, V3, are filled with water or other fluid under pressure, and communicate with the pressure chamber by means of pipes 25. Power is transmitted from the sides of the boxes to the cords of the balance weights Q1, Q2, Q3, by providing each box with spur-wheels 16,17 fixed on the pipes 18 which are fixed to the shaft 9 ; these pipes are provided with pulleys 19, 20 on which the cords are wound. The balance weight Q1 is provided to overcome the negative pressures produced by the movements of the engines when the weight descends. The weights Q2, Q3 are for storing the positive pressures that come into operation during these movements, and the weight Q3 is used for taking up the positive pressures liberated by the compensation of the negative pressures. The working of the engine is effected by starting it by a primer-mover and allowing four successive changes in the relative positions of the various parts of the engine to take place. Figs. 8-11 show the four changes, and in each case the previous position is indicated. The resisting or negative pressures are indicated in the Figures by lines sloping downwards from left to right, and the useful or positive pressures by lines sloping upwards from left to right. For the compensatory parts, the negative pressures are shown by vertical lines and the positive pressures by horizontal, and the positive pressures acting on the P pieces are shown by lines at right-angles to the axes of these parts. Figs. 8-11 show the movements of the parts and the distribution of the energy called into play. By calculation embodied in the Specification, a result is arrived at which is said to indicate the existence of a so-called " libera- " tive positive pressure." It is stated that when the parts P are arranged in such a manner as not to go back into the boxes again, but new pieces P are continually introduced into the pressure space, the engine may be used direct for raising water or other liquids or for compressing steam, gas, or air.
