Owing to the use of the magnetic stabilizscopes, such as shown in Fig. 3, the idea in matter will be easily understood. The main purpose of the invention is the mechanism for magnetically stabilizing the gyroscopes and by reason of the mounting of the mechanism the gyrosoopesare allowed perfect liberty in revolving within the stabilizing mechanism without the possibility of con tact. In addition alljimpulses acting on the apparatus of rotating masses immediately produce reactionary impulses working from one system to the other by magnetic attraction. .The peculiarity of this invention is the fact that within the same system several gyroscopes are simultaneously arrested from without by magnetic impulses since the rotatingmasseshave the tendency ofevading the impulses falling upon them rectangularly and of thus producing magnetic powers counteracting and annulling the -.primary effect until they have reached again their normal positions. I

Under the four axes in the drawing g hi, i and 1 0 the axis g is distinguished by falling' in with the symmetrical plane of the vertical direction whereupon it may be called the symmetrical axis of the system. The axis h is rectangular to the symmetrical axis 9? while the axes 2' and k again inclosing with the symmetrical axis angles of are situated parallel of the rings of the rotary bodies. The direction of the movements of the gyroscope may be derived from the tendency of the rotating masses slowly to enter with their swinging planes into the directions of impulses applied therefor. The fettering of the system to the axis k is eifected by the rotary body it supported by the magnets a and '0 the fettering to the axis 2' by the rotary body v supported by the magnets b? andd Impulses around the axis it must produce symmetrical 1nove ments while impulses to the axis 9 eflect divergent positions of the g'yroscopes.

One may obtain a new and useful result from the magnetic stabilizing-mechanism represented in Fig. 3 by providing the rotary bodies u and o with a fixed symmetric angular elevationf In consequence thereof from the'rotationgof the two gyroscopes annulling each other within the system until aresulting swing arises, for instance, if p is the angle of elevation and 9 they swing of either gyroscope,

=q /2 sin 10 and inasmuch as the whole system obtains a momentum in the horizontal direction system a resulting plane of rotation in the vertical direction. Secondly, the frame y is fettered in the horizontal plane by gravity and Thirdly, the rotary masses u and '0 are fettered in asettled angle of elevation by gravity or by an elastic or magnetic material.

' Thus it is apparent that the system represented by the frame y in reaction to the rotation of the earth working as a single top revolving on the axis 71 is meridian seeking at any rate in the same manner as it is known from other gyroscopic compasses. I

It is also to be noted that the frame 3 must in each instance be suspended soas to swing with respect to two horizontal axes, the iron ring 7 may be either rigid as by being fixed on a vessel or suspended so as to swing. When the iron ring f is rigid as mentioned there must be a sufliciently great space between the plane of this ring on the one hand and the pole plane of the magnets a, I

6 c and (Z on the other, so that under'certain conditions, for example, heaving twist ing movement of the vessel; the magnetic impulses acting on the frame y areJprevented from taking an undesired, for example, reverse direction. On theother hand, when the iron ring is oscillatably suspended, the space between the two planes mentioned may be less, if the ring is stabilized'by a special gyroscope horizontally. The oscillation may be free with respect to one as well as two horizontal axes. On marine vehicles it is generally suliicient to havethe ring f movable only relatively to the longitudinal axis of the vessel. 7
