TO (1127/ wi'mm it may concern:

Be it known that I, ISIDOR KITSEE, of the city and countyof Philadelphiafitate of Pennsylvania, have invci ted certain new and usefullmprovementsin VirelessorSpaceTeleg- Buoys, as is well known, are placed at loca-, trons which are considered dangerous for'sea-' going. vessels, and it has been the aim to provide such buoys with devices with the aid of which their presence should be'knownto ves sels passing nearby, so that they may beable to avoid the danger. heknowledge of the location of these buoys is of the greatest 2o importance for vessels in foggy or stormy weather, and so far no device is in existence capable of warning the passing vessels of their presence. To produce such a device is the aim of inyinvention. Referring to the drawings, Figure 1 is a side elevation of the buoy; Fig. 2, a diagrammatic view showing the electrical connection of my device partially inclosed in and partially out of the buoy.

A is the buoy p oper; B, the mast secured to the buoy, having secured thereto the sphere b.

O is a tube secured to thebottom of the buoy, provided with the anchor-cable eye 0. D is a carbon plate; E, a zinc plate. Connected to the carbon plate D through the wire 5 is one te'rminalbf the electrolytic interrupter consisting of the platinum Wire II, provided with the insulation 1 and the con- 40 ducting-tube C. The other terminal of the I interrupter is connectedthrough the wire 6 with the brush j, which brush is in electrical connectionwith the drum 5, the periphery of which consists of metallic points alternating with insulated spaces. On this drum rests the brush j, connected through wire 3 with the primar P of an inductorium. The other terminal 0 the primary is connected through wire ewith the zinc plate E. In proximity .to the primary P is the secondary S, one terminal of which is connected through wire 2 with the ground or watcrG, the other terminal through wire 1 with the aerial conductor 1). The plates DE fulfil the office of electrodes of a voltaic cell, and-tho salt water of the ocean or seafnlfils the ofiice of the electrolyte of such cell. If a carbon plate and a zinc plate are immersed in sea-water,the voltage developed is about one and five-tenths, and each square inch exposed will give, ifthc 6o two-plates are not too far apart, aboutthreeeighths of one'ampere, and as the water of the sea is always in motion polarization will be obviated. The working of the electrolytic interrupter is to-day so well: known that it does not need further explanation.

The plates D E are secured to the buoy in such manner that the greatest part of these plates is exposed to the waves of the ocean, and the electrolytic interrupter is also to its greatest part im mersed in the water, and,with the exception of the aerial conductor, all other parts are inclosed in the buoy. Through the immersion of the zinc and carbon plates an electric current is generated. This current passes through the primary coil, wire 3, brush 7, metallic contact-point of the drum J, brush 3'', wire 6, electrode H of the electrolytic interrupter, through the water to electrode O, and through wire?) and plate D and water as an electrolyte back to the plate E,

The drum- J may be actuated by any of the well-known means,either niechanicahthrongh a clockwork, or electricalwith the aid of a motor. On. the periphery of the drum are, as stated before, conducting contact points. They are grouped in such manner as to .represent the prearranged number which should correspond to the numberof the buoy placed on the chart. It is understood that the contact-points are ll electrical connection with the conducting-drum.

The working of the device is as follows: The genera ed-straight current is made an interrupted one with the aidof the electrolytic interrupter and will therefore induce impulses in the secondary. Theseimpulses, if of high enough potential, will, with the aid of the aerial conductor, be transmitted to obj jects, such as vessels, and translated into sound or record if these vessels are provided with a suitable receiver for these current .im

pulses or waves but these interrupted or re-' curring impulses can only flow to the primary it both of the brushes jj are in electrical contact with each other, and as this electrical contact is only possible when-the brush j strikes one of the contact-points on the periphery of the drum it-is obvious that the transmitted electric impulses will be in accordance with the grouping of these contact-points, and as these contact-points represent the number of the buoy it is obvious that the transmitted electric i-mpulses'when translated into sound, glow, or record will 'intheir grou ping also represent the number of the buoy from which the-impulses are transmitted. I

I have in the drawings illustrated the device t as being providedwith-bne voltaic couple im mersed in the sea-waterlo'generate the necessarycurrent; butif itis' found that the potential of the current is too low for practical purposes other voltaic cells, primary or secondar maybe substituted for'thevc0uple,'as described. Ihave also illustrated in thedrawin gs an electrolytic interrupter; but any other of the well-known mechanical or electromagnetic devices may be substituted.- So, for inrstance,ican the terminals of the wires or 6,

. no'w'connected to the electrolytic interrupter,

be connected to brushes of a mechanical interrupter revolving on the same shaft as the.

drum J revolves. l v I Having now described my inventiomwhat "I claim asnew, and desire to secure by Letters. Pate t 1 t to 1 1.
