improved code and apparatus for marine safety signalling." This invention consists of two portions :-the code or system of signals for indicating a vessel's course, and secondly, the apparatus for automatically operating a fog-horn or whistle to give such signals. According to the first part of his invention, the inventor subdivides the horizon or compass card into eight equal parts, and to each part allots a given signal, thus:

N. to N.E.

N.E. to E.

E. to S.E.

S.E. to E.

S. to S.W.

S.W. to W.

W. to N.W.

N.W. to N.

The long dashes representing long sounds of considerable duration, say six seconds, and the short dashes, short sounds, say of three seconds. It will be noticed that all the signals having any east in them begin with a long sound, and all those having any west in them begin with a short sound. All the signals having any north in them end with a short sound, while all those having any south in them end with a long sound. The apparatus for operating the fog-horn, &c., consists mainly of a bellows or equivalent pressuregenerating mechanism, arranged in a frame, and operated by a treadle, lever, or other device. In connection with this mechanism is a plate or disc, perforated or otherwise, and formed with a series of long and short holes, apertures, or operating devices, adapted to control the passage of the air, steam, &c., to the fog-horn or whistle in regulated quantities, so as to regulate the length of the blast or signal given. The signal operating devices are controlled by a pair of cylinders working one within the other, one provided with cam operating surfaces, and the other with cams or cam surfaces, so arranged that they shall act together to cause one-eighth of a revolution of the plate or disc already mentioned. The length of the whole would regulate the length of the blast. A dial is placed at the upper part

of the apparatus, marked with the eight points of the compass already referred to, with the code indicating spaces between. A handle provided with a pointer is applied to the axis of the machine, so as to set it in position to give any required signal. There is also an automatic locking device, so that when set the machine cannot be changed till that signal be given. When using steam, an arm is provided for turning it on and off, and suitable valves are provided for regulating the passage of either air or steam.

2057/79. John Fisher, Southampton Buildings, London. “Improvements in the construction of and in the method of driving screw-propellers." The object of this invention is to lessen the shocks to the machinery occasioned by broken water when first starting, &c. Room is left in the opening in which the screw works to allow of its sliding backwards and forwards for a short distance, and a like arrangement is provided inside the vessel, so that, while continually turning round, the shaft may travel lengthwise as required. Suitable helical or other springs are provided and placed between flanges on the two parts of the shaft where the joint is placed. When starting the screw, and before the vessel has acquired any forward motion, part of the force of the blades striking the water is taken up by the springs; but, when the vessel is in motion, the thrust is always taken by the thrust bearings in the ordinary manner, the shocks being softened by the springs. Should any sudden cause retard the revolution of the screw, or hasten the forward movement of the vessel, the springs will expand and lessen the shock which would otherwise be occasioned.
