SPANISH TORPEDO FLEET DESTINED FOR CUBA. IMPROVED CALIPERS. To facilitate the proper aligning of shafts in a line of shafting the calipers shown in the accompanying illustration have been devised and patented by Fred A. Thompson of Eureka Wis. Fig. 1 is a plan view showing the use of the device with the shaft in section the calipers indicating the distance from the center of the shaft to an auxiliary guide line and Fig. 2 is an inverted plan view. The device comprises a main frame provided with angular guide arms the frame having a rest adapted to be seated on the surface of the shaft caliper
SPANISH TORPEDO FLEET DESTINED FOR CUBA. IMPROVED CALIPERS.

Fig. 1 is a plan view showing the use of the device with the shaft in section the calipers indicating the distance from the center of the shaft to an auxiliary guide line and Fig. 2 is an inverted plan view. The device comprises a main frame provided with angular guide arms the frame having a rest adapted to be seated on the surface of the shaft caliper arms being fitted to slide on the an gular guide arms and a block being held to slide on the frame: links connect the block with the caliper arms to bring their points in contact with the surface of the shaft at opposite points and at right angles to a radius at the point of contact of the rest with the shaft. After the desired adjustment is made the several parts are locked in place by screwing up the clamp ing screw. The frame is provided with a graduation not shown reading the diameter of the shaft on which the calipers are placed and is read by a pointer or mark from the guide block to indicate the distance from the center of the shaft to the guide line. 1 1 SPANISH DESTROYERS AND TORPEDO BOATS DESTINED FOR CUBA. We present an illustration which will be of special interest in view of our present critical relations with Spain. It represents several of the destroyers torpedo boats and torpedo gunboats which are destined for service in Cuban waters. The first division which includes the torpedo boat destroyers ' Pluton' ' Terror ' and 'Furor' and the torpedo boats ' Ray' ' Halcon' and ' Azor' is un der the command of Fernando Villaamil. The second division will consist of the torpedo boat destroyers ' Osad' 'A udaz ' and ' Proserpina' (which are about completed by the builders at Glasgow) and the tor pedo boats ' Ariete' ' Habana ' and ' Barcelo.'
