Patent GB-131300-A (GB)
IPC: B63B21/30
Abstract: 131,300. Leparmentier, F. A. F. Nov. 22, 1916, [Convention date]. Anchors are constructed with two pairs of flukes united to form a head, the centre of gravity of which is below the axis of the pivot, the head pivoting on the shank in the same manner as in stockless anchors. The upper flukes b are situated in a plane at right-angled to that of the lower flukes a and pivot on the pins c. The flukes are formed in two portions united, as shown, in the plane of the lower flukes. It is stated that by this construction the combined advantages of a pivoted anchor and ordinary stock anchor are obtained. To enable disengagement of the anchor to be made in exceptional circumstances, stops i, held in place by bolts e, are fitted, which ordinarily limit the motion of the shank, but are sheared by excessive stress to permit a more direct pull on the anchor to release the same. Lead may be filled into the hollow space g.

Patent GB-131912-A (GB)
IPC: A63H23/06
Abstract: 131,912. Beck, H. March 16, 1918, [Convention date]. Floating toys. - A toy submarine mine comprises a submerged air-container and means for releasing the air in order to agitate the surrounding water in imitation of an explosion. As shown in Fig. 1, the mine consists of a hollow sphere 10 kept submerged by weights 12 and provided with a valve 11 for the admission of compressed air. An outlet or neck 16 is closed by a lid 15, which is kept firmly in place by a latch 20. A spherical weight 26 having a conical bore 27 slides on an upright 25 secured to the sphere 10, and is provided with a bent wire 28 by which it is supported on the tapered upper end of the post 25. Thus, if the weight 26, or a float 30 attached to the wire 28, is touched by a toy boat, the weight will slide down the post 25 and, striking the arm 23 of the latch 20, will release the lid 15, and the air escaping will represent the explosion of a mine. Instead of the closing-device shown in Fig. 1, the lid 15 may seat on an inwardly projecting neck, the lid being kept closed by the pressure of the air in the sphere. The fall of the weight 26 is then arranged to drive the lid inwards, thus releasing the air. In a modification, the mine consists of two hemispherical sections hinged together and kept closed while in the water by a latch. An upright, when struck by a boat, trips the latch and releases the air. Instead of being a closed shell, the mine may be open at the bottom. In this case, the trapped air is released either by tilting the mine or by the release of a latch which retains a spring-operated lid. The air in the mine may also be compressed by a self-contained air-pump, and the lid may be released by hand, either by pulling a cord, or by means of a pneumatic or flexible release such as is used for operating camera shutters. When the device is used with a small quantity of water contained in a small tank, the body of the mine mav be placed underneath the bottom of the tank, the neck projecting through the bottom into the water. Fig. 12 shows the toy arranged as a torpedo. An elongated body 113 has a rudder 114 at one end, and at the front end a lid and latch similar to those shown in Fig. 1. The propelling-means consists of a tube 124 extending into the body 113. Water 115 contained in the body is expelled through the tube 124 by the compressed air and drives the torpedo. In a modified form, the torpedo is provided with a selfcontained air-pump and with horizontal rudders.
