F¹ in Fig. 5 The lower or downward curve is then slipped over the upper or upward curve in such a manner that a hinged joint is formed. A sufficient number of laths are joined together in this manner to provide the length required for the shutter. The spindle I is passed through the hollow tube formed by the curves and riveted to the inner and upward curve of the lath. The links G are provided to carry the weight of the shutter and prevent strain being applied to the curves of the laths, which would be liable to straighten out if such support were not provided. These links work freely upon the spindle I between the ends of the laths K and the rollers E. The mechanism for raising or lowering the shutter consists of the lifting-wheel W, having upon its periphery indentations R which engage the ends of the spindles I shown at O, Fig. 2. As the wheel W revolves the indentations R engage the spindles and lift them one by one and pass the shutter along the guides provided for the purpose, namely, the grooves or channels D in the rafter A along which the rollers E travel. The endless sprocket chain L conveys the power applied by any suitable device to the sprocket wheel M attached to or forming a part of the lifting-wheel W. A suitable device for applying or providing the power to lift the shutter is a bevel gearing operated by a crank. The act of raising the shutter causes it to assume the function of a verandah-roof. Reversing the action reverses the position and turns the verandah-roof into a window-shutter. If desired the verandah may be half-roofed and the upper part of the window covered at the same time.

Claim.—The combination of the several parts and devices described in this specification, the whole forming a combined verandah-roof, window-shutter, and sunshade, substantially as described and illustrated.

No. 14160.—24th October, 1901.—EDWIN PHILLIPS, of 533, Collins Street, Melbourne, Victoria, Australia, Certified Patent Agent (nominee of Everard Steele, residing at Mill Valley, Marin, California, United States of America, Manufacturer of Explosives). Explosives, and the methods of making the same.

Claims.—(1.) An explosive consisting of a mechanical mixture of nitrated phthalic acid and an oxidizing agent, substantially as described. (2.) An explosive comprising nitrated phthalic acid and chlorate of potash, substantially in the proportions specified. (3.) An explosive consisting of grains each of which comprise a main-body portion and a complete coating, said body portion consisting exclusively of chlorate of potash and said coating consisting exclusively of an ingredient reacting explosively with the chlorate of potash, said ingredient being insoluble in water but soluble in a volatile liquid, whereby the grains of chlorate of potash are entirely protected from the action of moisture by a hardened coating of the ingredient, substantially as described. (4.) An explosive consisting of grains each of which comprises a body portion consisting exclusively of an oxidizing agent, and a complete coating consisting exclusively of an ingredient reacting explosively with the oxidizing agent, and insoluble in water but soluble in a volatile liquid, so forming a hardened coating around the grains of the oxidizing agent, substantially as described. (5.) An explosive consisting of grains each comprising a body portion and a complete coating, the body portion consisting exclusively of one ingredient and the coating exclusively of the other ingredient, said ingredients reacting chemically with violence, the latter being insoluble in water but soluble in a volatile liquid, substantially as described. (6.) A process of making an explosive, consisting of two ingredients which react chemically with violence, one of said ingredients being a substance insoluble in water but soluble in a volatile liquid, which consists in forming the other ingredient into grains or small particles, dissolving in a volatile liquid the ingredient which is insoluble in water, coating the particles of the other ingredient with the latter ingredient so dissolved, and then evaporating the volatile liquid to leave a hardened coating of the latter ingredient on the other ingredient, substantially as described.
