(2.) In a sealing-lock, the described method of constructing the front plate by bending it so as to form a cavity in front of the lock adapted to retain a sealing-card. (3.) In a sealing-lock, the described method of forming the ticket-cavity substantially as described with reference to Figs. 10, 11, and 12. (4.) In combination with a lock of the kind specified, the use of a hasp shaped so as to fill the mouth of the lock and prevent midway and sideway movement by the box-lid when locked, substantially as described and shown.

No. 17449.—8th January, 1904.—THOMAS WALTER BARBER, of 5, Palmer Street, Westminster, London, England, Engineer. Improvement in speed gear.

Extract from Specification.—According to the invention the driven shaft or member is situated in axial line with the driving-shaft, and in carrying it into practice a variable-throw eccentric is mounted on or connected with the driving-shaft, and surrounding it is a strap carrying engaging-devices adapted to coact with a disc or member which is mounted on a shaft or otherwise suitably and constitutes the prime member to be driven. Means are provided by which rotation of the strap is prevented, so that the movement imparted to it by the eccentric reciprocates the engaging-devices upon that portion of the driven member with which they are in contact and thus causes them to alternately engage and release the member. In this way continuous movement is imparted to the driven member in one direction, and by varying the throw of the eccentric the amount of movement communicated at each operation of the engaging-devices may be increased or decreased for varying the speed. The direction of rotation of the driven shaft may be reversed by mounting the driven member free on the shaft and interposing gearing between it and a sleeve mounted concentrically with the shaft, so that by means of a suitable clutch the driven shaft may be connected either to the driven member direct or to the sleeve with the gearing interposed. In place of preventing the strap of the eccentric from rotating, a second set of engaging-devices may be provided, operating in the reverse direction to those which engage the driven member and adapted to engage a stationary member, so that the strap is made to rotate in the same direction as the driven member and thus increase the amount of movement imparted thereto. The throw of the eccentric may be adjusted in various ways. According to one, the eccentric is provided with a slot which receives one end of the driving-shaft, and links pivotally connect the eccentric with this end of the shaft. Means are provided for moving the pivotal point axially of the shaft, and the eccentric, being suitably prevented from moving endwise, is thrown out further from, or drawn towards, the centre of the shaft by the connecting-links according to the direction in which the pivot is moved.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 17451.—11th January, 1904.—CHRISTOPHE SOULAS, of Jerusalem, Wanganui, Wellington, New Zealand, Priest. An improved swing bed for use on board ship.

Claims.—(1.) For the purpose indicated, in combination, an inner frame with means for supporting a mattress thereon, an outer frame, trunnion-bearings by which said inner frame is mounted in the outer frame, trunnion-bearings by which the outer frame is carried in fixed supports, and a balance-weight dependent from the inner frame, as specified and illustrated. (2.) For the purpose indicated, in combination, an inner frame with means for supporting a mattress thereon, an outer frame, trunnion-bearings by which said inner frame is mounted in the outer frame, trunnion-bearings by which the outer frame is carried in fixed supports, pillars extending vertically from the inner frame, a rectangular frame carried thereby, screens composed of slats supported by said rectangular frame and means for raising and lowering said screens, as specified and illustrated. (3.) A swing bed for use on board ship, consisting of the parts arranged, combined, and operating substantially as and for the purposes specified, and illustrated in the drawing.

No. 17454.—12th January, 1904.—ARTHUR LIDDON WATKINS, of 5, Cannon Place, Hampstead, London, England, Manufacturer. Improvements in grooving or necking metal tubes for the manufacture of paint-brushes, and for other purposes.

Claims.—(1.) The method of grooving or necking metal tubes or ferrules consisting in filling the said tube or ferrule with an elastic material, such as soft wood or bristles, and in then forcing the tube so filled through a die, the bore of which is of the external diameter of the tube and is provided with an internal bead or projection, substantially as described. (2.) The method of attaching the bristles to the handles of brushes by a metal ferrule, in which the bristles are fastened by means of a groove or neck formed in the ferrule by forcing the same through a die having an internal bead or projection, substantially as described. (3.) The method of attaching a ferrule to a handle by forcing the ferrule and handle through a die having an internal bead or projection, substantially as described. (4.) Tubes and ferrules grooved or necked, substantially as described. (5.) Paint and other brushes and similar articles made substantially as described, and illustrated in the drawing.

No. 17455.—12th January, 1904.—WILLIAM LLOYD GALE, of 735, Second Street, Louisville, Jefferson, Kentucky, United States of America, Grocerman. Improvements in smoke-conveyers.

Claims.—(1.) A smoke-conveyer tube for railway-trains, comprising a series of adjustable sections, each comprising a plurality of telescopic members, springs tending to separate said members, and means for drawing the members together to contract the tube. (2.) A smoke-conductor for railway-trains, comprising a plurality of sections independently pivoted on the roof of each car, each of such sections comprising a plurality of yieldably connected telescopic tubular members. (3.) A smoke-conductor for railway-trains, comprising a reversible pivotally mounted section mounted centrally on each car, independent sections pivotally mounted near the ends of each car, all of such sections being reversible and each comprising a plurality of tubular members having yielding connections.
