the convoluted spaces or channels formed between said blades and likewise oppositely disposed to the natural or ordinary pitch of the screw, substantially as and for the purposes set forth. (6.) An improved screw propeller consisting of a hub or boss, or a number of bosses in substitution for a single boss, with a rearward conical end, in combination with a series of relatively proportioned blades disposed thereupon in clusters aslant of the axis, and overlapping each other in the convoluted line of sight; the convoluted channels (likewise oppositely disposed to the natural or ordinary pitch of the screw) formed between the lines of overlapping blades, the rearward blades forming a standard for proportioning the diminished blades, and the front and rear blades whose predetermined maximum and minimum diameters are used to determine the proportionate areas of the associated intermediate blades, substantially as and for the purposes set forth.

No. 22316.—15th January, 1907.—GODFREY BENINGTON JOHNSON, of 8 Victoria Street, Westminster, England, Engineer. Improvements in machinery for corrugating metal sheets.

Claims.—(1.) In a machine for corrugating sheet metal, comprising pairs of rolls each consisting of an arbor having splined upon it a number of roll-sections normally held apart by spring pressure, the employment, for determining the normal distance apart of said sections in a roll, of stops slidable upon the arbor, and leading-screws journaled in bearings carried by the arbor, successive portions of the length of each leading-screw having threads of progressively varying pitch which engage in threaded apertures in the respective stops, so that by the rotation of the screw the positions of all the stops wherewith it engages may be simultaneously adjusted, substantially as described. (2.) In apparatus constructed substantially as specified in claim 1, making the successive portions of each leading-screw, which have threads of progressively varying pitch, of progressively diminishing diameter, counting from either end of the roll, substantially as and for the purpose set forth. (3.) In apparatus constructed substantially as specified in claim 1, providing each roll with independent leading-screws extending in opposite directions from a point in the length of the roll, and adapted to enable the stops with which said screws respectively engage to be adjusted independently and in opposite directions, substantially as described.

No. 22332.—23rd January, 1907.—FERDINAND GEORGE PHILPOTT, of Lindenow, Victoria, Australia, Carpenter. Improvements in washboards or attachments thereto.

Claims.—(1.) In a washboard rubbing-surface, a soap-well. (2.) In a washboard, a soap-well having a resilient base on which to place the soap. (3.) Means to support yieldingly a base for soap in a well in or attachable to a washboard. (4.) Means to adjust or vary the normal height of a base for supporting soap in a well in or attachable to a washboard. (5.) A soap-well located adjoining a washboard rubbing-surface so that clothes may become soaped during the rubbing thereof. (6.) As an attachment for washboards, a receptacle for soap, in combination with spring means outside thereof adapted to press the said receptacle against the rubbing-surface of the washboard. (7.) A washboard-well having means to support soap yieldingly, and means to adjust the normal height of the soap-support. (8.) In combination, a washboard rubbing-surface, a well, a soap-support therein, one or more springs under the support, a pillar under the support, and means to raise or lower the pillar at will. (9.) A washboard-well for soap, a screw-threaded pillar beneath a soap-support therein, a spring or springs under the said support, an aperture in the well through which the pillar projects, and a nut or the like engaging the said pillar. (10.) In combination with a washboard, a well having a base to support soap, means to raise the base, and a slot in the well-side to allow said means room to act. (11.) The combination of the parts illustrated in Fig. 2, as a soaping-device for washboards, substantially as described. (12.) The combination of the parts illustrated in Fig. 3, as a soaping-device for washboards, substantially as described. (13.) The combination of the parts illustrated in Fig. 4, as a soaping-device for washboards, substantially as described. (14.) The combination of the parts illustrated in Fig. 7, as a laterally movable soaping-device for washboards.

No. 22335.—23rd January, 1907.—JOHN WILFRED DALTON, of Sandwich, Barnstaple, Massachusetts, United States of America, Mechanic. Improvements in breeches buoys.

Claims.—(1.) A breeches buoy having means of signalling operated as a result of the person occupying the buoy, substantially as described. (2.) In connection with claim 1, the pull for operating the signal, said pull being operated by the weight of the persons in occupying the breeches, substantially as described. (3.) In connection with a breeches buoy, means for displaying a signal light operated automatically when the breeches are occupied, substantially as described. (4.) In connection with a life-saving buoy and its traveller-block, a cushion suspended by the lanyards over the head of the occupant of the buoy and beneath the traveller-block, substantially as described. (5.) In connection with the life-saving buoy, a cushion in the form of a buoy arranged over the occupant’s head to protect him from injury from the traveller-block, substantially as described. (6.) A breeches buoy having a rigid means for supporting the traveller-block from beneath, substantially as described. (7.) In connection with a breeches buoy and its traveller-block, a cushioning-device supported by the lanyards and the rigid supports for the traveller-block between the cushioning-device and the traveller-block, said cushioning-device preferably being buoyant, substantially as described. (8.) In connection with the features of claim 6, making the supports for the traveller-block tubular and placing them upon the lanyards, substantially as described. (9.) In a breeches buoy, the signal-box, the traveller, the lanyards, and the spreader for the lanyards adjacent the signal-box, substantially as described.

No. 22336.—23rd January 1907.—WILLIAM ERNEST HUGHES, of Queen’s Chambers, Wellington, New Zealand, Registered Patent Agent (nominee of Fred Starr, Mechanic, a citizen of the United States, residing at No. 1581, 11th Avenue, San Francisco, California, United States of America). Wave motors.

Extract from Specification.—In constructing such motors it is desirable that the float, to be effective, should be of large area and considerable tonnage. But during a storm, when the power and force of the waves are very great, the float is liable to damage itself. Such liability to damage can be prevented by changing the position of the float so that it is no longer exposed to the direct action or full force of the waves. This can be done by raising it above them or sinking it below them; but owing to the weight of the float it is better to submerge it. I therefore prefer to either wholly or partially sink or submerge it, which I do by increasing its weight. It can be constructed as a hollow barge adapted to receive water ballast. As the wave-agitation is superficial and quickly decreases downwardly, it is evident that by sinking the float to a greater or less extent the force of the waves may be utilised to the desired extent without the danger of damage, as above indicated, or by sinking the float to the bottom it will remain substantially stationary.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 22337.—23rd January, 1907.—ADOLPHUS SYDNEY FRANCIS, of 155, Farrington Road, London, England, Engineer. Improvements in gas-lamps for inverted incandescent burners.

Claims.—(1.) An inverted incandescent gas-lamp comprising a gas-supply pipe, a flared or trumpet-shaped chimney, a number of vertical holes arranged in the sides of such chimney, and a number of straight or approximately vertically arranged inverted Bunsen burners passing through said holes in such manner that the points of the burners, where the mantles are mounted, are within the circumference of the trumpet-shaped chimney and the mixing-chambers of said burners are outside of the chimney, substantially as described. (2.) The constructions of inverted incandescent lamps as described, or shown on the drawings.
