No. 15784.—18th December, 1902.—COOLEY DEVELOPMENT COMPANY, a corporation organized under the laws of the State of Maine, and doing business at 83, Braintree Street, Boston, Suffolk, State of Massachusetts, United States of America (assignee of John Francis Cooley, of 667, Cambridge Street, Boston aforesaid, Mechanical Engineer). Improvements in and relating to rotary fluid engines.

Extract from Specification.—The essence of this invention lies in the correlative construction and functional operation of a slowly rotating cylindrical equiradially partitioned abutment element, whose divisional limitations bear upon a like directionally faster-rotating cylindrical cam-surface-piston element, the curves of which they describe in their movement around their common axis set eccentrically to the axis of rotation of the cam-surface element, when caused to move at correlative speed-rates that reckon in complete revolutions of both elements differ by unity, and the number of bearing-points of the one are to the number of cam-rises of the other as the converse of their speed-rates.

[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the specification is inserted instead.]

No. 15785.—18th December, 1902.—JAMES PALMER CAMPBELL, of Wellington, New Zealand, Solicitor (nominee of Harve Reed Stuart, of 524, Wallace Avenue, Pittsburg, Pennsylvania, United States of America, Electrical Engineer). Improvements in controllers for electric motors.

Claims.—(1.) A controller for varying the electro-motive force supplied to polyphase electric motors in which a single resistance for each phase of current is cut in before each successive change in the circuit connections, and cut out directly after each such change, substantially as described. (2.) For varying the electro-motive force supplied to polyphase electric motors through auto-transformers, a controller of the drum type, having sets of fingers and cooperating movable contact fingers so arranged as to gradually vary the lengths of the secondary portions of the auto-transformer windings and connect a resistance in the circuit of each phase of current as each variation in length is effected, substantially as described. (3.) For polyphase electric motors, a controller constructed substantially as described with reference to the drawings.

No. 15786.—18th December, 1902.—JAMES PALMER CAMPBELL, of Wellington, New Zealand, Solicitor (nominee of Hugo Bremer, of Neheim-on-the-Ruhr, Westphalia, Germany, Manufacturer). Improvements in or relating to electric arc lamps.

Claims.—(1.) An arc lamp having downwardly pointing electrodes arranged to be fed forward through the same distance, and provided with masses of metal in proximity to the points of the carbon or metal sleeves surrounding said points, substantially as and for the purpose specified. (2.) An arc lamp having downwardly pointing electrodes, and provided with both downward and horizontal feed mechanism so arranged that a certain amount of operating of the horizontal feed mechanism takes place before the downward feed mechanism is permitted to operate. (3.) The combination with an enclosed arc lamp of a depositing-chamber, connected with the arc-enclosing globe in such a manner that a circulation of the vapours of combustion takes place from the arc-enclosing chamber through the depositing-chamber and back to the arc-enclosing chamber again, for the purpose specified. (4.) Arc lamps having either inclined or aligned electrodes, and provided with regulating mechanism constructed and operating substantially as described with reference to any of the forms shown in Figs. 1 to 9 of the drawings. (5.) An arc lamp having downwardly pointing electrodes inclined to each other, said electrodes being formed with a cross-section, substantially as described with reference to Figs. 10 and 11 of the drawings.

No. 15790.—16th December, 1902.—WILLIAM LOUIS IWAN and JOHN HENRY IWAN, of Streator, Illinois, United States of America, Manufacturers of Earth-augers. Improvements in earth-augers.

Claims.—(1.) In an earth-auger, the combination of suitable permanent blades and a removable blade-section serving when employed to close a portion of the space between adjacent edges of the permanent blades. (2.) In an earth-auger, the combination of a handle, longitudinally concavo-convex blades attached thereto, and longitudinally concavo-convex blade-sections removably connected with said blades and closing a portion of the space between their edges. (3.) In an earth-auger, the combination of suitable permanent blades, and blade-sections adjustably and removably connected with said blades and serving when employed to close a portion of the spaces between the edges of the permanent blades. (4.) In an earth-auger, the combination of a handle, longitudinally concavo-convex blades attached thereto and provided with vertical cutting-edges, downwardly projecting incurved bits and sharply curved inwardly projecting bits, and longitudinally concavo-convex blade-sections removably connected with the blunt vertical edge-portions of the blades. (5.) In an earth-auger, the combination of a handle, longitudinally concavo-convex blades attached thereto and provided with vertical cutting-edges, downwardly projecting incurved bits and sharply curved inwardly projecting bits, and a downwardly extending auger-point carried by said last-named bits. (6.) In an earth-auger, the combination of a handle, longitudinally concavo-convex blades attached thereto and provided with vertical cutting edges, downwardly projecting incurved bits, and sharply curved inwardly projecting bits having overlapping end-portions, and an auger-point with an attaching head bearing on the inner surfaces of said last-named bits and secured to said bits. (7.) In an earth-auger, the combination of a suitable boring-head, a handle-stem bearing the same, handle-bars with a vertical perforation receiving said stem, and means for securing the handle-bars adjustably on said stem. (8.) An earth-auger having concavo-convex blades provided at their lower portions with downwardly projecting inwardly curved bits and abruptly curved inwardly projecting, overlapping, and mutually supporting bits, for the purpose set forth. (9.) An earth-auger having concavo-convex blades terminating in downwardly projecting inwardly curved bits, and having abruptly curved inwardly projecting, overlapping, and interlocking bits, for the purpose set forth.
