No. 17917.—18th May, 1904.—HALL SIGNAL COMPANY, a corporation organized and existing under the laws of the State of Maine, United States of America, and having its principal place of business in New York City, United States of America (assignees of Clarence William Coleman, of Westfield, New Jersey, United States of America, Engineer). Improvements in signal apparatus.

Extract from Specification.—The invention seeks to provide an apparatus characterized by simplicity of construction and efficiency and reliability of operation. In carrying out this purpose it employs fluid-pressure for operating the signal. It is more particularly proposed, however, to employ liquefied gas stored in a local reservoir in proximity to the signal, which, when released, assumes the gaseous form for performing the required work. It is also proposed, in carrying out the invention, to employ a device interposed in the mechanical connection between the signal and the motor whereby the efficiency of the motor will be increased when the signal is moved from one position to another. The invention also proposes to provide a suitable system of electric circuits for controlling the operation of the signals. In the present embodiment of the invention hereinafter set forth the signals are arranged to stand normally at “Danger,” home and distant signals being carried on the same post. The signals may, however, be arranged to stand normally at “Safety” if desired. The invention, however, is not in all of its features limited to such details. Moreover, the signals have in their best form a normal bias to “Danger” position, and when moved from “Danger” to “Safety” position are held from return movement by a retaining-device until released.

No. 17930.—16th May, 1904.—JOHN JAMISON, of Dunedin, New Zealand, Inventor. Improved aerial reading-desk and table apparatus.

Extract from Specification.—I provide a swinging arm, somewhat like a crane on a small scale, and attach various conveniences, either fixed or capable of being moved, removed, or placed in convenient positions as needed from time to time, to one or other part of the apparatus, with balance-weights where needed to keep the required strain on the cords or suchlike for effecting the movements to be described.

No. 17943.—23rd May, 1904.—EVA HOOPER, of Dunedin, New Zealand, School-teacher. An easel attachment to school desks.

Claim.—An attachment for school desks consisting of a frame of wire formed with spring clips on its bottom end which are adapted to pass on to and grip the back rail of the desk and hold the frame in an upright position, substantially as specified.
(Specification, 1s. 3d.; drawing, 1s.)

No. 17945.—25th May, 1904.—GEORGE JOSEPH CARTWRIGHT, of Bailey Street, New Farm, Brisbane, Queensland, Australia, Engineer. Smoke-consumer and fuel-economizer.

Claims.—(1.) In steam-boiler furnaces, the admission of regulated quantities of heated air into the furnace and of cool or partly heated air into the combustion-chamber by means of passages in the fire-bridge, as described and illustrated. (2.) In steam-boiler furnaces, the firing of unconsumed gases in the combustion-chamber by means of a fire-tube, as described and illustrated. (3.) In steam-boiler furnaces, the combination and arrangement of parts for promoting combustion and preventing smoke, substantially as described, explained, and illustrated.
(Specification, 2s. 9d.; drawing, 1s.)

No. 17946.—25th May, 1904.—The Honourable CHARLES ALGERNON PARSONS and GEORGE GERALD STONEY, both of Heaton Works, Newcastle-on-Tyne, Northumberland, England, Engineers. Improvements relating to dynamo-electric machines.

Extract from Specification.—Our invention consists in obtaining, in a continuous-current dynamo-electric machines, by means of suitably disposed and proportioned fixed windings, (1) a practically fixed line of commutation at all loads without sparking; (2) an increase in the allowable ampere-turns per inch diameter of the armature, so that an increase of output of at least two or three times may be obtained from a machine of given size. Our invention further consists in devices and arrangements for providing for the ready removal of the armature when required.

No. 17947.—25th May, 1904.—JAMES PALMER CAMPBELL, of 15, Featherston Street, Wellington, New Zealand, Solicitor (nominee of Lawrence August Merkt, of Westinghouse Building, 2, Norfolk Street, Strand, London, England, Mechanical Engineer). Improvements in mixing-valves for explosive engines.

Claim.—A mixing-valve for explosion engines, with or without a separate admission-valve, constructed and operating substantially as described with reference to the drawings.
(Specification, 3s. 3d.; drawing, 1s.)

No. 17948.—25th May, 1904.—AKTIEBOLAGET SVEASEPARATORN, of Hamngatan 5B, Stockholm, Sweden, a stock company (assignees of Algot Levin Christenson, of Sturegatan 13, Stockholm aforesaid, Director). Improved inlet-pipe for centrifugal separators.

Claim.—In such inlet-pipes for milk centrifugal separators, or the like, the outlet-openings of which have the shape of holes or slots extending throughout the whole length of the inlet-pipe or part thereof, the arrangement that the size of the said outlet-openings decreases towards the lower end of the inlet-pipe in order to counteract the tendency due to the force of gravity of the full milk introduced to flow out from the inlet-pipe chiefly at the lower part of the latter and thereby to effect a more uniform distribution of the full milk over the whole liner than heretofore.
(Specification, 2s.; drawing, 1s.)

No. 17949.—25th May, 1904.—CHARLES FREDERICK JAEHN, Mechanic, and WALTER EMLING, Trustee, both of 2700, South Eighteenth Street, St. Louis, Missouri, United States of America. Improvements in driving-gear for pulleys.

Extract from Specification.—The object of our invention is to interpose, between a drive-shaft and its pulley, gear mechanism by which it may be possible to impart to the pulley a motion of rotation either contrary to that of the shaft, so that the necessity of cross-belts shall be dispensed with where it is desirable to impart from said pulley motion to a countershaft in such reverse direction, or to impart a motion in the same direction with the shaft when desirable. A further object is to provide means for disengaging the pulley from said shaft, converting the same for the time being into a loose pulley, and bringing the countershaft to a standstill.

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

No. 17950.—25th May, 1904.—SEYMOUR WENTWORTH BONSALL, of 315, West Fifteenth Street, City, County, and State of New York, United States of America, Manufacturer. Improvements in wardrobes.

Extract from Specification.—The present application has relation to certain forms of wardrobe-equipment whereby garments which are suspended in a closet or wardrobe may be easily drawn forward into view without the use of sliding apparatus of any kind. The invention is particularly adapted to closets of relatively small height and of considerable width in proportion to their depth. In closets of this kind it is often extremely inconvenient to lean down in order to see the garments and pick out the one desired, and by the use of this invention the entire group of garments may be drawn forward into view, where any one is available without disturbing the others, the garments being preferably suspended flatwise and in contact one with the other, with the planes in which they lie at right angles to the front of the closet.

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