[No. 33

placement of the centre of gravity of a body carrying a gyrostat or gyrostats or both by forces one of which is a function of the displacement of the gyrostat from the central position, while the other force is a function of the velocity of the precessional movement with or without a third force, substantially proportional to solid friction.

The invention also consists in providing means whereby the precession of the gyrostat or gyrostats can be accelerated, so arranged that the commencement of acceleration can take place before the gyrostat arrives at the central position on its return thereto, after having been disturbed.

The invention further consists in providing means for retarding the motion of the gyrostat or gyrostats, on its or their return back to the central position, when the acceleration has ceased such retardation being arranged to cease before the gyrostat gets back to the central position.

The invention also consists in arranging the retarding and acceleration devices in such a way that a tilting force being brought to bear on the vehicle or body, whatever may be the relative positions of the gyrostat and vehicle, the proper acceleration or retardation for restoring the equilibrium will be brought into play.

The invention further consists in maintaining a continuous flow of lubricant over the bearing-surfaces of a gyrostat-bearing by adapting means on a portion of the shaft adjacent to the journal to effect a circulation of the lubricant.

The invention also consists in arranging on a portion of the shaft adjacent to the journal a pair of rings of triangular section adapted to rotate at different speeds in order to circulate the lubricant by centrifugal action.

The invention further consists in means whereby any lubricant escaping from the bearing is collected in a reservoir having means so arranged that a transference of the collected lubricant to the main reservoir can be periodically effected by the agency of atmospheric pressure and/or periodically or continuously by pumps, hand, or power driven.

The invention also consists in the improved system of lubricating and apparatus therefor hereinafter indicated.

The invention also consists in a vehicle, the body of which is supported at two points disposed respectively at suitable intermediate points at corresponding equalizing or distributing frames or levers, the ends of each of these frames being supported at intermediate points of certain sub-frames, this system being repeated if desirable while the last set of frames are provided with suitable bearings for the vehicle-wheels.

The invention further consists in an arrangement of under-carriages, substantially as indicated in the preceding paragraph, and having at each end all of the points of support-connections such as to permit relative motion between the parts in planes mutually at right angles to one another.

The invention also consists in an arrangement of under-carriages, substantially as indicated in the two preceding paragraphs, and having axle-boxes so constructed and mounted that they are free to move vertically in the horn plates and are free to swivel in a plane perpendicular to the rail.

The invention further consists in an arrangement of braking devices for use with the under-carriages of single-track vehicles, constructed substantially in accordance with the preceding paragraphs in which an equal braking-effect is applied to each of two or more road-wheels.

The invention further consists in the improved equalizing under-carriages, trunnion, axle-boxes, and equalizing brake mechanism hereinafter described.

The invention also consists broadly in controlling lateral supports for a single-track vehicle in such a manner that they can only be lowered into position for supporting the vehicle when the vehicle is at rest.

The invention consists more specifically in lateral supports or legs sliding in guides and so arranged that they are actuated by means co-operating with the means which actuate the brakes.

The invention further consists in controlling the lateral supports by cylinders and plungers actuated by fluid pressure and arranged to be operated either in connection with or separately from the brake-cylinders.

The invention also consists in the improved lateral supports for single-track vehicles hereinafter described.

No. 27578.—19th April, 1910.—GEORGE WILLIAM MASCORD, of 5 the Crescent, Barnes, London S.W., England, Mechanician. Improvements relating to rotary motors and the like.*

Claims.—(1.) A rotary machine substantially as described. (2.) A rotary machine of the type specified, in which the piston is provided of segmental helical form upon the periphery of a rotor, the outer surface of the piston and the periphery of the rotor having transverse curvatures, which, when considered in the plane of one of the abutment-discs, are struck from the centre of the said abutment-disc, substantially as described. . . . (5.) A rotary machine or heat-engine of the rotating-piston type, according to the preceding claims in which an annular channel or recess is provided under the peripheral rim of the rotor, in which water may be retained by the action of centrifugal force, in the manner and substantially as described.
[NOTE.—Here follow twenty-one other claims.]

No. 27614.—22nd April, 1910.—CORNELIUS HOGAN, of Nightcaps, New Zealand, Labourer. An improved spark-arrester.*

Claims.—(1.) A spark-arrester consisting of a perforated hood of approximately semi-spherical form secured over the top of the smoke-stack and positioned to overlap the top edge thereof, and a water-chamber arranged around the outside of the stack beneath the bottom edge of the hood, substantially as specified. (2.) The improved spark-arrester constructed and operating substantially as described and explained, and as illustrated in the drawings.
(Specification, 1s. 9d.)

No. 27641.—27th April, 1910.—UNITED SHOE MACHINERY COMPANY, of Paterson, State of New Jersey, United States of America, a corporation duly organized under the laws of said State of New Jersey, carrying on business as Shoemachinery Manufacturers, and having a place of business at 205 Lincoln Street, Boston, Massachusetts, United States of America (assignees of John Benjamin Hadaway, of Swampscott, Massachusetts aforesaid, Inventor). Improvements in or relating to tack-pulling machines.*

Claims.—(1.)
