(12.) In a self-propelled or motor vehicle, an internal-combustion engine having its connecting-rod reciprocating in a horizontal plane, and a fly-wheel of a relatively large diameter rotating in a plane parallel to that of the connecting-rod and extending for nearly the full width of the vehicle, so as to increase the stability of the vehicle by its gyroscopic action. (13.) In a self-propelled or motor vehicle, an internal-combustion engine having its connecting-rod reciprocating in a horizontal plane, and a fly-wheel of a relatively large diameter rotating in a plane parallel to that of the connecting-rod, and extending for nearly the full width of the vehicle, so as to increase the stability of the vehicle by its gyroscopic action, and projecting a current of air upon the cylinder or cooling-water vessel, or both, for cooling purposes, substantially as described, or illustrated in the drawings. (14.) In an internal-combustion engine for self-propelled vehicles, a vaporizer and heater for the explosive mixture, comprising a tubular member such as O, through which the mixture passes within a casing such as N, through which the products of combustion pass, substantially as described, and illustrated in Fig. 1 or Fig. 4 of the drawings. (15.) In an internal-combustion engine for self-propelled vehicles, a vaporizer and heater for the explosive mixture, comprising a chamber such as F within a casing such as N, constructed and arranged substantially as described, and illustrated in Figs. 5 and 6 of the drawings.

No. 12257.—21st December, 1899.—WILLIAM ERNEST HUGHES, of Queen’s Chambers, Wellington, New Zealand, Patent Agent (nominee of the Plano Manufacturing Company, a corporation organized under the laws of the State of Illinois, and having its principal office at Chicago, Illinois, United States of America, the assignees of James Macphail, of 447, Gregory Street, Blue Island, Illinois aforesaid, Master Mechanic). Improvements in grinding-machines for harvesting-knives, also applicable for other like purposes.

Claims.—(1.) A grinding-machine comprising a grinding-wheel, a pivoted frame carrying the wheel at one end, and having an extended portion at the other end beyond the pivotal point, an eccentric co-operating with such extended portion to vibrate such frame, a frame carrying such eccentric and adjustable in position to vary the position of arc of vibration. (2.) A grinding-device comprising a vibrating grinding-wheel frame, a grinding-wheel therein, mechanism for vibrating the frame, a driving-wheel operating said mechanism and simultaneously rotating the grinding-wheel, and means for throwing said mechanism out of operation and simultaneously locking said mechanism. (3.) A grinding-device comprising a base portion or support having a journal, a main shaft in such journal, a rotatable grinding-wheel, a frame pivoted on said shaft, carrying at one end the grinding-wheel and having an extension at the other end beyond its pivotal point, an eccentric contacting such extension to vibrate the frame and the grinding-wheel, a gear actuating the eccentric, a main driving-gear wheel rotating the grinding-wheel and having a pinion meshing with the eccentric actuating gear. (4.) A grinding-machine comprising a base portion or support, a main shaft mounted therein, a rotatable grinding-wheel, a frame pivoted on said shaft, carrying at one end the grinding-wheel and having a bifurcated arm extending beyond its pivotal point, an eccentric located between the bifurcations of said arm and adapted to vibrate the frame, a gear-wheel actuating said eccentric, and a main driving-gear wheel arranged on the main shaft, and adapted to rotate the grinding-wheel, and having a pinion to actuate the eccentric actuating gear-wheel. (5.) A grinding-machine comprising a standard or support, a main shaft mounted therein, a rotatable grinding-wheel, a frame pivoted on said shaft, carrying at one end the grinding-wheel and having a bifurcated arm extending beyond its pivotal point, an eccentric located between the bifurcations of said arm and adapted to vibrate the frame, a gear-wheel actuating said eccentric, means for removing it from mesh from its driving-pinion to prevent vibration of the frame, and a main driving-gear wheel adapted to rotate the grinding-wheel and having a pinion to actuate the eccentric actuating gear-wheel.
