115,578	Jun. 06, 1871	Improvement in Water-Wheels	Ashly D. Cole	ON, Canada	This patent was improved by Canadian Patent #1807. Abstract: My invention has for its object to improve the construction of turbine water-wheels, to the end that they may be reduced in size, weight, and cost without lessening their power or efficiency. The invention consists in combining -with the stationary bottom of a cylindrical case, having straight inclined chutes, a revolving wheel provided with a beveled periphery and with curved buckets, which, in their upper half, are mainly perpendicular to a plane parallel to the chutes, and in their lower half curved downward nearly to a horizontal plane. Claim: he improved wheel formed by the straight inclined chute - plates E' and buckets G a, curved as shown and described, and secured in a ring beveled or flared outward at its lower edge, all arranged and operating as set forth.

5,888	Mar. 29, 1876	Thrashing Machine	John Abell	ON,, Canada	Abstract: The object of my invention is to prevent any grain being carried away with the straw and failing in passing through a thrashing machine and consists in a double row of fingers placed at the back end of the shoe and arranged so as to agitate the straw passing over them shaking out any grain lodged therein and loosening the straw so that the current of air may better pass there through. Also, in an improved screen for barley and oats, the holes in this screen are oval and for a portion of the length of the screen run longitudinally therewith, the rest of the distance being punched across the screen, which at this point is corrugated at and for the purpose hereafter explained.

33,944	Mar. 17, 1890	Steam Boiler Fire Box for Consuming Straw	John Abell	ON,, Canada	Abstract: The object of the invention is to construct a fire-box in which straw may be consumed without producing dust to fill up or clog the tubes of the boiler; and it consists, essentially, of a fire-box having its upper portion where the flues enter, partially separated from the lower portion by a hollow chamber extending from to tube-sheet to a point near the opposite side of the fire-box and provided with openings leading to the outside of the boiler to admit air, which is heated in the chamber and enters the fire-box though perforations in the chamber at a point where the heated gases pass on their way to the tubes. Claim: A fire-box having its upper portion, where the flues enter, partially separated from its lower portion by a hollow chamber extending from the tube-sheet to a point near the opposite side of the fire-box and provided with openings leading to the outside of the boiler to admit air, which is heated and escapes into the fire-box at the point where the smoke and heated gases pass the hollow chamber.
40,147	Aug. 30, 1892	Variable Cut-Off Engine	John Abell	ON,, Canada	This patent was improved by patent 50,048. Abstract: he object of the invention is to provide a simply constructed variable cut-off engine, in which the full boiler pressure is secured and the valve seats easily kept in order and it consists, essentially, of a cylinder provided with a steam reservoir within the body of the cylinder and in direct connection with the boiler and communicating with the interior of the cylinder through short ports located at each end of the cylinder at the mouth of the short ports and carrying grid iron valves operated by simple mechanism in direct connection with the governor, the whole being constructed in detail.

50,048	Sep. 21, 1895	Variable Cut-Off Engine	John Abell	ON,, Canada	Abstract: The object of this invention is to effect certain improvements in the valve seats and cut-off mechanism of a variable cut-off engine patented to me in Canada, under #40,147, dated August 30th, 1892. Claim: In a steam engine, a cylinder having a cylindrical chamber formed therein in combination with a removable cylindrical casing provided with seats for steam and exhaust valves and divided into two parts on a plane at a slight angle to the longitudinal axis of the casing so that by sliding the parts on one another, the casing may be tightened in place in the cylindrical chamber in the cylinder or loosened therein for removal.

60,739	Jul. 26, 1898	Engine Cut-Off	John Abell	ON,, Canada	Abstract: The object of my invention is to devise a reverse and variable cut-off, which will permit of the the widest possible range and accuracy of cut-off, which will reverse quickly and which is simple in construction and reliable in operation and consists, essentially, in operating the valve connecting rod from the crank disk pin on a slide adjustable on a suitably driven crank disk and provided with means whereby its position on the disk may be changed at will, while the parts are in motion. Claim: In mechanism for the purpose described, a slide having a wrist pin on which is thereon on which is journaled the valve connecting rod in combination with a disk having guides thereon in which the said slide may move: a suitably journaled sleeve on which the said disk id fast; means for revolving the said sleeve from some moving part; a shaft within the sleeve; a connection between the shaft and the slide whereby the latter may be moved by the turning of the shaft.
189,811,889	Apr. 22, 1899	Improved Reverse and Variable Cut Off for Portable and Other Engines	John Abell	ON,, Canada	Patented in Canada, #60,739. Abstract: Relates to variable cut-off and reversing gear for portable and other engines. The valve is actuated by an adjustable crankpin D, Fig. 2, carried by a disc F which is geared in the manner shown to the crank shaft K. The crank-pin is mounted on a slide E which can be moved across the disc by means of a pinion M in gear with a rack cut in the slide. The shaft L carrying the pinion is enclosed for a portion of its length in a sleeve H formed in one with the disc F and rotating in a bearing. The other end of the shaft L has adjustably secured to it a sleeve N also rotating in a bearing. The adjacent ends of these sleeves are enclosed by a sleeve 0, Fig. 3, in which is cut a pair of oppositely-inclined helical grooves d, d containing movable blocks e, e pivoted to the sleeves. The sleeve 0 has on it a collar or flange b engaged by one end of a bell crank Q, the other end of which is connected to a hand reversing-lever by which the expansion can be varied or the engine reversed while in motion. In mechanism for the purpose described, a slide having a wrist pin on which is thereon on which is journaled the valve connecting rod in combination with a disk having guides thereon in which the said slide may move: a suitably journaled sleeve on which the said disk id fast; means for revolving the said sleeve from some moving part; a shaft within the sleeve; a connection between the shaft and the slide whereby the latter may be moved by the turning of the shaft.
