    Terry s Improvements in the Manufacture of Firewood. immediately after the date of the said in part recited Letters Patent, as in and by the same, reference being thereunto had, will more fully and at large appear. NOW KNOW YE, that in compliance with the said proviso, I, the said Alexander Robert Terry, do hereby declare that the nature of my said 5 Invention, and the manner in which the same is to be performed, are fully described and ascertained in and by the following statement thereof, reference being had to the Drawings hereunto annexed, and to the figures and letters marked thereon (that is to say):—- . , . < . My Invention consists of improvements in machinery for cutting or splitting 10 wood, and making the same into bundles suitable for firewood. Description of the Drawings. Figure 1 shews a plan of the machinery arranged or combined according to my Invention; Figure 2 is a horizontal section thereof; Figure 3, a right hand side view 5 Figure 4 shews a front view, with some of the parts removed, 15 in order that other parts may be better seen ; Figure 5 shews a vertical section of the machinery, and the other views shewn by the Drawings are detail views of some of the parts, in order that their construction may be more readily seen and understood. In each of these Figures the same letters are used to indicate the same parts, a is the framing, the nature of which is 20 clearly shewn in the Drawings; b is the main or driving shaft, which receives motioji from a steam engine or other power by a strap acting on the fixed drum c. The main shaft by means of the pinion d gives motion to the cog wheel e, fixed on the cranked shaft f which turns in suitable bearings, as shewn. The crank shaft / gives motion to the cross head g> by means of the 25 two connecting rods h, h. At each end of the cross head is fixed a plate g\ which is turned up at right angles so as to form a shelf or ledge g2 for the ends of the blades i, i, to rest on (the ends of the blades i, i, being notched out in order to their resting on such shelves or ledges g2 g2), and the upper surfaces of the blades i, i, will, at intervals in their length, be pressed on by 30 the cross head, and the blades are kept in a vertical position by means of springs or plates j> j, of steel, which are fixed at their upper ends above the cross head, and there are openings through the cross head for the passage of the springs. By these arrangements the blades z, iy when out of the wood, will all be closed upon by the spring plates j, which will cause them to range 35 near together; but so soon as they penetrate the wood, and the blades thereby become more and more separated, the springs separate and allow of the sepa¬ rating of the blades to a greater distance apart; but so soon as the blades
