  • the mowing-machine Vas improved is constrnctedinthe following manner :Y'lwo wheels tive feet six inches in diameter are constructed in the usual manner with-hubs, spokes, fellie's, and tire likethe 'wheels otacomlnon cart, except that the rim and tire of the'o' wheel is o( the vusual Width of rim fand tire, while the rear wheel has a rim and tire of twice thewidth,jan'd that the tire of this latterwheel-is iprovided with small teethor cogs to prevent its-slipping on the ground.
  • the wheels run on 4different axles, but both axles are on the 'same straight line'.V
  • a frame-work to connect these'wheels together and to support the whole machinery is constructed in the following manner: ⁇ A piece of plank' three by seven inches and six feet long, whichby way of distinction may be called noisy-1,77 is laid units center on the axle ofthe near wheel, close tothe hub, at his axle
  • No. 2 isanother piece'of plank of equal dimensions.' It extends diagonally from the rear end-ot No.1, ⁇ to which itis mortise'd,to the axle ofthe ofi' wheel, close to the hub,where it is lnortised to No. 3.
  • No. 3 is a plank otiequal dimensions, one 'end of which is'mortisedto No. 2, as aforesaid.
  • This piece forms with No. 2 an' angle of eightyzdegrecs. The other end extends diagonally toward the front ot' the rear side of the carriage.- On a line with the 'front of the wheels is apiece of plank ofthe same width and thickness, No.
  • hub of the ott' wheel' is another piece ofplan-k lof equa-l width and thickness, No. 6.
  • '1 his piece isexactly paralleto No.5,withone end lnortised to No. 2 and the other to a cross-piece, No. 7, which connects Nos. 3 andl 5.
  • No.6 is fastened thel center end ot' the stationary axleot' theotl'- wheel.
  • Thisv axle ⁇ is also fastened near the hub to ⁇ No.2; Inthe interstice between the planks 'hilos'. 5 and Gand-Nos. 2 and 7 is a.
  • ver- ⁇ tical iron shaft with a pinion on it, and also a Vvertical cog-wheel.
  • This ver tical shaft is placed immediately inthe cen-ter ot' the whole machinery between the center ends-ot' the v two axles.
  • the pinion is under the frame-work,-
  • the shaft is l'our feet long.
  • the lower part of it is encompassed by an ircn collar, which is .fastened hyl two screw-boltsthat maybe moved backward or forward for the purpose of regu'- lat-ing theedge (when required) ina horizontal groove in the bottom of an iron frame,wh ich is supported hy four iron stanchions, two connected withv the plank No.il on each ⁇ side ot'- 'the axle', one with No.. 2, and one with No. 3.'
  • the endsot' the stanchions which are connectedy with the plank No. 1 are bent to va horizontal knee, so as -to .pass horizontally through the plank, and havnga screw-thread worked uponeach, and being provided .with a nut on, n

  • the hub of theliorizontal wheel is formed by riveting together two plates of iror'rwith blocks between, forming what by millwrights is commonly called a block-wheel.
  • the interstices are wooden arms or spokes, which are (lished out 4or inclined upward, at;A the endof which is an iron knee, bent first vertically and 'the-n horizontally, to which is fastened an outer circular frame ot' wood, on which ⁇ the scythes are screwed.
  • the inner part of this wheel is surmcuuted witha circular box inverted.
  • The; scythes are sections oi' aV circle screwed to vthe periphery of the horizontal wheel, so as to form a continued circle of soy thes, the edge outward.
  • Under the horizontal wheel is a runner, in one end of which thevertical lshat't revolves. The other passes to the rear of the horizontal wheel, where it has a chain orcord attached toit, which chain or cord,'after passing over a pulley fixed' in a frame at the rear of the carriage, is fastened to the end of the lever before described.
  • the shafts are aixed to the carriage in 'the fol- Y lowing manner: lmmediatelyover the axle of the near wheel is a cross-piece extending from i the plank No. 1 to No. 5. To this piece is fast-v ened the rear end of the oli' shaft. A bolt also passes through this shaft and plank No.'4, and another through this shaft and the front end of No, 3.
  • the near shaft at its rear end is fixed to a perpendicular barV terminating in a collar at the lower end, through which the'axlepasses and revolves outside of the hub.
  • Across-piece extending from one shaft to the other is fastened by ascrew-bolt to the front end-ot' No. 1.
  • On the near shaft is a hook, to which the end of the lever may be hitched when depressed, as
  • the circular frame vto which the scythes are l screwed is of wood,whichis another improvement.
