Know al1 men that I, EMORY BARNES, of Chelsea-,inthe county of Washtenaw, and Stato of Michigan, have invented a new and useful Improvement in Ditching-Machines for swamp land; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to thc letters of reference marked thereon, and being a. partof this specification.

fThe nature of my invention consists in adapting any forni of dredge used in deepening water-channelgto the excavating of ditches, particularly in swampy lands, which are of too soft a nature to permit ofthe use ot' horses with Scrapers and horse-shovels for ditching purposes.

In order that those'skilled in the art may understand its construction, I will now proceed to describe my invention, and name its vari-ous parts.

Y Y'representtwo sillsor runners, supporting the whole apparatus, Framed thereto are the vertical posts A A, which are surmoun'ted by the armed beam B B, supporting the cross-tree C, thc'who'le secured in position bythe braces A2 A2. D isa vertical shaft, to which are firmly secured the pulleys E, G, and H, all operated by rope or chaiii R, windla'ss Y, and lever- W, in connection with pulley H. F is a block, loosely sleeved upon the shaft D, to which is swivelled the end of the crane I bythe bolt 2. J isfan excavator-lever, pivotcd near its centre to the outer end of the crane I, by the pin 3, and to which is attached the dredging-scoop K. U is a platform, erected upon the sills Y Y,- at a sucicnt 'height to clear sides of thc ditch, while -t-hc sills rest upon the bottom of the same. V is avertical capstan or shaft, provided with the lever W, winding the ropcor chain R,

and giving motion to the shaft D.- By Vthe backward motion of the capstan, the rope It is released, and the lower end of the excavator-lever, with` the excavator, being the heaviest, gives a constant strain upon the line P, which is connected to the upper end ofthe lever Jand thecylin'der E. By the release of the draught-rope E, reliev` ing the shaft D and cylinder E, the excavator-lever, operating as described, assumes a vertical position by the release ofthe line I), the stay-line S opcratingras a gauge to the depth of the excavation. The crane I and its attachments, when not operated upon-bythe line P, by means of the cross-bar M, attached to the crane I, near its outer end, provided with the' lines N N, passing through the blocks O O downto aplace convenient for operating by hand, give the excavator the lateral swing required.

vT is a line, attached to the outer end of the excavator-lever J, passing through the crane I, over and through the cross-bar C, to a convenient position to be operated by hand, for the purpose of drawing back the excavator K from a vertical position, when required, and to allow the same to enter thesoil at an angle which secures thc v greatest. amount inits passage. L is a trap-bottom of the excavator K, provided with a self-fastening latch, to

which is connected the hand-line Q, releasing the trap-bottom of the' excavator K, and discl1argin` its contents when required. When it is desired to move the apparatus forward, one end of the rope X being secured to some stationary stake or post at a proper distance in advancegthe other end is wound up on the drum G, through the arrange ment of the capstan V and the rope R operating upon the-pulley II, thus moving the apparatus ahead as required.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the sills Y, the posits B, the cross-tree C, the beam B, the braces A2, the vertical shaft. D, pulleys E, G, and H, the chain or rope R, windlass V, lever W, block I?, crane I, bolt 2, lever J, scoop K,

platform U, capstan V, linesil?, S, N, T, and Q, cross-bar M, blocks O, and rope X, when arranged, constructed,

and operating substantially as and for the purposes herein set forth and shown.
