' HOF- IMlPROvED EXCAVATOR.
The Schedule referred to in these Letters'Patent 4and making-part of the same.
Be it known that I,.'JOHN.R. LEWIS, of Piper City, in. the county of Ford,rand State of Illinois, have inivented an Improved Excavator; and I do hereby deolare' that the following is a full, clear, and exact .description thereof, which will .enable those skilled inthe art to make' and use the same, refereneebeing had tothe accompanying drawings, and letters marked there0n,.making a part of this specification, in which Figure 1 is a perspective representation of my improved excavator;
Figure, a broken plan view-0f parts appertaining thereto.
Figure 3, a perspective view of the plow removedfrom lits beam.
Figure/1, a'bottom view-of the plowyand lower part of the elevator. Y
' 'The presentinvention' relates to an improvement in that class of excavators which is mounted upon wheels, and arranged, by suitable mechanism,.to elevate -the earth, and deposit it at one side of a ditch, or 'a plaeeothatis being graded; and
Its nature consists inthe novel` constructionof the plow, and the novel manner in which it lis combined with the elevator.
Also, in the peculiar' arrangement of the devices employed to operate the shovel and elevator, as the whole vis hereinafter ,fully described.
B B represent the running gear of an ordinary farm wagon,` provided with a box-frame, A A', for supporting the workingparts of myinvent-ion.
The'rear part, A', of the frame is made at one end to4 project over one of the side4 pieces A,'and to extend down far enough to provide a suitable support` forone end of a plow-beam, '.l. The part projecting downward `being slotted out, allows thebealn to be raised or lowered between the depending standards J K', which are provided with holes'V V', in vwhich a pin, V, is pntto'hold thereai end of the beam in a fixed position when adjusted to the required' height.
A beam, v4H, is fastened tothe forward palt of the side pieces A A, 'and'it projects over one of the flame-pieces A, on the same side that the part A projects, far enough tol support depending' standards L K, between which the forward end of the beam l is held. Said beam being provided with .two lugs .U, bearing against the forward sides of the standards, is held firmly against the draught. of the plow I), and the stand ards LK being strengthened by a brace, M, bearing yagainst the side piece A, are held in vertical positions. 'i
In order to provide means within the convenient reach of the operator, for raising and lowering the forward end of the beam T, a wheel, I, is placed abovethe 'asshown at tig. 4.
beam and on its shaft, which has bearings in the beam H, and a standard, J, attached to the standard L, is wound a rope, rc, which vfas'tens to said beam, -so that when the wheel isturned, the beam lwill be raised or lowered, as the ease may be.
Any suitable catch may be used to lock the wheel in any given position, if desired.
The plow consists of a point, D, landside E, standard F, and mould-board, W. The latter having its outer wing at W,`as,shown`at figs. land 3, curved up, prevents the earth, as it is being carried up toward the elevator X, from falling on".
The mould-board and .landside are connected together by means of an iron i)iace, g, securely lbolted to the aforesaid parte, and pivoted to a strap, t, which is rigidlyattached to the shoe-plateX of the elevator, andV h'asa series of holes made through it for the convenience ofso changing the posit-ion of the bolt, with which the brace gis fastened, that the landside D may be set to orfrom the lower end of the elevator,
The plow has its shhnk bolted fast to the beam at F, thus supportingthe front lower corner of theelevator,- the other end of the elevator Abeing supported by nieansof a chain, Z, fastened to a pin in the top,
of said beam.
The elevator consistsof two stiles 0, strengthened by a tie, N, and shoe-plate, X. The'upper ends of these stiles are held to projecting beams G G, fastened to side pieces A A, by means of cleviscs Q, figs. l'and 2, which pass over said beams, and have holes through tl1eir'lowe1'-ends, to receivea pivot-rod, l.
The lower end of the elevator is provided with a roller, Y, and the out-er ends of the beams Gr, with aA roller, C, around which an ordina-ry endless belt, for
`)ne of thehind wheels ofthe wagon:
vTo enable the pinion S to be thrown out of gear with the pinion 71, the joumal of roller C, in the beam G', has a'slotted bearing, whereby, when a key, b',`iig. 2, is driven into a tapering niortise in said beam. the pinion S will be moved outward.
"lhe device, as described, will be found veryconveulent for cutting any depth, from one to eight inches, in au easy and satisfactory manner; and as any ordinary farm-wagon can be used for the running gear, a very great saving is Iliade in the cost, as the excavating-attachments can readily be removed by lift-ing ciik 1. The plow, provided with :t mold-board turned up at W, to. (arry earth on to the elevator, in combination with the brace g, shoe-plate X, and connectingplate t, as set forth.' as and for the purpose specified. y
