Description

UNITED STATES ATENr OFFICE.
ALLEN J. SNIDER AND ALVIN L. KULP, AOF KEOTA, IOWA.
EXCAVATO R.
SPECIFICATION forming part of Letters Patent N o`. 295,451, dated March 18, 1884. Application tiled January 17, 1884. (No model.)
To @ZZ whom, it may concern.:
Be it known that We, ALLEN J. SNIDEE and ALVIN L. KULP, citizens of the United States, residing at Keota, in the county of Keokuk and State of Iowa, have invented certain new and useful Improvements in Excavators, of which the following is a specification, reference being had therein to .the accompanying drawings.
Our inventionrelates to machines for making ditches in the earth for drainage or other purposes, the peculiar nature of which will be hereinafter fully set forth. i
In the accompanying drawings, making part of `this specification, Figure l represents a longitudinal section, and Fig. of a portion of our machine.
In the iigures, A represents the two sides of a frame, which are secured upon axles carried by the wheels B B. Upon the frame, and near each end, are erected standards C C. Journaled in these standards are two windlass-bars, D D, which lie crosswise of the frame, and which have connected to them suitable pawls and ratchets and handles, by means of which they are operated and held in position.
Within the frame A is located a platform, E. To this platform, at each end, are connected cords ce, which pass around the windlassbars D D, and by means of which it is raised or lowered, as circumstances may require in regulating the depth to which the ditch is to be cut.
Through the platform E is cut an opening, F, up and through which the earth is intended to pass in its removal.l s
G represents an inclined excavating-plate, which is secured and suitably braced in the opening F. Thisplate is at an angle of about 2 a perspective,
fortyive degrees, or less, with reference to the platform, and its forward end is formed into a cuttingscoop. The forward endl of this plate is supported by the bars 1I and braced bythe brace H. At the upper extremity of the plate is a vertical cutter, J, and two wings, KK, for the purpose of cutting and dividing the earth, so that it will be thrown off to each side after being carried up.
The wings for throwing the earth to the sides may form a part of the plate, or may be inde= pendent of it.
In using this machine the platform E is lowered by means of its connections, so that the point of the plate G will cut to the required depth in the earth. The frame is then drawn forward, the bail L being first secured to the frame.
The earth passing up the inclined plate and through the opening Fis divided by the cutl ter J and passes off to each side. of the machine upon the wings K K. p
Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
rlhe platform E, provided with the opening F, inclined cutting-plate G, cutter J, and Wings K K, incombination with a frame on wheels, to which it is adj ustably attached and rendered capable of vertical adjustment, substantially` as and for the purpose set forth.
In testimony whereof we afX our signatures in presence of two witnesses.
