DITCHING -MACHINE.

SPECIFICATION forming partof Letters Patent No. 543,257, dated July 23, 1895.

' Application filed May 1,1894. Serial No. 509,671. (No model.)

To all whom it mayconcern:

Be it known that L'ALEXANDER MANN, of Berkshire,in the county of Sanilac and State of Michigan, have invented a newand Improved Ditching-Machine, of which the following is a full, clear, and exact description. The object of the invention is to provide a new and improved ditching-machine, which is comparatively simple and durable in construction, very effective in operation, and arranged to readily dig up the ground and transport the same to a desired place for dumping.

The invention consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

' Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of'the im} provement. Fig. 2 is an enlarged sectional side elevation of the same. Fig. 3 is a sectionalplan view of the same. Fig.4. is an enlarged sectional side elevation of a frictionclutch, and Fig. 5is an enlarged transverse section of the maindriving-shaft and clutch mechanism.

The improved ditching-machine is provided placed on the ground to be ditched, and in thishousingis journaled a main driving-shaft B, carrying at one end a pulley B, over which passes a belt B also passing over a pulley on the main driving-shaft of an engine or other On the shaft B are mounted to rotate loosely the two winding-drums O. and C, on which wind the ends of the runs C and C of a carrierrope or chain, extending through the front end of the housing A to pass beneath guide pulleys A on the housing A,-and thence along the place to be ditched, as plainly illustrated in Fig. 1. The winding-drums O and G are adapted to be thrown into and out of gear with the hub D on and rotating with the E and E, respectively, both alike in construe tion and adapted to scrape up the ground so as to form the ditch, as hereinafter more fully described. The outer end of the carrier-rope or chain passes over pulleys F held on a crossbar F, connected by' a rope F a chain, or other means, with a stump or other post or projection at the outer end of the ditch to be formed. (See Fig. 1.)

In order to permit of removing the scrapers E and E from the runs 0 and O of the carrier rope or chain, I provide each run with a Ushaped bail 0 adapted to be hooked into scraper and at the front end thereof, as plainly illustrated in the drawings. The eye E on the back of the scraper connects with a hook on the respective run, so that the scraper is readily moved forward or backward, accordingto the direction in which the corresponding run 0 or (J is traveling. Each scraper E and E is provided with suitable handles E adapted to be taken hold of by the operator, so that when the corresponding scraper is on its forward movementthe operator tilts thescraper to carry the front end downward. Then this end passes into the ground, scrapes up the dirt, and when the scraper is filled in this manner the operator releases his hold on the handles E to let the scraper be carried forward with its load.

Now, it will be seen that. when the several parts mentioned are'in'the position shown in Figs. 1, 2, and 3, and rotary motion is given to the main driving-shaft B, then the drumC will wind up its run 0 while the other drum C, on account of being disconnected from the shaft 13, permits its run 0 to unwind. Thus the scraper E moves inward toward the housing A, and at the beginning of the operation the operator manipulates the scraper so as to fill the same, as above described, and after it is filled it travelsinward in the direction of the arrow 0.. At the same time the other empty scraper E movesoutward in the inverse directionof the arrow a. to be returned to'the place for filling the scraper on changing the position of the clutches D and D. When the too end of the run at the eye E and an empty scraper is inserted in said run. A cranev is now brought into use so as to lift the filled scraper and to swing the same to one side of the housing or to the rear thereof, or over a boat, car, or other suitable vehicle, to dump the contents of thesaid scraper. As shown in the drawings, I provide a hoisting device G, having the hooks G, adapted to hook onto eyes E on the top of the back of the respective scraper, as plainly shown in Figs. 1 and 2. A third hook G extends forwardly and engages. the front scraping-edge of the scraper to support the latter in a horizontal position with out raising and moving it to one side of thehousing. The. three hooksG andGr. areheld at their upper end. in aring G?,,su1pp'ortediloni asheave Ghung in. a hoisting-rope HI fats: tened at one end to] the, boom. II and passing over a pulley fl jonrnaled in, the, said boom near. the upper end. The boomthl' is journaled on, the-front end of, the. housing A.,,as. plainly showninthedrawings. Thethoistizng; rope I-l', after leaving the pulley; H passes over a. pulley H on. the thetopofi the housing A,,and then the hoisting-rope passes (105M117 ward; through the top. of the housing into the latter and to a. hoisting-drum HS mounted; to rotate loosely on. a transversely-extending shaft I-I journaled, in suitable bearingswith; in. the housing A. Aclutch mechanismihli 'is adapted to connect the said hoisting-drum; with, a. sleeve or hubv I1 journaled. insui-table bearings and secured onthesaid shafhHF, the.

said hub. carrying a gear-wheel, H in, mesh;

with the gear-wheel D? securedonthehubDfpreviouslyv mentioned, the said. hub rotating; with, the main driving-shaft .B, as above. de, scribed. (Seealso Fig, 5,) Thusthe rotary motion of the mainidrivingrshaft B- istran initted by. thegear-wheels D 'and.

Now, in order to swing the boom, H! seasv to move the hoisted and. loadedv scraper. to one, side, the following, device is provided: Onthe upper end of thevertical shaft of; the;

boom His secured a: wheel I, connectedon opposite sides of itsrimwith the ropestl and. l passing over pulleys I into,the interior of the housing A, the said ropes winding, on drums I and 1?, respectivelygeach securedon a shaft 1 having a frictiomwheell. adapted to both rown infrictionaltcontact with-a fric; tion-wheelH on the sleeveonhub.

ing shaft 17 from the continuously-rotating I hub I17. Each shaft 17 has one endzj ournaled. in suitable fixed bearingsierectedtinithemasr K ing A, whilethe other end of, the shaft is.

When the clutch mechanism H5 is journaled in a lever 1 (see Fig. 4,); adapted to; be; actuated by a treadle I under control of the operator. Now it will be seen that when the operator presses the treadle I for either the drum I or 1 then the corresponding friction-wheel I of. this drum is thrown in. frictional contact with the corresponding friction-wheel 1-1 to cause a rotary motion of this drum to wind up the rope I or I It will be seen that when one drum is thus rotated and its rope wound up the other loosened drum, revolves freely in. an opposite direction to permit its rope to-unwind. Now the rope :I" or Kin being wound up, causes a pull on the wheel I so that the latter is rotated either to the right or totthewleft accordi-ng to whichzr opei is wound up, The movement of the wheel causBS-asw-ingingot therboom Ilflso as tonnovethe-load to, onesidesofi thehousing A.
