.To a/ZZ whom, it may concern.-

Beit known that we, ANDREW J. WILLIAMS, residing at Gilmore City, in the county of Humboldt,and MrRoN M. HEr'roNsTALL, re-

5 siding at Pioneer, inthe county of Pocahontas, State of Iowa, citizens of the Unitedx States, have invented a new and usefulDitching-Machine,of which the following Vis a speci- 'icatioir This invention relates generally to ditch-1 ing-machines, and more particularly to that class thereof known as tile-ditchers or one intended to out a narrow trench inthe earth.

The object of the invention is to provide a I5 strong, durable, and efficient ditching-machine which can be regulated to dig or cut ditches of any convenient depth desired; and another object of the invention is to provide a ditching machine in which the strain will 2c be evenly distributed; and astill further object is to provide a machinein which the plow will be pivotally Aswung in an open frame, whereby7 free rearward and vertical movement of the plow is permitted when an ob struction is encountered.

Another object of the invention is to provide a machine embodying the characteristics herein mentioned which will only require the attentionof two men for the purpose of 3o manipulating the same-one man serving as driver and the other one serving to effect the adjustments of the various parts, all of which are eiected from the rear of the machine.

With these various objects in View the invention consists in the novel construction of the frame for carrying the various parts of the machine, in the novel means for adjusting the plow, the conveyor, and the dischargebelt, and inthe novel means for throwing the 4o plow upwardly wheneveran obstruction is encountered by the said plow.

The invention consists also in certain'details of construction and novelties of combination, all of which will befully described hereinafter and pointed out in the claims.

Fig. I5 is a detail sectional view on the line I5 l5 of Fig. I4, and Fig. 16 is a detail view of the clutch mechanism for throwing theV machine into and out of opera- 8o tion.

In carrying out our invention we employ a frame which is supported upon the front axle l and rear axle 2, carrying the wheels 3. The front axle is movable after the manner of an ordinary front wagon-axle, being provided with a ifth-wheel 1iVL and has a draftpole lb connected thereto. Front and rear bolsters 4: and 5 are arranged above the front and rear axles, respectively, said holsters hav- 9o ing the upright standards 6 connected thereto and extending upwardly therefrom, said standards being connected at their upper ends by means of the horizontal longitudinal beams 7, said beams being braced by means of arched truss-bars 8, said truss-bars being preferably constructed of angle-iron'and rest upon the front and rear bolsters, as most clearly shown in Fig. I. These front and rear bolsters are also connected by parallel roo horizontal beams 9, which beams may be of wood or metal, as preferred.

The plow is made substantially in the form of a scoop open at the rear end and comprises the bottom 10 and sides 10", the bottom being provided with a detachable point 10, and the sides are providedwith detachable cutting edges 10d. Avfoot-piece 10e is arranged upon the under side of the bottom. This plow is connected to a standard 11, which is bifurcatcd adjacent its rear end, each member 11L being connected to one side of the plow, as most clearly shown. This combination plow standard and beam 1l has two or more journal-boxes 12 arranged transversely thereon, and passing through the said journal-boxes are the arched bails 13, the ends of said bails being journaled in bearings 14, connected to the parallel side bars 15 v of a frame intended to carry the plow, said parallel side bars being connected at their forward ends by means of a crosspiece 1G and at their rear ends are connected by means of a yoke 17, said yoke being curved or arched sufficiently to permit the free movement of the plow and its standard or beam. A fiat upright bar 18 is connected centrally to the cross-piece 16 and extends upwardly through a strip 10, connecting the front uprights 6, the upper end of said vflat bar having a plurality of horizontal apertures 1S, through which a spring-actuated locking-bolt 2O is adapted to pass above the strip 19, said sp1-in gactuated bolt being connected to a foot-lever 2Oa by means of a link-rod 20h, said lever being pivoted upon a platform 20C, arranged below the drivers seat and between the front standards G. By operating the foot-lever the bolt can be thrown into 01 out of engagement with the apertured bar 1S, thereby locking the plow-carrying frame in any desired adjustment. In order to raise and lower this plow-carrying frame, we employ front cables or chains 2l, con necti d to the side bars 15 adjacent their forward ends, and the rear cables or chains 22, connected to the rear ends of the side bars. The chains or cables 21 are connected to a horizontal shaft 23, journaled in the frame, and the rear cables or chains are connected to a horizontal shaft 24, journaled also in the frame, said shafts 23 and 24 having lheir ends extending through the frame at the left side thereof and are provided with the beveled gears 23 and 24, respectively, which gears mesh with beveled gears h and 24h, respectively, said gears 23h and 24" being mounted upon a shaft 25, which extends parallel to thev beam 7 and is journaled in brackets extending laterally from said beam, said shaft being operated by a crank 25a, mounted upon the rear end of the shaft, said crank being arranged conveniently for the operator, who stands upon a platform 26, projecting rearwardly from the frame. -An ordinary pawl-and-ratchet mechanism 25" is connected to the shaft 25 adjacent the rear end for the purpose of holding said shaft locked after it has been properly adjusted and also for the purpose of permitting intermittent rotation of said shaft in one direction. It will thus be seen that by operating the crankhandle the shaft 25 will be rotated and will impart motion to the winding- shafts 23 and 24, so that the plow carrying frame will be raised or lowered asdesired, it being understood, of course, that the locking-bolthas been previously disengaged from the bar 1S by pressing upon the foot-lover 20f. The shaft 23 also carries a sprocket-wheel 27, over which passes a chain 27 a, which drives a sprocket 27 b, which is mounted upon the end of the shaft 2S, carried by the uprights G, said shaft having a chain or cable 29 connected to the center of the same, said chain or cable passing around a pulley 29, carried by the draftbeam under an antifrictionroller 29h, arranged beneath the front axle, the lower end of the chain or cable being connected to the cross-piecel of the plowcarrying frame. By means of this chain or cable 29 the full force of the draft can be applied directly to the front end of the plowcarrying` frame, and by having the upper end of the said chain or cable connected to the shaft 2S, which in turn is connected with the winding- shafts 23 and 24, it is obvious that as the plow-carrying frame is raised or lowered the draft chain or cable is let out or taken up, so that the proper tension upon the draft chain or cable is always maintained.

One of the bails 13 is connected to a bowshaped b arSO by means of an eyebolt 30a, said bow-shaped bar being pivotally connected to an arm 31, pivotally connected to a bracket 31, connected to one of the side bars 15 of the plow-carrying frame, said arm having a threaded eye 311 at its free end, through which passrs an adjusting-screw 31C, the end of which is adapted to bear upon the bowshaped bar 30, as most clearly shown in Fig. 12. A curved link -arm is pivotally connected to the bowed portion of the. bar 30, the rear end of said link-armbeing connected to the crank-arm 33, which is operated by the cranklever 34, to which the rod 35 is connected, said rod extending to the rear end of the machine, and by pulling upon said rod the plow can be raised whenever desired, inasmuch as the upward and forward movement of the link-arm 32 will cause the bar 30 to be lifted, carrying with it the bail 13, which supports the plow. In case the plow should encounter an obstruction the said plow willbe thrown upwardly and rearwardly, the pivotal connection between the arm 31 and bar 30 permitting such movement, and the regulatingscrew is employed to regulate the tension at which point the said parts will break upwardly to permit the plow to swing clear of the obstruction; An endless conveyer 36 is arranged with its lower end directly at the rear of the plow, so that the dirt will be discharged directly upon the upwardly-traveling iiight of the said endless conveyer, and the earth so elevated is dumped upon an endless discharge-conveyer 37, the upper end of IDO IlO'

which is arranged directly beneath the upper end of the endless elevator, and the lower end of said discharge-conveyer projects laterally beyond the frame, so that the excavated earth can b e discharged alongside ofthe ditch as the machine progresses. The forward end of the elevator 36 is connected to the rear end of the plow carrying frame by means of link-arms 3S, so that as the plow-carrying frame is raised or lowered the forward ends of the conveyer will be correspondingly raised or lowered. Chains are cables 39 are connected to the sides of the elevator adjacent the rear end, said chains or cables being connected to a horizontal shaft 40, which has a beveled gear 40a mounted upon its projecting end, which gear meshes with a gear 40h, mounted upon the shaft 25, so that as the said shaft 25 is operated to raise or lower the plow the shaft 40 will be operated to raise or lower the Vrear end of the'elevator 36. The endless conveyer is operated by means of a sprocketchain 4l, which passes around a sprocket wheel 42, mounted upon the end of the conveyer-roller, said spocket-chain receiving its motion from a sprocket-wheel 43,v mounted upon the end of a shaft 44, carrying a gear 45 at its oppositeend, which gear meshes with a larger gear 46, mounted upon the rear axle.

A clutch 47' is arranged upon the shaft 44, which clutch is operated by means of a lever 47a, so that the mechanism can be thrown vinto vor out of engagement when desired. A

belt-tightening lever 4S, carryin ga pulley 48a, takes up the slack in the sprocket-chain 4l whenever the endless elevator is adjusted, said lever being held in a locked position by means of a ratchet-bar 48h, with which the said lever contacts, as most clearly shown in Figs. ll and 3. If desired, both the Lipper and lower rollers of the elevator may be provided with sprocketwheels and a sprocket-chain 49 passed thereover, so that -the elevating-apron will be positively operated from both the upper and lower ends.

The discharge-conveyer 37 is supported in its proper position by means of chains or cables 50, connected to a longitudinally-arranged horizontal shaft 5l, journaled upon a supplemental frame 52 and provided with an operating-crank 5l, and a pawl-and-ratchet mechanism lb is arranged in connection with the said shaft for the purpose of locking it in any desired adjustment. It will be noted that the shaft 5l and chain are arranged to one side of the endless elevator, as most clearly shown in Figs. 2 and 3. The

i endless apron of the discharge-conveyer is operated from a sprocket-wheel 53, mounted upon the rear axle and driving a sprocketchain 54, which in turn drives a sprocket 55,

mounted upon'a short shaft 56, journaled at the rear end of the frame, and this sprocket 55 has a gear 57 integral therewith, which meshes with a beveled v gear 58, integral with the sprocket 59, mounted upon the sh aft 60,which passes through the conveyer-frame and is journaled in the' depending ends of the supplemental frame, said'shaft serving asa pivot .can be thrown out of mesh, thereby stopping the operation of the discharge-conveyer. It will of course be understood that the handlever 56a is provided with a suitable latch mechanism for holding the same locked in the proper adjustment.

In Figs. 8 and 9 we have shown a slight modification in the construction of the plow, said plow 63 being in the form of a scoop; but it is not constructed with the removable point and side pieces. In connection with this construction of plow we employ two colter-disks 64, which travel directly in front of the sides of the plow, said colter-disks being pivoted to the lower ends of the bent standards 65, which are connected to each other at 65a and to the plow-beams ll at 65". It will also be noted that the bails 13 pass directly through the plow-beam, thereby dispensing with the boxes 12.

In operation the machine is arranged in alinement with the ditch or trench to be dug, andthe p'low is inserted in the earth and the machine drawn forwardly, and as the machine moves forwardly the plow will cut into the earth a definite depth, which'depth is regulated by the position of the plow-carrying frame, and ordinarily the plow is adjusted so that it will cut about one-half the totalrdepth of the ditch, and after cutting the ditch onehalf the proper depth the plow frame is lowered, so that the plow willcut the remaining depth of the ditch. As the plow scoops out the earth the said earth passes out through the open end of theplow onto the upwardlymoving endless belt of the elevator, from which it is discharged upon the endless apron of the discharge conveyer, which is moving outwardly, carrying the earth and discharging the same to oneside of the ditch or trench. The plow-frame is raised or lowered from the rear of the machine by turning the crankhandle 25a, and simultaneous with the movement of the plow-frame are the movements of the draft chain or cable and the chains or cables supporting the elevator-conveyer. The inclination of the disch arge-conveyer can be quickly and easily adjusted by means of the crank 5l, and the entire operating mechanism, with the exception of the plow, can be thrown out of operation by means ofa clutch 47 and lever 27?. The plow can be raised whenever desired by pulling upon the rod 35, and by connecting one ofthe bails to the bar 30 and arm 3l the plow will be automatically lifted whenever it encounters an obstruction.
