Original No. 884,068, dated April 7, 1908, Serial No. 386,714. Application for reissue filed July 25, 1908. Serial To all whom 'it may concern:

Be it known that I, MoRToN Gr. BUNNELL, a citizen of the United States of America, and resident of Porter, Porter county, Indiana, have invented a certain new and useful Improvement in Ditching and Grading Machines, of which the following is a specification.

My invention relates to ditching and grading machines of that kind in WlllCh the soil is torn up or disrupted by a plow, and then carried by a suitable conveying apparatus to a point where it is discharged from the side of the machine. In the use of machinery of this character, as heretofore constructed, it has been impossible to run the machine in opposite directions in'the same excavation or cut and discharge all of the dirt so excavated on one and the same side of the excavation or cut. In certain kinds of work, where it has been necessary to discharge all of the dirt on one side of the excavationas in the case of a ditch excavated on the side of a hill, where all of the excavated dirt should be deposited on the lower side, or in the case of a road which has a sufiicient ditch on one side, but none on the other, and it is desired to excavate a ditch entirely on one side of the roadit has been necessary to run the machine idle in one direction, thereby limiting the capacity of the machine by one-half, and increasing the time neces sary to complete the work. This, of course, is necessarily true where the machine has a plow only at one side thereof, and is capable of discharging the soil only at one side, be cause such a machine is not reversible 0r capable of working in either directionthat is to say, is not capable of throwing the dirt in the same direction, regardless of which way the machine is traveling. It is obvious that considerable time would be saved and efiiciency gained by employing a machine which can run or Work in either direction that is to say, which is "capable of running along one side of the road or cut in one direction, and which is then capable of turning around and working back along the same side of the road or cut, throwing the dirt in the same direction each time. In other words, much time and money will be saved by the use of a machine which is capable of plowing at either side, and which is capable of discharging the soil from either side thereof, regardless of which plow is being used, because with such provisions the machine will never be required to run idle from one endof the road or cut to the other, or at least the necessity for wear and tear on the machine and waste of time by idle running will be greatly reduced. Furthermore, with a machine that can discharge at either side, regardless of which plow is being used, wagons can be loaded alternately at opposite sides of the machine, without slowing down or stopping the latter. Prior to my invention, and so far as I am now aware, no entirely satisfactory reversible or two-way machin?l of this character has ever been propose Objects of my invention are to provide a ditching and grading machine having simple and eflicient provisions for plowing up the soil on either side thereof, and for discharging the soil at either side therefrom, regardless of which plow is being used,

whereby the machine can be run or worked .1n either direction along one and the same side of the road or out upon which the machine is being operated; to provide a ditching and grading machine in which the elevator is adapted to have its lower or receiving end swung laterally from one plow to the other, and in which one plow can be raised out of the ground while the other plow is in use; to provide a ditching and grading machine in which .the elevator is adjustable laterally, so that it is adapted to receive the soil from either one of the two plows, and in which the conveying apparatus is employed for receiving the soil from the upper end of the elevator and for discharging the same from either side of the machine, regardless of which plow is in use; to provide a reversible ditching and grading machine in which a single conveyer can be moved or adjusted endwise, and in a direction transversely of the linevof travel, for the purpose of discharging the soil at either side of the machine; to providea ditching and grading machine in which the conveying apparatus by which the soil is discharged from the machine can be reversed at will for the purpose of delivering the soil at either side of the machine, whereby wagons can be loaded alternately at opposite sides of the machine, without the necessity of slowing down or stopping the same; and to provide the machine. Fig. 2 is a similar view show- 7 rear end with afoot-board or operating plat certaindetails' and features of improvement and combinations tending to increase the general efficiency and serviceability of a machine of this particular character.

To the foregoing and other useful ends, my invention consists in matters hereinafter described and claimed, and illustrated in the accompanying drawings, in -which Figure 1 is a plan of a ditching and grading machine embodying the principles of my invention, showing the elevator swung over to the plow at the right hand side of ing the elevator swung over to the iplow' at the left hand side of the machine. Fig.3 is a rear elevation of the machine shown in Fig.1. Fig. 4k is a side elevation of the machine shown in Fig. 1, showing the left hand side of the machine. Fig. 5 is a rear elevation of the machine shown in Fig. 2. Fig. Gis'an enlarged cross section of the machine on line 66 in Fig. 4. Fig. 7 is a rear elevation,:partly in section, o'f the driving and reversingmechanism, the section being taken online 7 7 of Fig.8. Fig. 8 is a side elevation of the mechanism shown in Fig. 7, certain portions being broken away for con-' venience of illustration. r p

Asthus illustrated, it will be seen that the body frameA can be of any suitable construction, and is preferably provided at its forward end with'a' drivers seat a, and at its form a, whereby "the operations of the'various portions of the machine maybe controlled by an attendant. The forward supporting wheels 1 can be arranged in any suitable manner, and the rear supporting wheels a are .preferab1y positioned some distance ahead ofthe foot-board or platform a in the manner shown. The plow beams Band C are provided with suitable plows or implements, and are propelled by push bars 5 and c, which'latter have their rear ends swingingly mounted on the outer ends of the rear axle (1 whereby the saidplows are pushed rather than pulled. The left hand plow, for example, has the forward end of the beam B supported by an operating: chain b and a spring b and the rear end of said beam is supported by an operating chain If. The chain b isconnected' with the beam through the medium of a spring 5 while the chain 6 is connected with the beam through the medium of a sheave or pulley b. The chain b runs over a sheave or pulley on the frame of the machine, whlle the chain 6 runs over a sheave or pulley b on the frame, and is also attached to the frame at 6 in the manner illustrated. The chain 6 is wound upon and operated by a hand shaft mounted above the platform or foot-board al while the chain b is wound upon a hand wheel shaft 5". It will be seen that these two handl same tothe lower end of the elevator. upper end of the elevator, which is of any clearly in Fig." 7.

wheel shafts are associated together and easily operated by the attendant standing onthe foot-board or platfornra ,'whereby the low beam B and its attached plow or lar to those previously described. It will be seen that the said plow beams have their plows positioned to throw their soil inwardly, so that either plow may deliver the soil to the lower end of the longitudinally disposed elevator D. A hand'wheelshaft d extends transversely of the machine, at a point above the lower and forward end of the elevator, and ispr'ovided with a'hand wheel d at one end, and a loosely mounted drum or sleeve (l2 at the other end, the latter operated by a similar hand wheel 0Z A chaind is wound on the drum or sleeve 0F, and is arranged to travel over the sheaves or pulleys d d d at points between its upper and lower ends. The lower end of said chain is attached to the lower end of said elevator. The chain d has its upper end wound on the hand wheel shaft d and travels over the sheaves or pulleys d 01 d, before having its other end attached to the said elevator. It will be seen that thesaid sheaves or pulleys d d, are mounted on the frame or body of the machine, whereas the sheaves or pulleys (Z d d (Z are mounted on the plow beams.

A transverse rod or movable way (Z is supported by chains d, which have their upper ends wound on the transverse hand wheel shaft D in the manner shown. tSupporting chainsd are provided at their upper ends with wheels d adapted to travel on the said rod or way, and are secured at their lower ends to a bail al which latter .issecured to the said elevator. In this waythe said elevator can be raised and lowered by rotation of the hand wheel shaft D and can be adjusted to one side or the other by the hand wheels d d whereby the soil can be caused to coiiperate with either plow. When one plow is in use, the other is raised, and in this way the machine can plow or tear 'up the soil at either side and deliver the The suitable construction, is supported by a hlnge or pivotal bearing 0!, which latter is associated'with bevel gearing (Z and the drive shaft al in the manner shown more A vertical shaft d is mounted 1n'a .bearlng ti, and connectssaid bevel gearing witha lower bevel gear d.

which latter engages a'bevel gear d on the axle a of the rear supporting wheels. A sprocket gearing 03 connects the gearing d with the upper end of the elevator,

' whereby the latter is driven by the forward motion of the machine.

The pivotal bearing (Z permits the lower end of the elevator to swing up and down, and the shaft d provides a swivel bearing about which the forward end of the elevator can swing from one side to the other. It will be seen that these adjustments of the elevator are accomplished without disturbing the power transmitting connection between the same and the rear aXle. The soil when ele vated by the said elevator is discharged onto a transversely arranged conveyer E, which latter is provided on its under side with rollers e, adapted to travel on transverse ways or tracks 6 in the manner illustrated. Said transversely arranged conveyer is adapted for endwise bodily movement in either direction, so that the soil may be discharged on either side of the machine. This is preferably accomplished through the medium of operating chains 6 6 which latter are caused to travel over sheaves or pulleys 6*, 6 for the chain 6 through the medium of a hand shaft 6 which operates said chain, it being observed that the pulley 6* is secured to the conveyer, and that the sheave or pulley e is on the upright frame of the machine. Said hand wheel shaft 6 is also mounted in suitable bearings on the said frame, and is disposed longitudinally of the machine. The chain 6 is caused to travel over a pulley e on the conveyer, and over a pulley 6 on the frame of the machine, and is operated by a hand wheel shaft a, disposed longitudinally of the machine and mounted in suitable bearings on the frame thereof. With this arrangement, the chains at one side of the machine can be wound up while the chains at the other side of the machine are being paid out, and in this way the conveyer E can be moved to either side of the machine, according to which one of the two plows is in use. The said conveyer is driven by a belt or sprocket chain 6 which travels over sheaves or pulleys e 6 on the frame of the machine, in the manner shown. Said sprocket chain is driven by a sprocket e on the longitudinally disposed shaft 6 which latter is provided with a bevel gear 6 adapted to engage the bevel pinions e 6 on the axle a, in the manner illustrated. A clutch e operated by a hand lever 6 is employed for connecting the bevel gears 6 a", with the said axle, and may be thrown from one side to the other, so as to reverse the motion of the power transmitting connection thus provided. In this way the belt or apron of the conveyer E can be caused to travel. in either direction, so as to discharge the soil at either end thereof, according to the kind of work being done. It will be seen that the hand lever 6 can be easily operated by the attendant standing on the platform a which is also true of the hand wheel shafts e 6 whereby the operator has the machine under complete control.

It will be seen that the chains 0 6 are attached to the body frame at one end, and wound upon their respective hand wheel shafts at the other end. It will be understood that all of said hand wheel shafts are provided with suitable ratchet devices, for preventing back rotation thereof, which ratchet devices can be easily thrown out of engagement when the hand wheel shafts are to be operated for unwinding the chains. It will also be understood that the said machine can be provided with suitable draft appliances at its forward end whereby it can be operated either by horses or a traction engine. The belts or aprons of the elevator A and the conveyer E, as well as the plows or implements F, can be of any suitable, known or approved character.

From the foregoing it will be seen that I provide a novel and highly efficient construction, which permits the ditching and grading machine to be operated in either direction, and which permits the soil to be thrown to the right or the left, according to requirements, and regardless of which plow is being used. The machine can be operated along one side of a road or cut, and-then turned around and drawn back along the same side of the road or cut, throwing the dirt in the same direction each time. Also, the machine can be started along either side of a road or cut and caused to operate at either side thereof, and then turned around and brought back on either side of the said road or out. In this way much time is saved, as the machine will not .be compelled to travel idle as much as heretofore, and the work to be done will be accomplished in considerably less time. Also, with this arrangement, wagons can be loaded alternately at opposite sides of the machine, without slowing down or stopping the same, thus saving time in this respect. With the exception of the raising and lowering of the elevator, the entire machine is controllable from the rear end thereof, and by an attendant standing on the foot-board or platform in the rear of the conveyer.

It will be seen that the plows are hung outside of the lines of the wheels, and that said plows are spaced apart and mounted for independent raising and lowering. The longitudinally disposed elevator is shiftable from one plow to the other, and is mounted at its rear end upon a pivot or swivel. With this arrangement, either side of the machine can be driven close to the side of a cut or bank, and the soil can be thrown from either side of the machine, regardless of which low is brought into action.
