DIRECT-DRAFT ROAD AND DITCHING MACHINE.

SPECIFICATION forming part of Letters'Patent No. 365,847, dated July 5, 1887.

Application filed March 15, 1887. Serial No. 230.955.

- To all whom; it may concern.-

Beit known that I, HENRY CLARKE MOORE, a citizen of the United States, residing atTama City, in the county of Tama and State of Iowa, have invented certain new and useful Improvements in Direct-Draft Road and Ditching Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improvements in road and ditching machines; and it consists in the construction and combination of parts, which will be particularly hereinafter described and claimed.

One object of my invention is to provide a road and v ditching machine which combines reversibility and adj list-ability of the scraper part with a direct application of the draft power to said scraper, and, further, to increase its effectiveness and convenience in handling.

A further object of my invention is to pro vide a road and ditching machine which will be simple and effectivein its construction and operation, easily operated, and readily understood.

I attain these objects by the mechanism illustrated in the accompanying drawings, wherein the same letters and figures of reference indi cate the same or corresponding parts in the several views, and in which- Figure l is a side elevation of myimproved machine, showing the scraper set for work, the dotted lines showing it in position for ditching. Fig. 2 is a top plan view of the ma chine, showing its wasp-shaped frame, and also the scraper in reversed position in dotted lines. Fig. 3 is a detail view in perspective of the scraper and its attachments to the main draftbar, the scraper being shown at an angle with one portion thereof below the surface of the ground in full lines and as resting on the surface of the ground in dotted lines. Fig. 4. is a detail view in side elevation of one of the traversing carriages and of a portion of the main frame. Figs. 5 and 6 are detail views in end elevation of the channeled sides of the main frame, the traversing-frame provided with the ratchet-teeth, the standards, lever- (No model.)

flllCllllllS, guy-braces, and trucks or rollers. Fig. 7 is a detail View in end elevation of the scraper and one of the swivel-connections for parts for connecting the same to the scraper.

Fig. 10 represents a rear view of the scraper, having attached thereto the removable leveling attachment provided with the sledshaped shoe. Fig. 11 is a front end elevation of the scraper, the leveling attachment, and the sled runner-shaped gaging-shoe. Fig. 12 isa modi fied form of draft-bar and the devices in construction therewith.

A indicates the side bars of the supportingframe of the machine, which are constructed of channeled or I steel, or other suitable material, and formed of a shape similar to that of a wasp-as, for instance, the portions just to the rear of the front axle may be taken as the head of the wasp; then follow the shoulders, then gradual convergence to the point forming the waist, and then divergence which forms the tail; also, said sidesare raised or formed to be in higher planes between the front and rear axles than they are just over said axles, for purposes hereinafter stated. These side bars are mounted at their ends upon axles A, provided with wheels A and the rear portions thereof are united by aplatform, A, upon which the operator stands and controls the operation of the machine. In the front and rear portions of the said bars A, and secured to the inner side thereof at each of their ends, are crossbeams A A The forward beam, A", has ears or lugs a secured thereto,;in which a lever, B, extending longitudinally and centrally of the machine, is pivotally mounted. verBhas a hook secured thereto, to which one end of a chain, b, is adjustably attached. The lower portion of said chain is rigidly attached to a loop or eye, I), secured to the top of the main draft-beam 0. Another chain, b connects with said loop and passes up to a grabhook in the front of crossbar A, to which it is adj ustably secured for sustaining the weight The forward end of the le while adjusting the chain I) from the end of lever B. The draft-beam O is pivotally secured to the rear end of the draft-iron,which extends over the front axle, and is held in connection therewith by the king-bolt passing therethrough.

To the rear end of the draft-beam O a draft and sway bar, D, is pivoted at its center, and to the ends of the latter the draft-bars E E are pivoted, and thence extend backward and in the rear of the scraper F, to which they are flexibly and removably secured. On the upper portion of the scraper swivel-eyes ff are secured, through which clevises f f pass, in

which the draft-bars E E are placed and firmly clamped by the clevis caps and nuts.

' On the lower portion and near each end of the scraper F brackets f f are bolted, and through these the ends of the draft-bars E E pass, said brackets being of such construction as to allow the said bars to move into the positions required when the scraper is reversed, and thereby prevent binding or clamping between the ends of said bars and the scraper. Screw-bolts f 3 f are secured in the ends of the bars E E, one on each side of each bracket ff, and in such a manner as not to bind the said bars, the said bolts only acting to retain the scraper in connection with the bars E E and prevent said scraper from changing its elevation should the nuts of the clevisesff become loose.

To the back upper portion of the scraper, near each end, are secured brackets f 4 f having swivel-eyesfifi, to which are secured the lower ends of the bifurcated rodsG G. .These rods have loops at their lower ends fitting in the swivel-eyesf f Loopsf f are secured to the brackets f 4 f 4 for the attachment of the chainf The lower looped ends of the rods G G are connected to the scraper F, and their upper ends are bifurcated and extend upward outside of the main frameone on each side thereof.

In the bifurcations of said rods the long levers H H are pivotally secured and rendered adjustable by pins or bolts and a series of holes in said rods and levers,whereby the leverage may be lengthened orshortened. The ends of levers H H are fulcrumed on the bolts h h, between the upper ends of the front uprights, it, of the traversing carriages on frames I I, said uprights extending above and below the sidebars, A A, on both sides thereof. The rear uprights, z" i, of said frames also extend below the side bars on each side thereof.

1 I represent the traversing frames or carriages, one being arranged on each of the side bars of the machine, and each is constructed of of two front uprights, Maud two rear uprights, r" 2'. One of the rear uprights, i i, is curved forwardlyand extended upwardly above the side bars,A, where it is provided with ratchetteeth i on its inner side, and the other rear upright has attached thereto an upwardly and forwardly inclined bar, 2*. The purpose of 7 these inclined bars 1 i. is to revent too reat lateral movement of the long levers H and H as they areraised or loweredin adjusting the position of the scraper. These front and rear uprights of the traverse-frames are connected together by iron straps 2%, Fig. 4., which are forked at their ends and bolted to said uprights. The outer front uprights, it, extend downward, curve outward, and have secured thereto,or formed in one therewith,the iron or steel extension i i, having eyes i '5 the object being to form guy-braces for adjusting the chains. These front and rear uprights straddle the side bars of the frame and are bolted together above and below said side bars, the bolts being covered with pieces of gas-pipe for holding them solidly in'place and preventlinks i i", one of which'is shown in Fig. 5, to

which the traversing chain f is'secured.

At the center of the cross-bar A of the main frame is secured the shortyertical shaft j, which carries a sprocket-wheel above the same. On the rear side of said cross-bar A at its ends,and at the front side of the cross-bar A at its ends, are secured short vertical shafts carrying the pulleysj j j' j Around these pulleys the traversing or reversing chain f is moved, said pulleys being flanged at their lower ends or provided with thin disks of metal for holding said chainf in place. This traversing or reversing chain passes around the outside of the pulleys j j j 3' and inside of the sprocketwheel j, as shown in Fig. 2. said sprocket-wheel being also provided with a flange or thin metal disk for assisting in holding up said chain.

At the frontend of the scraper F the chain f is attached to a loop, f, which is secured to bracket f Said chain passes thence through a semicircular loop, 70, attached to the front side of-cross-bar A at its center; thence it passes down to another loop, f,on bracket f, at the rear end of the scraper F,and has slack enough to reach either of the two grabhooks A k k, in which it is attached when the machine is in operation. This chain is also allowed slack for the operator who is upon the frame to adjust the position of the scraper by pulling on said chainj .To secure the chain after the adjustment of the scraper, the grab-hooks k 70 on the sides of the frame are used, and also the grab-hooks k k", located at each endof the cross-bar A, nearits lower edge and on its front side. Y

A curved loop, F, is affixed to the center of the scraper and rises above its upper edge.

coltershaped, as shown at n in Fig. 1, and

To a ring located. at the center of this loop are connected thetwo chains f 3 f which pass through the eyes i i at the ends of the guyoperator in reversing the scraper from the;

frame.

The draft-iron Z, to which the main draftbeam (J is connected, is placed immediately above the upper circular plate at the front end of the frame and securely bolted to the bolster.

The king-bolt passes through this draft-bar, and also through the lower draft-iron, Z, to which the team is attached. This lower iron passes rearward, curves over the axle-tree, and drops downward. To its upturned end is at tached a link of an extensible draft-chain, f. This chain is attached to the sway or draft bar D by passing through the eye m at the front end of the latter, and is adjustable to the desired length by a hook at its end. When the scraper and other parts are reversed, this chain f is transferred by the driver dr operator to the opposite endof the sway or trairerse bar and at tached to the other eye, 1%. Upright studs may be substituted at the ends of said bar in lieu of the eyes m m, if desired, as being more con venient for the removal of the chain. To either of these eyes m m at the ends of the traversebar one end of another chain, f, is attached in the same manner as the chain f, the other end being applied to any of the grab-hooksmm, secured to the standards over the front axle. In reversing the position or changing the angle of the scraper these chains f f are disconnected from the sway-bar, and the chain f, at tached to both ends of thescraper, is thrown out of connection with its eyes f 6 f In this operationreversingthe chain f drags through the loop k under the sprocket or chaiu-wheelj.

In readjusting the chains after reversing the length of thechains from the center of the scraper may require to be changed. The two front chains, f f, are only used when at very heavy work.

To accompany the machine two rudders are provided having different shapes, one being the other of a curved or sled-runner shape, as shown at n in Fig. 9. These rudders are interchangeable for working in different kinds of ground. They are formed from plates of steel doubled back and shaped to form a bolt hole, and are provided with recesses 72 11. communicating with said bolt-hole, as shown in Fig. 9. Alvertically-arranged bolt, n forms a pivot upon which the rudder may be turned or adjusted, said bolt passing through lugs n n of a bracket, n which is bolted to the back of the scraper at its center. The lugs a n may be fitted in the recesses n n at various heights, and secured by the bolt n thus providing for the adjustment of the rudder at different elevations.

To the back of the scraper, at its center, is secured a. curved bracket, 92, provided with ratchet-grooves on its inside. It is curved in the arc of a circle of which the pivotebolt n is the center, and extends around the rear portion of the rudder when the latter is in operative position. The ratchetgrooves permit of the upper back portion of the rudder being placed in either of them, and thus said rudder on the back of the scraper holds the latter in the line in which the team travels and lessens side strain on the wheels and frame.

In Fig. 8 is represented an extensible axletree, A, for the hind wheels of the vehicle. This axle-tree is bisected at its center and fitted in a sheath, 0, made of channel and angle steel plates, or of either of these forms of metal. The plates forming the sheath are rigidly con nected by collars 0 0, which pass around and rise above them and are firmly bolted to the sides A of the frame.

Projecting from the sides of the axle-tree sections, near their inner ends, are pins 0 0', against which the lower end of the removable hand-lever 0 impinges in moving the said sections to or from each other within the sheath for adjusting the length of the axle tree. Upon the upper sheath-plate rests the platform or bottom A upon which the operator stands. This platform has a line ofopenings formed in it above the pins 0 0, and abovethis line of openings is placed apiece of timber or plank having a line of openings registering with those first named. Passing through either of these openings is a removable handlever, 0, provided near its lower end with a pin projecting from its sides and resting on the edges of the openings in the piece of timber above the platform. Bolts 0 0 are passed through the platform,

the timber, and the upper sheath-plate, and are secured in any one of a series ofopenings formed along the upper surfaces of the axletree sections, so as to firmly hold said sections IIO at any point to which they have been adjusted.

By means of the extensibility of the axle-tree the wheels of the vehicle can be placed outside or inside of the ridge of earth formed at the delivery end of the scraper.

A modified form of the draft and sway bar D and the main draft-beam O is shown in Fig. 12 of the drawings. v is formed of two bars, D D", which. have the form of segments of circles having different centers and are rigidly connected at their ends.

The forward bar, D, is pivoted to the main draft'beam O, at the rear of the center 4 of a circle of which the rear bar, D, forms a segment. The rear end of the draft-beam Ois slotted at c, and beneath this portion of the This draft and sway bar.

bar is secured a slotted plate, 0; also, the rear curved bar. D", is formed with a series of holes, a. A key or bolt, 0, passes through these slotted portions and any one of the holes in said rear bar, whereby the draft-bars and the "road is prevented.

or leveler 1), near its lower edge, are the curved iron straps p p", which are provided with the At:

pivoted latches p p at their upperends. points corresponding to the ends of the scraper the plank p is provided on its rear side with pivoted bottoms p 10. When the leveling attachment is placed upon the main scraper, the lower edge of the latter rests between the straps p 1) and the rear side of the plank 10. Then when the straps p p are turned up and rest upon the back of the main scraper, near its ends, and the latches 19 19 are turned down upon its face, the leveling attachment and the main scraper are rigidly connected in vertical position, and then when the buttons 10 p, pivoted to the rearside of the plank,'are turned so as to project upon the back of the scraper, they hold the leveling attachment still more rigidly in position upon'the main scraper. A sled-runner-shaped shoe, 19 is pivotally attached to one end of the plank'p of the leveling attachment by means of eyebolts p", and is vertically adjustable by means of the nut 19 on the upper portionof said bolt and located in an aperture in the plank. By adjusting the nut p on the shank of the eyebolt p, which connects the sled-runner-shaped shoe p with the plank p of the leveling attachment, the depth to which the steel cutting-platep enters the ground is governed, and all gouging of the The attachment of this shoe to the scraper is readily effected, and when in position thereon the light operation I of leveling a road is effected with much greater speed and accuracy than can be done when the operator depends upon his judgment or eye for the perfection of the work. I

From the construction and arrangement of the parts thus described the following addi- --tional advantages will be evident to those skilled in the art. The draft sway-bar -D is not only pivoted at its center to the main draft-beam C, but the draft-bars E E are loosely pivoted to said draft sway-bar and are connected withthe scraper F by swivel-eyes,

. and the rods G G, connecting the operatinglevers H H with the scraper, are also connected by swivel-eyes. Theflex-ibility of these connections permits free horizontal and vertical movement ofsaid parts into various po sitions; also, by the employment of the draft sway-bar D, which is pivoted on the, main draft-beam G and carried by the chain 12, extending from the end of the lever B, thedraftbeams E E, connecting with the scraper,

may be materially shortened, so' as to effect close approachto the team, and thereby materially lessen. the weight on the operatinglevers; also, the jointed or pivoted connections of the draft parts contribute to and enlarge the variety of positions in which the-scraper may be placed, not only allowing it to be projected in all manner of ways outside of the frame, but permitting the angle of approach of its cutting-edge to the ground to be adj nsted; also, when the scraper F is raised by the rods G G and the levers H H, and the latter are placed in engagement with the ratchetteeth 2' on the sidesof the curved uprights i, the whole weight of the scraper and its connections rests uponfthe traversing frames I I, mounted upon the side bars of the supportingframe and uponthe sway-bar D, and when theadjustifng-chains f and f f, which are respectively attached to the scraper and swaybar and draft iron, are detached therefrom, I,

connecting with and supporting the scraper,

it has freedom of movement for any desired adjustment; also, when said scraper has reached the limit of the angle of adjustment that its supports will permit, the operator can increase its movement by pulling upon the chain f attached to its delivery end, said chain being then secured to one of the grabhooks k,attached to the sides of the frame opposite to the delivery end of the scraper; also, when the delivery end of the scraper is thus secured in the desired position, the chain f, at its middle,'w hich runs to the guy-brace i directly opposite, is adjusted to give such projection to the forward end of said scraper as .is desired. Then the chain f ,which runs rearward from the forward end of the scraper, and the chain f ,which runs to the front guy-brace i, are secured to their respective grab-hooks k and '5 so as to firmly holdthe scraper at work'when it is in the desired position. The

guy-braces i i are so arranged with respect to the scraper and the chains f and f ,which are attached to thecurved loop F at the center of said scraper, that the latter is always held in the exact position required, under whatever arrangement it is placed. The position of the front end of the-scraper may be changed by adjustment of both of the chains f f at the end of the sway-bar D.

On reference to Fig. 3 of the drawings, it will be evident that, the front I end 7 of the scraper is capableof adjustment, so as to penetrate the ground or enter a ditch to different depths and still beretained in rigid or fixed position when at work. To adjust the scraper for ditching,the lever H, as shown in Fig; -1, is lowered in the bifurcated upper end of the bar or rod G, which connects it with the IOO ratchet-teeth i or on the square shoulder 2" of .the curved uprights i. To drop the forward end of the scraper deeper into the ground, and still retain an easy cutting approach to its work, one or both of the chains b 1)", connecting with the opposite ends of lever B, are lengthened, thereby dropping the draft-beams and the draft sway-bar, and by the central connection of the main draft-beam O with the sway-bar a lower reach of the cutting-edge of the scraper into the ground is permitted by the downward play of the for- .ward end of the sway-bar, which could not be attained were the draft-beam E at the front end of the scraper directly connected with either of the front draft-irons, Z Z. The lower draft-iron Z permits lowering of the front end of the scraper deeper into a ditch and still retain its cutting approach to its work.

The dotted lines in Fig. 1 show a position in which the scraper may be placed by raising up the lever H, connecting by the rod G with the scraper at its delivery end, for the purpose of making or cleaning out narrow ditches.

The advantages in having the main frame of wasp-like shape at the waist are that it permits the rod G, connecting with the delivery end of the scraper, to extend under the frame and thus permit a more acute angle to be given to the scraper than it could have with a full width of frame, and by the breadth given to its rear end,which rests on the axle, greater steadiness and strength to resist twisting strains thereon is provided for; also,it affords more room for the operator and for ballasting the machine When at extremely heavy Work such as grubbing sage and making irrigating and other ditches; als0,when the main draftbeam 0 is raised by the leverB and its chain 1), and the scraper is placed at right angles to the frame, the front wheels of the vehicle can be turned in either direction with perfect freedom under the front raised portionsof the side bars of said frame Without interfering with the scraper or its connections.
