- the lower end of the post 9 is enlarged, and a central vertical slot formed in the body of the boss, so as to produce a fork having double parallel walls that are rounded on the edges, the space intervening between the jaws of the bifurcated head being of such relative width to the thickness of the front axle as to neatly fit onto it.
- the shape of the front axle of the ditcher is shown in Fig. 5, and it will be noticed that a bolt, 34, extends through the center of the bifnrcated lower end of the swivel-post 9, and also a corresponding point iu the side wall of axle a, when it is in proper position. 3y the method of construction just described a limited universal movement of the axle ai and the wheels C' is effected.
- the frame A is stifiened longitudinally by the truss-braces D2, that are attached by their ends c c2 to the under side of the frame A.
- the parallel links c c are jointed to the bent truss-rods D2 at proper supporting-points to brace the frame A, to which these links are bolted by their upper ends.
- two parallel string-pieces, D are secured in place by the curved vertical bars O, and also by perforated enlargements that are placed on the rear driving-axlci.
- the bars O are also util ized for another purpose, that will be explained in its proper connection.
- the string-pieces or bars D are located at equal distances outside the vertical plane of the upper frame, A', and as the curved bars O are attached to the inside surface of said frame, the continuation of bars O that project below the frame have bosses extending laterally and outwardly at their lower extremities to attach to the sides of horizontal bars D at points h. (See Fig. 1.)
- the platforms k Upon the top face of the bars D, on each side of the machine, are securely attached the platforms k. These are horizontal on their top faces and of such a length in relation to the space that intervenes between the front and rear wheels of the apparatus as to form a clearance at their front ends to permit a proper swing movement of the front pair of wheels upon the pivotal center of the axle, that is necessary to turn the machine in any desired direction when in use.
- the pieces D are projected to the rear of the iirebox of the boiler A a sufiicient distance to afford support to a platform, a', that is placed thereon and properly secured thereto. This is for the accommodation of the engineer7 who controls the movement and operation of the mechanism, both as a locomotive and a ditching-machine.

AMOS BOUCHER, OF WHITE HOUSE, OHIO.
DRAIN-TILE-LAYING MACHINE.
SPECIFICATION forming part of Letters Patent No. 365,428, dated June 28, 1Ei87.
Application filed October 2G, 1886. Serial No. 217,248. {No model.)
To @ZZ whom it may concern.-
Be it known that I, AMos BOUCHER, of White House, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Drain-Tilc-Laying 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.
This invention relates to draintilelaying machines.
The object of the invention is to produce a self propelling and operating device that will cut a ditch of a suitable desired width and depth to receive different sizes of drain-tile, place-the tile properly in the ditch, and, if wanted, then cover the tile, the several operations being performed continuously and at one time; also, if necessary, to permit tile laying or the covering of same to be deferred and* simply a ditch be produced and the laying and covering operations be conducted subsequently, either together or separately, as may be desired.
With these ends in view my invention con; sists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 represents a side elevation of the machine.
Fig. 2 is a side elevation lof the opposite side of the device with the one driving-wheel removed. Fig. 3 is a plan view of the apparatus. Fig. 4 is a rear end elevation of the machine. Fig. 5 is a front end elevation in perspective. Fig. 6 is an elevation in longif l tudinal section, taken on the line a: rv, Fig. 3,
toshow the ditching mechanism. Fig. 7 `is a vertical transverse section of the ditching and tile-conveying n1echanism,taken on center line y y, Fig. 3. Fig. 8 is a detached view of the scraper blades and immediately attached frame-Work and operating mechanism.
Referring to the drawings by letter, A represents a horizontal steam-generator of a class known as the locomotive Jdre-box boiler.77
This is made of proper dimensions to providev an adequate supply of steam; and to facilitate draft, and thus quicken generation of steam, without the-use of a high smoke or draft stack,
a blower or steam-pipe of proper size is introduced into the smokebox S', that is formed in the front end of boiler A. A water-gage, steam-gage, try-cocks, and other necessary fittings to afford safety and facilitate the use of the boiler are provided; and as these are well known adjunets to all properly constructed boilers, a more detailed description is not necessary. y
lThe boiler A is mounted upon a frame, A', composed of two parallel string-pieces of iron or other suitable material. These are placed a sufiicientdistance apart to permit the cylindrical portion of the boiler A to be properly supported thereon, a saddle-piece, N, made to conform to the curvature of the cylindrical sheet of said boiler, being rigidly affixed in position on the frame at the front end of the boiler, as shown in Fig. l. The rear ends of the squared bars of the frame-A are rigidly secured to the front end of the rire-box B by bolts or rivets; and it will be observed that this method of securing the frame and boiler at but one end will permit expansion and contraction of both the shell and frame without hinderance, as such longitudinal limited movement is permitted by the sliding contact had by the boiler in the supporting cradle-bar N. The frame-pieces A are extended a proper distance forwardly. (See Fig. l.) Immediately in front of the throat-wall or front plate of the tire-box B', and parallel to it, the axle a2 is placed in suitable boxes that are secured to the supporting-frame A. The wheels C are rigidly attached to the ends of axle said axle being made of sufficient length to project beyond the outside of the frame-pieces A a limited distance, for a purpose that will hereinafter be shown.
At a point near the front extremity of the frame A a cap-plate, 7, is secured thereon, of suitable thickness and of a material to insure proper stability. Beneath this plate 7 another plate, y8, of same thickness, but of less width, is placed, to bear upon the under face of the frame A, and these two plates are secured together by bolts or other suitable means, or may be integral with the frame A'.
. Centrally beneath t-he plates 7 and Sis placed a suitably-formed and perforated plate of brass or otherproper metal. This is secu red in place,
and is designed to receive as a supportingbox the swivel-post 9. (See Fig. 1.) This is a bolt of proper length, of cylindrical form in the body, that is made to fit neatly the orice in the plate just mentioned, so that it can be revolved in it and, passing through the top plate, 7, be extended vertically. A cap-plate, 11, securely affixed to the top of the vertical parallel pieces 10 12, forms therewith a top bearing for the swivel-post 9, which centrally pcrforates it, and is held in position by a capnnt, 13, that rests on plate 1l. The lower end of the post 9 is enlarged, and a central vertical slot formed in the body of the boss, so as to produce a fork having double parallel walls that are rounded on the edges, the space intervening between the jaws of the bifurcated head being of such relative width to the thickness of the front axle as to neatly fit onto it. The shape of the front axle of the ditcher is shown in Fig. 5, and it will be noticed that a bolt, 34, extends through the center of the bifnrcated lower end of the swivel-post 9, and also a corresponding point iu the side wall of axle a, when it is in proper position. 3y the method of construction just described a limited universal movement of the axle ai and the wheels C' is effected. The frame A is stifiened longitudinally by the truss-braces D2, that are attached by their ends c c2 to the under side of the frame A. The parallel links c c are jointed to the bent truss-rods D2 at proper supporting-points to brace the frame A, to which these links are bolted by their upper ends.
At a short distance below the plane of the horizontal portion of the truss-braces D3 two parallel string-pieces, D, are secured in place by the curved vertical bars O, and also by perforated enlargements that are placed on the rear driving-axlci. The bars O are also util ized for another purpose, that will be explained in its proper connection. The string-pieces or bars D are located at equal distances outside the vertical plane of the upper frame, A', and as the curved bars O are attached to the inside surface of said frame, the continuation of bars O that project below the frame have bosses extending laterally and outwardly at their lower extremities to attach to the sides of horizontal bars D at points h. (See Fig. 1.)
Upon the top face of the bars D, on each side of the machine, are securely attached the platforms k. These are horizontal on their top faces and of such a length in relation to the space that intervenes between the front and rear wheels of the apparatus as to form a clearance at their front ends to permit a proper swing movement of the front pair of wheels upon the pivotal center of the axle, that is necessary to turn the machine in any desired direction when in use.
The pieces D are projected to the rear of the iirebox of the boiler A a sufiicient distance to afford support to a platform, a', that is placed thereon and properly secured thereto. This is for the accommodation of the engineer7 who controls the movement and operation of the mechanism, both as a locomotive and a ditching-machine.
Upon the platform a are placed the boxes A". They are located on each side of the platform, and are designed to contain water and fuel for the boiler-snpply. At the rear end of the watertank, located upon the left side of the platform a and securely affixed in a vertical position thereto, the supporting-frame for the steering-gear is placed. This is composed of two upright pieces, f/Z, and a cappiecc, y, firmly bolted or otherwise secured in position thereon. An upright shaft, B', atitslower end is boxed onto the frame D, so as to be properly supported in a manner to permit rotative movement ofsamc. lts upper extremity is similarly secured to the cap-picce (/f, andthe end that is made to project above the supporting-box g* is made to fit a perforation madcin the toothed sector g5. cylinder, 14, out with a coarse thread, so as to form a wornrgear, is meshed, the worm-barrel beingjournaled at the ends to be held in position by properly-formed lugs that project n pwardly from the cap-plate y.
In a slot or opening cut through the crosspiece D"of the frame D theV-grooved pulleywheel H is located. This wheel is firmly secured in place upon the upright shaft B at a point just above the Abox h2, that supports the lower end of shaft.
A belt, chain, or wire rope, Hi', preferably the latter, is placed on the V-channeled pulley, and rests therein at a point about the center of the length of the belt. The free ends of the latter are extended forwardly and horizontally till they meet the front axle of the machine, to which they are afiixed, the belt or wire rope being made sufficiently taut to transmit motion of pulley H to the axle a with precision. It is evident that the operation of the crank N will communicate the rotary movement of the worm-barrel li to the sector y, and thus, through the pulley H, give directive or steering movement to the front axle and wheels moiinted thereon.
At a point in the rear of the front wheels of the apparatus two upright metallic pieces, S, are erected vertical to the frame A', upon which they are rigidly bolted or otherwise secured. Stout braces b are placed as a side support at the front faces of the uprights. These braces are bolted or riveted by their ends to the uprights S and horizontal frame A. The pieces S are connected at their upper terminations by the crossbar o?, that secures them in parallel position and in the same vcrtical plane. These uprights are designed to maintain in proper place the ditch-excavating mechanism.
It is necessary for the proper action of the excavating machinery that a vertical and longitudinal adjustment forsame be provided, that should be under the control of the operator on the platform at the rear "of the boiler. To accomplish this a guide-frame is provided.
Into the latter a short This frame is composed of two similarlyformed plates, M, th at are rigidly held a proper distance apartby shouldered cross-braces 16 tended through the upright standard 12, so as tubular shield M2.
to receive theworm-wheels U U. These wheels are made of same diameter, and the shafts on which they are mounted are a sufficient distance apart to permit the vertical shaft a' to be located between said wheels, together with the screw-th readed barrel thatis rigidly affixed thereon, the threaded part being so situated in relation to the axial centers of the wheels U U as to mesh into the teeth cut in the peripheries of both, and thus actuate them.
At a point near the vertical center of 'the plates M, and on the rear -edges of same', is rigidly attached the upright metallic semi- This is made ofsuitable thickness to give the necessary stiffness and ofa diameter proportioned to that of the ditchexcavator.
The latter is constructed of suitable metai, and is given a regular auger-twistA in the body of same, the impinging cutter end being screw-pointed. It is-essential that this vertical screw-formed excavator M' be made of-such material as to secure requisite strength to resist lateral or torsional strains that are incurred in its operation. The auger-bit portion is made so as to permit its removal at will and different sizes ot' same substituted.
The semicircnlar metallic shield or case M2 is made to conform tothe diameter of the twisted excavator-blade M', so as to act as a rear support, and also assist the lifting of the excavated material, by forming a dirt chamber in the rear of the excavatorscrew.
The screw M' should be made of hardened steel, preferably, and polished, so as to transport vertically the material excavated with as little frictional action as possible. In order to cut the clay or stiff earth in which the tiles are to belaid, a thin spiral'blade, M",'provided do effective work, the forward cuttingedges of the shield assisting the operation.
The cylindrical short shaft, to which the auger excavator-blade M' is adjustably secured, is'held rotatively in a journal-box, and there is also a shouldered support formed integrally in the wall of the shield M2, at a point above the upper termination of the twisted body of the excavator M', through which the cylindrical portion just described is inserted and held in rotative position. It is prevented from vertical displacement by collars or shoulders formed on its body that impinge on the surface of the bearing formed for the purpose in the shield M. Onto the upper end of the excavator M'a miter gear-wheel, N', of suitable size, is keyed or otherwise fastened. This bevel-pinion N' meshes with a similar wheel, M5, that is supported in place by a cross-shaft, M6, being boxed removably onto the vertical Wall-pieces M.
There is a collar plate or box, N", so secured transversely below the pinion lo the side plates, M, as to permit the shoulder or abutting face of the pinion N' to bear and revolve upon its upper surface. The plates M are pivotally connected by studbolts to diagonal braeebarsPX- These bars have perforations formed at their extremities, and the lower pair have their free ends mounted on a transverse shaft that is held by its ends in journalboxes secured beneath the frame-pieces A', the position of this shaft-connection being near the forward end of t-he boiler A, just below the smoke-box of same. The lower pair of parallel bars, X, are curved somewhat, edgewise, as shown iu Figs. kl and 2. The upper pair of bars, P, are connected firmly by the cross-braces e fv, and have their inner ends attached to a cross shaft, V', that is bracketmounted upon the boiler A at a point immediately in the rearof the stack E.
Upon the extremity of the shaft V', that projects on the right side of the machine, a miter gear-wheehV", is mounted, so as to meshwith a corresponding pinion, V, that is secured to the forward end of the shaft d. This round shaft extends toward the front of the fire-box B, and is supported in position by fixed brackets d' d, that are riveted in place to the boilershell Aand fire-box B. The forward bracket, d', is extended down the perpendicular side of the tire-box, and isslotted to retain a vertically-movable journal-box, d, through which the shaft d passes.
The box di* can be held at any desired point by the adjustment of a set-screw, d4, that is inserted in the edge of the bracket d2. To have a bearing with its point upon the box d, the rod or shaft d terminates in a handle, a, at its free end above the platform a. A threaded barrel, d, is keyed fast upon the shaft d, ata proper point above the center of the drivingaxle a2, and there is placed upon this axle a? a worm-wheel, I, that is-of a proper diameter to'give the requisite speed to the shaft cl, to
which it is, when necessary, connected bymeansof the adjustment of said shaft and its supporting-box d3 in the bracket d', so as to cause the screw-threaded barrel d to mesh into said wheel l; and it is intended that said wheel should be keyed onto the shaft or axle a2, so as to' receive motion therefrom. `The end of the shaft V' is projected beyond the IOO IIO
ill.
supportingbracket a proper length to receive the sprocket-wheel V5 outside of the bevelpinion V2, situated on same shaft. This wheel V5 is connected by a strong endless squarelinked chain, V, to a large sprocket-wheel, I, that is placed on the axle a", between its inner face and the worm-wheel I on the same axle. The shaft V is also made to project on the opposite or left side of the machine a suitable distance beyond its supporting-bracket to permit the adjustment on same of the sprocket-wheel V7. This in turn is connected to the smaller sprocket-wheel, P2, on the crossshaft M by an endless chain, M, and it will be remembered that a direct connection of the shaft lllG is effected with the vertical excavator The sprocket-wheel VT is also made to act as a pitman-wheel for the direct attachment of the reciprocating steam-engine F by means of the connecting-rod Z, that attaches by one of its ends to the engine, and the opposite end to a crank-pin afiixed in the outer face of the sprocket-wheel Vl, so as to obtain propel' throw or crank action.
From the foregoing description of the relative working parts it will be evident that the rotative movement of the wheel V7 by the steam-engine F will cause the excavating-drill and cutter lll to revolve with a speed proportional to the motion of the engine and the relative size of the gearing. The progressive movement of the apparatus on its wheels is effected by the chain-connection of the shaft V on the right side to the driving-axle a2, and thus permit the reciprocating motion of the engine F to act on the driving-wheels. The engine F is preferably constructed with valvegear that will allow a reverse motion to be given thereto, and so permit a retrograde movement of the entire device on its wheels.
In operating the machine for excavation of ditches in soils that are very compact and difficult to intrench, it is of advantage to give the critter Ma rapid rotation and to have the forward motion of the machine so reduced as to give a limited slow feed ofthe revolving tool against the vertical breast of the ditch. To accomplish this gradation of the joint rotary andprogressive movements, the small sprocketwheel V5 on the right end of shaft V is looscned by removing its retaining-key or setscrew. The worm gear-wheel I and the spiralthread barrel d are then brought into operative connection bylowering the shaft d. This is secured in place by rigid adjustment of the box d3. The driving-pinion V will now rotate the shaft (Land conseqnentl y, by its connection with the worm-wheel on the axle a2, cause a comparatively slow movement forward of`the excavator.
It will be noticed that a .vertical shaft, M, is located with its lower end stepped into a bracket-box, Mm, that is affixed to the frame D on the right side ofthe apparatus,at a point close to handle a of the rod d. This shaft has a V-grooved wheel, o, of proper diametrical size, mounted on itsupper end. This wheel is furnished with a handle, M, to revolve the shaft MH. A11 endless belt, s s, of proper strength, placed on the grooved wheel o, is eX- tended forward to the grooved wheel T,tl1at is mounted on the shaft u at the front end of the frame A. Two supporting grooved pulleys, 24 25, that carry the belt ss and preventswagging of same,are'attached, so as to revolve on their centers, to the right edge of uprights S, the belt s s being made suflicientl y taut to give effective movement to the pulley T when the handle on pulley o is rotated.
The parts to which the wheel T is connected move the segmental racks R, so as to elevate or depress them, and in this manner cause the drilling-excavator M to be raised or lowered to cut a ditch of more or less depth, as may be desired. The side bars, O, by bearing against the parallel bars l? X, hold the same from side-play while the raising or lowering operation just described is in progress.
Directly inthe rear of the cutter-shield lll, between it and the boiler-front end, and in the same vertical plane with the said shield, the curved tile-conveyer M is placed. The upper end is of such a height as to be accessible from the platforms 7s on either side of the machine, and it is hinged at that point t0 the rear surface of the case M'l to permit a limited vcrtical movement of the tubular conveyer' Ml", so that it will adjust itself by gravity to the varying undulations of the bottom of the ditch in which it rests, its free end MT being extended a proper distance rearwardly, so as to afford a horizontal delivery-pipe, as shown in Fig. 1. rhe size ofthe caliber of this tube and its form and degree of curvature must be so proportioned as to afford an easy and assured descent of the drai utile. This feed opY eration of the tiles is effected by an operator standing upon either platform 7c and placing the tile consecutively into the tube or conveyer Mm. This conveyer or guide-tube can be constructed having the section ofthe wall of same made to fit any desired sizes and shapes ofthe tile, so that they can be delivered into the ditch in regular successive order with their ends held in proper contact bythe gravity of the descending column.
It will be noticed thatv there are vertical parallel guide-wings V made to project from each side of the shield llI2 rearward. These are made of sufficient strength to be stable, and are intended to hold the tile-conveyer M in position laterally, while at the same time free vertical play of the tube or trough is permitted by the hinged connection at its upper end.
After the tiles are properly deposited in the ditch the ditch-covering apparatus comes into use. This consists of two blades, made preferably of iron to insure strength and capability of durable service. The first shovel, D', is adjustably secured to the frame D, or the platform k of same, that is located on the right side of the boiler A. A vertical lever with spaced holes t" in its side permits this end of IOO ' section and permit effective action as a scraper.
y The rear end is produced to form a bar that extends diagonally across the open ditch and connects pivotally to a boss on the top edge of the rear scraper, D3. This latter piece is made similar to D in the shape of the blade,
. by the operation of the rock-shaft j and arm j',
and is also adjust-ably held in place by a ver- `tical slide-bar, b, that works in proper retaining-slides affixed to the inner side of the longitudinal frame-piece D, that is located on the left side ofl thel ditching-machine. The rear end ofthe scraper D3 extendsin a diagonal line from the inside of the frame D on left side, asjuststated, to a point immediately below the standard-,frame of the steering-gear that is erected on the engineers platform, as shown at Gr in Fig. et of the drawings. At thispoint it is pivotally connected to an upright link` bar, at. This has its upper end secured by a movable joint at a3 to a vibrating lever, a?, that passes through a slot in standard g of the frame of the steering-gear, and is therein pivotally boxed to permit the lever a2 to be vibrated vertically, andso move the connected end of f the scraper G in a, corresponding manner. A further means of adjustment of both the scrapers simultaneously is provided that is connected to the scraper D3 at a point near `itslongitudinal center by a vertically-descending link or carrier, j?. The rock-shaftj is oscillated so as to raise or lower both of the Scrapers together by a lever, kl, attached to` its inner end, that is in a convenient position for the handof the engineer.
It should be stated that this device is ini tended to propel itself over ordinary roads to places where itis to be used.` For this reason the provision of two separate means of effecting progressive movement are provided, the quicker speed being preferably employed `for travel, and the reduced speed for ditching and tile-laying work. It is obvious that the steeringgear hereinbefore described willv give proper control of the movement of the machine and permit the subterrane drainage-pipe to be laid in any desired curvature, or diverging from a straight line, as occasion may require. Should it be desirable to simply excavate the `ditch without placing tile in same, the tubular conveyer can be disconnectedat its hinged juncture by removal Of the fulcrumpin in same, and the Scrapers so elevated as to clear the excavated earth at sides of the ditch. This will effect the object sought..
Evidently many minor changes may be made in the mechanical details herein described without departure from the spirit of my invention.. I therefore reserve the right t-o make such slight modifications as will facilitate constrution of the parts and be within the scope of my claims.
