vfacilitate the laying of the tile in any soft ground which is subject to cave-in, and also in ground containing quiclrsand; whereby,

' the tile may be pushed into and held in place and a contiguous joint made with the next adjoining tile, and so held, even in the event of cave-in. 1 Y

The invention has for a further object a tile placing means controlled and actuated by pneumatic pressure means, thefluid lpressure for which isv supplied by a suitable pump arranged to be operated-from the motor mechanism of the excavating machine.

A further object of the invention is to provide an elevating means, associated with the tile placing means, which is adapted to| remove from the tile placing attachment, water and slush draining into said attachment, whereby a' comparatively dry place may be maintained forthe operator, and filling in prevented, until after the tile sections have been properly covered. y

rhat the invention may be Vmorefullyunderstood, reference is had to the accompanying drawings forming a part of this description, showing a preferred embodiment of the invention, in which z# Fig. 1 is a side elevation, partly in section,

Ditching or excavating lmachines of the wheeled type are well known to those skilledV in the art, and I therefore have only shown so much of such a. 'machine as will be necessary to illustrate the' connection of' my tile laying attachment thereto. VThe. digging" wheelof such machines is designated by the dotted lines 1 provided with' thev annular toothed rims 2v engagedV by Vdriving gear wheels 3, carried on a shaft 1, operated in any suit-able manner from themotive power carried by the machine, These. machines have arsupporting framework, which in this Y instance' is designated by the beams 5` (5 and 7, and it is to these beams tha-tiny tile'laying attachment,to be described, is suitably'connected.

' Ordinarily the ditches dugby the ditching Y or excavating machines, in which the drain tile is laid, is in ground where the danger of a cave-in o f the side walls Vof lthe ditch is not to `be seriously considered,A and .the tile" may be laid by the lw'orlnnenwith little orno difficulty and without the need of such an attachment asherein shown and described. However, ground is oftenV encountered in which the ditches are dug which is veryV muddy, ,or which Vcontains consider-able quicksand. Ineither event the laying of the tile rduring the digging of theditches or thereafter, is done with considerabledifli-'i culty, by reason of the fact, thatcave-ins willv occur beto-re the tile sections can be 'properlyvr 'laid and placed in juxtaposition to each` other, and' lincidents are on record, 'Wliere, during the laying of the tile sections jinsuch ground, cave-inshave occurred, and the',` pressure has vbeen, sol greatupon the tile sections that they were separated: axially, the ground? forcing the l.tile sections apart and entering' p a v f los icc'

therebetween, destroying communication be- .tween the said tile sections. My attachment aims to overcome the possibility of the cavein of the walls ofthe ditches during the placing of the tile sections, and maires it possible to so place the said sections in jui:- taposition to each other thatthey are retained in place and cave-ins will have no material elfect thereon to separate the saine. Further, when `ground is encountered containing quiclrsand, my attachment provides for the introduction gravel into the dit-ch on which the tile sections may be llaid and forcoveringand surrounding said tile sec.- tions with ojravel to protect the same against ,caving in of the walls of the ditch.

The attachment includes a housingl made up ofthe opposite side walls 3, connected by the curved bottom Awall 9, the Vfront curved wall and therear vertical Awall 10a, the latter stopping short at the bottoni of the housing as at 11 to provide an opening in the rear end of the housing,` as shown at the bottoni in Figs. 1 and 2, thru which yare pushed the tile sections A, as will be more fully explained. The forward ends fof the side walls 3 and the front wall 10 are arranged vtohave a suitable detachable 1 connection with the beams 7 forn'iinga part of Vthe frame work of the machine, whereby the'housingvis drawn by the machine and thru the ditch cut by the ditching wheel 1.

In other words, the housing trails the ditchi ing` Ywheel with thecurved bottom 9 of the housing, preferably moving on the bottoni of the ditch and conforming to the croes section thereof, see Figs. 3 and "lhe said housing, as will be `observed looking at the cross-sectional views 3V and 5 constitutes a movable curbing' to retain the walls of the ditch during the placing` of the tile, the tile placing means being operably carried within Ythe housing, as Vwill be explained.

rlfhe tile placing` or .pushing` means, coni* vprises preferably a carriage 12 mounted on rollers 13 adapted .to'travel on rails. 14.-

the curved bottoni 9 of thehousing,

secured to andi extendii'ig longitudinally of carriage havingl attached thereto a head plate 15 acting,v as the placer or pusher for the tile sections, in i' a n'ianner to be described. PivotallyV connected,.oentrally to Y and at the forward end of the carriage 12,

"and preferably immediately. inv the rear of the plate 15, is a curved bar orfrod 18, which at its forward end is pivotally connected to a slightly curved link 1'?, and said lini at its forward end is pivotally connected to the. lower endof a piston? rod.18,connected Vto a piston (not shown) reciprocally can, lried in the cylinderV 19. l preferably pro-Y vide anti-friction rollersQOfand 21, respecjitively, the pointsof connection fthe fbarorrod 16 with tl'ierhnir 1.7, and ofthe linki 17 with the piston'xrod- 13, andlsaid said `pivoted to the main y "at 3f( to permit the waeel and the tile placrollers travel between spaced guides 22 and 23 arranged within a housing 24 disposed within the housing attachment and preferably at or near the forward end thereof, an upstanding transverse partition 25 in the main housing' constituting a part of the front wall of the housing 2li, so that the operative parts of the tile placing` and holding means are confined within the housing and within the walls 8, 9, 10a and 25 ooijisjtitutinp` -tlie main housing, see Fig. 1. rilhe ma ii portion of the housing 24 is arranged in a preferably upstanding` position and has a lower curved end opening into the main housing' of the attachment. This is true also of the guides 22 andV 23 which are coni'ined within the housing 24e, andthe respective guides and 23 separated to allow for the up a.d down and angular movement of the bar or rod 16 and the link 1'? As shown, the carriage 12 and placer oi' pusher 15 thereon are adapted to have horizontal movement only, and this move-Y sition in the machine. Therefore, the housing and guides 22 and 23 are so constructed, and the bar or rod 16 and link 17 designed, that the verticalV .reciprocal movement'imparted to thepiston-rod 18 is transformed into a horizontal movement.

To the upper end of the cylinder 19 is connected a pipe 26 and to the lower-end of said cylinder isY connectedV a pipe 27, both of which connect with a 'preferably four way valve coupling 23, provided with a valve handle To said Vvalve coupling is also connected a pipe 31. .In Fig. 6 the pipe 30 connectsdirect with a lpressure tanl 32 and pipe 33 connects the pressure tanl with a suitable pump 34:. rThis pump in turn is connected by a pipe 35 with a supply or reservoir tank 3o to which the pipe 3l, isy connected.

l prefer to inount the entireliuid pres-r sure system and its operative parts on the tures thereof, as this frame carries the eX- eavatii wheel and its operating parts and' Sii vi ou Yin)V also the tile placing` attachment and its.

pai

ing attachii'ient to be raised and lowered. vit i locate a shaft carrying a large bevelV gear wheel 38 with which'meshes the diainetrically opposed driving` and Vdriven bevel. gear .pinions 39 and L10,' the former carried on a driving` shaft leading tothe engine, not-shown, vor other motive means Vofthe excavator, and the latterY carried on, Y

- suitably journaled on the frainea shaft work described. The: shaft Ltliru suitable rlhe entire iranieworleis usuallyl .no of the escavator Y iso connecting gearing 42 actuatesV a shaft 43 thru .suitable connecting gearing 44 operates the pump 34, see Fig. 6.

The operation of placing a tile by 4the means described, is as follows :-It.is understood of course that the excavator is moved forward a suit-able distance, the wheel l cutting a ditch and the dirt removed to one side thereof.` When the machine has progressed a sufficient distance, a signal is given the operator and the machine is stopped, the tile placing ,andv holding means being approximately inthe position shown in Fig. 2. A tile Als handed the attendant within vthe main housing who lowers it intol position on the bottom 9 between the rails i4. This done, the valve handle v29 is manipulated tof` permit iiuid to flow into the upper end of the cylinder to operate the V'piston rod 18link 17. bar or rod 16 and the carriage l2 moving the plate' l5 into engagement with the tile A moving it into position and in juxtaposition to a preceding tile section, if one has been placed, and holding the tile section in suoli position.V This position of the parts may be maintained whether the machine isthen moved forward orV not; it being intended of course to hold the tile after the signal has been given to advance the machine, so as to insure that' there shall be no separation of the tile sections. rilhe attendant has full control of the pneumatic pressure means for operating the tile placing means, thruthe handle 29 and may reverse the movement of the fluid at will' to operate and retract'such placing means.`

The tile as placed are moved out thru the opening ll, at the rear of the housing, it

Y being Vunderstood that the Vtile placing mechanism is ynot only designed to 1engage and movetlie tile sections into position, one

against the other, to provide a complete and perfect drain, but that such mechanism also serves to hold the tile sections, one against the other to prevent loose joints, and that such holding operation continues during the stoppage Vof the machine and during the` forward movement of the machine following each placing operation; thereby obviat-l ing any and all danger of the tiles separating.

The attachment, as now described, is useful when the machine is operatinoin muddy ground void of quiclrsand conditions, but which is subject to cave-in, the side walls 8 of the housing acting as a curbing to retain `Jthe side walls of the ditch and permit the placing of thel tile' sections Aon the bottom of the ditch, the said tile sections being pushed out thru the opening in the rea-r end vof the said housing, as will be under'- stood. Y l Y 'y Y To provide for the laying of the tile sections in'ditches where quicl'rsand is encountered,l preferably employ a chute 45 formed with a hopper 46 at its upper end and with a semicirculairearwardly extendingshield 47 at its lower end. This chutey is-preferably arranged forV detachable connectionwitliH and protruding thru the opening in the rear,V

end of the housing, part ofthe tile within the housing vand part wit-hout, but protectedy byV theshield 47 of the chute. Vllere it will be seen that the gravel has formed .a bed for the said section of tile, and covers all of that portion` protruding without the housing and has spread within the housing almost to the forward end of the tile section. yit this `point anew tile section is 'placed so as to. be moved in juxtaposition to ythe tile section lying part Within andpart without the lhousing, and when the new section has been soV placed the forward n'iovement of the machine will allow the gravel discharged from the chute to spread over and around the newly Vplaced tilesection in the manner shown in connection with' thc last Vplaced tilesection` in Fig. 2. it is to be understood that the placing ofy the said tile sections whennsiiig the chutef45 is so timed that a bedof gravel is provided for the said sections, -as shown in Fig. 2, so as the machine moves forwardly there can be no tipping of thesaid tilesections which would dislodge .the same and prevent axial alignment of the Anent and succeeding tile sections. y Y

I have provided'for the removal of water and slush from the inainhousing of the at-A y tachmeiit, which may enter thehousing thru or around the tile, due to'any causes whatice y soever.r There areV conditions of soil,'where if no provision is made for the removal of 110 any such water and slush, sooner or'later` the housing would lill to auth av point that placing and laying of the tile would be prevented, and conditions wouldbe such that anV attendant. or operator could not stay in the housing of theattachment. Such a means,

preferably comprises a bucketelevator, in-Y cluding an'endless conveying cha-in 48 hav-k ing connected thereto, vat intervals, buclrets` or cups 49..' VSaid chain is driven by :i sprocket wheel 50 on a shaft 5l and also passesaround an idler sprocket wheel `52 on a shaft 53. This elevatori-ispreferably enclosed within the housing24 discharging` therefrom at the upper endthereof thru a" discharge spout 54, and said elevator. s'tiadlV dles the guides 22 and 23 inainanner seen in Fig. 4, the housing 24 being open 'at its lower end, as at 55, see Figsn lV and 9, toper;`
