vided for the flow of water between the band i and the tiles to the joint between the tiles.

A further object is to provide a device for holdingthe adjacent ends of drain tiles in alignment comprising a band of flexible material adapted to overlap the joint between the tiles and provided with means on at least the surface thereof which contacts against the surfaces of the tiles for permitting the flow of water between the band and the tiles while holding the ends of such tiles in substantial alignment.

The above being among the objects of the present invention, the same consists in certain features of construction and combinations of parts to be hereinafter described with reference to the accompanying drawings,

and then claimed, having the above and other objects in view.

In the accompanying drawing which illustrates suitable embodiments of the present invention, and in which like numerals refer to like parts throughout the several views,-

Fig. 1 is a side elevation of the end portions of a pair of substantially abuttingdrain tiles, such ends being heldinialignment by a device of the present invention.

In the use of drain tiles it is a" frequent occurrence to find that theadjacent ends of the tiles are out of alignment, thus having permitted earth to enter the interior :0f the tiles and plug the same. When such condition has occurred, it is invariably necessary to dig up the tiles, clean them out and replace them, which operation entails considerable time, labor and expense. Such misalignment invariably occurs when tiles are first laid or shortly thereafter on account of'the earth not being properly tamped whereby upon back-filling or consequent settling of the earth the tiles move and get out oftheir respective aligned positions. It also, often oc-. curs that the tiles are not fitted together properly when laid with'the'result that anabnormal space is left betweenthe same-through way and eventually plug the tiles. v i a By the present invention we provide a device which eliminates misalignment'ofthe tiles and prevents the, earth from finding a free passage through the joints betweenjthe same. As illustrative of the present invention we show in the accompanying drawing a pair of'tiles 15 and 16 in axial alignment, and having their ends in substantially abutting relationship but spaced sufliciently fromieach other so that thejoint 17 between the same affords a passage for water from-theexterior to the interior of the tiles. Surrounding the ends of the tiles15 and 16 overthfe joint 17 in overlapping relationship respect thereto is a strip of material 18incorporati'ngthe present invention. I .7 1 f In the form shownin Figs. 1 to 5 ,'.inclu-.

sive, and in Fig. 8 theband' 18 is formed of a type of material similar to or thexsame as conventlonal roofing materlal having onesurface thereof covered with crushed stone,

ice

. crushed slate, gravel or like material 19 as best shown in Fig. 3. In the form shown in Figs. 1 to 4 inclusive, the band 18 is of a length substantially equal tothe circumference of the tiles and 16 and is placed about the same'over'the band 17 as indicated in Fig.1 with the surface provided with the 1na-.

terial 19 in contactwith the surface of the tiles as indicated in Fig, 2, the ends of the band 18 extending in-substantially contacting relationship and. being secured together by a'clip 20. As indicated in Figs. 1 and' l,

I the clip 20 is formed from sheet metal and bent into a U-shape, the ends of which are pointed, the bottom of; the U contacting aganst the surfaceof thetiles and the pointed endsprojecting up through the free: ends of theband 18 as indicated bydottedlines I '1 in Fig. 4, and that portion of the ends'which projects'through the band18 being bentrov'er as indicated. infu'll lines in Figs land 1 thereby securing the ends. of'theband [18 against separation. The material of the band 18 as s h'own in the above discussed figures is preferably of any conventional roofing Inaterial provided'withthe material 19 on one side thereof, such roofing material as a general r'ule'being made of acoarse grade. of paper treated with tar, asphalt or thelike, although it will be readily understood that a strip of fabric or metal similarly treated and j'lO provided with the material 19 on one surface thereof will equally serve the purposes of the present invention and is included therein. Such material asdescribed when'proper- 1y treated withtar, asphalt or similar-ma terial will withstand the deteriorating action v of the damp earth to which they are subject-: ed in the use as herein described for a period of from'15 to 30 years, depending upon the character of the soil'and the amountofmoisture'in the same. 1 I 7 In placing the band 18about the tileslo 5 and 16 in overlappingrelationshipto the A joint 15, it will be apparent that the band '18 ineff'ect forms asleeve in which the adj acent ends of the tiles 15 and 16 are socketed,'thus holding the tiles'in alignment, and at the same I i time the-material 19 disposed between the band 18andthe'adj acentsurfaces of the tiles 7 provides a multitude of passageways through which the water in the earth-surrounding the tiles may'find its way to the joint 17 and i thence into the'interior of the tiles and' be 7 on a substantiallyfirm bed of earth'and'in' axial alignmentwithfeach other. A band carried away.

' In pract1ce,the method employed in using the bandsof the present invention is as'follows-:jWhen'" the trench isdug, the tiles are laid endto end within the same, care prefer- "6O ably being taken to have the same positioned 18 is slipped over the j oint-17 between-each pair of tiles, the clip 20 ispla'ced between the free ends of the band and the ends of the band 18 are then forced down over the ends of the clip, thus forcing theends of' the clip throughthe ends of the band, and the clip that in the conventional manner of layingv tiles would give upon back-filling and allow the tiles .to become misalignechthe device of t the present invention will hold such ends in o alignmentin spiterof such fault of the bed below the tiles, and prevent lsuch'mis'alig'nment and consequent entranceiof earthinto the tiles. Y

Although we have shownin Figs. 1, 2 r

3 a .particularmethod of securing ends of the band 18, in, position over the jointj17 it will 7 be understood that the method shown is merely illustrative of any suitable manner of securing such ends together, and other means for holding the band 18 in place such as-il-- lustrated in Figs. ,5 and 8, or any other means I may be employed. 7 In Fig. 5 a simple method; of securing the ends of the band together is shown. In that figure the band -18'is made slightly longer than the circumference of the:

tiles, the ends beingoverlapped when the band is in place and asplit rivetsuch as 21 is driven through the overlapping portions of the band, the ends of the rivets spreading when driven against the tiles and holding the In Fig. 8 the band band securely in place. is positioned over the joint 17 and one or more wires 22 is extended around the same and twisted together thus holding theband 18 securely imposition. ,Other similar-means are readily suggested and maybe employed i when desired. 1

.In Figs. 6 and 7 amodifiedform of band is shown. In this modification the band. 23

-may be formed of the samematerial as-the band 18 but instead of being provided with the material 19 on one surface thereof, that surface is provided'with a series of grooves or corrugations 24 which may be molded, rolled". I

or otherwise formed in the one surface of the material to thereby provide'iwater passages.

in the. same manner thatthermaterialil9forms 5 water passages for the band-18.. The jband'l 23 may be secured in place in the samfe'manner- I ,as described in connection with the band .18, but wehave showna modifiedmanner of securing the same in place comprising one or more wires25 which are preferably molded tudin ally of the same, the wires25 projecting past the adjacent ends of theband andbeing twisted together as indicated" in' Fig. 7 to hold the-band in position.

Formal changes may" be made in the spe I or otherwiseformed within the band 18 lo'ngicific embodiment of the invention described without departing from the spirit. orsub:

stance of the broad invention, the scope of which is commensurate with the appended claims.
