8 Claims.

My invention relates to connecters for drain tiles and the like, and particularly to that type of connecter which will serve to align and support adjacent ends of tile sections against relative displacement, and prevent dirt from entering between the tile sections and clogging the same.

Drain tile of the type referred to is placed in trenches for the purpose of draining fiat or swampy land, and in other instances is connected 10 to septic tanks or other sources of sewage for the purpose of discharging the waste liquid into the earth over a wide area.

The tile sections or pipe sections are of various cross-sectional shapes, usually cylindrical, and are commonly of uniform diameter throughout their length, the sections having no belled ends such as provided on ordinary sewer tile. The tile sections are assembled with their ends in slightly spaced relation to permit exit of water from the go, pipes into the soil, or toadmit water from the soil into the pipe, depending, of course, upon whether the water is being conducted into the soil or whether the soil is being drained.

The spacing apart of the pipe sections at their ends permits the surrounding earth to fall into the space and cause clogging of the pipes. Varione means have heretofore been employed for overcoming this difiiculty. In some cases, one end of each section is made of half-bell form, which disposed uppermost when laying the pipe, and so placed that it will partially overlie the unbelled end of an adjacent section, but such pipe sections have to be specially made, at greater expense, and are otherwise objectionable. 35 Another scheme has consisted in placing a strip of tar paper over the upper side of the joint, but the paper deteriorates after a relatively short period of time and permits earth to fall into the tiles.

My invention has for some of its objects the provision of a connecter which can be cheaply made; easily installed; will be possessed of long life, and will permit adequate flow of water into or from the pipe sections; and one which will accommodate tile sections of various diameters and be firmly retained thereon.

Some of the forms which my invention may take are shown in the accompanying drawings wherein Figure 1 is a longitudinal sectional view of a portion of a drain tile installation; Fig. 2 is a view taken on the line 11-11 of Fig. 1; Fig. 3 is a side view showing another type of connecter; Fig. 4 is an end View thereof; Fig. 5 shows a modification of the connecter of Fig. 2; Fig. 6 is a longitudinal 55,- sectional View showing still another type of con- 1934, Serial No. 716,118

necter; Fig. 7 is a view taken on the line VIIVII of Fig. 6; Fig. 8 is a sectional plan view showing another manner of forming tile-spacer tabs, on the connecters; Fig. 9 is an end view of a different type of connecter; Fig. 10 is a view taken on the line XX of Fig. 9; Fig. 11 is an end view of another type of connecter; Fig. 12 is a View taken on the line XII-XII of Fig. 11; Fig. 13 shows a modification of the connecters of Figs. 9 and 11, and Fig. 14 is a view taken on the line XIVXIV of Fig. 13.

Referring first to Figs. 1 and 2, broken sections of drain tile of any suitable form are represented by the numerals B and 9. The sections 8 and 9 are, of course, placed with their adjacent ends in slightly spaced relation, and are encompassed by a connecter III which may be made of sheet metal that is preferably of non-corrodible material such as copper. The sheet metal can be oi very light weight, since no great strains are imposed upon it, and it will, therefore, not be excessively expensive.

The connecter may be formed of a metal strip which is cut away intermediate its ends to form a slot 1 I, through which water may flow. In forming the slots, tongues of metal I2 are permitted to remain, and are bent inwardly to form stop shoulders or spacer-tabs for the ends of the tile sections 8 and 9, so that said pipe ends can conveniently be positioned in proper relation to the slot H, and will be held in spaced relation to one another. For convenience in handling and shipping, the connecter bands may be shipped in a somewhat flattened condition and bent to conform to the cross-sectional form of the tile sections and joined at their longitudinal edges in the field. The upper or longitudinal edges of the band are bent to the form of hooks l3 and M, which are interengaged with one another, in order to hold the band in position. The connecter band will not only prevent dirt falling through from the upper sides of the pipes, but will serve to holdthe pipe sections in longitudinal alignment and against relative radial displacement, either vertically or horizontally.

Referring now to Figs. 3 and 4, I show a connecter band l5 which is of a. form somewhat similar to that of Figs. 1 and 2, but which is adapted to be used with tile sections of various diameters. The band l5 encircles drain tiles I6 and has inturned tongues l1 forming stop shoulders for spacing the tile sections. Elongated attaching straps l8 are provided at one end of the band l5. The straps may be formed integrally with the band by removing the metal intermediate the edges of the band, or separate straps may be suitably attached to the band by riveting or otherwise. Adjacent to its other end, the band is provided with slots l9 spaced along its edges. The straps l8 are passed through a pair of slots l9 and bent backwardly to hold the band in position.

By the provision of the elongated straps l8 and the spaced slots 19, the band can be employed with tile sections of various diameters and firmly held in position thereon, since it is only necessary for the straps to be inserted through the proper pair of slots is, to form a connecter of the required size for tiles of a given diameter.

In Fig. 5, I provide a connecter 20 that is similar to the connecter ID of Fig. 2, but wherein the ends of the connecter are bent radially outward to form wings 2! through which a clamping bolt 22 extends, the bolt being screwed into a nut 23, so as to draw the ends of the band toward one another.

In Figs. 6 and 7, still another form of connecter band is shown. This band 2% has its ends slitted to form a slot 25 and

tongues

26 and 21. The tongues 26 and 2'! can be soldered or riveted together, if desired, but are here shown as unfastened, and as having contact with one another only by reason of the inherent resiliency of the metal band, so that the ends of the band can be sprung apart slightly to permit convenient insertion of the pipe ends. Stop shoulders 28 are bent up at the ends of the slot 25 and function as spacing and aligning members for the pipe ends. It will be seen that the band can be sprung sufiiciently to accommodate tiles of various diameters.

In Fig. 8, I show another manner of forming stop shoulders for spacing the ends of the tile sections on connecters of any of the types heretofore described. Adjacent to each end of the drain slot in the connecter, the metal is suitably punched or cut, so as to form tongues of metal that are bent inwardly from opposite edges of the slot, forming laterally-spaced stop shoulders 30. The tongues of metal may be of such length that their inner ends can be bent to form hook-shape stops for receiving the ends of the tile sections.

Referring to Figs. 9 and 10, I provide a metal sheet 3|, preferably of non-corrodible material, which may be curved to form a connecter that only partially encircles drain tiles 32, and it, therefore, requires less metal than the connecters that encircle the tiles. Adjacent to its ends, the sheet 3| is cut from its edges inwardly to form tongues 33 that are bent inwardly, forming laterally-spaced stop tabs for spacing the ends of the tiles 32.

The inner ends of the tongues 33, as indicated at 35, are bent into parallelism with the plane of the sheet, for engaging the inner peripheral wall of the tiles, and serving thereby to hold the band firmly in position.

The connecters may be handled in a flat sheetlike condition, since the tongues at the ends thereof need not be bent to form attaching and spacing tabs until the connecters are curved to -conform to the curvature of the drain tiles and applied thereto. The tiles are slid endwise betweeen the body portion of the connecter 3| and the end portions 36 of the tongues 33, the inherent resiliency of the curved metal sheet serving to draw the ends of the tongues into engagement with the inner wall of the tiles. The connecters are disposed, of course, at the upper side of the drain tiles, so that entry of dirt and stones into i the tiles is prevented.

similar to the connecter of Figs. 9 and 10, is employed to protect tile sections 35. Near each end of the metal sheet, slots substantially equal in width to the thickness of the tile sections are formed in the edges of the sheet, thereby providing bar-like end portions 37 integrally connected by webs 38 to the body portion of the sheet.

When the connecter 35 is applied to the tiles 36, the end portions of the sheet are bent out of the plane of the sheet along the line of connection between the webs 38 and the body portion of the sheet.

With the sheet curved to conform to the curvature of the tiles, the ends of the tiles are slid endwise into the slots in the sheets and into abutting engagement with the edges of the webs 38, which serve to space the ends of the tiles properly. The bar-like end portions 31, of course, yieldably engage the inner walls of the tiles due to the resiliency of the curved metal sheet, thereby maintaining the connecter securely in position.

Figs. 13 and 14 show the application of a sheet metal connecter 40 to drain pipes 41. The connecter is provided with end portions of reduced width that are bent to form loops 42 for the reception of U-shaped attaching wires 43, the ends of the wires being bent outwardly for engaging the inner walls of the tiles to secure the connecter in position. The intermediate bent portions of the wires serve to space the ends of the tiles.

It will be understood that certain of the connecters need not be made of sheet metal, but can be formed of clay, concrete or, other suitable material.
