K 'jhpnnow TILE.

To all whom it may consent:

Belt :known that I; Joiix M. Ca'mmai', a citizen of the Un'ited' St ates of America,

and a resident of -i\larshal ltown, Marshall county, Iowa, ha ve invented certain new and useful Improvements to Hollow Tiles, of

which the following is a specification.

. My invention relates to improvements in hollow tile, and the object of my invention is to provide hollow cylindrical tile with suitable connecting means so contrived that when such tile are secured together they may he turned relative to each other in one direction for adjustment without separating, while it turned. in an opposite direction they may be readily separated, thus fitting them especially for use as drain tile, and when desired such tilingmay be perforated at suit able locations to facilitate the process of drainage tliereinto. This object I have accomplishcd by the means which are hereinafter fully described and claimed, and which are illustrated in the accompanyingdrawings, in which: i

Figure 1 is a side elevation of one end of a drain tile showing it removablyconnected in my improved manner to another tile, the latter being in central longitudinal section, and both tiles being broken away intermediate of their lengths. Fig. 2 is a perspective view of one end of a tile showing the construction of the receiving eiid thereof, the rest of the tile being broken away.-

Fig. 3 is a side elevation of a tile united removably at each end in my improved manner with other tiles, the latter beingintermediately broken away.

Similar characters of reference designate the same parts throughout the several views.

The hollow tiles A and B are shown as being formed with a pluralityof annular corrugations, but this is not an essential feature of my invention, since the tile may be shaped as plain cylinders ifdcsircd, but my invention resides in the manner of coupling the tiles. I have also shown 'in Fig. 3, the tiles provided with a plurality of orilices f, which become useful when the tiles are formed of metal and used for drainage. However, the orifices may be dispensed with, not being an essential part of my invention, when the tile is used as a conduit rather than for drainage purposes.

.\s shown in Fig. 1, the received end of' each tile is supplied with one turnof a spiral corrugation b at its end, and 1f desired the corrugation may be less than a single turn. However, this turn of spiral. corrugation'b is adapted tobe received into a similar spiral corrugation of one turn or less on the receiving end of'the abutting tile, as shown at c in said figure. The receiving shown, conducing to ease in assemblin The character (1 designates a broad ammthe tile B,- and as shown in Fig. 3, the spiral corrugation 0' opens into this closed annular corrugation (l from-the side, the annular corrugatiou' (I being disposed about the tile B so as to conform itself to the adjacent corrti'gation '0 as nearly as'possihle, that is, is set somewhat obliquely aboutthe tite, to conduee to the ready leading of .the' one or spiral corrugation into the other or annular corrugation. The corrugatioi'i (l is also made of considerable breadth, so as to wholly receive the spiral corrugation b writlxin itand permit of the corrugation i) being turned about within itwithout bind ing. The object of this manner of connection between the tiles 'A and B is to permit any tile to be turned in one direction relative coming disconnected or on the other hand so tightly bound thereto as to be prevented from freely turning. \Vhen the short spiral corrugation b has been received wholly into the broad annular corrugation d, it may be turned in the same direction as that in which it was introduced without binding or becoming detached, and when the tile is perforated at f. as shown in Fig. 3, for irrigating or drainage purposes, the separate tiles may be turned and adjusted with reference to each 'other as desired so as to bring the orifices f into locations desired. \Yhen it is necessary requisite to reverse the movement, turning back the spiral corrugation b so that, when a slight pull'is added, its end enters the way provided by the other spiral corrugation 0, when it may be removed with but a sin le turn from the latter. The broad annu ar corru ation d therefore serves as a holding trough or channel for the short spiral corrugation b, and when the latter 15 within the trough so provided, it cannot escape theretion in which it entered the trough. lfhe corrugation (I being broad gives sco e for the turning therein, and a provision orexcorrugationc takes at a feather edge as to the other connected tile without-either befrom when continuously turned in the direcno,
