CONDUIT-PIPE.

SPECIFICATION forming part of Letters Patent No. 310,773, dated January 13, 1885.

Application filed June 13, 1884. (No model.)

.To ctZZ whom it may concern.-

Beit known that I, THEODOEE BAcMEIsTER, of Toulon, in the county of Stark, in the State of Illinois, have invented an Improved Conduit-Pipe; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this speci-` cation, in which like letters of reference refer to like parts, and in which- Figure l represents a side view of the invention; Fig. 2, a cross-section of the same; Fig. 3, a side view of a modified form of the invention; Fig. 4, a cross-section at x e in Fig. 3; Figs. 5 and 6, transverse sections of the two forms of pipe, showing modes of putting-the bands thereon.

The object of this invention is the adaptation of wooden piping to receive metal strengthening-bands and permit them to be tightened about the same.

My invention consists, essentially, of a pipe having its exterior diameter alternately increasing and diminishing regularly from end to end, whereby encompassing me? al bands may be driven from the smaller to the larger parts of said tube.

In thedrawings, Arepresents the pipe, and B the bands surrounding the same. a a are the parts of larger diameter, and a athe parts of smaller diameter. In Fig. l the increase of diameter is equal on both sides of each contracted part a', while in Fig. 3 the increase is gradual at one side and sudden at the other. Of these two forms I design the latter to be that usual for wooden piping bored from the solid, while the first form is preferable for tubes made in sections.

In making pipes from solid timber it is a simple operation to turn them upon a lathe and form them with either sudden or gradual changes of diameter; but when making a pipe with separate strips or staves said staves have to be formed by means of a planer or sticker, and the grain of the wood and manner of working it forbid anything but gradual thickening and thinning of the sta-ves.

In putting together sectional piping all the staves but one are first inserted in the different bands B. Then, the bands lbeing at the depressed places of the staves, the l latter are spread outwardly until, between the first and last of the same, there is room for the last of the staves to be crowded in under the bands. Fig. 5 shows the staves spread apart in the bands to make room for the last one. When the pipes are formed from the solid,thebands B must be united when about the same. To

do this each band B is passed about the pipe being less than the greater diameters of said` pipe and greater than the lesser diameters of the same, substantially as and for the purpose specified.

2. A pipe, A, having its diameter alternately increasing and diminishing, substantially as set forth, in combination with metal bands B, for the purpose herein described.

3. In a conduit-pipe, a pipe, A, formed of several strips or staves, each of which has the alternate elevations and depressions a a, in combination with the metal bands B, as and for the purpose herein set forth.

In testimony that I claim the foregoing invention I have hereunto set Inyhand and seal this 9th day 0f J une, 1884.
