THOMAS J. MILNER, OF DENVER, COLORADO.

CONDUIT.

SPECIFECATXON forming part of Letters Patent No. 701,214, dated May 27', 1902.

Application tiled April 6,1 901.

To all whom zit may concern:

Be it known that I, THOMAsJ. MILNER, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Conduits; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the figures of reference marked tl1ere on, which form a part of this specication.

My invention relates to improvements in conduits composed of sections of pipe formed from clay or other material and adapted for sewerage, drainage, and other purposes where conduits of this character may be employed or required.

My improvement consists in the means employed for connecting the pipe sections whereby the conduit is given great strength and durability, which is the object of the invention, all of which will now be described in detail, reference being made to the accompanying drawings, in which is illustrated an L, embodiment thereof.

In the drawings, Figure l is an elevation of my improved conduit. Fig. 2 is a longitudinal section of the same. Fig. 3 is a crosssection of the conduit shown on alarger scale. Fig. 4 is a section taken through one of the bands or rings located at the joints between the sections, shown on a larger scale. This section may be indicated by the line ctx, Fig. 3. Fig. 5 is a perspective view showing a portion of one of the rings or bands.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the sections of the conduit, which may be composed of clay or any other suitable material. Both extremities of the pipe-sections are formed plain, and bands or rings are employed at the joints between the sections. These bands are T- shaped in cross-section, being provided with an interiorly projecting circumferential tongue or ange 6,1ocated between the ends of the sections 5. The exposed part of the band is of sufficient width to overlap the adjacent sections at the joint. A packing 7, composed of any suitable material, is located Serial No. 54,723. (No model.)

between the bands and the adjacent extremities of the pipe-sections, the said packing extending around the tongue 6,wherebya tight joint is formed. This packing, as shown in the drawings, also overlaps the ends of the sections, being located underneath the body of the band.

Projecting eXteriorly from each band 6 are a number ot' lugs 6c, provided with openings for tie-rods 8, which are employed to connect the bands and lock the sections together to form a conduit of any desired length. As shown in the drawings, the bands are each provided with three lugs 6C, though it is evident that the invention is not limited to any precise number of lugs. Each of these lugs is provided with two openings adapted to receive the extremities of the tie-rods leading to the two adjacent bands, one on each side. These rods are secured by nutsapplied to their threaded extremities, whereby the sections may be securely clamped together.

An interior circumferential recess is preferably left between the sections around the inner periphery of the tongue 6 after the packing '7 is applied. This recess may be filled with cement 9 from the inside of the conduit, making the latter perfectly smooth on its interior surface.

The bands 6 are provided with exterior openings 6g, located on opposite sides of av .adapted to pass between the sections at each joint, a packing material located between the tongues and the sections and held in place by the band, and tie-rods connectingthebands.

2. A conduit composed of sections, bands or rings surrounding the conduit at the joints, and T-shaped in cross-section, an in terior circumferential tongue being formed ICO on the ring, adapted to pass between the ends ofthe sections, the body of the band overlapping the sections exteriorly,the band being provided with exteriorly-projecting, apertured lugs, and tie-rods attached to the lugs for connecting the conduit-sections.

3. A conduit composed of sections, bauds located at the end joints and provided with interiorly-projecting circumferential tongues located between the extremities of the sections, the exterior portions of the bands overlapping the sections, a packing cooperating with the bands to form a tight joint, a circular recess being left between the sections at the inner periphery of the tongue of the band, and a cement iilling for said recess.

4. A conduit composed of sections, a band or ring, T-shaped in cross-section located at the joints of the sections, the body of each band overlapping the section ends exteriorly and the tongue passing between the ends of the sections, the band being provided with exterior openings on opposite sides of the tongue, and a cavity being left between the band and the conduit into which molten metal or other packingmay be introduced through the said openings.

5. A band for sectional pipes or conduits, said band being T-shaped in cross-section whereby a circumferential tongue is formed on its inner periphery, its outer periphery having a plurality of apertured lugs.

In testimony whereof I afx my signature in presence of two witnesses.

THOMAS J. MlLNER.
