JAMES T. BRIEN AND THEODORE R. BRIEN, OF HOOSICK FALLS, NEW YORK, ASSIGNORS OF ONE-THIRD TO G. FRANK RISING, OF SAME PLACE.

SOlL-PlPE.

SPECIFICATION forming partof Letters Patent No. 518,583, dated April 24, 1894. Application filed August 31,1893. Serial No. 484.423. (No model.)

To all whom it may concern:

Be it known that we, JAMES T. BRIEN and THnoDoRE R. BRIEN, citizens of the United States, residing at Hoosick Falls, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Soil-Pipes, of 'which the following is a speciication.

Our invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a central 1ongitudinal section of then faucet end of a section of soil pipe, the spigot end being broken away for convenience in illustration. Figs. 2 and 3 are similar views showing our invention in modified forms. Fig. 4 is an end view showing the wrought-metal band before the pipe is cast upon it.

It is well known to those skilled in the art that joints formed in soil pipes must be made of a durable character, and sufficiently tight to prevent the escape of sewer gas therefrom. Such joints are usually formed by inserting the spigot end of one section in the hub, or enlarged portion formed on the faucet end, of another section,and calking the space between the walls of the spigot `and faucet ends of the pipe sections with lead forced therein by a cold chisel or similar tool subjected to the blows of a hammer. When the lead is properly calked to produce a gastight joint, the pressure upon the inclosing faucet-end is very great, being frequently sufficient to burst or crack the pipe. We have ascertained that the faucet end of the pipe can be sufficiently strengthened by casting the same upon a wrought-metal band. The wroughbmetal, being much more tenacious than the castmetal and being in close contact therewith, largely increases its power of resistance without increasing its bulk, thus eliminating the danger of leaky cracks. The band may be a wire, or in any desired form, and of any kind of metal having comparatively great tenacity.

Referring to the drawings, A#- represents a bandwhich iiares outwardly, as shown in Figs. 3 and et. The pipe B has its enlarged, or faucet end B'- cast upon the inner side of the band, as shown in Fig. 3. The band thus strengthens the pipe like a hoop and is anchored onto the pipe, so that it cannot be removed, by its inner thickened end A- produced by its beveled form.

In'Fig. 1, the band A2- is inclosed by the cast-iron which is cast upon both the exterior and interior surfaces of the band, which is anchored by the inner thickened end A3.

In Fig. 2, the band A4 is inclosed by the cast-iron cast upon its exterior surface, leaving the interior surface of the band exposed.

The exterior surface ofthe band is beveled to produce the inner thickened end A5 by which the band is anchored to the cast-iron.

The band may be provided with any known form of anchorage.

We are thus able to produce a new article of manufacture which not only eliminates the costly item of breakage, but insures a safer and more durable joint without increasing the bulk of the pipe. t

I-Ieretofore the workman has favored the weakness of the pipe at the expense of the efficiency of the lead packing to prevent leakage of gas.

With our improved pipe, the joints can be calked more quickly as well as more securely, because harder blows can be delivered with the calking-iron and hammer without fear of injury to the pipe.

By having the reinforcing band ilush with the castmetal and prominently exposed at the outer edge of the faucet-end of the pipe, as shown, glancing blows of the calking-iron or hammer will be received by the wroughtmetal band instead of by the cast metal of the pipe as heretofore to the great injury of the latter.

What we claim as new, and desire to secure by Letters Patent, is

1. A cast-iron soil-pipe having its faucetend cast upon an annular tenacious-metal In testimony whereof we have hereunto set band anchored and embedded in the castour hands this 22d day of June, 1893. metal, substantiall as described. 2.
