woooEN PIPE.

SPECIFICATION forming part of Letters Patent No. 359,590, dated March 22, 1887.

Application filed April 22, 188 Renewed February 10, 1887. Serial No. 227,180. (No model.)

To all whom it-may concern.-

Be it known that I, CHARLES P. ALLEN, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Wooden Pipes; and I do hereby 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.

This invention relates to hooped pipes made of wooden staves.

My improvement consists, first, in interlocking the staves at the crossjoints by a metallic tongue, and, secondly, of a metallic hoop composed of an approximately circular strapbolt and a coupling-shoe so combined that the hoops can be tightened around the pipe after it has been placed around the same.

In the annexed drawings, Figure 1 represents a side elevation of a portion ofniy improved wooden pipe. Fig. 2- represents a cross section thereof. Fig. 3 represents aside elevation of a wooden pipe in which the slaves are arranged to break joints. Fig. aillustrates the coupling-shoe in section and the ends of the strap-bolt in elevation. Fig. 5 represents a plan of the coiiplingshoc. Fig. 6 illustrates astave end, showing the metallic tongue seated in the groove of the same. Figs. 4 to 6 are drawn to a larger scale than Figs. 1 to 3.

The same letters of reference indicate identical parts in all the figures.

A groove, a, is cut in each cnd'of each stave A deep enough to permit the entrance of a metallic tongue, B, about half way, as shown in Fig. 6. The length of the metallic tongue is a little in excess of the width of the stave, so that the ends of the tongue may project a little from each side of the stave to enter the edges of the adjoining staves, as shown in Fig. 2, when two abutting stave ends are driven up.

The concealed metallic tongue will then interlock the abutting stave ends with the adjoining staves, and thus form an excellent crossjoint. The hoops are composed of an approximately circular strap-bolt, O, and a couplingshoe, D. The couplingshoe is engaged from opposite ends by the respective ends of the strap-bolt. To this end the coupling-shoe is constructed with a socket for the T-headed end of the strap-bolt, and with a reverse socket for the nutted end of the strap-b0lt, the construction of these sockets and the length of the strap-bolt being such, as shown in Fig. 4., that the end of the strap-bolt carrying the nut will overlap and hold in place the T-headed end thereof. The not affords the means for tightening the strap-bolt around the pipe to the necessary degree.

I claim as my invention 1. A hooped. pipe made of wooden staves which are interlocked at each cross-joint by a concealed metallic tongue seated in grooves in the abutting stave ends and projecting a little at'eacli side thereof into the edges of the ad joining staves, substantially as before set forth. 2. A pipe made of wooden staves hooped by hoops composed each of an approximately circular strap-bolt and a coupling-shoe which engages the head at one end of the strap-boltand the nut at the other end thereof.

3. A hoop composed of an approximately circular strap-bolt and a coupling-shoe, the

strap-bolt having a head at one end and a nut at the other end for engaging the couplingshoe from opposite ends, substantially as before set forth.

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

CHARLES P. ALLEN. Witnesses:

RICHARD HOLMES, JOHN G. ANDERsoN.
