Application filed February 24, 1908. Serial No. 417,327.

To all whom it may concern:

Be it known that I, ALBERT G. SCHERER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Means for Packing Nesting Pipe, of which the following is a specification.

As is well known in the trade, nesting pipe comprises blanks of sheet metal of the same lengths as sections of pipe are usually made. These blanks are formed into cylinders, and

the longitudinal meeting edges are provided with facilities, usually each edge is bent into reverse engaging hooks, for engaging each other, so that when it is desired to use one of the blanks the edges may be engaged and a section of pipe will thereby be provided. The principal advantage of nesting pipe is that, the longitudinal edges of the blanks being free of each other, a number of the blanks may be inserted inside of each other, or nested, for storage and shipment, and, when so nested, a great economy of space is secured.

It is evident that when the blanks are nested, as above described, the inner blanks tend to expand the outer. Heretofore, as far as I am aware, it has been the universal practice to crate nests of pipe for shipment, and it has been my experience that the expanding tendency of the nest often results in the breaking of the crate and consequent damage to the package.

My invention relates to the provision of facilities for utilizing the expanding tendencies of the nest to form a substantial and neat package, which will entirely do away with the necessity of crating. I attain these objects by the mechanism illustrated in the accompanying drawings, in which,-

Figure l is a perspective view of a section or blank of nesting pipe with my new tying means in assembly therewith. Fig. 2 is a View of a nest of pipe, some of the sections being broken away to show how the beading upon the respective sections engages to prevent a relative slipping of the blanks. Fig. 3 is a cross-sectional view of a section or blank of nesting pipe with my new tying means in assembly therewit Similar reference numerals refer to similar parts throughout the several views.

The reference numeral 1 designates a blank or section of pipe' adapted to be nested, having upon its longitudinal meeting edges the oppositely turned bends or hooks, 2 and 3. These blanks or sections are further provided upon one end with longitudinal corrugations, 4, to reduce the diameter of the end of the section so as to make it easy to insert the reduced end into the next adjacent section, and just back of the longitudinal corrugations they are provided with one circumferential corrugation or bead, 5, to prevent the entering section from slipping too far into the outer or entered section.

In nesting and packing the sections for shipment, herein described, I place all of the beaded ends at one end of the package, as clearly shown in Fig. 2, so that the beads, 5, upon the inner sections will project into the beads upon the adjacent outer sections thereby preventing any relative slipping between the sections of a nest or package.

To bind the nest or package firmly together I provide the piece ofsheet metal or tie, 6, the longitudinal edges of which are provided with facilities, in this case oppositely turned edges or hooks, and 8, for engaging the oppositely turned bends or hooks, 2 and 3, upon the longitudinal meeting edges of a blank or section of nesting pipe. This tie, 6, of course, is made of suitable length for the number of sections it is desired to pack in a single nest. If it is desired to pack, say, twenty five sections in a single nest the tie will be shorter than if it were desired to pack fifty sections in a single nest.

In making a package or nest with my new means the tie, 6, is first adjusted so that its turned or hooked edges, 7 and 8, engage the turned or hooked edges, 2 andB, of a blank or section of nesting pipe at about their central portions, as shown in the several figures, and other sections are successive y rolled into smaller diameters and inserted, one after the other and one into the oher, inside of the section so held by the tie. The

expansion of the inserted sections firmly 1 firmly locking the package as a mg compressed into smaller diameter so as to release the tie, 6, until the nesting sections have been removed. One way of unpacking such a nest is to proceed in the re edges are out of engagement with the edges of the outer section, when the sections may be removed, one by one, from the outside of the nest.

In nests packed as herein described, the

walls of the several sections or blanks lie so closely together as to reinforce and strengthen the walls of the outer section thereby doing away with the liability of denting and bending the sections in shipment. Crates cannot be made to exactly fit the nests, and the sections, during shipment, are often ammed about in the space or play which is necessarily left and injured. With my nest, on the other hand, there is no play and this source of injury is excluded. My nest is much smaller, as well as much firmer, than a crated package, and will not only storemore in a given space but is particularly advantageous in long hard shipments, and in exporting by steamer where the dimensions and solidity of the packages are of great importance.

After the nest has been assembled, I sometimes inclose it in a suitable Wrapper, 9, usually paper or burlap, as shown in Fig. 2, to prevent-superficial scratching or the soil- I ing or Wetting of the sections during shipment or storage. The wrapper, 9, however, is not necessary, and when it is not used the tie piece, 6, can be stenciled with the shipping address without defacing any of the sections thereby doing away with tags which are often torn off with this variety of goods.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

sections whereof are provided with hooks upon their longitudinal edges, a tie piece having hooks upon two opposite edges adapted to engage the hooks upon one of said sections, the other sections of said nest being disposed and permitted to expand within the section whose edges are secured by said tie piece.

2. A nest of sections of nesting pipe, the sections whereof are each provided with a circumferential corrugation and with hooks upon their longitudinal edges, a tie piece having hooks engaging the hooks upon the edges of one of said sections, the several other sections being successively disposed inside the tied section and inside each other and permitted to expand with their successive corrugations extending into and interlocking with each other.

' In testimony whereof I have hereunto set my hand in the presence of two witnesses.
