Outspinning the Spider: The Story of Wire and Wire Rope

In Short

John Kimberly Mumford’s 1921 industrial chronicle details the evolution of wire and wire rope, framing drawn metal as the invisible backbone of modern industrial life. The book traces the trade from ancient hammering techniques to modern precision drawing, focusing on the John A. Roebling’s Sons Company. It follows the development of wire ropes, the construction of suspension bridges like the Brooklyn Bridge, the massive production demands of World War I, and the creation of the company town of Roebling, New Jersey. It stands as a portrait of early twentieth-century American industrial ambition.

The Story

The narrative opens by establishing the early twentieth century as the "wire age," asserting that modern transportation, communication, and infrastructure rely entirely on drawn metal. Without wire, cities stall, communications collapse, and transit halts. The text contrasts ancient smiths who painstakingly hammered metal into crude shapes with modern wire drawers who reduce steel billets to filaments finer than human hair.

The book moves to the mid-nineteenth century, introducing civil engineer John A. Roebling. Seeing the limits of hemp rope, Roebling designs and manufactures wire rope to haul canal boats and haulways. He applies his invention to bridge building, proving its strength over the roaring waters of Niagara Gorge by flying a kite across the chasm to pull the initial guide wires into place. This success leads to longer spans, culminating in the Brooklyn Bridge. Mumford describes the engineering mechanics of these long spans, focusing on the thousands of continuous wires woven into massive cables to support suspended roadways.

The narrative shifts from bridge construction to the manufacturing process across the company's three major plants: the Trenton site, the Buckthorn plant, and the Kinkora works. The author takes the reader through the mill, step by step: red-hot steel billets pass at high speed through rolling mills, undergo acid baths to clear scale, receive lime coatings to neutralize acid, and endure long bakes to eliminate hydrogen. The text outlines specialized treatments, including copper wire drawing, asbestos insulation, asphalt coating, and the application of solid lead sheathings over multi-colored paper-wrapped telephone cables.

The book then details the mechanical principles of wire rope assembly. It explains how altering the direction and pitch of the twist—such as the "Lang lay"—balances strength against flexibility, while acknowledging that twisting wires into strands reduces the raw tensile capacity of individual wires under laboratory tests.

During World War I, the company transforms into a wartime supplier. The text lists massive production quotas: millions of feet of heavy rope for harbor submarine nets, millions of splices for artillery horse traces, aircraft strand, and field communication lines wrapped in tussah silk and rubber.

Finally, the narrative concludes in the company-built town of Roebling, New Jersey. Mumford describes the town’s layout, free water, company-run stores, bakery, and leisure facilities, framing the enterprise as a model of industrial stability designed to maintain a steady, contented labor force.

How It Unfolds

The dawn of wire The narrative establishes that drawn wire has replaced primitive vegetable fibers and heavy iron chains across human industry. It explains how centuries of slow trade craft gave way to precision drawing techniques capable of creating filaments finer than a spider’s web.

The suspension bridge breakthrough John A. Roebling introduces wire rope to structural engineering, overcoming widespread professional skepticism by building the Niagara Railway Suspension Bridge. He refines his methods on the Ohio River span before designing the Brooklyn Bridge.

Inside the roaring mills The text walks through the manufacturing floor, tracking how white-hot steel billets are whipped through high-speed rolls by skilled workers. The process continues through acid cleaning houses, baking ovens, and precision die-drawing rooms.

Engineering the cable and rope The author outlines the mechanics of stranding, showing how varying the twist and core composition adapts wire rope for specific tasks, from mine hoists to elevator cables. It details the testing methods used to verify tensile strength and load limits.

The wartime mobilization During World War I, production pivots to military manufacturing. The mills churn out harbor submarine defense nets, heavy artillery harness traces, aircraft rigging, and insulated field telephone lines under strict government inspection.

Life in the company city The book closes with an tour of Roebling, New Jersey, detailing its planned infrastructure, worker housing, civic amenities, and corporate management philosophy aimed at preventing labor disputes.

The People

• John A. Roebling: The pioneering engineer and industrialist who invents practical wire rope, founds the manufacturing company, and designs the Niagara and Brooklyn bridges to prove the strength of suspended wire structures.
• Washington A. Roebling: The son who carries out the construction of the Brooklyn Bridge after his father's death, directing the complex cable-spinning operations and completing the span.
• The wire mill workers: The skilled laborers who maneuver red-hot steel rods through high-speed rolling mills in thirty-minute shifts and splice millions of feet of wire rope for industrial and military use.
• The foreign-born laborers: The immigrant workforce living in the company town of Roebling, New Jersey, whose community life, buying habits, and working conditions are organized by the company's management.

In Its Own Voice

"A curious, slow, finical little trade at which the smiths of forgotten races toiled and pottered and ruined their eyesight for unnumbered thousands of years has become, within less than a century, under the spur of modern need and modern driving power, the pack-bearer of the world..."

Context: Introducing how modern industrial wire manufacturing evolved from ancient metalworking.

"Acid in wire steel is like heresy in the church. It has to be purged away."

Context: Explaining the chemical baths and baking processes required after rods are cleaned in acid.

"Each of these cables consists of nineteen strands of about two hundred and seventy-eight No. 8 B. W. G. wires each, and each wire is continuous in its strand, like the yarns in a skein..."

Context: Describing the inner construction of the suspension cables holding up the Brooklyn Bridge.

What It's Really About

The book argues that modern civilization relies on industrial manufacturing processes that remain invisible to the public. Behind high-speed transit, global telecommunications, heavy mining, and long-span architecture lies the technical capability to draw and spin high-tensile steel.

Beyond its technical details, the text serves as a defense of corporate paternalism. It presents a vision where industrial success depends on rigorous material standards, continuous research, and direct management of workers' daily lives. By linking the internal operations of the wire mills to national defense and urban infrastructure, the book argues that corporate organization and engineering precision are the primary forces driving modern progress.

Why Read It Today

This book will appeal to readers interested in early twentieth-century industrial history, mechanical engineering, and American manufacturing culture. It offers a clear look into an era when heavy industry transformed urban life and transatlantic shipping. The prose is clean, direct, and focused on physical processes, providing a vivid sense of the sights, sounds, and heat of early steel mills.

Readers should note the period perspectives present in the final chapters. The text reflects the corporate paternalism of the 1920s, presenting company-owned towns and labor management through an uncritical lens. Its narrative treats corporate intervention in workers' lives as a straightforward benefit. Despite this period bias, the book remains a fascinating primary document that details how wire rope made modern skyscrapers, long bridges, and global communication networks possible.
