National Museum’s John Bull

[Illustration: Figure 29.—Pre-1900 photo of _John Bull_, oldest

complete and operable locomotive in North America, now in National

Museum.]

Probably the most famous and historic old locomotive in the United

States today is the _John Bull_, the oldest complete and operable

locomotive in the country (figure 29). Built in England in 1831 by

Robert Stephenson & Co. of Newcastle-upon-Tyne, it was officially placed

in service on November 12, 1831, at Bordentown, N. J., on the lines of

the Camden and Amboy Rail Road and Transportation Co., now a part of the

Pennsylvania Railroad Co. In regular service until 1865, the locomotive

was given by the Pennsylvania Railroad Co. to the National Museum in

1885 (USNM 180001). It should not be confused with another

Stephenson-built locomotive of the same name, built for the Mohawk and

Hudson Rail Road Co. at the same time but no longer in existence.

The Camden and Amboy’s _John Bull_, its first locomotive, was ordered

from Stephenson by Robert L. Stevens of New Jersey, son of the railroad

pioneer Col. John Stevens, and president of the company, who had gone to

England in October 1830 for this purpose, as well as to purchase iron

rails of his design for the track of the new railroad.

The locomotive was completed early in the summer of 1831 and was shipped

from Liverpool on the ship _Allegheny_, which sailed for Philadelphia on

July 14. It had been disassembled for shipping, as were most of the

early locomotives, and it is interesting to note that the freight charge

was only £19, or a little under $100. The total cost of the locomotive,

incidentally, was £784 7s. 0d., or a little under $4,000.

The engine arrived at Philadelphia about the middle of August, and was

then transshipped by sloop to Bordentown, near Trenton, whence a few

miles of rail were soon to head northeastward toward South Amboy. The

mechanics who assembled the locomotive found it a mysterious and

completely unfamiliar device. After considerable experimentation the

task was successfully accomplished under the leadership of Isaac Dripps,

a local youth who later rose to a position of importance in the

Pennsylvania Railroad.

In its first test the locomotive was fired up to 30 pounds steam

pressure, and Dripps, with Stevens by his side, opened the throttle of

the first locomotive of what was to become part of the Pennsylvania

Railroad Co. The engine was disassembled for a few minor modifications

shortly after this trial, and a few weeks later, on November 12, the

official first trip was made.

The _John Bull_ as it appeared when first placed in service in 1831 was

described in detail by J. Elfreth Watkins in his “Camden and Amboy

Railroad,” published in 1891. He wrote:

The engine originally weighed about ten tons. The boiler was thirteen

feet long and three feet six inches in diameter. The cylinders were

nine inches by twenty inches. There were four driving wheels four feet

six inches in diameter, arranged with outside cranks for connecting

parallel rods, but owing to the sharp curves on the road these rods

were never used. The driving wheels were made with cast-iron hubs and

wooden (locust) spokes and felloes. The tires were of wrought iron,

three-quarters of an inch thick, the tread being five inches and the

depth of flange one and a-half inches. The gauge was originally five

feet from center to center of rails. The boiler was composed of

sixty-two flues seven feet six inches long, two inches in diameter;

the furnace was three feet seven inches long and three feet two inches

high, for burning wood. The steam ports were one and one-eighth inches

by six and a-half inches; the exhaust ports one and one-eighth by six

and a-half inches; grate surface, ten feet eight inches; fire-box

surface, thirty-six feet; flue surface, two hundred and thirteen feet;

weight, without fuel or water, twenty-two thousand four hundred and

twenty-five pounds.

After the valves were in gear and the engine in motion, two levers on

the engineman’s side moved back and forth continuously. When it was

necessary to put the locomotive on the turn-table, enginemen who were

skilled in the handling of the engines first put the valves out of

gear by turning the handle down, and then worked the levers by hand,

thus moving the valves to the proper position and stopping the engine

at the exact point desired.

The reversing gear was a very complicated affair. The two eccentrics

were secured to a sleeve or barrel, which fitted loosely on the

crank-shaft, between the two cranks, so as to turn freely. A treadle

was used to change the position of this loose eccentric sleeve on the

shaft of the driving wheel (moving it to the right or left) when it

was necessary to reverse. Two carriers were secured firmly to the body

of this shaft (one on each side of the eccentrics); one carrier worked

the engine ahead, the other back. The small handle on the right side

of the boiler was used to lift the eccentric-rod (which passed forward

to the rock shaft on the forward part of the engine) off the pin, and

thus put the valves out of gear before it was possible to shift the

sleeve and reverse the engine.

As no tender came with the locomotive, one was improvised from a

four-wheel flat car that had been used on construction work, which was

soon equipped to carry water and wood. The water tank consisted of a

large whiskey cask which was procured from a Bordentown storekeeper,

and this was securely fastened on the center of this four-wheeled car.

A hole was bored up through the car into the barrel and into it a

piece of two-inch tin pipe was fastened, projecting below the platform

of the car. It now became necessary to devise some plan to get the

water from the tank to the pump and into the boiler around the turns

under the cars, and as a series of rigid sections of pipe was not

practicable, young Dripps procured four sections of hose two feet

long, which he had made out of shoe leather by a Bordentown shoemaker.

These were attached to the pipes and securely fastened by bands of

waxed thread. The hogshead was filled with water, a supply of wood for

fuel was obtained, and the engine and tender were ready for work.

The distance between the two main axles on the locomotive is just 5

feet, and the gauge is 56½ inches. The overall length of the locomotive,

including the pilot, is 25 feet; of the tender, 12 feet.

Watkins has given the cylinder bore as 9 inches, a figure also used by

C. F. Dendy Marshall in his “Two Essays in Early Locomotive History,”

and by J. G. H. Warren in his “A Century of Locomotive Building,” both

excellent publications. In fact, however, the cylinder bore of the _John

Bull_ was recently measured and found to be 11 inches. The stroke of 20

inches as cited by all is correct.

[Illustration: Figure 30.—Another pre-1900 view of _John Bull_,

which was built in England by Stephenson in 1831.]

Many changes, some minor and some major, were incorporated in the _John

Bull_ during the next few years. The most noticeable was the addition of

a 2-wheeled pilot, suggested in 1832 by Robert L. Stevens to guide the

locomotive around the sharp curves common in the tracks of that era. In

order to attach the pilot to the front axle, the outside rods and cranks

connecting the front and back axles had to be permanently removed, thus

reducing the number of drivers from four to two. The _John Bull_ has

ever since been driven by only the two rear wheels (figure 30). The

wheels of the pilot are 29 inches in diameter.

Another early permanent change was the replacement of the wooden-spoked

wheels with those of cast iron. The old wooden carriage-type wheels

could not stand up under service in America, where sharp curves in the

tracks prevailed. A wheel, said to be one of the originals (figure 31)

but lacking the flanged metal tire, was presented to the National Museum

(USNM 181194) by the Pennsylvania Railroad Co. in 1894. An inch or so

less in diameter than 54 inches, the wheel would certainly be of the

original size if the tire were in place. The 14 spokes and the felloe

are of wood. Metal bands, similar to the crank rings of the _America_

(now affixed to the reconstructed wheels of the restored _Stourbridge

Lion_, see p. 20), are included in the construction of this old wheel of

the _John Bull_.

[Illustration: Figure 31.—Original wooden-spoked wheel of _John

Bull_, in National Museum.]

Whether or not it is one of the original wheels applied to the

locomotive by Stephenson can not at this time be definitely proved.

Possibly it is an early wooden-spoked wheel built and tried by the

Camden and Amboy prior to the adoption of the all-metal wheels now on

the locomotive. Another similar wheel, until recently located in the

Pennsylvania’s library in its Suburban Station Building in Philadelphia,

is now in storage. These two wheels were included in that railroad’s

exhibit at the World’s Columbian Exposition in 1893.

Among the many other changes to the _John Bull_ were the addition of a

bell, a whistle, and a headlight, as well as a dial-type steam pressure

gauge (figure 32), and the relocation of the axle springs, the water

cocks, the safety valve, and the steam dome. At one time a cab was

installed at the rear of the locomotive, and an 8-wheeled tender was in

use (figure 33).

The tender as seen today is basically original, but much of the woodwork

was in such poor repair that it was completely disassembled in 1910 and

stored, the rotted pieces of wood being discarded. In 1930 the tender

was completely restored at the Altoona shops of the Pennsylvania

Railroad Co., and since that time has been exhibited constantly with the

locomotive.

Prior to its presentation to the National Museum, the _John Bull_ had

appeared at the Centennial Exhibition at Philadelphia in 1876, and at

the Exposition of Railway Appliances at Chicago in 1883. In early 1893,

the locomotive and tender were taken from Washington to New York City,

and on April 17 proceeded under steam, pulling two old cars of the

period of 1836 (figure 34), to the World’s Columbian Exposition at

Chicago. It arrived without mishap on April 22 after having covered 912

miles. The locomotive and tender were returned to the Museum in December

1893 after having made daily demonstration runs at the exposition. They

returned to Washington under steam via Pittsburgh, Altoona, Harrisburg,

and Baltimore. The next time the locomotive left the Museum’s confines

was for a brief sojourn at the Fair of the Iron Horse in 1927 (figure

35). More recently it appeared at the Chicago World’s Fair in 1933 and

the New York World’s Fair in 1939 and 1940.

In early 1940, a full sized operable replica of the _John Bull_

locomotive (figure 36) was made at the Altoona shops of the Pennsylvania

Railroad Co. The cylinder dimensions of 11 by 20 inches were apparently

known by the shops at that time, as the drawings made then for use in

building the replica show the bore and stroke to be 10⅞ by 20 inches.

Perhaps the bore of the original locomotive was also 10⅞ inches in 1831,

and was increased to 11 inches through many years of wear. However, the

figure of 9 inches for the bore, so often used in the past, is

definitely incorrect.

[Illustration: Figure 33.—As this early photo shows, the _John Bull_

toward the end of its active career had a cab and large smokestack,

and an 8-wheeled tender was used.]

Earlier, in 1927, a full sized replica of the tender had been

constructed at Altoona. This replica of the tender appeared with the

original locomotive at the Fair of the Iron Horse in 1927, but since

1930 the restored original tender has always appeared with the original

locomotive. In 1940, the replica of the locomotive, accompanied by the

replica of the tender, appeared at the New York World’s Fair as a moving

exhibit, while the original locomotive and tender appeared there as a

stationary exhibit. The replica again appeared at the Chicago Railroad

Fair in both 1948 and 1949. When not on exhibition, the replica is

usually stored at the Pennsylvania’s enginehouse at Northumberland, Pa.

A small, nonoperable model of the _John Bull_ and its tender (figure

37), with two of the cars of the 1831 period, together about 6½ feet

long, was made in the National Museum by C. R. Luscombe about 1900, and

is included in the Museum’s collection (USNM 233510). The units are

represented as the originals appeared in 1831, without the pilot on the

locomotive, and without the sides and top on the tender.
