While the employer is under a duty to exercise ordinary care to
supply machinery and appliances reasonably safe and suitable for
the use of the employee, he is not required to furnish the latest,
best, and safest, or to discard standard appliances upon the
discovery of later improvements, provided those in use are
reasonably safe and suitable.
Subject to this rule, the question whether the appliance which
caused the injury in this case, and which was not of the latest
type, was reasonably safe and suitable was properly submitted to
the jury.
Assumption by a locomotive engineer of the ordinary risk of
using a lubricator glass when subjected to a normal bursting strain
does not import assumption of an increased and latent danger
attributable to the employer's negligence in maintaining the
appliance upon an engine carrying an undue pressure.

The facts, which involve the validity of a judgment for damages
for personal injuries in an action under the Employers' Liability
Act, are stated in the opinion.
MR. JUSTICE PITNEY delivered the opinion of the Court.
We have here under review a judgment of the Supreme Court of
Nebraska affirming a judgment in favor of defendant
Page 241 U. S. 471
in error in an action based upon the Federal Employers'
Liability Act of April 22, 1908 (c. 149, 35 Stat. 65), for the loss
of an eye caused by the breaking of a lubricator glass on a
locomotive engine upon which he was at work as engineer in the
employ of plaintiff in error. 96 Neb. 419.
No question is made but that the cause of action arose in
interstate commerce so as to bring the case within the federal act.
The facts upon which the question of liability depends are these:
the plaintiff in the action (defendant in error) was an experienced
locomotive engineer. At the time of his injury, which occurred at
night in the month of November, 1910, he had just oiled his engine,
taken it from the roundhouse, and placed it upon the outgoing track
in readiness for his run. The engine was equipped with a Nathan
lubricator, an appliance containing oil for the steam cylinders and
the air pump, the oil being conducted to and within the parts where
needed under steam pressure from the boiler. In order to give the
engineer a view of the interior of the apparatus, and thus enable
him to see that the oil was dropping, three cylindrical glass tubes
were attached, one carrying the oil for each steam cylinder and one
for the air pump. Each of these glasses was surrounded with a
shield of perforated metal in two parts, hinged together and
lightly clamped upon the glass tube by means of a spring to hold it
in place. When the lubricator was in operation, the tubes were
required to sustain the same steam pressure as the boiler. These
tubular glasses would sometimes break. This was most liable to
occur (1) when a glass was newly installed, and before it had been
properly tempered; (2) when it was subjected to a sudden change of
temperature, as when steam was admitted to it while cold, and (3)
they would, after six or seven weeks' use, sometimes "wear thin"
and break for this reason. The metal shield was designed in part at
least, to prevent injury to the
Page 241 U. S. 472
engineer from flying pieces in case the glass should break. This
type of lubricator had been in use for over twenty years, and had
been used upon all defendant's engines down to a time between three
and four years prior to the accident. Then a new type, known as the
Bull's Eye, came into use, and was recognized as a better appliance
because, being unbreakable, it was safer for the engineer, and at
the same time obviated the loss of time and delay of trains
attributable to breakage of lubricators of the Nathan type, and
defendant began to install Bull's Eye lubricators in the place of
the older type upon engines already in use, and to place them upon
all new engines. During the earlier period of the use of the
Nathan, and before the construction of locomotives of classes Q and
R, the engines carried only 140 to 150 pounds boiler pressure,
while engines of the classes mentioned carried 190 pounds. An
experienced witness called by defendant testified that, at the time
of the trial (about a year after the accident), approximately 25
percent of the engines were still using the Nathan lubricator and
75 percent were equipped with the Bull's Eye; that the Bull's Eye
was and had been, for three or four years, recognized as "the
proper appliance;" that the Nathan was dangerous to the men, and
that the change was being made partly because of this and partly
because the breaking of the old style lubricator sometimes delayed
trains.
Plaintiff testified that, during most of the time for the past
twenty years, he had operated locomotives equipped with Nathan
lubricators having tubular glasses, but not all of these were
high-pressure engines. The engine on which he was injured was of
class R, and carried a boiler pressure of 190 pounds. He had
operated it for about two months prior to the time of his injury.
During his experience of twenty years, lubricator glasses had
broken with him on three previous occasions, the last being about
three weeks before the occurrence in question. At this
Page 241 U. S. 473
time, he asked that a Bull's Eye be substituted on his engine.
He testified that this was not because he considered the old
lubricator dangerous, but because he wanted to save time on the
road in the event of a breakdown. He also testified that he knew
that, when a new glass was put into a Nathan lubricator, it was
liable to burst if the steam was turned on suddenly or if steam was
turned on quickly in cold weather, and that, on the occasion in
question, following the correct practice, he first partially opened
the throttles, admitting the steam to the tubes to warm them,
afterwards fully opening the throttles, and that it was about seven
minutes after this was done that the explosion occurred.
The trial court submitted the case to the jury with instructions
to the effect that the burden of proof was upon plaintiff to show
that defendant had carelessly and negligently maintained the shield
and spring and glass in the lubricator in a weak and dangerous
condition, that the lubricator glass was not of sufficient strength
for use upon the engine in question or any other engine carrying
190 pounds of steam, and that this fact was known to defendant, or
that its experience with said glass and lubricator had been such
that it ought to have known that the same was insufficient and
dangerous, and that, if they believed from a preponderance of the
evidence that defendant was thus negligent, and that plaintiff was
injured as a result of it, they should find for the plaintiff,
otherwise for the defendant.
The principal controversy is as to whether the evidence was
sufficient to go to the jury upon the question of defendant's
negligence in furnishing the locomotive in question with a
lubricator having tubular glasses as described.
The rule of law is that the employer is under a duty to exercise
ordinary care to supply machinery and appliances reasonably safe
and suitable for the use of the employee,
Page 241 U. S. 474
but is not required to furnish the latest, best, and safest
appliances, or to discard standard appliances upon the discovery of
later improvements, provided those in use are reasonably safe and
suitable.

135 U. S. 570;
Patton v. Tex. Pac. Ry. Co., 179 U.
S. 658,
179 U. S. 664.
In our opinion, a correct application of this rule required the
present case to be submitted to the jury. Properly limiting the
inquiry (and, as we have seen, the trial court did so limit it),
there was no question of attributing negligence to an employer for
merely failing to promptly install the latest, best, and safest
appliance; it was a question of keeping an older type of appliance
in use after its insufficiency had been demonstrated by experience,
and perhaps under conditions materially different from those which
had obtained when its use began, in the face of notice that it was
not reasonably safe and suitable. It was reasonably inferable from
the evidence that defendant's experience had shown that a glass
tube capable of withstanding the lower pressures of 140 to 150
pounds could not be relied upon to withstand a pressure of 190
pounds, and that the difficulty could not be obviated, as was
attempted, by using thicker glass for the tubes, because its very
thickness increased the danger of bursting when steam was first
admitted, there being evidence from a witness called by defendant
that the older type of lubricater was a dangerous instrument to be
used upon a high-pressure boiler, and that they broke rather
frequently; that it was for this reason, in part, that defendant
had introduced the Bull's Eye, beginning three or four years before
the accident, installing them first upon high-pressure engines of
the Q and R classes, and having already placed them upon a majority
of defendant's engines of all sizes. In this state of the evidence,
it could not be said as matter of law that defendant was free from
negligence in delaying so long to install a Bull's Eye lubricator
upon the engine in question.
Page 241 U. S. 475
The only other question relates to whether plaintiff assumed the
risk of performing his duty upon a locomotive equipped with the
Nathan lubricator. Instructions were given to the jury upon the
subject, but they are open to some criticism which perhaps can be
obviated only by holding, as the Supreme Court of Nebraska held,
that there was nothing in the evidence that would sustain a finding
that plaintiff assumed the risk.
The crucial question is whether he knew or had sufficient notice
of the increased danger attributable to the employer's negligence.
Plaintiff testified without contradiction that it was his
understanding -- he had been "always taught to believe" -- that the
Nathan lubricator would stand the boiler pressure of 190 pounds.
Assuming, as the undisputed evidence shows he had a right to
assume, that the glass was being subjected to no greater bursting
strain than it was designed to withstand, he still knew that, under
special circumstances that have been pointed out, there was danger
of a glass bursting unless precautions were taken. Any risk of this
character, unaffected by his employer's negligence, he undoubtedly
assumed as a risk ordinarily incident to the occupation he pursued.
But this throws no light upon his right to recover, because if he
was subjected to no greater risk than that just now indicated, the
employer was not negligent, and there was no ground of recovery.
Under the trial court's instructions, the jury must be presumed to
have found that the Nathan lubricator glasses had been shown by
experience to be incapable of withstanding a pressure of 190
pounds, that defendant knew of this, and nevertheless negligently
maintained such glasses upon plaintiff's engine. There was present,
therefore, an extraordinary danger not normally incident to
plaintiff's employment; it was in its nature latent, and not
obvious, and there is no evidence in the record that plaintiff had
received any notice or warning of the increased hazard attributable
to his employer's
Page 241 U. S. 476
negligence. In short, while he knew there were certain dangers
naturally incident to the use of tubular glasses upon the
lubricator, there is nothing to show that he knew or had any ground
to believe that his employer had been wanting in the exercise of
proper care for his safety, or that, because of such want of care,
the danger to him was greater than it ought to have been. Without
this, he could not be held to have assumed the increased risk.
