SPECIAL ANNOUNCEMEN

which concern specialized in the manufacture of
steel boiler riVets Under Mr.. SternberghS ad-
ministra ton high degree of excellence III this
line was attained and to-day the "Sternbergh
Brand" of this type of rivets is recognized in the
trade advanced standard.
In it's other lines the company has kept pace
with the Development of the Sternbergh rivets,
and its Harvey Grip Thread Track Bolt. tha
only two-pieCe bolt with nut-Ocking feature now
on the market. is in general use
This device is utilized in connection with thu
Ideal Nut. also product of the company. Il
is a carefully made bolt with mathematicaliy
cut ratchet thread that meets a similar thread
on the nut and difference of degrees away
from right angle in each case leaves a cavity
of 10 degrees that is filled perfectly when the
nut is screwed up against the angle bar Tho
nut locks tight by pressure, and according TO
thousands of practical tests will never work
loose.
The screw spike manufactured by this cons
pany is similar to the pattern that has been
used with much success in France and Belgium
for q number of years. The chief advantages
claimed for it that 1t prevents creeping
rails and undulatiOns when used in soft wood
ties: that owing TO the fact that it is placed
in position without the SpIintering force of
hammers it does not cause undue destruction
of the wood fibres. Consequently. the tendency
toward decay is minimzed It holds the rail
SO firmly that it saves much of the wear and
tear found in the ordinary spiked ties and
when heavy loads are borne upon the rails
fastened the effect is to increase the general
stability of the track
Some interesting tests have been made to
show how much stronger is tho hold Of the
screw spike than, the ordinary kind most cx-
wood showed that 1t required over twice the
force to pull a screw spike that it did TO ex-
tract one Of the driven spikes.
Of course, the cOmpany's line of goods is not
limited to the specaties mentioned. but as
each OF the accessories is so important to the
railroad world they have been empha iized in
this article.
The American Iron and Steel Maluf icturing
Company was formed in August, 1888. by a
merger or consolidation. OF j. ri. SteTrbergh Ss
Son. the Pennsylvania Bolt and Nut Company
the National Bolt, Nut and Rivet Works the
Lebanon Iron Company and the East Lebanon
Iron Company.
The capitalization is S.. $50. 900 fully paid In:
the largest bolt and nut makers In the world.
The company operates fifteen rolling mills. and
there are about 1000 employees upon It's pay
rolls The concern Is laying special stress
upon the manufacture Of tho screw spike which
has met with much attention on the part OF
railroad engineers.
AS an incident to the giant business. the fact
may be noted that the manufacture of Cas-
teIlated Nuts. now largely used In the making
of automobiles and locomotives. Is growing
section Of the industry
These nuts have been found particularly eff
fectiYe when used where there Is considerable
vibration and tendency to work loose Recently
experiments have shown the value Of such nuts
in the construction Of car trrciR
While the general offices and part Of the plant
ere at Lebanon. several OF the con1Panys fao-
tories are at Reading. Pena
