small par,, 81 gentlemen including The principal OF
soers Of The Harlem Railroad Company, took IMP
rs far a. Whams's Bridge on Thursday 10 test ahe"
s,rm Of car spiing recently spilled 10 one car now
rrru;n, on that road. Mr.. McCalum and other OH
,,.-s az the Now.York and Erie Road also took
shor. trip for the same purpose in car similarly pro-
xdad ON that extensive line Of travel the result beng
in both cases highly iattering 10 the inventor we
learn that a car similarly fitted and owned by The In
veu,or or by q company formed TO carry out his IN
ep,ions has been some six months in use on the Bal
tmore and Ohio and other roads in that nelghoor-
hood and has been thus far attended with the most
marked success One Of the most attractive quahtiee
beopgipg 10 this Invention is lis cheapness set Tor
car complete costing only about $40 or si5, while the
steel springs frequently employed cost abou twice as
much and the now popular rubber springs cost from
the like amount TO $3.50. The elastic material en-
Moved is common atmospheric air, and the peculiar
,y of the invention consists entirely in the method OF
combining it. The old air-spriDgs employed to con-
siderable extent on some Ioads few years since con-
sisted of a vertical cylinder, opened at the bottom
and furnished with piston thrust up from below 1t
was abandoned in consequence of its unavoidable
leakage The present spring consists of similar cyl
inder or rather a rough cup in an inverefposition
provided with flexible but air-tigbt partition or da-
pbrscm across its under side, and against the under
surface of this suitably rounded mass of wood is
allowed to press The sir is compressed in the cup
by The aid of small band-pump, and the rresulari-
ties of the track cause the diaphragm to be bent al
ternately inward and outward, so that the whole
yeclt is supported on the cushion Of air yet with
out allowing the least possible chance for the escape
Of the fluid. The diaphragm is composed of several
thicknessee Of india rubber stout and leather,
and as still further protection is covered on the in
side with str alum Of good sugarhOase modsseS, SO
that the air in fact acts against fluid piston The
cast iron cup is lined on its top and sides with tin to
prevent the possible escape of cir through its pores,
and the air, although compressed to density Of some
40 h per square inch, s found in practice to be
completely and perfectly retained while the motion of
the car s as may be supposed of the gentest pos
sble character There is no friction, and the only
part of this spring which can fail is the diaphragm,
which can be easily and cheapy replaced when nee
essaTy.
BAILEY ADJUSTABLE CAR SEAr.--Six splendid pas
senger cars, now in process of construction at Pier
mont for use on the New-York and Erie Railroad,
to be provided with form of seat adjustable at pleas
ure 90 as to be equally well adapted for an upight
seat or an almost reclining lounge. The material of
the frame is cast ron and the seats-which coseyre-
semble, when in upright position, the car seats
now in general use-cost less in fact than those any
oyed N
backs are connected to eacu other and to the fixed
frame by rods or links which allow corresponding
motion to each, and the parts are so balanced by
very simple and substantial arrangement that the pas
sengers. by simply throwing their bodies backward or
forward with moderate degree Of force, may change
the position of the back to any angle required. The
seat proper s always horizontal, the back alone being
change alb in its degree Of inclination. 1t difficult
to convey, without the aid of engravngs, very dis
tnct idea of this great Improvement To attempt it,
however we should divide the whole into four rath
or Fix distinct parts First: The fixed frames one at
each end of the seat and rising to point about mid
way between the seat proper and the arres!s. Sec
ono: The arm rests two in number, entirely distinct
from and independent Of the frames Third: The
seat: and Fourth: The back. The sea- back aud arm
rests are leitler of them fixed firmly The seat is sus
repoed to toe frame by two vertical links al each side
which iuks ere continued upward and support the
ann rests at their upper extremties the whole being
loosely Joint. together at each connection by suti
BE riy,t Two additional links at each end OF the
seat onted one to the seat proper and the other TO the
arm-rest extend horizontally backward and take hold
of the back. With this arrangement, by the aid OF
the flexible joints the relative position of all the parts
NAV be easily adjusted. A " friction piece IL pro-
vded at the walside, which presses with considera'
bic force against the end of the seat and assists 1t in
retaining any position given it, however loose the rv
eted joints may become by reason of loug-contiuued
wear OF bad workmanship. But for this " friction
piece il will be readily there is no wear of any
parts except in the rvet holes; and the frames, links,
arurrests &C., may be made as ornamental as desired
or may be bronzed or glded at pleasure. This seat
appears Ell rather brief examination, TO be entirely
free from any of the faults apportanDg - the previ'
GUS forms of adjustable seats. 1t is readily rover sed
by simply lifting over the back which upholstered on
each face and the isbl ty to arrangement or fracture
seems TO be reduced to the lowest practicable smoun
Provision is made for preventing the possibility OF in
Jury to the hands of iEfanis Others in suddenly
changing the position Of the seat and one of great
est recommendations is the fact that no catches or
other deraDgeable pepe1ing fsstenags ere required
SLEEPING IN RAILROAD CARs.-Mr. S. Cuiver Of
Newark, Wayne County, n. Y, has invented very
simple and comfortable apparatus by which travel
er can sleep in a railroad without any OF the in
convenience usually attending that recreation. The
apparatus consists of bit OF seting fastened by
hook TO the roof of the car With net at the end in
which the head can be laid at sny elevation or single
desired. 1t is most ingenious contrvance, aud SO
light TO be easily carried in ores pocket All rail-
roads running night trains should make arrangements
