THOMAS W. SALING, OF MARSHALL, TEXAS.
DRAFT-BEAM FOR CARS.
SPECIFICATION forming part of Letters Patent No. 604,421, dated May 24, 1898.
Application filed November 18, 1897. Serial No, 658,950. (No model)To all wivoim t may concern:
Be it known that I, THOMAS W. SALING, a
citizen of the United States, residing at Mar-
shall, in the county of Harrison and State of
5 Texas, have invented certain new and useful
Improvements in Draft-Beams for Cars; and
I do hereby declare the following to be a full,
clear, and exact description of the invention,
such as will enable others skilled in the art to
13 which it appertains to make and use the same.
My invention relates to improvements in
draft sills or beams for cars; and it consists
in providing such beams with suitable open-
ings or slots whereby the follower-plates may
15 be made to secure the draw-heads of the
coupler to the said cars, the said bars and slots
being of such a construction that the fol-
lower-plates may be inserted after the beams
are secured to the body of the car.
20 It also consists in certain other novel con-
structions, combinations, and arrangements
of parts, as will be hereinafter fully described
and claimed.
In the accompanying drawings, Figure 1
25 represents a plan view of the draft beams or
timbers, the parts being shown in section to
better show the construction thereof. Fig.
2 is a side elevation of one of the said draft
beams or timbers applied to the under beams
30 of a car, and Fig. 3 represents a transverse
vertical section through the said draft-beams.
A A in the drawings represent my improved
draft bars or timbers; B, a follower-plate;
C, a key-plate, and D the draw-head of the
35 coupler.
In applying my draft-beams to the bottoms
of cars they are preferably secured to the
under side of beams running longitudinally
of the car, as E, and are provided with shoul-
40 ders, as a, which are adapted to abut against
a transom or cross-beam, as F, arranged be-
neath the ends of the car. In order to fur-
ther secure the position of the beams A with
respect to the beams E, lugs, as a', may be
45 formed upon the upper surface of the said
draft-beams. These lugs or projections are
adapted to fit in corresponding recesses, as e,
formed on the under sides of the beams E.
The beams A A are designed to be used in
So pairs at each end of the car; but in their
construction each member of the pair is ex
actly like the other, so that they are inter-changeable and can be used upon either side
or either end of the car. The beams A are
preferably formed of channel-irons, as illus- 55
trated in the drawings, and are provided at
intervals with vertical apertures or bolt-holes,
as a2 a2, through which bolts may be passed
to firmly secure the said beams in place be-
neath the car. The rear ends of the draft- 6o
beams are preferably connected by means of
tie-plates, as g g, the upper plate g of which
sets into a recess, as a3, formed in each of the
beams. The lower tie - plate g engages a
shoulder, as a4, formed upon the under side 65
of each of the beams A.
I am aware that metallic draft-beams have
been used heretofore to secure couplers to the
car-bodies; but these have employed lugs or
projections upon their inner surfaces to se- 7o
cure follower-plates in place. This necessi-
tates the making of the beams as rights and
lefts, and they are therefore not interchange-
able.
By my construction of beam all the beams 75
may be made exactly alike and one may be
used in the place of another interchangeably.
As illustrated in the drawings, the draw-
bar D is provided with a reduced end, as d,
and this is adapted to engage and extend 8o
through an aperture, as b, formed in the cen-
tral portion of the follower-plate B. The fol-
lower-plate B is inserted into apertures a5 a5,
formed in the beams A A. A coil-spring is in-
terposed between the follower and the shoul- 85
der d','formed upon the draw-bar D.
In order to secure the draw-bar to the draf t
mechanism, so as to receive the pull exerted
upon the coupler, a key-plate, as C, is passed
through a horizontal slot formed in the draw- 90
head,the ends thereof extending on either side
of the draw-head and through longitudinal
slots, as a5, formed in the beams A A. These
slots a' a' are made sufficiently long to permit
of the movement of the key upon the compres- 95
sion and expansion of the springs. The outer
ends of the key-plate C are engaged by the
loops h of the side draft-rods H H and are there-
by connected with the ends of a similar key at
the opposite ends of the car. It will thus be ioo
apparent that the pull upon the coupler at
one end of the car transmits its pressure to
the spring on the draw-head at the opposite
end of the car, whereas a thrust upon the
