a
the same time securely lock the transoms to
the side frames, and if any of the parts be-
come broken, the bolts may be readily re-
thoved and a new part or parts substituted.
Each of the transoms is provided with a
vve'tically disposed web 33 and upper: and
lower webs or ribs 34-35, respectively, and
the upper ribs are provided with projecting
lugs 36 and 37, so that, if necessary, the
to ordinary brake mechanism may be attached
to the truck. The lu gs 36 serve for connec-
tion with the brake )ever stops of outside
brakes, while the lugs 37 may be cmuployed
for attaching the. several hangers of inside
J5 brakes of the beam type.
Near each end of each of the transoms is
arranged a pair of spaced lugs 40, each pair
of lugs being provided with upper and lower
openings 41 and 42, the upper openings serv-.
zo ing when necessary for the attachment of the
inside hung brake beams of the ordinary typ.
The lower openings serve for the passage of
pivot.pins 44 which carry.the. levers 45 of a
seamless brake which forms one of the lea-
25 tures of the invention. Each of the levers
45 carries at its lower end a brake shoe head
46 to which may be attached a. brake shoe
47 of .any ordinary cons truction.
r"In artanging the braking system, provision
30 is made for exercising a direct pul. on all of
the brake lever connecting rods, so that
there shall be no thrust strain. For this pur-
pose the primary lever 50 is pivoted at 51 to
a part of the car frame and the secondary
35 lever 52 is pivoted at 53 to the car frame.
The piston rod 54 of the brake cylinder exer-
cises a direct outward thrust on the lever 50
and this pulls the connecting rod 55 in the
direction indicated by the arrow in Fig. 7..
40 This movement is transmitted to a cross bar
58 by a connecting rod 59, and from the
cross bar is.transmitted through a pair of
rods 60 to the lever 61 which flatter is con-
nected to the two brake shoe carrying levers
45 by connections 62. The same construction
is followed at the opposite end of the car.
A truck constructed in accordance with.
this invention has but few parts, and -these
may be readily made at small cost, and in
5o case of accident a broken part may be readily
replaced. The truck is further so con-
structed as to permit of the. application
thereto of the beamless brake described, or
the old style inside or outsin brakes if pre-.
55 feared, without change in the structure.
I claim:-
1. In a car truck, a pair of side frames hav-
ing centrally arranged recesses, a truck bol-
ster having its ends extending into said re-
4 cesses, transoms extending between the sideframes, the transoms and side frames being
provided with interfitting lugs, and bolts ex-
tending through said frames.
2. In a truck, a pair of side frames having
centrally'arranged recesses and provided on 65
their inner faces with lug receiving pockets, a
pair of transoms extending between the side
frames and having lugs exteiiding into said
pockets, a bolster disposed between the tran-
soms and having its end portions fitting 70
within the recesses, tie plates for limiting up-
ward movement of the bolsters, and bolts ex-
tenling through the tie plates and lugs and
serving to secure the transoms to the side
frames. 75
3. The combination in a truck, of side
frames having centrally arranged recesses
provided with spring receiving pockets, the
inner faces of the frames having spaced lug
receiving p ocki.ets, a pair of transoms having 8o
end lugs fitting within the pockets, a truck
bolster fitting within the transoms and hav-
ing its ends arranged within the recesses, the
lower face of the bolster having spring pock-
ets, ,springs for supporting the bolster, tie 85
plates extending over the tops of the recesses
end. limiting upward movement of the bol-
ster, the opposite ends of the tie plates being
provided with downwardly extending lugs
hitting ii corresponding recesses in the side 90
frames, and securing bolts extend ing through
the tie plates and the transom lugs.
4. A built up truck comprising side
frames, a pair of .transoms extending be-
tween the side frames, a single vertical bolt 95
forming the connection between each end of
each transom and the side frames, and a
truck bolster arranged et ween the transoms,
said bolster having laterally projecting logs
at or near its outer 0nds. 100
5. IA built up truck comprising a pair of
side farimes having central recesses all pro-
vided with arms projecting from both ends
for the reception of journal boxes, a pair of
transoms extending between the sidle frames 105
and bolted thereto, a truck bolster having its
ends arranged within the recesses and pro-
vided with lugs that hear against the outer
faces of the side frames, tie plates crossing.
the recesses and limiting upward movement to
of the bolster; and supporting springs for said
bolster.
In testimony that I claini the foregoing as
my own, I have hereto aflixe(l my signature.
In the presence of two witnesses.
