(100,000 POUNDS CAPACITY)
To meet the demand for Trucks of heavier capacity, we are building
All-Steel Trucks, which are fully illustrated in the cuts. This design
is the result of a careful study of the prevailing practice in the
large and up-to-date camps of the Northwest, with the aim of combining
simplicity and strength with a minimum dead load. This Truck has been
altered slightly to include all the latest improvements in logging
truck construction, and was awarded the Grand Prize at the A. Y. P.
Exposition.
Wheels, 33-inch Chilled Cast Iron, fitted on M. C. B. Standard
Axles with 9 × 5-inch Journals. Automatic Couplers and
Twin-Spring Draft Gear with M. C. B. Double-Coil Draft Spring.
If desired, Link and Pin Drawbars can be substituted, as our
pattern is interchangeable with Automatic Coupler. Journal Boxes
are M. C. B. Standard. Bolster Steel Channels reinforced with
Steel Cover Plates top and bottom. Draft Sills Steel Channels
with Malleable Iron Draft Lugs riveted to same. Bolster and Draft
Sills are securely tied together and braced with Steel Plates.
Truck Frame of extra heavy Iron Bars, braced at corners with
Gusset Plates, making it impossible for the frame to get out of
square. Bunks, Hercules Patent with Knight Patent Chock. Bunks
are equipped with metal brace as shown in illustration. Castings
are of either Steel or Malleable Iron. Brake Shoes are applied
to all Wheels and Brake Beams, either inside or outside hung, at
purchaser's option. Brake Shaft can be furnished to operate with
lever at end or wheel at side. Weight of 100,000-pound capacity
Truck, 22,000 pounds. Weight of 80,000-pound capacity Truck,
20,000 pounds. Height to center of Coupler, 2 feet, 6 in., or 2
feet, 9 in. Length over Draft Sills, 9 ft. Length over all, 12 ft.

"Snohomish" Logging Truck
[Illustration: Universal Milling Machine]
This illustrates our 80,000-pound capacity Snohomish Truck, with all
Metal Frame and Bolster, but with Fir Draft Timbers. This truck is
designed to couple with standard equipment, with a height of 2 feet, 10
inches to center of coupler and 4 feet, 0 inches to top of bunk. The
Bolster is built up of two heavy Steel Channels reinforced with steel
cover plates top and bottom securely riveted to channels. The Truck is
equipped with Hercules Bunk and Knight Chock and is also fitted with
Metal Bunk Brace.
The same general remarks apply to this truck as to Snohomish Truck No.
123. The frame is of heavy iron bars and the fir draft timbers have a
sectional area of 144 square inches, which offers great resistance to
buffing shocks.
Weight per set trucks, of 20,400 pounds.

"Snohomish" Logging Truck
This truck is especially adapted to use on Logging Railroads, where an
uneven track demands a flexible running gear and an extremely strong
frame. These requirements are carried out in this design by placing
the springs over the Journal Boxes and making the frame of extra heavy
Iron Bars. The simplicity of the design also appeals to the operators,
making it necessary to carry but few extra parts for repairs.
[Illustration: Arch Bar Gang]
Bunk shown is made of straight grain Red Fir, reinforced with
special heavy 12-inch I-Beam closely fitted on timber, but we
recommend our Hercules Patent Bunk equipped with Knight Patent
Chock, McLafferty Stake or Skookum Chock.
Either Automatic Couplers or Link and Pin Drawbars may be used, as
our Link and Pin Drawbar is designed to be interchangeable with
Automatic Coupler, the change being easily made at any time.
Bolsters extra heavy Red Fir, strongly trussed. Draft Timbers,
Red Fir. Draft Gear M. C. B. Standard with M. C. B. double coil
Draft Springs. Truck springs, 70,000 lbs. capacity, heavy double

set.
