chines are driven by individual motors to guard against
shutdowns and are located so that repairs can he made
without interfering with adjacent equipment.
Following the material through the plant in the
order in which it is handled, the raw stock is unloaded
on the west side of the main forge shop building by
means of a 10-ton Milwaukee gantry crane, Fig. 1.
All material received is analyzed and given a systematic
physical examination for pipes, seams, segregation
and other defects. The normal stock of steel varies
from 2,000 to 2,500 tons and is stored according to
size and composition.
May, 1925
Steel requisitioned by the shop is picked up by the
crane, weighed and placed on skids outside the shear
room. The skids are inclined so that the material
moves by gravity into the shear, where it is cut to the
desired length and piled on tote racks. Two shears,
one Pels and one Hilles-Jones, each housed in a separate
lean-to on the side of the forge shop adjacent to
the stock yard, take care of the cutting of material
for all forging machines. Stock is transported to the
machines by means of Elwell-Parker electric trucks.
Forge Shop Ventilation Unique.
The forge shop, Fig. 3 is located in the main building
which is 420 ft. long and 80 ft. wide. It is of modern
brick and steel sash construction affording ample
light. The ventilating system used in this shop is
rather unique but very satisfactory. Instead of entirely
bricking up the space between the ground and
the window sash, swinging doors are provided at intervals
to allow a free circulation of air. The natural
draft caused by the hot gases from the furnaces draws
fresh air in through the swinging doors at the floor
level carrying off with it the heat, smoke and gases
through the V'-shaped monitor roof construction.
The equipment of this department consists of 18
Ajax forging machines, six 3-in., six 5-in. and six 7-in.
The machines are staggered as shown in Fig. 3 so as
to provide ample room for the workmen at the same
time economizing in floor space. All machines are
driven by individual motors ranging in size from 50
to 75 horsepower, manufactured by Allis-Chalmers
Company and General Electric Company. To facilitate
the handling of die blocks individual motor driven

means of electric trucks, the siding tracks being depressed to facilitate loading.
