Standard No. 6 Press
Standard No. 4 Press
General Description
Marshalltown presses are designed to provide speed, strength, safety, durability, and
economical operation and maintenance. All assembly parts are accurately machined
and fitted by means of jigs and fixtures, assuring proper performance and making parts
interchangeable. Only the highest grade and most carefully, selected materials are used.
Increased depth of die space is provided by the design, allowing for the use of
leader pin dies.
Rugged Semi-Steel Frame
The frame is a one piece semi-steel casting so designed and proportioned as to give
maximum rigidity and special reinforcement in the bearings and the throat. Tie rod
lugs are cast on the frames of the No. 3, No. 4, No. 5, and No. 6 presses. The main
shaft bearings are large in length and diameter. Inclining attachments are furnished
on all sizes at no extra charge.
Chrome
The crankshaft is a solid chrome nickel steel forging, and the clutch housing is
forged integral with the shaft. The shaft, large in both bearing and crank, extends out
on the left side, so that a collar tor automatic feed can be attached. Main bearings have
felt oilers in the cap. The brake band is in two halves, hinged at the back and held to
gether with a bolt and a lock nut. A spring maintains constant pressure.

The slide is fitted with a crossbar
knockout, the knockout brackets
being fastened to the frame and not to

Tool Steel Square Pin Clutch
The clutch is of the square pin pat
tern and is very large—giving wide
striking surface. The latch has a
toggle connection to the treadle pro
viding utmost safety. There
are three
points of engagement in the flywheel,
giving almost instantaneous action.
A safety pin is provided to lock the
clutch out of engagement, so that dies
may be set with safety while flywheel
is in motion.

main bearings, bar knockout in slide, square hole for
punch shanks and safety lock for clutch pin.
Modifications
When so specified and at an extra charge
the following can be supplied
Change of stroke
Increase in die space (No. 5 size only)
Intermittent brake
Flanged slide for large dies
Motor
drive (see page No. 4)
Back gearing (see page No. 5.)

Bronze Bushed Flywheel
The weight of the wheel is correctly pro
portioned for the rated capacity of the press.
The illustration shows the bronze bushing and
the renewable steel striking and locking pins.
The locking pins take up rebound as shaft
passes over center when using spring, rubber
or air cushions.
Wrist Pin Connection
This feature is more expensive to manufac
ture than the ordinary ball and socket connec-
tion but is vastly superior. Years of
—
HH operation show practically no wear.
The wrist is carefully fitted to a hand-
scraped perfect seat in the slide,
jk
Pressure of operation is distributed
U c 1 over a wide area as compared to the
i relatively small area of the ball and
i socket type. No special wrench is
I /
required for adjustment.

No. 0 Bench Press
Q
The Mighty Midget illustrated at the left has
been developed in response to the demand lor a
better than ordinary bench press. Heavier con
struction, greater die space, improved ball and
socket connection and easier adjustment are fea
tures of the design.
'1'he press is equipped with an improved con
vertible clutch, which permits either single stroke
continuous operation. The conversion is simply
or
and easily made. This press can be furnished for
either individual motor drive or lineshaft opera
tion. If the former, either V Belt or flat belt drive
is available.

illustration. See specification page for additional
information.
Individual Motor Drive
When so specified and at an extra charge all
flywheel or geared presses, except the convertible
type, can be arranged for individual motor drive.
The individual belted motor drive on flywheel
presses includes the bracket and the idler pulley.
V Belt motor drive, includes bracket, belt and
sheave.
We can also furnish and mount motors and
starters al current list prices,
desired information pertaining to the voltage,
kind of current, number of cycles, etc., should
be given.
Ball bearing motors are recommended because
lubrication is a consideration when presses are
operated in the inclined position.
The approximate horsepower and speed of the
motors required for each press is shown on the
specification page.
