INTRODUCTION

  Craftsmen Machinery Company produced presses very similar to the most popular presses of the small-press era. In fact, they were nearly identical copies. In the case of the 9x12 Monarch, however, they enlarged the common "Pilot" design as conceived by HH Thorpe in 1888 and updated by Chandler and Price during the 20th century.

But this time, I think that they went too far.... After spending a lot of time working with both of these presses, we have concluded that 9x12 is simply too large a surface area to enable application of the pressure required to properly print a full 9x12 form.

The 6 1/2 x 10 Pilot, on the other hand, will print a nice 5x8 form - almost as well as the larger, flywheel-driven 8x12 Chandler & Price "Gordon" style.


Furthermore, Craftsmen seems to have used the original Sigwalt, Caxton, Golding, Victor and other defunct manufacturer's presses as the casting patterns for the presses shown in this 1955 catalog.

 

  • The Superior shown in this catalog appears to be a direct copy of the Early Series Chandler and Price Pilot aka "Thorpe" Pilot designed by Mr.Thorpe of the Cleveland Type Foundry around 1880 or so. Craftsmen later reproduced the New Series C&P Pilot and sold it as their Superior Model as well.

9x12 Craftsment Monarch
(not shown  in 1955 catalog)

9x12 Craftsmen Monarch Platen PressCraftsmen made one of the largest table top platen presses ever built - the 9x12 Monarch.

These two are here for repair and set up for printing. The gray one in the photo here was cast of iron; the orange one was made in Canada and cast of aluminum. The aluminum disk is cast with additional material in a ring around the teeth. The cast iron disk did not need to be reinforced.

                    Monarch Ink Disk Drive AssyBut both suffer from the same - quite serious problem; the ink disk does not always advance and when it does move at all, it's not very much.
 
The cause of this problem is two part. First of all, the disk must be shimmed to the correct height above the disk holder. These presses rquire different thickness shims. The second part of the problem appears to be the length of the cam leg that forces the striker against the disk teeth.9x12 Craftsmen Monarch Ink Disk Drive Assy It simply does not push the striker far enough to rotate the disk and then return to the correct home position. This appears to be a design flaw.

Craftsmen was never known for excellent design. In fact, most (if not all) of their presses were copies of other companies' designs and share little design features in common. This press, for example, appears to be an oversized version of the venerable C&P Pilot, initially designed by H.H. Thorpe in 1888 - and not much modified or improved aside from one design change to "New Style" Pilots by Chandler & Price. Craftsmen's "Superior" press was initally a copy of Thorpe's orginal "Old Style" design, and later was a copy of the New Style design made by Chander & Price.

We propose to install an extension to this cam, which should increase the stroke length of the striker, thereby not only forcing the rotation to increase, but also to enable the return of the striker to a good position beneath the tooth to drive it further as the press is opened.

What's interesting is the Chandler & Price *designed* their striker to wear, and added a replaceable blade to the end of the striker.

What I propose will add a replaceable extension to the cam that drives the striker - sufficient distance to leave a tooth in the right position above it when it returns to home position. This way, it will catch the tooth and drive the disk as the press opens. In both cases, this assures continued successful operation, accounting for wear.

The Craftsmen do not appear to be wear issues, however. I believe that they were simply poorly designed. The parts needed are there, all right, but they don't work well together.

But they will.

And, when they do, we will do some printing on these presses and add to this report.


Update 4/19:

Well, it seems as though I have discovered - and solved (I think) another problem with the manufacture of this 9x12 Monarch.

I was concerned because the ink rollers did not go up as far on the ink disk as I thought they should. When I inked the press, no ink was transferred to the center - it was a blank, round spot. This could not be intentional. In addition, the rollers touched the top of the platen - leaving a line of fresh ink on the top edge of the tympan sheet. This is no way to print!

This is caused by the side linkage that actuates the roller carriage. It was too short! In fact, when I compared it to the linkage on my 6 1/2 x 10 C&P Pilot, it was the same! How could this be? The 9x12 is much larger than the C&P Pilot.

And then, I got to thinking... Craftsmen cloned other manufacturer's presses. They did not design new presses of their own. They copied other presss - and copied others' mistakes. But in this case, I knew that Craftsmen also copied the Thorpe/C&P Pilot.

So, I got to thinking... "what if..." and it turns out that the linkage used on these two 9x12 Monarch presses was actually a Pilot link!!!

I made a new one - 1/4" longer than the original - with the mounting holes 1/4" further apart.

Now the rollers roll as I would expect and the ink disk no longer has a bald spot in the center.

I think that what happened was either that the assemblers grabbed the wrong part (there is only 1/4" difference in the placement of the mounting holes) or they ALL used the wrong part... Curious...

We'll do some printing on this press tomorrow and add another update with the results....


Chase size and Lever actuated vs Flywheel-driven presses
Another point worth making regarding the size of this press' chase:. The chase of the Monarch is almost as large as the 9x13 chase of the Kelsey Excelsior 9x13 and larger than the chase of the popular 8x12 Chandler & Price press.

However, the C&P is a flywheel-driven press whereas this one is a lever-operated press. They operate at different speeds and the flywheel of the C&P enables momentum stored in the mass of the flywheel to accomplish a stronger, momentary dwell of the platen (& paper) against the form. To match this amount of pressure, quite a bit of force would have to be applied to the lever of the Monarch. This could stress the castings - either cast iron or aluminum, and cause damage to the press. Historically, a pipe would often be added to the side arm lever of the C&P Pilot press, resulting in many Pilot handles and rocker shafts being broken due to stress. I have repaired Pilot presses damaged in this way. This press carries that same potential - IF the printer tries to apply more pressure - to get more "punch" in the impression...
