Arab press installed on a slope?

This chase is currently up for auction. Presumably used by a letterpress printer with their press on a slope.

I would expect this chase to permit smoother inking on forms locked up with the lines of type running across the chase. In such a lockup the rollers tend to bounce from line to line and the angle would reduce that, making the inking cleaner. IMHO

I am eager to know the patent number on the chase and have written the seller to ask. I hope they will reply. It would be interesting to hear the maker’s description of this one!

I have seen similar chases from the late 19th century before. They were designed this way to replace one half of the quoin with the chase wall, meaning you could lock up with half the number of wedges. Steve Saxe has a scan of an ad for one of these on his Flickr page. I’m on my phone right now, or I’d paste a link.

That style chase was often employed to accommodate ruled forms thus extending the life of composition and softer rubber inking rollers; far safer than using angle furniture.

I saw a set of Hamilton furniture that were wedges of a similar angle. I imagine these were for the same purpose?

Chases of that style were first made to help register on Klymax or Peerless presses, 8x12 C&P presses that were fitted up with a Kelly B feeder. Great little presses with horrible register, the angle (bias) chase helped the special side guide (which is a whole nother story) meet and get the sheet somewhere in register. I believe the 1923 ATF book (not in the 1912) shows the press, the chase and the side guide. The angle chase I have shows only manufacturers logo, under a few layers of ink, along with a serial number. It helps feeding and it certainly helps to ink up a heavier form.

I’m currently printing a design with a border. Since the section of the border that is perpendicular to the rollers takes its ink from the same narrow place on the rollers for its whole length, I was wondering to myself whether anyone ever locked up a form having a border at an angle, to avoid this problem.

I suppose with a chase like this, it would be possible! But we’d need special quoins or furniture.

Jason:
No special quoins or furniture. I do it all the time, a 5x8 broadside in an 8x12 bias chase. You’re actually locking up a rectangle tipped at an angle inside of another rectangle. Four angle pieces of pine or? would do the trick.

The following are shown in Barnhart Brothers and Spindler, 1925…
Klymax Feeder, 8x, 10x, 12x, C&P’s and a 12x Craftsman C&P, p. 542-543
Bias Chase, includes an explanation, p. 511
McGill Automatic Register Guide, I still have one and use it once in a while just for fun! p. 619.
I’m almost sure the ATF 1923 shows the 8x Peerless! Probably a lot of ‘em still running in Mexico and the Philippines, as we exported one about 15 years ago!
