    Arab Press Register

    In the Sum­mer of 2013 I set up a form to col­lect details of Arabs press­es around the world.  There are 19 press­es reg­is­tered at the moment run­ning in age from about 1892 to 1907.

    If you run an Arab and are will­ing to share the details, please com­plete the Arab Reg­is­ter.  In the com­ing months, I’ll organ­ise a way of shar­ing the con­tact details of Arab users.

    Taking an Arab Apart

    This is an account of dis­man­tling a Crown Folio Arab Plat­en. The machine is ear­ly (Ser­i­al Num­ber 1086 c. 1892) but has had a num­ber of safe­ty fea­tures fit­ted. The guide below shows the major steps and will be added to. There’s a spe­cial sec­tion at the foot of this page about the brak­ing sys­tem.

    The main body of the Machine

    The start­ing point: a com­plete Arab

    Ink­ing Disk Removed (remem­ber to replace the bolt under­neath).

    Feed board removed

    One of the ink­ing arms removed. Remem­ber that they are under the pres­sure of a spring so you have to keep hold of the arm as you release. In prepa­ra­tion for this you should have removed the rollers and stocks; and also removed the met­al bar which links left and right roller arms: keep this safe!

    Over-arch­ing guard removed by unbolt­ing one site of the guard bars (not pic­tured)

    There are two strong springs which force the front plat­en towards to back plat­en. These need to be un-hooked while the front plat­en is almost ver­ti­cal. The two col­lars and hooks on the plat­en site need to be loos­ened so that the bar can be slid out lat­er on.

    The two bolts on the left of the front plat­en must be removed so that the front plat­en is held only on the sup­port­ing bar. Remove the sup­port­ing bar and lift the front plat­en out. This is fair­ly del­i­cate as it will still con­tain the frisket motion.

    Arab: front plat­en removed

    The Arab wheel can now be slid from left to right and removed from the machine

    The rock horse’ is now removed. This is the U‑shaped met­al cast­ing which forces the front plat­en upwards. This rests in two slots is the frame cov­ered by two semi-cir­cu­lar cast­ings bolt­ed down.

    The back plat­en is now removed as a sin­gle large unit: includ­ing the plat­en and the sup­port­ing cast­ing. This is very heavy but will save trou­ble because the back plat­en will not have to be re-adjust­ed. The eccen­tric is also removed: this is the rod which holds the impres­sion lever.

  • History of the Jobbing Platen

    History of the Jobbing Platen

    After the 1830s, the growth of the postal ser­vice and the expan­sion of com­merce led to growth in demand for small, print­ed arti­cles.  The Job­bing Plat­en met this need for the print­er: being quick­er than the ear­li­er hand press­es; and more suit­ed to small work than cylin­der press­es. It’s tempt­ing to think that the plat­en press sim­ply appeared — ful­ly formed — but there were many small advances that made that style of press pos­si­ble. Daniel Tread­well, an Amer­i­can, sought an 1818 patent to pro­tect his design for a mod­i­fied hand press that used foot pow­er (like a trea­dle) to deliv­er the impres­sion.  He trans­ferred the inven­tion to Eng­land and the firm of Baisler and Napi­er made the machine at their works at Lloyds Court, Crown Street, Soho; but only one is report­ed to have been sold.  The rotat­ing ink disc was invent­ed between 1819 and 1820 by Sir William Con­gereve for secu­ri­ty print­ing.  John Kitchen of New­cas­tle Upon Tyne patent­ed the ver­ti­cal forme in 1834.  It seems the machine would not have been com­mer­cial­ly suc­cess­ful, but was designed in the style of goth­ic church fur­ni­ture”.

    The First Usable Platen

    Stephen Rug­gles, from Boston USA, devel­oped the Engine press in 1839 but the bed and plat­en were hor­i­zon­tal.  Despite this, the press claimed 1,200 impres­sions per hour.  It was his devel­op­ment of 1851 of the Card and Bill­head Press” that opened the era of the first usable plat­en: this relied on his strange ink­ing mech­a­nism.  The approach is to have a large cylin­der, flat on one side for the type.  The cylin­der is cov­ered in ink and as the rollers pass around it, they draw ink from the cir­cu­lar part of the cylin­der and deposit it on the forme.  This press was made in Britain by the Birm­ing­ham Machin­ist Com­pa­ny as the Invic­tus and also Fur­ni­val and Com­pa­ny of Red­dish.  The prin­ci­ple was lat­er adapt­ed by Adana for their T/P48.

    The Modern Platen

    The pro­to­type plat­en press was devel­oped by George Gor­don of New York.  His ear­ly press (1851) was named The Alli­ga­tor because of its rep­u­ta­tion of crush­ing limbs of those feed­ing the press.  This first ver­sion had a fixed ink­ing pan­el, it was 1856 before he added the rotat­ing ink­ing disc.  In 1872, the throw off” was added: a mech­a­nism to allow the oper­a­tor to dis­able the impres­sion when a sheet had been mis-fed, for exam­ple.  Again, the idea was not new hav­ing been patent­ed in 1852 by James Young of Philadel­phia. Crop­per of Not­ting­ham began to make Gor­don’s press­es under the name Min­er­va, but the term Crop­per to define that type of press became com­mon­place.  Oth­er, local­ly designed, press­es used Gor­don’s idea like the Arab from Hal­i­fax.

    The Parallel Platen

    Improv­ing on the clam shell” approach, Mer­rit Gal­ly of New York devel­oped a press in 1859 called the Uni­ver­sal which brought the bed and the plat­en togeth­er with a par­al­lel impres­sion.  This was improved by the Vic­to­ria and Phoenix press­es.  In the UK, Green­wood and Bat­ley of Leeds sold a very sim­i­lar press under the name Sun; Daw­son’s of Otley the Mitre; and Har­rild of Lon­don the Fine Art Brem­n­er.

    The Powered, Automatically-Fed Platen

    Know­ing that the effort of a boy could not be sus­tained to thou­sands of impres­sions each hour, work began on mak­ing effi­cien­cies of space and pow­er.  In 1893, Har­rild of Lon­don cre­at­ed a plat­en press run­ning back-to-back: two mov­ing platens each print­ing against a sin­gle, two-sided, fixed bed. With steam and elec­tric pow­er, the next chal­lenge was to feed the press with paper. A grip­per was patent­ed by God­frey in the 1880s, and an auto­mat­ed feed for US Chan­dler and Price press­es was being sold by 1913.  Per­haps most known to us in the UK is the inven­tion of Gilke, a Hei­del­berg Engi­neer, who cre­at­ed the wind­mill feed in 1912 which was incor­po­rat­ed in to the 1925 Hei­del­berg Auto­mat­ic Plat­en.

  • Platen Presses

    Platen Presses

    Plat­en press­es here include press­es pow­ered by foot, steam or elec­tric­i­ty. Their main char­ac­ter­is­tic is that paper is fed into a jaw’ with the type on one side and paper on the oth­er. Some have auto­mat­ic feeds, so that paper does­n’t have to be sup­plied by hand for each impres­sion.

    These machines formed the main­stay of job­bing print­ers let­tr­press work up to the 1980s, and are used today by print­ers for cut­ting, creas­ing and num­ber­ing.

  • Buying and Running an Arab

    Buying and Running an Arab

    The Arab is a mix of cast-iron frame; steel rods and brass. Machines were fet­ed for their reli­a­bil­i­ty and stur­di­ness. They have to be kept well-oiled and clean. When buy­ing, look out for –

    • cracks in the frame (dif­fi­cult to repair)
    • jud­der on open­ing the plat­en (could be a symp­tom of sig­nif­i­cant wear in the bear­ings)
    • any loose­ness of the plat­en: test by try­ing to pull the plat­en apart from the forme when closed up

    The machine body was paint­ed in Roy­al Blue’ but debate con­tin­ues about the exact shade, and whether dif­fer­ent shades were used. The brass roller arms were the only part of the machine to be paint­ed Pil­lar Box Red’. While the machine alone is great, also look out for –

    • man­u­als or erec­tion instruc­tions
    • addi­tion­al chas­es — the Arab came with full-size and but­ter­fly’ chas­es; or even this slant­ed chase
    • roller stocks and bear­ers (per­haps for a third roller)
    • spare parts

    Dismantling an Arab

    This is a rever­sal of the erec­tion instruc­tions and is based on expe­ri­ence. Remem­ber to keep parts togeth­er as far as pos­si­ble (eg replace nuts on bolt ends as soon as they are removed) and keep things in whole, com­plete ele­ments — like the brak­ing mech­a­nism — remove this as one unit.

    1. Ink­ing mech­a­nism
    2. Feed boards
    3. Tym­pan — by remov­ing the blan­ket rod and wire
    4. Forme Ink­ing Equip­ment
      1. Ink­ing roller bar, ink­ing rollers and run­ners
      2. Roller brass­es — care­ful of the springs
      3. Swinger bars which hold the
      4. Ink­ing disk and bear­er
      5. Ink disk pick lever
    5. Safe­ty Guard
    6. Arab Wheel should be loos­ened
    7. Spring and Plunger to hold the Chase on the back plat­en
    8. Con­nect­ing Rods
    9. Back Plat­en
      1. Low­er the back plat­en
      2. Remove the bolts from the foot of the back plat­en legs
    10. Fly­wheel — remove with nut (may have left-hand thread)
    11. Trea­dle and con­nect­ing rod
    12. Frisket mech­a­nism
      1. Strap Guide Rod
      2. Blan­ket and Frisket shafts
      3. Frisket springs
    13. Die Plate and Bush­es — this is the thing which holds the rock-horse against the plat­en
    14. Remove springs from the Plat­en Hooks
    15. Front plat­en — by remov­ing the rod, and col­lect­ing the plat­en hooks
    16. Remove the Arab wheel all togeth­er
    17. Impres­sion adjuster
    18. Eccen­tic shaft (con­nect­ed orig­i­nal­ly to the impres­sion adjuster)
    19. Rock horse
    20. Crank shaft — orig­i­nal­ly con­nect­ed to the fly­wheel
    21. Clutch and trip link
    22. Remove the bolts on the stays
    23. Take one side from the oth­er
