Jaques ISQ Portable Chess Set, Type 1A
A Jaques ISQ Portable Chess set, Type 1A, or more correctly “In Statu Quo”. This Type 1A Status Quo Chess Set measures 9-1/8″ x 9-1/8″ with red-stained and natural bone chessmen having a King height of 5/8″ by 7/8″ in diameter. The chess set lack its original black leather slip case. The Mahogany chessboard, Chess Pieces and locking mechanism are in very good-to-excellent condition. Jaques patented the In Statu Quo Travel Chess Set in 1853.
The chessmen have a metal peg inserted into each of their bases to enable the locking system to operate. The Jaques ISQ Portable Chess Set features a hinged folding board with an ingenious patented locking system. By depressing two white buttons located at each half of the chess board, the pieces are locked in place so the game can be halted midway and stored for a later date with the position kept intact. An additional inside button unlocks the pieces. There is a brass slide on either side which locks the chessboard in the open position.
The name “In Statu Quo Chessboard” is imprinted along one edge of the frame, and “Jaques Patentees London” printed on the opposite side. The Rosewood and Holly chessboard is housed within the Mahogany frame. The Jaques ISQ Portable chess set has its original black leather case with a silver-embossed Jaques’ manufacturer’s Emblem. The chess pieces is in excellent condition. The red stain is still strong. The leather case is in good condition.
The Jaques patent application is dated 1st July 1853 and was submitted on 2nd July. The patent was granted on 16th August 1853. Jaques produced In Statu Quo portable chess sets in four basic sizes. These were available in either Red-stained and natural Bone or African ivory. Each chess set came housed in a Black leather carrying case with a lockable flap covering the small end of the case. The lockable outside of the flap had a gold embossed Jaques manufacturer’s emblem. To facilitate remembering which side had the move when the game was paused, there was a slider on the underside of the flap which would show either a red or a white swatch. Each case originally had a pull-ribbon to aid removal of the chess set. Few of these ribbons survived.
- The most common of the In Statu Quo chess sets, measured 9-1/8″ x 9-1/8″ with bone or ivory chessmen. They had a King height of 5/8″ by 7/8″ in diameter. These came in two black leather case configurations. One was a rather typical parallelepiped, (Type 1A), which is the configuration of this set. The second, , had a rounded spine with a small flap atop the spine to insert the captured chessmen (Type 1B). They came with keyed locks or simple clasps like this set.
- The next size, and probably the most practical, is the Type II. It measured 11-1/2″ x 9-1/8″ and used the same bone or ivory pieces as the smaller In Statu Quo sets. The major difference between this and the smaller sets was the extra field at each end to store and secure the captured chessmen. It had only one case configuration. That was a black leather parallelepiped with a lockable flap.
- There were two larger size In Statu Quo portable chess sets. One measured 12-5/8″ x 12-5/8″ with bone or ivory chessmen having a King height of 3/4″ by 1″ in diameter. This was the Type III In Statu Quo. There was only one black leather carrying case configuration.
- The largest of the In Statu Quo Travel Chess sets measured 16-5/8″ x 12-5/8″ with the same bone or ivory chessmen as the set above. This was the Type IV In Statu Quo. These came in a rather distinctive leather case configuration. It was a typical parallelepiped, but with its lockable flap covering the long face of the case. This is the set pictured in the “Death Photo” of Alexander Alekhine.
