In order that the guides this purpose. Further, both the rails ncan for the keyboard shall not be in the way, it be rigidly connected together to form a is preferable for them to be movable or tiltframe-like structure, by means of a transtive position when not so required for supporting the keyboard. Rails slidable independently of the keyboard and movable in and out of the machine frame could also be used as guides.

The direction of movement of the keyboard need not necessarily be directly fore and aft, for, by arranging the supporting rails at the desired angle in the machine frame, the keyboard may be moved obliquely frontwise so as to obtain at the same time a little more space at the side. A saving in lateral space would also result in such a case because when the keyboard is moved obliquely towards the front and towards one side, the lateral movement need be only suflicient to enable free access to be had to all parts of the keyboard.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. Matrix composing and line casting machine in which the keyboard can be moved out of its operative position for the purpose of making it more accessible, characterised by the fact that the keyboard is mounted on the machine frame so as to be movable in fore and aft direction towards and away'from the operator.

2. Matrix composing and line casting machine according to claim 1, characterised by mutually engaging members on the keyboard and on the machine frame, which retain the former on the latter with a capacity for said former to be moved in fore and aft direction relatively to the latter.

. 3. In a keyboard controlled matrix composing and line casting machine, the combination with the keyboard, of rails fast thereto and extending in fore and aft direction, and rollers on the machine frame, supporting the rails with a capacity for said rails to be moved in the direction of their length.

4. In a keyboard-controlled matrix composing and line casting machine in which the keyboard is movable in fore and aft direction relatively to the machine frame, the combination with the keyboard, of rails fast thereto and extending in fore and aft direction, and rollers on the machine frame acting on the rails to prevent them and the keyboard from overbalancing when the keyboard is in its foremost position.
