Cylinder \Cyl"in*der\ (s?l"?n-d?r), n. [F. cylindre, OF.
cilindre, L. cylindrus, fr. Gr. ky`lindros, fr. kyli`ndein,
kyli`ein, to roll. Cf. {Calender} the machine.]
[1913 Webster]
1. (Geom.)
(a) A solid body which may be generated by the rotation of
a parallelogram round one its sides; or a body of
rollerlike form, of which the longitudinal section is
oblong, and the cross section is circular.
(b) The space inclosed by any cylindrical surface. The
space may be limited or unlimited in length.
[1913 Webster]

2. Any hollow body of cylindrical form, as:
(a) The chamber of a steam engine in which the piston is
moved by the force of steam.
(b) The barrel of an air or other pump.
(c) (Print.) The revolving platen or bed which produces
the impression or carries the type in a cylinder
press.
(d) The bore of a gun; the turning chambered breech of a
revolver.
[1913 Webster]

3. The revolving square prism carrying the cards in a
Jacquard loom.
[1913 Webster]

{Cylinder axis}. (Anat.) See {Axis cylinder}, under {Axis}.


{Cylinder engine} (Paper Making), a machine in which a
cylinder takes up the pulp and delivers it in a continuous
sheet to the dryers.

{Cylinder escapement}. See {Escapement}.

{Cylinder glass}. See {Glass}.

{Cylinder mill}. See {Roller mill}.

{Cylinder press}. See {Press}.
[1913 Webster]

The set of {tracks} on a multi-headed {disk} that
may be accessed without head movement. That is, the
collection of disk tracks which are the same distance from the
spindle about which the disks rotate. Each such group forms
the shape of a cylinder. Placing data that are likely to be
accessed together in cylinders reduces the access
significantly as head movement ({seeking}) is slow compared to
disk rotation and switching between heads.
