1891 Cent. Dict. Spline, a flexible strip of wood or hard rubber used by draftsmen in laying out broad sweeping curves, especially in railroad work.

1904 Drapers' Co. Res. Memoirs XIII. 12 The curves..were plotted with our coordinatograph for a series of values of k or r on a large scale, drawn in with a spline and integrated with a Coradi compensating planimeter.

1953 A. H. Robinson Elem. Cartogr. v. 83/1 For larger curves, the defining points of which are far apart, a flexible curve or a spline with weights is more satisfactory.

1892 P. H. Emerson Son of Fens 204 A spline is a ten and a half foot measure.

2. technical. A rectangular key fitting into grooves in a shaft and wheel or other attachment so as to allow longitudinal movement of the latter. Now esp. such a key that is formed integrally with the shaft; also, a corresponding recess in a hub along which the key may slide.

1952 F. J. Camm Newnes Engineer's Ref. Bk. (ed. 5) 854 The efficiency of a spline for driving purposes is measured by the amount of contact made by the male and female splines.

1966 G. W. Michalec Precision Gearing vii. 324 Generally, involute internal and external teeth are mated, but non~involute splines are also suitable.

1979 Industrial Fasteners Handbk. i. 318 There are two basic forms of spline—straight-sided splines which may number 4, 6, 10 or up to 16 splines equally distributed around the circumference of a shaft, and serrated splines which are in the form of adjacent triangular teeth.

3. Mathematics. Also spline curve. A continuous curve constructed so as to pass through a given set of points and have continuous first and second derivatives.
