1875 Minutes Proc. Inst. Civil Engineers 40 356 Another instrument had been tried, also invented by M. Marcel-Deprez, and called by him an accelerograph, which, like the first, consists of a piston moving freely in a tube, and receiving directly on its base the force of the explosion.
1913 Jrnl. Franklin Inst. 175 614 Having found the stresses in level uniform flight. they may be estimated for accelerated motion..by first recording these sudden changes of velocity by means of an accelerograph.
1921 Bull. Seismol. Soc. Amer. 11 56 Owing to deficiencies in one or another part of the complicated mechanism of the accelerograph..records of earth-waves were not obtained invariably..at the origin.
1956 Atlantic 19 Dec. 19/1 A device called the Accelerograph, something like a baby seismograph, is turning this art into a science.
1967 tr. M. Baranova & Y. Veltistov in M. Morton Harvest Russ. Children's Lit. (1970) 251 There was the faithful companion of the flyer, the accelerograph, whose leaping graph tells of the invisible forces of gravity.
2003 Science 30 May 1422/2 A recent study compared GPS and accelerograph data from the Hector Mine earthquake.
