Excerpt from Instructions for Mounting, Using, and Caring for 8-Inch Disappearing Carriages L. F., Model of 1894 for 8-Inch Guns, Models of 1888, 1888 MI, and 1888 MII: Six Plates; June 6, 1903; Revised January 18, 1908; Revised February 10, 1911; Revised October 17, 1916

After the recoil, both pawls on each side will be found engaging the same tooth in each ratchet. Men on each side of the carriage simultaneously raise the long levers, thus raising the inside pawls and, consequently, the crosshead into which they engage, until the distance through which the ratchet has moved is sufficient to enable the fixed pawls on each side to engage the next lower tooth. When this is accomplished the levers are lowered until the movable pawls engage these same teeth, and the operation is repeated until the gun has been lowered the desired amount.

After the gun is loaded it is permitted to rise to the firing posi tion by tripping the pawls. This is done by means of small trip ping bars, maneuvered simultaneously on each side of the carriage. The pawls are so arranged that when the outside pawl is tripped a projection of it bearing on the inner pawl causes the latter to be tripped at the same time. On tripping, the pawls should be forced to the rear until the safety latch engages a pin on the outer pawl, thus preventing the pawls from reengaging the crosshead teeth dur ing the descent of the crosshead. When the crosshead teeth have descended beyond the danger of being engaged by the pawls a lug on the crosshead engages a safety latch, thus releasing the pawls in preparation for engaging the crosshead teeth when the crosshead shall again rise. Stops are placed on the tripping bars, so that they can bear only on the outside pawls; otherwise both pawls will not be tripped.
