1 and 2 carry the prypole, 3 and 5 the right cheek, 4 and 6 the left, 7 the windlass and fids, 8 and 9 the blocks and tackles, 10 the handspikes, &c.
To Set up a Gin.
1 and 2 put a common handspike through the ring, near the foot of the prypole, at which they lift; 3 and 4 steady the cheeks, by placing each a handspike against the lower cross bar; 5, 7, and 9 lift the right cheek; 6, 8, and 10 the left cheek; 11 gives directions. The tackles must be hooked on before the gin is raised.
To work a Gin.
1 and 3 man the right handspikes of the gin; 2 and 4 the left; 5, 6, 7, and 8 hold on the fall, and pull in the slack; 9 and 10 steady the gun, 9 at the muzzle, 10 at the breach. The tackle hook must be fixed directly over the dolphins, if any, or a little behind the trunnions.
In heaving, when the ends of 1 and 4 handspikes come as low as their knees, 2 and 3 put theirs into the upper holes of the windlass, and 3 gives the word Fetch, upon which 1 and 4 clear their handspikes from the windlass, and 1 gives the word Heave; 2 and 3 then bear down their handspikes, and remain fast till 1 and 4 having taken their fresh purchase, 1 gives the word Fetch, when 2 and 3 clear their handspikes, and 3 gives the word Heave; and so on alternately, till the gun is at its proper height, when the handspikes in the upper holes are made to rest against the upper cross bar, and 5 makes fast the fall to the lower cross bar; and if required to lower the gun, eases the fall off from the windlass; 5, 6, 7, and 8 move the carriage, as required, under the gun.
Exercise of the Sling Cart.
The men for the service of the sling cart are numbered from 1 to 7; the noncommissioned officer being No. 7; No. 1 and 2 sling the gun. The gun must be laid with 1 trunnion touching the ground, and the sling passes diagonally round the gun; being before one trunnion, and behind the other; and that end of the sling which goes round the lower side of the gun must be the end to be acted on by the windlass; as by that means the trunnions become horizontal when the gun is raised; No. 1, 3, and 5 man the right lever; 2, 4, and 6 the left lever; and upon the word from the noncommissioned officer they heave together: the noncommissioned officer then directs left hand lever hold on, right lever fetch; the right lever takes a fresh purchase: then, right lever hold on, left lever fetch; the left lever takes a fresh purchase; they then heave together again. When the gun is high enough, 7 puts in the pall; 1 and 2 take out the levers, and put in the prypole; 3 and 4 raise the breech of the gun with two common handspikes, and 5 and 6 lash it to the prypole: 1 and 2 then lay their levers along side the prypole, and 3 and 4 their handspikes on the top of them, which 5 and 6 lash all fast together.
