Thus fitted, when the gun is run in and levelled, breechings must be long enough to allow the muzzle of the gun to come a foot inside of the upper port-sill, if the breadth of the vessel will allow it. ❋ United States. Navy Dept. Bureau Of Ordnance (N/A)
When the breech of the gun is above the port-sill, hook the garnet and the thwart-ship-tackle to the cascabel, and bowse on both. ❋ United States. Navy Dept. Bureau Of Ordnance (N/A)
When the slings bear hard on the upper port-sill, lower the gun-purchase, and bowse on the garnet until the breech is high enough for the trunnions to clear the cap-square bolts in the carriage; then bowse on the thwart-ship-tackle until the trunnions are over the trunnion-holes, lowering the purchase as required to bring the gun into its place. ❋ United States. Navy Dept. Bureau Of Ordnance (N/A)
Bring the gun under the yard and sling it as follows: place one bight of the slings under the neck of the cascabel, and pass the lashing which is attached to the slings round the chase, at such a distance from the trunnions as will allow them to go into the trunnion-holes without bringing too great a pressure of the slings against the upper port-sill. ❋ United States.

For IX-in. guns, the port-sill should not be less than 20 inches in height, and no port-sill less than 16 inches; otherwise, the carriages will not give sufficient elevation, and the position of the Gun ❋ United States. Navy Dept. Bureau Of Ordnance (N/A)
The Handspikemen raise the breech to free the quoin; the 2d Captain withdraws it and the bed; the Handspikemen lower the breech upon the axletree, so that in case the gun should break adrift, the muzzle will take the upper port-sill; and the Port-tacklemen lower the port-lid. ❋ United States.

When home, the men run the gun out as quickly as possible; the Captain of the gun clears the vent, primes in running out, points and fires in the usual manner, but as rapidly as is consistent with a good aim, taking care that the muzzle is clear of the port-sill, and on lower decks that the port is triced up clear of the explosion. ❋ United States.

One end of a tripping-line is fastened to the middle of the toggle, and the other to the breeching-bolt in the side of the ship; by this arrangement the toggle is tripped from its place at the commencement of the recoil, and the muzzle is raised so as to clear the port-sill by the preponderance of the breech. ❋ United States. Navy Dept. Bureau Of Ordnance (N/A)
Hook the garnet and haul it taut, so as to raise the breech of the gun as much as the port-sill will permit; hook or toggle the gun-purchase, and sway away. ❋ United States. Navy Dept. Bureau Of Ordnance (N/A)
The ports were to be rather "deepe uppe and downe" than broad in the traverse, and it was very necessary that the lower port-sill should not be too far from the deck, "for then the carriage muste bee made verye hygh, and that is verye evill" (_Bourne_). ❋ John Masefield (1922)
Jean's enormous corporation being then elevated, by means of capstan bars and handspikes, was brought on a level with the port-sill. ❋ Hall, Basil, 1788-1844 (1862)
Paddy had seized one of his legs, and was tugging away with might and main; while the Spaniard, with his other foot on the port-sill, had nearly effected his purpose, notwithstanding the Irishman's desperate efforts to prevent his escape. ❋ William Henry Giles Kingston (1847)
The gun was carefully levelled; and, when they were all ready, Woodford gently put the helm up; the schooner gradually fell off from the wind, and presently there was a deafening explosion, accompanied by a jarring concussion which shook the schooner from stem to stern; and as the smoke drove away to leeward we saw a jet of spray a dozen feet high shoot into the air as the ball struck the crest of a wave, and in another instant a white patch of naked wood appeared exactly in the centre of a port-sill, showing where the shot had hulled the frigate. ❋ Harry Collingwood (1886)
