1851 Great Exhibition: Official Catalogue: Class VIII.: W. and J. Needham
218. NEEDHAM, W. and J., 26 Piccadilly — For S. NEEDHAM, Proprietor.
Patent self-priming gun; in which a lever places the ordinary copper cap on the nipple by the simple action of cocking, the muzzle of the gun being previously lowered to allow a cap to pass from the groove or reservoir (which is formed on each side of the stock from the butt end to the lock, and contains 120 caps) to a recess in the lever.
Patent self-priming gun, with this difference, that the caps are so formed as to allow a closer communication to the charge; and with the addition of an improved safety- apparatus.
Self-priming musket, to use the military flange cap; the construction similar to the preceding, with the exception of the groove or reservoir being down the fore end of the stock, as more suitable for muskets.
Safety stop-lock gun. This invention consists in the introduction of an extra sear to the lock, which acts in unison with the hand-spring of the guard; as soon as the hammer is lifted off the nipple it is caught by the stop or sear in the tumbler of the lock, and the cap cannot be exploded unless the gun is up to the shoulder in the position of firing.
Game registers, double and single guns to load at the breech; intended to combine safety and economy, by improvements in the construction.
Self-loading carbine on the same principle, with the addition of a simple apparatus for self-loading, not liable to get out of order.
