LETTERS PATENT to Walter William Colley of Camberwell in the County of Surrey for an Invention of Improvements in revolving fire-arms

(Void by reason of the Patentee having neglected to file a Specification in pursuance of the conditions of the Letters Patent.)

PROVISIONAL SPECIFICATION left by the said Walter William Colley at the Office of the Commissioners of Patents on the 30th October 1883.

Walter William Colley of Camberwell in the County of Surrey, “Improvements in revolving fire-arms.”

My Invention relates to an improved self cocking revolving gun for military or sporting purposes, the gun being cocked, fired and revolved by one and the same means. The revolving cylinder containing any convenient number of charge chambers turns upon a tubular axis, and is revolved by a pawl and ratchet motion actuated by the hammer as in an ordinary revolving pistol. Through this revolving axis passes a sliding rod which is jointed to the hammer at its rear end and at its front end to a lever handle pivoted beneath the barrel of the gun in a suitable position for being worked by the left hand whilst the gun is held up to the shoulder in position for firing said lever acting at once as a means of supporting the gun in that position and at the same time as a means of cocking and as a trigger for firing the gun the ordinary trigger being dispensed with. The cocking is effected through the medium of the sliding rod above mentioned whilst the firing is effected through the agency of another sliding rod jointed to the said lever (at the opposite side of its centre of oscillation to that at which the cocking rod is jointed.) said rod working through a suitable guide and abutting against the end of a corresponding rod in line therewith which is jointed to the scar. Thus by moving the hand lever to and fro the hammer is cocked and the cylinder revolved by the motion in one direction and the gun is fired by the motion in the other direction. With the said hand-lever or with the sliding rod for cocking the hammer may be combined a motion for extracting the spent cartridge cases if desired.

With this gun the whole of the charges may be fired in very rapid succession without even taking the gun down from the shoulder.

In the case of sporting guns I may provide the ordinary trigger action for firing the gun in lieu of handlever above mentioned if preferred.
