COLT GUN.

SPECIFICATION forming part of Letters Patent No. 680,327, dated August 13, 1901. Application filed October 24, 1900. fleriel No. 34,148. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM GEORGE HAY, a citizen of England, residing at 201 Northill street, Liverpool, in the county of Lancaster,

England, have invented certain new and usef ul Improvements in Colt Guns or other Guns in which the Lock Mechanism is \Vorked by Lateral Escape of Gas, (for which I have applied for a patent in Great Britain, dated July 10, 1900, No. 12,426,) of which the following is a specification.

My invention relates to means of adapting 'for blank firing a Colt gun or. other gun the lock mechanism of which is worked by lateral escape of gas. This is effected as will be described with reference to the accompany' ing drawing, in which the figure is a longitudinal section showing the front portion of a Colt gun, showing in elevation the 0perating-lever, which is worked by lateral escape of gas.

On the muzzle of the gun is screwed a sleeve a, having several lateral holes I), and is screwthreaded to receive a fiat-ended setting sc'rew 0, provided with a lock-nut d. This screw is adjusted with its end so close to the muzzle as to throttle the outlet there sufficiently to cause within the barrel in blank firing the,

pressure of powder-gas necessary to work the lock-operating lever e in the same manner as when a bullet passes along the here. The degree of throttling for this purpose can be ascertained by trial, and the screw 0 being once adjusted is prevented from shifting by the lock-nut d. In order to suit the cartridge for blank fire to the lock mechanism, it may be gas within the bore, have a piston or plunger so acted on, and for these guns blank-fire cartridges with wooden plugs, as above described, can obviously be employed.

Having thus described the nature of this in- J venti'on and the best means I know for carrying the same into practical effect, I claim- 1. The combination'with a gun having lock mechanismarrangedto be operated by lateral escape of gas, of a cap secured to the muzzle andhaving a gas-passage through it and means for regulating the escape of gas through said passage; substantially as described.

- 2. In combination with a Colt or other gun having its lock mechanism workedby lateral escape of gas, a sleeve screwed on the muzzle with lateral passage and an adjustable throttling-screw for causing sufficient gas-pressure in the bore to work the lock mechanism in blank firing, substantially as described.

, In testimony whereof I have hereunto set my'hand in presence of two subscribing wit- UGSSGS.

W. G. HAY.
