M. L. CAMPBELL. I HAMMER GUARD FOR FIREARMS.

No. 521,583. Patented June 19, 1894 wuawtoz UNITED STATES PATENT OFFICE.

MARY LOUISA CAMPBELL, OF NOYAN, CANADA.

HAMMER-GUA D. FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 521,533, dated June 19, 1894.

Application filed January 27,1894. serial No. 498,226. (No model.)

To all whom it may concern.-

Be it known that I, MARY LOUISA CAMP- BELL, a subject of the Queen of Great Britain, residing in Noyan, Province of Quebec, Canada, have invented certain new and useful Improvements in Safety-Guards for Firearms; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a safety guard for the hammer of a pistol or gun, orfire-arms generally, as has for its object to provide a simple and efiective means for preventing the hammer from being accidentallyor unintentionally operated.

With these and other objects in view, the in-. vention consists of the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings: Figure 1 is a perspective view of a part of a pistol, showing the improved device applied over the hammer thereof. Fig. 2 is a transverse vertical section of the device as applied. Fig. 3 is adetail perspective view of the device disconnected.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

Referring to the drawings, the numeral 1 designates a hammer of a pistol or gun. Removably fitted over the hammer is a cap 2 which is formed of such shape as to conform to the contour of the part or parts of the pis- 1:01 or gun adjacent to the hammer. Thiscap snugly fits over the hammer and guards the same against engagement with any exterior object.

' The use of the device will prevent great injury and loss of life, which is consequent upon the accidental or unintentional discharge of fire-arms by a manipulation carelessly, of the hammer, but when it is desired to use the fire arm, said cap can be readily removed and leave the same free for use.

The cap is of such size and material as to snugly fit over the hammer and adjacent portion of the pistol without danger of dropping 0E, and a chain or analogous device 3 is connected to the cap 2 and the pistol or gun in order to hold the said cap in proper connection with the firearm at all times.

It will be understood that the cap can be made large enough to cover double hammers, or he slipped over the trigger and its guard.

' The cap is formed with opposite conical lugs or projections 4, extending inward from the lower front portion of the same, which are adapted to rotatably engage opposite, similarly fo'rmed recesses 5 on the side of the fire arm. This construction prevents any tendency toward accidental removal or stripping off of the cap, and also permits the latter to be turned back on the lugs or projections which serve as pivots.

Having thus described the invention, what is claimed as new is r In combination with a fire arm having recesses in the opposite sides thereof, and a hammer, of a cap adapted to be mounted over the hammer and conforming in shape to the adjacent portions of the fire arm, the lower front portion of the cap being provided with inwardly extending lugs or projections adaptedto engage the recesses in the sides of the firearm, and a chain attached to the said cap and to the fire arm, substantially as and for the purposes specified.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

MARY LOUISA CAMPBELL.
