FREDERICK WILTON HANLEY PORTER, OF QUEBEC, QUEBEC, CANADA, ASSIGNOR TO SIR CHARLES H. A. F. L. ROSS, OF COUNTY OF BOSS, SCOTLAND.

SIGHT FOR FIREARMS.

Specification of Letters Patent.

Application filed September 27, 1913.

Patented Mar. 3, 1914.

Serial No. 792,235.

To all whom it may concern Be it known that I, FREDERICK \VILTON HANLEY PORTER, a citizen of the Dominion of Canada, residing at Quebec, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Sights for Firearms; and I do 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.

The present invention relates to improvements in sights for fire arms and has for its object to provide an efficient, compact device of a simple construction which may be folded down so as to lie flush with the surface of the gun and which, by a very slight movement will automatically assume the sighting position.

IVith this and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter described and particularly pointed out in the claims.

Referring to the accompanying drawing forming a part of this specification and in which like numerals designate like parts in all the views: Figure 1 is a side elevational view showing the manner of attaching my improved sight to the breech of a gun; Fig. 2 is a plan view on an enlarged scale of the parts shown in Fig. 1; Fig. 3 is a central vertical section on the line 3-3 of Fig. 2. Fig. 4% is a cross section on the line H of Fig. 3, and Fig. 5 is a cross section illustrating a modified form of means for mounting the sight on the barrel of the gun.

1 indicates the breech of the fire arm, and suitably mounted thereon is the sight receiving member or bridge 2. This sight bridge 2 is provided with a dovetail recess 3 for receiving the base 4 of my improved sight as will be apparent from the drawings. The said base 4, is provided with an opening or housing 5 into which the pivoted sighting member 6 may be turned down and housed flush with the base as will be clear from Figs. 2 and 3. Said sighting member is further provided with the notch 7 with which the catch 8 engages to hold it in its depressed position. The catch 8 is slidingly housed in the base 4, is controlled by the spring 10, and is provided With the roughened finger engaging member 11 as shown, by which it may be readily moved backward and forward in the base 4.

12 represents a toe, 13 the pivot of the sight member 6, and 14 a spring engaging said toe and tending normally to maintain said sighting member in its raised or elevated position. 16 represents a set screw or other means for securing the base 1 in the bridge member 2.

I11 the modified form shown in Fig. 5, the bridge is extended around the barrel to form the ring or holding means 20, otherwise the parts are the same as in the preceding figures.

It will thus be seen that my improved sight may be readily attached to or detached from the bridge 2 by simply loosening the screw 16. I am thus enabled to readily substitute any desired sight without inconvenience and as the bases 1 are or may be of a standard size, such sights will need little or no adjustment after being attached to the gun.

It is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to the above disclosure except as may be required by the claims.

\Vhat I claim is 1. In a sight for fire arms the combination of means for securing the sight to the barrel provided with a recess; a readily removable sight base provided with a housing fitting said recess; a sight member pivoted to said base adapted to enter said housing; and a catch for holding said sight member in said housing, substantially as described.

2. In a sight for fire arms the combination of means provided with a slot for securing the sight to the gun; a sight base provided with a housing secured in said slot; a sightmember pivoted to said base adapted to enter said housing; a spring adapted to normally hold said sight member out of said housing and a catch carried by said base adapted to engage said sight mem her and hold it in said housing, substantially as described.

3. In a sight for fire arms the combination of means provided with a slot for securing the sight to the gun; a sight base spring controlling said catch, substantially 19 provided With a housing secured in said as described.
