REAR SIGHT FOR GUNS.

SPECIFICATION forming part of Letters Patent No. 666,665, dated January 29, 1901.

' Application filed October 10, 1900. Berial No. 32,596. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES H. GRIFFITH, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Rear Sights for Guns; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact descrip- IO tion of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a plan view of one form which a sight constructed in accordance with my'i'n- I5 vention may assume; Fig. 2, a side view thereof; Fig. 3, a sectional view showing the application of my improved sightto a gunbarrel; Fig. 4, a corresponding View showing the application of my improved sight to an octagonal gun-barrel to which the sight is conformed in shape; Fig. 5, a broken view in central longitudinal section, showing one mode of securing my improved sight to a gun barrel; Fig. 6, a corresponding view showing a different Way of securing the sight to a gun-barrel.

My invention relates to an improved rear sight forguns, the object being to produce an extremely simple, easily-adjustable, convenient, and effective sight constructed with particular reference to fewness of parts and cheapness of manufacture.

WVith these ends in View my invention consists in a sight having certain details of con- 3 5 struction and combinations of parts, as Will be hereinafter described, and pointed out in the claims. I

In carrying out my invention I strike up from a suitable sheet metal blank a sightbody comprising a yielding shank A, a horn A, and a head A The said head A is made integral with and located at the forward end of the said shank and formed with a centrally-arranged and threaded screwehole B and provided upon its opposite edges with two downwardly turned retainingflanges C and D, extending parallel With each other and withthe longitudinal axis of the said shank. If desired, one of these flanges may These flanges perform the function of clasping the gun-barrel, to which therefore they should by preference be conformed in cross-sectional shape. If the barrel is a circular barrel, the head and flanges will be bent to conform thereto, as shown in Fig. 3, while if the barrel is an octagonal barrel the flanges and head will be bent to conform thereto, as shown in Fig. 4. The screw-hole B before mentioned receives the shank E of a short screw, the beveled head F of which is constructed in the pitch of its bevel to fit tightly into a dovetailed or undercut slot G, formed transversely in the top of the gun-barrel H.

In securing a sight-body to the gun-barrel the beveled head of the screw is introduced into the slot G from one end thereof and moved into the longitudinal center of the slot. The said sight-body is then placed upon the gun-barrel and the screw-hole B brought into alinement with the shank of the screw. A screw-d river is now inserted into a slot 6, formed in the shank E of the screw,after which the screw is turned, so as to draw the head of the sight-body down firmly upon the gun-barrel, the sides of which are clasped by the retaining-flanges of the head. The screw is of course kept by the bevel of its head from lifting out of the slot, in which, however, it is freeto turn. The horn A aforesaid is formed at and integral with the rear end of the shank A of the sight-body and contains the usual V-shaped sight-notch I, terminating in a small sight-hole J. This notch is raised or lowered 8 according to the requirements of the user of the arm by means of a small adjusting-screw K, mounted in a small threaded opening L, formed in the extreme rear end of the shank A and therefore at a point directly in front 0 of the horn A, which protects it. The lower end of this screw impinges upon the top of the gun-barre1, which constitutes a point of purchase for lifting the horn A by springing the shank A when required. 9 By providing my improved sights with screws like the screw E, I may apply them to guns primarily constructed for the reception of ordinary sights and thereto adapted by forming their barrels with transversely-ar- I00 ranged dovetailed slots for the reception of dovetailed ribs formed at the forward ends barrel 0.

of the sights. It is apparent, however, that my improved sight may be attached in other and still cheaper ways-as, for instance, as shown in Fig. 6 of the drawings, in which the sight-body has a shank A, a horn A, and

a head A having retaining-flanges O andv D, and therefore corresponding to the sightbody shown in the other figures of the drawings; but this sight-body is secured in place by a simple screw M, passing downward through its head A and into an ordinary threaded screw-hole N, formed in the gun I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a rear sight forguns, the combination with a sight-body formed from a single piece of sheet metal and having a shank, an upturned horn located at the rear end thereof, and a head located at the forward end of the shank and having a downwardly-turned retaming-flange forclasping the gun-barrel; of means for connecting the sight-body through its head to the gun-barrel, and means applied to the rear end of the said shank of the sightbody for vertically adjusting the said horn.

2. In a rear sight forguns, the combination with a sight-body formed from a single piece of sheet metal and having a shank, an upturned horn located at the rear end thereof, and a head located at the forward end of the shank, formed with a screw-hole and having a downwardly turned retaining flange for clasping the gun-barrel; of a screw havinga short shank adapted to enter the said screwhole and formed witha beveled head adapted to be entered into a transversely-arranged dovetailed slot formed in the gun-barrel.

3. In a rear sightforguns, thecombination with a sight-body formed from a single piece of sheet metal, having ashank, an upturned horn located at the rear end thereof, and a head located at the forward end of the said shank, formed with a threaded screw-hole, and having two downwardly-bent retainingflanges for vlasping the gun-barrel, to the shape of which they are conformed, of a screw having a short shank adapted to enter the said screw-hole, and formed with a beveled head adapted to be entered into a transverselyarranged dovetail slot formed in the gun-barre], and an adjusting-screw mounted in the said shank just in front of the said horn, and impinged upon the gun-barrel for springing the shank and vertically adjusting the horn.

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

CHARLES H. GRIFFITH.
