' To all whom it may concern:
Be it known that I, FRANK F. BURTON, a citizen of the United States, residing at Mount Carmel, in the county of New Ha ven and State of Connecticut, have invented a new and useful Improvement in Ventilated Sight-Ribs for Si'ngle-Barirel Firearms; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

My invention relates to an improvement in that class of ventilated sight-ribs for single-barrel firearmsin which the rib is slidably attached to the barrel for relative longitudinal movement with respect thereto, except at one point between the endso'f the barrel where the rib and the barrel are rigidly secured together, the object of my present invention being to simplify and cheapen devices of the character specified.
With these ends in view, my invention consists in certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.
In carrying out my invention, as herein shown, I employ a sight-rib 2 provided at regularly spaced points upon its lower face with a seriesv of spacing-blocks 3 having 'flat upper faces and concave lower faces, the latter conforming in curvature to the curvature of the barrel 4-, which is formed in its upper face with a series of dovetail keyhole recesses 5, the parallel sideand end walls of the narrow forward ends of which are undercut. The spacing-blocks 3 are fastened to the lower face of the rib 2 by means of dovetail rivets 6, so characterized on account of having beveled circular heads 7 at their lower ends, these heads being bear upon the lower faces of the blocks from which the said heads project or offset. The said rivets are passed upwardly through rivet-holes 9 in the blocks 3 and thence upward through rivet-holes 10 in the rib .2, the upper ends of the holes 10 being counterbored as at 11 to permit the upper ends of the shanks of the rivets to be swaged down flush with the upper face of the rib.
In mounting the rib upon the barrel, the projecting heads 7 of the rivets are entered into the enlarged rear ends of the dovetail recesses 5, after which the rib is moved longitudinally forward, whereby the said heads are entered into the forward ends of the said recesses for engagement with the parallel undercut side walls thereof, and whereby the rib is fastened to the barrel so as to be free to have relative longitudinal movement with respect thereto due to expansion or contraction, while held against vertical or lateral movement, or displacement.
For rigidly connecting the rib and barrel at a point between the ends of the latter, I employ a locating-stud 12 and a fasteningscrew 13, the former passing upward through the rivet-hole 9 of one of the spacing-blocks 3 as shown in Figs. 7, 8 and 9, and securing this particular block to the lower face of the rib. This particular rivet, instead of having a beveled or undercut head like the other rivets, is formed with a cylindrical head 14 which enters a cylindrical hole 15 formed in the topof the gun barrel, as best shown in Fig. 9. The fastening-screw 13 passes downward through a hole 16 in the rib and through a hole 17 in the block into a threaded-hole 18 formed in the gun-barrel at a point directly in the rear of the hole 15 therein, as'shown in Fig. 11, the holes 15 and 18 just described, replacing one of the undercut keyhole recesses in the barrel. In mounting the rib upon the barrel, the beveled heads 7 of the dovetail rivets 6 are introduced intojthe rear ends of the heyhole recesses in the barrel, as already described. At this time the locating stud 12 will rest upon the barrel as shown in Figs. 2 and 9. Now as the rib is shoved forward to enter the heads of the rivets into the forward ends of the recesses, downward pressure is applied to the rib at the points aa thereupon, (Fig. 2) on opposite sides of the special spacingblock b, causing the rib to be bowed or buckled as at 0. As the rib moves forward under these conditions, the head 14: of the locating-stud 12 will ride upon the top of the barrel until it snaps into the locatinghole 15. The holes 16, 17 and 18 are now in registration and ready for the reception of 7 ends ofthe latter. 7
the fastening-screw 13 from which the stud 12 takes the shock of recoil. I claim 1. A single barrel firearm having its barrel formed in its upper face with aspa'ced series of undercut recesses, a sight-rib, a series of spacing-blocks fastened to the under face of the sight-rib by dovetail rivets coacting with the said recesses for connecting the rib and barrel for their relative longitudinal movement, and a locating-stud and a fastening-screw passing through one of the said spacing-blocks for rigidly connecting the rib and the barrel at a point betweenthe 2. A single barrel firearm having its 'arrel formed in its upper face with a spaced series of undercut keyhole recesses, a sightrib, a series of spacing-blocks fastened to the under face of the sight-rib by dovetail rivets for the relative longitudinal movement of the rib and barrel, and a locatingstud and a fastening-screw for rigidly securing the barrel and rib together at a point between the ends of the latter, the said stud fastening one of the said blocks to the said rib and formed at its lower end with a cylindrical head entering a cylindrical hole in the barrel and the said screw passing downward through the rib and the said spacingblock and entering a threaded hole located in the barrel at a point near the said cylin drical hole.
3. A single barrel firearm having a barrel, a sight-rib removably mounted thereupon, and means for rigidly connecting the sightrib and barrel at a point between the ends of the latter, the said means comprising a spacing-block, a locating-stud: fastening the of the said barrel and retained therein by the spring tension of the said rib.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses. 1
