LUMINOUS SIGHT FOR FIREARMS.

Specification of Letters Patent.

Patented J une 17, 1919.

' Application filed January 24, 1919. Serial No. 272,836.

To all whom it may concern:

Be it known that I, ERIK S. PALMER, a citizen of the United States, residing at New Haven, inthe county of New Haven and 5 State of Connecticut, have invented a new and useful Improvement in Luminous Sightsfor Firearms; and I do hereby declare the following, when taken in connection with the accompanying drawings and the charac-.

10 ters 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-- Figure 1 a perspective view of my im- 15 proved luminous rear sight.

Fig. 2 a broken view thereof in vertical section on the line 2+2 of Fig. 1.

Fig. 3 a perspective view of my improved luminous front sight.

Fig. 4 anenlarged view thereof, in central vertical section on the line 4-4 ofFig. 3. My-invention relates to improved luminous sights for firearms, whereby greater accuracy of aimed fire is secured in poor light or at night, the object being to produce at a low cost for manufacture, a simple, durable and reliable sight constructed with particular reference tofacility of adaptation to individual arms.

With these ends in view, my invention consists in front and rear sights formed with vertical slots or recesses for the reception'of the luminous composition and adapted at their upper ends to be filed off, if required, to adapt them to, the individual arms to which they may be applied. V Forthe illustration of my inventiongI have shown it as applied to rear and front sights of standard form. The standard rear sight; shown is made in one piece and come prises a relatively long spring base 5 provided under the under face of its forward end with a dovetail fastening-rib '6 and formed at its rear end withthe usual longitudinal slot 8 for the .reception of an elevator which is not shown. Atits extreme rear end -the base 5 has an upstanding sightleaf 9 having the. usual centrally located sight-notch 10. On the rear face of the leaf 9 and on either side of the sight-notch 10, I forma vertical slot orrecess 11' in each of i which I place a vertical strip 12 of a luminous composition which may be of any desired character, as for instance, the composition ,ity required.

sight-leaf 14 rises at a right angle to the may have the structure of the sights, but by their proamount of which may be introduced into these recesses to give the maximum luminos- In these recesses the radiolite is protected from abrasion or disruption, which is highly important. By virtue of locating the luminous composition in such vertical slots, I am enabled to initially construct the sight with a sight-leaf high enough for the minimum range. Now if on the trial of a given gun, after the rear sight has been applied to it, the gun shoots too high, it is an easy matter for the user to file down the top of the leaf until the sight has been in this way, perhaps by repeated filings, adapted to the individual gun. The point to be noted is, that the filing down of the fiat upper edge of the leaf 7 shortens the vertical slots 11 without changing their character. The filing down of the flat upper edge of the leaf 7 'afl'ects the proportionate removal of the luminous material 12 and the proportionate lowering of the sight notch 10 so that the upper edges of the luminous material, constituting the night-aiming points, and the sight-notch, constituting day-aiming point, are inoved'downward to the same extent -to adapt the sight to the individual gun. This result proceeds from the fact that the luminous material is located in vertical slots of uniform width.

The standard front sight herein shown, consists of a transverselyarranged dovetail- 'rib 13 or fastening-member from which the axis thereof, therearedge of this leaf being formed with a vertical slot or recess 15 for the'recept'ion and protection of a strip-like body 16 of radiolite or other luminous composition. The leaf 14 is initially made high enough to adapt it tohave its upper edge filed down to meet the shooting requirements .of the particular gunto which it may be applied. Here again the filing ofi of the top of the leaf in no wise changes, the jzharacter or operation of the sight but simply adapts 100 it to a given gun.

It is obvious that sights other than those of the particular forms shown and described,

my invention applied to them, my invention being 7 characterized not by-10l vision with'vertically arranged slots or recesses for the reception and protection of the luminous material and the adaptation of the parts in hich these slots or recesses are 11' to adapt the sights to 1. A gun-sight formed'with a vertical slotor recess for the reception and protection of luminous materialand adapted to have its I upper edge filed away with the'proportionate removal of the luminous material, whereby the night-aiming point is changed by the same amount as the day-aiming point to adapt the sight to the individual gun.

2. A gun-sight having a plurality of vertical slots or recesses for the reception and protection of luminous material and adapted to have the upper edgeiof the part'containing such slots or recesses filed away with the proportionate removal of the luminous material', whereby the night-aiming point is changed by the same amount as the dayaiming'point to adapt the sight to the individual gun. p

'3. rear sight for firearms the said sight having a base formed at its rear end with an upstanding sight-leaf the rear face of which is formed with two vertical slots located on opposite sides of the sight-notch, for the res to be file ception and protection ofv luminous material, the u per edge of the leaf being adapted away with the pro rtionate removal of the luminous materiafi whereby the night-aiming point is changed by the same amount as the day-aiming point to adapt the sight to the individual gun.

. 4. A front sight for firearms, consisting of a transverse fastening member and an up standing leaf located at a right angle thereto and having its rear edge formed with a vertical slot or recess for the reception and protection of luminous,material and having its upper edge adapted to be filed away with the proportionate'removal of the luminous material, whereby the night-aiming point is aiming point to adapt the sight to the 'individua gun. 4

In testimony whereof, I have signed this specification in the presence of two subscribchanged by the same amount as the day-
