Description
i.
~(34~ 33 The invention relates to a mounting for a telescopic sight such as is used on a rifle, and in particular to mountings which may be fitted on several rifles, thereby permitting a single telescopic sight ~o be transferred from one rifle to another.
BACKGROUND OF THE INVENTION
Telescopic sights are usually attached on rifles by means of drilling holes, and tapping threads, and some form of mounting or shoe is then attached on the rifle by means of screws or bolts.
The telescopic sight is then usually attached to such a shoe. Gen-erally speaking, only one such mounting is provided for each tele-scopic sight, although in most cases, the telescopic sight may be removed fro~ the mounting for safety during handling or storage, and will be attached on the mou~ting only wher. the rifle is prepare~
for use.
Generally speaXing, such sight mounts as those described, wexe not suitable for multiple use to permit a sight to be moved from one rifle to another. The drilling and tapping of holes in the rifle mechanism made it possihle for minor errors to be made in the attachment of the mount to the rifle. Normally, where only a single rifle is used with a particular sight, then during shoot-ing in at a target, the sight will be adjusted to eliminate any ' such errorsO
However, if two or more such mounts are attached to two or more different rifles, then the errors in mounting will be dif-ferent. As a result, when changing one such sight fro~ one riflè
to another it will have to be zeroed on the range before it ~an be used.
As a result, it is generally speaking the practice to provide a separate mount and a separate sight for each rifle.
This of course is relatively expensive and wasteful. The .
~,,,' , -1-- ~
,, I
,, , ;~ invention therefore seeks to permit a sight to be used interchanqe-ably between several rifles, by providing a universal standardized mount, for a given type of rifle.
~.
The invention seeks to overcome the foregoing disadvantages by the provision of a mou,nting shoe or a telescopic sight, adapted ~ for attachment to a rifle of the pattern having two spaced apart sup-,` porting structures adjacent the breech mechanism of the rifle, and the mounting shoe being provided with two spaced apart attachment members for attachment to such support members, and including fast-`10 ening means for fastening said attachment members to said support members without drilling, tapping or machining.
More particularly, the invention seeks to provide a sight mounting shoe having the foregoing advantages in which the rifle has a rear supporting member comprising two spaced apart up wardly extending flanges, and holes drilled in said flanges in registration with one another for rsception of a locking pin there-through, and further having a front supporting member having two spaced apart upwardly extending flanges, and a cross-bar extending therebetween, and wherein the sight mounting shoe is provided with ~;20 two spaced apart front and rear block members adapted to fit between ; said front and rear attaahment-members on said rifle. ^ ~
More particularly, it is an objective of the invention to provide a sight mounting shoe having the foregoing advantages in which the rear block member is provided with a transverse drilling adapted to register with said holes in said flanges in said rear, support member, and wherein said front block member is provided with a longitudinal threaded hore and set screw therein, adapted to engage f said transverse bar member of said front spacer member, thereby locking the sight mounting shoe in position on ~e ri~le.
lt is a further and related objective of the invention to provide a sight mounting shoe having the foregoing advantages which incorporates an upwardly displaced longitudinally extending slide member, adapted to receive front and rear sight clamps attached to the telescopic sight, whereby the telescopic sight may be slid on and off the slide member, and whereby it may also be located in different longitudinàl positions to accomodate different eye posi-tions for the user.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed ` 10 to and forming a part of this disclosure. For a better understand-ing of the invention, its operating advantages and specific objects ; attained by its use, reference should be had to the accompanying ~i drawlngs and descriptive matter in which there are illustrated and ~; described preferred embodiments of the invention. 3 IN THE DRAWINGS :- i -Figure 1 is a side elevational view showing a portion of a rifle~ with a telescoplc sight mounted thereon, on the mount-ing shoe according to the invention;

~: DESCRIPTION OF A SPECIFIC EMBODIMENT
Referring now to Figure 1, it will be seen that the breech portion of a typical World War II service rifle is shown, in this case a Lae Enfield No. 4. Service weapons such as these have achieved wide distribution amongst hunters and rifle enthus-iasts, who frequently own two or more such weapons of the same - - ... .. ..... ..
`
~ pattern.
,~; As shown in Figuxe 1, the rifle illustrated has a stock 10, a breech 12, a trigger 14, a magazine 16, a bolt 18 having a bolt head 20. All of these components of a ri1e are well known and require no further description.
~ As a portion of the general breech assembly 12 the rifle ',~ is provided with a pair of spaced apart flanges 22 standihg upwardly on either side of such breech assembly. As manufactured, such j~ ^ flanges 22 provided a mounting for a rear sight for the rifle. As ,~10 such, the flanges 22 were provided with holes 24 extending there-through in registration with one another for reception of a sight ~ mounting pin ~not shown).
`~ The breech mechanism 12 is further provided with a further pair of flanges 26 standing upwardly on either side thereof, and between which a transverse bridge member 28 is provided. The bridge member 28 provides additional strength for the breech 12, and also, together with the flanges 26, provides a support for an ammunition clip by means of which the magazine 16 may rapidly be loaded, in ~'i the conventional rifle~ ¦
According to the present invention, the sight mounting ~ ; shoe takes ad~antage of these two features of this particular ',~ pattern of rifle, for the attachmen,t of the mounting shoe in a '~
predetermined position, without the need for machining, tapping, or drilling.
It will of course be appreciated however that while the ~ invention is described in connection with a Lee Enfield No. 4 ,~, rifle, the invention is equally well applicable to other forms of "~ rifles havlng standardiz~d breech portions to which a mounting shoe accor~ing to the invention may be attached. Thus for example ' 30 many serviçe rifles from different countries incorporate essen-- 4 _ tially similar features such as rear sight mounts, and transverse ` bracing members, to which a mounting shoe, with minor modifications may be attached.
The invention is not therefore intended to be limited specifically to the Lee Enfield No. 4 pattern of rifle, but is intended to be of general application, with minor modifications to ~;; suit the particular pattern of rifle.
Referring now to Figures 3 and 4, the mounting shoe is i; shown generally as 30, a~d will be seen to comprise an upper slide ~10 portion 32, and a lower mounting portion 34. The slide portion 32 ''! ` i~ connected to the mounting portion 34 by means of a central elong-; ated rib portion 36.
The slide portion 32 is provided with angled edge forma-~ tions 38 along either side thereof for reception of suitable clamp-i`;~ ing devices on a telescopic sight. Such a telescopic sight T is shown in Figure l,having typical clamping devices C. Such clamping ~`~ devices C will have means (not shown) for receiving the edge forma-ions 38 of the slide 32, and may be 1:ightened up on it by means such as the~nuts N.
20~ ; It will of course be appreciated tbat the shaping of the slide ~32 and the edge formations 38 will be dependant upon the characteristics of the clamping devices C of the particular tele-scopic sight T. Thus where the clamping device C is provided with different clamping formations (not shown) then the shaping of the edge formations 38 and the slide 32 will be different.
The slide portion 32 is of sufficient length that it extends a greater distance than the spacing between the two clamps C on the sight T. In this way, it is pofi~i~le for the sight T to be positioned either further forward or further back depending upon the head position o thelowner of the rifle.
' ~ 4~z~3 The mounting portion 34 i~ provided at its rearward end with a rear block portion 40 having a predetermined width making a tight fit between the rear flanges 22 of the breech 12. It is also provided with a central hole 42 registering with the holes 24 in the flanges 22, through which a fastening pin or screw such as the ~ pin 43 may be fastened. , ; At the forward end of the mounting portion 34 a forward mounting block 44 is provided. Block 44 has a width dimension adapted to make a tight fit between the flanges 26 on the breach 12. A groove 46 is provided in the block 44 for reception of the transverse cross-bar 28, and the rearward block portion 44a is adapted to fit behind the bar 28, again fitting tightly between the flanges 26.
A longitudinal threaded bore 48 extends axially relative ~ to the mounting shoe 30 along the center of the mounting block 44 ;~; as shown, and a suitable set screw ~not shown) is adapted to be received in the threaded bore, and may be operated by means such as an allan key or other suitable device. I~ can be tightened down against the cross bar 28. In the particular pattern of rifle shown namely the Lee Enfield No 4, the cross-bar 28 has a slight undercut on it, and the tightening of the set screw in ~he threaded bore 48 will have the effect of continually tightening downwardly, thereby resisting any tendency for the mounting shoe 30 to jump ~ upwardly as the rifle is~fired.
!~ ~ In order to accommodate movement of the bolt 18, the mounting portion 34 is preferably provided with a longitudin~l shallow groove 50. In order to facilitate insertion of ammunition into the breech 12, the rib 36 may be cut-away as a~ 52. In ; operation, it will of co~rse be appreciated that the sight mounting shoe may readily be attached to the rifle without ~' ' .
" ~.
~ ' ~
machining.
All that is required, assuming the rifle is in its original condi ion, is to xemove the rear sight (not shown) which '~ is normally some form of simple peep sight located between the flanges 22, and retained by a bolt (not shown). All that is required is simply to remov~ the bolt at the sight.
~:; No preparation will be necessary at the flanges 26 and .
cross-bar 28. 1 .
, The rear block portion 40 is then pressed between the .
flanges 22,~and the forward block 44 is pressed between the flanges ~6. Generally speakingj the m~nufactura of the mounting shoe will be such to insure that these two members make a good :: pressed fit, but do not re~uire the use of any special machines.
. The pin 43 is then inserted through the hole 24, and then through the hole 42 in the block 40 and then through the ~' hole 24 in the opposite flange 22 and i~ then fastened by any `~ suitable means such as a lock nut tnot shown) or the like. I
The set screw (not shown) in the threaded bore 48 is .
hen tightened up by means of a key. The.telescopic sight : : :
~: 20~ may then be attached on the slide portion 32 at a suitable location ~ or the owner of that rifle and the rifle and sight are then ready ,~ fox use.
~ The attachment of the sight to the slide will be :'~ accomplished by simply tightening up any suitable clamping device ,~ C which is provided on that particular form of telescopic sight., Clearly, the telescopic sight may be moved from one rifle ;: to,another readily without disturbing the mounting shoe itself, : since similar mounting shoes will be provided on other such rifles so that the one telescopic sight may be used on one ri~le after another~
~L~41Z5~
It will of course be appreciated that the same mounting shoe may also be used for mounting a peep sight on the rifle, so that the same rifle may be used for example with a telescopic sight for hunting, and with a peep sight for competitive target shooting, where telescopic sights are not permitted.
To give the entire device still further flexibility, one or more index markers 54 may be provided on the rear end of the slide portion 32. Such indicators or markings will preferably be inscribed in the metal, and will be prominently coloured. In this wa~, the mounting shoe itself will provide a somewhat crude ~ form of open sight if it should be necessary to use the rifle for ;~ hunting, where the telescopic sight is either unsuitable or is ~, not available.
~, llaving described what is believed to be the best mode by which the invention may be perforrned, it will be seen that the invention may be particularly defined as follows:
l ~
A gun sight mounting device for use in combination with , .
a rifle of the type having a breech mechanism incorporating front ~;` and rear spaced apart upwardly extending mounting members thereon, and hole means in at least one of said mounting members, said front and rear mounting members each being of a predetermined width, said mounting device comprising a mounting body member adapted to extend at least between said front and rear mounting members, an upwardly extending mounting slide member connected to said body member, and adapted to receive said gun sight thereon, front and rear connection members extending downwardly from said mounting body, and spaced apart a predetermined distance corres-ponding to the spacing between said front and rear mounting mounting members on said breech of said rifle, and having wedging surfaces thereon adapted to inter-engage tightly with said mounting means, and fastening means in said connection members adap~d to register with said hole mean~ in said at least one of ~ai~
mounting members, and being inter-engageable therwith, whereby said connection members may be fastened in position in engagement with said mounting members.
The foregoing is a description of a preferred embodiment of the invention which is given here by way of example only. The invention is not to be taken as limited to any of the specific features as described, but comprehends all such variations thereof as come within the scope of the appended claims.
