9 Claims.

This invention is a small-bore target rifle which is especially designed to meet the conditions of American matches in the most satisfactory way.

It is described in the following specification and illustrated in the drawings, in which- Figure l is an elevation of the rifle; and Fig. 2 is a longitudinal section through the lock mechanism.

Referring to the drawings, I l is a barrel having 1 a chamber l2 to receive a .22 calibre long rifle cartridge. Inasmuch as many of the most important American matches are any sigh matches, the piece will frequently be equipped with a conventional telescopic sight (not shown),

15 the line of sight being located as usual about 1.5" above bore center. For metallic sight matches the sights will be located at the same level so that the rifiemens shooting position can be the same in both types of matches.

[3 is the comb of the stock which is shown substantially in line with the bore so as to give a drop of about 1.5" from the normal line of sight. For greatest steadiness in prone position, the drop should be 1 to 1%". The comb may properly be located a little lower than is illustrated in order to permit a straight cleaning rod to clear the comb.

The point of the comb is located as near the look as is compatible with a comfortable grip [4 of approved form. I5 is the trigger which is located at an acceptable distance from the grip, about 3.5" from the forwardedge of the grip when the grip is curved as illustrated. This brings the trigger about 4" longitudinally in front of the point of the comb. The butt I6 is located atthe proper distance from the point of the comb for the comb to support the face in prone position. This requires for a rather tall man a length from butt to point of comb of about 10.5" and from butt to trigger of about 14.5. In this type of prone stock, the length of comb measured from the butt to the point of the comb is normally approximately 70% or more of the butt length measured from butt plate to trigger.

The lock action is illustrated only in section, its parts being largely similar to the corresponding parts of the Winchester model 52 target rifle. The significant mechanical modifications are described.

- The bolt assembly, including bolt l1, striker I8, bolt handle sleeve I!) with cooking cams 20 and the cocking piece 2| with cams 22, is made very short so that it can be removed to the rear despite the very high comb. The total length of the bolt 55 assembly must not exceed the distance from the point of the comb to the rear of the receiver bridge 23. To render so short a bolt practical, it is extended behind the bolt sleeve to receive a main spring abutment pin 24, and the cocking piece cams 22 are elongated to reach around this 5 bolt extension and engage the bolt sleeve cams 20. The receiver 25 is made short to correspond with the bolt, the shortening as compared with conventional locks occurring in the bridge 23. The magazine well 26 is conventional and is adapted to receive a conventional long rifle cartridge magazine. The trigger l5, being located as above described, falls directly behind the magazine well and may conventionally be pivotally mounted thereon as illustrated. The sear 21 is provided with a tip 28 beveled on the rear to engage a corresponding face 29 on the striker and square on the front to engage the rear face 30 on the loading lug 3| of the bolt which, by engagement with the sear, serves as a bolt stop.

The sear is pivoted to the rear of the receiver and extends forwardly from its pivot, its upwardly extending lug 28 being positioned in the path of the striker just behind the magazine well. The trigger l5 has a tip 32 which engages the sear to support it. The depth of trigger engagement is adjusted by a screw 33 in the sear. The sear is of the type which yields under pressure, except when supported by the trigger. Hence, by adopting a proper bevel on the sear and striker, the pressure on the engaging surfaces of the sear and trigger may be reduced as desired.

To remove the bolt, the piece is snapped so that the striker depresses the sear below the line of the loading lug. The trigger is then firmly pressed back to engage a screw 34 on a downwardly extending lug 35 on the sear. The sear is thus held down by friction and the loading lug on the bolt will clear. To replace the bolt, the sear is depressed, with a tool or stick, and held down by back pressure on the trigger. Or the upward play of the sear may be so limited that the front of the bolt will strike the bevel of the sear and ride over it. Back lash of the trigger may be practically eliminated by adjusting the screw 34. The trigger surface which engages the screw 34 is preferably cut on an arc concentric with the sear pivot so that any movement of the sear which may occur after the trigger is squeezed off will not disturb the trigger. This surface of the trigger may, however, be so cut that the rise of the sear requires a slight forward motion of trigger. The present arm combines the advantages of the bolt action in excellent handling of cartridges in loading and of shells in extraction, the convenience and general utility of the repeating mechanism and a stockwell fitted for prone shooting with aconventional telescopic sight while preserving convenience of assembly and attaining easysingle' shotloading with the butt on the shoulder. .The foregoing desirable operative fea- A tures have heretofore been quite incompatible;

'If the comb is tosupport the face as it should and if the grip is to be of conventional form in front of the comb, the chamber must be very close herein, and in thefollowing claims, I mean a rifle f substantially asdefinedin the rules of the National Rifle Association of America, i. e., one handling 1 1a small-bore cartridge which in turnis defined as a rim fire cartridge containing a lead or lead alloy bullet weighing not over fortygrains and notover .223 in diameter, the cartridge having. an overall length not exceedingll' Unless the'rules which are of very'long standing should be. materially changed, the pr'esent invention can'be usefully embodidin'n'o'other'type of weapon. The important operative feature of the cartridge cooperating with the present rifle is its overall length and I intend to include within my invention rifles whose normalbolt throw in loading and ejecting is not substantially greater than that necessitated by la cartridge of. this length.

What I claim as new, and desire to secure by Letters Patent, is:

A' bolt actionrepeating small-bore target 'rifle having a stock with a comb of a length to sup- 'port'the face in'conven'tional prone position, the

point of thecomb being higher than the lower line of the bolt and having its receiver bolt assembly and comb co-ordinated to permit rearward removal of the bolt-assembly in the space in front of the point of the comb.

2. A rifle according to claim 1, having a trigger located substantially closer to the chamber than to the point of the comb.

3. A bolt action repeating small-bore target rifle having a stock with a comb, the point of the comb being higher than the lower line of the bolt and the length of the comb being approximately 70% or more of the butt length, the receiver and bolt assembly being so co-ordinated to the comb that the bolt assembly is removable rearv/ardly in the space longitudinally ahead of the point of the comb.

4. A rifle according to claim 3, in which the longitudinal distance from trigger to chamber is less than the longitudinal distance from the point of the comb to the trigger.

5. A repeating small-bore rifle of the bolt action type including a chambered barrel, a bolt assembly with striker, a receiver having a portion overhanging the bolt to guide the same, a magazine well, a sear, a trigger, and. a stock with butt, comb and grip, the point of the comb of the stock being higher than the lower line of the bolt assembly and the length of the comb being approximately 70% or more of the butt length, the bolt assembly being not materially longer than the space between the point of the comb and the bolt-overhanging part of the receiver, whereby the bolt can be removed rearwardly without interference by the comb.

6. A repeating rifle of the bolt action type including a chambered barrel, a bolt assembly with striker, a receiver having a portion overhanging the bolt to guide the same, a magazine well, a sear, a trigger, and a stock with butt, comb and grip, the point of the comb of the stock being higher than the lower line of the bolt assembly and the length of the comb being approximately 70% or more of the butt length, the bolt assembly being not materially longer than the space between the point of the comb and the bolt-overhanging part of the receiver, whereby the bolt can be removed rearwardly without interference by the comb, and the trigger being directly behind the magazine well, the longitudinal distance from the point of the comb to the trigger being in the order of of the longitudinal distance from the point of the comb to the chamber.

7.. The rifle of claim 6, in which the trigger pivot is supported by the magazine well.
