RIFLE ATTACHMENT 2 Sheets-Sheet 2 Filed May 19, 1933 |NvENToR` ATTOR N EY Patented Oct. 29, 1935 UNITED vSTATES PATENT OFFICE 1 Claim.

This invention relates torearms and has for the primary object, the provision of an attachment adapted for any type of shotgun to provide in combination with the latter arifle so that a 5 hunter may have in a single unit both a shotgun and a rifle, placing the hunter to ybetter advantage when hunting due to the fact that either the shotgun or the rifle may be used to meet varying hunting conditions as they Varise and l the attachment is of such a construction that it will not interfere with the use of the shotgun and may be readily detached therefrom when desired.

With these and other objects in kView this inlti vention consists in certain novel features of construction, combination and arrangement of parts to lbe hereinafter more fully described and claimed. Y

For a complete understanding of my inven- 20. tion, reference is to be had to the following description and accompanying drawings, in whichA Figure 1 isa side elevation illustrating a shotgun with my invention applied thereto.

Figure 16 is a fragmentary plan View illustrating the same. Y

Referring in detail to the drawings, the numeral I indicates a conventional type of shotgun to which my invention is applied and includes 1o the shoulder stock 2, breech 3 and barrels 4, the latter being connected to the breech 3 by a forestock 5 similar in construction to the conventional type of forestock now employed on shotguns except that it is adapted to receive and support the attachment for the shotgun so that the gunner may have a rifle in combination with the shotgun.

A rifle barrel 6 of any desired caliber is supported near the rear end of the barrel 4 within a 20 chamber 'I formed in theforestock 5. The barrel 6 has an extension 5I) which abuts the lug 5I securing the forestock to the gun, thus, pro.- viding resistance to the impactof firing. The rifle barrel extends parallel and in a plane below the barrels of the shotgun and has its forward end fitted in a clamp 8 which forms part of a bracket secured to the barrels of the shotgun by screws 9 passing through slots 9'. The slots pro,- Vide for range adjustment horizontally while the thickness of theV hanger cares for perpendicular range adjustment. l

The rifie barrel 6, forwardly of the forestock,

Vis provided with a firing chamber ID and, ad.-

jacent said chamber, is provided with an ammunition slot II to permit ammunition to be placed in the chamber III and extracted therefrom, the shell being discharged exteriorly of the barrel by a. bolt type ejector which will be hereinafter more fully described. A bolt I2 is slid- 40 ably mounted in the rie barrel in rear of the firing chamber and is of cylindrical formation to slidably support a iiring pin I3. A pin I4 slidably connects the boltwiththe firing pin so that they may have a limited vsliding movement relative to each other. The firing pin is'of hollow formation with one end closed by an integral wall carrying a pointed projection I5 to impinge upon and explode the `cap of theammunition in the ring chamber, a coil spring Il being interposed A between the end wall of the firing pin and the pin I4 for normally urging the firing pin towards the firing chamber. It must be understood that the pointed projection I5 may be arranged for rim firing although it is shown arranged for center ring. A finger piece I9 is fixed to the bolt I2 and extends through a slot 20 in one side of the barrel 6, said slot having lateral branches 2| to be occupied by the nger piece I9 when the bolt is to be held against endwise movement. A set bolt 22 is secured to the bolt I2 and operates ina slot 23 in the barrel and also extends into the chamber of the forestock. The ring pin is provided with a slot 24 aligning with the slot 23 in the barrel and a corresponding slot in the bolt I2 to be engaged by a sear 25 for the purpose of holding the firing pin in a cocked or firing position. The sear is pivotally mountedgas that the device or attachment may be easily and shown at 26, within the chamber ofthe Vforestock and is engaged by a spring 2-'I to normally urge the head 28 of the sear through theV slot 23 into engagement with the'slot 24 of the ring pin when moved into iiring position Y through the manipulation of the bolt. ,-Therear end of the sear engages a plunger type trigger '28' mounted in a cup 29 carried by a closure plate 30 located on the opposite side of the forestock from the finger piece I9 of the bolt. The trigger is spring pressed by a spring 3l to retain the trigger in operative position.

The forward end of the bolt carries spring pressed and pivotally mounted ejectors 32 to engage the rim of the shell when in the ring chamber so as to extract it on the rearward movement of the bolt and discharge it through the slot I I.

A safety catch 33 is slidably mounted on the closure plate 3E) to engage a shoulder 34 of the head 28 of the sear for locking the same against pivotal movement and release of the ring pin from firing position. A finger piece 35 is connected to the safety catch and located on the closure plate adjacent the trigger so that the person using the iirearm can readily lock or unlock the sear. y

In operation, the rifle is loaded by moving the bolt rearwardly, thereby uncovering the ammunition slot I I so that a projectile may be inserted into the firing chamber. The bolt is then moved forwardly to bring the forward end thereof in engagement with the cap end of the projectile. The bolt when moved rearwardly to permit the loading of the rie carries with the same the firing pin which is automatically engaged and held in a rearward position by the sear, thereby placing the rifle in firing position when the bolt is returned forward for holding the projectile in the ring chamber. During the use of the gun when loaded, the safety catch is in engagement'with the shoulder of the sear until it is desired to fire the rifle when the safety catch is released from the sear. When the bolt is moved rearwardly, the set screw 22 is carried against the safety catch which is thereby moved into engagement with the sear, as shown in Figure 3. When the bolt is moved forwardly, the catch will remain in engagement with the Sear, and it will not be released until the nger piece 35is manipulated. To fire 5 the rifle the trigger 28 is depressed, rocking the sear on its pivot and disengaging the head thereof from the ring pin, allowing the latter to travel forwardly under the influence of the spring I'I and carry the pointed element, I5 into `engage- 1o ment with the cap of the ammunition with force sufficient to cause an explosion. Y

From the foregoing description it will be seen quickly applied to a shotgun and removed there- 15 from when desired. The removal will necessitate the Aremovingv 'of the rifle barrel from the forward hanger and the disconnection' of the forestock from the breech. An ordinary forestock may be substituted in lieu of the removed forestock at- 20 tachment when desiring to use the'shotgun inthe ordinary manner. 'Ihe shotgun v'when Vequipped with the rie attachment gives the user the advantage ofV a shotgun-combined with a rie so as to meet all occasions of hunting that may arise 25 as sometimes it Yis more advantageous to employ a rie for killing the game than a shotgun. The device is to be Vconstructed as lightly as-possible with the assurance of safety so as not to materially increase the Weight of the shotgun. 30

While I have shown and described the preferred embodiment of my invention. it will `be understood that minor changes in construction, combination and arrangement of. parts may be` made without departing from the spirit 'and scope of 35 my invention, as claimed. 1

Having described the invention, I claim? A gun attachment comprising a forestock hav.- ing a vchamber and slots communicative with the chamber and opening outwardly through opposite o Walls of said forestock, a plate secured to the forestocktorclose one of the slots, a barrel extension mounted in the chamber and having slots aligning with the first-named slots, Va barrel integral with the extension and having a' firing 5 chamber communicative with the extension, a breech block slidable in the extension, ajnger piece carried by the breech blockA and extending through one of the slots of the forestock byway of one of the slots of said extension, a ring means 5c,` slidable in said breech blockya sear for holding the ring means in cocked position and pivotallymounted to said extension and arranged inthe slot of the forestock closed by said plate, aslidable button typetrigger carried .by said plate and 55 engageable with the sear, and a safety catch for the sear and carried by the plate. f
