(cite-1c) 8 Claims.

This invention is directed particularly to a combined rear sight. and cocking device for a breech block.

An object of the invention resides in the provision of such a device that is so constructed and related to the breech block and stock extension that the breech block may be manually drawn to a cocked position thereby and will automatically return the device to its normal position upon the first movement of the breech block to its breech closing position.

A further object of the invention resides in so correlating the parts that the sight will'be unaffected by the subsequent movements of the breech block to either breech closing or breech opening positions.

Another object of the invention resides in so constructing and mounting the device that its accidental movement from normal position will be prevented. It is also an object of this invention to provide a device of the character referred to that may be incorporated either in new or already constructed guns.

A still further object of the invention is to so T construct the device that the opening through the stock extension or receiver through which the connection to the breech block extends will be sealed at all times when the device is in its normal position.

With the above and other objects in view the invention consists of the combination and arrangement of parts set forth in the appended claims, but it is to be understood that certain changes may be made within the scope of the claims without departing from the terms or spirit thereof.

In the drawing:

7 Figure 1 is an elevation of a gun of the type wherein a reciprocable breech block is forced to its retracted cr breech opening position during automatic action by the recoil of the gun, and is forced to its breech closing position by a mechanical means such as a spring;

Figure 2 is a fragmentary plan View of the cocking means;

t Figure 3 is a section on line 3-3 of Figure 2,

but partly broken away;

Figure 4 is a section on line 4-4 of Figure 3; and

Figure 5 is a section on line 55 of Figure 3.

The gun that I have illustrated in the drawing to show the applicability of the invention includes a barrel l, cooling fins 2, a forward sight 3, a compensator 4, a shoulder or butt stock 5 having a forward extension or receiver 6, a. front stock 1 and a pistol grip 8.

In the form of gun that is here illustrated the breech block 9 is slidably mounted in the stock extension 6, which acts as a receiver, and is provided with a forward extension [0 that is slidable within a recess in the front stock 1. A rod l I is secured in a forward projection of the stock extension 6 or receiver at l2 and projects forwardly where it is provided with a head I3 adapted to abut against a shoulder or a recess in the breech block extension In. A spring l4 surrounds the rod H abutting at its forward end against the shoulder I5 in the extension [0 of the breech block, and at its rearward end against a washer l5 between which and the projection of the breech block a shock absorber 11, preferably of rubber, is interposed.

This arrangement of breech block and its actuating mechanism is similar to that disclosed in my co-pending application 338,890, filed June 5, 1940. The spring [4 operates to move the breech block into its breech closing position after it has been forced into its retracted position by the action of the chamber pressure after firing.

The gun may be provided with an action mechanism at l8 of any desired form, and this, too, may be of the form disclosed in said co-pending application.

The combined rear-sight and cocking device includes a body portion l9 that is provided with a cylindrical sight opening 29, the forward face 2| of said body portion being curved. An extension 22 projects forwardly from the body portion and an extension 23 rearwardly therefrom.

The body portion l9 and the

extensions

22 and 23 are provided with a dovetailed groove 24 in their lower faces which coacts with a track 25 of complemental configuration to permit the body portion and extensions to slide upon the rear stock extension 6 and to'keep the sight opening 253 in proper alignment. This track 25 may be secured to the extension 6 0n the receiver by any suitable means as, for instance, by such means as screws 21, which are illustrated.

In order that the breech block may be retracted for initial cocking against the action of the spring I4, I have provided the forward end of the extension 22 with a finger 28 which slidably engages in a notch 29 in the forward upper end of the breech block 9, which notch 29 is open at its forward or breech end.

Thus when the curved surface 2| of the body portion 19 is engaged by the finger of the operator, or when the body portion is otherwise engaged and drawn rearwardly against the action of the spring I4, the combined sight and cocking device will move rearwardly until the finger 22 engages the rear end of the slot 29. Further movement will draw the breech block 9 rearwardly against the action of the spring l4 until the breech block reaches its cocking position and is engaged by the detent mechanism to which I have already re- '1 ferred, the finger 28 sliding in the slot 28' which is formed in the rear stock or shoulder extension 6 or in the receiver. i

When the gun is fired 'by the pulling of the trigger and the' breech block 9 moved forwardly under the action of the spring 14 that hasbeen compressed during the rearward movement of the breech block, the breech block will carry the sight and cooking device forwardly because of the engagement of the finger 28 in the slot 29. How- 'provided a'ilatch 3B which is' pivoted at 31 on the bodyportion It. This latch carries a pawl 32 that is adapted to engage in a notch 33 in the track 25 and that is normally urged. into engaging position by aspring 34 whose tension may be adjusted by a set screw 35. g

"This latch is also provided at the opposite end with aknurled finger piece 36, pressure on which will oscillate the latch about its pivot 3| and disengage the pawl 32 from the notch 33 against "th tensionof the. spring. 'This'disengaging movement'of the pawl is limited'by the engagement of a projection 31 on the latch, which projection is adapted to engage the upper face of the track25, as indicated in Figure of the drawing.

It' will be noted that the combined rear sight and cocking device is adapted for application to new or already constructed guns, for the breech block, the receiver or the rear or shoulder stock extension may be recessed to receive the finger 28 and the track '25 may be secured to the rear stock extension or'receiver without materialalteration of the latter. a

Moreover it is to be noted that the device will be heldsecurely in position during the automatic reciprocation of the breech block, so that there wil1 be no'disturbance of the alignment of the rear sight with the forward sight.

It is also to be noted that the slot 28, through What I claim is:

1. In a gun, areceiver having a slot extending longitudinally thereof 'inits upper wall; are
