Description
ocr. 12., 1925. 1,557,435
L. N. DlEly-IM FIREARM Filed Feb, 24, 1925 raf/vir also moved out of the path of movement of said shoulder. This releases the spring support 17 from the retainer and said support is forced by theV spring backwardly against the bottom of the recess 18. The breechbolt may now be slid along its ways and removed from the rear end of the frame. `When it is desired to replace the' breechbolt the lever 30 is again moved downwardly, as above described and with the same results, and the breech-boltmay be readily slid to place. In this movement. of the breech-bolt should the retainer 28 be located in its path of movement the rounded or beveled rear end of the retainer, as shown j in Figures 2 and -4, will cause the breechbolt stop to be pressed downwardly so that the retainer will not prove an obstruction to Vthe movement of the breech-bolt. 1When the breech-bolt has been seated the push lug.
r 18 is pressed inwardly to register the opening 29 with theV retainer 28 when the latter will spring into place in said opening and the support 17 will thus be held to effect contract-ion of the spring when the breechbolt shall be moved backwardly.
In order that the hammer 26 shall not obstruct the replacing of the breech-bolt I so construct the pivotal point 35 of attach-- ment of the hammer plunger 86 and the nose 37 of the hammer, that when the latter is pressed downwardly by the shoulder 34C in the backward movement of the breech-bolt the pivotal point of attachment of the plunger to `the hammer will be moved past a straight line extending between the pivot of the hammer and the point of rest of the plunger upon the hammer actuating spring 38 and to the position shown in dotted lines in Figure 2 of the drawings. lIhe result of this positioning of the parts'will be that the spring 38 will hold the hammer in its retracted position and the nose 87 will, therefore, be located out of the path of movement of the breech-bolt in the ope-ration of replacing said bolt upon the receiver. The
pivot 35 is so located that it will not pass to a great distance beyond a straight line between the pivot of the hammer and the iesting point of the plunger so that the slight jar incident to forcing the breech-bolt to place, asfby striking the rear end with the hand, will dislodge the hammer and cause it to move into position where it is held in the usual manner by a sear 39, and this same operation will take place when the breechbolt is moved backwardly by the forces of discharge.
In accordance with the provisions of the patent statutes I have described the principles of operation of my invention together with the device which I now consider to represent the best embodiment thereof; but
`I desire to have it understood that the device shown is only illustrative, and that the invention may be carried out by other means and applied to uses other than those above set out. t
I claim 1. A firearm including a frame, a breechbolt slidably attached to the frame, a hammer pivotally mounted on the frame for engagement by the breech-bolt, a spring having a pivotal point of connection with said hammer for actuation thereof, said pivotal point being positioned to force the hammer backwardly when said hammer is in its rearmost position, means for positioning the hammer in such a sensitive but inoperative retracted position as to effect movement from such position by the j ar incident to the manual closing of the breechbolt to an operative ring position, means for holding the hammer in such firing position against thecforce of said spring, and means for releasing said holding means.
Q.. A firearm including a frame, a breechbolt slidably attached to the frame, a hammer pivotally mounted on the frame for engagement by the breech-bolt, a. spring having a pivotal connection with said hammer for actuation thereof, the engaging parts of said breech-bolt and hammer being formed to cause said pivotal point of connection to pass to a point to force the hammer backwardly when said hammer is in its rearmost position, means for positioning the hammer in such sensitive but inoperative retracted position as to` effect movement from such position by the jar incident to the manual closing of the breech-bolt to an operative and liring position, means for holding the hammer in such `firing position against the force of said spring, and means for releasing the hammer.
3. A firearm including a frame with a recess therein, a breech-.bolt slidably attached to the frame overlying said recess, a breech-bolt stop movably located and having a restricted movement in said recess to limit backward movement of the breechbolt, means for moving said stop in said recess, a breech-b-olt retracting spring located Vin the breech-bolt, and means on said stop to act as a seat for said spring.
