d.4. & 4.5. Bolte Postale Browning We 19h9 express today Company 22 Herstal~Leg—Liege, Dear June 29, Belcium Delvauwx: are sending to you by air one 20 gauge Super receiver with all normal parts mounted thereon and one supplementary part, purpose of which I shall now deseribe. the One of the principal defects ef the 20 gauge guns so far has been the failure for the trigger mechanism to shift after firing of the first shot. This is due in large part to the excessive strength of the con~nector piston spring, but if we decrease the strength of this spring, as we have done aid are doing temporarily, we decrease the tendency of the trigger to return to unfired position, Therefore I have added a supplementary flat spring which is mounted on the lower tang and which bears on the rear of the trigger to urge this can be seen from the model. There are, however, point out now. Same as the width the latter downwardly, some changes in the model which I should The width of the flat rear of the mounted on model, and I should tang. lower The at the should be slightly .2 mm in thickness. like should tang at the point where the spring say about spring as the spring is than the forward end thinner At the to be of the model spring is a slight depression which is entirely accidental =. the Spring should be made as shown in the simtch enclosed herewith. The binding pest should have about .2@ ma milled or filed away at the point indieated by the letter "A" in my sketch to make room for the folded rear end of the spring. The point "B" of the binding post snould net be forced against the top of the spring when the lower binding post screw be any looseness is tightened. On the other Now in addition a new connector piston spring piano Wire having a slightly smaller diameter but with about 13 to 15 coils so that when mounted in the gun will be equal present spring; that guns type hand, there should not at this point. and rediced in length is, the the spring for 20 gauge should be made of a than the present spring strength about as of such 7 or 8 coils now mounted cuns. in new spring of the 12 gauge
