DELAYED-ACTION DEVICE FOR IMPACT-FUSES.
Application filed. December 31. 1912.
Specification of Letters Patent.
Patented Nov. 25,1913.
Serial No. 739.562.
The object of the invention is the construction of such fuses wherein any undesirable retardation of the ignition is avoided when the delayed-action device is disconnected.
One embodiment of the invention is illustrated in the drawing showing a combination fuse provided with double ignition, wherein the turn-cock is also constructed to connect the time fuse. which is provided with a time train. either with the shrapnel bursting charge or the shell bursting charge.
Figure 1 shows a longitudinal section through the'axis of the fuse; Fig. an elevation partly in section along line '2 2 of Fig. l and seen from the left with a different position in some of the details and Fig. 3 an elevation of the fuse seen in the direc tion of the arrow in Fig. 1.
The turn-cock B is revolubly mounted in the bod of the fuse A and the axis of revolution of the cock B intersects the longitudinal axis of the fuse at right angles. In order to secure the cock against displacement. a ring C is provided and threaded in the body of the fuse. which ring incloses a tapered part b of the turn cock. The inner end of this turn-cock B has a recess wherein the rear end of the impact hammer D. containing the fulminate (Z enters. The recess 5 is made so large that of the inner end of the turn -cock B,
remains. A retarding charge 6 is arranged in the tongue ZR. which charge is inserted in the passage leading from the impact hammer to the bursting charge of the shell, as is illustrated in Fig. l. with the therein shown position of the turn-cock. With this position of the turn-cock. the mark I). located on its outer face. registers with a mark provided on the ring C. The end of the impact hammer D entering the recess 6 is shaped in such a manner as illustrated in the drawing. that the turn-cock ma be turned to either side of its position. as located in Figs. 1 and 3. that the tongue b as shown in Fig. 2 will open the passage for the ignition flame coming from the impact h a in me r.
The mark If of the turn-cock B registers with a mark (1- according to the angular position illustrated in Fig. 2: and it registers with the mark of the ring C when the turn-cock is revolved from the position it has in Fig. 1 into a position symmetrical to the position it has in Fig. 2 as regards the longitudinal axis of the fuse. The turn-cock B is furthermore provided with two channels 71 and Z). The channel 5 penetrates the tapered part b of the turncock and connects the time train E and the bursting charge of the shrapnel. when the cock B is turned into such an angular position, that the mark 0 registers with the mark 0 The channel If leads from the conical surface of the tapered part 7) in an inwardly inclined direction and terminates in the recess Z1 to one side of the tongue 6 As shown in Fig. l. the arrangement is such. that the channel 7)7 connects the time train with the channel leadingto the bursting charge of the shell when the turn-cock has the position wherein the mark 5 registers with the mark 0 If the mark 0' registers with the mark a. the time train will he cut off from the bursting charge of the shell as well as from that of the shrapnel.
As will be evident from the above description. th fuse will act on impact firing with delayedaction. compare Fig. 1 when the mark b registers with the mark 0; and without delayed-action. see Fig. 2 when the -mark 5 registers with either mark 0 or c.
When firing with the time train. shrapnel or shell act-ion will be obtained depending on whether the mark 6 registers with mark 4" or mark 0 Should the projectile prematurely meet with an obstructionduring time train firing. the impact hammer will in both cases cause instantaneous ignition.
By means of the recess 6 it is possible to place the impact hammer so close to the lair-sting charge of the shell, that with the fuse, having a retarding eharge, said mem her being provided with passages and adapted to connect and disconnect the time train of the fuse with the bursting charge of a shell and a shrapnel respectively.
2. In an impact fuse, a delayed-action device comprising a revoluble member in said fuse, having a retarding charge, said mem ber being provided with a channel adapted to connect the time train of the fuse with the bursting charge of shell, with said member in one position; and cut out the passage of the igniting flame from said time train to said bursting charge, with said member in another position.
In an impact fuse, a delayed-action vice comprising a revoluble member in said fuse, having a retarding charge, said member being provided with a longitudinal channel connecting the time train of the fuse with the bursting charge of the shell, with said member in one position, the axis of revolution of said member being perpendicular to the longitudinal axis of the fuse.
4. In a combination impact and time fuse having a time train and an impact hammer; a turn-coclgsitua'ted with its axis at right angles to the axis of the fuse; a recess at the inner end of said turn-cock forming a projeoting tongue inserted between said hammer and the bursting charge of the shell, a retarding charge in said tongue; said tongue causing delayed-action in the fuse when said tongue is situated centrally relative to said hammer; a free passage for the flame from said hammer, when said tongue is turned to one side, said turn-cock simultaneously connecting one and disconnecting another passage from said time train to either of the bursting charges for the shrapnel and the shell.
5. In a combination impact and time fuse having a time train and an impact hammer; a turn-cock, situated with its axis at right angles to the axis of the fuse; a recess at the inner end of said turn-cock forming a projecting tongue insertedbetween said hammer and the bursting charge of the shell, of a retarding charge in said tongue; said tongue causing delayed action when said tongue is situated centrally relative to said hammer, and causin free passage for the flame from said hammer to a bursting'charge,
when said tongue is turned out of its central position; a transverse channel in said turn-cock and a longitudinal channel there in; said transverse channel connecting the time train of the fuse with the bursting charge of the shrapnel when said turn-cock stands to one side of the central position; and said longitudinal channel connecting said time train with the bursting charge of the shell when said turn-cock stands to the other side of the central position.
