AUTOMATIC SETTING-KEY FOR SETTING THE FIRING-CHARGE RINGS 0F TIME-FUSES.
' Patented April 10,1906.
T0 40% whom it may concern:
Be it known that I, LEOPOLD BECK, director, a subject of the German Emperor, residing at 11 Dreyseplatz, Sommerda, Germany, have invented certain new and useful Improvements in Automatic Setting-Keys for Setting the Firing-Charge Rings of Time- Fuses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an automatic setting-key for setting the firing-charge rings of time-fuses, the essential feature of which consists in the provision of a ring situated between the other parts of the key, which after the coming in contact of the carrierstud of the key with the stud of the fuse is shifted to the right or left to an extent equal to the width of the said two studs, and thus enables the setting-key to be moved in any desired direction on settin the fuse, thus effectually preventing any lncorrect setting of the fuse caused by the turning of the key in the wrong direction, as has been liable to occur with the automatic setting-keys of known construction.
On the accompanying drawings, Figure 1 shows a vertical section through the settingkey on the line a b, Fig. 2. Fig. 2 shows a top plan view Fig. 3, an under side plan view; Fig. 4C, a vertical section through the ring A on line 0 d of Fig. 5 Fig. 5, a top plan view of the ring A Fig. 6, a vertical section through the ring B on line e f, Fig. 7; Fig. 7, an under side plan view of the ring B Fig. 8, an elevation of the complete setting-key; Fig. 9, an elevation of the fuse with the projectile-head. Fig. 10 is'a vertical section of a modified construction of the key, and Fig. 1 1 is a horizontal section on the line 9 h of Flg. 10.
The setting-key consists of four rings arranged concentrically one above the other, of which the setting-ring A, Figs. 1, 4, and 10, is provided with a handle a. At the upper edge the ring is recessed for engagement with the connecting-ring D. On its upper surface is situated a scale, Figs. 2 and 5, which corresponds with the divisions of the corresponding ignitin charge. The inner periphery of the rin is formed with two conical surfaces.
The handle a isconnected to the ring A by means of arms I). The openings between the arms and through the lower cone-surface of the ring A expose to a great extent'the di- The middle ring B, Figs. 1, 6, and 7, is
formed with a cylindrical outer periphery, while the inner periphery is formed conical, corresponding to the form of the fuse-head. The inner surface carries a stud (1, Figs. 1, 6, and 7, and at right angles to this a slot 6, the length of which corresponds with the total width of the stud f, the stud d of the middle ring B, and the stud 7c of the ignitin -charge ring E. It will be obvious that the s ot e and stud f may be transposed without alteration i in proportions or function.
The under surface of the middle ring B rests upon the ide-ring 0, Figs. 1 and 3, the lower part of t e inner periphery of which is formed to fit the head F of the projectile, so
as to afford a reliable guide to the key. On
the upper surface is a stop-stud f, 'Fig. 1, which engages with the recess 6 of the middle ring B. The ring C is provided with an external screw-thread for connection with the ring D, and below this it is formed with a necking for reducing the weight.
The connecting-ring D has its lower end screwed to the guide-ring C and engages, by means of an inner shoulder, with the recess of the ring A, by which means all four rings are secured together. A setting-screw g is provided for preventing an unintentional loosening. of the two rings after assembling, as shown at Figs. 1 and 10.
On the outer surface of the connecting-ring D is provided a projection h, Fig. 2, in which is formed a radial screw-threaded hole for the reception of the setting-screw i, for fixing the ring A after the adjustment of the settingkey. On the upper surface of the said projection is marked an arrow, Fig. 2, to which the ordered division-line of the scale of ring Ais adjusted. If now the rings A and D are Ice prevented from shifting relatively to each other by screwing up the setting-screw i and the setting-key is so mounted on-the fuse that I I O the notch c of the ring A fits over the stud: 7c of the igniting-charge ring E, then on turning the setting-key the ring E will be carried round with it until the stud d of the middle ring bears against the stud Z of the fuse-plate G. At this moment the setting of the fuse is not yet completed, because there is wanting in the turning motion of the lower ignitingcharge ring an amount equal to the width of the two studs (1 and Z before the said divisionline can be made to agree with the markon the fuse plate G. Owing to the arrangement of the elongated recess or slot 6 in the middle ring B, the ring A can be turned further to the extent of the said recess, which, as above stated, is equal to the width of the two studs, until the stud f stops the further motion, while at the same time the desired division-line is brought to correspond with the setting-mark of the fuse-plate.
It will be seen from the above description of the arrangement of the setting-key that in consequence of the movability of the ring B to the extent of the width of both studs (:1 and lbeyond the point of contact thereof the setting-key will with certainty effect a correct setting of the fuse, whether it be turned to the right or to the left.
Figs. 10 and 11 show a modification of the construction of the setting-key in which the ring C of the first-described construction is represented by the ring C. This ring C contains in its upper edge and at the height of the conical inner periphery a double recess 6, Fig. 11 having the function of the slot e, previously described, and in which is placed a concentrically-movable slide B, which takes the place of the middle ring B and which is covered by the ring A. This slide carries the extended stud d, which forms the double function of the studs (1 and f. The other parts of the setting-ring and the mode of operating therewith are the same as above described.
Having thus described the nature of this invention and the best means I know of carrying the same into practical effect, I claim- 1.
