Description

Feb. 13, 1934. A. DABRASKY FUSE SETTING MACHINE Original Filed Jan. 4. 1952 I INVENTOR. Aug usi Ilahrask By M I TTQRNEY Patented Feb. 13, 1934 Original application January 4, 1932, Serial No. 584,611. Divided and this application March 15, 1932. Serial No. 598,976
1 Claim.
(Granted under the act of March 3, 1883, as
amended April 80, 1928; 370 O. G. 757) The invention described herein may be manufactured and used by or for the Government for government purposes, without the payment to me of any royalty thereon.
This invention relates to a fuse setting machine and is a division of copending application Serial No. 584,611, filed January 4, 1932, which has resulted in Patent No. 1,898,081, issued February 21, 1933.
1 The fuse setting machine shown in the parent application is of the type disclosed in Patent No. 1,640,392 in which two relatively rotatable adjust ing members are adapted to be coupled to a fixed and a movable part of the fuse of a round of am munition.
The improvements proposed in this invention are directed to the coupling means and consist in the convenient arrangement of a pair of opposed levers and their direct actuation by a single spring.
To these and other ends, the invention consists in the construction, arrangement and combination of elements described hereinafter and pointed out in the claim forming a part of this specification.
A practical embodiment of the invention is illustrated in the accompanying drawing, wherein:
Fig. 1 is a longitudinal sectional view through a portion of a fuse setting machine equipped with the improved coupling means.
Fig. 2 is a sectional view on the line 22 of Fig. 1.
Fig. 3 is a view in side elevation of the time fuse for which the machine is designed.
The fuse setting machine is only partially illustrated as its complete structure is shown in the 3 patent previously referred to. For the purpose of this invention the machine consists of a pair of coaxial and independently rotatable adjusting members A and B. The member A is adapted to be coupled to the lug 5 on a fixed part of the fuse by means of levers 6 while the member B is similarly coupled to the lug 7 on the rotatable time ring 8 by means of levers 9.
The levers 6 and 9 and their arrangement are identical and consequently only one set will be described. Referring to Fig. 2 the adjusting member B is formed with a transverse slot 10 positioned adjacent the rear end. The slot extends through the w all of the adjusting member a suflicient depth so that the levers 9 mounted in the slot will project into the interior of the adjusting member and be in position to engage the lug 7 on the time ring 8.
The levers are each mounted on a pin 11 which may be conveniently inserted in aligned apertures from the end of the adjusting member. A pin 12 mounted similarly to the pins 11 at a point midway thereof supports a double armed spring 13. Each of the arms 14 of the spring acts on one of the levers and normally holds it against a stop 15 formed by the walls of the adjusting member. The inner end of each lever is formed with a recess 16 and the two recesses cooperate to accommodate the lug 7 of the fuse. A cam face 17 on each lever is disposed on the side of entry of the round of ammunition so that the lug 7 may be moved into the plane of the levers.
When the round is inserted into the machine the lugs 5 and 7 of the fuse have no specified position relative to each other or to the sets of levers 6 and 9. Assuming that the lugs have been inserted in such a position that they are not engaged between the levers then when the adjusting members are rotated the near lever will engage the lug and be rotated against the action of the spring. As soon as it has cleared the lug it will snap down behind it and the lug will be confined in the recesses 16 in adjoining ends of the levers. Upon continued rotation of the adjusting member the lug and the part of the round to which it is attached will also be rotated.
I claim.
In a fuse setting machine, a rotatable adjusting member having a transverse slot adjacent one end, a pair of opposed levers pivotally mounted at the end of the slot and having their inner ends projecting into the interior of the adjusting member, said levers intermediately engaging the wall of the adjusting member to limit rotation inwardly, a pin positioned above the free ends of the levers,
and a spring carried by the pin and having an arm engaging each lever.
