SHELL-FUSE.
Specification of Letters Patent.
Patented Sept. 21, 1915.
Application led June 2, 1915. Serial No. 31,777.
To all whom it may concern:
Be it known that I, ERNST FABER, engineer, a subject of the German Emperor, residin at Barbarossastrasse 49, Berlin, W. 3v., ermany, have invented certaln new and useful Improvements in Shell-Fuses; and I do hereby declare the following to be a full, clear, and exact descriptlon of. the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Shell fuses are known in which the cover is connected with the fuse body by means of a spring locking ring engaglng a groove on the outside of the fuse body and at the same time a groove on the inner side of the fuse cover. This device has the disadvantage that it is not possible to disconnect the cover from the body without destroying the cover.
My invention has for its object to avoid the said disadvantage in shell fuses of the said kind. For this purpose I arrange beneath the groove of the cover engaged by the spring locking ring a second ring connected with the fuse cover by means removable from the outside of the cover so that' after removing the fastening means the cover can be removed fromthe fuse body.
In the accompanying drawings I have shown an embodiment of my invention. Figure 1 is a longitudinal section through the fuse omitting the inner parts thereof. Figs.4 2 and 3 are similar sections through a'part of the fuse representing the connection between the second ring and the fuse cover on a larger scale in two different positions.
1 is the fuse body and 2 thefuse cover provided with a circular inner groove 3 engaged by a spring locking ring 4 which engages also an outer groove 7 of the fuse body thus preventin the cover to be removed from the fuse ody. The lower Wall of the groove 3 is however formed by a separate ring 5 connected with the fuse cover by two, three or more bolts 6 which on the inner side of the cover are inserted into recesses of the ring 5 and which are hammered from the outside of the cover.
In order to bring the cover on to the fuse body the spring locking rinlll is inserted into the groove 7 'of the se body and pressed together so as to allow the cover to be put over. As soon as the groove 3 of the cover is opposite the groove 7 of the fuse body the ring 4 spreads outwardly by means of its spring action. Therefore the cover is held firmly on the fuse body.
In order to remove the cover from the body the bolts 6 are driven inwardly from the positionshown by Fig. 2 into the position shown by Fig. 3 whereby the rin 5 is disconnected from the cover 2. Therefgore the latter can be removed freely from the fuse body.
In order to allow the bolts 6 to be driven far enough inwardly the fuse body may be provided behind the bolts with recesses as 1s shown by dotted lines in Fig. 3.
Having thus described my invention what I claim is:
,In a shell fuse the combination with the fuse body of a fuse cover, a groove on the inside of the cover, a groove on the outside of the fuse body, a spring 'locking ring engaging the said grooves and a second ring connected with the fuse cover by means removable from the outside of the cover so as to disconnect the second ring from the cover.
In testimony whereof, I havesigned this specificationv in the presence of two subscribing witnesses.
ERNST FABER.
