SHEELS OR THE LIKE.

Application filed May 3,

To all whom it may concern: 7

Be it known that I, KARL Vinim-zn, en- ;gineer, a subject of the German Emperor, residing at 17 Jiilieherstrasse. Dusseldorf,

(1erinany, have invented certain new and I iiseful linproi'enients Relating to Automatieally-Operating Keys for Setting the Timing-Rings of Fuses for Shells or the Like; and I do hereby declare the following" to he invention, SIKll will enable others skilled in the art to which it appertains to make and use the some.

The present invention relates to operating keys for setting the timingrings of fuses tor shells or the like of the hind having two relai irely movable parts, whieh parts are set with certainty upon the desired division of a scale earried by one of the parts by the autinnatio engagement of a bolt with a corresponding rack.

In known construrtions of this kind the arrangementof the holt has heen such that when the timing ring is being set an unintentional pressure of the finger or a shock might cause the bolt to heeome disengaged from the rack and thus render the setting of the timing ring inaccurate.

The presentinvention has for its object the provision of means for obviating this clisatlvantage, the bolt being so arranged that when the timing ring hein; set the bolt will be prevented from moving from its locked position.

The invention will be hereinafter fully setforth and particular]; pointed out in the claims. In the accompanying drawings Figure 1 is a longitudinal SBCLlOll through the key on line 1-l, Fig. 2. Fig, 2 is a plan 'VlGW, with parts in section, on line Fig. 5} is a sectional viewo't' the handle and ring. Fig. i is aplzrn VlEW thereof.

Referring to the drawings, a ring I) is fixed to the handle a, or is, preferably; made in one piece therewith. In this ring I) is an adjustable slide a. This slide carries a pro jeetion a neoessoi s for setting the timing ring of a fuse. The movement of the slide a V 'antl'its projection (Z can toe-read on the scale 7? by a pointer 6, so that. any necessary correction in the positioning of the fuse can be made.

{The ring 5 is surrounded by asecond ring p', which latter has an inwardly projecting Specification of Letters Patent.

& against the first-named ring. A'tliird ring 2' serewed into the ring" f/ eonneets the latter with the ring h in such lllfilillt?! ll1tli the two rin 's can be rotated relatively to each other, but cannot be dis- 5 placed axially.

0n the ring g is a second projection r necessary for setting the fuse, and this ring also has ailixed thereto annular scale 7;, While the ring I) eerries an index according to which the necessary period combustion tor the fuse may he set.

The ring 5 has on its inner periphery a series of teeth I wlii correspond exactly with the division marl oi the annular scale. intermediate teeth may als ritled which correspond with semi of the seale. llith the tooth in on n hel he more ally in the ring Ti .r the pr enre of :1 spring 0 which keeps tooth '22v engaged with the ring (7-. ll hen two rings required for setting the fuse to he relatively displaced the P i of hand holding the handle 1/ pres. agai the roughened surface 71 01" the bolt m so as to disengage the tooth or from the teeth 1 of ring ll hen the two rings have heen adjusted the holt m is released by removing pressure from the surface 7) and the rings are again automatically locked.

The bolt in abuts against the periplier of the fuse (as shown in dotted lines i Fig". l) when the latter is in position in key. The fuse itself therefore preve is holt m from shitting; toward th inidi'llo oi the key and thus provides dist-onneetimi of the adjusted parts. 7

I claim my invention:

1. In automatically operating hey in setting time Eases on shells or the like, tl combination of two rel iively parts, one of which is movable member of the it l flange 1i lying a roarrlecl by riecl by one of the parts, it bolt, the same part, a reeln carried or the other part and means for holding tie bolt in enpart, with which the bolt engages, and means for normally holding the bolt in engagement With the rack, a part of the bolt extending over the handle.

3. In an automatically operating key for setting time fuses on shells or the like, the

combination of two relatively movable parts, one of which is designed to engage a movable member of the fuse, a bolt on one of the contiguous faces of one of the relatively movable parts, a rack on the other relatively movable part, and means for holding the bolt in engagement with the rack.

4. In an automatically operating key for setting time fuses on shells or the like, the

combination of two relatively movable parts one of which is designed to engage a movable member of the fuse, ahandle on one of such parts, rack on the other of said parts, such rack surrounding the part having thehanclle, a radially movable bolt within the latter part, find means for holding the bolt in engagement with the rack.

In Witness whereof I have hereunto set my hand in. presence of two witnesses.

KARL OLLER.
