Z/ 2 2 5' /Z i 1 s a 1 d 1 /9 di 2- d 9 9 a $0/ i $2/ The constructional-form shown in Figs. 2 and 4 differs from that shown in Figs. 1, 3,5 and 6 to the extent that the central part 2 of the casing is thicker and that the part thereof situated between the

rings

18, 19 reaches as far as parts 1, 3 of the casing. ln this case the sleeve 24, which is situated in the boring in part 2 of the casing is naturally dispensed with. Y

The constructional form in accordance with Figs. 7, 8 and -9 differs from the former constructions to the extent that inthis case the sleeves of the

ratchet gear

10, 11 are not mounted in parts land '3 of the casing but in the central part 2 of the casing, for which reason parts 1 and 3 are solid and the central part 2 of the casing is hollow `in order to receive the ratchet sleeves 10,711 and the ratchets 24 which are actuated by the springs or pawls 23. Here also the parts of the casing are held together by a closing plate 5, which is secured by means of the screw 4 which is surrounded by a spiral spring 22. lIn this case also the

sleeves

10 and 11 are fitted internally with a pin 17. In this instance, the face of the

sleeves

10, 11 is smooth, while a pin is fit-ted on the circumference of the sleeves which projects beyond the casing 2, the said pin working in conjunction with grooves 26 provided in the wall of the boring of the

rings

18, 19. (See Fig. 11.)

In all the above constructional formsthe u per surface of part 1 ofthe casing is provided with a recessed portion 27.

The lock according to thepresent invention is completed by the bow 28, both Shanks of which are provided with longitudinal grooves 29 and circumferential groovesBO,

The method of operating the lock is as follows: y

The

rings

18, 19 are first of 'all set to the previously determined figure. For this purpose the closing plate 5 is turned transversely to part 1 of the casing. Part 1 of the Casin now rises under the action of the spira spring 22, so that the

rings

18, 19 can be -turned to the left, without their teeth engaging in the toot-

hing

13, 14 of the

sleeves

10, 11, that is to say; the

sleeves

10, 11 do not turn with them. Then the

sleeves

10, 11

are in the position of rest the pins 17 in their interior, are opposite to the longitudinal groove 29 in the'bow 28,'so that no obstacle exists tothe insertion of the bow into the lock. Thus, when the

rings

18, 19 have been set, with the screw 4 loosened, the screw 4 is tightened up once more. The ratchet wheels of the

rings

18, 19 now-` engage with the

ratchet wheels

13, 14 on `the face of the

sleeves

10, 11. When the

rings

18, 19 are set in posit-ion the bow 28 is inserted, in which process the pins 17 slide along in the longitudinal grooves 29. When the bow 28 is fully inserted, the

rings

18, 19 are turned to the right, and the lock is thus closed, as the

sleeves

10, 11 rotate with the

rings

18, 19, and the pins 17 enter the circumferential n grooves 30 in the bow 28.

'until the nose-pieces 2O thereon come under the nosepieces 21 on the parts of the casing, which can be detected in the darkwith the finger. vWhen this is effected, the

rings

18, 19 are turned further to the right so as to set them to the previously determined figure. The friction of the spring 23 rubbing against the teeth of the

sleeves

10, 11,"will cause a noise during the rotation of said rings. But, as a tooth 12 corresponds to each figure, after the

rings

18, 19 have been set so that the

nose pieces

20, 21 are in line, they must be still further turned so that the number of clicks produced corresponds to theV previously determined figure on the ring. For eX- ample, if one ring is set to the Figure 6, that ring will be adjusted to the figure required after six clicks. If the

rings

18, 19 should lbe turned backwards in consequence of the action of the springs 23, the

rings

18, 19 can be set not only by hearing, but also by impact, that is to say: by the sense of touch.

On the same pattern it is also possible to lconstruct locks suitable for doors, boxes and other articles of furniture.

We claim:

1. A keyless lock of the kind which can be set without removing the parts thereof and can be-opened by means of hearing or touch and having 'a plurality of casing portions `assembled by a screw and character bearing rings arranged therebetween, characterized by a casing closed by a pivotal closing pla-te and by sleeves carried by the rings and having ratchetv teeth upon their circumferential surfaces.

2. A keyless lock of the kind which can be set without removing the parts thereof and can lbe opened by means of hearingy or touch and having a plurality of casing portions assembled by a screw and character bearing rings arranged therebetween, characterized by a casing closed by a pivotal closing plate, sleeves carried by the rings and having ratchet teeth upon their circumferentialsurfaces, said teeth being engaged by springs secured to a casing portion, substantially as and for the purpose stated.

3. A keyless lock of the kind which can be set without removing the parts thereof and can be opened by means of hearing or touch and having a plurality yof casing por tions assembled by a, screw and character a` spiral spring arranged between the pivotal bearing rings arranged therebetween, charolosing plate and a casing portion, subacterzed by a easing closed by a pivotal stantally as and for the purpose stfitecl.V closin@ plate sleeves carried by the rinfrs 5 and hving rttehet teeth upon their eircuri- SAMUEL KORN ferental surfaces, said teeth being engaged 1 i DLSIDEB SAAHL by springs secured to a casing portion, and EMIL NADOR.
