CHARLES EMILE ALEXANDRE ALEXIS DENY, OF PARIS, FRANCE.

LOCK.

SPECIFICATION forming part of Letters Patent No. 448,912, dated March 24, 1891.

Application filed June 9,1890- Serial No. 354,855. (MorleL) Patented in France March 9, 1889, No. 196,5t35, and in England May 3,1890, No. 6,873. I

To all whom it may concern.-

Be it known that I, CHARLES EMILE ALEX- ANDRE ALEXIS DENY, of Paris, Department of the Seine, in the Republic of France, have invented Improvements in Mechanism for Looking and Bolting, (for which I have obtained Letters Patent in France, No. 196,585, dated March 9, 1889, and in Great Britain, No. 6,873, dated May 3, 1890,) of which the following is a specification.

The improvements forming the object of the present invention relate to looks and safety-bolts, and are connected more particularly with the employment of a barrel of peculiar form designed with aview of reducing the dimensions of the keys and obtaining greater security.

In the accompanying drawings, Figure 1 represents in elevation, with face-plate removed, one kind of a lock which may be provided with a barrel constructed according to my invention. Fig. 2 is a longitudinal section of the barrel. Fig. 2 is a front view of the barrel. Fig. 3 represents a key adapted to be used in the barrel shown in Fig. 2. Figs. 4 and 5 are views of the disks used in the barrel. Fig. 6 represents the part of the lock immediately behind the barrel. Fig. 7 represents a lock provided with a modified form of barrel. Fig. 8 is a sectional plan of Fig. 7, taken on line 8 S. Fig. 9 is a section taken on line 9 9 of Fig. 7. Fig. 10 represents a key adapted to be used in the barrel of the lock shown in Figs. 7, 8, and 9. Fig. 11 is a view of a detail.

My improved barrel attachment may be applied to Various forms of locks, and it is so constructed that one small key may be provided for the opening of locks of quite diiferent character, except as to the barrel itself.

The barrel B (represented in Fig. 2) is to be fixed to the cover-plate of the lock, and it is provided with two longitudinal grooves y y, and an entrance 0 of small diameter with a radial slot or slots for the passage of a small key with two bits, Fig. 3. Washers 0, Figs. 2 and 4, are packed together in suitable numbers in the barrel and held therein by a ring or washer 0, Figs. 2 and 5, secured by screws or otherwise to the barrel. To prevent the rotation of the washers 0, they are provided with radial projections d d, which enter the grooves y y in the barrel. Every washer c is provided with a radial slot 0 and a central hole for the passage of the key. These slots correspond or coincide radially with the slots in the front end of the barrel, and the central holes, being of difierent diameters, constitute a species of circular comb or notched chamber fitting the bit of the key. The fixed ring or washer c is likewise provided with a slot and a hole; but the slot does not coincide with the slot in the entrance, being set at a different angle. It results from this arangement that the key when pushed into the barrel is stopped by this fixed washer c, and the key cannot be turned unless the openings in the centers of the other washers correspond perfectly with the form of the bits of the key. Each Washer c has a second slot 0 which coincides with the slot in' the washer c. If the washers 0 correspond with the bits of the key, the key can be turned in the barrel until its bits are at such an angle as to enable it to enter the slot in the fixed washer, through which it has to pass in order to enter the lock. If the fixed washer 0' should not be used, the second radial slot 0 may be dispensed with. It can thus be seen that it becomes possible to furnish locks of different combinations and to have for each of them a special key, and also to have a key which will fit all the combinations.

In the interior of the lock and covered by the barrel there is a lantern-piece L, Figs. 2 and 6, likewise provided with a radial slot for the reception of the bit of the key with which it becomes connected. This lanternpiece is capable of rotation and is provided with a false bit to act on the talons of the bolt and on its levers or plates (when such are employed) to move the bolt.

The barrel or tube presents the advantages of being unpickable and of great strength, all its parts being fixed, and it requires a key of relatively very small dimensions.

For greater security a wardd disk a. may be provided on the front or back of the fixed ring 0. This disk Ct is shown in Fig. 11 as provided with projections a a to act as wards with which the bit of the key must correspond, as indicated by dotted lines in Fig. 3, in order to rotate.

The barrel B can be applied to a safetybolt and act in combination with a rotating knob or handle connected to the lantern L, which receives the action of the key and transmits it to the bolt, as indicated in Fig. 6.

Fig. 1 represents the barrel B as applied to a lock having a forked boltA with two heads or a capable of a throw of two turns and a half. The other turns are obtained by means of the key and the lantern-bit L, while the half-turn is obtained by an additional movement of the key from the outside and by the sliding knob M on the inside.

In cabinet or furniture locks of small size the barrel or tube is preferably constructed in the manner represented in Figs. 7, 8, and 9. In these figures the key-barrel B is a flat tube of rectangular form in transverse section with a symmetrical or regularly-formed opening or entrance for the insertion of the double-bitted key. It is perforated at its upper and lower sides with stepped or notched openings c e in place of the comb or steps formed by the stationary washers c, of the construction before described. thus formed acts in the same manner as the cylindrical barrel before described; but its construction is more simple and more eco nomical. Of course the steps or notches in the openings 6 6 must be of corresponding form to the bits of the key, Fig. 10, in order that the latter may turnfreely, and the openings are different in each lock, which thus retains its individuality. The boltA is forked and the legs pass on opposite sides of the tube. One leg carries the talons, which are acted on by outer bits of the key, and the other is provided with notches engaging with the stop-spring R. The key, after being turned so that the bits pass through and project from the openings 6 e in the side of the flattened tube, acts simultaneously and in opposite directions on the bolt and on an anti-friction roller 1) on the spring catch or stop R. The movement resulting from this action is very smooth, the resistance to be overcome being balanced or equalized. In order to obtain further security, a thin plate or curtain m covers the talons of the bolt and opposes the introduction of a pick, and with the same object the bowl or anti-friction roller b on the spring'catch on the opposite side can be arranged at any desired level facing the notched or stepped opening.

Cabinet-locks constructed under these conditions are of great strength, but at the same time devoid of complication, and present per.- fect safety, as hereinbefore explained.

In conclusion, it should be observed that all the parts embodying niyinvention can be composed of any suitable metal and be of any The barrel suitable shapes and dimensions. I do not limit myself as to their combination or grouping and connection, which may be modified according to circumstances and conditions arising from practice and in accordance with the type of lock in which they are employed. For example, the comb or stepped chamberin the barrel, in place of being formed with washers c, placed one over the other in suitable numbers, may be formed of a single piece obtained by any suitable means and corresponding to the notches or steps in the bits of the key.
