SPECIFICATION forming part of Letters Patent No. 528,651, dated November 6, 1894. Application filed January 9, 1894.. Serial No. 496,235. (No model.) Patented in France August 2,1893, No. 232,074.

To whom it may concern.-

Be it known that I, J ULES BOIS, notary, a citizen of the Republic of France, residingat 31 Rue de IHdtel-de-Ville, Lyons, in the Republic of France, have invented certain new and useful Improvements in Combination- Locks, (for which I have obtained a patent in France, No. 232,074., bearing date August 2, 1893,) of which the following is a specification, reference being bad to the accompanying drawings.

This invention relates to a keyless combination lock which is adapted to be used for locking various articles, such as belts, chains, account books, pocket books, money bags, portmanteaus and the like. As the principle upon which the construction of this look is based is the same for these various applications I will confine myself to describe and represent the same by way of example as applied to a belt.

In the accompanying drawings,-Figures 1 and 2 show an elevation and a plan of this look mounted upon the belt. Fig. 3 shows a section taken on the line 1-2 of Fig. 2. Figs. 4. and 5 are plans explanatory of the operation, the upper closing plate of the lock being in these figures supposed to have been removed. Figs. 6, 7, 8, and 9 represent views of some parts of the look.

This lock substantially comprises:

(First) A box A in which I arrange the combination system and the bolt hereinafter referred to. It has on the prolongations of its sides at one extremity an axis a upon which is slid and fixed by sewing or otherwise one of the sides of the belt to be locked, and at the other extremity an ordinary tongueB designed to engage with one of the holes in the belt, and a rocking part 0 which when the lock is closed is turned back upon the tongue (position Fig. 3) and held in this position by the bolt of the lock, thus preventing the disengagement of the tongue from the belt. This part 0, which, articulated at 0 and having for example the shape represented in Figs. 2 and 3, carries an arm forming a prolongation which is bent twice at its extremity, first downward and then inward in order to enable the 50 bolt to take above this extremity and pre- V out out in its middle, which separates the co mvent it from being raised to disengage the tongue from the belt. In lieu of a single bolt use may be made of two. In this case the part 0 carries at each of its extremities a curved arm instead of the single one mentioned. The box A has on each of its other two sides an opening for the passage and the operation of the combination system. This boxA is closed by means of a plate D, Figs; 2, 3, and 6, which, being provided with a catch E pivoted at e, can be removed from the lock, for changing for instance the combination, only when the bolt is moved to the rear, that is to say when the lock is open. This plate D is held at the rear by a tenon or tongue .9 adapted to engage with a'slot provided in the correponding side of the box, and in front by the said catch E adapted to engage with a corresponding openingformed on the other opposite side of the box, which catch can be brought to the position indicated by dotted lines in Fig. 6, that is to say, disengaged from the box A, only when the lock is open. The plate D has on its under side a partition 61 bination system from the bolt of the lock.

7 (Second) The combination system constituted by plates G which may be changed at will and varied in number according to the number of combinations it is desired to have at disposal. These plates, which in the lock represented are four in number, present on the side toward which they must be drawn a bent part 9 for enabling them to be operated easily. They are also provided on one of their faces with teeth w serving as marks for their engagement across the box of the lock',1and withja' recess 9 in which the bolt can freely move back, that is to say, open the look when all the recesses in the plates correspond. These severalplates are held in the position which each of them is caused to occupy, by springs H, Fig. 9, formed of slightly curved strips of metal, which are interposed between each two plates and separate themfrom each other. In order that as broad springs as possiblemay be'u'sed without interfering with the back movement of the bolt, recesses it have been provided. 7

(Third) The boltNof the lock, represented {00 more particularly in detail Fig. 7. This bolt, which is here actuated by the aid of the head or knob n fitted to be displaced in a slot formed in the plate D, carries upon its opposite face a tongue at which enables the bolt to disengage the rocking part 0 only when this tongue can pass at the same time through the recesses g in the plates G. "When after the recesses g in the plates having been provided at the desired place the lock is to be opened at certain numbers the latter are placed in the box A in the desired order so that the several figures by their grouping may constitute the number chosen for example 1,324. All the recesses 9 having been put in correspondence, 1 mount the bolt, taking care to engage the tongue at with these recesses. Then I fix the closing plate D, causing the tenon s and the catch E to engage with the corresponding sides of the box of the lock. The belt having been tightened and engaged with the tongue, the rocking part 0 is turned back upon the latter (position indicated by dotted lines in Fig. 3), then the bolt moved forward in order to be placed above the extremity of this rocking part and prevent it from being raised. The several plates are then completely engaged with the box of the look, as shown in Fig. 1, which has the efiect of fixing the combination. For opening the lock afterward it will be sufficient first to completely draw back all the plates on each side, then cause the plate having a recess for the figure l (designated by 1 in the drawings) to engage with one tooth in the interior of the box, next cause the plate having a recess for the figure 3 (designated by 2) to engage with three teeth, then cause the plate having a recess which corresponds to the figure 2 (designated by 8) to engage with two teeth, &c., with all the plates, so as to bring all their recesses in correspondence and permit the tongue 11 in the back movement of the bolt to pass at the same time through all the recesses (Fig. 5) which back movement being efiected by the aid of the knob n releases the part 0 which is then raised in order to cause the tongue B to disengage from the hole in the belt into which it had originally been passed.

According to the number of combinations it is desired to have or the difficulties to be raised in the opening of the look I may employ a greater or smaller number of plates and provide these with a greater number of notches, which latter and the recess may be formed either on the same side or on both sides of the plates. The engagement of the plates with the interior of the box is effected by the aid of the notches so in the plates and a bevel on the side of the box against which the teeth are allowed to escape. If desired each notch may be numbered.

It may be observed that the belt provided with such a system of lock can be employed simply as an ordinary belt, that is to say using only the tongue, which in this case, instead of taking below the part O,is left above.

As before stated the construction of this look may be varied according to the uses to which it is to be applied. Thus for account books the axis a will be dispensed with and replaced for example bya plate mounted by a hinge and connecting the box of the lock with the cover of the book. The tongue B and part 0 will likewise be dispensed with and replaced by a suitable ring or the like fixed to the opposite cover, with which the bolt or other kind of hook of the lock engages.
