Application filed March 7, 1916.

V larly to a lock for same.

The object of the present invention is to provide a container and dispenser for interleaved papers and particularly a simple, cheaply manufactured easily operated keyless lock for same which cannot be opened except by one'familiar with or instructed in its operation.

Further objects will hereinafter appear. The invention consists of the parts and 'the construction and combination of parts,

as hereinafter more fully described and.

claimed, having reference to the accompanying drawings, in which Figure 1 is a perspective view of the interleaved paper container and dispenser. Fig. 2 is a central, vertical section through same, showing the application of the keyless lock. Fig. 3 1s a cross section taken on line 3-3, Fig. 2.

Referring to the drawings in detail, A indicates the container proper, consisting of a back section 2, two side plates 3 and a bottom section 4, which is provided with a longitudinally disposed slot or opening 5 through which the interleaved paper sheets may be removed. Pivotally attached to the side plates 3, as at 6 is a cover section B, consisting of a front plate 7, twoside plates 8 and a cover section 9. The pivotal mounting of the cover section B permits it to be turned from the closed position shown in Fig. 2 to the dotted line position indicated at 10, when it is desired to refill the container.

The main novelty of the present invention consists in the. provision of a keyless lock which is provided for the purpose of securin the cover section with relation to the contalner A, when in the closed position. The construction of this lock will be as follows: Pivotally attached to the under side of the cover 9, as at 11, is a pair of latch arms 12,. One end of each latch arm is Specification of Letters Patent.

provided with a hook-shaped projection 14, which in this instance is adapted to project through an opening 15, which is formed by cutting away a portion of a downwardly turned flange 16, formed onthe back section 2 of the container. The hook-shaped ends of the latch arm will normally tend to scparate in the direction of the arrows to engage the opposite flange sections 16, thus securing the cover with relation to the container. This is accomplished by providing a U-shaped spring 17 This spring is car ried or suitably secured upon the pivot pin 11 and its outer ends are bent and extended to engage with the free ends 18 of the latch arms, as shown in Fig. 3. A stop 19 has been provided for the purpose of limiting the movement of the latch arms about the pivotal point 11. Formed near the ends 18 of the latch arms is a pair of semi-circular depressions 20, which are positioned directly in register with a circular-shaped opening 21, formed in the cover section 9. This opening is provided for the purpose of permitting the insertion of a pointed pencil or similar shaped device, which when inserted passes through the o ening formed by the semi-circular depresslons 20 to assume a position intermediate of the ends 18 of the latch'arms, where a downward move ment of the pencil point will separate the latch arms and cause same to assume the dotted line position, indicated at 22. This brings the hook-shaped ends 14 out of engagement with the flanges 16, thus permitting the cover section to be swung back about the pivot 6 to assume the position shown at 10. The pencil or other device employed for the purpose of separating the latch arms, or in other words, releasing the lock mechanism may be removed the moment the cover section is released and partly swung'back about the pivot 6. The container may now be filled with the interleaved sheets and it will then only be necessary to swing the cover section back to closed position. This brings the hookshaped ends of the latch arms back into register with the flanges or shoulder 16,

manufacture and consumes a comparatively small space within the container this being.

of considerable importance as itcorrespondin 'ly increases the capacity of same.

'I he look as before described is opened merely by the insertion of a pencil and can therefore be easily opened at any time without the use'of a key. The lock mechanism being positioned directly under the cover is entirely inclosed and hidden. Its mechanism can therefore not be seen or reasoned out by unauthorized persons who might otherwise have a tendency to tinker with or destroy the mechanism.

The materials and finish of the several parts of the device may otherwise be such as the judgment and experience of the manufacturer may dictate.

I wish it understood that various changes 'in form, proportions and minor details of Copies of this patent may be obtained for section pivotally mounted thereon having a small circular pencil-receiving opening, and a keeper on the container, of a lock carried by the cover section and adapted to be operated by the pointed end of a pencil and the like, said lock consisting of a pair of centrally pivoted arms carried by the cover and recessed at their forward ends in alinement with the cover opening,

latch members formed on the opposite ends of the arms for engaging with thekeeper, spring means normally tending to hold the for ard ends together, and a stop pin disposed between the recessed end portions of the arms to hold the recesses in alinement with the cover opening and in slightly spaced relation, said stop pin further retaining the arms from swinging bodily about their pivotal mounting and thereby hold the latch ends properly disposed for reception by the keeper.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
