Specification of Letters Patent.

Patented Sept. '7, 1909.

Application led AFebruary 8, .17859. Serial No. 476,620.

have invented certain new and useful Inl-- proveniente 1n Puzzle-Boxes, of which the following is a specification.

My improvements relate to boxes which can only be opened in a particular manner by the manipulation of the cover when the. box 1s reversed in position,`and the invention" consists in the specic construction andarrangement of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1, is a top view of my improved puzzleA box; Fig. 2, acentral longitudinal section on plane of line 2 2- Fig. l; Fig; 3, atop view of the box open, parts being broken away; Fig. 4, a transverse section upon plane of line 4 4- Fig. l; Fig. 5,.is a view similarto Fig. 2, the device being inverted; Fig. 6, a detail view of the underside end of the main cover.

The main cover C, is pivotally connected to one end of the box B by means of the pin a, the other end of the box being formed with a retaining projection a, and .flange a?, for the reception and retention of the other end of the cover, which latter is formed with the recess c, the sides of which iit over and engage the projection a', while,

the edge c', fits under the ange a2. VThe pivoted end of the main lcover is formed with the slot c2, through which the pivotca, projects, so as to allow of the necessary movement of the cover when it is openedor closed, in order to clear or engage with the" detaining projection a.

S, 1s a supplemental cover ,sectiowful'-l crumed on the pivot a, on which it turns but has no play or looseness'bein'g unlike .then cover C, in which provision is madefor longitudinal movement by the slot c2, as before stated. The lower part of the pivot a, is embedded in the box B, and its upper portion is embedded in the supplemental cover S, which is made of two layers or plates s, s', so as lto cover the upper end of the pivot a, and render it invisible.

The inner end s2, ofthe plate s, is at an angle considered transversely to fit a correspondingly inclined edge cl on the cover C. The plate s, is also formed with ay hole Zt,

of the outer 4which, when the supplemental cover S is in a closed position over the main cover C, coincides with a recess r, in the superstructure ofthe main cover C. Said recess r, contains abolt b, which, when the cover is uppermost, falls into the hole la, in the supplemental cover S, and locks the main cover C, and the supplementary cover S, together. Vhen however the box is reversed, with the cover underneath, the bolt b, falls back into the recess r, and the supplemental cover S may be turned laterally away from the main cover `@provided the slide e, on the superstructure of the ymain cover has been withdrawn. This slide c, is held to the superstructure of the main cover by flanges e c', and a stop c2, which rests in a slot c3 in said slide, thus providing for the longitudinal movement of the slide c. The ends c4, c4 of the flanges c', c', when the slide is closed, engage with corresponding ends S5, 85 of flanges on the supplemental cover S, and thereby preventcthe turning of the latter on the pivot a, until the slide c, is drawn outward.

Supposing the box to be closed, to open it, it is reversed with the cover underneath, in which position the bolt Z), drops into the recess r, and away from the hole L, in the supplemental cover S. The slide c, being 'then or previously drawn outward, the supplemental cover S may be turned upon the .pivot a. This releases the main cover, so that it may be slid back away from the retaining shoulder a. When the open box is turned upward, the bolt b, drops down and prevents the closing of the supplemental cover S, until the box is again reversed, so that the bolt drops back into the recess r, when theparts may be readily restored to therelative positions above described.

F is a fake slide on the supplemental cover S, corresponding to, and opposed to the -sli'de c, on the superstructure of the cover. Its object is .simply to confuse the uninformed manipulator of the box cover, and it performs no other function.

The box and cover thus constructed and arranged form an effective puzzle device which may be used not only for amusement but to elfectually prevent access to the contents of the box to all but those intrusted with the secret method of opening the same.

What I claim as my invention and desire to secure by Letters Patent is,

Apuzzle box B having at one end the retaining projection a and flange a2, and at the other end the upwardly extending pivot a, the main cover C, formed 'With recess c at one end for engaging the proJectlon a and with the longitudinal slot c2 at the other end, along, Which the pivot is adapted to move, also formed With a recess 9^, the bolt slolable in said recess, and the supplemental 4 cover S above a portion of the main cover BENOIT GERRY.
