Description

1'0 all whom it may concem:
CHARLES F. RAYNAUD, OF SAN FRANCISCO, CALIFORNIA.
FOLDING PAPER BOX.
Specification of Letters Patent.
Patented Nov. 19, 1907.
Application filed February 23- 1906. Serial No: 302,531.
Be it known that 1, CHARLES F. RAYNAUD, citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Folding Paper Boxes, of which the following is a specification.
This invention relates to comer-locks for paste-board boxes orfor their covers. In such constructions it is desirable to provide a safe and secure lock which cannot become self-disengaged and can'only be actually disengaged with considerable difiicult and by intention. As a matter of fact such cornerlocks are intended for permanent enga ement, although of course it is possible to sconnect them.
The present invention has particular reference to the form of the slit by which one member of the two corners is interlocked and enga ed with the other. This slit is of peculiar s ape, one feature being that itis formed entirely u on curved lines ,so that a hook of curved s ape will readily enter it and become interlocked. It has certain other peculiarities of curvilinear shape which constitute positive locking means at both ends of the hook and which will be better understood by reference to the following description in connection with the accompanyingrdrawingsz igure 1 shows a flat surface which includes the two members of a box-comer or of a box-cover corner before they are inter locked; Fi 2 is a pers ective showing similar parts after being foiiied and having their corners interlocked; Fig. 3 is also a perspective but shows .the interior of the corner and the inside appearance of the lock.
In these drawings, 1 and 2 ma be considered two members of a box blan foldable upon the lines 3, 4 and 5 so as to assumethe shape of Fig. 2. Of course Fig. 1 shows the 3 surface which after folding becomes the interior of the box.
The member 1 which I will call the extremit of the side of the box is cut and shape so as to form the curved head 6 having the shoulder 7 all forming a hook. This hook folds around the corner upon the line 4 the side folds u wardly u n the line 3 and the end 2 or a jacent si e as it might correctly be termed, folds upwardly upon the line 5. In this member 2 is formed the peculiar slit which forms the principal feature of my invention. It is in reality a double slit formed entirely in curved lines, and of a shape which I consider to be the best for the convenient engaging and at the same time secure interlocking of the folded corner memhers. is formed on a p ain direct curve which is substantially the arc of a circle whose length is properly calculated to receive the greater part of the head or hook. At one end of this curved slit, which is the end approached by the shoulder 7 is the intersecting slit formed on a double reverse curve 9 11 somewhat in the shape of the letter 8. When the interlocking takes place the shouldered portion of The main ortion 8 of the double slit the hookcan enter freel into the curve 9,
the curved ook cah be engaged with such slits, the consequent saving of time in box making and the security of the comer-lock roduced. Practically a double lock is profiuced by the enga ement of both back and front edges of the 00k with the two curved slots; and the additional strength-ac uiredby means of such double lock gives the ox a longer life and makes it of more permanent value.
What I claim is:
In a comer-lock for boxes and covers, the combination of a member having a tongue, a shoulder or hook upon one side of said tongue and a second member having first, an areshaped slit to receive the main body of the to e, and secondly a slit formed on a dou le reversed curve" said second slit intersecting the arc-shaped slit and lying on both sides of one end of said slit.
In testimony whereof I afiix my in resence of two witnesses, this 15t February 1906.
CHARLES F. RAYNAUD. Witnesses:
F. M. BARTEL, M. R. SEELY.
