w. F. ROTHERMUND LOCK FOR CARTONS Fild Jan. 6, 1922 INVENTOH' W v A 0mm Patented M ler. l 1924i.
unrrsn stares WERNER F. ROTHERMUND, OF BROOKLYN, NEW YORK, AESSIGNOB T0 THOMPSON & NORRIS COMPANY, OF BROOKLYN. l lEt l' YORF.
LOCK FOR CAR-IDES.
To all whom it may concern:
Be it known that WERNER F. Bornsn- MUND, a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, has invented certain new and useful Improvements in Looks for Cartons, of which the following is a specification.
My invention relates to looks and is especially adapted for use as a lock for a carton of the card board type.
The object of my invention is to provide a lock that can be made of sheet material, such as sheet iron or brass, and that when in use will lie practically flat on the carton.
A further object is to provide a lock that may be attached to the carton flaps when the carton is in its knock-down condition and after the carton is folded into box form, may be locked and cannot be thereafter unlocked without breaking.
A further object is to provide a lock of this character with means whereby the lock can be accurately positioned on the carton flap to insure the interlocking parts coming together accurately when the flaps of tie carton are folded to close the carton.
Referring to the drawings which form a part of this specification;
Figure l is a perspective view of a carton with a lock thereon illustrative of my invention.
Figure 2 is a plan View of a lock member shown partly in section to disclose the catches of the lock.
Figure 3 is a plan view of the interlocking member which engages the member shown in Figure 2.
Figure 4 is a longitudinal sectional view on line l4: of Figures 2 and 3 as it appears when the members are in locked relation on the flaps of a carton.
Figure is a perspective view of the lock with the parts in locked relation and showing the tangs by which the lock is secured to the cart-on.
A, indicates a carton having flap cover portions A--A respectively, which are hinged at B-B respectively.
I C and C indicate the two interlocking portions of the lock, each being made in a single integral piece, stampedand folded by suitable dies into the forms shown.
The lock portion C is first stamped from a sheet to provide the required form of blank Serial No. 527,527,
and is then folded to provide the upper and lower plates l) and E respectively which are spaced apart a distance corresponding to the thickness of the sheet from which the lock is made to provide a space E into which the leaf G projects and is held by the catches ll-H-ll respectively, which enter the openings l-l-l respectively, formed in the leaf G. G.
The catches H. H, etc., act as springs, be ing depressed by the end of'the leaf Gwhen same is forced into the space F, and snapping upward into the openings l -l, etc., when the same are brought into position for engagement so that the edges JJ-J re spectively abut the ends K-K-K respec tively of the spring catches H, as will be readily understood.
The inner end of the lower plate E is bent downward at a right angle to the plane of the plate to form a flange l. which abuts the end of the flay A. and by this means the lock portion is positioned accurately on the flap. The lock portion C may be provided with a raised rib M which serves to limit the travel of the leaf G beyond a predetermined position in the portion C and also serves to guard the edge N thereof. Both portions of the lock are provided with tangs OO--U, etc, by means of which the lock portions are secured to the carton, and on the portion C they overlap the space F and prevent the plates D and E from being forced apart after the lock portion is clamped on the carton. The lower plate E projects beyond the upper plate D as clearly shown at P in Figure 2 so that the end of the leaf G may rest thereon when the flaps A are foldeddownward in the act of closing the carton, and serve as a guide for the l af in entering into locking engagement.
It will be seen that after the carton is once looked it cannot be opened without injury either to the lock or carton, and therefore a person receiving the carton may easily determine whether the carton has been opened or tampered with.
Having thus described my invention I claim as new;
1. A. look of the character described comprisin a member comprising spaced plates one of which has resilient portions extending into the space between said plates, a second member having slots therein adapted to advance between said spaced plates, said slots being adapted to be engaged by said resilient portions.
2. A lock comprising one member comprising a sheet 0t metal bent upon itself so that the space between the bent portions is substantially the thickness of the sheet, resilient projections formed on one of said bent portions and extending into said space, a second member of sheet metal of substan- 1 tially the same thickness as said first member New York and State of New York, this 4th 15 day of November, A. D. 1921.
