SAFETY BOX FASTENER Application filed May 1, 1929.
rlhis invention relates to box fasteners and the improvements are directed to novel and unique means adapted to be associated with a and to be assembled to securely fasten the parts of a box in a manner to discourage unauthorized tampering.-v
Another obj ect is to provide means adapted to be attached to the telescopic members of the ordinary paste-board box, said means cooperating to prevent detachment thereof in the event the sides of said box are'flex'ed by pushing the flexible sides inwardly.
Still another object 0f the invention is to produce a fastening device, comprising simple parts and adapted to'be cheaply manufactured and thus offered to the trade at a most reasonable figure. With these objects in view, together with others which will appear as the description iroceeds, the invention resides in the novel formation, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings and par 5 ticularly pointed out in the claims. In said drawings: Figure 1 is a fragmentary view of a box, including telescopic members, equipped with my 9 invent-ion, the parts being shown in locked.Y

Fig. 7 is a view like unto Fig. 6, but slightly enlarged, and adapted to illustrate a certain spring action which takes place when the parts of the device are being assembled.

Referring now more in particular to the accompanying drawings, wherein like characters of reference denote similar parts throughout the several views, let 10 indicate generally a box adapted to be equipped with myinvention, said box preferably including outer and inner telescopic members,
11 and 12 respectively. In the example illustra-ted, the type of box is formed from paste-board and is adapted to lcontain mens suits or other clothing, it being understood that the same is to be construed as illustrative, rather than restrictive.
The fastening device, forming the subjectmatter of the present application, comprises essentially the part 13, which is adapt-ed to be secured to the sides of the outer member 11, as shown in Fig. 1, the rear portion of said part 13 being apertured, as indicated at 14, (Fig '7) for the reception of suitable fasten- 80 ing devices. The other part 15 of the device is adapted to be secured tothe inner member 12,'said part having a lateral extension 16 which is secured to the bottom ofv said memy ber 12, as shown at 17, the upstanding -por'- 85 tion of said part 15 being arranged in spaced parallel relation to the side of said member 12, as clearly shown in Fig. 2.
With the parts 13 and 15 afxed as aforesaid, the box 10 is placed in the condition 90 shown in Fig. 1, by fitting said outer member 11 over the inner member 12, while the upstanding portion of part 15 is inserted within said part 13, which latter is tubular or sheaflike as indicated in Fig. 6. Thus asthememf bers 11 and 12 are fitted together the upstanding portion of part 15 extends a suitable distance within said part 13, the extent of said insertion depending, ofV course, vupon the number of garments or the like arranged in said ma box 10. In viewof the parallel spacing of part 15 from the side of said member 12, as shown in Fig. 2, the side of themember 11 may readily engage the respective side of the member 12, as will be well understood.V
In order to lock or secure the members 11 and 12 in position, and to prevent the unauthorized opening of the box, it is proposed to provide means whereby said parts 13 and 15 maybe secured in assembled relation. To'this end, said part 15 is provided with a plurality of headed projections 18, includin(y neck portions 19, while the outer face portion of said part 13 is slit longitudinally, as indicated at 20, the width of the slit 'being slightly less than the diameter of said neck portions 19. Upon inspection of Figs. 1 and 5, it will be noted that angular slots 21 communicate with said slit 20, said slots being spaced therealong to agree with the spacing of said projections 18 on said part 15, and further the lowerV end of said slit 20 leads from a notch 22 arranged at the lower end of the outer face of said part 13.
From the foregoing it is apparent that as the part 15 is inserted within the part 13, the neck portion 19 of the top projection 18 enters the notch 22 in part 13, and though the ywidth of said slit 20 is slightly less than the width ordiameter of said neck portion 19, the natural spring of resiliencyof the faceportion of said part 13, permits a slight iiexing so that said neck portion 19 may pass along said slit until it reaches the first angular slot 21. The flexing, aforementioned, will be readily understood upon inspection of F igfr' As the-top projection reaches the first angular slot 21, a continued tting of the members 11 and 12, forces the succeeding neck portions 19 through the slit 20, as aforesaid, until said projections engage the slots 21 as indicated in Fig. 1. The abovecondition obviouslyk exists when the members 11 and V12 are intimately engaged, that is, whenever the box contains a single suit of clothes or the like. However, in the event a large number of `pieces are. packedA in the box, the
members 11 and 12 will notengage so intimately as shown in Fig. 1, and in this kcondition it is probable that but one or two of the projections 18 will cooperate with a like i number of slots 21 in said `part 13; For
this reason a plurality of cooperating projections and slots are provided. VWhen the neck portions 19 vare engaged in selected slots 21, the slit 20, previously expended, resumes its normal width, and hence an attempt to open the box is frustrated since the angular arrangement of said slots 21 precludes a reinsertion of said neck portions 19. in said slit f 20. Obviously, an attempted forcing of the opening would cause the neck portions to ride downwardly into the slots 21 as shown in Fig. 8, and since the parts 13 and'15 are made from relatively thin material a distortion of the would occur.
It will be seen that my improved device will readily supersede the usual tying or sealing, and since forceful entry into the box parts, readily discernible,
cannot be had without leaving evidence of tails of construction, proportion and arrangement of parts may be resorted to without j departingfromthe spirit of the invention asdefined in the appended claims.
