Application filed September 16, 1920. I Serial No. 410,601.

To all whom it may concern:

. formed Wit Be it known that I, FRANK Monnswoirrrr, of 10 King Street, Arch Hill, Auckland, in the Provincial District of Auckland, in the Dominion of New Zealand, a subject of the King of- Great Britain and Ireland, have invented certain new and useful Improvements in an Improved Nail for Packing Cases and the like, of which the following- .the entrance of the nail into the wood,

is a specification.

This invention provides an lmproved nail especially adapted for use as a fastening in the construction and securing of packing,

cases and the like from which it is desired to prevent pilfering,

Accordin a solid lower portion, the remaining portion being hollow. i

A head is provided around the upper end of the hollow portion and the lower portion besides being pointed to facilitate the entrance of the nail into the wood, is also: pro ects uppointed at its upperend which: wards into said hollow portion.

-A. member splitinto legs is housed in the hollow portion, the latter bein vided with side opening level wit the pointed upper end of the solid portion. The legsof the split member are sharp ened on the inner sidesof their lower ends wards in the hollow portion, after the nail has been driven into the wood, said legs comin are so arated and spread outwards through the side openings in the hollow portion, by incontact with the pointed upper end 0 the solid portion and enter the wood, thereby providing anchoring means, which prevents said nail from being withdrawn or the board "secured thereby from being removed, except by splitting or otherwise damaging the wood. The invention will'be more particularly described in conjunction with'the accompanying drawing, in which:-'

Figure 1 is an enlarged sectional elevation of a portion of a case showing a nail secured therein.

Figure 2 is a part sectional elevation of the'same nail on a larger scale, but be- .fore the split member-isptorced downwards to the invention, the nail is pro.

Figure 6 is an elevation of a nail in which the hollow and solid portions are integral and showing the legs of the split member emerging from the hollow portion.

In the. drawing, 1 is the'solid lower portion of the nail and 2 the hollow portion i the latter being provided with a .head 3 around ts upper end and the former besides being pointed in order to facilitate having a concave conical upper-end 4 which pro ects upwards into the hollow ortion 2. The member 5 housed within t e hollow portion 2, is split for the greater part of its length into legs'fi, each of which is sharpened atthe inner side of its lower en cave conical end 4 of the portion 1.

The solid portion 1 can be screwed into the hollow portion 2 and be. provided with a shoulder or shoulders 8 for the lower end of the portion 2 to bear against, as in Figiures 1 and 2, or it can have a groove or portion 1 being of a concave conical formation, a concave knife edge end 4 can be I 90 When nailing two pieces of wood together,

provided as shown in Figures 4 and 5.

For eathleg 6, a side opening 7 is provided 1n the portion 2 level with the'consay for instance the end of a lid 10 to a .case end 11, the member '5 is completely housed in the hollow portion 2, with the lower ends of the le s 6 resting on the pointed upper end of t e solid portion 1.

After the nail has been driven right home, the member 5' is punched or otherwise forced downwards in the hollow portion 2,

whereupon the legs -6 owing to'the shape of their lower ends and to the pointed upper end of the solidportion 1, are caused to separateand spread outwards through the openings 7 v and bury themselves in the case en 1 The shape of the ends of said legs also causes-same to take an upward path through 4 the. wood with the result that the nail becomes securely anchored in the case end 11 as shown.

. i I The nail cannot be withdrawn and the {board orthe like it secures cannot be re,

moved except by splitting the wood, or leaving other tell tale evidence of pilfering.

Having now particularly descnbed and ascertained the nature of this invention and in what manner the same is to be performed I deolare that what I claim is A non-removable nail comprising a hollow tubular member having a head at its upper end and a pair of dlametricallyopposite holes at its lower end; a solid pierc- 1 ing member separate from said hollow member and reduced at its upper end to fit and be secured to the hollow member, said re duced portion of the solid piercing member having a pair of cam surfaces one for each hole, said piercing member having a sharpened point at its othervend; and an anchoring member mounted within said FRANK MOLESWORTH.
