Description

Attachment to knives or forks using an aluminum core and a coat made of Britanniametall o. The like. There are already cutlery with solid Metal handle known, in which the handle consists of an aluminum core with a coat of nickel silver or a similar metal is provided, which is the same or has almost the same expansion coefficient as aluminum. Here are both the core and the jacket are each formed from a piece of pipe, which one on top of the other and pushed onto the continuous tang of the knife and then pressed in the die.

It is also the case with metal handles for EB cutlery, which have an aluminum core and a nickel jacket, already known to cast the core around the tang, the sheath being applied to the core by electroplating.

Finally, when it comes to staples for cutlery items made from a wooden core and a coat made of Britannia metal or the like have already been proposed, pour the coat around the wood core.

The subject of the invention, forming the handle attachment to knives or Forks employing an aluminum core and Britannia metal jacket o. The like. On the other hand, consists in that the aluminum core around: the tang of the knife blade or cast around the steerer tube, which can be relatively short, and then the coat turn around. the aluminum core is cast. This way of fastening is simple, and it does not require any pre-machining of the two metals Rollers o., The like. In addition, there is the connection of the core with the tang and that of the jacket with the core by casting an intimate and permanent, and finally arises at Pouring no seam at the end of the handle.

The drawing illustrates one after the new method of attachment manufactured table knife in Fig. z in side view and in A (bbbb. 2 in longitudinal section.

The knife shown consists of the one with a relatively short tang a blade b and the massive handle c, d. The latter is through a core c made of aluminum or an aluminum alloy and surrounding the Erl a a cladding d which surrounds this core and is made of a tin-antimony alloy, the so-called Britannia metal, formed, which has almost the same coefficient of expansion as Owns aluminum. The jacket can have any suitable thickness, wherein but the aluminum core always makes up the bulk of the booklet.

According to: the invention, the aluminum core c is initially around Aden Erl a and then around the aluminum core c rler jacket d made of Britannia metal. This creates an intimate connection between the core and the tang: the blade and on the other side of the mantle reached with the core, so that neither a loosening of the whole There is still a risk of the jacket becoming detached from the core.

The goiter f can, as shown and: known per se, directly be formed on the handle at @, whereby it is achieved that the blade is made of sheet steel or Profile steel can be punched out.

The new way of attaching metal handles is except for table knives also with other knives, e.g. B. fruit knives, kitchen knives o., Like., As well as at Forks applicable. In the latter case, the aluminum core is cast around the steerer tube. If necessary, the conical stem of the fork can form one piece with the handle, so that the fork can also be punched out of sheet steel.
