Indicia carrying element for marking timber and more particularly logs

Abstract

A indicia carrying element for marking timber and more especially logs possessing a indicia carrying body bearing such indicia and having on one side thereof clips for attachment to the head of an applicator hammer in peripheral grooves therein for prior to driving said element into timber, whereas the other side of the element is provided with spurs to be driven into the timber. The clips are arranged in spring regions like lugs in the plate-like indicia carrying body, and such regions are for instance defined by slots in the indicia carrying body. This means that such indicia carrying elements may be reliably clipped onto the standard head of an applicator hammer without there being any danger of the clips breaking off.

Description

[0001] The invention relates to an indicia carrying element for marking timber and more particularly logs, comprising a tag-like body bearing indicia and from whose one side heel-like clips project for fitting into peripheral recesses in the head of an applicator hammer for attaching the indicia carrying element to timber and whose other side is provided with anchoring spurs to be thrust into the timber.THE PRIOR ART[0002] Such an indicia carrying element, which is normally manufactured of synthetic resin, is disclosed in the British patent publication 2,075,464 A. This prior art indicia carrying element, which reassembles the indicia carrying element illustrated in FIGS. 1 through 3 accompanying the present specification, possesses a rectangular plate-like indicia carrying element, whose four catches or clips for clipping to an applicator hammer stand up from the four corner parts. These projecting clips possess detent projections, directed toward each other, in the upper free term...

AI Technical Summary

Benefits of technology

[0004] One object of the invention is to create a indicia carrying element, which despite having dimensions departing from a standard size owing to properties of its material and its manufacture may be readily clipped on a standard head of an applicator hammer without danger of breakage.

[0006] In the case of the indicia carrying element of the invention the deformation is distributed between the clips and the spring lug regions. This means that the notch fracture effect at the foot of each of the clips is substantially reduced and this in itself substantially prevents any danger of fracture.

[0007] Owing to the elasticity of the spring lug regions the clips may be bent more readily in an outward direction so that even indicia carrying elements, which are really too small, may still be clipped easily that they can be readily taken with the hammer head from a magazine and then be driven into the respective timber.

[0011] In keeping with a preferred form of the invention the spring lug regions are respectively formed by there being at least one slot extending inward from the edge region of the indicia carrying element. This involves the advantage that injection molds only have to be modified to a slight degree and the overall configuration of the indicia carrying elements remains unchanged. It has been found to be particularly convenient to have a design in which each spring lug region is delimited by a slot extending in parallelism to or obliquely at a distance from the long side of the indicia carrying element, such slot having its starting point at one end of the element. The length of the slot can then be selected in accordance with the desired elasticity or flexibility in the spring lug regions formed.

Problems solved by technology

This in turn leads to a situation in which indicia carrying elements with a high degree of shrinkage can only be clipped on the hammer head using substantial force, this entailing a considerable danger of loss of the clips due to a notch-type fracture of same.

This system is however complicated, more especially if a large range of different hammer heads is necessary for different element sizes.

The other possibility, that is to say using a separate injection mold for each type of synthetic resin employed for the indicia carrying elements also leads to substantial expense in manufacture.
