AIGUILLE ANTI-POUSSIERES ET ANTI-BRUITS.
Aiguille anti-poussières et anti-bruits est destinée :
1) à éviter les fuites d'air par l'aiguille du marteau-piqueurs et conséquemment la production des poussières causées par les fuites du fait de leur projection sur le charbon ou tout autre matière du marteau-piqueur.
2) à étouffer le bruit produit par l'aiguille pendant la marche du marteau-piqueur.
Le plan ci-annexé représente le dispositif en question.
Il consiste en une rainure circulaire creusée dans l'embrase de l'aiguille (outil) des marteaux-piqueurs pour recevoir une bague circulaire en caoutchouc qui forme joint anti-poussières et anti-bruit entre le déca- leur et l'aiguille du marteau-piqueur.
Je demande que soit breveté
Le principe de créer une rainure dans l'embase de l'aiguille pour y loger un joint de caoutchouc ou de tout autre nature de façon à obte- nir un joint d'étanchéité et anti-bruit.

ANTI-DUST AND ANTI-NOISE NEEDLE.
Anti-dust and anti-noise needle is intended for:
1) to avoid air leaks through the jackhammer needle and consequently the production of dust caused by leaks due to their projection on the coal or any other material of the jackhammer.
2) to muffle the noise produced by the needle during the operation of the jackhammer.
The attached plan represents the device in question.
It consists of a circular groove hollowed out in the base of the needle (tool) of the jackhammers to receive a circular rubber ring which forms an anti-dust and anti-noise seal between the decalator and the hammer needle. -picker.
I ask that be patented
The principle of creating a groove in the base of the needle to accommodate a rubber seal or any other type of seal so as to obtain a seal and anti-noise.
