Description
Aiguille de gramophone. L'invention a pour objet une aiguille de gramophone, comportant un fil d'acier serti dans une tige de support, aiguille caractérisée en ce que cette: tige porte une douille filetée dont la position peut être ajustée à la lon gueur de fil que l'on veut faire dépasser.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'aiguille selon l'invention, dans une coupe long2'tu.di- nale suivant l'axe de l'aiguille.
Dans le bout d'une tige de support est serti. un fil d'acier 2. La tige 1 est pourvue d'un filetage, sur lequel est vissée une douille moletée 3 dont le diamètre d'un forage pra tiqué à l'extrémité opposée au taraudage cor respond au diamètre du fil d'acier.
La douille est d'une longueur suffisante pour être, lors de la mise en usage de l'aiguille, engagée par son taraudage avec les premiers filets du filetage de la tige 1, et pour laisser dépasser, par ledit forage, une longueur de fil d'acier suffisante à l'usage que l'on doit faire du tout. Un ressort hélicoïdal 4 s'appuie d'un bout sur un épaulement 5 de la tige et de l'autre sur la douille.
Au cours de l'utilisation de l'aiguille, le fil. d'acier s'use. Pour compenser cette perte en longueur, on visse la douille sur la partie filetée de la tige. Le ressort 4 empêche un déplacement intempestif; il est inutile si la douille est ajustée à frottement gras.
Gramophone needle. The invention relates to a gramophone needle, comprising a steel wire crimped into a support rod, needle characterized in that this: rod carries a threaded sleeve whose position can be adjusted to the length of wire that the 'we want to overtake.
The appended drawing represents, by way of example, an embodiment of the needle according to the invention, in a long2'tu.di- nale section along the axis of the needle.
In the end of a support rod is crimped. a steel wire 2. The rod 1 is provided with a thread, on which is screwed a knurled sleeve 3 whose diameter of a borehole made at the end opposite the thread corresponds to the diameter of the steel wire .
The sleeve is of sufficient length to be, when the needle is put into use, engaged by its tapping with the first threads of the thread of the rod 1, and to allow a length of wire to protrude through said drilling sufficient steel for the use to be made at all. A helical spring 4 rests on one end on a shoulder 5 of the rod and on the other on the sleeve.
During the use of the needle, the thread. steel wears out. To compensate for this loss in length, the sleeve is screwed onto the threaded part of the rod. The spring 4 prevents unwanted displacement; it is unnecessary if the bushing is fitted with a greasy friction.
